Global in Time Solutions to Kolmogorov-Feller Pseudodifferential Equations with Small Parameter

The goal in this paper is to demonstrate a new method for constructing global-in-time approximate (asymptotic) solutions of (pseudodifferential) parabolic equations with a small parameter. We show that, in the leading term, such a solution can be constructed by using characteristics, more precisely, by using solutions of the corresponding Hamiltonian system and without using any integral representation. For completeness, we also briefly describe the well-known scheme developed by V.P.Maslov for constructing global-in-time solutions.Comment: 27 page

THEORETICAL CONCEPTION OF CLASSIFICATION OF CRIMES AGAINST MILITARYSERVICE ACCORDING TO THE EXISTING CRIMINAL LEGISLATION OF THE RUSSIAN FEDERATION

Objective: to implement a comprehensive theoretical analysis of the existing approaches to the definition of concept of crimes against military service, their nature, characteristics, classifications and types. Methods: dialectical approach to cognition of social phenomena, allowing to analyze them in historical development and functioning in the context of the totality of objective and subjective factors that determined the choice of the following research methods: systematic, formal-legal, analysis, synthesis, comparison.Results: on the basis of analysis of the norms of the Russian Criminal Code related to crimes against military service and the provisions of criminal and military criminal law doctrine, the author has developed and proposed a new classification of crimes against military service, depending on the object of crime.Scientific novelty: the article substantiates the fact that the classification of crimes against military service is conducted exclusively within the doctrine of criminal and military criminal law on the basis of various criteria: the direct object of crime, the victim, the objective aspect of crime, the subject of crime, the subjective aspect of crime, etc. At the same time, the author’s classification of crimes against military service is proposed, depending on the object of crimes under study: 1) crimes against the established order of statutory relations between servicepersons (Articles 332-336 of the Russian Criminal Code); 2) crimes against the established order of the general organization of military service (Articles 337-339 of the criminal code); 3) crimes against the established order of carrying out special services stipulated by military regulations (Articles340-344 of the Russian Criminal Code); 4) crimes against the established procedure for the treatment of military property (Articles 345-348 of the Russian Criminal Code); 5) crimes against the established procedure for the treatment of combat or potentially dangerous military equipment (Articles 349-352 of the Russian Criminal Code).Practical significance: the main provisions and conclusions of the article can be used in scientific, educational, legislative and law-enforcement activities

Review of the international dispute “Crimes of migration processes” held on 25 may 2018 by Saint Petersburg international criminological club

Objective to acquaint a wide range of readers with the problem of crime of modern migration processes and the views of Russian and foreign criminologists on it. Methods dialectical approach to the cognition of social phenomena determined the following research methods analysis synthesis comparison formallegal and comparativelegal methods. Results the article presents the main reports made at the International Scientific Conference S.M. Inshakov P.A. Kabanov H. Kuri V.N. Fadeev D.A. Shestakov and other scholars which affect the assessment of crime in the global migration processes today. The speakers present different views on the criminal component of migration processes in the modern society including the increased victimization of migrants as the least protected group of the population. The presentations expressed divergent views on the impact of migration on crime and victimization in society but the contradictions in the views of the speakers did not prevent the conclusion that states should pursue a balanced migration policy taking into account their own national interests. Scientific novelty the impact of migration processes on the state of crime and victimization in society was for the first time discussed at the meetings of the St. Petersburg International Criminological Club with the participation of representatives of foreign criminological organizations. As a result many criminological approaches have been established to the state migration policy aimed at reducing criminal activity and criminal victimization of migrants. The club meeting allows drawing the following conclusions a the impact of migration processes on various aspects of modern society is obvious. This impact is both positive as the natural redistribution of labor resources and negative increasing the criminality of social relations b to reduce the risks of criminalization of social relations the world community needs a unified coordinated migration policy c the causes of migration processes and the causes of crime are interrelated and interdependent. They feeding each other create an atmosphere of trouble and distrust in the state and public affairs. Practical significance the main provisions and conclusions of the review can be used in scientific educational law enforcement and lawmaking activities

Morphological stability diagram for slowly and rapidly solidifying binary systems

