susceptible – infected model1.Lianas are structural parasites of trees that reduce the growth, survival and reproduction of their hosts. Given that co﹐ccurring tree species differ strongly in the proportion of individuals that are infested by lianas (liana prevalence), lianas could differentially ...
This chapter investigates just one of these models, a modified Volterra host-parasite model, to illustrate the application of the methodology outlined in Chapter 9 which focuses on the underlying cumulant structure of the stochastic model.Page %P Close Plain text Look Inside Chapter Metrics ...
In this paper, a model is analyzed which, while assuming all individuals to be alike, can still lead to a very heterogeneous distribution of parasites among the host population. The model can be viewed as a very simple mean field interacting particle system, with the particles corresponding to...
In this paper, we investigate the dynamical outcomes of a host-parasite model incorporating both horizontal and vertical transmissions in a spatial heterogeneous environment analytically and numerically. Our study provides valuable insights in two aspects: Mathematically, we propose three threshold parameters...
The life cycle of the parasite is described and a model for the dynamics of its interaction with the fish is described and analyzed. The model consists of a coupled system of ordinary differential equations and one integro-differential equation....
In the local view, GLIL becomes P-LSTMs that model the person-level motionsby the neighboring interaction under an interaction gate. 邻居间的相互作用(通过一个来interaction gate呈现) 对Person-Level的动作表示: 三种输入:当前时刻的结点状态d, 上一时刻结点的隐藏层状态h,邻居结点的上一时刻状态的组合...
Here we explore a spatially structured host-parasite model with mixture of the horizontal and vertical transmissions under heterogeneous environment induced from fragmented landscape/resource quality. By pair-approximation model, we find that more fragmented landscape (high amount of habitat loss and/or ...

Here I have presented a model in which a host population, regulated by infection due to some focal pathogen, is structured into various risk classes due to exposure to some factor that enhances the disease characteristics of a focal infection.
