Authors: Malikova Natalia , Zborovsky Garold
Published: June 2023

This article examines the activities of a unique sociological museum, based out of the Ural Federal University in Yekaterinburg. The museum is dedicated to the life and work of Professor L.N. Kogan, one of the highest profile Soviet/Russian sociologists of the second half of the XX century. The authors of the article focus on the goals, methods, style of work of the museum and its significance when it comes to reproducing the history of sociology in the Urals. Described are the main forms and types of the museum’s educational activities among students, postgraduates, applicants receiving sociological education and professional training, as well as teachers and numerous guests of the university, city and region. The article shows how Kogan’s image is constructed in the museum’s space; also considered are the potential of his creativity and its implementation in theoretical and empirical research. A large number of documents, artifacts, and various sources gathered in the museum allow visitors via training sessions and tours to get an idea about the main stages of Kogan’s life, studies, work, and his achievements in scientific, journalistic, and social activities. In the museum you can get acquainted with the style and methods of the scientist’s work, the specifics of his interactions with students, postgraduates, applicants and sociologist colleagues. Almost all of L.N. Kogan’s monographs and most important publications are presented on the shelves. The museum’s exposition demonstrates the breadth of his scientific interests, which, in addition to sociology, extended to such areas as philosophy, political science, cultural studies, art and theater. The museum gives you a vivid idea of the personality of the scientist, his willingness to impart knowledge upon people, his professionalism in the study of social processes, how skilled he was in the culture of academic communication, as well as his ability to instill optimism into people. In addition, thanks to the abundance of historical documents, visitors have the opportunity to trace the history of the formation and development of sociology at the Ural University and the region over a period of 50 years.

Authors: Oliveira Leandro , Manoel Catarina , Ribeiro Márcia , Pedro Diogo , Simões Rodrigues Catarina , Rossoni Carina
Published: June 2023

Food labeling is important for consumers to have access to accurate nutritional information and to guide them in choosing healthier foods, but its correct understanding and use by consumers is equally important. This study aims to assess higher education students' knowledge of labeling and relate it to demographic factors. This is an exploratory observational study whose data collection was carried out through an online questionnaire, in the period between November and December 2022. In this study, 124 higher education students participated, mostly female (74.2%), living in the Lisbon metropolitan area (97.9%), who did not practice physical exercise/sport (98.4%), and who had no type of food allergy or disease (84.7%). The mean age of the participants was 20.1 ± 1.9 years old. The mean score for knowledge about food labeling was 5 ± 1.8, with a maximum of 8 points. No relationship was found between knowledge about labeling with demographic characteristics. However, the results point to the need to increase knowledge about food labeling, as well as about the interpretation of nutritional information.
The Impact of Transformational Leadership and Transactional Leadership on Voice Behavior and Creative Behavior through Job Crafting
Authors:   IAGBT, Cui Hang-Hang , Kwon Hyeok-Gi
Published: June 2023

Purpose - In the face of an increasingly competitive business environment and the growing complexity and dynamism of work activities, employee voice and creative behaviors are essential to organizational growth and survival. Consequently, this study examines how to increase voice and creative behaviors in organizational life using transformational leadership and transactional leadership as the entry points, and selecting job crafting as the mediating variable.
Design/Methodology/Approach - A hypothesized model was developed to examine the relationship between the constructs. The sample for the study comprised 364 Chinese employees. Data were analyzed using SPSS and structural equation modelling in AMOS.
Findings - Transformational leadership and transactional leadership positively impact job crafting, voice behavior, and creative behavior, complementing the existing theory. Furthermore, this study finds that through job crafting, transformational leadership has an enhanced impact on voice and creative behaviors.
Research Implications - Transformational leadership and transactional leadership are two separate and complementary types of leadership. Therefore, organizations should develop leaders that can flexibly use both styles to improve leadership effectiveness. Furthermore, the organization should pay more attention to employee job crafting, voice behavior, and creative behavior. Organizations or supervisors should appropriately grant employees work autonomy to respond to the rapidly changing external environment.
La representación de la epilepsia en el cine (2004-2021)
Authors: Mármol Julio
Published: June 2023

