description: The exchange of a pair of neutrinos with Standard Model weak interactions generates a long-range force between fermions. The associated potential is extremely feeble, $\propto G_F^2/r^5$ for massless neutrinos, whichrenders it far from observable even in the most sensitive experiments testing fifth forces. The presence of a neutrino background has been argued to induce a correction to the neutrino propagator that enhances the potential by orders of magnitude. In this brief note, we point out that such modified propagators are invalid if the background neutrino wavepackets have a finite width. By reevaluating the 2--$ν$ exchange potential in the presence of a neutrino background including finite width effects, we find that the background-induced enhancement is reduced by several orders of magnitude. Unfortunately, this pushes the resulting 2--$ν$ exchange potential away from present and near-future sensitivity of tests of new long-range forces.

description: Using the event-by-event viscous hydrodynamics VISH2+1 with MC-Glauber, MC-KLN, and AMPT initial conditions, we investigate the correlations of flow harmonics, including the symmetric cumulants $SC^{v}(m, n)$, the normalized symmetric cumulants $NSC(m, n)$, and the Pearson correlation coefficients $C(v_{m}^{2}, v_{n}^{2})$ in 2.76A TeV Pb--Pb collisions. We find $SC^{v}(m, n)$ is sensitive to both initial conditions and the specific shear viscosity $η/s$. A comparison with the recent ALICE data show that our hydrodynamic calculations can qualitatively describe the data of $SC^{v}(3, 2)$ and $SC^{v}(4, 2)$ for various initial conditions, which demonstrate that $v_2$, $v_4$ are correlated and $v_2$, $v_3$ are anti-correlated. Meanwhile, the predicted symmetric cumulants $SC^{v}(5, 2)$, $SC^{v}(5, 3)$, and $SC^{v}(4, 3)$ reveal that $v_2$ and $v_5$, $v_3$ and $v_5$ are correlated, $v_3$ and $v_4$ are anti-correlated in most centrality classes. We also find $NSC^{v}(3, 2)$ and $C(v_{3}^{2}, v_{2}^{2})$, which are insensitive to $η/s$, are mainly determined by corresponding $NSC^{\varepsilon}(3, 2)$ and $C(\varepsilon_{3}^{2}, \varepsilon_{2}^{2})$ correlators from the initial state. In contrast, other $NSC^{v}(m, n)$ and $C(v_{m}^{2}, v_{n}^{2})$ correlators are influenced by both initial conditions and $η/s$, which illustrates the non-linear mode couplings in higher flow harmonics with $n \geq 4$.

description: In axion-Maxwell theory at the minimal axion-photon coupling, we find non-invertible 0- and 1-form global symmetries arising from the naive shift and center symmetries. Since the Gauss law is anomalous, there is no conserved, gauge-invariant, and quantized electric charge. Rather, using half higher gauging, we find a non-invertible Gauss law associated with a non-invertible 1-form global symmetry, which is related to the Page charge. These symmetries act invertibly on the axion field and Wilson line, but non-invertibly on the monopoles and axion strings, leading to selection rules related to the Witten effect. We also derive various crossing relations between the defects. The non-invertible 0- and 1-form global symmetries mix with other invertible symmetries in a way reminiscent of a higher-group symmetry. Using this non-invertible higher symmetry structure, we derive universal inequalities on the energy scales where different infrared symmetries emerge in any renormalization group flow to the axion-Maxwell theory. Finally, we discuss implications for the Weak Gravity Conjecture and the Completeness Hypothesis in quantum gravity.

description: Understanding the interplay of order and disorder in chaotic systems is a central challenge in modern quantitative science. We present a universal, data-driven decomposition of chaos as an intermittently forced linear system. This work combines Takens' delay embedding with modern Koopman operator theory and sparse regression to obtain linear representations of strongly nonlinear dynamics. The result is a decomposition of chaotic dynamics into a linear model in the leading delay coordinates with forcing by low energy delay coordinates; we call this the Hankel alternative view of Koopman (HAVOK) analysis. This analysis is applied to the canonical Lorenz system, as well as to real-world examples such as the Earth's magnetic field reversal, and data from electrocardiogram, electroencephalogram, and measles outbreaks. In each case, the forcing statistics are non-Gaussian, with long tails corresponding to rare events that trigger intermittent switching and bursting phenomena; this forcing is highly predictive, providing a clear signature that precedes these events. Moreover, the activity of the forcing signal demarcates large coherent regions of phase space where the dynamics are approximately linear from those that are strongly nonlinear.

