Synthetic dual image generation for reduction of labeling efforts in semantic segmentation of micrographs with a customized metric function
Authors: Volman Stern Matias Oscar , Hohs Dominic , Jansche Andreas , Bernthaler Timo , Schneider Gerhard
Published: December 2024

Training of semantic segmentation models for material analysis requires micrographs as the inputs and their corresponding masks. In this scenario, it is quite unlikely that perfect masks will be drawn, especially at the edges of objects, and sometimes the amount of data that can be obtained is small, since only a few samples are available. These aspects make it very problematic to train a robust model. Therefore, we demonstrate in this work an easy-to-apply workflow for the improvement of semantic segmentation models of micrographs through the generation of synthetic microstructural images in conjunction with masks. The workflow only requires joining a few micrographs with their respective masks to create the input for a Vector Quantised-Variational AutoEncoder (VQ-VAE) model that includes an embedding space, which is trained such that a generative model (PixelCNN) learns the distribution of each input, transformed into discrete codes, and can be used to sample new codes. The latter will eventually be decoded by VQ-VAE to generate images alongside corresponding masks for semantic segmentation. To evaluate the quality of the generated synthetic data, we have trained U-Net models with different amounts of these synthetic data in conjunction with real data. These models were then evaluated using real microscopic images only. Additionally, we introduce a customized metric derived from the mean Intersection over Union (mIoU) that excludes the classes that are not part of the ground-truth mask when calculating the mIoU of all the classes. The proposed metric prevents a few falsely predicted pixels from greatly reducing the value of the mIoU. With the implemented workflow, we were able to achieve a time reduction in sample preparation and acquisition, as well as in image processing and labeling tasks. The idea behind this work is that the approach could be generalized to various types of image data such that it serves as a user-friendly solution for training models with a smaller number of real images.
Mechanical properties of laser welded similar and dissimilar steel joints of TBF1050 and DP1000 steel sheets
Authors: Ozturk Yilmaz Imren , Aydın Hakan
Published: December 2024

TBF1050 and DP1000 sheets in different thicknesses were laser welded in butt configuration. The welds were performed both similar and dissimilar. Welding speed was changed between 40 and 120 mm/min. Characterization of the welds was carried out by means of microstructure, microhardness, tensile properties and fractography. The grain structure in heat affected zone (HAZ) on DP1000 side was a relatively coarser than that on TBF1050 side. The highest hardness was obtained in fusion zone. The presence of TBF1050 steel in the joint increased the hardness of the fusion zone. On both steel sides, the hardness in a narrow zone between the tempered zone and the base metal decreased below the hardness of the base metals (softening zone). The softening zone hardness on TBF1050 side was relatively higher than that on DP1000 side. The tensile strengths of each laser welded joint, except for DP1000 similar joint, were all higher than 1,000 MPa. When the fractures occurred on the TBF1050 side, the tensile strength was higher. Whether the TBF1050 steel sheet was galvanized or not did not cause any significant effect on the microstructure and the mechanical properties of the joints. The joint fractured from HAZ had a completely brittle fracture behavior.

O Laboratório como Organização?
Authors: Leandro Rezende Daniela , Luiz Alves Mourão Victor , Horácio Barbosa Jéssica
Published: December 2024

O objetivo do artigo é refletir sobre o laboratório como organização à luz da teoria do ator-rede e dos estudos críticos em Administração. Essa aproximação permite desnaturalizar as organizações como dadas, trazendo à tona os complexos processos pelos quais o laboratório toma forma, a partir do controle de incertezas e instabilidades, de articulação entre diferentes atores e das estratégias voltadas à transformação de elementos dispersos em uma lógica coerente, passível de ser apresentada como conhecimento científico. A investigação teve como objetivo empírico uma universidade pública federal localizada em Minas Gerais, em que pesquisas com/sobre cannabis são desenvolvidas na área da agronomia. Foram realizadas entrevistas semiestruturadas, além e observação participante em laboratórios de pesquisa. Como principais resultados, argumentamos que a pesquisa permitiu desnaturalizar as organizações como dados estáveis e perenes, indicando as múltiplas estratégias de tradução/translação voltadas à estabilização de uma rede de atores que envolve, além de seres humanos (pesquisadores/as) com interesses, status e formações profissionais diferentes e até conflitantes, atores não humanos, como as plantas de cannabis, os equipamentos, estruturas físicas dos laboratórios analisados, que terminam por constranger a instrumentalidade suposta/idealmente presente em investigações científicas, voltadas ao controle do meio/contexto/aleatoriedade, de forma a produzir conclusões válidas e amplamente aceitas. Além disso, a pesquisa com/sobre cannabis ilumina aspectos éticos e políticos relacionados à criminalização da planta, que dificulta o desenvolvimento de pesquisas sobre o tema e requer o engajamento de diferentes atores para sua viabilização, muitos deles não cientistas, como aqueles vinculados, por exemplo, ao poder judiciário e ao mercado.