Introducción: Las personas con epilepsia han sido representadas en el cine como personajes marginales y trágicos. Sin embargo, esta tendencia parece estar cambiando. Objetivo: Analizar la representación cinematográfica de la epilepsia en todas las películas que hayan abordado esta enfermedad durante el periodo de tiempo comprendido entre 2004 y 2021. Método: Visionado y análisis de todas las películas que abordan la epilepsia, según IMDB, en el periodo de tiempo mencionado. Resultados: 1) El drama es el género cinematográfico de preferencia, con fuerte presencia de las películas biográficas 2) Estados Unidos continúa como el principal país en la muestra 3) La epilepsia ha dejado de ser, exclusivamente, un recurso narrativo y aparece con un elemento arbitrario, sin peso en la trama 4) Si en la muestra cinematográfica estudiada por Baxendale había dos hombres con epilepsia por cada mujer, en este análisis el porcentaje masculino decrece hasta un 57% frente a un 43% de películas en las que es una mujer quien sufre epilepsia. Conclusiones: La muestra revela cambios significativos respecto a la analizada por Baxendale, como el hallazgo de nuevas sensibilidades, la aparición de películas que tratan de concienciar al público sobre esta enfermedad y el incremento de personajes femeninos que sufren de epilepsia.

Published: June 2023

Introducción: A pesar del auge de la disciplina de la Comunicación y Salud, sigue habiendo nichos dentro de ella donde las contribuciones científicas son escasas. Sucede así con la comunicación en el ámbito de los Determinantes Sociales de la Salud (DSS), si bien falta por concretar el grado o proporción de esa escasez de la que habla la literatura. Objetivo: Superar afirmaciones intuitivas y medir la presencia de la temática comunicativa y mediática en las investigaciones de los principales autores sobre DSS. Metodología: Se realizó un análisis en las dos bases de datos científicas habitualmente utilizadas como referencia para la indexación y atribución de factor de impacto científico: Web of Science y Scopus. Resultados: Solo el 3% de los 679 manuscritos indexados en Scopus por los 10 autores que más han publicado sobre DSS hicieron alguna referencia a la temática comunicativa y/o mediática. Esta cifra fue el 5,2% de 384, en el caso de Web of Science. Conclusión: Se ratifica y se cuantifica la limitada presencia de la comunicación en los DSS. Se identifica, así mismo, a los autores que han abordado la temática con mayor frecuencia, con vistas a posteriores análisis cualitativos.

O silêncio que sobrevém à Cadeia Surda
Authors:   Universidade Estadual de Campinas, Barros Antônio Leandro Gomes de Souza
Published: June 2023

No século XVIII, Giambatistta Vico elaborou um novo modelo histórico epistemológico no estudo das obras de arte. Sua Ciência Nova é até hoje reconhecidamente inovadora pela investida em desfazer duas cismas: a da suposta irrelevância científica da arte, fosse como ingenuidade de um saber não racional fosse como mera diversão social e popular, ou ainda a cisma da sua suposta sabedoria esotérica, fosse como inalcançável mistério fosse por impossibilidade histórica de compreensão. Vico as desautoriza por considerá-las a ilegítima dupla face de um mesmo uso impróprio: a serventia transcendente da arte, resumida como de uma maneira ou de outra sempre a substituir alguma coisa em seu lugar (cópia, imitação…).

Published: June 2023

This research explores the development and influence of the Islamic revivalism movement at Hasanuddin University, South Sulawesi. Employing an in-depth case study, this study focuses on three student groups: Kesatuan Aksi Mahasiswa Muslim Indonesia (KAMMI), Gema Pembebasan (GEMAPEM), and the Salafi group within the Campus Da'wah Institute. The research found that these groups act as learning communities and active agents in shaping students' religious understanding and practices. The research also shows that these groups' persuasive and systematic methods are important in spreading their teachings and influence. While this research opens up a new understanding of this phenomenon, several limitations were identified, including the scope of the study being limited to one university and the lack of research on other factors that may be influential. This research contributes to a deeper understanding of the dynamics of the Islamic student movement and its influence on university students in Indonesia.
İmam Ebû Hanîfe’nin Menkıbevî Kişiliği Üzerine Bazı Mülahazalar
Authors: ÇAKIR Mustafa
Published: June 2023

