The application of the continuous‐time random walk model to the description of the non‐equilibrium stress response of a crosslinked network is discussed. Different versions of the continuous‐time random walk model lead to the prediction of a stress relaxation function having either a fractional‐...

To examine the relationship between wave eigenspectra and the correlations of potentials, three types of random-walk potentials are analysed: crystals, quasicrystals and disordered potentials, which are generated by adjusting the refractive index profile. Figure 1a represents a 1D binary Fibonacci ...

Nonintermittent stimuli occur, however, D times more often, and mood itself may “random-walk away” about equally far in both cases. Thus, for <T> = 1 year, mood is found outside the depression-manic limits, adopted as −2 and +2, with about the same probability, roughly 4% to ...
摘要: Using classical arguments we derive a formula for the moments of hitting times for an ergodic Markov chain. We apply this formula to the case of simple random walk on trees and show, with an elementary electric argument, that all the moments are natural numbers....
