Authors: Yan Yiming , Lin Xi , He Fang , Wang David Z. W. 
Published: August 2024

This paper investigates the operation of a novel electric vehicles (EVs) charging service mode, that is, crowdsourced mobile charging service for EVs, whereby a crowdsourcing platform is established to arrange suppliers (crowdsourced chargers) to deliver charging service to customers’ electric vehicles (parked EVs) at low-battery levels. From the platform operator’s perspective, we aim to determine the optimal operation strategies for mobile charging crowdsourcing platforms to achieve specific objectives. A mathematical modeling framework is developed to capture the interactions among supply, demand, and service operations in the crowdsourced mobile charging market. To design an efficient solution method to solve the formulated model, we first analyze the model properties by rigorously proving that a crucial variable set for operating the mobile charging crowdsourcing system includes charging price, commission control, and period-specific aggregate demand control. Besides, we provide both an equivalent condition and a necessary condition for checking the feasibility of these crucial variables. On top of this, we construct a search tree according to the operation periods in a day to solve the optimal operation strategies, wherein a nondominated principle is adopted as an accelerating technique in the searching process. The solution obtained from the proposed solution algorithm is proved to be sufficiently close to the actual global optimal solutions of the formulated model up to the resolution of the discretization scheme adopted. Numerical examples provide evidence verifying the model’s validity and the solution method’s efficiency. Overall, the research outcome of this work can offer service operators structured and valuable guidelines for operating mobile charging crowdsourcing platforms.

Universal strategy study of applying passive metasurfaces to an intra-DC wireless-optical interconnection

Published: August 2024

Free-space optical (FSO) communication can reduce the routing complexity of data center networks (DCNs), not only ensuring high-capacity optical switching, but also owning similar flexibility to the wireless connectivity. Presently, mainstream wireless-optical switching units (WOSUs) have adopted serial beam control for unicasting. As a two-dimensional planar structure composed of meta-atoms with special electromagnetic properties arranged in a certain way, a passive metasurface (PMF) has strong parallel beam regulating capability. In this paper, we propose a wireless-optical intra-DC interconnection scheme based on PMFs. Through a real PMF chip, by adjusting the polarization of an incident beam, the power distribution between normal and abnormal reflected beams can be controlled. When both reflected beams are assigned with power, we obtain a pair of beams reflected in parallel, thus simultaneously communicating with two racks. In fact, we can perform 1-to-N (N≥2) multicast by using cascaded PMFs, and 1-to-N means that each source rack can communicate with N destination racks, i.e., a wide communication coverage range. However, the cascaded PMFs may result in huge chip costs and high accumulated power loss. In this paper, we only demonstrate the 1-to-2 communication ability of our PMFs, so the communication coverage may be still limited. Hence, by introducing electrostatic drive to control the PMF rotation, each source rack can achieve a wider communication coverage range than before. As a result, all racks within the coverage range have the ability to establish communication links with the source rack. To this end, we also design a neural network to mimic the PMF rotation, further improving the communication capability between racks. We then propose a DCN-topology reconfiguration algorithm supporting the coexistence of unicasting and multicasting, in order to make real-time decisions on the matching between FSO ports with minimized latency. Finally, we established a proof-of-concept prototype system to demonstrate the parallel beam control of our PMF. The test results show that the angle error is less than 0.1°, satisfying the accuracy requirements of WOSUs, and our PMF always has a good polarization response with the insertion loss of less than 2 dB under various azimuth angles or rotation planes.
Neutrophil-percentage-to-albumin ratio is associated with chronic kidney disease: Evidence from NHANES 2009–2018
Authors: Li Jinxi , Xiang Ting , Chen Xinyun , Fu Ping 
Published: August 2024

Introduction
The neutrophil-percentage-to-albumin ratio (NPAR), a novel inflammatory biomarker, has been used to predict the prognosis of patients with cancer and cardiovascular disease. However, the relationship between NPAR and chronic kidney disease (CKD) remains unknown. The purpose of this study was to investigate the possible association between NPAR and CKD.

Methods
The cross-sectional study included participants with complete information on NPAR, serum creatinine (Scr), or urinary albumin-to-creatinine ratio (UACR) from the 2009–2018 National Health and Nutrition Examination Survey (NHANES). CKD was defined as the presence of either low estimated glomerular filtration rate (eGFR) or albuminuria. Univariate and multivariate logistic regression and restricted cubic spline regression were used to assess the linear and nonlinear associations between NPAR and renal function. Subgroup and interactive analyses were performed to explore potential interactive effects of covariates. Missing values were imputed using random forest.

Results
A total of 25,236 participants were enrolled in the study, of whom 4518 (17.9%) were diagnosed with CKD. After adjustment for covariates, the odds ratios (ORs) for prevalent CKD were 1.19 (95% CI = 1.07–1.31, p <0.05) for the Q2 group, 1.53 (95% CI = 1.39–1.69, p < 0.001) for the Q3 group, and 2.78 (95% CI = 2.53–3.05, p < 0.001) for the Q4 group. There was a significant interaction between age and diabetes mellitus on the association between NPAR and CKD (both p for interaction < 0.05). And there was a non-linear association between NPAR levels and CKD in the whole population (p for non-linear < 0.001). All sensitivity analyses supported the positive association between NPAR and CKD.

