Published: October 2024

Addressing the challenges related to urban water bodies is essential for advancing urban planning and development. Therefore, obtaining precise and timely information regarding urban water bodies is of paramount importance. To address issues such as incomplete extraction boundaries, mistaken feature identification, and omission of small water bodies, this study utilized very high-resolution (VHR) satellite images of the Chengdu urban area and its surroundings to create the Chengdu Urban Water Bodies Semantic Segmentation Dataset (CDUWD). Based on the shape characteristics of water bodies, these images were processed through annotation, cropping, and other operations. We introduced Ad-SegFormer, an enhanced model based on SegFormer, which integrates a densely connected atrous spatial pyramid pooling module (DenseASPP) and progressive feature pyramid network (AFPN) to better handle the multi-scale characteristics of urban water bodies. The experimental results demonstrate the effectiveness of combining the CDUWD dataset with the Ad-SegFormer model for large-scale urban water body extraction, achieving accuracy rates exceeding 96%. This study demonstrates the effectiveness of Ad-SegFormer in improving water body extraction and provides a valuable reference for extracting large-scale urban water body information using VHR images.

Published: October 2024

Dryland lakes are indispensable to regional water resource systems. Ebinur Lake, the largest saline lake in Xinjiang Uygur Autonomous Region, is vital for regional biodiversity and environmental stability but has been facing the predicament of gradual shrinkage in recent decades. In this study, we proposed a new dual-index method for Landsat (-5, -7, -8, and -9) data to extract water with the combinations of the normalized difference water index (NDWI) and the modified NDWI for turbid waters (NDWIturbid). The dual-index method showed a high overall accuracy of 96.36% for Ebinur Lake. Landsat series images from 1992 to 2023 were employed to acquire the water areas of Ebinur Lake. The results showed that, over the past three decades, the area of Ebinur Lake exhibited a fluctuating decreasing trend, with an average lake area of 568.74 ± 152.43 km². The northwest intermittent water areas showed significant changes, and there was a close connection between the northwest and core water areas. Seasonally, the lake area decreased from spring to autumn. River inflow, driven by rainfall and human activities, was the primary factor affecting the inter/inner annual changes in Ebinur Lake. Furthermore, due to the valley effects, wind was found to be a critical factor in the diurnal changes in the water areas. This study should deepen the understanding of the variations of Ebinur Lake and benefit local water resource management.

Published: October 2024

The use of session rating of perceived exertion (sRPE) as a measure of workload is a popular athlete load monitoring tool. However, the nature of sRPE means the contribution of salient, sport-specific factors to athlete load in field sports is challenging to isolate and quantify. In rugby sevens, drivers of load include high-speed running and physical contact. In soccer and men’s rugby, union acceleration/deceleration also influences load. These metrics are evaluated using data from global navigation satellite system (GNSS) sensors worn by athletes. Research suggests that sensor data methods for identifying load in men’s rugby do not accurately quantify female athlete loads. This investigation examined how mass, contact, and accelerations and decelerations at different speeds contribute to load in women’s rugby sevens. The study evaluated 99 international matches, using data from 19 full-time athletes. GNSS measures, RPE, athlete mass, and contact count were evaluated using a linear mixed-model regression. The model demonstrated significant effects for low decelerations at low and high speeds, mass, distance, and contact count explaining 48.7% of the global variance of sRPE. The use of acceleration/deceleration and speed from GNSS sensors alongside mass, as well as contact count, presents a novel approach to quantifying load.

Authors: Pardo Solórzano Manuela Victoria , Costa Geison Modesti , Castellanos Leonardo
Published: October 2024

The cosmetics industry is constantly growing and occupies an important place in South American countries’ economies. Formulations increasingly incorporate ingredients from natural sources to promote sustainable and innovative productions, as well as to gain greater consumer acceptance. According to FAO, waste from post-harvest and food processing in developing countries exceeds 40%, generating significant environmental impacts and stimulating interest in adding value to these wastes, particularly in the fruit and vegetable sector in South American countries, thus contributing to the achievement of the UN Sustainable Development Goals (SDGs). By-products from harvesting and fruit processing of Passiflora species such as leaves, stems, peel, and seeds are a source of bioactive compounds; however, most of them are wasted. This study aims to compile reports on the chemical composition of cultivated Passiflora species, find evidence of the cosmetic activity of their extracts, and estimate their potential for inclusion in cosmetic formulations.

