(a) and (c) Translational ($B\hspace{1em}=\hspace{1em}m{\rho }^{(f)1/2}\text{/}12{\pi }^{3/2}{\mu }^{3/2}$) and (b) and (d) rotational ($C\hspace{1em}=\hspace{1em}\mathit{I}{\rho }^{(f)3/2}\text{/}32{\pi }^{3/2}{\mu }^{5/2}$) VACFs of the Brownian particle (a = 250 nm) in a fluid medium through a circular vessel using hybrid approach. The nondimensionalized characteristic memory times are ${\tau }_1\text{/}{\tau }_{\nu }\hspace{1em}=\hspace{1em}0.12$ and ${\tau }_2\text{/}{\tau }_{\nu }\hspace{1em}=\hspace{1em}0.088$ [33].
