Managing lethal cardiac arrhythmias is one of the biggest challenges in modern cardiology,
and hence it is very important to understand the factors underlying such arrhythmias. While …

Excitable media comprise a class of models for a wide range of physical, chemical, and
biological systems that exhibit spontaneous formation of spatial patterns. Patterns in …

We present an investigation of excitability effects on the dynamics of scroll waves partially
pinned to inert cylindrical obstacles in three-dimensional Belousov-Zhabotinsky excitable …

Rotors occurring in the heart underlie the mechanisms of cardiac arrhythmias. Answering
the question whether or not the location of rotors is related to local properties of cardiac …

Disruptions in the normal rhythmic functioning of the heart, termed as arrhythmia, often result
from qualitative changes in the excitation dynamics of the organ. The transitions between …

We present an investigation of the dynamics of scroll waves that are partially pinned to inert
cylindrical obstacles of varying lengths and diameters in three-dimensional Belousov …

Waves which switch a system from one state to another are often seen in usual life. A
classical example of such a, so-called, trigger wave is the propagation of a combustion front …

Many vital physiological processes are characterized by rhythmic activity, ranging from the
circadian clock regulating the daily sleep-wake cycle to temporal patterns of respiration that …

Biological networks are typically comprised of many parts whose interactions are governed
by nonlinear dynamics. This potentially imbues them with the ability to support multiple …
