PHASE TRANSITION FOR GLUON FIELD: A QUALITATIVE ANALYSIS
01.00.00 Physical-mathematical sciences
DescriptionThe phase transition for US(3) gauge field (without quarks) is considered. It is shown that the phase transition is due to the fact that at high temperatures the partition function should be calculated as for a gas of gluons, whereas at low temperatures as the sum over energy levels of correlated quantum states of SU(3) gauge field. A correlated quantum state for strongly interacting fields is defined as a nonperturbative quantum state of strongly interacting fields. The energy spectrum of these quantum states are discrete one. A lower bound of the phase transition temperature by comparing of the average energy for the perturbative and nonperturbative regimes is estimated (for glueball being in thermal equilibrium with the thermostat). It is shown that this quantity is associated with a mass gap. In a scalar model of glueball its energy is calculated. It is shown that this energy is the mass gap. If we set the glueball mass ~ 1.5•10³MeV then it is found that the corresponding value of coupling constant lies in the nonperturbative region

THE ORIGIN OF INERTIAL MASS OBSEVABLE MATTER
01.00.00 Physical-mathematical sciences
DescriptionWe consider the hypothesis of the origin of mass of the observed matter from electromagnetic field interacting with streams of preons. The interaction between preons and the scalar and vector potentials of the electromagnetic fields acquire mass, which leads to a massive scalar and vector bosons. The described mechanism of mass generation is different from the well-known Higgs mechanism associated with the spontaneous breaking of the electroweak symmetry, for which at the moment is finding a suitable scalar boson

CLIMATIC CHANGES IN THE BLACK SEA REGION AND ELABORATION OF STRATEGY FOR ITS SUSTAINABLE DEVELOPMENT
01.00.00 Physical-mathematical sciences
DescriptionIn this article, we consider some aspects of regional development under changing climatic conditions. Further, we discuss trends and in global and regional climate in the past century and scenarios of climatic changes up to the end of the current century. The system of measures is suggested for transition to sustainable development of Russian Black Sea Coast. The conclusion is made that elaboration and correction of the regional sustainable development strategy requires wide spreading of information about climatic changes, environmental, economical and demographic conditions in the region

A MODEL FOR MINORITY CARRIER MOBILITY IN POLYSILICON EMITTERS
01.00.00 Physical-mathematical sciences
DescriptionA model for minority carrier mobility in polysilicon emitter contacts is developed. It is based on the effect of the segregation of electrically active dopants to polysilicon grain boundaries and the thermionic emission - diffusion theory of the hole current. An analytical equation is derived which allows to calculate hole mobility in polysilicon emitter contacts and its dependence on dopant concentration and polysilicon grain size

EMERGENCE PARAMETER OF CLASSICAL AND QUANTUM STATISTICAL SYSTEMS
01.00.00 Physical-mathematical sciences
DescriptionIn this article we give a generalization of Hartley's model for the measure of information. We propose a rate of emergence, which is applicable to systems obeying classical or quantum statistics. Quantum sys-tems that obey Fermi-Dirac statistics and Bose-Einstein condensate, as well as classical systems obey-ing the Maxwell-Boltzmann statistics have been con-sidered. We found that the emergence parameter of quantum and classical systems differ as well as the emergence parameter of quantum systems of fermions and bosons. Consequently, the emergence parameter might be used to distinguish the classical system and quantum system, as well as quantum system of fermions and the quantum system of bosons

MAIN FEATURES OF THE NEW PARADIGM OF MATHEMATICAL STATISTICS
01.00.00 Physical-mathematical sciences
DescriptionThe new paradigm of mathematical statistics is based on the transition from parametric to nonparametric statistical methods, the numerical data - to non-numeric, on the intensive use of information technology. Its distinctive features are revealed in comparison with the old paradigm of mathematical statistics in the mid-twentieth century

01.00.00 Physical-mathematical sciences
DescriptionCorrelation and spectral methods were used to analyze changes in the regime of air temperature and precipitation rate in the Black Sea region in the 20th century. It was established that climatic tendencies on the regional scale differed from the global ones. In order to predict their consequences in the nearest 10 to 20 years it is necessary to concentrate efforts on studying and modeling natural climatic variability, which superimposes on the relatively slow global changes
