Published: October 2024

AbstractIn this work, CFO/MWCNTs/PVDF and BFO/MWCNTs/PVDF composites are prepared and the comparative analysis of electrical properties and electromagnetic interference (EMI) shielding performance of both type of composites are investigated. The dielectric and conductivity characteristics are observed with varying ferrite concentration, frequency, and temperature. Ferroelectric properties are also obtained at 6 kV/cm field and EMI shielding behavior is observed in 8–12 GHz frequency range. Results exhibited that the studied properties of the composite enhances with increasing ferrite concentration that attributed to increased amount of magnetic nanoparticles. Cobalt ferrite (CFO) filled polyvinylidene fluoride (PVDF) composite is showing better properties as compared to barium ferrite (BFO) filled PVDF composites. The mechanism involve for this behavior is discussed herein.
Perspective on Dual‐Tower Concentrated Solar Power Plants
Authors: Boretti Alberto 
Published: October 2024

ABSTRACTThis paper presents a comprehensive analysis of dual‐tower concentrated solar power (CSP) plants, highlighting their key technical advantages, including improved efficiency and enhanced heat distribution. The novel dual‐tower design, implemented at Guazhou, Gansu Province by Three Gorges Renewables, significantly enhances optical efficiency and reduces spillage losses compared to traditional single‐tower systems. Utilizing molten salts or particle receivers, the dual‐tower configuration offers a more efficient thermal management approach. A comparative analysis of various designs underscores the trade‐offs between increased efficiency and capital costs. The paper also discusses the economic and environmental benefits, technical challenges, and future research directions associated with dual‐tower systems, providing valuable insights into their potential to advance solar thermal technology.

Published: October 2024

AbstractBehavioral inflexibility (BI) refers to the rigid and inflexible patterns of behaviors that are a core aspect of autism. Few studies have investigated BI in autism separately from other restricted and repetitive behaviors (RRBs). The present study used a relatively new measure, the behavioral inflexibility scale (BIS; Lecavalier, L., Bodfish, J., Harrop, C., Whitten, A., Jones, D., Pritchett, J., Faldowski, R., & Boyd, B. (2020). Autism Research, 13(3), 489–499), to examine the relationship of BI and variables that are both core symptoms in autism as well as symptoms associated with cooccurring mental health conditions, atypical sensory experiences, and adaptive functioning in a sample of 87 children with autism. Additionally, we aimed to understand how these relationships may be related to autistic individuals' verbal status: minimally verbal (MV) or verbal. Results revealed that anxiety, attention deficit/hyperactive, depressive, oppositional defiance problems, and sensory differences were all significantly correlated with BI in the MV group. In contrast, only anxiety, depressive, and oppositional defiance problems were significantly correlated with BI in the verbal group. Linear regression analyses showed that oppositional defiance problems and atypical sensory experiences explained a significant proportion of the variance of BI in the MV group, whereas only depressive problems were significant in the verbal group after accounting for other mental health conditions. Overall, our findings demonstrate that multiple aspects of psychopathology are significantly related to BI and can have broader implications for interventions and mental health care in autistic children.
Pursuing systemic improvement through heterarchical school systems: A case of educational resources
Authors: Gripton Catherine , Noyes Andrew 
Published: October 2024

AbstractEngland's schooling landscape is being remodelled and the move from hierarchical to heterarchical modes of governance has implications for systemic change strategies. Balancing local and networked autonomy with centralising policies complexifies choices for schools, creating tensions that this article explores through the context of curriculum resourcing policies. In particular, we consider the contemporary case of mathematics textbook schemes in England's heterarchical school system, comparing them with an earlier resource‐driven systemic change programme—the National Numeracy Strategy—which was implemented in a more hierarchical governance system. Drawing on key ideas from implementation science and data from a Wellcome‐funded study of primary teacher professional learning in mathematics in England, we exemplify the challenges of implementing centralised improvement policies in a nominally schools‐led, self‐improving, heterarchical education system. Each of the 19 participating schools had evolved a bespoke curriculum, and these hybridised ‘mashups’ of different resources were enacted with varying degrees of fidelity by teachers. We discuss the implications of this comparative case for systemic improvement, both in the use of educational resources and for policy implementation more generally.

