Dipole-dipole scattering in CGC/saturation approach at high energy:
  summing Pomeron loops

abstract:
  In this paper we demonstrate that the dense system of partons (gluons) can be
produced in dilute-dilute system scattering, using the example of dipole-dipole
collisions. This increase in density stems from the intensive gluon cascades
that can be described by the enhanced BFKL Pomeron diagrams (Pomeron loops).
For the first time we found the analytical solution to the equation for
diffraction production in the dipole-dense parton system scattering, using the
simplified BFKL kernel. Having this solution as well as the solution to
Balitsky- Kovchegov equation we developed technique that allowed us to
calculate the total cross section, cross sections for single and double
diffractions in the MPSI approximation. Calculating inclusive production and
two gluon correlations we see that the dense and strongly correlated system of
gluons can be produced at high energy in the dipole-dipole scattering.


title: Delay Optimal Scheduling for Energy Harvesting Based Communications

abstract:
  Green communication attracts increasing research interest recently. Equipped
with a rechargeable battery, a source node can harvest energy from ambient
environments and rely on this free and regenerative energy supply to transmit
packets. Due to the uncertainty of available energy from harvesting, however,
intolerably large latency and packet loss could be induced, if the source
always waits for harvested energy. To overcome this problem, one Reliable
Energy Source (RES) can be resorted to for a prompt delivery of backlogged
packets. Naturally, there exists a tradeoff between the packet delivery delay
and power consumption from the RES. In this paper, we address the delay optimal
scheduling problem for a bursty communication link powered by a
capacity-limited battery storing harvested energy together with one RES. The
proposed scheduling scheme gives priority to the usage of harvested energy, and
resorts to the RES when necessary based on the data and energy queueing
processes, with an average power constraint from the RES. Through
twodimensional Markov chain modeling and linear programming formulation, we
derive the optimal threshold-based scheduling policy together with the
corresponding transmission parameters. Our study includes three exemplary cases
that capture some important relations between the data packet arrival process
and energy harvesting capability. Our theoretical analysis is corroborated by
simulation results.


title: B0707-359: a case study of change in AGN-black hole spin axis

abstract:
  Structures of radio galaxies have the potential to reveal inconstancy in the
axis of the beams, which reflect the stability in the spin axis of the
supermassive black hole at the centre. We present radio observations of the
giant radio galaxy B0707-359 whose structure offers an interesting case study
of an AGN that may be exhibiting not only inconstancy in AGN output but also
inconstancy in direction of ejection axis. Its radio morphology shows evidence
for a restarting of the jets accompanied by an axis change. The observed
side-to-side asymmetries of this giant radio galaxy suggest that the new jets
are not in the plane of the sky. We infer that the hotspot advance velocities
are unusually large and of magnitude a few-tenths of the speed of light. The
dual-frequency radio images are consistent with a model where the beams from
the central engine ceased, creating a relic double radio source; this
interruption was accompanied by triggering of a movement of the axis of the
central engine at a rate of a few degrees Myr^-1. The closer location of the
giant radio galaxy axis to the host minor axis rather than the host major axis
is supportive of the restarting and axis-change model for the formation of the
double-double structure rather than the backflow model.


title: Unconditionality of orthogonal spline systems in $L^p$

abstract:
  Given any natural number $k$ and any dense point sequence $(t_n)$, we prove
that the corresponding orthonormal spline system of order $k$ is an
unconditional basis in reflexive $L^p$.

Electronic properties of delta-doped phosphorus layers in silicon and
  germanium

abstract:
  The Thomas-Fermi-Dirac (TFD) approximation and an sp3d5s* tight binding
method were used to calculate the electronic properties of a delta-doped
phosphorus layer in silicon. This self-consistent model improves on the
computational efficiency of "more rigorous" empirical tight binding and ab
initio density functional theory models without sacrificing the accuracy of
these methods. The computational efficiency of the TFD model provides improved
scalability for large multi-atom simulations, such as of nanoelectronic devices
that have experimental interest. We also present the first theoretically
calculated electronic properties of a delta-doped phosphorus layer in germanium
as an application of this TFD model.


title:
Nonlinear stochastic differential games involving a major player and a
  large number of collectively acting minor agents

abstract:
  The purpose of this paper is to study 2-person zero-sum stochastic
differential games, in which one player is a major one and the other player is
a group of $N$ minor agents which are collectively playing, statistically
identical and have the same cost-functional. The game is studied in a weak
formulation; this means in particular, we can study it as a game of the type
"feedback control against feedback control". The payoff/cost functional is
defined through a controlled backward stochastic differential equation, for
which driving coefficient is assumed to satisfy strict concavity-convexity with
respect to the control parameters. This ensures the existence of saddle point
feedback controls for the game with $N$ minor agents. We study the limit
behavior of these saddle point controls and of the associated Hamiltonian, and
we characterize the limit of the saddle point controls as the unique saddle
point control of the limit mean-field stochastic differential game.


title:
Correlated continuous-time random walks: combining scale-invariance with
  long-range memory for spatial and temporal dynamics

abstract:
  Standard continuous time random walk (CTRW) models are renewal processes in
the sense that at each jump a new, independent pair of jump length and waiting
time are chosen. Globally, anomalous diffusion emerges through action of the
generalized central limit theorem leading to scale-free forms of the jump
length or waiting time distributions. Here we present a modified version of
recently proposed correlated CTRW processes, where we incorporate a power-law
correlated noise on the level of both jump length and waiting time dynamics. We
obtain a very general stochastic model, that encompasses key features of
several paradigmatic models of anomalous diffusion: discontinuous, scale-free
displacements as in Levy flights, scale-free waiting times as in subdiffusive
CTRWs, and the long-range temporal correlations of fractional Brownian motion
(FBM). We derive the exact solutions for the single-time probability density
functions and extract the scaling behaviours. Interestingly, we find that
different combinations of the model parameters lead to indistinguishable shapes
of the emerging probability density functions and identical scaling laws. Our
model will be useful to describe recent experimental single particle tracking
data, that feature a combination of CTRW and FBM properties.

Emission Height and Temperature Distribution of White-Light Emission
  Observed by Hinode/SOT from the 2012 January 27 X-class Solar Flare

abstract:
  White-light emissions were observed from an X1.7 class solar flare on 27
January 2012, using three continuum bands (red, green, and blue) of the Solar
Optical Telescope (SOT) onboard the Hinode satellite. This event occurred near
the solar limb, and so differences in locations of the various emissions are
consistent with differences in heights above the photosphere of the various
emission sources. Under this interpretation, our observations are consistent
with the white-light emissions occurring at the lowest levels of where the Ca
II H emission occurs. Moreover, the centers of the source regions of the red,
green, and blue wavelengths of the white-light emissions are significantly
displaced from each other, suggesting that those respective emissions are
emanating from progressively lower heights in the solar atmosphere. The
temperature distribution was also calculated from the white-light data, and we
found the lower-layer emission to have a higher temperature. This indicates
that high-energy particles penetrated down to near the photosphere, and
deposited heat into the ambient lower layers of the atmosphere.


title: $D^*\bar D^*$ molecule interpretation of $Z_c(4025)$

abstract:
  We have used QCD sum rules to study the newly observed charged state
$Z_c(4025)$ as a hidden-charm $D^*\bar D^*$ molecular state with the quantum
numbers $I^G(J^{P})=1^+(1^{+})$. Using a $D^*\bar D^*$ molecular interpolating
current, we have calculated the two-point correlation function and the spectral
density up to dimension eight at leading order in $\alpha_s$. The extracted
mass is $m_X=(4.04\pm0.24)$ GeV. This result is compatible with the observed
mass of $Z_c(4025)$ within the errors, which implies a possible molecule
interpretation of this new resonance. We also predict the mass of the
corresponding hidden-bottom $B^*\bar B^*$ molecular state:
$m_{Z_b}=(9.98\pm0.21)$ GeV.


title:
Electronic structures and optical properties of realistic transition
  metal dichalcogenide heterostructures from first principles

abstract:
  We calculate from first principles the electronic structure and optical
properties of a number of transition metal dichalcogenide (TMD) bilayer
heterostructures consisting of MoS2 layers sandwiched with WS2, MoSe2, MoTe2,
BN, or graphene sheets. Contrary to previous works, the systems are constructed
in such a way that the unstrained lattice constants of the constituent
incommensurate monolayers are retained. We find strong interaction between the
\Gamma-point states in all TMD/TMD heterostructures, which can lead to an
indirect gap. On the other hand, states near the K-point remain as in the
monolayers. When TMDs are paired with BN or graphene layers, the interaction
around \Gamma-point is negligible, and the electronic structure resembles that
of two independent monolayers. Calculations of optical properties of the
MoS2/WS2 system show that even when the valence and conduction band edges are
located in different layers, the mixing of optical transitions is minimal, and
the optical characteristics of the monolayers are largely retained in these
heterostructures. The intensity of interlayer transitions is found to be
negligibly small, a discouraging result for engineering the optical gap of TMDs
by heterostructuring.

Complex organic molecules in the interstellar medium: IRAM 30 m line
  survey of Sagittarius B2(N) and (M)

abstract:
  The discovery of amino acids in meteorites and the detection of glycine in
samples returned from a comet to Earth suggest that the interstellar chemistry
is capable of producing such complex organic molecules. Our goal is to
investigate the degree of chemical complexity that can be reached in the ISM.
We performed an unbiased, spectral line survey toward Sgr B2(N) and (M) with
the IRAM 30m telescope in the 3mm window. The spectra were analyzed with a
simple radiative transfer model that assumes LTE but takes optical depth
effects into account. About 3675 and 945 spectral lines with a peak
signal-to-noise ratio higher than 4 are detected toward N and M, i.e. about 102
and 26 lines per GHz, respectively. This represents an increase by about a
factor of 2 over previous surveys of Sgr B2. About 70% and 47% of the lines
detected toward N and M are identified and assigned to 56 and 46 distinct
molecules as well as to 66 and 54 less abundant isotopologues of these
molecules, respectively. We also report the detection of transitions from 59
and 24 catalog entries corresponding to vibrationally or torsionally excited
states of some of these molecules, respectively. Excitation temperatures and
column densities were derived for each species but should be used with caution.
Among the detected molecules, aminoacetonitrile, n-propyl cyanide, and ethyl
formate were reported for the first time in space based on this survey, as were
5 rare isotopologues of vinyl cyanide, cyanoacetylene, and hydrogen cyanide. We
also report the detection of transitions from within 12 new vib. or tors.
excited states of known molecules. Although the large number of unidentified
lines may still allow future identification of new molecules, we expect most of
these lines to belong to vib. or tors. excited states or to rare isotopologues
of known molecules for which spectroscopic predictions are currently missing.

