The dynamic density functional (DDF) theory and standard Brownian dynamics simulations (BDS) are used to study the drifting effects of a colloidal particle in a polymer solution, both for ideal and interacting polymers. The structure of the stationary density distributions and the total induced current are analyzed for different drifting rates. We find good agreement with the BDS, which gives s...

Experiments with drifting gratings are widespread in the study of neurons in the retina and dorsal lateral geniculate nucleus (dLGN). As an alternative to descriptive modeling based on the di!erence-of-Gaussians model, we show how mechanistic models for the retinogeniculate circuitry can be tested against drifting-grating data. As an example of this approach we (i) derive mechanistic expression...

Benchmark solutions for fully nonlinear anelastic compressible convection and dynamo action in a rotating spherical shell are proposed. Three benchmarks are specified. The first is a purely hydrodynamic case, which is steady in a uniformly drifting frame. The second is a self-excited saturated dynamo solution, also steady in a drifting frame. The third is again a self-excited dynamo but is unst...

We report experimental and theoretical results on the conductive regime of electroconvection in hybrid aligned nematics. The drifting oblique/normal rolls below/above the Lifshitz frequency are observed at the onset of electroconvection under a.c. voltage. The experimental data on the threshold voltage, wavelength, oblique angle and drift period of the rolls as function of a.c. frequency are in...

Contrast energy thresholds were measured for discriminating the direction of a drifting sinusoidal grating multiplied by an independently drifting space-time Gaussian (a generalized Gabor). We argue that the stimulus with the lowest contrast energy threshold identifies the receptive field of the most efficient linear motion filter. This optimal motion stimulus is found to be at 3 c/deg and 5 Hz...

Abstract NEWAGE is the experiment of direction-sensitive dark matter search using low pressure gaseous TPC with micro pattern strip readout ( μ -PIC). It allows to measure distribution angles WIMP-nuclear recoil by track reconstruction, and it a positive signature matter. In recent years, large size (∼1 m 3 ) filled SF 6 gas, which so called “negative-ion gas”, under development. A negative ion...

We introduce a novel fluid manipulation technique named "microfluidic drifting" to enable three-dimensional (3D) hydrodynamic focusing with a simple single-layer planar microfluidic device.

We have investigated the evolution of a system sparking discharges in inner acceleration region (IAR) above pulsar polar cap. The surface cap is heated to temperatures around $10^6$ K and forms partially screened gap (PSG) due thermionic emission positively charged ions from stellar surface. sparks lag behind co-rotation speed during their lifetimes variable $E$x$B$ drift. In PSG arise location...
