Creating bound states in excitable media by means of nonlocal coupling.

Physical review. E, Statistical, nonlinear, and soft matter physics

Bordyugov G, Engel H.
PMID: 16907175
Phys Rev E Stat Nonlin Soft Matter Phys. 2006 Jul;74(1):016205. doi: 10.1103/PhysRevE.74.016205. Epub 2006 Jul 17.

We consider pulses of excitation in reaction-diffusion systems subjected to nonlocal coupling. This coupling represents long-range connections between the elements of the medium; the connection strength decays exponentially with the distance. Without coupling, pulses interact only repulsively and bound...

Reindeer herding is a vitally important agricultural sector in the Russian Far North. It is believed that Northern ecosystems readily accumulate persistent pollutants because of trophic chains and climate features peculiar to the region. Reindeers graze on vast areas,...

Computation of the response functions of spiral waves in active media.

Physical review. E, Statistical, nonlinear, and soft matter physics

Biktasheva IV, Barkley D, Biktashev VN, Bordyugov GV, Foulkes AJ.
PMID: 19518588
Phys Rev E Stat Nonlin Soft Matter Phys. 2009 May;79(5):056702. doi: 10.1103/PhysRevE.79.056702. Epub 2009 May 11.

Rotating spiral waves are a form of self-organization observed in spatially extended systems of physical, chemical, and biological natures. A small perturbation causes gradual change in spatial location of spiral's rotation center and frequency, i.e., drift. The response functions...

In addition to being endogenous, a circadian system must be able to communicate with the outside world and align its rhythmicity to the environment. As a result of such alignment, external Zeitgebers can entrain the circadian system. Entrainment expresses...

Co-existing feedback loops generate tissue-specific circadian rhythms.

Gene regulatory feedback loops generate autonomous circadian rhythms in mammalian tissues. The well-studied core clock network contains many negative and positive regulations. Multiple feedback loops have been discussed as primary rhythm generators but the design principles of the core...

Wave trains in an excitable FitzHugh-Nagumo model: bistable dispersion relation and formation of isolas.

Physical review. E, Statistical, nonlinear, and soft matter physics

Röder G, Bordyugov G, Engel H, Falcke M.
PMID: 17500764
Phys Rev E Stat Nonlin Soft Matter Phys. 2007 Mar;75(3):036202. doi: 10.1103/PhysRevE.75.036202. Epub 2007 Mar 02.

We investigate the dispersion relations of nonlinear periodic wave trains in excitable systems which describe the dependence of the propagation velocity on the wavelength. Pulse interaction by oscillating pulse tails within a wave train leads to bistable wavelength bands,...
