We consider a generalized statistical mechanics model for the creation process of cosmic rays which takes into account local temperature uctuations. This model yields Tsallis statistics for the cosmic ray spectrum. It predicts an entropic index q given by q = 11 9 at largest energies (equivalent to

The property of isoscaling in nuclear fragmentation is studied using a simple bond percolation model with ''isospin'' added as an extra degree of freedom. It is shown, first, that with the assumption of fair sampling and with homogeneous probabilities it is possible to solve the problem analytically
We generalize classical statistical mechanics to describe the kynematics and the dynamics of systems whose variables are constrained by a single quantum postulate (discreteness of the spectrum of values of at least one variable of the theory). This is possible provided we adopt Feynman's suggestion