Published: October 2024

Background: Nephrolithiasis, or kidney stone disease, presents a significant global health burden, with global incidence rates and treatment practices varying widely. This study aims to discuss the epidemiology, risk factors, treatment modalities, and challenges for nephrolithiasis in the lower half of the World Bank rankings; that is, in low- and lower-middle-income countries. Methods: A comprehensive literature review was conducted using PubMed for each country on the list, focusing on studies published from January 2000 onwards and reporting data on prevalence, risk factors, treatment practices, and economic implications. Results: Nephrolithiasis represents a significant burden for healthcare systems, with noteworthy geographical variability in prevalence possibly dependent on socioeconomic status and gender. Risk factors include dietary habits, climate, pollution, and infectious diseases. Treatment practices in some regions still rely on open surgery due to limited access to advanced endourological techniques, while other regions demonstrate high proactivity in research. The burden is exacerbated by inadequate healthcare infrastructure and training. Conclusions: Addressing nephrolithiasis in challenging economic circumstances requires targeted interventions, including improved access to modern treatment methods, enhanced training for healthcare professionals, and better socioeconomic and environmental conditions. Future research should focus on region-specific strategies and the development of sustainable healthcare solutions.
Understanding Household Income Inequality in Rural Vietnam: A Regression-Based Decomposition Study
Authors: Tran Thi Thu Thuy , Tsuji Kazunari , Fujimura Miho
Published: October 2024

Along with the rapid economic development that rural Vietnam has experienced since the implementation of the Doi Moi policy, increasing attention is being paid to the widening income inequality among rural households. Although several studies have been conducted to understand the drivers of rural inequality, there is a lack of analysis that considers different household characteristics simultaneously and quantifies their contributions to inequality. Our study aims to fill this gap by applying the Fields’ regression-based decomposition method to household data collected from VARHS 2012 and VARHS 2016. The analysis results show that human capital, indicated by the quantity and quality of working members, and physical capital, indicated by household mobility and access to information, are the main contributors that explain this inequality. Additionally, the decreasing variation in specific characteristics, such as education level, is found to reduce their contribution to inequality over time, consequently preventing these factors from exacerbating overall inequality.

Authors: Yang Feng , Chen Tingwei , Zhang Zongbin , Yao Kan
Published: October 2024

Promoting firms’ green evolution and achieving sustainable, high-quality development have become crucial for firms’ sustainability. This study uses data from publicly listed automotive manufacturing firms from 2009 to 2022 to examine the impact of target firms’ environmental, social, and governance (ESG) performance on total-factor productivity (TFP) at upstream and downstream firms from a supply-chain perspective. By employing a two-way, fixed-effects model, mediation analysis, and a moderation model, the study provides comprehensive insights. The findings reveal the following: (1) The ESG performance of target firms in automotive manufacturing significantly improves the TFP of downstream customers, and this conclusion is robust even when using instrumental variable methods, additional control variables, and rigorous robustness tests. (2) Mechanism analysis indicates that the ESG performance of target firms alleviates the financing constraints of their customers, thereby positively impacting the customers’ TFP. Additionally, the study finds that the monopolistic power of the target firm negatively moderates the relationship between its ESG performance and the TFP of its customers. These empirical findings enhance the understanding of supply-chain spillover effects and provide a new theoretical foundation for improving firms’ ESG performance.

