How to Apply Assignment Methods that were Developed for Vehicular
  Traffic to Pedestrian Microsimulations

abstract:
  Applying assignment methods to compute user-equilibrium route choice is very
common in traffic planning. It is common sense that vehicular traffic arranges
in a user-equilibrium based on generalized costs in which travel time is a
major factor. Surprisingly travel time has not received much attention for the
route choice of pedestrians. In microscopic simulations of pedestrians the
vastly dominating paradigm for the computation of the preferred walking
direction is set into the direction of the (spatially) shortest path. For
situations where pedestrians have travel time as primary determinant for their
walking behavior it would be desirable to also have an assignment method in
pedestrian simulations. To apply existing (road traffic) assignment methods
with simulations of pedestrians one has to reduce the nondenumerably many
possible pedestrian trajectories to a small subset of routes which represent
the main, relevant, and significantly distinguished routing alternatives. All
except one of these routes will mark detours, i.e. not the shortest connection
between origin and destination. The proposed assignment method is intended to
work with common operational models of pedestrian dynamics. These - as
mentioned before - usually send pedestrians into the direction of the spatially
shortest path. Thus, all detouring routes have to be equipped with intermediate
destinations, such that pedestrians can do a detour as a piecewise connection
of segments on which they walk into the direction of the shortest path. One has
then to take care that the transgression from one segment to the following one
no artifacts are introduced into the pedestrian trajectory.

Subcanonical points on projective curves and triply periodic minimal
  surfaces in the Euclidean space

abstract:
  A point $p$ on a smooth complex projective curve $C$ of genus $g>3$ is
subcanonical if the divisor $(2g-2)p$ is canonical. In the moduli space of
pointed curves, the subcanonical locus is described by pairs $(C,p)$ as above,
and it consists of three irreducible components of dimension $2g-1$. Apart from
the hyperelliptic component $\mathcal{G}_g^{hyp}$, the other components
$\mathcal{G}_g^{odd}$ and $\mathcal{G}_g^{even}$ depend on the parity of
$h^0(C,(g-1)p)$, and their general points satisfy $h^0(C,(g-1)p)=1$ and $2$,
respectively. In this paper, we study the subloci of pairs $(C,p)$ such that
$h^0(C,(g-1)p)$ is at least $r+1$ and it has the same parity as $r+1$. In
particular, we provide a lower bound on their dimension, and we prove its
sharpness for $r<4$. As an application, we further give an existence result for
triply periodic minimal surfaces immersed in the 3-dimensional Euclidean space,
completing a previous result of the second author.


title:
Exponentially small lower bounds for the splitting of separatrices to
  whiskered tori with frequencies of constant type

abstract:
  We study the splitting of invariant manifolds of whiskered tori with two
frequencies in nearly-integrable Hamiltonian systems, such that the hyperbolic
part is given by a pendulum. We consider a 2-dimensional torus with a fast
frequency vector $\omega/\sqrt\epsilon$, with $\omega=(1,\Omega)$ where
$\Omega$ is an irrational number of constant type, i.e. a number whose
continued fraction has bounded entries. Applying the Poincar\'e-Melnikov
method, we find exponentially small lower bounds for the maximal splitting
distance between the stable and unstable invariant manifolds associated to the
invariant torus, and we show that these bounds depend strongly on the
arithmetic properties of the frequencies.


title:
Negative Differential Resistance due to Nonlinearities in Single and
  Stacked Josephson Junctions

abstract:
  Josephson junction systems with a negative differential resistance play an
essential role for applications. As a well known example, long Josephson
junctions of the BSCCO type have been considered as a source of THz radiation
in recent experiments. Numerical results for the dynamics of the fluxon system
have demonstrated that a cavity induced negative differential resistance plays
a crucial role for the emission of electromagnetic radiation. We consider the
case of a negative differential resistance region in the McCumber curve itself
of a single junction and found that it has an effect on the emission of
electromagnetic radiation. Two different shapes of negative differential
resistance region are considered and we found it is essential to distinguish
between current bias and voltage bias.


title:
Solutions of the Bethe-Salpeter Equation in Minkowski space: a
  comparative study

abstract:
  The Bethe-Salpeter Equation for a two-scalar, S-wave bound system,
interacting through a massive scalar, is investigated within the ladder
approximation. By assuming a Nakanishi integral representation of the
Bethe-Salpeter amplitude, one can deduce new integral equations that can be
solved and quantitatively studied, overcoming the analytic difficulties of the
Minkowski space.
  Finally, it is shown that the Light-front distributions of the valence state,
directly obtained from the Bethe-Salpeter amplitude, open an effective window
for studying the two-body dynamics.


title: Hyperscaling above the upper critical dimension

abstract:
  Above the upper critical dimension, the breakdown of hyperscaling is
associated with dangerous irrelevant variables in the renormalization group
formalism at least for systems with periodic boundary conditions. While these
have been extensively studied, there have been only a few analyses of
finite-size scaling with free boundary conditions. The conventional expectation
there is that, in contrast to periodic geometries, finite-size scaling is
Gaussian, governed by a correlation length commensurate with the lattice
extent. Here, detailed numerical studies of the five-dimensional Ising model
indicate that this expectation is unsupported, both at the infinite-volume
critical point and at the pseudocritical point where the finite-size
susceptibility peaks. Instead the evidence indicates that finite-size scaling
at the pseudocritical point is similar to that in the periodic case. An
analytic explanation is offered which allows hyperscaling to be extended beyond
the upper critical dimension.


title: Two scenarios for quantum multifractality breakdown

abstract:
  We expose two scenarios for the breakdown of quantum multifractality under
the effect of perturbations. In the first scenario, multifractality survives
below a certain scale of the quantum fluctuations. In the other one, the
fluctuations of the wave functions are changed at every scale and each
multifractal dimension smoothly goes to the ergodic value. We use as generic
examples a one-dimensional dynamical system and the three-dimensional Anderson
model at the metal-insulator transition. Based on our results, we conjecture
that the sensitivity of quantum multifractality to perturbation is universal in
the sense that it follows one of these two scenarios depending on the
perturbation. We also discuss the experimental implications.

Spectroscopy Apparatus for the Measurement of The Hyperfine Structure of
  Antihydrogen

abstract:
  The ASACUSA CUSP collaboration at the Antiproton Decelerator (AD) of CERN is
planning to measure the ground-state hyperfine splitting of antihydrogen using
an atomic spectroscopy beamline. We describe here the latest developments on
the spectroscopy apparatus developed to be coupled to the antihydrogen
production setup (CUSP).


title:
A Duality Transform for Constructing Small Grid Embeddings of 3d
  Polytopes

abstract:
  We study the problem of how to obtain an integer realization of a 3d polytope
when an integer realization of its dual polytope is given. We focus on grid
embeddings with small coordinates and develop novel techniques based on Colin
de Verdi\`ere matrices and the Maxwell-Cremona lifting method. We show that
every truncated 3d polytope with n vertices can be realized on a grid of size
O(n^{9log(6)+1}). Moreover, for every simplicial 3d polytope with n vertices
with maximal vertex degree {\Delta} and vertices placed on an L x L x L grid, a
dual polytope can be realized on an integer grid of size O(n L^{3\Delta + 9}).
This implies that for a class C of simplicial 3d polytopes with bounded vertex
degree and polynomial size grid embedding, the dual polytopes of C can be
realized on a polynomial size grid as well.


title: Network Sampling Based on NN Representatives

abstract:
  The amount of large-scale real data around us increase in size very quickly
and so does the necessity to reduce its size by obtaining a representative
sample. Such sample allows us to use a great variety of analytical methods,
whose direct application on original data would be infeasible. There are many
methods used for different purposes and with different results. In this paper
we outline a simple and straightforward approach based on analyzing the nearest
neighbors (NN) that is generally applicable. This feature is illustrated on
experiments with weighted networks and vector data. The properties of the
representative sample show that the presented approach maintains very well
internal data structures (e.g. clusters and density). Key technical parameters
of the approach is low complexity and high scalability. This allows the
application of this approach to the area of big data.


title: Geometry-induced fluctuations of olfactory searches in bounded domains

abstract:
  In olfactory search an immobile target emits chemical molecules at constant
rate. The molecules are transported by the medium which is assumed to be
turbulent. Considering a searcher able to detect such chemical signals and
whose motion follows the infotaxis strategy, we study the statistics of the
first-passage time to the target when the searcher moves on a finite
two-dimensional lattice of different geometries. Far from the target, where the
concentration of chemicals is low the direction of the searcher's first
movement is determined by the geometry of the domain and the topology of the
lattice, inducing strong fluctuations on the average search time with respect
to the initial position of the searcher. The domain is partitioned in well
defined regions characterized by the direction of the first movement. If the
search starts over the interface between two different regions, large
fluctuations in the search time are observed.

title: 2013 Update of the discoveries of nuclides

abstract:
  The 2013 update of the discovery of nuclide project is presented. Details of
the 12 new nuclides observed for the first time in 2013 are described. In
addition, the discovery of 266Db has been included and the previous assignments
of 6 other nuclides were changed. Overview tables of where and how nuclides
were discovered have also been updated and are discussed.


title: The UTfit Collaboration Average of $D$ meson mixing data: Winter 2014

abstract:
  We update the analysis of $D$ meson mixing including the latest experimental
results as of January 2014. We derive constraints on the parameters $M_{12}$,
$\Gamma_{12}$ and $\Phi_{12}$ that describe $D$ meson mixing using all
available data, allowing for CP violation. We also provide posterior
distributions for observable parameters appearing in $D$ physics.


title: On the stable Conley index in Hilbert spaces

abstract:
  In this paper, we study Conley theory in Hilbert spaces and make some
refinement of the construction of the stable Conley index developed by
G\c{e}ba, Izydorek, and Pruszko. For instance, we allow subspaces other than
invariant subspaces in the the construction. As a main result, we show that the
resulting stable Conley index for a given isolating neighborhood of a flow does
not depend on choices in the construction. We also hope that some results can
be applied to the construction of Floer homotopy type.


