Published: July 2022

Due to the increasing demand in films and games, synthesizing 3D avatar animation has attracted much attention recently. In this work, we present a production-ready text/speech-driven full-body animation synthesis system. Given the text and corresponding speech, our system synthesizes face and body animations simultaneously, which are then skinned and rendered to obtain a video stream output. We adopt a learning-based approach for synthesizing facial animation and a graph-based approach to animate the body, which generates high-quality avatar animation efficiently and robustly. Our results demonstrate the generated avatar animations are realistic, diverse and highly text/speech-correlated.

Authors: Bravo Fernanda , Ton Bárbara , Baldon Isabella , Bravo Paula
Published: July 2022

Objective: Silver-Russell syndrome (SRS) is a rare but well-recognized condition associated with classic phenotypic characteristics. This article aims to describe a patient with SRS, in order to help professionals in the diagnosis and adequate therapeutic management, since the early approach results in a better prognosis. METHODS: This is a case report of a male child, 1 year and 4 months old, admitted to an infirmary, who was diagnosed with SRS. Patient information was collected with the family during hospitalization. Analysis of medical records and literature review was also performed. RESULTS: A patient with chronic malnutrition, who had macrocranial physical examination, elongated facies, large ears with low implantation, occipital capillary rarefaction, micrognathia, hypospadias, 5th finger clinodactyly and delayed developmental milestones, received a diagnosis of SRS during hospitalization. Complementary exams ruled out pathologies of the gastrointestinal tract and in the speech-language evaluation, swallowing disorders were not detected. An enteral diet for nutritional recovery was initiated, but the patient maintained insufficient weight gain and an important food aversion, being the patient submitted to gastrostomy. On an outpatient return after hospital discharge, the patient remained low weight gain despite the use of hypercaloric formula and appropriate volume for his age. CONCLUSION: SRS leads to a wide spectrum of abnormal physical characteristics and functional abnormalities. Multidisciplinary monitoring and early, specific intervention are necessary for better management of this group of patients.

Authors: Almendra Margarida , Alves Rui , Lima Sofia , Silva Tiago
Published: July 2022

A soft tissue thoracic mass differential diagnosis includes congenital, inflammatory/infectious and neoplasic causes. A neoplasic aetiology - in which sarcoma is included - can be a challenging diagnosis, given its unpainful and slow growth nature. Despite being unusual, sarcoma must be considered in the presence of a gradually enlarging unpainful mass in the trunk or extremities, as this is the most common form of presentation. Quite often, the histologic exam of a soft tissue mass is essential for diagnosis and treatment planning.

Authors: Sharma Bhargava Palbi
Published: July 2022

The Greek economic crisis caused chaos in the lives of citizens and as a result many individuals suffer from anxiety and stress. Neoliberal markets have assisted in facilitating alternative self-care rituals to help citizens of Athens take control of their mental health. These markets provide alternative healing services and products to treat individuals from everyday stress and anxiety. This research project utilizes ethnographic methodology to understand how self-care rituals, such as coffee cup readings, evil eye exorcism, healing stones and evil eye merchandise play a significant role in improving mental health in the lives of adult Greek citizens. The interlocutors report that the use of alternative self-care rituals have positive therapeutic benefits in their lives. These products and services embody a rich cultural history, but over time are questioned and stigmatized due to the rationality in relation to current scientific advancements. This paper explores the sociocultural significance of alternative self-care rituals and understanding of mental health in Athens, Greece. This study is an effort to show despite the stigma towards alternative healing methods, these methods deserve our attention as they report to have a significant impact on consumers lives and identities.

