Russian Disjunction To li To li and Obligatory Ignorance
Authors: Ivlieva Natalia 
Published: September 2024

Abstract
In this paper, we explore the behavior of one complex disjunction in Russian that has some special properties that set it apart from other simple and complex disjunctions: it never gives rise to free choice inferences in environments in which other disjunctions do and under universal quantifiers it behaves different from other disjunctions. We show that the data resist an analysis in terms of wide scope disjunction and propose that those special properties are due to obligatory ignorance inferences associated with this disjunction. The paper provides one more argument for a grammatical theory of ignorance along the lines of ( 7).

ABSTRACT
The diffuse stellar component of galaxy clusters made up of intergalactic stars is termed the intracluster light (ICL). Although there is a developing understanding of the mechanisms by which the ICL is formed, no strong consensus has yet been reached on which objects the stars of the ICL are primarily sourced from. We investigate the assembly of the ICL starting approximately 10 Gyr before $z=0$ in 11 galaxy clusters (halo masses between $\sim 1\times 10^{14}$ and $\sim 7\times 10^{14}$ M$_{\odot }$ at $z\approx 0$) in the Horizon-AGN simulation. By tracking the stars of galaxies that fall into these clusters past cluster infall, we are able to link almost all of the $z\approx 0$ ICL back to progenitor objects. Satellite stripping, mergers, and pre-processing are all found to make significant contributions to the ICL, but any contribution from in situ star formation directly into the ICL appears negligible. Even after compensating for resolution effects, we find that approximately 90 per cent of the stacked ICL of the 11 clusters that is not pre-processed should come from galaxies infalling with stellar masses above $10^{9}$ M$_{\odot }$, with roughly half coming from infalling galaxies with stellar masses within half a dex of $10^{11}$ M$_{\odot }$. The fact that the ICL appears largely sourced from such massive objects suggests that the ICL assembly of any individual cluster may be principally stochastic.
An explanation for the slow-rise phase of solar eruptions
Authors: Xing Yaoyu , Duan Aiying , Jiang Chaowei 
Published: September 2024

ABSTRACT
Solar eruptions are sudden release of the magnetic free energy accumulated within a quasi-static evolutionary process of the corona. Interestingly, many solar eruptions are preceded by a short-term slow-rise phase, during which the pre-eruption structure rises at a speed significantly larger than that of the quasi-static evolution. Here we suggest an explanation for the slow-rise phase based on a recent high-accuracy magnetohydrodynamic simulation for initiation of solar eruption. The simulation shows that by continuously shearing a bipolar magnetic arcade, an internal current sheet forms gradually, and an eruption begins once magnetic reconnection is triggered at the current sheet. We find in the simulation that the overlying field presents a slow-rise phase before the reconnection sets in. In addition, the rising speed is significantly larger than that of the core field during this phase. This slow rise is a manifestation of the growing expansion of the arcade in the process of approaching a fully open field state, which is inherent to the formation of a current sheet before the eruption. We also show three flare events with slow-rise phases that are highly consistent with these key characteristics in the simulation: an expansion of the overlying coronal loops with speeds much larger than the quasi-static evolution speed, and for those events with filament eruption, the slow rise of filament is much smaller than that of the overlying loops. In this type of events, the eruption might be initiated through the mechanism as shown in the simulation, and the expansion of overlying coronal loops is a better indicator of the slow-rise phase.

