Resonant Scattering of Gravitational Waves with Electromagnetic Waves

Chinese Physics Letters, 2023
A certain class of exact solutions of Einstein Maxwell spacetime in general relativity is discussed to demonstrate that at the level of theory, when certain parametric resonance condition is met, the interaction of electromagnetic field with a gravitational wave will display certain Lyapunov instability and lead to exponential amplification of a ...

Collapse of wave functions in Schrödinger’s wave mechanics

Scientific Reports
We show that inelastic scattering in a short-range potential leads to a collapse of the wave function within standard evolution through the Schrödinger equation, whereas elastic scattering will not collapse the wave function.

Numerical simulation study of lower hybrid wave scattering full-wave solution in scrap-off layer

He jishu
BackgroundLower hybrid current drive (LHCD) is one of the main auxiliary heating and current driving methods for Tokamak, and studies have shown that the boundary parasitics effect of lower hybrid (LH) wave in scrap-off layer (SOL) significantly ...

Pore-scale modeling of pore structure effects on P-wave scattering attenuation in dry rocks.

PLoS ONE, 2015
Underground rocks usually have complex pore system with a variety of pore types and a wide range of pore size. The effects of pore structure on elastic wave attenuation cannot be neglected.

A novel method for investigation of acoustic and elastic wave phenomena using numerical experiments

Theoretical and Applied Mechanics Letters, 2020
The emergence of new types of composite materials, the depletion of existing hydrocarbon deposits, and the increase in the speed of trains require the development of new research methods based on wave scattering.

Time-Dependent Modelling of the Wave-Induced Vibration of Ice Shelves

Journal of Marine Science and Engineering, 2023
This work presents an investigation of ice shelf vibration using a model based on shallow water approximation. The study focused on the effect of changes in the draft on the vibration of the ice shelf and presents both time-domain and frequency-domain ...

Wave scattering from self-affine surfaces

, 1999
Electromagnetic wave scattering from a perfectly reflecting self-affine surface is considered. Within the framework of the Kirchhoff approximation, we show that the scattering cross section can be exactly written as a function of the scattering angle via

Inverse wave scattering with discontinuous wave speed [PDF]

Journal of Mathematical Physics, 1995
The inverse scattering problem on the line is studied for the generalized Schrödinger equation (d2ψ/dx2)+k2H(x)2ψ=Q(x)ψ, where H(x) is a positive, piecewise continuous function with positive limits H± as x → ±∞. This equation, in the frequency domain, describes the wave propagation in a nonhomogeneous medium, where Q(x) is the restoring force and 1/H(x)

Discovery and Targeted Proteomic Studies Reveal Striatal Markers Validated for Huntington's Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Clinical trials for Huntington's disease (HD) enrolling persons before clinical motor diagnosis (CMD) lack validated biomarkers. This study aimed to conduct an unbiased discovery analysis and a targeted examination of proteomic biomarkers scrutinized by clinical validation. Methods Cerebrospinal fluid was obtained from PREDICT‐HD and
