Post-process correction improves the accuracy of satellite PM2.5 retrievals
Authors: Porcheddu Andrea , Kolehmainen Ville , Lähivaara Timo , Lipponen Antti
Published: September 2024

Abstract. Estimates of PM2.5 levels are crucial for monitoring air quality and studying the epidemiological impact of air quality on the population. Currently, the most precise measurements of PM2.5 are obtained from ground stations, resulting in limited spatial coverage. In this study, we consider satellite-based PM2.5 retrieval, which involves conversion of high-resolution satellite retrieval of aerosol optical depth (AOD) into high-resolution PM2.5 retrieval. To improve the accuracy of the AOD-to-PM2.5 conversion, we employ the machine-learning-based post-process correction to correct the AOD-to-PM conversion ratio derived from Modern-Era Retrospective analysis for Research and Applications, Version 2 (MERRA-2) reanalysis model data. The post-process-correction approach utilizes a fusion and downscaling of satellite observation and retrieval data, MERRA-2 reanalysis data, various high-resolution geographical indicators, meteorological data, and ground station observations for learning a predictor for the approximation error in the AOD-to-PM2.5 conversion ratio. The corrected conversion ratio is then applied to estimate PM2.5 levels given the high-resolution satellite AOD retrieval data derived from Sentinel-3 observations. The region of study is central Europe during the year 2019. Our model produces PM2.5 estimates with a spatial resolution of 100 m at satellite overpass times with R2 = 0.55 and RMSE = 6.2 µg m−3. The corresponding metrics for monthly averages are R2 = 0.72 and RMSE = 3.7 µg m−3. Additionally, we have incorporated an ensemble of neural networks to provide error envelopes for machine-learning-related uncertainty in the PM2.5 estimates. The proposed approach can produce accurate high-resolution PM2.5 data that can be very useful for air quality monitoring, emission regulation, and epidemiological studies.
Geomorphic expressions of active rifting reflect the role of structural inheritance: a new model for the evolution of the Shanxi Rift, northern China

Published: September 2024

Abstract. Many rifts are influenced by pre-existing structures and heterogeneities during their evolution, a process known as structural inheritance. During rift evolution, these heterogeneities may aid rift nucleation, rift growth, and the segmentation of faults; encourage the linkage of various segments; or even inhibit the formation of faults. Understanding how structural inheritance influences early rift evolution could be vital for evaluating seismic risk in tectonically active areas. The Shanxi Rift in the north of China is an active rift system believed to have formed along the trend of the Proterozoic Trans-North China Orogen; however, the influence of these pre-existing structures on the present-day rift architecture is poorly understood. Here, we use tectonic geomorphological techniques, e.g. the hypsometric integral (HI), channel steepness (ksn), and local relief, to study the evolution of the Shanxi Rift and identify areas of higher tectonic activity. We found that the HI was less sensitive to lithology and more valuable in evaluating the tectonic signal and that activity is concentrated in two rift interaction zones (RIZs) formed between the Xinding, Taiyuan, and Linfen basins. We then evaluated the relationship between the active faults and mapped pre-existing structures, finding that many faults formed parallel to inherited structures, while faults in the RIZs often cross-cut these structures. Based on these observations, we propose a new model for the evolution of the Shanxi Rift, where inherited structures play an important role in the initial segmentation of the rift, which, in turn, controls the development of the RIZ structures.

“Ligato alla greca”. Greek-style bookbindings in early modern Venice and beyond
Authors: Gialdini Anna
Published: September 2024

Binding books “in the Greek manner” (“alla greca”, but also “al greco”, “alla grechessa”), imitating and replicating Byzantine techniques, was one of the practices associated with “Greekness” in Italy and other parts of western Europe in the early modern era. This book analyses the trends, patterns, and contexts associated with making Greek-style bindings in early modern Venice and elsewhere in western Europe between the 1450s and the end of the sixteenth century. It considers how techniques evolved over time as well as production and consumption practices: what kinds of manuscripts and printed books received Greek-style bindings, who made them, who collected them, and what meanings the bindings themselves conveyed. Coming into fashion at a time of major changes (coinciding with the fall of Constantinople, the Greek diaspora, and the coming of printing), in western Europe Greek-style bindings at times signified antiquarianism, exoticism, luxury, or a proximity to Greek culture. Through the analysis of several hundred specimens in the style and of documentary and visual sources, this book explores how a specific instance of material culture served a number of purposes and self-fashioning strategies for bibliophiles, collectors, and intermediaries alike within the context of Renaissance cultures; it also features a census of all known bindings in the style made in western Europe.

