Modeling stochastic gene expression: From Markov to non-Markov models

open access: yesMathematical Biosciences and Engineering, 2020
Gene expression is an inherently noisy process due to low copy numbers of mRNA or protein. The involved reaction events may happen in a Markov fashion but also in a non-Markov manner, depending on waiting-time distributions for the occurrence of reaction

Analysis of classical retrial queue with differentiated vacation and state dependent arrival rate.

open access: yesRatio Mathematica, 2021
In present paper we have introduced the concept of differentiated vacations in a retrial queueing model with state dependent arrival rates of customers. The arrival rate of customers is different in various states of the server.

Fast reactions with non-interacting species in stochastic reaction networks

open access: yesMathematical Biosciences and Engineering, 2022
We consider stochastic reaction networks modeled by continuous-time Markov chains. Such reaction networks often contain many reactions, potentially occurring at different time scales, and have unknown parameters (kinetic rates, total amounts). This makes

Markov genealogy processes

open access: yesTheoretical Population Biology, 2022
We construct a family of genealogy-valued Markov processes that are induced by a continuous-time Markov population process. We derive exact expressions for the likelihood of a given genealogy conditional on the history of the underlying population process.
