The question of how network topology influences emergent synchronized oscillations in excitable media is addressed. Coupled van der Pol-FitzHugh-Nagumo elements arranged either on regular rings or on clusters of the square lattice are investigated. Clustered and declustered rings are constructed to have the same number of next-nearest-neighbors (four) and a(More)
Some critical considerations on the models of "extended irreversible thermodynamics" are given. By developing a methodology ("invariance of the generators") based both on the ideas of the "extended irreversible thermodynamics" and the "entropy principle" in its general formulation of "rational thermodynamics", a theory for a newtonian thermo-viscous fluid(More)
