Experimental and theoretical investigation of high-frequency electromagnetic noise generation in an electronic water pump

From experimental and theoretical perspectives, this paper investigates the generation mechanism of electromagnetic noise (EN) in an electronic water pump (EWP). A test-rig for EWP vibration and noise measurement is constructed, and powered-normal and motored tests are performed...

Ultrahigh strength enabled by dual-scale L12 precipitation and back-stress strengthening in an LPBF-fabricated (CoCrNi)94Al3Ti3 medium-entropy alloy

Simultaneously achieving ultrahigh strength and useful tensile ductility in precipitation-strengthened medium-entropy alloys requires control over not only precipitate characteristics but also the recovery and recrystallization of metastable additively manufactured microstructure...

Numerical Laminate Screening of Pin-Loaded CFRP Driveshaft Joints Using Progressive Damage Analysis and Multi-Criteria Evaluation

Carbon fiber-reinforced polymer (CFRP) driveshafts offer significant lightweight potential, but the performance of pin-loaded joints is strongly affected by laminate architecture. To support laminate selection beyond peak strength alone, a numerical screening framework combining...

Evidence Chain Selection and Cross-Domain Physical Context of a Durability-Sensitive Vibration Feature During a 300 h Diesel Engine Endurance Test

Long-duration diesel engine condition monitoring requires vibration descriptors that remain comparable over time despite path-dependent structural responses and physical measurements acquired on different schedules. A methodological need therefore remains for transparent multi-lo...

Interligand Energy Level Regulation for Fluorescence Modulation in Dual-Ligand Lanthanide Metal–Organic Frameworks

Lanthanide metal-organic frameworks (Ln-MOFs) have attracted great attention due to their unique antenna effect emission, while the introduction of dual ligands in Ln-MOFs could improve their performance significantly. Correspondingly, revealing the energy transfer mechanisms in...

Conditional Diffusion Model to Predict Structural Wind Loading Using Data from Sparse Sensors

Abstract Extreme local wind pressure causes damage to the envelopes and claddings of high-rise buildings. Accurate prediction of pressure time-series benefits the wind-resistance design and disaster precaution. The conditional diffusion model (CDM) is introduced to reconstruct ti...

Miniaturized Full-Stokes Spectrometers Based on Low-Correlation Metasurface Array

Abstract Full-Stokes spectrometers hold an immense application value due to their capability to simultaneously resolve polarization state and spectral information. Specifically, miniaturized full-Stokes spectrometers are promising for applications in real-world scenarios owing to...

Dynamic driver behavior modeling with GMM for sustainable traffic signal control in deep reinforcement learning

Adaptive traffic signal control is crucial for improving urban mobility and supporting environmental sustainability. Driver behavior heterogeneity has a significant impact on intersection performance, but its effective integration into reinforcement learning models remains challe...

Active wave compensation for dual-stage Stewart platforms using VAR-MPC

Ocean-wave-induced multi-degree-of-freedom disturbances degrade the motion-compensation accuracy and stability of shipborne offshore platforms. Although dual-stage Stewart platforms provide enhanced actuation capability, their performance is limited by inter-stage coupling, sensi...

Myelin-Inspired 3D PEGylation of Framework Nucleic Acids Enables Simultaneous Long Circulation and Rapid Renal Clearance

The rational design of nanomedicines is fundamentally constrained by a physicochemical paradox at the bio-nano interface: strategies to prolong circulation inevitably suppress clearance, often resulting in long-term accumulation and systemic toxicity. To address this, we propose...

Hydrogen‐Bonding‐Stabilized Organic Piezoelectric Nanofibers for Immunogenic Sonopiezodynamic Therapy of Metastatic Tumors

ABSTRACT Piezoelectric biomaterials enable mechano‐electrical coupling in biological systems, facilitating real‐time sensing, actuation, and in vivo energy harvesting. However, their application is constrained by the scarcity of stable organic piezoelectric systems. Here, we deve...

Checkerboard-type Zhang-Rice states in overdoped cuprate superconductors

Abstract Cuprate superconductors remain central to condensed matter physics due to their technological relevance and unconventional, incompletely understood electronic behavior. While the canonical phase diagram and low-energy models have been shaped largely by studies of underdo...

Achiral Additives Modulated Helicity and Supramolecular Fibrillation Assembly of Helical Dendronized Poly(phenylacetylene)s through Enhanced Radial Amphiphilicity †

Comprehensive Summary Non‐covalent interactions with additives have been demonstrated to be intriguing in conferring racemic polymers with preferential one‐handed helical conformation. However, these additives are normally chiral, and specific interactions are demanded. We report...

Unrestricted Phase Manipulation in Electrically Programmable Terahertz Metadevices via Dual-State Decoupling

Abstract Future terahertz (THz) paradigms, particularly in the context of 6G wireless networks and ubiquitous sensing, necessitate highly integrated and reconfigurable platforms capable of high-dimensional wavefront manipulation. However, the development of multifunctional THz me...

Joint fault prediction and remaining useful life estimation for large-scale mining equipment based on temporal convolutional network and multi-head self-attention

Abstract Reliable operation of large-scale mining equipment governs both production efficiency and the safety of the crews working underground, yet the maintenance strategies still common in the sector either replace healthy parts on a calendar or wait for a breakdown that arrive...

Microstructural Evolution and Through‐Thickness Mechanical Property Gradients in a 70‐mm‐Thick 316LN Stainless Steel Joint Produced by Narrow‐Gap Laser Welding With Pre‐Placed Filler Plates

Reliable joining of 70‐mm‐thick 316LN stainless steel is essential for fusion reactor applications. A high‐efficiency narrow‐gap laser welding strategy combining beam oscillation with pre‐placed filler plates was developed. A sound joint was produced in five passes, including one...

Shock–vortex interaction in transonic flow around a circular cylinder

Two-dimensional direct numerical simulations are performed to investigate shock–vortex interactions in transonic flow around a circular cylinder at R e D = 2000 and M a = 0.75 , 0.80, and 0.85. The wake-vortex evolution exhibits a quasi-periodic organization defined with referenc...

Revealing Non-Steady-State Structure–Performance Relationship in Plateau-Capacity-Dominated Hard Carbon Anodes for High-Rate Reversible Sodium Storage

Abstract The sodium storage structure–performance relationship of hard carbon anodes has long been regarded as an intrinsic material property and forms the basis for electrode design. This common view, however, does not hold with varying operating temperatures. At room temperatur...

Quantitative discrimination of debonding defects and non-debonding defects in coated propellant grain based on shearography

During the production of coated propellant grains, micro-bubble defects inevitably form within the liner layer. Although these non-debonding defects do not compromise structural integrity, current shearography-based non-destructive testing cannot reliably distinguish them from cr...