Suspicious Object Recognition Method in Video Stream Based on Visual
  Attention

abstract:
  We propose a state of the art method for intelligent object recognition and
video surveillance based on human visual attention. Bottom up and top down
attention are applied respectively in the process of acquiring interested
object(saliency map) and object recognition. The revision of 4 channel PFT
method is proposed for bottom up attention and enhances the speed and accuracy.
Inhibit of return (IOR) is applied in judging the sequence of saliency object
pop out. Euclidean distance of color distribution, object center coordinates
and speed are considered in judging whether the target is match and suspicious.
The extensive tests on videos and images show that our method in video analysis
has high accuracy and fast speed compared with traditional method. The method
can be applied into many fields such as video surveillance and security.

Analytical models of operational risk and new results on the correlation
  problem

abstract:
  We propose a portfolio approach for operational risk quantification based on
a class of analytical models from which we derive new results on the
correlation problem. In particular, we show that uniform correlation is a
robust assumption for measuring capital charges in these models.


title: Six problems in frame theory

abstract:
  We discuss various problems in frame theory that have been open for some
years. A short discussion of frame theory is also provided, but it only
contains the information that is necessary in order to understand the open
problems and their role.

Superconducting fiber with transition temperature up to 7.43 K in
  Nb2PdxS5-delta (0< x <0.6)

abstract:
  Wiring systems powered by high-efficient superconductors have long been a
dream of scientists, but researchers have faced practical challenges such as
finding flexible materials. Here we report superconductivity in Nb2PdxS5-delta
fibers with transition temperature up to 7.43 K, which have typical diameters
of 0.3-3 micrometer. Superconductivity occurs in a wide range of Pd and S
contents, suggesting that the superconductivity in this system is very robust.
Long fibers with suitable size provide a new route to high-power transmission
cables and electronic devices.

A review of the relevance of the 'CLOUD' results and other recent
  observations to the possible effect of cosmic rays on the terrestrial climate

abstract:
  The problem of the contribution of cosmic rays to climate change is a
continuing one and one of importance. In principle, at least, the recent
results from the CLOUD project at CERN provide information about the role of
ionizing particles in 'sensitizing' atmospheric aerosols which might, later,
give rise to cloud droplets. Our analysis shows that, although important in
cloud physics the results do not lead to the conclusion that cosmic rays affect
atmospheric clouds significantly, at least if H2SO4 is the dominant source of
aerosols in the atmosphere. An analysis of the very recent studies of
stratospheric aerosol changes following a giant solar energetic particles event
shows a similar negligible effect. Recent measurements of the cosmic ray
intensity show that a former decrease with time has been reversed. Thus, even
if cosmic rays enhanced cloud production, there will be a small global cooling,
not warming.

Hunting for Extremely Faint Planetary Nebulae in the SDSS Spectroscopic
  Database

abstract:
  Using ~1,700,000 target- and sky-fiber spectra from the SDSS, we have carried
out a systematic search for Galactic planetary nebulae (PNe) via detections of
the [OIII] 4959, 5007 lines. Thanks to the excellent sensitivity of the SDSS
spectroscopic surveys, this is by far the deepest search for PNe ever taken,
reaching a surface brightness of the [OIII] 5007 line down to about 29.0
mag./arcsec^2. The search recovers 13 previously known PNe in the Galactic
Caps. In total, 44 new PN candidates are identified, including 7 candidates of
multiple detections and 37 candidates of single detection. The 7 candidates of
multiple detections are all extremely large (between 21' - 154') and faint,
located mostly in the low Galactic latitude region and with a kinematics
similar to disk stars. After checking their images in Ha and other bands, three
of them are probably HII regions, one is probably associated with a new
supernova remnant, another one is possibly a true PN, and the remaining two
could be either PNe or supernova remnants. Based on sky positions and
kinematics, 7 candidates of single detection probably belong to the halo
population. If confirmed, they will increase the number of known PNe in the
Galactic halo significantly. All the newly identified PN candidates are very
faint, with a surface brightness of the [OIII] 5007 line between 27.0 - 30.0
mag./arcsec^2, very challenging to be discovered with previous techniques and
thus may greatly increase the number of "missing" faint PNe. Our results
demonstrate the power of large scale fiber spectroscopy in hunting for
ultra-faint PNe and other types of emission line nebulae. Combining the large
spectral databases provided by the SDSS and other on-going projects (e.g. the
LAMOST Galactic surveys), it is possible to build a statistically meaningful
sample of ultra-faint, large, evolved PNe, thus improving the census of
Galactic PNe.


title: Naturalness, Conformal Symmetry and Duality

abstract:
  We reconsider the naturalness from the viewpoint of effective field theories,
motivated by the alternative scenario that the standard model holds until a
high-energy scale such as the Planck scale. We propose a calculation scheme of
radiative corrections utilizing a hidden duality, in the expectation that the
unnaturalness for scalar masses might be an artifact in the effective theory
and it could be improved if features of an ultimate theory are taken in.


title:
Constraints on the radial distribution of the dust properties in the CQ
  Tau protoplanetary disk

abstract:
  Grain growth in protoplanetary disks is the first step towards the formation
of the rocky cores of planets. Models predict that grains grow, migrate, and
fragment in the disk and predict varying dust properties as a function of
radius, age, and physical properties. High-angular resolution observations at
more than one (sub-)mm wavelength are the essential tool for constraining grain
growth and migration on the disk midplane. We developed a procedure to analyze
self-consistently multi wavelength (sub-)mm continuum interferometric
observations of protoplanetary disks to constrain the radial distribution of
dust properties. We apply this technique to existing multi frequency continuum
mm observations of the disk around CQ Tau, a A8 pre-main sequence star with a
well-studied disk. We demonstrate that our models can be used to simultaneously
constrain the disk and dust structure. In CQ Tau, the best-fitting model has a
radial dependence of the maximum grain size, which decreases from a few cm in
the inner disk (<40 AU) to a few mm at 80 AU. Nevertheless, the currently
available dataset does not allow us to exclude the possibility of a uniform
grain size distribution at a 3sigma level.


title: Upscaling of dislocation walls in finite domains

abstract:
  We wish to understand the macroscopic plastic behaviour of metals by
upscaling the micro-mechanics of dislocations. We consider a highly simplified
dislocation network, which allows our microscopic model to be a one dimensional
particle system, in which the interactions between the particles (dislocation
walls) are singular and non-local.
  As a first step towards treating realistic geometries, we focus on
finite-size effects rather than considering an infinite domain as typically
discussed in the literature. We derive effective equations for the dislocation
density by means of \Gamma-convergence on the space of probability measures.
Our analysis yields a classification of macroscopic models, in which the size
of the domain plays a key role.


title: On the physical effects of consistent cosmological averaging

abstract:
  We use cosmological perturbation theory to study the backreaction effects of
a self-consistent and well-defined cosmological averaging on the dynamics and
the evolution of the Universe. Working with a perturbed
Friedman-Lemaitre-Robertson-Walker Einstein-de Sitter cosmological solution in
a comoving volume-preserving gauge, we compute the expressions for the
expansion scalar and deceleration parameter to second order, which we use to
characterize the backreaction. We find that the fractional shift in the Hubble
parameter with respect to the input background cosmological model is
Delta~10^{-5}, which leads to an effective energy density of the order of a few
times 10^{-5}. In addition, we find that an appropriate measure of the
fractional shift in the deceleration parameter Q is very large.


title: N-VSi-related center in non-irradiated 6H SiC nanostructure

abstract:
  We present the first findings of the vacancy-related centers identified by
the electron spin resonance (ESR) and electrically-detected (ED) ESR method in
the non-irradiated 6H-SiC nanostructure. This planar 6H-SiC nanostructure
represents the ultra-narrow p-type quantum well confined by the
{\delta}-barriers heavily doped with boron on the surface of the n-type 6H-SiC
(0001) wafer. The EDESR method by measuring the only magnetoresistance of the
6H SiC nanostructure under the high frequency generation from the
{\delta}-barriers appears to allow the identification of the silicon vacancy
centers as well as the triplet center with spin state S=1. The same triplet
center that is characterized by the larger value of the zero-field splitting
constant D and anisotropic g-factor is revealed by the ESR (X-band) method. The
hyperfine (hf) lines in the ESR and EDESR spectra originating from the hf
interaction with the 14N nucleus allow us to attribute this triplet center to
the N-VSi defect.


title: Weak contact equations for mappings into Heisenberg groups

abstract:
  Let k>n be positive integers. We consider mappings from a subset of
k-dimensional Euclidean space R^k to the Heisenberg group H^n with a variety of
metric properties, each of which imply that the mapping in question satisfies
some weak form of the contact equation arising from the sub-Riemannian
structure of the Heisenberg group. We illustrate a new geometric technique that
shows directly how the weak contact equation greatly restricts the behavior of
the mappings. In particular, we provide a new and elementary proof of the fact
that the Heisenberg group H^n is purely k-unrectifiable. We also prove that for
an open set U in R^k, the rank of the weak derivative of a weakly contact
mapping in the Sobolev space W^{1,1}_{loc}(U;R^{2n+1}) is bounded by $n$ almost
everywhere, answering a question of Magnani. Finally we prove that if a mapping
from U to H^n is s-H\"older continuous, s>1/2, and locally Lipschitz when
considered as a mapping into R^{2n+1}, then the mapping cannot be injective.
This result is related to a conjecture of Gromov.


title: Higgs Mass Bounds from Renormalization Flow for a simple Yukawa model

abstract:
  We study the functional renormalization group flow of a Higgs-Yukawa toy
model mimicking the top-Higgs sector of the standard model. This approach
allows for treating arbitrary bare couplings. For the class of standard bare
potentials of \phi^4-type at a given ultraviolet cut-off, we show that a finite
infrared Higgs mass range emerges naturally from the renormalization group flow
itself. Higgs masses outside the resulting bounds cannot be connected to any
conceivable set of bare parameters in this standard-model \phi^4 class. By
contrast, more general bare potentials allow to diminish the lower bound
considerably. We identify a simple renormalization group mechanism for this
depletion of the lower bound. If active also in the full standard model, Higgs
masses smaller than the conventional infrared window do not necessarily require
new physics at low scales or give rise to instability problems.


