«Vision of John the Terrible» by S.M. Slonimskiy: intertextual aspects of the opera
Authors: Лазанчина А.В.
Published: September 2024

Опера С.М. Слонимского Видения Иоанна Грозного рассматривается в статье как одно из значительных явлений в области отечественного музыкального театра конца ХХ века. Анализ произведения осуществляется с позиций интертекстуальности. На оперу оказали влияние произведения разных видов искусства: музыки и литературы, живописи и скульптуры, кино и театра. Своеобразие драматургии оперы определяется ориентацией на средневековый литературный жанр видений. Цель статьи выделить музыкальные межтекстовые связи сочинения Слонимского с произведениями М.П. Мусоргского, А.П. Бородина, Н.А. РимскогоКорсакова, Д.Д. Шостаковича. Влияния оперной классики на современное произведение прослеживаются на образнодраматургическом, структурнокомпозиционном и интонационном уровнях. Постановка оперы на сцене Самарского академического театра оперы и балета подчеркивает многоплановость сочинения. Интертекстуальный подход к изучению оперы позволяет выявить позицию композитора к проблеме наследия. В этом отношении С.М. Слонимский является несомненным продолжателем лучших традиций русской оперной классики, сумевшим создать на ее основе свой собственный индивидуальный стиль.

Opera Visions of John the Terrible by S.M. Slonimskiy is considered in the article as one of the significant phenomena in the field of Russian musical theater of the late twentieth century. Analysis of the work is carried out from the standpoint of intertextuality. The opera was influenced by works of various types of art: music and literature, painting and sculpture, cinema and theater. The peculiarity of the dramaturgy of the opera is determined by its orientation towards the medieval literary genre of visions. The article focuses on the identification of musical intertextual relations of the opera with the works of M.P. Musorgsky, A.P. Borodin, N.A. RimskyKorsakov, D.D. Shostakovich. The infl uences of opera classics on a contemporary work can be traced at figuratively dramatic, structural, compositional and intonational levels. The staging of the opera on the stage of the Samara Academic Opera and Ballet Theater emphasized the versatility of the composition. The intertextual approach to the study of opera reveals the composers position on the problem of heritage. In this regard, S.M. Slonimsky is an undoubted successor of the best traditions of Russian opera classics, on the basis of which he managed to create his own authors style.

Polydialective specificity of language as the basis of Crimean Tatar song intonation
Authors: Алимова Э.С.
Published: September 2024

При знакомстве с любой национальной школой, прежде всего, следует обратить внимание на её фольклорные истоки, так как они являются основополагающими для певческого стиля. В первую очередь внимание привлекает фонетика, которая в каждом языке отличается собственной спецификой. Так гласные имеют свойство редуцироваться, а некоторые согласные в диалектах разных народов либо используются крайне редко, либо произносятся с определённым характером. Считается, что полидиалектность крымскотатарского языка сохранилась до наших дней. Несмотря на смешение наречий, выделяют два базовых диалекта тюркский и заимствованный (в его состав входят элементы арабских, персидских и греческих языков). Что касается техники пения, то она во многом зависела от музыкального жанра, характера произведения и фонетики. Последняя, с учётом языковых особенностей, конфликтовала с методикой обучения академического вокала. При профессиональной певческой фонации, как правило, не акцентируется внимание на специфике национального произношения, а берутся за основу общепринятые нормы и правила. Однако именно народное исполнительство играет ведущую роль в музыке крымскотатарских народов, что позволяет ей оставаться яркой, самобытной и стилистически единой.

When familiar with any national school, attention should first be paid to its folklore origins, as they are the founders of the singing style. First of all, attention is drawn to phonetics, which in each language has its own specificity. So vowels have the property of being reduced, and some consonants in dialects of different peoples either appear extremely rarely or are pronounced with a certain character. It is believed that the polydialicity of the Crimean Tatars language has survived to the present day. Despite the mixing of adverbs, two basic dialects are identified Turkic and borrowed (it includes features of Arabic, Persian and Greek languages). As for the technique of singing, it was largely dependent on the musical genre, the nature of the work and phonetics. The latter, taking into account language features, clashed with the methodology of teaching academic vocals. Professional singing phonation generally does not focus on the specifics of national pronunciation, but takes as a basis generally accepted norms and rules. However, it is folk performance that plays a leading role in the music of Crimean Tatar peoples, which allows it to remain bright, original and stylistically united.

