FPGA implementation of impedance-compensated phase-locked loop for HVDC converters
The Journal of Engineering, 2018 The phase-locked loop (PLL) plays a key role in HVDC systems. Recently, a new type of PLL called the impedance-compensated phase-locked loop (IC-PLL) was introduced to compensate for the voltage drop across the AC network's Thevenin impedance, making the

Optimization of CEST MRI Reporter Protein Design Using Cation‐Pi Networks
Chemistry – A European Journal, EarlyView.A novel engineering approach can produce reporter proteins for cell and viral therapy tracking with unique magnetic resonance imaging (MRI) signatures, detectable with chemical exchange saturation transfer (CEST). We discover how cation‐π interactions between amino acid groups can help us fine‐tune magnetic resonance properties for noninvasive ...
