Meanings of average msd in English

Moreover, time- averaged MSD exhibits aging and converges to a random variable following the modified Mittag-Leffler distribution.

In contrast, the time- averaged MSD shows normal diffusion, but an effective diffusion coefficient transiently shows aging behavior.

Also, the present method of a time- averaged MSD tensor could be used to analyze trajectory data obtained in SPT experiments.

Thus the crossover time gives some information on the relaxation time of fluctuating diffusivity which cannot be extracted from the ensemble- averaged MSD.