description: Text and pictures about the history of the IWW in Canada. The IWW (Industrial Workers of the World) was active in Canada from a very early point in the organization's history, especially in Western Canada, primarily in British Columbia. The union was active larely in organizing the lumber and mining industry along the coast, in the Interior of BC, and Vancouver Island. Some members of the IWW had relatively close links with the Socialist Party of Canada. Today the IWW remains active in Canada with branches active in Vancouver, Vancouver Island, Edmonton, Winnipeg, Ottawa, Toronto and Montr?al. Among the current IWW shops in Canada is the Ottawa Panhandlers' Union, which continues a tradition in the IWW of organizing disenfranchised workers on relief or in work camps started during the Great Depression. In the spirit of organizing industrially, any who make their living in the street, such as buskers, street vendors, or panhandlers are welcome to join the Ottawa Panhandlers' Union.

description: SU(5) $\otimes$ SU(5) provides a minimal grand unification scheme for fermions and gauge forces if there are vector-like quarks and leptons in nature. We explore the gauge coupling unification in a non-supersymmetric model of this type, and study its implications for proton decay. The properties of vector-like quarks and intermediate scales that emerge from coupling unification play a central role in suppressing proton decay. We find that in this model, the familiar decay mode $p \to e^+ π^0$ may have a partial lifetime within the reach of currently planned experiments.

description: Introduction: Vitamin D deficiency remains a global health issue, particularly in minority ethnic groups. There is a lack of research looking into the vitamin D status of the African-Caribbean population worldwide Objectives: This review investigates the vitamin D status (as measured by 25(OH)D or dietary intake) of the African-Caribbean population globally. Methods: A systematic review was conducted by searching key databases (PUBMED, Web of Science, Scopus) from inception until October 2019. Search terms included ‘Vitamin D status’ and ‘African-Caribbean’. A random effects and fixed effects meta-analysis was performed by combining means and standard error of the mean. Results: The search yielded 19 papers that included n=5,270 African-Caribbean participants from six countries. A meta-analysis model found this population to have sufficient (>50 nmol/L) 25(OH)D levels at 71.4nmol/L, 95% CI (62.8,80) and poor dietary intake of vitamin D at only 3.0µg/day, 95% CI (1.67,4.31). For those living at low latitudes ‘insufficient’ (defined by study authors) 25(OH)D levels were found only in participants with type 2 diabetes and those undergoing haemodialysis. Suboptimal dietary vitamin D intake was reported in all studies at high latitudes (UK recommended nutrient intake: 10µg/day). Studies at lower latitudes, with lower recommended dietary intakes (Caribbean recommended dietary intake: 2.5µg/day) found ’sufficient’ intake in two out of three studies. Conclusion: In African-Caribbean populations, 25(OH)D deficiency and low dietary vitamin D intake is more prevalent at higher latitudes.

description: В статье инструментами эстетико-философского анализа исследуются экзистенциальные аспекты феномена творчества. Креативность понимается как экзистенциал человеческого бытия, как фундаментальная характеристика и способность homo sapiens. Теоретическая модель homo faber, человека творящего, рассматривается как рядоположенная другим базовым измерениям человека экзистенциального – с экзистенциалами одиночества, любви, страха, опыта смерти и др. При этом подчеркивается особая значимость и специфичность акта творчества, который позволяет художнику и зрителю пережить момент вдохновения, творческого инсайта, испытать состояние охваченности замыслом. Историческая панорама философских и эстетико-художественных воззрений на проблему творчества, а также анализ произведений современного искусства приводят к пониманию креативности не только как основополагающего свойства человека как вида, но и как антропологической потребности.

