Discovering the Far East...’: Images of the Territory in the Works of V. K. Arsenyev

The article explores the works of the Far East explorer V.K. Arsenyev (1872–1930) with the purpose of using his works to find the representational potential of the region’s image. Using social constructivism as a methodology, we outline and analyze scientific and artistic types of constructing the Far East image and demonstrate the place each of these types occupies in Arsenyev’s works.     Keywords: regional image, constructivism, construct, visualization, Russian Far East, V.K.Arsenye

Soviet Anti-religious Film. “Sectarians” by Vladimir Korolevich (1930)

The article examines a unique phenomenon of Soviet cinema – the anti-religious film of the 1920s–1930s – a question insufficiently explored in humanitarian historiography so far. Being an organic part of the “cultural revolution”, on the one hand, anti-religious films of this period acted as an effective tool for the propaganda of the Soviet state in the fight against both the official church and manifestations of everyday religiosity. On the other hand, their creation was accompanied by detailed theoretical and methodological recommendations on the forms of interaction of party propagandists with the audience, and on the formats for the presentation of anti-religious attitudes. Based on previously unpublished archival materials, the authors bring to the fore one of the most indicative of such films titled “Sectarians” shoot by Vladimir Korolevich (Sovkino, 1930). The authors consider the film as a document of that time and analyze processes that ran parallel with one another in the Soviet culture and policy. Taking the film “Sectarians” as a case-study, the authors explore cinematic methods of constructing a negative image of sectarian organizations in the USSR and its broadcast to a wide audience in ideological way. The authors came to the conclusion that the Soviet anti-religious cinema, combining the techniques of avant-garde cinematography and scientific atheism, successfully fulfilled its propaganda mission. In this context, the film “Sectarians” is a valuable historical source, that represented the contradictory phenomena of its time and was aimed at the visual reconstruction of “Sovietness” as a new religion. © 2021, Amur State University.

Molecular dynamics study of cluster structure and properties of rotational waves in solid nanostructures

The paper reports a molecular dynamics analysis of rotary properties of a transformational wave generated due to compressive influence. Studies are performed in the time interval prior to the onset of elastic precursor reflection from the free boundary. It is shown that the leading front of a rotary wave coincides with the transformational wave front. The rotary wave velocity for copper is determined, being equal to 1300 m/s. The values of angular moment projections onto the coordinate axes in a plane perpendicular to wave propagation are found to be symmetrical, and their total sum equals zero

“Russian Sakhalin” of Pyotr Polevoy: Visual and Anthropological Images

Поступила в редакцию: 25.05.2020. Принята к печати: 20.04.2021.Submitted: 25.05.2020. Accepted: 20.04.2021.Статья посвящена актуальной, но практически неисследованной в отечественной науке теме — визуальной антропологии как средству научного познания, конструирования и репрезентации образа территории. Определяющую роль в формировании образов фронтирных регионов страны в имперский и советский период играли профессиональные исследователи и путешественники. Предлагаемая работа открывает малоизвестную страницу в истории изучения Сахалина — творчество Петра Игнатьевича Полевого (1873–1938), одного из первопроходцев научного освоения острова. Основанная на архивных данных, многие из которых публикуются впервые, статья фокусируется на анализе визуально-антропологического наследия ученого, структурированного по основным направлениям его работ — антропология, геология и краеведение. Отражение в трудах исследователя посткаторжного периода в истории Сахалина, связанного с трансформацией колонизационной политики, дает особые сюжеты в плане изучения и позиционирования образа острова — форпоста страны в Азиатско-Тихоокеанском регионе. Путем сопоставления печатных и фотографических материалов выделяются и анализируются ключевые образы Сахалина в работах П. И. Полевого — «остров нефти», «остров инородцев» и «остров колонистов». Связанные между собой сквозной темой колонизации, они наглядно иллюстрируют положения исследователя о бесперспективности Сахалина как сельскохозяйственной колонии и рациональности его промышленного освоения. В теоретическом плане данная работа на конкретном примере развивает понятия из области визуальной антропологии («визуальная репрезентация региона», «этнографическая фотография») и культурной географии («образ региона», «культурный ландшафт»). Делается вывод о том, что наследие П. И. Полевого, включающее материалы междисциплинарного научного изучения Сахалина, в том числе его фотографические репрезентации, представляет собой информативный исторический источник для изучения динамичного образа дальневосточного фронтира в антропологии и смежных гуманитарных науках.This paper considers a relevant but practically unexplored topic, i.e. visual anthropology as a tool of scientific cognition as well as constructing and representing the image of a territory. Professional researchers and travellers contributed considerably to the formation of images of the frontier regions of Russia in the imperial and Soviet periods. This work opens a little-known page in the history of the study of Sakhalin — the work of Pyotr Ignatievich Polevoy (1873–1938), one of the pioneers in the scientific development of the island. Based on archival data, many of which are published for the first time, the article focuses on the analysis of the scientist’s visual and anthropological legacy and follows the main directions of his work — anthropology, geology, and local history. The reflection of the post-penal period in the history of Sakhalin related to the transformation of the colonisation policy, gives special ideas in terms of studying and representing the island’s image in the Asia-Pacific. The authors compare text and photographic materials and specify the key images of Sakhalin in the works of Polevoy, an “island of oil”, “island of foreigners” and “island of colonists”. Interconnected by the cross-cutting theme of colonisation, these images clearly illustrate the researcher’s position on the futility of Sakhalin as an agricultural colony and the rationality of its industrial development. The paper also develops concepts from visual anthropology (“visual representation of a region”, “ethnographic photography”) and cultural geography (“image of a region”, “cultural landscape”). The authors come to the conclusion that the legacy of Pyotr Polevoy (his scientific works and photographic representations) can be considered an informative historical source for studying the dynamic image of the Far Eastern frontier in anthropology and related humanities.Статья подготовлена за счет гранта РНФ № 19-18-00116 «Визуализация этничности: российские проекции науки, музея, кино» (рук.

