Published: December 2024

Abstract
This study explores Ultra-Orthodox Jewish women’s attitudes toward video-consultation usage in Israeli primary care settings. In-depth interviews were conducted with twenty-two women from diverse Ultra-Orthodox communities in Israel, using interpretative phenomenological analysis. Despite traditionally limited digital tool usage, participants showed readiness for video-consultations’ adoption through dedicated ‘kosher’ medical devices. Key motivations included after-hours accessibility, convenience, and privacy, while barriers involved cultural stigma and technology concerns. Healthcare organizations should develop dedicated telemedicine devices aligned with religious values, offering insights for implementing culturally sensitive services for religious minority groups.

Published: December 2024

AbstractThis qualitative case study used artifacts (e.g., youth activities), archival records (mentor logs), and individual interviews to understand 12 Black youths’ experiences of an electronic mentoring (e-mentoring) program that was designed in partnership with a local Black church to address subclinical mental and behavioral health challenges that impacted K-12 students’ academic functioning. Findings revealed participants learned how to persevere and regulate their actions to counter maladaptive thoughts, emotions, and behaviors that impacted their engagement in school when faced with academic difficulties. Participants also learned how to maintain self-confidence and view themselves in a positive light through self-affirmations and by recognizing their strengths. Finally, the youth felt valued and nurtured by their mentors, which helped facilitate the students’ engagement in the program. This study shows how youth-centered e-mentoring through community partnerships with predominantly Black churches can help Black youth access culturally responsive mental health and behavioral health support that may foster their academic success.

Abstract
Introduction
South Africa’s Department of Basic Education introduced a policy in December 2021 to protect rural school learners from sexual exploitation. Schools must report statutory rape cases involving pregnant learners under 16 years of age with partners over 16. However, rural implementation faces significant barriers, highlighting the gap between policy intent and reality.

Methods
A cyclical longitudinal ethnographic design was used to investigate the reasons for the limited implementation of the policy in rural schools. The data were collected through group discussions with 19 educators in August 2024 in the Soutpansberg North Circuit. The analysis, guided by an ethnographic content analysis framework, drew on intersectionality and social and cultural norms theories.

Results
The findings revealed that in addition to a lack of awareness of the policy and a lack of training, deep-rooted sociocultural norms hindered teachers and schools from reporting statutory rape cases. The findings also suggested interventions to improve implementation.

Conclusion
Based on the study findings, we recommend adopting a multidisciplinary approach and integrating knowledge and methodologies from various fields, such as education, psychology, and social work. Specifically, we recommend that the Department of Basic Education should raise awareness of the policy in schools and among teachers and communities; implement a confidential, standardised reporting system; and provide training to educators on handling statutory rape cases to ensure more effective implementation and achieve the intended outcomes of the policy.

Policy Implications
To bridge the gap between the statutory rape policy and effective implementation, policymakers must contextualise educational policies in terms of the realities of rural South African teachers.

AbstractCoal bursting liability refers to the mechanical property of the degree and possibility of coal burst. The bursting liability is important to evaluate coal burst in mining. In this paper, the needle penetration test was carried out to determinate the coal bursting liability, and the empirical criterion of coal bursting liability was proposed. Moreover, the machine learning method was applied to coal bursting liability determination. Through analyzing the elastic strain energy release and failure time, the residual elastic strain energy release rate index KRE was proposed to evaluate the coal bursting liability. According to the relationship between needle penetration index (NPI), KRE and the critical value of KRE, the Needle Penetration Test-based Empirical Classification Criterion (NPT-ECC) was obtained. In addition, four machine learning classification models were constructed. After training and testing of the models, Needle Penetration Test-based Machine Learning Classification Model (NPT-MLCM) was proposed. The research results show that the accuracy of NPT-ECC is 6.66% higher than that of China National Standard Comprehensive Evaluation (CNSCE) according to verification of the coal fragment ejection ratio F. Gridsearch cross validation-extreme gradient boosting (GSCV-XGBoost) has the best prediction performance among all the models, and accuracy, Macro-Precision, Macro-Recall and Macro-F1-score of which were 86.67%, 88.97%, 87.50% and 87.37%. Based on this, the Needle Penetration Test-based GSCV-XGBoost (NPT-GSCV-XGBoost) was proposed. After comparative analysis and discussion, NPT-GSCV-XGBoost is superior to NPT-ECC and CNSCE in the comprehensive prediction ability.
An asymptotically optimal two-sample instrumental variables estimation using many instruments
Authors: Kunitomo Naoto , Yuasa Ryota 
Published: December 2024