Published: December 2024

Objective:

This study was aimed at investigating the viral diversity associated with marine organisms in the South China Sea, to improve understanding of the region’s viral ecosystems. Viruses profoundly influence aquatic ecosystems, by affecting marine biogeochemical cycles and posing threats to marine organisms. Nonetheless, a comprehensive study of marine organisms’ viral diversity in the South China Sea remains lacking.

Methods:

We collected gill and viscera tissue samples from three marine phyla (Chordata, Arthropoda, and Mollusca) along the South China Sea coast. High-throughput sequencing and bioinformatics analyses were conducted to identify and characterize viral communities within these samples, with a focus on both viral composition and potential zoonotic threats.

Results:

We observed distinct viral composition patterns across tissues and phyla, notably involving Adintoviridae and viruses within the Herpesviridae and Dicistroviridae. The presence of zoonotic viruses in economically important aquatic organisms suggests potential risks.

Conclusion:

This study contributes to broader understanding of viral diversity, by suggesting potential epidemic causes and illustrating genetic relationships among viruses associated with marine organisms. By extending the virus distribution map for this region, our findings underscore the need to consider the viral microenvironments surrounding marine species, and their implications for marine and human health.
Les transformations de l’espace et du modèle hybride du travail par les aires ouvertes : les effets du télétravail sur la conciliation entre les vies personnelle et professionnelle
Authors: Alla Tawfiq , Roume Stéphane F. , Tremblay Diane-Gabrielle
Published: December 2024

Après la période de confinement, les aires ouvertes et le télétravail ont progressé. Nous avons étudié six organisations (publiques, privées et en économie sociale) au Québec et effectué des entretiens semi-dirigés (n=66) de février à octobre 2023. Nous avons observé les adaptations dans l’articulation entre le retour progressif au sein de l’aire ouverte et le télétravail à domicile, une flexibilité du temps de travail et enfin, une meilleure conciliation entre les vies personnelle et professionnelle. Cette étude permet d’actualiser des résultats concernant les aires ouvertes, avec l’expansion du télétravail, mettant ainsi en évidence que le lieu de travail s’est significativement déplacé vers le domicile des employés. Cela a engendré une nouvelle organisation horaire et spatiale des familles : la famille est donc une institution qui se voit évoluer en conséquence. Le lieu de travail mis à disposition devient quant à lui, en grande partie, un lieu de socialisation.
Effets potentiels de l’intelligence émotionnelle des gestionnaires sur les subordonnés au travail : une recension systématique de la littérature
Authors: Lalonde Francoeur David , Paquet Maxime
Published: December 2024

Les transformations successives des environnements de travail, notamment sur le plan technologique, s’avèrent émotionnellement exigeantes et sont susceptibles d’affecter les attitudes et la performance des travailleurs. Dans ce contexte, l’intelligence émotionnelle (IÉ) des gestionnaires a été soulevée comme une ressource substantielle pour soutenir et influencer leurs subordonnés. Cependant, étant donné la large étendue de résultats empiriques sur les effets potentiels de l’intelligence émotionnelle des gestionnaires (IÉG) sur les subordonnés au travail et la variété d’instruments de mesure de l’IÉ, la compréhension de ces effets potentiels dans la littérature demeure un défi à ce jour. Cette recension systématique, réalisée à partir du protocole PRISMA 2020, présente une synthèse qualitative des effets potentiels de l’IÉG sur les subordonnés et des processus impliqués, et ce, en classant les résultats à partir des trois courants de l’IÉ. À la suite du processus de sélection et de l’évaluation de la qualité des études, un total de 56 études (1990-2023) a été retenu. Les résultats révèlent que l’IÉG a un effet potentiel significatif sur la performance des subordonnés (performance individuelle; performance et efficacité d’équipe; créativité et comportements d’innovation et comportements de citoyenneté organisationnelle) dans approximativement 85 % des études recensées et sur les attitudes (satisfaction individuelle et de groupe au travail; engagement et épuisement professionnel), les affects et les autres variables liées aux subordonnés dans approximativement 92 % des études. Le présent article illustre de manière complète et accessible les effets potentiels de l’IÉG sur les subordonnés et offre aux chercheurs un point de départ pour bâtir leur modèle d’étude.
Promouvoir l’adoption de l’IA dans les milieux d’emploi par l’entremise de l’explicabilité et de la confiance : une étude empirique
Authors: Masciotra Viviane , Boudrias Jean-Sébastien
Published: December 2024

