A one-step optimal energy decay formula for indirectly nonlinearly damped hyperbolic systems coupled by velocities [PDF]
arXiv, 2015 In this paper, we consider the energy decay of a damped hyperbolic system of wave-wave type which is coupled through the velocities. We are interested in the asymptotic properties of the solutions of this system in the case of indirect nonlinear damping, i.e. when only one equation is directly damped by a nonlinear damping.

Nonlinear Landau damping in the ionosphere [PDF]
Journal of Geophysical Research: Space Physics, 1979 A model is presented to explain the nonresonant waves which give rise to the diffuse resonance observed near 3/2 fH by the Alouette and Isis topside sounders, where fH is the ambient electron cyclotron frequency. These waves are the result of plasma wave instabilities driven by anisotropic electron velocity distributions initiated by the high‐power ...

Ergodic results for the stochastic nonlinear Schrödinger equation with large damping [PDF]
arXiv, 2022 We study the nonlinear Schr\"odinger equation with linear damping, i.e. a zero order dissipation, and additive noise. Working in $R^d$ with d = 2 or d = 3, we prove the uniqueness of the invariant measure when the damping coefficient is sufficiently large.

Reprogrammable Mechanical Metamaterials via Passive and Active Magnetic Interactions
Advanced Materials, EarlyView.The combination of flexible matrices with embedded hard‐magnetic nodes enables metastructures with reprogrammable mechanical properties, even in the absence of external magnetic fields. The evolving interaction between nodes during structural deformation allows mechanical tunability under quasi‐static and dynamic loading, and bistable transitions. This

Effect of the viscous damping on the seismic response of Low-rise RC frame building
Revista Facultad de Ingeniería Universidad de Antioquia, 2020 The equivalent viscous damping is a key parameter in the prediction of the maximum nonlinear response. Damping constitutes a major source of uncertainty in dynamic analysis. This paper studies the effect of using viscous damping, on the reduction of the

On the $L^{2}$-critical nonlinear Schrödinger Equation with a nonlinear damping [PDF]
arXiv, 2012 We consider the Cauchy problem for the $L^{2}$-critical nonlinear Schr\"{o}dinger equation with a nonlinear damping. According to the power of the damping term, we prove the global existence or the existence of finite time blowup dynamics with the log-log blow-up speed for $\|\nabla u(t)\|_{L^2}$.

Blowup for the nonlinear Schrödinger equation with an inhomogeneous damping term in the $L^2$ critical case [PDF]
, 2014 We consider the nonlinear Schr\"odinger equation with $L^2$-critical exponent and an inhomogeneous damping term. By using the tools developed by Merle and Raphael, we prove the existence of blowup phenomena in the energy space $H^1(\mathbb{R})$.
