Research on Inrush Current Suppression of Transformer Based on Changeable Closing Angle

Zhongguo dianli, 2022
The transformer no-load closing inrush current may cause safety problems in power grid, and the controlled switching technology with fixed target angle still has room for improvement in suppressing inrush current. A transformer inrush current suppression

Networks of Coevolving Residues in Voltage Sensor Domains [PDF]

Biophysical Journal, 2014
Voltage sensors (VSDs) are ubiquitous protein domains acting as transducers of transmembrane electric signals. Owing to the fundamental nature of this task, VSDs emerged before the division between prokaryotes and eukaryotes and are accordingly found in extant genes from long-diverged phylogenetic lineages.

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Mapping of residues forming the voltage sensor of the voltage-dependent anion-selective channel. [PDF]

Proceedings of the National Academy of Sciences, 1993
Voltage-gated ion-channel proteins contain "voltage-sensing" domains that drive the conformational transitions between open and closed states in response to changes in transmembrane voltage. We have used site-directed mutagenesis to identify residues affecting the voltage sensitivity of a mitochondrial channel, the voltage-dependent anion-selective ...

Charging and discharging phenomena in electrostatically-driven single-crystal-silicon MEM resonators: DC bias dependence and influence on the series resonance frequency [PDF]

, 2008
This paper presents a first study concerned with charging and discharging phenomena in single crystal silicon MEM resonators. It is shown that the DC voltage required for the device operation induces a residual voltage between the resonator and its ...

Voltage and Current Sensor Fault Diagnosis Method for Traction Converter with Two Stator Current Sensors

Sensors, 2022
The traction converter is one of the key components of high-speed trains. Current and voltage sensor faults in the converter may lead to feedback values deviation and system degradation, which will bring security risks to the train. This paper proposes a