L’intelligence artificielle (IA) est associée à plusieurs bénéfices pour les travailleurs et les organisations. Toutefois, ses capacités inédites sont propices à engendrer chez les humains de la crainte pour la pérennité de leur emploi, et de la réticence à utiliser l’IA. Dans la présente étude, nous explorons le rôle de la confiance envers l’utilisation de l’IA chez les travailleurs, ainsi que la capacité de l’explicabilité de l’algorithme à promouvoir la confiance. À cet effet, un devis expérimental à répartition aléatoire a été utilisé. Les résultats révèlent que la confiance favorise l’intention d’utiliser l’IA, mais que l’explicabilité ne contribue pas au développement de la confiance. De plus, l’explicabilité a eu un effet inattendu délétère sur l’intention d’utiliser l’IA.
Pratiques EDI et transformations organisationnelles en économie sociale et action communautaire : le rôle d’une méta-organisation en contexte québécois
Authors: Séguin Michaël , Morin Lucie , Arcand Sébastien
Published: December 2024

La gestion de l’équité, de la diversité et de l’inclusion (EDI) dans le secteur privé se réduit souvent à son « comment », à savoir un plan d’action accompagné d’indicateurs de performance. Alors que se multiplient les « recettes », la question du « pourquoi » et de l’étendue des transformations organisationnelles que requière un tel virage est beaucoup moins abordée. Or, s’il est bien un secteur qui se soucie foncièrement du « pourquoi », c’est celui de l’économie sociale et de l’action communautaire, justement parce qu’il fait de la transformation sociale une préoccupation centrale, y compris en agissant par, pour et avec ses membres. À partir du cas du Comité sectoriel de main-d’oeuvre de l’économie sociale et de l’action communautaire (CSMO-ÉSAC), lequel représente 18 643 regroupements et organisations, cet article s’attarde tant aux transformations du secteur qu’à celles du CSMO-ÉSAC en tant que méta-organisation. Croisant la théorie néo-institutionnelle et le concept de méta-organisation, notre analyse, fondée sur des documents et des entretiens, démontre que le CSMO-ÉSAC a entrepris il y a une quinzaine d’années une démarche de transformation organisationnelle en intégrant le paradigme EDI. Cette transformation issue d’une pression normative provenant aussi bien de son personnel, de ses organisations membres que de son principal bailleur de fonds consiste principalement en une réinterprétation et un approfondissement de sa mission à la lumière de l’EDI. Ceci a notamment engendré une dynamique d’apprentissage en continu en matière de diversité – dans la veine des organisations apprenantes – que le CSMO-ÉSAC tente de diffuser, non sans difficulté, dans son secteur.

Published: December 2024

Les applications de l’intelligence artificielle (IA) sont susceptibles de transformer le travail de professionnels(les) (soignants, juristes, enseignants, travailleurs sociaux, etc.). Cette étude de portée (scoping review) s’inscrit dans une collaboration entre les milieux syndicaux et de la recherche afin d’identifier les applications, usages et enjeux de l’IA qui sont documentés en lien avec le travail de professionnels(les). Les résultats montrent que l'IA est très présente dans des secteurs comme la santé, l’administration, le droit et l’enseignement. Ses finalités sont multiples : depuis l’archivage de données jusqu’à la prise de décision en passant par le traitement de textes, les interactions, la reconnaissance ou la simulation. Elle pourrait se développer dans de nombreux métiers et créer des enjeux transversaux majeurs, en particulier autour des compétences, des emplois, de l’éthique et du fonctionnement des organisations. Des enjeux plus spécifiques à chaque métier sont aussi identifiables. Ces résultats permettent de proposer une discussion pluridisciplinaire de ces enjeux en traitant de l’éthique dans la problématique du consentement à l’IA, de la dualité technologique de l’IA, du rôle d’un syndicat par rapport à l’IA et du défi informatique de l’explicabilité de l’IA.
Fausses promesses et stupidité organisationnelle : pourquoi l’IA n’est pas synonyme de performance
Authors: Desjardins Guillaume , Gould Anthony
Published: December 2024

