    Electron (positron) beam polarization by Compton scattering on circularly polarized laser photons

    Full text link
    In a number of papers an attractive method of laser polarization of electrons (positrons) at storage rings or linear colliders has been proposed. We show that these suggestions are incorrect and based on errors in simulation of multiple Compton scattering and in calculation of the Compton spin-flip cross sections. We argue that the equilibrium polarization in this method is zero.Comment: 11 pages, LaTeX, talk at 9-th Intern. Workshop on Linear Colliders (LC02), Feb. 4-8, 2002, SLAC, Stanford, US

    The problem of providing an integrated scientific, methodological and information support of the innovation process, covering all its stages including the creative phase, at which novelties are created (solving the problem of conceptual design), is considered. The generic heurorithm (heuristic algorithm) of the innovation management serves as the methodological basis for the implementation of the information support and management innovation system. It is a standard program tool for corporative innovation infrastructure for use in universities, and is intended for describing, accounting and management of ideas at different stages of the innovation cycle. Heurorithm has a modular structure and is represented by a graphical notation systems working schemes. Its schemes reflect a variety of means to support innovation: scientific and methodological support, methods, instructional materials, information resources and a program toolkit (including components of information support and innovation management system). These means correspond to the heuristic components of activities and heuristic information facilities: weakly formalized creative processes and experience gained during their realization. Availability and detailing of heuristics generated and used at different stages of the innovation process for its intensification, is one of the main differences between the developed heurorithm and known organizational charts of innovative activity. On the basis of the generic heurorithm in the system of information support and innovation management an interactive navigator on the stages of the innovation process and means of its support is developed. The research was conducted at the financial support of the state e represented by the Ministry of Education and Science of the Russian Federation (the unique identifier of the research work RFMEFI57314X0007).peer-reviewe

    The relevance lies in the institutionalization of education in the new subjects of the Russian Federation (DPR, LPR, Zaporizhia, Kherson regions, the Republic of Crimea, the federal city of Sevastopol), as well as the processes of re-socialization, adaptation to the socio-cultural, political, value-ideological realities of Russian society, which affects the construction of the civic identity of school youth. Understanding the processes of formation of civic identity in the educational policy system in the context of the transformation of the political space allows identifying the mechanisms of actualization and transformation of identity. Тhe experience of the post-Soviet states, as well as the processes taking place in Russia today, enables making interesting theoretical generalizations and practical recommendations.Aim and Tasks. Identification and systematization of practices, mechanisms and technologies for the formation of civil identity of schoolchildren in new subjects in the educational policy system of the Russian Federation, determination of existing problems and barriers, identification of models of civil identity formation in the context of comparing the experience of Russia and the EAEU countries.Methods. The study uses a focus group interview with senior and middle school students living in the new territories of the Russian Federation, an expert interview with representatives of institutional structures involved in the processes of political socialization and implementation of identity policy, as well as the analysis of secondary data reflecting the processes of formation of civil identity in the EAEU countries.Results. As a result, the key practices of forming the civil identity of schoolchildren in the new subjects of the Russian Federation are revealed and systematized, barriers and problems of implementing educational policy in the system of forming civil identity are identified. The authors propose recommendations for improving the model of formation of the identity of schoolchildren in the new subjects of the Russian Federation. The article shows the difference between the model of formation of Russian civil identity in the new regions and the models of formation of civil identity used in the EAEU countries.Conclusions. The study revealed the existing contradictions that arise in the process of adaptation to a new educational and value-ideological model, manifested in the assimilation of new social norms and educational standards; the difference in the level of political education and the degree of involvement in civic activity of young people was noted. It is necessary to search for effective practices and technologies that contribute to building a consistent model of civic identity formation in the basic education system of new subjects of the Russian Federation. The EAEU member states can use the practical experience of civil identity formation in the education system of new subjects of the Russian Federation to improve their own models of civil identity formation

    Technical summary

    The Working Group III (WGIII) contribution to the IPCC's Fifth Assessment Report (AR5) assesses literature on the scientific, technological, environmental, economic and social aspects of mitigation of climate change. It builds upon the WGIII contribution to the IPCC's Fourth Assessment Report (AR4), the Special Report on Renewable Energy Sources and Climate Change Mitigation (SRREN) and previous reports and incorporates subsequent new findings and research. Throughout, the focus is on the implications of its findings for policy, without being prescriptive about the particular policies that governments and other important participants in the policy process should adopt. In light of the IPCC's mandate, authors in WGIII were guided by several principles when assembling this assessment: (1) to be explicit about mitigation options, (2) to be explicit about their costs and about their risks and opportunities vis-a-vis other development priorities, (3) and to be explicit about the underlying criteria, concepts, and methods for evaluating alternative policies. This summary offers the main findings of the report

    Analytical model for electromagnetic cascades in rotating electric field

    Full text link
    Electromagnetic cascades attract a lot of attention as an important QED effect that will reveal itself in various electromagnetic field configurations at ultrahigh intensities. We study cascade dynamics in rotating electric field analytically and numerically. The kinetic equations for the electron-positron plasma and gamma-quanta are formulated. The scaling laws are derived and analyzed. For the cascades arising far above the threshold the dependence of the cascade parameters on the field frequency is derived. The spectra of high-energy cascade particles are calculated. The analytical results are verified by numerical simulations.Comment: 14 pages, 10 figure