title:
Turbulent metal-silicate mixing, fragmentation, and equilibration in
  magma oceans

abstract:
  Much of the Earth was built by high-energy impacts of planetesimals and
embryos, many of these impactors already differentiated, with metallic cores of
their own. Geochemical data provide critical information on the timing of
accretion and the prevailing physical conditions, but their interpretation
depends critically on the degree of metal-silicate chemical equilibration
during core-mantle differentiation, which is poorly constrained. Efficient
equilibration requires that the large volumes of iron derived from impactor
cores mix with molten silicates down to scales small enough to allow fast
metal-silicate mass transfer. Here we use fluid dynamics experiments to show
that large metal blobs falling in a magma ocean mix with the molten silicate
through turbulent entrainment, with fragmentation into droplets eventually
resulting from the entrainment process. In our experiments, fragmentation of
the dense fluid occurs after falling a distance equal to 3-4 times its initial
diameter, at which point a sizable volume of ambient fluid has already been
entrained and mixed with the dense falling fluid. Contrary to what has usually
been assumed, we demonstrate that fragmentation of the metallic phase into
droplets may not be required for efficient equilibration: turbulent mixing, by
drastically increasing the metal-silicate interfacial area, may result in fast
equilibration even before fragmentation. Efficient re-equilibration is
predicted for impactors of size small compared to the magma ocean depth. In
contrast, a much smaller re-equilibration degree is predicted in the case of
large impacts for which the impactor core diameter approaches the magma ocean
thickness.


title: Pl\"ucker varieties and higher secants of Sato's Grassmannian

abstract:
  Every Grassmannian, in its Pl\"ucker embedding, is defined by quadratic
polynomials. We prove a vast, qualitative, generalisation of this fact to what
we call Pl\"ucker varieties. A Pl\"ucker variety is in fact a family of
varieties in exterior powers of vector spaces that, like the Grassmannian, is
functorial in the vector space and behaves well under duals. A special case of
our result says that for each fixed natural number k, the k-th secant variety
of any Pl\"ucker-embedded Grassmannian is defined in bounded degree independent
of the Grassmannian. Our approach is to take the limit of a Pl\"ucker variety
in the dual of a highly symmetric space known as the infinite wedge, and to
prove that up to symmetry the limit is defined by finitely many polynomial
equations. For this we prove the auxilliary result that for every natural
number p the space of p-tuples of infinite-by-infinite matrices is Noetherian
modulo row and column operations. Our results have algorithmic counterparts:
every bounded Pl\"ucker variety has a polynomial-time membership test, and the
same holds for Zariski-closed, basis-independent properties of p-tuples of
matrices.


title: Evaluation of YTEX and MetaMap for clinical concept recognition

abstract:
  We used MetaMap and YTEX as a basis for the construc- tion of two separate
systems to participate in the 2013 ShARe/CLEF eHealth Task 1[9], the
recognition of clinical concepts. No modifications were directly made to these
systems, but output concepts were filtered using stop concepts, stop concept
text and UMLS semantic type. Con- cept boundaries were also adjusted using a
small collection of rules to increase precision on the strict task. Overall
MetaMap had better per- formance than YTEX on the strict task, primarily due to
a 20% perfor- mance improvement in precision. In the relaxed task YTEX had
better performance in both precision and recall giving it an overall F-Score
4.6% higher than MetaMap on the test data. Our results also indicated a 1.3%
higher accuracy for YTEX in UMLS CUI mapping.


title: Summability in general Carleman ultraholomorphic classes

abstract:
  A definition of summability is put forward in the framework of general
Carleman ultraholomorphic classes in sectors, so generalizing $k-$summability
theory as developed by J.-P. Ramis. Departing from a strongly regular sequence
of positive numbers, we construct an associated analytic proximate order and
corresponding kernels, which allow us to consider suitable Laplace and
Borel-type transforms, both formal and analytic, whose behavior closely
resembles that of the classical ones in the Gevrey case. An application to the
study of the summability properties of the formal solutions to some
moment-partial differential equations is included.


title: Hierarchical organization versus self-organization

abstract:
  In this paper we try to define the difference between hierarchical
organization and self-organization. Organization is defined as a structure with
a function. So we can define the difference between hierarchical organization
and self-organization both on the structure as on the function. In the next two
chapters these two definitions are given. For the structure we will use some
existing definitions in graph theory, for the function we will use existing
theory on (self-)organization. In the third chapter we will look how these two
definitions agree. Finally we give a conclusion.


title:
Coherent medium-induced gluon radiation in hard forward $1\to 1$
  partonic processes

abstract:
  We revisit the medium-induced coherent radiation associated to hard and
forward (small angle) scattering of an energetic parton through a nuclear
medium. We consider all $1\to 1$ hard forward processes ($g \to g$, $q \to q$,
$q \to g$ and $g \to q$), and derive the energy spectrum of induced coherent
radiation rigorously to all orders in the opacity expansion and for the
specific case of a Coulomb scattering potential. We obtain a simple general
formula for the induced coherent spectrum, which encompasses the results
corresponding to previously known special cases.


title: Elementary Wideband Timing of Radio Pulsars

abstract:
  We present an algorithm for the simultaneous measurement of a pulse
time-of-arrival (TOA) and dispersion measure (DM) from folded wideband pulsar
data. We extend the prescription from Taylor (1992) to accommodate a general
two-dimensional template "portrait", the alignment of which can be used to
measure a pulse phase and DM. We show that there is a dedispersion reference
frequency that removes the covariance between these two quantities, and note
that the recovered pulse profile scaling amplitudes can provide useful
information. We experiment with pulse modeling by using a Gaussian-component
scheme that allows for independent component evolution with frequency, a
"fiducial component", and the inclusion of scattering. We showcase the
algorithm using our publicly available code on three years of wideband data
from the bright millisecond pulsar J1824-2452A (M28A) from the Green Bank
Telescope, and a suite of Monte Carlo analyses validates the algorithm. By
using a simple model portrait of M28A we obtain DM trends comparable to those
measured by more standard methods, with improved TOA and DM precisions by
factors of a few. Measurements from our algorithm will yield precisions at
least as good as those from traditional techniques, but is prone to fewer
systematic effects and is without ad hoc parameters. A broad application of
this new method for dispersion measure tracking with modern large-bandwidth
observing systems should improve the timing residuals for pulsar timing array
experiments, like the North American Nanohertz Observatory for Gravitational
Waves.


title: Non-Orthogonal Tensor Diagonalization

abstract:
  Tensor diagonalization means transforming a given tensor to an exactly or
nearly diagonal form through multiplying the tensor by non-orthogonal
invertible matrices along selected dimensions of the tensor. It is
generalization of approximate joint diagonalization (AJD) of a set of matrices.
In particular, we derive (1) a new algorithm for symmetric AJD, which is called
two-sided symmetric diagonalization of order-three tensor, (2) a similar
algorithm for non-symmetric AJD, also called general two-sided diagonalization
of an order-3 tensor, and (3) an algorithm for three-sided diagonalization of
order-3 or order-4 tensors. The latter two algorithms may serve for canonical
polyadic (CP) tensor decomposition, and they can outperform other CP tensor
decomposition methods in terms of computational speed under the restriction
that the tensor rank does not exceed the tensor multilinear rank. Finally, we
propose (4) similar algorithms for tensor block diagonalization, which is
related to the tensor block-term decomposition.


title: A Hybrid Pricing Framework for TV White Space Database

abstract:
  According to the recent rulings of the Federal Communications Commission
(FCC), TV white spaces (TVWS) can now be accessed by secondary users (SUs)
after a list of vacant TV channels is obtained via a geo-location database.
Proper business models are therefore essential for database operators to manage
geo-location databases. Database access can be simultaneously priced under two
different schemes: the registration scheme and the service plan scheme. In the
registration scheme, the database reserves part of the TV bandwidth for
registered White Space Devices (WSDs). In the service plan scheme, the WSDs are
charged according to their queries. In this paper, we investigate the business
model for the TVWS database under a hybrid pricing scheme. We consider the
scenario where a database operator employs both the registration scheme and the
service plan scheme to serve the SUs. The SUs' choices of different pricing
schemes are modeled as a non-cooperative game and we derive distributed
algorithms to achieve Nash Equilibrium (NE). Considering the NE of the SUs, the
database operator optimally determines pricing parameters for both pricing
schemes in terms of bandwidth reservation, registration fee and query plans.


title: Rationality problem for transitive subgroups of S_8

abstract:
  For any field K and any transitive subgroup G of S_8, let G acts naturally on
K(x_1, . . ., x_8) by permutations of the variables, we prove that under some
minor conditions K(x_1, . . ., x_8)^G is always K-rational except G is A_8 or G
is isomorphic to PGL(2, 7). We pay special attentions on the characteristic 2
cases.


title:
Solar Energetic Particles and Associated EIT Disturbances in Solar Cycle
  23

abstract:
  We explore the link between solar energetic particles (SEPs) observed at 1 AU
and large-scale disturbances propagating in the solar corona, named after the
Extreme ultraviolet Imaging Telescope (EIT) as EIT waves, which trace the
lateral expansion of a coronal mass ejection (CME). A comprehensive search for
SOHO/EIT waves was carried out for 179 SEP events during Solar Cycle 23
(1997-2006). 87% of the SEP events were found to be accompanied by EIT waves.
In order to test if the EIT waves play a role in the SEP acceleration, we
compared their extrapolated arrival time at the footpoint of the Parker spiral
with the particle onset in the 26 eastern SEP events that had no direct
magnetic connection to the Earth. We find that the onset of proton events was
generally consistent with this scenario. However, in a number of cases the
first near-relativistic electrons were detected too early. Furthermore, the
electrons had in general only weakly anisotropic pitch-angle distributions.
This poses a problem for the idea that the SEPs were accelerated by the EIT
wave or in any other spatially confined region in the low corona. The presence
of weak electron anisotropies in SEP events from the eastern hemisphere
suggests that transport processes in interplanetary space, including
cross-field diffusion, play a role in giving the SEPs access to a broad range
of helio-longitudes.


title: Bounds on non-adiabatic evolution in single-field inflation

abstract:
  We examine the regime of validity of $N$-point spectra predictions of single
field inflation models that invoke transient periods of non-adiabatic
evolution. Such models generate oscillatory features in these spectra spanning
frequencies up to the inverse time scale of the transient feature. To avoid
strong coupling of fluctuations in these theories this scale must be at least
$\sim 10^{-2}/c_s$ of the Hubble time during inflation, where $c_s$ is the
inflaton sound speed. We show that, in such models, the signal-to-noise ratio
of the bispectrum is bounded from above by that of the power spectrum, implying
that searches for features due to non-adiabatic evolution are best focussed
first on the latter.


title: Decoherence-assisted spectroscopy of a single Mg$^+$ ion

abstract:
  We describe a high-resolution spectroscopy method, in which the detection of
single excitation events is enhanced by a complete loss of coherence of a
superposition of two ground states. Thereby, transitions of a single isolated
atom nearly at rest are recorded efficiently with high signal-to-noise ratios.
Spectra display symmetric line shapes without stray-light background from
spectroscopy probes. We employ this method on a $^{25}$Mg$^+$ ion to measure
one, two, and three-photon transition frequencies from the 3S ground state to
the 3P, 3D, and 4P excited states, respectively. Our results are relevant for
astrophysics and searches for drifts of fundamental constants. Furthermore, the
method can be extended to other transitions, isotopes, and species. The
currently achieved fractional frequency uncertainty of $5 \times 10^{-9}$ is
not limited by the method.


