Six‐phase SVPWM with common‐mode voltage suppression [PDF]
IET Power Electronics, 2018 There are two common‐mode voltages (CMVs) in a six‐phase machine with two Y‐connected windings shifted by 30°, which bring adverse effects on the six‐phase system. In this study, a method of six‐phase space vector pulse width modulation (SVPWM) is proposed, which can suppress the magnitude and frequency of the two CMVs.

Novel Common-Mode Current Suppression Method in Transformerless PV Grid-Connected System
Applied Sciences, 2018 The existence of high-frequency components in common-mode (CM) current would reduce the stability of a non-isolated PV grid-connected system. It has great impacts on the output power quality when the generated power from PV is low.

FEBS Letters, EarlyView.Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

A Reconfigurable Filter Using Defected Ground Structure for Wideband Common-Mode Suppression
IEEE Access, 2019 A wideband common-mode (CM) suppression reconfigurable filter is proposed for high-speed all-pass differential circuits. The filter adopts three varactor-loaded compact defected ground structures (DGSs) to achieve continuous reconfigurability in its ...

Reciprocal control of viral infection and phosphoinositide dynamics
FEBS Letters, EarlyView.Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.