Language features of Chinese dialects and their influence on the process of mastering the European singing school
Authors: Шалаева А.А.
Published: September 2024

Цель статьи ознакомиться с наиболее распространёнными диалектами китайского языка, представляющими трудности при обучении славянской, германской и романской группы индоевропейского языка в академическом пении. После культурной китайской революции (1966 1976) влияние западноевропейских вокальных школ оказало существенное влияние на возникновение и развитие классического пения на территории Китая. Однако, изза расширения межкультурных коммуникаций в области академического пения, появились некоторые фонетические трудности в понимании и овладении классического репертуара. Знание основных диалектов китайского языка, с которыми сталкивались практически все вокальные педагоги, призвано помочь ускорить процесс адаптации китайских певцов к европейскому исполнительству. Китайский язык является наиболее распространённым современным языком с общим числом говорящих более 1,3 млрд. человек. Он подразделяется на несколько диалектных групп. Условно автор выделяет 2 большие группы диалектов: северный и южный, которые между собой различны. Проведен анализ фонетического акцента носителей южных диалектов в сопоставлении с фонетическим акцентом носителей северных диалектов, поскольку южный диалект значительно отличается от других диалектов: около 90 слов произносится говорящими на этом диалекте поиному. Автор делает вывод, что при работе с китайскими студентамивокалистами педагогу нужно учитывать наличие диалектов как факт языковой ситуации в Китае.

The purpose of the article is to get acquainted with the most common dialects of the Chinese language, representing difficulties in teaching Slavic, Germanic and romance groups of the IndoEuropean language in academic singing. After the Chinese cultural revolution (1966 1976), the influence of Western European vocal schools had a significant impact on the emergence and development of classical singing in China. However, due to the expansion of intercultural communication in the field of academic singing, there were some phonetic difficulties in understanding and mastering the classical repertoire. Knowledge of the basic dialects of Chinese, which almost all vocal teachers have encountered, is designed to help speed up the process of adaptation of Chinese singers to European performance. Chinese is the most common modern language with a total of more than 1.3 speakers. It is subdivided into several dialect groups. Conventionally, the author identifies 2 large groups of dialects: northern and southern, which are different from each other. The analysis of the phonetic accent of southern dialect speakers in comparison with the phonetic accent of Northern dialect speakers is carried out, since the southern dialect differs significantly from other dialects: about 90 of words are pronounced by speakers of this dialect in a different way. The author concludes that when working with Chinese vocal students, the teacher should take into account the presence of dialects as a fact of the language situation in China.

В работе рассматриваются особенности построения сверхминиатюрных электроакустических аппаратов индивидуального пользования. Отмечается, что надежность работы миниатюрных аппаратов определяется уже не надежностью схемного решения, то есть электронного усилителя, преобразователей и т.д., а конструкцией миниатюрных и сверхминиатюрных органов и элементов управления. Настройка эксплуатационных характеристик и параметров современных миниатюрных электроакустических аппаратов должна осуществляться в специальных лабораториях с учетом индивидуальных свойств слуховой системы каждого потребителя слуховых аппаратов. Авторы данной работы предлагают схему усилителя для миниатюрной электроакустической системы, имеющего пять программно управляемых (регулируемых) основных параметров.

The paper deals with the construction features of subminiature electroacoustic devices for individual use. It is noted that the reliability of the miniature devices is no longer determined by the reliability of the circuit solution, i.e. an electronic amplifier, converters, etc., but by the design of miniature and superminiature control element. Setting the characteristics and parameters of modern miniature electroacoustic devices should be carried out in special laboratories, taking into account the individual specificity of each hearing aid consumers auditory system. The authors of this paper propose an amplifier circuit for a miniature electroacoustic system with five softwarecontrolled (adjustable) basic parameters.

