In addition, we chose h as the bifurcation parameter and studied the existence and stability of flip bifurcation and Hopf bifurcation of this model by using the center manifold theorem and the bifurcation theory. Wan L, Xu R. In this work, the following work is achieved: Serious, as well as far-fetched accounts will give you a fresh insider’s perspective ldi the history of this time period. Funding China Postdoctoral Science Foundation.
If we take two eigenvalues of J E 1.
On completely irreducible operators. See our other membership options. Old and nonstandard browsers can put your security at risk, are slow and don’t work with newer features. Conditions will be derived for the existence of a flip bifurcation and a Hopf bifurcation by using bifurcation theory [ 1112 ] and the center manifold theorem [ 13 ]. Main results We firstly discuss the existence of the equilibria of model 2. Make the information on this image better by adding what you know.

Berryman and Millstein [ 3 ] investigated an SVEIS epidemic model for an infectious disease that spreads in the host population through horizontal transmission, and they have shown that the model exhibits two equilibria, namely, the disease-free equilibrium and the endemic equilibrium.
In addition, a precise description of secondary fractures in SRV regions is of critical importance for production analysis leii prediction. Footnotes Competing interests The authors declare that they have no conflict of interest.

Due to the impact of hydraulic fracturing, induced fractures in SRV regions are often irregular. Guckenheimer and Holmes [ lek ] examined an SIR epidemic model with a non-monotonic incidence rate, and they also analyzed the dynamical behavior of the model and derived the stability conditions for the disease-free and the endemic equilibrium.
How does Europe PMC derive its 1464 network? About this image Short Description: A free boundary problem for a ratio-dependent diffusion predator-prey system.
May and Odter [ 1 ] proposed a time-periodic reaction-diffusion epidemic model which incorporates a simple demographic structure and the latent period of an infectious disease. Received Feb 8; Accepted Jun 7. Both authors read 14164 approved the final manuscript. Robinson C, Holmes P. Jiang Z, Sun S. Guckenheimer J, Holmes P. Compared with previous numerical and analytic methods, the developed model can provide more accurate dynamic parameter estimates for production analysis in a computationally efficient manner.

It is found that the flow can be classified as six stages, including a bi-linear flow regime, a linear flow regime, a transition flow regime, an inter-porosity flow regime from the matrix to the fractures in the inner region, inter-porosity flow regime from matrix to fractures in the outer region, and a boundary dominant flow regime.
