Necessary and sufficient conditions for stabilisability of discrete‐time time‐varying switched systems

open access: yesIET Control Theory & Applications, 2021
This paper is concerned with necessary and sufficient conditions for stabilisability of time‐varying discrete‐time switched systems. Starting with an asymptotically stable function, an exponentially stable function and a uniformly exponentially stable ...

Graph Laplacians and Stabilization of Vehicle Formations [PDF]

open access: yes, 2001
Control of vehicle formations has emerged as a topic of significant interest to the controls community. In this paper, we merge tools from graph theory and control theory to derive stability criteria for formation stabilization.

Feedback Control as a Framework for Understanding Tradeoffs in Biology [PDF]

open access: yes, 2014
Control theory arose from a need to control synthetic systems. From regulating steam engines to tuning radios to devices capable of autonomous movement, it provided a formal mathematical basis for understanding the role of feedback in the stability (or ...

Speciation Through the Lens of Population Dynamics: A Theoretical Primer on How Small and Large Populations Diverge

open access: yesPopulation Ecology, EarlyView.
Population size and dynamics fundamentally shape speciation by influencing genetic drift, founder events, and adaptive potential. Small populations may speciate rapidly due to stronger drift, whereas large populations harbor more genetic diversity, which can alter divergence trajectories. We highlight theoretical models that incorporate population size

A binary quadratic function negative‐determination lemma and its application to stability analysis of systems with two additive time‐varying delay components

open access: yesIET Control Theory & Applications, 2021
This paper concentrates on the stability problem of systems with two additive time‐varying delay components. For the construction of Lyapunov–Krasovskii functional (LKF), in the case that the introduced augmented vector contains the double integral term ...

FoxO1 signaling in B cell malignancies and its therapeutic targeting

open access: yesFEBS Letters, EarlyView.
FoxO1 has context‐specific tumor suppressor or oncogenic character in myeloid and B cell malignancies. This includes tumor‐promoting properties such as stemness maintenance and DNA damage tolerance in acute leukemias, or regulation of cell proliferation and survival, or migration in mature B cell malignancies.

Exponential sampled‐data fuzzy stabilization of nonlinear systems and its application to basic buck converters

open access: yesIET Control Theory & Applications, 2021
This study focuses on the exponential stability and stabilization of nonlinear systems via fuzzy sampled‐data control technique. The stability and stabilization conditions are obtained through constructing suitable Lyapunov functional which contains the ...

Some Unsolved Problems in Stability and Optimal Control Theory of Stochastic Systems

open access: yesMathematics, 2022
In spite of the fact that the theory of stability and optimal control for different types of stochastic systems is well developed and very popular in research, there are some simply and clearly formulated problems, solutions of which have not been found ...

Evolutionary interplay between viruses and R‐loops

open access: yesFEBS Letters, EarlyView.
Viruses interact with specialized nucleic acid structures called R‐loops to influence host transcription, epigenetic states, latency, and immune evasion. This Perspective examines the roles of R‐loops in viral replication, integration, and silencing, and how viruses co‐opt or avoid these structures.

An improved control technique for designing of composite non‐linear feedback control in constrained time‐delay systems

open access: yesIET Control Theory & Applications, 2021
In this research, a novel delay‐dependent composite non‐linear feedback (CNF) control would be pointed for non‐linear time‐delay systems under actuator saturation.