title:
Qualitative behavior for flux-saturated mechanisms: Traveling waves,
  waiting time and smoothing effects

abstract:
  This paper is devoted to the analysis of qualitative properties of
flux-saturated type operators in dimension one. Specifically, we study
regularity properties and smoothing effects, discontinuous interfaces, the
existence of traveling wave profiles, sub- and super-solutions and waiting time
features. The aim of the paper is to better understand these kind of phenomena
throughout two prototypic operators: The relativistic heat equation and the
porous media flux-limited equation. As an important consequence of our results
we deduce that solutions to the one-dimensional relativistic heat equation
become smooth inside their support on the long time run.


title: The role of turbulence in star formation laws and thresholds

abstract:
  The Schmidt-Kennicutt relation links the surface densities of gas to the star
formation rate in galaxies. The physical origin of this relation, and in
particular its break, i.e. the transition between an inefficient regime at low
gas surface densities and a main regime at higher densities, remains debated.
Here, we study the physical origin of the star formation relations and breaks
in several low-redshift galaxies, from dwarf irregulars to massive spirals. We
use numerical simulations representative of the Milky Way, the Large and the
Small Magellanic Clouds with parsec up to subparsec resolution, and which
reproduce the observed star formation relations and the relative variations of
the star formation thresholds. We analyze the role of interstellar turbulence,
gas cooling, and geometry in drawing these relations, at 100 pc scale. We
suggest in particular that the existence of a break in the Schmidt- Kennicutt
relation could be linked to the transition from subsonic to supersonic
turbulence and is independent of self-shielding effects. This transition being
connected to the gas thermal properties and thus to the metallicity, the break
is shifted toward high surface densities in metal-poor galaxies, as observed in
dwarf galaxies. Our results suggest that together with the collapse of clouds
under self-gravity, turbulence (injected at galactic scale) can induce the
compression of gas and regulate star formation.

Color octet neutrino as the source of the IceCube PeV energy neutrino
  events

abstract:
  It is shown that two PeV events observed by the IceCube collaboration can be
interpreted as resonance production of color octet neutrinos.


title: How Many Beamforming Vectors Generate the Same Beampattern?

abstract:
  In this letter, we address the fundamental question of how many beamforming
vectors exist which generate the same beampattern? The question is relevant to
many fields such as, for example, array processing, radar, wireless
communications, data compression, dimensionality reduction, and biomedical
engineering. The desired property of having the same beampattern for different
columns of a beamspace transformation matrix (beamforming vectors) often plays
a key importance in practical applications. The result is that at most
2^{M-1}-1 beamforming vectors with the same beampattern can be generated from
any given beamforming vector. Here M is the dimension of the beamforming
vector. At the constructive side, the answer to this question allows for
computationally efficient techniques for the beamspace transformation design.
Indeed, one can start with a single beamforming vector, which gives a desired
beampattern, and generate a number of other beamforming vectors, which give
absolutely the same beampattern, in a computationally efficient way. We call
the initial beamforming vector as the mother beamforming vector. One possible
procedure for generating all possible new beamforming vectors with the same
beampattern from the mother beamforming vector is proposed. The application of
the proposed analysis to the transmit beamspace design in multiple-input
multiple-output radar is also given.

Homeland Defense and Security Universal Interface Software (HDUIS)
  Protocol Communication Gateway UIS Protocol Enhancements, Alterations and
  Attachments

abstract:
  The Universal Interface Software(UIS) Protocol was a Theater Missile Defense
Gateway Protocol which linked the Strategic Defense Initiative(SDI)
Architecture Killer Satellite Software Protocol to the National Test Bed
Simulation Software Protocol to enable neural network shock loop operation when
ICBMS were approaching the SDI Shield. A Gateway Software is required for
Homeland Defense and Security Systems to communicate the sensor information
from hardware and software boxes at airports and government buildings and other
locations to the Global Information Grid(GIG). Therefore, a Homeland Defense
and Security UIS(HDSUIS) Protocol is achieved by UIS conversion to HDSUIS for
Thresholds Stabilization and GIG and terrorist sensor Enhancements, Homeland
Defense and Security Lagrangian equation and GIG simulation facility timing
chart Alterations, and two Catastrophe Theory Protocol Attachments to the UIS
Geometric software structure inner cube. This UIS Protocol conversion to the
HDSUIS Protocol will track and provide a Congestion Controlled, i.e.,prevention
of deadlock and livelock, communication of (1) Shoe bombers and copycat shoe
bombers, (2) deeply buried and imbedded boxes with explosives, (3) damage to
lase1 equipment, (4) shoulder missile fired armament, and (5) surface to air
missiles from their sensor equipment to the Global Information Grid with
Theater Missile Defense Characteristics. The Homeland Defense and Security
GNNO(Geometric Neural Network Overlay) Protocol will be derived as a conversion
of the UIS GNNO Protocol.

Ferroic properties of Fe-doped and Cu-doped K0.45Na0.49Li0.06NbO3
  ceramics

abstract:
  Ferroelectric and magnetic properties of Fe-doped K0.45Na0.49Li0.06NbO3
(KNLN) and Cu-doped KNLN ceramics were investigated. Comparing with pure KNLN
ceramic, Fe-doped KNLN shows ferromagnetic and ferroelectric properties
simultaneously while Cu-doped KNLN shows stronger diamagnetic and ferroelectric
properties. The magnetic property in KNLN matrix are believed to be induced by
point defects. The ferromagnetism of Fe-doped KNLN can be explained by the
F-center exchange mechanism, while the antiferroelectric-like loop and
diamagnetism of Cu-doped KNLN was explained by the special defect structure and
Cu1+ ion at A site.

Effects of Structural Distortion Induced by Sc Substitution in
  LuFe$_2$O$_4$

abstract:
  We have studied the correlation between the structural distortion and the
electronic/magnetic properties in single-crystalline (Lu,Sc)Fe$_2$O$_4$
(Sc=0.05 and 0.3) by using X-ray diffraction (XRD), magnetic susceptibility,
and X-ray absorption spectroscopy (XAS)/x-ray magnetic circular dichroism
(XMCD)measurements. The Rietveld structure analysis of the XRD patterns
revealed that the Sc substitution induced an elongation of the FeO$_5$
bipyramidal cages in LuFe$_2$O$_4$ and increased the Fe$_2$O$_4$ bilayer
thickness. A non-negligible decrease in the ferrimagnetic transition
temperature T$_C$ is observed in the magnetic susceptibility curve of the
Sc=0.3 sample, but the XAS/XMCD spectra do not show any difference except for a
small reduction of dichroism signals at the Fe$^{3+}$ absorption edge. We
interpret this suppression of T$_C$ to be the result of a decreased spin-orbit
coupling effect in the Fe$^{2+}$ $e_{1g}$ doublet under $D_{3h}$ symmetry,
which is induced by the weakened structural asymmetry of the FeO$_5$
bipyramids.


title: A Note on the CFT Origin of the Strong Constraint of DFT

abstract:
  In double field theory, motivated by its field theoretic consistency, the
level matching condition is generalized to the so-called strong constraint. In
this note, it is investigated what the two-dimensional conformal field theory
origin of this constraint is. Initially treating the left- and right-movers as
independent, we compute the torus partition function as well as a generalized
Virasoro-Shapiro amplitude. In non-compact directions the strong constraint
arises from the factorization of the Virasoro-Shapiro amplitude over physical
states as determined by the modular invariant partition function. From the same
argument, along internal toroidal directions, no analogous constraint arises.


title:
Age Determination of Fifteen Old to Intermediate-Age Small Magellanic
  Cloud Star Clusters

abstract:
  We present CMDs in the V and I bands for fifteen star clusters in the Small
Magellanic Cloud (SMC) based on data taken with the Very Large Telescope (VLT,
Chile). We selected these clusters from our previous work, wherein we derived
cluster radial velocities and metallicities from Calcium II infrared triplet
(CaT) spectra also taken with the VLT. We discovered that the ages of six of
our clusters have been appreciably underestimated by previous studies, which
used comparatively small telescopes, graphically illustrating the need for
large apertures to obtain reliable ages of old and intermediate-age SMC star
clusters. In particular, three of these clusters, L4, L6 and L110, turn out to
be amongst the oldest SMC clusters known, with ages of 7.9 +- 1.1, 8.7 +- 1.2
and 7.6 +- 1.0 Gyr, respectively, helping to fill a possible "SMC cluster age
gap" (Glatt et al. 2008). Using the present ages and metallicities from Parisi
et al. (2009), we analyze the age distribution, age gradient and age
metallicity relation (AMR) of a sample of SMC clusters measured homogeneously.
There is a suggestion of bimodality in the age distribution but it does not
show a constant slope for the first 4 Gyr (Piatti 2011), and we find no
evidence for an age gradient. Due to the improved ages of our cluster sample,
we find that our AMR is now better represented in the intermediate/old period
than that we derived in Parisi et al. (2009), where we simply took ages
available in the literature. Additionally, clusters younger than aprox. 4 Gyr
now show better agreement with the bursting model, but we confirm that this
model is not a good representation of the AMR during the intermediate-age/old
period. A more complicated model is needed to explain the SMC chemical
evolution in that period.


title: Chern-Simons-like Gravity Theories

abstract:
  A wide class of three-dimensional gravity models can be put into
"Chern-Simons-like" form. We perform a Hamiltonian analysis of the general
model and then specialise to Einstein-Cartan Gravity, General Massive Gravity,
the recently proposed Zwei-Dreibein Gravity and a further parity violating
generalisation combining the latter two.


title:
Exotic magnetic order in the orbital-selective Mott regime of
  multiorbital systems

abstract:
  The orbital-selective Mott phase (OSMP) of multiorbital Hubbard models has
been extensively analyzed before using static and dynamical mean-field
approximations. In parallel, the properties of Block states
(antiferromagnetically coupled ferromagnetic spin clusters) in Fe-based
superconductors have also been much discussed. The present effort uses
numerically exact techniques in one-dimensional systems to report the
observation of Block states within the OSMP regime, connecting two seemingly
independent areas of research, and providing analogies with the physics of
Double-Exchange models.