Depuis l’apparition de ChatGPT, le terme intelligence artificielle (IA) semble devenir une mode dans laquelle plusieurs champs d’expertise doivent renégocier les paradigmes établis. Dans le contexte du travail, une littérature grandissante prédit des transformations majeures dans l’organisation du travail résultant des emplois devenus obsolètes par l’utilisation de l’IA. Cet essai provocateur ira à l’encontre de ce courant. Afin d’appuyer l’argumentation, les auteurs emploieront le concept de la stupidité organisationnelle afin de démontrer comment le côté irrationnel voire stupide des entreprises surpassera la rationalité efficiente promise par l’IA. Enfin, des implications pratiques seront proposées pour les décideurs en organisation.
The Dimensionality of Neural Coding for Cognitive Control Is Gradually Transformed within the Lateral Prefrontal Cortex
Authors: Chiou Rocco , Duncan John , Jefferies Elizabeth , Lambon Ralph Matthew A.
Published: December 2024

Cognitive control relies on neural representations that are inherently high-dimensional and distributed across multiple subregions in the prefrontal cortex (PFC). Traditional approaches tackle prefrontal representation by reducing it into a unidimensional measure (univariate amplitude) or using it to distinguish a limited number of alternatives (pattern classification). In contrast, representational similarity analysis (RSA) enables flexibly formulating various hypotheses about informational contents underlying the neural codes, explicitly comparing hypotheses, and examining the representational alignment between brain regions. Here, we used a multifaceted paradigm wherein the difficulty of cognitive control was manipulated separately for five cognitive tasks. We used RSA to unveil representational contents, measure the representational alignment between regions, and quantify representational generality versus specificity. We found a graded transition in the lateral PFC: The dorsocaudal PFC was tuned to task difficulty (indexed by reaction times), preferentially connected with the parietal cortex, and representationally generalizable across domains. The ventrorostral PFC was tuned to the abstract structure of tasks, preferentially connected with the temporal cortex, and representationally specific. The middle PFC (interposed between the dorsocaudal and ventrorostral PFC) was tuned to individual task sets and ranked in the middle in terms of connectivity and generalizability. Furthermore, whether a region was dimensionally rich or sparse covaried with its functional profile: Low dimensionality (only gist) in the dorsocaudal PFC dovetailed with better generality, whereas high dimensionality (gist plus details) in the ventrorostral PFC corresponded with better ability to encode subtleties. Our findings, collectively, demonstrate how cognitive control is decomposed into distinct facets that transition steadily along prefrontal subregions.
Beyond Exceptionalism: The Washington Conservatory of Music and the Education of Black Classical Musicians, 1903–60
Authors: Epstein Louis K. , Nagel-Frazel Maeve
Published: December 2024

Operating in Washington, DC from 1903 to 1960, the Washington Conservatory of Music was the first conservatory established by and for Black Americans in the United States. In this article we demonstrate the significant, continuing impact of the Washington Conservatory of Music through a study of the lives and contributions of the conservatory’s first thirty graduates, from the inaugural classes of 1910 through 1914. As teachers, performers, composers, activists, and leaders, the graduates of the Washington Conservatory were cornerstones of musical communities across the United States. Graduates of the Washington Conservatory rarely achieved fame as concert artists, but their lack of fame ultimately says less about the extent of their accomplishments than it says about longstanding silences in music historiography that privileges composers and performers over educators and church musicians. Drawing on physical and digitized primary sources including newspapers, city directories, census records, and extensive archival material, we further the critical historical recovery undertaken by Doris McGinty, Sarah Schmalenberger, Maud Cuney-Hare, and Eileen Southern that answers basic—but frustratingly elusive—questions about a relatively quotidian matter: who did what in Black musical communities. We argue that Washington Conservatory alumni were not only anchors in musical networks that extend through the present but representative figures who built lasting institutions and who exemplify the ubiquity of Black classical musicianship through American music history.
Heterogeneous ensemble classifier in computer systems for medical diagnostics
Authors: Povoroznyuk Anatoly I. , Povoroznyuk Oksana A. , Filatova Anna E.
Published: December 2024

