Centers of cyclotomic Sergeev superalgebras
No full textAbstractWe prove that the natural map from the center of the affine Sergeev superalgebra to the even center of any cyclotomic Sergeev superalgebra of odd level is surjective, hence that the even center of a cyclotomic Sergeev superalgebra of odd level consists of symmetric functions in the squares of its polynomial generators
The genesis of S.N. Sergeev-Tsenskii's Preobrazhenie Rossii
No full textSergei Nikolaevich Sergeev (pseudonym Sergeev-Tsenskii) was born in September, 1875 and died in December, 1958. The sixty years of his literary career, which encompassed such momentous political upheavals in the history of Russia, were witness also to the most varied developments
in literature, ranging from the experimentation of the Futurists to the enshrinement of Socialist Realism as the State literary Word. Such periods of change demand commitment to one or another political grouping or literary mode. It is rare to find a Russian writer whose life spanned these turbulent decades that could state in 1945: "I never belonged to any groupings of writers nor took part in any circles,"¹
Curiosity is further aroused when the writer is praised by such disparate critics as M. Gor'kii, R. Ivanov-Razumnik and G. Struve. In 1924, Gor'kii called the novel Valia ". . . the finest book of all that have appeared in Russia during the last twenty-four years."² In an open letter to Romain Rolland published in Pravda in 1928, Gor'kii stated that ". . .at this time in the forefront of Russian literature stand two absolutely wonderful masters. They are Sergeev-Tsenskii and M. Prishvin."³ R. Ivanov-Razumnik includes the novels of Sergeev-Tsenskii in his list of the "summits" of Russian literature published after the Revolution.⁴ G. Struve writes that Sergeev-Tsenskii was "one of the outstanding representatives
of Neo-Realism in pre-Revolutionary literature...."⁵
Led to delve further into the career of Sergeev-Tsenskii, the student soon finds that his works were the centre of lively and controversial
critical interest in the decades preceding the Revolution, were
the subject of a spate of polemical articles spawned by the literary battles of the 1920's, were the cause of a spirited discussion of the genre of historical novels and of the fate of the fellow-traveller during the tightening controls of the 1930’s. Sergeev-Tsenskii became the recipient of high State honours in the early 1940's, only to fall into official disfavour in the late 1940's. By the mid-1950's he had managed
to stage a "come-back" and by the time of his death was regarded officially as one of the staples of Soviet literature.
In spite of his long and complicated career, no extensive studies of Sergeev-Tsenskii have been made by Western scholars; in fact, if he is mentioned at all in English-language histories of Russian or Soviet Russian literature, he is accorded only a few lines. During the last ten years, Soviet critics have published several monographs devoted, for the most part, to Sergeev-Tsenskii's post-1930 works. Recently his pre-Revolutlonary stories have become a source of renewed interest; several Candidate dissertations and scholarly articles dealing with this period of his career have been published.
A comprehensive review of all of Sergeev-Tsenskii's works is beyond the scope of my present study; I have chosen, therefore, to concentrate
on one large series of novels and short stories, the epopee,⁶ Preobrazhenie Rossii (Transformation of Russia). This cycle seemed an appropriate choice since it includes works written from 1910 to 1958 and ranges in genre from historical novels to stories set in contemporary Soviet Russia.
Since no biographical studies of Sergeev-Tsenskii are available in English, I have devoted the first chapter to a general outline of his life and works. In the second chapter I have attempted to
unravel the complicated history of the epopee during the forty-eight years of its development.
Soviet monographs on Sergeev-Tsenskii unroll to the reader an almost deja vue presentation of the development of the epopee and of his career. The peaceful transformation of a fellow-traveller to active proponent is somehow all too-familiar; no conflict has taken place, no reconsideration of previously-held convictions are revealed. However, the usual vague reference to a "complicated creative path" alerts the reader to the possibility
of thorns along the way. The placid picture depicted by Soviet critics of an author calmly observing and recording the events of the thirty years of Russian history described in the epopee turns out on closer investigation to be not entirely valid.
Textual comparisons of different editions of works in the epopee and examination of journal articles of the 1920's and 1930's brought to light a rather more tumultuous genesis of the epopee and revealed some of the "complications" in the creative path of Sergeev-Tsenskii. The publication
of one particular article in the journal Na literaturnom postu played an important role in the subsequent literary career of Sergeev-Tsenskii and in the development of the epopee, Preobrazhenie Rossii. In response to this article and the adverse criticism which was to follow, Sergeev-Tsenskii extensively revised parts of the epopee. This process is analysed in the third chapter of my study.Arts, Faculty ofCentral, Eastern, and Northern European Studies, Department ofGraduat
Gergo, folclore, turpiloquio in rima. Album per francobolli di A. Sergeev.
