Dynamic Voltage Restorer to Mitigate Voltage Sag/Swell using Black Widow Optimization Technique with FOPID Controller

open access: yesEAI Endorsed Transactions on Energy Web, 2023
The efficiency with which electrical equipment use electricity is essential for several reasons. First, superior power quality (PQ) improves efficiency and facilitates peak performance in electronic equipment.

A new voltage control strategy to improve performance of DSTATCOM in electric grid

open access: yesCES Transactions on Electrical Machines and Systems, 2020
A new voltage control strategy of distribution static compensator (DSTATCOM) has been proposed in this paper for electric grid applications. The proposed control scheme combines two methods of DSTATCOM operation to improve its performance.

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

open access: yesFEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Sparse Linear Models applied to Power Quality Disturbance Classification

open access: yes, 2015
Power quality (PQ) analysis describes the non-pure electric signals that are usually present in electric power systems. The automatic recognition of PQ disturbances can be seen as a pattern recognition problem, in which different types of waveform ...

Cell wall target fragment discovery using a low‐cost, minimal fragment library

open access: yesFEBS Letters, EarlyView.
LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

Influence of environmental changes on power quality disturbances in Hybrid Renewable Energy System

open access: yesEnergy Reports, 2023
Environmental changes profoundly affect PQ disturbances in Hybrid Renewal Energy Systems (HRES). The stand-alone hybrid renewable energy system is increasing its share of the energy sector.

CDK11 inhibition induces cytoplasmic p21WAF1 splice variant by p53 stabilisation and SF3B1 inactivation

open access: yesMolecular Oncology, EarlyView.
CDK11 inhibition stabilises the tumour suppressor p53 and triggers the production of an alternative p21WAF1 splice variant p21L, through the inactivation of the spliceosomal protein SF3B1. Unlike the canonical p21WAF1 protein, p21L is localised in the cytoplasm and has reduced cell cycle‐blocking activity.

New switching approach for DVR using one cycle control method

open access: yesAin Shams Engineering Journal, 2018
One of the effective devices to eliminate voltage disturbances of sensitive loads in distribution systems is dynamic voltage restorer (DVR). In previous studies, the sinusoidal pulse width modulation (SPWM) method has been used as a switching method for ...
