Stochastic models of the growth dynamics of some dendritic cells

open access: yesbioRxiv, 2018
Different models of tumor growth are considered. Some mathematical methods are developed to analyze the dynamics of mutations enabling cells in cancer patients to metas-tize. The mathematical models consist of some stochastic dynamical systems describing

An Optimal Control Study for a Two‐Strain SEIR Epidemic Model With Saturated Incidence Rates and Treatment

open access: yesDiscrete Dynamics in Nature and Society, Volume 2025, Issue 1, 2025.
This work will study an optimal control problem describing the two‐strain SEIR epidemic model. The model studied is in the form of six nonlinear differential equations illustrating the dynamics of the susceptible and the exposed, the infected, and the recovered individuals.

Amplitude distribution of stochastic oscillations in biochemical networks due to intrinsic noise

open access: yes, 2009
Intrinsic noise is a common phenomenon in biochemical reaction networks and may affect the occurence and amplitude of sustained oscillations in the states of the network.

The Impact of Intervention Strategies on the Dissemination of Monkeypox Utilizing Fractional Differential Equations

open access: yesJournal of Mathematics, Volume 2025, Issue 1, 2025.
In this study, we develop a compartmental mathematical model to offer a thorough understanding of the dynamics of monkeypox viral transmission. We examine the sensitivity of the epidemic model to the fundamental reproduction number (R0). We also utilize an expanded Euler technique to scrutinize the dynamics of monkeypox transmission between humans and ...

Bifurcations for a deterministic SIR epidemic model in discrete time

open access: yes, 2014
In this paper, we are concerned with the theoretical analysis of the bifurcations for a deterministic SIR epidemic model in discrete time. By deriving equations describing flows on the center manifolds, we discuss the transcritical bifurcation at the ...

Approximation operators based on preconcepts

open access: yesOpen Mathematics, 2020
Using the notion of preconcept, we generalize Pawlak’s approximation operators from a one-dimensional space to a two-dimensional space in a formal context.

Distribution of Purines and Pyrimidines over miRNAs of Human, Gorilla and Chimpanzee

open access: yes, 2017
Meaningful words in English need vowels to break up the sounds that consonants make. The Nature has encoded her messages in RNA molecules using only four alphabets A, U, C and G in which the nine member double-ring bases (adenine (A) and Guanine (G)) are

Variational multiscale stabilized FEM for cardiovascular flows in complex arterial vessels under magnetic forces

open access: yesComputational and Mathematical Biophysics
In this study, we present a variational multiscale stabilized finite element method for steady-state incompressible fluid flow under magnetic forces. In particular, an algebraic approach of approximating the subscales has been considered, and then, the ...

Model and Simulation of COVID-19 Transmission with Vaccination and Quarantine Interventions in Jember

open access: yesInPrime, 2023
In this study, we model the transmission of COVID-19 by considering vaccination and quarantine interventions. The focus of our study is to measure the effect of these two interventions on controlling the spread of COVID-19.