title: A Semidefinite Hierarchy for Containment of Spectrahedra

abstract:
  A spectrahedron is the positivity region of a linear matrix pencil and thus
the feasible set of a semidefinite program. We propose and study a hierarchy of
sufficient semidefinite conditions to certify the containment of a
spectrahedron in another one. This approach comes from applying a moment
relaxation to a suitable polynomial optimization formulation. The hierarchical
criterion is stronger than a solitary semidefinite criterion discussed earlier
by Helton, Klep, and McCullough as well as by the authors. Moreover, several
exactness results for the solitary criterion can be brought forward to the
hierarchical approach. The hierarchy also applies to the (equivalent) question
of checking whether a map between matrix (sub-)spaces is positive. In this
context, the solitary criterion checks whether the map is completely positive,
and thus our results provide a hierarchy between positivity and complete
positivity.


title:
Highlighting the mechanism of the quantum speedup by time-symmetric and
  relational quantum mechanics

abstract:
  Bob hides a ball in one of four drawers. Alice is to locate it. Classically
she has to open up to three drawers, quantally just one. The fundamental reason
for this quantum speedup is not known. The usual representation of the quantum
algorithm is limited to the process of solving the problem. We extend it to the
process of setting the problem. The number of the drawer with the ball becomes
a unitary transformation of the random outcome of the preparation measurement.
This extended, time-symmetric, representation brings in relational quantum
mechanics. It is with respect to Bob and any external observer and cannot be
with respect to Alice. It would tell her the number of the drawer with the ball
before she opens any drawer. To Alice, the projection of the quantum state due
to the preparation measurement should be retarded at the end of her search; in
the input state of the search, the drawer number is determined to Bob and
undetermined to Alice. We show that, mathematically, one can ascribe any part
of the selection of the random outcome of the preparation measurement to the
final Alice's measurement. Ascribing half of it explains the speedup of the
present algorithm. This projects the input state to Alice on a state of lower
entropy where she knows half of the number of the drawer with the ball in
advance. The quantum algorithm turns out to be a sum over histories in each of
which Alice knows in advance that the ball is in a pair of drawers and locates
it by opening one of the two. In the sample of quantum algorithms examined, the
part of the random outcome of the initial measurement selected by the final
measurement is one half or slightly above it. Conversely, given an oracle
problem, the assumption it is one half always corresponds to an existing
quantum algorithm and gives the order of magnitude of the number of oracle
queries required by the optimal one.


title: Negative-U Centers as a Basis of Topological Edge Channels

abstract:
  We present the findings of the studies of the silicon sandwich nanostructure
that represents the high mobility ultra - narrow silicon quantum well of the p
- type (Si - QW), 2 nm, confined by the delta - barriers, 3 nm, heavily doped
with boron on the n - type Si (100) surface. The ESR studies show that
nanostructured delta - barriers confining the Si - QW consist predominantly of
the dipole negative - U centers of boron, which are caused by the
reconstruction of the shallow boron acceptors along the <111> crystallographic
axis, 2B(0) = B(+) + B(-). The electrically ordered chains of dipole negative -
U centers of boron in the delta -barriers appear to give rise to the
topological edge states separated vertically, because the value of the
longitudinal, Gxx = 4e2/h, and transversal, Gxy = e2/h, conductance measured at
extremely low drain-source current indicates the exhibition of the Quantum Spin
Hall effect. Besides, the Aharonov - Casher conductance oscillations and the
0.7(2e2/h) - feature obtained are evidence of the interplay of the spontaneous
spin polarisation and the Rashba spin - orbit interaction that is attributable
to the formation of the topological edge channels. We discuss the
phenomenological model of the topological edge channel which can demonstrate
the ballistic, Aharonov - Chasher effect or Josephson junction behaviour in
dependence on the disorder in the distribution of the negative - U dipole
centers in the upper and down delta - barriers.


title: 1-Visibility Representations of 1-Planar Graphs

abstract:
  A visibility representation is a classical drawing style of planar graphs. It
displays the vertices of a graph as horizontal vertex-segments, and each edge
is represented by a vertical edge-segment touching the segments of its end
vertices; beyond that segments do not intersect. We generalize visibility to
1-visibility, where each edge- (vertex-) segment crosses at most one vertex-
(edge-) segment. In other words, a vertex is crossed by at most one edge, and
vice-versa. We show that 1-visibility properly extends 1-planarity and develop
a linear time algorithm to compute a 1-visibility representation of an embedded
1-planar graph on O(n^2) area. A graph is 1-planar if it can be drawn in the
plane such that each edge is crossed at most once. Concerning density, both
1-visible and 1-planar graphs of size $n$ have at most 4n-8 edges. However, for
every n >= 7 there are 1-visible graphs with 4n-8 edge which are not 1-planar.


title: The Hodge spectrum of analytic germs on isolated surface singularities

abstract:
  We use topological methods to prove a semicontinuity property of the Hodge
spectra for analytic germs defined on an isolated surface singularity. For this
we introduce an analogue of the Seifert matrix (the fractured Seifert matrix),
and of the Levine--Tristram signatures associated with it, defined for
null-homologous links in arbitrary three dimensional manifolds. Moreover, we
establish Murasugi type inequalities in the presence of cobordisms of links.
  It turns out that the fractured Seifert matrix determines the Hodge spectrum
and the Murasugi type inequalities can be read as spectrum semicontinuity
inequalities.


title: A special modulus of continuity and the K-functional

abstract:
  We consider the questions connected with the approximation of a real
continuous 1-periodic functions and give a new proof of the equivalence of the
special Boman-Shapiro modulus of continuity with Peetre's K-functional. We also
prove Jackson's inequality for the approximation by trigonometric polynomials.

Electrically-Detected ESR in Silicon Nanostructures Inserted in
  Microcavities

abstract:
  We present the first findings of the new electrically-detected electron spin
resonance technique (EDESR), which reveal the point defects in the ultra-narrow
silicon quantum wells (Si-QW) confined by the superconductor delta-barriers.
This technique allows the ESR identification without application of an external
cavity, as well as a high frequency source and recorder, and with measuring the
only response of the magnetoresistance, with internal GHz Josephson emission
within frameworks of the normal-mode coupling (NMC) caused by the microcavities
embedded in the Si-QW plane.


title:
The Effect of Dipole Boron Centers on the Electroluminescence of
  Nanoscale Silicon p+-n Junctions

abstract:
  Nanoscale silicon p(+)-n junctions with very high concentration of boron, 5
10^21 cm-3, are found to demonstrate interesting optical properties. Emission
band dominated in near-infrared electroluminescence (EL) spectra possesses high
degree of the linear polarization along preferred crystallographic axis which
can be controlled by the lateral voltage applied in the plane of the p(+)-n
junction. Such behavior together with the temperature dependence of the EL
intensity is attributed to the presence of the self-compensating dipole boron
centers, B(+)-B(-), with negative correlation energy which are identified using
the ESR technique in the nanoscale silicon p(+)-n junctions heavily doped with
boron. The model of the recombination process though the negative-U dipole
boron centers controlling the optical properties of the nanoscale silicon
p(+)-n junctions is proposed.


title: Classifying crossed product C*-algebras

abstract:
  I combine recent results in the structure theory of nuclear C*-algebras and
in topological dynamics to classify certain types of crossed products in terms
of their Elliott invariants. In particular, transformation group C*-algebras
associated to free minimal Z^d-actions on the Cantor set with compact space of
ergodic measures are classified by their ordered K-theory. In fact, the
respective statement holds for finite dimensional compact metrizable spaces,
provided that projections of the crossed products separate tracial states.
Moreover, C*-algebras associated to certain minimal homeomorphisms of odd
dimensional spheres are only determined by their spaces of invariant Borel
probability measures (without a condition on the space of ergodic measures).
Finally, I show that for a large collection of classifiable C*-algebras,
crossed products by Z^d-actions are generically again classifiable.


title: The Hilbert-Kunz functions of two-dimensional rings of type ADE

abstract:
  We compute the Hilbert-Kunz functions of two-dimensional rings of type ADE by
using representations of their indecomposable, maximal Cohen-Macaulay modules
in terms of matrix factorizations, and as first syzygy modules of homogeneous
ideals.

Highly sensitive ammonia sensor using reflection of light at a glass -
  photonic crystal interface

abstract:
  We have discovered and studied the effect of the asymmetric deformation of a
photonic crystal in the form of a change in the slope of the crystal planes as
it is filled with a gaseous analyte. We have demonstrated that the use of a new
effect leading to the displacement of the stop band against the unchanged
spectrum of diffracted white light at the (glass-thin opal film) interface can
be used as fast, compact, high sensitive and reproducible optical chemical
sensor for ammonia. Low cost and simplicity of sensor fabrication, the response
of which can be easily observed without resorting to spectral instruments are
therefore likely to be attractive. The basis for high sensitivity (1 ppm), fast
response (120 ms) is capillary vapor condensation. On the basis of this effect
a cheap high-speed and highly sensitive gas sensors has been built.

On normal subgroups of $D^*$ whose elements are periodic modulo the
  center of $D$ of bounded order

abstract:
  Let $D$ be a division ring with the center $F=Z(D)$. Suppose that $N$ is a
normal subgroup of $D^*$ which is radical over $F$, that is, for any element
$x\in N$, there exists a positive integer $n_x$, such that $x^{n_x}\in F$. In
\cite{Her1}, Herstein conjectured that $N$ is contained in $F$. In this paper,
we show that the conjecture is true if there exists a positive integer $d$ such
that $n_x\le d$ for any $x\in N$


title: A holographic model of SQUID

abstract:
  We construct a holographic model of superconducting quantum interference
device (SQUID) in the Einstein-Maxwell-complex scalar theory with a negative
cosmological constant. The SQUID ring consists of two Josephson junctions which
sit on two sides of a compactified spatial direction of a Schwarzschild-AdS
black brane. These two junctions interfere with each other and then result in a
total current depending on the magnetic flux, which can be deduced from the
phase differences of the two Josephson junctions. The relation between the
total current and the magnetic flux is obtained numerically.

