Published: September 2024

Maintaining a healthy nose is critical to overall well-being, especially for individuals undergoing rhinoplasty or septoplasty, where nasal splints play an important role in promoting recovery and minimising postoperative bleeding. This study looks at the potential of liquid silicone resin (LSR) in the manufacture of nasal splints, with a particular focus on the LSR moulding method. LSR, which is known for its easy flowability, precision and fast drying, proves to be an ideal material for the development of internal nasal splints. The use of LSR not only improves the quality of the resulting products, but also speeds up the manufacturing process. Laboratory-scale tests have been conducted to verify the safety and effectiveness of nasal splints produced using LSR moulding technology. The field of LSR moulding continues to evolve, positioning liquid silicone injection moulding as the primary method for manufacturing nasal splints and other medical devices. This study provides valuable insight into the versatile applications of LSR and paves the way for innovative solutions for nasal health. By exploring the possibilities of LSR in the manufacture of nasal splints, this study provides a comprehensive understanding of the potential advances in medical device manufacturing, contributing to continued progress in the field.

Published: September 2024

Background: Coronary heart disease (CHD) is a leading cause of mortality globally, with acute myocardial infarction (AMI) being a significant contributor. Historically considered a "men's disease," CHD is increasingly diagnosed in women, who often present with atypical symptoms, making diagnosis challenging and leading to suboptimal care. Age-specific differences in risk factors, clinical presentations, and angiographic outcomes in female AMI patients have not been extensively studied. Objective: This prospective observational study aimed to delineate age-related variations in risk factors, clinical presentations, and coronary angiographic outcomes among female patients with AMI, comparing younger (<55 years) and older (≥55 years) age groups. Methods: A total of 115 female patients with AMI were enrolled from December 2018 to November 2020 at Jawaharlal Nehru Medical College and Hospital. Participants underwent coronary angiography, and risk factors such as hypertension, diabetes, dyslipidemia, and smoking were assessed. Statistical analyses included chi-square and Student's t-test. Results: Among the participants, 38 were younger (<55 years) and 77 were older (≥55 years). Dyslipidemia was the most prevalent risk factor in both groups, with significant differences in hypertension (p=0.041), hypothyroidism (p=0.022), and family history of CAD (p=0.003) between age groups. Clinical presentation revealed typical angina as the most common in both age groups, with acute LVF significantly more prevalent in the elderly (p=0.021). Coronary angiography showed high prevalence of significant CAD in both groups, with age-related variations in the extent of disease. Conclusion: This study highlights age-specific differences in risk factors, clinical presentations, and coronary angiographic outcomes among female patients with AMI. These findings underscore the importance of tailored management strategies and targeted interventions for improving outcomes in female AMI patients of different age groups.
Ensuring that the prosecutor implements the principle of legality during the notification of suspicion
Authors: Kolot N. M.
Published: September 2024

The article establishes that in criminal proceedings granting a person the procedural status of a suspect in committing a criminal offense is an important decision that requires the validity of the suspicion and control over the legality of its adoption. The problematic issues of ensuring the implementation of the principle of legality by the prosecutor during the notification of suspicion have been studied. It has been established that the prosecutor’s provision of legality during the notification of suspicion consists in: strict observance of the procedure established by law; ensuring the legal subject conducting the criminal process and reporting the suspicion; in getting to know the rights of the participants in the proceedings and ensuring their realization of these rights; as well as compliance with legal requirements regarding procedural terms. It was established that criminal prosecution before the decision to notify a person of suspicion is a direct violation of the implementation of the principle of legality, since the person has not acquired the criminal procedural status of a participant, which he actually is at the time of the proceedings, not in form, but in essence, according to the criminal procedural law. It was noted that a person who has not acquired the legal status of a participant in criminal proceedings cannot exercise his «legal» rights, in particular the fundamental right to defense. Attention is drawn to the fact that a general violation of the principle of the legality of criminal proceedings, with the acquisition of relevant grounds and notification to the person of suspicion, the criminal process must comply with another procedure established by law, which is manifested in a clear outline of the legal position of the defense party in criminal proceedings, counting of established procedural terms, etc. It was concluded that the prosecutor, who is the procedural head in a specific criminal proceeding, can supervise the observance of laws during the notification of suspicion, in the form of: a preliminary prosecutor’s counter, by approving the notification of suspicion, revision of previous procedural decisions of the investigator, inquirer, checking at the same time, the validity of the notification of suspicion; personal making of legal decisions at the pre-trial investigation, in particular in the form of notification of suspicion personally by the prosecutor. It was proposed and argued that it would be appropriate to set the time limit for preparation for the defense after notification of suspicion at least 14 days before the completion of the pre-trial investigation in one of the forms provided for by the Criminal Procedure Code of Ukraine.

