Long-term Coexistence of Epidemics and Risk Awareness: Impacts of Adaptive Human Response and Fatigue
Mozzamil Mohammed, Abdallah Alsammani
Human behavior shapes epidemic dynamics, yet most models represent it by rescaling the transmission rate, which conflates behavior with biology and fails to capture the memory asso…
Adaptive Control and Mittag-Leffler Stability of Caputo Fractional Systems with State-Dependent Delays
Abdallah Alsammani, Gassan Farah
This paper establishes new sufficient conditions for Mittag-Leffler stability of Caputo fractional-order nonlinear systems with state-dependent delays. The central analytical tool…
Stochastic Dynamics of Hepatitis B Virus Infection: Extinction, Persistence, and Ergodicity
Abdallah Alsammani
We develop and analyze a three-compartment stochastic model of within-host hepatitis B virus infection with multiplicative Itô noise. We establish global well-posedness, strict pos…
Threshold Dynamics and Integrated Control of Cholera Transmission with Sanitation and Vaccination
Abdallah Alsammani, Gassan A. M. O. Farah, Mohammed A. Y. Mohammed +1
Cholera transmission is sustained by interacting human and environmental pathways, making integrated control essential in settings with inadequate water, sanitation, and hygiene in…
