Observer-Based Bipartite Consensus of Linear Multi-Agent Systems With Measurement Noises

IEEE Access, 2019
This paper considers the bipartite consensus of linear multi-agent systems with measurement noise, in which both the cooperation and competition relations exist among agents. To attenuate the influence of measurement noises, an important function α

Speed Control of Permanent Magnet DC Motor with Friction and Measurement Noise Using Novel Nonlinear Extended State Observer-Based Anti-Disturbance Control

Energies, 2019
In this paper, a novel finite-time nonlinear extended state observer (NLESO) is proposed and employed in active disturbance rejection control (ADRC) to stabilize a nonlinear system against system’s uncertainties and discontinuous disturbances using

Guidelines for Pediatric Radiotherapy Simulation: A Report From the Children's Oncology Group Radiation Oncology Discipline

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric radiation therapy presents unique challenges compared to adult treatments, including those of immobilization, potential need for sedation, and the critical importance of accurate, reproducible positioning. Additionally, heightened attention to imaging doses is necessary to minimize long‐term toxicity in survivors.

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 ...

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

FEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

A flatness-based adaptive fuzzy control method for an endogenous economic growth model [PDF]

Artificial Intelligence and Autonomous Systems
The article proposes a flatness-based adaptive control approach for the Uzawa-Lucas financial growth model. This model describes interaction between physical and human capital within an economy and so far equilibria and bifurcations have been computed ...

A correction note on "Output feedback stabilization"

IEEE Transactions on Automatic Control, 1994
In a previous paper by the authors (see ibid., vol. 35, no.8, p.951-4, 1990), necessary and sufficient Lyapunov-like conditions for output feedback stabilisation of nonlinear systems were derived. In this paper the authors point out an omission. >
