The author reviews the basic types of digital document content protection from unauthorized access and dissemination applied by publishers and book trading companies. The principles of digital rights management (DRM) while accessing digital documents. The author suggests that DRM systems are efficient to be applied to certain types and formats of digital documents in libraries and archives. He also reviews several commercial solutions for DRM-systems plied to the most popular PDF-format and substantiates the importance of DRM-systems standardization for digital document friendliness both for the users and rights holders disseminating digital publications. Existing and newly introduced international standards for DRM-systems are discussed. The typology of digital rights protection software as provided for by the standards is presented along with regulated DRM-system features based on data coding. Readium project by international non-profit Readium Foundation exemplifies standard approach to DRM-system design. The project goal is to develop software modules to integrate standard DRM-technology into computer information systems including ALIS.ΠΡΠ΅Π΄ΡΡΠ°Π²Π»Π΅Π½Ρ ΠΎΡΠ½ΠΎΠ²Π½ΡΠ΅ Π²ΠΈΠ΄Ρ Π·Π°ΡΠΈΡΡ ΡΠΎΠ΄Π΅ΡΠΆΠΈΠΌΠΎΠ³ΠΎ ΡΠ»Π΅ΠΊΡΡΠΎΠ½Π½ΡΡ

The author examines prospects for applying the full-range standard functionalities of automatic proximity identification systems. He discusses their performance capabilities for unique identification of library documents in the library information systems of different scaling plateau; using standards library standard identifiers in non-library information systems; the functionality of automatic proximity identification systems for library automation. The RFID technology plays the key role in developing automatic proximity identification. The library application features are examined from the viewpoint of harmonization with international and RF standards of automatic proximity identification systems. Developing the Internet of things concept gives into a new communication environment emerging based on the automatic proximity identification. This technology's standard capabilities may significantly expand the functionality of library automation. Integration of library information systems with global automatic identification systems is on agenda which is evidenced by the logic of development of information systems and library RFID.The article is written within the framework of the State Order β 730000F.99.1.BV09ΠΠ00006.ΠΠ·Π»ΠΎΠΆΠ΅Π½Ρ Π²ΠΎΠΏΡΠΎΡΡ ΡΠ°Π·Π²ΠΈΡΠΈΡ Π±ΠΈΠ±Π»ΠΈΠΎΡΠ΅ΡΠ½ΡΡ

Conformational transitions of heteropolymers in dilute solutions
In this paper we extend the Gaussian self-consistent method to permit study
of the equilibrium and kinetics of conformational transitions for
heteropolymers with any given primary sequence. The kinetic equations earlier
derived by us are transformed to a form containing only the mean squared
distances between pairs of monomers. These equations are further expressed in
terms of instantaneous gradients of the variational free energy. The method
allowed us to study exhaustively the stability and conformational structure of
some periodic and random aperiodic sequences. A typical phase diagram of a
fairly long amphiphilic heteropolymer chain is found to contain phases of the
extended coil, the homogeneous globule, the micro-phase separated globule, and
a large number of frustrated states, which result in conformational phases of
the random coil and the frozen globule. We have also found that for a certain
class of sequences the frustrated phases are suppressed. The kinetics of
folding from the extended coil to the globule proceeds through non-equilibrium
states possessing locally compacted, but partially misfolded and frustrated,
structure. This results in a rather complicated multistep kinetic process
typical of glassy systems.Comment: 15 pages, RevTeX, 20 ps figures, accepted for publication in Phys.

Agro-industrial complex of the Russian Federation as an indicator of Russiaβs readiness for an innovation breakthrough
Agriculture is a critical sector for the economy of any state, because it is the lifeblood of many other industries. The article provides an indicative analysis of the of the Russian economy readiness to enter the growth phase of the sixth technological order. The research is based on the postulate of the theory of long waves by N.D. Kondratyev, according to which the monitoring of innovation in the agricultural sector allows obtaining indicators of the phase of the economic cycle. The paper provides an assessment of the innovative development of world agriculture for compliance with global technological trends. The main indicators of innovation and economic growth in dynamics over the past few years are considered. The investment process specificity in countryβs agri[1]cultural production due to geographical, logistic and economic factors, that leads to a high capital intensity of innovations in the industry, has been revealed. The main problem in the investment attractiveness of the industry is the low demand among farmers for research and development results due to their high cost, which forms the extensive nature of investments in the industry and their low profitability. Low efficiency of research and development financing in the industry is due to investments in basic research that is not demanded by the market. The reason for this phenomenon is explained by ageing of intellectual capital in the industry and the lack of institutional tools for its activation: low wages, lack of clear tools for managing innovation in the industry. Possible solutions to problems of the agriculture innovative development and increasing the agricultural sector attractiveness for investors are given
