Abstract
Purpose
This study aimed to assess the safety and efficacy of endoscopic submucosal dissection (ESD) and pre-cutting endoscopic mucosal resection (pEMR) in treating non-ampullary duodenal subepithelial lesions (NADSELs) and to evaluate the clinical utility of endoscopic ultrasound (EUS) before endoscopic resection (ER).

Methods
In this retrospective single-centre cohort study, we compared the clinical outcomes of patients with NADSELs who underwent ESD or pEMR between January 2014 and June 2023. The accuracies of EUS in determining the pathological type and origin of the lesions were evaluated using postoperative histopathology as the gold standard.

Results
Overall, 56 patients with NADSELs underwent ER in this study, including 16 and 40 treated with pEMR and ESD, respectively. There were no significant differences between the two groups in terms of en bloc resection rate, complete (R0) resection rate, perioperative complication rate, and postoperative hospital length of stay (P > 0.05). However, the pEMR group had significantly shorter median operational (13.0 min vs. 30.5 min, P < 0.001) and mean fasting (1.9 days vs. 2.8 days, P = 0.006) time and lower median hospital costs (¥12,388 vs. ¥19,579, P = 0.002). The accuracies of EUS in determining the pathological type and origin of the lesions were 76.8% and 94.6%, respectively, compared with histopathological evaluation.

Conclusions
EUS can accurately predict the origin of NADSELs. Suitable lesions determined to originate from the submucosa or more superficial layers using EUS can be treated using pEMR as it shortens the operational and recovery time, reduces hospitalisation costs, and achieves an R0 resection rate similar to ESD.

AbstractThe Woven EndoBridge (WEB) device is primarily used for treating wide-neck intracranial bifurcation aneurysms under 10 mm. Limited data exists on its efficacy for large aneurysms. We aim to assess angiographic and clinical outcomes of the WEB device in treating large versus small aneurysms. We conducted a retrospective review of the WorldWide WEB Consortium database, from 2011 to 2022, across 30 academic institutions globally. Propensity score matching (PSM) was employed to compare small and large aneurysms on baseline characteristics. A total of 898 patients were included. There was no significant difference observed in clinical presentations, smoking status, pretreatment mRS, presence of multiple aneurysms, bifurcation location, or prior treatment between the two groups. After PSM, 302 matched pairs showed significantly lower last follow-up adequate occlusion rates (81% vs 90%, p = 0.006) and higher retreatment rates (12% vs 3.6%, p < 0.001) in the large aneurysm group. These findings may inform treatment decisions and patient counseling. Future studies are needed to further explore this area.
Pedagogical infrastructures in multidisciplinary technology education

Published: July 2024

AbstractIn multidisciplinary technology education, teachers work together to support pupils in designing with technology. The different forms of support are based on establishing pedagogical infrastructures for pupils’ learning of technology. Although previous studies have identified the main forms of pedagogical infrastructure, how they can be leveraged in collaborative technology education remains elusive. This study adopts the perspective of teaching teams in exploring the kinds of pedagogical infrastructures involved in the collaborative planning and implementation of support for learning by collaborative designing (LCD). The data consist of semi-structured interviews with 11 technology education teaching teams. The participants were 21 experienced in-service teachers who worked in primary, secondary, and general upper secondary schools. A multiple case study approach was applied to identify the differences between the teaching teams in the planning and implementation phases. The data were analyzed following the principles of qualitative content analysis. The findings revealed that the application of pedagogical infrastructures varied during the teaching teams’ process of collaboration. In the planning phase, support was mainly based on establishing material-technological infrastructures. In the implementation phase, teachers often leveraged scaffolding and epistemological infrastructures. Pedagogical infrastructures were mostly targeted for the early stages of the LCD process, as well as in the stage of experimenting and testing design ideas.
What does it mean for a duty to be directed in joint action?
Authors: Löhr Guido 
Published: July 2024

