History of the cutaneous microcirculation from antiquity to modern times
Authors: Jung F.
Published: February 2024

This review spans a wide arc from the first observations of the early anatomists to the present day. William Harvey was the first to describe the heart as the centre of the large and small circulatory system. He thus replaced the previously valid system of Galenos, It was Marcello Malpighi who first described that the capillary system connects the arteries with the veins. In 1688 Antoni van Leeuwenhoek (1632–1686) confirmed these results with a paper on capillary perfusion in the caudal fin of the glass eel. It was then Hermann Boerhave (1668–1738, Leiden) who was the first to carry out microcirculation tests on patients. He studied the microcirculation in the human bulbar conjunctiva. Even today, microcirculation studies in the conjunctiva bulbi of patients are carried out today. Until 1831, it was never quite clear whether the observations reported belonged mainly to the field of microcirculation, which had not yet been defined. This was done in Great Britain by Marshall Hall (1790–1857). Technical Improvements allowed increasingly sophisticated studies of the morphological structure of the terminal vasculature. According to Gustav Ricker (1870–1948, Vienna), the terminal vasculature comprises the functional unit of the smallest arteries, arterioles, capillaries and venules. In 1921 it was still thought that the blood circulation was the sole response to the pumping action of the heart. Even the classic work by Bayliss on the myogenic hypothesis (later referred to as “blood flow autoregulation”) initially received little attention. More strikingly, even the findings of August Krogh, for which he received the Nobel Prize in Medicine in 1920 (for his discovery of the mechanisms of capillary motor regulation), were ignored. During an outstanding autoregulation symposium held in 1963 a broad consensus was reached on active and passive mechanisms, which is more or less valid till today. The mechanisms of regulation of capillary blood flow are now largely understood, although not completely resolved. The development of video systems with recording capability and automated off-line recording of capillary erythrocyte velocities allowed the application of morphological and dynamic studies of cutaneous capillaries in humans. These reopened the field of physiological or pathophysiological questions again for many groups worldwide. Since 1955, many publications on “microcirculation (5423)” and “capillary microscopy (2195)” have been listed in pubmed.
GDPR compliance through standard security controls: An automated approach
Authors: Granata Daniele , Mastroianni Michele , Rak Massimiliano , Cantiello Pasquale , Salzillo Giovanni
Published: February 2024

Since 2018, the enactment of the General Data Protection Regulation (GDPR) has bestowed distinct privileges upon each person while imposing protocols to safeguard personal information. The GDPR effectively tackles an evident requirement within our interconnected, social media-driven society. However, its compliance poses a considerable challenge, particularly for small and medium-sized businesses. This work aims to identify and select the proper countermeasures in order to comply with GDPR, by using standard security controls. Thus, we designed a tool to handle some phases of the compliance process in an almost semi-automated way. The proposed approach relies on standard security control frameworks (namely NIST SP-800-53) and can be easily adapted to different frameworks. The proposed technique was validated using our university as a case study, through a simple demonstrator, although the solution can be transparently applied to different contexts.
A Novel Constructing Continuous and Topology Approach to Fuzzy β-covering
Authors: He Hongxuan , Wang Pei , Lu Jiakuan
Published: February 2024

Fuzzy β-covering(Fβ-C) plays a key role in processing real-valued data sets and covering plays an important role in the topological spaces. Thus they have attracted much attention. But the relationship between Fβ-C and topology has not been studied. This inspires the research of Fβ-C from the perspective of topology. In this paper, we construct Fβ-C rough continuous and homeomorphism mappings by using Fβ-C operator. We not only obtain some equivalent descriptions of the mappings but also profoundly reveal the relationship of two Fβ-C approximation spaces. We give the classification method of Fβ-C approximation spaces with the help of homeomorphism mapping, propose a new method to construct topology induced by Fβ-C operator and investigate the properties in the topological spaces further. Finally, we obtain the necessary and sufficient conditions for Fβ-C operators to be topological closure operators.

