WebThe first passage time (FPT) is a parameter often used to describe the scale at which patterns occur in a trajectory. For a given scale r, it is defined as the time required by the animals to pass through a circle of radius r. WebThe mean-first-passage time is now the reciprocal of the flux between position 0 and s, because in steady-state 0 represents the total incoming particle flux to the system. The mean-first-passage time for a random walk with arbitrary rates and shortcuts can then be calculated according to: 𝑇 n _ q q= s 0 −1 −1 ∑𝑝 á á=0
WebSep 17, 2013 · The mean first-passage time (MFPT), as an importantly statistical physical quantity, has been only studied by analytic formula either in one dimensional system [ 37] or in a few simple two-dimension and three-dimension systems.
