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.

Cancer recurrence times from a branching process model. [PDF]

open access: yesPLoS Computational Biology, 2019
As cancer advances, cells often spread from the primary tumor to other parts of the body and form metastases. This is the main cause of cancer related mortality.

A hybrid Ornstein–Uhlenbeck–Branching framework unifies microbial and pediatric tumor evolution [PDF]

open access: yesFrontiers in Oncology
IntroductionPediatric tumors can relapse despite low mutation burdens, suggesting hybrid evolutionary dynamics shaped by stochastic variability and stabilizing forces.

The Branching Process: A General Conceptual Framework for Addressing Current Ecological and Evolutionary Questions [PDF]

open access: yesLife
Classical branching-process theory, developed by Galton and Watson in the nineteenth century and later refined by Fisher and Haldane, provides the formal framework for quantifying the fate of new mutants, new viral and bacterial pathogens, new ...

Applications of the Delay Stochastic Simulation Algorithm (DSSA) in Mathematical Epidemiology

open access: yesMathematics, 2022
The calculation of the probability of a minor outbreak is crucial in analyzing a stochastic epidemic model. For stochastic epidemic models with fixed delays, the linear chain trick is applied to transform the delayed models into a family of ODE models ...

SimuBP: A Simulator of Population Dynamics and Mutations Based on Branching Processes

open access: yesAxioms, 2023
Originating from the Luria–Delbrück experiment in 1943, fluctuation analysis (FA) has been well developed to demonstrate random mutagenesis in microbial cell populations and infer mutation rates.

A Generalized Age-Dependent Branching Process and Its Limit Distribution [PDF]

open access: yesThe Egyptian Statistical Journal, 1970
An age-dependent continuous parameter branching stochastic process Xₙ(t) is considered, where Xₙ (t) is the number of particles in the population at time t and N is the initial size of the population. If the probabilities of splits depend on N.

Modelling the impact of travel restrictions on COVID-19 cases in Newfoundland and Labrador

open access: yesRoyal Society Open Science, 2021
In many jurisdictions, public health authorities have implemented travel restrictions to reduce coronavirus disease 2019 (COVID-19) spread. Policies that restrict travel within countries have been implemented, but the impact of these restrictions is not ...
