Analysis of an MMAP/PH1, PH2/N/∞ queueing system operating in a random environment
International Journal of Applied Mathematics and Computer Science, 2014 A multi-server queueing system with two types of customers and an infinite buffer operating in a random environment as a model of a contact center is investigated. The arrival flow of customers is described by a marked Markovian arrival process.

Finite-range viscoelastic subdiffusion in disordered systems with inclusion of inertial effects
New Journal of Physics, 2020 This work justifies further paradigmatic importance of the model of viscoelastic subdiffusion in random environments for the observed subdiffusion in cellular biological systems.

Austrian Journal of Statistics, 2023 For a continuous-time lattice random walk $X^\Lambda=\set{X^\Lambda_t,t\ge 0}$ in a random environment $\Lambda$, we study the asymptotic behavior, as $t\rightarrow \infty$, of the normalized additive functional $c_t\int_0^{t} f(X^\Lambda_s)ds$, $t\ge 0$

Random walk on nonnegative integers in beta distributed random environment [PDF]
, 2022 We consider random walks on the nonnegative integers in a space-time dependent random environment. We assume that transition probabilities are given by independent $\mathrm{Beta}(\mu,\mu)$ distributed random variables, with a specific behaviour at the ...

Lingering Random Walks in Random Environment on a Strip [PDF]
Communications in Mathematical Physics, 2007 We consider a recurrent random walk (RW) in random environment (RE) on a strip. We prove that if the RE is i. i. d. and its distribution is not supported by an algebraic subsurface in the space of parameters defining the RE then the RW exhibits the (log t)2 asymptotic behaviour. The exceptional algebraic subsurface is described by an explicit system of

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Although significant progress has been made in childhood leukemia survival, healthcare providers, and caregivers often face challenges in explaining this disease to patients. Disease‐targeted storybooks have been proposed as a tool to facilitate the understanding of diagnoses and treatment.

Edge reinforced random walk on Galton-Watson trees [PDF]
, 2023 reservedConsider a random walk in a graph and introduce a reinforcement on the edges so that the ones already traversed are more likely to be traversed in the future. We call such a process edge reinforced random walk (ERRW).

On subcritical multi-type branching process in random environment [PDF]
Discrete Mathematics & Theoretical Computer Science, 2008 We investigate a multi-type Galton-Watson process in a random environment generated by a sequence of independent identically distributed random variables.

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

Cut points and diffusive random walks in random environment [PDF]
, 2003 We study in this work a special class of multidimensional random walks in random environment for which we are able to prove in a non-perturbative fashion both a law of large numbers and a functional central limit theorem. As an application we provide new