AbstractWe investigate the statistical estimation of the coefficients in a linear structural equation within a simultaneous equation system, utilizing two-sample data and a large number of instrumental variables. Specifically, we derive the asymptotic properties of the two-sample least variance ratio (2SLVR) estimator, an extension of the limited information maximum likelihood (LIML) estimator designed for one-sample contexts, in the two-sample setting with numerous instruments. It is well-documented that the one-sample two-stage least squares (TSLS) estimator and the generalized method of moments (GMM) suffer from non-negligible bias. Despite their widespread practical use, these methods often lose consistency when a large number of instruments are employed. In contrast, our findings demonstrate that the variance–covariance matrix of the limiting distribution of the 2SLVR estimator and its modifications frequently achieve the asymptotic lower bound, even when the disturbance terms deviate from a normal distribution. The results of this study hold significant potential for applications in econometrics and biometrics, particularly in contexts such as Mendelian Randomization (MR) analyses using DNA data.
Enhancement in Reliability of IEEE 802.15.4 WBAN Using Greedy Spider Monkey Algorithm
Authors: Pandey Umashankar , Chandra Saroj Kumar , Dewangan Narendra Kumar 
Published: December 2024

AbstractWireless Body Area Networks (WBANs) hold immense potential in healthcare monitoring, but ensuring reliable data transmission is crucial. While the IEEE 802.15.4 standard offers low-power operation and basic security, its Contention-Based Access (CBA) mechanism can lead to packet collisions and reduced reliability, especially in congested scenarios. This paper proposes a novel approach to enhance reliability in 802.15.4 WBANs by incorporating a Greedy Spider Monkey Optimization Algorithm (GSMA). The GSMA mimics the intelligent foraging behaviour of spider monkeys, enabling dynamic channel selection and optimal transmission scheduling. Our approach aims to minimize packet collisions by selecting channels with lower traffic based on historical data and real-time network conditions; the GSMA reduces the likelihood of collisions and data loss. Secondly, the algorithm prioritizes critical data packets based on their urgency and channel availability, ensuring the timely delivery of essential medical information. Finally, by reducing collisions and optimizing scheduling, the GSMA helps maintain efficient data flow within the WBAN. This paper presents the design and implementation of the GSMA-based approach within the 802.15.4 framework. Simulation results are presented to evaluate the effectiveness of the proposed method in improving reliability, reducing packet loss, and enhancing overall network performance in WBANs. The findings demonstrate the potential of the GSMA to address the limitations of 802.15.4 and contribute to developing more reliable and efficient WBAN solutions for healthcare applications.

Published: December 2024

Abstract Microbial-induced carbonate precipitation (MICP) has emerged as a promising eco-friendly and cost-effective alternative for improving the strength and stability of low-cohesion soils. This review provides an in-depth analysis of the microscopic mechanisms, implementation methods, and macroscopic properties of MICP in soil enhancement. The biogeochemical processes underlying MICP, including urea hydrolysis, denitrification, sulfate reduction, photosynthesis, and iron reduction, are discussed in detail. Various MICP implementation methods, such as two-phase treatment, one-phase treatment, and ex-situ mixing, are reviewed, highlighting their respective advantages and limitations in reinforcing low-cohesion soils. The review also addresses the performance of MICP-treated soils, including improvements in strength, stiffness, permeability, and durability. Furthermore, the key challenges and future prospects for microbial soil reinforcement technologies are summarized. Future research should focus on optimizing nutrient supply, enhancing bacterial retention and activity, controlling the crystallization process, conducting pilot projects, and reducing treatment costs. These efforts are crucial for advancing the practical application of MICP in sustainable infrastructure construction. This review aims to advance the understanding of MICP and its potential for sustainable soil improvement, offering valuable insights for geotechnical engineers.
Reimagining the American Union
Authors: Legomsky Stephen H. 
Published: January 2025

Reimagining the American Union challenges readers to imagine an America without state government. No longer a union of arbitrarily constructed states, the country would become a union of its people. The first book ever to argue for abolishing state government in the US, it exposes state government as the root cause of the gravest threats to American democracy. Some of those threats are baked into the Constitution; others are the product of state legislatures abusing their already-constitutionally-outsized powers through gerrymanders, voter suppression schemes, and other less-publicized manipulations that all too often purposefully target African-American and other minority voters. Reimagining the American Union goes on to demonstrate how having three levels of legislative bodies (national, state, and local) – and three levels of taxation, bureaucracy, and regulation – wastes taxpayer money and pointlessly burdens the citizenry. Two levels of government – national and local – would do just fine. After debunking the offsetting benefits typically claimed for state government, the book concludes with a portrait of what a new, unitary American republic might look like.