ABSTRACTA new method has been developed to improve the detection of norovirus (NoV) in complex fecal samples using nanocatalyst‐based immunoassays. The method involves using multifunctional trimetallic nanoparticles, known as Ag@Fe3O4@Au NPs. These nanoparticles consist of a core of silver (Ag) and a shell of iron oxide (Fe3O4) decorated with isolated gold nanoparticles (Au NPs). The nanoparticles have enhanced catalytic activity, making them an ideal nanocatalyst for reducing 4‐nitrophenol (4‐NP, yellow) to 4‐aminophenol (4‐AP, colorless). The developed Ag@Fe3O4@Au NPs‐based immunoassay achieved a limit of detection (LOD) of 1.9 pg/mL for norovirus‐like particles (NoV‐LP) and 6.97 RNA copy number/mL for fecal NoV. In fecal sample analysis for NoV, a heat treatment at 65°C was necessary to prevent degradation of the target protein, ensuring sensitive detection. This work successfully combined multifunctional nanocatalysts for advanced immunoassays, which could contribute to developing nano‐biosensing platforms.

Published: October 2024

AbstractThis study explores the impact of a CEO's educational background from a top university on reducing corporate ESG risk and the potential moderating role of CEO gender. Using the QS World University Rankings (QS WUR) to define reputable universities, the research focuses on companies in ASEAN (Association of Southeast Asian Nations) countries, known for elevated ESG risks. Through Ordinary Least Squares (OLS) regression analysis, the results show that CEOs educated at top universities reduce ESG risk, while CEO gender does not moderate this relationship. The findings represent the importance of reputable universities as habitus to support the globalization of business and responsible management education, regardless the gender. The results also highlight the influence of educational background on corporate ESG performance, with significant implications for corporate strategy and CEO appointments.
Joint inference for telemetry and spatial survey data
Authors: Blackwell Paul G. , Matthiopoulos Jason 
Published: October 2024

AbstractData integration, the joint statistical analysis of data from different observation platforms, is pivotal for data‐hungry disciplines such as spatial ecology. Pooled data types obtained from the same underlying process, analyzed jointly, can improve both precision and accuracy in models of species distributions and species–habitat associations. However, the integration of telemetry and spatial survey data has proved elusive because of the fundamentally different analytical approaches required by these two data types. Here, “spatial survey” denotes a survey that records spatial locations and has no temporal structure, for example, line or point transects but not capture–recapture or telemetry. Step selection functions (SSFs—the canonical framework for telemetry) and habitat selection functions (HSFs—the default approach to spatial surveys) differ in not only their specifications but also their results. By imposing the constraint that microscopic mechanisms (animal movement) must correctly scale up to macroscopic emergence (population distributions), a relationship can be written between SSFs and HSFs, leading to a joint likelihood using both datasets. We implement this approach using maximum likelihood, explore its estimation precision by systematic simulation, and seek to derive broad guidelines for effort allocation in the field. We find that complementarities in spatial coverage and resolution between telemetry and survey data often lead to marked inferential improvements in joint analyses over those using either data type alone. The optimal allocation of effort between the two methods (or the choice between them, if only one can be selected) depends on the overall effort expended and the pattern of environmental heterogeneity. Examining inferential performance over a broad range of scenarios for the relative cost between the two methods, we find that integrated analysis usually offers higher precision. Our methodological work shows how to integrate the analysis of telemetry and spatial survey data under a novel joint likelihood function, using traditional computational methods. Our simulation experiments suggest that even when the relative costs of the two methods favor the deployment of one field approach over another, their joint use is broadly preferable. Therefore, joint analysis of the two key methods used in spatial ecology is not only possible but also computationally efficient and statistically more powerful.

AbstractTin‐halide perovskite solar cells (THPSCs), while offering low toxicity and high theoretical power conversion efficiency, suffer from inferior device performance compared to lead‐based counterparts. The primary limitations arise from challenges in fabricating high‐quality perovskite films and mitigating the oxidation of Sn2+ ions, which leads to severe non‐radiative voltage losses. To address these issues, we incorporate the rare‐earth element erbium chloride (ErCl3) into PEA0.15FA0.70EA0.15SnI2.70Br0.30 perovskite to effectively control the nucleation and crystal growth, significantly influencing the morphology of the perovskite films. As a result, the ErCl3‐processed THPSC exhibits an impressive open‐circuit voltage (VOC) of 0.83 V and power conversion efficiency (PCE) of 14.0% with the superior light and air stability, compared to the control device (VOC = 0.77 V and PCE = 12.8%). This ErCl3‐strategy provides a feasible solution for high‐performance THPSCs by regulating nucleation/crystallization kinetics and mitigating excessive crystal defects during the preparation process of lead‐free perovskites.image

