An Effective Method for Islanding Detection Based on Variational Mode Decomposition

open access: yesElectrica, 2019
The present study presents a new islandingdetection method based on variational mode decomposition (VMD). In the method,the VMD transform of the voltage at point of common coupling is calculated, andthen based on the decomposed modes, an islanding ...

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

A secured, reliable and accurate unplanned island detection method in a renewable energy based microgrid

open access: yesEngineering Science and Technology, an International Journal, 2021
The paper proposes an unplanned island detection method in a microgrid with micro phasor measurement unit (μPMU). The μPMU extracts certain features, by using multi domain nature of discrete fractional Fourier transform, from measured voltage data and ...

Implementation and Evaluation of a Cooperative Vehicle-to-Pedestrian Safety Application

open access: yes, 2017
While the development of Vehicle-to-Vehicle (V2V) safety applications based on Dedicated Short-Range Communications (DSRC) has been extensively undergoing standardization for more than a decade, such applications are extremely missing for Vulnerable Road

High resolution imaging with Fresnel interferometric arrays: suitability for exoplanet detection [PDF]

open access: yes, 2005
We propose a new kind of interferometric array that yields images of high dynamic range and large field. The numerous individual apertures in this array form a pattern related to a Fresnel zone plate. This array can be used for astrophysical imaging over

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

open access: yesFEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.
