Non-equilibrium ribbon model of scroll waves with twist

Autor: Echebarria, B., Hakim, V., Henry, H.

We formulate a reduced model to analyze the motion of the core of a twisted scroll wave. The model is first shown to provide a simple description of the onset and nonlinear evolution of the helical state appearing in the sproing bifurcation of scroll

Linear Stability of Scroll Waves

Autor: Henry, H., Hakim, V.

Publikováno v: Phys. Rev. Lett. 85 5328-5331 (2000)

A full linear stability of a straight scroll wave in an excitable medium is presented. The five eigenmode branches which correspond to deformation in the third dimension of the five main modes of two-dimensional (2D) spiral dynamics are found to play

Fast global oscillations in networks of integrate-and-fire neurons with low firing rates

Autor: Brunel, N., Hakim, V.

We study analytically the dynamics of a network of sparsely connected inhibitory integrate-and-fire neurons in a regime where individual neurons emit spikes irregularly and at a low rate. In the limit when the number of neurons N tends to infinity,th

Analysis of a dissipative model of self-organized criticality with random neighbors

Autor: Chabanol, M. -L., Hakim, V.

We analyze a random neighbor version of the OFC stick-slip model. We find that the mean avalanche size is finite as soon as dissipation exists in the bulk but that this size grows exponentially fast when dissipation tends to zero.

Background The evolution of animal segmentation is a major research focus within the field of evolutionary–developmental biology. Most studied segmented animals generate their segments in a repetitive, anterior-to-posterior fashion coordinated with
