Abstract

Predicting game outcomes has significantly garnered the interest of researchersin recent years. The role of player performance is integral in-game analytics, significantlyimpacting the interpretation and results of the analysis. Quantifyingfactors impacting tennis games would advance the analysis of player’s performance.The proposed work intends to use real-time data from each game pointto determine essential feature values, formulate and assess the impact of psychologicalmomentum, and employ machine learning methodology on mid-matchdata for predicting the game’s victor. The data source is from Wimbledon and US Open games from 2017 to 2022, a total of 1592 games, and utilize 363 gamesof 2023 to evaluate their forecasting ability. We first obtained weights throughinformation entropy and defined psychological momentum, and then 3 best classifiers,random forest, CatBoost, and Logistic Regression, were detected to assessthe features. Additionally, we implemented a soft voting ensemble method integratingthe Random Forest and CatBoost classifiers. All four models achieve over90% accuracy and F1-score, with the soft voting classifier performing the best(accuracy: 97.5%, F1 score: 97.4%). These models achieve predictive accuraciesabove 70% using the first 25% data of a game.

Published: July 2024

Abstract

Objective: This study examines the effects of 16 weeks of taichi exercises on single-leg balance and attentional network in a sedentary population. The effect of the attention network factor in the improved balance ability was investigated. Methods: A randomized two-group parallel controlled trial. 43 sedentary people (23 tai chi group and 20 control group) participated in this study. Each subject was required to meet the criteria of sitting and lying down for an average of at least 7 hours per day for the past 1 month, with no exercise habits. Tai chi was used as the primary exercise intervention. The training was administered three times a week for 16 weeks. The control group would be required to submit the Sedentary Behavior Questionnaire weekly and ensure similar lifestyle habits as before. We measured subjects' dual-task single-leg balance using the Tecnobody-PK252 balance apparatus before and after 16 weeks, and their attentional ability using the attention network test.
Results: Tai chi significantly improved dual-task single-leg balance and attention in the sedentary group (p < 0.05). There was a significant difference compared to the control group. A correlation was found between improved attentional ability and sway path scores. There was no significant difference in the control group before and after the experiment (p > 0.05).
Conclusion: Tai chi can improve dual-task single-leg balance in sedentary people. Tai chi can improve the attentional network ability of sedentary people. Improvements in dual-task balance in the tai chi group correlated with improvements in the attentional network with Orienting and Executive control network.
Transcriptome analysis of stinging catfish (Heteropneustes fossilis) kidney reveals its role during adaptation to hypertonic environment
Authors: Chutia Priyambada , Das Manas , Saha Nirmalendu 
Published: July 2024

Abstract

Background
The facultative air-breather stinging catfish Heteropneustes fossilis, can easily adapt to anisotonic environment up to a level of 6 ppt. The teleost kidney is an essential osmoregulatory organ and plays a vital role in immune system maintenance.
Methods and Results
We took kidney samples from control and 100 mM NaCl-treated stinging catfish to study their adaptive responses to salinity stress. We used high-throughput sequencing followed by de novo transcriptome assembly to analyze the transcriptome of the fish. A total of 89,813 unigene transcripts with 47.28% GC content and 901 bp average length were produced during the final contig assembly. A BLAST search revealed that 45,855 unigenes had a considerable amount of similarity to sequences found in the Swiss-Prot and Ref-Seq databases. Comparative transcriptome analysis revealed that 1660 genes were differentially expressed (693 were upregulated and 967 downregulated) in the kidneys of fish treated with NaCl compared to control kidneys. Several GO pathway terms, including "inflammatory response" and "neutrophil chemotaxis" in the biological process category, "cytoplasm" and "integral component of membrane" in the cellular component category, and "metal ion binding" and "DNA binding," in the molecular function category, were found to be significantly over-represented by enrichment and functional analysis of the DEGs. Additionally, there was an overrepresentation of KEGG pathways like "chemokine signaling pathway," "cytokine-cytokine receptor interaction," and "metabolic pathways."
Conclusion
The current work demonstrates that tolerance to hypertonic environmental stress necessitates the activation of many molecular pathways involved in sustaining the physiological systems in air-breathing stinging catfish.

Published: July 2024

Abstract

A connected collection of nodes in a network excluding which results in the decomposition of a network into components such that the cardinality of each component is at most equal to the cardinality of the collection is referred to as a connected safe set (CSS). A CSS of the least size is called connected safe basis and its cardinality is referred to as a connected safe number (CSN). In this article, we computed CSS and CSN of certain cycle-related networks, namely tadpole network, helm network, and prism network. In addition, we presented an application of the CSS for ensuring an optimal water distribution network in a smart city.

