Intelligent Retrieval of Corresponding Engineering Standard Clauses for Cross-Border Construction Projects

Cross-border construction projects increasingly involve heterogeneous engineering standards from different national systems, creating challenges for standards comparison and compliance assessment. Existing approaches largely rely on textual similarity or syntactic matching, which...

High‐Rate Magnesium‐Ion Batteries Enabled by Boron‐Doped Bismuth Anodes

Large volume expansion upon (de)alloying faced by bismuth anodes always leads to severe capacity loss and poor durability for magnesium‐ion batteries. This failure mode becomes particularly pronounced under high current‐density impact, where the sluggish electron transport and io...

Seismic behavior of circular steel tube confined reinforced concrete column-steel beam frames considering the joint effect

Reliable beam-column joints and rational design methods are crucial to ensure the safety and economy of frames, particularly for steel-concrete composite structures. This study numerically investigates the seismic behavior of the frame consisting of circular steel tube confined r...

On the converse of the Shimorin–Peláez–Rättyä–Wick theorem

Abstract We establish a converse of the Shimorin–Peláez–Rättyä–Wick theorem. Indeed, we obtain necessary and sufficient conditions for a Shimorin-type kernel to be the kernel of a radial, logarithmically subharmonic weighted Bergman space.

Thermal–hydraulic design and multi-objective optimisation of a cicada-wing-vein-inspired liquid cooling plate for lithium-ion battery thermal management

To improve the thermal safety and temperature uniformity of lithium-ion batteries under high-rate discharge, a cicada-wing-vein-inspired liquid cooling plate with hierarchical branching and lateral interconnections was developed. Three channel configurations, including rectangula...

Flexible PVDF-HFP Piezoelectric Nanofibers with In Situ rGO and BCZT for High-Sensitivity Tactile Sensing and Haptic-Visual Feedback

Abstract Flexible polymer-based piezoelectric sensors are promising for electronic skin and human–machine interfaces, but challenges remain in achieving efficient electromechanical conversion and sensitive low-pressure detection due to insufficient polarization and weak interfaci...

A Meta‐Action‐Oriented Reliability Allocation for Machine Tools Using Bayesian Networks and Fuzzy Set Theory

ABSTRACT The rationality of reliability allocation is critical to improving the inherent reliability of machine tools. However, under fuzzy environments, traditional methods struggle to effectively characterize multi‐source uncertainties, leading to deviations between allocated a...

A fully-enclosed torsional galloping electromagnetic wind energy harvester

Most galloping wind energy harvesters (WEHs) are based on transverse galloping, whereas very few utilize torsional galloping. Adopting a fully-enclosed structure to protect components vulnerable to harsh external environmental conditions can improve the stability and reliability...

Real-World Driving CO2 Emissions and Engine Thermal Efficiency Evaluation of Hybrid Vehicles: A Regression-Based Parameter Identification Approach

Real-world driving tests reflect vehicle performance in everyday use, but extracting energy conversion data from extensive measurements remains challenging. The study compared a hybrid electric vehicle and a plug-in hybrid electric vehicle, with the latter operated in charge-sust...

Synergistic co-intercalation of binary and ternary transition-metal cations in hydrated vanadium oxide nanosheets for high-performance aqueous zinc-ion batteries

Vanadium-based oxides have emerged as promising cathode materials in aqueous zinc-ion batteries (AZIBs), owing to their tunable layered architectures and high theoretical specific capacities. To date, hydrothermal/solvothermal synthesis remains the predominant approach for prepar...

Monodentate Acetate-Coordinated Electrolyte for Accelerated Zn2+ Desolvation and Stable Zinc Anodes

Abstract Aqueous zinc-ion batteries (AZIBs) are promising candidates for large-scale energy storage, but their practical deployment is hindered by dendrite growth and water-induced side reactions. These challenges mainly arise from the high desolvation barrier of [Zn(H2O)6]2+, wh...

Transient Electric Field Evolution in a 220 kV Cable Joint Under Switching Overvoltage Considering Measured Dielectric Dispersion

Switching energization imposes wideband transient voltages on cable joints, whereas conventional simulations often use frequency-independent properties for semiconductive field-control components. This study develops a measurement-informed time-domain workflow for a 220 kV cable...

DinoDental : Benchmarking DINOv3 as a Unified Vision Encoder for Dental Image Analysis
