Triangulated Dialogic Space in Arts and Design’s Studio Pedagogy

Despite decades of research demonstrating the learning benefits of dialogic pedagogy, its implementation in K-12 classrooms remains rare. Three structural challenges account for the difficulties of initiating and sustaining dialogic space in classrooms: managing face-threatening...

Modeling Investment Decisions in Renewable Energy and Cryptocurrency Mining Under Uncertainty

Operations research has long contributed to addressing energy and environmental challenges through mathematical modeling and decision-support methods. In particular, numerous studies have examined investment planning, capacity expansion, and policy design for renewable energy sys...

One (Noisy) Bit to Rule Them All: Key Recovery from Randomness Leakage in ML-DSA

Abstract The Fiat-Shamir transform is one of the most widely applied methods for secure signature construction. Fiat-Shamir starts with an interactive zero-knowledge identification protocol and transforms this via a hash function into a non-interactive signature. The protocol’s z...

Terpene-DerivedCarvyl Acetate Dicarbonate: A NovelMonomer for Biobased Nonisocyanate Poly(hydroxyurethane) Thermoplasticsand Thermosets

Abstract New thermoplastic nonisocyanate poly(hydroxyurethanes) (NIPUs) have been designed by polyaddition reactions of carvyl acetate dicarbonate (CADC) with a range of commercial diamines, yielding thermoplastic nonisocyanate poly(hydroxyurethanes) with moderate molecular weigh...

Optimizing diphenyl(2,4,6‐trimethylbenzoyl)phosphine oxide concentration and post‐curing time to balance mechanical properties and color stability in a three‐dimensional‐printed restorative resin

Abstract Three‐dimensional (3D) printing is widely used in dental restorations; however, optimization of photoinitiator concentration and post‐curing protocols remains critical to achieve a balance between mechanical and esthetic performance. This study evaluated the combined eff...

Knowledge-Guided Graph iTransformer Enhanced by Reinforcement Learning for Industrial Fault Diagnosis

Complex industrial processes are characterized by strong coupling, nonlinear interactions, and dynamic causal dependencies between variables, posing significant challenges for accurate fault diagnosis. Conventional data-driven methods often fail to effectively exploit structural...

A Visual Detection and Multi-Zone Personnel Safety Control Method for Firework Manufacturing Workshops

Real-time visual detection is essential for personnel safety control in firework manufacturing workshops, where inadequate personnel-count control can increase safety risks in hazardous production zones. This study proposes a visual detection and multi-zone personnel safety contr...

An Agent-Based Model of the Stellar Mass Distribution

The Initial Mass Function (IMF) describes the distribution of stellar masses formed in a stellar cluster and constitutes a fundamental constraint for theories of star formation. In this work, we investigate the emergence of the IMF slope using a minimal agent-based model inspired...

Effects of Additive Incorporation on Fluoride Release of Orthodontic Glass Ionomer Cements and Adhesives: A Systematic Review

This systematic review evaluated the effects of functional additives on fluoride release, fluoride recharge/re-release, and selected mechanical, physical, and biological properties of orthodontic glass ionomer cements (GICs) and glass ionomer-based adhesives. The review followed...

Symbiotic visual creativity in higher education: Escape-room pedagogy across analogue, digital, and AI-mediated practice

Visual creativity is increasingly recognised as a foundational competency in higher education, particularly within disciplines grounded in digital interaction, interface design, and multimodal communication. Yet foundational perceptual frameworks such as Gestalt principles are fr...

Dietary Modulationof Osteoporosis via Probioticsand the Gut–Bone Axis: From Mechanisms to Food Applications

Abstract Osteoporosis, a metabolic bone disorder affecting nearly one-third of women and one-fifth of men globally, poses a major public health burden. Current pharmacological treatments face limitations, driving interest in safer nutritional interventions. The gut–bone axis, thr...

Activatingthe Gate-Opening Effect in Multivariate MOFs by Defect Engineeringfor Oxidative Desulfurization

Abstract Metal–organic frameworks (MOFs) have shown great potential in catalytic oxidative desulfurization (ODS), yet their efficiency is often hampered by intrinsically inaccessible pore networks that impede the contact between active sites and reactants. To unlock the potential...

Unlocking the Potential of Sparingly Soluble LiNO 3 in Carbonate Electrolytes With Pyridine as a Carrier Cosolvent for 450 Wh Kg −1 High‐Voltage Lithium Metal Batteries

ABSTRACT LiNO 3 is a highly effective electrolyte additive for ether‐based lithium metal batteries, but its extremely poor solubility in carbonate electrolytes has long restricted its application in high‐voltage high‐energy‐density systems. In this study, we develop a pyridine ca...

We are not all the same: Preference-based market segmentation among public transport users in Soweto, South Africa

Identifying travel needs and preferences of different market segments is important in planning public transport systems. Preference-based market segmentation has been researched globally but rarely in the Sub-Saharan African context. This paper seeks to investigate variations in...

Multi-Time-Scale Distributed Voltage Optimization for AC/DC Hybrid Distribution Networks with High-Penetration Photovoltaics

After high-penetration distributed photovoltaics (DPVs) are integrated into AC/DC hybrid distribution networks, stochastic source-load fluctuations, AC-DC coupling, and heterogeneous response characteristics of voltage-regulation devices jointly aggravate voltage violations and r...

Postoperative factors associated with hazardous alcohol use after metabolic and bariatric surgery

Abstract Introduction There is an increased risk of hazardous alcohol use following metabolic and bariatric surgery (MBS). Identifying risk factors of hazardous alcohol use, particularly factors that may differentiate risk among those with regular postoperative alcohol consumptio...

Anion States andDissociation Pathways of the UniversalRadiosensitizer Model 2,4-Dichloro-5-nitropyrimidine

Abstract We present a computational investigation into the anion states of 2,4-dichloro-5-nitropyrimidine (NDP), focusing on dissociative electron attachment pathways motivated by recent mass spectrometry experiments. The molecule exhibits a unique combination of low-energy elect...

Contrasting Water-Use Strategies of Ailanthus altissima and Crataegus orientalis Under Drought Stress Reveal Restoration Potential in Mediterranean Drylands

Water availability is the primary environmental factor limiting plant establishment in arid and semi-arid ecosystems, and increasing drought-stress due to climate change is making forest restoration efforts in the Mediterranean basin increasingly critical. The Eastern Mediterrane...

When Institutions Become a Burden: Embedded Institutional Process Mapping as a Framework for Understanding Student Success

The transition into higher education is one of the most consequential junctures in a young person’s trajectory. Institutional retention is an institutional responsibility. When students leave before completing their degree, the default response has been to look at the student, th...
