Pozycja gospodarcza miast Europy Środkowo-Wschodniej na tle świata
Authors: Raźniak Piotr , Nowotnik Dariusz
Published: October 2023

W niniejszej pracy przeanalizowano przychody, dochody, wartość rynkową, wartość środków trwałych i sektory największych firm notowanych na liście Forbes Global 2000 (lata 2006 i 2012). Za pomocą wskaźnika normalizacji przez wartość maksymalną określono ranking miast, w których znajduje się co najmniej jedna siedziba korporacji ze wspomnianej listy. Wykazano, że najwyższymi wartościami cechowały się: Tokio, Nowy Jork, Londyn, Paryż i Pekin. Największą dynamiką wzrostu charakteryzowały się miasta azjatyckie, wśród których zdecydowanie dominował Pekin. Ośrodki umiejscowione w Stanach Zjednoczonych rozwijały się stosunkowo słabo w porównaniu z Tokio, a w przypadku wielu z nich zanotowało spadek badanego wskaźnika. Z kolei spośród miast Europy Środkowo-Wschodniej jedynie Moskwę można zaliczyć do najważniejszych miast świata; pozostałe prezentują stosunkowo niską wartość badanego wskaźnika. Pozytywnym aspektem jest jednak dodatnia dynamika wzrostu, dzięki której kolejne miasta mogą dołączyć do grupy miast liczących się na arenie międzynarodowej. Zauważono także, że miejsce w rankingu głównych miast regionu jest znacznie niższe niż ich powiązań międzynarodowych.

Authors: Moreno-Salazar-Calderón Khiara Aliyah Bet
Published: October 2023

El estudio de los indicadores de exposición, sensibilidad y capacidad adaptativa sobre la vulnerabilidad al cambio climático tiene como finalidad conseguir una mayor comprensión sobre los principales indicadores que repercuten en las comunidades y facilitar a las autoridades responsables implementar acciones de mitigación. El objetivo del estudio fue identificar los principales indicadores de vulnerabilidad al cambio climático en las comunidades pesqueras de la región Tacna. Se consideró una muestra de 255 pescadores artesanales, que se encontraban debidamente registrados en las asociaciones pesqueras ubicadas en el litoral de Tacna, organizados en ocho comunidades pesqueras: Santa Rosa, Los Palos, Yarada Baja, Llostay, Boca del Río, Vila Vila, Morro Sama e Ite. Se utilizó información de fuente primaria a través de la aplicación de un cuestionario conformado por 32 indicadores. Los hallazgos de la presente investigación señalan que el principal indicador es la dependencia de la pesca, por lo que al incrementar la no dependencia de la pesca se reduce el nivel de la vulnerabilidad al cambio climático de estas comunidades; asimismo, que las variables exposición y sensibilidad no influyen sobre la vulnerabilidad y que a mayor capacidad adaptativa disminuye la vulnerabilidad.

Authors: RM Rusman , As’ad Ihwana , Alwi Erick Irawadi
Published: October 2023

Ongoing technological developments have brought progress in the form of online sales applications. This online sales technology is often also referred to as E-Commerce. Services at the Sinar Bukhari Store for resellers who want to buy goods are still manual and simple, the sales process still uses the WhatsApp group, making it difficult for resellers and also for the shop if there are purchases of goods simultaneously. Resellers also have trouble ordering if the admin they contact is inactive, if new items are sent via the WhatsApp group, the old items will be buried in the group, making it difficult for resellers to order items that have been stockpiled. Then the solution to the problem where the E-Bukhary shop application will be made with a website-based business to business (B2B) model uses the application of prototyping techniques which make plans quickly and gradually so that potential users tend to be quickly assessed. In the E-bukhary shop application, there is a shop feature that involves admins and resellers to simplify the sales process according to the items available. through trials using black box testing in terms of interface scale 1-5 the value is 88% with very good assessment criteria, in terms of application performance a score of 88.8% is included, including very good criteria. in terms of the application database, a score of 86.6% was generated which included very good assessment criteria, then on the missing or damaged application function aspect, a value of 90% was produced in very good criteria, the last on the termination aspect resulted in a value of 86.2% or in very good criteria