description: Возникшие в стране после революции 1917 года театрализованные представления с аудиторией в десятки тысяч зрителей были знаковым явлением общественного и художественного быта. Искусство массовых театрализованных представлений вырывалось на улицы и площади, подчиняя исторические архитектурные ансамбли Петрограда художественному замыслу. Над этими постановками работали виднейшие деятели искусства начала XX века. Для анализа театрализованных представлений Петрограда в Государственном институте истории искусств был создан комитет социологического изучения искусств, специалисты которого занимались изучением массовых форм театрального искусства. В статье рассматривается методология исследования массовых зрелищ Гвоздева, анализируются критические и теоретические работы представителей гвоздевской школы, посвященные театрализованным представлениям Петрограда 1919–1920 годов.

description: Automatically describing the content of an image is a fundamental problem in artificial intelligence that connects computer vision and natural language processing. In this paper, we present a generative model based on a deep recurrent architecture that combines recent advances in computer vision and machine translation and that can be used to generate natural sentences describing an image. The model is trained to maximize the likelihood of the target description sentence given the training image. Experiments on several datasets show the accuracy of the model and the fluency of the language it learns solely from image descriptions. Our model is often quite accurate, which we verify both qualitatively and quantitatively. Finally, given the recent surge of interest in this task, a competition was organized in 2015 using the newly released COCO dataset. We describe and analyze the various improvements we applied to our own baseline and show the resulting performance in the competition, which we won ex-aequo with a team from Microsoft Research, and provide an open source implementation in TensorFlow.

description: Обращаясь к теме сада смерти не один раз, Хуго Симберг изображает смерть в виде добродушных скелетов, занятых поливом цветов в кадках, что весьма необычно. Также и сама трактовка сада лишь до некоторой степени перекликается с типологией campo santo, алхимическими и философскими садами, садами медитации и оскверненными садами. Не находя непосредственной преемственности Симбергом темы сада смерти в графике и живописи Г. Гольбейна Младшего, Д. Констебла, К. Кувассега и А. Бёклина, мы все же можем вписать его интерес к теме садов и образов смерти в контекст искусства рубежа XIX–XX веков, находя параллели в графике, поэзии и музыке того времени. В статье рассматривается широкий круг произведений европейских художников, а также популярные рисунки в периодике, по-разному трактующие тему смерти, мотивы скелета, сада, соотношения сакрального и профанного. Таким образом, наше исследование построено на использовании иконологии, иконографии и герменевтики.
Exact $\nabla^4 R^4$ couplings and helicity supertraces

description: In type II string theory compactified on a $d$-dimensional torus $T^d$ down to $D=10-d$ dimensions, the $R^4$ and $\nabla^4 R^4$ four-graviton couplings are known exactly, for all values of the moduli, in terms of certain Eisenstein series of the U-duality group $E_{d}(\mathbb{Z})$. In the limit where one circle in the torus becomes large, these couplings are expected to reduce to their counterpart in dimension $D+1$, plus threshold effects and exponentially suppressed corrections corresponding to BPS black holes in dimension $D+1$ whose worldline winds around the circle. By combining the weak coupling and large radius limits, we determine these exponentially suppressed corrections exactly, and demonstrate that the contributions of 1/4-BPS black holes to the $\nabla^4 R^4$ coupling are proportional to the appropriate helicity supertrace. Mathematically, our results provide the complete Fourier expansion of the next-to-minimal theta series of $E_{d+1}(\mathbb{Z})$ with respect to the maximal parabolic subgroup with Levi component $E_{d}$ for $d\leq 6$, and the complete Abelian part of the Fourier expansion of the same for $d=7$.

description: When considering a sequent-style proof system for quantum programs, there are certain elements of quantum mechanics that we may wish to capture, such as phase, dynamics of unitary transformations, and measurement probabilities. Traditional quantum logics which focus primarily on the abstract orthomodular lattice theory and structures of Hilbert spaces have not satisfactorily captured some of these elements. We can start from 'scratch' in an attempt to conceptually characterize the types of proof rules which should be in a system that represents elements necessary for quantum algorithms. This present work attempts to do this from the perspective of the quantum circuit model of quantum computation. A sequent calculus based on single quantum circuits is suggested, and its ability to incorporate important conceptual and dynamic aspects of quantum computing is discussed. In particular, preserving the representation of phase helps illustrate the role of interference as a resource in quantum computation. Interference also provides an intuitive basis for a non-monotonic calculus.

