  Time-dependent dynamical properties of a fluid can not be estimated from a
single configuration without performing a simulation. Here we show, however,
that the scaling properties of both structure and dynamics can be predicted
from a single configuration. The new method is demonstrated to work very well
for equilibrium dynamics of the Kob-Andersen Binary Lennard-Jones mixture.
Furthermore, the method is applied to isobaric cooling where the liquid falls
out of equilibrium and forms a glass, demonstrating that the method requires
neither equilibrium nor constant volume conditions to work, in contrast to
existing methods.