ABSTRACT
V745 Sco is a Galactic symbiotic recurrent nova with nova eruptions in 1937, 1989, and 2014. We study the behaviour of V745 Sco at radio wavelengths (0.6–37 GHz), covering both its 1989 and 2014 eruptions and informed by optical, X-ray, and $\gamma$-ray data. The radio light curves are synchrotron-dominated. Surprisingly, compared to expectations for synchrotron emission from explosive transients such as radio supernovae, the light curves spanning 0.6–37 GHz all peak around the same time ($\sim$18–26 d after eruption) and with similar flux densities (5–9 mJy). We model the synchrotron light curves as interaction of the nova ejecta with the red giant wind, but find that simple spherically symmetric models with wind-like circumstellar material (CSM) cannot explain the radio light curve. Instead, we conclude that the shock suddenly breaks out of a dense CSM absorbing screen around 20 d after eruption, and then expands into a relatively low-density wind ($\dot{M}_{out} \approx 10^{-9}\!-\!10^{-8}$ M$_{\odot }$ yr$^{-1}$ for $v_w = 10$ km s$^{-1}$) out to $\sim$1 yr post-eruption. The dense, close-in CSM may be an equatorial density enhancement or a more spherical red giant wind with $\dot{M}_{in} \approx [5\!-\!10] \times 10^{-7}$ M$_{\odot }$ yr$^{-1}$, truncated beyond several $\times 10^{14}$ cm. The outer lower-density CSM would not be visible in typical radio observations of Type Ia supernovae: V745 Sco cannot be ruled out as a Type Ia progenitor based on CSM constraints alone. Complementary constraints from the free–free radio optical depth and the synchrotron luminosity imply the shock is efficient at accelerating relativistic electrons and amplifying magnetic fields, with $\epsilon _e$ and $\epsilon _B \approx 0.01\!-\!0.1$.
Molecular clouds as hubs in spiral galaxies: gas inflow and evolutionary sequence
Authors: Zhou J W , Dib Sami , Davis Timothy A 
Published: September 2024

ABSTRACT
We decomposed the molecular gas in the spiral galaxy NGC 628 (M74) into multiscale hub-filament structures using the CO (2$-$1) line by the dendrogram algorithm. All leaf structures as potential hubs were classified into three categories, i.e. leaf-HFs-A, leaf-HFs-B and leaf-HFs-C. Leaf-HFs-A exhibit the best hub-filament morphology, which also have the highest density contrast, the largest mass and the lowest virial ratio. We employed the filfinder algorithm to identify and characterize filaments within 185 leaf-HFs-A structures, and fitted the velocity gradients around the intensity peaks. Measurements of velocity gradients provide evidence for gas inflow within these structures, which can serve as a kinematic evidence that these structures are hub-filament structures. The numbers of the associated 21 μm and H α structures and the peak intensities of 7.7 μm, 21 μm, and H α emissions decrease from leaf-HFs-A to leaf-HFs-C. The spatial separations between the intensity peaks of CO and 21 μm structures of leaf-HFs-A are larger than those of leaf-HFs-C. These evidence indicate that leaf-HFs-A are more evolved than leaf-HFs-C. There may be an evolutionary sequence from leaf-HFs-C to leaf-HFs-A. Currently, leaf-HFs-C lack a distinct gravitational collapse process that would result in a significant density contrast. The density contrast can effectively measure the extent of the gravitational collapse and the depth of the gravitational potential of the structure which, in turn, shapes the hub-filament morphology. Combined with the kinematic analysis presented in previous studies, a picture emerges that molecular gas in spiral galaxies is organized into network structures through the gravitational coupling of multiscale hub-filament structures. Molecular clouds, acting as knots within these networks, serve as hubs, which are local gravitational centres and the main sites of star formation.
E-Cigarette Brand Use by Race/Ethnicity in a US Sample of Adolescent and Young Adult E-Cigarette Users, 2022–2023

Abstract

Introduction
To determine whether e-cigarette brand use varies according to race/ethnicity among adolescent and young adult e-cigarette users.

Aims and Methods
Data are from a cross-sectional online survey of respondents aged 15–24 years (January 2022–June 2023; 300 unique respondents/week). The analytic sample was restricted to current e-cigarette users (n = 6387). Respondents selected their usual brand and reported frequency of past 30-day e-cigarette use (in days). ANOVAs measured differences in frequency of use by usual brand, stratified by race/ethnicity. Linear regression identified changes in usual brand over time by race/ethnicity, controlling for age and use of other tobacco/nicotine products.