Invariant variational principle for Hamiltonian mechanics

It is shown that the action for Hamiltonian equations of motion can be brought into invariant symplectic form. In other words, it can be formulated directly in terms of the symplectic structure $\omega$ without any need to choose some 1-form $\gamma$, such that $\omega= d \gamma$, which is not unique and does not even generally exist in a global sense.Comment: final version; to appear in J.Phys.A; 17 pages, 2 figure

Noether Symmetry Approach in "Cosmic Triad" Vector Field Scenario

To realize the accelerations in the early and late periods of our universe, we need to specify potentials for the dominant fields. In this paper, by using the Noether symmetry approach, we try to find suitable potentials in the "cosmic triad" vector field scenario. Because the equation of state parameter of dark energy has been constrained in the range of $-1.21\leq \omega\leq -0.89$ by observations, we derive the Noether conditions for the vector field in quintessence, phantom and quintom models, respectively. In the first two cases, constant potential solutions have been obtained. What is more, a fast decaying point-like solution with power-law potential is also found for the vector field in quintessence model. For the quintom case, we find an interesting constraint $\tilde{C}V_{p}'=-CV_{q}'$ on the field potentials, where $C$ and $\tilde{C}$ are constants related to the Noether symmetry.Comment: 15 pages, no figures, accepted by Classical and Quantum Gravity

ПРИНЦИПЫ ПОСТРОЕНИЯ БОРТОВОЙ СИСТЕМЫ РАННЕГО ПРЕДУПРЕЖДЕНИЯ ПИЛОТА О ВХОЖДЕНИИ В ВИХРЕВОЙ СЛЕД ОТ ДРУГОГО ВОЗДУШНОГО СУДНА

An airborne aircraft forms a wake vortex behind itself dangerous for other entering it aircraft both piloted and unmanned. Wake vortex intensity depends on parameters of the aircraft creating it, so the greater the aircraft mass is, the higher its impact on other aircraft is. It is not possible to register visually the wake vortex, since in fact it is invisible. Introduction of wide-body aircraft like A380 into service leads to the revision of separation rules with the aim to increase admissible distance between aircraft. There is a quite demonstrative case when Challenger 604 got into the wake vortex after A380: though separation rules at the altitude were observed, Challenger performed an out-of-control rotating descent from the altitude of 10000 m to 3000 m. At present, in spite of multi-year research there are no real verified suggestions on wake vortex safety of aircraft flights. The paper presents the methodological basis and design concepts of an onboard early warning system of a pilot about entering wake vortices from another aircraft. The main task of the proposed system is to reveal wake vortices according to pressure decrease in their cores; to do it we perform on-line measuring of pressure in front of an aircraft. Measurements are done by a standard onboard air data system and an onboard inertial satellite system in order to control the consistency of “barometric” altitude readings and those of altitude defined by an inertial satellite system. The value of wake vortices rarefaction measured by an onboard air data system allows estimating the influence degree of wake vortices on the aircraft roll moment with the help of a special hardware and software complex and to determine the necessity to change the flight mode. It is proposed to use a missile bench for the dimensioning wake vortices on aircraft models in order to test computational methods of wake vortices dimensioningПри движении в атмосфере за воздушным судном (ВС) формируется вихревой след, представляющий опасность для попадающих в него других ВС, как пилотируемых, так и беспилотных. Интенсивность вихревого следа зависит от характеристик создающего его ВС, причем чем больше масса ВС, тем больше возможное влияние его на другие ВС. Зафиксировать вихревой след визуально не представляется возможным, так как он невидим. Из-за появления в эксплуатации широкофюзеляжных самолетов типа А380 приходится пересматривать правила эшелонирования в сторону увеличения допустимого расстояния между ВС. Показательно в этом плане происшествие с попаданием ВС Challenger 604 в вихревой след от А380: правила эшелонирования были соблюдены, но тем не менее Challenger совершил неупорядоченное падение с высоты 10 км до 3 км. В настоящее время, несмотря на многолетние исследования, реальных верифицированных предложений по обеспечению вихревой безопасности полетов не имеется. В статье изложены методические основы и принципы построения бортовой системы раннего предупреждения о вхождении воздушного судна в вихревой след. Основой предлагаемой системы является обнаружение вихрей по понижению давления в их ядрах, для чего в режиме онлайн производится измерение давления перед самолетом. Измерения осуществляются штатной бортовой системой воздушных сигналов (БСВС) и бортовой инерциально-спутниковой системой для контроля согласованности в показаниях «барометрической» высоты полета и высоты полета, определенной инерциально-спутниковой системой. По величине измеренного БСВС разрежения в вихре специальным аппаратно-программным комплексом оценивается степень влияния вихревого следа на момент крена ВС и необходимость изменения режима полета. Для тестирования расчетных методов определения параметров вихревых следов предложено использовать ракетный трек по определению параметров вихревых следов на моделях воздушных судов
