MSD is the mean of the squared distance at each step over a given time period. Recent studies have not explored the differences as well as the potential implications of using the NSD or MSD. MSD provides smoother trajectories compared to NSD, which is highly …
WebMar 13, 2024 · To proceed, we calculate the mean square displacement of the particle from its initial position, R2(t) = (x(t) − x(0))2 = ∫t 0∫t 0 v(τ1)v(τ2) dτ2dτ1 = 2∫t 0(t − τ)C(τ)dτ. At … WebCalculating the mean square displacement A very brief tutorial. dx(t,tau) = x(t+tau) - x(t) Then, define < dx > = mean(dx(t,tau)) where the mean is taken over all initial times t, and all This is the mean displacement. Likewise, < dx^2 > …
WebThe size distribution of nanoparticles can be determined by single-particle tracking. This yields the mean-squared displacement (MSD) as a function of the lag time, and for normal diffusion the slope of this curve is directly related to the diffusion coefficient or via the Stokes–Einstein relation to the particle size. Here we demonstrate how the experimentally …