El foro de necesidad y el acceso internacional a la justicia ante la vulneración de derechos humanos por parte de sujetos económicos privados
Authors: Bardel Daniela , Merino Calle Irene
Published: October 2023

El derecho de acceso a la justicia es uno de los derechos humanos que ha generado un replanteamiento a las ramas jurídicas, entre las que se encuentra el Derecho Internacional Privado. Este trabajo tiene por objetivo exponer cómo el derecho de acceso a la justicia interpela el posicionamiento de esta área, poniendo en agenda la oportunidad de regular el foro de necesidad como ultima ratio para el acceso a la justicia. En especial, esta situación será abordada en la relación de empresas y derechos humanos, es decir, en el vínculo entre la regulación de los sujetos económicos en su actuación transnacional y el respeto a los derechos humanos. Para ello, en primer lugar, analizaremos el acceso a los sistemas judiciales y en particular la situación de las empresas y los derechos humanos; y, en segundo lugar, exploraremos la regulación del forum necessitatis en la Unión Europea y en Latinoamérica, particularizando en el derecho español y argentino. Finalmente, se postula el argumento de pensar la posibilidad del uso estratégico en la regulación del foro de necesidad, y se justifica el instituto con referencia en casos jurisprudenciales.

La regulación como modalidad genérica de intervención pública. La regulación en la sociedad digital (Transformaciones en el derecho público y privado)
Authors: Quadra Salcedo Fernández del Castillo Tomás de la
Published: October 2023

La creciente digitalización de la sociedad actual está dando lugar a problemas nuevos a los que el Derecho tiene que dar respuesta; las técnicas tradicionales silogísticas en las que basta con aplicar una norma clara y precisa a situaciones más o menos simples descritas en la norma no sirven. Ello lleva a aplicar técnicas de regulación utilizadas, hasta ahora, básicamente en el ámbito de la economía. Con las mismas se busca proteger los derechos de las personas en las nuevas situaciones en las que las tecnologías digitales hacen más difícil predeterminar en las normas las conductas permitidas o prohibidas. Se busca proteger también la democracia misma y el funcionamiento de un sistema económico en el que la libre y leal competencia es un elemento esencial.

Las primeras respuestas del Derecho de carácter regulatorio al inevitable proceso de digitalización de la sociedad actual las encontramos en el ámbito de la protección de datos; pero a ellas le están siguiendo las relativas a la inteligencia artificial o a los denominados neuro-derechos, entre otras. Esa extensión de técnicas regulatorias en ámbitos distintos del económico implica una transformación del Derecho. Para empezar del Derecho público al encomendar a autoridades administrativas independientes la vigilancia, supervisión y control en primera instancia del respeto a las reglas y principios en materias tales como la libertad de expresión y opinión, la información, la intimidad, etc, sin olvidar las últimas fronteras de una eventual transparencia de nuestros comportamientos y sentimientos a partir del acceso al sistema neuronal del cerebro. Pero ello afecta también al derecho privado y mercantil en la medida en que aspectos como la identidad, el nombre, la herencia, la publicidad o la comercialización de bienes y servicios queda afectada por la posesión monopólica de datos.

La interferencia de las nuevas autoridades administrativas independientes viene determinada especialmente por la apelación y remisión cada vez más intensa - desde las reglas y principios del Derecho – a ciencias, conocimientos o prácticas ajenas (aliunde) al Derecho, aunque metabolizadas por él. Esa ajenidad es lo que exige acudir a agencias administrativas no integradas solo por juristas, sino por expertos en otras ciencias o conocimientos, que acabarán abriendo el camino y condicionando las respuestas que jueces y magistrados finalmente darán en los procesos y conflictos entre partes que se sometan a su conocimiento.

