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

A Weak Law of Large Numbers for Dependent Random Variables
Theory of Probability & Its Applications, 2023 \bad Each sequence $f_1,f_2,\dots$ of random variables satisfying $\lim_{M\to \infty}(M\sup_{k\in \mathbf N}\mathbf{P}(|f_k|>M))=0$ contains a subsequence $f_{k_1},f_{k_2},\dots$ which, along with all its subsequences, satisfies the weak law of large numbers $\lim_{N\to\infty}\bigl((1/N) \sum^N_{n=1} f_{k_n}- D_N\bigr)=0$ in probability. Here, $D_N$

Applied Sciences, 2022 The dynamics of a stochastic system that exhibits large fluctuations to a given state are almost deterministic due to weak random perturbations. Such large fluctuations occur with overwhelming probability in the vicinity of the so-called optimal path ...

Global observables for RW: Law of large numbers [PDF]
, 2021 We consider the sums TN = Nn=1N F(Sn) where Sn is a random walk on Zd and F : Zd → R is a global observable, that is, a bounded function which admits an average value when averaged over large cubes.

Implicit Subgrid-Scale Modeling of a Mach 2.5 Spatially Developing Turbulent Boundary Layer
Entropy, 2022 We employ numerically implicit subgrid-scale modeling provided by the well-known streamlined upwind/Petrov–Galerkin stabilization for the finite element discretization of advection–diffusion problems in a Large Eddy Simulation (LES) approach. Whereas its

Equivalence between Step Selection Functions and Biased Correlated Random Walks for Statistical Inference on Animal Movement. [PDF]
PLoS ONE, 2015 Animal movement has a fundamental impact on population and community structure and dynamics. Biased correlated random walks (BCRW) and step selection functions (SSF) are commonly used to study movements.

Mathematics, 2019 The aim of this work is to study generalizations of the notion of the mean. Kolmogorov proposed a generalization based on an improper integral with a decay rate for the tail probabilities.

Public Policy Through the Lens of Necessity
Voices in Bioethics, 2021 Photo by Nick Fewings on Unsplash INTRODUCTION Necessity can drive people’s behavior to extremes, and at times, can provide an excuse for otherwise criminal, illegal actions that, under normal circumstances, would be morally wrong.
