Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Feedforward of Measurable Disturbances to Improve Multi-Input Feedback Control
Mathematics, 2021 The availability of multiple inputs (plants) can improve output performance by conveniently allocating the control bandwidth among them. Beyond that, the intervention of only the useful plants at each frequency implies the minimum control action at each ...

Algorithms for output feedback, multiple-model, and decentralized control problems [PDF]
, 1984 The optimal stochastic output feedback, multiple-model, and decentralized control problems with dynamic compensation are formulated and discussed. Algorithms for each problem are presented, and their relationship to a basic output feedback algorithm is ...

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 ...

Delta-Modulator-Based Quantised Output Feedback Controller for Linear Networked Control Systems
IEEE Access, 2020 This article proposes a Δ -Modulator ( Δ -M) based quantised output feedback controller for linear networked systems. The proposed Δ -M is essentially a 2-level quantiser, in contrast to some of the existing quantisers such as 2p ...

Dynamic Modeling and Passivity-Based Control of an RV-3SB Robot
Actuators, 2023 This paper shows the dynamic modeling and design of a passivity-based controller for the RV-3SB robot. Firstly, the dynamic modeling of a Mitsubishi RV-3SB robot is conducted using Euler–Lagrange formulation in order to obtain a decoupled dynamic model ...

Output Feedback Event-Triggered Control [PDF]
, 2016 Event-triggered control has been proposed as an alternative implementation to conventional time-triggered approach in order to reduce the amount of transmissions. The idea is to adapt transmissions to the state of the plant such that the loop is closed only when it is needed according to the stability or/and the performance requirements.

Output feedback control of linear multipass processes [PDF]
, 2001 An error actuated output feedback controller for a sub-class of linear multipass processes designated as 'differential unit memory' is defined. Further, the design of this controller for closed-loop stability is considered.

Output feedback stable stochastic predictive control with hard control constraints
, 2017 We present a stochastic predictive controller for discrete time linear time invariant systems under incomplete state information. Our approach is based on a suitable choice of control policies, stability constraints, and employment of a Kalman filter to ...