Results
One-quarter (25.6%) of Black and 22.2% of Hispanic e-cigarette users reported JUUL as their usual brand, compared to those who are White (15.7%) or another race (16.5%). Puff Bar was the second-most reported brand among Black (15.1%) or Hispanic (16.6%) e-cigarette users, to a greater extent than White (7.8%) e-cigarette users. Frequency of use varied significantly according to respondents’ usual brand when stratified by race/ethnicity (p &lt; .001).

Conclusions
Across all racial and ethnic categories, frequency of use was greater for brands marketed with more flavor options and containing nicotine (EB Design, SMOK, Hyde, and Vuse). Despite declines in popularity, Black or Hispanic respondents report using JUUL and Puff Bar to a greater extent than other respondents, and vape less frequently than White non-Hispanic respondents regardless of brand. As e-cigarette brands continue to proliferate, monitoring e-cigarette brand selection by race/ethnicity can inform studies of nicotine exposure, polyuse, and health disparities.

Implications
Our study demonstrates the importance of research methods to detect rapidly changing patterns of e-cigarette use by race/ethnicity and age. The inclusion of measures capturing brand use can detect evidence of product features and targeted marketing that may have consequences for patterns of tobacco use and nicotine exposure among these groups.

Published: September 2024

Abstract
Introduction: Pancreatic lesions have varied morphology and presentation making their diagnosis challenging. The lesions may be asymptomatic incidentalomas on abdominal imaging for other conditions, symptomatic producing specific hormone effects or causing local effects. Case: We report a 35-year-old woman with recurrent abdominal pain confirmed gastroesophageal reflux disease. Initial CT imaging reported findings of a pancreatic pseudocysts. A careful review of the imaging showed cystic dilatation of the main pancreatic duct mimicking a main pancreatic duct intra-ductal papillary mucinous neoplasm. At surgery, a small nodule palpated in the pancreatic head with sacculation in the body and tail. A histopathological review showed a pancreatic neuroendocrine tumour blocking the main pancreatic duct at the neck causing downstream dilatation and sacculation. This case highlights the difficulty of diagnosing small asymptomatic pancreatic tumours especially with limited range of imaging modalities while increasing awareness of these conditions to improve our ability to manage them effectively.
Transcription factors WRKY2 and WRKY34 control LATERAL ORGAN BOUNDARIES DOMAIN10 expression in pollen vegetative cell nuclei
Authors: Nguyen Thu-Hien , Kim Min Jung , Kim Jungmook 
Published: September 2024

Abstract
The intricate regulation of gene expression determining cell fate during male gametogenesis involves a complex interplay of multiple transcriptional regulators. In Arabidopsis (Arabidopsis thaliana), the LATERAL ORGAN BOUNDARIES DOMAIN 10 (LBD10) transcription factor is prominent in early microspores and both the germ and vegetative cells of bicellular pollen, playing an important role in pollen development. However, in mature pollen, LBD10 exclusively localizes in the vegetative cell nucleus (VCN). Here, we identify cis-acting elements and trans-acting factors responsible for the specific expression of LBD10 in the VCN during pollen maturation. Using a series of LBD10 promoter deletion constructs fused with GUS or GFP reporters, we pinpoint two crucial core promoter sequences. These sequences are situated within two 200 bp regions upstream of the start codon and independently govern LBD10 expression in the VCN. We demonstrate that a W-box motif (AGTCAC) at −770 bp is essential for activating the expression of LBD10 in vegetative cells during pollen maturation. Our transient gene expression assays using Arabidopsis protoplasts and chromatin immunoprecipitation assays show that the transcription factors WRKY2 and WRKY34 recognize the LBD10 promoter region containing W-box motifs. Collectively, our findings suggest that WRKY2 and WRKY34 binding to the W-box motifs plays a role in the VCN-specific expression of LBD10 in pollen. This interaction may contribute to male gametophyte development, shedding light on the intricate regulatory network governing this critical biological process.

