Artificial Intelligence for Mineral Exploration Imagery: A Systematic Mapping Review of Data, Tasks, and Methods

Artificial intelligence (AI) is increasingly applied to image-based and image-formatted geoscientific evidence across mineral exploration, from regional and surface surveys to drilling/core analysis and laboratory characterization. However, the literature remains distributed acro...

Contrasting Prognostic Value of Discordance Between Resting Distal-to-Aortic Coronary Pressure Ratio and Fractional Flow Reserve in Coronary Artery Disease

BACKGROUND: Discordance between nonhyperemic pressure ratios and fractional flow reserve (FFR), observed in up to 20% of cases, complicates clinical decision-making for coronary revascularization and warrants further investigation of its clinical implications. This study aimed to...

Clinical Outcomes of Semi-Occlusive Dressing for Allen Type III Fingertip Injuries

Background/Objectives: Local flap coverage is still widely regarded as the treatment of choice for Allen type III fingertip injuries, and outcome data for conservative treatment remain limited. We evaluated the outcomes of semi-occlusive dressing for Allen type III fingertip inju...

Eliminating Texture‐Induced Retention of Self‐Assembled Monolayer Residues for High‐Performance Perovskite Solar Cells

Self-assembled monolayers (SAMs) constitute foundational interfacial elements in high-efficiency inverted perovskite solar cells (PSCs); however, ensuring chemical and electronic integrity across SAM-modified interfaces remains challenging. Although post-deposition solvent washin...

Wearable photovoltaic textiles: From device technologies to long‐term reliability

Abstract Photovoltaic (PV) textiles are emerging as a promising class of energy‐harvesting systems that combine solar conversion capability with the softness, porosity, and wearability of fabrics. Unlike conventional rigid modules, PV textiles are designed to conform to the human...

Ultrafine Sm2Fe17N3 soft actuators enabling robust operation at elevated temperature

Magnetoactive soft composites comprising hard magnetic particles embedded in elastomer matrices have emerged as a promising platform for programmable soft actuators capable of remote, untethered actuation. Ferromagnetic Nd 2 Fe 14 B particles, characterized by a high maximum ener...

Antimony-contact MoS2 FET gas sensors for reinforcement-learning–driven hazard perception at room temperature

Two-dimensional van der Waals semiconductors promise low-power chemical perception at room temperature, yet contact-limited on-currents and slow recovery impede closed-loop decision making in hazardous environments. Here we propose antimony (Sb)-contact two-dimensional (2D) monol...

Shape-Controlled Poly(N-isopropylacrylamide) Actuators Enabled by Tensile-Stress Mismatch for Temperature-Adaptive Textiles

Thermal comfort is a key determinant of human health and requires adaptive responses to dynamic environments. Here, we report a temperature-adaptive textile enabled by a tensile stress mismatch-driven poly(N-isopropylacrylamide) (PNIPAM) actuator operating within a human-friendly...

2D nanomaterials for near infrared responsive photomedicine: a review

The continuously growing demand for efficient and non-invasive treatment has accelerated the development of near infrared (NIR) responsive phototherapy, a therapeutic modality that leverages the biological transparent window (700–1850 nm) to enable deeper tissue penetration compa...

Old-age poverty, basic pension policy periods, and late-life suicide in South Korea: a descriptive ecological analysis, 2012–2024

South Korea has exceptionally high old-age poverty and late-life suicide rates. Both declined during a period spanning the 2014 introduction of the Basic Pension and subsequent benefit changes. We described their national trajectories from 2012 to 2024 and compared late-life suic...

Quantum Dot-Induced Kinetic Bottleneck in Singlet Exciton Relaxation of Conjugated Polymer Aggregates

Abstract We designed hybrid aggregate model systems with cascade energy alignment from conjugated polymers (CPs) to quantum dots (QDs) to investigate the effects of QDs on CP singlet (S1) excitons. Radiative recombination of S1 excitons occurs within 1 ps in the chlorinated CP/QD...

Design and experimental evaluation of a multi-winding gas-spring gravity compensation mechanism for high-torque sit-to-stand assistance

Conventional gravity compensators capable of handling large loads are often bulky and require hardware modifications for different payload ranges. This study presents a multi-winding gas-spring gravity compensation mechanism (MW-GCM) for high-torque sit-to-stand assistance and ev...

Short-Term Traffic Speed Prediction Integrating Traffic Flow Theory for Enhanced Urban Congestion Mitigation

Abstract Effective mitigation of urban traffic congestion requires accurate speed prediction. It also requires a proactive understanding of how traffic states evolve. Existing deep learning models often work as black boxes. They do not capture the underlying dynamics of traffic f...

Symptom-Based Hospitalization Risk Differs Between Ulcerative Colitis and Crohn’s Disease: A Nationwide Emergency Department Study

Presenting symptoms guide emergency department (ED) triage and admission decisions in inflammatory bowel disease (IBD), but whether symptoms have similar predictive value in ulcerative colitis (UC) and Crohn’s disease (CD) remains unclear. We examined disease-specific association...

A compact, wireless fluorimeter system for continuous, real-time monitoring of tissue perfusion via in vivo fluorescence signals

In vivo fluorescence signals provide physiological and pathological insights for the interpretation of biological states associated with anatomical abnormalities or disease. Conventional methods for measuring fluorescence signals rely on bulky, costly instrumentation for imaging...

Layer-by-Layer Electrode Design Integrating a Macroporous Carbon-Nanotube Skeleton for an Anion-Exchange Membrane Water Electrolyzer

Abstract Three-dimensional porous electrodes (anodes and cathodes) using only non-noble-metal electrocatalysts are important for enhancing the performance of anion-exchange membrane water electrolysis (AEMWE), contributing to reduced green-hydrogen production costs. This study de...

Diagnosing public transport disadvantage in multi-activity accessibility: Opportunity-side and service-side signals

Multi-activity daily travel requires access to several everyday opportunities within limited time budgets. Public transport (PT), however, often provides less effective door-to-door access to such opportunity combinations than private cars. Using scheduled PT and private-car trav...

Oral health and the risk of dementia: a systematic review, meta-analysis, and comparative evaluation against established systemic risk factors

Oral health has been increasingly associated with dementia and cognitive decline, but the magnitude and consistency of associations across distinct oral-health domains remain unclear. We systematically evaluated domain-specific associations between oral health conditions and deme...
