Figure 5.

Distributions of the tMSD amplitude scatter $\zeta (t)$ for trajectories in MRC5 and RPE cells and for simulated trajectories of ensemble heterogeneous FBM model are broad. $PDF(\zeta )$ of $\zeta (t)={\text{tMSD}}_i(t)/\text{e-tMSD}(t)$ calculated at different time t (shown in the figure) for MCR5 and RPE trajectories (a) and trajectories of the ensemble heterogeneous FBM model (b). The dashed curve in (a) corresponds to a generalised Gamma distribution PDF$(\zeta )\sim {\zeta }^{\nu -1}exp(-a/\zeta -\zeta /b)$ with $a=0.018$, $b=0.01$ and $\nu =1.5$.