Direct Observation of Interface and Nanoscale Compositional Modulation
  in Ternary III-As Heterostructure Nanowires

abstract:
  Straight, axial InAs nanowire with multiple segments of GaInAs were grown.
High resolution X-ray energy-dispersive spectroscopy (EDS) mapping reveal the
distribution of group III atoms at the axial interfaces and at the sidewalls.
Significant Ga enrichment, accompanied by a structural change is observed at
the GaInAs/InAs interfaces and a higher Ga concentration for the early grown
GaInAs segments. The elemental map and EDS line profile infer Ga enrichment at
the facet junctions between the sidewalls. The relative chemical potentials of
ternary alloys and the thermodynamic driving force for liquid to solid
transition explains the growth mechanisms behind the enrichment.


title:
Whittaker periods, motivic periods, and special values of tensor product
  L-functions

abstract:
  Let $\mathcal K$ be an imaginary quadratic field. Let $\Pi$ and $\Pi'$ be
irreducible generic cohomological automorphic representation of
$GL(n)/{\mathcal K}$ and $GL(n-1)/{\mathcal K}$, respectively. Each of them can
be given two natural rational structures over number fields. One is defined by
the rational structure on topological cohomology, the other is given in terms
of the Whittaker model. The ratio between these rational structures is called a
{\it Whittaker period}. An argument presented by Mahnkopf and Raghuram shows
that, at least if $\Pi$ is cuspidal and the weights of $\Pi$ and $\Pi'$ are in
a standard relative position, the critical values of the Rankin-Selberg product
$L(s,\Pi \times \Pi')$ are essentially algebraic multiples of the product of
the Whittaker periods of $\Pi$ and $\Pi'$. We show that, under certain
regularity and polarization hypotheses, the Whittaker period of a cuspidal
$\Pi$ can be given a motivic interpretation, and can also be related to a
critical value of the adjoint $L$-function of related automorphic
representations of unitary groups. The resulting expressions for critical
values of the Rankin-Selberg and adjoint $L$-functions are compatible with
Deligne's conjecture.


title: Security Protocol Review Method Analyzer(SPRMAN)

abstract:
  This Paper is designed using J2EE (JSP, SERVLET), HTML as front end and a
Oracle 9i is back end. SPRMAN is been developed for the client British Telecom
(BT) UK., Telecom company. Actually the requirement of BT is, they are
providing Network Security Related Products to their IT customers like
Virtusa,Wipro,HCL etc., This product is framed out by set of protocols and
these protocols are been associated with set of components. By grouping all
these protocols and components together, product is been developed. After
framing out the product, it is been subscribed to their individual customers.
Once a customer subscribed the product, then he will be raising a request to
the client (BT) for updating any policy or component in the product. The
customer has been given read/write access to the subscribed product. The
customer user having read/write access is only allowed to raise a request for
the product, but not the user having only the read access. The group of request
is been managed as manage work queue in client area. Management of this
protocol inside the product is considering as Security Protocol Review Method
Analyzer. SPRMAN helps BT to overcome all the hurdles faced by them while
processing the requests of their various clients using their already existing
software applications. SPRMAN emphasizes on nature of the request and gives
priority to issues based on their degree of future consequences. Thus SPRMAN
builds a good relationship between BT and its customers.

Multi-Channel Deficit Round-Robin Scheduling for Hybrid TDM/WDM Optical
  Networks

abstract:
  In this paper we propose and investigate the performance of a multi-channel
scheduling algorithm based on the well-known deficit round-robin (DRR), which
we call multi-channel DRR (MCDRR). We extend the original DRR to the case of
multiple channels with tunable transmitters and fixed receivers to provide
efficient fair queueing in hybrid time division multiplexing (TDM)/wavelength
division multiplexing (WDM) optical networks. We take into account the
availability of channels and tunable transmitters in extending the DRR and
allow the overlap of `rounds' in scheduling to efficiently utilize channels and
tunable transmitters. Simulation results show that the proposed MCDRR can
provide nearly perfect fairness with ill-behaved flows for different sets of
conditions for interframe times and frame sizes in hybrid TDM/WDM optical
networks with tunable transmitters and fixed receivers.

Invariants of the single impurity Anderson model and implications for
  conductance functionals

abstract:
  An exact relation between the conductance maximum $G_0$ at zero temperature
and a ratio of lead densities is derived within the framework of the single
impurity Anderson model: $G_0={\mathfrak R}[n] \frac{2e^2}{h}$, where
${\mathfrak R}[n]=4\Delta N_{{\cal L},x} \Delta N_{{\cal R},x}/(\Delta N_{{\cal
L},x}+\Delta N_{{\cal R},x})^2$ and $\Delta N_{{\cal L},x}$, $\Delta N_{{\cal
R},x}$ denote the excess density in the left/right lead at distance $x$ due to
the presence of the impurity at the origin, $x=0$. The relation constitutes a
parameter-free expression of the conductance of the model in terms of the
ground state density that generalizes an earlier result to the generic case of
asymmetric lead couplings. It turns out that the specific density ratio,
${\mathfrak R}[n]$, is independent of the distance to the impurity $x$, the
(magnetic) band-structure and filling fraction of the contacting wires, the
strength of the onsite interaction, the gate voltage and the temperature.
Disorder induced backscattering in the contacting wires has an impact on
${\mathfrak R}$ that we discuss. Our result suggests that it should be
possible, in principle, to determine experimentally the peak conductance of the
Anderson impurity by performing a combination of measurements of ground-state
densities.


title: Complexity of evolutionary equilibria in static fitness landscapes

abstract:
  A fitness landscape is a genetic space -- with two genotypes adjacent if they
differ in a single locus -- and a fitness function. Evolutionary dynamics
produce a flow on this landscape from lower fitness to higher; reaching
equilibrium only if a local fitness peak is found. I use computational
complexity to question the common assumption that evolution on static fitness
landscapes can quickly reach a local fitness peak. I do this by showing that
the popular NK model of rugged fitness landscapes is PLS-complete for K >= 2;
the reduction from Weighted 2SAT is a bijection on adaptive walks, so there are
NK fitness landscapes where every adaptive path from some vertices is of
exponential length. Alternatively -- under the standard complexity theoretic
assumption that there are problems in PLS not solvable in polynomial time --
this means that there are no evolutionary dynamics (known, or to be discovered,
and not necessarily following adaptive paths) that can converge to a local
fitness peak on all NK landscapes with K = 2. Applying results from the
analysis of simplex algorithms, I show that there exist single-peaked
landscapes with no reciprocal sign epistasis where the expected length of an
adaptive path following strong selection weak mutation dynamics is
$e^{O(n^{1/3})}$ even though an adaptive path to the optimum of length less
than n is available from every vertex. The technical results are written to be
accessible to mathematical biologists without a computer science background,
and the biological literature is summarized for the convenience of
non-biologists with the aim to open a constructive dialogue between the two
disciplines.

Modeling of subsurface ice mantle on interstellar dust grains with
  astrochemical code ALCHEMIC (research note)

abstract:
  Interstellar ices are layers of molecules deposited on !ne dust grains in
dark and dense molecular cloud cores. Subsurface ice has been considered in a
few astrochemical models, which have shown that it can be of great importance.
The aim of this work is to introduce an established subsurface ice description
into the state-of-the-art astrochemical model ALCHEMIC. The model has been
developed by the Heidelberg astrochemistry group. The result is an up-to-date
model for interstellar molecular cloud research with possible application for
protoplanetary disks.

On the spectral gap of the kac walk and other binary collision processes
  on $d$-dimensional lattice

abstract:
  We give a lower bound on the spectral gap for a class of binary collision
processes. In 2008, Caputo showed that, for a class of binary collision
processes given by simple averages on the complete graph, the analysis of the
spectral gap of an $N$-component system is reduced to that of the same system
for N=3 In this paper, we give a comparison technique to reduce the analysis of
the spectral gap of binary collision processes given by simple averages on
$d$-dimensional lattice to that on the complete graph. We also give a
comparison technique to reduce the analysis of the spectral gap of binary
collision processes which are not given by simple averages to that given by
simple averages. Combining them with Caputo's result, we give a new and
elementary method to obtain spectral gap estimates. The method applies to a
number of binary collision processes on the complete graph and also on
d-dimensional lattice, including a class of energy exchange models which was
recently introduced in by Grigo et al., and zero-range processes.

Foundations of Quantum Gravity : The Role of Principles Grounded in
  Empirical Reality

abstract:
  When attempting to assess the strengths and weaknesses of various principles
in their potential role of guiding the formulation of a theory of quantum
gravity, it is crucial to distinguish between principles which are strongly
supported by empirical data - either directly or indirectly - and principles
which instead (merely) rely heavily on theoretical arguments for their
justification. These remarks are illustrated in terms of the current standard
models of cosmology and particle physics, as well as their respective
underlying theories, viz. general relativity and quantum (field) theory. It is
argued that if history is to be of any guidance, the best chance to obtain the
key structural features of a putative quantum gravity theory is by deducing
them, in some form, from the appropriate empirical principles (analogous to the
manner in which, say, the idea that gravitation is a curved spacetime
phenomenon is arguably implied by the equivalence principle). It is
subsequently argued that the appropriate empirical principles for quantum
gravity should at least include (i) quantum nonlocality, (ii) irreducible
indeterminacy, (iii) the thermodynamic arrow of time, (iv) homogeneity and
isotropy of the observable universe on the largest scales. In each case, it is
explained - when appropriate - how the principle in question could be
implemented mathematically in a theory of quantum gravity, why it is considered
to be of fundamental significance and also why contemporary accounts of it are
insufficient.

An Experimental Implementation of Oblivious Transfer in the Noisy
  Storage Model

abstract:
  Cryptography's importance in our everyday lives continues to grow in our
increasingly digital world. Oblivious transfer (OT) has long been a fundamental
and important cryptographic primitive since it is known that general two-party
cryptographic tasks can be built from this basic building block. Here we show
the experimental implementation of a 1-2 random oblivious transfer (ROT)
protocol by performing measurements on polarization-entangled photon pairs in a
modified entangled quantum key distribution system, followed by all of the
necessary classical post-processing including one-way error correction. We
successfully exchange a 1,366 bits ROT string in ~3 min and include a full
security analysis under the noisy storage model, accounting for all
experimental error rates and finite size effects. This demonstrates the
feasibility of using today's quantum technologies to implement secure two-party
protocols.


title: Melting dynamics of large ice balls in a turbulent swirling flow

abstract:
  We study the melting dynamics of large ice balls in a turbulent von Karman
flow at very high Reynolds number. Using an optical shadowgraphy setup, we
record the time evolution of particle sizes. We study the heat transfer as a
function of the particle scale Reynolds number for three cases: fixed ice balls
melting in a region of strong turbulence with zero mean flow, fixed ice balls
melting under the action of a strong mean flow with lower fluctuations, and ice
balls freely advected in the whole flow. For the fixed particles cases, heat
transfer is observed to be much stronger than in laminar flows, the Nusselt
number behaving as a power law of the Reynolds number of exponent 0.8. For
freely advected ice balls, the turbulent transfer is further enhanced and the
Nusselt number is proportional to the Reynolds number. The surface heat flux is
then independent of the particles size, leading to an ultimate regime of heat
transfer reached when the thermal boundary layer is fully turbulent.

