ABSTRACT Electronic skins capable of precise tactile perception under large mechanical deformations are critical for the advancement of soft robotics and wearable interfaces. However, achieving force and position perception in ultrathin flexible sensors while maintaining stable p...

Interpretable machine learning for identifying mild cognitive impairment among Chinese patients with obstructive sleep apnea: a multicenter cross-sectional study

Mild cognitive impairment (MCI) is clinically relevant in obstructive sleep apnea (OSA). We developed and externally validated an interpretable machine-learning model for concurrent clinically defined MCI to support prioritization for formal cognitive assessment rather than diagn...

Optimized scandium doping in Al₂Mo₃O₁₂ with NP co-doped carbon coating for enhanced low-temperature lithium storage

The development of low-temperature anode materials is crucial for the practical application of lithium-ion batteries (LIBs). Al 2− x Sc x Mo 3 O 12 ( x = 0, 0.5, 1, 1.5) materials were synthesized using a high-temperature solid-state method, and the effects of scandium doping on...

A Hierarchical Semantic Knowledge-Distilled Belief Rule Base for Interpretable Fault Diagnosis

Fault diagnosis is essential for the safe and reliable operation of industrial equipment. Deep learning models provide strong fault recognition capabilities, but offer limited transparency, while belief rule bases (BRBs) provide explicit reasoning, but face challenges in represen...

Construction of rGO/WO3/SiNWs Ternary Composite Structure and Its Low-Temperature NO2 Gas-Sensing Performance

To address the issues of low sensitivity and high operating temperature in silicon nanowire (SiNWs)-based NO2 sensors, this study constructs a ternary rGO/WO3/SiNWs heterostructure by spin-coating reduced graphene oxide/tungsten oxide (rGO/WO3) composites onto SiNWs surfaces. Sys...

Land-cover classification stability tracks divergent productivity and water-use-efficiency trajectories across boreal woody vegetation in the Daxing’anling Mountains

Annual land-cover labels are often treated as fixed ecological classes, yet boreal pixels near canopy-cover thresholds may repeatedly alternate between forest and woody-savanna categories. We tested whether classification persistence identifies distinct long-term carbon–water tra...

All-Weather Dual-Energy-Driven Sandwich-Structured Composite Membrane for Continuous Desalination and Water Purification

Abstract Interfacial solar evaporation has emerged as an energy-efficient approach for seawater desalination. Nevertheless, the practical application of conventional solar evaporators remains constrained by their strong dependence on sunlight, resulting in markedly reduced evapor...

The formation and negotiation of hybrid identity: A multimodal discourse analysis of Chinese intangible cultural heritage vloggers' videos on Douyin

This study examines how intangible cultural heritage (ICH) vloggers on Douyin negotiate hybrid identities under platform pressures. Integrating Multimodal Discourse Analysis (MDA) with Integrative Identity Negotiation Theory (IINT), we propose a Platform-Based Integrative Identit...

Incentive and Restraint Mechanisms for Collaborative Innovation of Green Intelligent Building Technologies Toward Low-Carbon and Digital Transformation in the Construction 5.0

Against the dual backdrop of the “dual carbon” goals and the digital transformation of the construction enterprises (CEs), green intelligent building technologies (GIBTs) have become the core driving force for improving quality and efficiency in the CEs and achieving low-carbon,...

Identifying ecosystem service drivers to inform land use scenario simulation: An InVEST-PLSR-PLUS framework for the Danjiangkou Reservoir Basin, China

The Danjiangkou Reservoir Basin is the core water source of the Middle Route of China's South-to-North Water Diversion Project, yet research in this basin has largely focused on static ecosystem service (ES) assessments, leaving the drivers of ES dynamics and their future traject...

A networked analysis model of the relationship between metacognitive ability and online learning engagement

The worldwide expansion of online learning has highlighted its persistently low completion rates; insufficient learning engagement is regarded as a central driver. Metacognitive ability—supporting self-regulation and strategic optimization in digital settings—has been theoretical...

Pressure‐Induced Single‐Molecule Deformation Enables 208‐Fold Photoluminescence‐Intensity Enhancement in Zero‐Dimensional Copper Iodide Hybrids

ABSTRACT Hybrid metal halides exhibit diverse excited‐state behaviors, yet the molecular‐level origin of pressure‐induced emission enhancement (PIEE) remains elusive. Here, we develop a rational molecular design strategy to isolate pressure‐induced single‐molecule deformation as...

A DEMATEL–AHP-based suitability assessment framework for geothermal water extraction from low- to medium-temperature sedimentary-basin resources: a case study of Lindian County, China

Existing assessments of geothermal water extraction suitability in sedimentary basins are often limited by subjective indicator selection, insufficient consideration of inter-indicator relationships, and weak adaptability to low- to medium-temperature geothermal systems. Taking L...

Recent advances of non-noble metal catalysts for efficient water electrolysis: types of water reactors, reaction mechanisms, and catalyst categories

Electrocatalytic water splitting offers a sustainable pathway for hydrogen production, yet the high cost and sluggish kinetics of noble-metal catalysts (e.g., Pt, IrO 2 , and RuO 2 ) severely hinder its commercialization. Recently, non-noble metal electrocatalysts have shown exce...

Integrated physiological and transcriptomic analyses reveal the mechanisms of exogenous selenium-mediated alleviation of saline-alkali stress in tomato seedlings

Abstract Background Tomato growth is severely constrained by saline-alkali stress. Although the mitigating effects of exogenous selenium on various abiotic stresses have been documented, its physiological and molecular regulatory mechanisms in tomato seedlings under saline-alkali...
