Well-posedness and general decay of a nonlinear damping porous-elastic system with infinite memory

, 2020
In the present work, we consider a one-dimensional porous-elastic system with infinite memory and a nonlinear damping term. We establish the well-posedness of the system using semigroup theory and show the general decay for the case of nonequal speeds of

On the decay of correlations in the generalized spherical model

Journal of Physics A: Mathematical and General, 1999
Summary: We point out that the generalized spherical model, as a limit of the isotropic \(n\)-vector model, inherits a natural separation into longitudinal and transverse spin projections with respect to the direction of the external field (or spontaneous magnetization), which are distributed in the limit as two independent Gaussian scalar spin systems

Decay of Conservation Laws and Their Generating Functions

Acta Applicandae Mathematicae, 1995
The paper deals with decay velocity of the quantities which are conserved in absense of dissipation. The decay velocity (or the ``balance law'') may be found explicitly using the generating function of the conservation law. The general approach is illustrated by a certain system of MHD equations for incompressible magnetofluids.

New general decay results for a Moore–Gibson–Thompson equation with memory

Applicable Analysis, 2020
In this paper, we consider the Moore–Gibson–Thompson equation with a memory term in the subcritical case, which arises in high-frequency ultrasound applications accounting for thermal flux and molecular relaxation times.

General decay synchronisation of discontinuous fuzzy neural networks with discrete and distributed time-delays via nonlinear feedback control

International Journal of Systems Science, 2020
This paper aims to provide a new framework to study the general decay synchronisation analysis of a class of fuzzy neural networks with discontinuous activations, discrete and distributed time-delays.

General Decay Stability for Nonautonomous Neutral Stochastic Systems With Time-Varying Delays and Markovian Switching

IEEE Transactions on Cybernetics, 2020
A new type of asymptotic stability for nonlinear hybrid neutral stochastic systems with constant delays was investigated recently, where the criteria depended on the delays’ sizes.

Decaying grid-generated turbulence in a rotating tank [PDF]

Physics of Fluids, 2005
The decay of initially three-dimensional homogeneous turbulence in a rotating frame is experimentally investigated. Turbulence is generated by rapidly towing a grid in a rotating water tank, and the velocity field in a plane perpendicular to the rotation axis is measured by means of particle image velocimetry. During the decay, strong cyclonic coherent

The effect of fibrin(ogen) on thrombin generation and decay

Thrombosis and Haemostasis, 2014
SummaryDefibrination causes a ~30% decrease of thrombin generation (TG) which can be restored by adding native fibrinogen in its original concentration (3 mg/ml). The fibrinogen variant γA/γ′, which binds thrombin with high affinity, is over four times more efficient in this respect than the more common γA/γA form.

Rare Decays and the Fourth Generation

Annals of the New York Academy of Sciences, 1989
Rare decays are quite sensitive1 to physics beyond the Standard Model (SM), due to the effects of virtual, new, heavy particles (i.e., a fourth generation, SUSY, charged Higgs, E6 exotic fermions,…). These new contributions can either enhance or suppress (sometimes quite substantially) the rates for rare processes compared to the corresponding SM ...
