Logarithmic speeds for one-dimensional perturbed random walk in random environment [PDF]

open access: yes, 2008
We study the random walk in random environment on Z+ = f0; 1; 2; : : :g, where the environment is subject to a vanishing (random) perturbation. The two particular cases that we consider are: (i) random walk in random environment perturbed from Sinai's ...

Complete convergence and complete moment convergence for weighted sums of extended negatively dependent random variables under sub-linear expectation

open access: yesJournal of Inequalities and Applications, 2017
In this paper, we study the complete convergence and complete moment convergence for weighted sums of extended negatively dependent (END) random variables under sub-linear expectations space with the condition of C V [ | X | p l ( | X | 1 / α ) ] < ∞ $C_{

Non-homogeneous random walks with non-integrable increments and heavy-tailed random walks on strips [PDF]

open access: yes, 2012
We study asymptotic properties of spatially non-homogeneous random walks with non-integrable increments, including transience, almost-sure bounds, and existence and non existence of moments for first-passage and last-exit times.

Abelian sharing, common informations, and linear rank inequalities

open access: yesJournal of Mathematical Cryptology, 2022
Dougherty et al. introduced the common information (CI) method as a method to produce non-Shannon inequalities satisfied by linear random variables, which are called linear rank inequalities.

Exponential inequalities and a strong law of large numbers for END random variables under sub-linear expectations

open access: yesAIMS Mathematics, 2023
<abstract><p>The focus of our work is to investigate exponential inequalities for extended negatively dependent (END) random variables in sub-linear expectations. Through these exponential inequalities, we were able to establish the strong law of large numbers with convergence rate $ O\left(n^{-1/2}\ln^{1/2}n\right) $.

Structural hybrid reliability index and its convergent solving method based on random–fuzzy–interval reliability model

open access: yesAdvances in Mechanical Engineering, 2016
Aiming to resolve the problems of a variety of uncertainty variables that coexist in the engineering structure reliability analysis, a new hybrid reliability index to evaluate structural hybrid reliability, based on the random–fuzzy–interval model, is ...

A convergence of fuzzy random variables [PDF]

open access: yes, 2003
summary:In this paper, a general convergence theorem of fuzzy random variables is considered. Using this result, we can easily prove the recent result of Joo et al, which gives generalization of a strong law of large numbers for sums of stationary and ...

Machine learning to predict end stage kidney disease in chronic kidney disease

open access: yesScientific Reports, 2022
The purpose of this study was to assess the feasibility of machine learning (ML) in predicting the risk of end-stage kidney disease (ESKD) from patients with chronic kidney disease (CKD). Data were obtained from a longitudinal CKD cohort.
