Background and Purpose:A Farsi version of the Heartland Forgiveness Scale (HFS-F) for assessing forgiveness in Iranian cardiovascular patients was not available. This study aimed to determine the validity and reliability of the Farsi version of HFS in this population.Methods:In this methodological cross-sectional research design, 400 Iranian cardiovascular patients completed the HFS-F between October 2019 and January 2020. We assessed the characteristics, content, and both exploratory and confirmatory construct validity of the measures. To evaluate the reliability and construct validity of the HFS-F, we calculated Cronbach’s alpha, McDonald’s omega, and the Intraclass Correlation Coefficient.Results:Three factors were identified following confirmatory and deterministic factor analyses. The extracted factors demonstrated satisfactory reliability, exceeding a threshold of 0.7.Conclusions:The HFS-F exhibited a robust level of validity and reliability, rendering it a suitable instrument for future research endeavors.
Action des bois sur le fer (2e publication)
Authors: Savard J. , Caumartin L. , Lambert C.
Published: September 2024

Les auteurs démontrent qu'il faut distinguer la corrosivité du bois vis-à-vis du fer et les attaques du bois par le fer : les deux phénomènes ne sont pas nécessairement parallèles. Un bois attaqué peut être détecté à l'analyse par un taux d'essence plus élevé qu'un bois normal.Il a toujours été observé que les ions fer attaquent le bois même lorsque les substances essentielles ont été complètement éliminées : l'attaque est alors beaucoup moins différenciée que dans le cas du bois brut.Au cours de ce test de corrosivité, toutes les essences utilisées ont absorbé sensiblement les mêmes quantités de fer. Le phénomène ne modifie donc pas le classement établi par l'essai précédent à 45° C.Ce test a été appliqué aux bois d'Afo et d'Okoumé.

Authors:   Voronezh Institute of the Ministry of Internal Affairs of Russia, Kuleshov Anton A.
Published: September 2024

The research considers the peculiarities of professional competence formation among employees of the internal affairs bodies of the Russian Federation in educational organizations of the Ministry of Internal Affairs of Russia. The research methodology includes the analysis of scientific literature, normative legal acts, induction, deduction and other general scientific methods of cognition. In modern conditions, employees of internal affairs agencies face a wide range of tasks that require not only deep knowledge and professional skills, but also the ability to critically analyze, effectively interact with citizens and apply legal norms. The existing system of professional training in educational organizations of the Ministry of Internal Affairs of Russia has specific features, such as closeness, combination of academic and official activities, which limits the possibilities of cadets and trainees to gain practical experience in interacting with citizens. The integration of legal clinics into the educational process makes it possible to overcome these limitations by providing students with the opportunity to directly participate in the provision of free legal assistance and legal education of the population. This helps to develop the necessary professional competencies and improve the quality of training for internal affairs agencies. The research presents a list of competencies formed by cadets and trainees in the process of working in legal clinics, based on the analysis of which a conclusion is made about the possible usefulness of using legal clinics in the pedagogical process of educational organizations of the Ministry of Internal Affairs of Russia.

Published: September 2024

We consider the issue of high competition in entering medical universities, especially for state-funded places. The connection between successful mastering of the educational program of the 1st year of higher education and high starting indicators of applicants is studied. It is revealed that students with honour certificate make up one fifth of the total number of entrants. A new approach to analyzing their academic performance is proposed. The factors influencing their academic performance are listed: gold medal, Unified State Examination results, social activity and others. Multidisciplinary data on students from the Udmurt Republic, the Republic of Tatarstan and other regions for the period 2018–2022 are collected and analyzed. This research reveals differences in the performance of students with honours certificate by region, gender, and place of residence; in most cases, there is a correlation between marks in the honours certificate and USE results, but 11.6 % of enrollees scored less than 210 points for three subjects (chemistry, biology, and Russian language). The analysis of academic performance in natural science disciplines of the first year demonstrates that the average score for the university course is lower than for the school course, which may be due to differences in the organization of the educational process, social and motivational factors. In the future, the monitoring of the performance of students who have presented the honour certificate, from the first to the final year of study can affect the optimization of targeted assistance to achieve success in education. The conducted research is one of few both in Russia and abroad. The cognitive characteristics of those who entered medical schools with high starting indicators in terms of analyzing and predicting their academic performance are not sufficiently researched and may be of interest to the scientific pedagogical community.

