Isothiocyanates comprise the most promising class of chemopreventive phytochemicals. They are encountered at substantial amounts in cruciferous vegetables where they exist in the form of glucosinolates. Epidemiological studies have linked consumption of isothiocyanates to low cancer incidence at a number of sites. Furthermore, laboratory studies in animal models of cancer have established that ...

The density corrections, in terms of the isospin chemical potential μI , to the mass of the pions are investigated in the framework of the SU(2) low energy effective chiral invariant lagrangian. As a function of temperature and μI = 0, the mass remains quite stable, starting to grow for very high values of T , confirming previous results. However, the dependence for a non-vanishing chemical pot...

Lattice QCD at finite chemical potential is difficult due to the sign problem. We use stochastic quantization and complex Langevin dynamics to study this issue. First results for QCD in the hopping expansion are encouraging. U(1) and SU(3) one link models are used to gain further insight into why the method appears to be successful.
