N
= 4 SYM theory. The effective action of the probe brane is proportional to the logarithmically divergent volume of AdS3 and may thus be interpreted as computing conformal anomaly of supersymmetric S2 defect. The classical action scales as N. We compute the 1-loop correction to it due to quantum fluctuations of the D3 brane world-volume fields and compare the result to an earlier suggested expression for the defect anomaly. We also perform a similar analysis of a $$ \frac{1}{2} $$

-BPS M5 brane probe solution in AdS7× S4 with the world-volume geometry of AdS5× S1 that represents a dimension 4 defect in the boundary (2,0) 6d theory. Here the classical M5 brane action computes the leading order N2 term in a-anomaly of the supersymmetric S4 defect. We perform a detailed computation of the 1-loop correction to the M5 brane effective action and thus provide a prediction for the subleading constant in the S4 defect a-anomaly coefficient.
Algebraic characterizations of homeomorphisms between algebraic varieties

Published: July 2024

Abstract
We address the question of finding algebraic properties that are respectively equivalent, for a morphism between algebraic varieties over an algebraically closed field of characteristic zero, to be a homeomorphism for the Zariski topology and for a strong topology that we introduce. Our answers involve a study of seminormalization and saturation for morphisms between algebraic varieties, together with an interpretation in terms of continuous rational functions on the closed points of an algebraic variety. The continuity refers to the strong topology which is the usual Euclidean topology in the complex case and which comes from the theory of real closed fields otherwise.

Abstract
Purpose
The contribution of androgen receptors (AR) on bladder cancer has been demonstrated in pre-clinical studies, however in clinical studies, only the canonical AR (AR-FL) protein was measured by immunohistochemistry and conflicting results were obtained. To get better insight into the alterations of AR signalling, we used western blotting (WB) method and simultaneously measured both mRNA and protein levels of AR-FL and AR-V7.

Methods
23 naive non-muscle invasive bladder cancer patients and 12 healthy individuals were included. AR-FL protein, AR-FL mRNA, AR-V7 protein and AR-V7 mRNA levels were quantitatively measured by WB and qRT-PCR.

Results
While AR-FL protein and AR-V7 mRNA were significantly higher in bladder cancer, AR-FL mRNA and AR-V7 protein were lower. AR-V7 mRNA level was higher in patients with tumour size over 3 cm and AR-FL protein was higher in single tumours (p < 0,005). The small sampling size and the inclusion of only male participants were the main limitations.

Conclusions
The increase of AR-FL protein in bladder cancer supports the contribution of the AR pathway in bladder cancer. The presence of high AR-FL protein despite low mRNA levels may be due to a disruption in post-transcriptional regulatory mechanisms. AR-V7 was demonstrated for the first time in bladder tissue and found significantly different in bladder cancer tissues. Our study reached new and valuable findings and will shed light on the studies that aim to clarify the role of the AR pathway in bladder cancer.

Published: July 2024

Abstract
Introduction
The dynamic hip screw (DHS) and cannulated compression screws (CCS) have been the two implants most frequently employed for the fixation of femoral neck fractures. The objective of this study is to compare clinical and radiographic outcomes between patients treated with the FNS and those treated with CCS.

Material and methods
We conducted a retrospective analysis of a consecutive series of femoral neck fractures treated with FNS or CCS between May 2019 and June 2022. The study included 144 patients who met the inclusion criteria. Collected data encompassed age, sex, Garden fracture classification, Pauwels classification, duration of surgery, length of hospital stays, Harris Hip Score (HHS), complications, and injured side.

Results
The FNS group comprised 70 patients, while the CCS group consisted of 74 patients. The operation time was 43.6 ± 12.09 min for the FNS group and 56.47 ± 22.42 min for the CCS group. At the end of the follow-up, the mean HHS was 87.07 ± 11.77 for the FNS group and 76.20 ± 13.64 for the CCS group. The mean reduction in hemoglobin levels from pre- to post-surgery was 1.05 mg/dl in the FNS group and 0.87 mg/dl in the CCS group. The reintervention rate was 8.1% for the CCS group and 2.85% for the FNS group.

