Predictive control of networked systems with communication delays

open access: yes, 2012
This paper studies the problem of predictive output feedback control for networked control systems with random communication delays. A networked predictive control scheme is employed to compensate for random communication delays, which mainly consists of

Experimental and numerical study on surface roughness of magnetorheological elastomer for controllable friction

open access: yesFriction, 2019
Magnetorheological elastomer (MRE) is a type of smart material of which mechanical and electrical properties can be reversibly controlled by the magnetic field.

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

open access: yesFEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Robust H∞ control of networked control systems with access constraints and packet dropouts

open access: yes, 2010
We consider a class of networked control systems (NCSs) where the plant has time-varying norm-bounded parameter uncertainties, the network only provides a limited number of simultaneous accesses for the sensors and actuators, and the packet dropouts ...

Random-Set-Based Estimation in Networked Environments and a Relationship to Kalman Filtering with Intermittent Observations

open access: yes, 2016
Firstly, an exposition of random-set-based estimation in general networked control systems is examined. This provides a background for the work introduced in this paper.

Controlling Networks of Imitative Agents

open access: yesIEEE Transactions on Network Science and Engineering, 2017
We consider how asynchronous networks of agents who imitate their highest-earning neighbors can be efficiently driven towards a desired strategy by offering payoff incentives, either uniformly or targeted to individuals. In particular, if for each available strategy, agents playing that strategy receive maximum payoff when their neighbors play that ...

Stability of networked control systems based on switched technique

open access: yes, 2003
In this paper we discuss the stability of networked control systems where the networked-induced delay tau(k) is not constant. We introduce some novel concepts and design feedback matrices K-i and a switched strategy among them.

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

open access: yesFEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Robust H∞ control for networked control systems with uncertainties and multiple-packet transmission

open access: yes, 2010
A class of networked control systems is investigated where the plant has time-varying norm-bounded parameter uncertainties, both the sensor-to-controller and controller to-actuator channels implement multiple-packet transmission and experience random ...

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...
