Abstract

We study the signal percolation through heart-like biological system. Starting from an initial distribution of waiting and inactive cells with probabilities p and $(1 - p)$ respectively, the signal propagation is observed in terms of active cells. As the signal enters the system from one end, the number of arrival of active sites at the other end is studied and analysis of the system behaviour is made by varying a few important parameters of the system like $p_{s w i t c h}$ (switching probability from inactive to waiting) and $p_{a c t}$ (switching probability from waiting to active). In this connection, the non-regular heart rhythms are discussed. Fraction of paths percolating through the system shows a transition from 0 to 1 near $p = p_{c}$ . Some other important quantities like tortuosity and cluster distribution are discussed. Several critical exponents have been obtained and compared the exponents of standard percolation.

洞察渗流的类心系统

我们研究的是信号在类心脏生物系统中的渗透。从初始分布的等待细胞和不活跃细胞（概率分别为 p 和 (1-p)）开始，观察活跃细胞的信号传播。当信号从一端进入系统时，研究了到达另一端的活跃点的数量，并通过改变系统的几个重要参数，如 pswitch（从非活跃到等待的切换概率）和 pact（从等待到活跃的切换概率），对系统行为进行了分析。在这方面，还讨论了非规则心律。在 p=pc 附近，系统中渗透路径的比例显示出从 0 到 1 的过渡。还讨论了其他一些重要量，如迂回度和集群分布。得到了几个临界指数，并与标准渗滤的指数进行了比较。