Published: October 2024

Achieving significant breakthroughs in both the fundamental theories and technological applications of artificial intelligence is essential for fostering its long-term development. Under the guidance of Professor Qian Xuesen’s theory of technological science, exploring the internal mechanisms of knowledge evolution in artificial intelligence holds profound theoretical and practical significance for promoting sustainable technological advancement. This study draws on literature from the Web of Science (WOS) database and employs methods such as knowledge mapping, natural language processing, clustering analysis, and citation analysis to outline the knowledge structure of the field, clarify the trajectory of sustainable development, and trace the technological genealogy of VR/AR technologies.This study divides the knowledge structure within the field of technological science into “basic theoretical knowledge—applied basic knowledge—applied knowledge”, enriching Qian’s theory of technological science from within and providing strong intellectual support and technological pathways for sustainable technological development in practice. Artificial intelligence encompasses 10 distinct knowledge domains, among which machine learning and deep learning constitute the basic theoretical knowledge, data intelligence, computer vision, and swarm intelligence are the applied basic knowledge, and image processing and human-computer intelligence are the applied knowledge. The development of VR/AR technology has formed two main sustainable development paths: “machine learning—data intelligence—intelligent systems—human computer intelligence”, and “deep learning—computer vision—image processing”.
Evaluation of the Feasibility and Utilizability of Pretreated Sewage Sludge in Cement Kiln Co-Processing
Authors: Cheng Wei , Lin Xiaohu , Liu Wei , Cao Haihua , Xu Jingcheng
Published: October 2024

The treatment and resource utilization of sludge from municipal sewage treatment plants is an important environmental issue. Cement kiln co-processing offers a promising solution, but challenges remain, particularly regarding sludge properties and feasibility in kiln systems. This study analyzes the characteristics of three pretreated sludges: mechanically dewatered sludge, deeply dewatered sludge, and lime-dried sludge. Using techniques such as thermogravimetric analysis (TGA) and X-ray diffraction (XRD), this study investigates their calorific values and raw material utilizability in co-processing. As the sludge moisture content decreases from interstitial to bound water, energy consumption per ton of evaporated water rises, particularly below 30%. At 10 °C/min heating, energy consumption for mechanically dewatered sludge at 80%, 30%, and 10% moisture was 3573, 8220, and 34,751 kJ/kg, respectively; for deeply dewatered sludge at 60%, 30%, and 10%, the values were 4398, 7550, and 11,504 kJ/kg. Keeping moisture content above 30% before kiln entry reduces energy use and enhances calorific value. Sludge utilizability as a raw material depends on its pretreatment. The ash composition of deeply and mechanically dewatered sludge resembles iron-rich raw materials, while lime-dried sludge aligns more with limestone. The utilizable ash content was 23.3%, 8.1%, and 46.3%, respectively, with lime-dried sludge showing the highest potential. This study provides insights into sludge properties and their co-processing potential in cement kilns, offering scientific and technical support for practical applications.
Stand Characteristics, Leaf Traits and Growth of Threatened Conifer Pilgerodendron uviferum (Cupressaceae) in Southern Patagonia, Argentina
Authors: Peri Pablo L. , Bahamonde Hector , Toledo Santiago , Martínez Pastur Guillermo
Published: October 2024

Pilgerodendron uviferum is an endemic Cupressaceae of Patagonia (Argentina) that is restricted to a small group of individual trees, growing in isolated populations (relicts) along its distribution. The main objective was to evaluate the habitat, forest structure, leaf traits, leaf nutrient reabsorption and growth of four relicts (area between 0.3 and 0.86 ha) in the Santa Cruz province (Argentina) to improve the available information for forest conservation purposes. Principal components analysis was conducted to determine the separation between relict populations based on their ecological characteristics (individual and habitat levels). We found contrasting environmental and forest structure conditions among the four studied relicts. For example, two relicts associated with Nothofagus antarctica showed higher values of P. uviferum tree density, DBH and dominant height at the stand level. Alongside that, these relicts presented a higher sapling density (1950–3167 ind ha−1) and understory plant diversity compared to pure P. uviferum relicts growing near the ecotone with the steppe grassland. Specific leaf area, carbon and nutrient concentrations in P. univerum leaves varied depending on the relict conditions and tree age of the individuals. The mean nutrient resorption efficiency varied according to relicts and particular nutrients, ranging from 18.1% to 49.5% for Ca and P, respectively. The diameter growth of the dominant P. univerum trees ranged from 0.33 to 0.46 mm yr−1, indicating that the species follows a stress-tolerant strategy. The information of this work may assist in the conservation of marginal P. uviferum forest communities spatially disconnected with continuous forests, growing in relicts.
Comparative Analysis of Gini Coefficient, GDP, Energy Consumption, and Transportation Modes on CO2 Using NARDL (Nonlinear Distributed Lag Autoregressive Model) for the USA
Authors: Artekin Ayşe Özge , Kalayci Salih
Published: October 2024