Authors: Sargsyan Arman , Harutyuny6an Armen
Published: September 2024

This study provides an overview of traffic control methods using automated traffic control systems (ATCS). The main approach highlighted during the analysis is the application of rigid multi-program management, including a library of coordination programs. The study also found a dependence of the period of operation of each coordination program on the state and intensity of traffic flow (TF), noting an increase in the period of stationarity with an increase in the intensity of TF. Based on the system analysis, a mathematical dependence of the control parameter on the intensity affecting the efficiency of TF management is proposed. The results obtained can be applied to optimize the operation of the automated control system and develop effective traffic management strategies.

Facilitators and barriers for working beyond statutory pension age: A prospective cohort study across 26 European countries
Authors: Andersen Lars Louis , Calatayud Joaquín , Núñez-Cortés Rodrigo , Polo-López Ana , López-Bueno Rubén
Published: September 2024

OBJECTIVE: The aging population of European countries highlights the need for extended working lives. This study aims to investigate facilitators and barriers for working beyond the statutory pension age (SPA).

METHODS: Using data from waves 1, 2, 4–9 of the Survey of Health, Ageing and Retirement in Europe (SHARE) (2004–2022), we followed 9131 workers with a mean age of 56.9 [standard deviation (SD) 3.5] years from 26 European countries until they surpassed the SPA for their respective country, sex and year of participation. Using robust Poisson regression, we modelled the prospective association of work factors, lifestyle, health, and demographics at baseline with working at least one year beyond the SPA.

RESULTS: Participants were followed for 9.5 (SD 3.9) years. After surpassing the SPA by at least one year, 18% were still working. Among the work factors, opportunities for skill development [risk ratio (RR) 1.20, 95% confidence interval (CI) 1.07–1.34] and recognition at work (RR 1.13, 95% CI 1.01–1.26) facilitated working beyond SPA, while time pressure (RR 0.89, 95% CI 0.81–0.97) and poor prospects for job advancement (RR 0.76, 95% CI 0.70–0.83) were barriers. For the other factors, smoking was negatively associated with working beyond the SPA, while living in the northern part of Europe, higher level of education, and being divorced or separated were positively associated with working beyond the SPA.

CONCLUSION: This prospective cohort study across 26 European countries identified four modifiable work factors that influenced working beyond the SPA. Addressing modifiable barriers and facilitators at the workplace and through public health initiatives could help extend working lives in Europe.
Analysing Photovoltaic Grid-Connected H5 Inverter with Artificial Intelligence for Induction Motor Load Testing and Evaluation
Authors: B. Rajapandian, G.T. Sundarrajan
Published: September 2024

Recent advancements in transformerless photovoltaic (PV) grid-connected inverters have positioned them as a prominent technology for distributed PV power generation systems. This is attributed to their demonstrably superior efficiency, reduced cost, and compact size. Conversely, they are susceptible to common-mode currents, leading to significant electromagnetic interference and security risks, thereby compromising system reliability. We introduced an enhanced H5 variant topology, termed H5-D topology, which integrates a clamping diode to mitigate common-mode voltage fluctuations. The paper presents the simulation results comparing both topology’s configurations, with a focus on the H5-D topology’s efficiency in suppressing common-mode currents. Additionally, experimental prototypes were constructed and evaluated for both the original and the H5-D configurations topology. The results unequivocally demonstrate the superior performance of the H5-D topology. The experimental findings corroborate the effectiveness of the recommended/suggested topology in addressing current issues related to common-mode issues, thereby enhancing the reliability and performance of photovoltaic inverter systems.