Menkıbeler, geçmişte yaşamış din büyüklerinin ya da tarihe mâl olmuş meşhur şahsiyetlerin hayat hikâyelerini içeren anlatılardır. Tarihsel geçmişi İslâmiyet’ten önceki toplumlara uzanan menkıbelerin İslâmî literatürdeki ilk yazılı örneklerine hadis eserlerinde sahâbe-i kirâmın meziyetlerinden bahseden “menâkıb” bölümlerinde rastlanmaktadır. İlerleyen süreçte tarihte yaşamış din bilginleri, sûfîler ve önemli şahsiyetler hakkında da müstakil menâkıbnâmeler kaleme alınmaya başlanmıştır. İslâm tarihi içerisinde kendisine karşı sevgi, vefa ve bağlılığın bir sonucu olarak hakkında yoğun bir menâkıbnâme literatürü oluşan öncü imamlardan biri de Hanefî mezhebinin kurucu imamı olan İmam Ebû Hanîfe’dir. İmam Ebû Hanîfe’nin hacimli eserler oluşturan ilim mirasının yanında şahsiyeti, duruşu, zühdü, takvası ve ahlakî özellikleri bu tür müstakil çalışmaların konusu olmuştur. İmam Ebû Hanîfe’nin ilmî ve ahlakî kişiliğini resmeden bu edebiyatın hacmi, onun tarih boyunca Müslüman toplumlarda ne düzeyde ilgi odağı hâline geldiğini göstermektedir. Bununla birlikte menâkıbnâmelerde yer verilen birtakım rivayetlerde senet ve metin tenkidi bakımından yeterli hassasiyetin gösterilmemiş olması Müslüman toplumların İmam Ebû Hanîfe hakkındaki tasavvur ve algısına olumsuz etki edebilecek bir muhteva ortaya çıkarmıştır. Bu sebeple İmam Ebû Hanîfe’nin müdafaası ve faziletini ortaya koyma çabası kapsamında ileri sürülen bazı argümanların ilmî ve olgusal gerçeklik açısından sorgulanmaya muhtaç olduğu görülmektedir. Bu çalışmada, İmam Ebû Hanîfe hakkında kaleme alınan menâkıbnâme literatürü içerisinde esasen onun ilmî kişilik ve faziletini ortaya koymayı amaçlayan, bununla birlikte İslâm toplumunun bu öncü fakihi hakkında yanlış algı ve tasavvurlara sebep olabileceği düşünülen bazı isnat ve yakıştırmalar ilmî kriterler ışığında tahlile tabi tutulmaktadır.
SOURCE IDENTIFICATION METHODOLOGY IN RADIO MONITORING OBJECTS USING MULTI-MEANING
Authors: Ilnytskyi Аnatolii , Tsukanov Oleg
Published: June 2023

Background. With the constant development of radio-electronic equipment and telecommunication technologies and the appearance of new technical means of various purposes, including dual meaning, which already have and operate with new “non-traditional” information features. The specified circumstances require the improvement of their radio monitoring and countermeasure systems, from the point of view of the development of highly effective intelligent systems that ensure the collection, processing, accumulation and use of the received monitoring information for decision-making on a real-time scale.

Objective. Increasing the effectiveness of radio monitoring of radio radiation sources is carried out by decomposing their informational features into static and dynamic ones with further formalization of the observation and decision-making process.

Methods. The decision on whether the source of radio radiation belongs to one or another class is made on the basis of a preliminary calculation of information feature estimates for all possible sets of features and the use of multi-valued logic functions to make a decision. The preliminary calculation makes it possible to increase the speed of the algorithm and make a decision about whether the object of recognition belongs to one or another class by calculating the value of only one function, and recalculating the estimates of static and dynamic information features only when the descriptions of classes of radio radiation sources are changed.

Results. The proposed technique makes it possible to significantly expand the classes of classes of sources and objects of radio monitoring and will ensure an increase in the speed and reliability and efficiency of the recognition process as a whole.

