Abstract
Extracts obtained from common butterbur (Petasites hybridus), standardized to petasins, are existing pharmaceutical options for the treatment and/or prevention of allergic rhinitis (leaves) and migraine (rhizomes). In this study, the total phenolic content, flavonoid content, and antioxidant potential of ten samples of Croatian Petasites species (four P. hybridus, four P. albus, one P. kabli kianus, and one P. paradoxus) obtained by ultrasound-assisted extraction of leaves were compared. The total phenolic content (Folin-Ciocalteu assay) of methanolic leaf extracts ranged from 4.43 ± 0.09 to 10.76 ± 0.60 mg gallic acid equivalent g−1 dry mass (mg GAE g−1 DM) for P. hybridus and from 6.66 ± 0.43 to 19.92 ± 2.90 mg GAE g−1 DM for P. albus samples, while those of P. kablikianus and P. paradoxus were equal to 7.56 ± 0.17 mg GAE g−1 DM and 10.22 ± 0.46 mg GAE g−1 DM, respectively. Flavonoid content (AlCl3 assay) varied between 2.51 ± 0.10 and 4.03 ± 0.08 mg quercetin equivalent g−1 dry mass (mg QE g−1 DM) for P. hybridus and between 2.21 ± 0.09 and 5.22 ± 0.02 mg QE g−1 DM for P. albus samples, while those of P. kablikianus and P. paradoxus were equal to 5.59 ± 0.05 mg QE g−1 DM and 5.50 ± 0.09 mg QE g−1 DM, respectively. Antioxidant potential was in high correlation with total phenolic content (r = 0.93, p < 0.001). Due to the expected contribution of plant polyphenols and flavonoids to the activity of butterbur extracts and their observed great variabilities, determining the content of these compounds may be of interest to the pharmaceutical industry.

The Trade Potential of Infrastructure Partnerships: The Case of EU Global Gateway
Authors: Wolf André , Poli Eleonora 
Published: November 2024

Abstract
The EU‘s Global Gateway Initiative seeks to create new strategic partnerships by supporting infrastructure investments around the world. While much attention has been paid to its geopolitical implications, its long-term trade potential remains unexplored. This paper analyses the potential impact on the pattern of EU imports, focusing on product groups essential for the green transition. By combining a gravity analysis of past trade flows with scenarios for future infrastructure upgrades in Global Gateway partner countries, it sheds light on the magnitude of the trade impulses to be expected. Even with optimistic expectations for infrastructure quality, the resulting direct impact on the volume and geographical structure of the EU’s trade is very small. For Global Gateway to be successful, it needs to be developed into a driver of economic growth for the partner countries, which involves the reduction of regulatory barriers to trade and cooperation in strengthening local institutions.

Authors: Mataboge Saltiel Khololo Collen 
Published: November 2024

Abstract
The purpose of this conceptual paper is to explore sustainability in mitigating managerial challenges faced by women principals in rural primary schools. The main research question guiding this study is: “What strategies can be employed to enhance sustainability in mitigating the managerial challenges experienced by women principals in primary schools, particularly in rural areas?” This qualitative study draws upon a comprehensive review of scholarly books and articles, serving as the foundational framework for the research. Data collection is conducted through qualitative methods aligned with the interpretive paradigm allowing for a deep exploration of the experiences and perspectives of women principals. Findings from this study highlight a multitude of challenges faced by women principals in rural primary schools including limited resources, societal expectations, and gender biases. Despite these challenges, many women principals demonstrate resilience and innovative approaches in their leadership roles. The significance of this study lies in its contribution to the understanding of gender dynamics in educational leadership within rural settings, shedding light on unique challenges faced by women in these roles. Policymakers, school leaders, and aspirant deputy principals can benefit from the insights gleaned from this study. These recommendations include the need for tailored support mechanisms for women principals in rural areas, professional development opportunities focusing on leadership skills and gender equity, and policy interventions aimed at addressing systemic barriers to women's advancement in educational leadership roles. Attempts in implementing these recommendations, stakeholders can foster more inclusive and supportive environments for women principals in rural primary schools, ultimately enhancing the quality of education and leadership within these communities.

