ABSTRACT Very long baseline interferometry radio images recently proved to be essential in breaking the degeneracy ejecta model for neutron star merger GW170817. We discuss properties of synthetic jet afterglows by using semi-analytical models laterally spreading or non-spreading jets. The image centroid initially moves away from explosion point sky with apparent superluminal velocity. After re...

Seismically active areas are vulnerable to liquefaction, and the influence of liquefaction on pile foundations is very severe. Study pile-supported buildings in liquefiable soils requires consideration soil-pile interaction evaluation resulting from movement soil surrounding pile. This paper presents results three-dimensional finite difference analyses conducted understand effect seismic perfor...

We demonstrate that the efficiency droop phenomenon in multiple quantum well InGaN/GaN light-emitting diodes (LEDs) may be connected to the current crowding effect. A numerical model of internal quantum efficiency calculation is presented that takes into account nonuniform lateral carrier injection in the active region. Based on this model, we examine the effect of current crowding on the effic...

In the mammalian primary visual cortex (V1), lateral spreading of excitatory potentials is believed to be involved in spatial integrative functions, but the underlying cortical mechanism is not well understood. Visually-evoked population-level responses have been shown to propagate beyond the V1 initial activation site in mouse, similar to higher mammals. Visually-evoked responses are, however,...
