Writing the Time of Troubles, False Dmitry in Russian Literature (Book Review)
No full textThis book discusses the Time of Troubles (Smutnoe vremya) period and the pretenders who appeared after the killing of Ivan the Terrible’s legal heir, Ivan, leaving the Empire without leadership. The power struggle began immediately after the death of Tsar Ivan which brought the Rurikid dynasty to an end; rival boyars created a weak government and autocracy. The book discusses these issues and the representations of Dmitry, the son of Ivan the Terrible within the context of Russian literature. The absence of legitimate royal authority after the demise of the Rurikid dynasty in 1598 caused a dynastic crisis. This period known as the Time of Troubles was characterized by a dynastic struggle that nearly resulted in the shattering of the Muscovite state. It finally came to an end in 1613 with the appearance of the new dynasty, the Romanovs. The book consists of six chapter. In the Introduction the author states that she will examine the “protagonist”, Dmitry, within the context of Russian literature. She examines Dmitry both as a literary figure and a real historical one, and describes Dmitry as a “tabula rasa” because he died under mysterious circumstances with no credible witnesses to confirm how he died. In her book, the author conducts her research both chronologically and diachronically. Chapter I is an introductory chapter that provides information on the eighteenth and nineteenth-century Russian texts Tulupov’s Life of St. Dmitry, The Story of Grishka Otrepev and Tale of Recovery that illustrate the prehistory of Dmitry. The author compares seventeenth century text types and arrives at the conclusion that all three works express a political message and that all of them contain a hagiographical structure and explication. Chapter II examines Russia’s historical experience in the eighteenth century and its literary tradition. In this chapter, the author examines Sumarokov’s tragedy Dmitry the Pretender and Narezhny’s Dmitry the Pretender. The author compares the main causes of his usurpation and its interpretation in literary works of the seventeenth century and the eighteenth century, and concludes that the writers of the seventeenth century crafted quasi-literary, polemical, monological interpretations of the period and determined who was the sole man qualified to rule. Prose treatments of the Dmitry material were the most appropriate way to shape their literature. Eighteenth century writers, on the other hand, recognized a large number of candidates to the throne and their interpretation of the period was multifaceted; tragedy was the most popular literary genres. In Chapter III, the author examines the body of works discussing Dmitry and the Time of Troubles in the 1820s and 1830s: Alexander Pushkin’s Comedy about Tsar Boris and Grishka Otrepev, Faddey Bulgarin’s Dmitry the Pretender, Alexey Khomyakov’s Dmitry the Pretender, Mikhail Pogodin’s Historical Portrait of Dmitry the Pretender. She states that the writers of Russia’s early nineteenth century were fascinated with the Dmitry materials, and each writer depicted him as a man who lived among others and saw him as an alternative to the reigning autocracy. However, they later arrived at the conclusion that there was no viable alternative to the reigning autocracy. Chapter IV deals with two plays written in response to the Era of Great Reforms in 1866: Alexander Ostrovsky’s Dmitry the Pretender and Vasily Shuisky and Nikolay Chaev’s Dmitry the Pretender. She criticizes both authors’ works on a number of fronts, regarding all of them as being overly ambitious in that they attempt to treat too many unrelated issues, and that the miscellaneous political issues raised in these dramatic works have no clear connection to one another. In the Chapter V, the author states that Dmitry disappears from Russian novels and plays for a century and reappears after the demise of the Soviet Union. She examines Daniil Mordovtsev’s False Dmitry: A Historical Novel of the Time of Troubles, Vasily Avenarius’s In Service to the Tsarevich, Nikolay Alekseev’s The False Tsarevich and Alexey Suvorin’s Tsar Dmitry the Pretender and Tsarevna Xenya. The author concludes that each writer has presented his own interpretation of Dmitry and his era, that these works are clearly independent and any similarities among them are merely coincidental with no pattern to them. Since each writer has selected his own particular assortment of “facts”, the novels each follow their own unique line of development. On a more general note, the author argues that the collection of late nineteenth century works on the Time of Troubles should be interpreted in the context of both their local frame of reference and national pride in the country’s cultural heritage. However, in the Soviet period Dmitry’s disappearance was the result of the Soviets’ emphasis on shaping the nation’s future rather than linking present realities to the national past. In the Conclusion, the author points out that all of the works discussed simultaneously deal with two distinct periods in time – the time in which the works are set and the time in which they were composed. For