Conserved structural motifs in PAS, LOV, and CRY proteins regulate circadian rhythms and are therapeutic targets

FEBS Letters, EarlyView.
Cryptochrome and PAS/LOV proteins play intricate roles in circadian clocks where they act as both sensors and mediators of protein–protein interactions. Their ubiquitous presence in signaling networks has positioned them as targets for small‐molecule therapeutics. This review provides a structural introduction to these protein families.

Unified model of voltage/current mode control to predict saddle-node bifurcation

, 2012
A unified model of voltage mode control (VMC) and current mode control (CMC) is proposed to predict the saddle-node bifurcation (SNB). Exact SNB boundary conditions are derived, and can be further simplified in various forms for design purpose.

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

FEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Quantitative stability analysis of STATCOM in voltage control mode and Enhanced control method based on voltage feedforward

International Journal of Electrical Power & Energy Systems
STATCOM is a crucial device for reactive power compensation and voltage regulation. However, under weak grid conditions, oscillations may arise during voltage control (VC) mode operation due to the AC Voltage Controller (AVC), potentially jeopardizing ...

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

FEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Fast control technique for high frequency DC/DC integrated converter based on non-invasive output capacitance current estimation [PDF]

, 2010
High switching frequency allows the integration of low power DC/DC converters. Although a high switching frequency would make feasible a voltage mode control with 1MHz bandwidth, parasitic effects and robustness don’t allow such a high bandwidth ...

Sliding Mode Control Strategy of Dynamic Voltage Restorer

2005 International Conference on Industrial Electronics and Control Applications, 2006
The dynamic voltage restorer (DVR) is great significance for improving power quality as a cost effective solution for the protection of sensitive loads from voltage sags. This paper summarizes sliding mode control (SMC) method used in current control strategies for DVR including forward-feed control and PI feedback control.