The work is dedicated to the solution of an important scientific and technical problem: building a diagnostic decision-support
system in medicine. The foundation of this system is a model developed as a heterogeneous ensemble classifier, which implements
two primary approaches to formulating a diagnostic conclusion through basic models. The first of these approaches is probabilistic. It
is based on the analysis of a training sample of patients with a confirmed diagnosis, which enables estimation of the probability of the
presence of a particular disease based on available data. The second approach is expert-based, relying on expert information about
the structure of symptom complexes that characterize each individual disease. It is important to note that both of these approaches
address the same problem from different perspectives, and their combined use holds great promise for developing effective
diagnostic systems. The purpose of this study is to synthesize a heterogeneous ensemble classifier that integrates both expert and
probabilistic components into the diagnostic process. An analysis of various diagnostic methods used by doctors in alignment with
the current requirements of evidence-based medicine was carried out as part of the study. Methods of constructing diagnostic
decision rules in medical decision-support systems were also considered. Based on these studies, a mathematical model of a
heterogeneous ensemble classifier was developed, with the choice of its constituent parts being justified. Widely used classification
methods were selected as the probabilistic component in this system, particularly the standard comparison method, the k-nearest
neighbors method, and the potential functions method. Expert knowledge concerning the structure of symptom complexes is
formalized by expressing the symptom complexes of each disease in the form of numerical intervals. In this framework, linguistic
variables are used, which can indicate “below the norm”, “norm”, or “above the norm”. Various strategies for aggregating different
types of basic models within the heterogeneous ensemble classifier are reviewed. This approach preserves the advantages of each
method and enhances the overall classification accuracy. Requirements for the developed system's functionality were formulated,
design tools and the main development platform (Java) were defined, and the database management system (MySQL). The decisionsupport system was designed, and a comprehensive evaluation of the developed system was conducted on real medical data. The
results of these tests confirmed the effectiveness of the system.
Software tools for organizing cloud computing in psychophysiological research based on eye-tracking data

Published: December 2024

The architecture and web version of the software complex have been developed, which significantly expands the diagnostic
capabilities of model-oriented information technologies for the assessment of the neurophysiological state. The complex provides
cross-platform cloud computing, increases the productivity and efficiency of scientific research, using methods of non-parametric
identification of the oculomotor system based on eye-tracking data, which is achieved thanks to a new concept of cloud computing
organization. Cloud computing technology has been further developed thanks to the proposed concept that combines the principles of
PaaS (Platform as a Service) and SaaS (Software as a Service). The key feature of the complex is the interface builder and the code
translation module, which provide flexibility and convenience of working with the complex, allowing you to configure interface
elements and connect them with script-code in different languages. Automatic replacement of values in script-code simplifies the
adaptation of the complex to various tasks, making it accessible to users with any skill level, which is especially valuable for science
and education. In addition, the important feature of this software complex is its undemanding hardware on the client side thanks to
the use of cloud computing, and its modular structure, which allows it to be easily scaled. Compared to other similar services, the
complex has several advantages: it provides effective work in research and educational areas, supports several programming
languages for improving algorithms, and also allows the use of ready-made identification methods through specially developed GUI
interfaces. In addition, it offers social capabilities and a high level of abstraction that optimizes the research process.
Ambiguities and their emergence conditions in self-testing of multiprocessor systems
Authors: Romankevich Vitaliy A. , Morozov Kostiantyn V. , Romankevich Oleksii V. , Zacharioudakis Lefteris
Published: December 2024