No full textL’articolo verte sulla traduzione dei versi tratti dal romanzo di Andrej Jakovlevič Sergeev (1933-1998) Al’bom dlja marok (Album per francobolli), insignito del prestigioso premio Booker russo nel 1996. In particolare ci si sofferma sulle problematiche traduttive legate ai versi presenti nel capitolo Semiletka con i loro giochi di parole, il "folclore scolastico", il gergo, il turpiloquio “in rima”. Sono tra le pagine linguisticamente più interessanti del libro, nonché quelle che pongono le sfide maggiori a livello traduttivo. E il lavoro di traduzione, nel complesso, ha seguito due criteri fondamentali: rifiutare qualsiasi “alibi” di intraducibilità e far sì che sopravvivesse l’effetto finale, così come desiderato dall’autore, sul lettore
A successful outcome of treatment in a patient with a spleen artery aneurysm complicated by bleeding in pseudocyst of the pancreas
No full text<p>A pseudoaneurysm is a rare and potentially dangerous vascular complication of acute pancreatitis, with a mortality of 20–43% in untreated patients. Its treatment includes embolization or surgical resection. A clinical case of a 39-year-old patient, with a history of chronic pancreatitis, pseudocyst of the tail of the pancreas, as well as a false aneurysm of the splenic artery detected by means of computed tomography of abdominal organs with contrast is presented. A two-stage surgical procedure was performed. The patient was discharged in a satisfactory condition. This case shows a successful use of diagnostic techniques, as well as a stage-by-stage approach to surgical treatment of this pathology.</p><p>Received 20 April 2017.

Transition from substorm growth to substorm expansion phase as observed with a radial configuration of ISTP and Cluster spacecraft
No full textInternational audienceTransition from the growth phase to the substorm expansion during a well-isolated substorm with a strong growth phase is investigated using a unique radial (THEMIS-like) spacecraft constellation near midnight, including the probing of the tail current at ~16 RE with Cluster, of the transition region at ~9 RE with Geotail and Polar, and of the inner region at 6.6 RE with two LANL spacecraft. The activity development on both a global scale and near the spacecraft footpoints was monitored with global auroral images (from the IMAGE spacecraft) and the ground network. Magnetospheric models, tuned using in-situ observations, indicated a strong tail stretching and plasma sheet thinning, which included the growth of the near-Earth current (approaching 30 nA/m2) and possible formation of a local B minimum in the neutral sheet (~5 nT) at ~10–12 RE near the substorm onset. However, there were no indications that the substorm onset was initiated just in this region. We emphasize the rather weak magnetic and plasma flow perturbations observed outside the thinned plasma sheet at Cluster, which could be interpreted as the effects of localized earthward-contracting newly-reconnected plasma tubes produced by the impulsive reconnection in the midtail plasma sheet. In that case the time delays around the distinct substorm onset are consistent with the activity propagation from the midtail to the inner magnetosphere. A peculiar feature of this substorm was that 12min prior to this distinct onset, a clear soft plasma injection to the GEO orbit was recorded which has little associated effects both in the ionosphere and in the transition region at ~9 RE. This pseudo-breakup was probably due to either a localized ballooning-type activity or due to the braking of a very narrow BBF whose signatures were also recorded by Cluster. This event manifested the (previously unknown) phenomenon, a strong tail overloading (excessive storage of magnetic energy) contrasted to the modest energy dissipation and plasma acceleration, which are both discussed and interpreted as the consequences of cold/dense and thick pre-substorm plasma sheet which often occurs after the long quiet period. The lessons of using the radial spacecraft configurations in substorm onset studies are also discussed. Keywords. Magnetospheric physics (Auroral phenomena, plasma sheet, storms and substorms
Lattice Paths and a Sergeev-Pragacz Formula for Skew Supersymmetric Functions
No full textAbstractWe obtain a new version of the Sergeev–Pragacz formula for supersymmetric functions of standard shape–one applicable to arbitrary skew shape. The result involves an antisymmetrized sum of determinants that are themselves flagged supersymmetric functions. The proof is combinatorial, and follows by means of lattice path transformations.</jats:p
Ansatz of Hans Bethe for a two-dimensional lattice Bose gas
No full textThe method of q-oscillator lattices, proposed recently in Bazhanov and Sergeev 2005 (Preprint hep-th/0509181), provides the tool for a construction of various integrable models of quantum mechanics in (2 + 1)-dimensional spacetime. In contrast to any one-dimensional quantum chain, its two-dimensional generalizations---quantum lattices---admit different geometrical structures. In this paper, we consider the q-oscillator model on a special lattice. The model may be interpreted as a two-dimensional lattice Bose gas. The most remarkable feature of the model is that it allows the coordinate Bethe ansatz: the p-particles' wavefunction is the sum of plane waves. Consistency conditions is the set of 2p equations for p one-particle wave vectors. These 'Bethe ansatz' equations are the main result of this paper.

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
