AbstractPurposeTo evaluate clinical outcomes after endometrial receptivity analysis (ERA).MethodsThis was a multicenter, retrospective cohort study involving 861 women who underwent ERA testing at certified fertility clinics in Japan, and who received subsequent personalized blastocyst embryo transfers (ET) between 2018 and 2020. Clinical outcomes, including pregnancies, miscarriages, and live births, were evaluated according to receptivity status for ERA.ResultsMean patient age was 37.7 years (SD = 4.0), and the median number of previous ETs was 2 (interquartile range, 2–3). 41.0% (353/861) of patients were non‐receptive for ERA testing. Clinical pregnancy, miscarriage, and live birth rates for personalized blastocyst ET were 44.5% (226/508), 26.1% (59/226), and 26.8% (136/508) for receptive patients, and 43.1% (152/353), 28.3% (43/152), and 28.9% (102/353) for non‐receptive patients, all statistically nonsignificant. Multiple logistic regression demonstrated similar nonsignificant associations between receptivity and clinical outcomes. Greater patient age, smoking, and longer duration of infertility were significantly and negatively associated with receptivity, whereas a history of delivery was positively associated and statistically significant.ConclusionsClinical outcomes after ERA testing were similar between receptive and non‐receptive patients. Further prospective study including an appropriate comparison group are warranted to evaluate the efficacy of ERA testing.

AbstractPrior to the COVID‐19 pandemic, food insecurity and depression were growing public health concerns among graduate students. Yet, little is known about how COVID‐19‐related stressors exacerbated these health outcomes among graduate students. To address this research gap, this study examined two types of COVID‐19‐related stressors, anticipated concerns about remote learning and challenges interfering with academic and research responsibilities, in relation to food insecurity and depressive symptoms among public university graduate students. Between August and October 2020, 631 graduate students who utilised basic needs services from seven University of California campuses completed an online survey assessing the effects of COVID‐19 on their academic experiences, mental health, and basic needs security. Regression analyses examined associations of COVID‐19‐related concerns and COVID‐19‐related challenges with food insecurity as well as COVID‐19‐related concerns and COVID‐19‐related challenges in relation to depressive symptoms. All four models were adjusted for age, sex, race and ethnicity, campus affiliation, and living with a partner. Models examining food security status as the dependent variable were adjusted for depressive symptoms and vice versa. Graduate students concerned about delayed graduation, post‐graduate employment, isolation from faculty and not having access to healthcare reported higher counts of depressive symptoms. Challenges associated with higher counts of depressive symptoms included caring for family more than usual, spending more time on errands and not paying for utilities in full. Students concerned about accessing healthcare had higher odds of experiencing food insecurity. Challenges associated with food insecurity included spending more time on errands, being unable to afford housing and sending money to family members during the pandemic. Our findings illuminate the pandemic's deleterious consequences on graduate students' mental health and food security, underscoring the need for strong academic and basic needs programs and policies.
Does use of health behaviours to cope with stress predict sleep impairment in trauma‐exposed community adults?

Published: November 2023

AbstractIndividuals who have been exposed to trauma experience high levels of sleep impairment. Given the well‐established negative effects of stress on sleep, the ways in which trauma‐exposed individuals cope with stress is likely to be associated with their sleep. This study examined how the use of health behaviours (i.e., exercise, comfort eating, and maintaining a self‐care routine) to cope relate to sleep impairment in a community sample of trauma‐exposed adults (N = 84, mean age = 35.1, 83% female). We also tested whether use of health behaviours to cope moderates the relationship between psychological distress and sleep impairment. Results demonstrate that exercise and maintaining a self‐care routine to cope are associated with less sleep impairment, while comfort eating to cope is associated with greater sleep impairment. Further, comfort eating to cope moderated the relationship between distress and sleep impairment. Findings suggest that the use of health behaviours to cope is differentially associated with sleep impairment, which has important clinical and research implications for the health of trauma‐exposed adults.
Integrating Artificial DNAzymes with Natural Enzymes on 2D MOF Hybrid Nanozymes for Enhanced Treatment of Bacteria‐Infected Wounds