La Ley aplicable a los contratos del personal civil internacional de las misiones de la Unión Europea. A propósito de la STGUE de 10 de noviembre de 2021
Authors: Crespo Hernández Ana
Published: October 2023

En el caso Jenkinson, el Tribunal General de la Unión Europea resuelve las reclamaciones planteadas por un trabajador irlandés que durante varios años prestó servicios, siempre sobre la base de contratos de duración determinada, para diversas Misiones de la Unión Europea, la última de ellas en Kosovo. Tras la extinción del contrato, el trabajador reclama ante el TGUE que los diferentes contratos temporales se recalifiquen como una única relación laboral indefinida. Aunque cada uno de los contratos, contemplado individualmente, conduce a la aplicación de leyes diferentes, la STGUE de 10 de noviembre de 2021 establece la aplicación del Derecho irlandés a la totalidad de la relación laboral. El caso se analiza teniendo en consideración las especialidades que plantean los contratos suscritos con la Unión Europea desde el punto de vista del Derecho internacional privado.

Authors: Oliveira Eziel Gualberto de , Benini Élcio , Melges Fabio
Published: October 2023

Este trabalho tem o objetivo de investigar como iniciativas de crédito solidário podem promover práticas participativas de organização comunitária que representem processos de desenvolvimento socioeconômico local. Como estratégia de análise do campo empírico, optou-se pelo estudo da experiência do Banco Ita, um Banco Comunitário de Desenvolvimento que atua no Assentamento Itamarati, em uma região rural do município de Ponta Porã, MS. A investigação sobre o objeto de estudo, associada à análise da experiência dos Bancos Comunitários, sustenta que tais organizações apresentam significativas contribuições para a organização de recursos financeiros de caráter associativo, desburocratizando e favorecendo o acesso de baixo custo a serviços de crédito mais adequados às necessidades comunitárias. Nesse sentido, apesar de o desenvolvimento local ser uma alternativa bastante restrita quando articulada apenas dentro de delimitações comunitárias, a mobilização participativa destacou-se como dinâmica estrutural e com potenciais emancipatórios, evidenciando o fortalecimento político de alternativas de resistência contra as forças globais e financeiras da desigualdade.
Da assistência técnica à extensão rural em cooperativas agropecuárias
Authors: Petarly Renata Rauta , Souza Welison Portugal de
Published: October 2023

As cooperativas agropecuárias têm longa experiência na oferta de serviços de assistência técnica para os seus associados. Esta atuação, e as consequências advindas dela, apesar de potencialmente diversa e relevante, não tem sido suficientemente discutida por cooperativas, institutos de pesquisa e empresas que prestam o serviço. Trata-se de uma investigação teórica, que tem por objetivo investigar a questão, baseada nas experiências das cooperativas de Minas Gerais, no Brasil. Dado o contexto competitivo em que se encontram, as cooperativas agropecuárias precisam dar respostas econômicas, ao tempo em que são organizações que têm a capacidade de intervir na realidade social da população; ou seja, as cooperativas agropecuárias são atos locais que cumprem funções na promoção de melhores condições de vida para seus associados e são potenciais protagonistas do desenvolvimento rural. A conclusão aponta que considerar os serviços dos departamentos de assistência técnica e de extensão rural como uma ATER Cooperativa possibilitaria uma maior integração entre os setores administrativos, comerciais e financeiros da cooperativa, bem como o desenvolvimento coletivo dos cooperados.
Crime ambiental praticado pelo poder público municipal: uma análise sobre a aplicabilidade da Lei de Improbidade Administrativa
Authors: Lima Greice Kelli Lopes Santos de , Tagliaferro Evandro Roberto , Frias Danila Fernanda Rodrigues , Campato Jr João Adalberto
Published: October 2023