Conclusions. Deciding whether a source of radio radiation belongs to one or another class through the use of multi-valued logic functions allows increasing the efficiency of the radio monitoring system and significantly expand the class of monitoring sources.

Published: June 2023

The work is devoted to studying SARS-CoV-2-associated pneumonia and the investigating of the main indicators that lead to the patients’ mortality. Using the good-known parameters that are routinely embraced in clinical practice, we obtained new functional dependencies based on an accessible and understandable decision tree and ML ensemble of classifiers models that would allow the physician to determine the prognosis in a few minutes and, accordingly, to understand the need for treatment adjustment, transfer of the patient to the emergency department. The accuracy of the resulting ensemble of models fitted on actual hospital patient data was in the range of 0.88–0.91 for different metrics. Creating a data collection system with further training of classifiers will dynamically increase the forecast’s accuracy and automate the doctor’s decision-making process.
A modification of Petri nets with anticipation on a position
Authors: Statkevych Vitalii
Published: June 2023

We propose a modification of Petri nets with strong anticipation on a position. The extension modifies a transition rule by adding a new term that contains an integer function of the new marking in the position. The differences from classic Petri nets are found; for example, the set of markings that are reachable from a current marking by firing the enabled transition can either be empty or contain more than one marking. We consider the construction of a reachability graph and a coverability tree. We give the conditions for the existence of the coverability tree and propose the algorithm for constructing the coverability tree that generalizes the well-known classic algorithm. The main ideas and constructions are illustrated in the examples.
Paving the Way for Memory Enhancement: Development and Examination of a Neurofeedback System Targeting the Medial Temporal Lobe
Authors: Koizumi Koji , Kunii Naoto , Ueda Kazutaka , Nagata Keisuke , Fujitani Shigeta , Shimada Seijiro , Nakao Masayuki
Published: June 2023

Neurofeedback (NF) shows promise in enhancing memory, but its application to the medial temporal lobe (MTL) still needs to be studied. Therefore, we aimed to develop an NF system for the memory function of the MTL and examine neural activity changes, and memory task score changes through NF training. We created a memory NF system using intracranial electrodes to acquire and visualise the neural activity of the MTL during memory encoding. Twenty trials of a tug-of-war game per session were employed for NF and designed to control neural activity bidirectionally (Up/Down condition). NF training was conducted with three patients with intractable epilepsy, and we observed an increasing difference in NF signal between conditions (Up−Down) as NF training progressed. Similarities and negative correlation tendencies between the transition of neural activity and the transition of memory function were also observed. Our findings demonstrate NF's potential to modulate MTL activity and memory encoding. Future research needs further improvements to the NF system to validate its effects on memory functions. Nonetheless, this study represents a crucial step in understanding NF's application to memory and provides valuable insights for developing more efficient memory enhancement strategies.
Comparative Analysis of Evolutionary Techniques for Economical Load Dispatch in a 6-Unit Thermal Power System
Authors: KHOBARAGADE TEJASWITA , Chaturvedi Dr. K.T. Chaturvedi
Published: June 2023

The economical load dispatch problem is a critical concern in thermal power systems to ensure cost-effective operation. This paper conducts a comparative analysis between the Social Spider Algorithm (SSA) and Particle Swarm Optimization (PSO) for economical load dispatch in a 6-unit thermal power system with the integration of 11,000 plug-in electric vehicles (PEVs). Both SSA and PSO are population-based optimization techniques designed to minimize the overall fuel cost while satisfying the load demand by determining the optimal power output of each unit. SSA emulates the social behavior of spiders, while PSO simulates the collective intelligence of a swarm of particles. Performance evaluation of the algorithms considers power system data, such as unit fuel costs, minimum and maximum loads, and total load demand. The objective is to minimize fuel cost while meeting the load demand. Comparative analysis of SSA and PSO includes convergence speed, solution quality, and computational efficiency. Experimental results indicate that SSA outperforms PSO in achieving a more optimal and economical load dispatch solution for the 6-unit thermal power system. SSA demonstrates faster convergence and provides superior-quality solutions compared to PSO. This paper contributes to the field by highlighting SSA's effectiveness in achieving cost-efficient operation of thermal power systems. The findings suggest that SSA holds promise as an optimization technique for similar power system optimization problems, enhancing overall operational efficiency and reducing costs for thermal power plants.
The Reduction of Mitochondrial Membrane Potential in Aging: The Role of the Mitochondria Permeability Transition Pore
Authors: Rottenberg Hagai
Published: June 2023

