Mean field conditions for coalescing random walks [PDF]
, 2013 The main results in this paper are about the full coalescence time $\mathsf{C}$ of a system of coalescing random walks over a finite graph $G$. Letting $\mathsf{m}(G)$ denote the mean meeting time of two such walkers, we give sufficient conditions under ...

IEEE Access, 2019 In the absence of sufficient degradation data of long-lifetime and highly reliable products, a step-stress accelerated degradation model based on nonlinear diffusion process is proposed to estimate the remaining useful life (RUL), with the advantage of ...

Hitting Time Asymptotics for Hard-Core Interactions on Grids [PDF]
, 2015 We consider the hard-core model with Metropolis transition probabilities on finite grid graphs and investigate the asymptotic behavior of the first hitting time between its two maximum-occupancy configurations in the low-temperature regime. In particular,

Tunneling behavior of Ising and Potts models in the low-temperature regime [PDF]
, 2018 We consider the ferromagnetic $q$-state Potts model with zero external field in a finite volume and assume that the stochastic evolution of this system is described by a Glauber-type dynamics parametrized by the inverse temperature $\beta$.

Automatic identification of optimal marker genes for phenotypic and taxonomic groups of microorganisms. [PDF]
PLoS ONE, 2018 Finding optimal markers for microorganisms important in the medical, agricultural, environmental or ecological fields is of great importance. Thousands of complete microbial genomes now available allow us, for the first time, to exhaustively identify ...

An Adaptive Prognostic Approach for Newly Developed System With Three-Source Variability
IEEE Access, 2019 Remaining useful life (RUL) estimation is the key of prognostics and health management (PHM) technology and is an effective way to ensure the safe and reliable operation of equipment.

A martingale analysis of first passage times of time-dependent Wiener diffusion models
, 2016 Research in psychology and neuroscience has successfully modeled decision making as a process of noisy evidence accumulation to a decision bound. While there are several variants and implementations of this idea, the majority of these models make use of ...