AbstractIt is often stated that joint actions are linked to so-called directed duties. It is not just that we should “do our part” in a joint action simply because it is the right thing to do or because it is in our best interest. Instead, we “owe” it to the other participants. Despite its prima facie plausibility, this claim is not well understood. Is it true that duties in joint action are directed? Which notion of directedness is relevant to understanding the normativity of joint action? I first argue that we can characterize the notion of directed duties in joint action in terms of a network of inferentially related normative relations and practices. I apply this analysis to show that duties in joint action are directed. This analysis supports the view that the normativity in joint action is special as it involves what Stephen Darwall calls “individual authority” without entailing “representative authority”. A perhaps surprising conclusion derived from this account is that actions in joint action are owed to everyone involved in the group equally. This supports Margaret Gilbert’s joint commitment account of joint intention.
Time traveler confirms five minute hypothesis!
Authors: Sorensen Roy 
Published: July 2024

AbstractConclusion: What matters for any norm is personal time rather than time. Personal time is a time-like relation (roughly, the time measured by your wristwatch) that knits together scattered temporal parts so that they conform to familiar patterns. David Lewis introduced personal time as an interpretive fiction that allows readers to consistently read fictions about time travelers. Inadvertently, Lewis thereby introduced a metric for all value (including prudence, morality, and aesthetics). Premise: The application of any norm requires personal time rather than time. This principle of reasoning is illustrated by recent debate about Bertrand Russell’s 5 minute hypothesis. This skeptical hypothesis would be undercut if one needs more than 5 minutes to reason about it. But what reasoners actually require is personal time. Once its priority over time is established for the norms governing reasoning, all remaining norms synchronize to personal time. Re-writing diachronic epistemology in Lewis’ atemporal vocabulary salvages much of what is literally true – and exposes the primacy of causation.
Decoding high mobility group A2 protein expression regulation and implications in human cancers
Authors: Khazem Farah , Zetoune Almoutassem Billah 
Published: July 2024

AbstractHigh Mobility Group A2 (HMGA2) oncofetal proteins are a distinct category of Transcription Factors (TFs) known as “architectural factors” due to their lack of direct transcriptional activity. Instead, they modulate the three-dimensional structure of chromatin by binding to AT-rich regions in the minor grooves of DNA through their AT-hooks. This binding allows HMGA2 to interact with other proteins and different regions of DNA, thereby regulating the expression of numerous genes involved in carcinogenesis. Consequently, multiple mechanisms exist to finely control HMGA2 protein expression at various transcriptional levels, ensuring precise concentration adjustments to maintain cellular homeostasis. During embryonic development, HMGA2 protein is highly expressed but becomes absent in adult tissues. However, recent studies have revealed its re-elevation in various cancer types. Extensive research has demonstrated the involvement of HMGA2 protein in carcinogenesis at multiple levels. It intervenes in crucial processes such as cell cycle regulation, apoptosis, angiogenesis, epithelial-to-mesenchymal transition, cancer cell stemness, and DNA damage repair mechanisms, ultimately promoting cancer cell survival. This comprehensive review provides insights into the HMGA2 protein, spanning from the genetic regulation to functional protein behavior. It highlights the significant mechanisms governing HMGA2 gene expression and elucidates the molecular roles of HMGA2 in the carcinogenesis process.

Strategic assessment of groundwater potential zones: a hybrid geospatial approach
Authors: Nazaripour Hamid , Sedaghat Mahdi , Shafaie Vahid , Movahedi Rad Majid 
Published: July 2024

