    • All the DRTs presented henceforth are chosen among almost identical in terms of spectral characteristics (number, location, and shape of the peaks) solutions for F(In(τ)) [see Eq. (1)] possessing the minimum degree of information (i.e., number of peaks) absolutely necessary to describe the data.

    • It is a current issue of scientific debate whether the picture of the so-called "heterogeneous" or "homogeneous" scenario is more appropriate for the description of dynamics in the local segmental scale [see, for instance, Richter et al., Phys. Rev. Lett. 82, 1335 (1999), and references therein]. Here, we essentially adopt the heterogeneous picture, where local relaxation processes are expressed as a superposition of single exponentials, weighted by a distribution of relaxation times F(In(τ)).
