具有广义渠化规则的布尔网络的稳定性

The Stability of Boolean Networks with Generalized Canalizing Rules

Andrew Pomerance, Michelle Girvan, Ed Ott

摘要:

布尔网络是离散动态系统,其中每个节点的状态(0或1)在每个时间t更新到由那些节点在时间t-1的状态所确定的状态,这些节点有链接到它。当这些系统被用来模拟遗传控制,“渠道化”的情况下更新规则是特别感兴趣的。通道化规则是这样一种规则,对于该规则,当输入节点处于其通道化状态时,节点在时间$t$的状态由其输入中的单个输入在时间t-1的状态确定。以前的工作在布尔网络的有序/无序过渡考虑复杂的,非随机的网络拓扑结构。在目前的论文中,我们扩展了以前的工作,以考虑渠道化行为。

英文摘要:

Boolean networks are discrete dynamical systems in which the state (zero or one) of each node is updated at each time t to a state determined by the states at time t-1 of those nodes that have links to it. When these systems are used to model genetic control, the case of 'canalizing' update rules is of particular interest. A canalizing rule is one for which a node state at time $t$ is determined by the state at time t-1 of a single one of its inputs when that inputting node is in its canalizing state. Previous work on the order/disorder transition in Boolean networks considered complex, non-random network topology. In the current paper we extend this previous work to account for canalizing behavior.
