Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Research of robust repetitive current control strategy of active power filter

open access: yesGong-kuang zidonghua, 2014
In view of problems of steady-state error and phase offset of traditional current loop PI control of active power filter, a robust repetitive current control strategy of active power filter was proposed, and concrete implementation method of robust ...

Simulation of a single-phase active power filter based ANN controller [PDF]

open access: yes, 2013
This project presents the employment of a single-phase active power filter (APF) to compensate harmonics generated by battery charger. The presence of the harmonics leads to various problems and poor power quality.

Power Flow in a Load-Current Sensorless Shunt Active Power Filter [PDF]

open access: yes, 2007
In this paper, power flow analysis of a three-phase four-wire system with a shunt active power filter in steady state is presented. The analysis begins with a mathematical model of the power inverter and continues to find the relationship of the real and

Smart Hybrid Active Power Filter Power Quality Improvement

open access: yesInternational Journal of Advanced Research in Science, Communication and Technology, 2022
Filters are devices that remove undesirable or polluting particles from a required environment. Filters are used to ensure the purity of electrical power in electrical systems. Power filters are used to handle power quality concerns such as power factor, voltage stability, and harmonics.

Identification of serum protein biomarkers for pre‐cancerous lesions associated with pancreatic ductal adenocarcinoma

open access: yesMolecular Oncology, EarlyView.
This work identified serum proteins associated with pancreatic epithelial neoplasms (PanINs) and early‐stage PDAC. Proteomics screens assessed genetically engineered mice with abundant PanINs, KPC mice (Lox‐STOP‐Lox‐KrasG12D/+ Lox‐STOP‐Lox‐Trp53R172H/+ Pdx1‐Cre) before PDAC development and also early‐stage PDAC patients (n = 31), compared to benign ...

Three phase active power filter with selective harmonics elimination

open access: yesArchives of Electrical Engineering, 2016
This paper describes a three phase shunt active power filter with selective harmonics elimination. The control algorithm is based on a digital filter bank. The moving Discrete Fourier Transformation is used as an analysis filter bank.

Power Quality Improvement in Mosul City Using Shunt Active Power Filter

open access: yesNTU Journal of Engineering and Technology, 2021
One of the most important issues in Mosul is power quality. A power quality issue caused by current harmonic pollution caused by a wide range of nonlinear loads in the electrical power system. The shunt active power filter based on instantaneous active
