We consider a random walk model that takes into account the velocity distribution of random walkers. Random motion with alternating velocities is inherent to various physical and biological systems. Moreover, the velocity distribution is often the first characteristic that is experimentally accessible. Here, we derive transport equations describing the dispersal process in the model and solve t...

To study the decision process during rating tasks, PC cursor trajectories were recorded and analyzed. The trajectories were often successions of rapid saccadic-like movements that are called strokes in this paper. The analysis of strokes revealed that the distribution of strokes differed across tasks as a function of task difficulty. A simple number matching task elicited fewer strokes, shorter...

Consider sequential packing of unit volume balls in a large cube, in any dimension and with Poisson input. We show after suitable rescaling that the spatial distribution of packed balls tends to that of a Gaussian field in the thermodynamic limit. The results cover related applied models, including ballistic deposition and spatial birth-growth models.

We investigate scattering through chaotic ballistic quantum dots in the Coulomb-blockade regime. Focusing on the scattering phase, we show that large universal sequences emerge in the short wavelength limit, where phase lapses of π systematically occur between two consecutive resonances. Our results are corroborated by numerics and are in qualitative agreement with existing experiments.

The exponential rise in the density of silicon CMOS transistors has now reached a limit and threatening to end the microelectronics revolution. To tackle this difficulty, group III–V compound semiconductors due to their outstanding electron transport properties and high mobility are very actively being researched as channel materials for future highly scaled CMOS devices. In this paper, we have...

The compression after high-velocity impact (CAI) behavior of pseudo-elastic shape memory alloy (PE-SMA) embedded glass/epoxy composite laminates manufactured via vacuum-assisted resin infusion (VARI) technique was investigated experimentally. High-velocity tests were performed on the composites using an in-house build gas-gun set-up at four different velocities (70, 85, 95, and 105 m/s). To elu...

Two-dimensional materials with strong bandstructure anisotropy such as black phosphorus BP have been identified attractive candidates for logic application due to their potential high carrier velocity and large density-of-states. However, perfectly aligning the source-to-drain axis desired crystal orientation remains an experimental challenge. In this paper, we use advanced quantum transport ap...

Abstract Composite armors are widely used in the protection of human body and special vehicles due to their excellent ballistic performance. In this study, impact response SiC ceramics/Ultra-High Molecular Weight Polyethylene (UHMWPE) composite plate subjected fragment simulating projectiles (FSP) is investigated numerically. The influences head shape ceramic column position on failure modes, l...

Two research groups have measured turbulent velocity statistics in superfluid helium using different techniques. The results were in conflict: one experiment revealed Gaussian distributions (as observed in ordinary turbulence), the other experiment determined power laws. To solve the apparent puzzle, we numerically model quantum turbulence as a tangle of vortex filaments, and conclude that ther...

Abstract Self-propelled particulate systems manifest certain collective behavior of living matter, which have been the subject intense research over past decades. One elegant methods for realizing such active motions is by means custom synthesized Janus particles suspended in a catalytic medium that can be triggered upon illumination ultraviolet light. In this work, evolution particle dynamics ...
