Human Rights in Science: Observations From Ethics Committees on Medical Research Protocols
Authors: Vasco-Morales Santiago , Vasco-Toapanta Cristhian , Guanoluisa-Vasco Alisson , Vasco-Toapanta Gabriel , Toapanta-Pinta Paola
Published: September 2024

Objective: To determine the frequency with which Research Ethics Committees (RECs) identify breaches of ethical principles in research protocols.
 
Theoretical Framework: Ethical principles in human research are established in the Nuremberg Code (informed consent and the common good), the Declaration of Helsinki (protection of vulnerable groups), and the Belmont Report (autonomy, beneficence, and justice). These principles are monitored by RECs to protect participants and ensure fairness in resource use. Informed consent ensures autonomy and the integrity of the research.
 
Method: Searches were conducted in PubMed, Scopus, and Google Scholar up to November 30, 2023. A meta-analysis of single proportions was performed. PROSPERO Registration: CRD42021291893
 
Results and Discussion: Nine publications were reviewed, revealing violations of the principle of justice in up to 100% of protocols. In Latin America, violations were observed in 9% (95% CI: 7-12) of protocols, while in Europe, the rate was 15% (95% CI: 9-24). Autonomy was observed in 26% (95% CI: 20-33) of protocols, with 17% (95% CI: 13-22) in experimental studies. Observations on beneficence varied between 41.17% and 77.38%. Protocol-specific observations ranged between 5.26% and 27.11%, showing regional disparities among study types. RECs must ensure thorough evaluations to uphold autonomy and maximize benefits for participants.
 
Research Implications: Provide a foundation for future investigations on the work of  RECs, the implementation of ethical principles, and equity in research.
 
Originality/Value: The publication of observations on ethical principles made by the Research Ethics Committees is essential for drafting new research protocols.

For free vibration analysis of rod systems formulation of the finite element force method with extended shape functions obtained by using the mode shapes of a fixed-fixed rod is proposed. Examples illustrating the accuracy of numerical solutions for three types of finite elements are given. The use of proposed approach for the space frame gave differences between numerical solutions dealt with 8 finite elements and exact results less than 5% for the first five natural frequencies.

Для анализа свободных колебаний стержневых систем предложена формулировка метода конечных элементов в усилиях с расширенными функциями формы, полученными с использованием форм колебаний неподвижно закрепленного стержня. Приведены примеры, иллюстрирующие точность численного решения для трех типов конечных элементов. Использование предложенного подхода для пространственной рамы дало различия между численными решениями для восьми конечных элементов и точными результатами менее 5% для первых пяти собственных частот.

Immunodeficiency: Burden of Illness
Authors: Hsueh Justin C. , Van Hersh Andrew T. , Zhao Wei
Published: September 2024

Immunodeficiency disorders pose substantial burdens on the health-care system and the patients affected. Broadly, immunodeficiencies can be divided into primary immunodeficiency disorders (PIDDs) and secondary immunodeficiency disorders. This review will focus on PIDDs. The overall
prevalence for PIDDs is estimated to be ∼1‐2% of the population but may be underestimated due to underdiagnosis of these conditions. PIDDs affect males slightly more often than females. The mortality rates differ based on the specific condition but can be extremely high if the condition
is left undiagnosed or untreated. The most common causes of death are infections, respiratory complications, and cancers (e.g., lymphoma). Comorbidities and complications include infection, chronic lung disease, granulomatous lymphocytic interstitial lung disease, and autoimmune disorders.
The disease burden of patients with common variable immunodeficiency (CVID) is estimated to be greater than patients with diabetes mellitus and chronic obstructive pulmonary disease. PIDDs have a serious impact on the quality of life of the patients, including sleep disturbance, anxiety, and
social participation as well as other psychosocial burdens associated with these disorders. The financial cost of PIDDs can be substantial, with the cost of untreated CVID estimated to be $111,053 per patient per year. Indirect costs include productivity loss and time lost due to infusion
and hospital visits. Secondary immunodeficiency is not fully discussed in this review but likely contributes equally to the burden of overall immunodeficiency disorders. Management of patients with PIDDs should use a comprehensive approach, including medical, nursing, psychiatric, and quality
of life, to improve the outcome.