title: Heliostat blocking and shadowing efficiency in the video-game era

abstract:
  Blocking and shadowing is one of the key effects in designing and evaluating
a thermal central receiver solar tower plant. Therefore it is convenient to
develop efficient algorithms to compute the area of an heliostat blocked or
shadowed by the rest of the field. In this paper we explore the possibility of
using very efficient clipping algorithms developed for the video game and
imaging industry to compute the blocking and shadowing efficiency of a solar
thermal plant layout. We propose an algorithm valid for arbitrary position,
orientation and size of the heliostats. This algorithm turns out to be very
accurate, free of assumptions and fast. We show the feasibility of the use of
this algorithm to the optimization of a solar plant by studying a couple of
examples in detail.


title:
Relativistic surfatron process for Landau resonant electrons in
  radiation belts

abstract:
  Recent theoretical studies of the nonlinear wave-particle interactions for
relativistic particles have shown that Landau resonant orbits could be
efficiently accelerated along the mean background magnetic field for
propagation angles $\theta$ in close proximity to a critical propagation
$\theta_\textrm{c}$ associated with a Hopf--Hopf bifurcation condition. In this
report, we extend previous studies to reach greater modeling capacities for the
study of electrons in radiation belts by including longitudinal wave effects
and inhomogeneous magnetic fields. We find that even though both effects can
limit the surfatron acceleration of electrons in radiation belts, gains in
energy of the order of 100 keV, taking place on the order of ten milliseconds,
are sufficiently strong for the mechanism to be relevant to radiation belt
dynamics.


title:
Bounded solutions of finite lifetime to differential equations in Banach
  spaces

abstract:
  Consider a smooth vector field $f\colon \mathbb{R}^n\to\mathbb{R}^n$ and a
maximal solution $\gamma\colon \,]a,b[\,\to \mathbb{R}^n$ to the ordinary
differential equation $x'=f(x)$. It is a well-known fact that, if $\gamma$ is
bounded, then $\gamma$ is a global solution, i.e., $\,]a,b[\,=\mathbb{R}$. We
show by example that this conclusion becomes invalid if $\mathbb{R}^n$ is
replaced with an infinite-dimensional Banach space.


title: Real Time Industrial Monitoring System

abstract:
  Industries are the biggest workplace all over the world, also there are large
number of peoples involves as a worker and most of them are work as a machine
operator. There are many systems developed for industrial work place, some of
them, monitors machine processes and some do monitoring and control of machine
parameters. Such as speed, temperature, production batch count etc. However
there is no such system available that provides monitoring of operator during
their work is in progress at workplace. This paper proposes the monitoring of
the operators and the machines, by Real time Operator -Machine Allocation and
monitoring system (Omams). Omams allocates a work machine to worker at entry
point itself. It uses automation with RFID and one of the standards of wireless
communication method. The system can be industry specific. Through this
research paper our approach is to make fair allocation of machine to the
operator in industry and reduce hassle for efficiency calculations.


title:
Accelerating Asymptotically Exact MCMC for Computationally Intensive
  Models via Local Approximations

abstract:
  We construct a new framework for accelerating Markov chain Monte Carlo in
posterior sampling problems where standard methods are limited by the
computational cost of the likelihood, or of numerical models embedded therein.
Our approach introduces local approximations of these models into the
Metropolis-Hastings kernel, borrowing ideas from deterministic approximation
theory, optimization, and experimental design. Previous efforts at integrating
approximate models into inference typically sacrifice either the sampler's
exactness or efficiency; our work seeks to address these limitations by
exploiting useful convergence characteristics of local approximations. We prove
the ergodicity of our approximate Markov chain, showing that it samples
asymptotically from the \emph{exact} posterior distribution of interest. We
describe variations of the algorithm that employ either local polynomial
approximations or local Gaussian process regressors. Our theoretical results
reinforce the key observation underlying this paper: when the likelihood has
some \emph{local} regularity, the number of model evaluations per MCMC step can
be greatly reduced without biasing the Monte Carlo average. Numerical
experiments demonstrate multiple order-of-magnitude reductions in the number of
forward model evaluations used in representative ODE and PDE inference
problems, with both synthetic and real data.


title: Cooling antihydrogen ions for the free-fall experiment GBAR

abstract:
  We discuss an experimental approach allowing to prepare antihydrogen atoms
for the GBAR experiment. We study the feasibility of all necessary experimental
steps: The capture of incoming $\bar{\rm H}^+$ ions at keV energies in a deep
linear RF trap, sympathetic cooling by laser cooled Be$^+$ ions, transfer to a
miniaturized trap and Raman sideband cooling of an ion pair to the motional
ground state, and further reducing the momentum of the wavepacket by adiabatic
opening of the trap. For each step, we point out the experimental challenges
and discuss the efficiency and characteristic times, showing that capture and
cooling are possible within a few seconds.


title:
Effective dynamics of a tracer particle in a dense homogeneous quantum
  gas

abstract:
  We investigate the mean field regime of the dynamics of a tracer particle in
a homogenous quantum gas. For a bosonic gas, we show that this regime is
constrained by the well known requirement of an appropriate mean field scaling
of the interaction. For fermions, however, we find an important qualitative
difference. Not only are fermions much more homogeneously distributed than
bosons but also deviations from the mean are due only to fast degrees of
freedom in the gas. This observation leads to an explanation of why a tracer
particle behaves freely in the dense homogeneous fermion gas despite of a
non-scaled interaction, i.e., despite of non-vanishing statistical
fluctuations. Finally, we indicate how the gained insight can be rigorously
justified.


title: Geodesic Density Tracking with Applications to Data Driven Modeling

abstract:
  Many problems in dynamic data driven modeling deals with distributed rather
than lumped observations. In this paper, we show that the Monge-Kantorovich
optimal transport theory provides a unifying framework to tackle such problems
in the systems-control parlance. Specifically, given distributional
measurements at arbitrary instances of measurement availability, we show how to
derive dynamical systems that interpolate the observed distributions along the
geodesics. We demonstrate the framework in the context of three specific
problems: (i) \emph{finding a feedback control} to track observed ensembles
over finite-horizon, (ii) \emph{finding a model} whose prediction matches the
observed distributional data, and (iii) \emph{refining a baseline model} that
results a distribution-level prediction-observation mismatch. We emphasize how
the three problems can be posed as variants of the optimal transport problem,
but lead to different types of numerical methods depending on the problem
context. Several examples are given to elucidate the ideas.


title:
Hydrodynamic Limit of mean zero condensing Zero Range Processes with
  sub-critical initial profiles

abstract:
  We prove the hydrodynamic limit of mean zero condensing Zero Range Processes
with bounded local jump rate, for sub-critical initial profiles. The proof is
based on H.T. Yau's relative entropy method and is made possible by a
generalisation of the One Block Estimate.


title: A Representation Theorem for Second-Order Functionals

abstract:
  Representation theorems relate seemingly complex objects to concrete, more
tractable ones.
  In this paper, we take advantage of the abstraction power of category theory
and provide a general representation theorem for a wide class of second-order
functionals which are polymorphic over a class of functors. Types polymorphic
over a class of functors are easily representable in languages such as Haskell,
but are difficult to analyse and reason about. The concrete representation
provided by the theorem is easier to analyse, but it might not be as convenient
to implement. Therefore, depending on the task at hand, the change of
representation may prove valuable in one direction or the other.
  We showcase the usefulness of the representation theorem with a range of
examples. Concretely, we show how the representation theorem can be used to
show that traversable functors are finitary containers, how parameterised
coalgebras relate to very well-behaved lenses, and how algebraic effects might
be implemented in a functional language.


title: On the Prediction Performance of the Lasso

abstract:
  Although the Lasso has been extensively studied, the relationship between its
prediction performance and the correlations of the covariates is not fully
understood. In this paper, we give new insights into this relationship in the
context of multiple linear regression. We show, in particular, that the
incorporation of a simple correlation measure into the tuning parameter can
lead to a nearly optimal prediction performance of the Lasso even for highly
correlated covariates. However, we also reveal that for moderately correlated
covariates, the prediction performance of the Lasso can be mediocre
irrespective of the choice of the tuning parameter. We finally show that our
results also lead to near-optimal rates for the least-squares estimator with
total variation penalty.


title:
Tripartite separability conditions exponentially violated by Gaussian
  states

abstract:
  Starting with a set of conditions for bipartite separability of arbitrary
quantum states in any dimension and expressed in terms of arbitrary operators
whose commutator is a $c$-number, we derive a hierarchy of conditions for
tripartite separability of continuous-variable three-mode quantum states. These
conditions have the form of inequalities for higher-order moments of linear
combinations of the mode operators. They enable one to distinguish between all
possible kinds of tripartite separability, while the strongest violation of
these inequalities is a sufficient condition for genuine tripartite
entanglement. We construct Gaussian states for which the violation of our
conditions grows exponentially with the order of the moments of the mode
operators. By going beyond second moments, our conditions are expected to be
useful as well for the detection of tripartite entanglement of non-Gaussian
states.


title:
Wafer-scale solution-derived molecular gate dielectrics for low-voltage
  graphene electronics

abstract:
  Graphene field-effect transistors are integrated with solution-processed
multilayer hybrid organic-inorganic self-assembled nanodielectrics (SANDs). The
resulting devices exhibit low-operating voltage (2 V), negligible hysteresis,
current saturation with intrinsic gain > 1.0 in vacuum (pressure < 2 x 10-5
Torr), and overall improved performance compared to control devices on
conventional SiO2 gate dielectrics. Statistical analysis of the field-effect
mobility and residual carrier concentration demonstrate high spatial uniformity
of the dielectric interfacial properties and graphene transistor
characteristics over full 3 inch wafers. This work thus establishes SANDs as an
effective platform for large-area, high-performance graphene electronics.


title: Interpolation properties of generalized plane waves

abstract:
  This paper aims at developing new shape functions adapted to smooth vanishing
coefficients for scalar wave equation. It proposes the numerical analysis of
their interpolation properties. The interpolation is local but high order
convergence is shown with respect to the size of the domain considered. The new
basis functions are then implemented in a numerical method to solve a scalar
wave equation problem with a mixed boundary condition. The order of convergence
of the method varies linearly with the one of the interpolation.


title: Incompressible surfaces in rank one locally symmetric spaces

abstract:
  We show that cocompact lattices in rank one simple Lie groups of non-compact
type distinct from SO(2m,1) (m>0) contain surface subgroups.

