Mathematical Modeling of Pulse‐Seeded Metapopulation Dynamics for Andes Hantavirus Border Dispersal

open access: yesEngineering Reports, Volume 8, Issue 9, September 2026.
A pulse‐seeded metapopulation SEIR model for Andes hantavirus maritime dispersal shows that heterogeneous quarantine compliance determines secondary outbreak risk. The weakest‐compliance country governs global containment, while uniform compliance above ∼65%$$ \sim 65\% $$ reduces the global reproduction number below unity.

Optimal Control Analysis of Vertically Transmitted Infectious Diseases With Saturated Incidence and Nonlinear Treatment

open access: yesOptimal Control Applications and Methods, Volume 47, Issue 5, Page 1083-1100, September/October 2026.
Schematic representation of the proposed disease transmission model incorporating vertical transmission, saturated incidence, and nonlinear treatment. The study combines theoretical analysis, bifurcation and stability investigations, and optimal control techniques to evaluate prevention and treatment interventions.

Fractal–fractional model for analysis of tuberculosis infection using Ethiopia incidence data

open access: yesQuantitative Biology, Volume 14, Issue 3, September 2026.
Abstract In this study, a fractional‐order SEIuITR $SE{I}_{u}ITR$ model was proposed to examine the transmission of tuberculosis (TB) in the community. The proposed model was rigorously examined for well‐posedness. The basic reproduction number was also derived, and the disease‐free equilibrium was obtained.

The Concept of the Mixing Index

open access: yesWater Resources Research, Volume 62, Issue 9, September 2026.
Abstract Many current measures of mixing, such as the statistics of concentration, the scalar dissipation rate, or dilution index, are based on the dilution of a single component or pseudo‐component. Because of this, they miss the influence of numerous conditions that directly change true mixing, such as initial separation of chemically distinct water ...

Direct Lyapunov matrix function method for impulsive systems under structural perturbations

open access: yes, 2015
The authors develop the direct Lyapunov matrix function method for impulsive systems under structural perturbations. Sufficient conditions are obtained for asymptotic stability and instability of large scale impulsive systems under structural perturbations.