Authors: Иванов Ф.И. , Захаров Ю.А. , Исакова Е.В.
Published: July 2022

В работе с использованием методов избирательной кристаллизации (декорирования) и оптической микроспектрофотометрии, наблюдением эффекта Келдыша-Франца в нитевидных кристаллов азидов тяжелых металлов (b-PbN6, AgN3), исследована топография распределения зарядовых состояний, доменов сильного поля (ДСП), и обсуждены возможные механизмы их образования. Использование методик декорирования на разных уровнях разрешения, выявляемых с помощью оптической и электронной микроскопии, позволило наблюдать электрически активную информационную структуру в азидах свинца и серебра, в которой локализуются процессы, протекающие при энергетических воздействиях радиации, электрического поля и температуры. Картины декорирования в НК АТМ позволили впервые визуализировать сложные элементы электрического микро- и макрорельефа и установить связь электрического рельефа с полями упругих напряжений у дислокаций или в области полос скольжения и оценить напряженность электрических полей создаваемых в этих структурах. Обоснованно и доказано существование диффузионно-дрейфового механизма формирования ДСП связанного с разделением заряженных точечных дефектов (вакансий, междоузельных атомов) в полях упругих напряжений, создаваемых структурными дефектами (дислокациями, полосами скольжения или зародышами новой фазы). Исходя из диффузионно-дрейфового механизма формирования доменной электрической структуры в НК b-PbN6 вокруг дислокаций и полос скольжения, произведена оценка концентрации ионов Pb+ или Pb2+ в области пространственного заряда краевой дислокации и величину напряженности электрического поля E»106 В/м в ДСП. Оценена объемная концентрации заряженных частиц из теории Дебая-Хюккеля по формуле , в которой LD– Дебаевская длина экранирования (определяемая экспериментально), дает величину приблизительно 1022 м‑3, что соответствует поверхностной плотности заряда 1014 м-2, наблюдаемой по картинам декорирования. Наличие ДСП подтверждает сегнетоэлектрическую природу азидов свинца и серебра.

Published: July 2022

Новые пьезоэлектрические материалы всё более востребованы для использования в различного рода устройствах (датчиках и т.д.), работающих в широком диапазоне рабочих температур. Технология поверхностных акустических волн (ПАВ) позволяет проводить совместную обработку сигналов с многофункциональных сенсорных элементов датчиков. Новый кристалл YBa3(PO4)3имеет кубическую симметрию и обладает пьезоэлектрическими свойствами. В работе представлено численное исследование свойств поверхностной акустической волны (ПАВ) в кристалле YBa3(PO4)3. Фазовая скорость ПАВ, коэффициент электромеханической связи и угол отклонения потока энергии волны исследуется для различных кристаллических срезов кубического кристалла YBa3(PO4)3. Для Z-среза и направления распространения волны вдоль оси X+45° показано, что ПАВ имеет максимальное значение коэффициента электромеханической связи (0,17%) в кристалле. Для Z+45°-среза и направления распространения волны вдоль оси X коэффициент электромеханической связи равен 0,1%. Оба эти среза кристалла представляют потенциальный интерес для ПАВ-устройств.
ВЛИЯНИЕ КОЛИЧЕСТВА АТОМОВ МЕТАЛЛА НА МЕХАНИЧЕСКИЕ СВОЙСТВА КОМПОЗИТА НИКЕЛЬ/СКОМКАННЫЙ ГРАФЕН
Authors: Сафина Л.Р. , Крылова К.А. , Баимова Ю.А.
Published: July 2022

Методом молекулярной динамики изучено влияние соотношения атомов металла и углерода на механические свойства композита никель/графен. Рассмотрены четыре структуры с разным числом атомов никеля от 1344 до 4992. Предшественником композита является скомканный графен, поры которого заполнены наночастицами никеля разного размера. Для получения композита используют выдержку при комнатной температуре с последующим гидростатическим сжатием при 1000 К. Показано, что полученный композит имеет хорошие прочностные характеристики и высокую пластичность для любого рассмотренного количества атомов никеля в структуре. Однако с увеличением числа атомов никеля в системе прочность композита снижается. Следовательно, для получения композита с улучшенными механическими свойствами желательно использовать наночастицы небольших размеров, чтобы они могли равномерно распределяться внутри пор скомканного графена, способствуя возникновению новых химических связей между отдельными элементами композита.

Исследование механических свойств материалов на основе никелида титана, возникающих в ходе термоупругих мартенситных превращений, в том числе реактивных напряжений представляют огромный интерес. Эффект генерации реактивных напряжений в материалах с памятью формы оказывает влияние на различные области техники. Так, в материалах с эффектом памяти формы, выступающих в качестве механических преобразователей энергии и в качестве силовых элементов приводов используются условия, при которых происходит фиксирование деформации. Данное использование предполагает стабильность свойств и рабочих параметров в такого типа устройствах. В работе были исследованы реактивные напряжения, возникающие в образцах сплавов на основе никелида титана при фиксировании деформации, которая препятствует осуществлению эффекта памяти формы в процессе циклирования мартенситных превращений. Предполагается, что циклирование мартенситных превращений может привести к изменению реактивных напряжений вследствие структурной перестройки материала, что в свою очередь повлияет на рабочие характеристики узлов и агрегатов из сплавов на основе никелида титана. Показано, что уровень реактивных напряжений, развиваемых в образце в цикле нагрев-охлаждение уменьшается в последующих циклах. Наблюдаемое упрочнение от цикла к циклу, в условиях действия реактивных напряжений может характеризовать явление фазового наклёпа.