Published: November 2024

Abstract
This paper investigates the nature of the associations and the potential existence of both short-run and long-run relationships between the stock market indices of Morocco, France, Germany, the United Kingdom, China, and the United States from January 2014 to January 2024. The purpose of analyzing dynamic interconnections and contagion effects is to determine how the stock markets of these countries influence and relate to each other. The study employs a time series Vector Error Correction Model (VECM) approach, incorporating stationarity, cointegration, and Granger causality tests. Additionally, the Impulse Response Function (IRF) is used to analyze the response of variables to shocks. The bivariate Granger causality test reveals significant causal influences: from France, Germany, and the USA to Morocco; from the USA to the DAX and France; and from the UK to Germany. After establishing the Granger causal relationships, long-run and short-run relationships are further examined. Using the Johansen multivariate cointegration approach, the study suggests a long-term equilibrium among the six stock market indices over time. The short-run adjustments are analyzed using the VECM, which reveals that adjustments in the CAC 40, DAX, and MASI tend to correct deviations from equilibrium, indicating a tendency to move towards equilibrium. For the FTSE 100, S&P 500, and SSEC, the VECM captures the speed and direction of adjustments as these indices respond to short-term disruptions and work towards restoring equilibrium. The findings underscore the importance of closely connected global stock markets, which means that international regulators must coordinate their efforts to reduce the risks of contagion. Policymakers should prioritize improving financial stability through integrated frameworks considering short-term disruptions and long-term equilibrium trends.
HBIM Methodology Applied to Architectural Heritage
Authors: Angulo Edinson Christofer Angulo 
Published: November 2024

Objectives: The research aims to develop and promote the HBIM (Heritage Building Information Modeling) methodology for the conservation of architectural heritage. A dissemination model is proposed to share knowledge and good practices, with a view to improve the integrated management of cultural properties and reduce the risks of deterioration. In addition, it seeks to raise awareness among various stakeholders, including professionals and institutions, on the importance of the application of HBIM in heritage preservation.

Theoretical Framework: Building Information Modeling (BIM) is a methodology that facilitates the creation and management of digital information of historic buildings, integrating geometric, geospatial and material data. The application of HBIM in heritage projects has gained recognition for its benefits in documentation, collaboration and accuracy in conservation interventions. However, it faces challenges due to the diversity and complexity of historic buildings, as well as the lack of specific regulations.

Method: The methodology is based on a comprehensive review of the existing literature on BIM applied to heritage. Academic articles, theses and technical papers have been analyzed to consolidate a robust theoretical framework and establish best practices for the conservation of historic buildings. This review identified trends and challenges, and generated recommendations for effective HBIM implementation.

Results and Discussion: The findings highlight the potential of HBIM to transform architectural heritage conservation. The methodology allows the creation of detailed 3D models, integrating information on geometry, materials and construction processes, facilitating the understanding of the structure and condition of buildings. However, challenges include the high cost of detailed models and the need for heritage-specific standards, which limits the adoption of HBIM in certain contexts.

Research Implications: At the theoretical level, this research enriches knowledge on the integration of advanced technologies in heritage conservation. In practice, HBIM makes it possible to anticipate material aging problems and to prioritize sustainable conservation actions, which underlines the need to train professionals in these technologies. The adoption of HBIM implies developing technical skills in the conservation sector.