Currently, the most complete measure of community welfare is the happiness index because this measure is based on community subjectivity. This study aims to determine the effect of per capita income, minimum wage, income inequality and gross enrollment rates on the Happiness Index in Indonesia. The research objects are 34 provinces in Indonesia. The data used are secondary data for 2014, 2017 and 2021. The data source is the Indonesian Central Bureau of Statistics. Using the panel data regression, the results show that per capita income, income inequality, minimum wage and gross enrollment rates together have a significant effect on the happiness index. and partially the per capita income variable has no significant positive effect on the happiness index while income inequality has no significant negative effect on the happiness index, conversely the minimum wage variable and gross enrollment rate have a significant positive effect on the happiness index in Indonesia. In order to increase the happiness index, it is recommended that the provincial government periodically review the minimum wage policy, increase the gross enrollment rate and increase per capita income and reduce income inequality.

This ten-page visual, poetic essay captures my disenfranchisement from my own art and poetry, as well as the continuous instability of my life. I start with parental expectations, symbolized by negative space or violent lines and shapes, pondering the cost of these expectations on the joys and freedom of youth. I move into encounters of transphobic and racist bullying at primary school, a time when it was impossible to bear the terms for such experiences. This is followed by representations of abuse, only retroactively understood throughout the subsequent exploration of it, as well as the chronic deprivation of opportunity that these kinds of injuries cause. The exponential costs, particularly the emotional ones, that incur from the practical losses that come with life are then considered, along with the re-traumatization of simply trying to survive them. Finally, there are discordant uses of space, cluttered and overlayered images and words, alongside isolating negative spaces, to represent the constant feeling of failure, including being broken even during instances of stability or minor success.
Rethinking Propellant-Optimal Powered Descent Guidance
Authors: Lu Ping , Davami Christopher
Published: September 2024

The propellant-optimal powered descent solution requires a bang-bang thrust magnitude profile that switches instantaneously between the upper and lower bounds of the engine thrust. Implementing a bang-bang thrust pattern for guidance can be challenging for the engine and may cause practical and operational difficulties. Motivated by the observation that excellent propellant performance does not appear to be predicated on necessarily having a bang-bang thrust structure, a new powered descent guidance method is proposed in this work. The foundation lies in a propellant-optimal problem in which the thrust magnitude is parameterized by a user-prescribed continuous function of time. In particular, constant and linear functions are considered. The solution determines the optimal thrust direction, time of flight, and design parameters defining the thrust function. An indirect-method-based guidance algorithm is developed to solve this problem rapidly and reliably. Substantial evidence is provided to demonstrate that the solutions proposed in this paper in general yield a propellant consumption very close to that of the optimal bang-bang solution. Given its comparable propellant performance, implementability, and robustness, this paper makes a strong case that the proposed propellant-optimal powered descent guidance approach is preferred to the long-standing bang-bang guidance approach.
Systematic Experimental Evaluation of Aeroelastic Characteristics of a Highly Flexible Wing Demonstrator
Authors: Jayatilake Sanuja Delasalle , Lowenberg Mark , Woods Benjamin King Sutton , Titurus Branislav
Published: September 2024

This paper presents a comprehensive experimental analysis of the evolutionary modal characteristics of a highly flexible wing that exhibits bending–torsion coupling-driven instability. By implementing operational modal analysis on responses triggered by a combination of an external pulse-like stimulation and turbulence within the flow, this paper presents the airspeed-driven variations of the modal frequencies, damping ratios, and the underlying modal coupling behavior, leading to instability. This analysis is extended to varying the wing root pitch angles through which the effects of geometrical nonlinearity are exercised. Their effects are particularly noted on the hump feature of the airspeed-driven damping ratio locus of the mode responsible for instability. The decreasing critical damping ratio is shown to result in amplified turbulence-driven responses, which pose significant challenges to identification procedures by masking the visibility of other modes. Furthermore, through a novel technique used to analyze the modal coupling, the relative phase and magnitude properties of the coupled bending–torsion composition of the critical mode before and at flutter onset are evidenced experimentally. It is demonstrated that these relative participation measures provide a strong indication of the response content of the limit cycle oscillations that emerge after the flutter speed.
Improved Design Method for Hypersonic Intakes Using Pressure-Corrected Osculating Axisymmetric Flows Method
Authors: Musa Omer , Huang Guoping
Published: September 2024

