Gold Nanoparticle‐Catalyzed Solvent Switchable Selective Partial Reduction of Nitrobenzene to N‐Phenylhydroxylamine and Azoxybenzene

ChemCatChem, Volume 17, Issue 5, March 6, 2025.
Phosphine and phosphine oxide‐decorated polymer‐immobilized ionic liquid stabilized AuNPs are highly selective catalysts for the solvent‐dependent partial reduction of nitrobenzene to N‐phenylhydroxylamine in water and azoxybenzene in ethanol. Catalysts generated from phosphine oxide‐decorated support impregnated with either Au(I) or Au(III) are ...

Fluctuation Analyses for Pattern Classification in Nondestructive Materials Inspection

EURASIP Journal on Advances in Signal Processing, 2010
We review recent work on the application of fluctuation analyses of time series for pattern classification in nondestructive materials inspection. These analyses are based on the evaluation of time-series fluctuations across time intervals of increasing ...

Evaluating Near‐Surface Wind Speeds Simulated by the CRCM6‐GEM5 Model Using AmeriFlux Data Over North America

Journal of Advances in Modeling Earth Systems, Volume 17, Issue 3, March 2025.
Abstract We evaluate the performance of various configurations of the Canadian Regional Climate Model (CRCM6‐GEM5) in simulating 10‐m wind speeds using data from 27 AmeriFlux stations across North America. The assessment employs a hierarchy of error metrics, ranging from simple mean bias to advanced metrics that account for the dependence of wind ...

Segmenting hydrogen‐induced cracking defects in steel through scanning acoustic microscopy and deep neural networks

Engineering Reports, Volume 6, Issue 12, December 2024.
This research employs the YOLOv8‐seg deep learning model to identify and segment hydrogen‐induced cracking (HIC) in steel through B‐scan images obtained via Scanning Acoustic Microscopy (SAM), achieving a mean Average Precision (mAP) score better than 0.95.

A multimodal expert system for the intelligent monitoring and maintenance of transformers enhanced by multimodal language large model fine‐tuning and digital twins

IET Collaborative Intelligent Manufacturing, Volume 6, Issue 4, December 2024.
(1) An intelligent monitoring and maintenance digital twin multimodal expert reasoning system, fine‐tuned on visual language‐based large models, is proposed. (2) This system not only achieves real‐time monitoring of the transformer's operational status but also generates maintenance strategies intelligently based on operational conditions.

Scale‐ and Variable‐Dependent Localization for 3DEnVar Data Assimilation in the Rapid Refresh Forecast System

Journal of Advances in Modeling Earth Systems, Volume 16, Issue 11, November 2024.
Abstract This study demonstrates the advantages of scale‐ and variable‐dependent localization (SDL and VDL) on three‐dimensional ensemble variational data assimilation of the hourly‐updated high‐resolution regional forecast system, the Rapid Refresh Forecast System (RRFS).

Orographic gravity‐wave drag over multiple bell‐shaped mountains

Quarterly Journal of the Royal Meteorological Society, Volume 150, Issue 761, Page 2397-2417, April 2024 Part B.
Mountains exert a drag on the atmospheric flow through breaking gravity waves, known as orographic gravity‐wave drag (OGWD). We derive OGWD analytically for multiple three‐dimensional bell‐shaped mountains, while previous studies have derived OGWD for a single mountain. We take into account the geometric overlap between the mountains, vertical shear of

ECMWF and UK Met Office Offshore Blowing Winds: Impact of Horizontal Resolution and Coastal Orography

Journal of Geophysical Research: Atmospheres, Volume 129, Issue 6, 28 March 2024.
Abstract We analyze the performance of the European Centre for Medium‐Range Weather Forecasts (ECMWF) and UK Met Office (UKMO) meteorological models in predicting offshore blowing wind in coastal areas. Our attention is mainly on the Mediterranean coast, up to 200 km distance from the shore. We compare forecast neutral winds with Advanced Scatterometer