Published: September 2024

La industria del pellet en Chile contribuye a la diversificación de la matriz energética y a la reducción de la contaminación ambiental, pero enfrenta desafíos relacionados con la disponibilidad y calidad de la materia prima, así como la necesidad de normativas estrictas y obligatorias que aseguren la calidad del producto. El crecimiento del número de plantas productoras de pellet, derivado del aumento de la demanda de este biocombustible, originada por programas de fomento al recambio de calefactores y cambios culturales en el consumidor, ha requerido de una adecuada disponibilidad de biomasa forestal, tanto en calidad como en cantidad, evidenciándose episodios de puntuales de escasez que han afectado su disponibilidad en el país. Para minimizar esos episodios de escasez se están desarrollando diversas iniciativas abordadas en la Mesa de pellet desarrollada por el Ministerio de Energía durante el año 2023, de modo de favorecer al consumidor. Entre ellas se incluye el monitorear las importaciones de pellet, de manera de asegurar el abastecimiento, siendo de interés para productores, usuarios y entidades relacionadas, disponer de información del pellet que ingreso al país durante el último año. Por lo mismo, se realizó una búsqueda de antecedentes de los niveles de importación de pellet en el país durante el año 2023, analizando su tendencia y estacionalidad como serie de tiempo. Los resultados del análisis señalan que, durante el año 2023, la cifra de importación fue de 13.699 toneladas, representando el 84,6% del total de pellet ingresados al país desde el año 2014 al 2023. Respecto de la estacionalidad, los análisis iniciales señalan que las fluctuaciones se repiten a través del tiempo, con meses específicos donde el comportamiento de los valores de importación se repite de manera anual.

Do modern theories of economics need a methodological culture of political and economic research?
Authors: Karaseva Lyudmila
Published: September 2024

In conditions when the main meaningful meaning of the choice of the Russian way forward is formed, the problem of the formation of economic theory, adequate to the modern stage of development of national and world economies, whose economic systems are in a state of deep transformation, is actualized more than ever. Economic science in the “new reality” is faced with such phenomena as the socialization of the economic life of modern society, the economization and financialization of politics and the politicization of the economy in the context of the globalization process, again highlighting the question of the place and directions of the development of political economy in economic science. Therefore, there is a serious question about the paradigm of modern economic theory, which would absorb the reflection of these new processes. For this reason, this material is a kind of attempt to integrate into the ongoing discussion about the place and development of political economy, about expanding the subject of economic theory [1; 2; 3; 4; 5; 6; 7; 8], offering an author’s methodological perspective on the principal issues of discussion. Participation in the discussion is also important from the point of view of the position of research teachers leading disciplines included in one capacity or another in economic theory. And this means - developing the criterion-value socio-economic worldview of future specialists, their methodological culture of research.
Some insights from analyzing the theory and practice of economic management in a hard-fought battle with neoliberalism
Authors: Gorgola Evgeniy , Hudyakov Dmitriy
Published: September 2024

This article attempts to systematically study the pseudo-market economy of the neoliberal type, which was operating in the country and which was actually subordinated to the interests of globalists with the help of financial and foreign economic instruments. On the basis of institutional analysis of the results of practical implementation of theoretical postulates of economic theory, the real efficiency (or rather, inefficiency) of the country’s economy, built as a raw materials appendage, as a technological backyard of developed countries, is clarified, and the conclusion about the need to restructure the entire economic mechanism, focused on the unconditional priority of national interests in socio-economic development is substantiated. The authors prove that real progress in the Russian Federation is associated with the transition to strategic management of the national economy, strengthening of centralized processes that allow to concentrate available resources on the main directions of economic and social growth, as well as strengthening the defense capability of the state in the conditions of hybrid war of the collective West against Russia. This is what should be the focus of the emerging model of management of the national economy, capable not only to resist economic pressure, but also to really ensure the achievement of national goals.
Impact of labor migration on the technological development of EAEU countries
Authors: Shkiotov Sergey , Markin Maksim
Published: September 2024

