Dynamical membrane curvature instability controlled by intermonolayer friction
Dynamical membrane curvature intermonolayer friction phospholipid membrane
2011/8/16
Abstract: We study a dynamical curvature instability caused by a local chemical modification of a phospholipid membrane. In our experiments, a basic solution is microinjected close to a giant unilamel...
Dynamical quorum-sensing and synchronization of nonlinear oscillators coupled through an external medium
Dynamical quorum-sensing nonlinear oscillators coupled
2011/1/5
Many biological and physical systems exhibit population-density dependent transitions to synchronized oscillations in a process often termed "dynamical quorum sensing". Synchronization frequently aris...
The Moran model as a dynamical process on networks and its implications for neutral speciation
dynamical process networks implications
2011/1/5
In genetics the Moran model describes the neutral evolution of a bi-allelic gene in a population of haploid individuals subjected to mutations. We show in this paper that this model can be mapped into...
Growth of a population of bacteria in a dynamical hostile environment
Growth population bacteria dynamical hostile environment
2010/11/15
We study the growth of a population of bacteria in a dynamical hostile environment corresponding to the immune system of the colonised organism. The immune cells evolve as subcritical open clusters of...
Dynamical Entropy Production in Spiking Neuron Networks in the Balanced State
Dynamical Entropy Production Spiking Neuron Networks Balanced State
2010/4/6
We demonstrate deterministic extensive spatio-temporal chaos in the dynamics of spiking neuron networks in the balanced state. The analysis is based on numerically exact calculations of the full spect...
A comparative study of different integrate-and-fire neurons: spontaneous activity, dynamical response, and stimulus-induced correlation
integrate-and-fire neurons spontaneous activity dynamical response
2010/4/7
Stochastic integrate-and-fire (IF) neuron models have found widespread applications in computational neuroscience. Here we present results on the white-noise-driven perfect, leaky, and quadratic IF mo...