O presente trabalho aborda a relação entre o Estado e o meio ambiente, objetivando avaliar os inquéritos abertos pelo Ministério Público do Estado de São Paulo (MPSP) e pelo Ministério Público Federal (MPF) de Jales, da 24ª e 37ª Subseção Judiciária Federal, a coerção e a sanção dos crimes ambientais de atos e/ou omissões dos agentes públicos municipais (prefeitos) perante a Lei de Improbidade Administrativa, decorrente do dano ambiental. O estudo foi realizado por meio de coleta de dados com o MPSP e o MPF de 48 municípios da região noroeste paulista, em procedimentos abertos no período de janeiro de 2008 a agosto de 2021, cujos réus fossem prefeitos e municípios. Após a coleta de dados, houve a tabulação e a correlação com a bibliografia, a legislação e a jurisprudência encontrada. Identificou-se que foram abertos 120 procedimentos, e a maioria desses inquéritos evoluiu para ações civis públicas pelo MPSP, sendo que grande parte deles eram inquéritos civis, enquanto os restantes eram inquéritos policiais. Além disso, o MPF de Jales abriu um total de 606 procedimentos, e a maioria deles evoluiu para ações civis públicas. Conclui-se que o MPSP das comarcas e o MPF de Jales vêm cumprindo o dever constitucional na proteção ambiental; entretanto, identificou-se que os prefeitos acabam não sofrendo sanções da Lei de Improbidade Administrativa por crimes ambientais. Observou-se que o principal objetivo do Ministério Público Estadual e do Federal é a reparação do dano e a cessação da atividade que o gera, e não a coerção do agente que pratica ou omite ações geradoras do dano ambiental.
Influência do clima urbano da cidade de Campo Grande, MS, na quantidade de casos registrados de dengue: um estudo de caso via modelo de regressão Poisson
Authors: Saraiva Erlandson Ferreira , Sauer Leandro , Flesh Mariana Villela
Published: October 2023

No Brasil, o primeiro caso de dengue foi registrado na década de 1980 e, desde então, os casos vêm ocorrendo de forma continuada, sendo atualmente um dos principais problemas de saúde do país. Como a proliferação do mosquito transmissor da doença depende de variáveis ambientais, tais como temperatura e chuvas, para completar seu ciclo de vida, é de interesse entender as relações existentes entre o clima e os casos de dengue. Com o objetivo de contribuir com o sistema de vigilância da dengue na cidade de Campo Grande, MS, este artigo propõe um modelo estatístico para identificar as variáveis climáticas que podem estar relacionadas com o número de casos de dengue. Identificadas as variáveis, o modelo ajustado permite fazer projeções e simular diferentes cenários. Dessa forma, pode auxiliar na tomada de decisões com relação à implementação de medidas de combate e/ou controle do mosquito transmissor. Além disso, desenvolvemos um estudo para verificar a existência de períodos de defasagem, i.e., se o número de casos de dengue registrado em um mês depende dos valores registrados para as variáveis ambientais no mês anterior ou do mês atual.
Air-permeable heat flow and temperature sensor
Authors: Bobkov Yuryi
Published: October 2023

The paper considers ways of designing heat flow sensors and developed the design of an air-permeable heat flow and temperature sensor. The operating principle of the sensor is based on measuring the temperature difference using two temperature transducers placed at a fixed distance. The advantage of the proposed sensor is the possibility of simultaneous measurement of heat flow and temperature without the use of additional transducers, as well as air and moisture permeability, which is critical when measuring the parameters of biological objects. The sensor is designed taking into account the possibility of combining individual sensors into a single matrix of the required configuration.

A thermal model has been developed for the sensor, which can be used for engineering calculations of its parameters, research of metrological characteristics and analysis of ways to improve the accuracy of measurements.

The research fully confirmed the correctness of the developed thermal model and the operability of the proposed sensor design.
INTERPRETATION ULUMUL QUR’AN COURSE AS THE FOUNDATION FOR MODERATE UNDERSTANDING OF FEBI IAIN PONTIANAK STUDENTS, WEST KALIMANTAN PROVINCE
Authors: Abdurrahman Abdurrahman , Irfan Muhammad , Bilhaq M. Agus Muhtadi
Published: October 2023