Published: September 2024

Новые знания относительно характеристической функции случайных процессов позволяют в приборостроении скачком улучшить характеристики разных устройств. В работе рассматриваются модем и фильтр. На примере помехоустойчивости теоретически обосновано возможное повышение на несколько порядков этой характеристики у модемов нового поколения, описание и структура которых опубликована в современной литературе за последний год. Нижеследующие результаты теоретических исследований в направлении динамического хаоса по закону арксинуса касаются структуры из модема и фильтра, работающего в пространстве вероятностей. Такая структура теоретически позволяет обеспечить работу цифровых систем связи с амплитудной манипуляцией при сигналах на 22 дБ меньше шума. При этом помехоустойчивость цифровых систем сохраняется высокая, а вероятность ошибок имеет значение 10 20 и менее. Модем с виртуальным фильтром разрабатывается для цифровых систем, необходимых в будущем для внедрения цифровых технологий.

New knowledge of the characteristic function of random processes makes it possible to improve the characteristics of different devices in instrument making. The work deals with modem and filter. On the example of noise immunity, the possible increase by several orders of magnitude of this characteristic in modems of the new generation, the description and structure of which have been published in modern literature over the last year, is theoretically justified. The following results of theoretical studies in the direction of dynamic chaos according to arcsine law concern a structure from a modem and a filter operating in probability space. Such a structure theoretically allows the operation of digital communication systems with amplitude manipulation at signals 22 dB less noise. At the same time noise immunity of digital systems is maintained high, and probability of errors has value and less. A virtual filter modem is being developed for digital systems needed in the future to implement digital technologies.

THE PRUSSIAN LANDOWNERS OF NATTANGIA UNDER THE RULE OF THE TEUTONIC ORDER IN 1249–1370
Authors: Денисов С.А.
Published: September 2024

Статья посвящена инкорпорированию пруссов в социальную систему Орденского государства в 1249 1370 гг. Данный вопрос рассмотрен на основе источников (актов и хроник), освещающих историю Наттангии, одной из 11 прусских племенных земель, где политика братьев по привлечению пруссов на свою сторону была наиболее эффективной. Принципы инкорпорирования наттангов в Орденское государство, отдельно не рассмотренные в историографии, были исследованы при помощи сравнительноисторического, типологического и просопографического методов. В результате были выявлены две группы ленников, обязанных после пожалования земельного надела нести службу (группа 1) и дополнительно платить налог (группа 2). Внутри обеих групп происходил процесс социальноимущественной дифференциации (аккумуляция имущества, отказ от использования надела), регулируемый Орденом при помощи ряда мер: пожалование участка группе лиц, штраф за ущерб здоровью землевладельца (вергельд), подтверждение права на ранее выданные участки. Данные меры, позволившие стабилизировать землепользование в Наттангии, говорят о стремлении Ордена не только получить в лице прусских ленников военную силу, но также максимально использовать за счет них земельный фонд. Активное привлечение наттангов к походам в качестве военной силы было обусловлено их успешным включением в состав орденского войска как легкой конницы, что отвечало их традиционным тактике и вооружению.

The article is devoted to the involvement of Prussians in the social system of Orders State in 1249 1370. This process was studied on the basis of sources (acts and chronicles), which bring light to the history of Nattangia, one of the 11 tribal lands of Prussia, where Orders policies to attract Prussians was the most effective. Principles of Nattangians involvement, which were not studied in historiography, were researched by using of historicalcomparative, typological and prosopographical methods. As a result there were determined two groups of lieges, who were obliged to hold military service for the grants of land property (group 1) and additionally to pay tax (group 2). Among representatives of both groups there was the process of socialproperty differentiation (accumulation of property, refuse of the estates cultivation), which was regulated by the Order with special measures: grants of estate to the group of holders (often relatives), the introduction of penalty for the damage to the health of holder (vergeld), confirmation of the rights on the early granted estates. These measures, which allowed to flatten cultivation of land, testify that Order sought not only to obtain military force from Prussian lieges, but also to use with their help its own land fund. Active attraction of Nattangians to the campaigns as military force was caused by their successful invitation in Orders army as light cavalry that met traditional tactic and equipment of Prussians.

