    Modelling transmission and control of Toxoplasma gondii in New Zealand farmland by Rachelle N. Binny, Graham J. Hickling, Alex James, Chris N. Niebuhr

    Published 2025-02-01
    “…Predator control of rodents and feral cats has potential to reduce or even eliminate transmission of T. gondii on farms; however, the efficacy of such management is uncertain. We apply a mathematical model of T. gondii transmission dynamics in feral cat and rodent populations in New Zealand farmland and simulate varying intensities of predator control to predict changes in T. gondii prevalence and environmental contamination levels over time. …”

    Blood coagulation dynamics: mathematicalmodeling and stability results by Adélia Sequeira, Rafael F. Santos, Tomáš Bodnár

    Published 2011-03-01
    “…Coagulation is initiated in response to endothelial surface vascular injury or certain biochemical stimuli, by the exposure of plasma to Tissue Factor (TF), that activates platelets and the coagulation cascade, inducing clot formation, growth and lysis.In recent years considerable advances have contributed to understand this highly complex process and some mathematical and numerical models have been developed. However, mathematical models that are both rigorous and comprehensive in terms of meaningful experimental data, are not available yet.In this paper a mathematical model of coagulation and fibrinolysis in flowing blood that integrates biochemical, physiologic and rheological factors, is revisited. …”