This article reveals the existence of the “Ulumul Qur’an” course taught as the foundation for a Moderate Understanding among students of the Faculty of Islamic Economics and Business (FEBI) at the State Islamic Institute (IAIN) in Pontianak, which is located in West Kalimantan Province, a province known for its diversity in terms of ethnicity, traditions, and religions, but coexist peacefully and harmoniously in their daily lives. This article is a form of library research that uncovers the moderate values from the Ulumul Qur’an materials as well as its teaching methods. Therefore, the method used is qualitative research with a descriptive approach, where the data were collected through literature studies or documents discussing this theme, both from books and from recent online articles discussing the Ulumul Qur’an and religious moderation, and directly observed the environment at FEBI IAIN Pontianak, so that the collected data can be verified and revealed with reliable results. The instilling of moderate values towards the students of FEBI IAIN Pontianak is largely derived from the Ulumul Qur’an materials taught by a lecturer, although in delivering the material, the main focus of achievement is the understanding of the materials that have been agreed in the semester Learning Plan (RPS). The materials include Jam‘ al-Qur’ān (collection of the Qur’an), Qirā’ah al-Qur’ān (reading of the Qur’an), Asbāb al-Nuzūl (causes of the revelation of the Qur’an), and materials about the interpreters of the Qur’an, their conditions, and interpretation methods.
Mine Productivity Upper Bounds and Truck Dispatch Rules
Authors: Lisboa Adriano Chaves , Castro Felipe Luz Barbosa , Venâncio Pedro Vinícius Almeida Borges de
Published: October 2023

This paper proposes an upper bound for mine productivity and also a simple truck dispatch rule that demonstrates how tight the upper bound can be using simulation. It also proposes a greedy search to approximate the productivity upper bound, which is faster and often exact. Uncertainty is added to the simulation in order to verify how the productivity responds to it. Typically, the productivity upper bound is less tight close to its saturation point as a function of the number of trucks, where adding more trucks only increases queues. Furthermore, more uncertainty in the model typically leads to a less tight upper bound. The results are conducted using real data from an open pit mine in Brazil.
Validation of the Cognitive Reserve Index Questionnaire (CRIq) in Arabic
Authors: Darwish Hala , Farran Natali
Published: October 2023

Cognitive reserve is the adaptability of cognitive processes in the face of brain aging and pathology. This study aimed to validate the Arabic version of the Cognitive Reserve Index Questionnaire (CRIq) in a healthy Lebanese sample. CRIq assesses cognitive reserve through three domains: education, working activity, and leisure time. Statistical measures, including descriptive and regression analysis along with structural equation modeling, were utilized to investigate the convergent and discriminant validity of CRIq, incorporating fluid intelligence (Gf) and measures of cognitive function, long-term memory encoding and retrieval (Glr), and processing speed (Gs).
Results from 174 participants revealed that the activities assessed by CRIq-Arabic were comparable to the original CRIq study, with slight cultural differences. The internal consistency of CRIq-Arabic was good (Cronbach's α = 0.88), indicating reliability. Convergent validity was confirmed, with moderate to high loadings on the cognitive reserve latent construct. Discriminant validity was supported as correlations between cognitive reserve variables and non-target constructs (Gf, Glr, Gs) were less than 1.
The findings provide an initial psychometric validation of the CRIq-Arabic. Further research in clinical samples is needed to enhance its utility in neuropsychological practice.

Authors: Yuan Ligang , Jin Jiazhi , Chen Haiyan , Zhang Linghui , Zeng Yang
Published: October 2023

Accurate prediction of the degree of airport delays under the influence of convective weather is crucial for collaborative traffic management implementation and improving the efficiency of airport operations. However, existing studies usually only consider numerical-type quantitative features of weather-affected traffic in their models, and lack the introduction of spatial information to comprehensively portray the traffic operation scenarios under the influence of weather. In order to overcome this problem, this paper firstly designs a new image representation of weather-affected air traffic, and constructs a multi-channel traffic and weather scene image (MTWSI) by populating the airspace two-dimensional grid with traffic and meteorological information to represent the overall traffic operation situation in the terminal area under the influence of convective weather; then, a deep convolutional neural network-based airport delay prediction model ( ADLCNN), which takes MTWSI images as input and uses a specific CNN model to extract the deep features that affect traffic operation in it to input into the subsequent classification algorithm to predict the flight delay level; finally, a series of comparative experiments are carried out on the operational data of Guangzhou Baiyun Airport, and the experimental validation shows that, compared with the traditional machine learning methods, the proposed CNN-based airport delay prediction The experimental validation shows that the proposed CNN-based airport delay prediction model has satisfactory prediction performance compared with the traditional machine learning methods, which also proves that the proposed MTWSI method can more comprehensively respond to the real traffic conditions.

