Authors: Wang Yidong , Song Rui , He Shiwei , Song Zilong
Published: June 2022

A multi-station high-speed railway hub is the interaction of multiple high-speed railway lines, and its operation determines the efficiency of the whole network. In this study, we focus on the train routing problem for a multi-station railway hub and propose a flexible scheme to improve the capacity utilization. Based on the flexible scheme, a mixed-integer programming node-arc model is formulated to minimize the total cost of train and passenger routes. Specifically, for diversifying the train routes, we consider the individual train rather than the train flow as the basic unit, which differs from the approach in previous studies. For each train route, in addition to the macro-scale route between stations, the micro-scale track allocation inside stations is also considered. Afterward, the optimization solver Gurobi is used to solve the model and obtain the optimization scheme. A case study based on real data from the Zhengzhou railway hub in China is implemented to evaluate the effectiveness of the optimization model. By comparing the optimization scheme with the fixed scheme and the sequential scheme, the results show our method could reduce the total cost by 29.35% and 22.58%, and the line and track capacity utilization of the optimization scheme is more reasonable. We provide some suggestions to help railway managers improve the operation efficiency and service quality of multi-station high-speed railway hubs.

Published: June 2022

The carbon emissions of the construction industry pose a significant challenge to implementing China’s carbon peaking and carbon neutrality goals. This study considered how to promote stable green building (GB) development. First, evolutionary game theory (EGT) was applied to examine the interaction mechanism of complex behaviors between governments and developers, constructing two scenarios of static and dynamic subsidies. Second, we proposed the ideal state where the government does not give funding subsidies and developers take the initiative to build GBs. On this basis, the simulation method was used to verify the game models and primary conclusions. Finally, a detailed sensitivity analysis of selected parameters was undertaken. The results demonstrated that subsidy policy phase-outs could help in the development of GBs; the probability of an ideal state was positively correlated with government supervision and punishment, and it was negatively correlated with government funding subsidies. The research results can be used as a reference for the government to improve incentive measures and decision support for stakeholders to adjust their strategies.

Published: June 2022

In order to reveal the influence law of coal seam dip angle on the stability of the surrounding rock of the gob-side coal–rock roadway in a gently inclined coal seam (GCRGICS), the deformation characteristics of the surrounding rock under four different coal seam dip angles of this kind of roadway were studied by field investigation, theoretical analysis and numerical simulation. The results showed that, with the increase of the coal seam dip angle, the amount of the roadway roof subsidence and the deformation of the upper and lower side arc triangle coal along the coal–rock interface increased, and the maximum deformation was 479 and 950 mm, respectively, and the maximum slip deformation area gradually shifted from the upper side arc triangle coal to the lower side arc triangle coal. The asymmetric deformation characteristics of the surrounding rock became more and more obvious. The asymmetric deformation rate of the GCRGICS showed a V-shaped variation relationship with the coal seam dip angle, when the coal seam dip angle was 10°, the asymmetric deformation rate was the minimum, only 1.1%. The plastic zone of the surrounding rock expanded with the increase of the coal seam dip angle, and the new extension range was mainly located in the roof area of the roadway.

