Glassy Aging with Modified Kohlrausch-Williams-Watts Form [PDF]

, 2007
In this report we address the question whether aging in the non equilibrium glassy state is controlled by the equilibrium alpha-relaxation process which occur at temperatures above Tg. Recently Lunkenheimer et. al. [Phys. Rev. Lett.

Optimum Pump Pulse Duration for X-Ray Ar-Plasma Lasing

Photonics, 2015
In plasma-driven X-ray lasers, it is critical to optimize the duration and time delay between pump pulses. In this study, we have done parametric simulations in order to systematically investigate the optimum time configuration of pump pulses.

A Substitutive Coefficients Network for the Modelling of Thermal Systems: A Mono-Zone Building Case Study

Energies, 2021
A modelling approach based on the Substitutive Coefficients Network (SCN) is developed to predict the thermal behavior of a system in the dynamic state-space, without requiring knowledge of the thermal mass.

Gravitational collapse: A case for thermal relaxation [PDF]

, 1997
Two relativistic models for collapsing spheres at different stages of evolution, which include pre-relaxation processes, are presented. The influence of relaxation time on the outcome of evolution in both cases is exhibited and established.

Cerebral Microstructural Alterations in Patients With Early Parkinson’s Disease Detected With Quantitative Magnetic Resonance Measurements

Frontiers in Aging Neuroscience, 2021
Objective: Parkinson’s disease (PD) is the second most common neurodegenerative disease in the elderly. In early stages of PD, patients typically display normal brain magnet resonance imaging (MRI) in routine screening.

Slow relaxation in the two dimensional electron plasma under the strong magnetic field [PDF]

, 2006
We study slow relaxation processes in the point vortex model for the two-dimensional pure electron plasma under the strong magnetic field. By numerical simulations, it is shown that, from an initial state, the system undergoes the fast relaxation to a ...
