Global Stability Analysis Using the Eigenfunctions of the Koopman Operator [PDF]
IEEE Transactions on Automatic Control, 2014 We propose a novel operator-theoretic framework to study global stability of nonlinear systems. Based on the spectral properties of the so-called Koopman operator, our approach can be regarded as a natural extension of classic linear stability analysis ...

FEBS Letters, EarlyView.Interaction extracellular vesicles (iEVs) are hybrid vesicles formed through host‐pathogen communication. They facilitate immune evasion, transfer pathogens' molecules, increase host cell uptake, and enhance virulence. This Perspective article illustrates the multifunctional roles of iEVs and highlights their emerging relevance in infection dynamics ...

Smoothness dependent stability in corrosion detection
, 2014 We consider the stability issue for the determination of a linear corrosion in a conductor by a single electrostatic measurement. We established a global log-log type stability when the corroded boundary is simply Lipschitz. We also improve such a result

Adaptive Neural Globally Asymptotic Tracking Control for a Class of Uncertain Nonlinear Systems
IEEE Access, 2019 This paper investigates the adaptive neural tracking control problem for strict-feedback nonlinear systems. Superior to the existing results that only semi-globally uniformly ultimately bounded stability can be achieved, each virtual and actual ...

Global exponential stabilization of freeway models [PDF]
International Journal of Robust and Nonlinear Control, 2015 SummaryThis work is devoted to the construction of feedback laws, which guarantee the robust global exponential stability of the uncongested equilibrium point for general discrete‐time freeway models. The feedback construction is based on a control Lyapunov function approach and exploits certain important properties of freeway models.

A stepwise emergence of evolution in the RNA world
FEBS Letters, EarlyView.How did biological evolution emerge from chemical reactions? This perspective proposes a gradual scenario of self‐organization among RNA molecules, where catalytic feedback on random mixtures plays the central role. Short oligomers cross‐ligate, and self‐assembly enables heritable variations. An event of template‐externalization marks the transition to

Global stability and repulsion in autonomous Kolmogorov systems [PDF]
, 2015 Criteria are established for the global attraction, or global repulsion on a compact invariant set, of interior and boundary fixed points of Kolmogorov systems. In particular, the notions of diagonal stability and Split Lyapunov stability that have found