description: As the real-world impact of Artificial Intelligence (AI) systems has been steadily growing, so too have these systems come under increasing scrutiny. In response, the study of AI fairness has rapidly developed into a rich field of research with links to computer science, social science, law, and philosophy. Many technical solutions for measuring and achieving AI fairness have been proposed, yet their approach has been criticized in recent years for being misleading, unrealistic and harmful. In our paper, we survey these criticisms of AI fairness and identify key limitations that are inherent to the prototypical paradigm of AI fairness. By carefully outlining the extent to which technical solutions can realistically help in achieving AI fairness, we aim to provide the background necessary to form a nuanced opinion on developments in fair AI. This delineation also provides research opportunities for non-AI solutions peripheral to AI systems in supporting fair decision processes.

description: T CrB is a symbiotic recurrent nova known to exhibit active phases, characterised by apparent increases in the hot component temperature and the appearance of flickering, i.e. changes in the observed flux on the time-scale of minutes. Historical UV observations have ruled out orbital variability as an explanation for flickering and instead suggest flickering is caused by variable mass transfer. We have analysed optical and X-ray observations to investigate the nature of the flickering as well as the active phases in T CrB. The spectroscopic and photometric observations confirm that the active phases follow two periods of ~1000d and ~5000d. Flickering in the X-rays is detected and follows an amplitude-flux relationship similar to that observed in the optical. The flickering is most prominent at harder X-ray energies, suggesting that it originates in the boundary layer between the accretion disc and the white dwarf. The X-ray radiation from the boundary layer is then reprocessed by a thick accretion disc or a nebula into UV radiation. A more detailed understanding of flickering would benefit from long-term simultaneous X-ray and optical monitoring of the phenomena in symbiotic recurrent novae and related systems such as Z And type symbiotic stars.

description: It has been hypothesized that liquid polyamorphism, the existence of multiple amorphous states in a single component substance, may be caused by molecular or supramolecular interconversion. A simple microscopic model [Caupin and Anisimov, Phys. Rev. Lett., 127, 185701, (2021)] introduces interconversion in a compressible binary lattice to generate various thermodynamic scenarios for fluids that exhibit liquid polyamorphism and/or water-like anomalies. Using this model, we demonstrate the dramatic effects of interconversion on the interfacial properties. In particular, we find that the liquid-vapor surface tension exhibits either an inflection point or two extrema in its temperature dependence. Correspondingly, we observe anomalous behavior of the interfacial thickness and a significant shift in the location of the concentration profile with respect to the location of the density profile.

description: В статье рассматриваются идейно-художественные взаимосвязи немецкого искусства 1920-х годов с итальянской метафизической живописью. Автор подробно разбирает тексты и манифесты итальянских и немецких художников, выявляя общие теоретические воззрения на искусство обеих сторон. В центре внимания автора – образ «нового человека» в немецком искусстве, который, зародившись в контексте экспрессионизма, получил в 1920-е годы иное выражение и значение. При помощи стилистических принципов pittura metafisica, а также ее главного персонажа – манекена – немецкие художники создали собственную версию «нового человека». Берлинские дадаисты и представители новой вещественности оставляют за рамками метафизический смысл, изначально заложенный в манекенах К. Карра и Дж. де Кирико, и помещают «нового человека» в современные им социально-политические реалии Веймарской Германии, создавая таким образом злободневное искусство.