Authors: Yang Lei , Li Deqing , Zeng Wenyi , Ma Rong , Xu Zeshui , Yu Xianchuan
Published: February 2024

Pythagorean fuzzy sets, as a generalization of intuitionistic fuzzy sets, have a wide range of applications in many fields including image recognition, data mining, decision making, etc. However, there is little research on clustering algorithms of Pythagorean fuzzy sets. In this paper, a novel clustering idea under Pythagorean fuzzy environment is presented. Firstly, the concept of feature vector of Pythagorean fuzzy number (PFN) is presented by taking into account five parameters of PFN, and some new methods to compute the similarity measure of PFNs by applying the feature vector are proposed. Furthermore, a fuzzy similarity matrix by utilizing similarity measure of PFNs is established. Later, the fuzzy similarity matrix is transformed into a fuzzy equivalent matrix which is utilized to establish a novel Pythagorean fuzzy clustering algorithm. Based on the proposed clustering algorithm, a novel multiple attribute decision making (MADM) method under Pythagorean fuzzy environment is presented. To illustrate the effectiveness and feasibility of the proposed technique, an application example is offered.
A model for visual evacuation of people considering the effects of gravity
Authors: Yuan Weijin , Deng Yunfeng
Published: February 2024

This paper improves the visual change-based personnel evacuation model by considering the evacuees’ gravity. Specifically, first, the new model incorporates the gravity formula in the model’s mechanic part to consider the influence of gravity. Second, the new model involves rules for determining the visual range of personnel moving in the stairwell. Third, the proposed model investigates the influence of the angle and width of the stairwell, the number of people, and other factors during personnel evacuation under the influence of gravity. The model is developed in Python and is compared with actual results, revealing that the proposed model is more realistic considering the evacuation time compared to current models. Indeed, under a fixed number of people, when the stairwell angle is less than 34°, the evacuation time decreases as the angle increases, and when the stairwell angle exceeds 34°, the evacuation time is almost unchanged. Additionally, under a fixed number of evacuees, the evacuation time decreases as the width of the stairwell increases, and due to stairwell width space redundancy, the evacuation time tends to stabilize. The results of the new model research provide reference for the design of building safety evacuation, thereby improving the safety of buildings.
ADAPT: Attack detection and prevention via deep learning techniques
Authors: Mohan M. , Tamizhazhagan V. , Balaji S.
Published: February 2024

Cloud computing is a new technology that provides services to customers anywhere, anytime, under varying conditions and managed by a third-party cloud provider. Even though cloud computing has progressed a lot, some attacks still happen. The recent anomalous and signature attacks use clever strategies such as low-rate attacks and attacking as an authenticated user. In this paper, a novel Attack Detection and Prevention (ADAPT) method is proposed to overcome this issue. The proposed system consists of three stages. An Intrusion Detection System is initially used to check whether there is an attack or not by comparing the IP address in the Blacklist IP Database. If an attack occurs, the IP address will be added to the Blacklist IP database and blocked. The second stage uses Bi-directional LSTM and Bi-directional GRU to check the anomalous and signature attack. In the third stage, classified output is sent to reinforcement learning, if any attack occurs the IP address is added to the blacklist IP database otherwise the packets are forwarded to the user. The proposed ADAPT technique achieves a higher accuracy range than existing techniques.
Optimizing feature selection and parameter tuning for breast cancer detection using hybrid GAHBA-DNN framework
Authors: Kamala Devi K. , Raja Sekar J.
Published: February 2024

Breast cancer has been life-threatening for many years as it is the common cause of fatality among women. The challenges of screening such tumors through manual approaches can be overcome by computer-aided diagnosis, which aids radiologists in making precise decisions. The selection of significant features is crucial for the estimation of prediction accuracy. This work proposes a hybrid Genetic Algorithm (GA) and Honey Badger Algorithm (HBA) based Deep Neural Network (DNN), HGAHBA-DNN for the concurrent optimal features selection and parameter optimization; further, the optimal features and parameters extracted are fed into the DNN for the prediction of the breast cancer. It fuses the benefits of HBA with parallel processing and efficient feedback with GA’s excellent global convergent rate during the processing stages. The aforementioned method is evaluated on the Wisconsin Original Breast Cancer (WOBC), Wisconsin Diagnostic Breast Cancer (WDBC), and the Surveillance, Epidemiology, and End Results (SEER) datasets. Subsequently, the performance is validated using several metrics like accuracy, precision, Recall, and F1-score. The experimental result shows that HGAHBA-DNN obtains accuracy of 99.42%, 99.84%, and 92.44% for the WOBC, WDBC, and SEER datasets respectively, which is much superior to the other state-of-the-art methods.
Research of news text classification method based on hierarchical semantics and prior correction
Authors: Sun Ping , Song LinLin , Yuan Ling , Yu Haiping , Wei Yinzhen
Published: February 2024

