Accelerated spike resampling for accurate multiple testing controls.

abstract：:A variant of spiking neural P systems with positive or negative weights on synapses is introduced, where the rules of a neuron fire when the potential of that neuron equals a given value. The involved values-weights, firing thresholds, potential consumed by each rule-can be real (computable) numbers, rational numbers,...

We define the robustness of synchrony by the critical disorder at which the asynchronous state becomes linearly unstable.