Originality/Value: This paper highlights the innovation of HBIM in architectural heritage management through the use of advanced technologies such as laser scanning and photogrammetry. The ability to create detailed digital models enables accurate and sustainable interventions in historic buildings to be documented and planned. In addition, HBIM facilitates a multidisciplinary approach, integrating technology, history and architectural conservation to effectively and sustainably preserve cultural heritage.
Генератор стохастических тестов с ограниченным моделированием выполнения
Authors: А.С. Куцаев 
Published: November 2024

Преимущество генераторов случайных тестов в простоте их применения. Стохастическое тестирование выявляет как обычные, так и специфические ошибки (редкие сочетания и недочеты спецификации). Тестирование составляющих проекта требует задания большого числа параметров, связанных с этими составляющими. Это вызывает необходимость автоматизации и развития модели целевого устройства. Для этого служит встроенный специализированный симулятор. Его использование позволяет снять ряд ограничений, в том числе при применении циклов для тестирования способов повышения быстродействия. Дальнейшее развитие возможностей генераторов случайных тестов требует автоматизировать средства подготовки шаблонов.
The advantage of random test generators is the simplicity of use. Stochastic testing can detect both ordinary and specific errors (due to rarely occurred combinations and defects of specification). When creating tests that are intended to verify the components of the project, one has to set many control parameters of the generator. This induces the necessity of the automation and the improvement of the target device model. A helpful instrument that improves the creation of tests is a specialized built-in simulator. Its application removes some limitations, e.g. using loops when testing the facilities of acceleration. A further improvement of random test generators forces to the automation of the development of templates.

Методы снижения ресурсоёмкости операционной системы жёсткого реального времени
Authors: А.А. Асонов , А.Н. Годунов , В.А. Солдатов 
Published: November 2024

Несмотря на общий рост объемов доступной оперативной памяти, существует класс задач, работающих в жестком реальном времени, для которых оперативная память является лимитированным ре-сурсом. В задачах этого класса накладываются ограничения на ресурсы, используемые операционной систе-мой реального времени (ОСРВ). Объем памяти, требуемой для ОСРВ, предлагается сократить за счет выпол-нения программного кода целевой системы из постоянного запоминающего устройства и путем расширения возможностей масштабирования уже существующей ОСРВ. Такой подход позволяет достичь существенной экономии памяти без больших переделок в ОСРВ, что позволяет снизить трудоемкость разработки и обеспе-чить высокую надежность ОСРВ. Некоторые части ОСРВ (обработка прерываний и исключительных ситуа-ций, поддержка многопоточности, служба времени, распределение памяти) являются обязательными, и их нельзя полностью исключить из целевого образа, а можно только сократить в той или иной степени. Все ос-тальные части операционной системы могут быть либо существенно сокращены, либо вовсе исключены, если они не используются прикладной программой или пакетом поддержки модуля (ППМ). К ним относятся сред-ства взаимодействия с сетью, файловые системы, блочные устройства, базовые операции ввода/вывода, сред-ства отладки, условные переменные, очереди сообщений, таймеры, региональные настройки, программные каналы, сигналы, семафоры.
Despite the general growth in the amount of available RAM, there is a number of tasks that operate under hard real-time conditions, for which RAM is a limited resource. In such tasks, restrictions are imposed on resources used by a real-time operating system (RTOS). To reduce the memory size required for the RTOS, it is suggested to execute the code of the target system straight from ROM and enhance scalability of the existing OS. This approach allows to reduce the software development efforts hereby providing high reliability of RTOS. Some components of the RTOS (interrupts and exceptions handling, multithreading, time service, memory allocation) are essential and cannot be completely removed from the target image, but can only be reduced, to some extent. All other components of the operating system can be either significantly reduced, or completely removed, if they are not used by the application program or the board support package (BSP). These include networking, file systems, block devices, basic I/O operations, debugging tools, conditional variables, message queues, timers, regional settings, program channels, signals, semaphores.

