Functional insights from a surface antigen mRNA-bound proteome
eLife, 2021 Trypanosoma brucei is the causative agent of human sleeping sickness. The parasites’ variant surface glycoprotein (VSG) enables them to evade adaptive immunity via antigenic variation. VSG comprises 10% of total cell protein and the high stability of VSG

Current-Limiting VSG for Renewable Energy Applications
2021 IEEE 30th International Symposium on Industrial Electronics (ISIE), 2021 In this paper, an improved nonlinear controller structure, which inherits both virtual inertia (VI) and current-limiting properties in grid-connected voltage-source converters (VSCs), is proposed. The proposed method inherits the V dc ~ ω droop control for inertia emulation and frequency control, and Q ~ V droop control for AC voltage support.

Mapping of VSG similarities in Trypanosoma brucei [PDF]
Molecular and Biochemical Parasitology, 2012 The protozoan parasite Trypanosoma brucei switches its variant surface glycoprotein (VSG) to subvert its mammalian hosts' immune responses. The T. brucei genome contains as many as 1600 VSG genes (VSGs), but most are silent noncoding pseudogenes. Only one functional VSG, located in a telomere-linked expression site, is transcribed at a time.
