Density Scaling and Dynamic Correlations in Viscous Liquids [PDF]

, 2009
We use a recently proposed method [Berthier L.; Biroli G.; Bouchaud J.P.; Cipelletti L.; El Masri D.; L'Hote D.; Ladieu F.; Pierno M. Science 2005, 310, 1797.] to obtain an approximation to the 4-point dynamic correlation function from derivatives of the

Spin dynamics in lightly doped La 2-x Sr x CuO 4 : Relaxation function within the t-J model [PDF]

, 2004
The relaxation function theory of doped two-dimensional $S=1∕2$ Heisenberg antiferromagnetic (AF) systems in the paramagnetic state is presented taking into account the hole subsystem as well as both the electron and AF correlations.

Estimation of phonon relaxation time for silicon by means of using the velocity autocorrelation function of atoms in molecular dynamics [PDF]

Bulletin of the Polish Academy of Sciences: Technical Sciences, 2019
Results of the ab initio molecular dynamics calculations of silicon crystals are presented by means of analysis of the velocity autocorrelation function and determination of mean phonon relaxation time.

Relaxation processes and entropic traps in the Backgammon model [PDF]

, 1996
We examine the density-density correlation function in a model recently proposed to study the effect of entropy barriers in glassy dynamics. We find that the relaxation proceeds in two steps with a fast beta process followed by alpha relaxation.

NONMONOTONE CONVERGENCE AND RELAXING FUNCTIONS [PDF]

International Journal of Pure and Apllied Mathematics, 2013
In the minimization of real valued functions, Newton's algorithm is often combined with a line search method. Grippo et al (SIAM J. Numer. Anal., Vol. 23, No. 4) first suggested a nonmonotone stepsize selection rule based on the maximum of a fixed set of previous function values. In this pa- per we introduce the notion of relaxing functions and suggest

General and optimal decay rates for a system of wave equations with damping and a coupled source term

AIMS Mathematics
In this article, we aim to investigate the decay characteristics of a system consisting of two viscoelastic wave equations with Dirichlet boundary conditions, where the dispersion term and nonlinear weak damping term are taken into account.

Inhibition of Endoplasmic Reticulum Stress Improves Acetylcholine-Mediated Relaxation in the Aorta of Type-2 Diabetic Rats

Molecules, 2022
Endoplasmic reticulum (ER) stress contributes to insulin resistance and macro- and microvascular complications associated with diabetes. This study aimed to evaluate the effect of ER stress inhibition on endothelial function in the aorta of type-2 ...