seventeenth century writers, marking the passing of the old dynasty was important, but the establishment of a new dynasty was just as significant. In the two eighteenth century works that were examined, contemporary political issues were treated in the context of Dmitry’s era. Nineteenth century works more closely resemble seventeenth century works in that the contemporary relevance of the historical events these works deal with is their main focus. According to the author, as long as writers continue to deal with political issues in literature or the theater, the figure of Dmitry will remain a relevant character. This book is very well written source examining the Time of Troubles period, a period when there was no legal heir to run the state, when dynastic struggle began the process of bringing an end to the Rurik Dynasty and leading to a period pretenders. The author provides different interpretations for the “protagonist”, Dmitry, within the context of Russian literature. The author particularly examines different writers’ works in chronological order and discusses the legitimacy of Dmitry by comparing the treatments of the pretenders. This book should be of interest to anyone interested in the period of the Time of Troubles and usurpation and their interpretation in Russian literature
Outstanding Surgeon and Scientist Dmitry Alekseevich Arapov
No full textIn 2022, we are approaching 125 years since the birth of Dmitry Alekseevich Arapov, a prominent domestic surgeon, scientist, experimenter, organizer of the military medical services. Dmitry A. Arapov, one of the most prominent representatives of the S.S. Yudin scientific school, worked at the N.V. Sklifosovsky Research Institute for Emergency Medicine from 1929 till 1984. He quickly proved himself not only as an excellent doctor and a skilled surgeon, but also as a researcher, and soon became one of the closest students and associates of S.S. Yudin. Dmitry A. Arapov drafted as a field surgeon during the Soviet-Finnish war of 1939-1940, from the first to the last day he went through the Great Patriotic War, being the Head of the surgical service of the Northern Fleet in Polyarny. In this position, he significantly improved the system for providing emergency surgical care on ships and in naval hospitals, based on the experience gained over the years of work at the N.V. Sklifosovsky Research Institute for Emergency Medicine. From July 1950 Dmitry A. Arapov was Chief Surgeon of the USSR Navy, from May 1953 he was Deputy Chief surgeon of the Main Military Sanitary Directorate of the USSR Ministry of Defense, and from May 1955 again Chief Surgeon of the USSR Navy, until his retirement in October, 1968. At the same time, Dmitry A. Arapov did not leave his work at the N.V. Sklifosovsky Research Institute for Emergency Medicine until the last days of his life. Dmitry A. Arapov is the author of more than 200 research papers, including 14 monographs. Scientific interests of Dmitry A. Arapov went far beyond emergency surgery, to which he naturally paid most attention. His works are devoted to various issues of military and emergency surgery of the abdominal and thoracic organs, topical issues of burn injuries, surgical site infections, reconstructive surgery, neurosurgery, treatment of endocrine disorders, and anesthesiology and resuscitation. Also Dmitry A. Arapov successfully dealt with the problems of autotransfusion, blood reinfusion from the chest and abdomen, transfusion of fibrinolytic blood. The main directions of scientific research, laid down by Dmitry A. Arapov, are currently being continued at the Scientific Department of Emergency Surgery, Endoscopy and Intensive Care of the N.V. Sklifosovsky Research Institute for Emergency Medicine. Memory of Dmitry A. Arapov has been preserved to this day. To the 100th anniversary of the birth of D.A. Arapov, a scientific conference was held at our Institute. The naval hospital in the town of Polyarny, Murmansk region, was named after Dmitry A. Arapov, and in honor of D.A. Arapov, a memorial plaque was installed on its building. In the 70s of the twentieth century, People’s Artist of the USSR L.E. Kerbel created a sculpture of Dmitry A. Arapov, which was stored in the local history museum of the town of Polyarny. His bust portrait (by artist T.S. Smagina) is exhibited at the Scientific Department of Emergency Surgery, Endoscopy and Intensive Care of the N.V. Sklifosovsky Research Institute for Emergency Medicine. In addition, the N.V. Sklifosovsky Research Institute for Emergency Medicine owns an earlier portrait of Dmitry A. Arapov by artist F.S. Bulgak. We introduce these portraits into scientific circulation for the first time. We are confident that they will be able to tell contemporaries a lot about this scientist, surgeon and man who made a great contribution to surgery and military medicine, and rightfully entered the history of Russian medicine

Aleksey Yakovlev and Dmitry Ulyanov (from the Family History of Yakovlevs and Ulyanovs)
No full textThe longstanding friendship between the Yakovlev and Ulyanov families is a wide-ranging topic. The
Ulyanov family has been thoroughly studied by historians, but the Yakovlevs did not enjoy comparable attention.
