From coupled elementary units to the complexity of the glass transition
Supercooled liquids display fascinating properties upon cooling such as the
emergence of dynamic length scales. Different models strongly vary with respect
to the choice of the elementary subsystems (CRR) as well as their mutual
coupling. Here we show via computer simulations of a glass former that both
ingredients can be identified via analysis of finite-size effects within the
continuous-time random walk framework. The CRR already contain complete
information about thermodynamics and diffusivity whereas the coupling
determines structural relaxation and the emergence of dynamic length scales
Fitness, chance, and myths: an objective view on soccer results
We analyze the time series of soccer matches in a model-free way using data
for the German soccer league (Bundesliga). We argue that the goal difference is
a better measure for the overall fitness of a team than the number of points.
It is shown that the time evolution of the table during a season can be
interpreted as a random walk with an underlying constant drift. Variations of
the overall fitness mainly occur during the summer break but not during a
season. The fitness correlation shows a long-time decay on the scale of a
quarter century. Some typical soccer myths are analyzed in detail. It is shown
that losing but no winning streaks exist. For this analysis ideas from
multidimensional NMR experiments have been borrowed. Furthermore, beyond the
general home advantage there is no statistically relevant indication of a
team-specific home fitness. Based on these insights a framework for a
statistical characterization of the results of a soccer league is introduced
and some general consequences for the prediction of soccer results are
formulated.Comment: tex-file, 31 pages,16 figure