AbstractGroundwater aquifers constitute the primary water supply for populations in arid regions, exemplified by the Goharkooh Plain in Iran's driest drainage basin, where conditions of high evapotranspiration and low precipitation prevail. With the escalating demand for water resources, driven mainly by agricultural expansion, the strategic management of groundwater assets has become increasingly critical. This study focuses on delineating groundwater potential zones (GWPZs) through an integrated approach combining multi-criteria decision analysis and geospatial tools. Based on an extensive literature review, nine thematic layers were selected and developed: lithology, geology, drainage density, slope gradient, elevation, vegetation cover, lineament density, land use, and precipitation. These criteria were initially weighted using the analytical hierarchical process (AHP) and subsequently integrated via weighted overlay analysis. In this research, the strategic selection of thematic layers for assessing groundwater potential in arid regions has been identified as an innovative approach that could significantly advance studies in similar settings. The analysis revealed that approximately 60% of the study area, primarily in the southwestern parts, exhibited moderate to very high groundwater potential. This potential is primarily attributed to the presence of alluvial deposits, low drainage density, and favorable slope and elevation conditions. Applying the receiver operating characteristic (ROC) curve yields an area under the curve (AUC) of 81.5%, indicating a relatively high level of predictive accuracy. These findings demonstrate the efficacy of this integrated approach, suggesting its broader applicability in regions with analogous groundwater challenges and management needs.

Published: July 2024

AbstractIn this study, the effects of Gr and B4C filler materials on drilling performance, mechanical, and tribological behaviors of glass fiber-reinforced epoxy composites were experimentally investigated. Glass fiber-reinforced composite materials filled with B4C and Gr at different weight ratios (5%, 10%, and 15%) were manufactured using hand lay-up method. The produced composite materials underwent various tests, including mechanical tests (tensile and flexural tests), tribological tests (wear behavior), and drilling tests under different parameters. Additionally, SEM images of the worn and fractured surfaces were examined. The addition of both B4C and Gr fillers adversely affected the mechanical properties of glass fiber-reinforced composites. It was observed that tensile and flexural strengths decreased with increasing filler ratios. However, the addition of B4C and Gr fillers enhanced the wear resistance of glass fiber-reinforced composites. It was revealed that in drilling operations, as the feed rate increased, the thrust forces increased, while the cutting speed increased, the thrust forces decreased. It was determined that delamination values in glass fiber reinforced composites decreased as the feed rate increase, while delamination values increased as the cutting speed increased. Generally, the thrust forces, vibration, delamination, and moment values obtained during the drilling of B4C-filled glass fiber composites were found to be higher compared to Gr-filled glass fiber composites.
Comparative analysis of seismic isolation effects under three-way seismic actions for suspension core-tube structure and frame core-tube structure
Authors: Li Hui , Liu Dewen , Guo Zhongfa , Huo Yiran , Luo Xiaoxuan , Lei Min 
Published: July 2024

AbstractIn this paper, the suspension core-tube structure and frame core-tube structure are taken as the research objects, and the modal analysis of them and their basic seismic isolation structures are carried out firstly to explore the self-vibration characteristics and seismic isolation effect of the structures. Secondly, the nonlinear time-history analysis of the four structures under the action of rare earthquakes in the X, Y, and Z directions is carried out, and their inter-story drift angles, inter-story shear forces, base shear forces, maximum accelerations at the apex of the core-tube, and cantilever beam stresses are analyzed comparatively. Finally, the displacements and loads of the energy dissipators, the maximum horizontal displacements and tensile and compressive stresses of the seismic isolation bearings are analyzed to evaluate the performance of both of them under rare earthquakes. The results show that the suspension core-tube structure and the frame core-tube structure with base seismic isolation bearings can provide good control of their inter-story drift angles and internal forces, etc. The suspension core-tube structure is superior to the frame core-tube structure in controlling the maximum acceleration at the apex of the core tube response.
How Do Perceived Instructors’ Mindset Beliefs Influence STEM Students’ Belonging Uncertainty and Dropout Intentions?
Authors: Höhne Elisabeth , Lotz Christin , Deiglmayr Anne , Zander Lysann 
Published: July 2024

