Abstract Recent studies have revealed the complex structure of nerve signals in axons. Besides electrical signal, mechanical and thermal effects are also detected many experimental studies. In this paper, mathematical models heat generation analysed within framework a general model derived earlier by authors. The main mechanisms seemingly Joule heating endo- exothermic reactions. concept intern...

A model is developed for quantifying shear-band propagation in bulk metallic glasses. This model is written in terms of the stress, temperature, and band propagation speed. The model quantifies the shear-band length, width, and speed, as well as the direction of propagation and the magnitude of displacement across the band. Corresponding author: B.J.

This study describes a methodology and gives an example of a simplified analysis to determine the steady propagation speed of a projectile fired into a gaseous mixture of fuel and oxidizer. For tractability, the steady supersonic flow of an inviscid calorically perfect ideal reacting gas with high activation energy over a symmetric double wedge, unconfined by a cowl, is considered. A search of ...

Huygens' principle (HP) is understood as a universal principle governing not only the propagation of light, but also of acoustic waves, heat and matter di!usion, SchroK dinger's matter waves, random walks, and many more. According to Hadamard's rigorous de"nition, HP comprehends the principle of action-by-proximity (cf. Faraday's "eld theory, etc.) and the superposition of secondary wavelets (H...