The article addresses the issue of organizing self-testing in multiprocessor systems. It examines cases where the state of certain
processors (functional or faulty) remains ambiguous after executing a specific set of mutual processor tests. Determining the state of
such processors requires additional capabilities, such as extra connections between processors. Ambiguity most often arises when the
number of processors testing a given processor is less than the allowable number of faults. The study focuses on multiprocessor
systems whose diagnostic graphs can be represented as circulant graphs, particularly graphs with two incoming and two outgoing
edges. This relates to solving the problem of minimizing the number of mutual tests among system processors (each processor is tested
by only two others). However, this approach can lead to ambiguity in determining the state of individual processors, especially when
the allowable (and actual) number of faults in the system exceeds two. Theorems are formulated and proven to define the specific
characteristics of the system for organizing mutual testing, under which the described phenomenon becomes feasible, however, in one
way or another, the indices of processors with undefined states become known. The advantages of connection architectures described
by circulant graphs are highlighted, particularly the fact that the number of processors in such architectures can be arbitrary – an
attribute not always present in other cases (e.g., architectures with connection switches of the rectangular or hypercube type). Faulttolerant multiprocessor systems with an allowable number of faults T = 2, 3, and 4 are examined in detail. It is shown that in the case of
T = 2, no ambiguities arise; however, for T = 4, up to three ambiguities may occur (for T = 3 – up to two) depending on certain jumps
in the circulant graph and specific combinations of functional and non-functional processors in the system. Examples of circulant
graphs are provided where such ambiguities do not arise
Primer reporte de la temporada de anidación de la tortuga verde Chelonia mydas (Testudinata: Cheloniidae) en playa Lagarto, península de Azuero, Panamá
Authors: López-Lozano Luisa F. , Jiménez-Arias Santiago
Published: December 2024

The nesting season of the green turtle (Chelonia mydas) in the Panamanian Pacific is poorly studied, despite being a crucial event for understanding its ecology and contributing to the conservation of this endangered species. The present study aimed to characterize the nesting activity of C. mydas at Playa Lagarto, located on the Azuero Peninsula. Nighttime monitoring was conducted during the nesting season from December 2022 to March 2023. Biometric data was collected from nesting turtles; they were tagged and their nests were monitored. During the season, 15 nesting females were tagged, averaging a CCL of 91.1 ± 7.0 cm and a CCW of 85.2 ± 6.6 cm. A total of 32 nests were documented, and females exhibited a nesting success rate of 31.4%. There was a preference for nesting in the upper zone with beach vegetation, confirming the typical behavior for this species. The relationship between CCL and the reproductive capacity of nesting females (number of eggs laid) was corroborated. Regarding threats to nesting, 6.25% of the nests were poached by humans. Given the scarcity of data related to the nesting behavior of C. mydas in the Panamanian Pacific, the data obtained in this study represents crucial information for the conservation of this species on the Azuero Peninsula. Continuing the monitoring efforts to study nesting trends in this population is recommended.
Understanding body dysmorphic disorder in the context of plastic surgery: a systematic review
Authors: Juodikis Domantas , Paulauskienė Živilė , Lukoševičiūtė Gintarė
Published: December 2024

Introduction Individuals with Body Dysmorphic Disorder (BDD) frequently seek cosmetic procedures despite significant postoperative risks, a high likelihood of requiring further surgery and generally low levels of satisfaction. Consequently, it is commonly advised that individuals with BDD refrain from undergoing aesthetic surgery. Aim This article reviews the current literature on the characteristics of plastic surgery in patient populations with BDD. Material and methods A literature search was performed using PubMed, ScienceDirect, and ClinicalKey electronic databases. The search was limited to articles published in the last five years, including original works and full-text articles in English. A keyword was used to find and obtain the articles needed. Results Overall, 15 studies met our criteria, with N of participants being 1247954. We categorized our findings in the literature on varying outcomes in rhinoplasty, breast augmentation, and oculoplasty. The rate of thirty-day hospital readmission was higher for patients with psychiatric diagnoses, 2.7%, compared with 0.67% of those without psychiatric diagnoses. Women who expressed dissatisfaction with their breasts initially but spent no more than three hours daily on their physical appearance and did not employ camouflage techniques displayed an improvement after surgery. 60.6% of participants who test positive for BDD report at least one prior visit for plastic surgery. Conclusion The treatment of BDD is complex, and there is a research gap on this topic. While results may vary depending on the site and method of the procedure, cosmetic procedures generally yield unsatisfactory outcomes for patients with BDD.
Multilayer perceptron neural network applied to the neutron transport equation for the single velocity neurocomputational approach to neutronic calculations

Published: December 2024

The performance of neutronic calculations is a fundamental process for the analysis and design of nuclear reactors. However, due to the intrinsic complexity of these calculations, their solution is nearly impossible, whether through analytical or numerical methods. This work, through the application of a four-layer multilayer perceptron artificial neural network to the neutron transport equation, demonstrates the benefits of using neural computing for electronic calculations.
Images of a Doctor and a Patient in the Prose of I. S. Shmelev and V. N. Lyalin
Authors: Leonov Ivan
Published: December 2024

