Published: December 2024

Microvolume ELISA platforms have become vital in diagnostics for their high-throughput capabilities and minimal sample requirements. High-quality substrates with advanced surface properties are essential for these applications. They enable both efficient biomolecule immobilization and antifouling properties, which are critical for assay sensitivity and specificity. This study presents PET-based microvolume ELISA spot arrays coated with amine- and DBCO-reactive copolymers MCP-2 and Copoly Azide. The platforms were designed for the sensitive and specific detection of specific antibodies such as COVID-19 biomarkers. Supporting robust attachment of the SARS-CoV-2 nucleoprotein (NP), these arrays outperform traditional approaches. It was demonstrated that covalent attachment methods proved more efficient than passive adsorption, together with the reduction of non-specific binding. Analytical performance was verified with classical ELISA and real-time Surface Plasmon Resonance (SPR) analysis. It enables sensitive detection of IgG and IgA antibodies, including IgG subclasses, in human serum. Clinically, the platform achieved 100.0% sensitivity and 92.9% specificity for anti-NP antibody detection in COVID-19-positive and negative samples. Additionally, DNA-directed immobilization extended the platform’s utility to multiplex serological measurements. These findings underscore the potential of PET-based microvolume ELISA arrays as scalable, high-throughput diagnostic tools suitable for detecting multiple biomarkers in a single assay and easily integrated into microfluidic devices.
Edge-Guided Feature Pyramid Networks: An Edge-Guided Model for Enhanced Small Target Detection
Authors: Liang Zimeng , Shen Hua
Published: December 2024

Infrared small target detection technology has been widely applied in the defense sector, including applications such as precision targeting, alert systems, and naval monitoring. However, due to the small size of their targets and the extended imaging distance, accurately detecting drone targets in complex infrared environments remains a considerable challenge. Detecting drone targets accurately in complex infrared environments poses a substantial challenge. This paper introduces a novel model that integrates edge characteristics with multi-scale feature fusion, named Edge-Guided Feature Pyramid Networks (EG-FPNs). This model aims to capture deep image features while simultaneously emphasizing edge characteristics. The goal is to resolve the problem of missing target information that occurs when Feature Pyramid Networks (FPNs) perform continuous down-sampling to obtain deeper semantic features. Firstly, an improved residual block structure is proposed, integrating multi-scale convolutional feature extraction and inter-channel attention mechanisms, with significant features being emphasized through channel recalibration. Then, a layered feature fusion module is introduced to strengthen the shallow details in images while fusing multi-scale image features, thereby strengthening the shallow edge features. Finally, an edge self-fusion module is proposed to enhance the model’s depiction of image features by extracting edge information and integrating it with multi-scale features. We conducted comparative experiments on multiple datasets using the proposed algorithm and existing advanced methods. The results show improvements in the IoU, nIoU, and F1 metrics, while also showcasing the lightweight nature of EG-FPNs, confirming that they are more suitable for drone detection in resource-constrained infrared scenarios.

Published: December 2024

Remote-sighted assistance (RSA) is a technology designed to provide assistance for visually impaired people (VIPs). In this scene, a remote-sighted agent communicates and sends commands to navigate and assist VIPs via real-time video sent back. However, the latency in real-time video and the deviation in the execution of instructions by VIPs are two important factors that affect the performance of agents to guide them. Therefore, how to enable agents to better guide VIPs under conditions of video transmission latency and deviation in instruction execution is an important issue. In this paper, we utilize Unreal Engine to create a virtual training platform for RSA, which simulates VIPs executing instructions in the real world and resembles the environment in RSA systems. We aim to help remote-sighted agents quickly master the set of vibration commands formed after encoding tactile vibrations and enable them to guide VIPs more effectively. Our experiment results show that, compared with untrained novices, when guiding people through the same path, agents trained on this platform reduce their average time by 32.09% and their average number of contacts with the environment by 57.57%. Our work provides agents with a simple and convenient simulation and training platform designed to enhance their performance by guiding VIPs with less travel time and fewer environmental contacts. Through this platform, agents can more effectively assist the visually impaired.

