Abstract. In this paper, a predator-prey-disease model with immune response in the infected prey is formulated. The basic reproduction number of the within-host model is defined and it is found that there are three equilibria: extinction equilibrium, infection-free equilibrium and infection-persistent equilibrium. The stabilities of these equilibria are completely determined by the reproduction...

objective(s): the present study was conducted to examine whether the standardized uptake value (suv) may be affected by the spatial position of a lesion in the radial direction on positron emission tomography (pet) images, obtained via two methods based on time-of-flight (tof) reconstruction and point spread function (psf). methods: a cylinder phantom with the sphere (30mm diameter), located in...

In this article, we examine the dynamics of a Chikungunya virus (CHIKV) infection model with two routes infection. The uses four categories, namely, uninfected cells, infected CHIKV virus, and antibodies. equilibrium points model, which consist free point for endemic point, are first analytically determined. Next, local stability is studied, based on basic reproduction number (R0) obtained by n...