Published: September 2024

We analyze the features of emotional intelligence formation and development at the student age as emotional intelligence can be a tool to understand students’ own sensory state and recognize the mood of a communication partner, their emotional climate, to manage further their own and others’ actions arising under the influence of certain emotions and anticipating future consequences. The factors influencing the emotional balance of a generation Z student, the consequences of constructive and destructive emotional manifestations at this age are revealed. Special emphasis is placed on the gender characteristics in the development of the emotional intelligence of the student's personality. Students’ emotional intelligence characteristics are rapid alternation of emotions (often opposite in nature); exposure to various external factors; high risk of emotional burnout; a tendency to restrain their feelings (not to demonstrate them to others); duality of emotions in relation to one object; prolonged concentration on their own emotions (often negative). The possibilities of cinematography in the context of its influence on the development of students' emotional intelligence are substantiated. Three considered types of information used in the creation of the film that affect the emotional sphere of students are motivational, ideological and directly emotional types of information. Film directors use number of film techniques to exert an emotional influence on the student-viewer, for example, Dutch angle, hand-in-waistcoat, panoramic photography, color rendering, and the use of musical compositions. The specificity of the influence of cinematography on students with different levels of emotional sensitivity is revealed.

U središtu interesa ovog rada jest spuštanje dobne granice za dodjeljivanje aktivnog biračkog prava. U proteklih 15-ak godina u državama koje su spustile dobnu granicu za stjecanje aktivnog biračkog prava s 18 na 16 godina objavljeno je više studija u kojima se nastoji propitati neke od argumenata koji se obično iznose u normativnim raspravama o prednostima i nedostatcima spuštanja dobne granice. Te studije bave se situacijom u pojedinim državama i predstavljaju vrlo vrijedan doprinos uvidima i raspra vama o navedenoj temi. Međutim, u okviru znanstvene literature rijetke su analize koje bi pokušale sin tetizirati glavne rezultate navedenih istraživanja i izvesti neke općenitije zaključke. Upravo je to glavni cilj ovoga rada. Na temelju pregleda i analize istraživanja provedenih u Austriji, Škotskoj, Njemačkoj i Norveškoj prikazuju se i sintetiziraju rezultati tih istraživanja te se nastoje izvesti određeni zaključci. Na vedena istraživanja u puno većoj mjeri podupiru argumente zagovornika nego argumente protivnika spuštanja dobne granice za stjecanje aktivnog biračkog prava.‎‎

Published: September 2024

The central border that divides the states of Puebla and Veracruz is characterized by being the highest territorial limit in Mexico; it is composed of three of the highest mountains in the country. This border reaches a length of 100 km, forming a watershed that continuously exceeds 3000 m in altitude. Due to its elevation, winter freezing conditions are frequent; however, due to changing climate patterns, in recent winter seasons, severe frosts and snowfalls have occurred at elevations well below the main peaks, affecting the health of thousands of vulnerable residents of both states surrounding this mountain range. Because the 2021-2022 winter season was one of the most intense in all North America, with severe impacts in Mexico as a result of freezing temperatures and snowfall, this work analyzes the winter conditions in 2021-2022 through the monitoring of frontal systems and the analysis of data from automatic meteorological stations near the study area. From the records, the lower limit of surface freezing was estimated for each arrival of cold air masses; the occurrence of snowfall was determined by remote sensing, and the area of snow cover was also calculated. At the same time, the population affected by freezing weather conditions was estimated. The surface freezing starts at elevations as low as 2259 m, covering an area of up to 2949 km2, which corresponds to the entire study region, affecting 139 towns in Veracruz and 163 in Puebla.
How Does the Threshold for Urban Household Registration in China Affect the Willingness of Rural to Urban Migrant Population to Settle Down?
Authors: ZHANG Qian qian , Su Li feng , An Chao fan
Published: September 2024

