Characteristic time ${\tau }_A$ and localization scale $u_A^2$ extracted from simulations data for the film (Left) and composite systems (Right) at the onset temperature $T_A$. For films, parameters are shown as a function of inverse thickness $h_g^{-1}$ at $T_g$, and for composites as a function of nanoparticle concentration ϕ. (Bottom) Values of α from the best fit to Eq. 4. Note that the variations of ${\tau }_A$, $u_A^2$, and α are all small.