Stability results for second-order evolution equations with switching
  time-delay

abstract:
  We consider second-order evolution equations in an abstract setting with
intermittently delayed/ not-delayed damping. We give sufficient conditions for
asymptotic and exponential stability, improving and generalising our previous
results from [19]. In particular, under suitable conditions, we can consider
unbounded damping operators. Some concrete examples are finally presented.


title: Spherical designs of harmonic index t

abstract:
  Spherical $t$-design is a finite subset on sphere such that, for any
polynomial of degree at most $t$, the average value of the integral on sphere
can be replaced by the average value at the finite subset. It is well-known
that an equivalent condition of spherical design is given in terms of harmonic
polynomials. In this paper, we define a spherical design of harmonic index $t$
from the viewpoint of this equivalent condition, and we give its construction
and a Fisher type lower bound on the cardinality. Also we investigate whether
there is a spherical design of harmonic index attaining the bound.


title: Measurement-based quantum computation with trapped ions

abstract:
  Measurement-based quantum computation (MBQC) represents a powerful and
flexible framework for quantum information processing, based on the notion of
entangled quantum states as computational resources. The most prominent
application is the one-way quantum computer, with the cluster state as its
universal resource. Here we demonstrate the principles of MBQC using
deterministically generated graph states of up to 7 qubits, in a system of
trapped atomic ions. Firstly we implement a universal set of operations for
quantum computing. Secondly we demonstrate a family of measurement-based
quantum error correction codes, and show their improved performance as the code
length is increased. We show that all our graph states violate a multipartite
Bell inequality and are therefore capable of information processing tasks that
cannot be described by a local hidden variable model. The methods presented can
directly be scaled up to generate graph states of several tens of qubits.


title: On bi-exactness of discrete quantum groups

abstract:
  We define Ozawa's notion of bi-exactness to discrete quantum groups, and then
prove some structural properties of associated von Neumann algebras. In
particular, we prove that any non amenable subfactor of free quantum group von
Neumann algebras, which is an image of a faithful normal conditional
expectation, has no Cartan subalgebras.


title: Verma modules for Iwasawa algebras are faithful

abstract:
  We establish the faithfulness of Verma modules for rational Iwasawa algebras
of split semisimple compact $L$-analytic groups. We also prove the algebraic
independence of Arens-Michael envelopes over Iwasawa algebras and compute the
centre of affinoid enveloping algebras of semisimple $p$-adic Lie algebras.


title: Tensile & shear strength of porous dust agglomerates

abstract:
  Context.Within the sequential accretion scenario of planet formation, planets
are build up through a sequence sticking collisions. The outcome of collisions
between porous dust aggregates is very important for the growth from very small
dust particles to planetesimals. In this work we determine the necessary
material properties of dust aggregates as a function the porosity.
  Aims: Continuum models such as SPH that are capable of simulating collisions
of macroscopic dust aggregates require a set of material parameters. Some of
them such as the tensile and shear strength are difficult to obtain from
laboratory experiments. The aim of this work is to determine these parameters
from ab-initio molecular dynamics simulations.
  Methods: We simulate the behavior of porous dust aggregates using a detailed
micro-physical model of the interaction of spherical grains that includes
adhesion forces, rolling, twisting, and sliding. Using different methods of
preparing the samples we study the strength behavior of our samples with
varying porosity and coordination number of the material.
  Results: For the tensile strength, we can reproduce data from laboratory
experiments very well. For the shear strength, there are no experimental data
available. The results from our simulations differ significantly from previous
theoretical models, which indicates that the latter might not be sufficient to
describe porous dust aggregates.
  Conclusions: We have provided functional behavior of tensile and shear
strength of porous dust aggregates as a function of the porosity that can be
directly applied in continuum simulations of these objects in planet formation
scenarios.


title: Stabilization of second-order evolution equations with time delay

abstract:
  We consider second-order evolution equations in an abstract setting with
damping and time delay and give sufficient conditions ensuring exponential
stability. Our abstract framework is then applied to the wave equation, the
elasticity system and the Petrovsky system.


title: Fractional Josephson effect in a quadruple quantum dot

abstract:
  A double quantum dot coupled to an s-wave superconductor and subject to an
inhomogeneous magnetic field can host a pair of zero-energy Majorana fermions
when the dot properties are tuned appropriately. Here, we demonstrate the
possibility to generate a fractional 4-pi Josephson effect in two such double
dots tunnel-coupled to each other. We discuss the robustness of this effect
with respect to perturbations away from the special point in parameter space
where the uncoupled double dots host Majorana fermions. We demonstrate the
possibility to generate Josephson effects with a period of 8-pi and 12-pi in
strongly-coupled double dots.

Sur les champs de vecteurs invariants sur l'espace tangent d'un espace
  sym\'etrique

abstract:
  Let $G$ be a real reductive connected Lie group and $\sigma$ an involution of
$G$. Let $H$ denote the identity component of the group of fixed points of
$\sigma$, $\mathfrak g$ the Lie algebra of $G$ and $\mathfrak q$ the -1
eigenspace of $\sigma$ in $\mathfrak g$. The group $H$ acts naturally on
$\mathfrak q$ via the adjoint representation. Let $C^{\infty}(\mathfrak q)^H$
denote the algebra of $H$-invariant smooth functions on $\mathfrak q$, and
$\mathfrak X(\mathfrak q)^H$ the space of $H$-invariant smooth vetor fields on
$\mathfrak q$. Any vetor field $X\in \mathfrak X(\mathfrak q)^H$ defines
naturally a derivation $D_X$ of the algebra $C^{\infty}(\mathfrak q)^H$. We
prove that the image of the map $X\mapsto D_X$ is the set of derivations of the
algebra $C^{\infty}(\mathfrak q)^H$ preserving the ideal
$\it{\Phi}C^{\infty}(\mathfrak q)^H$ of $C^{\infty}(\mathfrak q)^H$, where
$\it{\Phi}$ is a discriminant function on $\mathfrak q$.


title: Final model independent result of DAMA/LIBRA-phase1

abstract:
  The results obtained with the total exposure of 1.04 ton x yr collected by
DAMA/LIBRA-phase1 deep underground at the Gran Sasso National Laboratory (LNGS)
of the I.N.F.N. during 7 annual cycles (i.e. adding a further 0.17 ton x yr
exposure) are presented. The DAMA/LIBRA-phase1 data give evidence for the
presence of Dark Matter (DM) particles in the galactic halo, on the basis of
the exploited model independent DM annual modulation signature by using highly
radio-pure NaI(Tl) target, at 7.5 sigma C.L.. Including also the first
generation DAMA/NaI experiment (cumulative exposure 1.33 ton x yr,
corresponding to 14 annual cycles), the C.L. is 9.3 sigma and the modulation
amplitude of the single-hit events in the (2-6) keV energy interval is: (0.0112
\pm 0.0012) cpd/kg/keV; the measured phase is (144 \pm 7) days and the measured
period is (0.998 \pm 0.002) yr, values well in agreement with those expected
for DM particles. No systematic or side reaction able to mimic the exploited DM
signature has been found or suggested by anyone over more than a decade.


title: Derivation of the TCP Theorem using Action Principles

abstract:
  We present a new derivation of the proof for the TCP/CPT Theorem using the
Dynamical Principle and Variation of Action methods first defined by Schwinger
in 1951. This new proof will significantly extend the TCP Theorem beyond the
original proofs by Pauli-Luders and Jost, which were significantly constrained
by limits of free quantum fields and the asymptotic condition. This paper gives
a more fundamental proof based on invariance of the Variation of Action with
interactions included and no free field or asymptotic condition on the quantum
fields. This new proof for TCP/CPT can now be applied to more complicated
quantum field systems that include n-particle bound states and unstable states.


title:
Unified Models of Molecular Emission from Class 0 Protostellar Outflow
  Sources

abstract:
  Low mass star-forming regions are more complex than the simple spherically
symmetric approximation that is often assumed. We apply a more realistic
infall/outflow physical model to molecular/continuum observations of three late
Class 0 protostellar sources with the aims of (a) proving the applicability of
a single physical model for all three sources, and (b) deriving physical
parameters for the molecular gas component in each of the sources.
  We have observed several molecular species in multiple rotational
transitions. The observed line profiles were modelled in the context of a
dynamical model which incorporates infall and bipolar outflows, using a three
dimensional radiative transfer code. This results in constraints on the
physical parameters and chemical abundances in each source.
  Self-consistent fits to each source are obtained. We constrain the
characteristics of the molecular gas in the envelopes as well as in the
molecular outflows. We find that the molecular gas abundances in the infalling
envelope are reduced, presumably due to freeze-out, whilst the abundances in
the molecular outflows are enhanced, presumably due to dynamical activity.
Despite the fact that the line profiles show significant source-to-source
variation, which primarily derives from variations in the outflow viewing
angle, the physical parameters of the gas are found to be similar in each core.


title: Random compact set meets the graph of nonrandom continuous function

abstract:
  On the plane, every random compact set with almost surely uncountable first
projection intersects with a high probability the graph of some continuous
function. Implication: every black noise over the plane fails to factorize when
the plane is split by such graph.


