Age-Associated Differences in Facial Skin Structure in Chinese Women: a Cross-Sectional Study

Facial skin aging is a process leading to structural degradation and visible phenotypical changes. Prior studies examined age-related skin parameters and suggested accelerated changes occurring in the early 30s, yet precise timing remains insufficiently defined, and few assessed...

Static-dynamic triggering mechanisms of rockburst in straight-walled arch roadways under different principal stress orientations and impact disturbances

This study investigates how principal-stress orientation affects impact disturbance triggered rockburst around straight-walled arch roadways. Coupled static-dynamic loading tests were conducted on specimens containing a straight-walled arch opening with orientation angles of 0°,...

Effect of adjunctive minocycline on functional recovery and safety in acute ischemic stroke: a systematic review and meta-analysis

Neuroinflammation drives secondary brain injury after acute ischemic stroke. Minocycline, a tetracycline antibiotic with anti-inflammatory properties, has shown promise in preclinical and early-phase trials. The recent EMPHASIS trial necessitates an updated evidence synthesis. We...

Micro-Water Migration Characteristics in Cable Oil-Filled Terminations and Their Effect on Insulation Performance

To investigate moisture ingress in the insulation of cable oil-filled terminations, this study first simulated moisture migration within a termination. Based on identified accumulation locations, the breakdown voltage of the silicone rubber (SiR)/cross-linked polyethylene (XLPE)...

From threat to reconfiguration: How content creators reshape occupational identity in AI-driven creative practices

Generative artificial intelligence (GenAI) is disrupting creative work and challenging occupational identities, yet limited research has examined how creators experience and respond to these changes. Drawing on Albert Ellis’s ABC model, this study investigates relationships among...

Exploratory thyroid ultrasound–computed tomography synthesis using anatomy-preserving contrastive unpaired translation

OBJECTIVES: When ultrasound (US) and computed tomography (CT) are both clinically indicated, unpaired image translation may support model development but cannot replace either examination. We evaluated Anatomy-Preserving Contrastive Unpaired Translation (AP-CUT), a CUT-based fram...

Triple-Cross-Linked Seawater-Sourced Hydrogels with Extreme Thermo-Shear Stability for Ultradeep Marine Reservoir Exploitation

Abstract Hydrogels play an important role as materials in the oil and gas industry. Direct preparation of hydrogels using seawater is attractive for offshore energy production but remains challenging because conventional partially hydrolyzed polyacrylamide with a single-cross-lin...

Near-neutral flotation of microfine ilmenite

Conventional ilmenite flotation strongly relies on sulfuric acid to improve the selectivity between ilmenite and associated gangue minerals, resulting in high reagent consumption, equipment corrosion and difficulties in process water recycling. In this study, a ternary Fe-BHA/NaO...

A continuous spiral-spring triboelectric nanogenerator for energy harvesting and self-sensing under ultra-low-frequency rotation

Self-powered monitoring of slowly rotating components is hindered by the small relative speed and limited installation space available to conventional rotary triboelectric nanogenerators (TENGs). Here, a continuously driven unidirectional rotary TENG (CDUR-TENG) is developed by i...

High peak-current AlGaAs tunnel junctions for 10-junction GaAs laser power converters

Laser power converters (LPCs) are the core photovoltaic devices that act as receivers in optical wireless power transmission systems. In these devices, tunnel junctions (TJs) are employed to vertically interconnect multiple absorption sub-cells in series to construct high-voltage...

Hypoxia‐Regulating Nanozymes for Biomedicine

Hypoxic microenvironments arise when local oxygen supply fails to meet cellular demand and exert an influence on the progression of cancer, ischemic heart and brain injury, chronic inflammatory disorders, and other diseases. Conventional approaches, including oxygen delivery syst...

Reconfiguring interfacial hydrogen-bond networks to enhance anodic oxidation for efficient wastewater treatment

Abstract Anodic oxidation is a pivotally electrochemical technology for wastewater treatment containing emerging contaminants such as isothiazolinone antimicrobials, but sluggish interfacial water-splitting kinetics for hydroxyl radical (•OH) formation and a limited oxidation ran...

Additive manufacturing of heterostructured metallic materials: Processing, microstructural characteristics, mechanical properties, and service performance

Developing high-performance metallic materials with excellent mechanical properties and reliable service performance is an everlasting objective of materials research. The perspective on heterostructured materials with dramatic differences in compositions and structures, in conju...

The dual Minkowski problem under group actions

In this paper, we study the dual Minkowski problem under group symmetry. For 0 < 𝑞 ≤ 𝑛 , we give a complete existence characterization in the framework of G -invariant convex bodies when the group 𝐺 ⊂ 𝑂 ⁡ ( 𝑛 ) has no nonzero fixed points, recovering the origin-symmetric setting...

Dynamic Supramolecular Hydrophobic Ionogels with Ultrafast Self-Healing for Reliable Underwater Electronics

Abstract Conductive ionogels integrating rapid self-healing, underwater stability, and reliable sensing capability are highly desirable for next-generation wearable electronics, yet remain challenging to achieve simultaneously. Herein, a multifunctional hydrophobic ionogel is dev...

Rock Bridge Fracture and Differential Deformation During Progressive Failure of Rock Slopes with Intermittent Joints Using a Stabilized Peridynamics Model

Progressive failure of rock slopes with intermittent joints involves crack propagation through intact rock bridges and the development of differential deformation. This study uses a stabilized non-ordinary state-based peridynamics model to investigate these processes. The model c...

Insect outbreak progression over three years shapes biogenic volatile emissions in a mountain birch forest

Abstract Geometrid moth outbreaks are important natural disturbances in mountain birch ( Betula pubescens ssp. czerepanovii ) forests of northern Fennoscandia and are expected to intensify with climate change. Impacts of these outbreaks and moth herbivory on biogenic volatile org...

In Situ Cellulose Removal from Wood: A Novel Strategy for Preparing Simulated 80,000-Year-Old Waterlogged Archaeological Wood

Abstract Waterlogged archaeological wood (WAW), characterized by extensive degradation of cellulose and hemicellulose with concomitant relative lignin enrichment, represents a vital yet vulnerable class of cultural heritage materials. Due to the scarcity of archaeological wood sp...