Суперкомпьютер и дискретная топология
Authors: Г.Г. Рябов , М.Ш. Сургуладзе 
Published: November 2024

Для моделирования объектов дискретной топологии привлекаются суперкомпьютерные системы, нередко из списка ТОР-500, что вполне объяснимо комбинаторным характером большинства задач, особенно при исследовании динамики перестроек таких структур [2,4]. В статье рассмотрены три метода кодирования, которые имеют перспективы развития и связаны с распараллеливанием вычислений в рассматриваемой области: 1. Кодирование кубических комплексов. 2. Кодирование для вычисления переходных вероятностей в цепях Маркова при перестройках триан-гуляций евклидовых пространств. 3. Кодирование топологических ситуаций при преобразованиях комплексов - дискретных аналогов гомотопных преобразований. База, выбранная для геометрико-топологических объектов, обладает «минимальными» математическими ресурсами (целые точки и примитивные вектора в евклидовых пространствах).
For simulation of objects of discrete topology, supercomputers are often used. This can be explained by the combinatorial nature of the problems examined, especially in the study of the dynamics of rearrangements of such structures. In this paper, we consider three methods of coding associated with the parallelization of computations: (1) coding of cubic complexes; (2) coding for the calculation of transition probabilities in Markov chains in the reconstructions of triangulations of Euclidean spaces; (3) coding of topological situations in the transformations of complexes, i.e., discrete analogs of homotopic transformation. The base chosen for the geometric and topological objects possesses “minimal” mathematical resources (integer points and primitive vectors in Euclidean spaces).
Изменения свойств модели Изинга и её термодинамических характеристик при добавлении шума в матричные элементы

Published: November 2024

Подсчёт вероятностей во многих задачах компьютерного зрения и машинного обучения сводится к подсчёту нормировочной константы (статистической суммы). В данной работе рассматривается двумерная модель Изинга с ближайшими соседями, когда взаимодействие между соседями имеет постоянное среднее значение с небольшим шумом. Проводятся численные эксперименты по вычислению нормировочной константы для случая, когда шум в матричных элементах плавно возрастает, приводится анализ полученных результатов и сравнение с решением Онсагера
The calculation of probabilities in many problems of computer vision and machine learning is reduced to the finding of a normalizing constant (statistical sum). In the paper a two-dimensional nearest-neighboring Ising model with almost constant average interaction between neighbors is considered. We carry out numerical experiments to compute the normalizing constant for the case in which the noise in grid elements grows smoothly, analyze the results and compare them with Onsager’s solution
Воздействие тепловой обратной связи на температуру кристалла микросхемы
Authors: А.Г. Мадера 
Published: November 2024

Потребляемая микросхемой мощность преобразуется в тепло, которое приводит к нагрева-нию микросхемы. В силу значительной зависимости электрических параметров микросхемы от температуры ее мощность потребления подвергается изменению, которое, в свою очередь, изменяет температуру и, как следствие, мощность потребления. Взаимно-обусловленное взаимодействие и влияние параметров электри-ческого и теплового режимов друг на друга, возникающее в процессе работы микросхемы, называется тепло-вой обратной связью. Тепловая обратная связь присуща любым электронным полупроводниковым устрой-ствам и неустранима. Воздействие тепловой обратной связи может как положительным, так и отрицатель-ным. При положительной тепловой обратной связи потребляемая мощность и температура микросхемы уве-личиваются, а при отрицательной уменьшаются. Результаты расчетов показывают, что адекватное моделиро-вание электрических и тепловых параметров микросхем невозможно без учета воздействия тепловой обрат-ной связи, и пренебрежение ею приводит к значительным погрешностям проектирования микросхем и созда-нию неконкурентоспособных электронных систем
The power consumed by the microchip is converted into heat, which leads to the heating of the micro-circuit. Due to the significant dependence of the electrical parameters of the semiconductor chip on temperature, its power consumption is subject to a change, which in turn changes the temperature and, as a consequence, the power consumption. The mutually conditioned interaction and the influence of the electric and thermal parameters on each other, arising during the operation of the microcircuit, is called thermal feedback. Thermal feedback is inherent in any electronic semiconductor devices and is not removable. The thermal feedback effect can be either positive or nega-tive. At the positive thermal feedback, the power consumption and temperature of the chip increase, and with a nega-tive decrease. The results of the calculations show that adequate simulation of the electrical and thermal parameters of microcircuits is impossible without taking into account the effect of thermal feedback, and neglecting it leads to significant errors in the design of microchips and the creation of noncompetitive electronic systems
