Equilibrium probability of the (a) and (c) translational and (b) and (d) rotational velocities of the nanoparticle in a stationary Newtonian fluid medium for ${\rho }^{(p)}\text{/}{\rho }^{(f)}\hspace{1em}=\hspace{1em}0.99$ ((a) and (b)) and $1.01$ ((c) and (d)). 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].
