Anomalous width variation of rarefactive ion acoustic solitary waves in the context of auroral plasmas [PDF]

Nonlinear Processes in Geophysics, 2004
The presence of dynamic, large amplitude solitary waves in the auroral regions of space is well known. Since their velocities are of the order of the ion acoustic speed, they may well be considered as being generated from the nonlinear evolution of ion ...

Research Progress on Mechanical Characteristics of Vertical Cylinders under Internal Solitary Waves

Renmin Zhujiang, 2022
Internal solitary waves represent a common physical phenomenon in water bodies such as oceans,coasts,and estuaries.They are induced by external disturbances on a pycnocline in a stably stratified water body,and the shear flow excited during their ...

Exploration of Physical Properties of Sodium‐Based Perovskite Hydrides ANaH3 (A = Hf, Nb, Pd, Ru) for Hydrogen Storage Applications: First Principles Study

Advanced Physics Research, EarlyView.
First‐principles calculations reveal that ANaH3 (where A = Hf, Nb, Pd, Ru) perovskite hydrides combine structural stability, favorable electronic properties, and low hydrogen desorption temperatures (280–369 K). Strong metal–hydrogen interactions and reversible hydrogen storage characteristics identify these materials as promising candidates for ...

New Types of Nonlinear Waves and Bifurcation Phenomena in Schamel-Korteweg-de Vries Equation

Abstract and Applied Analysis, 2013
We study the nonlinear waves described by Schamel-Korteweg-de Vries equation ut+au1/2+buux+δuxxx=0. Two new types of nonlinear waves called compacton-like waves and kink-like waves are displayed.

Are there morpho‐acoustic patterns of adaptation in nonhuman primate ears? Testing the role of ecology and habitat in shaping ear morphology and function

The Anatomical Record, EarlyView.
Abstract Analysis of the variation in the bony structures of the inner and middle ear provides critical insights into functional morphology, as well as adaptive morphology across primates. In this study, we investigated whether ear morphology patterns are related to the ecological characteristics of species and their habitats to test two acoustic ...
