Intermediate state trapping of a voltage sensor [PDF]

Journal of General Physiology, 2012
Voltage sensor domains (VSDs) regulate ion channels and enzymes by undergoing conformational changes depending on membrane electrical signals. The molecular mechanisms underlying the VSD transitions are not fully understood. Here, we show that some mutations of I241 in the S1 segment of the Shaker Kv channel positively shift the voltage dependence of ...

Generator voltage droop and voltage-reactive states of transmission network [PDF]

Zbornik radova, Elektrotehnicki institut Nikola Tesla, 2012
This paper examines the impact of generator voltage droop to the voltage-reactive states of transmission networks. First, voltage droop definition is given, as well as its measurement procedure and setting. Models of incorporating generator voltage droop into an analysis of static and dynamic states are given.

Steady state voltage stability with AVR voltage constraints

International Journal of Electrical Power & Energy Systems, 2012
Abstract Voltage collapse phenomena are highly affected by the limits of Automatic Voltage Regulator (AVR) voltage that indirectly controls the amount of reactive power generation. Saturation of the limits of the AVR voltage of a unit may result in deterioration of voltage stability.

Density of states and current–voltage characteristics in SIsFS junctions [PDF]

Superconductor Science and Technology, 2021
Abstract We study the density of states (DOS) inside superconducting Josephson SIsFS junctions with complex interlayer consisting of a thin superconducting spacer ’s’ between insulator I and a ferromagnetic metal F.

Metastable voltage states of coupled Josephson junctions

Physical Review B, 1997
We investigate a chain of capacitively coupled Josephson junctions in the regime where the charging energy dominates over the Josephson coupling, exploiting the analogy between this system and a multi-dimensional crystal. We find that the current-voltage characteristic of the current-driven chain has a staircase shape, beginning with an (insulating ...

Role of Voltage Control Devices in Low Voltage State Estimation Process

International Transactions on Electrical Energy Systems, 2023
Megatrends, such as the proliferation of distributed generation, electrification, and the appearance of aggregator companies, put the low voltage power grids under intense pressure. Since the network infrastructure developments cannot keep up with the trends, distribution system operators turned to alternative solutions.

Voltage Sensor Trapping in the Relaxed State [PDF]

Biophysical Journal, 2013
The voltage sensitive phosphatase from Ciona intestinalis (Ci-VSP) has constituted an intriguing model for the study of the dynamic of voltage sensing domains (VSD). Four of the five arginines in the fourth (S4) segment of the VSD function as charges sensing the difference in electrical potential across the membrane.

State Feedback Reshaping Control of Voltage Source Converter

IEEE Transactions on Power Electronics, 2022
Admittance reshaping is a widely used strategy to address the converters low-frequency stability issues in weak grid, caused by the PLL and its interaction with the dc and ac voltage controls. However, the asymmetric control of the d-and q-axis current references and the coupling between the converter ac and dc sides restricts the damping capability of

Carcinomas and Carcinoid Tumors of the Lungs and Bronchi in Children and Adolescents: The EXPeRT Recommendations

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Primary lung carcinomas and bronchial carcinoid tumors (BC) are very rare malignancies in childhood. While typical BC and mucoepidermoid carcinomas are mostly low‐grade, localized tumors with a more favorable prognosis than in adults, necessitating avoidance of overtreatment, adenocarcinomas of the lung are often diagnosed at advanced disease ...