The focus of this research is on the strategies for preserving Seudati dance by the Pidie Jaya government in the era of disruption. Pidie Jaya is one of the regencies known for the Seudati dance, and many prominent Seudati leaders, known as "syeh," hail from this region. This research was conducted in Pidie Jaya Regency, with the location chosen due to the observed phenomenon that the youth are no longer interested in learning and performing Seudati. Data collection techniques in this research included participant observation, where the researcher directly observed the subjects to gather data. In addition to participant observation, in-depth interviews were also employed as a technique for collecting data. The results of the research indicate that the youth are abandoning Seudati because the digital world is more appealing than Seudati. Furthermore, learning Seudati is not as easy as learning other dances. In response to these challenges, the Pidie Jaya government has made efforts to preserve Seudati through several approaches. First, they utilize digital media itself as a platform for Seudati campaigns. They also give recognition to Seudati maestros, creating a positive impression for all parties involved. The government promotes Seudati in extracurricular activities through the Gerakan Seniman Masuk Sekolah. Additionally, they are reactivating village dance studios and providing spaces for expression, such as the Pekan Kebudayaan Pidie Jaya.

Menangkap ikan adalah mata pencarian yang ditekuni setiap hari oleh masyarakat pesisir pantai Katapiang Padang Pariaman Sumbar. Biasanya, nelayan menangkap ikan di tengah laut dan hasil tangkapan dibawa dengan perahu kedarat. Setelah perahu sampai dibibir pantai kemudian perahu yang berisi hasil tangkapan ikan di tarik ke darat bersama sama oleh kelompok nelayan secara manual menggunakan tenaga manusia. Proses tersebut menurut nelayan tidak efektif dan meminimalkan hasil tangkapan karena harus dibagi ke anggota penarik. Adapun tersedia alat penarik sederhana tetapi tidak layak pakai karena tidak terawat dengan baik. Tujuan pengabdian pada masyarakat ini adalah mengedukasi masyarakat tentang alat bantu penarik perahu melalui pelatihan singkat tentang alat penarik perahu, cara operasi dan perawatannya supaya alat dapat berfungsi dengan baik dan memiliki umur pakai yang lama. Metoda yang digunakan adalah metoda pelatihan langsung ke kelompok Nelayan mitra. Hasil yang didapat setelah pelatihan ini anggota kelompok nelayan mampu mengoperasikan alat penarik kapal dan mampu melakukan perawatan harian pada alat penarik perahu.

ABSTRACT
Fishing is the daily livelihood of the coastal community in Katapiang, Padang Pariaman, West Sumatra. Typically, fishermen catch fish in the open sea and bring their catch to shore by boat. Once the boat reaches the beach, the fishermen manually pull the boat, filled with their catch, to shore together as a group. This manual process is considered inefficient by the fishermen, as it reduces their catch since it has to be divided among the pullers. Although there is a simple pulling device available, it is not in usable condition due to poor maintenance. The aim of this community service is to educate the community about the boat pulling device through a brief training session on its operation and maintenance, ensuring the device functions properly and has a longer lifespan. The method used is direct training for the partner fishermen group. The outcome of this training is that members of the fishermen group are able to operate the boat pulling device and perform daily maintenance on it.

ABSTRACT
Virgin coconut oil (VCO) is often unfamiliar to the general public, even though VCO has various benefits for health and economic development. Community service in the form of training in making virgin coconut oil (VCO) is carried out to assist the community in processing coconut, which produces products to improve health and community skills. This community service activity is carried out to prevent diseases that generally occur in the community, such as cholesterol obesity, and develop community skills in processing coconut into products with high economic value. Based on the research results, VCO has good properties to increase the body's immunity and prevent obesity and cholesterol. In addition, the easy availability of coconut makes this a good potential to be developed as a community economic empowerment. The training and socialization of VCO production was conducted in Cilembang Village, Cihideung District, Tasikmalaya City, West Java. As a result of this VCO-making training, the community is very enthusiastic to gain new knowledge and valuable skills about processing coconut into health products in the form of VCO and high-value products for community economic development.

We study the question of how a local learning algorithm, executed by multiple distributed agents, can lead to a global system of communication. First, the notion of a perfect communication system is defined. Next, two measures of communication system quality are specified. It is shown that maximization of these measures leads to perfect communication production. Based on this principle, local adaptation rules for communication development are constructed. The resulting stochastic algorithm is validated in computational experiments. Empirical analysis indicates that a mild degree of stochasticity is instrumental in reaching states that correspond to accurate communication.
From Collective Mind to Communication
Authors:   Jet Propulsion Laboratory and California Institute of Technology, Ultra-computing Group Pasadena, CA 91109, Zak Michail
Published: September 2024

"Collective mind" is introduced as a set of simple intelligent units (say, neurons, or interacting agents) that can communicate by exchanging information without explicit global control. Incomplete information is compensated for by a sequence of random guesses symmetrically distributed around expectations with prescribed variances. Both the expectations and variances are the invariants characterizing the whole class of agents. These invariants are stored as parameters of the collective mind, while they contribute to dynamical formalism of the agents' evolution, and in particular, to the reflective chains of their nested abstract images of the selves and nonselves. The proposed model consists of the system of stochastic differential equations in the Langevin form to represent motor dynamics, and the corresponding Fokker-Planck equation to represent mental dynamics. The main departure of this model from newtonian and statistical physics is due to feedback from the mental to the motor dynamics, which makes the Fokker-Planck equation nonlinear. Interpretations of this model from mathematical, physical, biological, and psychological viewpoints are discussed. The model is illustrated by the dynamics of a dialog.