Introduction: Intrauterine fetal death (IFD) is death of fetus after the 20th week of gestation. Despite regular monitoring, the incidence of IFD remains high. This study aims to assess the incidence and risk factors for IFD in term pregnancies for better prevention and reduction of neonatal morbidity and mortality.
Materials and Methods: A retrospective cohort study was conducted with term pregnant women diagnosed with IFD. The analysis included the number of deliveries, live births, and stillbirths. Statistical analysis involves descriptive and analytical statistical methods.
Results: Average age was 30 years. Most patients had intermediate and high education, and one-third of patients had regular pregnancy monitoring. 53.33% were primiparous, and pregnancies occurred spontaneously. IFD mainly occurred in the 39th week of gestation. The average birth weight was approximately 3000g. 38.3% had one to two associated diseases, 5% more than three, and 56.7% were healthy. Recurrence of IFD was reported by 10% of patients, while 8.33% had a history of spontaneous abortion. Over 80% of placental histopathological findings indicated some pathology (infarction, infections, abruptio placenta).
Conclusion: The most significant risk factors were pregnancy-induced hypertensive disorders, obesity, and diabetes, followed by hypothyroidism, maternal tachycardia, and anemia.
A Computational Study of Hydrogen Dispersion and Explosion after Large-Scale Leakage of Liquid Hydrogen
Authors: Choi Seong Yong , Oh Chang Bo , Do Kyu Hyung , Choi Byung-Il
Published: October 2023

This study employs the FLACS code to analyze hydrogen leakage, vapor dispersion, and subsequent explosions. Utilizing pseudo-source models, a liquid pool model, and a hybrid model combining both, we investigate dispersion processes for varying leak mass flow rates (0.225 kg/s and 0.73 kg/s) in a large open space. We also evaluate explosion hazards based on overpressure and impulse effects on humans. The computational results, compared with experimental data, demonstrated reasonable hydrogen vapor cloud concentration predictions, especially aligned with the wind direction. For higher mass flow rate of 0.73 kg/s, the pseudo-source model and hybrid model proved appropriate, while the liquid pool model was more suitable for lower mass flow rate of 0.225 kg/s. Regarding explosion analyses using overpressure-impulse diagram, higher mass flow rates leaded to potentially fatal overpressure and impulse effects on humans. However, lower mass flow rates may cause severe eardrum damage at the maximum overpressure point.

Enhancing Intersection Efficiency through Smart Green Time Allocation at a Signalized Intersection Equipped with Two LiDAR Sensors
Authors: Ansariyar Alireza
Published: October 2023

Traffic signal control plays a key role in managing urban traffic flow, enhancing safety, and minimizing congestion and conflicts. Effective green time allocation is a critical element of this control process. This research explores the utilization of LiDAR sensor technology in the optimization of green time allocation for one phase of a traffic signal at a signalized intersection. LiDAR sensors provide precise and real-time data on vehicle presence and traffic patterns, enabling a data-driven approach to traffic signal control. The study begins with an analysis of the limitations of traditional traffic signal control strategies, which often rely on fixed-time plans or rudimentary vehicle detection systems. These approaches can lead to suboptimal green time allocation, resulting in inefficient traffic management and increased vehicle delays.The integration of LiDAR sensors provides detailed information on vehicle queues, arrival rates, and vehicle types. The research presents a practical framework for green time allocation optimization, considering factors such as intersection geometry, traffic volumes, and signal coordination. An intelligent control algorithm was developed that uses LiDAR data to determine the optimal green time for a specific phase, thereby reducing unnecessary waiting times and enhancing intersection efficiency. The effectiveness of the proposed LiDAR-based green time allocation strategy is demonstrated through extensive field tests. The results indicate significant improvements in intersection throughput, reduced delays, and enhanced traffic safety. In conclusion, this research highlights the transformative potential of LiDAR sensor technology in traffic signal control, specifically in the context of optimizing green time allocation. The findings support the notion that adaptive and data-driven strategies, when integrated with LiDAR sensors, can contribute to more efficient, sustainable, and safe urban traffic management. This research aims to provide valuable insights for transportation engineers, policymakers, and researchers seeking innovative solutions for modern urban traffic control.