Authors: Hu Liang , Wu Xianwei , Che Xilong 
Published: July 2024

Abstract

In the present era, scientific computation is gradually becoming a primary research method, with an increasing number of researchers engaging in simulation studies on various high-performance computing platforms. Scientific workflows play a crucial role in organizing these complex research tasks effectively. However, poorly managed scientific workflows can lead to wastage of HPC com- putational resources. Researchers using scientific workflows for their studies hope to simplify operations and minimize additional learning costs. The parameter optimization of Earth Sys- tem Models (ESM) poses specific challenges due to its complexity, exacerbating these issues. To address these challenges, we propose a scientific workflow management framework for surrogate- based ESM parameter optimization. In this framework, various tools are deployed, and multiple management mechanisms are established to enhance control over different stages of the workflow cycle. The goal is to conserve platform resources and improve the user experience. We monitor a team engaged in tuning CAM parameters before and after adopting the framework, and the results demonstrate significant improvements in various metrics after deploying the framework. This validates that our proposed scientific workflow management framework effectively addresses the challenges in user operations and resource management during surrogate-based ESM optimization processes. It holds demonstrative significance in showcasing the potential of our framework.

Published: July 2024

Abstract

β-thalassemia(β-TH) is an inherited hemoglobin disorder marked by ineffective erythropoiesis, anemia, splenomegaly, and systemic iron overload, predominantly affecting developing countries in tropical and subtropical regions. Despite extensive research on its pathogenesis, the interactions between gut microbiota and metabolites in β-TH remain poorly understood. This study compares fecal metabolomics and metagenomics between wildtype (WT) and heterozygous Th3/+ mice, a model for non-transfusion-dependent β-thalassemia intermedia. Our results show increased intestinal bilirubin metabolism, with significant elevations in metabolites such as biliverdin, bilirubin, and stercobilin. Metagenomic analysis revealed notable differences in bacterial composition between Th3/+ and WT mice. Specifically, Cupriavidus metallidurans was identified as a key bacterium that mitigates anemia by reducing liver and spleen iron deposition. This is the first study to ameliorate anemia in mice by altering gut microbiota, presenting new strategies for β-TH management.

Published: July 2024

Abstract

Multicomponent traditional medicine prescriptions are commonly used for disease treatment in Ethiopia. However, the lack of consistency in these prescriptions across practitioners, cultures, and locations has impeded the development of reliable therapeutic medicines. Therefore, a systematic analysis of traditional medicine information is essential to identify consistent and dependable medicinal materials, fostering harmony in these practices. In this study, we compiled and analyzed a dataset comprising 505 prescriptions, encompassing 567 different medicinal materials used to treat 106 diseases. Utilizing association rule mining, we uncovered significant associations between human diseases and medicinal materials. Additionally, in silico analysis was conducted to provide support for these associations and validate traditional medicinal uses. The results of the study revealed significant associations between diseases and medicinal materials. Notably, wound healing showed a strong association with Rumex abyssinicus Jacq, prompting further molecular-level investigation to confirm this association. In silico analysis of the phytochemicals of Rumex abyssinicus Jacq identified 756 therapeutic targets enriched in various KEGG pathways and biological processes. Using the random-walk with restart algorithm in the CODA PPI network, we identified disease associated with these targets, including cancer, inflammation, congenital malformations, and diseases of metabolic, immune, respiratory, and neurological systems. Furthermore, numerous hub target genes in the PPI network were directly associated with the wound healing process, supporting the findings of the association rule mining and the traditional use of Rumex abyssinicus Jacq for treating wounds. In conclusion, this research revealed important associations between diseases and medicinal materials, emphasizing the therapeutic potential of Rumex abyssinicus Jacq. It provides a foundational understanding for further exploration of the efficacy of traditional and natural-products based medicines.

Authors: Huang Shihua , Mangi Farman Ali , Fatima Ghulam 
Published: July 2024

Abstract

A broadband double layer metamaterial circular polarizer using H-type spiral structure is proposed. The metamaterial structure consists of 784 unit cells arranged in a 28 x28 layout. Each unit cell is composed of H-spiral structure which are twisted by an angle of ± 45o. The right handed circular polarization (RHCP) and left handed circular polarization (LHCP) with high transmission circular polarization are achieved at 27.95GHz-29.95GHz, 31.04GHz-34.31GHz, 35.26GHz-35.96GHz, 38.08GHz-38.58GHz, 39.46GHz-39.60GHz, and 29.96GHz-31.03GHz, 34.32GHz-35.25GHz, 38.59GHz-39.45GHz, respectively. In addition, the broadband axial ratio bandwidth of 5.0%, 2.67%, 8.17%, 2.32%, 1.75%, 1.25%, 2.15%, and 0.35% is achieved across the 20–40 GHz range. The prototype model is fabricated and measured for the validation of simulated results. The simulated and measured results reveal that the metamaterial structure have efficient performance, in terms of Axial Ratio, broadband, transmission loss and circular dichroism for advanced polarization conversion applications. The overall calculated axial ratio bandwidth of 23.66% is extracted across the 20–40 GHz.
Characteristics and Predictors of Stillbirths at the West Gonja Catholic Hospital, Ghana: A Retrospective Analysis Using Birth Registry Data
Authors: Abesig Wadeyir Jonathan , Ganle John Kuumuori 
Published: July 2024