Published: June 2022

With the extensive use of antibiotics, antibiotics, and antibiotic resistance genes (ARGs), contamination in the water environment is becoming severe in recent years. This study examined the distribution characteristics of sulfonamide antibiotics and resistance genes in the urban section of the Yitong River in autumn and winter. In addition, the correlation between them and water quality parameters was analyzed using Pearson correlation analysis. The surface water from the Yitong River was sampled in September and November for this experiment. The results of 32 samples showed that seven sulfonamides were detected in the surface water and sediments of this reach, and the concentrations were generally at the levels of ng/L and ng/g. The total concentration range was 11–161 ng/L and ND-85.7 ng/g. The concentrations of different antibiotics were similar in autumn and winter, and the concentration of sulfamethoxazole (SMX) was higher than that of other antibiotics. The results of the Risk Quotients (RQs) showed that SMX and sulfadiazine (SDZ) had moderate acute risk to the corresponding sensitive species in river water, sulfapyridine (SPD) and sulfisoxazole (SIZ) had low acute risk, while the rest had no risk. The total bacterial abundance in surface water and sediment was in the range of 104–105 copies/mL and 108–1011 copies/g, respectively. The detection rates of three sulfonamide resistance genes were 100%; the relative abundance was in the range of 10−3–10−1 copies/16S rRNA, and sul1 was the primary resistance gene. The results of correlation analysis showed that there was a significant positive correlation between sulfamethazine (SMZ), sulfathiazole (STZ), and SIZ and water quality indexes such as total nitrogen (TN) and total phosphorus (TP), ammonia nitrogen (NH3-N) and chlorophyll a (Chl-a). The river‘s change of water quality environment could significantly affect the antibiotics’ spatial distribution characteristics and content. The higher the level of nutrients, the higher the concentration of antibiotics. The abundance of sulfa resistance genes was positively correlated with the concentration of sulfa antibiotics. Frequent human activities can increase antibiotic concentration, leading to the production of more resistance genes induced by antibiotics, but the main reason for the formation of resistance genes was not apparent. Therefore, exploring the occurrence and pollution characteristics of antibiotics and ARGs in the environment of the Yitong River Basin in Changchun City and analyzing their sources, transmission, and ecological risks in the environment provided an essential scientific basis for pollution prevention and ecological protection of urban rivers in northern China.
Effectiveness Study on Online or Blended Language Learning Based on Student Achievement: A Systematic Review of Empirical Studies
Authors: Zhou Tong , Zhang Wei
Published: June 2022

The ubiquitous impacts resulting from the COVID-19 pandemic have profoundly changed the education sector and marked research interest in online or blended learning can be witnessed. As a pervasive learning activity of paramount significance, online language learning has aroused widespread attention. Nonetheless, few systematic reviews concerning the effectiveness of online language learning have been published. With the help of CiteSpace, this study systematically investigated 103 included articles from the SSCI of empirical studies from 44 journals for the purpose of filling the research gap in this field, providing a better understanding of the research trends, exploring effective ways to implement online language courses, and testifying to the ability of CiteSpace to track research hotspots. The findings show that effectiveness studies on online language learning principally focus on assisted tools (42.72%), instructional approaches (36.89%), and specific courses (20.39%). Lack of adequate cooperation among research institutions and the dominant position of online English learning (82.52%) can be witnessed. Despite the small sample size of 103 included articles, the validation of CiteSpace in terms of tracking the research trends or hotspots is confirmed. However, the proportion of each research focus is not compatible with the results of a comprehensive full-text analysis. This literature review also probes into various methods to measure effectiveness more scientifically and effective ways to implement online language courses. Theoretical as well as practical implications and future research directions are clarified.
Using K-Means Clustering in Python with Periodic Boundary Conditions
Authors: Miniak-Górecka Alicja , Podlaski Krzysztof , Gwizdałła Tomasz
Published: June 2022

Periodic boundary conditions are natural in many scientific problems, and often lead to particular symmetries. Working with datasets that express periodicity properties requires special approaches when analyzing these phenomena. Periodic boundary conditions often help to solve or describe the problem in a much simpler way. The angular rotational symmetry is an example of periodic boundary conditions. This symmetry implies angular momentum conservation. On the other hand, clustering is one of the first and most basic methods used in data analysis. It is often a starting point when new data are acquired and understood. K-means clustering is one of the most commonly used clustering methods. It can be applied to many different situations with reasonably good results. Unfortunately, the original k-means approach does not cope well with the periodic properties of the data. For example, the original k-means algorithm treats a zero angle as very far from an angle that is 359 degrees. Periodic boundary conditions often change the classical distance measure and introduce an error in k-means clustering. In the paper, we discuss the problem of periodicity in the dataset and present a periodic k-means algorithm that modifies the original approach. Considering that many data scientists prefer on-the-shelf solutions, such as libraries available in Python, we present how easily they can incorporate periodicity into existing k-means implementation in the PyClustering library. It allows anyone to integrate periodic conditions without significant additional costs. The paper evaluates the described method using three different datasets: the artificial dataset, wind direction measurement, and the New York taxi service dataset. The proposed periodic k-means provides better results when the dataset manifests some periodic properties.