The scale of China's floating population is very large, and it is a key group that needs attention in promoting the equalization of basic public services. This study explores the impact and mechanism of adjusting the urban household registration threshold on the acquisition of citizenship status by the "rural-urban" floating population, with the household registration threshold as the link. It was found that the threshold for household registration has an impact on the willingness of rural urban migrant population to settle down from two aspects. On the one hand, a high threshold for household registration implies the unaffordability of obtaining citizenship status for the "rural-urban" migrant population, which has a significant crowding out effect on their willingness to settle down. Moreover, the high skilled "rural-urban" migrant population without housing is more sensitive to the high threshold for household registration. On the other hand, from the perspective of urban scale, the increase in the threshold for household registration has had a crowding out effect on the floating population for Type I large cities, mega cities, and super large cities. The increase in the threshold for settling in mega cities has the strongest crowding out effect on the floating population, which means that as the urban population expands, the welfare benefits enjoyed by the floating population in these cities will decrease, leading them to be more inclined to leave these cities and seek development opportunities in other cities. This study effectively answers how the threshold for household registration affects the willingness of rural urban migrant population to settle, providing mathematical support for urban development.
A Game-Theoretic Model of Global AI Development Race: Dynamics of Domination and Technological Catch-up
Authors: Montgomery Richard Murdoch
Published: September 2024

This paper presents a novel game-theoretic model simulating the global artificial intelligence (AI) development race among nations. We introduce a dynamic system of equations that captures the complex interplay between a country's development level, investment strategies, market share, and the possibility of technological domination. The model incorporates key features of technological races, including returns subject to diminishing marginal utility, exponentially increasing costs, market dynamics, and strategic investment decisions based on relative market positions. Through Monte Carlo simulations, we analyze various scenarios of the AI race, focusing on the emergence of dominant players and the challenges faced by countries attempting to catch up. Our results indicate a tendency towards oligopolistic market structures, with a few countries achieving technological domination while others struggle to close the gap. The model provides insights into the potential trajectories of global AI development and the conditions under which technological leapfrogging might occur. These findings have implications for policymakers and researchers in understanding the dynamics of technological races and formulating strategies for national AI development.

Published: September 2024

Cirrhosis is a critical global health issue, responsible for 2.4% of deaths worldwide in 2019. The Global Burden of Disease Study reported a near doubling of decompensated cirrhosis cases from 1990 to 2017. In the U.S., cirrhosis is the 12th leading cause of death and often requires hospitali-zation and procedural interventions for severe complications such as hepatocellular carcinoma, ascites, hepatic encephalopathy, and variceal bleeding. This study aims to identify racial, ethnic, and socioeconomic disparities in receiving critical interventions among U.S. patients with de-compensated cirrhosis during 2020-2021. We conducted a retrospective cross-sectional analysis using 2020-2021 National Inpatient Sample data of adult patients (≥18 years) with cirrhosis-related and cirrhosis complication-related ICD-10 codes and who underwent procedures for cirrhosis-related indications such as esophagogastroduodenoscopy (EGD) for variceal hemor-rhage, transjugular intrahepatic portosystemic shunt (TIPS) for variceal hemorrhage or refractory ascites, hemodialysis for acute kidney failure or hepatorenal syndrome, and liver transplantation We collected data on patient baseline clinicodemographic and procedural outcomes. Statistical analyses included multivariable logistic regression to assess for associations with outcomes. There were significant disparities in procedure utilization: White and Hispanic patients more likely than Black patients to receive EGD and TIPS, while Black and Hispanic patients had higher odds of receiving hemodialysis. Insurance type also influenced access, with Private/HMO insurance holders having higher odds of undergoing procedures. These findings underscore the need for targeted interventions to address healthcare inequities.

