A Single-Phase Quasi Z-Source Dynamic Voltage Restorer(DVR) [PDF]

The Transactions of the Korean Institute of Power Electronics, 2010
This paper deals with a single-phase dynamic voltage restorer(DVR) with a quasi Z-source topology. The proposed system based on a single-phase quasi Z-source PWM ac-ac converter which have features such as the input voltage and output voltage are sharing ground, and input current operates in continuous current mode(CCM).

A Hybrid Semi‐Inverse Variational and Machine Learning Approach for the Schrödinger Equation

Advanced Physics Research, Volume 5, Issue 6, June 2026.
A hybrid semi‐inverse variational and machine‐learning framework is presented for solving the Schrödinger equation with complex quantum potentials. Physics‐based variational solutions generate high‐quality training data, enabling Random Forest and Neural Network models to deliver near‐perfect energy predictions.

Artificial gravity during prolonged bed rest preserves resting metabolic rate but not muscle function: Evidence from the BRACE study

The Journal of Physiology, Volume 604, Issue 12, Page 4771-4794, 15 June 2026.
Abstract figure legend This study examined whether supine cycling exercise, with or without artificial gravity, preserves resting metabolic rate (RMR) during 60 days of head‐down tilt bed rest, and whether RMR responses align with integrated multivariate physiological adaptations.

Metabolic Reprogramming Analysis of Wheat Response to Low Temperature Stress Under Nitrogen Supply

Food and Energy Security, Volume 15, Issue 3, May/June 2026.
Low temperature stress triggers a defense network that maintains growth at the expense of inhibiting photosynthesis and chlorophyll synthesis. Temperature recovery effectively repairs low temperature‐induced damage and enhances stress resistance, while nitrogen supply can further augment these protective processes to strengthen cold tolerance ...

A Tutorial on Bayesian Multi‐Study Factor Analysis With Applications in Nutrition and Genomics

Statistics in Medicine, Volume 45, Issue 10-12, May 2026.
ABSTRACT High‐dimensional data are crucial in biomedical research. Integrating such data from multiple studies is a critical process that relies on the choice of advanced statistical models, enhancing statistical power, reproducibility, and scientific insight compared to analyzing each study separately.

Mechanism and Control Analysis of Synchronous Frequency Resonance in Distributed Power Generation System Connected to Grid

Energy Science &Engineering, Volume 14, Issue 4, Page 2263-2276, April 2026.
Small‐signal modeling reveals that insufficient system damping positions conjugate poles near the imaginary axis, fundamentally explaining the SFR mechanism. A virtual resistance control is consequently proposed to damp the resonance and effectively suppress SFR, which is validated through Hardware‐in‐the‐Loop experiments.
