Purpose. The purpose of this study was to determine the interaction between service exercise and gender on field tennis service skills.
Materials and Methods. The population in this study were Faculty of Sports, Universitas Sebelas Maret students, totaling 85 male students and 27 female students. The sample used was 24 male students and 24 female students. Collecting data on tennis serve skills using the Hewitt Tennis Achievement Test. The skill of serving tennis in court tennis is the accuracy and constancy of a tennis player's serve to start the game and being able to be skilled in serving tennis. The number of hits/ball contact with the racket is 10 hits with the target. To test the statistical hypothesis, the Tukey test was used at a significance level of α = 0,05 using SPSS 25.
Results. The results of data analysis showed that at α = 0.05 a maximum value of 0.000 < α 0.05 was obtained , for service training a maximum average value of 28.79 was obtained and an average minimum value was obtained 27.54 while gender obtained an average maximum value of 32.04 and an average minimum value of 23.79 so that a decision could be made that reject H0 and accept H1.
Conclusions. So it can be concluded that there is an interaction between service training and gender on the service skills. The form of interaction shown by the results of this calculation provides a clear reason that the diversity of student characteristics will have an impact on the difference in service training, in this case a service training should pay attention to aspects of physical ability in this case gender in the implementation of training, so between service training and gender will influence each other and interact positively in the training process, especially in achieving the results of service skills which is good.

AbstractBackground & ObjectivesThe degree of liver injury in indeterminate chronic hepatitis B (CHB) infection patients with Hepatitis B e antigen(HBeAg)‐negative and persistently normal alanine aminotransferase (PNALT) levels is yet unclear. Therefore, we aimed to assess liver histological changes in such patients by liver biopsy and explore possible predictors.MethodsOverall, 711 HBeAg‐negative CHB patients with PNALT levels who underwent liver biopsy from January 2017 to June 2022 were included in this retrospective study. The relationships between histological changes and predictors were assessed by smooth curve fitting and multivariate logistic regression analysis models. Data were also analyzed using American Association for the Study of Liver Disease (AASLD) modified alanine aminotransferase (ALT) criteria.ResultsThe proportion of significant histological changes in the indeterminate phase was higher than that in the inactive phase (53.97% vs. 41.33%). The adjusted odds ratios (aORs) of significant necroinflammation and histological changes for the indeterminate phase were 2.05 and 1.43, respectively, when compared with the inactive phase by multivariate logistic regression analyses. Significant histological changes in the‐phase were positively associated with age, ALT, Aspartate aminotransferase (AST), Hepatitis B surface antigen (HBsAg), and Hepatitis B virus (HBV) DNA levels but negatively correlated with platelet (PLT) levels. HBV DNA ≥5 log10 U/L and PLT <200 × 109/L were independent predictive factors for assessing histological changes in indeterminate‐phase patients. Similar analysis findings were obtained using the two sets of modified ALT criteria.ConclusionsSignificant histological changes are not rare in indeterminate‐phase CHB patients and are higher than in the inactive phase, regardless of the ALT criteria. Histological investigation is strongly suggested for intermediate stage patients with HBV DNA >5 log10 U/L or PLT <200 × 109/L and antiviral therapy should be considered for such patients.
Ecology and Biodiversity of Coral Reef Polychaetes of Guam and Saipan, Mariana Islands.
Authors: Bailey‐Brock Julie H. 
Published: October 2023

AbstractPolychaetes collected from coral reefs and other coastal habitats on Guam and Saipan, and information from published studies bring the known number of species from these two islands to 101 and 15, respectively. Sediment and rock dwelling species collected, and those previously recorded, belong to 25 families. Polychaete assemblages are compared on the basis of species richness, genera in common, and trophic categories, with other West Pacific, Hawaiian and East Indian Ocean locations. Polychaetes from Guam are similar to those on reef flats of Hawaii, Enewetak, and Indonesia in faunal composition and density. Despite the limitations in comparable collecting effort and quantitative analyses for some of the areas, these coral reefs have similar complements of families and genera present, and proportions of four trophic categories.
Periphyton Architecture and Susceptibility to Grazing by Periwinkles (Littorina littorea, Gastropoda)
Authors: Sommer Ulrich 
Published: October 2023