News text is an important branch of natural language processing. Compared to ordinary texts, news text has significant economic and scientific value. The characteristics of news text include structural hierarchy, diverse label categories, and limited high-quality annotation samples. Many machine learning and deep learning methods exist to analyze various forms of news text. However, due to label imbalance, hierarchical semantics, and confusing labels, current methods have limitations. Therefore, this paper proposes a news text classification framework based on hierarchical semantics and prior correction (HSPC). Firstly, data augmentation is used to enhance the diversity of the training set and adversarial learning is employed to improve the resistance of the model with its robustness. Then, a hierarchical feature extraction approach is employed to extract semantic features from different levels of news texts. Consequentially, a feature fusion method is designed to allow the model to focus on relevant hierarchical semantics for label classification. Finally, highly confusing label predictions are corrected to optimize the label prediction of the model and improve confidence. Multiple experiments are performed on four widely used public datasets. The experimental results indicate that HSPC achieves higher classification accuracy compared to other models. On the FCT, AGNews, THUCNews, and Ohsumed datasets, HSPC improves the accuracy by 1.03%, 1.38%, 2.55%, and 1.15%, respectively, compared to state-of-the-art methods. This validates the rationality and effectiveness of the designed mechanisms.
From recession to pandemic: Displacement among workers with disabilities from 2007 through 2021
Authors: Maroto Michelle , Pettinicchio David
Published: February 2024

BACKGROUND: With at least one-quarter of the U.S. adult population reporting one or more disabilities in 2020, people with disabilities represent a large and diverse group of individuals who often face significant barriers in the labor market, especially job displacement - involuntary job loss due to external factors. OBJECTIVE: We examine how rates of job displacement varied for people with different types of disabilities from 2007–2021, a period that includes the 2008 Great Recession and the COVID-19 pandemic. METHODS: We use data from six waves of Current Population Study Displaced Worker Supplement (CPS DWS, N = 344,729) and a series of logistic regression models to examine differences in displacement by disability status and type. RESULTS: People with disabilities were approximately twice as likely as those without disabilities to experience job displacement, but more during times of economic turmoil. Although displacement disparities by disability status were decreasing from a high of 6.5 percentage points during the Great Recession, the pandemic increased the gap to 5.8 percentage points. CONCLUSION: Involuntary job loss among people with disabilities is exacerbated by exogenous shocks. We extend work on disability and displacement, incorporating the COVID-19 pandemic in our discussion of explanations of both labor market disadvantage and precarity.

Authors:   Shakarim University of Semey, Khibadullina A.S.
Published: February 2024

The article talks about one of the new directions in the development of modern journalism - art journalism, as well as about the place and development of "film journalism" in providing information within this direction, cinema. Today's film production is available not only in cinemas, but also on TV, tablets and the Internet. Therefore, it is important to take into account the development of modern film production and different methods of studying the film genre, as well as the function of cinema art in the socio-cultural space. The influence of modern technologies on film production is recognized as an urgent issue. In society in general, no one can limit a person's inner spiritual need and taste. As demand grows, the requirements and tasks for teleworking grow. Television equipment is also being developed taking into account the requirements. Since it is impossible to separate the history of television from cinematography, there is a need to consider film journalism from a theoretical and practical point of view. Therefore, it is necessary to know the theoretical foundations of working with information in the development of art journalism as one of the directions of industry journalism, the development of cinematography. It is known that speech in cinema and on television forms the culture of speech in society, so it is important from a practical point of view to pay attention to the use of the possibilities of cinema, theater and new media and consider the way of a comprehensive study of screen culture