Authors: Nie Shihao , Liu Keyi , Liu Ben , Li Piwu , Su Jing
Published: October 2023

To study the fermentation process of biocatalyzing decanoic acid to synthesize trans-2-decenoic acid, this study was based on the engineering E.coli constructed in the laboratory in the early stage and studied the effect of seed liquid culture time, culture temperature, inoculum amount, induction temperature, dissolution effects of substrate solvent, metal ions, and substrate loading on the yield of trans-2-decenoic acid. Based on single-factor experimental optimization, the Box–Behnken design was used to conduct response surface testing using the substrate feeding concentration, inducer concentration, and MnCl2 concentration as response variables and trans-2-decenoic acid production as the response value. The optimal fermentation process was determined through experiments: seed culture time 20 h, culture temperature 37°C, inoculation amount 1%, induction temperature 30°C, substrate flow amount 0.15 g/L, inducer concentration 5.60 g/L, MnCl2 concentration was 0.10 mM. Under these conditions, the average production of trans-2-decenoic acid was 1.982 ± 0.110 g/L. Compared with the basic LB medium, the production of trans-2-decenoic acid increased by 1.042 g/L; compared with the previous period, the yield of trans-2-decenoic acid studied increased by 1.501 ± 0.110 g/L, which provides a reliable basis for further research on the fermentation process of biocatalytic decanoic acid synthesis of trans-2-decenoic acid.
An Effective Method for Detecting Unknown Types of Attacks Based on Log-Cosh Variational Autoencoder
Authors: Yu Li , Xu Liuquan , Jiang Xuefeng
Published: October 2023

The rising number of unknown-type attacks on the Internet emphasizes the significance of developing efficient intrusion detection systems, even if machine learning-based techniques can detect unknown types of attacks. The necessity for innovative techniques is highlighted by the possibility that traditional machine learning techniques will not be sufficient for identifying these unknown types of attacks. In this research, we address this difficulty by proposing a deep learning-based solution: the log-cosh variational autoencoder (LVAE). When it comes to understanding intricate data distributions and creating freshly reconstructed data, LVAE inherits the strong modeling skills of the variational autoencoder (VAE). To better imitate discrete features of actual attacks and generate unknown types of attacks, this study develops an effective reconstruction loss term employing the logarithmic hyperbolic cosine (log-cosh) function in the log-cosh variational autoencoder (LVAE). When compared to conventional VAEs, LVAE exhibits promising potential for effectively generating data that closely resembles an unknown attack, a crucial capability for increasing the unknown attack detection rate. To categorize the generated unknown-type data, eight feature extraction and classification techniques were used. Using the most recent CICIDS2017 dataset, numerous experiments were carried out, training under varying amounts of real and unknown-type attacks. Our optimal experimental results outperformed several state-of-the-art techniques with accuracy and average F1 scores of 99.89% and 99.83%, respectively. Outstanding results were also shown by the suggested LVAE strategy for producing unknown attack data. In general, our work sets a strong basis for the accurate and efficient identification of unknown types of attacks and contributes to the development of intrusion detection techniques.

Ferroptosis is a recent form of non-apoptotic cell death, which occurs due to imbalance of iron homeostasis (iron overload). Oxidative stress due to the impairment of the antioxidant system is a major pathophysiology during ferroptosis, which eventually results in lipid peroxidation. The cellular and physiological biomarker of ferroptotic cell death includes major alteration in the glutathione peroxidase 4 (GPX4) antioxidant system and lipid peroxidation induced loss of plasma membrane integrity. This review elaborates the mechanism of oxidative stress which triggers ferroptosis.