Published: September 2024

This paper presents an innovative method to tackle the predictive-control challenges associated with large-scale fuzzy polynomial systems comprising interconnected polynomial fuzzy systems. This study models large-scale nonlinear fuzzy systems in a polynomial framework, which can reduce the number of fuzzy rules. We derive the conditions for controller synthesis in the main theorem using the Lyapunov theory and sum-of-squares technique. Simulation results confirm the validity and efficiency of this approach.
Machine Learning Algorithms for Predicting and Estimating Book Borrowing in University Libraries
Authors: Zhang Huimin
Published: September 2024

Accurate prediction of borrowing volume of library books is conducive to the decision-making of the managers. This study briefly introduces the backpropagation neural network (BPNN) algorithm used to predict the borrowing volume of university libraries. The factor analysis method and genetic algorithm were employed to optimize the BPNN algorithm to improve its prediction performance. The book borrowing records of 2022 from Handan College Library were considered the subject of simulation experiments. The designed algorithm was compared with the extreme gradient boosting and traditional BPNN algorithms in the experiments. The results showed that average borrowing time, book lending ratio, book return ratio, and average grade of borrowers could be used as the input features of BPNN. The improved BPNN algorithm demonstrated faster convergence and a smaller error during training. The borrowing volume predicted by the improved BPNN algorithm closely matched the actual volume, and the increase in prediction time did not lead to a significant change in the prediction error.
RESEARCH OF THE COMBUSTION PARAMETERS OF GASOLINE WITH ADDITIONAL HYDROGEN IN A SPARK-IGNITION ENGINE IN EXTERNAL SPEED CHARACTERISTIC MODES
Authors: Marchenko A.P. , Mishchenko M.T.
Published: September 2024

The directions of development and improvement of road transport around the world are inextricably linked to the desire to reduce the use of cars “on traditional fuels” due to limited oil and environmental safety of mankind. Since the modes of external speed characteristic are the most typical for the operation of cars in cities, the study of environmental performance of engines in these modes is an urgent task. Therefore, finding ways to reduce carbon dioxide emissions from automobile engines at high-speed modes is an urgent task. The rapid growth in the number of cars with internal combustion engines and the inevitable decline in world oil reserves necessitate the development and implementation of energy-saving technologies and the use of alternative fuels. Research aimed at finding ways to improve the fuel efficiency and environmental performance of automotive engines is relevant. One of the promising areas is the influence on the combustion process in gasoline engines by using additives of alternative fuels, which include hydrogen. The presented study of the parameters of combustion of gasoline with hydrogen additive in a spark ignition engine at external speed characteristics is a comprehensive analysis of the combustion process of a gasoline-hydrogen mixture and determination of its effect on the concentration of carbon dioxide in exhaust gases by developing a mathematical model that takes into account the composition of the mixture components and features of the combustion process, allows for sufficiently accurate calculation of the operating process of an engine with hydrogen additive at ψ ≤ 10%, its identification by the results of experiments.  In the course of the study, dependencies were developed to determine the combustion parameters of the Wiebe model, taking into account the addition of hydrogen to gasoline in the modes of external speed characteristics, and the effect of hydrogen addition on the concentration of CO2 in exhaust gases was analyzed. It is shown that with an increase in the hydrogen additive to 10% by mass fraction to gasoline, there is a decrease in CO2 emissions to almost 30% in the external speed characteristic modes, which corresponds to modern environmental standards for gasoline internal combustion engines.
SELECTION OF GAS MIXER PARAMETERS FOR DIESEL CONVERSION GENERATOR MOTOR IN GAS DIESEL
Authors: Lievtierov A.M. , Avramenko A.M.
Published: September 2024