Eighteen New Variable Stars in Cassiopeia and Variability Checking for
  NSV 364

abstract:
  I report the discovery of eighteen new variable stars in Cassiopeia: eight
pulsating (2MASS J00584964+5909260; GSC 03680-00667; GSC 03680-01320; GSC
03680-01488; 2MASS J02472793+6149024; GSC 04047-01118; GSC 04047-01418; GSC
04051-01789), six eclipsing (GSC 03680-00423; 2MASS J02443720+6143091; GSC
04047-00381; GSC 04047-00558; GSC 04051-02027; GSC 04051-02533), three rotating
(ALS 6430; 2MASS J01020513+5912394; GSC 04051-01669), and one eruptive (GSC
04051-02483). The suspected variable star NSV 364 was checked for variability
in six nights of observations and in the complete SuperWasp survey dataset: no
variability was detected.


title:
Blue light absorption enhancement based on vertically channelling modes
  in nano-holes arrays

abstract:
  We investigate the specific optical regime occurring at short wavelengths, in
the high absorption regime, in silicon thin-films patterned by periodically
arranged nano-holes. Near-field scanning optical microscopy indicates that the
incoming light is coupled to vertically channelling modes. Optical modelling
and simulations show that the light, travelling inside the low-index regions,
is absorbed at the direct vicinity of the nano-holes sidewalls. This
channelling regime should be taken into account for light management in
optoelectronic devices.


title: Atom Interferometry in Space: Thermal Management and Magnetic Shielding

abstract:
  Atom interferometry is an exciting tool to probe fundamental physics. It is
considered especially apt to test the universality of free fall by using two
different sorts of atoms. The increasing sensitivity required for this kind of
experiment sets severe requirements on its environments, instrument control,
and systematic effects. This can partially be mitigated by going to space as
was proposed, for example, in the Spacetime Explorer and Quantum Equivalence
Principle Space Test (STE-QUEST) mission. However, the requirements on the
instrument are still very challenging. For example, the specifications of the
STE-QUEST mission imply that the Feshbach coils of the atom interferometer are
allowed to change their radius only by about 260 nm or 2.6E-4% due to thermal
expansion although they consume an average power of 22 W. Also Earth's magnetic
field has to be suppressed by a factor of 10E5. We show in this article that
with the right design such thermal and magnetic requirements can indeed be met
and that these are not an impediment for the exciting physics possible with
atom interferometers in space.

Nine New Variable Stars in Cygnus and Variability Type Determination of
  [Wm2007] 1176

abstract:
  I report the discovery of nine new variable stars in Cygnus: five pulsating
(VSX J192319.8+280832, VSX J192405.8+280352, VSX J192220.7+275518, VSX
J192304.4+280231, VSX J192255.1+274744) and four eclipsing (VSX

J192524.9+275342). The variability type of the variable star [WM2007] 1176,
that was considered in literature a possible RRC, was found to be a W UMa
variable with an obvious O'Connell effect.


title: Towards quantum dot arrays of entangled photon emitters

abstract:
  We show that with a new family of pyramidal site-controlled InGaAsN quantum
dots it is possible to obtain areas containing as much as 15% of
polarization-entangled photon emitters - a major improvement if compared to the
small fraction achievable by other quantum dot systems. Entanglement is
attested by a two-photon polarization state density matrix and the parameters
obtained from it. Emitters showing fidelities up to 0.721+-0.043 were found.


title:
Asymptotic behavior of the quadratic variation of the sum of two Hermite
  processes of consecutive orders

abstract:
  Hermite processes are self--similar processes with stationary increments
which appear as limits of normalized sums of random variables with long range
dependence. The Hermite process of order $1$ is fractional Brownian motion and
the Hermite process of order $2$ is the Rosenblatt process. We consider here
the sum of two Hermite processes of order $q\geq 1$ and $q+1$ and of different
Hurst parameters. We then study its quadratic variations at different scales.
This is akin to a wavelet decomposition. We study both the cases where the
Hermite processes are dependent and where they are independent. In the
dependent case, we show that the quadratic variation, suitably normalized,
converges either to a normal or to a Rosenblatt distribution, whatever the
order of the original Hermite processes.


title: The Radio Continuum-Star Formation Rate Relation in WSRT SINGS Galaxies

abstract:
  We study the spatially resolved Radio Continuum-Star Formation Rate (RC-SFR)
relation using state-of-the-art star-formation (SF) tracers in a sample of 17
THINGS galaxies. We use hybrid Sigma_SFR maps (GALEX FUV plus Spitzer 24 mu),
RC maps at 22/18 cm from the WSRT SINGS survey, and H-alpha maps to correct for
thermal RC emission. We compare azimuthally averaged radial profiles of the RC
and FUV/MIR-based Sigma_SFR maps and study pixel-by-pixel correlations at fixed
linear scales of 1.2 and 0.7 kpc. The ratio of the integrated SFRs from the RC
emission to that of the FUV/MIR-based SF tracers is R_int = 0.78 +/- 0.38,
consistent with Condon's relation. We find a tight correlation between the
radial profiles of the radio and FUV/MIR-based Sigma_SFR for the entire extent
of the disk. The ratio R of the azimuthally averaged radio to FUV/MIR-based
Sigma_SFR agrees with the integrated ratio with only small quasi-random
fluctuations as function of radius. Pixel-by-pixel plots show a tight
correlation in log-log diagrams of radio to FUV/MIR-based Sigma_SFR, with a
typical standard deviation of a factor of two. Averaged over our sample we find
(Sigma_SFR)_RC ~ (Sigma_SFR)_hyb^{0.63+/-0.25} implying that data points with
high Sigma_SFR are relatively radio dim, whereas the reverse is true for low
Sigma_SFR. We interpret this as a result of spectral ageing of CRe, which is
supported by the radio spectral index: data points dominated by young CRe are
relatively radio dim, those dominated by old CRe are relatively radio bright.
The ratio of radio to FUV/MIR-based integrated SFR is independent of global
galaxy parameters, suggesting that we can use RC emission as a universal SF
tracer for galaxies, if we restrict ourselves to global or azimuthally averaged
measurements. A magnetic field-SFR relation, B ~ SFR_hyb^{0.30+/-0.02}, holding
both globally and locally, can explain our results. (abridged)


title:
A non-isothermal, non-equimolar transient kinetic model for gas-solid
  reactions

abstract:
  A numerical model is presented, designed to simulate the kinetic and thermal
behaviour of a porous pellet in which any gas-solid reaction is taking place.
Its novelty consists in the fact that it can deal with reactions whether they
are exothermic or endothermic, whether they are equimolar or not, whether they
are reversible or irreversible, and further reactions in the transient regime
and even the possible presence of inert gases and solids can be treated. The
numerical scheme is based on the finite volume method in an implicit
formulation, with a specific treatment of the thermal source term for strongly
exothermic reactions. The model was validated by comparison with analytical and
numerical solutions from the literature and was used to simulate the exothermic
reaction involved in the oxidation of zinc sulphide.


title:
Determination of subject-specific muscle fatigue rates under static
  fatiguing operations

abstract:
  Cumulative local muscle fatigue may lead to potential musculoskeletal
disorder (MSD) risks {\color{red}, and subject-specific muscle fatigability
needs to be considered to reduce potential MSD risks.} This study was conducted
to determine local muscle fatigue rate at shoulder joint level based on an
exponential function derived from a muscle fatigue model. Forty male subjects
participated in a fatiguing operation under a static posture with a range of
relative force levels (14% - 33%). Remaining maximum muscle strengths were
measured after different fatiguing sessions. The time course of strength
decline was fitted to the exponential function. Subject-specific fatigue rates
of shoulder joint moment strength were determined. Good correspondence
($R^2>0.8$) was found in the regression of the majority (35 out of 40
subjects). Substantial inter-individual variability in fatigue rate was found
and discussed.


title: A Boolean Algebraic Approach to Semiproper Iterations

abstract:
  These notes present a compact and self-contained approach to iterated forcing
with a particular emphasis on semiproper forcing. We tried to make our
presentation accessible to any scholar who has some familiarity with forcing
and boolean valued models and full details of all proofs are given.
  We focus our presentation using the boolean algebra language and defining an
iteration system as a directed and commutative system of complete and injective
homomorphisms between complete and atomless boolean algebras.
  It is well known that the boolean algebra approach to forcing and iterations
is fully equivalent to the standard one. While there are several monographs
where forcing is introduced by means of boolean valued models, to our knowledge
no detailed account of iterated forcing following a boolean algebraic approach
has yet appeared. We believe that this different approach is fruitful since the
richness of the algebraic language simplifies many calculations and
definitions, among which that of RCS-limits. Some of the advantages of this
approach have been already outlined by Donder and Fuchs in
http://arxiv.org/abs/math/9207204.
  The first part of these notes present the general framework needed to develop
the notion of limit of an iterated system of forcings in the boolean algebraic
language. The second part contains a proof of the main result of Shelah on
semiproper iterations, i.e. that RCS-limit of semiproper iterations are
semiproper.


title: Modelling a new, low CO2 emissions, hydrogen steelmaking process

abstract:
  In an effort to develop breakthrough technologies that enable drastic
reduction in CO2 emissions from steel industry (ULCOS project), the reduction
of iron ore by pure hydrogen in a direct reduction shaft furnace was
investigated. After experimental and modelling studies, a 2D, axisymmetrical
steady-state model called REDUCTOR was developed to simulate a counter-current
moving bed reactor in which hematite pellets are reduced by pure hydrogen. This
model is based on the numerical solution of the local mass, energy and momentum
balances of the gas and solid species by the finite volume method. A single
pellet sub-model was included in the global furnace model to simulate the
successive reactions (hematite->magnetite ->wustite->iron) involved in the
process, using the concept of additive reaction times. The different steps of
mass transfer and possible iron sintering at the grain scale were accounted
for. The kinetic parameters were derived from reduction experiments carried out
in a thermobalance furnace, at different conditions, using small hematite cubes
shaped from industrial pellets. Solid characterizations were also performed to
further understand the microstrutural evolution. First results have shown that
the use of hydrogen accelerates the reduction in comparison to CO reaction,
making it possible to design a hydrogen-operated shaft reactor quite smaller
than current MIDREX and HYL. Globally, the hydrogen steelmaking route based on
this new process is technically and environmentally attractive. CO2 emissions
would be reduced by more than 80%. Its future is linked to the emergence of the
hydrogen economy.


title: Multiple singular values of Hankel operators

abstract:
  The goal of this paper is to construct a nonlinear Fourier transformation on
the space of symbols of compact Hankel operators on the circle. This
transformation allows to solve a general inverse spectral problem involving
singular values of a compact Hankel operator, with arbitrary multiplicities.
The formulation of this result requires the introduction of the pair made with
a Hankel operator and its shifted Hankel operator. As an application, we prove
that the space of symbols of compact Hankel operators on the circle admits a
singular foliation made of tori of finite or infinite dimensions, on which the
flow of the cubic Szeg\"o equation acts. In particular, we infer that arbitrary
solutions of the cubic Szeg\"o equation on the circle with finite momentum are
almost periodic with values in H^{1/2}(S ^1).


title:
Invariant differential operators on H-type groups and discrete
  components in restrictions of complementary series of rank one semisimple
  groups

abstract:
  We explicitly construct a finite number of discrete components in the
restriction of complementary series representations of rank one semisimple
groups $G$ to rank one subgroups $G_1$. For this we use the realizations of
complementary series representations of $G$ and $G_1$ on Sobolev spaces on the
nilpotent radicals $N$ and $N_1$ of the minimal parabolics in $G$ and $G_1$,
respectively. The groups $N$ and $N_1$ are of H-type and we construct
explicitly invariant differential operators between $N$ and $N_1$. These
operators induce the projections onto the discrete components. Our construction
of the invariant differential operators is carried out uniformly in the
framework of H-type groups and also works for those H-type groups which do not
occur as nilpotent radical of a parabolic subgroup in a semisimple group.

