Account of interactions in frameworks of Standard Model leads to appearence of γ5 terms in a dressed fermion propagator. In this case the standard spin projectors do not commute with propagator and should be modified. Starting point of our discussion is the eigenvalue problem for inverse propagator S(p). Having the solutions of this problem, one can understand the necessary modification of spin projectors. The same generalized spin projector appears at propagation of neutrino in a moving matter, but in contrast to vacuum case, corresponding polarization vector is not arbitrary. This spin projector commute with neutrino propagator and all dispersion laws for neutrino in media are classified according to spin projection onto this fixed axis.
A data life cycle (DLC) is a high-level data processing pipeline that involves data acquisition, event reconstruction, data analysis, publication, archiving, and sharing. For astroparticle physics a DLC is particularl...

We represent a new approach to the development and use of a subject-oriented heterogeneous distributed computing environment for solving large-scale problems of energy security research. Both the development of scalable applications (distributed applied software packages) and the computing resources integration are conducted using the Orlando Tools framework. It supports the collaborative application development based on the continuous integration of their software. Computation management tools in Orlando Tools are integrated with a multi-agent system. We propose special multi-agent tools for the heterogeneous resource allocation in the environment. These tools apply knowledge about the subject domain specifics of solved-problems and computing environment characteristics. The effectiveness of such management is highlighted by the results of solving practical problems of energy security research.

The article provides a technology for estimating of potential flooding areas in the lower pool of the irkutsk HPP at high mandatory water flow expenses through its water abstraction points, that probability has increased significantly since 2001, following the adoption by the Government of Russian Federation of a decree on strict control limits of Lake Baikal level within 456-457 m (in Pacific reference system). The article offers investigation on structure and method of digital modeling of the relief of the Angara river within 67 km in conditions of limited information (inaccuracy of the underwater and above-water relief).

Within the article, a technology is proposed for creating a geoportal for the collection and exchange of data between subject specialists. The technology is based on the developed model geoportal that implements common functions for many information systems. The technology significantly accelerates the creation of a subject-oriented geoportal that implements a ready-made set of various functions.

In the paper, we propose a new model of the natural gas market simulation. It takes into account the random nature of the natural gas demand that depends, for example, on temperature fluctuations during the heating period. The natural gas supplier strategy is optimized with the reservation of the necessary amount of fuel to compensate for demand fluctuations. To implement simulation modeling, we developed a scalable application with the DISCOMP framework. We apply DISCOMP to develop and use scalable applications in a heterogeneous distributed computing environment. The application significantly increases the number of model runs and improves the simulation accuracy in comparison with the Mathcad computations on a personal computer.