AbstractFengYun‐3E (FY‐3E) was the first operational meteorological satellite in China in early morning orbit. The radiation dosimeter, which is part of the satellite's Space Environment Monitor (SEM), contains three probes to measure the total ionizing dose in the three directions of the satellite. Improvements in the dosimeter have been made to increase detection sensitivity. The RADFET, a radiation dose sensor, was calibrated using 60Co radionuclide source to correlate its threshold voltage shift with the total ionizing dose. The improved dosimeter has a sensitivity of 0.06 rad (Si) to 0.45 rad (Si) in the measurement range. The flight data showed that the total ionizing dose within the FY‐3E satellite is anisotropic. The radiation dose rate in the +X and +Y directions increased by a few factors after the geomagnetic storms.
Advancing Enhanced Weathering Modeling in Soils: Critical Comparison With Experimental Data

Published: December 2024

AbstractEnhanced weathering (EW) is a promising strategy to remove atmospheric by amending agricultural and forestry soils with ground silicate rocks. However, current model‐based EW assessments face large uncertainties stemming from the intricate interplay among soil processes, compounded by the absence of a detailed comparison with available observational data. Here, we address this critical gap by first advancing a dynamic, ecohydrological, and biogeochemical Soil Model for Enhanced Weathering (SMEW). We then conduct a hierarchical model‐experiment comparison with four experimental data sets of increasing complexity, from simple closed incubation systems to open mesocosm experiments. The comparison demonstrates SMEW's ability to capture the dynamics of primary variables, including soil moisture, alkalinity, and inorganic carbon. The comparison also reveals that weathering rates are consistently lower than traditionally assumed by up to two orders of magnitude. We finally discuss the implications for carbon removal scenarios and avenues for further theoretical and experimental explorations.

AbstractGermline inactivating mutations of the SLC25A1 gene contribute to various human disorders, including Velocardiofacial (VCFS), DiGeorge (DGS) syndromes and combined D/L-2-hydroxyglutaric aciduria (D/L-2HGA), a severe systemic disease characterized by the accumulation of 2-hydroxyglutaric acid (2HG). The mechanisms by which SLC25A1 loss leads to these syndromes remain largely unclear. Here, we describe a mouse model of SLC25A1 deficiency that mimics human VCFS/DGS and D/L-2HGA. Surprisingly, inactivation of both Slc25a1 alleles results in alterations in the development of multiple organs, and in a severe proliferation defect by activating two senescence programs, oncogene-induced senescence (OIS) and mitochondrial dysfunction-induced senescence (MiDAS), which converge upon the induction of the p53 tumor suppressor. Mechanistically, cells and tissues with dysfunctional SLC25A1 protein undergo metabolic and transcriptional rewiring leading to the accumulation of 2HG via a non-canonical pathway and to the depletion of nicotinamide adenine dinucleotide, NAD+, which trigger senescence. Replenishing the pool of NAD+ or promoting the clearance of 2HG rescues the proliferation defect of cells with dysfunctional SLC25A1 in a cooperative fashion. Further, removal of p53 activity via RNA interference restores proliferation, indicating that p53 acts as a critical barrier to the expansion of cells lacking functional SLC25A1. These findings reveal unexpected pathogenic roles of senescence and of p53 in D/L-2HGA and identify potential therapeutic strategies to correct salient molecular alterations driving this disease.
Influence of Ni and Be elements on Al‐Mg‐Si alloys in different states

Published: December 2024

AbstractTo improve the comprehensive performance of Al‐Mg‐Si alloy conductors in overhead power lines, enhance the energy‐saving and emission‐reduction efficiency of transmission links, and reduce line loss indicators, this paper investigates the effects of trace Ni and Be elements on the electrical conductivity and mechanical properties of Al‐Mg‐Si alloys in the as‐cast, extruded and ageing states, and explores their effects on the microstructure of aluminium alloys in different states through OM, SEM and TEM. The results show that the addition of Ni and Be improves the comprehensive performance of the extruded state of aluminium alloys and greatly increases the tensile strength of the ageing state of aluminium alloys but has some effects on the electrical conductivity. The Ni element is able to refine the grain size of the as‐cast aluminium alloys and extruded aluminium alloys and promotes the precipitation of precipitated phases in the ageing state of aluminium alloys. The Be element has no obvious effect on the grain refinement of cast and extruded aluminium alloys, but it also promotes the precipitation of precipitated phases in ageing aluminium alloys and slows down the growth of the precipitated phases.

