  The authors study the short-time dynamics of helix-forming polypeptide chains
using an all-atom representation of the molecules and an implicit solvation
model to approximate the interaction with the surrounding solvent. The results
confirm earlier observations that the helix-coil transition in proteins can be
described by a set of critical exponents. The high statistics of the
simulations allows the authors to determine the exponents values with increased
precision and support universality of the helix-coil transition in homopolymers
and (helical) proteins.
