The collisionless time evolution of zonal flows in stellarator systems is investigated. An analytical solution of the kinetic and quasineutrality equations describing the residual zonal flow is derived for arbitrary three-dimensional systems without approximations in the magnetic geometry. The theory allows for an arbitrary number of particle species. It has been found that in stellarators the ...

Electric potentials are generated across the Cornea and Retina of the eyes as a result of the movement of eyeballs within the conductive environment of the skull. This is referred to as the Cornea-Retinal Potential (CRP) and is the source of the Electrooculogram (EOG) signal. Since the occurrence of DC drifts and numerous artifacts along with power-line interference had made the EOG signal quit...

Viral particle binding to plasma membrane receptors elicits virus motions, recruits signaling proteins, and triggers membrane bending and fission, finally resulting in endocytic virus uptake. Here we analyze how human adenovirus engages its receptor coxsackievirus adenovirus receptor (CAR) and coreceptor αv integrin to move on the plasma membrane. Virus binding to CAR through fiber knobs gave r...

In this work we investigate the issue of logarithmic drifts in position level sets solutions monostable reaction–diffusion equations, with respect to traveling front minimal speed. On one hand, it is a celebrated result Bramson that such drift occurs when reaction KPP (or sublinear) type. other also known phenomenon disappears speed nonlinearly determined. However, some equations fall neither t...

In natural vision, continuously changing input is generated by fast saccadic eye movements and slow drifts. We analyzed effects of fixational saccades, voluntary saccades, and drifts on the activity of macaque V1 neurons. Effects of fixational saccades and small voluntary saccades were equivalent. In the presence of a near-optimal stimulus, separate populations of neurons fired transient bursts...

This paper presents a numerical study on the response of the unsaturated zone (UZ) system of Yucca Mountain to heat generated from decaying radioactive wastes emplaced at the proposed repository. The modeling study is based on the current thermal-hydrological (TH) mountain-scale model, which uses a locally refined 2D north-south cross-section and dual-permeability numerical approach. The model ...