Published: June 2022

Vibrating technological equipment for the introduction of piles and columns into the ground of construction foundations (named vibratory piling machines) is crucial in the process of building stable and resilient foundations for civil engineering, hydrotechnical construction, special construction (e.g., military constructions), bridges, roads and industrial platforms. During the works carried out by the construction companies in various geographical areas of Romania, particularities of the dynamic technological regimes influenced by the nature of the land were identified at the deep introduction of the construction elements in the form of piles or circular (tubular) columns. The results of applied research, rheological modeling and optimization of vibrating equipment, highlight the need for an analytical approach that takes into account the parametric variations of the elastic and damping characteristics of some categories of soils on the depth of piles or foundation columns. In this context, the paper presents the calculation model with the dynamic response for the vibrating equipment of insertion with disturbing forces of 200–1250 kN for piles or columns with lengths of 10–30 m. The novelty of the research study consists in the linear rheological model, which was adopted in the form of a Maxwell–Voigt–Kelvin schematic of the type (E-V)–(E|V), with a discrete variation in four values for stiffness and damping of the soil, as the piles or columns vibrate and advance in the ground foundation. Practical experience of the authors in the field of using vibrogenerators for the introduction of piles in various types of ground foundations led to the adoption of the rheological model with variable damping coefficients depending on the depth of penetration into the soil. The curves of the dissipated power confirm the experimental data obtained in situ, in accordance with the rheological indoor tests of the different types of soil foundations.

Radial acquisition with MOCCO reconstruction has been previously proposed for high spatial and temporal resolution breast DCE imaging. In this work, we characterize MOCCO across a wide range of temporal contrast enhancement in a digital reference object (DRO). Time-resolved radial data was simulated using a DRO with lesions in different PK parameters. The under sampled data were reconstructed at 5 s temporal resolution using the data-driven low-rank temporal model for MOCCO, compressed sensing with temporal total variation (CS-TV) and more conventional low-rank reconstruction (PCB). Our results demonstrated that MOCCO was able to recover curves with Ktrans values ranging from 0.01 to 0.8 min−1 and fixed Ve = 0.3, where the fitted results are within a 10% bias error range. MOCCO reconstruction showed less impact on the selection of different temporal models than conventional low-rank reconstruction and the greater error was observed with PCB. CS-TV showed overall underestimation in both Ktrans and Ve. For the Monte-Carlo simulations, MOCCO was found to provide the most accurate reconstruction results for curves with intermediate lesion kinetics in the presence of noise. Initial in vivo experiences are reported in one patient volunteer. Overall, MOCCO was able to provide reconstructed time-series data that resulted in a more accurate measurement of PK parameters than PCB and CS-TV.

Published: June 2022

Biocides based on chemical synthetic compounds have been commonly used to counteract damages caused by microorganisms on stone cultural heritage. However, in the last few years, the use of commercial and traditional biocides has been banned and/or limited due to their dangerous profile for the environment, as well as human and animal health. Natural products could be used as suitable alternatives for cultural heritage purposes, as they have low toxicity and stability compared with synthetic pesticides. Even if most of the investigated solutions have already shown promising results, their efficiency, ecotoxicological, and chemical features are poorly investigated. In this manuscript, we aimed to evaluate the ecotoxicological profile of four fungal metabolites—namely, cavoxin, epi-epoformin, seiridin, and sphaeropsidone—with potential antimicrobial properties for monumental artworks. A battery of ecotoxicological tests using Aliivibrio fischeri (bacterium), Raphidocelis subcapitata (alga), Raphanus sativus L. (macrophyte), Daphnia magna (crustacean), and Caenorhabditis elegans (nematode) revealed a relative lower toxicity of these compounds, especially when compared with Preventol® and Rocima®, commercial biocides mainly used for the conservation of cultural heritage.
The Role of Radio Observations in Studies of Infrared-Bright Galaxies: Prospects for a Next-Generation Very Large Array
Authors: Murphy Eric Joseph
Published: June 2022

The bulk of the present-day stellar mass was formed in galaxies when the universe was less than half its current age (i.e., 1≲z≲3). While this likely marks one of the most critical time periods for galaxy evolution, we currently do not have a clear picture on the radial extent and distribution of cold molecular gas and associated star formation within the disks of galaxies during this epoch. Such observations are essential to properly estimate the efficiency at which such galaxies convert their gas into stars, as well as to account for the various energetic processes that govern this efficiency. Long-wavelength (i.e., far-infrared–to–radio) observations are critical to penetrate the high-levels of extinction associated with dusty, infrared-bright galaxies that are driving the stellar mass assembly at such epochs. In this article, we discuss how the next-generation Very Large Array will take a transformative step in our understanding of galaxy formation and evolution by delivering the ability to simultaneously study the relative distributions molecular gas and star formation on sub-kpc scales unbiased by dust for large populations of typical galaxies in the early universe detected by future far-infrared space missions.

