    • In order to connect between the time scales of the two computational methods we use the identity D0 t/a2 = N ε2 /(6a2), where N is the number of random walk time steps. Thus, with ε/a = 0.01, we have t = 10-4Na2/(6D0). Taking a = 10 :μm and D0 = 2.5 :μ m2/msec we get the following correspondences: N = 1000 (t = 0.67 msec), N = 5000 (t = 3.33 msec), N = 10 ,000 (t = 6.67 msec), N = 20 ,000 (t = 13.33 msec), N = 40 ,000 (t = 26.67 msec), and N = 60 ,000 (t = 40.0 msec).
