Passive Islanding Detection Using Inverter Nonlinear Effects

IEEE Transactions on Power Electronics, 2017
This paper analyzes the use of the voltage distortions in pulse width modulation voltage-source inverters caused by the inverter switching for islanding detection purposes. The nonideal characteristics of the inverters, mainly due to the dead time needed to have safe commutations, produce fundamental frequency-dependent harmonics (−5th, 7th, …) in the ...

COMP–PMEPA1 axis promotes epithelial‐to‐mesenchymal transition in breast cancer cells

Molecular Oncology, EarlyView.
This study reveals that cartilage oligomeric matrix protein (COMP) promotes epithelial‐to‐mesenchymal transition (EMT) in breast cancer. We identify PMEPA1 (protein TMEPAI) as a novel COMP‐binding partner that mediates EMT via binding to the TSP domains of COMP, establishing the COMP–PMEPA1 axis as a key EMT driver in breast cancer.
