Suppression of Common-Mode Resonance in Multiband Base Station Antennas [PDF]
Sensors, 2023 5G demands a significant increment in the number of connected devices. As a result, gNodeBs are constantly pushed to serve more spectrum and smaller sectors. These increased capacity demands are met by using multiband antennas in base stations.

A common mode of recognition for methylated CpG [PDF]
Trends in Biochemical Sciences, 2013 Much is known about vertebrate DNA methylation, however it is not known how methylated CpG within particular sequences is recognized. Two recent structures of C2H2 zinc finger (ZnF) proteins in complex with methylated DNA reveal a common recognition mode for 5-methylcytosine (5mC) that involves a 5mC-Arg-G triad.

A New High Gain AC-Decoupled Transformerless Inverter for Photovoltaic Applications
Journal of Applied Science and Engineering, 2022 Transformerless inverters are prominently used in the single-phase grid-connected system due to their reduced size, weight, and high efficiency. Common-mode leakage current is the main issue of transformerless inverters, which has to be mitigated.