Abstract
In many eukaryotic algae, CO2 fixation by Rubisco is enhanced by a CO2-concentrating mechanism, which utilizes a Rubisco-rich organelle called the pyrenoid. The pyrenoid is traversed by a network of thylakoid membranes called pyrenoid tubules, which are proposed to deliver CO2. In the model alga Chlamydomonas (Chlamydomonas reinhardtii), the pyrenoid tubules have been proposed to be tethered to the Rubisco matrix by a bestrophin-like transmembrane protein, BST4. Here, we show that BST4 forms a complex that localizes to the pyrenoid tubules. A Chlamydomonas mutant impaired in the accumulation of BST4 (bst4) formed normal pyrenoid tubules, and heterologous expression of BST4 in Arabidopsis (Arabidopsis thaliana) did not lead to the incorporation of thylakoids into a reconstituted Rubisco condensate. Chlamydomonas bst4 mutants did not show impaired growth under continuous light at air level CO2 but were impaired in their growth under fluctuating light. By quantifying the non-photochemical quenching (NPQ) of chlorophyll fluorescence, we propose that bst4 has a transiently lower thylakoid lumenal pH during dark-to-light transition compared to control strains. We conclude that BST4 is not a tethering protein but is most likely a pyrenoid tubule ion channel involved in the ion homeostasis of the lumen with particular importance during light fluctuations.
Exploring police employees’ attitudes and behaviours as a bystander towards police sexual misconduct
Authors: Bubbear Rogers Ellie , Sweeting Fay 
Published: September 2024

Abstract
Police sexual misconduct (PSM) can have a severe impact on the police workforce, affecting all police personnel, not just officers, but it has received little academic attention. Such misconduct often goes unreported, despite many instances having bystanders present. This research explored police employees’ attitudes and behaviours as a bystander towards PSM. Four focus groups involving 25 police personnel were conducted across three forces in the East of England, and the data were analysed using thematic analysis. The findings revealed that participants’ attitudes towards sexual misconduct varied based on their perception of the misconduct and that barriers deterred them from reporting or challenging such behaviours. Nevertheless, participants felt accountable to act as bystanders while also holding other personnel responsible.

Published: September 2024

Abstract
Schizophrenia is a complex disorder characterized by multiple neurochemical abnormalities and structural changes in the brain. These abnormalities may begin before recognizable clinical symptoms appear and continue as a dynamic process throughout the illness. Recent advances in imaging techniques have significantly enriched our comprehension of these structural alterations, particularly focusing on gray and white matter irregularities and prefrontal, temporal, and cingulate cortex alterations. Some of the changes suggest treatment resistance to antipsychotic medications, while treatment nonadherence and relapses may further exacerbate structural abnormalities. This narrative review aims to discuss the literature about alterations and deficits within the brain, which could improve the understanding of schizophrenia and how to interpret neurostructural changes.
Designing, delivering and evaluating a specialty specific quality improvement course for the rheumatology multidisciplinary team

Published: September 2024

Abstract

Objectives
Quality improvement (QI) methodology aims to drive improvement in healthcare using a systematic approach. QI is an integral part of healthcare professional training curricula. However, many members of the rheumatology community have not accessed formal QI methodology training, including those expected to supervise QI activity. The BSR QI practical methodology workshop was created to address this knowledge gap in a specialty-specific course designed and delivered by, and for, the multidisciplinary team.

Methods
Course design centred on the Institute for Healthcare Improvement approach, ‘Model for improvement’, adapting materials from the well-established Trainees Improving Patient Safety through QI (TIPSQI) initiative. The course was delivered online (2021) and face-to-face (2022). Kolbs’ four stage experiential learning cycle informed course design utilising rheumatology-specific cases and facilitated breakout rooms to teach QI tools.
Kirkpatrick’s four-stage model was used to design the course evaluation. Data from surveys completed before, immediately after, and six months’ following the courses were used to evaluate the course.

