Mechanisms of vortices termination in the cardiac muscle
D. Hornung, V. N. Biktashev, N. F. Otani +6
We propose a solution to a long standing problem: how to terminate multiple vortices in the heart, when the locations of their cores and their critical time windows are unknown. We…
A simple mathematical model of gradual Darwinian evolution: Emergence of a Gaussian trait distribution in adaptation along a fitness gradient
Vadim N. Biktashev
We consider a simple mathematical model of gradual Darwinian evolution in continuous time and continuous trait space, due to intraspecific competition for common resource in an ase…
Wave-train induced unpinning of weakly anchored vortices in excitable media
Alain Pumir, Sitabhra Sinha, S. Sridhar +6
A free vortex in excitable media can be displaced and removed by a wave-train. However, simple physical arguments suggest that vortices anchored to large inexcitable obstacles cann…
Genetically engineered cardiac pacemaker: stem cells transfected with HCN2 gene and myocytes - a model
Sandra Kanani, Alain Pumir, Valentine Krinsky
Artificial biological pacemakers were developed and tested in canine ventricles. Next steps will require obtaining oscillations sensitive to external regulations, and robust with r…
