Cover Story: Darwinian evolution is grounded in a dynamical selection process that involves diverse classes of replicating agents. A self-consistent theory of evolution requires the incorporation of thermodynamics, particularly when dealing with early, prebiotic systems. Here, using a coarse-graining, nonequilibrium approach, we derive the entropy bounds for the three classes of Darwinian replicators, which effectively constrain the space of the possible replication strategies and their presence or absence.

The Volume of Two-Qubit States by Information Geometry

  • Milajiguli Rexiti,
  • Domenico Felice and
  • Stefano Mancini

24 February 2018

Using the information geometry approach, we determine the volume of the set of two-qubit states with maximally disordered subsystems. Particular attention is devoted to the behavior of the volume of sub-manifolds of separable and entangled states wit...

22 February 2018

Regression for count data is widely performed by models such as Poisson, negative binomial (NB) and zero-inflated regression. A challenge often faced by practitioners is the selection of the right model to take into account dispersion, which typicall...
