Epidemic Models in Populations of Varying SizeWe consider simple compartmental models for infectious diseases with exposed and infective periods of fixed length. In particular, we examine the effect of incorporating nonlinear population dynamics into such models on threshold phenomena and the stability of endemic equilibria.作者: Resection 時(shí)間: 2025-3-22 18:33

In an age-structured epidemic model with two interacting viral strains that confer partial cross-immunity, purely imaginary eigenvalues exists for some parameter values indicating the possibility of a limit cycle appearing through a Hopf bifurcation.作者: rheumatology 時(shí)間: 2025-3-23 07:52

A Distributed-Delay Model for the Local Population Dynamics of a Parasitoid-Host Systemthe parasitoids persist, and the equilibrium level of hosts can be forced to arbitrarily low values by extremely efficient parasitoids. The model is intended to describe the dynamics of a single patch in a system where host dispersal greatly exceeds parasitoid dispersal, and may have implications for biological control under these circumstances.作者: 得體 時(shí)間: 2025-3-24 01:44

We circumvent these computational problems by building highly structured models of individual cells and then using a finite-representation technique to model the whole population. Application of this technique to predicting protein production from recombinant DNA is described.作者: 不適當(dāng) 時(shí)間: 2025-3-24 06:52 作者: Decongestant 時(shí)間: 2025-3-24 12:06 作者: installment 時(shí)間: 2025-3-24 17:12 作者: 過于平凡 時(shí)間: 2025-3-24 21:42 作者: 違抗 時(shí)間: 2025-3-25 00:21
