Unified gas-kinetic wave-particle methods IV: multi-species gas mixture and plasma transport

open access: yesAdvances in Aerodynamics, 2021
In this paper, we extend the unified gas-kinetic wave-particle (UGKWP) methods to the multi-species gas mixture and multiscale plasma transport. The construction of the scheme is based on the direct modeling on the mesh size and time step scales, and the

Fragmentation of AdS5-Kerr black holes

open access: yesNuclear Physics B, 2022
Black hole spacetimes asymptotic to five-dimensional anti-de Sitter spacetime are of great interest in connection with the string-gauge duality. In the rotating case, such black holes tend to become unstable, in several different ways, if their specific ...

SCALING ASYMPTOTICS FOR QUANTIZED HAMILTONIAN FLOWS [PDF]

open access: yesInternational Journal of Mathematics, 2012
In recent years, the near diagonal asymptotics of the equivariant components of the Szegö kernel of a positive line bundle on a compact symplectic manifold have been studied extensively by many authors. As a natural generalization of this theme, here we consider the local scaling asymptotics of the Toeplitz quantization of a Hamiltonian ...

Goodness-of-Fit Test of Shapiro-Wilk Type with Nuisance Regression and Scale

open access: yesAustrian Journal of Statistics, 2016
Shapiro and Wilk (1965) proposed a highly intuitive goodness-of-fit test of normality with nuisance location and scale parameters. The test has received a considerable attention in the literature; its asymptotic null distribution is covered by the ...

Photonic superdiffusive motion in resonance line radiation trapping - partial frequency redistribution effects [PDF]

open access: yes, 2007
The relation between the jump length probability distribution function and the spectral line profile in resonance atomic radiation trapping is considered for Partial Frequency Redistribution (PFR) between absorbed and reemitted radiation. The single line

Qualitative aspects of Volterra integro-dynamic system on time scales

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2013
This paper deals with the resolvent, asymptotic stability and boundedness of the solution of time-varying Volterra integro-dynamic system on time scales in which the coefficient matrix is not necessarily stable.

Asymptotic Performance Analysis of Large-Scale Active IRS-Aided Wireless Network

open access: yesIEEE Open Journal of the Communications Society, 2023
In this paper, the dominant factor affecting the performance of active intelligent reflecting surface (IRS) aided wireless communication networks in Rayleigh fading channel, namely the average signal-to-noise ratio (SNR) $\gamma _{0}$ at IRS, is ...

Asymptotic Preserving numerical schemes for multiscale parabolic problems [PDF]

open access: yes, 2015
We consider a class of multiscale parabolic problems with diffusion coefficients oscillating in space at a possibly small scale $\varepsilon$. Numerical homogenization methods are popular for such problems, because they capture efficiently the asymptotic
