The method of " estimating connectivity from spanning tree completions " (ECSTC) is specifically designed to address situations where only spanning tree(s) of a… (More)
There is considerable research relating the structure of Boolean networks to their state space dynamics. In this paper, we extend the standard model to include the effects of thermal noise, which has the potential to deflect the trajectory of a dynamical system within its state space, sending it from one stable attractor to another. We introduce a new "… (More)
