Sustainable gamma radiation–assisted synthesis of ZnO nanoparticles on acrylic fabric for durable antibacterial and UV-protective performance

This study demonstrates the successful synthesis of zinc oxide nanoparticles (ZnO NPs) on acrylic (PAN) fabrics via gamma radiation. PAN fabrics were padded with an alkaline zinc nitrate solution of 0.1 and 0.2 M, before treatment with 2% w/v of poly(vinyl alcohol) (PVA). Gamma r...

A multicenter pilot study of nivolumab with drug-eluting bead transarterial chemoembolization in patients with liver-limited hepatocellular carcinoma

Background Drug-eluting bead transarterial chemoembolization (deb-TACE) is a standard for liver-limited, locally advanced hepatocellular carcinoma (HCC) and may enhance response to immune checkpoint inhibition through tumor immune microenvironment modulation. We evaluated nivolum...

Improving few-shot stance detection with MINE: meta-prompting and in-context N-shot examples

Abstract Stance detection aims to identify an author’s stance toward a target topic. Although recent prompting-based methods enable zero- and few-shot stance detection with large language models (LLMs), they often require extensive prompting or costly use of multiple LLM agents,...

Spiral Random Walk-Enhanced Puma Optimizer for Side Lobe Suppression and Null Control in Array Antenna Design

This study proposes a spiral random walk enhanced puma optimizer (SRW-PO) for array antenna design. The method preserves the hunting and ambush search structure of the classical puma optimizer (PO) while embedding two complementary mechanisms into its update process. The adaptive...

Author's Archive of Research Materials Published on the CALAMEO Digital Publishing Platform

This preprint presents the author’s archive of research materials published on the CALAMEO digital publishing platform. The archive includes books, articles, preprints, research notes, educational materials, and numerical studies in seismic exploration, geophysics, applied mathem...

From Seaweed to Corrosion Inhibitor: A Multi-MethodValidation of λ-Carrageenan as a Non-Toxic Inhibitorunder Acidic Hydrodynamic Conditions

Abstract Corrosive processes are responsible for direct and indirect costs in industrial systems, which can be mitigated by corrosion inhibitors. The awareness of environmental risks has motivated sustainable approaches, such as naturally derived biopolymers, due to low toxicity...

Gamified learning across academic stages: a developmental perspective on motivation, collaboration, and identity in computer engineering education

Research on gamification in higher education has expanded significantly; however, limited attention has been paid to how students’ experiences with gamified learning evolve across academic stages and processes of disciplinary identity development. This study compares perceptions...

Harmonically Resonant Lattice Prediction Engine — E8 Intelligence Research

Using the 132Hz E8 base frequency as a phase modulator, we map "forward attempt" lottery lead sequences to E8 root lattice projections where phi-coupled harmonic resonance creates transient stable domains. These domains correspond to Rogers-Ramanujan modular forms that statistica...

Global Cowling Effects in the Sq‐EEJ Current System Under Electrostatic Approximation: Theoretical Simulation

Abstract The solar quiet (Sq) current and equatorial electrojet are widely known as one of the fundamental currents in ionosphere. Although the Sq‐EEJ current system has been extensively investigated, the manner in which Hall and Pedersen current components collectively organize...

A Machine Learning Approach to Latent Structure Learning for Zero-Inflated Patent Keyword Count Data

Patent document–keyword count data are typically high-dimensional, sparse, and dominated by zero entries, which makes it difficult to simultaneously reconstruct keyword frequencies and identify meaningful technological structures. This study proposes a machine learning approach t...

Changes in Emergency Department Pediatric Readiness, Inpatient Services, and Excess Child Deaths

Importance Emergency department (ED) pediatric readiness and pediatric inpatient services have changed over time in many hospitals, but the impact of these changes on pediatric outcomes is unclear. Objective To evaluate pediatric mortality associated with changes to ED pediatric...

Safety, efficacy and angiographic outcomes of the Lattice flow diverter for intracranial aneurysms: A systematic review and meta-analysis

Introduction The Lattice flow diverter is a novel mechanical balloon-based device designed to enhance wall apposition and optimize aneurysm neck coverage. Yet, its safety, efficacy, and angiographic outcomes have not been systematically evaluated. Methods A systematic review and...

Multi-Temporal UAV Observations of Post-Seismic Surface Collapse Evolution Following the 2026 M5.2 Liuzhou Double Earthquake in a Karst Terrain, Guangxi Province, China

On 18 May 2026, a M5.2 double earthquake struck the Taiyangzhen area of Liunan District, Liuzhou City, Guangxi, China, triggering shallow surface collapses in this karst terrain. We conducted three UAV orthophoto surveys of the meizoseismal area on 20 May, 23 May, and 24 May, and...

From Student Support to Transformative Education: Reinterpreting University Mentoring Through the Lens of Education for Sustainability

Mentoring is widely recognized as a strategy for supporting students’ academic and personal development, yet its role in the Education for Sustainability (EfS) remains poorly understood. Meanwhile, universities have expanded sustainability policies, governance structures, and cur...

Unexpected Suppression of Tomato Fruit Cuticle Formation by Overexpression of a Key Cutin Biosynthetic Enzyme

Fruit cuticles regulate the diffusion of water, gases and solutes, functioning as essential protective interfaces against environmental and biotic stresses. Engineering cuticle structure and mechanics therefore represents a promising strategy for improving fruit quality and resil...

Salivary Aldosterone as a Biomarker for Obstructive Sleep Apnea: Diagnostic Performance and the Moderating Role of Mean Arterial Pressure—A Cross-Sectional Study

Obstructive sleep apnea (OSA) is associated with renin–angiotensin–aldosterone system (RAAS) dysregulation. This study examined the relationship between salivary aldosterone and OSA severity, identified predictors of salivary aldosterone, evaluated the moderating role of mean art...

Probing relaxed myosin states in hypertrophic cardiomyopathy by second harmonic-generation microscopy

This study explores the use of polarized second-harmonic generation (pSHG) to investigate myosin conformation in the relaxed state, differentiating between the actin-available, disordered (ON) state and the energy-conserving, ordered (OFF) state. By shifting the ON/OFF equilibriu...