Quantum information technologies hold immense promise, with quantum computers poised to revolutionize problem-solving capabilities. Among the leading contenders are solid-state spin-qubits, particularly those utilizing the spin of phosphorous donors (31

ions for implantation, aiming to reduce placement uncertainty while maintaining detection efficiency. We examine energy transfer, molecule integrity, implantation profiles, electronic signal components, and stable damage. Among other things we find that the assumption that the molecule only breaks apart immediately due to the presence of an a-SiO2 layer on the surface of the crystal and that the intensity of the electronic signal from ion-solid interactions does not correlate necessarily with the penetration depth of P.
A STUDY OF FEEDBACK LOOP MECHANISMS REGULATING CALCIUM, IP3 AND DOPAMINE IN NEURONS
Authors: PAWAR ANAND , PARDASANI KAMAL RAJ 
Published: January 2025

Abstract
The present work primarily aims to explore the neuronal calcium (Ca2+), IP3, and dopamine (DA) signaling systems through a feedback loop model. To date, there has been no exploration of this feedback model in fractional-order dynamical systems. This feedback loop model incorporates several crucial mechanisms like the buffering process, IP3-receptor, ryanodine receptor, plasma membrane Ca2+ ATPase (PMCA) and sarcoplasmic/endoplasmic reticulum calcium ATPase (SERCA) pump, leak, sodium-calcium exchanger (NCX), voltage-gated Ca2+ channel (VGCC), Orai channels, DA-dependent IP3 synthesis, and others. By incorporating these mechanisms, the model aims to provide a more comprehensive and realistic understanding of the system under investigation. The present model incorporates fractional-order dynamics along both spatial and temporal dimensions to examine the impacts of superdiffusion and memory showing Brownian motion (BM) of Ca2+, IP3, and DA signaling molecules. The bidirectional feedback between calcium and IP3 signaling systems, unidirectional feedback between calcium and dopamine signaling systems, and unidirectional feedback between IP3 and dopamine signaling systems have been incorporated into the present model. These feedback loops establish interactions among calcium, IP3, and dopamine signaling systems within neuronal cells. The numerical findings were obtained by using the Crank-Nicholson (CN) method with the Grunwald technique for fractional space derivatives and the L1 method for fractional time derivatives in conjunction with the Gauss-Seidel Iterations (GSI). This research specifically investigates the implications of cell memory as well as superdiffusion on Ca2+, IP3, and DA dynamics in neuronal cells, which are interactive nonlinear systems. The superdiffusion process results in a reduction in Ca2+, IP3, and DA concentrations, while cellular memory leads to an increase in ion and molecule concentrations in neuronal cells during the initial time. The disruption of any given process can lead to imbalances in calcium, IP3, and DA systems, hence contributing to neurotoxicity and cellular demise.
Ontological absurdity
Authors: Ashe Laura 
Published: January 2025

Abstract
This chapter conducts an extended close comparison of the Knight’s Tale with Chaucer’s source, Boccaccio’s Teseida. It argues that in his adaptation of this classical and pagan-set romance, Chaucer has created a significantly darker picture of a world in which human characters lack free will, and are subject to arbitrary and malevolent forces. His characters are shown to be painfully aware of their subjection to fate and the gods, and the events of the narrative uphold this fatalism. However, Chaucer has simultaneously, contradictorily, given them an incipiently Boethian and Christian expectation of a benevolent and providential divinity—an expectation which the tale serially denies. Chaucer’s Boethian additions are analysed in comparison with the relevant passages of Boece, showing the emptying out of the latter’s consolatory force; it is further argued that ‘love’ and pitee in the tale fail to function as they should. The Knight’s Tale is a bleak depiction of an unjust world, in which human beings struggle to create meaning; and because Chaucer has allowed Christian ontology to enter this picture, it represents a profound challenge to theodicy.
