Kratkoe načertanie teorii izjaščnoj slovesnosti
Die Literaturwissenschaft hat A.F. Merzljakov bis in jüngste Zeit auffallend stiefmütterlich behandelt. Die Vorlage des "Kratkoe načertanie teorii izjaščnoj slovesnosti" soll zu einem besseren Verständnis Merzljakovs beitragen. Die vorliegende Ausgabe "Kratkoe načertanie teorii izjaščnoj slovesnosti v dvueh častjach", M. 1822, ist die Übersetzung der Einleitung und Poetik von Eschenburgs "Entwurf einer Theorie und Literatur der schönen Redekünste"

Propagation of sausage soliton in the solar lower atmosphere observed by Hinode/SOT
Acoustic waves and pulses propagating from the solar photosphere upwards may
quickly develop into shocks due to the rapid decrease of atmospheric density.
However, if they propagate along a magnetic flux tube, then the nonlinear
steepening may be balanced by tube dispersion effects. This may result in the
formation of sausage soliton. The aim of this letter is to report an
observational evidence of sausage soliton in the solar chromosphere. Time
series of Ca II H line obtained at the solar limb with the Solar Optical
Telescope (SOT) on the board of Hinode is analysed. Observations show an
intensity blob, which propagates from 500 km to 1700 km above the solar surface
with the mean apparent speed of 35 km s. The speed is much higher than
expected local sound speed, therefore the blob can not be a simple pressure
pulse. The blob speed, length to width ratio and relative intensity correspond
to slow sausage soliton propagating along a magnetic tube. The blob width is
increased with height corresponding to the magnetic tube expansion in the
stratified atmosphere. Propagation of the intensity blob can be the first
observational evidence of slow sausage soliton in the solar atmosphere.Comment: 5 pages, 4 figures, accepted in MNRA
EXPERIENCE OF REMOTE ANALYSIS OF THE IMPLEMENTATION OF CLUSTER POLICY IN REGIONAL AND SECTORAL ASPECTS
The article is written based on research in the framework of the Presidium of theRussianAcademyof Sciences' «Forecast Technological Development of Russia in view of new global integration processes, technological, economic and institutional aspects». The aim of the study was to develop and test a sociological tools remote monitoring implementation of cluster policy. The work was conducted by the authors in three stages: 1. Development of a methodology for analyzing and methods of remote sensing of primary information (2012); 2. Analiz source database on 83 regions of the country and on the oil and gas industry (2013); 3. Proverka fi ndings and conclusions based on the online survey of experts (2014). The paper presents the main results of this work at each stage of this work and concludes the possibility of using this methodology is not only scientifi c, but also for practical purposes

Целью исследования была разработка и апробирование социологического инструментария дистанционного контроля осуществления кластерной политики. Работа проводилась авторами в три этапа: 1. Разработка методологии анализа и методики дистанционного сбора первичной информации (2012); 2. Анализ исходной базы данных по 83 регионам страны и по нефтегазовой отрасли (2013); 3. Проверка полученных данных и выводов на основе онлайн опроса экспертов (2014). В статье представлены основные результаты этой работы по каждому этапу этой работы и делается вывод о возможности использования данной методологии не только в научных, но и в практических целях
Automorphism groups of polycyclic-by-finite groups and arithmetic groups
We show that the outer automorphism group of a polycyclic-by-finite group is
an arithmetic group. This result follows from a detailed structural analysis of
the automorphism groups of such groups. We use an extended version of the
theory of the algebraic hull functor initiated by Mostow. We thus make
applicable refined methods from the theory of algebraic and arithmetic groups.
We also construct examples of polycyclic-by-finite groups which have an
automorphism group which does not contain an arithmetic group of finite index.
Finally we discuss applications of our results to the groups of homotopy
self-equivalences of K(\Gamma, 1)-spaces and obtain an extension of
arithmeticity results of Sullivan in rational homotopy theory
Propagation of Long-Wavelength Nonlinear Slow Sausage Waves in Stratified Magnetic Flux Tubes
The propagation of nonlinear, long-wavelength, slow sausage waves in an expanding
magnetic flux tube, embedded in a non-magnetic stratified environment, is discussed.
The governing equation for surface waves, which is akin to the Leibovich–Roberts
equation, is derived using the method of multiple scales. The solitary wave solution of the
equation is obtained numerically. The results obtained are illustrative of a solitary wave
whose properties are highly dependent on the degree of stratification
