A vaccination model for COVID-19 in Gauteng, South Africa
Infectious Disease Modelling, 2022 The COVID-19 pandemic provides an opportunity to explore the impact of government mandates on movement restrictions and non-pharmaceutical interventions on a novel infection, and we investigate these strategies in early-stage outbreak dynamics.

Memory Effect on COVID‐19 Vaccination Dynamics: Fractional‐Order Modeling Approach
Journal of Applied Mathematics, Volume 2026, Issue 1, 2026.Accurate estimates of vaccine effectiveness are essential for designing effective COVID‐19 vaccination strategies. Memory effects play a critical role in both the development and waning of vaccine‐induced immunity. In this study, we develop a fractional‐order COVID‐19 transmission model using Caputo fractional derivatives to capture the memory ...

Bayesian Inference for SIR Epidemic Model with dependent parameters
Moroccan Journal of Pure and Applied Analysis, 2022 This paper is concerned with the Bayesian inference for the dependent parameters of stochastic SIR epidemic model in a closed population. The estimation framework involves the introduction of m − 1 latent data between every pair of observations. Kibble’s

Temperature‐Driven Dynamics of Tomato Yellow Leaf Curl Virus: A Mathematical Modeling Approach
Journal of Applied Mathematics, Volume 2026, Issue 1, 2026.Purpose Tomato yellow leaf curl virus (TYLCV), transmitted by whiteflies, is a highly destructive pathogen that threatens tomato production worldwide. Temperature plays a crucial role in determining how tomato plants respond to TYLCV infection, primarily because it influences the activity and population dynamics of insect vectors.

How to Obtain Long Term Projections for Smoking Behaviour: A Case Study in the Dutch Population
Computational and Mathematical Methods in Medicine, Volume 10, Issue 2, Page 155-164, 2009., 2009 A state‐transition model is presented to project the prevalence rates of never, current and former smokers within the Dutch population. Changes are determined by the transition rates among these three classes: start rates, quit rates and relapse rates. Both the initial prevalence rates and transition rates are calculated from cross‐sectional data using

Are the upper bounds for new SARS-CoV-2 infections in Germany useful?
Computational and Mathematical Biophysics, 2021 At the end of 2019, an outbreak of a new coronavirus, called SARS–CoV–2, was reported in China and later in other parts of the world. First infection reported in Germany by the end of January 2020 and on March 16th, 2020 the federal government announced ...

Determination in Galicia of the required beds at Intensive Care Units
Alexandria Engineering Journal, 2021 By using a recent mathematical compartmental model that includes the super-spreader class and developed by Ndaïrou, Area, Nieto, and Torres, a procedure to estimate in advance the number of required beds at intensive care units is presented.

Journal of Applied Mathematics, Volume 2026, Issue 1, 2026.Trachoma remains a leading cause of preventable blindness in many low‐resource settings, driven by persistent transmission within closely interacting age groups. In this study, we develop and analyze a nonlinear age‐structured compartmental model that captures the transmission dynamics of trachoma between children and adults.