В этих условиях в Лондоне крупные издательства, ежегодно выпускавшие роскошные подарочные книги под Рождество, стремясь подстроиться под массовый ажиотаж вокруг искусства Востока, стали приглашать молодых и перспективных графиков иллюстрировать данные издания. В числе таких художников, активно сотрудничавших с подобными издательствами, был и выдающийся франко-английский иллюстратор Эдмунд Дюлак (1882–1953). Статья раскрывает одну из ключевых сторон деятельности данного иллюстратора. На основе материалов творчества Дюлака рассматриваются попытки художника передать тематическое и стилистическое своеобразие искусства Востока в контексте актуальной для него среды мастеров книжной иллюстрации эдвардианской эпохи и второго десятилетия XX века.

description: Brain function results from communication between neurons connected by complex synaptic networks. Synapses are themselves highly complex and diverse signaling machines, containing protein products of hundreds of different genes, some in hundreds of copies, arranged in precise lattice at each individual synapse. Synapses are fundamental not only to synaptic network function but also to network development, adaptation, and memory. In addition, abnormalities of synapse numbers or molecular components are implicated in most mental and neurological disorders. Despite their obvious importance, mammalian synapse populations have so far resisted detailed quantitative study. In human brains and most animal nervous systems, synapses are very small and very densely packed: there are approximately 1 billion synapses per cubic millimeter of human cortex. This volumetric density poses very substantial challenges to proteometric analysis at the critical level of the individual synapse. The present work describes new probabilistic image analysis methods for single-synapse analysis of synapse populations in both animal and human brains.

description: The increasingly widespread adoption of large language models has highlighted the need for improving their explainability. We present context length probing, a novel explanation technique for causal language models, based on tracking the predictions of a model as a function of the length of available context, and allowing to assign differential importance scores to different contexts. The technique is model-agnostic and does not rely on access to model internals beyond computing token-level probabilities. We apply context length probing to large pre-trained language models and offer some initial analyses and insights, including the potential for studying long-range dependencies. The source code and an interactive demo of the method are available.

description: For an algebraic number $α$ of degree $n$, let $\mathcal{M}_α$ be the $\mathbb{Z}$-module generated by $1,α,\ldots ,α^{n-1}$; then $\mathbb{Z}_α:=\{ξ\in\mathbb{Q} (α):\, ξ\mathcal{M}_α\subseteq\mathcal{M}_α\}$ is the ring of scalars of $\mathcal{M}_α$. We call an order of the shape $\mathbb{Z}_α$ \emph{rationally monogenic}. If $α$ is an algebraic integer, then $\mathbb{Z}_α=\mathbb{Z}[α]$ is monogenic. Rationally monogenic orders are special types of invariant orders of binary forms, which have been studied intensively. If $α,β$ are two $\text{GL}_2(\mathbb{Z})$-equivalent algebraic numbers, i.e., $β=(aα+b)/(cα+d)$ for some $\big(\begin{smallmatrix}a&b\\c&d\end{smallmatrix}\big)\in\text{GL}_2(\mathbb{Z})$, then $\mathbb{Z}_α=\mathbb{Z}_β$. Given an order $\mathcal{O}$ of a number field, we call a $\text{GL}_2(\mathbb{Z})$-equivalence class of $α$ with $\mathbb{Z}_α=\mathcal{O}$ a \emph{rational monogenization} of $\mathcal{O}$. We prove the following. If $K$ is a quartic number field, then $K$ has only finitely many orders with more than two rational monogenizations. This is best possible. Further, if $K$ is a number field of degree $\geq 5$, the Galois group of whose normal closure is $5$-transitive, then $K$ has only finitely many orders with more than one rational monogenization. The proof uses finiteness results for unit equations, which in turn were derived from Schmidt's Subspace Theorem. We generalize the above results to rationally monogenic orders over rings of $S$-integers of number fields. Our results extend work of Bérczes, Győry and the author from 2013 on multiply monogenic orders.

description: In this work, we study the propagation and absorption of plasma waves in the chiral Maxwell-Carroll-Field-Jackiw (MCJF) electrodynamics. The Maxwell equations are rewritten for a cold, uniform, and collisionless fluid plasma model, allowing us to determine the new refractive indices and propagating modes. The cases of propagation parallel and orthogonal to the magnetic field are examined considering a purely timelike CFJ background that plays the role of the magnetic conductivity chiral parameter. The collective electromagnetic modes are associated with four distinct refractive indices associated with right-circularly polarized and left-circularly polarized waves. For each index, the propagation and absorption zones are illustrated for some specific parameter values. In low-frequency regime, we have obtained modified helicons with right- and left-circularly polarizations. The optical behavior is investigated by means of the rotatory power (RP) and dichroism coefficient. The existence of a negative refraction zone enhances the rotatory power. It is also observed RP sign reversal, a feature of rotating plasmas.