The efficient design of air intake is crucial for high-speed airbreathing propulsion systems. This paper presents a novel design method that integrates the recently introduced internal conical flow M (ICFM) basic flowfield (Musa et al., “New Parent Flowfield for Streamline-Traced Intakes,” AIAA Journal, Vol. 61, No. 7, 2023, pp. 2906–2921) with the pressure-corrected osculating axisymmetric flows and streamline tracing techniques. The new design method takes into account the effects of lateral pressure gradients by incorporating pressure corrections into the original design method using crossflow velocity information from the ICFM flowfield. Additionally, new entrance and throat profiles are introduced for designing two hypersonic internal waverider intakes with shape transition. One intake is designed using the new method, and the other using the original method. Viscous simulations have been performed at design (i.e., Mach 6.0) and off-design (i.e., Mach 4.0 and 3.5) conditions. The results indicate that the pressure-corrected intake exhibits superior performance in terms of total pressure recovery and reduced flow distortion. This reveals that the new design method can achieve a smooth shape and efficient aerodynamic transitions between the intake entrance and throat. The new entrance and throat profiles realized better performance than the typical ones. The startability analysis reveals that the Van Wie curve controls the considered intakes. Thus, combining the pressure-corrected osculating axisymmetric flows with the ICFM flowfield enhances the performance of hypersonic intakes, making this approach a promising avenue for future hypersonic vehicles.
Gate-Based Variational Quantum Algorithm for Truss Structure Size Optimization Problem
Authors: Xu Yusheng , Wang Xiaojun , Wang Zhenghuan
Published: September 2024

Quantum computing has become a pivotal innovation in computational science, offering novel avenues for tackling the increasingly complex and high-dimensional optimization challenges inherent in engineering design. This paradigm shift is particularly pertinent in the domain of structural optimization, where the intricate interplay of design variables and constraints necessitates advanced computational strategies. In this vein, the gate-based variational quantum algorithm utilizes quantum superposition and entanglement to improve search efficiency in large solution spaces. This paper delves into the gate-based variational quantum algorithm for the discrete variable truss structure size optimization problem. By reformulating this optimization challenge into a quadratic, unconstrained binary optimization framework, we bridge the gap between the discrete nature of engineering optimization tasks and the quantum computational paradigm. A detailed algorithm is outlined, encompassing the translation of the truss optimization problem into the quantum problem, the initialization and iterative evolution of a quantum circuit tailored to this problem, and the integration of classical optimization techniques for parameter tuning. The proposed approach demonstrates the feasibility and potential of quantum computing to transform engineering design and optimization, with numerical experiments validating the effectiveness of the method and paving the way for future explorations in quantum-assisted engineering optimizations.

The paper offers a mathematical model of a computer attack in conditions of limited protection capabilities and considers the issues of constructing experimental predictive models of incidents related to vulnerabilities of information systems and models of computer attacks for the purpose of mining cryptocurrencies. Previously the author developed a method of calculating the evaluation level of security of information systems (is) based on the analysis of the incidents, the forecasting model as a continuous function of time function of risk and the definition on the basis of a parameter characterizing the degree of protection of IP – time safe operation. The mathematical model of a computer attack is constructed using the apparatus of probability theory and combinatorial analysis. Predictive models for the occurrence of incidents related to information system vulnerabilities and attack models for mining cryptocurrencies are based on the previously developed tools for building predictive models of dynamic systems. Estimates of the time of safe operation of the information system, in respect of which attacks are implemented for the purpose of mining cryptocurrencies, are obtained.