On Subversive Miner Strategies and Block Withholding Attack in Bitcoin
  Digital Currency

abstract:
  Bitcoin is a "crypto currency", a decentralized electronic payment scheme
based on cryptography. Bitcoin economy grows at an incredibly fast rate and is
now worth some 10 billions of dollars. Bitcoin mining is an activity which
consists of creating (minting) the new coins which are later put into
circulation. Miners spend electricity on solving cryptographic puzzles and they
are also gatekeepers which validate bitcoin transactions of other people.
Miners are expected to be honest and have some incentives to behave well.
However. In this paper we look at the miner strategies with particular
attention paid to subversive and dishonest strategies or those which could put
bitcoin and its reputation in danger. We study in details several recent
attacks in which dishonest miners obtain a higher reward than their relative
contribution to the network. In particular we revisit the concept of block
withholding attacks and propose a new concrete and practical block withholding
attack which we show to maximize the advantage gained by rogue miners.
  RECENT EVENTS: it seems that the attack was recently executed, see Section
XI-A.

Analysis of a mosquito-borne epidemic model with vector stages and
  saturating forces of infection

abstract:
  We study a mosquito-borne epidemic model where the vector population is
distinct in aquatic and adult stages and a saturating effect of disease
transmission is assumed to ocurr when the number of infectious (humans and
mosquitoes) becomes large enough. Several techniques, including center manifold
analysis and sensitivity analysis, have been used to reveal relevant features
of the model dynamics. We determine the existence of stability-instability
thresholds and the individual role played in such thresholds by the model
parameters.


title:
Performance of Hull-Detection Algorithms For Proton Computed Tomography
  Reconstruction

abstract:
  Proton computed tomography (pCT) is a novel imaging modality developed for
patients receiving proton radiation therapy. The purpose of this work was to
investigate hull-detection algorithms used for preconditioning of the large and
sparse linear system of equations that needs to be solved for pCT image
reconstruction. The hull-detection algorithms investigated here included
silhouette/space carving (SC), modified silhouette/space carving (MSC), and
space modeling (SM). Each was compared to the cone-beam version of filtered
backprojection (FBP) used for hull-detection. Data for testing these algorithms
included simulated data sets of a digital head phantom and an experimental data
set of a pediatric head phantom obtained with a pCT scanner prototype at Loma
Linda University Medical Center. SC was the fastest algorithm, exceeding the
speed of FBP by more than 100 times. FBP was most sensitive to the presence of
noise. Ongoing work will focus on optimizing threshold parameters in order to
define a fast and efficient method for hull-detection in pCT image
reconstruction.


title: Dynamics and energetics of emergent magnetic monopoles in chiral magnets

abstract:
  The formation and destruction of topologically quantized magnetic whirls,
so-called skyrmions, in chiral magnets is driven by the creation and motion of
singular hedgehog defects. These can be identified with emergent magnetic
monopoles and antimonopoles. We investigate how the energetics of and forces
between monopoles and antimonopoles influence their creation rate and dynamics.
We study a single skyrmion line defect in the helical phase using both
micromagnetic simulations and a Ginzburg-Landau analysis. Monopole-antimonople
pairs are created in a thermally activated process, largely controlled by the
(core) energy of the monopole. The force between monopoles and antimonopoles is
linear in distance and described by a string tension. The sign and size of the
string tension determines the stability of the phases and the velocity of the
monopoles.


title:
A Quantum Field Approach for Advancing Optical Coherence Tomography Part
  I: First Order Correlations, Single Photon Interference, And Quantum Noise

abstract:
  Optical coherence tomography has become an important imaging technology in
cardiology and ophthalmology, with other applications under investigations.
Major advances in optical coherence tomography (OCT) imaging are likely to
occur through a quantum field approach to the technology. In this paper, which
is the first part in a series on the topic, the quantum basis of OCT first
order correlations is expressed in terms of full field quantization.
Specifically first order correlations are treated as the linear sum of single
photon interferences along indistinguishable paths. Photons and the
electromagnetic (EM) field are described in terms of quantum harmonic
oscillators. While the author feels the study of quantum second order
correlations will lead to greater paradigm shifts in the field, addressed in
part II, advances from the study of quantum first order correlations are given.
In particular, ranging errors are discussed (with remedies) from vacuum
fluctuations through the detector port, photon counting errors, and position
probability amplitude uncertainty. In addition, the principles of quantum field
theory and first order correlations are needed for studying second order
correlations in part II.


title: AMS-02 and Next-to-Minimal Universal Extra Dimensions

abstract:
  The anomaly detected by AMS-02 and PAMELA in the cosmic-ray positron flux
when interpreted as arising from dark matter annihilation suggests that dark
matter may interact differently with hadrons and leptons so as to remain
compatible with cosmic-ray antiproton data. Such a scenario is readily
accommodated in models with extra spatial dimensions. We study indirect
detection of Kaluza-Klein (KK) dark matter in Universal Extra Dimensions with
brane-localized terms and fermion bulk masses: Next-to-Minimal Universal Extra
Dimensions. So that an excess of antiprotons is not produced in explaining the
positron anomaly, it is necessary that the KK bulk masses in the lepton and
hadron sectors be distinct. Even so, we find that cosmic-ray data disfavor a
heavy KK photon dark matter scenario. Also, we find these scenarios with
flavor-universal bulk masses to be in conflict with dijet and dilepton searches
at the LHC.

Quick Detection of Contaminants Leaching from Polypropylene Centrifuge
  Tube with Surface Enhanced Raman Spectroscopy and Ultra Violet Absorption
  Spectroscopy

abstract:
  Anomalous surface enhanced Raman scattering (SERS) peaks are identified for
liquid sample stored in polypropylene centrifuge tubes (PP tube) for months. We
observed the unexpected Raman peaks during experiments for Thiamine
Hydrochloride aqueous solution stored in PP tube for two months. In order to
identify the contaminants we have performed SERS experiments for de-ionized
water (DI water) stored in polypropylene centrifuge tube for two months and
compared them with fresh DI water sample. We have also carried out Ultra Violet
(UV) absorption spectra for both fresh and contaminated water. We believe that
the water is contaminated because of chemicals leaching from the PP tube. From
the GC-MS data the main contaminant was found to be Phthalic acid and its
derivatives. Further SERS and UV absorption experiment for Phthalic acid
correlates well with the anomalous peaks identified earlier. We qualitatively
confirmed the identification and quantitatively estimated the concentration of
suspect contaminants as between 1uM and 10uM with both SERS and UV absorption
spectroscopy. With UV absorption spectroscopy, we precisely estimate the
concentration as 2.1uM. We have shown that sample in PP tube can be
contaminated due to leaching chemicals upon long term storage and suggested
SERS and UV-absorption spectroscopy as two quick and simple techniques to
detect the contamination

Holomorphic Bundles and the Moduli Space of N=1 Supersymmetric Heterotic
  Compactifications

abstract:
  We describe the first order moduli space of heterotic string theory
compactifications which preserve $N=1$ supersymmetry in four dimensions, that
is, the infinitesimal parameter space of the Strominger system. We establish
that if we promote a connection on $TX$ to a field, the moduli space
corresponds to deformations of a holomorphic structure $\bar D$ on a bundle
$\cal Q$. The bundle $\cal Q$ is constructed as an extension by the cotangent
bundle $T^*X$ of the bundle $E= {\rm End}(V) \oplus {\rm End}(TX) \oplus TX$
with an extension class $\cal H$ which precisely enforces the anomaly
cancelation condition. The deformations corresponding to the bundle $E$ are
simultaneous deformations of the holomorphic structures on the poly-stable
bundles $V$ and $TX$ together with those of the complex structure of $X$. We
discuss the fact that the "moduli" corresponding to ${\rm End}(TX)$ cannot be
physical, but are however needed in our mathematical structure to be able to
enforce the anomaly cancelation condition. In the Appendix we comment on the
choice of connection on $TX$ which has caused some confusion in the community
before. It has been shown by Ivanov and others that this connection should also
satisfy the instanton equations, and we give another proof of this fact.


title: For-all Sparse Recovery in Near-Optimal Time

abstract:
  An approximate sparse recovery system in $\ell_1$ norm consists of parameters
$k$, $\epsilon$, $N$, an $m$-by-$N$ measurement $\Phi$, and a recovery
algorithm, $\mathcal{R}$. Given a vector, $\mathbf{x}$, the system approximates
$x$ by $\widehat{\mathbf{x}} = \mathcal{R}(\Phi\mathbf{x})$, which must satisfy
$\|\widehat{\mathbf{x}}-\mathbf{x}\|_1 \leq
(1+\epsilon)\|\mathbf{x}-\mathbf{x}_k\|_1$. We consider the 'for all' model, in
which a single matrix $\Phi$, possibly 'constructed' non-explicitly using the
probabilistic method, is used for all signals $\mathbf{x}$. The best existing
sublinear algorithm by Porat and Strauss (SODA'12) uses $O(\epsilon^{-3}
k\log(N/k))$ measurements and runs in time $O(k^{1-\alpha}N^\alpha)$ for any
constant $\alpha > 0$.
  In this paper, we improve the number of measurements to $O(\epsilon^{-2} k
\log(N/k))$, matching the best existing upper bound (attained by super-linear
algorithms), and the runtime to $O(k^{1+\beta}\textrm{poly}(\log
N,1/\epsilon))$, with a modest restriction that $\epsilon \leq (\log k/\log
N)^{\gamma}$, for any constants $\beta,\gamma > 0$. When $k\leq \log^c N$ for
some $c>0$, the runtime is reduced to $O(k\textrm{poly}(N,1/\epsilon))$. With
no restrictions on $\epsilon$, we have an approximation recovery system with $m
= O(k/\epsilon \log(N/k)((\log N/\log k)^\gamma + 1/\epsilon))$ measurements.


title: Liquid Metal Transformers

abstract:
  The room temperature liquid metal is quickly emerging as an important
functional material in a variety of areas like chip cooling, 3D printing or
printed electronics etc. With diverse capabilities in electrical, thermal and
flowing behaviors, such fluid owns many intriguing properties that had never
been anticipated before. Here, we show a group of unconventional phenomena
occurring on the liquid metal objects. Through applying electrical field on the
liquid metals immersed in water, a series of complex transformation behaviors
such as self-assembling of a sheet of liquid metal film into a single sphere,
quick mergences of separate metal droplets, controlled self-rotation and planar
locomotion of liquid metal objects can be realized. Meanwhile, it was also
found that two accompanying water vortexes were induced and reliably swirled
near the rotating liquid metal sphere. Further, effects of the shape, size,
voltage, orientation and geometries of the electrodes to control the liquid
metal transformers were clarified. Such events are hard to achieve otherwise on
rigid metal or conventional liquid spheres. This finding has both fundamental
and practical significances which suggest a generalized way of making smart
soft machine, collecting discrete metal fluids, as well as flexibly
manipulating liquid metal objects including accompanying devices.

