Chaotic scattering in solitary wave interactions: A singular iterated-map description

open access: yes, 2007
We derive a family of singular iterated maps--closely related to Poincare maps--that describe chaotic interactions between colliding solitary waves. The chaotic behavior of such solitary wave collisions depends on the transfer of energy to a secondary ...

Numerical evaluation of equivalence ratio measurement using OH* and CH* chemiluminescence in premixed and non-premixed methane-air flames [PDF]

open access: yes, 2008
We provide the existence and asymptotic description of solitary wave solutions to a class of modified Green–Naghdi systems, modeling the propagation of long surface or internal waves. This class was recently proposed by Duchêne et al. (Stud Appl Math 137:

Making teaching an attractive profession: What are the challenges and opportunities for minority ethnic teachers in England?

open access: yesBritish Educational Research Journal, EarlyView.
Abstract This paper explores the challenges and opportunities surrounding the recruitment and retention of minority ethnic teachers in England. Drawing on interview data from 33 teachers and school leaders of diverse ethnic backgrounds, it investigates whether racialised barriers identified in earlier research have shifted in the current context of ...

Two-dimensional numerical simulations of shoaling internal solitary waves at the ASIAEX site in the South China Sea [PDF]

open access: yesNonlinear Processes in Geophysics, 2015
The interaction of barotropic tides with Luzon Strait topography generates some of the world's largest internal solitary waves which eventually shoal and dissipate on the western side of the northern South China Sea. Two-dimensional numerical simulations

Stability of Spatial Optical Solitons [PDF]

open access: yes, 2000
We present a brief overview of the basic concepts of the soliton stability theory and discuss some characteristic examples of the instability-induced soliton dynamics, in application to spatial optical solitons described by the NLS-type nonlinear models ...

Superior CO2 Conversion Performance by Er‐Doped BiOCl Nanosheets Through Synergistic Photocatalytic Memory Effect and Er‐Doping

open access: yesCarbon Energy, EarlyView.
Er‐doping and the photocatalytic memory effect through visible‐light irradiation synergistically reconstruct internal electronic states of ultrathin Er‐doped BiOCl nanosheets and generate stable oxygen vacancies. Light absorption, charge carrier separation, and CO2 adsorption capability are subsequently enhanced, leading to a significant increase in ...

High‐Energy‐Density Redox Flow Batteries: Mechanisms, Design Strategies, and Recent Progress

open access: yesChemistry – A European Journal, EarlyView.
ABSTRACT The inherent intermittency of energy sources such as solar and wind power hinders the transition to renewable energy, necessitating advanced energy storage solutions. Enhancing energy density is crucial for lowering system costs and enabling large‐scale deployment.

Action of strong internal solitary waves on surface waves [PDF]

open access: yesJournal of Geophysical Research: Oceans, 2002
Transformation of gravity capillary surface waves on the current created by a large‐amplitude internal wave (IW) is considered. The trajectories of surface wave packets in a domain of coordinate and wave number are calculated for different IW amplitudes.

Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

open access: yesDeep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

Strong Nonradiative Recombination Induced by Pronounced Lone‐Pair Electron Expression Following Deprotonation in Aziridinium Lead Iodide Perovskites

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The transition from linear to cyclic organic cations promotes deprotonation and activates VH(N) defects with pronounced lone‐pair electron activity, thereby inducing severe local distortions and highly efficient nonradiative recombination centers. This work unveils a direct structure–defect–performance correlation and proposes design strategies for the
