Insertion of the FeB cofactor in cNORs lacking metal inserting chaperones
FEBS Letters, EarlyView.Nitric oxide reductase is an enzyme found in the bacterial denitrification pathway. The NOR active site contains a non‐heme iron, often, but not always inserted with the assistance of chaperones. Here, we study the insertion of FeB in the subfamily of cNORs lacking chaperones and found a putative channel, conserved in the family, perhaps enabling the ...

Robust localization in wireless networks from corrupted signals
EURASIP Journal on Advances in Signal Processing, 2021 We address the problem of timing-based localization in wireless networks, when an unknown fraction of data is corrupted by non-ideal propagation conditions.

Robustness under control sampling of reachability in fixed time for nonlinear control systems [PDF]
arXiv, 2020 Under a regularity assumption we prove that reachability in fixed time for nonlinear control systems is robust under control sampling.

Analytical Volume Analysis for the Finite-time Controllable Region of the Linear Discrete-time Systems [PDF]
arXiv, 2022 In this paper, the works on the analytical volume analysis for the controllable regions of the linear discrete-time (LDT) systems in papers \cite{zhaomw202001} and \cite {zhaomw202004} are discussed further and a new theorem on the analytical computing for the finite-time controllability zonotope (controllable region) of LDT systems are proven.

Quantum control theory and applications: A survey [PDF]
IET Control Theory & Applications, vol. 4, no. 12, pp.2651-2671,
2010, 2009 This paper presents a survey on quantum control theory and applications from a control systems perspective. Some of the basic concepts and main developments (including open-loop control and closed-loop control) in quantum control theory are reviewed. In the area of open-loop quantum control, the paper surveys the notion of controllability for quantum ...

Remarks on the Relay Controllability of Control Systems
Journal of Mathematical Analysis and Applications, 1994 AbstractFor a control process governed by a differential equation a special controllability property is studied. We consider relay controls, that is, piecewise constant scalar controls whose absolute value is constant, and we give sufficient conditions for the controllability by means of relay controls with a minimum number of switches or with a ...

FEBS Letters, EarlyView.LHCPs are transported to the thylakoid membrane via the (cp)SRP pathway. This process involves a transit complex of (cp)SRP43, (cp)SRP54 and LHCP, which interacts with (cp)FtsY and Alb3 at the membrane. GTP hydrolysis by (cp)SRP54 and (cp)FtsY triggers complex dissociation.

Taurine promotes glucagon‐like peptide‐1 secretion in enteroendocrine L cells
FEBS Letters, EarlyView.Taurine, a sulfur‐containing amino acid, is likely taken up by enteroendocrine L cells via the taurine transporter. This process increases the levels of cytosolic ATP. The increase in intracellular Ca2+ concentrations and glucagon‐like peptide‐1 secretion through membrane depolarization is caused by the closure of ATP‐sensitive potassium channels ...

Quantum controllers for quantum systems [PDF]
arXiv, 1997 This paper discusses fully coherent quantum feedback control, in which the sensors, controller, and actuators are quantum systems and interact coherently with the system to be controlled: as a result, the entire feedback loop is coherent. Unlike conventional semiclassical feedback control of quantum systems, feedback control by quantum controllers is ...
