Analysis of Discrete-Time Queues with Branching Arrivals

open access: yesMathematics, 2023
We consider a discrete-time single server queueing system, where arrivals stem from a multi-type Galton–Watson branching process with migration. This branching-type arrival process exhibits intricate correlation, and the performance of the corresponding ...

Period-Life of a Branching Process with Migration and Continuous Time

open access: yesMathematics, 2021
The homogeneous branching process with migration and continuous time is considered. We investigated the distribution of the period-life τ, i.e., the length of the time interval between the moment when the process is initiated by a positive number of ...

A Predator–Prey Two-Sex Branching Process

open access: yesMathematics, 2020
In this paper, we present the first stochastic process to describe the interaction of predator and prey populations with sexual reproduction. Specifically, we introduce a two-type two-sex controlled branching model.

Limiting Behaviors of Stochastic Spread Models Using Branching Processes

open access: yesAxioms, 2023
In this paper, we introduce a spread model using multi-type branching processes to investigate the evolution of the population during a pandemic in which individuals are classified into different types.

Neuronal Avalanches to Study the Coordination of Large-Scale Brain Activity: Application to Rett Syndrome

open access: yesFrontiers in Psychology, 2020
Many complex systems, such as the brain, display large-scale coordinated interactions that create ordered patterns. Classically, such patterns have been studied using the framework of criticality, i.e., at a transition point between two qualitatively ...

CALCULATION OF WEIGHT COEFFICIENTS IN CONTINUOUS PARTICLE FILTER

open access: yesНаучный вестник МГТУ ГА, 2018
This article shows the relationship between filters based on modeling of the random process paths with terminating and branching and a continuous particle filter that are related to sequential Monte Carlo methods.

Self-Similarity in Population Dynamics: Surname Distributions and Genealogical Trees

open access: yesEntropy, 2015
The frequency distribution of surnames turns out to be a relevant issue not only in historical demography but also in population biology, and especially in genetics, since surnames tend to behave like neutral genes and propagate like Y chromosomes.

Geometric branching reproduction Markov processes

open access: yesModern Stochastics: Theory and Applications, 2020
We present a model of a continuous-time Markov branching process with the infinitesimal generating function defined by the geometric probability distribution.

Coupling a branching process to an infinite dimensional epidemic process [PDF]

open access: yes, 2007
Branching process approximation to the initial stages of an epidemic process has been used since the 1950's as a technique for providing stochastic counterparts to deterministic epidemic threshold theorems.

Not all fun and games: Potential incidence of SARS-CoV-2 infections during the Tokyo 2020 Olympic Games

open access: yesMathematical Biosciences and Engineering, 2021
The Tokyo 2020 Olympic and Paralympic Games represent the most diverse international mass gathering event held since the start of the coronavirus disease 2019 (COVID-19) pandemic. Postponed to summer 2021, the rescheduled Games were set to be held amidst