Published: December 2024

This paper presents a pH sensor with a Mach–Zehnder Interferometer (MZI) that operates in solutions of 4.0, 7.0, and 10.0. The sensor device consists of two tapered sections with dimensions of 1 mm/1 mm/1 mm for down-taper, waist-length, and up-taper, respectively, with a separation of 10 mm. The diameter of the waist is 40 μm. This work includes the experimental evaluation of an MZI fiber optic pH sensor at 1559 nm, where 1559 nm represents a specific wavelength chosen for its optimal sensitivity in evaluating the sensor pH detection performance. It is not the central wavelength of the optical fiber, but one of the minimal values selected to enhance the interaction between the evanescent field and the sample, ensuring the reliable detection of pH variations. These sensor dimensions and the functionalized solution of multi-walled carbon nanotubes (MWCNTs) increase the detection of pH in dyes used in the textile industry. Alizarin is a strong anionic red dye that is part of the anthraquinone dye group. The experimental results demonstrated effective detection of pH levels in water contamination involving dye. This development could resolve the problem with Alizarin. The simple fabrication, low cost, and stability of the optical response make this sensor relevant for pH measurements in water contamination.
A 2-Year Longitudinal Neuropsychological Study in Relapsing-Remitting Multiple Sclerosis: A Selective Decline in Social Cognition?
Authors: Ehrlé Nathalie , Papinsac Margot
Published: December 2024

Background/Objectives. Social cognition (SC), which implies the emotional and intellectual understanding of oneself and others, is an important facet of neuropsychological functioning concurrently to academic cognition (AC), which concerns non-social abilities (memory, language…). In relapsing-remitting multiple sclerosis (RRMS), it is not clear whether a cognitive decline occurs in both SC and AC nor whether a link exists between these two cognitive domains. The objective of the present longitudinal study was to conduct an extensive examination of both AC and SC in RRMS to document a 2-year evolution and to look for potential correlations between AC and SC. Methods. The neuropsychological results (AC and SC) of 48 RRMS patients obtained in clinical practice were retrospectively considered; 38 of the patients (30 females) were assessed again about 2 years later. Non-parametric tests were applied to test the intra-group cognitive evolution (Wilcoxon) and the link between AC and SC evolution (Spearman). Results. Whereas AC showed a stability or an improvement of performances during the retest, SC presented the reverse pattern, with a stability or a significant decline in facial emotion (recognition and discrimination) and humor perception. No significant statistical correlation was found between the significant modification of AC and SC during follow-up. Conclusions. The short-term deleterious evolution observed selectively for SC in the present study suggests that SC should be selected as a cognitive marker for RRMS follow-up, and that extensive examination may be preferred to investigate specific SC changes.
Analysing Quality Metrics and Automated Scoring of Code Reviews
Authors: Sortwell Owen , Cutting David , McConnellogue Christine
Published: December 2024

Code reviews are an important part of the software development process, and there is a wide variety of approaches used to perform them. While it is generally agreed that code reviews are beneficial and result in higher-quality software, there has been little work investigating best practices and approaches, exploring which factors impact code review quality. Our approach firstly analyses current best practices and procedures for undertaking code reviews, along with an examination of metrics often used to analyse a review’s quality and current offerings for automated code review assessment. A maximum of one thousand code review comments per project were mined from GitHub pull requests across seven open-source projects which have previously been analysed in similar studies. Several identified metrics are tested across these projects using Python’s Natural Language Toolkit, including stop word ratio, overall sentiment, and detection of code snippets through the GitHub markdown language. Comparisons are drawn with regards to each project’s culture and the language used in the code review process, with pros and cons for each. The results show that the stop word ratio remained consistent across all projects, with only one project exceeding an average of 30%, and that the percentage of positive comments across the projects was broadly similar also. The suitability of these metrics is also discussed with regards to the creation of a scoring framework and development of an automated code review analysis tool. We conclude that the software written is an effective method of comparing practices and cultures across projects and can provide benefits by promoting a positive review culture within an organisation. However, rudimentary sentiment analysis and detection of GitHub code snippets may not be sufficient to assess a code review’s overall usefulness, as many terms that are important to include in a programmer’s lexicon such as ‘error’ and ‘fail’ deem a code review to be negative. Code snippets that are included outside of the markdown language are also ignored from analysis. Recommendations for future work are suggested, including the development of a more robust sentiment analysis system that can include detection of emotion such as frustration, and the creation of a programming dictionary to exclude programming terms from sentiment analysis.