The significance of the transportation sector, notably in terms of the carbon emission factor, is an undeniable fact. Along with this fact, individuals’ transportation preferences depend on their income levels. In this context, when the issue is considered, the income level in the USA pushes people toward cheap air travel. The main reason for this is that it is cheap, accessible, and transports one to their destinations quickly. Thus, from the perspective of road transportation, bus transportation is popular among the public. The reason why both air and road transportation modes are empirically evaluated together through income distribution is due to the preference of the US people. In this context, the effectiveness of active transportation on both air and highways in the USA from 1975 to 2023 is investigated by taking into consideration the income distribution. Empirical findings obtained through the FMOLS, DOLS, CCR, and NARDL models demonstrate that all independent variables, including GDP, energy use, air transportation, and the Gini coefficient, affect carbon dioxide emissions. In addition, wavelet analysis is performed to comprehend the form of and fluctuations in the series, which are vital to monitoring the periodical changes.
Asymmetry in Galaxy Spin Directions: A Fully Reproducible Experiment Using HSC Data
Authors: Shamir Lior
Published: October 2024

The asymmetry in the large-scale distribution of the directions in which spiral galaxies rotate has been observed by multiple telescopes, all showing a consistent asymmetry in the distribution of galaxy spin directions as observed from Earth. Here, galaxies with a redshift from HSC DR3 are annotated by their direction of rotation, and their distribution is analyzed. The results show that galaxies that rotate in the opposite direction relative to the Milky Way as observed from Earth are significantly more prevalent compared to galaxies that rotate in the same direction relative to the Milky Way. The asymmetry also forms a dipole axis that becomes stronger when the redshift gets higher. These results are aligned with observations from virtually all premier digital sky surveys, as well as space telescopes such as the HST and the JWST. This shows that the distribution of galaxy spin directions as observed from Earth is not symmetrical, and has a possible link to the rotational velocity of the Milky Way. This experiment provides data, code, and a full protocol that allows the results to be easily reproduced in a transparent manner. This practice is used to overcome the “reproducibility crisis” in science.

Published: October 2024

Chromobacterium violaceum is a Gram-negative, facultative anaerobe proteobacterium. Its natural habitat is water and soil in tropical and subtropical regions. Human infections are characterized by rapid dissemination that can lead to high fatality rates. Here, we describe the first case of a C. violaceum infection reported from Germany. A German national with permanent residence in French Guyana contracted a C. violaceum infection presumably while bathing in a barrier lake in Brazil. The patient presented with a high fever and a crusty, erythematous skin lesion at an emergency department in Hamburg, Germany. Ultrasound and a CT scan of the abdomen revealed multiple liver abscesses. C. violaceum was detected in blood and from aspirates of the liver abscesses, using traditional culture methods and modern molecular assays. Prolonged treatment with meropenem and ciprofloxacin led to full recovery. Rapid pathogen detection and treatment initiation are of high importance in C. violaceum infections as mortality rates are overall declining but have still tended to reach up to 25% in recent years in systemic infections. Due to its broad natural drug resistance, antibiotic treatment is challenging. Increased travel activities may lead to more frequent presentation of patients with environmental pathogens of the tropics such as C. violaceum.

