    Abstract: The integrity of the cardiac cells and muscles is essential for quality of life. The sinoatrial node cells are the definitive cells of cardiac electrophysiology. They are the primary source of action potentials. Lamentably, the question of ion currents that generate the much needed cardiac action potentials is yet to be resolved. The nagging issue ...

    Abstract: In this paper, the objective was to find out the influence of introducing treatment at the latent period of disease (infectious) transmission as a result the global dynamics of the SEIR epidemic model with the introduction of treatment at the latent period is explored. The basic reproduction number is estimated. Whenever the basic reproduction numb... Show More