title:
Strongly star-forming rotating disks in a complex merging system at z =
  4,7 as revealed by ALMA

abstract:
  We performed a kinematical analysis of the [CII] line emission of the BR
1202-0725 system at z~4,7 using ALMA observations. The most prominent sources
of this system are a quasar and a submillimeter galaxy, separated by a
projected distance of about 24 kpc and characterized by very high SFR, higher
than 1000 Msun/yr. However, the ALMA observations reveal that these galaxies
apparently have undisturbed rotating disks, which is at variance with the
commonly accepted scenario in which strong star formation activity is induced
by a major merger. We also detected faint components which, after spectral
deblending, were spatially resolved from the main QSO and SMG emissions. The
relative velocities and positions of these components are compatible with
orbital motions within the gravitational potentials generated by the QSO host
galaxy and the SMG, suggesting that they are smaller galaxies in interaction or
gas clouds in accretion flows of tidal streams. We did not find any clear
spectral evidence for outflows caused by AGN or stellar feedback. This suggests
that the high star formation rates might be induced by interactions or minor
mergers with these companions, which do not affect the large-scale kinematics
of the disks, however. Our kinematical analysis also indicates that the QSO and
the SMG have similar Mdyn, mostly in the form of molecular gas, and that the
QSO host galaxy and the SMG are seen close to face-on with slightly different
disk inclinations: the QSO host galaxy is seen almost face-on (i~15), while the
SMG is seen at higher inclinations (i~25). Finally, the ratio between the black
hole mass of the QSO, obtained from XShooter spectroscopy, and the Mdyn of the
host galaxy is similar to value found in very massive local galaxies,
suggesting that the evolution of black hole galaxy relations is probably better
studied with dynamical than with stellar host galaxy masses.


title:
Monte Carlo Simulations of Nonlinear Particle Acceleration in Parallel
  Trans-relativistic Shocks

abstract:
  We present results from a Monte Carlo simulation of a parallel collisionless
shock undergoing particle acceleration. Our simulation, which contains
parameterized scattering and a particular thermal leakage injection model,
calculates the feedback between accelerated particles ahead of the shock, which
influence the shock precursor and "smooth" the shock, and thermal particle
injection. We show that there is a transition between nonrelativistic shocks,
where the acceleration efficiency can be extremely high and the nonlinear
compression ratio can be substantially greater than the Rankine-Hugoniot value,
and fully relativistic shocks, where diffusive shock acceleration is less
efficient and the compression ratio remains at the Rankine-Hugoniot value. This
transition occurs in the trans-relativistic regime and, for the particular
parameters we use, occurs around a shock Lorentz factor = 1.5. We also find
that nonlinear shock smoothing dramatically reduces the acceleration efficiency
presumed to occur with large-angle scattering in ultra-relativistic shocks. Our
ability to seamlessly treat the transition from ultra-relativistic to
trans-relativistic to nonrelativistic shocks may be important for evolving
relativistic systems, such as gamma-ray bursts and type Ibc supernovae. We
expect a substantial evolution of shock accelerated spectra during this
transition from soft early on to much harder when the blast-wave shock becomes
nonrelativistic.


title: Power-law models for infectious disease spread

abstract:
  Short-time human travel behaviour can be described by a power law with
respect to distance. We incorporate this information in space-time models for
infectious disease surveillance data to better capture the dynamics of disease
spread. Two previously established model classes are extended, which both
decompose disease risk additively into endemic and epidemic components: a
spatio-temporal point process model for individual-level data and a
multivariate time-series model for aggregated count data. In both frameworks, a
power-law decay of spatial interaction is embedded into the epidemic component
and estimated jointly with all other unknown parameters using (penalised)
likelihood inference. Whereas the power law can be based on Euclidean distance
in the point process model, a novel formulation is proposed for count data
where the power law depends on the order of the neighbourhood of discrete
spatial units. The performance of the new approach is investigated by a
reanalysis of individual cases of invasive meningococcal disease in Germany
(2002-2008) and count data on influenza in 140 administrative districts of
Southern Germany (2001-2008). In both applications, the power law substantially
improves model fit and predictions, and is reasonably close to alternative
qualitative formulations, where distance and order of neighbourhood,
respectively, are treated as a factor. Implementation in the R package
surveillance allows the approach to be applied in other settings.

On the distribution of the zeros of the derivative of the Riemann
  zeta-function

abstract:
  We establish an unconditional asymptotic formula describing the horizontal
distribution of the zeros of the derivative of the Riemann zeta-function. For
$\Re(s)=\sigma$ satisfying $(\log T)^{-1/3+\epsilon} \leq (2\sigma-1) \leq
(\log \log T)^{-2}$, we show that the number of zeros of $\zeta'(s)$ with
imaginary part between zero and $T$ and real part larger than $\sigma$ is
asymptotic to $T/(2\pi(\sigma-1/2))$ as $T \rightarrow \infty$. This agrees
with a prediction from random matrix theory due to Mezzadri. Hence, for
$\sigma$ in this range the zeros of $\zeta'(s)$ are horizontally distributed
like the zeros of the derivative of characteristic polynomials of random
unitary matrices are radially distributed.


title: Partition function of beta-gamma system on orbifolds

abstract:
  Partition function of beta-gamma systems on the orbifolds C^2/Z_N and C^3/Z_M
x Z_N are obtained as the invariant part of that on the respective affine
spaces, by lifting the geometric action of the orbifold group to the fields.
Interpreting the sum over roots of unity as an elementary contour integration,
the partition function evaluates to an infinite series counting invariant
monomials composed of basic operators of the theory at each mass level.

On the Strong Coupling Limit of Many-Polaron Systems in Electromagnetic
  Fields

abstract:
  In this paper estimates on the ground state energy of Fr\"ohlich $N$-polarons
in electromagnetic fields in the strong coupling limit, $\alpha\to\infty$, are
derived. It is shown that the ground state energy is given by $\alpha^2$
multiplied by the minimal energy of the corresponding Pekar-Tomasevich
functional for $N$ particles, up to an error term of order $\alpha^{42/23}N^3$.
The potentials $A,V$ are suitably rescaled in $\alpha$. As a corollary, binding
of $N$-polarons for strong magnetic fields for large coupling constants is
established.

Waterfalls around protostars: Infall motions towards Class 0/I envelopes
  as probed by water

abstract:
  Abridged abstract: For stars to form, material must fall inwards from core
scales through the envelope towards the central protostar. The velocity profile
around protostars is poorly constrained. 6 Class 0 protostars and one Class I
protostars observed with HIFI on board Herschel as part of the "Water in
star-forming regions with Herschel" (WISH) survey show infall signatures in
water line observations. We use 1-D non-LTE RATRAN radiative transfer models of
the observed water lines to constrain the infall velocity and chemistry in the
protostellar envelopes of these sources. We assume a free-fall velocity profile
and, having found the best fit, vary the radii over which infall takes place.
In the well-studied Class 0 protostar NGC1333-IRAS4A we find that infall takes
place over the whole envelope to which our observations are sensitive (r>~1000
AU). For 4 sources infall takes place on core to envelope scales (i.e.
~10000-3000 AU). In 2 sources the inverse P-Cygni profiles seen in the
ground-state lines are more likely due to larger-scale motions or foreground
clouds. Models including a simple consideration of the chemistry are consistent
with the observations, while using step abundance profiles are not. The
non-detection of excited water in the inner envelope in 6/7 protostars is
further evidence that water must be heavily depleted from the gas-phase at
these radii. Infall in four of the sources is supersonic and infall in all
sources must take place at the outer edge of the envelope, which may be
evidence that collapse is global or outside-in rather than inside-out. The mass
infall rate in IRAS4A is large (>~10^-4 msol\yr), higher than the mass outflow
rate and expected mass accretion rates onto the star, suggesting that any
flattened disk-like structure on small scales will be gravitationally unstable,
potentially leading to rotational fragmentation and/or episodic accretion.

  We define and characterise regular sequences in affine buildings, thereby
giving the "$p$-adic analogue" of the fundamental work of Kaimanovich. As
applications we prove limit theorems for random walks on affine buildings and
their automorphism groups.

Voter Model with Arbitrary Degree Dependence: Clout, Confidence and
  Irreversibility

abstract:
  In this paper, we consider the voter model with popularity bias. The
influence of each node on its neighbors depends on its degree. We find the
consensus probabilities and expected consensus times for each of the states. We
also find the fixation probability, which is the probability that a single node
whose state differs from every other node imposes its state on the entire
system. In addition, we find the expected fixation time. Then two extensions to
the model are proposed and the motivations behind them are discussed. The first
one is confidence, where in addition to the states of neighbors, nodes take
their own state into account at each update. We repeat the calculations for the
augmented model and investigate the effects of adding confidence to the model.
The second proposed extension is irreversibility, where one of the states is
given the property that once nodes adopt it, they cannot switch back. The
dynamics of densities, fixation times and consensus times are obtained.

title: Quotients and subgroups of Baumslag-Solitar groups

abstract:
  We determine all generalized Baumslag-Solitar groups (finitely generated
groups acting on a tree with all stabilizers infinite cyclic) which are
quotients of a given Baumslag-Solitar group BS(m,n), and (when BS(m,n) is not
Hopfian) which of them also admit BS(m,n) as a quotient. We determine for which
values of r,s one may embed BS(r,s) into a given BS(m,n), and we characterize
finitely generated groups which embed into some BS(n,n).

Relationship between Fermi-Surface Warping and Out-of-Plane Spin
  Polarization in Topological Insulators: a View from Spin-Resolved ARPES

abstract:
  We have performed spin- and angle-resolved photoemission spectroscopy of the
topological insulator Pb(Bi,Sb)2Te4 (Pb124) and observed significant
out-of-plane spin polarization on the hexagonally warped Dirac-cone surface
state. To put this into context, we carried out quantitative analysis of the
warping strengths for various topological insulators (Pb124, Bi2Te3, Bi2Se3,
and TlBiSe2) and elucidated that the out-of-plane spin polarization Pz is
systematically correlated with the warping strength. However, the magnitude of
Pz is found to be only half of that expected from the kp theory when the
warping is strong, which points to the possible role of many-body effects.
Besides confirming a universal relationship between the spin polarization and
the surface state structure, our data provide an empirical guiding principle
for tuning the spin polarization in topological insulators.


title: Distinct cell shapes determine accurate chemotaxis

abstract:
  The behaviour of an organism often reflects a strategy for coping with its
environment. Such behaviour in higher organisms can often be reduced to a few
stereotyped modes of movement due to physiological limitations, but finding
such modes in amoeboid cells is more difficult as they lack these constraints.
Here, we examine cell shape and movement in starved Dictyostelium amoebae
during migration toward a chemoattractant in a microfluidic chamber. We show
that the incredible variety in amoeboid shape across a population can be
reduced to a few modes of variation. Interestingly, cells use distinct modes
depending on the applied chemical gradient, with specific cell shapes
associated with shallow, difficult-to-sense gradients. Modelling and drug
treatment reveals that these behaviours are intrinsically linked with accurate
sensing at the physical limit. Since similar behaviours are observed in a
diverse range of cell types, we propose that cell shape and behaviour are
conserved traits.

