https://doi.org/10.1007/b102725nswer is simply that, depending on parameters of the system, spiral waves in excitable media can execute either periodic rotations or a fascinating variety of other deterministic dynamics. This chapter is a review of the current understanding of complexity of spiral dynamics from a bifurcation-theor哀悼 发表于 2025-3-23 20:19:38
https://doi.org/10.1007/b102725ever, this naive statement is actually false because, when several species have different diffusion rates, the responses of the antagonistic processes to a local perturbation do not spread at the same rate. As a result, the subtle balance between these processes can break in a nonhomogeneous way. InLAVA 发表于 2025-3-23 23:01:05
Epidemiology of Reproductive Health,ature whether initiation of chemical waves in excitable and oscillatory systems occurs by thermal fluctuations or by heterogeneous means, such as dust particles in the solution of the reactive system. We address this issue and show by numerical solutions of deterministic reaction-diffusion equationsBasilar-Artery 发表于 2025-3-24 03:15:40

Promoting Community Resilience in Disastersacid excitable medium. It is largely organized around putatively corresponding computations in two or three spatial dimensions (‘2D’ or ‘3D’ henceforth) with the two-variable Oregonator model. This reduced model is far superior to ‘generic’ excitable systems or ‘lambda-omega’ equations for interpretsurmount 发表于 2025-3-24 20:52:08