В работе описаны результаты моделирования температурного воздействия единичного лазерного импульса на легирующую обмазку, нанесенную на нержавеющую хромоникелевую сталь 12Х18Н10Т. Целью моделирования являлось определение возможности нагрева поверхности нержавеющей стали в расширенном диапазоне энергии импульса (0,08-1,34 Дж) до температур интенсивных диффузионных процессов элементов легирующей обмазки. Поставленная цель решалась путем разработки геометрической и численной моделей. Моделирование проводилось в программном комплексе «Elcut 5.1», где решалась задача нестационарной теплопередачи для расчета переходного и установившегося температурного поля с учетом теплообмена элементов системы «окружающая среда-обмазка-образец». Проведенное моделирование позволило определить зависимости глубины, температуры и времени нагрева поверхностного слоя образцов от режимов импульсного излучения. Так, например, установлено, что при воздействии импульса лазерного излучения, сфокусированного в пятно диаметром 0,5 мм, при энергии импульса 0,92 Дж и длительности 0,5 мс, стальная основа нагреется на глубину 10 мкм до температуры 1600±50 °С. На глубине 100 мкм сталь нагревается до температуры 800-950 °С, что свойственно активному протеканию диффузионных процессов. Отметка глубиной 150 мкм характеризуется нагревом до 600-650 °С, что соответствует температуре высокого отпуска, при котором наблюдаются изменения кристаллической структуры. На основании полученных данных построены кривые, описывающие зависимость температуры стали на разной глубине, в разные моменты воздействия единичного лазерного импульса. Результаты моделирования подтверждены экспериментальными данными, а именно: установлена толщина модифицированных поверхностных слоев образцов, значение которой варьирует в зависимости от режимов лазерной обработки и составляет в среднем 100-200 мкм; определена микротвердость диффузионного слоя; проведены элементный и рентгенофазовый анализы. Установлено соответствие между результатами численного моделирования и полученными экспериментальными данными.

Published: July 2022

Увеличение масштабов промышленного освоения литых алюмоматричных композитов сдерживается недостаточной проработанностью вопросов их рециклинга. Сокращение безвозвратных технологических отходов и выявление эффективных подходов к рециклингу отработанных изделий будет способствовать снижению стоимости производства продукции из литых композиционных материалов. Одним из наиболее экономически привлекательных вариантов переработки отходов производства и потребления алюмоматричных композитов является прямой переплав для повторного использования при получении отливок и слитков, однако в этом случае необходимо принимать во внимание вероятность деградации армирующей фазы. В настоящей работе рассмотрен механизм протекания физико-химических процессов взаимодействия компонентов литых алюмоматричных композитов АК12оч + 10 об.% B4C при их переработке методом прямого переплава. Экспериментально показано, что при повторных переплавах происходит увеличение доли фазы Al3BC в структуре композитов, что является следствием интенсификации межфазных реакций на границах раздела. Состав и количество продуктов взаимодействия алюминиевого расплава с карбидом бора будут зависеть от температуры процесса и продолжительности их контакта до момента кристаллизации алюмоматричного композита. Расчетным путем определено, что температура перегрева литых алюмоматричных композитов с карбидом бора при их рециклинге не должна превышать 858 ºC в связи с изменением термодинамических условий взаимодействия компонентов, сопровождающимся резкой интенсификацией процесса деградации армирующих частиц.

Published: July 2022

Determining protein-ligand interaction characteristics and mechanisms is critical in the drug discovery process. Here we review recent progress and successful applications of a systematic protein-ligand interaction fingerprint (IFP) approach for investigating proteome-wide protein-ligand interactions for drug development. Specifically, we review the use of this IFP approach for revealing polypharmacology across the whole kinome, predicting promising targets from which to design allosteric inhibitors and covalent kinase inhibitors, uncovering the binding mechanisms of drugs of interest, and demonstrating resistant mechanisms of specific drugs. Together, we demonstrate that the IFP strategy is efficient and practical for drug design research and development in the current era of big data.