Authors: Aniskin A. , Moskalova K. , Vynnykov Yu. , Soldo B.
Published: February 2024

The work presents an analysis of the results of the fill-in condition influence of particle inclination on horizontal silage pressure. Analyzed data were obtained from experiments on a rectangular silo model with rigid walls in a different fill-in condition. The filler was a composite mixture of sand and flat shell particles (2:1). The analysis of the results concluded that the volume weight of the composite mixture depends on the fill-in method, which affects the horizontal silage pressures. At filling of 0° and 45°, the pressure is slightly different from Jansen's theory (max 19%) which can be neglectable. Horizontal silage pressures are functionally dependent on the filling method (up to 44%), which should definitely be taken into account.

Published: February 2024

With the rapid development of nanotechnology, the need to improve the efficiency of material grinding processes has increased. One of the criteria for the effectiveness of the process is the product fineness. There are various types of mills for grinding materials, one of which is stirred media mills. The article presents the results of experimental studies of a new design of stirred media mill on the example of sand particles size reduction. The principle of operation of the new mill is based on the organization of complex radial and axial impact on the particles of the material by grinding balls. To ensure this principle, a typical stirred media mill design includes an ellipsoidal rotor and a vibratory drive with springs. The results of the study demonstrated that the maximal product fineness of the mill with an initial sand particle size of 100 µm accounted for 2.32 µm, which is 2.6 times higher than the product fineness obtained in typical stirred media mill designs.

В результате расчета контактного давления между колесами и железными дорогами максимальное контактное давление было на уровне 534 МПа, и это можно сравнить с данными в справочнике «контактное давление и срок службы», где кривая зависимости контактного давления от циклов показывает 104 миллиона циклов на уровне контактного давления ниже среднего балла 1. Исходя из данных в справочнике, хотя нарушения усталости из-за износа не ожидаются при уровне контактного давления 534 МПа, нарушения усталости в зоне контакта зависят от состояния поверхности и внешних условий, поэтому было решено, что смазка и техническое обслуживание поверхности должны проводиться регулярно.

Логистика онлайн-торговли - одна из важнейших составляющих интернет-магазина, но логистические расходы продолжают расти с каждым годом. Рост онлайн-продаж увеличивает спрос и ограничивает доступность логистической инфраструктуры, поскольку ужесточение нормативных требований, повышение заработной платы и нехватка сотрудников также приводят к росту цен. В статье рассматриваются вопросы методики совершенствования логистического процесса компании, действующая на рынке электронной коммерции, как Lamoda, Wildberries, Leroy Merlin. Исследование проведено в рамках проекта [1]. Для достижения поставленной цели было проведено исследование особенностей и тенденций казахстанского и зарубежного рынка электронной коммерции; проанализирована логистическая деятельность интернет-магазина; проведено исследование логистической деятельности компании с помощью таких инструментов анализа, как хронометраж, диаграмма Исикавы, SWOT-анализ, анкетирование клиентов;  выявлены основные логистические проблемы интернет-магазина; разработаны пути улучшения логистической деятельности интернет-магазина. Системный метод исследования цепей поставок и особенностей их цифровой трансформации в процессе перехода к интернет-торговле включает анализ и синтез эмпирической базы исследования. Рассмотрены логистические процессы e-commerce, сформулированы основные подходы к совершенствованию логистики интернет-магазина. Быстрое развитие электронной торговли приводит к таким серьезным последствиям для логистики, как расширение экстернализации, т.е. передачи отдельных функций по перевозке, оформлению и курьерской доставке заказанных товаров специализированным фирмам, более тщательное управление продвижением товаров к покупателю и их возвратом, увеличение доли экспресс-доставки и ускорение концентрации в торговле и сфере услуг. Изучив работу нескольких крупных компаний как совершающих онлайн-продажи, можно сделать вывод, что рынок электронной коммерции с каждым годом развивается и привлекает все новых пользователей. Данные компании Lamoda, Wildberries, Leroy Merlin улучшают и расширяют предоставляемые услуги, делая уклон на повышение качества обслуживания, расширяют виды платежей и гибкие условия доставки. Учитывая то, что уровень онлайн-покупок в Казахстане является средним, по сравнению со странами дальнего зарубежья, можно сказать, что у рынка электронной коммерции в стране есть большой потенциал в росте данного показателя.
К вопросу определения уровня влагосодержания в трансформаторном масле
Authors: Рахимов Р.В.
Published: February 2024

