Distribution Transformer Voltage Control Using a Single-Phase Matrix Converter [PDF]

open access: yes, 2022
A new topology is proposed for fully-electronic tap changers in distribution transformers. In every single phase, the voltage is regulated by a 2x1 matrix converter, which can be extended using the concept of multilevel converters.

Modelling stem cell differentiation related processes—A practical overview for biologists

open access: yesFEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Three-phase UPS transformer using stand-by inverter of a single cores

open access: yes, 1981
A new three-phase UPS transformer for an uninterruptible power supply (UPS) is described. Its configuration is a magnetic integration of a three-phase ferroresonant transformer and a single- to three-phase converter.

Real Time Measurement of Average Winding Resistances of Transformers

open access: yesGazi Üniversitesi Fen Bilimleri Dergisi, 2018
The monitoring of transformers that are expensive equipment of power systems is the one of important issues. Transformer monitoring systems are usually used in order to detect failures, to determine the lifetime, to measure losses and to monitor winding

Identification of a Shiga toxin A‐derived peptide internalized into Gb3 receptor‐bearing cells via interaction with the Shiga toxin B subunit

open access: yesFEBS Letters, EarlyView.
The process of internalization of the Shiga toxin A subunit via formation of a complex with the Shiga toxin B subunit, which specifically binds to the Gb3 receptor. The peptide is designed to act as a carrier of drugs into cancer cells. Here, we explored the potential of peptides derived from the catalytic A subunit of Shiga toxin (STxA) to be drug ...

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions

open access: yesFEBS Letters, EarlyView.
The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.