AbstractPeriphyton was grown on transparent plastic substrata in the Kiel Fjord and used for short‐term laboratory experiments to study the feeding selectivity of the periwinkle Littorina littorea in response to the vertical structure of the periphyton. The susceptibility of algae to periwinkle grazing was assessed by comparing the species‐specific biomass within the grazing tracks of the snails to the biomass outside the tracks. After 3 weeks of incubation, the periphyton consisted of a scattered monolayer of algal cells without vertical structure. No apparent grazing could be found. After 6 weeks of incubation, periphyton consisted of a tightly attached undergrowth (mainly Cocconeis scutellum, Bacillariophyceae, and Myrionema sp., Phaeophyceae) and canopy of filamentous (Melosira moniliformis, Bacillariophyceae) and stalked forms (Achnanthes longipes, Bacillariophyceae). The unicellular diatoms Fragilaria tabulata and Stauroneis constricta grew partly on the primary substratum and partly as epiphytes on the canopy species. The canopy species and the epiphytes were decimated inside the grazing tracks, while the tightly attached undergrowth species appeared ungrazed.
Basin‐Wide Considerations for Water Quality Management: Importance of Phosphorus Retention by Reservoirs
Authors: Kennedy Robert H. 
Published: October 2023

AbstractThe relationship between phosphorus retention (RP) and water residence time (RT) was assessed for selected U.S. Army Corps of Engineers reservoirs and found to be influenced by areal phosphorus loading rate (PL). For reservoirs with high PL (>15 gm/m2/yr), RP increased markedly with modest increases in RT. Reservoirs with lower values of PL exhibited less dramatic responses in RP to changes in RT. The water quality management implications of this are great since reservoirs for which marked changes in RP can occur with modest changes in RT are potential management loci within a drainage basin.

Published: October 2023

AbstractThe metabolic syndrome (MetS) and Alzheimer's disease share several pathological features, including insulin resistance, abnormal protein processing, mitochondrial dysfunction and elevated inflammation and oxidative stress. The MetS constitutes elevated fasting glucose, obesity, dyslipidaemia and hypertension and increases the risk of developing Alzheimer's disease, but the precise mechanism remains elusive. Insulin resistance, which develops from a diet rich in sugars and saturated fatty acids, such as palmitate, is shared by the MetS and Alzheimer's disease. Extracellular vesicles (EVs) are also a point of convergence, with altered dynamics in both the MetS and Alzheimer's disease. However, the role of palmitate‐ and glucose‐induced insulin resistance in the brain and its potential link through EVs to Alzheimer's disease is unknown. We demonstrate that palmitate and high glucose induce insulin resistance and amyloid precursor protein phosphorylation in primary rat embryonic cortical neurons and human cortical stem cells. Palmitate also triggers insulin resistance in oligodendrocytes, the supportive glia of the brain. Palmitate and glucose enhance amyloid precursor protein secretion from cortical neurons via EVs, which induce tau phosphorylation when added to naïve neurons. Additionally, EVs from palmitate‐treated oligodendrocytes enhance insulin resistance in recipient neurons. Overall, our findings suggest a novel theory underlying the increased risk of Alzheimer's disease in MetS mediated by EVs, which spread Alzheimer's pathology and insulin resistance.
Theory development in a globalized world: Bridging “Doing as the Romans Do” with “Understanding Why the Romans Do It”
Authors: Homer Stephen Thomas , Lim Weng Marc 
Published: October 2023

