    • Nonlinear Analogue of the May-Wigner Instability Transition 

      Fyodorov, YV; Khoruzhenko, BA (PNAS, 2016-01)
      We study a system of $N\gg 1$ degrees of freedom coupled via a smooth homogeneous Gaussian vector field with both gradient and divergence-free components. In the absence of coupling, the system is exponentially relaxing ...
    • Population genetics and substitution models of adaptive evolution 

      dos Reis, M (2013-11-26)
      The ratio of non-synonymous to synonymous substitutions $\omega(=d_{N}/d_{S})$ has been widely used as a measure of adaptive evolution in protein coding genes. Omega can be defined in terms of population genetics parameters ...
