Simulations of a heterogeneous FBM model with diffusion coefficients that depend on the duration of trajectories capture the main features of endosomal dynamics. (a) eMSD and e-tMSD as functions of time t. EMSD coincides with e-tMSD indicating ergodicity. (b) Conditional eMSDs as functions of time t for the subsets of hFBM trajectories with a duration longer than T seconds. The dashed and the dashed-dotted lines are power-law fits. (c) hFBM model mimics ageing behaviour in ensemble MSDs as a function of aging time (t-ta) and (d) in the decrease of e-tMSD as the measurement time, T, increases. The dashed line is the exponential function .
