Before revision: We introduce a persistent random walk model with finite velocity and self-reinforcing directionality, which explains how exponentially distributed runs URLanize into superdiffusive L\'evy walks observed in active intracellular transport by Chen et. al. [ Nat. mat. , 2015].
After revision: We introduce a persistent random walk model with finite velocity and self-reinforcing directionality, which explains how exponentially distributed runs URLanize into truncated L\'evy walks observed in active intracellular transport by Chen et. al. [ Nat. mat. , 2015].