The most renowned of this last clan was Alexey Ivanovich Yakovlev, who kept up relations with Vladimir Lenin. But
in the light of archival materials and memoirs, one could claim that interfamily relations extended beyond familiarity
between these two individuals. The paper traces friendship between Alexey Ivanovich Yakovlev and Dmitry Il'ich
Ulyanov. These friendly terms lasted for decades, since the childhood of the confidants, who maintained warm
relations despite the circumstances and the vicissitudes of their fates. The source for the study of their friendship
is the correspondence between them. A number of letters from both have been published, and the rest are in the
Archive of the FSB Directorate of St. Petersburg and the Leningrad Region, in the investigative file of A. I. Yakovlev,
who was arrested during the “Academic Case” of 1929–1931. The correspondence between Dmitry Ulyanov
and Alexei Yakovlev began in 1893. Despite all the differences in their professional activity in the following years,
their friendship continued even after the Revolution, when A. I. Yakovlev became a famous historian, author of
several monographs, and a professor at Moscow University, and Dmitry Ulyanov held a number of high government
positions, including the head of the government of the Soviet Crimea. The last letter of their many years of
correspondence is dated 1943
Clustering-Based Identification of Precursors of Extreme Events in Chaotic Systems
No full textAbrupt and rapid high-amplitude changes in a dynamical system’s states known as extreme events appear in many processes occurring in nature, such as drastic climate patterns, rogue waves, or avalanches. These events often entail catastrophic effects, therefore their description and prediction is of great importance. However, because of their chaotic nature, their modelling represents a great challenge up to this day. The applicability of a data-driven modularity-based clustering technique to identify precursors of rare and extreme events in chaotic systems is here explored. The proposed identification framework based on clustering of system states, probability transition matrices and state space tessellation was developed and tested on two different chaotic systems that exhibit extreme events: the Moehliss-Faisst-Eckhardt model of self-sustained turbulence and the 2D Kolmogorov flow. Both exhibit extreme events in the form of bursts in kinetic energy and dissipation. It is shown that the proposed framework provides a way to identify pathways towards extreme events and predict their occurrence from a probabilistic standpoint. The clustering algorithm correctly identifies the precursor states leading to extreme events and allows for a statistical description of the system’s states and its precursors to extreme events.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Aerodynamic

Elena V. Kanishcheva – Cand. Sc. (Philology), Аssociate Рrofessor of the Department of Russian Language and Literature, South Ural State University (Chelyabinsk), e-mail: [email protected]Статья посвящена изучению актуального феномена старообрядческой литературы. Материалом исследования послужила старообрядческая сказка Дмитрия Урушева «Два брата», тематически продолжающая опубликованную ранее книгу «Звезда Альтаир». Актуальность работы подчеркивается также выбором материала, не становившегося ранее предметом специального литературоведческого анализа.