According to literary sources, options for converting diesel engines into dual-fuel engines for operation on any fuel, in particular, natural gas (NG), were analyzed. The conversion method with external mixture formation and an ignition dose of liquid fuel involves the preparation of a gas-air mixture of the required composition in a special device. The methodology for choosing the design parameters of the gas mixer for the organization of the work process of a V-shaped diesel engine type 12Ch 15/17.5, converted into a gas diesel, which works as part of a motor-generator unit of backup power supply, is given. The basic design of the diesel motor-generator was analyzed. A comparative calculation of the working processes of diesel and gas-diesel variants of execution (with an ignition dose of diesel fuel of 10%) was carried out. The requirements for the design and location of the gas mixer have been formed. In the work, using 3D modeling technologies, the geometry of the gas mixer and its flow part were formed. Using the method of finite volumes, the calculation grid was synthesized and its adaptation near solid walls was carried out. Next, a series of numerical experiments was conducted in a three-dimensional setting to evaluate the throughput and quality of mixing network methane with air (when the robot is operating at typical operating modes). The distribution of flow velocities in the vertical and horizontal planes of the flow part of the gas mixer was evaluated, the change in pressure along the height of the gas mixer and the distribution of the mass fraction of methane in the flow part of the engine intake tract were analyzed, and scientific and practical recommendations were developed to ensure the efficient operation of gas diesel as part of a motor-generator installation. It is shown that the proposed design of the gas mixer allows effective mixing of methane with air when operating in the entire power range of the considered engine. The use of 3D modeling technologies, with the use of modern numerical methods, allows you to assess the operating conditions of the mixture by macro indicators and in local sub-regions, which allows, in the future, to develop recommendations for increasing the efficiency of the process of preparing the fuel-air mixture.

The work describes approaches to problem solving of operational and effective improvement of the technical and tactical characteristics of military and civilian machines: tanks, armored vehicles, diesel locomotives, turbo-expander power plants, autonomous power plants of strategic objects, etc. For this purpose, fundamentally new methods of strengthening of contacting machines elements are being developed. These methods combine the advantages of discrete and continuous strengthening methods, which have largely exhausted their capabilities by now. Qualitative features and advantages of proposed discrete-continuous strengthening methods require effective implementation. We are talking about the justification of progressive technical solutions based on the criteria of strength and durability. For this purpose, the methodology of multi-criteria synthesis in the expanded space of design and technological parameters will be improved. In addition, as a basis for substantiating advanced technological solutions, a set of related problems of analysis of the stress-strain state, friction and wear is formed. Therefore, based on the improved system approach, a much higher level of strength and durability of the reinforced structural parts is achieved than with traditional methods. The results of test problems solving are illustrated. In the result, micro-macromodels are generalized to determine the joint influence of structural and technological factors, microstructure, physical and mechanical properties of materials of reinforced layers on the contact interaction and stress-strain state of representative fragments of the system of discrete-continuous reinforced bodies. The results of analysis of combined influence of structural and technological factors, microstructure, physical and mechanical properties of materials reinforced layers have been established on the contact interaction and stress-strain state of test representative fragments of the system of discrete-continuously reinforced bodies. At the same time, a significant influence of reinforced layers properties was established on strength of contacting bodies.

Published: September 2024

This study aims to analyze the halal industry's influence on economic growth in Islamic countries. The research gap in this study is that previous studies have indicated a diverse influence of halal industry variables on economic growth. Therefore, this study aims to provide a deeper understanding of the role of the halal industry in enhancing economic growth in Islamic countries. This study is quantitative research using secondary data categorized as panel data. The data consist of annual figures on Islamic Finance, Halal Food, Halal Travel, Halal Fashion, Halal Media and Recreation, and Economic Growth from 2014 to 2020 in 10 Islamic countries, obtained from the State of the Global Islamic Economy (SGIE) Report and the World Bank. The data analysis technique used is Panel VECM. The study results show that only the Islamic Finance variable positively affects economic growth in the short term. In contrast, the other variables show no effect or a negative effect on economic growth.

