Tune shift with amplitude of the system. When the tune reaches resonant values, it can be unstable, and thus a tune-shift with amplitude can limit the stability region, or dynamic aperture. In classical mechanics, a simple example of a system with tune shift with amplitude is a pendulum. In accelerator physics, both the transverse and the longitudinal dynamics show tune shift with amplitude. A simple model of the transverse dynamics is of an oscillator with a single sextupole, it is referred to as the Hénon map. Another model for this case is the Standard Map. An important example is the typical case of distributed
Something to Answer For certain he is really dead, then apparently actually does so. At the end of the novel, though it is uncertain how much of what was related actually took place or how much was a fever or drunken dream, Townrow comes to believe that a citizen is not responsible for the morality of his government and has only himself and his own actions to answer for. Something to Answer For Something to Answer For is a 1968 novel by the English writer P. H. Newby. Its chief claim to fame is that in 1969 it won the inaugural Booker Prize, which
