Stabilized h-BN release layer on PVD-AlN/sapphire template for high-performance GaN-based flexible weak-light photodetectors

Layered hexagonal boron nitride (h-BN) enables the release and transfer of III-nitride epilayers toward flexible electronics, but its insufficient interfacial adhesion to the substrate would limit its compatibility with conventional fabrication processes. Here, based on a sapphir...

Multiple Pickering Emulsions Enable Highly Efficient Interfacial Catalysis and Extracellular Vesicle Classification via In Situ Surface-Enhanced Raman Spectroscopy

Abstract Multiple Pickering emulsions show great potential in catalysis and bioanalysis but remain limited by insufficient structural stability, unclear interfacial mechanisms, and limited functional integration. Here, a stable water-in-oil-in-water multicompartment Pickering emu...

Addressing Span Imbalance and Semantic Complexity in Nested Medical Named Entity Recognition

As a fundamental task in biomedical natural language processing, Medical Named Entity Recognition (MNER) aims to identify and classify medical entities from unstructured medical texts. A major challenge in this task is the prevalence of nested entities, which arise from the synta...

Passive Metasurface Tweezers for Multi‐Scale Orbital Transport and Trapping on Elastic Plates

ABSTRACT Acoustic manipulation on solid surfacesis often constrained by limited wave‐field reconfigurability and reliance on complex active excitation, hindering the simultaneous realization of particle confinement and controlled rotation. Here, we present a passive, subwavelengt...

Transient phase-based faulty feeder identification for high-impedance faults via autocorrelation entropy difference

In resonant grounding distribution systems (RGDSs), high-impedance faults (HIFs) generate severely attenuated currents and complex arcing behaviors, making faulty feeder identification particularly challenging. Existing magnitude-based methods suffer from significant performance...

Flow-particle coupling characteristics and parameter optimization of a dual-jet hydraulic collector based on Box-Behnken design

The deep-sea floor abounds with polymetallic nodules, effective exploitation of these nodules can alleviate the pressure of terrestrial resource depletion and meet industrial demands. As one of the high-efficiency hydraulic collection approaches, dual-jet technology has been wide...

Model Inversion Attacks Through Target-Specific Conditional Diffusion Models

Model inversion attacks (MIAs) aim to reconstruct private images from a target classifier's training set, thereby raising privacy concerns in AI applications. Previous GAN-based MIAs tend to suffer from inferior generative fidelity due to GANs’ inherent flaws and biased optimizat...

Effect of beam diameter on microstructure evolution and corrosion resistance of laser-cladded high-chromium nickel based alloy coatings

Laser cladding has been widely employed for surface modification and repair of structural components exposed to corrosive environments. In this study, high-chromium nickel-based alloy coatings were fabricated using three coupled, beam-diameter-dependent parameter sets. Laser powe...

Decomposition of phengite from residual subducted slabs enhancing lithospheric tin mineralization: Insights from K–Li–Nd isotopes