 
Case study of continental-scale hydrologic modeling’s ability to predict daily streamflow percentiles for regulatory application
Authors: Gutenson Joseph , Sparrow Kent , Brown Stephen , Wahl Mark , Gordon Kyle
Published: September 2024

Regulatory practitioners use hydroclimatic data to provide context to observations typically collected through field site visits and aerial imagery analysis. In the absence of site-specific data, regulatory practitioners must use proxy hydroclimatic data and models to assess a stream's hydroclimatology. One intent of current-generation continental-scale hydrologic models is to provide such hydrologic context to ungaged watersheds. In this study, the ability of two state-of-the-art, operational, continental-scale hydrologic modeling frameworks, the National Water Model and the Group on Earth Observation Global Water Sustainability (GEOGloWS) European Centre for Medium-Range Weather Forecasts (ECMWF) Streamflow Model, to produce daily streamflow percentiles and categorical estimates of the streamflow normalcy was examined. The modeled stream-flow percentiles were compared to observed daily streamflow percentiles at four United States Geological Survey stream gages. The model's performance was then compared to a baseline assessment methodology, the Antecedent Precipitation Tool. Results indicated that, when compared to baseline assessment techniques, the accuracy of the National Water Model (NWM) or GEOGloWS ECMWF Streamflow Model was greater than the accuracy of the baseline assessment methodology at four stream gage locations. The NWM performed best at three of the four gages. This work highlighted a novel application of current-generation continental-scale hydrologic models.
A Tool to Visualise and Interact with Probability Density Functions - Development and Case Study
Authors: Evans Kristian Paul , Williams Arron
Published: September 2024

This article is an overview of the design, implementation and testing of a tool to visualise and interact with probability density functions. The tool is a desktop application implemented entirely in Python using the tkinter library for the graphical user interface. The project was undertaken as part of a collaboration between Mathematics and Computer Science. The goal of the application is to provide a simple user interface for teaching staff and students to visualise and interact with probability density functions. The application should help improve studentsâ€™ understanding of the concepts involved and its simple design should reduce the complexity barrier that often faces users when using technology in the classroom. Following initial testing, a variety of teaching staff were involved with trialling the tool, together with student volunteers from a first-year and second-year statistics module at Swansea University. Feedback was obtained and evaluated from all participants. For the teaching staff group, we found thatÂ all four participants strongly agreed that the application is easy to use and that the user interface was not distracting. Furthermore,Â all teaching staff stated that they would consider using the application in their own teaching and all would recommend using the application to a colleague/friend. For the student volunteer group,Â all twelve participants either agreed or strongly agreed with the statements that the application is easy to use, useful and not distracting. Similar to the teaching staff group, all the student participants stated that they would consider using the application in their own learning and all would recommend the application to a friend. A full analysis of the survey results is provided in the Feedback section.

Making the Move from "Med Math" to Medication Administration and Safety
Authors: Stewart Traci
Published: September 2024

The World Health Organization (WHO) recognized medication errors as a global health problem in 2017 highlighting them as a top patient safety challenge (World Health Organization, 2023). The American Association of Colleges of Nursing (AACN) highlights quality and safety one of the essentials of nursing (2021). In response to declining medication math scores and the emphasis on patient safety, one Midwest United States nursing program updated their curriculum to address medication administration and safety on exams instead of just “med math” as dosage calculation. Addressing the varying skills and knowledge of foundational mathematical concepts for nursing students entering and progressing throughout the program remains an area of further study.

