PI(3,4,5)P3 allosteric regulation of repressor activator protein 1 controls antigenic variation in trypanosomes

eLife, 2023
African trypanosomes evade host immune clearance by antigenic variation, causing persistent infections in humans and animals. These parasites express a homogeneous surface coat of variant surface glycoproteins (VSGs).

Improved Virtual Synchronous Generator-Based Control Scheme for Enhanced Transient Response in Microgrids

Engineering Proceedings, 2023
Synchronous generator-based power stations, with their inherent inertia, can maintain frequency stability during sudden load switching, while distributed generating station-driven microgrids suffer from a lack of natural inertia. Cascaded power, voltage,

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.

State observer to improve the VSG control stability [PDF]

IECON 2020 The 46th Annual Conference of the IEEE Industrial Electronics Society, 2020
This paper proposes an observer-based current controller for a virtual synchronous generators (VSG) to improve its operational performances. First, the model and the controllers are analytically described. Two controller are compared to the proposed one (PI integrating a state observer): a traditional PI and a PI integrating virtual impedances for ...

Turnover of Variant Surface Glycoprotein in Trypanosoma brucei Is Not Altered in Response to Specific Silencing

mSphere, 2022
African trypanosomes evade the immune system of the mammalian host by the antigenic variation of the predominant glycosylphosphatidylinositol (GPI)-anchored surface protein, variant surface glycoprotein (VSG).