Published: December 2024

Household food waste accounts for a significant share of total food waste. In 2022, around 1.05 billion tons of food waste were generated—60% of which came from households. In the EU, households generate 54% of the total food waste. In Italy, according to a former diary study, avoidable household food waste accounts for 529.9 g per capita per week. Building on this data, this study assesses the monetary value of food waste at the household level in 6 provinces across the country, considering the prices of food items recorded by the Italian Observatory of market prices. Moreover, the environmental impacts of household food waste (greenhouse gas emissions, water consumed, and land used) were investigated based on existing data from well-grounded scientific literature. The results show that the monetary value of food waste ranges from EUR 357.43 to EUR 404.62 per household per year, corresponding to 5–7% of the average household expenditure for food. The environmental impacts per household per year account for 149 kgCO2eq, which contributes to climate change. In addition, household food waste is responsible for 303,498 L of water consumed and 1426 m2 of land used. The results of this study can be integrated into National Energy and Climate Plans (NECPs), to integrate food waste reduction into energy savings and greenhouse gas mitigation strategies.
Land-Use Transfer and Its Ecological Effects in Rapidly Urbanizing Areas: A Case Study of Nanjing, China
Authors: Zhou Yinqiao , Cao Wei , Zhou Jiandong
Published: December 2024

Rapid transformations in land use and land cover (LULC) serve as critical drivers influencing the eco-environmental quality in swiftly urbanizing areas. This study aims to assess and analyze the land-use transfer in Nanjing, China from 2003 to 2023 and its effects on ecological environment quality, utilizing the land expansion intensity (En), the land use composite index (LUCI), the remote sensing ecological index (RSEI), and other models. The results show that (1) farmland and forestland decreased significantly, with forestland showing the largest decrease (−20.65%), while construction land showed the largest increase (98.70%), mainly from farmland; (2) the overall RSEI level in Nanjing was relatively high, with a slight decline in fluctuation in the past 20 years. The RSEI values of forest land (0.8786) and farmland (0.8318) were higher, while the construction land (0.3790) and unused land (0.3701) were lower; (3) there was significant correlation (p < 0.05) and spatial autocorrelation between land-use changes and RSEI changes. The RSEI of rural areas was better than that of urban centers. There was a significant negative linear correlation between RSEI and LUCI (R2 = 0.711), a significant positive correlation with the area proportion of farmland, forest land and water, and a significant negative correlation with the area proportion of construction land. (4) Predictions indicate continued declines in farmland and forestland, accompanied by further expansion of construction areas, and the RSEI will continue to decline. It is suggested that forestland and farmland should be protected in the future, the expansion of construction land should be restrained, urban construction and ecological protection should be balanced, and the sustainable and high-quality development of rapid urbanization areas should be maintained by accurate land-use planning.
A Systematic Bibliometric Review of Fiscal Redistribution Policies Addressing Poverty Vulnerability
Authors: Li Yali , Marquez Ronald , Ye Qianlin , Xie Luhua
Published: December 2024

The elimination of poverty in all its forms is the first global goal of the United Nations’ 2030 Agenda for Sustainable Development. Achieving this goal is recognized as a long-term process that is complicated by persistent vulnerabilities stemming from factors such as natural disasters, food insecurity, health challenges, educational disparities, and social inequality. This systematic bibliometric review provides a comprehensive survey of the impact of social protection-based policies in mitigating poverty vulnerability, focusing on selected countries and regions, including America, Europe, Oceania, and part of Asia and Africa. Our analysis reveals that 81% of the studies examine poverty vulnerability from a single dimension, predominantly focusing on food security and nutrition (23%), climate change shocks (18%), and health-related vulnerabilities (14%). The geographic distribution indicates that the United Kingdom and the United States lead research in this field, contributing 36 and 32 papers, respectively, followed by China (16 papers), South Africa (15 papers), and Canada (10 papers). The results indicate that these fiscal redistribution policies significantly contribute to reducing poverty and inequality and have positive impacts on other Sustainable Development Goals (SDGs), particularly SDG 1 (No Poverty), SDG 2 (Zero Hunger), SDG 3 (Good Health and Well-being), and SDG 10 (Reduced Inequalities). However, notable gaps remain, especially regarding the integration of these policies with environmental sustainability goals like SDG 13 (Climate Action), which are addressed in only a minority of studies. This study concludes by recommending the adoption of more holistic and integrated policy frameworks that bridge the gap between social protection and environmental sustainability, thereby advancing the entire 2030 Agenda for Sustainable Development.
Enhancing Resilience and Coordination in Sustainable Logistics Service Supply Chains Through Integrated Investment Contracts
Authors: He Chan , An Qianru , Xu Xu , Zhang Guoshuai
Published: December 2024