حظيت السمية الخلوية للمستخلصات النباتية باهتمام كبير في السنوات الأخيرة لتقييم نشاطها ضد الأورام. تركز الوقاية الكيميائية من السرطان على السمية الخلوية للمستخلصات النباتية لتكون سامة تجاه خطوط الخلايا السرطانية دون أن تؤثر على الخلايا الطبيعية. الهدف من هذه الدراسة هو تقييم السمية الخلوية لمستخلصي الزنجبيل و أوراق الزيتون ومزيجهما بنسبة 1: 1 تجاه خطوط خلايا RD وتقدير فعالية هذه المسخلصات ضد الاجهاد التاكسدي  بدلالة SOD و MDA. تم الحصول على المستخلصات الكحولية لكل من الزنجبيل وأوراق الزيتون بطريقة السوكسيلت. وحضر المستخلص الثالث بخلط كميات متساوية من مستخلص أوراق الزيتون والزنجبيل بنسبة 1: 1. تم تحضير اطباق من خطوط الخلايا RD وخطوط الخلايا الاعتيادية وتم اختبار تراكيز مختلفة من المستخلصات المحضرة (12.5 - 800 ميكروغرام / مل) لتسجيل فعالياتهم تجاه كل من RD وخطوط الخلايا الطبيعية. . كذلك ، تم تقدير  مستوى انزيم  SOD و MDA اعتمادًا على طرائق العمل الخاصة بهما. اظهرت النتائج  وجود فرق معنوي بين السمية الخلوية للتراكيز المدروسة لكل مستخلص تجاه خطوط الخلايا RD، اذ انخفضت قابلية بقاء خطوط الخلايا RD مع زيادة تراكيز المستخلصات ، وفي نفس الوقت لم تؤثر تلك  المستخلصات على خطوط الخلايا الطبيعية. كذلك بينت النتائج ازدياد مستويات SOD مع زيادة تركيز المستخلص على عكس مستويات MDA التي انخفضت مع زيادة تراكيز المستخلص. يمكن الاستنتاج بان نشاط المستخلصات المحضرة تجاه خطوط الخلايا RD دون التأثير على خطوط الخلايا الطبيعية يعزز مبادئ المنع الكيميائي للسرطان ، إلى جانب الخصائص المضادة للأكسدة التي يمكن أن تقلل من الإجهاد التأكسدي الذي يصاحب الخلايا السرطانية  وتنشيط العوامل الطبيعية المضادة للاكسدة في جسم الانسان.

تشكل متلازمة الجهاز التنفسي الحادة الوخيمة فيروس كورونا 2 (SARS-CoV-2) تهديدًا عالميًا، مما يؤثر على الملايين في جميع أنحاء العالم. في حين أن الكشف الآلي عن التهابات الرئة من خلال التصوير المقطعي المحوسب (CT) يعد بديلاً واعداً، فإن تجزئة المناطق المصابة من شرائح الأشعة المقطعية لا تزال صعبة بسبب حدود العدوى منخفضة التباين والمظاهر غير الواضحة. ولمواجهة هذا التحدي، تم اقتراح نموذج للتعلم العميق يسمى ECGANCOVID-Net للكشف عن المناطق المصابة وتحديدها في الصور المقطعية للصدر. يستخدم نموذجنا أداة القطع الهرمي الدلالي للكشف عن مناطق عدوى الرئة الناجمة عن فيروس كورونا في الصور الطبية المقطعية. ويتكون النموذج من عنصرين، هما نماذج U-CGAN-Net. تم تصميم الشبكة العصبية الأولية، UCGAN-Net1، للكشف عن حمة الرئة. وبعد ذلك، تعمل الشبكة العصبية الثانية، UCGAN-Net 2، على الرئتين المجزأتين لتحديد المناطق المحددة المتأثرة بآفات كوفيد-19 بدقة. تتكون شبكة UCGAN-Net من شبكة الخصومة التوليدية المشروطة (CGAN) التي تتضمن مولدًا ومميزًا مُكيَّفًا. بالإضافة إلى ذلك، يستخدم نموذجنا تقنيات زيادة البيانات لمعالجة مسألة بيانات التدريب المحدودة. ومن خلال التجارب المكثفة، تم اكتشاف أن المنهجية المقترحة تظهر أداءً متفوقًا مقارنة بالتقنيات المقترحة مؤخرًا. ويتجلى هذا بشكل خاص في الأداء العام المحسن لنموذجنا عند التحديد الدقيق لموقع الآفات الصغيرة. أظهرت شبكة ECGANCOVID المقترحة أداءً استثنائيًا في تجزئة آفات كوفيد-19، وحققت أداء توطين أعلى مع معامل تشابه النرد (DSC) بنسبة 84.5% والتقاطع عبر الاتحاد (IOU). بالإضافة إلى ذلك، خضع النموذج المقترح للتحقق الخارجي باستخدام مجموعة البيانات الغير مرئية، مما أدى إلى معامل تشابه النرد بنسبة 69.7%.
