Discrete stochastic modeling of calcium channel dynamics
Markus Baer, Martin Falcke, Herbert Levine +1
We propose a simple discrete stochastic model for calcium dynamics in living cells. Specifically, the calcium concentration distribution is assumed to give rise to a set of probabi…
Controlled Dynamics of Interfaces in a Vibrated Granular Layer
I. Aranson, D. Blair, W. Kwok +5
We present experimental study of a topological excitation, {\it interface}, in a vertically vibrated layer of granular material. We show that these interfaces, separating regions o…
Hexagons and Interfaces in a Vibrated Granular Layer
I. S. Aranson, L. S. Tsimring, V. M. Vinokur
The order parameter model based on parametric Ginzburg-Landau equation is used to describe high acceleration patterns in vibrated layer of granular material. At large amplitude of…
Penta-Hepta Defect Motion in Hexagonal Patterns
Lev S. Tsimring
Structure and dynamics of penta-hepta defects in hexagonal patterns is studied in the framework of coupled amplitude equations for underlying plane waves. Analytical solution for p…