description: Quantum dynamics and kinetics of electrically gated graphene ribbons with lateral n-p and e-n-p junctions under magnetic field are investigated. It is shown that the snake-like states of quasiparticles skipping along the n-p interface do not manifest themselve in the main semiclassical part of the ribbon conductance. Giant oscillations of the conductance of a ribbon with an n-p-n junction are predicted and analytically calculated. Depending on the number of junctions inside the ribbon its magnetoresistance may be controllably changed by 50% - 90% by an extremely small change of the magnetic field or the gate voltage.

An Overview of Approaches to Modernize Quantum Annealing Using Local Searches

description: I describe how real quantum annealers may be used to perform local (in state space) searches around specified states, rather than the global searches traditionally implemented in the quantum annealing algorithm. The quantum annealing algorithm is an analogue of simulated annealing, a classical numerical technique which is now obsolete. Hence, I explore strategies to use an annealer in a way which takes advantage of modern classical optimization algorithms, and additionally should be less sensitive to problem mis-specification then the traditional quantum annealing algorithm.
description: In Proceedings PC 2016, arXiv:1606.06513. An extended version of this contribution will appear on arXiv soon which will describe more detailed algorithms, comment more on robustness to problem mis-specification, comment on thermal sampling applications, and discuss applications on real devices
Искусство США в свете эволюции морали и запрета на сакральное

description: В фокусе внимания статьи находится проблема запретов, существующих в культуре США от самого ее зарождения в XVII столетии вплоть до наших дней, и то модифицирующее воздействие, которое они оказали на сложение языка американского изобразительного искусства, его национальную специфику. Одно из наиболее влиятельных среди таких ограничений – табу на репрезентацию сакрального – вместе с отрицанием обнаженной натуры лишило Америку значительной части изобразительности, конститутивной для западной художественной традиции. Результатом действия этих запретов и реакцией на их существование стал ряд последовательно рассматриваемых в статье работ (от Густавуса Хесселиуса в начале XVIII века до Томаса Икинса на рубеже XIX–XX столетий), делавших попытку даже в таких условиях все же изобразить божественное. Самая яркая и репрезентативная среди них – объект «Бог» (1917), долгое время приписывавшийся Мортону Шамбергу, а теперь закрепленный за одной из ярчайших фигур авангарда баронессой Эльзой фон Фрайтаг-Лорингхофен. Этот реди-мейд, созданный в момент начала активной интеграции искусства США в модернистский художественный процесс, венчает собой американскую традицию изображения (или, скорее, не-изображения) сакрального. Пережив наряду с «Фонтаном» Дюшана переоценку авторства, сегодня этот знаменательный художественный объект нуждается в новой экспертизе его содержания, сделать которую невозможно без понимания описанной выше истории самоцензуры американского искусства.
Positivity-preserving entropy filtering for the ideal magnetohydrodynamics equations

description: In this work, we present a positivity-preserving adaptive filtering approach for discontinuous spectral element approximations of the ideal magnetohydrodynamics equations. This approach combines the entropy filtering method (Dzanic and Witherden, J. Comput. Phys., 468, 2022) for shock capturing in gas dynamics along with the eight-wave method for enforcing a divergence-free magnetic field. Due to the inclusion of non-conservative source terms, an operator-splitting approach is introduced to ensure that the positivity and entropy constraints remain satisfied by the discrete solution. Furthermore, a computationally efficient algorithm for solving the optimization process for this nonlinear filtering approach is presented. The resulting scheme can robustly resolve strong discontinuities on general unstructured grids without tunable parameters while recovering high-order accuracy for smooth solutions. The efficacy of the scheme is shown in numerical experiments on various problems including extremely magnetized blast waves and three-dimensional magnetohydrodynamic instabilities.

