    Abstract: The mechanism of the appearance of neutron complexes, which at the final stage of their development, evolve into neutron stars, is described. It is shown that for a quantitative description it is necessary to use a generalization of the Newton-Schrödinger equations taking into account the next terms in the decomposition of explicit Dirac – Maxwell ...

    Abstract: In this study, the inter-comparison of various global vertical total electron contents are derived from Global Positioning System (GPS) networks worldwide. Based on observation data obtained from global network of dual frequency, the ionospheric variability on one full year, 2008 is studied through the vertical electron conten distribution GPS. The...