Cross-phenotype meta-analysis reveals large-scale trans-eQTLs mediating
  patterns of transcriptional co-regulation

abstract:
  Genetic variation affecting gene regulation is a central driver of phenotypic
differences between individuals and can be used to uncover how biological
processes are organized in a cell. Although detecting cis-eQTLs is now routine,
trans-eQTLs have proven more challenging to find due to the modest variance
explained and the multiple tests burden of testing millions of SNPs for
association to thousands of transcripts. Here, we successfully map trans-eQTLs
with the complementary approach of looking for SNPs associated to the
expression of multiple genes simultaneously. We find 732 trans- eQTLs that
replicate across two continental populations; each trans-eQTL controls large
groups of target transcripts (regulons), which are part of interacting networks
controlled by transcription factors. We are thus able to uncover co-regulated
gene sets and begin describing the cell circuitry of gene regulation.


title: A Seeger-Sogge-Stein theorem for bilinear Fourier integral operators

abstract:
  We establish the regularity of bilinear Fourier integral operators with
bilinear amplitudes in $S^m_{1,0} (n,2)$ and non-degenerate phase functions,
from $L^p \times L^q \to L^r$ under the assumptions that $m\leq
-(n-1)(|\frac{1}{p}-\frac{1}{2}|+|\frac{1}{q}-\frac{1}{2}|)$ and
$\frac{1}{p}+\frac{1}{q}=\frac{1}{r}$. This is a bilinear version of the
classical theorem of Seeger-Sogge-Stein concerning the $L^p$ boundedness of
linear Fourier integral operators. Moreover, our result goes beyond the
aforementioned theorem in that it also includes the case of non-Banach target
spaces.

Surface plasmon enhanced broadband spectrophotometry on black silver
  substrates

abstract:
  We demonstrate surface plasmon-induced enhancements in optical imaging and
spectroscopy on silver coated silicon nanocones which we call black silver
substrate. The black silver substrate with dense and homogeneous nanocone
forest structure is fabricated on wafer level with a mass producible
nanomanufacturing method. The black silver substrate is able to efficiently
trap and convert incident photons into localized plasmons in a broad wavelength
range, which permits the enhancement in optical absorption from UV to NIR range
by 12 times, the visible fluorescence enhancement of ~30 times and the NIR
Raman scattering enhancement factor up to ~108. We show a considerable
potential of the black silver substrate in high sensitivity and broadband
optical sensing and imaging of chemical and biological molecules.

Exact Markovian SIR and SIS epidemics on networks and an upper bound for
  the epidemic threshold

abstract:
  Exploiting the power of the expectation operator and indicator (or Bernoulli)
random variables, we present the exact governing equations for both the SIR and
SIS epidemic models on \emph{networks}. Although SIR and SIS are basic epidemic
models, deductions from their exact stochastic equations \textbf{without}
making approximations (such as the common mean-field approximation) are scarce.
An exact analytic solution of the governing equations is highly unlikely to be
found (for any network) due to the appearing pair (and higher order)
correlations. Nevertheless, the maximum average fraction $y_{I}$ of infected
nodes in both SIS and SIR can be written as a quadratic form of the graph's
Laplacian. Only for regular graphs, the expression for the maximum of $y_{I}$
can be simplied to exhibit the explicit dependence on the spectral radius. From
our new Laplacian expression, we deduce a general \textbf{upper} bound for the
epidemic SIS threshold in any graph.


title: Dining Cryptographers with 0.924 Verifiable Collision Resolution

abstract:
  The dining cryptographers protocol implements a multiple access channel in
which senders and recipients are anonymous. A problem is that a malicious
participant can disrupt communication by deliberately creating collisions. We
propose a computationally secure dining cryptographers protocol with collision
resolution that achieves a maximum stable throughput of 0.924 messages per
round and which allows to easily detect disruptors.

Nanoreplicated positive and inverted sub-micron polymer pyramids array
  for surface enhanced Raman spectroscopy (SERS)

abstract:
  We demonstrate gold coated polymer surface enhanced Raman scattering (SERS)
substrates with a pair of complementary structures--positive and inverted
pyramids array structures fabricated by multiple-step molding and replication
process. The uniform SERS enhancement factors over the entire device surfaces
were measured as 7.2 X 10^4 for positive pyramids substrate while 1.6 X 10^6
for inverted pyramids substrate with Rhodamine 6G as the target analyte. Based
on the optical reflection measurement and FDTD simulation result, the
enhancement factor difference is attributed to plasmon resonance matching and
to SERS "hot spots ". With this simple, fast and versatile complementary
molding process, we can produce polymer SERS substrates with extremely low
cost, high throughput and high repeatability.


title:
When Data do not Bring Information: A Case Study in Markov Random Fields
  Estimation

abstract:
  The Potts model is frequently used to describe the behavior of image classes,
since it allows to incorporate contextual information linking neighboring
pixels in a simple way. Its isotropic version has only one real parameter beta,
known as smoothness parameter or inverse temperature, which regulates the
classes map homogeneity. The classes are unavailable, and estimating them is
central in important image processing procedures as, for instance, image
classification. Methods for estimating the classes which stem from a Bayesian
approach under the Potts model require to adequately specify a value for beta.
The estimation of such parameter can be efficiently made solving the Pseudo
Maximum likelihood (PML) equations in two different schemes, using the prior or
the posterior model. Having only radiometric data available, the first scheme
needs the computation of an initial segmentation, while the second uses both
the segmentation and the radiometric data to make the estimation. In this
paper, we compare these two PML estimators by computing the mean square error
(MSE), bias, and sensitivity to deviations from the hypothesis of the model. We
conclude that the use of extra data does not improve the accuracy of the PML,
moreover, under gross deviations from the model, this extra information
introduces unpredictable distortions and bias.


title: General Focus Point in the MSSM

abstract:
  The minimal supersymmetric extension of the Standard Model (SM) is a well
motivated scenario for physics beyond the SM, which allows a perturbative
description of the theory up to scales of the order of the Grand Unification
scale, where gauge couplings unify. The Higgs mass parameter is insensitive to
the ultraviolet physics and is only sensitive to the scale of soft
supersymmetry breaking parameters. Present collider bounds suggest that the
characteristic values of these parameters may be significantly larger than the
weak scale. Large values of the soft breaking parameters, however, induce large
radiative corrections to the Higgs mass parameter and therefore the proper
electroweak scale may only be obtained by a fine tuned cancellation between the
square of the holomorphic \mu-parameter and the Higgs supersymmetry breaking
square mass parameter. This can only be avoided if there is a correlation
between the scalar and gaugino mass parameters, such that the Higgs
supersymmetry breaking parameter remains of the order of the weak scale. The
scale at which this happens is dubbed as focus point. In this article, we
define the general conditions required for this to happen, for different values
of the messenger scale at which supersymmetry breaking is transmitted to the
observable sector, and for arbitrary boundary conditions of the sfermion,
gaugino, and Higgs mass parameters. Specific supersymmetry breaking scenarios
in which these correlations may occur are also discussed.

Flows in Complex Networks: Theory, Algorithms, and Application to
  Lennard-Jones Cluster Rearrangement

abstract:
  A set of analytical and computational tools based on transition path theory
(TPT) is proposed to analyze flows in complex networks. Specifically, TPT is
used to study the statistical properties of the reactive trajectories by which
transitions occur between specific groups of nodes on the network. Sampling
tools are built upon the outputs of TPT that allow to generate these reactive
trajectories directly, or even transition paths that travel from one group of
nodes to the other without making any detour and carry the same probability
current as the reactive trajectories. These objects permit to characterize the
mechanism of the transitions, for example by quantifying the width of the tubes
by which these transitions occur, the location and distribution of their
dynamical bottlenecks, etc. These tools are applied to a network modeling the
dynamics of the Lennard-Jones cluster with 38 atoms (LJ38) and used to
understand the mechanism by which this cluster rearranges itself between its
two most likely states at various temperatures.

Lithography-free sub-100nm nanocone array antireflection layer for
  low-cost silicon solar cell

abstract:
  High density and uniformity sub-100nm surface oxidized silicon nanocone
forest structure is created and integrated onto the existing texturization
microstructures on photovoltaic device surface by a one-step high throughput
plasma enhanced texturization method. We suppressed the broadband optical
reflection on chemically textured grade-B silicon solar cells for up to 70.25%
through this nanomanufacturing method. The performance of the solar cell is
improved with the short circuit current increased by 7.1%, fill factor
increased by 7.0%, conversion efficiency increased by 14.66%. Our method
demonstrates the potential to improve the photovoltaic device performance with
low cost high and throughput nanomanufacturing technology.


title:
Quantum criticality of quasi one-dimensional topological Anderson
  insulators

abstract:
  We present an analytic theory of quantum criticality in the quasi
one-dimensional topological Anderson insulators of class AIII and BDI. We
describe the systems in terms of two parameters $(g,\chi)$ representing
localization and topological properties, respectively. Surfaces of half-integer
valued $\chi$ define phase boundaries between distinct topological sectors.
Upon increasing system size, the two parameters exhibit flow similar to the
celebrated two parameter flow describing the class A quantum Hall insulator.
However, unlike the quantum Hall system, an exact analytical description of the
entire phase diagram can be given. We check the quantitative validity of our
theory by comparison to numerical transfer matrix computations.