AbstractObjectiveN‐methyl‐D‐aspartate receptors are glutamate‐gated ion channels that play a crucial role in brain function. Numerous inherited or de novo variants in the GRIN2A gene, encoding the GluN2A subunit of the receptor, have been identified in patients with epilepsy. In addition, it is worth noting that GRIN2A variants exhibit a strong correlation with epilepsy‐aphasia syndromes, a group of age‐dependent epileptic, cognitive, and language disorders with a characteristic electroencephalographic pattern.MethodsWhole exome sequencing was conducted in enrolled patients with epilepsy‐aphasia syndromes, and GRIN2A variants were screened. The conservation of substituted residues, conformational changes of mutant subunits, and in silico predictions of pathogenicity were thoroughly assessed in our study. Functional alterations of the variants were examined using whole‐cell voltage‐clamp current recordings while the relative surface expression levels of subunit proteins were assessed via immunofluorescence assays. A summary of previously published GRIN2A missense variants was conducted to investigate the genotypic‐phenotypic‐functional correlations.ResultsTwo missense GRIN2A variants (c. 2482A >G/p. M828V, c. 2627 T >C/p. I876T) were identified, which are located in the transmembrane helix M4 and C‐terminus domain of the GluN2A subunit, respectively. Both variants exhibited reduced current density of NMDARs and surface/total expression levels of GluN2A subunits, while M828V showed a decreased extent of desensitization as well. A further summary of the previously reported GRIN2A variants demonstrated that more variable phenotypes were observed for variants situated in the C‐terminus domain or those with loss‐of‐function effects.SignificanceOur study expands the phenotypic and functional range of GRIN2A‐related disorders. In order to optimally establish the domain‐function‐phenotype correlations in GRIN2A variants, it is imperative to gather a more extensive set of clinical and functional data.Plain Language SummaryThis study has identified two genetic variants of the GRIN2A gene in patients with epilepsy‐aphasia syndrome. We assess the variants' harmfulness through a variety of functional experiments, including evaluating the expression level of the mutated protein and the resulting changes in electrophysiological activities. Also, we reviewed previously published papers about GRIN2A variants in epilepsy to learn more about the correlations between their locations, functional changes, and clinical manifestations.
GPRASP protein deficiency triggers lymphoproliferative disease by affecting B‐cell differentiation

AbstractGprasp1 and Gprasp2 encode proteins that control the stability and cellular trafficking of CXCR4, a master regulator of hematopoiesis whose dynamic regulation is required for appropriate trafficking of B‐cells in the germinal center (GC). Here, we report that Gprasp1 and Gprasp2‐deficient B‐cells accumulate in the GC and show transcriptional abnormalities, affecting the mechanisms controlling Aicda expression and exposing them to excessive somatic hypermutation. Consequently, about 30% of mice transplanted with Gprasp‐deficient hematopoietic stem and progenitor cells developed a biologically aggressive and fatal B‐cell hyperproliferative disease by 20–50 weeks posttransplant. Histological and molecular profiling reveal that Gprasp1‐ and Gprasp2‐deficient neoplasms morphologically resemble human high‐grade B‐cell lymphomas of germinal center origin with shared morphologic features of both Burkitt Lymphoma (BL) and diffuse large B‐cell lymphoma (DLBCL), and molecular features consistent with DLBCL, as well as elevated mutational burden and heterogenous transcriptional and mutational signature. Thus, reduced Gprasp1 and Gprasp2 gene expression perturbs B‐cell maturation and increases the risk of B‐cell neoplasms of germinal center origin. As this model recapitulates the essential features of the heterogenous group of human hematopoietic malignancies, it could be a powerful tool to interrogate the mechanisms of lymphomagenesis for these cancers.

