Revealing Dust Source Changes in East Asia From Past to Future: An Interpretable Deep Learning Approach

Land Degradation &Development, EarlyView.
ABSTRACT Aeolian dust source areas are controlled by climate and human activities and are closely associated with land degradation, yet their long‐term evolution under global warming remains insufficiently quantified. An integrated framework that couples a U‐Net segmentation model with Shapley Additive Explanations (SHAP) was built to map and attribute

Analysis of Mechanical‐Electrical‐Hydraulic Coupled Vibration Response Characteristics of Thermal Control Circulating Pumps Supported by Water‐Lubricated Bearings

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The operational reliability of thermal control circulation pumps is significantly restricted by the multi‐physics coupled environment. To reveal the vibration transmission mechanisms and dynamic response characteristics under multi‐field coupled excitations, a multi‐DOF coupled dynamic representation of the overall system, incorporating the ...

In Situ Crystallization‐Induced Coherent Interfaces for Simultaneous Toughening and Hardening of Reinforced Silicon Carbide Nanoceramic

National Materials, EarlyView.
This work reports the fast hot‐pressing sintering of precursor‐derived amorphous SiC raw powders to prepare HfC‐reinforced SiC nanoceramic with coherent HfC/SiC interfaces. Through the synergistic effects of nanocrystallization strengthening and interface engineering, the simultaneous enhancement of three typically competing mechanical properties, that

A Two‐Stage Optimization Approach for Selecting Electric‐Flight Airports

Networks, EarlyView.
ABSTRACT The decarbonization of short‐haul air transport has gained increasing attention, with electric aircraft emerging as a promising alternative to conventional short‐haul aviation. However, given the substantial investment anticipated for the necessary infrastructure, a strategic and globally coordinated selection of airports is imperative.

Mechanical and Impact Response of Adhesively Bonded ASA/PA12 Sandwich Structures Produced by Fused Filament Fabrication

Polymer Engineering &Science, EarlyView.
Adhesively bonded ASA/PA12 FFF sandwich structures reveal that interfacial compliance governs mechanical performance. Cyanoacrylate enhances strength but induces brittle failure, while polyurethane improves ductility and impact resistance, demonstrating that adhesive properties and stacking sequence are critical design parameters for optimizing multi ...

Design and Development of a Modular Ballistic Pendulum for High‐Impulse Measurement in Contact and Near‐Field Explosive Loading

Propellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT Measuring impulse from explosive charges in contact and near‐field configurations presents practical challenges due to wide variation in impulse magnitude. Ballistic pendula are widely used for impulse measurement, but many existing designs are limited to narrow operating envelopes or are poorly suited to repeated contact testing and tamped ...