Published: September 2024

Regioselective γ-polyhaloalkylation is achieved using tetrahalomethanes or α,α,α-trihaloalkyl compounds and siloxydienes via Fe(II) catalysis. A range of siloxydienes are functionalized in good yield and high stereoselectivity under mild reaction conditions. Structural divergence is observed as either haloalkylated or haloalkenylated products are formed based on substitution pattern of the siloxydiene. The halogenated products show utility in further synthetic transformations selec- tive reduction and cross coupling reactions.
Long Molecular Wires and the Auto-ionization of Water

Published: September 2024

Water auto-ionization is critical in a wide range of chemical, biological, physical, and industrial processes. In this work, we describe a series of hitherto unknown collective molecular processes leading to auto-ionization. Specifically, by combining machine-learned interatomic potentials and spectral adaptive biasing force techniques, we determine the relevant free energy landscape of water auto-ionization. At ambient conditions, the free energy profile reveals two distinct saddle points, each leading to the formation of three- and four-member water wires. The wires feature an individual Zundel ion and a proton diffusion-like transition state, respectively. At elevated temperatures, the auto-ionization process exhibits a more concerted hydrogen transfer mechanism and reveals an alternative pathway involving the synchronous diffusion of Zundel ion pairs, with the ion pair corresponding to an energetic local minimum on the free energy surface. These findings help resolve long-standing conflicting views of the mechanism of water auto-ionization and provide new avenues for the study of proton behavior in different aqueous environments.

A novel molecular structure that merges the fields of molecular optical cycling with molecular photoswitching is presented. It is based on a photoswitching molecule azobenzene functionalized with one and two CaO- groups, which can act as optical cycling centers (OCCs). This paper characterizes the electronic structure of the resulting model systems, focusing on three questions: (1) how the electronic states of the photoswitch are impacted by a functionalization with an OCC; (2) how the states of the OCC are impacted by the scaffold of the photoswitch; (3) whether the OCC can serve as spectroscopic probe of isomerization. The experimental feasibility of the proposed design and the advantages that organic synthesis can offer in fur- ther functionalization of the molecular scaffold are also discussed. This work brings into the field of molecular optical cycling a new dimension of chemical complexity, intrinsic only to polyatomic molecules.
A Motif for Generating Coherently Degenerate States in A-D-D-A Type Organic Small Molecules
Authors: Zhuang Junpeng , Wang Lichang
Published: September 2024

Encouraged by the superior performance of the D-A-A-D dimer in generating Wannier excitons, we developed a new motif to construct A-D-D-A type organic small molecules. The donor moieties consist of 4,4’-dimethyl-4”-((4-amino)styryl)-triphenylamine, while the acceptor is an s-triazine derivative. DFT studies, using two detection techniques, confirmed that a pair of Wannier exictons is generated in one of the newly designed compounds studied here. Based on the analysis of molecular orbitals and the UV-Vis spectrum, A-D-D-A-2 has been identified as the Wannier molecule. Although A-D-D-A-1 is not confirmed as a Wannier molecule based on the molecular orbital inspection, it may still generate Wannier excitons; however further studies with new techniques are needed to confirm this. A brief discussion of the double excitation in A-D-D-A-2 is also provided. The motif used in the formation of Wannier molecules of A-D-D-A type dimers, i.e. A-D-D-A-2, is the same motif as in the other high performing organic small molecules. This suggests that these high-performance organic molecules may already generate Wannier excitons, which could be the primary reason for their exceptional performance as photosensitizers in solar cells.
Metal-Organic Frameworks for the Trace Multiplexed Quantitation of 50 PFAS by Liquid Chromatography Mass Spectrometry
Authors: Hua Lisa , Solomon Marcello , D'Alessandro Deanna , Donald William
Published: September 2024