Published: June 2022

Bovine viral diarrhea virus (BVDV), also known as Pestivirus A, causes severe infection mostly in cattle, but also in pigs, sheep and goats, causing huge economical losses on agricultural farms every year. The infections are actually controlled by isolation of persistently infected animals and vaccination, but no antivirals are currently available to control the spread of BVDV on farms. BVDV binds the host cell using envelope protein E2, which has only recently been targeted in the research of a potent and efficient antiviral. In contrast, RdRp has been successfully inhibited by several classes of compounds in the last few decades. As a part of an enduring antiviral research agenda, we designed a new series of derivatives that emerged from an isosteric substitution of the main scaffold in previously reported anti-BVDV compounds. Here, the new compounds were characterized and tested, where several turned out to be potent and selectively active against BVDV. The mechanism of action was thoroughly studied using a time-of-drug-addition assay and the results were validated using docking simulations.
Exploring the Impact of TREM2 in Tumor-Associated Macrophages
Authors: Khantakova Darya , Brioschi Simone , Molgora Martina
Published: June 2022

Tumor-associated macrophages (TAMs) represent a key component of the tumor microenvironment and are generally associated with immunosuppression and poor prognosis. TREM2 is a transmembrane receptor of the immunoglobulin superfamily expressed in myeloid cells. TREM2 has been extensively studied in microglia and neurodegenerative diseases and recently emerged as a marker of pro-tumorigenic macrophages. The accumulation of TREM2-expressing TAMs was reported across numerous cancer patients and tumor models. TREM2 genetic blockade or TREM2 targeting with antibodies resulted in improved tumor control, enhanced response to anti-PD1, and significant changes in the tumor immune landscape. Preclinical studies paved the way for an ongoing clinical trial with a TREM2 depleting antibody and inspired further exploration of TREM2 targeting therapies. Here, we review the current knowledge about the impact of TREM2 in cancer, with an emphasis on the TREM2+ macrophage signature across different cancer types, the contribution of TREM2 to TAM phenotype and function, and the promising effects of TREM2 modulation.

Published: June 2022

Myxomatous mitral valve disease (MMVD) is the most common heart disease in small breed dogs. Dogs with MMVD commonly show clinical signs of dyspnea due to cardiogenic pulmonary edema (CPE). Reticulocytosis in the absence of anemia (RAA) is a hematological finding in hypoxic conditions. We aimed to assess the prevalence of RAA in dogs with CPE due to MMVD, and evaluate whether RAA is reversible with amelioration of dyspnea. Twenty-nine client-owned dogs with CPE due to MMVD were included. Dogs who died within 6 weeks of the onset of CPE were included in the non-survival group, while the others comprised the survival group. Of the 21 dogs, RAA was observed in 17 dogs (80.9%). In the RAA group, the absolute reticulocyte count significantly decreased as CPE resolved (p < 0.001). The mean absolute reticulocyte count in the RAA group was 163.90 ± 50.77 on the first measurement and 78.84 ± 25.64 after resolution of CPE. In the RAA group, no significant differences in mean absolute reticulocyte count were observed between the survival and non-survival groups at either the first or second measurement. Our results indicate that RAA occurs in dogs with MMVD-related CPE and can resolve after resolution of CPE.