The article examines the artistic features of the images of a doctor and a patient in the prose of I. S. Shmelev and the modern Russian writer V. N. Lyalin. The concept of the “morbid code” is examined and the tendency towards the emergence of medical literature studies against the background of comprehensive medicalization of modern Russian society, is noted. The research was based on I. S. Shmelev’s “The Doctor’s Story” and V. N. Lyalin’s “Obsession” and “Accidental Joy.” Comparative analysis revealed that both authors rely on a Christ-centered worldview, in the context of which they examine the problems of illness, suffering, and recovery. The key to understanding the nature of human illness is the unity of the bodily and spiritual aspects. Both I. S. Shmelev and V. N. Lyalin perceive a doctor’s talent as a gift from God, and consider those who have it to be called to a special self-sacrificial service. The characters in the medical profession are not idealized, they are seen as inclined towards spiritual crises, which is expressed either through despondency and cooling towards their own profession, or through a physical illness, which can be overcome only by turning to the Evangelical tradition. Both authors introduce the image of a doctor-patient, who is able to simultaneously experience a range of spiritual and physical sufferings, as well as evaluate them from the perspective of a medical professional and a church-going Christian. The patient’s condition during the culmination of the disease is depicted by both writers using visual, auditory, olfactory, and tactile details. An important role is played by the prophetic dream motif, which may indicate an impending illness or, on the contrary, its elimination. The key motif in the morbid prose of I. S. Shmelev and V. N. Lyalin is that of “passing through death,” which is associated with the evangelical, or, more specifically, with the Golgotha symbolism.
MAN AND KNOWLEDGE: at the intersection of modern epistemology, ontology, phenomenology, philosophical anthropology
Authors: ZAHORODNIUK Valerii
Published: December 2024

The article is dedicated to the study of the relationship between the diversity of the world of knowledge and the world of man. The role of knowledge in human life is shown, the mechanism of its influence on the human world is revealed, the diversity of knowledge in the context of plurality of language images is revealed, the relationship of such philosophical disciplines as epistemology and philosophical anthropology, which deal with the problems of knowledge and man, respectively, is clarified. It is shown that сurrently, scientists are concerned about knowledge that corresponds to all the canons of classical rationality and yet turns out to be deeply irrational in its moral indifference regarding its use. It is substantiated that the times of classical rationalist euphoria from the success of science are over and it is time to reject the enlightenment illusions about science as a ‘panacea’ for all social ills. The discrimination of pre- and out-scientific knowledge does not meet the modern requirements of the new epistemology. Some anthropological and humanistic parameters of cognition are highlighted, and an attempt is made to offer a certain anthropological view of the world as a whole. It is shown that the turn from epistemology to ontology, which took place in the philosophical thought of the twentieth century, does not mean that epistemology has exhausted the possibilities of its development and should withdraw from the historical arena or relegated to the periphery of philosophical research. Moreover, nowadays we are increasingly talking about a cognitive or epistemological turn in philosophy. Classical epistemology is being replaced by various variants of modern non-classical epistemology, such as the cognitive approach, various versions of modern philosophy and sociology of science and anthropology of cognition, evolutionary and social epistemology, etc. The leading feature that defines and unites these areas of non-classical epistemologies is their anthropologisation, which testifies to the inextricable connection of such philosophical disciplines as epistemology and philosophical anthropology.
FROM A JUST WAR TO A JUST PEACE. MORAL PRINCIPLES AND LIMITS OF COMPROMISES IN WARTIMES
Authors: YOSYPENKO Serhii
Published: December 2024

The article’s reasoning is based on the definition of the nature of the war in Ukraine, which, following the Russian aggression on February 24, 2022, escalated into a full-scale conflict: this war has gradually acquired features of the total wars of the 20th century and transformed into a war of attrition, which could last for a considerable period of time. If such a war does not end with the capitulation of one of the parties, the most likely outcome would be a peace agreement involving third parties, which would take the form of a compromise and involve a renunciation by the participating parties of complete victory in the war.

Given the just nature of Ukraine's war against Russian aggression, the author raises the question of whether a peace can be considered just without a complete victory over the aggressor and without the full restoration of justice disrupted by the aggression. Drawing on the classical work of M. Walzer, the author concludes that renouncing complete victory and halting hostilities at a point when the conflict can be resolved through political means fully aligns with the concept of a just war as a limited war. To establish the moral principles and possible limits of compromises in wartime, the author turns to A. Margalit’s concept, which, in his view, continues Walzer’s reasoning by outlining the possibility of compromises for the sake of peace.

