where: V (t) is the voltage as a function of time in volts, a and b are arbitrary constants, τ is the exponential time constant in seconds, and t is the time in seconds. Figure 1 is an example of an ...

Thus, scale-free biomimetic networks where the decay exponent is larger than 2 but smaller than 2.5 could provide possible designs for associative memories and pattern recognition.

We study the contact process, together with a version of the percolation process with one continuously varying coordinate. It is proved here that the radius of the infected cluster has an ...
