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...

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...

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...

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...
