适应性调控网络的微观动力学与临界性
Microdynamics and Criticality of Adaptive Regulatory Networks
摘要:
我们提出了一个模型的自适应调节网络组成的一个简单的生物动机重新布线程序耦合到一个基本的稳定性标准。由此产生的网络表现出特征的平稳重尾度分布,表现出复杂的结构微观动态并自组织到动态临界状态。我们分析表明,所观察到的临界结果的形成和打破的瞬态反馈回路在自适应过程中。
英文摘要:
We present a model of adaptive regulatory networks consisting of a simple biologically-motivated rewiring procedure coupled to an elementary stability criterion. The resulting networks exhibit a characteristic stationary heavy-tailed degree distribution, show complex structural microdynamics and self-organize to a dynamically critical state. We show analytically that the observed criticality results from the formation and breaking of transient feedback loops during the adaptive process.
