    Full text link
    We study the effective actions for massive rank-2 and rank-3 antisymmetric tensor field models in curved space-time. These models are classically equivalent to massive vector field and massive scalar field with minimal coupling to gravity respectively. We prove that effective action for massive rank-2 antisymmetric tensor field is exactly equal to one for massive vector field and effective action for massive rank-3 antisymmetric tensor field is exactly equal to one for massive scalar field. Prove is based on an identity for mass-dependent zeta-functions associated with Laplacians acting on pp-forms.Comment: 8 pages, REVTeX fil

    A theoretical study of the structural phases of Group 5B - 6B metals and their transport properties

    Full text link
    In order to predict the stable and metastable phases of the bcc metals in the block of the Periodic Table defined by groups 5B to 6B and periods 4 to 6, as well as the structure dependence of their transport properties, we have performed full potential computations of the total energies per unit cell as a function of the c/a ratio at constant experimental volume. In all cases, a metastable body centered tetragonal (bct) phase was predicted from the calculations. The total energy differences between the calculated stable and metastable phases ranged from 0.09 eV/cell (vanadium) to 0.39 eV/cell (tungsten). The trends in resistivity as a function of structure and atomic number are discussed in terms of a model of electron transport in metals. Theoretical calculations of the electrical resistivity and other transport properties show that bct phases derived from group 5B elements are more conductive than the corresponding bcc phases, while bct phases formed from group 6B elements are less conductive than the corresponding bcc phases. Special attention is paid to the phases of tantalum where we show that the frequently observed beta phase is not a simple tetragonal distortion of bcc tantalum

    The subject of the study is the institution of digital rights, which has recently been enshrined in Russian legislation. This topic is relevant since the definition of digital rights causes numerous discussions and disputes. Practice on this issue has not yet developed, and there are conflicts in the current legislation. The purpose of the article is to consider the scope of digital rights and define the category "digital rights", given that there is a deep difference between its broad and narrow definitions. The following tasks have been solved to achieve this goal: (1) to consider the regulatory framework governing digital rights; (2) to analyze the main approaches to the definition of digital rights; (3) to study various definitions of digital objects; (4) to highlight the main characteristics of digital objects; (5) to propose original definitions of "digital rights" and "digital objects".Methodology. The authors use the general scientific dialectical method, as well as formallegal, system-structural, formal-logical methods and methods of cognition. The synergetic method is used to clarify the main features of digital rights. It allows isolating new rules and reality from the creative potential of chaos.The main results and the scope of the study. Considering law as a variable phenomenon, it has been proved that it is constantly changing. Analysis allows the authors to conclude that digital rights are an independent special type of rights that arise only in relation to digital objects created in digital form. The features of digital rights include: digital format, occurrence only in the cyber-physical space, consolidation in the form of software algorithms, the accounting system is carried out without an intermediary, the owner’s digital rights are realized with access to the Internet and a key in the form of login.The main qualitative characteristics of digital objects include the following: digital objects are not material; in some cases, they cannot be materialized and there is no need for that; digital objects are created using modern high-tech systems; it is possible to make transactions with digital objects only in the cyber-physical space; the right of inheritance for some digital objects is limited to inheritance by will due to the peculiarities of ownership of these objects; digital objects can be disposed of without the participation of third parties and intermediaries; transactions with digital assets are confidential.Conclusions. Based on the study results, original definitions of "digital rights" and "digital objects" have been proposed. Digital right is a digital algorithm that enshrines the powers of individuals and legal entities to own, use, and alienate digital objects of civil rights in hightech systems, given that technical means provide the owner with the opportunity to exercise their powers. Digital objects represent an independent legal category, which is a cryptographic code that gives the owner the right to perform any actions with it - to own, dispose of, alienate, make transactions, and other actions not prohibited by law. Legislative amendments to the current Russian legislation are developed.Предметом исследования является институт цифровых прав в гражданском праве России. Цель статьи – рассмотреть объем цифровых прав и дать определение категории «цифровые права», учитывая, что между широким и узкоспециальным определением существует глубокое различие.

