Phase Transition Mediated Solvation Structure Regulation in Quasi‐Solid‐State Composite Electrolyte for High‐Voltage Sodium Batteries

ABSTRACT Quasi‐solid‐state composite electrolytes (QSSEs) represent a promising approach to fabricating high‐energy rechargeable batteries, but their practical implementation is hindered by structural instability and interfacial incompatibility. In this study, a QSSE was prepared...

Achieving simultaneous strength-ductility-corrosion optimization of solid-state additive friction stir deposited superlight Mg-Li alloy by a hybrid high flow rate Argon/CO₂ shielding atmosphere

High-performance Mg–Li alloys were fabricated via solid-state additive friction stir deposition under a mixed Ar/liquid CO₂ atmosphere, which addresses severe oxidation and unfavorable thermal cycling issues during additive manufacturing. Benefiting from optimized microstructures...

Research and Field Test of Autonomous Underwater Vehicles Cooperative‐Navigation Method in Terrain Mapping

ABSTRACT A cooperative‐navigation algorithm based on an extended Kalman filter (EKF) is proposed for Leader–Follower autonomous underwater vehicles (AUVs) to address inconsistencies in inter‐vehicle navigation coordinate systems caused by the absence of geo‐referencing signals in...

Systematic Screening of Depression-Related Neurotoxicity Across 26 Bisphenols Reveals an ESR1–CREB1–GRIN2B-Associated Mechanism

Bisphenols (BPs) are widespread environmental endocrine disruptors, but their potential depression-related neurotoxicity has not been systematically assessed. Here, we combined machine learning (ML), network toxicology, molecular docking, and in vivo experiments to screen 26 bisp...

Influence of Bilateral WIG Effect on Oscillating Hydrofoil Energy Harvesting Performance and Experimental Suggestions

The oscillating hydrofoil represents a promising tidal energy harvesting device, but its hydrodynamic behavior and energy harvesting performance can be significantly affected by the wing-in-ground (WIG) effect under near-wall conditions. The present work establishes a two-dimensi...

Analysis of Rotor Vibration Characteristics in an Active Magnetic Suspension Flywheel Energy Storage System Considering the Unbalanced Magnetic Pull Force of the Motor

A flywheel energy storage system (FESS) is a device that employs a high-speed rotating flywheel for energy storage, where the motor is a core component enabling the energy conversion. Since the motor rotor is integrated onto the flywheel rotor (FR), when the FESS operates, the vo...

A causal evidential reasoning rule-based method for concrete compressive strength prediction

Concrete compressive strength is a key indicator for measuring structural performance and durability. Its accurate prediction is essential for engineering safety and construction quality. However, concrete strength is influenced by many material and environmental factors, making...

Performance evaluation of an axial-flow gas turbine compressor using methanol droplets as the cooling medium

This study employs ANSYS CFX to analyze wet compression technology in the NASA Stage 35 axial compressor. A primary challenge of wet compression is the risk of blade erosion caused by slow-evaporating or poorly atomized droplets. To mitigate this, methanol was selected as the eva...

AIE: Adaptive Inter-Domain Ensemble for Boosting Cross-Domain Audio Adversarial Transferability

Deep neural networks are vulnerable and susceptible to adversarial attacks. Audio adversarial examples impose acoustically imperceptible perturbations to clean audio examples, fooling classification models into producing incorrect results. Transferability is a critical property o...

RL-Augmented Dual Robust Adaptive Propagated Interval Observer for Actuator and Residual-Framed Sensor Fault Detection and Isolation in Underactuated AUVs

Reliable fault detection and isolation (FDI) for actuators and sensors in underactuated autonomous underwater vehicles (AUVs) is challenging because nonlinear hydrodynamic coupling redistributes fault signatures, and persistent ocean currents can trigger false alarms. This paper...