AbstractThe dialectic between micro and macro theoretical perspectives remains a cornerstone in the study of business and social science. As globalization intensifies, these perspectives offer unique but sometimes conflicting views, with macro theories providing panoramic insights and micro theories zooming into nuanced contexts. The dominance of Western‐centric etic theories, though beneficial historically, faces challenges in the evolving tapestry of our interconnected world. Firms today grapple with intricate landscapes influenced by varied cultural, political, and social factors, necessitating more context‐sensitive tools. This article delves into the merits and limitations of both perspectives, advocating for the symbiotic use of micro and macro theories to navigate the complexities of today's globalized business environment. By nurturing both theoretical paradigms, we pave the way for a richer, more holistic understanding of modern‐day challenges and opportunities.
Quantitative analysis of the glutathione pathway cellular metabolites by targeted liquid chromatography‐tandem mass spectrometry
Authors: Serafimov Kristian , Aydin Yüsra , Lämmerhofer Michael 
Published: October 2023

Glutathione, its biosynthesis intermediates, and other thiol metabolites are of central relevance for the redox homeostasis of cells. Their analysis is critical due to the facile interconversion of redox pairs during sampling, sample preparation, and data acquisition, in particular in the electrospray ionization interface. In this work, we propose a fast‐targeted liquid chromatography‐tandem mass spectrometry method to accurately analyze 14 metabolites from the glutathione pathway. N‐Ethylmaleimide reagent is added with the extraction solvent and instantly stabilizes the thiol‐redox state by derivatization. Liquid chromatographic separation of the analytes was performed on a sub‐2 μm superficially porous hydrophilic interaction liquid chromatography column with sulfobetaine chemistry. Tandem mass spectrometry with triple‐quadrupole mass spectrometry in multiple‐reaction monitoring acquisition mode allowed sensitive detection of the targeted metabolites with limits of quantification in the range of 5–25 nM. Run times of 3 min enable a high throughput analysis of cellular samples. For calibration, a 13C‐labelled cell extract was used as an internal standard. The method was validated and the concentrations of glutathione and its biosynthesis intermediates were determined in HeLa cells.

AbstractThe pretreatment quality of intimate relationships can promote or interfere with couple therapy for posttraumatic stress disorder (PTSD) treatment response. We tested whether baseline relationship satisfaction predicted clinical and process outcomes in two dyadic treatments for PTSD. Using data from a randomized trial comparing brief cognitive behavioral conjoint therapy (bCBCT) for PTSD to PTSD family education (PFE) among 137 military veterans and their partners (N = 274, Mage = 42.3 years, 46.7% White, 81.0% male veteran partner), we examined whether baseline relationship satisfaction (Couples Satisfaction Index; CSI‐32) predicted change in PTSD symptom severity (Clinician Administered PTSD Scale for DSM‐5; CAPS‐5), psychosocial functioning (Brief Inventory of Psychosocial Functioning; B‐IPF), and relationship satisfaction at posttreatment and 6‐month follow‐up. We also explored associations with process outcomes (working alliance, treatment satisfaction, dropout). In both treatment conditions, neither partner's baseline CSI‐32 score moderated change in veteran CAPS‐5 or B‐IPF score or any process variable. However, baseline CSI‐32 scores moderated both partners’ CSI‐32 score change during bCBCT and PFE; participants who scored in the distressed range at baseline (n = 123) experienced significant improvements in relationship satisfaction, β = .199, whereas there was no change among those in the nondistressed range at baseline (n = 151), β = .025. Results suggest bCBCT and PFE are effective in improving PTSD symptoms and psychosocial functioning regardless of whether a couple is experiencing clinically significant relationship distress; further, these treatments improve relationship satisfaction for the most distressed individuals.