Conclusion
The FNS does not demonstrate superiority over CCS regarding femoral neck shortening, complication rate, and reduction in hemoglobin levels. However, FNS does appear superior to CCS in terms HHS, operation time, and reoperation rate.
The values of schools: an analysis of vision statements
Authors: Daniel Ella , Arieli Sharon , Akerman Liat 
Published: July 2024

AbstractSchool vision statements articulate an aspired future state for the school, highlighting its ideals, purpose, and unique aspects to direct behavior and promote motivation and commitment among stakeholders. This paper investigates vision statements of schools as artifacts expressing the values emphasized by schools, drawing on organizational literature that shows the role of central organizational artifacts in conveying the values important to the organization. Using a comprehensive sample of elementary schools across all districts in Israel (N = 99), we built on Schwartz’s values theory to identify values and analyze expressed values. We employed a mixed methods approach, combining qualitative and quantitative methods to analyze these values. First, we analyzed the content of vision statements to investigate how values were manifested. Then, we investigated the values hierarchy reflected in the vision statements, and compared sectors to identify the impact of the broader social context. Our analysis revealed variation in values expression: as expected, self-direction and benevolence emerged as the most prevalent values in school vision statements; power and hedonism were less salient. Comparison of vision statements from public and public-religious schools, as well as across schools with varying socioeconomic status (SES), revealed differences in universalism values. Public schools and those with higher SES placed greater importance on universalism values compared to public-religious schools. Additionally, tradition values were less prominent in public schools but were the second most significant values in public-religious schools. We discuss the results within the framework of values theory and educational policy.
Definition and validation of a valley amplification factor for seismic linear response of 2D homogeneous alluvial basins
Authors: Alleanza Giorgio Andrea , d’Onofrio Anna , Silvestri Francesco 
Published: July 2024

AbstractThe paper presents findings from a parametric study analysing geometric (e.g., shape ratio, edge inclination) and stratigraphic factors (e.g. impedance ratio) influencing ground motion in trapezoidal valleys. The study involved 2160 visco-elastic analyses, considering 180 2D models with diverse shapes and soil properties, undergoing 12 synthetic input motions. Analyses results showed that the motion at the valley centre increases with both shape and impedance ratios, while it is independent of the edge slope; on the other hand, the maximum amplification at the edges depends on their inclination and on the impedance ratio, while it is independent of the valley shape. The position and size of the zone of maximum amplification at the edges depend on all the previous parameters. A valley amplification factor (VAF) is introduced to quantify spectral acceleration increase due to 2D effects. Closed-form equations are proposed to evaluate VAF based on valley properties. The proposed VAF is then applied to predict seismic amplification in two central Italian valleys, providing results well-comparable to those obtained from 2D numerical analyses. The described approach can be easily implemented into codes of practice as a conservative design tool to estimate 2D amplification along the surface of ‘shallow valleys’ subjected to moderate seismic actions.

Published: July 2024

AbstractNanocellulose has emerged as a widely utilized building block in nanostructured materials due to its availability, sustainability, large surface area, and high stiffness and aspect ratio. The wet or dry elastoplastic properties of these materials are determined by the fibrils' stiffness, chemical properties, hemicellulose content, and the number of fibril contacts. However, the specific contributions and relative importance of each factor remain unclear. Therefore, this work was devoted to systematically comparing the material properties of gels, aerogels, and wet and dry sheets prepared from CNFs with different aspect ratios, chemical functionality, and hemicellulose content. The fibrils were prepared by chemical and mechanical processing of different pulps. By preserving the native structure as much as possible, higher aspect ratio fibrils can be obtained, which allows for the development of more mechanically robust materials. The results demonstrate that higher aspect ratios lead to more interconnected networks at a lower solids concentration, resulting in a more evenly distributed stress and longer-range stress transfer, yielding stiffer and more ductile materials. The most important finding was that the aspect ratio influences the network formation, resulting in different network topologies. The results were also compared to earlier published data and integrated into a theoretical beam-bending model for a complete elastoplastic description of the network properties, including the influence of fibril aspect ratio and chemical functionality. This information improves our understanding and description of nanofibril networks for which general models have been missing. It can be used to optimize nanofibril preparation and, hence, the resulting eco-friendly materials.
Mixing Pedagogies to Cultivate Joyful and Creative Young Writers in an Era of Standardised Writing Tests
Authors: Brosseuk Deb 
Published: July 2024

