A Novel Digital Twin Platform for Accelerating Power Systems Restoration

open access: yesEnergy Internet, EarlyView.
Hardware Architecture Design of DT System in Laboratory. ABSTRACT With the global energy structure transforming towards the goal of net zero emissions, the penetration of an inverter‐based resource (IBR) in power systems is increasing. This transformation poses two critical challenges: the system post blackout restoration process becomes extremely ...

Stability Analysis and Improvement Mechanism of Grid‐Forming Converter Connected to a Low‐Impedance Grid

open access: yesHigh Voltage, EarlyView.
ABSTRACT This paper investigates the stability and improvement mechanisms of a grid‐forming (GFM) converter connected to a low‐impedance grid. Initially, a state‐space model of the GFM converter integrated into an AC grid is developed for stability analysis.

Grid-connected converter with grid-forming and grid-following modes presenting symmetrical and asymmetrical fault ride-throug capability [PDF]

open access: yes
Grid-connected converters must remain coupled to the grid during a fault. They have to control the reactive currents injected to the grid because of its limited overload capacity. In particular, grid-forming (GFM) converters ride through the fault either

PanGraphRNA: An efficient and flexible bioinformatics platform for graph pangenome‐based RNA‐seq data analysis

open access: yesJournal of Integrative Plant Biology, Volume 68, Issue 7, Page 2001-2017, July 2026.
PanGraphRNA is an easy‐to‐use platform that improves RNA‐seq analysis by using graph pangenomes instead of a single reference genome. It increases read alignment accuracy, detects important genes missed by traditional methods, and works across major crops, helping researchers obtain more reliable transcriptome results for diverse plant research and ...

Interrelations of aortic spring function, cardiovascular disease risk factors, and left ventricular diastolic function: The Framingham Heart Study

open access: yesPhysiological Reports, Volume 14, Issue 13, July 2026.
Abstract Mechanical twisting and untwisting of the left ventricle as well as abnormal hemodynamic aortic‐ventricular coupling are recognized as contributors to left ventricular diastolic function. However, energy associated with proximal aortic stretch during systole can be recovered as diastolic elastic recoil that may facilitate diastolic left ...