Human bocavirus (HBoV) has been identified as a viral agent with a global presence, especially in young patients with gastrointestinal infections. In this study, we aimed to evaluate the epidemiological patterns of the HBoVs associated with acute gastroenteritis (AGE) in Taiwan. A total of 2994 AGE fecal samples from several diarrhea outbreaks from 2018 to 2022 were analyzed. From the samples, 73 positive samples were detected in three different bocaviruses: 30 (41.1%) were from HBoV1; 37 (50.7%) were from HBoV2; and 6 (8.2%) were from HBoV3, revealing the respective prevalences in AGE of 1%, 1.2%, and 0.2%. HBoV1 and HBoV2 were the two major epidemic agents of HBoVs in Taiwan during this study period and have seasonal distinct patterns with an epidemic peak from October to the following March. Phylogeny reconstruction and evaluation were implemented in Mega X; the results revealed that most HBoV1 strains in Taiwan appeared to be closely related to those strains from other Asian countries. The HBoV2 exhibited substantial genetic diversity and the HBoV3 genes showed discordance of groups.

Authors: Zhang Qianqian , Xu Shimin , Yang Li
Published: October 2024

To study the characteristics and sources of nitrogen in the Baiyangdian Lake, this research conducted water quality monitoring during three hydrological periods (normal period, flood period, and dry period), and 165 pieces of routine water quality monitoring data were collected from the three national control sections for Baiyangdian Lake and its inflow rivers. By integrating water chemical analysis with multivariate statistical techniques, the study comprehensively investigated the spatiotemporal variation patterns of nitrogen in Baiyangdian Lake and identified the sources of nitrogen pollution. The results showed that the concentration of total nitrogen (TN) was highest during the dry period, reaching an average of 0.924 mg/L, and 31.3% of the sites exceeded the national Grade III surface water quality standard, reflecting a potential risk of nitrogen pollution. Based on the ion ratio method and principal component analysis (PCA), the main sources of nitrogen pollution in Baiyangdian Lake were identified as manure and domestic sewage, with agricultural fertilizers also having a certain impact on water nitrogen pollution. In addition, the study also compared the nitrogen concentration in Baiyangdian Lake with several important lakes in China. The results showed that the concentrations of TN and ammonium nitrogen (NH4+-N) in Baiyangdian Lake are lower than those in lakes in areas with similar human activity intensity, indicating that the water quality of Baiyangdian is relatively good. This study can provide a scientific basis for water quality management and pollution prevention for Baiyangdian Lake.

Промышленные отрасли отличаются различной сложностью производственно-технического процесса, ввиду этого и оценка результативности зеленых инноваций промышленных предприятий должна учитывать данную дифференциацию. В данной работе проанализированы зарубежные методы оценки результативности зеленых инноваций в промышленности на макро-уровне. Были рассмотрены два подхода к оценке результативности эко-инноваций: метод патентной активности и метод интегральной оценки. В рамках метода интегральной оценки были изучены индексы эко-инноваций Европейской комиссии и Форума «Азия – Европа». Были выявлены особенности расчета, преимущества и недостатки данных методов. Основная гипотеза исследования заключается в том, что зарубежные методы оценки результативности зеленых инноваций на макро-уровне в недостаточной степени учитывают показатели, связанные с промышленными отраслями. В статье использованы такие методы, как теоретический анализ и синтез, сравнение, классифицирование. В результате подтверждено, что имеющиеся зарубежные методы имеют недостатки для оценки результативности зеленых инноваций с точки зрения промышленности. В заключении делается вывод о необходимости разработки такого метода оценки эко-инноваций, который будет учитывать дифференциацию промышленных отраслей и рассматривать качественные и количественные показатели.

