Influence of the abrasive shape-position characteristic on the grinding thermo-mechanical coupling
Authors: Sun Cong , Zhang He , Xu Chunwei , Hong Yuan , Xiu Shichao 
Published: December 2023

AbstractGrinding is a generally utilized method, removing excess materials through effective abrasives. The grinding abrasives with multiple shape-position characteristics play a dominant role in determining the thermo-mechanical coupling, which may influence the surface quality directly. To investigate this correlated influence mechanism, this paper focuses on the abrasive shape and position characteristic on the grinding thermo-mechanical process with the analytic single abrasive interaction force model by considering the abrasive shape and its distribution information. It can be found that the mapped dynamic grinding temperature is actually discretized on the workpiece surface, which is on account of the diversity of the abrasive shape and its distribution. Moreover, higher spherical and conical abrasive particles, as well as lower pyramid shaped abrasive particle ratios, can generate greater specific grinding energy with a discretized temperature distribution, when compared with a higher proportion of pyramid shaped abrasive. The study can be utilized to provide valuable theoretical foundation for engineering practice by preparing structural wheel and its grinding property.

Abstract

Objective:
Up to 10% of patients report penicillin allergy (PA), although only 1% are truly affected by Ig-E-mediated allergies. PA has been associated with worse postoperative outcomes, but studies on the impact of reported PA in cancer patients are lacking, and especially in these multimorbid patients, a non-complicated course is of utmost importance.

Methods:
Retrospective analysis of patients undergoing elective oncological surgery at a tertiary reference center. Data on surgical site infections (SSI), postoperative complications (measured by Clavien-Dindo classification and Comprehensive Complication Index (CCI)), hospitalization duration, and treatment costs were collected.

Results:
Between 09/2019 and 03/2020, 152 patients were identified. 16/152 patients (11%) reported PA, while 136/152 (89%) did not. There were no differences in age, BMI, Charlson Comorbidity Index, and smoking status between groups (p > 0.4). Perioperative beta-lactam antibiotics were used in 122 (89.7%) and 15 (93.8%) patients without and with reported PA, respectively. SSI and mean numbers of infections occurred non-significantly more often in patients with PA (p = 0.2 and p = 0.47). The median CCI was significantly higher in PA group (26 vs. 51; p = 0.035). The median hospitalization duration and treatment costs were similar between non-PA and PA groups (4 vs 3 days, p = 0.8; 16’818 vs 17’444 CHF, p = 0.4).

Conclusions:
In patients undergoing cancer surgery, reported PA is common. Failure to question the unproven PA may impair perioperative outcomes. For this reason, patient and provider education on which reactions constitute a true allergy would also assist in allergy de-labeling. In addition, skin testing and oral antibiotic challenges can be performed to identify the safe antibiotics and to de-label appropriate patients.
Aggregation strategies to improve XAI for geoscience models that use correlated, high-dimensional rasters

Abstract
Complex machine learning architectures and high-dimensional gridded input data are increasingly used to develop high-performance geoscience models, but model complexity obfuscates their decision-making strategies. Understanding the learned patterns is useful for model improvement or scientific investigation, motivating research in eXplainable artificial intelligence (XAI) methods. XAI methods often struggle to produce meaningful explanations of correlated features. Gridded geospatial data tends to have extensive autocorrelation so it is difficult to obtain meaningful explanations of geoscience models. A recommendation is to group correlated features and explain those groups. This is becoming common when using XAI to explain tabular data. Here, we demonstrate that XAI algorithms are highly sensitive to the choice of how we group raster elements. We demonstrate that reliance on a single partition scheme yields misleading explanations. We propose comparing explanations from multiple grouping schemes to extract more accurate insights from XAI. We argue that each grouping scheme probes the model in a different way so that each asks a different question of the model. By analyzing where the explanations agree and disagree, we can learn information about the scale of the learned features. FogNet, a complex three-dimensional convolutional neural network for coastal fog prediction, is used as a case study for investigating the influence of feature grouping schemes on XAI. Our results demonstrate that careful consideration of how each grouping scheme probes the model is key to extracting insights and avoiding misleading interpretations.
The state role in civilising childcare – comparing policy intentions with childcare in Brazil and Denmark

Published: December 2023

AbstractIt has become universal to claim a relationship between social cohesion and quality public childcare. The more we invest in our children, the better the return later in life. We explore how childcare is used to strengthen social life by comparing the state role in civilising childcare as described in policy and educational guidelines. At one level, we find that policy intentions are framed by the idea of using childcare to reduce inequalities between people and social groups, and at another by the idea of civilising children to adapt to existing social structures. The analysis unfolds these two sets of intentions by showing how pedagogical ideas of child development become linked to the ways two very different states – Brazil and Denmark – formulate and organise ECEC policies as well as using childcare to bridge between people and social groups, and to civilising children to adapt to existing social structures.
Health Inequities Among People Who Use Drugs in a Post-Dobbs America: The Case for a Syndemic Analysis
Authors: Carroll Jennifer J. , Ostrach Bayla , El-Sabawi Taleed 
Published: December 2023

