(a) The probability density function (pdf) of residence times of a cargo on a microtubule, ψ(τ), for an ensemble of N = 6 motors (solid curve) calculated using Eq (4) with a particular set of p_i and λ_i. We chose p_i such that ∑_i p_i = 1. The dashed curve is the power-law fit ψ(τ) ∼ Aτ^−μ−1 with μ = 1.4 and A = 0.012. This power-law pdf corresponds to the rate ${\mathbb{T}}_d\left(\tau \right)\sim \mu /\tau$, which is consistent with the long time behaviour of Eq (6). Notice that 12 parameters (p_i and λ_i) are parametrized by only two parameters A and α. (b) The time averaged variances TAVARs (the time averaged mean squared displacements corrected for the drift) calculated along single trajectories generated with the residence times of the cargo on the microtubule shown in (a) grow as Δ^3−μ = Δ^1.6 (red dashed-double-dotted curve).