Published: July 2022

Bicyclo[1.1.1]pentanes (BCPs) are of great interest to the agrochemical, materials, and pharmaceutical industries. In particular, synthetic methods to access 1,3-dicarbosubsituted BCP-aryls have recently been developed but most protocols rely on stepwise C-C bond formation via initial manipulation of BCP core to make the BCP-electrophile or -nucleophile followed by a second step (e.g., transition-metal mediated cross-coupling step) to form the second key BCP-aryl bond. Moreover, despite prevalence of C-F bonds in bioactive compounds, one pot, multicomponent cross-coupling methods to directly functionalize BCP to the corresponding fluoroalkyl BCP-aryl scaffolds are lacking. In this work, we describe a conceptual different approach to access diverse (fluoro)alkyl BCP-aryls at low temperatures and fast reaction times enabled by an iron-catalyzed multicomponent radical cross-coupling reaction from readily available (fluoro)alkyl halides, bicyclo[1.1.1]pentane, and Grignard reagents. Further, experimental and computational mechanistic studies provide insights into mechanism and ligand effects on the nature of C-C bond formation. Finally, these studies are used to develop a new method to rapidly access synthetic versatile 1-(fluoro)alkyl,3-bromo and -iodo BCPs via bisphosphine iron catalysis.

Published: July 2022

La presente investigación de revisión documental tiene como objetivo explicar cómo se promueve el pensamiento crítico (PC) en la escuela desde el nivel inicial hasta el término  de la educación básica regular,  a través de una revisión minuciosa en bases de datos confiables desde la perspectiva de diversos autores que  muestran ideas claras y precisas acerca del uso de distintas estrategias que sirven para abordar este pensamiento desde las instituciones educativas, las mismas que ayudan a fortalecer en los estudiantes sus habilidades de orden superior debido a que en la actualidad se puede verificar que los niveles de desarrollo del PC son bajos,  permitiendo afirmar que es necesario estimularlo en la actualidad. A su vez, en los resultados se pudo constatar que las investigaciones bibliográficas realizadas se relacionan con las diversas estrategias que se deben utilizar para desarrollar el PC en los estudiantes del siglo XXI, como herramienta necesaria para actuar en los diversos entornos. Con ello se concluye que el déficit de PC en los estudiantes de EBR en los diferentes programas educativos, se debe fundamentalmente a que el docente no impulsa proyectos innovadores que desarrollen la creatividad y resolución de problemas, en escenarios que le permitan interactuar y tomar decisiones coherentes.

Published: July 2022

To enable large-scale application of polygenic risk scores (PRSs) in a computationally efficient manner, we translate a widely used PRS construction method, PRS–continuous shrinkage, to the Julia programming language, PRS.jl. On nine different traits with varying genetic architectures, we demonstrate that PRS.jl maintains accuracy of prediction while decreasing the average runtime by 5.5×. Additional programmatic modifications improve usability and robustness. This freely available software substantially improves work flow and democratizes usage of PRSs by lowering the computational burden of the PRS–continuous shrinkage method.

In this study, numerical analysis and experiments were performed to analyze the viscous damping effect according to the shape of the chamber skirt of the breakwater-linked inclined oscillating water column wave energy converter. Experiments were conducted using a two-dimensional mini wave tank and verified by comparing the results of a computational fluid dynamics numerical analysis. Pointed and rounded skirts were modeled to compare the effect of viscous damping when incident waves enter the chamber, and the difference in the displacement of the water surface in the chamber was compared according to the wave period for the two skirt shapes. The wave elevation in the chamber in the rounded-skirt condition was larger than the pointed-skirt condition in all wave periods, which was approximately 47% greater at 0.9 s of the incident wave period. Therefore, extracting the maximum energy through the optimal orifice is possible while minimizing the energy attenuation in the rounded-skirt condition.

Background: Timor-Leste has made good progress in reducing maternal and infant mortality in the last decade, but major challenges remain, with 51% of women giving birth at home and 43% without a skilled provider. There are many barriers that affect access to and use of health facilities for birth. An underexplored aspect in Timor-Leste is the role of disrespect and abuse during childbirth. This study aimed to explore the types of physical and verbal abuse experienced by women in urban health facilities, and at what stage of the birthing process these types of abuse are most likely to occur. Subjects and Method: This was a qualitative study used in-depth interviews. A sample of 10 women who had recently given birth at two urban birth facilities in Dili, Timor-Leste. Women were asked about their treatment and adverse experiences during labor and birth. Notes were taken during the interviews, transcribed and coded, and themes were analyzed around types of abuse and when they occurred. The data were analyzed by narratively. Results: Women experienced many different forms verbal and physical abuse from their birth attendant. Verbal abuse tended to occur earlier in labor, largely in response to women crying out in pain during contractions. Physical abuse was more likely to occur during the birth as well as during delivery of the placenta and perineal suturing. Conclusion: Women described verbal abuse most often during labor and birth, and physical abuse during birth, placenta expulsion and perineal suturing.

