We derive general expressions for the cross section of neutrino scattering on electrons in dense, hot stellar matter, in the presence of strong magnetic fields. Numerical calculations of the scattering cross sections at various densities, temperatures and magnetic fields, are performed. Strong, quantizing magnetic fields modify significantly the angular and energy dependence of the scattering c...

We match a few non chiral operators in the electric and magnetic descriptions of SQCD, suggesting the first evidence of electric-magnetic duality outside the chiral ring. Algebraically, these non chiral operators are a module of the chiral ring. Physically, the suggested correspondence essentially transforms certain electric gauge invariant composites containing the electric field strength into...

We follow the ambipolar-diffusion–driven formation and evolution of a fragment in a magnetically supported molecular cloud, until a hydrostatic protostellar core forms at its center. This problem was formulated in Paper I. We determine the density, velocity and magnetic field as functions of space and time, and the contribution of ambipolar diffusion and Ohmic dissipation to the resolution of t...

in order to investigate the soil magnetic susceptibility and its relationship with the concentration of selected heavy metals and soil properties, a total of 158 composite surface soil samples (0-5 cm) were taken from an area of about 700 km2. locations of the sampling sites were determined using a gps and their land uses were recorded. the in situ magnetic susceptibility for the topsoil sample...
