BBGKY Hierarchy and Dynamics of Correlations

We derive the BBGKY hierarchy for the Fermi and Bose many-particle systems, using the von Neumann hierarchy for the correlation operators. The solution of the Cauchy problem of the formulated hierarchy for the case of a n-body interaction potential is constructed in the space of sequences of trace-class operators.Comment: 12 page

Збережена ідентичність у колективній дії соціальної групи (Agitated Identity in the Collective Action of a Social Group)

У статті розглянуто поняття “ідентичність”. Проаналізовано причини, що бентежать особистість у процесі ідентифікації. З'ясовано деякі обставини, які ускладнюють цей процес на сучасному етапі у суспільствах перехідного типу. Встановлено, що ідентифікація в сучасних умовах відбувається не з системою, цінностями чи традиціями, а з колективною дією окремих соціальних груп. (The notion “identity” is studied. The reasons that agitate the personality in the process of identification are analyzed. Some circumstances which complicate this process at the modern stage in the societies of transitional type are cleared out. It is ascertained that identification under the modern conditions takes place not with the system, values or traditions, but with the collective action of some social groups.

Thermal switching of indirect interlayer exchange in magnetic multilayers

We propose a magnetic multilayer layout, in which the indirect exchange coupling (IEC also known as RKKY) can be switched on and off by a slight change in temperature. We demonstrate such on/off IEC switching in a Fe/Cr/FeCr-based system and obtain thermal switching widths as small as 10--20~K, essentially in any desired temperature range, including at or just above room temperature. These results add a new dimension of tunable thermal control to IEC in magnetic nanostructures, highly technological in terms of available materials and operating physical regimes.Comment: 3 figures, Supplementary Inf

Ferromagnetic resonance and interlayer exchange coupling in magnetic multilayers with compositional gradients

Ferromagnetic resonance (FMR) in magnetic multilayers of type F1/f/F2, where two strongly ferromagnetic layers F1 and F2 are separated by a weakly magnetic spacer f with a compositional gradient along its thickness, is investigated. The method allows to detect the weak signal from the spacer in additional to the more pronounced and readily measured signal from the outer strongly-magnetic layers, and thereby study the properties of the spacer as well as the interlayer exchange interaction it mediates. Variable temperature FMR measurements, especially near the relevant Curie points, reveal a rich set of properties of the exchange interactions in the system. The obtained results are useful for designing and optimizing nanostructures with thermally-controlled magnetic properties.Comment: 6 pages, 3 figure

SME bonds in European countries as a new approach to financing

Nowadays a lot of new financial instruments for SMEs innovation projects are getting more popular in the business environment. A great number of them are traditional like credit loans at the same time we can observe the appearance of innovative ones. Variable set of financial instruments generalized on fig.1. This classification is giving by Organiztion of Economic Cooperation and Development ( OECD). As we can see from the fig.1 the classification is based on risk approach. For further research it is needed to сlarify these definitions. Firstly, asset based finance is the method of assigning structured turnaround capital and term loans, disbursement of debit portfolio, stocks, machines, funds, and / or real estate. This type of finding is suitable for SMEs beginners, refinancing existing loans, growth financing, mergers and acquisitions

Оцінна структура ономасіологічної парадигми «людина за ознакою її інтелектуальних характеристик» (EVALUATIVE STRUCTURE OF THE ONOMASIOLOGICAL PARADIGM «HUMAN BEING ON THE BASIS OF ITS INTELLECT»)

Стаття присвячена вивченню аксіологічної специфіки лексичних і фразеологічних одиниць номінаційної сфери «людина за ознакою її інтелектуальних характеристик» в англійській, чеській, українській та російській мовах. Проведено аналіз оцінної структури ономасіологічної парадигми. Систематизовано групи номінантів на позначення інтелекту людини відповідно до їх структурних та граматико-функціональних особливостей. (The phenomenon of human intelligence and its reflection in the vocabulary and phraseology attracted attention of linguists from different countries. There are a lot of studies devoted to semantic, pragmatic, motivational, axiological and other aspects of this problem. These researches were conducted with a view to conceptology, cultural linguistics, ethnolinguistics (O. L. Berezovich, І. M. Malіnіna, Ju. O. Pis’menna, O. V. Burusіna, L. B. Nіkіtіna, L. M. Steblin- Rudjakova), paremiology (N. P. Potapova, T. V. Leont’єva, T. V. Balaushhenko, A. P. Djus’kіna, N. G. Med), contrastive linguistics (O. M. Morozova, N. D. Tkachenko, M. A. Sokolova, Fan Dzin) etc. But there are several uncertain moments in this issue and they still require their solution. That is why axiological analysis of language units which designate intellectual characteristics of a person is still topical. This research deals with the axiological specific character of lexical and phraseological units which designate intellectual characteristics of a human being in English, Czech, Ukrainian and Russian languages. The main task of this article is analysis and systematization of the evaluative structure of onomasiological paradigm «human being on the basis of its intellect» and its semantic and grammatical special features. Suggested approach removes a whole number of questions during axiological analysis and allows conducting full-scale description of any conceptual fragment in any language.
