This study presents design of D-Σ digital controlled hybrid-frequency inverters with LCL filter for grid-connected applications. Hybrid-frequency inverters consist of inverters with different frequencies and power ratings connected in parallel. The lower frequency inverter has higher power rating, while the higher frequency inverter has lower one. The inverters are controlled to cancel out low-frequency...
West Nile virus (WNV), like all members of the Japanese encephalitis (JE) serogroup except JE virus, contains three N-linked glycosylation (N-X-S/T) sites in the NS1 protein at asparagine residues NS1 130 , NS1 175 and NS1 207 . Previously we showed that the ablation of these glycosylation sites in WNV, by substitution of asparagine for alanine, attenuated mouse neuroinvasiveness;...
Site-directed mutagenesis of residues in the BC loop (residues 329–333) of the envelope (E) protein domain III in a West Nile virus (WNV) infectious clone and in plasmids encoding recombinant WNV and dengue type 2 virus domain III proteins demonstrated a critical role for residues in this loop in the function and antigenicity of the E protein. This included a strict requirement for the tyrosine at...
