(Left) The slow relaxation time ${\tau }_q$ at which $f\left(q,{\tau }_q\right)=0.25$, defined as in Fig. 2, for the MD-simulated ISF (solid circles) and the DLS ISF (Fig. 2, Bottom) (open circles). (Right) Replotted data from Left, showing power-law dependence of ${\tau }_q$ on ${\varphi }_c-\varphi$, using $\gamma =2.8$ and the ${\varphi }_c^{\text{sim}}$ (MD) and ${\varphi }_c^{\text{exp}}$ (DLS) values reported in the text.
