Synthesis of Superheavy elements and Theory of Atomic Nucleus

The connection of synthesis of long-lived superheavy nuclei and existence of the island of stability with the choice of realistic nuclear potential is discussed: the behaviour of the average field of nuclei is an important element of nuclear models. It is also shown that it is just Dubna that possesses the priority both in the recent synthesis of a superheavy nucleus with charge Z=114 and in its theoretical prediction made 35 years ago. Possible sizes of the island of stability of superheavy nuclei are considered.Comment: 14 pages . Talk at the Intern.Symp.on Exotic Nuclei . Baikal Lake, July 24 -- 28, 200

Nuclear Scissors Mode with Pairing

The coupled dynamics of the scissors mode and the isovector giant quadrupole resonance are studied using a generalized Wigner function moments method taking into account pair correlations. Equations of motion for angular momentum, quadrupole moment and other relevant collective variables are derived on the basis of the time dependent Hartree-Fock-Bogoliubov equations. Analytical expressions for energy centroids and transitions probabilities are found for the harmonic oscillator model with the quadrupole-quadrupole residual interaction and monopole pairing force. Deformation dependences of energies and $B(M1)$ values are correctly reproduced. The inclusion of pair correlations leads to a drastic improvement in the description of qualitative and quantitative characteristics of the scissors mode.Comment: 36 pages, 5 figures, the results of calculation by another method and the section concerning currents are adde

Urzhumian stage in geochemical variations

Geological site Cheremushka is known as key stratigraphic record of Urzhumian stage of Middle Permian (Biarmian) series. It is situated on the Volga River's right bank, near Kazan city (Russia). In present paper lithology and geochemistry of this section is analyzed by EDXRF and discussed to reveal regional facial and cyclic features of the succession formed in altered sedimentary environments. Bulk geochemistry of sediments can be used to characterize the distribution of allogenic and authigenic components. It can also be used to compare these distributions with the general evolutionary stages of Volga River's region. The sedimentary sequence at site Cheremushka is divided into nine geochemical stages and sedimentary cycles using bulk geochemistry profiles, where silica change is considered as basic. The stage (cycles) boundaries correlate with the significant lithologic boundaries. Paleoenvironmental evolution is interpreted as alteration of lagoon and terrigenous flux influenced environments in arid climate during Sulitzkian time and in humid climate during Isheevskian time. © 2006-2014 Asian Research Publishing Network (ARPN)

Methodology for building extraction templates for Russian language in knowledge-based IE systems

In this paper we describe methodology for building information extraction (IE) rules. Rules are usually developed by experts and are widely used in knowledge-based IE systems. They consist of two parts: the left-hand side (LHS) of a rule is a template that matches a certain syntactico-semantic structure (SSS) and the right-hand side is an action that is executed when LHS template is matched against a particular text fragment. In the paper we describe the process of building a more complex LHS part (further in the paper we will refer to LHS as template). This methodology was used for developing the information extraction system that extracts business events from news articles written in Russian language. © Copyright 2012 Hewlett-Packard Development Company, L.P

Geochemical examination of the Middle-Upper Permian rocks, Volga river reference section

© 2006-2016 Asian Research Publishing Network (ARPN).The Middle-Upper Permian rocks, Volga river reference section, were geochemically examined by XRF analysis to reveal the Ural provenance, aridity and humidity levels, smectite-illite association as indicator of environmental change. Geochemical variations correlate with the regional lithostratigraphic scheme and cyclicity

Dictionary and pattern-based recognition of organization names in Russian news texts

This paper describes a part of the event extraction system which has been developed in collaboration with HP Labs Russia. The domain of input texts is business news feeds. One of the most important event participant types is 'Organization'. This paper is focused on the problem of organization names recognition in Russian news texts. Two approaches have been implemented. The first is dictionary-based. We propose an algorithm to make a dictionary from a set of legal body full names gathered from a government registry. The main problems with the dictionary matching are incorrect stemming and significant fraction of ambiguous names among dictionary entries. The second recognition approach is based on usage of local context clues and internal name words. These words constitute patterns which are intrinsic to organization names. These patterns enable recognition of non-dictionary names. We propose an algorithm to derive such patterns from the original dictionary. © 2013 Hewlett-Packard Development Company, L.P