Abstract

Background
Predominantly, stillbirths occur in Low- and middle-income countries, with 75% of stillbirths occurring in sub-Saharan Africa and southern Asia. In Ghana, the stillbirth rate is 22/1000 births. Sadly, there is still limited understanding of the determinants of stillbirths in many parts of Africa, including the Savannah region of Ghana. This study examined the characteristics and predictors of stillbirths at the West Gonja Catholic Hospital from 1st January 2019 to 31 December 2020.
Methods
A retrospective, unmatched case-control study that compared data of mothers with stillbirths to mothers with live births at the West Gonja Catholic Hospital, was conducted. The total sample was 385 mothers (55 stillbirths and 330 live births) who delivered at the West Gonja Catholic Hospital from 1st January 2019 to 31st December 2020. The data were extracted from delivery registers in the labour ward using a Microsoft Excel data extraction form. We used logistic regression to estimate crude and adjusted odds ratios at a 95% confidence level.
Results
Completing Junior High School reduces the odds of a stillbirth (aOR 0.16 95% CI = 0.03–0.77, p < 0.022). The odds of having a stillbirth were higher among mothers who lived in rural areas (aOR 2.92, 95% CI = 1.01–7.86, P < 0.034), mothers who made < 4 antenatal visits (aOR = 6.11, 95%CI = 2.35–15.88, p < 0.01 ), mothers with hypertensive disease in pregnancy (aOR 10.56 95%CI = 2.31–48.26, p < 0.002), mothers who took < 3 doses of IPTp during pregnancy (aOR 11.26 95%CI = 4.38–28.97, p < 0.01 ), mothers who delivered preterm babies (aOR 13.14 95%CI = 3.16–54.58, p < 0.01), mothers who delivered postdate babies (aOR 9.77, 95%CI = 2.62–36.37), p < 0.01), and mothers with breech presentation of the foetus at birth (aOR 55.82, 95%CI = 8.53-365.44, p < 0.01).
Conclusion
A combination of socio-demographic, maternal and foetal factors determined stillbirth at the West Gonja Catholic Hospital between 1st January 2019 and 31st December 2020. Continuous community sensitisation on the effect of key risk factors, early classification of pregnancies into risk groupings and institution of special ANC for high-risk groups are recommended to improve on birth outcomes at the hospital. Other innovative strategies such as domiciliary antenatal care services are recommended to improve the timing and number of ANC attendance. Continuous professional development of midwives and community health nurses in the identification, management and timeous referral of high-risk pregnancies and labour are also recommended to help reduce this undesirable outcome of pregnancy.
Influence of a yogic lifestyle on COVID-19 vaccine refusal among yoga practitioners in Germany: A cross-sectional analysis
Authors: Beerenbrock Yvonne , Büssing Arndt 
Published: July 2024

Abstract

Background: The coronavirus disease 2019 (COVID-19) pandemic has tested society’s vaccine acceptance, particularly among health-conscious yoga practitioners. However, data on vaccine hesitancy in this group are limited.
Methods: To address this gap, we surveyed 1,545 yoga practitioners to assess the impact of vaccine refusal within the context of their yogic lifestyle using quantitative methods.
Results: Surprisingly, 28% of respondents refused vaccination. Age, frequency of yoga practice, and frequency of studying the philosophical background showed no significant influence on COVID-19 vaccine hesitancy. By contrast, the frequency of meditation, adherence to a strict vegetarian diet, individual importance of yoga, quality of life, and adherence to yoga ethics (yamas and niyamas) significantly influenced vaccine refusal. Sex had only a marginal effect. Practitioners who prioritized yoga as a spiritual path, adhered to strict vegetarianism, engaged in daily meditation, and maintained strong yoga ethics were more likely to refuse vaccination.
Conclusion: These findings provide insights into how a specific lifestyle may influence health behaviors, values, and decision-making processes in minority groups with specific health convictions.
Trial Registration: This study was retrospectively registered at the German Clinical Trials Register (https://www.drks.de) (DRKS00034607).