Published: November 2023

AbstractRemoval of invasive bacteria is critical for proper wound healing. This task is challenging because these bacteria can trigger intense oxidative stress and gradually develop antibiotic resistance. Here, the use of a multienzyme‐integrated nanocatalytic platform is reported for efficient bacterial clearance and mitigation of inflammatory responses, constructed by physically adsorbing natural superoxide dismutase (SOD), in situ reduction of gold nanoparticles (Au NPs), and incorporation of a DNAzyme on 2D NiCoCu metal–organic frameworks (DNAzyme/SOD/Au@NiCoCu MOFs, termed DSAM), which can adapt to infected wounds. O2 and H2O2 replenishment is achieved and alleviated the hypoxic microenvironment using the antioxidant properties of SOD. The H2O2 produced during the reaction is decomposed by peroxidase (POD)‐like activity enhanced by Au NPs and DNAzyme, releasing highly toxic hydroxyl radicals (•OH) to kill the bacteria. In addition, it possesses glutathione peroxidase (GPx)‐like activity, which depletes GSH and prevents •OH loss. Systematic antimicrobial tests are performed against bacteria using this multienzyme‐integrated nanoplatform. A dual‐mode strategy involving natural enzyme‐enhanced antioxidant capacity and artificial enzyme‐enhanced •OH release to develop an efficient and novel enzyme‐integrated therapeutic platform is integrated.

AbstractThis research evaluated and analyzed the water quality of Zipingpu Reservoir using the Comprehensive Water Quality Index and Nemerow index method, based on monitoring data from 2019 to 2021 at four monitoring sites. It also used temporal and spatial change rate analysis to understand changes in water quality among the four monitoring sites—Aba Aluminum Factory, Chaguan Village, Cross‐reservoir Bridge and Xuankou Village—as well as the reservoir as a whole. The results show that: from the result of comprehensive water quality index, the water quality of Zipingpu Reservoir had improved in 3 years, and the water quality was excellent. The Nemerow index method results for the four monitoring sections in 2019, 2020, and 2021, which varied from 0.37 to 0.47, demonstrated that the reservoir was rated as having high water quality and Class I standard water quality. According to the results of the improved Nemerow pollution index method, the Improved Nemerow pollution index values were all between 0.27 and 0.32 and the water quality was within the Class I range each of the 3 years and fluctuated less. The water quality of the Aba aluminum facility was marginally worse than that of the other three monitoring sites during the monitoring period, according to the spatial rate of change (S/%). The reservoir's water quality improved slightly between 2019 and 2021, according to the temporal rate of change (T/%).
Moral judgment in realistic traffic scenarios: moving beyond the trolley paradigm for ethics of autonomous vehicles
Authors: Cecchini Dario , Brantley Sean , Dubljević Veljko 
Published: November 2023

AbstractThe imminent deployment of autonomous vehicles requires algorithms capable of making moral decisions in relevant traffic situations. Some scholars in the ethics of autonomous vehicles hope to align such intelligent systems with human moral judgment. For this purpose, studies like the Moral Machine Experiment have collected data about human decision-making in trolley-like traffic dilemmas. This paper first argues that the trolley dilemma is an inadequate experimental paradigm for investigating traffic moral judgments because it does not include agents’ character-based considerations and is incapable of facilitating the investigation of low-stakes mundane traffic scenarios. In light of the limitations of the trolley paradigm, this paper presents an alternative experimental framework that addresses these issues. The proposed solution combines the creation of mundane traffic moral scenarios using virtual reality and the Agent-Deed-Consequences (ADC) model of moral judgment as a moral-psychological framework. This paradigm shift potentially increases the ecological validity of future studies by providing more realism and incorporating character considerations into traffic actions.
On abelian subcategories of triangulated categories
Authors: Linckelmann Markus 
Published: November 2023

AbstractThe stable module category of a selfinjective algebra is triangulated, but need not have any nontrivial t-structures, and in particular, full abelian subcategories need not arise as hearts of a t-structure. The purpose of this paper is to investigate full abelian subcategories of triangulated categories whose exact structures are related, and more precisely, to explore relations between invariants of finite-dimensional selfinjective algebras and full abelian subcategories of their stable module categories.
My synthetic wingman must understand me: modelling intent for future manned–unmanned teaming

Published: November 2023

AbstractWith advances in artificial intelligence, machine learning, and cognitive modelling, unmanned aircraft are expected to act as human-like wingmen in the near future. For fluent and effective manned–unmanned teaming, synthetic wingmen must be able to account for and adapt to their partners’ intent with little or no communication. To enable such abilities, it becomes crucial to identify the requirements that makes intent explainable to synthetic wingmen, necessitating approaches to describe and analyse intent from a human-centric perspective. To address this issue, this paper reports on findings from using Work Domain Analysis to design and analyse models of situated intent with six levels of cognitive control (frames, effects, values, generic, implementations, and physical). Through a literature review and seven subject matter expert interviews, a synthesized model was designed to represent fighter pilots’ intent in a manned–unmanned teaming scenario. Using the synthesized model as the context, a transfer of control and a link loss situation were further described and analysed. Experiences show that Work Domain Analysis can provide a practical and applicable means to model situated intent, particularly since designed models can be re-utilised to model intent in similar situations. Furthermore, the model analyses show the importance of accounting for fighter pilots’ adopted frames since small variations of the framing of the situations can propagate throughout the model resulting in conflicting or inconsistent intent. The paper concludes that synthetic wingmen must be able to reason about all six levels of cognitive control, requiring a more holistic approach to make intent explainable.
Does social well-being predict academic resilience and achievement? Analysis of Swedish PISA 2018 data
Authors: Siebecke Deborah Elin 
Published: November 2023

