An optimal gains matrix for time-delay feedback control [PDF]
, 2009 In this paper we propose an optimal time-delayed feedback control (TDFC) for tracking unstable periodic orbits (UPOs). It is shown that TDFC will drive a trajectory onto a periodic orbit while minimising an integral of a cost function of the error in ...

Feedback Stability for Dissipative Switched Systems
IFAC-PapersOnLine, 2017 A method is proposed to infer Lyapunov and asymptotic stability properties forswitching systems, under arbitrary continuous-state feedback. Continuous-time systems which are dissipative in the multiple-storage function sense are considered. A partition of the state space, induced by the cross-supply rates and the feedback function, is used to derive ...

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 ...

FEBS Letters, EarlyView.Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Output Feedback Adaptive Stabilization of Uncertain Nonholonomic Systems
Abstract 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 ...

Stability improvement of nonlinear systems by feedback
IEEE 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,

The human gut microbiome across the life course
FEBS Letters, EarlyView.Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.