AbstractPunitive policy responses to substance use and to abortion care constitute direct attacks on personal liberty and bodily autonomy. In this article, we leverage the concept of “syndemics” to anticipate how the already synergistic stigmas against people who use drugs and people who seek abortion services will be further compounded the Dobbs decision.
New findings of Decapoda (Crustacea) in the Callovian of the Ryazan region (Central European Russia)
Authors: Dadykin Ivan A. , Shmakov Alexey S. 
Published: December 2023

AbstractThe decapod crustaceans of Central European Russia have been the subject of studies since the nineteenth century, and the only species, Eryma quadriverrucatum Trautschold, 1866 (Erymidae), has been found in the Callovian to the Oxfordian of that region. The present paper discusses the new exceptional findings of Solenoceridae, Glypheidae, and Mecochiridae from the upper Callovian sites of the Ryazan Region. The previously reported presence of Archeosolenocera sp. is confirmed in detail; Glypheopsis aff. G. etalloni (Oppel, 1861) and Eumorphia sp. are noticed for the first time for this area. Modern identification of erymids is reported: Eryma aff. E. ventrosum (von Meyer, 1835), E. ornatum (Quenstedt, 1858), and Stenodactylina insignis (Oppel, 1862) are noted in addition to E. quadriverrucatum. These findings address the gaps in the fragmented knowledge about the decapod fauna of Central European Russia and exhibit a differentiation of the local Russian decapod assemblage from those of Western Europe. The decapod community of the Ryazan region is considered to be associated with soft substrates of upper sublittoral zone.
Raids, Resistance, and Retribution: South Africa's Cato Manor Killings, 1960–1
Authors: Kynoch Gary 
Published: December 2023

AbstractOn 24 January 1960 nine police were killed in the African settlement of Cato Manor when residents turned on officers conducting a liquor patrol. On 5 September 1961, nine men convicted of the killings were hanged in Pretoria's Central Prison. These deaths produced contrasting narratives, one by the apartheid state and then decades later, another by the current African National Congress government. Apartheid police and judicial authorities vilified the accused as the worst kind of killers who wantonly slaughtered the representatives of law and order. Sixty years later, these murderers of the apartheid period were resurrected as martyrs and their remains were interred at Heroes Arch, a resting place for many antiapartheid activists. Moving past these binary versions allows us to consider a more mundane story that underscores the South African state's commitment to a model of policing that generated an unmatched degree of persecution in colonial Africa.

Published: December 2023

AbstractKnowledge about parasitic diseases of wildlife will help us to understand the dynamics of parasites and their effects on host populations. The capybara (Hydrochoerus hydrochaeris) is the largest living rodent in the world, and its distribution is associated with the presence of tropical and subtropical wetlands in South America. The Los Padres Lake Integral Reserve (LPLIR) is an important conservation zone in the pampean region of Argentina. One of the emblematic species found within the reserve is the capybara. The objective of this study was to determine the gastrointestinal parasites present in wild capybaras of the LPLIR and to compare different coprological methodologies. Free-ranging capybara fresh feces from 57 individuals were randomly collected from the area of LPLIR in the summer of 2022. Three different techniques were applied: spontaneous sedimentation technique (SS), INTA modified McMaster technique (MM), and Mini-FLOTAC (MF) technique. Fifty-six samples from all samples analysed (56/57, 98%) were found to be positive for gastrointestinal parasites. Two species of Strongylida,Protozoophaga obesa,Echinocoleus hydrochaeris, one unidentified nematode, one unidentified spirurid, and at least two morphotypes ofEimeriaspp. oocysts were recorded. There were found significant differences in the proportion of positive samples and in richness by technique, but no significant differences were found in parasite counting. In conclusion, the choice of methodology depends on the specific objectives of the study. This is the first parasitological study of capybaras from the LPLIR and represents an exploration of parasite communities present in these wild rodents at their southernmost distribution.