A linear morphological stability of the solid-liquid interface is analyzed for a binary alloy in the limit of low and high crystal growth velocities. Using the result of this analysis, a diagram of morphologies is derived for a whole range of solidification rates with indicating critical growth velocities for the transitions planar front ⇔ cellular/dendritic structure. It is specially noted that the speed of solute diffusion in the bulk liquid limits the absolute chemical stability velocity from the high-rate transition cells/dendrites ⇒ planar front. © 2020, The Author(s)

Dendritic to globular morphology transition in ternary alloy solidification

The evolution of solidification microstructures in ternary metallic alloys is investigated by adaptive finite element simulations of a general multicomponent phase-field model. A morphological transition from dendritic to globular growth is found by varying the alloy composition at a fixed undercooling. The dependence of the growth velocity and of the impurity segregation in the solid phase on the composition is analyzed and indicates a smooth type of transition between the dendritic and globular growth structures.Comment: 4 pages, 2 figure

Parity-violating nucleon-nucleon interaction from different approaches

Two-pion exchange parity-violating nucleon-nucleon interactions from recent effective field theories and earlier fully covariant approaches are investigated. The potentials are compared with the idea to obtain better insight on the role of low-energy constants appearing in the effective field theory approach and the convergence of this one in terms of a perturbative series. The results are illustrated by considering the longitudinal asymmetry of polarized protons scattering off protons, $\vec{p}+p -> p+p$, and the asymmetry of the photon emission in radiative capture of polarized neutrons by protons, $\vec{n}+p -> d+\gamma$.Comment: 31 page

Beam instabilities in Very Large Hadron Collider

The Very Large Hadron Collider (VLHC) is a supercon-ducting proton-proton collider with approximately 100 TeV cm and approximately 10{sup 34} s{sup -1}cm{sup -2} luminosity [1]. Currently, beam dynamics in this future accelerator is the subject of intensive studies within the framework of the US-wide VLHC R&D program. This presentation sum-marizes recent developments in the field. Besides general discussion on relevant VLHC parameters, we consider various beam instabilities and ways to avoid them. Finally, we outline possibilities for theoretical and experimental R&D

Alien Physicians and Their Admission into the United States

This Article discusses legislation passed by Congress in 1976 to drastically reduce the eligibility of alien physicians to enter the United States because of a fear of inferior medical services and a belief that such immigration was leading to a shortage of health care providers in some foreign nations. The article surveys the new requirements such as passing both medical and English competence examinations as well as obtaining individual labor certifications. The article goes on to discuss ways in which alien physicians can come to the Unites States without passing these examinations

Effectively Closed Infinite-Genus Surfaces and the String Coupling

The class of effectively closed infinite-genus surfaces, defining the completion of the domain of string perturbation theory, can be included in the category $O_G$, which is characterized by the vanishing capacity of the ideal boundary. The cardinality of the maximal set of endpoints is shown to be 2^{\mit N}. The product of the coefficient of the genus-g superstring amplitude in four dimensions by $2^g$ in the $g\to \infty$ limit is an exponential function of the genus with a base comparable in magnitude to the unified gauge coupling. The value of the string coupling is consistent with the characteristics of configurations which provide a dominant contribution to a finite vacuum amplitude.Comment: TeX, 33 page

Heating Structure of the Second Half of the XVIII Century (based on the archaeological materials of Tobolsk)

This study deals with description of the furnace structure, studied during archaeological work on the territory of the upper part of one of the oldest towns in Siberia – Tobolsk (founded in 1587). Stratigraphic surveys together with a numismatic collection allowed the authors to date the revealed heating structure to the second half of the XVIII century. It was established that the furnace was built at the bottom of the cellar; its base was a frame of scaffolds, on which the brickwork was made (the reuse of bricks from pulled down furnaces was recorded). The studied part of the furnace base has been preserved to a height of 1 m; the maximum studied dimensions are 170×160 cm. Based on the analysis of the masonry, the furnace found to be rectangular in shape. It was decorated with tiles. The authors believe that the studied furnace design is not typical for Tobolsk of the second half of the XVIII century. It was in the house of a wealthy citizen