The formation of a single labor market in the EAEU creates new opportunities and risks for national economies: the free movement of labor resources within the integration association affects not only the level of wages or employment, but also leads to more complex, complex consequences for donor and recipient countries. Using correlation analysis, the paper verifies the hypothesis that the reverse spillover effect associated with the return of migrant workers to their home countries contributes not only to the growth of value added in labor donor countries, but also stimulates demand for new technologies and services, which ultimately leads to an increase in the level of technological development of EAEU countries. As a result of the analysis, it was found that there is no statistically significant relationship between the variables under study – labor migration does not have a significant impact on the level of technological development of the EAEU countries. The results of the study can be used to develop a strategy of technological development of the EAEU countries, taking into account the parameters of external labor migration.
Implications of Transport Poverty and Social Exclusion in Lagos State Transportation System
Authors:   University of Lagos, Nigeria, Ege Emmanuel , Olujimi Samson ,   University of Lagos, Nigeria, Chilaka Edmund ,   Liverpool John Moores University UK
Published: September 2024

The link between transportation and social inclusion is well-established. Poor access to transportation services makes goods and services inaccessible, further marginalizing those who do not own motor vehicles. Sociologists look at social exclusion from these dimensions - poverty, inequality, lack of decent and accessible public services, inadequate public transport, the welfare and benefits system, and lack of good housing. These inequalities existed in our transportation system before the introduction of new technologies and business models, and they are exacerbated by present-day social disadvantages. This study examined the transport poverty metrics and housing quality index in some selected parts of Lagos Nigeria. The sample for the study was taken from six (6) locations with four hundred and eighty (480) questionnaires i.e., eighty (80) for each location. There were one hundred and sixty-eight (168) female respondents and three hundred and twelve (312) male respondents with four stated objectives and data for the study was collected through questionnaires. The research hypothesis and questions were tested using the Mann Whitney-U Test Analysis and Analysis of Variance ANOVA to compare differences between the Suburban neighborhood group and the Central neighborhood group. The findings show that households in the Central neighborhood group tend to live closer to convenient transportation options and don't have to drive/travel far to obtain basic services like hospitals, grocery stores, and places of work, but they pay higher housing rentage even when the transport externalities are minimal while the Suburban neighborhood group spend an average of more than 34.7% of their income on transportation and tend to travel farther and lack access to good transportation alternatives. However, one of the recommendations is that waterways transportation around the Suburban group must be revamped with realistic fares to attract people and reduce stress on road transport.

Methods: Using the Global Asthma Network questionnaires, this study sampled 2646 children, of which 1210 were aged 6–7 years and 1436 were aged 13–14 years in addition to 3831 adult parents or guardians. The STROBE guidelines were used to ensure the reporting of this cross-sectional study. Univariate and multivariate logistic regression were used to produce the odds ratio for the various risk factors and associated factors, respectively. Multiple associations and risk factors for each of the three diseases were reported.

Results: Based on the outcome of a multivariate logistic regression, being born in Qatar was the only risk factor present across all three diseases. Being male, wheezing ever, wheezing after exercise, and having eczema were other risk factors reported for asthma. Being in the older age group, wheezing ever, and having hay fever were other risk factors reported for allergic rhinitis.

Conclusion: The study concluded that further evaluation into associated and risk factors for asthma, allergic rhinitis, and eczema is warranted in the future.

Dynamics of Language Processes, Literary Language Norms and Phenomena Under Reconstruction Or Crises of Communication In Bulgarian Society]
Authors: Milanov Vladislav
Published: September 2024

The article traces the dynamics of several linguistic processes related to: the use of diminutive forms in contemporary Bulgarian language as dynamics and as a challenge of mastering these forms in Bulgarian language as a native and as a foreign language; the development of the grammatical category of definitiveness of the names of institutions, placing the emphasis on the vacillations of the literary requirement by means of the article morpheme to clearly underscore that a single referent is what is meant and this singleness is grammaticaly unfolded by using article morphemes; the processes of derflexivization of verbs like ‚be afraid of‘, ‚be ashamed‘ of, ‚smile‘, among others.