Monolithic Integrations of Slanted Silicon Nanostructures on 3D
  Microstructures and Their Application to Surface Enhanced Raman Spectroscopy

abstract:
  We demonstrated fabrication of black silicon with slanted nanocone array on
both planar and 3D micro and meso scale structures produced by a
high-throughput lithography-free oblique-angle plasma etching process.
Nanocones with gradual change in height were created on the same piece of
silicon. The relation between the slanted angle of nanocones and incident angle
of directional plasma is experimentally investigated. In order to demonstrate
the monolithic integration of nanostructures on micro and meso scale non-planar
surfaces, nanocone forest is fabricated on non-planar silicon surfaces in
various morphologies such as silicon atomic force microscopy (AFM) tips and
pyramidal pits. By integrating nanocones on inverse silicon micro-pyramid array
devices, we further improved the surface enhanced Raman scattering (SERS)
enhancement property of this optimized commercial SERS substrate by several
folds even when using 66% less noble metal coating. We investigated the length
gradient dependence and asymmetric properties of SERS effects for slanted
nanocone with polarized excitation. This versatile and angle-controllable
nanocone fabrication and monolithic 3D nano-micro-meso integration method
provides new dimensions for production and optimization of SERS and other
nanophotonic sensors.


title:
Analysis of Aggregated Functional Data from Mixed Populations with
  Application to Energy Consumption

abstract:
  Understanding the energy consumption patterns of different types of consumers
is essential in any planning of energy distribution. However, obtaining
consumption information for single individuals is often either not possible or
too expensive. Therefore, we consider data from aggregations of energy use,
that is, from sums of individuals' energy use, where each individual falls into
one of C consumer classes. Unfortunately, the exact number of individuals of
each class may be unknown: consumers do not always report the appropriate
class, due to various factors including differential energy rates for different
consumer classes. We develop a methodology to estimate the expected energy use
of each class as a function of time and the true number of consumers in each
class. We also provide some measure of uncertainty of the resulting estimates.
To accomplish this, we assume that the expected consumption is a function of
time that can be well approximated by a linear combination of B-splines.
Individual consumer perturbations from this baseline are modeled as B-splines
with random coefficients. We treat the reported numbers of consumers in each
category as random variables with distribution depending on the true number of
consumers in each class and on the probabilities of a consumer in one class
reporting as another class. We obtain maximum likelihood estimates of all
parameters via a maximization algorithm. We introduce a special numerical trick
for calculating the maximum likelihood estimates of the true number of
consumers in each class. We apply our method to a data set and study our method
via simulation.

Elastomeric 2D Grating and Hemispherical Optofluidic Chamber for
  Multifunctional Fluidic Sensing

abstract:
  We present an optofluidic sensor based on an elastomeric two-dimensional (2D)
grating integrated inside a hemispherical fluid chamber. Laser beam is
diffracted before (reflection) and after (transmission) going through the
grating and liquid in the dome chamber. The sensing mechanism is investigated
and simulated with a finite difference time domain (FDTD) based electromagnetic
(EM) method. For experiment, by analyzing the size, power and shape of the 2D
diffraction patterns, we can retrieve multiple parameters of the liquid
including the refractive index, pressure and opacity with high sensitivity. We
demonstrate that glucose concentration can be monitored when mixed in different
concentrated phosphate buffered saline (PBS) solution. The free-solution
binding of bovine serum albumin (BSA) and anti-BSA IgG is detected with this
optical sensor. This low-cost, multifunctional and reliable optofluidic sensor
has the potential to be used as monitor of biofluid such as blood in
hemodialysis.


title: Transition probabilities in the $U(3,3)$ limit of the symplectic IVBM

abstract:
  The tensor properties of the algebra generators are determined in respect to
the reduction chain $Sp(12,R) \supset U(3,3) \supset U_{p}(3) \otimes
\overline{U_{n}(3)}\supset U^{\ast}(3) \supset O(3)$, which defines one of the
dynamical symmetry limits of the Interacting Vector Boson Model (IVBM). The
symplectic basis according to the considered chain is thus constructed and the
action of the $Sp(12,R)$ generators as transition operators between the basis
states is illustrated. The matrix elements of the $U(3,3)$ ladder operators in
the so obtained symmetry-adapted basis are given. The $U(3,3)$ limit of the
model is further tested on the more complicated and complex problem of
reproducing the $B(E2)$ transition probabilities between the collective states
of the ground band in $^{104}Ru$, $^{192}Os$, $^{192}Pt$, and $^{194}Pt$
isotopes, considered by many authors to be axially asymmetric. Additionally,
the excitation energies of the ground and $\gamma$ bands in $^{104}Ru$ are
calculated. The theoretical predictions are compared with the experimental data
and some other collective models which accommodate the $\gamma-$rigid or
$\gamma-$soft structures. The obtained results reveal the applicability of the
model for the description of the collective properties of nuclei, exhibiting
axially asymmetric features.

Sub-nanometer flattening of a 45-cm long, 45-actuator x-ray deformable
  mirror

abstract:
  We have built a 45-cm long x-ray deformable mirror of super-polished
single-crystal silicon that has 45 actuators along the tangential axis. After
assembly the surface height error was 19 nm rms. With use of high-precision
visible-light metrology and precise control algorithms, we have actuated the
x-ray deformable mirror and flattened its entire surface to 0.7 nm rms
controllable figure error. This is, to our knowledge, the first sub-nanometer
active flattening of a substrate longer than 15 cm.

Evolution of the magnetization after a local quench in the critical
  transverse-field Ising chain

abstract:
  We study the time evolution of the local magnetization in the critical Ising
chain in a transverse field after a sudden change of the parameters at a
defect. The relaxation of the defect magnetization is algebraic and the
corresponding exponent, which is a continuous function of the defect
parameters, is calculated exactly. In finite chains the relaxation is
oscillating in time and its form is conjectured on the basis of precise
numerical calculations.


title: Balance equations in semi-relativistic quantum hydrodynamics

abstract:
  Method of the quantum hydrodynamics has been applied in quantum plasmas
studies. As the first step in our consideration, derivation of classical
semi-relativistic (i. e. described by the Darwin Lagrangian on microscopic
level) hydrodynamical equations is given after a brief review of method
development. It provides better distinguishing between classic and quantum
semi-relativistic effects. Derivation of the classical equations is interesting
since it is made by a natural, but not very widespread method. This derivation
contains explicit averaging of the microscopic dynamics. Derivation of
corresponding quantum hydrodynamic equations is presented further. Equations
are obtained in the five-momentum approximation including the continuity
equation, Euler and energy balance equations. It is shown that relativistic
corrections lead to presence of new quantum terms in expressions for a force
field, a work field etc. The semi-relativistic generalization of the quantum
Bohm potential is obtained. Quantum part of the energy current, which is an
analog of the quantum Bohm potential for the energy evolution equation, is
derived. The Langmuir wave dispersion in semi-relativistic quantum plasmas,
corresponding to the Darwin Lagrangian, is also considered to demonstrate
contribution of semi-relativistic effects on basic plasma phenomenon.


title:
Adaptive and model-based control theory applied to convectively unstable
  flows

abstract:
  Research on active control for the delay of laminar-turbulent transition in
boundary layers has made a significant progress in the last two decades, but
the employed strategies have been many and dispersed. Using one framework, we
review model-based techniques, such as linear-quadratic regulators, and
model-free adaptive methods, such as least-mean square filters. The former are
supported by a elegant and powerful theoretical basis, whereas the latter may
provide a more practical approach in the presence of complex disturbance
environments, that are difficult to model. We compare the methods with a
particular focus on efficiency, practicability and robustness to uncertainties.
Each step is exemplified on the one-dimensional linearized Kuramoto-Sivashinsky
equation, that shows many similarities with the initial linear stages of the
transition process of the flow over a flat plate. Also, the source code for the
examples are provided.

Open-beauty production in $p$Pb collisions at $\sqrt{s_{NN}}$=5 TeV:
  effect of the gluon nuclear densities

abstract:
  We present our results on open beauty production in proton-nucleus collisions
for the recent LHC $p$Pb run at $\sqrt{s_{NN}}$=5 TeV. We have analysed the
effect of the modification of the gluon PDFs in nucleus at the level of the
nuclear modification factor. Because of the absence of measurement in $pp$
collisions at the same energy, we also propose the study of the
forward-to-backward yield ratio in which the unknown proton-proton yield
cancel. Our results are compared with the data obtained by LHCb collaboration
and show a good agreement.


title: Two-point functions and their applications in geometry

abstract:
  The maximum principle is one of the most important tools in the analysis of
geometric partial differential equations. Traditionally, the maximum principle
is applied to a scalar function defined on a manifold, but in recent years more
sophisticated versions have emerged. One particularly interesting direction
involves applying the maximum principle to functions that depend on a pair of
points. This technique is particularly effective in the study of problems
involving embedded surfaces.
  In this survey, we first describe some foundational results on curve
shortening flow and mean curvature flow. We then describe Huisken's work on the
curve shortening flow where the method of two-point functions was introduced.
Finally, we discuss several recent applications of that technique. These
include sharp estimates for mean curvature flow, as well as the proof of
Lawson's 1970 conjecture concerning minimal tori in S^3.


title: Cosmological model with variable vacuum pressure

abstract:
  Scenarios of cosmological evolution having inflationary stages are studied by
using equations of state (EoS) inspired by the quark bag model. A crucial point
is the existence of states where the specific enthalpy of the cosmological
fluid vanishes. A large class of barotropic EoS admits, depending upon initial
conditions, for a concrete equation of state, analogs of the "Big Rip" as well
as solutions describing an exponential inflation followed by the usual matter
dominance. We found scalar field potentials that mimic the behavior of the
cosmological scale factor in case of special EoS from the above class.
Extensions to more general two-parametric EoS are discussed that describe a
pre-inflationary evolution.


title: Explicit Mapping of Acoustic Regimes For Wind Instruments

abstract:
  This paper proposes a methodology to map the various acoustic regimes of wind
instruments. The maps can be generated in a multi-dimensional space consisting
of design, control parameters, and initial conditions. The bound- aries of the
maps are obtained explicitly in terms of the parameters using a support vector
machine (SVM) classifier as well as a dedicated adaptive sam- pling scheme. The
approach is demonstrated on a simplified clarinet model for which several maps
are generated based on different criteria. Examples of computation of the
probability of occurrence of a specific acoustic regime are also provided. In
addition, the approach is demonstrated on a design optimization example for
optimal intonation.
