Query: Analysis of the Density of Partition Function Zeroes - A Measure for
  Phase Transition Strength   We discuss a numerical analysis employing the density of partition function
zeroes which permits effective distinction between phase transitions of first
and second order, elucidates crossover between such phase transitions and gives
a new way to measure their strengths in the form of latent heat and critical
exponents. Application to a number of models demonstrates the efficacy of the
technique.