Published: September 2024

The use of swarm clustering algorithms is investigated in the design of simple robots capable of carrying out swarm-mediated construction. Methods for generating multiple clusters of predetermined size are developed. Relative cluster motion algorithms are also developed and explored. All robotic algorithms are predicated on the use of robots that utilize no processing, global positioning, or explicit communication. Simple stigmergic communication and minimal sensing capabilities are used exclusively. Swarms of minimal agents are used to build equilateral triangles, squares, and pentagons. Future use of these methods in the design of more sophisticated construction techniques is discussed.

Published: September 2024

This paper investigates some series of integers which are derived from a recursively defined sequence of permutations of words. Such a recursion can be interpreted as a dynamic system. Geometrical representations of these series appear to be self-similar, symmetrical, and factorizable. The paper also shows how some bidimensional images may be decomposed into images corresponding to permutations of fewer symbols.
A Note on the Game of Life in Hexagonal and Pentagonal Tessellations
Authors:   Department of Computer Science and Engineering, University of South Carolina, Columbia, SC, Bays Carter
Published: September 2024

Most readers are familiar with cellular automata (CA) utilizing squares as cells, and are also familiar with the most famous automaton, Conway's Game of Life. This game is played on an infinite grid of squares, and has been thoroughly explored in many publications [1, 2] as well as on numerous websites. In 1994 in this journal the author introduced several games of life in the triangular tessellation [3]. It now appears, not surprisingly, that other tessellations also support games of life.
Dynamics of the Cellular Automaton Rule 142
Authors:   Electronic mail address: hfuks@brocku.ca Department of Mathematics, Brock University, St. Catharines, Ontario L2S 3A1, Canada, Fukś Henryk
Published: September 2024

We investigate dynamics of the cellular automaton Rule 142. This rule possesses additive invariant of the second order, namely it conserves the number of blocks "10." Rule 142 can be alternatively described as an operation on a binary string in which we simultaneously flip all symbols which have dissenting right neighbors. We show that the probability of having a dissenting neighbor can be computed exactly using the fact that the surjective Rule 60 transforms Rule 142 into Rule 226. We also demonstrate that the conservation of the number of 10 blocks implies that these blocks move with speed -1 or stay in the same place, depending on the state of the preceding site. At the density of blocks 10 equal to 0.25, Rule 142 exhibits a phenomenon similar to the jamming transitions occurring in discrete models of traffic flow.
Estimating Transient Surface Heating using a Cellular Automaton Energy-transport Model
Authors:   College of Engineering, Temple University, 1947 North Twelfth Street, Philadelphia, PA 19122 USA, Peridier Vallorie J.
Published: September 2024

The use of subsurface temperature data to estimate an unknown transient surface-heating event is a classic, and practical, inverse problem in engineering. This paper describes a new inverse heat-transfer estimation procedure that is formulated using a cellular automaton model of energy transport into the medium. The quantitative heat-flux estimates generated by this new scheme appear to have accuracies comparable to conventional inverse procedures; consequently, this new method may prove a useful alternative and/or confirmational strategy in measurement situations where the data is noise-ridden or the heating event is sporadic.

We call "time-out" a software entity that postpones a function call by a given amount of time expressed as local clock ticks. The subject of this paper is a simple software system managing lists of time-outs. We briefly describe that system and discuss its dynamics. We show some experimental results that prove the emergence of complex behaviors.
Placeholder Substructures I: The Road from NKS to Scale-Free Networks is Paved with Zero-Divisors
Authors:   Electronic mail address: rdemarrais@alum.mit.edu Thothic Technology Partners, P.O. Box 3083, Plymouth, MA 02361, Marrais Robert P. C. de
Published: September 2024

Zero-divisors (ZDs) derived by the Cayley--Dickson process (CDP) from N-dimensional hypercomplex numbers (N a power of 2, and at least 4) can represent singularities and, as N goes to infinity, fractals and thereby, scale-free networks. Any integer less than 8 and not a power of 2 generates a metafractal or sky when it is interpreted as the strut constant (S) of an ensemble of octahedral vertex figures called box-kites (the fundamental ZD building blocks). Remarkably simple bit-manipulation rules or recipes provide tools for transforming one fractal genus into others within the context of Wolfram's Class 4 complexity.

