"Shall we Take off the Caps?…": Yuri Andropov and Konstantin Chernenko
Данная статья является первой попыткой автора обратиться в рамках исследовательской парадигмы политической лингвистики к анализу автобиографического нарратива Ю. В. Андропова и К. У. Черненко.The given article looks at the analysis of self-portrait narrative of Yu. V. Andropov and K. U. Chernenko within the scientific paradigm of political linguistics. The aim of the study is to show the strategy of reading and comprehension of autobiography of a political leader as a communicative role act authorizing his self-consciousness and self-representation. The paper argues that the creation of a political narrative is determined by the main factor: the political leader is a diegetic narrator in the history of the country

Transformation of twinned Ni52.0Mn24.4Ga23.6 martensite in a rotating magnetic field: Theory and experiment
The influence of a rotating magnetic field on disk-shaped twinned Ni-Mn-Ga single crystals is studied theoretically and experimentally. A magnetoelastic model of ferromagnetic martensite is used for the comprehension of experimental results. The model considers the magnetic field influence on each twin component in terms of the magnetically induced mechanical stress (magnetostress). The angular dependence of magnetostress and the correspondence between the directions of the magnetic field and magnetization vector are obtained. The magnetically induced transformation of twin structure of the specimen is observed experimentally in a Ni52.0Mn24.4Ga23.6 single-crystalline disk by magnetic measurements performed in a two-dimensional vibrating sample magnetometer. The threshold character of the transformation process is stated. The threshold angles between the [100] crystallographic direction and the directions of magnetic field and magnetic vector of the transformed twin component were measured for the different magnetic field values. The comparison of experimental values with the theoretical ones points to the comparatively low value of the magnetic anisotropy constant (50 kJ m(-3)). The obtained results disclose the possibility of obtaining large magnetically induced strains in ferromagnetic-shape memory alloys with reduced magnetocrystalline anisotropy
Analysis of mechanical and magnetic instabilities in Ni-Mn-Ga single crystals
An analysis of mechanical and mechanic instabilities in Ni-Mn-Ga single crystals was carried out. Experimental stress-strain and magnetization versus field curves, measured for Ni2MnGa alloys were also compared with modeling results obtained using a statistical model. The results indicate that it is possible to evaluate the critical stress, which is necessary to overcome twin boundary pinning in a defined martensite structure

Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Magnetic anisotropies in Ni-Mn-Ga films on MgO(001) substrates
Ferromagnetic resonance was used to study the influence of temperature and film thickness on magnetic properties of Ni-Mn-Ga films deposited on single crystal MgO(001) substrates. It has been shown that depending on the film thickness and preparation condition, three configurations of magnetic anisotropy can be realized in these films. The temperature dependence of the anisotropy field is determined