Drawing on contemporary research on political compromises, the author analyzes possible configurations of compromises in wartimes, their differences from political compromises in peacetime, and other potential outcomes of a war of attrition, including scenarios such as the capitulation of one of the parties or a modus vivendi. The article develops on the ideas of M. Walzer and A. Margalit, emphasizing that limiting the war and reaching a compromise for peace make necessary to clarify the requirements of justice. This, in turn, necessitates that the party engaged in a just war be guided by the ethics of responsibility when determining war aims, while also adhering to the fundamental distinction between good and evil in order to avoid "rotten" compromises.
SPAСETIME ANALYSIS OF AN ELECTROMAGNETIC AIRY PULSE AFTER ITS INTERACTION WITH A PLANAR BOUNDARY IN UNIFORMLY ACCELERATED RELATIVISTIC MOTION

Subject and Purpose. The transformation peculiarities that the electromagnetic pulses get when heading towards a boundary that per- forms uniformly accelerated relativistic motion are the present paper concern. A smooth non-stationarity case when the boundary velocity gradually changes from zero to the pulse velocity value is considered, with a focus on the spacetime distribution and evolution of the electromagnetic Airy pulse field.
Methods and methodology. The study and analysis are carried out by the method of Volterra integral equations which can describe electromagnetic wave propagation in a heterogeneous time-varying medium. In terms of this method, the basic initial boundary value electrodynamical problem on the electromagnetic source radiation in a heterogeneous time-varying medium is formulated, taking into ac- count the boundary and initial conditions. The resolvent method for solving the Volterra integral equation of the second kind is described. Its advantage is analytical solution capabilities and a versatility as to the primary field choice.
Results. Analytical solutions to the original integral equation have been obtained. By analysis, it has been found that the secondary field expressions have singularities that can be controlled well enough by a proper choice of numerical modeling parameters. The revealed singularities have been analytically studied. Their action on the Airy pulse was examined and illustrated through simulation modeling using the starting parameter that locates the Airy pulse at any moment in time.
Conclusions. In this work, the electromagnetic Airy pulse interaction with a boundary perfoming uniformly accelerated relativistic motion was examined using the Volterra integral equations method. The obtained analytical solutions revealed significant spacetime changes in the Airy pulses. Our analysis indicated possibilities for controlling the secondary field characteristics by a proper choice of modeling parameters. The results have been confirmed by numerical simulations. They provide a basis for further research in this area
A COMPOSITION PATCH ANTENNA
Authors:   V.N. Karazin National University of Kharkiv, Pogarsky S.
Published: December 2024

Subject and Purpose. The paper presents results of numerical simulation of a composition patch antenna with a complex form factor. The design combines two structures, specifically, a disc and an annular resonator. The annular resonator is fed via a coplanar structure that involves cut-ins of different geometries. The feed connections are effectuated pointwise, such as to provide for galvanic contact between the central conductor of the coplanar line and the annular resonator, owing to the distributed electromagnetic coupling of the annular resonator and the aperture of the coplanar line’s outer conductor. The work has been aimed at finding an optimized set of antenna parameters.
Methods and Methodology. The antenna design features a combination of two resonators and an open circuit represented by the external conductor of the coplanar line. A variety of form factors were proposed for the circuit breaking slit, including such of a straight line and of a triangle. The angular parameter of the triangular slit was a variable value. Numerical simulations were carried out within a semi-open resonator model, with proper account of all the boundary conditions as specified in the finite-element method. The form of the amplitude-frequency response was optimized according to the required values of the return loss level.
Results. The frequency and power characteristics of a composition patch antenna have been analyzed and optimized over a broad frequency range. The optimal values of the main parameters of the structure, affecting the functionality of the antenna have been determined, including form factors of the slits (cut-ins), angular characteristics of the triangle-shaped slit, the dielectric constant of the substrate, and the separation from the ground level.
Conclusions. The frequency, spectral and power characteristics of a complex patch antenna based on a combination of annular and disc resonators, sitting above a grounding base, have been investigated over a wide frequency range. Numerical simulation was performed within a methodology combining the finite-element methods and the approaches pertinent to semi-open resonators. Principal dependences of the antenna’s electrodynamic parameters upon the geometry and characteristic dimensions of the structure and material constants thereof have been identified and studied
