Prioritizing sustainable practices for decarbonizing construction SMEs: an actionable roadmap for capability development in developing economies

Purpose As the construction sector strives to meet global climate targets, small and medium-sized enterprises (SMEs) in developing economies represent a critical yet often overlooked frontier for decarbonization. Despite their significant role, construction SMEs face barriers suc...

Recent Increaseof Greenhouse Gas Emissions from Cryosphere-InfluencedReservoirs under Climate Change

Abstract Global warming leads to cryosphere degradation, transferring large amounts of terrestrial carbon and nitrogen to reservoirs, which may accelerate the release of greenhouse gases (GHGs) to the atmosphere. However, the spatial dynamics and decadal trends of GHG emissions f...

Chinese students’ L2 classroom engagement in college: Perceived teacher support, value beliefs and self-monitoring

<title>Abstract</title> Based on an integrated framework of the Self-Determination Theory and the Expectancy-Value Theory, this study investigated the link between students’ perceived teacher support and their L2 classroom engagement via two mediators: students’ value beliefs of...

Electronic Chip‐Mimetic Medical Implants for Controllable Sonothermal Treatments

ABSTRACT The sterility and controllable biological functionalities of implantable medical devices determine their lifespan, safety, and therapeutic efficacy. Inspired by the thermal effect of working electronic chips, which consist of various heterostructures, we have developed a...

Health-related fitness mediates the longitudinal association between engagement in fundamental movement skill-related activities and social interaction abilities in the ABCD study

Under the Know it-Do it-Love it (KDL) framework, structured physical activity is expected to support adolescents’ social development. Guided by the KDL concept, this study examined the longitudinal association between engagement in fundamental movement skill (FMS)-related activit...

Encoder Choice Outweighs Modular Refinement in U-Net Architectures for Globally Distributed Coseismic Landslide Segmentation

Rapid post-earthquake landslide mapping is critical for emergency response, yet the quantitative hierarchy of architectural choices in U-Net-based segmentation remains unresolved. Using the Globally Distributed Coseismic Landslide Dataset (GDCLD; nine earthquakes, four continents...

A distributed data governance architecture for smart cities based on data unified registration, dynamic catalog, and local LLM data coordination

Abstract Effective governance and secure sharing of data resources remain key challenges in smart-city development, where cross-department collaboration is constrained by data ownership boundaries and compliance requirements. This paper proposes a distributed data governance arch...

Chirality-induced spin-regulated synaptic dynamics in 2D perovskite memristors for polarimetric neuromorphic computing

Conventional von Neumann architectures face fundamental energy-efficiency bottlenecks, while current optoelectronic neuromorphic devices remain confined to simple optoelectronic responses, unable to leverage continuous physical degrees of freedom such as light polarization for co...

Thermal Aging of Aerospace Electro-Hydrostatic Actuator (EHA) Motor Insulation Systems

During the entire service cycle, the Electro-Hydrostatic Actuators (EHAs) are subjected to multi-physical stresses, including coupling effects, including high temperatures, severe temperature variation, and high-frequency pulses. These stresses not only act on the mechanical stru...

Electrochemical Cytosensor with Dual-Site Recognition Fabricated by In Situ Catalase-Encapsulated Metal–Organic Frameworks for Isolation and Detection of Circulating Tumor Cells in Whole Blood

Abstract Circulating tumor cells (CTCs) are critical biomarkers for cancer prognosis and treatment monitoring, yet their detection remains challenging due to low abundance and phenotypic heterogeneity. Herein, we developed a dual-aptamer-conjugated electrochemical cytosensor usin...

Self‐Assembled Mesoporous Nickel Polyphthalocyanine/Graphene Microspheres for Room‐Temperature Sensing of Carbonate Ester Leakage in Batteries

ABSTRACT The low viscosity of linear carbonate esters improves electrolyte wetting and ionic conductivity, making them essential for battery operation, but also rendering them prone to rapid evaporation when cells are mechanically damaged or leaking. Given their high flammability...

Verbal and nonverbal cues in influencer performance: a deep learning perspective on livestreaming e-commerce

Purpose Grounded in the elaboration likelihood model (ELM), this study aims to examine how influencer performance shapes sales outcomes in livestreaming e-commerce through the concurrent activation of the central route (verbal cues) and peripheral route (nonverbal cues), and how...

Playing with Fire, Losing the Drive: Bidirectional Links Between Problematic Smartphone Use and Grit Dimensions

This study examined bidirectional longitudinal associations between grit dimensions (consistency of interest [CI] and perseverance of effort [PE]) and problematic smartphone use (PSU) and tested cognitive flexibility as a mediating mechanism. A sample of 1,641 Chinese university...

Screening of ILs by COSMO ‐ RS and machine learning for extraction of n‐propanol/n‐propyl ether: Mechanism and process

Abstract N‐propyl ether (DPE) is produced via acid‐catalyzed dehydration of n‐propanol (NPA), forming a minimum‐boiling azeotrope. Conventional separation processes face challenges in both efficiency and product purity. In this work, a multi‐scale approach was employed to develop...

Data-Assisted Mechanical Balance Screening of and Candidate Window Identification for Starch/Halloysite Nanotube-Modified Cow Dung-Based Biodegradable Films

Agricultural waste-based biodegradable films are promising alternatives to polyethylene mulch films, but their use is limited by insufficient mechanical stability and the difficulty of balancing strength, ductility, and stiffness. In this study, cow dung-based biodegradable films...

A Tough, Room‐Temperature Curable and Economical Structural Adhesive Inspired by Luminescent Squid Skin

ABSTRACT Structural adhesives play a crucial role in achieving robust and intelligent bonding across diverse scenarios. However, the multi‐scenario bonding reliability and functionality of traditional epoxy adhesives remain constrained by their inherent brittleness, stress sensit...

Fatigue damage behavior and structural optimisation of asphalt concrete-reinforced subgrade in ballastless tracks under extreme climates

Abstract In cold regions, extreme cold and freeze–thaw cycles cause frost heave, layer separation, and fatigue cracks in high-speed railway ballastless tracks, posing a risk to the structure and safety. This study examines CRTS III tracks with full-scale fatigue tests at − 48 °C...
