Impedance Modeling and SSR Analysis of DFIG Using Complex Vector Theory

IEEE Access, 2019
Based on the complex vector theory, a more comprehensive doubly-fed induction generator (DFIG) impedance model under series compensated network, taking both outer loops and phase-locked loop (PLL) dynamic into consideration, is developed in stationary ...

Functional Connectivity Linked to Cognitive Recovery After Minor Stroke

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Patients with minor stroke exhibit slowed processing speed and generalized alterations in functional connectivity involving frontoparietal cortex (FPC). The pattern of connectivity evolves over time. In this study, we examine the relationship of functional connectivity patterns to cognitive performance, to determine ...

A Method for the Realization of an Interruption Generator Based on Voltage Source Converters

Energies, 2017
In this paper we described the structure and working principle of an interruption generator based on voltage source converters (VSCs). The main circuit parameters of the VSCs are determined according to the target of power transfer capability, harmonic ...

More on complexity of operators in quantum field theory [PDF]

, 2019
Recently it has been shown that the complexity of SU($n$) operator is determined by the geodesic length in a bi-invariant Finsler geometry, which is constrained by some symmetries of quantum field theory.

Discovery and Targeted Proteomic Studies Reveal Striatal Markers Validated for Huntington's Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Clinical trials for Huntington's disease (HD) enrolling persons before clinical motor diagnosis (CMD) lack validated biomarkers. This study aimed to conduct an unbiased discovery analysis and a targeted examination of proteomic biomarkers scrutinized by clinical validation. Methods Cerebrospinal fluid was obtained from PREDICT‐HD and

Information flow through a model of the C. elegans klinotaxis circuit

, 2015
Understanding how information about external stimuli is transformed into behavior is one of the central goals of neuroscience. Here we characterize the information flow through a complete sensorimotor circuit: from stimulus, to sensory neurons, to ...

On mathematical model and equivalent circuit of transformer (critical analysis of generally accepted theory)

Vestnik of Astrakhan State Technical University. Series: Marine engineering and technologies, 2023
The article considers the importance of studying the mathematical model and equivalent circuit of the transformer due to the fact that transformers are the most important link in any electric power system, including control and operation systems for marine fishing and transport vessels and stationary marine technological complexes.

The Role of Calcitonin Gene‐Related Peptide in High‐Altitude Headache: A Prospective Field Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective High‐altitude headache (HAH) is a common neurological condition associated with rapid ascent to high altitude. The pathophysiological mechanisms underlying HAH remain incompletely understood. Calcitonin gene‐related peptide (CGRP), a neuropeptide implicated in migraine pathophysiology, may play a key role in the pathophysiology of ...