AbstractGlobal trends suggest that teaching writing focuses on a skills-based approach to preparing children for high-stakes standardised tests. In the early years, teachers are grappling with finding a better balance between preparing children for such tests and satisfying their sense of pedagogic responsibility to teach them to become joyful, creative writers. This paper explores an Australian Preparatory teacher’s teaching of writing framed by the pedagogic framework LAUNCH. Using video and audio recordings, as well as children-made artefacts, the paper considers the impact of this framework on the writing experiences of fourteen five- and six-year-old children. Basil Bernstein’s visible and invisible pedagogies provide the theoretical frame. Findings assert that a pedagogic mix allows early years teachers to teach children to be skilled and confident writers while nurturing their imaginations and creativity. This is significant given that current debates around children’s writing experiences are often tied to high-stakes, standardised test-based writing.
Ten Years of Dimensional Comparison Theory: On the Development of a Theory from Educational Psychology
Authors: Möller Jens 
Published: July 2024

AbstractDimensional comparison theory (DCT; Möller & Marsh 2013:Psychological Review, 120(3), 544–560), first formulated 10 years ago, describes individuals’ internal comparison processes applied between different areas of their lives. Dimensional comparisons explain the seemingly counterintuitive phenomenon that students’ verbal and mathematical self-concepts are almost uncorrelated, even though mathematical and verbal performances correlate highly positively: When students compare their performance in verbal and mathematical domains, dimensional comparisons lead to a contrast effect: students overestimate their ability in the intra-individually better domain and underestimate their ability in their intra-individually weaker domain, leading to near-zero correlations between the respective self-concepts.This paper describes diverse extensions of the classic DCT into a variety of predictors (especially various school subjects, beyond math and native language) and criteria (especially task value components, in addition to subject-specific self-concepts) and extensions of the applicability of the DCT as an educational psychological theory to contexts such as clinical and health psychology. Recent findings on the psychological processes that trigger, accompany, and follow dimensional comparisons are summarized, before an overview of different methods to capture dimensional comparisons is given, and further research directions are discussed.
A verified durable transactional mutex lock for persistent x86-TSO
Authors: Vafeiadi Bila Eleni , Dongol Brijesh 
Published: July 2024

AbstractThe advent of non-volatile memory technologies has spurred intensive research interest in correctness and programmability. This paper addresses both by developing and verifying a durable (aka persistent) transactional memory (TM) algorithm, $$\text {dTML}_{\text {Px86}}$$

dTML
Px86

. Correctness of $$\text {dTML}_{\text {Px86}}$$

dTML
Px86

is judged in terms of durable opacity, which ensures both failure atomicity (ensuring memory consistency after a crash) and opacity (ensuring thread safety). We assume a realistic execution model, Px86, which represents Intel’s persistent memory model and extends the Total Store Order memory model with instructions that control persistency. Our TM algorithm, $$\text {dTML}_{\text {Px86}}$$

dTML
Px86

, is an adaptation of an existing software transactional mutex lock, but with additional synchronisation mechanisms to cope with Px86. Our correctness proof is operational and comprises two distinct types of proofs: (1) proofs of invariants of $$\text {dTML}_{\text {Px86}}$$

dTML
Px86

and (2) a proof of refinement against an operational specification that guarantees durable opacity. To achieve (1), we build on recent Owicki–Gries logics for Px86, and for (2) we use a simulation-based proof technique, which, as far as we are aware, is the first application of simulation-based proofs for Px86 programs. Our entire development has been mechanised in the Isabelle/HOL proof assistant.
Temporal changes of the Oyashio water distribution east of Japan under the changing climate: development of an objective evaluation method and its application

Published: July 2024

Abstract
The Oyashio, a southern part of the western boundary current in the North Pacific subarctic gyre, carries cold and fresh seawater with abundant nutrients southward from the high-latitude, influencing regional climate in the East Asia and marine environment in the western mid-latitude North Pacific. Previously, a distribution of the Oyashio water has been evaluated by empirical temperature thresholds; for example, in spring (March–May) when the Oyashio intrudes southward into the east of Japan, the Oyashio water is defined at 100-m depth as ≤ 5 °C. However, this method is not necessarily adequate under the changing climate because upper ocean temperature may change over time due to some causes unrelated to cold water transport by the Oyashio (e.g., surface heat fluxes). In this study, we developed an objective method to evaluate the Oyashio water distribution applicable under the changing climate with a focus on a thermohaline front located at the warm- and salty-side boundary of the Oyashio water. We identified isohalines at 100-m depth best corresponding to the thermohaline front in each month and used them as the Oyashio water threshold. Using the developed method, we further investigated the springtime Oyashio water distribution east of Japan (in the North Pacific south of 43°N, 141–148°E). The area of the Oyashio water shows inter-annual variation and significant long-term decrease. It was suggested that these temporal variation and change reflect changes in a distribution of anti-cyclonic meso-scale eddies off Hokkaido, which block the southward Oyashio intrusion into the east of Japan.