Published: October 2024

AbstractBackground and AimsGait initiation (GI) in individuals with chronic ankle instability (CAI) has shown differences in the center of pressure (COP) and muscular measures compared to healthy controls. Some studies reported that these alterations appeared when GI was with the affected leg, while others indicated that they occurred when GI was with the non‐affected leg. This systematic review aimed to understand kinetic and muscular differences between individuals with CAI, healthy controls, and the affected and non‐affected legs of individuals with CAI.MethodsPubMed, Science Direct, Web of Science, Google Scholar, and Scopus databases (1990–2023) were searched using the Population, Exposure, Comparator, and Outcome measure. The PRISMA guidelines were followed. The outcome measures were the peak and rate of COP displacement in the medial‐lateral and anterior‐posterior directions, and resultant plane during phases 1, 2, and 3 of COP trace during GI and the duration of each phase. The other measures included the onset time of the tibialis anterior and soleus muscle activity between individuals with CAI, healthy controls, and the affected and non‐affected legs of the individuals with CAI. The studies' quality assessment was conducted based on the Strengthening the Reporting of Observational Studies in Epidemiology checklist.ResultsFive studies were included in the final evaluation. The results of included studies showed, individuals with CAI spent less time during phases 1 and 2, as well as a shorter peak of COP displacement in the lateral direction during phase 1 compared to healthy controls, regardless of whether the GI was with the affected or non‐affected leg.ConclusionIndividuals with CAI have probably adopted a strategy involving adjusting the peak of COP displacement to manage internal sway while in a single‐leg stance. Overall, there was no comprehensive conclusion about differences between the two legs in individuals with CAI.

ABSTRACTBackground and AimsSleep issues pose a significant burden to public health and well‐being in Saudi Arabia. However, research evidence on sleep health among psychiatry physicians in this territory is limited. Therefore, to bridge the research gap, this study was designed to assess the prevalence and predictors of poor sleep quality among psychiatry physicians in the country.MethodsThis cross‐sectional study included 554 psychiatry physicians in Saudi Arabia from March to August 2023. Data were collected via online through a structured questionnaire (Google survey form). Sleep quality, the outcome variable of our study, was evaluated with the Pittsburgh Sleep Quality Index (PSQI; 19 items). Independent variables included sociodemographic and behavioral characteristics, sleep habits, major depression (assessed with Patient Health Questionnaire‐9), and anxiety (measured with Generalized Anxiety Disorder‐7) symptoms. Binary logistic regression analysis was performed to identify the correlates of poor sleep quality.ResultsBased on the PSQI, 61.3% of the study participants had poor‐quality sleep (age range: 24–56 years, male: 48.0%). The adjusted model revealed that male participants (AOR = 2.80, 95% CI = 1.70–4.61) and those who had on‐call duties ≥ 2 times per week (for three/four per week: AOR = 3.41, 95% CI = 1.89–6.14) were at higher risk of developing poor sleep quality compared to their respective counterparts. Participants with depressive symptoms (AOR = 3.46, 95% CI = 1.60–7.48) and smoking habits (AOR = 3.47, 95% CI = 1.32–9.08) had higher odds of developing poor sleep quality than their counterparts. Moreover, participants who always used their smartphone/laptop before going to bed were more likely to have poor sleep quality than those who never used such (AOR = 3.15, 95% CI = 1.31–7.60).ConclusionPoor sleep quality is extremely prominent among psychiatry physicians in Saudi Arabia. Male sex, higher on‐call duty, smoking habits, depression, and smartphone/laptop use before bedtime were significantly associated with poor sleep quality. These findings emphasize the need for sleep‐health promotion interventions for Saudi psychiatry physicians.

AbstractPurpose/objectivesThis prospective crossover preclinical trial aimed to evaluate the learning curve of dental students in successfully administering intraligamentary anesthesia (ILA) using three different syringe systems.MethodsDental students performed ILA using three devices in two separate sessions, each targeting mandibular and/or maxillary premolars. The devices included two manual systems (pistol‐type and lever‐based) and one computer‐controlled local anesthetic delivery system (CCLAD). The primary research parameter was the success rate of anesthesia, defined as the percentage of successful ILA administrations confirmed by a negative response to a cold test. Secondary parameters included pain experienced during needle penetration and injection, students' self‐reported levels of mental tension and handling of the syringes, and any potential side effects.ResultsA total of 110 students performed ILA on 599 teeth during the study period. When comparing the CCLAD system to the manual syringes, the CCLAD system exhibited a significantly higher overall success rate in the first session (92.5% vs. 77.4%; p < 0.001), potentially due to its precise control of anesthetic flow and pressure, which likely facilitated more effective anesthetic delivery. However, when examining the individual manual techniques, no significant difference was found between the pistol‐type manual and the CCLAD system (p = 0.66). All techniques' success rate increased from the first to the second session (80.4% vs. 86.9%; p = 0.0357). Additionally, penetration pain demonstrated a significant decrease across all techniques (p < 0.01). Notably, students' anxiety levels decreased, and self‐assurance increased significantly over the sessions. Undesired reversible side effects were documented in 10.9% of cases.ConclusionThese findings suggest that repeated practice of ILA, particularly with different syringe systems, enhances anesthetic success and psychological readiness for patient interaction. Additional training sessions may further improve proficiency.