AbstractBackgroundMaternal anxiety, depression, and stress during and after pregnancy are negatively associated with child cognitive development. However, the contribution of positive maternal experiences, such as social support, to child cognitive development has received less attention. Furthermore, how maternal experience of social support during specific developmental periods impacts child cognitive development is largely unknown.MethodsUsing data from the Avon Longitudinal Study of Parents and Children (ALSPAC; n = 5784) and the Prediction and Prevention of Preeclampsia and Intrauterine Growth Restriction study (PREDO; n = 420), we investigated the associations between maternal perceived social support during and after pregnancy and child's general cognitive ability at 8 years of age, assessed with the Wechsler Intelligence Scale for Children (WISC). Bayesian relevant life course modeling was used to investigate timing effects of maternal social support on child cognitive ability.ResultsIn both cohorts, higher maternal perceived social support during pregnancy was associated with higher performance on the WISC, independent of sociodemographic factors and concurrent maternal symptoms of depression and anxiety. In ALSPAC, pregnancy emerged as a sensitive period for the effects of perceived social support on child cognitive ability, with a stronger effect of social support during pregnancy than after pregnancy on child cognitive ability.ConclusionsOur findings, supported from two prospective longitudinal cohorts, suggest a distinct role of maternal perceived social support during pregnancy for cognitive development in children. Our study suggests that interventions aimed at increasing maternal social support during pregnancy may be an important strategy for promoting maternal and child well-being.
Cognates are advantaged over non-cognates in early bilingual expressive vocabulary development
Authors: MITCHELL Lori , TSUI Rachel Ka-Ying , BYERS-HEINLEIN Krista 
Published: December 2023

AbstractBilinguals need to learn two words for most concepts. These words are called translation equivalents, and those that also sound similar (e.g., banana–banane) are called cognates. Research has consistently shown that children and adults process and name cognates more easily than non-cognates. The present study explored if there is such an advantage for cognate production in bilinguals’ early vocabulary development. Longitudinal expressive vocabulary data were collected from 47 English–French bilinguals starting at 16–20 months up to 27 months (a total of 219 monthly administrations in both English and French). Children produced a greater proportion of cognates than non-cognates, and the interval between producing a word and its translation equivalent was about 10–15 days shorter for cognates than for non-cognates. The findings suggest that cognate learning is facilitated in early bilingual vocabulary development, such that phonological overlap supports bilinguals in learning phonologically similar words across their two languages.
“You’re Not Understood, and You’re Isolated”: A Narrative Account of Loneliness by Black Older Adults in Ontario, Canada

Published: December 2023

AbstractLoneliness among older adults is a leading health and social concern globally and in Canada, including racialized and minoritized groups. Although previous studies have explored loneliness among ethnic minoritized groups in Canada, little is known about the constellating factors contributing to loneliness among native-born and immigrant Black older adults (BOAs) in Canada and their unique ways of dealing with the experience. Our study explores the constellating factors shaping loneliness experiences among BOAs living in Ontario. Using a narrative approach, we purposively selected and interviewed 13 BOAs. Time as a driver of change, a sense of belonging reinforced through place identity, and challenges of making a new home were dominant themes. Our finding highlights the need for increased cultural sensitivity at the micro and macro levels, which will improve a sense of belonging and reduce loneliness among racialized immigrant older adults.
Pre-stimulus bioelectrical activity in light-adapted ERG under blue versus white background

Published: December 2023

Abstract
To compare the baseline signal between two conditions used to generate the photopic negative response (PhNR) of the full-field electroretinogram (ERG): red flash on a blue background (RoB) and white flash on a white background (LA3). The secondary purpose is to identify how the level of pre-stimulus signal affects obtaining an unambiguous PhNR component. A retrospective chart review was conducted on four cohorts of patients undergoing routine ERG testing. In each group, LA3 was recorded the same way while RoB was generated differently using various luminances of red and blue light. The background bioelectrical activity 30 ms before the flash was extracted, and the root mean square (RMS) of the signal was calculated and compared between RoB and LA3 using Wilcoxon test. Pre-stimulus noise was significantly higher under RoB stimulation versus LA3 in all four conditions for both right and left eyes (ratio RoB/LA3 RMS 1.70 and 1.57 respectively, p < 0.033). There was also no significant difference between the RMS of either LA3 or RoB across protocols, indicating that the baseline noise across cohorts were comparable. Additionally, pre-stimulus noise was higher in signals where PhNR was not clearly identifiable as an ERG component versus signals with the presence of unambiguous PhNR component under RoB in all four groups for both eyes (p < 0.05), whereas the difference under LA3 was less pronounced. Our study suggests that LA3 produces less background bioelectrical activity, likely due to decreased facial muscle activity. As it seems that the pre-stimulus signal level affects PhNR recordability, LA3 may also produce a better-quality signal compared to RoB. Therefore, until conditions for a comparable bioelectrical activity under RoB are established, we believe that LA3 should be considered at least as a supplementary method to evaluate retinal ganglion cell function by ERG.
Investigating the Impact of an Exsolved H2O‐CO2 Phase on Magma Chamber Growth and Longevity: A Thermomechanical Model

