Scientists analyzed each element of the neutrino mass matrix belonging to leptons and showed theoretically that the intergenerational mixing of lepton flavors is large. Furthermore, by using the ...

Random matrices are used for the statistical analysis of large samples but find also application in various fields of physics. In particular they became of interest around 1990 in string theory as a ...

A well-known problem in numerical ecology is how to recombine presence-absence matrices without altering row and column totals. A few solutions have been proposed, but all of them present some issues ...