Authors: He Zhenyu , Kang Bo , Tao Yuezan , Qin Li
Published: June 2022

During dry seasons or years, the runoff processes from small rivers influence the safety of riverside groundwater source fields. Water source exploitation has a considerable effect on river runoff. In this study, the riverside source field of the Liuan River in the Linquan County, Anhui Province, was analyzed. The effect of mining on the ecological flow of the river under river runoff conditions in different typical dry years was quantified. This was undertaken using numerical simulations of the groundwater flow to provide guidance for the establishment of mining schemes for riverside source fields. In 95% of typical dry years, the water supply of small rivers is insufficient. The improved 7Q10 method used to calculate the ecological flow in different dry years revealed that mining water had little effect on the ecological flow. However, during the pumping process, the groundwater level of the water source area decreased greatly. The establishment of riverside source fields can aid in reducing excessive development and use of deep groundwater. The planning, construction, and implementation of the “Divert water from the Yangtze River to the Huaihe River” project can effectively reduce the economic losses that have occurred due to severe drought in the local area.

This article examines the role of social policy at the enterprise and the degree of its importance for the organization and its employees. Staff is one of the components of the enterprise’s internal environment. Therefore, the organization needs a mechanism that contributes to increasing the employees’ motivation for high-quality performance. The internal social policy at the enterprise is an integral part of the employees’ motivation to increased efficiency. Social policy should meet the workers’ needs and interests. Social policy is formed based on the employees’ requests. Social programs at the Magnitogorsk Iron and Steel Works (MMK) are diverse and meet the interests of various groups of employees. These programs include: therapeutic and preventive programs, vouchers to resort houses and vacation retreats, preferential vouchers to camps for employees’ children, formation of healthy lifestyle principles, organization of hot meals for employees, organization of cultural recreation for employees, housing, youth, and educational programs, programs to stimulate natality and support motherhood and large families. Thanks to the educational programs, MMK improves the employees’ knowledge, skills and abilities, which allows producing better products. Also, such social policy allows attracting more qualified workers, which makes the organization competitive in the economic market. The MMK social policy is constantly improved, which contributes to an annual increase in the percentage of the employees’ satisfaction with the social policy. Thus, the MMK internal social policy has been developed based on the employees’ interests and is aimed at meeting the employees’ needs, which, in turn, helps motivate the staff to perform their work and their duties efficiently.

As in the previous year, the social and labor situation in the country and conflict potential in the labor sphere continued to take shape under the influence of the specifics of the COVID-19 pandemic and the unstable global and domestic economic situation. Under these conditions, the key factors determining the formation of the social and labor situation in the country showed multidirectional dynamics: the labor force remained stable at 75.4 million people and was supported by the delayed effect of the pension reform and labor migration, against the backdrop of the ongoing demographic decline; the number of officially registered unemployed was steadily declining and the situation on the labor market returned to pre-pandemic indicators (the unemployment rate reached 4.4% and became lower than in 2019; the maximum unemployment rate during the pandemic was noted in August 2020 at 6.4%, when about 3.5 million citizens were registered as unemployed); the number of employees laid off from Russian enterprises (institutions) consistently exceeded the number of employees hired throughout the year, therefore, the number of full-time employees at enterprises continued to go down and reached the level of 32.3 million people (1.6 million people during the year); against the backdrop of a gradual recovery of the economy, the number of part-time workers decreased and by the end of the year stabilized at 4.3 million people; the number of registered self-employed workers more than doubled, and those working on the secondary employment basis and under independent contractor agreements increased to 1.5 million people; the total wages arrears to employees of Russian enterprises (institutions) steadily decreased and in the fourth quarter reached an annual minimum of 1.257 billion rubles (-27% during the year).

In Russian psychology, the old age period has been understudied compared to the first third of a person's life. Social protection of senior citizens is carried out by the state in the form of pension provision and social services. One of the essential functions of residential care facilities is creating conditions that ensure the satisfaction of residents’ comprehensive needs, as well as maintaining the possible level of social activity. Undoubtedly, level of life satisfaction of an elderly person is largely related to the living conditions, but is not limited to them. Our preliminary studies have shown that elderly people staying in the same hospital, that is, in similar living conditions, significantly differ in the level of life satisfaction. The problem of life satisfaction among the elderly residents of the residential care facility arises due to the presence of a variety of social, medical, social and psychological problems.