This study examines goal-free viewing of cellular automaton (CA) images to address the nature of the bottom-up process, the robustness of salience as a framework for explaining fixation points, and the particular features that can characterize salience. The influence of familiarity on oculomotor strategy is also addressed. A qualitative study of the results show promising trends. Higher-level structural features such as pockets of regularity within randomness or localized structures within regularity were salient for most participants. These results raise interesting questions about the kinds of visual features that can be used to characterize salience. An unexpected result is that many fixations occur in blank regions within images featuring nested (fractal) structures. Many of these findings escape current psychophysical models of oculomotor strategy. Hence, future eye-tracking studies with CAs as stimuli could greatly improve our current understandings of the human visual system.

Review of Authentication Systems based on Electroencephalogram
Authors: Basher Hamza Asmaa , K. Hasoun Rajaa
Published: September 2024

Traditional authentication methods, such as the use of passwords and fingerprints, are susceptible to the risks of theft, loss, and forgery. However, an innovative and secure alternative exists in the form of electroencephalogram (EEG)-based authentication systems, which operate by measuring distinctive brainwave patterns. This particular review undertakes a comprehensive analysis of the current state of EEG-based authentication, delving into its advantages, challenges, and potential future directions. In doing so, we examine the underlying principles governing the acquisition and processing of EEG signals, explore the various techniques employed for feature extraction and classification, and evaluate the performance of existing systems. Moreover, we emphasize the significant advantages offered by EEG-based authentication, including its exceptional accuracy, capacity for liveness detection, and robust resistance to spoofing attempts. Nevertheless, we must also acknowledge and address the various obstacles that must be overcome to facilitate wider adoption of this authentication method, encompassing concerns relating to hardware affordability, user acceptance, and data privacy. Finally, we outline a series of promising research avenues that can potentially address these challenges and unlock the complete potential of EEG-based authentication, thereby enabling secure and convenient access control across a diverse range of domains.

Objetivo: Analisar a influência da atividade física, na saúde mental dos indivíduos, durante a pandemia da COVID-19. Revisão bibliográfica: O ano de 2020 foi marcado pelo surgimento do vírus SARS-CoV-2, responsável pela pandemia da COVID-19, gerando diversos impactos deletérios para a saúde física e mental, além de causar desdobramentos socioeconômicos negativos. O isolamento social foi instituído para conter a disseminação da doença, contribuindo para a eclosão e/ou agravamento de transtornos mentais, como ansiedade e depressão. A atividade física regular tem sido demonstrada ao longo do tempo como uma importante estratégia para a prevenção de inúmeras doenças. Da mesma forma, durante a pandemia da COVID-19, exerceu possivelmente um papel protetivo na saúde física e mental. Considerações finais: A atividade física é de suma importância para prevenção, manutenção, melhora da saúde física e mental; adicionalmente, fatores como: intensidade e frequência do exercício, sexo, idade, adesão ao isolamento social, autopercepção do estresse e do bem-estar, podem ter influência nos desfechos de saúde mental.

Objetivo: Investigar quais tratamentos não convencionais são utilizados pelos ribeirinhos da Amazônia para tratar feridas por acidentes ofídicos. Métodos: Trata-se de um estudo descritivo, com abordagem quantitativa, realizado nas unidades básicas de saúde de referência a comunidades ribeirinhas em um município do interior do Amazonas. Para obtenção dos dados, realizou-se a coleta de informações de forma direta, por meio de entrevistas semiestruturadas. Foram selecionados todos os indivíduos que, em algum momento, buscaram atendimento para o tratamento de lesões por acidente ofídico, desde que fossem moradores de comunidades ribeirinhas das proximidades. Resultados: Foram entrevistadas 40 pessoas, sendo a faixa etária de 40 e 49 anos (32,5%) com maior predomínio e maior parte vítimas do sexo masculino (67,5%). Plantas na forma de chá, maceradas, compressas, zooterapia e outros produtos foram utilizados pelos participantes para tratamento do acidente ofídico. Conclusão: Conclui-se que questões socioeconômicas e geográficas contribuem para a falta de atendimento médico imediato dessas populações, sendo a utilização de práticas populares quando ocorre o acidente ofídico não apenas uma tradição, mas, muitas vezes o único recurso utilizado nessas situações.

