Optimal Output Regulation for Square, Over-Actuated and Under-Actuated Linear Systems
, 2019 This paper considers two different problems in trajectory tracking control for linear systems. First, if the control is not unique which is most input energy efficient. Second, if exact tracking is infeasible which control performs most accurately. These

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).

Distributed static output feedback control for interconnected systems in finite‐frequency domain
IET Control Theory & Applications, 2021 This paper aims at designing a distributed static output feedback (DSOF) controller for the interconnected system in finite‐frequency domain. Motivated by the fact that the signal transmitting process is usually affected by surrounding environments, the ...

Journal of Mathematical Analysis and Applications, 1987 These two papers develop a state space theory for an abstract control system which includes a very large class of linear time-invariant hereditary systems: delay-differential equations, integro-differential equations, Volterra-Stieltjes integral equations, functional differential equations of retarded and neutral type, with finite or infinite memory. ``

A Linear Control Theory Analysis of Transverse Coherent Bunch Instabilities Feedback Systems (The Control Theory Approach to Hill's Equation) [PDF]
, 1993 There is an on-going effort to build a feedback system for transverse coherent bunch instabilities for ALS [1,2,3]. The beam dynamics issues were already addressed in the conceptual design report [ 4] and more detailed studies have been earned out [5 ...

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Human Control Model Estimation in Physical Human–Machine Interaction: A Survey
Sensors, 2022 The study of human–machine interaction as a unique control system was one of the first research interests in the engineering field, with almost a century having passed since the first works appeared in this area.

Distributed Consensus of Linear Multi-Agent Systems with Switching Directed Topologies
, 2014 This paper addresses the distributed consensus problem for a linear multi-agent system with switching directed communication topologies. By appropriately introducing a linear transformation, the consensus problem is equivalently converted to a ...

Structural biology of ferritin nanocages
FEBS Letters, EarlyView.Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

A theory of the infinite horizon LQ-problem for composite systems of PDEs with boundary control
, 2012 We study the infinite horizon Linear-Quadratic problem and the associated algebraic Riccati equations for systems with unbounded control actions. The operator-theoretic context is motivated by composite systems of Partial Differential Equations (PDE ...