    Structural and magnetic properties of the (001) and (111) surfaces of the half-metal NiMnSb

    Full text link
    Using the full potential linearised augmented planewave method we study the electronic and magnetic properties of the (001) and (111) surfaces of the half-metallic Heusler alloy NiMnSb from first-principles. We take into account all possible surface terminations including relaxations of these surfaces. Special attention is paid to the spin-polarization at the Fermi level which governs the spin-injection from such a metal into a semiconductor. In general, these surfaces lose the half-metallic character of the bulk NiMnSb, but for the (111) surfaces this loss is more pronounced. Although structural optimization does not change these features qualitatively, specifically for the (111) surfaces relaxations can compensate much of the spin-polarization at the Fermi surface that has been lost upon formation of the surface.Comment: 18 pages, 8 figure

    Surface Properties of the Half- and Full-Heusler Alloys

    Using a full-potential \textit{ab-initio} technique I study the electronic and magnetic properties of the (001) surfaces of the half-Heusler alloys, NiMnSb, CoMnSb and PtMnSb and of the full-Heusler alloys Co2_2MnGe, Co2_2MnSi and Co2_2CrAl. The MnSb terminated surfaces of the half-Heusler compounds present properties similar to the bulk compounds and, although the half-metallicity is lost, an important spin-polarisation at the Fermi level. In contrast to this the Ni terminated surface shows an almost zero net spin-polarisation. While the bulk Co2_2MnGe and Co2_2MnSi are almost half-ferromagnetic, their surfaces lose the half-metallic character and the net spin-polarisation at the Fermi level is close to zero. Contrary to these compounds the CrAl terminated (001) surface of Co2_2CrAl shows a spin polarisation of about 84%.Comment: 14 pages, 6 figure

    THE ROLE OF MESOZOIC GEODYNAMIC EVENTS IN FORMATION OF SEDIMENTARY BASINS ON THE FRAMING OF THE EASTERN MONGOL-OKHOTSK OROGENIC BELT

    Get PDF
    The Mongol-Okhotsk orogenic belt, finally formed in the end of the Mesozoic as a result of later tectonic events, is divided into two flanks: western and eastern. Its formation is obviously due to a regular change in geodynamic events significantly obscured by late tectonic and magmatic processes in the western flank and more clearly defined in the eastern flank from both magmatic and stratified formations. The early changes in geodynamic environment are most clearly determined by the formation of magmatic complexes whose completion is usually accompanied by the strata formation. Stratons framing the eastern flank of the Mongol-Okhotsk orogenic belt in the Mesozoic were formed in sedimentary basins, which are currently isolated to the Krestovkinsky and Ogodzhinsky basins along the southern border and to the Strelkinsky, Malotyndinsky, Toromsky and Udsky basins along the northern border. The deposition environment varied from deep-sea marine to continental. The article attempts to correlate the cross-sections of sedimentary basins on the framing of the eastern Mongol-Okhotsk orogenic belt and considers similarity or difference in their structure, conditions of sedimentation, tectonic positions and dependence of their evolution on geodynamic processes in the regio

    DYNAMICS OF ORGANIC MATTER UNDER THE AFFORESTATION OF THE FORMER AGRICULTURAL SOD-PODZOLIC SOILS

    The dynamics of the organic matter of the chronosequence of sod-podzolic soils in the process of reforestation has been investigated using the granulo-densitometric fractionation.The objects of research were sod-podzolic soils of the chronosequence of abandoned areas, including the main stages of the development of secondary succession: from overgrowing by grass vegetation to zonal spruce forests of the specially protected natural territory of the Central Forest State Natural Biosphere Reserve. In the first 20–25 years after the reduction of agrocenosis, degradation changes of the humus state of sod-podzolic soils were observed, due to the lack of agrotechnological treatments and the lack of fresh organic matter (OM) of cultivated plants. It is shown that only after 50 years functioning in the reservoir regime, the qualitative and quantitative indicators of organic matter of sod-podzolic soils begin to approach those of spruce forests of different species composition over 100 years old. This is manifested in an increase in the amount of discrete OM, the level of carbon accumulation of this fraction of OM in the soil and the value of its share in the total carbon accumulation in the soil

    Objective of the study was to develop a method of assessment and forecasting of socio-economic damage inflicted by the outbreaks of infectious diseases using DALY index by the example of Crimean hemorrhagic fever. WHO expert-designed DALY index was adapted for use in the territory of the Russian Federation with due account of GDP values and age distribution among the population. Put forward was a scheme for prognostication of a possible social damage caused by infectious disease outbreak, expressed in the aggregate number of wasted years of productive life and economic loss resulted from GDP decrement. The method developed can be used for forecasting of socio-economic damage inflicted by the outbreaks of infectious diseases and evaluation of effectiveness as regards anti-epidemic and therapeutic interventions. Carried out has been assessment of economic and social losses which resulted from outbreaks of Crimean hemorrhagic fever in the Southern Federal District of Russia inclusive of the data on morbidity rates over the period of 1999-2010. Major economic damage is factored by the labor forces loss consequent to fatal cases of infection. Such a method of prognostication based on DALY index has been implemented in the territory of the Russian Federation for the first time ever
