Kinks are a structural feature of alpha-helices and many are known to have functional roles. Kinks have previously tended to be defined in a binary fashion. In this paper we have deliberately moved towards defining them on a continuum, which given the unimodal distribution of kink angles is a better description. From this perspective, we examine the conservation of kinks in proteins. We find th...

We use experiments and molecular dynamics simulations of vertically oscillated granular layers to study horizontal particle segregation induced by a kink (a boundary between domains oscillating out of phase). Counterrotating convection rolls carry the larger particles in a bidisperse layer along the granular surface to a kink, where they become trapped. The convection originates from avalanches...

We discuss the mechanism causing the ‘kink’ in the charge radius isotope shift at the N = 126 shell closure. The occupation of the 1i11/2 neutron orbital is the decisive factor for reproducing the experimentally observed kink. We investigate whether this orbital is occupied or not by different Skyrme effective interactions as neutrons are added above the shell closure. Our results demonstrate t...

This paper explores how the impact of retirement on self-assessed illness varies spatially across the UK. Curves of age-specific limiting long term illness rates reveal a 'retirement kink'-where the rise in illness rates with age slows or declines at retirement age indicating possible health improvement after retirement. The kink is negligible in the affluent South East and most prominent in th...

One-loop corrections to kink masses in a family of (1+1)-dimensional field theoretical models with two scalar fields are computed. A generalized DHN formula applicable to reflection and reflectionless potentials is obtained. It is thus shown how half-bound states arising in the spectrum of the second order fluctuation operator around TK1 kinks and the vacuum play a central rôle in the computati...

Unconventional sensual, erotic, and sexual behaviors (herein referred to as kink behaviors) investigated by academia are based largely on clinical and criminal cases, and most published, peer-reviewed, quantitative research on these behaviors is based almost exclusively on male participants. For this study, information was collected and analyzed from 1580 female participants recruited from the ...

A semiclassical 2D ensemble Monte Carlo simulator is used to perform a physical microscopic analysis of kink effect in InAs/AlSb High Electron Mobility Transistors (HEMTs). Due to the small bandgap of InAs, these devices are very susceptible to suffer impact ionization processes, with the subsequent hole transport through the structure, both implicated in the kink effect. The results indicate t...

In this paper, kink scattering in the dimensional reduction of bosonic sector a one-parameter family generalized Wess-Zumino models with three vacuum points is discussed. The value model parameter determines specific location vacua. influence arrangements (evolving from collinear vacua to placed at vertices an equilateral triangle) on investigated. Two different regimes can be distinguished: fi...

We predict theoretically that surface of an optical lattice imprinted in defocusing nonlinear media can support shock, or kink waves. Such new surface waves contain a modulationally stable pedestal and are strongly localized at the edge of the optical lattice due to Bragg-type reflection. The kink steepness and localization degree can be controlled by the lattice depth. We found two types of ki...

In this work we review the efforts that have been done to study the excitation of the standing fast kink body mode in coronal loops. We mainly focus on the time-dependent problem, which is appropriate to describe flare or CME induced kink oscillations. The analytical and numerical studies in slab and cylindrical loop geometries are reviewed. We discuss the results from very simple one-dimension...