Within the logistics service supply chain, where logistics service integrators and providers collaborate, the role of integrators in orchestrating resources and enhancing supply chain efficiency is pivotal. To motivate logistics service providers to invest in logistics capacity, thereby maintaining supply chain resilience and achieving coordination, a joint contract incorporating cost and benefit sharing is proposed in a novel Stackelberg game model. By analyzing the behavior of various decision-making models—centralized, coordinated, and decentralized—in supply chains, we find that the proposed Stackelberg game model effectively correlates higher investment levels with increased supply chain resilience. The coordination mechanism significantly improves both the level of resilience and the investment amount, leading to enhanced overall profitability. Sensitivity analysis reveals the impact of market pricing, demand stockout penalty costs, and substitute demand prices on these outcomes. This research contributes a new theoretical framework and practical insights into supply chain coordination and investment strategies.
The Viscosity of Liquids in the Dual Model
Authors: Peluso Fabio
Published: December 2024

In this paper, a reliable model of the viscosity in liquids in the dual model of liquids (DML) framework is developed. The analytical expression arrived at exhibits the correct T–dependence Arrhenius-like exponential decreasing trend, which is typical of Newtonian simple fluids. The model is supported by the successful comparison with both the experimental values of the viscosity of water, and with those related to the mechano-thermal effect in liquids under low-frequency shear, discovered a few years ago, for which the first-ever theoretical interpretation is given by the DML. Moreover, the approach is even supported by the results of numerical models recently developed, that have shown that dual liquid models, such as the DML, provides very good agreement with experimental data. The expression of viscosity contains terms belonging to both the subsystems constituting the liquid, and shows an explicit dependence upon the sound velocity and the collective vibratory degrees of freedom (DoF) excited at a given temperature. At the same time, the terms involved depend upon the Boltzmann and Planck constants. Finally, the physical model is coherent with the Onsager postulate of microscopic time reversibility as well as with time’s arrow for macroscopic dissipative mechanisms.
Epsilon Toxin from Clostridium perfringens Induces the Generation of Extracellular Vesicles in HeLa Cells Overexpressing Myelin and Lymphocyte Protein
Authors: Dorca-Arévalo Jonatan , Santana-Ruiz Antonio , Torrejón-Escribano Benjamín , Martín-Satué Mireia , Blasi Juan
Published: December 2024

Epsilon toxin (ETX) from Clostridium perfringens is a pore-forming toxin (PFT) that crosses the blood–brain barrier and binds to myelin structures. In in vitro assays, ETX causes oligodendrocyte impairment, subsequently leading to demyelination. In fact, ETX has been associated with triggering multiple sclerosis. Myelin and lymphocyte protein (MAL) is widely considered to be the receptor for ETX as its presence is crucial for the effects of ETX on the plasma membrane of host cells that involve pore formation, resulting in cell death. To overcome the pores formed by PFTs, some host cells produce extracellular vesicles (EVs) to reduce the amount of pores inserted into the plasma membrane. The formation of EVs has not been studied for ETX in host cells. Here, we generated a highly sensitive clone from HeLa cells overexpressing the MAL-GFP protein in the plasma membrane. We observed that ETX induces the formation of EVs. Moreover, the MAL protein and ETX oligomers are found in these EVs, which are a very useful tool to decipher and study the mode of action of ETX and characterize the mechanisms involved in the binding of ETX to its receptor.
Can Solidago gigantea Impede the Establishment of a Riparian Forest Along a Restored River Section?
Authors: Becker Isabell , Paul Miriam , Egger Gregory
Published: December 2024

