Output Feedback Adaptive Stabilization of Uncertain Nonholonomic Systems

open access: yesAbstract and Applied Analysis, 2014
This paper investigates the problem of output feedback adaptive stabilization control design for a class of nonholonomic chained systems with uncertainties, involving virtual control coefficients, unknown nonlinear parameters, and unknown time delays ...

Autophagy and mitophagy in pancreatic β‐cell homeostasis and their involvement in diabetes pathophysiology

open access: yesFEBS Letters, EarlyView.
This review focuses on the role of autophagy and mitophagy in maintaining pancreatic β‐cell function and homeostasis. We discuss how genetic defects affecting these pathways contribute to the development of type 1, type 2, monogenic, and gestational diabetes. We further explore their potential as therapeutic targets. Created in BioRender.

Stability improvement of nonlinear systems by feedback

open access: yesIEEE Transactions on Automatic Control, 1984
Two main results concerning systems stabilization are given. The first one is that systems with controllable linearization at a critical point are precisely those that can be driven to that point arbitrarily fast by smooth feedback. In addition the authors generalize a knewly sufficient condition involving the existence of a global feedback stabilizer,

From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

open access: yesFEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

Simultaneous output-feedback stabilization for continuous systems in Banach spaces [PDF]

open access: yes, 1998
summary:A design technique for the stabilization of $M$ linear systems by one constant output-feedback controller is developed. The design equations are functions of the state and the control weighting matrices.

Stochastic Stabilization of Itô Stochastic Systems with Markov Jumping and Linear Fractional Uncertainty

open access: yesJournal of Control Science and Engineering, 2013
For a class of Itô stochastic linear systems with the Markov jumping and linear fractional uncertainty, the stochastic stabilization problem is investigated via state feedback and dynamic output feedback, respectively.

The ubiquitin system in normal and infected germinal center B cells

open access: yesFEBS Letters, EarlyView.
The ubiquitin system plays a central role in germinal center (GC) B cells, influencing differentiation to long‐lived memory B cells. Oncogenic gammaherpesviruses gain access to memory B cells by establishing latency in GC B cells. Mapping ubiquitin mechanisms in normal and infected GC B cells will define specific molecular circuits in B cells germane ...

Feedback Stabilization of Quasi-One-Sided Lipschitz Nonlinear Discrete-Time Systems with Reduced-Order Observer

open access: yesMathematics
The feedback stabilization problem for nonlinear discrete-time systems with a reduced-order observer is investigated, in which the nonlinear terms of the systems satisfy the quasi-one-sided Lipschitz condition.

Analysis and Design of Robust Positivity and Stability for Continuous-Time Linear Uncertain Systems

open access: yesJournal of Applied Mathematics, 2015
This paper deals with the analysis and design of positivity and stability of linear continuous conic systems. First, two robustness analysis theorems are proposed for the systems with state-feedback.