Per- and polyfluoroalkyl substances (PFAS) are environmental contaminants of increasing concern due to their persistence and potential health impacts. New guidelines with exceedingly low detection limits necessitate the development of promising materials for preconcentration. Six different metal-organic frameworks were evaluated for their potential as dispersive solid-phase extraction (dSPE) sorbents for PFAS quantitation by quantitative liquid chromatography tandem mass spectrometry (LC-MS/MS). UiO-66 demonstrated the highest combined average adsorption (87%) and recovery (85%) across 33 PFAS spiked in water at 2 ppb, and 75% recovery for 50 PFAS at 200 ppq. The developed dSPE workflow using UiO-66 resulted in limit of detections (LODs) as low as 4 ppq with average LODs of 108 ppq across 50 PFAS by testing at concentrations of 200 to 800 ppq. UiO-66 retained its crystalline structure post-PFAS adsorption, indicating stability for dSPE. Nearly 100% average recovery across all 50 PFAS was observed for UiO-66 using a 20 ppt spike, whereas ZIF-8 resulted in lower recovery. The efficacy of using UiO-66 as a dSPE material was assessed using six environmental water samples from different locations in Sydney, Australia, with all samples having quantifiable levels of PFAS. In water collected from Sydney Airport, 22 PFAS were detected above the limit of quantification (LOQ). Across all environmental water samples, a total of 25 PFAS were quantified above LOQs, with internal standard recoveries between 70-120%. In addition, the presence of multiply charged counterions decreased short-chained PFAS adsorption, while chloride had no impact. While polymeric resins have been used for screening ~50 PFAS with limits of detection ranging from 1 to 80 ppt, UiO-66 can be used to detect 50 PFAS at concentrations as low as 200 ppq. The high performance of UiO-66 in terms of recovery and detection limits underscores its potential for practical analytical applications in PFAS detection.
A Deep Learning-based Approach for Channel Estimation in Multi-access Multi-antenna Systems
Authors: Qasaymeh Mahmoud , Alqatawneh Ali , Khodeir Mahmoud A. , Aljaafreh Ahmad
Published: September 2024

This paper studies estimating the channel state information at the end of receiver (CSIR) for multiple transmitters communicating with only one receiver so that the latter can decode the incoming signal more efficiently. The transmitters and the receiver are all equipped with multi-antennas and using orthogonal space-time block codes (OSTBC). An algorithm is developed based on deep learning for estimating multi-user multiple-input multiple-output (MU-MIMO) channels. The algorithm could estimate the CSIR using a single pilot block. The proposed convolutional neural network (CNN) architecture designed for this task begins with an input layer that accepts grayscale images, followed by six convolutional blocks for feature extraction and processing. The network concludes with a fully connected layer to output the estimated channel information. It is trained using a regression loss function to map input images to accurate channel information accurately. The performance of the proposed method is compared with classical methods like least square and subspace-based methods, including Capon and rank revealing QR (RRQR) methods. CNN achieved better performance in comparison with the reference. Computer simulations are included to validate the proposed method.
“ELA É MINHA AMIGA!”: INTERAÇÃO E SOCIABILIDADE ENTRE CRIANÇAS HAITIANAS E BRASILEIRAS NA EDUCAÇÃO INFANTIL
Authors: Da Silva Machado Rosana , De Cássia Marchi Rita
Published: September 2024

Sendo a migração infantil um fenômeno crescente na atualidade, é necessário refletir sobre a inserção de crianças migrantes em instituições educacionais, como forma de garantir seus direitos. O objetivo deste artigo é discutir a interação e sociabilidade entre crianças brasileiras e haitianas (3 a 6 anos) em Núcleos de Educação Infantil (NEIs). A pesquisa, qualitativa, fez uso de técnicas da etnografia (notadamente a observação participante) para a geração de dados junto a crianças haitianas e brasileiras, adultos haitianos, e docentes de dois NEIs do Município de Balneário Camboriú (SC). Os dados também foram gerados através de conversas com crianças e adultos, e por meio de um livro de história sobre a migração haitiana, de autoria da pesquisadora (com a participação das crianças como ilustradoras). As observações foram registradas em diário de campo e foram realizados registros fotográficos do cotidiano escolar. A investigação foi fundamentada nos Estudos Sociais da Infância, que reconhecem a criança como ator social de pleno direito e produtora de cultura, e nos estudos das relações étnico-raciais, que evidenciam as desigualdades entre crianças pertencentes a diferentes grupos étnicos raciais. Diferentemente de outras pesquisas, não foram observados comportamentos discriminatórios de teor racista entre as crianças nas instituições investigadas; pelo contrário, foram percebidos laços de amizade infantil construídos no cotidiano escolar de contexto migratório, onde as crianças haitianas se destacavam pelo protagonismo e liderança exercidos nas interações entre pares.