It is widely reported that the mitochondrial membrane potential, ∆Ψm, is reduced in aging animals. It was recently suggested that the lower ∆Ψm in aged animals modulate mitochondrial bioenergetics and that this effect is a major cause of aging since artificially increased ∆Ψm in C. elegans increased lifespan. Here I review, critically, studies that reported reduction of ∆Ψm in aged animals, including worms, and conclude that many of these observations are best interpreted as evidence that the fraction of depolarized mitochondria is increased in aged cells because of the enhanced activation of the mitochondrial Permeability Transition Pore, mPTP. Activation of the voltage-gated mPTP depolarizes the mitochondria, inhibits oxidative phosphorylation, releases large amounts of calcium and mROS, and depletes cellular NAD+, thus accelerating degenerative diseases and aging. Since the inhibition of mPTP was shown to restore ∆Ψm and retard aging, the reported lifespan extension by artificially generated ∆Ψm in C. elegans is best explained by inhibition of the voltage-gated mPTP. Similarly, the reported activation of the mitochondrial Unfolded Protein Response by reduction of ∆Ψm, and the reported preservation of ∆Ψm in dietary restriction treatment in C. elegans are best explained as a resulting from activation or inhibition of the voltage-gated mPTP, respectively.
Biographical reinvention through additive and subtractive strategies: the experience of men living with HIV in Indonesia
Authors: Fauk Nelsensius Klau , Mwanri Lillian , Gesesew Hailay Abrha , Ward Paul Russell
Published: June 2023

HIV diagnosis and management have often caused disruptions to the everyday life and imagined futures of people living with HIV, both at individual and social levels. This has been conceptualised, in a rather dystopian way, as ‘biographical disruption’. This paper attempts to re-cast data from interviews with 40 men living with HIV (MLHIV) in Yogyakarta and Belu, Indonesia, in a slightly more positive light. Our analysis uses the concepts of additive and subtractive resilience strategies and we show how, rather than having a purely disrupted biography, participants talked about their experiences of ‘biographical reinvention'. Study participants were recruited using the snowball sampling technique, starting from two HIV clinics in the settings. Data were collected using one-on-one in-depth interviews, and a qualitative framework analysis was used to guide step-by-step data analysis. The findings showed that despite the disruptions in their everyday life (i.e., mental health condition, work, activities, social relationships, etc.) following the HIV diagnosis and management, MLHIV in our study managed to utilise their internal assets or traits (i.e., hope, optimism, resilience) and mobilised external resources (i.e., support from families, friends and healthcare professionals) to cope with the disruptions. An interweaving of these internal assets and external resources enabled them to take on new activities and roles (additive resilience strategies) and give up health compromising behaviours (subtractive resilience strategies). These were effective for most MLHIV in our study not only to cope with the HIV repercussions and improve their physical and mental health conditions, but to think or work on a ‘reinvented’ biography which encompassed resilience, hope and optimism for better health, life and future. The findings indicate the need for HIV interventions and healthcare systems that provide appropriate support for the development and maintenance of internal assets of PLHIV to enable them to cope with the repercussions of HIV and work on a ‘reinvented’ biography.
SU(3) Brachistochrone and the Isotropic Oscillator
Authors: Morrison Peter
Published: June 2023

This paper discusses two major applications of SU(3) theory, the first being the question of quantum brachistochrones and problems in time optimal control theory, the second being the use of spherical tensor decompositions of the special functions which are associated to SU(3) via the isotropic oscillator. We discuss the derivation of the quantum brachistochrone problem more generally from the perspective of von Neumann equations and matrix mechanics, arriving at an equivalent formulation to the Lagrangian method. Discussion is given to the application of such advanced methods in quantum computation, and some future directions that may be amenable to a similar sort of an
Design and Performance Analysis of Microwave Photonic Spectral Domain Filters Using Optical Microcombs
Authors: Moss David
Published: June 2023