В настоящее время операторское управление сложными производственными объектами не сводится к простому наблюдению за ходом технологического процесса и своевременному адекватному реагированию на разного рода нештатные ситуации. Зачастую оператору приходится принимать непосредственное участие в управлении объектом для достижения наилучших показателей, формируя задания для локальных регуляторов. В обстановке большой загруженности оператора вследствие его усталости и рассеянности внимания возрастает вероятность принятия ошибочных решений, особенно если оператор не обладает достаточным опытом работы. В данной статье рассматриваются перспективы решения этих проблем путем разработки системы поддержки принятия решений на основе интеллектуальных технологий и ее интегрирования в состав существующей системы управления установкой металлизации.

Authors: Ковалев Д.П. , Ковалев П.Д.
Published: September 2024

Рассмотрены результаты изучения волнового режима в заливе Терпения и в районе порта г. Поронайск с использованием данных регистраторов волнения, установленных в порту г. Поронайск и у мыса Терпения в 2008 и 2009 гг. Показано, что поскольку порт находится на р. Поронай, ветровое волнение значительно ослабляется. В то же время высота приливов в порту может достигать 1,5 м и наблюдаются сейши с периодом около 7 ч. Показано, что сейши с периодом 7 ч соответствуют первой моде собственных колебаний морской акватории, которая включает область от залива Терпения до залива Мордвинова. Максимальная высота волны для сейши с этим периодом может достигать 72 см от подошвы, что может приводить к экономическим и экологическим проблемам в работе порта. Анализ волнения в диапазоне волн цунами показал наличие в заливе Терпения шельфовых сейш с периодом около 2,7 ч, для которых добротность акватории равна 23,1. При этом сейши могут значительно усиливаться при подходе к порту волн цунами на близких периодах.

The article considers the results of studying the wave mode in the Terpeniya Gulf and in the area of the Poronaysk port using the data of wave recorders installed in the Poronaysk port and close to the Cape Terpeniya in 2008 and 2009. It is shown that since the port is located in the Poronai River, the wind waves are signifi cantly weakened. At the same time, the height of tides in the port can reach 1,5 meters and seiches are observed with a period of about 7 hours. It is shown that seiches with a period of 7 hours correspond to the first mode of eigen-values oscillations of the sea area, which includes the area from Terpeniya Gulf to Mordvinov Bay. The maxi-mum wave height for a seiches with this period can reach 72 cm, which can lead to economic and environmental problems in the port operation. Analysis of waves in the tsunami wave range showed the presence of shelf seiches in Terpeniya Bay with a period of about 2,7 hours, for which the quality factor of the water area is 23,1. In this case, seiches can significantly increase when tsunami waves approach the port at close periods.

Идеи И.С. Кулаева, одного из пионеров в области биохимии и клеточной биологии неорганических полифосфатов, в настоящее время стали общепризнанными в науке и продолжают развиваться в ИБФМ РАН. В литературе имеются многочисленные доказательства того, что у млекопитающих эти полимеры играют важную роль в системе свертывания крови и воспалительного ответа, в образовании апатита костной ткани, в передаче нервных сигналов, функционировании ионных каналов и формировании амилоидов. Эти свойства полифосфатов, а также широкое использование их в пищевой промышленности и других сферах экономики, делает актуальным разработку высокоточных методов их анализа. Одним их эффективных методов анализа полифосфатов является энзиматический метод, когда обработка образцов специфическими экзополифосфатазами приводит к высвобождению фосфата, определяемого стандартными колориметрическими методами. Дрожжевые экзополифосфатазы, полученные из клеток дрожжей-суперпродуцентов этих ферментов, эффективны как аналитический реагент для высокоспецифичного и чувствительного анализа полифосфатов в биологических образцах. С помощью эндополифосфатаз возможно получение полифосфатов заданной длины для исследовательских целей и разработки лекарственных средств.

The Ideas of I.S. Kulaev, pioneer in biochemistry and cell biology of inorganic polyphosphates, has now become widely accepted and developed in IBPM RAS. The evidences were obtained in favor of the important role of these polymers in the blood coagulation, inflammatory response, in bone tissue apatite formation, in transmission of nerve signals, in functioning of ion channels, and formation of amyloids. These properties of polyphosphates, as well as their widespread use in the food industry and other sectors of the economy, make relevant the development of highprecision methods for their analysis. The enzymatic method is based on the treatment of samples with specific exopolyphosphatases releasing phosphate, which is determined by standard colorimetry. Yeast exopolyphosphatases obtained from overproducing strains are an effective analytical reagent for highly specific and sensitive analysis of polyphosphates in biological samples. With the help of endopolyphosphatases, it is possible to obtain polyphosphates of a given length for research purposes and drug design.