Репрезентативные стратегии видеоинсталляции

Subjects: инсталляция

description: Статья посвящена одному из типов художественной инсталляции – видеоинсталляции. Ее зарождение стало возможным после трансформации видео в один из ведущих медиумов произведений современного искусства. Это случилось благодаря появлению на рынке портативных видеокамер. Существуют споры относительно принадлежности видеоинсталляции к видеоарту и художественной инсталляции, а также точка зрения автора на этот вопрос. Отмечается, что на формирование данного типа инсталляции оказали большое влияние идеи М. Маклюэна о «холодных» и «горячих» медиа. Основной акцент в работе также делается на разнообразие творческих стратегий репрезентации видеоинсталляции. Для этого используется метод сравнительного анализа данного типа инсталляции с прочими практиками. Такой подход позволяет обратить внимание на скульптуроподобность образных элементов, использование эстетики «тромплей», взаимодействие инсталляционных произведений искусства со зрителем, а также использование времени как художественного медиума при создании работы. В качестве примеров рассматриваются работы зарубежных и российских художников, которые, по мнению автора, наиболее точно демонстрируют вышеуказанные творческие стратегии.

description: Статья посвящена самым первым образам цивилизации и города в игровом кино – в фантастических фильмах Жоржа Мельеса. Рассматриваются особенности видения «островов» цивилизации посреди каменистого ландшафта и активного траффика летательных аппаратов, что позже будет взято на вооружение научно-фантастическим кинематографом. Пространство космоса у Мельеса довольно густо заселено, образуя своего рода космическую «агломерацию». В своих фильмах-путешествиях режиссер активно моделирует образ цивилизации не столько через пространственную среду, сколько через симбиоз отсылок к миру науки, зрелищно-игровой городской культуры и поведенческих кодов персонажей, для которых весьма важны медийные аспекты их деятельности. Рефлексируя о прогрессе цивилизации в фильме «Легенда о Рип ван Винкле», режиссер создает образ декоративной, живописной деревни, словно созданной для досуга горожан, то есть косвенно отображающей процессы урбанизации. В «Автотурне Париж – Монте Карло…» возникают образы столичной богемной среды и эскиз курортной зоны. В целом у Мельеса формируется концепция экранной трюковой деструкции цивилизационной / городской среды, что выполняет компенсаторную функцию в современном обществе, негативно относящемся к разрушительным процессам в реальной обыденности.
Визуализация в кино сеттинга поздних пьес Чехова. Образ Треплева у Сидни Люмета

description: В статье рассматривается экранизация Сидни Люмета пьесы Антона Чехова «Чайка». В основе анализа – сопоставление сеттинга драматического произведения и его воплощения на киноэкране. Анализ строится на сравнении социально-исторических реалий Российской империи конца XIX – начала XX века и их визуализаций в указанном фильме. Этот спектр очень широк: от условий исключения студентов из университета – до тонкостей наследственного права. Фильм Люмета выбран для анализа по нескольким причинам. Во-первых, по общему мнению, это одна из лучших экранизаций «Чайки», во-вторых, эта картина свободна от многих идеологических наслоений, влияющих на восприятие творчества Чехова, в-третьих, это работа состоявшегося режиссера – интересного как зрителям, так и исследователям. В статье приводятся несколько примеров, подтверждающих тот тезис, что социально-исторические реалии России конца XIX – начала XX века визуализируются Сидни Люметом в несколько искаженном виде. Это приводит к не вполне адекватному взгляду на систему образов, выстроенную Чеховым, и в конечном итоге на всю пьесу. Анализ позволяет продемонстрировать работу чеховского текста на разных уровнях восприятия. Неподготовленный постановщик видит в них зазубренную еще в начальных учебных заведениях версию о серой и скучной бесконфликтной жизни России того времени. Читатель или режиссер, знакомый с бытом указанного периода, увидит совершенно других героев, связанных иной, более интересной и глубокой сетью межличностных отношений. Эта демонстрация позволяет сделать ряд новых выводов об эстетике пьесы Чехова.