Published: June 2022

The trend moment method is a forecasting method for producing an estimated number of future bread supplies so that there is no excess or shortage of bread stock in the coming month. Data on bread sales is used in this study every month from January to December 2021. Each month's sales records are useful for determining whether sales have increased or decreased. The study's findings include the development of a computerized system that can generate approximate numbers in predicting deals for the following month utilizing the PHP and MySQL programming dialects, making it simpler to determine how much bread will be sold while taking into account the stock of goods and how much will be produced in the coming months. the following month with the goal that there is no lack or abundance of bread stock. The results of sales predictions for 12 months in 2021, produce predictions in January 2022, in the 13th period with MAD (Mean Absolute Deviation) results of 40.08% and MSE (Mean Squared Error) rates of 27.64%.

Сьогодні у всьому світі зростає інтерес до розуміння цінності освіти, науки як чинника добробуту суспільства, його конкурентоспроможності на світовому ринку. Місце і роль будь-якої держави у світовому співтоваристві в існуючих умовах економіки, перш за все, пов'язані із її здатністю виробляти, споживати та застосовувати нові знання і технології. Ці процеси безпосередньо залежать від чотирьох складових: науки, освіти, виробництва та бізнесу, загальним інструментом для яких є й комунікаційні технології [1]. Безперечно, нові знання, які генеруються наукою, підготовка високоякісного людського капіталу на базі якісної освіти побудовано на знаннях. Фахівцям нового покоління належить вирішувати складні науково-технічні й економічні проблеми, вимагаючи принципово нових якостей – динамічності, компетентності, професійності, що дозволить аналізувати різноманітні завдання у найкоротші терміни та приймати оптимальні рішення.

EXTRAJUDICIAL INSTITUTIONS IN THE SPHERE OF HUMAN RIGHTS PROTECTION IN THE EU
Authors: Melnyk O.
Published: June 2022

In general, there are judicial and extrajudicial ways to protect human rights in the EU. Judicial protection of human rights from violations by international institutions falls within the jurisdiction of the Court of Justice. Extrajudicial institutions that protect the rights of the individual include the following: the Ombudsman of the European Union, the EU Agency for Fundamental Rights, and EU bodies such as the European Commission and the Council of the EU. It should be noted that the functions of these bodies in the field of individual rights are to protect the rights of the individual from violations by the bodies of the European Union and not the EU Member States. Extrajudicial bodies responsible for the protection of individual rights should be distinguished as follows. Depending on the purpose of education: specialized institutions for the protection of individual rights: the Agency for Fundamental Rights of the European Union, the Ombudsman of the European Union, and bodies of general competence: the European Commission or the Council of the EU. According to the subject of the appeal to the Institute for Protection of Rights: the Ombudsman of the European Union, for appeals of individuals, the Agency for Fundamental Rights of the European Union, which provides for appeals of certain bodies of the European Union and the Council of the EU. The Council of the European Union is the main body of the EU in terms of performing various functions. It is considered the main rule-making body of the EU. It is important to note that the issue of protection of individual rights is not a priority, but only one of the functions of this EU body. The main executive body of the EU is the Commission of the European Union, which performs the function of investigating illegal actions and can impose penalties on violators. The object of illegal actions may be an offense by a Member State of the requirements imposed on it by the EU's founding treaties, including human rights offenses. The basis in this process, within the framework of the investigation, is the right of both natural and legal persons to apply to the Commission for illegal actions committed by a Member State. The human rights procedures used by the Commission should be considered quite effective, as they combine both information and representation. Since the entry into force of the Maastricht Treaty, the EU has established a mechanism for the protection of human rights, namely the Ombudsman of the European Union.

On a considéré les particularités d'utilisation de l'analyse systémique pour caractériser les consommateurs électriques sur l'exemple de l'enseignement du cours « Consommateurs d'énergie électrique ». L'attention est attirée sur les différences dans la définition des notions de « récepteur d'énergie électrique » et de « consommateur d'énergie électrique ». On a envisagé deux approches possibles d'étude de la composition du système « Consommateur d'énergie électrique » – du simple au complexe et du complexe au simple. Les approches de la classification des consommateurs électriques sont envisagées. Les définitions des concepts paramètres et caractéristiques du récepteur de puissance sont données. Les principaux paramètres nominaux et leurs relations avec le mode de fonctionnement sont considérés. On a proposé un modèle structurel du système « Fourniture d’électricité aux récepteurs » et une approche pour considérer les caractéristiques du récepteur électrique et sa relation avec la source d'énergie électrique.