Riparian softwood forests support numerous ecological functions and high biodiversity. In the context of the LIFE+ Traisen project, a non-regulated new riverbed for the lower Traisen River (“New Traisen”) was created within an artificially lowered floodplain corridor. Using vegetation monitoring from 2014 to 2021, we determined (i) the role of Solidago gigantea in the establishment of softwood forests, (ii) the habitat parameters (such as flooding height, fine substrate layer thickness, and vegetation cover) that impact the establishment and growth of woody plants, and (iii) the successional phase at which woody plants become established, as well as the potential creation of new germination habitats. During early succession, the softwood species, as light-tolerant pioneer species, colonized the open sites together with S. gigantea and subsequently established a floodplain softwood forest. Unexpectedly, we observed negative forest development only when the S. gigantea cover exceeded 90%. Neither the habitat parameters nor S. gigantea cover significantly impacted tree occurrence. However, we highlight the need for optimum habitat parameters for softwood forest development in early succession phases, ideally before S. gigantea forms dense, monospecific stands. Tailored monitoring strategies are needed to guide the succession of such semi-aquatic habitats toward the development of the desired habitat type.

Tryptophan-like fluorescence (TLF) is a key indicator of water contamination, particularly of microbial origin and biodegradable organic compounds. This study introduces an Internet of Things (IoT)-enabled portable device (IoT-TLF-PD) for real-time monitoring of microbial quality and biochemical oxygen demand (BOD5). The device was tested using surface water (S1), secondary wastewater (S2), and final wastewater effluents (S3). Results showed significant correlations between TLF intensity, Escherichia coli (E. coli) counts, and BOD5, with R2 values of 0.77 (S1), 0.61 (S2), and 0.76 (S3) for BOD5, and 0.60 (S2) to 0.68 (S3) for E. coli. Considering various water samples, a strong correlation was found between E. coli and BOD5 with TLF intensity normalized by total organic carbon (TOC) concentration (TLF intensity/TOC). The R2 value for E. coli was 0.92, and for BOD5, it was 0.77. This indicates the necessity of accounting for organic matter concentration when interpreting TLF intensity in water quality assessments. The study confirmed the potential of the IoT-TLF-PD to serve as a cost-effective, real-time indicator for assessing water quality, especially for detecting microbial contamination. This technology offers a valuable tool for environmental monitoring and water management.

Published: December 2024

In first review we considered the problems of creation of sturgeon
broodstocks in freshwater with full exclusion of marine phase. Several species
of salmonids (trouts) which easily change their life stategy (sea trout/brown
trout Salmo trutta, steelhead/rainbow trout, brook trout Salvelinus fontinalis
and other chars) also could be grown in fresh water up to definitive sizes and
maturation. Atlantic salmon differs from above species. In present article the
intraspecific structure of Atlantic salmon and its life strategies (anadromous,
potamodromos and riverine/residential), development of methods of artificial
propagation of salmonids and possibilities of Atlantic salmon growing in conditions
of freshwater farm are considered. Three types of broodstocks could
be created — sea-run (wild), captive (grown from wild smolts) and domestic
(grown from eggs) ones. The creation of domestic freshwater broodstock of
Atlantic salmon is more complicated in comparison with “trouts” because of
precocious maturation of great percent of males and low quality of mature
germinal cells in males and females. The other negative features of domestic
breeders are decreased genetic variability, increased straying and reduced
reproductive success. So commercial aquaculture uses traditional scheme of
transfer of large smolts (near 100 g) to sea cages. Conservation aquaculture
prefers wild non-resident breeders. Atlantic salmon is characterized by riverspecific
broodstocks, so each river should have its own broodstock. As a result,
domestic broodstock of Atlantic salmon in conservation aquaculture could be
used only as last measure when all other possibilities are already exhaused.