Conclusions
NPAR was positively correlated with increased risk of CKD. The NPAR may serve as an available and cost-effective tool for identifying and intervening the individuals at risk of CKD.
Scientific misconduct responsibility attribution: An empirical study on byline position and team identity in Chinese medical papers
Authors: Peng Xiaoting , Hu Dehua , Guo Yi , Jiang Hao , Wu Xunsheng , Hu Qingyuan 
Published: August 2024

Objective
The primary objective of this inquiry was to explore the nexus between authorship attribution in medical literature and accountability for scientific impropriety while assessing the influence of authorial multiplicity on the severity of sanctions imposed.

Methods
Probit regression models were employed to scrutinize the impact of authorship on assuming accountability for scientific misconduct, and unordered multinomial logistic regression models were used to examine the influence of authorship and the number of bylines on the severity of punitive measures.

Results
First authors and corresponding authors were significantly more likely to be liable for scientific misconduct than other authors and were more likely to be penalized particularly severely. Furthermore, a negative correlation was observed between the number of authors’ affiliations and the severity of punitive measures.

Conclusion
Authorship exerts a pronounced influence on the attribution of accountability in scientific research misconduct, particularly evident in the heightened risk of severe penalties confronting first and corresponding authors owing to their principal roles. Hence, scientific research institutions and journals must delineate authorship specifications meticulously, ascertain authors’ contributions judiciously, bolster initiatives aimed at fostering scientific research integrity, and uphold an environment conducive for robust scientific inquiry.
A Qualitative Meta-Analysis of Kahoot! in Language Instruction
Authors: Sağlamel Hasan , Yıldırım Mehmet Akif 
Published: August 2024

Mobile- and computer-based applications have become more prominent and popular since the COVID-19 pandemic. Digital tools have been used by teachers and students worldwide for educational purposes and in language classrooms. One such application is Kahoot!, which is an in-classroom or online testing and practice application released in 2013 and widely used in a variety of classrooms for entertaining practice for students, and a way for teachers to test students’ gains. Even though Kahoot! is extensively used and researched in language teaching/learning contexts, a meta-analysis of studies with particular focus on qualitative findings has been out of radar. This proposal addresses this gap by offering an in-depth meta-analysis of qualitative studies and findings investigating the application. Research articles utilizing qualitative methods published between 2013, Kahoot!'s official beta release, and 2022 were gathered and analyzed to reveal trends, limitations, and gaps in the literature. The findings revealed that the majority of students and teachers who participated in Kahoot! quizzes reported positive sentiments, though several concerns were raised regarding their effective use. This analysis suggests that improving instructional effects in educational settings hinges upon well-informed decision-making processes, skilful classroom management, and proficient computer literacy. When strategically employed, these factors can significantly enrich educational practices.

AbstractThe objective of the present investigation was to compare the coronary angiography results in diabetic patients with and without end‐stage kidney disease (ESKD). We included prolonged diabetic patients with ESKD (93 patients) and without ESKD (control group, 126 patients). Angiography of the coronary arteries was performed on all patients. Our results revealed that the ESKD patients tended to have a higher degree of coronary artery stenosis in all parts of LAD (p = 0.001, 0.024, and 0.005), proximal and distal RCA (p = 0.013, and 0.008), and proximal and distal LCX artery (p = 0.001, 0.008) than non‐ESKD patients. Furthermore, we found that the ESKD group had higher significant coronary artery stenosis in the LAD artery (60.5% vs. 39.5%, p < 0.001), RCA (60.3% vs. 39.7%, p < 0.001), LCX artery (79.5% vs. 20.5%, p < 0.001), and LMCA (84.6% vs 15.4%, p = 0.002) compared to control group. There was a greater prevalence of multiple vessels coronary artery disease (≥ two) among ESKD patients (29%), compared with the non‐ESKD group (16.8%, p < 0.001). Significant coronary artery stenosis was meaningfully higher in asymptomatic diabetic ESKD patients on hemodialysis than non‐ESKD diabetic patients. Coronary angiography may be beneficial in diabetic patients with ESKD regardless of whether they have ischemic symptoms with low complication rate through radial access.

Climate change impacts on the distribution of Dryomys laniger (woolly dormouse) in Türkiye: a data-driven approach
Authors: Helvacı Zeycan 
Published: August 2024

Abstract
This study examines the population structure, ecological niche, and vulnerability to climate change of the woolly dormouse Dryomys laniger in Türkiye. Integrating genetic data with species distribution modeling, the research predicts suitable habitats for D. laniger under current and future climate change scenarios until the year 2100. Using an ensemble of two machine learning models, this study finds that by 2040, the range of D. laniger will be reduced significantly, particularly in southern populations. Eastern areas emerge as a potential refuge, showing slight expansion and colonization. The low genetic diversity in this eastern population indicates the need for long-term adaptability of D. laniger. Due to the unique adaptive potential of each population, this research highlights the importance of region-specific management plans to ensure the long-term survival of this species, which appears to be vulnerable to habitat fragmentation.

