AI‐Powered GPR Characterization of Peatland Underground Cavity Induced by Smoldering Wildfire: A Laboratory Proof‐of‐Concept

Safety Science and Technology, EarlyView.
We present an AI‐assisted ground‐penetrating radar framework to noninvasively detect and quantify smoldering wildfire‐induced subsurface cavities in peatlands. A ResNet model accurately predicts cavity geometry from GPR images, enabling improved assessment of underground fire damage and hazards.

Quantitative collagen and proteoglycan imaging reveal organic layering, gradients and regional texture in young mature dental cementum

VIEW, EarlyView.
Cementum, the mineralized tissue covering all mammalian tooth roots, helps maintain tooth stability, but its internal organization is still poorly understood. In this study, we combine quantitative histologial methods to map the regional distributions of collagen fibers and proteoglycan‐rich matrix layers in porcine cementum.

Blind Source Separation via Time‐Frequency Localization on Sound Spectrogram for Environmental Sound Source Attribution

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT As urban sound environments grow more complex, environmental monitoring increasingly demands not just sound‐level measurement but also source attribution. Current source recognition techniques can identify which sources are present in a mixture, but cannot measure each source's energy contribution, making accountability impossible.

Research on Ultra‐Wideband Pulse Current Method for DC Partial Discharge Measurement

High Voltage, EarlyView.
ABSTRACT The conventional pulse current method is commonly used in AC or DC withstand voltage tests with partial discharge (PD) monitoring. Because of its relatively narrow measurement bandwidth, this method tends to ignore critical information in PD waveforms, making it difficult to eliminate pulse‐type interference under DC voltage conditions, where ...

A femtosecond time‐resolved Bragg coherent diffraction imaging experimental setup at PAL‐XFEL for nanoscale lattice dynamics studies

Journal of Synchrotron Radiation, EarlyView.
The XSS beamline at PAL‐XFEL provides a femtosecond time‐resolved Bragg coherent X‐ray diffraction imaging setup, optimized for tracking transient lattice dynamics and nanoscale strain fields within single crystals during dynamic processes.We report on the design and operational characterization of a femtosecond time‐resolved Bragg coherent X‐ray ...
