Bistability and low-frequency fluctuations in semiconductor lasers with optical feedback: a theoretical analysis
Near-threshold operation of a semiconductor laser exposed to moderate optical feedback may lead to low-frequency fluctuations. In the same region, a kink is observed in the light-current… Expand
Excitation wave propagation as a possible mechanism for signal transmission in pancreatic islets of Langerhans.
In response to glucose application, beta-cells forming pancreatic islets of Langerhans start bursting oscillations of the membrane potential and intracellular calcium concentration, inducing insulin… Expand

Dynamics of breathers in discrete nonlinear Schro¨dinger models
Abstract We review some recent results concerning the existence and stability of spatially localized and temporally quasiperiodic (non-stationary) excitations in discrete nonlinear Schrodinger (DNLS)… Expand

A reaction-diffusion type model is constructed, describing the spatio-temporal dynamics of the basic intracellular variables assumed to be involved in the initiation of the insulin secretion process… Expand
Nuclear stopping and rapidity loss in Au+Au collisions at sNN=62.4 GeV
Abstract Transverse momentum spectra of protons and anti-protons measured in the rapidity range 0 y 3.1 from 0–10% central Au + Au collisions at s N N = 62.4 GeV are presented. The rapidity… Expand
Complex Dynamics in Spatially Extended Systems
Self-organization, or the spontaneous emergence of patterns and structures under far-from-equilibrium conditions, turbulence, and related nonlinear dynamic phenomena in spatially extended systems… Expand
