Abstract:

We analyze Kudlik et al.'s recent criticism of the scaling procedure for the primary relaxation in supercooled liquids introduced by Dixon et al.. We find that those criticisms result from imposing unjustified constraints on the scaling procedure and from improper separation of the primary relaxation from other features in the spectrum.