Published: July 2024

Abstract

Introduction
Encouraging childbearing is an important measure to optimise the current age structure of the population, and the core fertility support policy is fertility-friendly as well as family-friendly.
Materials and methods
This paper statistically analyses the fertility support policies of the country and provinces and cities in the past ten years to clarify the developmental changes and improvement trends of fertility support policies.
Results
Around the evolution of the policy theme, the fertility support policy shows the development trend of sprouting to shaping, unidirectional to expanding the dimension and increasing the surface, auxiliary to active, valuing birth to valuing parenting, family to socialisation, adjusting the number of births to reducing the cost of childbearing, raising and educating.
Discussion and conclusion
Further attention needs to be paid to the holistic, systemic, family and gender perspectives of the policy.

Published: July 2024

Abstract

Promoting the permeability of deep, low-permeability coal seams through biological means is currently a research hotspot for enhancing the efficiency of coalbed methane extraction. There are few reports in the literature on whether it is possible to promote the development of the microstructure of the coal matrix by the degradation and metabolism of certain groups of functional microorganisms under the stimulation of nitrogen sources. In this study, we selected anthracite coal from Sihe Mine for microbial anaerobic degradation culture experiments. The effects of adding functional microorganisms on the microstructure of anthracite coal under the stimulation of nitrogen source was analyzed by high-throughput sequencing of samples before and after the cultivation and microcharacterization experiments of coal samples. The results showed that the peak amount of residual methane desorption from the coal during the biodegradation process in the experimental group reached 0.640 mL/g coal, and the cumulative amount of methane desorption in the whole period was as high as 1.318 mL/g coal. 16S rRNA high-throughput sequencing results indicated that the bacterial community structure had undergone significant succession after the biodegradation experiments, and that the Firmicutes represented by Bacillus(82.41% of the total) occupied the dominant niche. Metabolic pathway analysis based on KEGG database showed that the degradation of aromatic compounds by microorganisms appeared to be significantly enhanced by the addition of nitrogen sources. Alaso, the relative abundance of a number of key metabolic enzyme genes capable of catalyzing the introduction of oxygen-containing functional groups into the structure of the coal molecule and the de-cyclization reaction were increased. FTIR experiments revealed that biodegradation stimulated by nitrogen source reduced the aromaticity of coal by 59.62% and enhanced the hydroxyl functional group content by 1.822 times.Mercury pressure and low-temperature nitrogen adsorption experiments showed that the micropore pore volume of the treated coal decreased by 34.09%, and the macropore pore volume accounted for an increase of 168.28%, with an average pore size increment of 60.72 nm, and the adsorption level of the gases decreased by 46.1%. Therefore, the nitrogen source can stimulate Firmicutes on the degradation of polycyclic aromatic hydrocarbon and increase the content of oxygen-containing functional groups, which might promote the development of pores in coal and make the difficult-to-desorption methane desorb rapidly.

Published: July 2024

Abstract

This research focuses on the gain measurement and modeling of optical silica-germanium glass doped by erbium and bismuth activators to implement a two-band planar optical amplification. Using two activators, bismuth active centers with germanium (BAC-Ge) expand the amplification of the near-infrared bandwidth up to 1650 nm, where the optical attenuation of telecommunication fibers is less than 0.3 dB/km. We described the amplification mechanism based on the luminescence spectral response of the activators. We determined the differential amplification gain of the fabricated active glasses using a pulse measurement method and the calculation of the authentic model using waveguide propagation equations. A single source with a wavelength of 1480 nm was used for pumping in both optical bands. The emission and absorption cross-section coefficients were determined from the luminescence spectrum of the glasses by the Füchtbauer-Ladenburg equation with a Gaussian approximation and McCumber's theory. The calculated differential gain values are in good agreement with the measurement results. Our research leads to the conclusion that BAC-Ge optical activity is conditioned by the location of Bi atoms in the germano-silicate glass matrix with high GeO2 content.

Abstract

Arbuscular mycorrhizal fungi (AMF) provide host plants with water and nutrients. Here, we investigated the response of six rice varieties from two ecotypes (three irrigated and three rainfed upland varieties) to inoculation at five fertilizer levels, under continuous flooding (CF) and alternate wetting and drying (AWD) irrigation in field conditions in two consecutive years. For both irrigated and upland rice, the application of AWD irrigation and reduction in NPK fertilizer levels resulted in significant yield losses, with a greater magnitude for irrigated rice. Under AWD irrigation, inoculation with AMF reduced relative yield losses with a more pronounced effect at half recommended dose of fertilizer. Under CF, the yield losses related to reduction in NPK fertilizer levels were often fully offset by inoculation with AMF. On the other hand, irrigation regime, fertilizer level and ecotype were identified as significant sources of variation in mycorrhizal inoculation effect for many yield-related traits including, total biomass, tiller number, panicle number, fertility and maturity dates. Our results suggest that inoculation with AMF could be associated with AWD irrigation and/or low NPK inputs to contribute to mineral fertilizer and water saving in both irrigated and upland rice production systems.