Abstract: We examined how undergraduate STEM students’ ( N = 389) perceptions of their instructors’ beliefs that intelligence is malleable ( growth mindsets) or unchangeable ( fixed mindsets) influence their uncertainty about belonging and, in turn, their dropout intentions. Taking an intersectional research perspective, we focused on students’ gender and immigrant background to better understand the distinct and combined impact of these social categories on students’ academic experiences. Our results show that male students who perceived their instructors to hold more fixed mindsets reported fewer dropout intentions. In contrast, female students’ dropout intentions were unaffected by their perceived instructors’ mindset beliefs. Belonging uncertainty predicted students’ dropout intentions regardless of their gender and immigrant background, but did not serve as a mediator in the relationship between perceived instructors’ mindset beliefs and dropout intentions. Overall, our findings suggest the predominance of students’ gender in the examined context rather than definitive evidence of intersectional effects with their immigrant background.
Simultaneous Multiscale 4DEnVar With Scale Dependent Localization (SDL) in Hurricane Analysis and Forecast System (HAFS)
Authors: Lu Xu , Wang Xuguang 
Published: July 2024

AbstractThis study presents the implementation and evaluation of scale‐dependent localization (SDL) in the hurricane analysis and forecast system 4D Ensemble Variational (4DEnVar) Data Assimilation (DA) system. The SDL capability is compared with the traditional Single‐Scale Localization (SSL) method to assess its benefits and necessity for hurricane prediction. The experiments focus on Hurricane Laura (2020) and involve single observation experiments as well as real observation DA cycling experiments. The results indicate that the SDL experiment, which incorporates the Fast Almost Gaussian Filtering approach for scale decomposition, consistently outperforms the corresponding SSL configurations in almost all aspects. Further diagnostics show that due to its multiscale nature, the SDL approach demonstrates better track prediction over small‐scale SSL due to improved environmental analysis and better analyzed vortex position and structure, and superior intensity prediction during the rapid intensification over both the large‐scale SSL and the small‐scale SSL owing to enhanced inner‐core thermodynamic analysis.

Published: July 2024

AbstractBristlecone pine (Pinus longaeva) (PILO) trees exhibit exceptional longevity. Their tree‐ring width (TRW) series offer valuable insights into climatic variability. Maximum latewood density (MXD) typically correlates better with temperature variations than TRW, yet PILO MXD records are non‐existent due to methodological challenges related to tree‐ring structure. Here, we used an X‐ray Computed Tomography (X‐ray CT) toolchain on 51 PILO cores from the California White Mountains to build a chronology that correlates significantly (r = 0.66, p < 0.01) with warm‐season (March‐September) temperature over a large spatial extent. This led to the first X‐ray CT‐based temperature reconstruction (1625–2005 CE). Good reconstruction skill (RE = 0.51, CE = 0.32) shows that extending MXD records across the full length of the PILO archive could yield a robust warm‐season temperature proxy for the American Southwest over millennia. This breakthrough opens avenues for measuring MXD in other challenging conifers, increasing our understanding of past climate further, particularly in lower latitudes.
Vertically Resolved Analysis of the Madden‐Julian Oscillation Highlights the Role of Convective Transport of Moist Static Energy
Authors: Yang Da , Yao Lin , Hannah Walter 
Published: July 2024

AbstractWe simulate the Madden‐Julian oscillation (MJO) over an aquaplanet with uniform surface temperature using the multiscale modeling framework (MMF) configuration of the Energy Exascale Earth System Model (E3SM‐MMF). The model produces MJO‐like features that have a similar spatial structure and propagation behavior to the observed MJO. To explore the processes involved in the propagation and maintenance of these MJO‐like features, we perform a vertically resolved moist static energy (MSE) analysis for the MJO (Yao et al., 2022, https://doi.org/10.1175/jas‐d‐20‐0254.1). Unlike the column‐integrated MSE analysis, our method emphasizes the local production of MSE variance and quantifies how individual physical processes amplify and propagate the MJO's characteristic vertical structure. We find that radiation, convection, and boundary layer (BL) processes all contribute to maintaining the MJO, balanced by the large‐scale MSE transport. Furthermore, large‐scale dynamics, convection, and BL processes all contribute to the propagation of the MJO, while radiation slows the propagation. Additionally, we perform mechanism‐denial experiments to examine the role of radiation and associated feedbacks in simulating the MJO. We find that the MJO can still self‐emerge and maintain its characteristic structures without radiative feedbacks. This study highlights the role of convective MSE transport in the MJO dynamics, which was overlooked in the column‐integrated MSE analysis.
