Study on Thermal Properties and Crystallization Behavior of Silica‐Modified Polyetheretherketone Composites

ABSTRACT This study employs KH560 to surface‐modify nano‐SiO 2 , which is then melt‐blended with PEEK to prepare composites with loadings of 0–7 phr. At 3 phr, the melting temperature rose to 348.5°C, the melting enthalpy reached a maximum of 80.33 J g −1 , and the corrected crys...

Spatiotemporal Regulation of Hierarchical Assembly of Hydroxyapatite for Enamel Remineralization

ABSTRACT The hierarchical structure of tooth enamel confers exceptional mechanical robustness, yet its biomimetic regeneration remains a significant challenge. We develop an enzymatic mineralization system (EMS) that achieves enamel regeneration by directing the hierarchical asse...

Comparing Random K-Fold and Spatial Block Cross-Validation for Predicting Post-Fire Vegetation Recovery

Spatial autocorrelation (SAC) can make random cross-validation optimistic for ecological and remote-sensing data, so spatial block cross-validation (SBCV) is widely recommended. How much SBCV changes model assessment depends on how far SAC extends relative to training–test separa...

Self-Adaptable Deep Eutectogels with High Stretchability, Low Hysteresis, and Long-Term Stability for Wearable Strain Sensors

Abstract Hydrogels are widely used in wearable flexible sensors, but suffer from dehydration, freezing, and bacterial growth under harsh environments. Here, we present a low-hysteresis eutectogel by incorporating quaternary ammonium chitosan (QCS) into an electrostatically driven...

Organized communities as pre-existing infrastructures of care during the COVID-19 pandemic: A transnational dialogue

This article draws from a community-engaged study of how ordinary people's social justice mobilization during the COVID-19 pandemic in Brazil, Canada, Germany, and Peru placed demands on local and national governments for equitable social policies. It challenges celebratory narra...

Process-Oriented Assessment of Project-Based Learning in Analytical Chemistry: Tracking Students’ Experimental Decision-Making Pathways

Learning analytical chemistry requires not only mastery of analytical and calculation methods but also the ability to make consistent experimental decisions. This study tested a process-oriented assessment framework based on the experimental decision-making pathway (EDMP) constru...

Persistent Menthol Hydrogen-Bonding Networks Govern the Structure and Hydration of a Hydrophobic Natural Deep Eutectic Solvent: Insights from NMR and Molecular Dynamics Simulations of the Camphor–Menthol System

Abstract Natural deep eutectic solvents (NADES) based on monoterpenoids have emerged as promising hydrophobic, biodegradable media. Despite their widespread use, the molecular interactions governing the formation and hydration behavior of camphor–menthol NADES remain insufficient...

Longitudinal assessment of the retinal phenotype in patients with Fabry disease undergoing continuous enzyme replacement and/or chaperone therapy

Abstract Purpose Fabry disease (FD) is an X-linked inherited lysosomal storage disorder caused by deficiency of the enzyme α-galactosidase A. This study describes the long-term evolution of retinal findings in genetically confirmed FD patients, who have been receiving enzyme repl...

CELEBRITY ENDORSEMENT AND CUSTOMER TRUST IN NIGERIAN BANKS

The study examined the influence of celebrity endorsement and customers trust in Nigeria banks. Specific objectives were to: examine the influence of celebrity attractiveness on customers’ transparency in Nigerian Banks and ascertain the influence of celebrity likeability on cust...

A Fast and Generalizable Deep Neural Network for the Detection of Atrial Fibrillation

Atrial fibrillation (AFib) is the most prevalent sustained cardiac arrhythmia, yet most deep learning detectors are validated on a single cohort and few report uncertainty. We developed a compact 14M-parameter convolutional neural network for binary AFib classification from 10 s,...

Ash Geometry™: A Five-Layer Model of Occult Semiotics and Symbolic-System Construction

Occult symbolic systems encompass inherited seals, magical alphabets, talismanic diagrams, and methods for constructing new sigils. Ash Geometry™ proposes an author-developed framework within this field: the occult symbol is treated as a constructed semiotic architecture whose me...

Prognosis of acute symptomatic seizures and impact of prolonged treatment with anti‐seizure medication

Abstract Objectives Acute symptomatic epileptic seizures (ASySs) occur in temporal proximity to acute brain insults. Given their low risk of subsequent unprovoked seizures, current guidelines recommend either no treatment with anti‐seizure medication (ASM) or early discontinuatio...

This repository contains the official implementation, machine-checked security proofs, and academic manuscript for CLH MAX, a Post-Quantum Key Encapsulation Mechanism (KEM). Technical SpecificationsCLH MAX is designed over the polynomial ring Z_q[X]/Φ₂₅₇(X). By explicitly utilizi...

Multi-Objective Minimal Feature Selection for Explainable-by-Design Classification: Equivalence-Aware Selection and Rashomon-Set Analysis Across Six Domains

High-stakes and regulated decision-support systems require predictive models that are simultaneously accurate and interpretable, yet accuracy is frequently obtained through opaque models whose behaviour is difficult to audit. This paper develops an explainable-by-design classific...

AI Companions and Loneliness: Conceptualizing and Operationalizing Synthetic Mindfulness and Exploring Its Role in Alleviating Loneliness

ABSTRACT The rise of AI companions has sparked interest in their potential to alleviate the growing social problem of loneliness, yet evidence of their effectiveness remains unsettled. Drawing on social surrogacy theory with a theories‐in‐use approach, this research introduces sy...

Current Status of Tuberculosis and Human Immunodeficiency Virus Co-Infection in the Philippines: A Narrative Review

Tuberculosis (TB) and human immunodeficiency virus (HIV) co-infection remains a major public health concern globally and in the Philippines. The country continues to face a high burden of TB, multidrug- and rifampicin-resistant TB (MDR/RR-TB), HIV, and HIV-associated TB. Since HI...
