Design and implementation of a three-level active power filter for harmonic and reactive power compensation

, 2018
This paper presents a unified design and implementation of active power filters (APF) for medium-voltage high-power applications. A fast and accurate harmonic extraction technique based on the time transformation algorithm (TTA) is developed.

Gut microbiota alterations in patients with non‐small‐cell lung cancer undergoing chemoradiotherapy

Molecular Oncology, EarlyView.
We investigated the impact of concurrent chemoradiotherapy (CRT) on the gut microbiota in patients with locally advanced non‐small‐cell lung cancer. Overall gut microbiota composition remained largely stable throughout CRT while antibiotic exposure may influence microbial diversity.

New hybrid parallel active filter configuration minimising active filter size

, 2000
The authors propose a new topology for a hybrid parallel active filter that can further reduce the active filter (inverter) power rating. The basic idea is to install the active filter in parallel with the passive filter inductor.

Extracellular vesicle lipidomics liquid biopsy reveals systemic and tumor microenvironment metabolic reprogramming in ovarian cancer

Molecular Oncology, EarlyView.
Extracellular vesicle (EV) lipidomic profiling of plasma and ascites from patients with high‐grade serous ovarian cancer and of ovarian cancer cell lines reveals enrichment of triglycerides (TGs), diacylglycerols (DGs), phosphatidylcholine (PCs), sphingomyelins (SMs), reflecting tumor metabolic reprogramming.