Microwave transversal filters, which are implemented based on the transversal filter structure in digital signal processing, offer a high reconfigurability for achieving a variety of signal processing functions without changing hardware. When implemented using microwave photonic (MWP) technologies, also known as MWP transversal filters, they provide competitive advantages over their electrical counterparts, such as low loss, large operation bandwidth, and strong immunity to electromagnetic interference. Recent advances in high-performance optical microcombs provide compact and powerful multi-wavelength sources for MWP transversal filters that require a larger number of wavelength channels to achieve high performance, allowing for the demonstration of a diverse range of filter functions with improved performance and new features. Here, we present a comprehensive performance analysis for microcomb-based MWP spectral filters based on the transversal filter approach. First, we investigate the theoretical limitations in the filter spectral response induced by finite tap numbers. Next, we analyze the distortions in the filter spectral response resulting from experimental error sources. Finally, we assess the influence of input signal’s bandwidth on the filtering errors. These results provide a valuable guide for the design and optimization of microcomb-based MWP transversal filters for a variety of applications.

Background: Diabetes mellitus is one of the most common endocrinopathies, estimated to affect about 5.4% of the world's population around 2025. It is thought that nearly a third of diabetic patients have some type of skin condition. Frequently, the cutaneous effects of this heterogeneous syndrome are accurately detected late in the progressive form of the disease. Methods: Skin fragments were harvested from adult white Wistar rats of both sexes, with the weight of 200 g, 12 weeks after streptozotocin diabetes was induced. In parallel with histopathological diagnosis by using hematoxylin and eosine staining, samples were processed by transmission electron microscopy technique and examined with a Philips CM100 microscope. Results: In the apparently macroscopically unchanged tegument, photon microscopy revealed both progressive thinning of the epidermis in the early stages of diabetes and a significant process of fibrosis and collagen hyalinization in the dermis. In addition, in the early stages, the electron microscopic study provided ultrastructural details characteristic of a senescent phenotype with reduced cell proliferation. Conclusions: The morphological changes in the skin may be the first signs of disruption of carbohydrate metabolism and in the case of established diabetes may reflect its progression and the efficacy of therapy.

The aim of this article is to present a methodology of determining of the individual values of the parameters of four-element equivalent circuits for insulation with through conductivity. Methodology. The proposed method consists in the fact that at a time interval of more than 10 s, when the charge indicator no longer contributes to the leakage current, three points t1, t2 and t3 are selected, such that t2 – t1 = t3 – t2. To be able to determine the absorption coefficient R60/R15, it is recommended to take t1 = 15 s, t2 = 37.5 s and t3 = 60 s. At the same time, by subtracting I(t2) – I(t1) and I(t3) – I(t2), the constant component of the absorption curve is excluded and it becomes possible to determine the individual values of the parameters of the generalized equivalent circuit of insulation, additionally using its conductivity in operator form. Results. As calculations show, the correct determination of the parameters of insulation equivalent circuit according to the proposed method is possible only with a certain ratio of these parameters. The charge time of the geometric capacitance Cg(R0+Rd), where R0 and Rd are the resistance that forms the charging exponent, and the resistance of the sensor, should be within 0.2 s <Cg(R0+Rd)<1 s, the time constant CaRa, where Ca and Ra are the capacitance and resistance of the absorption chain, should be more than 3 s, the product of CgRl, where Rl is the leakage resistance, more 0.5 s, the leakage resistance Rl is less than the absorption resistance Ra. Checking the methodology on a model example gives the values of the parameters of the insulation equivalent circuit that match the specified ones with high accuracy. Practical value. The use of individual values of the parameters of insulation equivalent circuits when applying absorption diagnostic methods with considering the time values and dimensional factors, allow to calculate all currently used diagnostic parameters, to determine the conditions of certain insulation types, as well as in more detail, in comparison with the existing approach, to assess the technical condition of the insulation and the reasons of its changes.

