SGER: Temporal and Spatial Scales in Models of Excitable Media

螺旋波是一种可激发介质的动力学行为，即从静止状态的微小变化消失而大变化产生振荡行为的介质。生物学中可兴奋介质的例子包括心脏、视网膜和各种器官中的钙波，如肠道。化学系统也表现出这些类型的变化，并提供了一个模型系统来研究螺旋波的开始和稳定性如何受到生物系统中存在的不同因素的影响。化学反应将用数学和计算两种方法进行分析。这一结果将有助于更好地理解生物系统中螺旋波的起伏和稳定性的动力学机制。

Spiral waves are a dynamical behavior of excitable media, that is, media in which small changes from the rest state die out and large changes generate oscillatory behavior. Examples of excitable media in biology include the heart, the retina, and calcium waves in various organs, such as the intestine. Chemical systems also exhibit these types of changes and provide a model system for studying how onset and stability of spiral waves are affected by different factors present in biological systems. The chemical reaction will be analyzed both mathematically and computationally. Results should lead to a better understanding of dynamical regime of spiral wave onset and stability in biological systems.