Industrial sectors are distinguished by varying complexity of the production and technical process; therefore, assessing the performance of green innovations of industrial enterprises should take this differentiation into account. This paper analyzes foreign methods for assessing the performance of green innovations in industry at the macro level. Two approaches to assessing the performance of eco-innovations were considered: the patent analysis and the index method. Within the framework of the index method, the eco-innovation indices of the European Commission and the Asia-Europe Forum were studied. The calculation features, advantages and disadvantages of these methods were identified. The main hypothesis of the study is that foreign methods for assessing the performance of green innovations at the macro level do not sufficiently take into account indicators related to industrial sectors. The article uses methods such as theoretical analysis and synthesis, comparison, classification. As a result, it was confirmed that existing foreign methods have shortcomings for assessing the performance of green innovations from an industrial point of view. It is concluded that it is necessary to develop a method for assessing eco-innovations that will take into account the differentiation of industrial sectors and consider qualitative and quantitative indicators.

Несмотря на то, что статья 5.57 была введена в КоАП РФ в 2009 году, более реальным инструментом защиты права на образование она стала только с принятием нового федерального закона об образовании, которым вводились понятия образовательных отношений, субъектов образовательных отношений и их взаимные права и обязанности. При этом государство гарантировало условия реализации права на образование. В статье даётся обзор судебной практики и формулируются актуальные вопросы административной ответственности за нарушения образовательного законодательства как инструмента обеспечения конституционного права на образование. Автор отмечает педагогический потенциал административно-правового воздействия на участников образовательных отношений, допускающих нарушение права на образование. При этом отмечается задача государства через правоприменение демонстрировать приоритетность образования, своевременно реагировать на выявляемые нарушения, охраняя не только публичные, но и частные интересы, обеспечивать профилактику и устранение причин и условий, способствующих нарушениям, единообразное правоприменение и формирование правовой культуры всех участников отношений.

The subject of the presented work is the issues of administrative liability in connection with violation of the right to education. Despite the fact that Article 5.57 was introduced into the Code of Administrative Offenses of the Russian Federation in 2009, it became a more realistic instrument for protecting the right to education only with the adoption of the new federal law on education, which introduced the concepts of educational relations, subjects of educational relations and their mutual rights and obligations. At the same time, the state guaranteed the conditions for the realization of the right to education. The article provides an overview of judicial practice and formulates current issues of administrative liability for violations of educational legislation as a tool for ensuring the constitutional right to education. The author notes the pedagogical potential of administrative and legal influence on participants in educational relations that allow violation of the right to education. At the same time, the task of the state through law enforcement is to demonstrate the priority of education, to respond in a timely manner to detected violations, protecting not only public but also private interests, to ensure prevention and elimination of the causes and conditions that contribute to violations, uniform law enforcement and the formation of a legal culture of all participants in relations.

В статье говорится о современных информационных и цифровых технологиях, которые в настоящее время активно внедряются в отечественную правоохранительную деятельность, либо имеют перспективы такого внедрения. Проводится анализ конкретных государственных программ, нормативно-правовых актов и стандартов, связанных с использованием указанных технологий, рассматривается терминологическое содержание отдельных понятий в области цифровизации. При этом особое внимание уделяется Ведомственным программам цифровой трансформации МВД России на текущий период и перспективу. Делается вывод о возможности и перспективности использования в правоохранительной деятельности отдельных технологий, прежде всего, технологий искусственного интеллекта. Среди технологий искусственного интеллекта анализируются перспективы использования в процессе выявления, раскрытия и расследования преступлений нейросетей, прежде всего, специализированных. Кроме того, рассматриваются некоторые проблемы по внедрению современных информационных и цифровых технологий в правоохранительную деятельность. Отмечается, что к числу основных проблем в указанном направлении следует отнести надлежащую подготовку субъектов применения информационных и цифровых технологий, а также наличие достаточного и постоянного государственного финансирования. Делается вывод о том, что цифровизация (цифровая трансформация) правоохранительной деятельности является долгим, непростым, но перспективным и неизбежным процессом.

The reduction of inhomogeneous stress in diamonds is crucially important for extracting excellent performance of semiconducting diamonds. In this study, to investigate elastic deformation in nitrogen doped (111) diamond films caused by stress, we evaluated the stress in these films using confocal Raman microscopy. The stress was detectable when the misorientation angle (
