Genetic and combinatorial algorithms for optimal sizing and placement of active power filters
International Journal of Applied Mathematics and Computer Science, 2015 The paper deals with cost effective compensator placement and sizing. It becomes one of the most important problems in contemporary electrical networks, in which voltage and current waveform distortions increase year-by-year reaching or even exceeding ...

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation
FEBS Letters, EarlyView.Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

Repetitive-Based Control for Selective Active Filters Using Discrete Cosine Transform
Eletrônica de Potência, 2004 This paper proposes selective harmonic current compensation using a closed-loop repetitive controller. The controller is based on measuring the line currents. It performs the compensation of specific harmonics selected by a DCT (Discrete Cosine Transform)

FEBS Letters, EarlyView.Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.
