The MSD of a nearly neutrally buoyant Brownian particle (a = 250 nm) in a stationary fluid medium using hybrid approach. The nondimensionalized characteristic memory times are ${\tau }_1\text{/}{\tau }_{\mathrm{\nu }}\hspace{1em}=\hspace{1em}0.12$ and ${\tau }_2\text{/}{\tau }_{\mathrm{\nu }}\hspace{1em}=\hspace{1em}0.088$ [33].