Цель исследования состоит в выявлении особенностей проявления религиозных мотивов в книге Дмитрия Урушева. В статье названы мотивы, традиционные для религиозной литературы: мотив поиска веры, мотив продажи души дьяволу, мотив самопожертвования, мотив спасительной молитвы. В ходе анализа автор выявляет центральный мотив произведения, который определяет художественные особенности текста, – идейное содержание сказки, сюжет произведения, систему образов персонажей. Важной особенностью книги Д. Урушева «Два брата» в исследовании названа авторская жанровая номинация, которая позволяет гармонично переплетать в художественной структуре сказочные и религиозные элементы, смешивать временные пласты, детали различных культур. The article is devoted to the study of the current phenomenon of Old Believer literature. The material of the study was the Old Believer fairy tale of Dmitry Urushev «Two Brothers», which thematically continues the previously published book «Star Altair». The relevance of the work is also emphasized by the choice of material that did not previously become the subject of special literary analysis.The purpose of the study is to identify the features of the manifestation of religious motives in the book of Dmitry Urushev. The article names the motives traditional for religious literature: the motive for finding faith, the motive for selling a soul to the devil, the motive for self-sacrifice, the motive for saving prayer. During the analysis, the author reveals the central motive of the work, which determines the artistic features of the text – the ideological content of the tale, the plot of the work, the system of images of characters.
An important feature of D. Urushevv’s book «Two Brothers» in the study is the author’s genre nomination, which allows you to harmoniously interweave fabulous and religious elements in the artistic structure, mix time layers, details of various cultures

W.N.B. acknowledges support from NSF grant AST-1108604 and the V. M. Willaman Endowment. KDD is supported by an NSF AAPF fellowship awarded under NSF grant AST-1302093.We explore the variability of quasars in the Mg ii and Hβ broad emission lines and ultraviolet/optical continuum emission using the Sloan Digital Sky Survey Reverberation Mapping project (SDSS-RM). This is the largest spectroscopic study of quasar variability to date: our study includes 29 spectroscopic epochs from SDSS-RM over 6 months, containing 357 quasars with Mg ii and 41 quasars with Hβ . On longer timescales, the study is also supplemented with two-epoch data from SDSS-I/II. The SDSS-I/II data include an additional 2854 quasars with Mg ii and 572 quasars with Hβ . The Mg ii emission line is significantly variable (Δƒ/ƒ ~ 10% on ~100-day timescales), a necessary prerequisite for its use for reverberation mapping studies. The data also confirm that continuum variability increases with timescale and decreases with luminosity, and the continuum light curves are consistent with a damped random-walk model on rest-frame timescales of ≳5 days. We compare the emission-line and continuum variability to investigate the structure of the broad-line region. Broad-line variability shows a shallower increase with timescale compared to the continuum emission, demonstrating that the broad-line transfer function is not a δ-function. Hβ is more variable than Mg ii (roughly by a factor of ~1.5), suggesting different excitation mechanisms, optical depths and/or geometrical configuration for each emission line. The ensemble spectroscopic variability measurements enabled by the SDSS-RM project have important consequences for future studies of reverberation mapping and black hole mass estimation of 1<픃<2 quasars.Peer reviewe
Klinickopatologické a molekulárně biologické charakteristiky vybraných kožních epiteliálních a neepiteliálních nádorů
No full textThe doctoral thesis MD. Liubov Kastnerova (previous name Kyrpychova) is focused on the histomorphological and molecular biologic features of selected cutaneous epithelial and nonepithelial tumors and is structured as a commentary to the 20 articles published during four years, representing the completed scientific projects in the Ph.D. course. In eight papers, the author of the thesis is the first author, whereas she coauthored in the remaining 12 papers. The thesis is composed of the commented files of authors own publications and it is divided into cutaneous epithelial and nonepithelial tumors. The first section, «Cutaneous epithelial tumors», includes 14 articles that are subdivided into two parts: adnexal tumors (9 articles) and lesions of anogenital mammary-like glands (5 articles). Of the nine articles on adnexal tumors, there are 5 articles focused on various benign and malignant adnexal lesions with apocrine or eccrine differentiation. Novel findings in this part include the identification of hitherto unreported alterations of the MYBL1 gene in adenoid cystic carcinoma of the skin and lack of deletion of the 1p36 locus in this neoplasm; the lack of a correlation between cellular composition and the presence CRTC1-MAML2 fusions in hidradenoma, the absence of CRTC3-MAML2 fusions in this tumor,...Disertační práce MD.