Exploring Shostakovich’s creative process based on manuscripts of «Twenty-Four Preludes for Piano»
Authors: Лукьянов А.В.
Published: September 2024

В статье рассматривается творчество Д.Д. Шостаковича с точки зрения «моцартовского» и «бетховенского» типов творческого процесса, издавна выделяемых в музыкознании. «Моцартовский» тип характеризуется сочинением в уме, минимальным количеством черновиков и исправлений, «бетховенский» – развёрнутой эскизной работой с обилием черновиков. Достаточно многочисленные самонаблюдения Шостаковича в основном указывают на преобладание «моцартовского» начала над «бетховенским», что в целом подтверждается и изучением эскизов его произведений в самых разных жанрах. Не составляют исключения и «24 прелюдии» для фортепиано, рассматриваемые в настоящей публикации. Эскизы прелюдий изучались методом сравнительного анализа, при котором рукописи сопоставлялись с опубликованным текстом. Именно такой подход позволяет выявить не зафиксированные в черновиках исправления, вносившиеся композитором при переписывании набело и чаще всего затрагивавшие синтаксический уровень организации музыки, а в нём в первую очередь звуковысотность и ритм. Среди звуковысотных корректировок нами отмечено большое число полутоновых смещений, что даёт основание рассматривать такую правку в качестве одного из проявлений стиля композитора. В итоге, проявлений типично «бетховенского» творческого процесса нами не обнаружено, но факт наличия исправлений позволяет говорить об органичном сочетании в «24 прелюдиях» «моцартовского» типа и индивидуальных стилистических черт Шостаковича.

The article considers the D.D. Shostakovich`s output in terms of Mozartean and Beethovian types of creative process, which have long been distinguished in musicology. The Mozartean type is characterized by composition in mind, minimum number of drafts and corrections, the Beethovian type is characterized by extensive sketchy work with lots of drafts. Shostakovich’s rather numerous self-observations mainly indicate the predominance of Mozartean type over Beethovian one. This point of view is generally confirmed by the exploring of sketches of Shostakovich’s opuses in various genres. "24 Preludes for piano" analysed in this publication are not an exception. Sketches of preludes were explored by the method of comparative analysis, comparing sketches with published versions. Such approach allowed to identify the corrections which had not been fixed in the drafts and were made by the composer a fair copy. Most of corrections concerned the syntactic level of organization of music and first of all its pitch and rhythm. Among the pitch corrections a plenty of semitones displacements were noted, which gave reason to consider such corrections as one of the manifestations of the composer's style. As a result, typical manifestations of Beethovian type of creative process were not found. But the fact of existing drafts corrections allows to suggest a natural combination of Mozartean type and individual Shostakovich`s stylistic features in the "24 Preludes for Piano".

В целях снижения затрат на обслуживание и послеремонтное тестирование летательных аппаратов предлагается использование формальных моделей. Жизненно значимый агрегат представляется в виде совокупности элементов с определенными функциональными признаками и причинно-следственными связями между ними. Модель позволяет выявлять первопричины нарушения рабочего состояния агрегата, что способствует построению более эффективных программ ремонта за счет сокращения времени поиска неисправности. Благодаря возможности определения всех последствий выхода из строя одного или нескольких узлов конструкции может быть установлен оптимальный объем послеремонтных испытаний, ограниченный тестированием элементов, входящих в цепочку отказов. Возможность наблюдения за расходованием ресурса позволяет прогнозировать момент наступления предельного состояния любого агрегата и, таким образом планировать циклы межполетного обслуживания изделия.

In order to reduce the maintenanse costs, as well as to optimize after repair aircraft testing programs, the use of formal models is proposed. A vital aggregate is represented in the form of a set of elements with certain functional signs and causal relationships between them. The model alows to identify the root causes of the violation of the operating state of the unit which contributes to the construction of more effective repair programs by reducing the time of troubleshooting. Due to the ability to determine all the world on structural units to optimal amount After Test can be limited by consequences of the failure of one or more structural units the optimal amount of after-repair tests can be established, limited by testing the element included in the failure chain. The ability to monitor the consumption of the resource allows us to to predict the moment of onset of the limit state of any unit and thus plan the cycles of inflight maintenanse of the product.
