The HADES experiment, installed at GSI, Darmstadt, measures di-electron production in A+A, p/π + N and p/π + A collisions. Here, the π and η Dalitz decays have been reconstructed in the exclusive p + p reaction at 2.2 GeV to form a reference cocktail for long-lived di-electron sources. In the C+C reaction at 1 and 2 GeV/u, these long-lived sources have been subtracted from the measured inclusiv...

Most notably we prove that for d = 1, 2 the classical Strichartz norm ‖ef‖ L 2+4/d s,x (R×Rd) associated to the free Schrödinger equation is nondecreasing as the initial datum f evolves under a certain quadratic heat-flow.

We prove Olĕınik-type decay estimates for entropy solutions of n × n strictly hyperbolic systems of balance laws built out of a wave-front tracking procedure inside which the source term is treated as a nonconservative product localized on a discrete lattice.

Using a correlation inequality of Contucci and Lebowitz for spin glasses, we demonstrate existence of the thermodynamic limit for short-ranged spin glasses, under weaker hypotheses than previously available, namely without the assumption of the annealed bound.

We obtain the best approximation in L 1 (R), by entire functions of exponential type, for a class of even functions that includes e −λ|x| , where λ > 0, log |x| and |x| α , where −1 < α < 1. We also give periodic versions of these results where the approximating functions are trigonometric polynomials of bounded degree.
