Reactive power adjustable ability of HVDC under steady state condition

电力工程技术
The high voltage direct current (HVDC) converter has a certain dynamic reactive power regulation ability. Making full use of the reactive power regulation ability of the converter station can significantly improve the stability of the HVDC. In this paper,

Insights into a long life without cancer: The case of the bowhead whale

Molecular Oncology, EarlyView.
Long‐lived, large‐bodied organisms have evolved powerful anticancer mechanisms that preserve cellular and tissue integrity across extended lifespans. A recent study by Firsanov et al. shows that greater genome stability is a key factor underlying the remarkable longevity and cancer resistance of one such species, the bowhead whale.

DNA methylation and expression of MAPRE3 affect overall survival of early‐stage non‐small cell lung cancer patients

Molecular Oncology, EarlyView.
Both cg12821679MAPRE3 methylation and MAPRE3 expression are significantly associated with overall survival (OS) of non‐small cell lung cancer. Meanwhile, MAPRE3 expression significantly modified the effect of smoking cessation on OS. Smoking cessation benefits OS merely for patients with high MAPRE3 expression.

Research on Reactive Power Coordination Control of Urban Rail Transit Power Monitoring System

Chengshi guidao jiaotong yanjiu
[Objective] The power supply system of urban rail transit mainly relies on the SVG (static var generator) or reactors in the 110 kV main substation for centralized reactive power compensation. The current control mode does not fully consider the reactive

Tumor‐stromal crosstalk and macrophage enrichment are associated with chemotherapy response in bladder cancer

FEBS Open Bio, EarlyView.
Chemoresistance in bladder cancer: Macrophage recruitment associated with CXCL1, CXCL5 and CXCL8 expression is characteristic of Gemcitabine/Cisplatin (Gem/Cis) Non‐Responder tumors (right side) while Responder tumors did not show substantial tumor‐stromal crosstalk (left side). All biological icons are attributed to Bioicons: carcinoma, cancerous‐cell‐

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

FEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Analysis of Reactive Power Demand Based on Voltage-Reactive Power Correlation

Journal of Physics: Conference Series, 2019
AbstractThe inaccuracy of reactive power demand analysis in practical power system often leads to the problem of low voltage stability margin. In this paper, the analysis method of voltage-reactive power correlation is proposed, which is used to solve the inaccuracy of reactive power demand analysis. The proposed method can quickly analyze the reactive
