摘要:

我们提出了一个严格的数学框架,分析动态的一类广泛的布尔网络模型。我们使用这个框架提供了第一个正式的证明,在布尔网络分析的许多标准的关键转变的结果,并提供类似的刻画新的类的随机布尔网络。我们精确地将布尔网络的短期动态行为与传递函数的平均影响联系起来。我们发现,传统上在更常见的平均场分析布尔网络的一些假设一般不成立。例如,我们提供了一些证据表明,传递函数的不平衡或预期的内部不均匀性是一个至关重要的特征,它往往比以前观察到的更强烈地驱动静态行为。

英文摘要:

We present a rigorous mathematical framework for analyzing dynamics of a broad class of Boolean network models. We use this framework to provide the first formal proof of many of the standard critical transition results in Boolean network analysis, and offer analogous characterizations for novel classes of random Boolean networks. We precisely connect the short-run dynamic behavior of a Boolean network to the average influence of the transfer functions. We show that some of the assumptions traditionally made in the more common mean-field analysis of Boolean networks do not hold in general. For example, we offer some evidence that imbalance, or expected internal inhomogeneity, of transfer functions is a crucial feature that tends to drive quiescent behavior far more strongly than previously observed.