AbstractIn recent years, Sweden has been struggling with issues of educational inequity as the influence of students' socioeconomic status on their academic achievements has amplified. Nonetheless, academically resilient students who demonstrate high achievement despite socioeconomic disadvantages offer hope for a more equitable future. Previous research has primarily focused on the relationship between well-being and academic achievement, with less emphasis on the connection between academic resilience and well-being. Thus, this study investigates the extent to which students’ well-being predicts their academic achievement and resilience, with a special focus on the social well-being of socioeconomically disadvantaged students. Using the Swedish PISA 2018 dataset and structural equation modeling technique, the measurement properties of social well-being were first tested, and its dimensions were then related to students' academic resilience and achievement. The findings reveal that student-reported teacher support positively predicts their academic resilience and achievement, whereas exposure to bullying is detrimental to their academic achievement.
Molecular phylogeny and genetic diversity of the economic seaweed Meristotheca (Gigartinales, Rhodophyta) in the northwest Pacific, with a description of M. pilulaora sp. nov

Published: November 2023

AbstractSpecies of the red algal genus Meristotheca are important natural resources that can be used directly as food for human consumption as well as raw materials for the extraction of carrageenan. Despite being harvested in Japan and Korea, a comprehensive taxonomic study of Meristotheca specimens from these two countries to elucidate their phylogenetic position is lacking. In this study, we aimed to clarify the taxonomic identities of specimens currently regarded as M. papulosa from Korea and Japan by analyzing morphological and molecular data. As the result, we recognized a new species, Meristotheca pilulaora sp. nov. from Korea and resurrected Meristotheca japonica for specimens from Japan. The two entities have long been identified as M. papulosa and exhibit similar external morphologies. They appeared independently in the concatenated phylogenetic tree of COI-5P and rbcL and could also be distinguished morphologically by the position of cystocarps (blade margins in M. pilulaora; marginal proliferations in M. japonica), spinose cystocarps (absent in M. pilulaora; present in M. japonica), and the number of cortical cell layers (two in M. pilulaora; 4–8 in M. japonica). The DNA analysis of M. pilulaora sp. nov. in local populations showed 11 COI-5P haplotypes on Jeju Island with no apparent geographical structure. High genetic diversity and occurrence of unique haplotypes in southern Jeju may provide a genetic basis for population with high thermal tolerance. These findings have strengthened our understanding of the species diversity of the genus Meristotheca and provided insights into conservation, management, and haplotype selection for the future cultivation of these economically important species.
Uncertainties in scheduling and execution of trackwork in Sweden
Authors: Ivina Daria , Olsson Nils O. E. , Palmqvist Carl-William , Hiselius Lena Winslott 
Published: November 2023

AbstractTrackwork planning and scheduling are demanding because they require strategic foresight and must be completed well in advance. In Sweden, trackwork is performed by maintenance contracting companies during an operation period free from trains. In the contractors’ practice, once the maintenance plan is authorised, some unexpected events might interrupt the plan’s execution, leading to uncertainties. The purpose of this study is to identify and classify uncertainties and strategies applied to manage uncertainties in the contractors’ everyday planning and scheduling of trackwork. This work presents semi-structured interviews with foremen and planners at railway maintenance contracting companies in Sweden. The main findings show that in trackwork planning and scheduling, contractors deal with two types of uncertainties: internal and external. We categorised uncertainties and strategies to deal with uncertainties and described them on tactical and operational levels. The majority of the revealed uncertainties led to trackwork rescheduling. Furthermore, we suggest that current strategies to manage uncertainties applied at contracting companies can be improved by revising organisational design strategies for maintenance projects. This work increases the understanding and supports the management of uncertainties in trackwork planning and scheduling.
Erfolgreicher dank Qualifikation und Mentoring? Analysen von Determinanten des beruflichen Erfolgs von Schulleitungen in Deutschland
Authors: Tulowitzki Pierre , Pietsch Marcus , Grigoleit Ella , Köferli Sara 
Published: November 2023

