Enabling temporal transitions: AI adoption and sequential ambidexterity in Chinese SMEs from 2015–2023

With research about sequential ambidexterity suggesting that firms may approximate ambidexterity over time by alternating between periods of exploration and exploitation, this temporal approach provides a feasible solution for SMEs facing resource limitations to manage the tensio...

Extracting sea-ice in the arctic by integrating microwave scattering mechanisms with superpixel-based synergistic constraints

High-resolution, fine-scale sea-ice extraction is essential for assessing navigation risk in Arctic shipping routes. Synthetic aperture radar (SAR) provides all-weather observations and is therefore a key data source for polar sea-ice classification. However, conventional pixel-l...

Shared genetic architecture between constipation and aging-related phenotypes

While the frequency of constipation increases sharply with age, the genetic links between constipation and aging-related phenotypes remain largely unexplored. So far, research has typically focused only on individual characteristics while neglecting broader genetic connections. I...

Ferroptosis-related immune microenvironment and prognostic signature in high-grade endometrial carcinoma: integrated bulk and single-cell analysis

Abstract Background High-grade (FIGO Grade 3) uterine corpus endometrial carcinoma (UCEC) is an aggressive malignancy with limited therapeutic options and a poor prognosis. While ferroptosis is implicated in various cancers, its specific role within the tumor immune microenvironm...

Experimental and DFT insights into the oxidation-induced deterioration of sodium butyl xanthate adsorption on pristine and hydroxylated (001) surfaces of carrollite (CuCo2S4)

Cobalt is a strategically important metal, but its efficient recovery from increasingly complex ores remains challenging. Flotation is widely used to recover cobalt sulfide minerals such as carrollite, with xanthates serving as common collectors. However, surface oxidation can im...

Disease‐Specific Optimal Blood Glucose Control Strategies in Critically Ill Patients: Retrospective Cohort Study and Network Meta‐analysis

ABSTRACT Background Optimal glucose targets for critically ill patients are likely to vary by underlying condition, yet a ‘one‐size‐fits‐all’ approach persists. Aim Determining disease‐specific glucose thresholds may help achieve the lowest mortality rates. Study Design This stud...

Ultra‐Sensitive, Decoupled Multimodal Sensing via Dual‐Network Iontronic Organohydrogels

ABSTRACT Flexible sensors capable of mimicking human skin's multimodal perception are highly desired for wearable electronics. However, achieving inherently decoupled detection of multiple physical stimuli in a single device remains a fundamental challenge. Here, a polyacrylamide...

High‐Purity Hydrogen Production From Water–Gas Shift Reaction in a High‐Temperature Polymer Electrolyte Membrane Electrolyzer

ABSTRACT The water–gas shift reaction (WGSR) is a critical pathway for hydrogen production, yet current methods face trade‐offs between purity and scale. Thermocatalytic WGSR achieves high product purity but requires energy‐intensive gas separation, while room‐temperature electro...

Safety-critical trajectory segment generation for autonomous driving testing in vehicle-to-two-wheeler blind-spot emergence scenarios

Objective Safety validation of autonomous driving systems (ADS) is constrained by the rarity of safety-critical interactions in naturalistic driving and the difficulty of generating realistic multi-agent trajectories from reconstructed crash data. This study focuses on a common u...

Association between dental caries experience measured by dmft and oral health-related quality of life among preschool children: a cross-sectional study

Abstract Objective To examine the association between dental caries experience, measured using the decayed, missing, and filled deciduous teeth index (dmft), and parent-reported oral health-related quality of life (OHRQoL) among preschool children in Changde, northwestern Hunan,...

Coupled adaptive neural network control for active suspension of deep-sea mining tracked vehicles under hydrodynamic effects and multiple parametric uncertainties

Deep-sea mining tracked vehicles are subject to substantial parametric uncertainty from hydrodynamic effects, soft-seabed interaction, suspension nonlinearities, and actuator degradation. This paper proposes a coupled adaptive neural network (CANN) strategy for an 8-DOF six-wheel...

Recovery of silver from end-of-life photovoltaic cells via mild glucose reduction to produce high-purity ultrafine silver powder for conductive silver paste

Recovering silver from end-of-life (EoL) photovoltaic (PV) cells is of great significance for closing the resource loop in the photovoltaic industry. Currently, the conventional silver recovery processes mainly include acid leaching, chlorination precipitation, ammonia dissolutio...

A fire–evacuation coupled modeling and passenger behavior analysis in high-speed train carriages under the dynamic effect of fire

The interior of high-speed train carriages is enclosed, narrow, and elongated, which significantly deteriorates evacuation conditions during a fire. High temperature, reduced visibility, and carbon monoxide (CO) exposure can severely affect evacuation efficiency. This study propo...
