Coherent percepts emerge from the accurate combination of inputs from the different sensory systems. There is an ongoing debate about the neurophysiological mechanisms of crossmodal interactions in the brain, and it has been proposed that transient synchronization of neurons might be of central importance. Oscillatory activity in lower frequency ranges (<30Hz) has been implicated in mediating l...

We describe non-standard techniques for optical studies of electrocon-vection structures in nematics. The time-resolved textures in the high frequency oscillatory regime are analyzed and compared with results of optical simulations. Conclusions on the relation between director pattern and optical texture are drawn. Using an additional phase plate in the optical setup , we monitor director twist...

A cell population in which cells are allowed to enter a quiescent (nonproliferating) phase is analyzed using a stochastic approach. A general branching process is used to model the population which, under very mild conditions, exhibits balanced exponential growth. A formula is given for the asymptotic fraction of quiescent cells, and a numerical example illustrates how convergence toward the as...

The purpose of this work is to study the effect of oscillatory MHD blood flow in stenosed artery. The analytical and numerical results are obtained for oscillatory MHD blood flow, which is assumed to be a Newtonian fluid. It was also assumed that the surface roughness is of cosine shaped and the maximum height of roughness is negligible, compared with the radius of un-constricted tube. The flui...

Abstract We model the Parker instability in vertically stratified isothermal gas using non-ideal MHD three-dimensional simulations. Rotation, especially differential, more strongly and diversely affects nonlinear state than linear stage (where we confirm most important conclusions of analytical models), stronger any analyses predict. Steady magnetic fields are cosmic ray energy density higher c...

We check the robustness of a recently proposed dynamical model associative Pavlovian learning that extends Rescorla-Wagner (RW) in natural way and predicts progressively damped oscillations response subjects. Using data two experiments, we compare oscillatory (DOM) with an made superposition RW curve oscillations. Not only do clearly show pattern, but they also favor DOM over added oscillation ...
