(a) MDSC scan of ${\mathrm{A}\mathrm{s}}_{20}{\mathrm{S}\mathrm{e}}_{80}$ bulk glass; $T_G$ is defined as the inflexion point of ${\dot{H}}_{\mathrm{r}\mathrm{e}\mathrm{v}}$ while $T_A$ is the end point of the ${\dot{H}}_{nr}$ endotherm. (b) $T_A/T_G$ (●) and $T_K/T_G$ (▲) for Ge-Se glasses. Lines without symbols are HW predictions [1].