Discovering Latent Patterns from the Analysis of User-Curated Movie
  Lists

abstract:
  User content curation is becoming an important source of preference data, as
well as providing information regarding the items being curated. One popular
approach involves the creation of lists. On Twitter, these lists might contain
accounts relevant to a particular topic, whereas on a community site such as
the Internet Movie Database (IMDb), this might take the form of lists of movies
sharing common characteristics. While list curation involves substantial
combined effort on the part of users, researchers have rarely looked at mining
the outputs of this kind of crowdsourcing activity. Here we study a large
collection of movie lists from IMDb. We apply network analysis methods to a
graph that reflects the degree to which pairs of movies are "co-listed", that
is, assigned to the same lists. This allows us to uncover a more nuanced
grouping of movies that goes beyond categorisation schemes based on attributes
such as genre or director.


title: Equivalence transformations in the study of integrability

abstract:
  We discuss how point transformations can be used for the study of
integrability, in particular, for deriving classes of integrable
variable-coefficient differential equations. The procedure of finding the
equivalence groupoid of a class of differential equations is described and then
specified for the case of evolution equations. A class of fifth-order
variable-coefficient KdV-like equations is studied within the framework
suggested.


title: On the gauge independence of the fermion pole mass

abstract:
  We study the question of complete gauge independence of the fermion pole mass
by choosing a general class of gauge fixing which interpolates between the
covariant, the axial and the Coulomb gauges for different values of the gauge
fixing parameters. We derive the Nielsen identity describing the gauge
parameter variation of the fermion two point function in this general class of
gauges. Furthermore, we relate the denominator of the fermion propagator to the
two point function. This then allows us to study directly the gauge parameter
dependence of the denominator of the propa- gator using the Nielsen identity
for the two point function. This leads to a simple proof that, when infrared
divergences and mass shell singularities are not present at the pole, the
fermion pole mass is gauge independent, in the complete sense, to all orders in
perturbation theory. Namely, the pole is not only independent of the gauge
fixing parameters, but has also the same value in both covariant and
non-covariant gauges.

On the facial Thue choice number of plane graphs via entropy compression
  method

abstract:
  Let $G$ be a plane graph. A vertex-colouring $\varphi$ of $G$ is called {\em
facial non-repetitive} if for no sequence $r_1 r_2 \dots r_{2n}$, $n\geq 1$, of
consecutive vertex colours of any facial path it holds $r_i=r_{n+i}$ for all
$i=1,2,\dots,n$. A plane graph $G$ is {\em facial non-repetitively
$l$-choosable} if for every list assignment $L:V\rightarrow 2\sp{\mathbb{N}}$
with minimum list size at least $l$ there is a facial non-repetitive
vertex-colouring $\varphi$ with colours from the associated lists. The {\em
facial Thue choice number}, $\pi_{fl}(G)$, of a plane graph $G$ is the minimum
number $l$ such that $G$ is facial non-repetitively $l$-choosable. %In this
article we We use the so-called entropy compression method to show that
$\pi_{fl} (G)\le c \Delta$ for some absolute constant $c$ and $G$ a plane graph
with maximum degree $\Delta$. Moreover, we give some better (constant) upper
bounds on $\pi_{fl} (G)$ for special classes of plane graphs.

A Study of Selection Methods for H alpha Emitting Galaxies at z~1.3 for
  the Subaru/FMOS Galaxy Redshift Survey for Cosmology (FastSound)

abstract:
  The efficient selection of high-redshift emission galaxies is important for
future large galaxy redshift surveys for cosmology. Here we describe the target
selection methods for the FastSound project, a redshift survey for H alpha
emitting galaxies at z=1.2-1.5 using Subaru/FMOS to measure the linear growth
rate f\sigma 8 via Redshift Space Distortion (RSD) and constrain the theory of
gravity. To select ~400 target galaxies in the 0.2 deg^2 FMOS field-of-view
from photometric data of CFHTLS-Wide (u*g'r'i'z'), we test several different
methods based on color-color diagrams or photometric redshift estimates from
spectral energy distribution (SED) fitting. We also test the improvement in
selection efficiency that can be achieved by adding near-infrared data from the
UKIDSS DXS (J). The success rates of H alpha detection with FMOS averaged over
two observed fields using these methods are 11.3% (color-color, optical), 13.6%
(color-color, optical+NIR), 17.3% (photo-z, optical), and 15.1% (photo-z,
optical+NIR). Selection from photometric redshifts tends to give a better
efficiency than color-based methods, although there is no significant
improvement by adding J band data within the statistical scatter. We also
investigate the main limiting factors for the success rate, by using the sample
of the HiZELS H alpha emitters that were selected by narrow-band imaging.
Although the number density of total H alpha emitters having higher H alpha
fluxes than the FMOS sensitivity is comparable with the FMOS fiber density, the
limited accuracy of photometric redshift and H alpha flux estimations have
comparable effects on the success rate of <~20% obtained from SED fitting.

Towards Realizing a Quantum Memory for a Superconducting Qubit: Storage
  and Retrieval of quantum states

abstract:
  We have built a hybrid system composed of a superconducting flux qubit (the
processor) and an ensemble of nitrogen-vacancy centers in diamond (the memory)
that can be directly coupled to one another and demonstrated how information
can be transferred from the flux qubit to the memory, stored and subsequently
retrieved. We have established the coherence properties of the memory, and
succeeded in creating an entangled state between the processor and memory,
demonstrating how the entangled state's coherence is preserved. Our results are
a significant step towards using an electron spin ensemble as a quantum memory
for superconducting qubits.


title: Brackets in the Pontryagin algebras of manifolds

abstract:
  Given a smooth oriented manifold $M$ with non-empty boundary, we study the
Pontryagin algebra $A=H_\ast(\Omega )$ where $ \Omega $ is the space of loops
in $M$ based at a distinguished point of $ \partial M$. Using the ideas of
string topology of Chas-Sullivan, we define a linear map $\{\{-,-\}\}: A
\otimes A \to A\otimes A$ which is a double bracket in the sense of Van den
Bergh satisfying a version of the Jacobi identity. For $\dim(M)\geq 3$, the
double bracket $\{\{-,-\}\}$ induces Gerstenhaber brackets in the
representation algebras associated with $A$. This extends our previous work on
the case $\dim(M)=2$ where $A= H_0(\Omega )$ is the group algebra of the
fundamental group $\pi_1(M)$ and the double bracket $\{\{-,-\}\}$ induces the
standard Poisson brackets on the moduli spaces of representations of
$\pi_1(M)$.


title: Statistical Mechanical Treatments of Protein Amyloid Formation

abstract:
  Protein aggregation is an important field of investigation because it is
closely related to the problem of neurodegenerative diseases, to the
development of biomaterials, and to the growth of cellular structures such as
cyto-skeleton. Self-aggregation of protein amyloids, for example, is a
complicated process involving many species and levels of structures. This
complexity, however, can be dealt with using statistical mechanical tools, such
as free energies, partition functions, and transfer matrices. In this article,
we review general strategies for studying protein aggregation using statistical
mechanical approaches and show that canonical and grand canonical ensembles can
be used in such approaches. The grand canonical approach is particularly
convenient since competing pathways of assembly and dis-assembly can be
considered simultaneously. Another advantage of using statistical mechanics is
that numerically exact solutions can be obtained for all of the thermodynamic
properties of fibrils, such as the amount of fibrils formed, as a function of
initial protein concentration. Furthermore, statistical mechanics models can be
used to fit experimental data when they are available for comparison.

Performance Measurement Under Increasing Environmental Uncertainty In
  The Context of Interval Type-2 Fuzzy Logic Based Robotic Sailing

abstract:
  Performance measurement of robotic controllers based on fuzzy logic,
operating under uncertainty, is a subject area which has been somewhat ignored
in the current literature. In this paper standard measures such as RMSE are
shown to be inappropriate for use under conditions where the environmental
uncertainty changes significantly between experiments. An overview of current
methods which have been applied by other authors is presented, followed by a
design of a more sophisticated method of comparison. This method is then
applied to a robotic control problem to observe its outcome compared with a
single measure. Results show that the technique described provides a more
robust method of performance comparison than less complex methods allowing
better comparisons to be drawn.


title: Notoph-Graviton-Photon Coupling

abstract:
  In the sixties Ogievetskii and Polubarinov proposed the concept of a notoph,
whose helicity properties are complementary to those of a photon. Later, Kalb
and Ramond (and others) developed this theoretical concept. And, at the present
times it is widely accepted. We analyze the quantum theory of antisymmetric
tensor fields with taking into account mass dimensions of notoph and photon. It
appears to be possible to describe both photon and notoph degrees of freedom on
the basis of the modified Bargmann-Wigner formalism for the symmetric
second-rank spinor. Next, we proceed to derive equations for the symmetric
tensor of the second rank on the basis of the Bargmann-Wigner formalism in a
straightforward way. The symmetric multispinor of the fourth rank is used. It
is constructed out of the Dirac 4-spinors. Due to serious problems with the
interpretation of the results obtained on using the standard procedure we
generalize it and obtain the spin-2 relativistic equations, which are
consistent with the general relativity. The importance of the 4-vector field
(and its gauge part) is pointed out. Thus, we present the full theory which
contains photon, notoph (the Kalb-Ramond field) and the graviton. The relations
of this theory with the higher spin theories are established. In fact, we
deduced the gravitational field equations from relativistic quantum mechanics.
We estimate possible interactions, fermion-notoph, graviton-notoph,
photon-notoph. PACS number: 03.65.Pm, 04.50.-h, 11.30.Cp

Elastic heterogeneity, vibrational states, and thermal conductivity
  across an amorphisation transition

abstract:
  Disordered solids exhibit unusual properties of their vibrational states and
thermal conductivities. Recent progresses have well established the concept of
"elastic heterogeneity", i.e., disordered materials show spatially
inhomogeneous elastic moduli. In this study, by using molecular-dynamics
simulations, we gradually introduce "disorder" into a numerical system to
control its modulus heterogeneity. The system starts from a perfect crystalline
state, progressively transforms into an increasingly disordered crystalline
state, and finally undergoes structural amorphisation. We monitor independently
the elastic heterogeneity, the vibrational states, and the thermal conductivity
across this transition, and show that the heterogeneity in elastic moduli is
well correlated to vibrational and thermal anomalies of the disordered system.

