Harmonic Model of Static Var Generator and Analysis of Its Resonance Influence
Zhongguo dianli, 2022 Static var generators (SVGs) are widely used in photovoltaic (PV) stations because of their fast response speed and wide regulation range, which can meet such needs of the system as dynamic reactive power compensation.

A comparison of two configurations for a dual-resonance cymbal transducer [PDF]
, 2018 The ability to design tuned ultrasonic devices that can be operated in the same mode at two different frequencies has the potential to benefit a range of applications, such as surgical cutting procedures where the penetration through soft then hard ...

Molecular Oncology, EarlyView.This study characterizes the responses of primary acute myeloid leukemia (AML) patient samples to the MCL‐1 inhibitor MIK665. The results revealed that monocytic differentiation is associated with MIK665 sensitivity. Conversely, elevated ABCB1 expression is a potential biomarker of resistance to the treatment, which can be overcome by the combination ...

Molecular Oncology, EarlyView.Development of therapies targeting cancer‐associated fibroblasts (CAFs) necessitates preclinical model systems that faithfully represent CAF–tumor biology. We established an in vitro coculture system of patient‐derived pancreatic CAFs and tumor cell lines and demonstrated its recapitulation of primary CAF–tumor biology with single‐cell transcriptomics ...

Second harmonic impedance drift‐based islanding detection method
IET Generation, Transmission & Distribution, 2019 Islanding detection is an important operational aspect of microgrids. Early detection of islanding is essential to avoid unsynchronised reclosing. The possibility for minimal or near zero power mismatch between generation and load of a microgrid is high ...

Análisis de armónicos variando en el tiempo en sistemas eléctricos de potencia con parques eólicos, a través de la teoría de la posibilidad [PDF]
, 2015 This paper focuses on the analysis of the connection of wind farms to the electric power system and their impact on the harmonic load-flow. A possibilistic harmonic load-flow methodology, previously developed by the authors, allows for modeling ...

Molecular Oncology, EarlyView.The LINC01116 long noncoding RNA is induced by hypoxia and associated with poor prognosis and high recurrence rates in two cohorts of lung adenocarcinoma patients. Here, we demonstrate that besides its expression in cancer cells, LINC01116 is markedly expressed in lymphatic endothelial cells of the tumor stroma in which it participates in hypoxia ...