Проведен анализ действующего электрооборудования слипа и отмечены его недостатки. В целях модернизации обоснована возможность применения асинхронного двигателя с двумя комплектами статорных обмоток для создания многодвигательного электропривода судоподъемного комплекса типа слип. Предложена схема системы согласованных по скорости вращения двигателей. В процессе работы возникают различия параметров между отдельными электроприводами, что приводит к появлению дополнительных ошибок. Предложено провести идентификацию основных параметров и с помощью корректирующих цепей устранить возникшие ошибки. На основе описания элементов системы управления была составлена модель электропривода и проведен анализ возможности коррекции статической и динамической ошибок при рассогласовании параметров электроприводов. Получен график переходного процесса при включении цепи коррекции ошибки. С учетом случайного характера появления рассматриваемой ошибки определено влияние различия параметров на величину дисперсии сигнала.

The analysis of the existing electrical equipment slip and its drawbacks are noted. In order to modernize, the possibility of using an asynchronous engine with two sets of stator windings to create a multimotor electric sliptype shipraising complex is substantiated. The proposed scheme of the system agreed on the speed of rotation of the engines. In the process, there are differences in the parameters between the individual electric drives, which leads to the appearance of additional errors. It was proposed to identify the main parameters and eliminate the errors with the help of correction circuits. A model of the electric drive was compiled based on the description of the elements of the control system. Also an analysis was made of the possibility of correcting static and dynamic errors in the mismatch of the parameters of the electric drives. A transient graph is obtained when the error correction circuit is turned on. Taking into account the random nature of the occurrence of the considered error, the effect of the difference in parameters on the magnitude of the signal dispersion is determined.

В данной статье описаны параметры построения экспертной системы на основе нейросетевых моделей в облачном сервисе для оптимизации методики построения экспертных нейронных сетей с удаленным ядром обработки. Актуальность данной разработки связана с тем, что одной из основных проблем обработки больших объемов социологических данных является невозможность работы с несколькими источниками данных. Использование экспертного ядра как основы разработки требует интеллектуализации информационной системы для недопущения ввода некорректных и нерелевантных данных. В связи с этим проектирование нейронной сети как основы искусственного интеллекта для решения поставленной задачи может быть реализовано на основе облачных технологий с учетом функционирования ядра управляющей системы. Реализация и обоснование данной концепции описано в статье.

This article describes the parameters of building an expert system based on neural network models in the cloud service to optimize the methodology for building expert neural networks with remote processing core. The relevance of this development is due to the fact that one of the main problems of processing large amounts of sociological data is the inability to work with multiple data sources. The use of the expert core as the basis of development requires the intellectualization of the information system to prevent the input of incorrect and non-valuable data. In this regard, the design of the neural network as the basis of artificial intelligence to solve the problem can be implemented on the basis of cloud technology, taking into account the functioning of the core of the control system. The implementation and justification of this concept is described in the article.

Развитие средств автоматизации и микроконтроллерной техники делает возможным программную реализацию и промышленное применение сложных алгоритмов управления. Однако применение алгоритмов управления, отличающихся от классических ПИ/ПИД алгоритмов, не получило широкого распространения. А ПИД алгоритм, как любой алгоритм с обратной связью, при воздействии возмущающего воздействия реагирует по факту отклонения, что снижает качество компенсации. В данной работе решается задача проектирования предиктивного регулятора для компенсации технологических возмущающих воздействий объектов типа нагревательная печь . Описан процесс проектирования нечеткой системы, продемонстрированы результаты сравнительного моделирования. Применение разработанного в работе нечеткого предиктивного настройщика позволяет повысить качество компенсации технологического возмущения вида межзонное влияние в сравнении с ПИрегулятором, настроенным на компенсацию возмущения. Амплитуда ошибки снижена в среднем на 64 в сравнении с ПИрегулятором, настроенным на переходный процесс, время компенсации сокращено на 21 .

The development of automation facilities and microcontrollers makes possible implementation and industrial application of complex control algorithms. However, the algorithms, which diff er from classical PI / PID control laws, are not widespread. Considering disturbances rejection, the PID algorithm, like any other feedback law, reacts to control error rise, but such transient quality could be improved in case the controller would be able to react earlier. In this research mentioned problem is solved with the help of the proposed predictive controller based on fuzzy logic, which is used to reject technological disturbances acting on such plants as heating furnaces. The process of fuzzy system design is described the results of comparative modeling are shown. Application of the developed fuzzy predictive controller allows to improve the compensation of such disturbance as interzone heat transfer in comparison with a conventional PIcontroller. The amplitude of the control error is reduced by 64 averagely comparing to PIcontroller tuned for transient processes, the transient time is reduced by 21 .
