Query: Partition Function Zeros and Finite Size Scaling of Helix-Coil
  Transitions in a Polypeptide   We report on multicanonical simulations of the helix-coil transition of a
polypeptide. The nature of this transition was studied by calculating partition
function zeros and the finite-size scaling of various quantities. Estimates for
critical exponents are presented.