ZusammenfassungVor dem Hintergrund eines zunehmenden Mangels an Schulleitungen in Deutschland erscheint es von zentraler Bedeutung, dass Schulleitungen sich als erfolgreich in ihrem Amt wahrnehmen (subjektiver Berufserfolg) und auch anhand von Faktoren wie Gehalt als erfolgreich erachtet werden können (objektiver Berufserfolg), da sich diese Faktoren auf das Belastungserleben sowie die Motivation auswirken können. Ziel der Studie war es, für Deutschland zu ermitteln, welche Determinanten aus den Bereichen Soziodemographie, (objektiviertes) Humankapital und (organisationale) Förderungsmaßnahmen den Berufserfolg von Schulleitungen beeinflussen. Die Studie nutzt Daten der Studie Leadership in German Schools 2020 (Cramer et al. 2020), die durch die forsa Politik- und Sozialforschung GmbH zwischen September und November 2019 erhoben wurden. Die Grundgesamtheit für die Befragung umfasste alle Schulleitungen an allgemeinbildenden Schulen in Deutschland. In dieser Gruppe wurde eine zufällig ausgewählte und für Deutschland repräsentative Stichprobe von insgesamt n = 405 Schulleitungen mithilfe eines standardisierten und pilotierten Onlinefragebogens befragt.
Die Ergebnisse deuten darauf hin, dass zwischen dem wahrgenommenen Erfolg und universitären Qualifikationen und Qualifikationen an einem Landesinstitut ein tendenzieller Zusammenhang besteht. Zwischen Einkommen und Qualifikationsmaßnahmen und Mentoring konnte hingegen kein statistisch signifikanter Zusammenhang gefunden werden. Weibliche Schulleitungen haben, auch nach Kontrolle einer Vielzahl von Kovariaten, ein geringeres Einkommen als männliche.
Overload and variable amplitude load effects on the fatigue strength of welded joints

Published: November 2023

AbstractDifferent load spectra and individual load peaks might substantially relax high residual stresses as well as induce compressive residual stresses in welded components and, consequently, affect the fatigue performance of these joints. Consideration of peak loads and resulting relaxation of residual stresses in fatigue analyses can substantially enhance the accuracy of life prediction. The aim of the current study is to experimentally investigate the fatigue strength of welded joints subjected to different levels of overloads and variable amplitude (VA) loads and to develop local fatigue assessment method to account for the relaxation of residual stresses via a mean stress correction using the 4R method. The 4R method applies a local stress ratio for the mean stress correction considering material strength, residual stresses, applied stress ratio of external loading and local weld geometry in elastic–plastic material behaviour. Fatigue tests were carried out on fillet-welded longitudinal gusset joints made of S700 high-strength steels under applied stress ratio R = 0–0.1. A mild strength steel (S355) and ultra-high-strength steel (S1100) were selected as reference steel grades for the fatigue testing to study the material strength effects. Numerical analyses were conducted to evaluate the fatigue notch factors using the effective notch stress concept with the reference radius of rref = 1.0 mm and theory of critical distance (TCD) using the point method. The experimental results indicated that a substantial improvement in the fatigue strength capacity can be claimed in the joints subjected to tensile overloads, particularly in the studied S700 and S1100 steels. The higher-level overload (0.8fy), corresponding to the nominal cross-sectional area, improved the mean fatigue strength of the welded joints manufactured of high-strength S700 steel by approximately 60%, while the lower overload (0.6fy) improved the mean fatigue strength by 20%. In addition, a use of equivalent nominal stresses for the joints subjected to VA loads resulted in conservative assessments when employing S–N curves obtained for the CA loading. The 4R method, via the local mean stress correction for individual cycles, provided higher accuracy for the fatigue assessments.
Anomaly Detection with Sub-Extreme Values: Health Provider Billing
Authors: Muspratt Rob , Mammadov Musa 
Published: November 2023

AbstractAnomaly detection within the context of healthcare billing requires a method or algorithm which is flexible to the practicalities and requirements of manual case review, the volumes and associated effort of which can determine whether anomalous output is ultimately actioned or not. In this paper, we apply a modified version of a previously introduced anomaly detection algorithm to address this very issue by enacting refined targeting capability based on the identification of sub-extreme anomalies. By balancing the anomaly identification process with appropriate threshold setting tailored to each sample health provider discipline, it is shown that final candidate volumes are controlled with greater accuracy and sensitivity. A comparison with standard local outlier factor (LOF) scores is included for benchmark purposes.
