A Comparative Study of Recent Discontinuous Modulation Techniques for Three-Phase Impedance Source Inverter [PDF]
, 2021 Since the Z-Source Inverter (ZSI) was first proposed in 2003, impedance source inverters (ISI) have experienced a rapid progress. This evolution is not limited to developing network topologies, but also involves their modulation and control techniques to

A discontinuous autoinhibitory module masks the A1 domain of von Willebrand factor [PDF]
Journal of Thrombosis and Haemostasis, 2017 Essentials The mechanism for the auto-inhibition of von Willebrand factor (VWF) remains unclear. Hydrogen exchange of two VWF A1 fragments with disparate activities was measured and compared. Discontinuous residues flanking A1 form a structural module that blocks A1 binding to the platelet.