Results
Baseline knowledge of specific QI tools was limited. Post course evaluation demonstrated increased confidence to use and teach tools. Sustained confidence to contribute to and lead QI activity was reported. Course satisfaction was high; 100% of delegates would recommend the course to colleagues.

Conclusion
This successful, rheumatology specific QI course led to improved delegate knowledge of QI methodology and confidence in leading and teaching QI initiatives. It has contributed to building momentum in a growing rheumatology QI community of practice and to embedding a sustainable culture of improvement across the rheumatology community.

Abstract
The objective of the study is to evaluate natural radioactivity and its radiological impact on the health of the populace within Cape Coast North. Soil and water samples were taken and analysed using a high purity germanium (HPGe) detector. Results for the average activity concentrations of 226Ra, 232Th, and 40K in soil samples range from 15.0 to 60.8 Bq/kg with a mean of 20.9 ± 7.2 Bq/kg, 16.3 to 97.2 Bq/kg with a mean of 43.8 ± 2.4 Bq/kg, and 4.7 to 411.4 Bq/kg with an average of 140.6 ± 4.2 Bq/kg, respectively. The absorbed dose rate in air and outdoor annual effective dose to the public were estimated to be 46.6 nGyh−1 and 0.1 mSv, respectively, which fell below the recommended average. The average activity concentrations of 226Ra, 232Th, and 40K in water samples were 1.4, 0.4, and 1.2 Bq/L, respectively. The annual effective dose is 0.4 mSv, which is greater than the WHO recommended level of 0.1 mSv/y.
Trajectories of Public Islam: Public Religious Expressions among American Muslim Advocates
Authors: Cantori Valentina 
Published: September 2024

Abstract
In American mainstream cultural discourse, Islam is often constructed as undemocratic, violent, and un-American. How do American Muslim advocates react to these tarnished representations of their religion? This paper examines the ways in which Muslim advocates construct public discourse around Islam by exploring the possibilities for and recognizing the constraints on their public religious expressions in U.S. civic life as advocates navigate cultural templates infused with de-sacralized Christian meanings. Based on participant observation in two Muslim advocacy organizations, the article demonstrates that advocates map Islam differently, depending on whether the imagined audience of their public discourse is other Muslims or non-Muslims. When advocates imagine addressing non-Muslims, the public discourse of both groups similarly emphasizes Islamic compatibility of Muslim with American values. Among both groups, there is a process of filtering certain religious expressions for more expansive social maps that uncovers the unequal power dynamics shaping trajectories of public religion in civic life for one of the most stigmatized ethno-religious groups in the United States today. This paper contributes to expanding our understanding of how civic culture enables and constrains historically marginalized groups’ attempts at redefining belonging.
After Restructuring: Understanding Religion, Nonreligion, and Spirituality in the Twenty-First Century
Authors: Edgell Penny 
Published: September 2024

Abstract
The Restructuring of American Religion (1988) provided a still-influential framework for the study of American religion that centered the emergence, after World War II, of a left–right religio-political divide driving mobilization around conflicts understood as moral. But in the last 30 years, the landscape of American religion has been transformed by decline in commitment to mainstream religious institutions, especially white Christian ones, and by the emergence of large groups of Americans who are religiously indifferent or who embrace spirituality or nonreligion. A new framework is needed to account for this transformed landscape. This framework must avoid problems characteristic of earlier approaches by conceiving of morals and interests as mutually constitutive, centering whiteness, racialization, and the defense of heteropatriarchy in explaining religio-political conflict, integrating the study of nonreligion and spirituality and religion, and analyzing not only decline in religious commitment but the changing meaning of religious identity in a transformed landscape.