Published: July 2024

AbstractIn alignment with the rallying cry of the self-advocacy movement, it is critical to center the perspectives of people with disabilities about their lived experiences. Yet, little is known about how youth with intellectual and/or developmental disabilities (IDD) engage in self-advocacy and civic engagement in special education. We conducted focus groups with 15 transition-aged youth with IDD across four states about self-advocacy and civic engagement. Youth with IDD reported engaging in self-advocacy at school, but outside of their individualized education program meetings. Parent advocacy and positive partnerships with educators promoted youth self-advocacy. Youth reported minimal involvement in civic engagement, but they had suggestions for systemic changes to special education. Implications for research and practice are discussed.
Modeling Group Discourse with Epistemic Network Analysis: Unpacking Connections, Perspectives, and Individual Contributions
Authors: Goldfarb Cohen Shai , Yanai Johnatan Verissimo , Dishon Gideon 
Published: July 2024

AbstractOperationalizing and modeling group talk has proved to be a consistent challenge in educational research. In this paper, we suggest that epistemic network analysis (ENA) could provide unique insights concerning group talk. Specifically, we use ENA to model the talk orientations put forward in the Exploratory Talk framework (Cumulative, Disputational, Exploratory). Participants (n = 60, 67% female, 33% male) were undergraduate students in an Introduction to Psychology course who took part in three 90-min collaborative online tasks. We coded student discourse according to a set of basic communicative acts reflective of the Exploratory Talk framework. Then, using ENA, we identified different groups’ patterns of discourse at the group and individual level. Presenting the epistemic networks of four purposefully chosen groups, this paper offers three key contributions to modeling and conceptualizing group dialogue: (1) illustrating how ENA could offer new ways to analyze group talk by focusing on the frequency of co-occurrence of connections between a basic set of communicate acts rather than the different communicative acts used; (2) refining the theoretical conceptualization of Exploratory Talk by distinguishing two sub-variations—other-oriented vs. self-oriented Exploratory Talk—that differ according to the depth of engagement with other perspectives; (3) examining how ENA allows unpacking diverging dynamics of individual contributions to group discourse, focusing on the role of individuals that function as “instigators” or “connectors.”
Transparent self-cleaning coating prepared from SiO2/B4C and SiO2/B4C/TiO2 for the solar cell
Authors: Koysuren Hafize Nagehan , Koysuren Ozcan 
Published: July 2024

AbstractTransparent self-cleaning coatings based on photocatalytic activity have attracted great attention in recent years owing to their promising applications in many fields, such as solar cell cover glass. This study reports a simple method to prepare transparent self-cleaning silicon dioxide (SiO2) coatings filled by boron carbide (B4C) and titanium dioxide (TiO2) nanoparticles. A sol-gel technique was used to synthesize a SiO2solution containing B4C and TiO2nanoparticles, and a dip-coating technique was followed to coat the composite solution on glass slides. The SiO2coating was successfully obtained in the presence of both semiconductor nanoparticles as confirmed by FTIR and XRD measurements. Both the photocatalytic activity and self-cleaning property of the composite coatings were evaluated by photocatalytic degradation of a model dye, methylene blue, under visible light irradiation. The SiO2coating containing both B4C and TiO2nanoparticles exhibited an improved photocatalytic activity compared to the SiO2coating including only B4C. In particular, a 46% degradation rate of the model dye methylene blue was achieved for the SiO2coating containing 15 wt% B4C and 5 wt% TiO2nanoparticles. Highly transparent composite coatings on glass slides were prepared. The SiO2coating containing both B4C and TiO2nanoparticles was found to exhibit ~8% reduction in the optical transmission of the glass slide and ~1% reduction in the efficiency of a solar cell containing the coated glass slide. These findings demonstrated that the SiO2composite coatings have potential for self-cleaning applications in removing contaminants from the glass cover of the solar cell under visible light irradiation.Graphical Abstract