Published: October 2023

AbstractTo further enhance the fatigue resistance of spiropyran‐based photochromic materials and to explore the functionality of organic–inorganic metal oxide microcapsule shell materials, cross‐linked (P(MMA‐PETA)) and homopolymer (PMMA) shells have been developed by cross‐linking TiO2 and hybridizing ZnO on a PMMA matrix. PMMA/TiO2 photochromic microcapsules and PMMA/ZnO photochromic microcapsules with ultraviolet (UV)‐absorbing function are prepared by successfully encapsulating spiropyran photochromic compounds using these two composite shells. The results show that both microcapsules exhibit a complete spherical core–shell structure with good UV resistance and thermal stability. The TG test underlines a 50% coating rate of PMMA/ZnO microcapsules on spiropyran photochromic material, with an optimal ZnO addition of 10% and particle size range from 2 to 8 µm, effectively blocking UV‐A and part UV‐B radiation. Further, a 75% maximal coating rate is observed for PMMA/TiO2 microcapsules on spiropyran with optimal TiO2 addition at 2–4%, a particle size of around 5 µm, diffusely reflecting 48% of UV rays. The photochromic fabrics prepared with PMMA/TiO2 microcapsules have better UV resistance, with a UV protection factor value of 59.48, and excellent fatigue resistance after at least 30 cycles of UV–visible light irradiation.

Published: October 2023

AbstractIn this work, a commercially available styrene‐butadiene block copolymer is functionalized with vinyl benzyl chloride (VBC) via solution free‐radical polymerization to obtain g‐VBC‐x graft copolymers. The molar content of VBC, also named functionalization degree (FD) or x, of g‐VBC‐x is varied in the range 10–27 mol%, simply by varying the concentration of VBC monomer in the feed or the reaction time. The g‐VBC‐x copolymers are used to prepare films by solution casting that are converted into anionic exchange membranes (AEMs) by heterogeneous quaternization reaction with trimethylamine (TMA). The membranes are extensively characterized to assess their thermal, mechanical, and ex‐situ electrochemical properties. The best performing AEMs having an FD of 20% and 27% are tested in an AEM single‐cell electrolyzer. Both of them are found to retain their original conductivity after more than 40 and 100 days, respectively. In particular, the membrane with the higher FD is characterized by the best in‐situ performance both in terms of ionic conductivity and cell potential.

AbstractFlexible humidity sensors have received more and more attention in people's lives, and the problems of gas permeability and power supply issues of the device have long been areas in need of improvement. In this work, inspired by the high air permeability of daily wear clothing and galvanic batteries, a self‐powered humidity sensor with high air permeability and fast response is designed. A nylon fabric/GO net (as a humidity sensitive layer and solid electrolyte) is obtained by spraying technique. This structure enables the sensor to have fast response/recovery (0.78 s/0.93 s, calculated at 90% of the final value), ultra‐high response (0.83 V) and excellent stability (over 150 cycles) at 35 °C. Such sensors are useful for health monitoring, such as non‐contact monitoring of human respiratory rate before and after exercise, and monitoring a level of humidity in the palms, arms, and fingers. This research provides an idea for developing a flexible wearable humidity sensor that is both breathable and self‐powered and can also be mass‐produced similar to wearable clothing.
Algorithm-Agnostic Feature Attributions for Clustering
Authors: Scholbeck Christian A. , Funk Henri , Casalicchio Giuseppe 
Published: October 2023

AbstractUnderstanding how assignments of instances to clusters can be attributed to the features can be vital in many applications. However, research to provide such feature attributions has been limited. Clustering algorithms with built-in explanations are scarce. Common algorithm-agnostic approaches involve dimension reduction and subsequent visualization, which transforms the original features used to cluster the data; or training a supervised learning classifier on the found cluster labels, which adds additional and intractable complexity. We present FACT (feature attributions for clustering), an algorithm-agnostic framework that preserves the integrity of the data and does not introduce additional models. As the defining characteristic of FACT, we introduce a set of work stages: sampling, intervention, reassignment, and aggregation. Furthermore, we propose two novel FACT methods: SMART (scoring metric after permutation) measures changes in cluster assignments by custom scoring functions after permuting selected features; IDEA (isolatedeffect on assignment) indicates local and global changes in cluster assignments after making uniform changes to selected features.