Автором в данной статье рассматривается вопрос регенерации трансформаторного масла в лабораторных условиях с применением ротационного испарителя. Цель исследования состоит в повышении электроизоляционных свойств методом удаления излишнего количества влаги из состава масла. Ротационный испаритель, работая при пониженном давлении, нагревая масло, удаляет содержащуюся в виде осадка или эмульсии влагу, тем самым повышая электроизоляционные свойства масла и снижая его окислительные свойства. Испытание носит лабораторный характер и имеет вес испытуемого образца 1 киллограмм. В процессе испытаний был использован ротационный испаритель Heidolph серии Hei-VAP Precision 2018 года выпуска (Германия). Испытание образца проводилось на базе дорожной лаборатории научно-производственного центра «ENU-Lab», созданной в рамках государственной программы индустриально-инновационного развития Республики Казахстан. Были получены основные результаты, а именно: количество выделенной влаги (W) в процентах за счет разницы массы до и после испытания образца. Полученные результаты были сопоставлены с требованиями действующей на территории Республики Казахстан нормативно-технической документации. Сравнительные данные позволяют сделать выводы о необходимости снижения влагосодержания из состава поставляемого на рынок трансформаторного масла, путем применения ротационного испарителя в виде основного инструмента для достижения этой цели.  Результаты могут быть использованы в практических целях с созданием установок промышленного масштаба. Также с помощью полученных результатов есть возможность обозначить необходимость внедрения данной технологии, в виде дополнительной, на ныне существующих заводах по производству трансформаторного масла.

Published: February 2024

The leading place in the technology of modern mechanical engineering production is occupied by cutting processes. In many branches of mechanical engineering, especially in mass production, their labor and production costs reach 40-60% of the total costs of metalworking. Nowadays, no more or less complex machine can be made without the use of cutting tools. Thus, we can rightfully assert that cutting machining has retained its predominant influence on the development of mechanical engineering technology and its importance will be steadily increasing in the future, largely based on the use of fundamentally new machining methods. And the latter can be rightly attributed to the so-called rotary cutting. The authors have developed a design of a special multi-blade rotary-friction tool for machining cylindrical surfaces of parts made of hard-to-machine materials. This paper presents the results of the calculation of the most loaded node of the multi-blade rotary-friction tool of the part “shaft”. Calculation of the bending strength of the shaft has been performed. The results of the calculation have been checked through the program Apm Winmachine which has confirmed their correctness. This research is funded by the Ministry of Science and Higher Education of the Republic of Kazakhstan (Grant No. AP14972884).

В статье рассмотрены вопросы  внедрения повышения эффективности  транспортировки  высоковязкой  нефти  по магистральным  нефтепроводам Республики Казахстан путем  внедрения   теплонасосной   технологии  ее подогрева с использованием  нетрадиционных  источников энергии. Впервые  предложена  к  практическому внедрению на объектах АО «НК «КазМунайГаз» (далее – АО «КМГ») конкретная технология и схема  применения  низкоуглеродного  модульного  теплонасосного  комплекса (НМТК) подогрева  сырой  нефти  с  использованием  сбросной теплоты  воды с температурой  +110С, отделенной после сепарации  нефте-водяной эмульсии, выкачиваемой из скважин. В качестве пилотной площадки для проведения опытно-промышленных испытаний (далее – ОПИ) предварительно рассматривается НГДУ «Жайыкмунайгаз» месторождение Ю.З. Камышитовое с 2-х ступенчатой схемой подогрева нефти. При проведении ОПИ планируется установить модуль с тепловым насосом (НМТК) на узле подогрева нефти, тем самым снизить нагрузку на технологических печах, что в итоге существенно снизит потребление топливного газа. Данная инициатива  является инновационной и впервые предусматривает использование тепловых насосов в процессе подогрева нефти в Республике Казахстан. Перспективы применения НМТК – в тиражировании данной технологии на другие добычные активы АО «НК «КазМунайГаз».

