Thermal transport and quasi-normal modes in Gauss–Bonnet-axions theory

open access: yesPhysics Letters B, 2017
We obtain the black brane solution in arbitrary dimensional Gauss–Bonnet-axions (GBA) gravity theory. And then the thermal conductivity of the boundary theory dual to this neutral black brane is explored.

Quasi-neutral limit for a viscous capillary model of plasma

open access: yesAnnales de l'Institut Henri Poincaré C, Analyse non linéaire, 2005
The purpose of this work is to study the quasi-neutral limit of a viscous capillary model of plasma expressed as a so-called Navier–Stokes–Poisson–Korteweg model. The existence of global weak solutions for a given Debye length λ is obtained in a periodic box domain

Solvolysis kinetic study and direct spectrofluorimetric analysis of the fungicide benomyl in natural waters

open access: yesMacedonian Journal of Chemistry and Chemical Engineering, 2014
A direct spectrofluorimetric method for the quantitative analysis of benomyl in natural waters is described. Benomyl is an instable, fluorescent fungicide that mainly decomposes into carbendazim and n-butyl-isocyanate in organic and aqueous solutions ...

Electrodeposition and Characterization of W-rich NiW Alloys from Citrate Electrolyte

open access: yesInternational Journal of Electrochemical Science, 2016
The electrodeposition of NiW alloys from citrate electrolyte was studied in an effort to evaluate the effect of applied potential and solution pH on the composition limit and the properties of the deposits.

Thin and superthin ion current sheets. Quasi-adiabatic and nonadiabatic models [PDF]

open access: yesNonlinear Processes in Geophysics, 2000
Thin anisotropic current sheets (CSs) are phenomena of the general occurrence in the magnetospheric tail. We develop an analytical theory of the self-consistent thin CSs.

An asymptotically stable discretization for the Euler–Poisson system in the quasi-neutral limit

open access: yesComptes Rendus. Mathématique, 2005
We are interested in the modeling of a plasma in the quasi-neutral limit using the Euler–Poisson system. When this system is discretized with a standard numerical scheme, it is subject to a severe numerical constraint related to the quasi-neutrality of the plasma.

Molecular Dynamics Studies of Shape Memory Polymers: From Bead–Spring Models to Atomistic Simulations

open access: yesAdvanced Engineering Materials, EarlyView.
Coarse‐grained (left) and atomistic (right) models of the shape memory polymer ESTANE ETE 75DT3 are shown schematically. The two representations bridge molecular detail and mesoscopic description. Both models capture shape memory behavior, linking segmental mobility and conformational relaxation of anisotropic chains to macroscopic recovery, and ...

Quantum quasi-neutral limits and isothermal Euler equations

open access: yesNonlinearity
Abstract We provide a rigorous justification of the semiclassical quasi-neutral and the quantum many-body limits to the isothermal Euler equations. We consider the nonlinear Schrödinger–Poisson–Boltzmann system under a quasi-neutral scaling and establish the convergence of its solutions to the isothermal Euler equations.