A new power receiving unit (PRU) is proposed in this paper for the resonant wireless power transfer (WPT), which is characterized by the capability of attracting high power from the power transmitting unit (PTU). The resonant WPT is designed for delivering the electrical power to the PRU attached on an electrical vehicle (EV) chassis 50cm away from a PTU installed on the ground. The proposed PRU uses only the passive elements such as inductors, diodes and the capacitors, which needs no initial power from the EV. It is then applicable for charging a battery to several hundred volts for even a first-time charging battery. At a switching frequency of the resonant WPT in the experiment being 4MHz, the proposed PRU behaves itself as a negative impedance converter (NIC) in the subharmonics of 4MHz. The NIC effect plus the subharmonic oscillation causes an instability current charging the battery connected to the PRU. In this paper, we simulated the PRU and performed the experiment. The experiment demonstrates a battery charging of 150W from 50cm away using three D-mode GaN HEMT transistors via the instability current ramp. The power transfer efficiency (PTE) improved as the power delivered to load (PDL) goes higher. The best power transfer efficiency (PTE) is 65% in the present findings. The simulation analysis shows that the circuit allows itself be used to much higher power transfer when it is implemented with more GaN HEMT transistors connected in parallel. The theoretical derivation of the PRU circuit is also used to support both the experimental and simulation results.
Disturbance Observer-Based Model Predictive Control for an Unmanned Underwater Vehicle (UUV)

Published: October 2023

This work focuses on addressing the dynamic positioning and trajectory tracking problem for a 4 degree-of-freedom (DOF) unmanned underwater vehicle (UUV) in the presence of nonlinear dynamics, parametric uncertainties, system constraints, and time-varying external disturbances. To tackle this problem, a disturbance observer-based control (DOBC) scheme is proposed. The scheme is structured around the model predictive control (MPC) method integrated with an extended active observer (EAOB). Compared to the conventional disturbance observer, the EAOB has the unique ability to handle both external disturbances and system/measurement noises simultaneously. The EAOB leverages a combination of sensor measurements and a system dynamic model to estimate disturbances in real-time, which allows continuous estimation and compensation of time-varying disturbances back to the controller. The proposed disturbance observer-based MPC (DOBMPC) is implemented by feeding the estimated disturbances back into the MPC’s prediction model, which forms a robust adaptive controller with a parameter-varying model. The proposed control strategy is validated through simulations in a Gazebo and Robot Operating System (ROS) environment. The results show that it can effectively reject unpredictable disturbances and improve the UUV’s control performance.

Published: October 2023

Energy supply interruptions or blackouts caused by faults in power distribution feeders entail several damages to power utilities and consumer units: financial losses, damage to power distribution reliability, power quality deterioration, etc. Most studies in the specialized literature concerning faults in power distribution systems present methodologies for detecting, classifying, and locating faults after their occurrence. In contrast, this study aims to prevent faults by estimating the city regions whose power grid is most vulnerable to them. This work incorporates the geographic space study to prevent faults in the distribution power grid through a spatial data analysis using local variables that increase the fault risk in feeders in some city regions. Geographically weighted spatial analysis is applied to data aggregated by regions to produce thematic maps with the city regions whose feeders are more vulnerable to failures. Spatial data analysis is developed in QGIS and R programming environments. It is applied in real data of electrical discharges in a medium-sized city with approximately 200,000 inhabitants. In this study, we highlight a moderate positive correlation between electrical discharge density and the percentage of faults in transformers by regions in the central and western areas of the city under study.

Introduction. The drive electric motor is one of the key components in the traction chain of an electric vehicle. Traditional radial flux motors used in electric vehicles, which use permanent magnets or induction motors in an electric field, are experiencing significant development aimed at optimizing their weight and cost. However, it can only go so far, so switching to a completely different type of machine, such as an axial flow, might be a good alternative. The novelty to this item is an axial flux permanent magnet motorization with non-slotted TORUS-NS rotor (single interior stator with two external rotors North-South) type housed in the wheel of the vehicle; this allows power to pass directly from the motor to the wheel, increasing the efficiency of the motor. System complexity is also less, as the transmission, differentials and driveshaft are eliminated. Purpose is to equip the electric car and choose the motor adapted to the application and the available space. The smaller size and weight allows for a lighter vehicle and more batteries, thus increasing range. The focus on customization is because vehicle performance is so dependent on the quality of the vehicle architecture , battery pack and axial flux motor design. The results obtained are in good agreement of accuracy, in particular the flux density at the air gap. The investigation is carried out by the finite element method. Machine model was run on Maxwell 16.0 business code.