Published: June 2023

Introduction. An analysis of incidents linked to power units’ emergency disconnecting from network as a result of turbogenerators’ malfunction on the NPP of Ukraine is conducted. It is identified, that the reason of the majority of incidents is an insufficient reliability of the stator winding’s direct cooling system. Problem. The most problematic point in winding for today is the frontal parts, where, while cooling is reduced, there are not only thermal, but also thermomechanical loadings on an insulation appearing. The level of these loading depends on structural design of frontal parts and a character of violation of coolant agent circulation in a bar. In some cases they can exceed limit values. The spread and the quality of research on this issue for today are insufficient. Goal. The aim of the completed research is to determine the thermomechanical loading of insulation of stator winding bar in a powerful turbogenerator with a direct liquid cooling under condition when coolant circulation is malfunctioned. Methodology. A complex mathematical model of thermomechanical processes in an insulation of stator winding bar of a powerful turbogenerator is developed. It takes into account the real geometry of the winding bar, variable thermal loading of core elements in radial and axial directions, as well as ways of fixation of slot and frontal winding parts. Studies of thermomechanical processes in an insulation of stator winding bar of turbogenerator are conducted. Results. Values of mechanical displacement and stress for the different modes of malfunction are obtained. Areas of bar, where mechanical loading may exceed the boundaries of mechanical durability of material of insulation of stator winding are identified. With decline of coolant liquid consumption the radial displacement and stress in the winding insulation bar in the area, where the bar exits from the slot are increasing along with that the values of radial stress of insulation of the winding bar in places of frontal parts’ fixation exceed limit values. Practical significance. The offered mathematical models allow to realize calculation experiments and can be used in practice for development and validation of diagnostic systems, analysis, design and investigation of emergency situations during exploitation of turbogenerators on power stations of Ukraine.

The creation and sharing of videos with the aim of promoting the use of digitally interactive multimedia, such as music, graphics, and video between devices for both social networking applications and everyday tasks have increased significantly along with the use of digital communication devices in recent years. In the digital sphere, forgery techniques and motivations have substantially evolved. Before, methods of video editing were applied to improve digital data. With the rise in popularity of low-cost, user-friendly video editing software, there are a number of downsides and risks related to these editing methods. In order to produce altered or fraudulent videos, additional footage is mixed, edited, or synthesized. Existing method uses methods that detect forgery in videos with simply static backgrounds only. Proposed systems uses a deep learning strategy that incorporates transfer learning utilizing VGG16 and Customized CNN layers to categorize real time videos as tampered or authentic .With the aid of deep neural networks, the suggested method may identify forgery in films with both static and moving backgrounds. The experimental findings show that the suggested strategy is over 99.9% more accurate and effective than existing methods also it provides trustworthy results with low computing cost and strong detection performance.

Published: June 2023

Tyrosine kinase 2 (TYK2) is a member of the Janus kinase (JAK) family, which plays an important part in signal transduction and regulation of the immune system. To minimize the safety concerns and improve the therapeutic effect against autoimmune diseases, we developed a small molecule inhibitor (QL-1200186) targeting the pseudokinase domain of TYK2 protein (JH2). The binding sites of QL-1200186 were predicted and screened by molecular docking. The inhibitory effects of the downstream signaling pathways and transcriptional activators of TYK2 were reflected in cell lines and human peripheral-blood cells. Pharmacokinetics and pharmacodynamics were verified in mice. QL-1200186 showed highly affinity to TYK2 JH2 and had no apparent selectivity for the TYK2 and JAK homologous kinase domains (JH1); these effects were manifested in assays based on biochemical binding, signaling pathway transduction (JAK1/2/3) and off-target effects. We revealed that currently available drugs, such as BMS-986165 and NDI-034858, were the most likely candidates for TYK2 inhibitors, and found that QL-1200186 was functionally comparable to and selectively superior to both agents in vitro. QL-1200186 showed excellent exposure, high bioavailability and afforded low clearance rates in mice. Oral administration of QL-1200186 dose-dependently inhibited interferon-γ production in interleukin-12-driven responses and ameliorated skin lesions significantly in a mouse model of psoriasis, respectively. These findings suggest that QL-1200186 is a highly selective and potent inhibitor of TYK2. QL-1200186 could be developed as a drug for the treatment of psoriasis or other autoimmune diseases.