Archival Materials on the Development of Regulatory Framework for Manufacture of Military Goods at the Urals Mining Plants in the First Half of the 19th Century
Authors:   First President of Russia B. N. Yeltsin Ural Federal University, Yekaterinburg, Russian Federation, Alexandr A. Bakshaev
Published: July 2022

The article characterizes archival sources on creation and improvement of legal framework governing the manufacture of military goods in the mining industry of the Urals in the first half of the 19th century. The chronological framework of the study is determined by the fact that it was during this period that special committees and commissions of military and mining departments representatives were preparing rules and instructions to govern the production and acceptance of military products. The development of legal and regulatory framework for military contracts is one of the least studied issues in the history of the Russian military economy. The sources are fragmentary; they are stored in the fonds of both federal and regional archives. Therefore, the purpose of the work is to identify archival materials on normative work of military and mining authorities in the field of military contracts. In the federal archives, documents devoted to this problem are stored in the fonds of central bodies of military and mining administration of the first half of the 19th century. The Berg Collegium materials from the Russian State Archive of Ancient Acts (RGADA) and those of the Mining Department from the Russian State Historical Archive (RGIA) enable the study of the activities of committees created in 1804 and 1808 for the development of military products acceptance procedure in the state-owned factories of the Urals. Participation of the military command and control bodies in the preparation of these normative acts can be traced in the documents from the Russian State Military Historical Archive (RGVIA). Moreover, the correspondence of military and mining authorities testifies of unsatisfactory fulfillment of military contracts by mining plants, which was the reason for creation of rules for acceptance of military products and their processing. The fonds of the federal archives also store documents on the Artillery and Mining Departments activities in improving regulatory framework in the 1820s–40s. New rules for the acceptance of guns, shells, and metals were outlined and approved in 1831 and 1846. In the fonds of regional governing bodies and industries from the State Archive of the Sverdlovsk Region (GASO), documents have been identified on the development of rules for military goods acceptance procedure, their delivery to mining plants, use in manufacture, military receiving clerks’ activities. Materials of the GASO fond of the chief artillery inspector at the factories of the Urals provide data on his participation in the work of the committee created in the 1820s.

Modern imaging techniques including various echocardiographic technologies have become firmly established in the practice of cardiac surgery. The method of intraoperative transesophageal echocardiography (TEE) is of particular significance for ensuring the safety of patients during open heart surgery. This method is necessary for performing reconstructive interventions on the valve apparatus of the heart in patients with initial myocardial dysfunction to assess the anatomical and functional state of the heart and its structures at all stages of surgical treatment. Information obtained in the operation room using TEE allows the surgeon to choose the optimal tactics of surgical intervention, evaluate the results of surgery, and predict the course of early postoperative period. The presented clinical case demonstrates the capabilities of intraoperative use of TEE during the Ozaki procedure in a patient with congenital bicuspid aortic valve.
Analyzing Reinforcement Learning Algorithms for Nitrogen Fertilizer Management in Simulated Crop Growth
Authors: Vogt Michael , Rosman Benjamin
Published: July 2022

Establishing intelligent crop management techniques for preserving the soil, while providing next-generational food supply for an increasing population is critical. Nitrogen fertilizer is used in current farming practice as a way of encouraging crop development; however, its excessive use is found to have disastrous and long-lasting effects on the environment. This can be reduced through the optimization of fertilizer application strategies. In this work, we apply a set of reinforcement learning algorithms – the DQN, Double DQN, Dueling DDQN, and PPO – to learn novel strategies for reducing this application in a simulated crop growth setting. We provide an analysis of each agent’s ability and show that the Dueling DDQN agent can learn favourable strategies for minimizing nitrogen fertilizer application amounts, while maintaining a sufficient yield comparable to standard farming practice.
Memory Requirements for the Detection of Impostor Nodes in Wireless Sensor Networks
Authors: Gruner Stefan , Krajnc Dylan , van Rooyen Johan Pieter
Published: July 2022

This paper shows how it is at least in principle possible to detect impostor nodes in wireless sensor networks with a quite simplistic detection algorithm by purely statistical means and merely from external observation without any knowledge of the impostor’s inter- nal composition. This method, however, requires considerable volumes of internal memory for any WSN node on which such detection algorithms are supposed to be implemented.
