Backward correlations and dynamic heterogeneities: a computer study of ion dynamics

open access: yes, 2002
We analyse the correlated back and forth dynamics and dynamic heterogeneities, i.e. the presence of fast and slow ions, for a lithium metasilicate system via computer simulations.

Rheological Master Curves of Crystallizing Polymer Mixtures

open access: yesApplied Rheology, 2006
We present a simple methodology for extending linear viscoelastic measurements of crystallizing polymers to the high-frequency regime, where usually crystallization kinetics represents an obstacle. The idea is to perform rapid quenches, below the melting

Molecular Dynamics Computer Simulation of the Dynamics of Supercooled Silica

open access: yes, 1997
We present the results of a large scale computer simulation of supercooled silica. We find that at high temperatures the diffusion constants show a non-Arrhenius temperature dependence whereas at low temperature this dependence is also compatible with an

Intermittent electron density and temperature fluctuations and associated fluxes in the Alcator C-Mod scrape-off layer [PDF]

open access: yes, 2018
The Alcator C-Mod mirror Langmuir probe system has been used to sample data time series of fluctuating plasma parameters in the outboard mid-plane far scrape-off layer. We present a statistical analysis of one second long time series of electron density,

Formulation of non-linear viscoelastic–viscoplastic constitutive equation for polyamide 6 resin

open access: yesHeliyon, 2021
In this study, a non-linear viscoelastic–viscoplastic constitutive equation for polyamide 6 (PA6) is formulated and a new model is suggested for the viscoplastic part of the equation.

Generation of a superposition of multiple mesoscopic states of radiation in a resonant cavity [PDF]

open access: yesPhys. Rev. A 71, 043823 (2005), 2004
Using resonant interaction between atoms and the field in a high quality cavity, we show how to generate a superposition of many mesoscopic states of the field. We study the quasi-probability distributions and demonstrate the nonclassicality of the superposition in terms of the zeroes of the Q-function as well as the negativity of the Wigner function ...

Biorthogonal resource theory of genuine quantum superposition [PDF]

open access: yesarXiv, 2022
The phenomenon of quantum superposition manifests in two distinct ways: it either spreads out across non-orthogonal basis states or remains concealed within their overlaps. Despite its profound implications, the resource theory of superposition often neglects the quantum superposition residing within these overlaps.

Damage detections in nonlinear vibrating thermally loaded plates [PDF]

open access: yes, 2009
In this work, geometrically nonlinear vibrations of fully clamped rectangular plates subjected to thermal changesare used to study the sensitivity of some vibration response parameters to the presence of damage and elevated temperature. The geometrically

DMA Master Curves for Long-Term Life Prediction of Epoxy Resins and Composites Using Time Temperature Superposition [PDF]

open access: yesMaterials Research
This study presents the results of constructing the master curve through dynamic mechanical analysis (DMA) of unidirectional composites made of glass fiber and epoxy resins of classes F and H to evaluate the thermal stability and durability of these ...