Zusammenfassung
Zur Untersuchung der dynamischen Beanspruchung von ganzheitlich bionischen Leichtbauverzahnungen wird ein In-Prozess-Messsystem mit Dehnungsmessstreifen (DMS) verwendet. Diese werden auf Leichtbaustrukturen im Radkörper montiert, wo eine hohe Sensitivität erwartet wird. Die plausiblen und reproduzierbaren experimentellen Ergebnisse belegen, dass sich mit diesem Messansatz die dynamischen Beanspruchungen während der Rotation des in Eingriff befindlichen Zahnrads auflösen und vergleichend bewerten lassen.

Instances of bias: the gendered semantics of generic masculines in German revealed by instance vectors
Authors: Schmitz Dominic 
Published: August 2024

Abstract
While research using behavioural methods has repeatedly shown that generic masculines in German come with a male bias, computational methods only entered this area of research very recently. The present paper shows that some assumptions made by these recent computational studies – treating genericity as an inflectional function and computing a vector for generic usage strongly correlated with the grammatical masculine – are not without issue, and offers the use of semantic instance vectors as a possible solution to these issues. Beyond this methodological improvement, the present paper finds that generic masculines are indeed semantically more similar to specific masculines than to specific feminines – results that are in line with findings by the recent computational studies and the majority of previous behavioural studies.

Published: August 2024

Сняты 13С-ЯМР-спектры и определен элементный состав липидов серых лесных почв(Greyic Phaeozems), дисперсно-карбонатных черноземов (Haplic Chernozem Hypocalcic) и каштановых почв(Kastanazems) Западного Забайкалья. Рассчитан вклад углерода, содержащегося в липидах, в общие запасы органического углерода. Впервые представлена характеристика липидной фракции органического вещества холодных почв Западного Забайкалья. Дан анализ спектров, включающий отнесение сигналов этоксигрупп, фенольных производных и алкеновых фрагментов, а также указан диапазон химических сдвигов, характерных для определенных типов ядер углерода. Выполнено сравнение содержания различных типов структурных элементов в исследованных липидах. Показано, что основная часть липидов состоит из эфиров и жирных кислот. Анализ состава липидов выявил, что содержание атомов углерода составляет 65–73 %, а водорода – 8–10 %. Высокая концентрация атомов кислорода в липидах указывает на то, что функциональные группы, содержащие кислород, сосредоточены в алифатической части липидов. Доля углерода липидов в общем запасе органического углерода составляет6,5 % для каштановых почв,5,8 % – для серых лесных почв, 4,1 % – для дисперсно-карбонатных черноземов.
The13C-NMR spectra and elemental composition of lipids of gray forest soils (Greyic Phaeozems), dispersed carbonate chernozems (Haplic Chernozem Hypocalcic) and chestnut soils (Kastanazems) of Western Transbaikalia were determined. The contribution of carbon contained in lipids to the total reserves of organic carbon is calculated. For the first time, the work presents the characteristics of the lipid fraction of organic matter in cold soils of Western Transbaikalia. An analysis of the spectra was carried out, including the assignment of signals from ethoxy groups, phenol derivatives and alkene fragments, as well as an indication of the ranges of chemical shifts characteristic of certain types of carbon nuclei. A comparison was made of the content of various types of structural elements in the studied lipids. The results obtained showed that the main part of lipids consists of esters and fatty acids. Carbon atoms in the molecular structure of lipids are predominantly represented by aliphatic chains. Analysis of the composition of lipids showed that the content of carbon atoms is 65–73 %, and hydrogen –8–10 %. The high concentration of oxygen atoms in lipids indicates that functional groups containing oxygen are concentrated in the aliphatic part of the lipids. The share of lipid carbon in the total reserve of organic carbon is 6.5 % for chestnut soils, 5.8 % for gray forest soils, 4.1 % for dispersed carbonate chernozems.

Published: August 2024

Composite solid electrolytes based on an organic ionic plastic crystal (n-C4H9)4NBF4 with highly dispersed SiO2 with specific surface area of Ss = 324±10 m2/g have been studied for the first time. By methods of X-ray diffraction and differential scanning calorimetry, it was found that the introduction of SiO2 leads to amorphization of the salt. An unusual size effect was observed in the composites: the temperature of the polymorphic transition of the salt shifted from 67 °C to 60 °C, while the melting point did not change. The 0.15(n-C4H9)4NBF4–0.85SiO2 composite was found to possess the highest electrical conductivity (σ = 2∙10–5 S/cm at 150 °C), which is 1.5 orders of magnitude higher than that of the initial salt. Modelling of the concentration dependences of the electrical conductivity of composites using the mixing equation showed that the reason for the increase in electrical conductivity is the formation of an amorphous layer of salt, the electrical conductivity of which is 3 orders of magnitude higher than that of the crystalline phase (n-C4H9)4NBF4. The obtained results can be used for the design of high-performance composites based on organic ionic plastic crystals for application in electrochemical devices.