The article presents the process of communication between the coach and the trainees during swimming lessons. The focus falls on verbal communication through the use of terminology specific to the sport and non-verbal communication through the implementation of particular signs. Swimming is a sport that is a 465 Биляна Рангелова, Красимира Дешева, Петър Тодоров combination of specific physical movements of the body and a specific technique for breathing and exhaling in a non-human environment – water. Furthermore, swimming is suitable for practicing by children with special educational needs and disabilities (SEND), due to the fact that it allows the achievement of social integration, on the one hand, and the development of the physical condition of the body, on the other. Practicing the sport of swimming poses various challenges, as the person with SEND may have one or more disabilities that require an individual approach. Practicing the sport in an aquatic environment further complicates the communication between a coach and a trainee. In this respect, both verbal and non- verbal communication can be used. For instance, with visually impaired children, communication involves verbal commands and instructions that must be clear and understandable. For children with impaired hearing and/or speech, communication is carried out through gestures and facial expressions similar to sign language. The article will review the literature on the problem and will provide practical examples of the application of different types of communication during swimming lessons. The article has been written as part of the activities of the project “Innovative system of verbal and non-verbal means of communication within physical education and sports activities for children with SEND”, financed by the SUMMIT Sofia University Marking Momentum for Innovation and Technological Transfer Project.
Integrating Gamification with BIM for Enhancing Participatory Design

Published: September 2024

The combination of gamification and Building Information Modeling (BIM) can be described to support user participation, decision-making, and collaboration in design contexts. Within this aim, this paper presents a literature review on the potential of using gamification in the BIM framework to create immersive participatory design environments. Active involvement of stakeholders by the corporation of gamified components such as challenges and interactive simulations into the design process enables better decisions and enhances user experience. Further, gamification integrated into BIM brings the potential to improve user behavior and decision-making at all stages of the design lifecycle but also the limitations and challenges. It can encourage stakeholder interaction and provide real-time input allowing various stakeholders to make meaningful contributions towards sustainability goals. This study examines recent developments and trends in extended reality (XR), augmented reality (AR), and virtual reality (VR). These advances significantly enhance gamified Building Information Modeling (BIM) environments as being immersive. In addition, it points out some challenges, and ethical concerns encountered with these technologies. Furthermore, this paper highlights some tools and their advantages, disadvantages, pricing, and key elements. Designers can create interactive experiences by combining these technologies with virtual and physical environments. BIM environments powered by gamification can be used in BIM workflows to reach their full potential in shaping future design practices. These include ways to advance cooperative design processes by creating immersive spaces for different stakeholders’ interests and keeping up with emergent technology.

Published: September 2024

Background: The posterior interosseous nerve (PIN) is at risk of iatrogenic nerve injury during elbow surgery when using a lateral or posterolateral approach. Results of cadaveric studies indicated that maintaining forearm pronation throughout the surgery can help move the PIN away from the surgical window. However, in vivo dynamic migration of the PIN in response to changes in the elbow and forearm position is unclear. This study aimed to clarify the in vivo dynamic migration pattern of the PIN in response to changes in the elbow and forearm position using ultrasound imaging.Methods: This study included 43 upper extremities of 22 healthy volunteers (16 females; mean age, 29 years). Using ultrasound imaging, we measured the shortest distance from the radial head (RH) to the point where the PIN crossed the lateral aspect of the radial axis in six positions of the elbow and forearm: 90° forearm supination, 90° pronation, and neutral forearm position, each at 135° of elbow flexion and 0° of elbow extension.Results: The RH-to-nerve distance was greater during elbow extension than during elbow flexion regardless of the forearm position. However, the maximum migration distance was 3.5 mm when transitioning from elbow extension and forearm pronation (25.1 mm) to elbow flexion and forearm supination (21.6 mm).Conclusions: Although forearm pronation may help move the PIN away from the surgical window, care should be taken not to injure the nerve when performing elbow surgery using a lateral or posterolateral approach.Level of evidence: III.