Благодаря своей исключительной прочности и долговечности железобетон давно стал основным материалом для строительства. Одним из ключевых компонентов железобетонных конструкций является стальная арматура, которая обеспечивает прочность на растяжение, противодействуя слабости бетона при растяжении. Однако последние инновации привели к поиску альтернативных материалов, способных повысить эксплуатационные характеристики железобетонных элементов. Среди них значительное внимание привлекает использование фиброармированных пластиков. В статье представлены данные по применению новых типов фиброармированных пластиков для усиления железобетонных конструкций. Результаты исследования способствуют сокращению сроков выполнения работ, также отсутствие дополнительных конструктивных элементов от усиления несущих конструкций,   не изменяет существующую полезную площадь усиливаемого объекта.
Crime in the law enforcement agencies in 1948–1952 and its counteraction
Authors: Grechenko V. A.
Published: February 2024

The article reveals the state of crime in the police in 1948–1952, identifies its main manifestations and measures to counteract it. Crime in the police in the post-war years remained an acute and permanent problem. The late 1940s and early 1950s were no exception. This was influenced by the very nature of the totalitarian regime, which was based on violence and violation of the rule of law, the difficult socio-economic situation in the country, as the consequences of the post-war devastation were only beginning to be eliminated, and the low level of professional training and education of a certain number of police officers. For many of them, the perceptions of the state of legality were quite specific, formed mainly under the influence of the events of the war, combined with a tendency to be quick to punish those who were considered criminals and a relatively low level of awareness of the law. All of this has led to the existence of the problem of crime in the law enforcement agencies of the republic, and this problem is still relevant today, both from a theoretical and practical point of view. The most common violations in the police at that time were: alcoholism, abuse of office, connections with criminals, violations of the law during the detention of citizens and the conduct of investigations, failure to comply with orders, bribery, embezzlement, domestic and moral decay, desertion, disclosure of official secrets, unauthorised abandonment of duty, illegal use of weapons and, as a result, injury or killing of citizens, negligence in the performance of official duties, and loss of personal weapons. Most cases of lawbreaking were committed by police officers who were intoxicated. During this period, the Ministry of Internal Affairs of the Ukrainian SSR took a number of measures to improve the situation: offenders were dismissed from the police and brought to trial, and the leadership of those local police forces with the highest number of such violations was changed. This was done on the basis of an analysis of the flow of investigative cases, inspection of documentation and the state of work of local police bodies in the field of training their personnel.
Essence of contracts concluded for implementing corporate investment
Authors: Kukhariev O. Ye.
Published: February 2024

The article is focused on clarifying the essence of contracts in the field of corporate investment. Achieving the specified purpose is realized through the analysis of the relevant norms of the current legislation of Ukraine, court case-law and provisions of the legal doctrine, which is the objective of this article.

It has been emphasized that investment contracts cover various types of civil contracts. It has been determined by the subject matter and objectives of investment (joint operation agreements, capital construction contracts, credit granting agreements, purchase and sale agreements, fiduciary management agreements).

The contract is the main form of investing in the field of corporate legal relations. The author has substantiated the specific features of such a contract, which are: the special sphere of its application; special contracting parties.

The sphere of application of the contracts studied in the article is corporate legal relations, that is, relations connected to the exercise of corporate rights to participate in the management of a business entity. The parties to the contract in the field of corporate investment are the subjects of investment operation, which primarily include: an investor, i.e., the subject of investment operation that makes a decision to invest own, loaned and borrowed property and intellectual values into investment objects. The other party to the contract can be, in particular, a corporate fund, assets management company as recipients of investments.

Such contracts are not united by a common subject matter, which is determined by a specific type of investment contract (asset management actions, a share in the authorized (joint) capital of a business entity, etc.). Therefore, the author has emphasized the impracticality of uniting contracts in the field of corporate investment into a separate group of civil contracts. Contracts concluded for the purpose of implementing corporate investment are consensual, commutative and bilateral.
