Understanding Measles Contagion: A Fractional‐Order Model With Stability and Sensitivity Insights
Journal of Mathematics, Volume 2026, Issue 1, 2026.In this paper, we propose an epidemiological mathematical model described by a system of nonlinear differential equations of fractional order (FODEs). Specifically, we employ the Caputo fractional derivative (CFD). Our analysis verifies the existence of a solution.

Estimating Environmental Transmission Risk From Host Movement Data
Ecology and Evolution, Volume 15, Issue 12, December 2025.We present a comparative modeling framework that integrates host movement, pathogen persistence, and behavior to quantify environmentally mediated transmission. Using wild pig GPS data and SEIR simulations, we show that contact definitions significantly alter transmission dynamics, highlighting the importance of mechanistically defining indirect ...

Dynamics of disease spread. Effect of the characteristic times
Condensed Matter Physics, 2019 Dynamic properties of spreading infection through a heterogeneous population are studied numerically and analytically using a dynamic variant of Watts and Strogatz Small World Network-based stochastic Susceptible-Exposed-Infectious-Removed (SEIR ...

First principles modeling of nonlinear incidence rates in seasonal epidemics. [PDF]
PLoS Computational Biology, 2011 In this paper we used a general stochastic processes framework to derive from first principles the incidence rate function that characterizes epidemic models.

Risk Analysis, Volume 45, Issue 12, Page 4272-4288, December 2025.Abstract Hepatitis E virus (HEV) can lead to liver disease in humans. In the Netherlands, the consumption of pig meat is thought to be the main contributor to the total burden of disease caused by HEV. In this study, the number of cases and lost disability‐adjusted‐life‐years (DALYs) due to HEV in pig meat were estimated by simulating HEV through the ...

Naval Research Logistics (NRL), Volume 72, Issue 7, Page 975-993, October 2025.ABSTRACT The COVID‐19 pandemic has reverberated across global industries, including the international container shipping industry, where freight rates have become highly volatile. However, shipping lines appeared to thrive, particularly during the pandemic's initial 2 years.

A unifying class of compound Poisson integer‐valued ARMA and GARCH models
Scandinavian Journal of Statistics, Volume 52, Issue 3, Page 1176-1205, September 2025.Abstract INAR (integer‐valued autoregressive) and INGARCH (integer‐valued GARCH) models are among the most commonly employed approaches for count time series modeling, but have been studied in largely distinct strands of literature. In this paper, a new class of generalized integer‐valued ARMA (GINARMA) models is introduced which unifies a large number

Partial Differential Equations in Applied MathematicsThe stochastic SEIR model was employed to investigate the dynamics of influenza transmission. By incorporating transmission rates and prevalence ratios, this model provides the most comprehensive explanation of the virus’s unpredictable dissemination. To