Published: December 2023

AbstractMagmatic volatiles drive pressure, temperature, and compositional changes in upper crustal magma chambers and alter the physical properties of stored magmas. Previous studies suggest that magmatic H2O content influences the growth and longevity of silicic chambers through regulating the size and frequency of eruptions and impacting the crystallinity‐temperature curve. However, there has been comparatively little exploration of how CO2 impacts the evolution of magma chambers despite the strong influence of CO2 on H2O solubility and the high concentrations of CO2 often present in mafic systems. In this study, we integrate the thermodynamic effects of dissolved and exsolved H2O and CO2 with the mechanics of open‐system magma chambers that interact thermally and mechanically with the crust. We applied this model to investigate how intrinsic variations in magmatic H2O‐CO2 content influence the growth and longevity of silicic and mafic magma chambers. Our findings indicate that even with a tenfold increase in CO2 content (up to 10,000 ppm), CO2 plays a minimal role in long‐term chamber growth and longevity. While CO2 content affects the magma compressibility, the resulting changes in eruption mass are balanced out by a commensurate change in eruption frequency so that the time‐averaged eruptive flux and long‐term chamber behavior remain similar. In contrast, H2O content strongly influences chamber growth and longevity. In silicic systems, high H2O contents hinder magma chamber growth by increasing the total eruptive flux and steepening the slope of the crystallinity‐temperature curve. In mafic systems, high H2O contents promote magma chamber growth by flattening the slope of the crystallinity‐temperature curve.
The Effect of Different Implementations of the Weak Temperature Gradient Approximation in Cloud Resolving Models
Authors: Wong N. Z. , Kuang Z. 
Published: December 2023

AbstractThe Weak Temperature Gradient (WTG) approximation is a popular method used to couple convection in limited‐area domain simulations with large‐scale dynamics. However, several different schemes have been created to implement this approximation, and these different WTG schemes show a wide range of different results in an idealized framework. Our investigation shows that different model behavior is caused by the treatment of the different baroclinic modes by the different WTG schemes. More specifically, we hypothesize that the relative strengths of the baroclinic modes plays a large role in these differences, and show that modifying these schemes such that they treat the baroclinic modes in a similar manner accounts for many of the significant differences observed.
Seismic Autocorrelation Analysis of Deep Mars
Authors: Deng Sizhuang , Levander Alan 
Published: December 2023

AbstractThe InSight mission deployed one seismic station on Mars, providing a chance to apply single‐station‐based autocorrelation analysis to investigate Martian subsurface structures. However, recent analysis indicated the low‐frequency autocorrelation signals may originate from quasi‐periodic high‐amplitude instrumental “glitches” rather than the reflection response of deep Mars. In this study, we detected and removed these high‐amplitude glitches in raw seismic data and employed autocorrelation on the clean vertical component waveforms filtered between 0.05 and 0.1 Hz. We observed signals at the expected times for the olivine‐wadsleyite transition and core‐mantle boundary (CMB) as estimated by other methods. This result suggests that the low‐frequency autocorrelation signals are the reflection response from the olivine‐wadsleyite transition in the mantle and the Martian CMB region, rather than a noise phenomena. A grid search method to fit the observed PcP waveform was used to identify a layer intermediate in velocity between the Martian mantle and core at the Martian CMB.
Tropical Origins of the Pacific Meridional Mode Associated With the Nonlinear Interaction of ENSO With the Annual Cycle
Authors: Jiang Feng , Zhang Wenjun , Boucharel Julien , Jin Fei‐Fei 
Published: December 2023

AbstractThe Pacific Meridional Mode (PMM) has long been associated with extra‐tropical air‐sea coupling processes, which are thought to influence the development of El Niño‐Southern Oscillation (ENSO). Here we show that the PMM on seasonal to interannual timescales is closely associated with a newly proposed tropical mode known as the ENSO Combination mode (C‐mode), which arises from the nonlinear interaction between ENSO and the background annual cycle in the deep tropics. The PMM exhibits a remarkable resemblance with the C‐mode in atmospheric patterns, spectral characteristics, and local impacts. Based on a simple Hasselmann‐type model, we further demonstrate that the C‐mode‐related atmospheric anomalies can effectively drive PMM‐like sea surface temperature anomalies. As the C‐mode captures seasonally modulated ENSO characteristics, the seasonal‐to‐interannual PMM variability could naturally establish a connection with ENSO, thereby offering an alternative explanation for the observed relationship between PMM and ENSO.