Aktivitas kesenian sempat mati suri selama masa pandemi di tahun 2019 yang diakibatkan oleh covid-19, baik yang ada di masyarakat umum, maupun di lingkungan sekolah. Dalam konteks pendidikan seni yang dilaksanakan di sekolah tentunya mendapatkan dampak negatif yang besar. Dampak tersebut adalah pembelajaran seni akan kesulitan dalam pelaksanaan praktek. Pasca pandemi, lahir beragam metode-metode pengajaran dalam lingkup seni, khususnya teater. Pelaksanaan pembelajaran praktek teater yang menyesuaikan kondisi covid tentu harus dilaksanakan di sekolah. Hampir dua tahun pembelajaran teater dilaksanakan secara daring sejak covid masuk di Indonesia. Pada tahun 2022, aturan pemerintah tentang Pembatasan Sosial Berskala Besar dicabut kemudian pelaksanaan pembelajaran diarahkan untuk tatap muka. Sehingga, sekolah kemudian dibuka kembali dalam pengajaran tatap muka. Akibat lamanya proses pembelajaran secara daring, sebagian besar guru-guru mengalami kendala dalam pengajaran praktek karena pembelajaran secara tatap muka dibutuhkan waktu untuk menyesuaikan kembali dan pengetahuan teater secara praktek mulai tumpul serta perlu di asah kembali. Atas dasar hal itu, pelatihan teater monolog menjadi satu bentuk atau upaya untuk pembelajaran teater setelah pandemi. Pada masa pandemi terdapat keterputusan pengetahuan sekaligus siswa mulai mendapatkan budaya baru, sehingga pelatihan ini mencoba mengangkat cerita lokal agar siswa mengetahui dan mendapatkan pengetahuan sejarah pahlawan lokal yaitu cerita kepahlawanan Datu Museng ketika di masa penjajahan. Pelatihan teater monolog ini akan dilaksanakan di sekolah SMK Telkom Makassar. Metode pelatihan yang dilaksanakan yakni, (1) mengidentifikasi cerita lokal yaitu cerita Datu Museng; (2) Proses kreatif: a. pembuatan dan pembedahan naskah, b. dramatik reading, c. blocking, d. memadukan musik dan properti, e. pemantapan aksi, dialog, musik, setting dan properti; dan terakhir adalah (3) Penyajian Pertunjukan.

Kampung Budaya Jalawastu di Brebes, merupakan satu-satunya kampung budaya di Jawa Tengah yang menggunakan Bahasa sunda dalam kehidupan kesehariannya. Letak geografisnya berada pada dataran tinggi di bawah kaki Gunung Kumbang, sehingga masyarakatnya mayoritas bertani dan berkebun. Masyarakat Kampung Budaya Jalawastu bersama pemerintah Brebes bekerja sama untuk melestarikan budaya, tradisi dan adat istiadat yang mereka percayai secara turun temurun. Salah satu tradisi yang masih dilestarikan dan dipertahankan hingga sekarang adalah upacara Ngasa. Upacara ini menjadi salah satu ikon tradisi dari Kampung Budaya Jalawastu yang patut diapresiasi. Upacara Ngasa biasa dilaksanakan selama satu tahun sekali, yaitu pada bulan ketiga tepatnya pada bulan maret selasa kliwon. Dalam upacara ini biasanya ditampilkan serangkaian pertunjukan seni khas Jalawastu, seperti ritual ciprat suci, Tari Perang Centong, Tari-tarian yang dibawakan oleh Laskar Wanoja, dan tari-tarian yang dibawakan oleh Laskar Jagabaya. Pada kenyataannya, kesenian Kampung Budaya Jalawastu jika dilihat dari aspek estetika terutama pada Tari Penyambutan Tamu masih perlu diadakannya revitalisasi agar menjadi sebuah tarian penyambutan yang menjadi ciri khas dari kampung budaya Jalawastu. Oleh karena itu, pengabdian ini bertujuan untuk memberikan pelatihan tari, bagi para pemudi Jalawastu yang biasanya menjadi penari untuk penyambutan tamu. Pelatihan tari yang tim lakukan adalah dengan menggunakan metode pelaksanaan secara langsung, pelatihan ini dapat menjadi sebuah kreativitas agar menjadikan Kampung Budaya Jalawastu memiliki ciri khasnya tersendiri. Tidak hanya itu, garapan musik iringan tari penyambutan tamu pun disusun bersama antara tim riset dengan masyarakat Jalawastu, dengan menyesuaikan karakteristik kesenian yang ada di daerah Brebes khususnya Jalawastu.  Kata Kunci: Kampung Budaya, Pelatihan, Tari, Jalawastu
