This paper reviews the Super-exponential algorithm proposed by Shalvi and Weinstein for blind channel equalization. We show that the algorithm coincides with a gradient search of a maximum of a cost function, which belongs to a family of functions very relevant in blind channel equalization. This family traces back to Donoho’s work on minimum entropy deconvolution, and also underlies the Godard...

A Bayesian analysis of a skewed exponential power distribution has been performed. The skewed exponential power family includes the symmetric exponential power distribution as a particular case and provides flexible distributions with lighter and heavier tails compared to the normal one. The distributions of this family can successfully handle both symmetry/asymmetry and light/heavy tails simul...

In this work we develop a microscopic physical model of early evolution where phenotype--organism life expectancy--is directly related to genotype--the stability of its proteins in their native conformations-which can be determined exactly in the model. Simulating the model on a computer, we consistently observe the "Big Bang" scenario whereby exponential population growth ensues as soon as fav...
