A Novel ANN-PSO Method for Optimizing a Small-Signal Equivalent Model of a Dual-Field-Plate GaN HEMT.
Micromachines (Basel)
November 2024
Innovation Center for Electronic Design Automation Technology, Hangzhou Dianzi University, Hangzhou 310018, China.
This study introduces a novel method that integrates artificial neural networks (ANNs) with the Particle Swarm Optimization (PSO) algorithm to enhance the efficiency and precision of parameter optimization for the small-signal equivalent model of dual-field-plate GaN HEMT devices. We initially train an ANN model to predict the S-parameters of the device, and subsequently utilize the PSO algorithm for parameter optimization. Comparative analysis with the NSGA2 and DE algorithms, based on convergence speed and accuracy, underscores the superiority of the PSO algorithm.

J Clin Exp Hepatol
November 2024
Department of Nephrology, Post Graduate Institute of Medical Education and Research, Chandigarh, India.
Background: Renal impairment significantly affects morbidity and mortality rates of cirrhosis patients. Studies on glomerular filtration rate (eGFR) estimation did not include cirrhosis patients. These equations are erroneous and unreliable in cirrhosis due to sarcopenia.

Eur J Radiol Open
June 2025
Institution of Molecular Medicine and Surgery (MMK), Karolinska Institutet, Stockholm, Sweden.
Background: High-quality assessment of prostate MRI is fundamental in both clinical practice and screening. There is a lack of national level data on variability in prostate volume measurement and PI-RADS assessment. Methods of quality assurance need to be developed.

Article Synopsis
- Differentiating between ventricular tachycardia (VT) and supraventricular wide tachycardia (SWCT) using 12-lead ECG is challenging and has traditionally depended on manual interpretation, which can be limited by the user's expertise.
- Recent research has introduced automated algorithms that may offer improved accuracy over manual methods, but there has been little direct comparison between these two approaches.
- A study by LoCoco et al. (2024) evaluated the effectiveness of traditional manual ECG differentiation methods against five automated algorithms, analyzing 213 ECGs to assess their diagnostic performance.
Prediction of Retention Indices in LC-HRMS for Enhanced Structural Identification of Organic Micropollutants in Water: Selectivity-Based Filtration.
Anal Chem
January 2025
Separation Science Group, Department of Organic and Macromolecular Chemistry, Ghent University, Krijgslaan 281 S4bis, B-9000 Ghent, Belgium.
Addressing the global challenge of ensuring access to safe drinking water, especially in developing countries, demands cost-effective, eco-friendly, and readily available technologies. The persistence, toxicity, and bioaccumulation potential of organic pollutants arising from various human activities pose substantial hurdles. While high-performance liquid chromatography coupled with high-resolution mass spectrometry (HPLC-HRMS) is a widely utilized technique for identifying pollutants in water, the multitude of structures for a single elemental composition complicates structural identification.