Authors: Abata Checa Fanny Mercedes , Pullupaxi Tamayo Febe Paola
Published: December 2024

During the pandemic, the Ministry of Education implemented virtual teaching strategies using digital platforms and applications. WhatsApp emerged as a tool to support English language instruction in virtual classes. This study aimed to explore teachers' perceptions regarding the use of WhatsApp for teaching English as a foreign language. A qualitative methodology with a descriptive and case study design was employed, collecting data through a non-structured interview with two English teachers. Findings from a Bachelor's degree project revealed that WhatsApp was primarily utilized for providing task feedback, sharing assignments and resources, and facilitating communication with students and parents. The most practiced skills were writing, reading, and pronunciation. However, it was concluded that while WhatsApp enabled quick communication, its effectiveness as an educational tool for teaching English was limited due to teachers' lack of training in leveraging WhatsApp for pedagogical purposes.

IS IT ALREADY POSSIBLE TO LAUGH? (THE CRISIS OF MODERN AESTHETICS AND THE CHANCE OF A NEW ART)
Authors:   St. Petersburg State University, Sekatski А.K.
Published: December 2024

The article analyses the transformations of aesthetic space that are currently occurring, which in many ways shape the very image of modernity and enable us to anticipate the potential future trajectory of Western civilisation. The aesthetics of opus, which emerged in the wake of the Renaissance, has experienced a significant decline. The genre markup, which served as a conductor and sometimes a superconductor for high art, has been captured by social engineering and transformed through AI (so far an 'inclusive inquisition' rather than artificial intelligence) into a set of direct, unambiguous instructions for assembling a new, simplified subject. Concurrently, the previously marginalised trend of kitsch, which currently dominates under the designation of "mimi-mimi" aesthetics, has received a substantial boost, manifesting both on the vast expanses of the Internet and in "raw life." It is, therefore, paradoxical that it is aesthetics which today serves to defend the simple aesthetic needs of man in the face of the capitulation of the former high art. The article also puts forth an alternative trajectory for art, one that is associated with the formation of a new aesthetics of free elements. This entails the reappropriation of certain practices that have been previously eschewed by the scientific community, such as those employed by naturalists and polar explorers. These practices can then be repurposed for a novel transformation of the world, with the aim of bestowing vision upon the hitherto "blind elements"
THE PHENOMENON OF FANTASY: HOW THE GENRE BECAME ONE OF THE PILLARS OF MODERN CULTURE

Published: December 2024

In the 20th century, a new artistic genre, fantasy, separated from science fiction and gained independence. Many cultural figures began to turn to the aesthetic ideals of antiquity, the Middle Ages and the European Renaissance, which, in turn, became a synthetic ideological basis for the formation of a new genre. This article analyzes the specifics of the fantasy genre and its place in modern mass culture. The main paths of development of the fantasy genre from the early 20th century to the early 21st century are defined and analyzed, which combines the syncretism of traditional trends of the aristocratic epic, historical novel and folklore. Scenarios for the transformation of modern fantasy industries into a tool for proclaiming, visualizing and studying complex themes of morality and identity are also explored. The genre fully reflects the palette of modern socio-cultural problems,and its global popularity largely contributes to intercultural exchange. Of particular interest are works that have a literary source and subsequent adaptation (film, video game), using which their artistic dynamics can be traced. The results of the studyoffer new views on modern intercultural interaction. A comprehensive cultural approach to the study of fantasy allows us to go beyond the narrow framework of such an art form as literature and trace its active and successful expansion into various spheresof culture: cinema, anime and computer games.
GENERATIVE DESIGN AND CYBERNETIC ANTHROPOLOGY OF ARTIFICIAL INTELLIGENCE
Authors:   Belarusian National Technical University, Loiko А.
Published: December 2024

The convergence of generative design practices with cybernetic anthropology of artificial intelligence is explored. A transformation of the main forms of design activity took place as part of the convergence. One of the aspects was the topic of modernizingdesign methodology, considering the preservation of its core professional competencies and the subject ontology of creative activity. Another aspect of consideration is focused in the article on the development of cybernetic anthropology of artificial intelligence, the product of which was synthetic people. Their main function is communication. It was formed by the practice of using chatbots and digital assistants in the functions of administrators and consultants. A new direction in the cybernetic anthropology of artificial intelligence has become the formation of generative functions in computer programs through deep machine learning. This technological trend raises questions about employment prospects and copyright and related rights to creative works.