Extending Similarity Measures of Interval Type-2 Fuzzy Sets to General
  Type-2 Fuzzy Sets

abstract:
  Similarity measures provide one of the core tools that enable reasoning about
fuzzy sets. While many types of similarity measures exist for type-1 and
interval type-2 fuzzy sets, there are very few similarity measures that enable
the comparison of general type-2 fuzzy sets. In this paper, we introduce a
general method for extending existing interval type-2 similarity measures to
similarity measures for general type-2 fuzzy sets. Specifically, we show how
similarity measures for interval type-2 fuzzy sets can be employed in
conjunction with the zSlices based general type-2 representation for fuzzy sets
to provide measures of similarity which preserve all the common properties
(i.e. reflexivity, symmetry, transitivity and overlapping) of the original
interval type-2 similarity measure. We demonstrate examples of such extended
fuzzy measures and provide comparisons between (different types of) interval
and general type-2 fuzzy measures.


title: Measuring the Directional Distance Between Fuzzy Sets

abstract:
  The measure of distance between two fuzzy sets is a fundamental tool within
fuzzy set theory. However, current distance measures within the literature do
not account for the direction of change between fuzzy sets; a useful concept in
a variety of applications, such as Computing With Words. In this paper, we
highlight this utility and introduce a distance measure which takes the
direction between sets into account. We provide details of its application for
normal and non-normal, as well as convex and non-convex fuzzy sets. We
demonstrate the new distance measure using real data from the MovieLens dataset
and establish the benefits of measuring the direction between fuzzy sets.


title: Artificial Immune Systems (INTROS 2)

abstract:
  The biological immune system is a robust, complex, adaptive system that
defends the body from foreign pathogens. It is able to categorize all cells (or
molecules) within the body as self or non-self substances. It does this with
the help of a distributed task force that has the intelligence to take action
from a local and also a global perspective using its network of chemical
messengers for communication. There are two major branches of the immune
system. The innate immune system is an unchanging mechanism that detects and
destroys certain invading organisms, whilst the adaptive immune system responds
to previously unknown foreign cells and builds a response to them that can
remain in the body over a long period of time. This remarkable information
processing biological system has caught the attention of computer science in
recent years.
  A novel computational intelligence technique, inspired by immunology, has
emerged, called Artificial Immune Systems. Several concepts from the immune
system have been extracted and applied for solution to real world science and
engineering problems. In this tutorial, we briefly describe the immune system
metaphors that are relevant to existing Artificial Immune Systems methods. We
will then show illustrative real-world problems suitable for Artificial Immune
Systems and give a step-by-step algorithm walkthrough for one such problem. A
comparison of the Artificial Immune Systems to other well-known algorithms,
areas for future work, tips & tricks and a list of resources will round this
tutorial off. It should be noted that as Artificial Immune Systems is still a
young and evolving field, there is not yet a fixed algorithm template and hence
actual implementations might differ somewhat from time to time and from those
examples given here.

Branching Fractions and Direct CP Violation in Charmless Three-body
  Decays of B Mesons

abstract:
  Charmless three-body decays of B mesons is studied using a simple model based
on the framework of the factorization approach. Hadronic three-body decays
receive both resonant and nonresonant contributions. Dominant nonresonant
contributions to tree-dominated three-body decays arise from the $b\to u$ tree
transition which can be evaluated using heavy meson chiral perturbation theory
valid in the soft meson limit. For penguin-dominated decays, nonresonant
signals come mainly from the penguin amplitude governed by the matrix elements
of scalar densities $<M_1M_2|\bar q_1 q_2|0>$. We use the measurements of $\bar
B^0\to K_SK_SK_S$ to constrain the nonresonant component of $<K\bar K|\bar
ss|0>$. The intermediate vector meson contributions to three-body decays are
identified through the vector current, while the scalar meson resonances are
mainly associated with the scalar density. While the calculated direct CP
violation in $B^-\to K^+K^-K^-$ and $B^-\to \pi^+\pi^-\pi^-$ decays agrees well
with experiment in both magnitude and sign, the predicted CP asymmetries in
$B^-\to \pi^- K^+K^-$ and $B^-\to K^-\pi^+\pi^-$ are wrong in signs when
confronted with experiment. It has been conjectured recently that a possible
resolution to this CP puzzle may rely on final-state rescattering of
$\pi^+\pi^-$ and $K^+K^-$. Assuming a large strong phase associated with the
matrix element $<K\pi|\bar sq|0>$ arising from some sort of power corrections,
we fit it to the data of $K^-\pi^+\pi^-$ and find a correct sign for $\pi^-
K^+K^-$.


title:
Simultaneous reconstruction of evolutionary history and epidemiological
  dynamics from viral sequences with the birth-death SIR model

abstract:
  The evolution of RNA viruses such as HIV, Hepatitis C and Influenza virus
occurs so rapidly that the viruses' genomes contain information on past
ecological dynamics. Hence, we develop a phylodynamic method that enables the
joint estimation of epidemiological parameters and phylogenetic history. Based
on a compartmental susceptible-infected-removed (SIR) model, this method
provides separate information on incidence and prevalence of infections.
Detailed information on the interaction of host population dynamics and
evolutionary history can inform decisions on how to contain or entirely avoid
disease outbreaks.
  We apply our Birth-Death SIR method (BDSIR) to two viral data sets. First,
five human immunodeficiency virus type 1 clusters sampled in the United Kingdom
between 1999 and 2003 are analyzed. The estimated basic reproduction ratios
range from 1.9 to 3.2 among the clusters. All clusters show a decline in the
growth rate of the local epidemic in the middle or end of the 90's.
  The analysis of a hepatitis C virus (HCV) genotype 2c data set shows that the
local epidemic in the C\'ordoban city Cruz del Eje originated around 1906
(median), coinciding with an immigration wave from Europe to central Argentina
that dates from 1880--1920. The estimated time of epidemic peak is around 1970.

Pathwise nonuniqueness for the SPDEs of some super-Brownian motions with
  immigration

abstract:
  We prove pathwise nonuniqueness in the stochastic partial differential
equations (SPDEs) for some one-dimensional super-Brownian motions with
immigration. In contrast to a closely related case investigated by Mueller,
Mytnik and Perkins [Ann. Probab. 42 (2014) 2032-2112], the solutions of the
present SPDEs are assumed to be nonnegative and have very different properties
including uniqueness in law. In proving possible separation of solutions, we
derive delicate properties of certain correlated approximating solutions, which
is based on a novel coupling method called continuous decomposition. In
general, this method may be of independent interest in furnishing solutions of
SPDEs with intrinsic adapted structure.oximating solutions, which may be of
independent interest in the study of superprocesses with immigration.


title: Designing quantum dots for solotronics

abstract:
  Solotronics, optoelectronics based on solitary dopants, is an emerging field
of research and technology reaching the ultimate limit of miniaturization. It
aims at exploiting quantum properties of individual ions or defects embedded in
a semiconductor matrix. As already shown, optical control of a spin of a
magnetic ion is feasible employing photo-generated carriers confined in a
quantum dot. A non-radiative recombination, regarded as a severe problem,
limited development of quantum dots with magnetic ions. Our photoluminescence
studies on, so far unexplored, individual CdTe dots with single cobalt ions and
individual CdSe dots with single manganese ions show, however, that even if
energetically allowed, the single ion related non-radiative recombination is
negligible in such zero-dimensional structures. This opens solotronics for a
wide range of even not yet considered systems. Basing on the results of our
single spin relaxation experiments and on the material trends, we identify
optimal magnetic ion-quantum dot systems for implementation of a single-ion
based spin memory.


title:
Magnetospheric accretion on the fully-convective classical T Tauri star
  DN Tau

abstract:
  We report here results of spectropolarimetric observations of the classical T
Tauri star DN Tau carried out (at 2 epochs) with ESPaDOnS at the
Canada-France-Hawaii Telescope within the `Magnetic Protostars and Planets'
programme. We infer that DN Tau, with a photospheric temperature of 3,950+-50
K, a luminosity of 0.8+-0.2 Lsun and a rotation period of 6.32 d, is a
~2Myr-old fully-convective 0.65+-0.05 Msun star with a radius of 1.9+-0.2 Dsun,
viewed at an inclination of 35+-10degr.
  Clear circularly-polarized Zeeman signatures are detected in both
photospheric and accretion-powered emission lines, probing longitudinal fields
of up to 1.8 kG (in the He1 D3 accretion proxy). Rotational modulation of
Zeeman signatures, detected both in photospheric and accretion lines, is
different between our 2 runs, providing further evidence that fields of cTTSs
are generated by non-stationary dynamos.
  Using tomographic imaging, we reconstruct maps of the large-scale field, of
the photospheric brightness and of the accretion-powered emission at the
surface of DN Tau at both epochs. We find that the magnetic topology is mostly
poloidal, and largely axisymmetric, with an octupolar component (of polar
strength 0.6-0.8 kG) 1.5-2.0x larger than the dipolar component (of polar
strength 0.3-0.5 kG).
  DN Tau features dominantly poleward accretion at both epochs. The large-scale
dipole component of DN Tau is however too weak to disrupt the surrounding
accretion disc further than 65-90% of the corotation radius (at which the disc
Keplerian period matches the stellar rotation period), suggesting that DN Tau
is already spinning up despite being fully convective.


title: Detect adverse drug reactions for drug Pioglitazone

abstract:
  In this study we propose a novel method to successfully detect the ADRs using
feature matrix and feature selection. A feature matrix, which characterizes the
medical events before patients take drugs or after patients take drugs, is
created from THIN database. The feature selection method of Student's t-test is
used to detect the significant features from thousands of medical events. The
significant ADRs, which are corresponding to significant features, are
detected. Experiments are performed on the drug Pioglitazone. Compared to other
computerized methods, our proposed method achieves good performance.


title: MSSM-like models on Z(8) toroidal orbifolds

abstract:
  We extend the promising heterotic string searches for MSSM-like models to Z_8
orbifolds. There exist five inequivalent Z_8 toroidal orbifolds distinguished
by two types of twists that act on five different torus lattices; one of which
cannot be represented as a Lie-algebra root lattice. Contrary to previous
investigations, we study the consequences of the different underlying orbifold
torus lattices. Therefore, rather than focussing on one particular geometry, we
perform systematic model searches on these five Z_8 orbifolds simultaneously,
taking all possible inequivalent SU(5) and SO(10) gauge shifts as our starting
point. We present cumulative Tables and Figures comparing the chiral SM and
vector-like exotic spectra on these geometries.
