Control Design Based on Generalized Lur'e Lyapunov Functions for Sampled‐Data Lur'e Systems

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT This article addresses the synthesis of stabilizing control laws for aperiodic sampled‐data Lur'e systems. Based on a hybrid system representation of the closed‐loop system and a timer‐dependent generalized Lur'e–Postnikov type Lyapunov function, stabilization conditions are obtained by separating decision variables with the application of two

Validation of Neural Network Controllers for Uncertain Systems Using the Keep‐Close Approach: Robustness Analysis and Safety Verification

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT The safety verification of neural network (NN) controllers operating in uncertain environments characterized by unmodeled dynamics, nonlinearities, and time delays remains a fundamental challenge in robust control analysis. This article introduces a novel method, termed Keep‐Close, for analyzing the performance and robustness of uncertain ...

Perspectives on Climate Change in Education for Sustainability: Linking Concepts and Skills for a Practical Ecological Transition

open access: yesSustainable Development, EarlyView.
ABSTRACT ‘Hard’ natural sciences have extensively been used to provide evidence that climate change is happening and climate action is needed. If the contribution of our economic activities to disturbing our climate systems is now largely accepted, the way in which we design and operationalise ‘climate action’—how we transition to more sustainable ...

Acoustic stimulation for sleep enhancement and declarative memory: A systematic review and meta‐analysis

open access: yesSleep Research, EarlyView.
Abstract Background Acoustic stimulation is a non‐invasive neuromodulation approach with unclear efficacy for sleep and cognition across paradigms and populations. This meta‐analysis systematically evaluated its effects on sleep architecture and declarative memory. Methods We searched the PubMed, Web of Science, the Cochrane Library, Scopus, and Embase

Programmable 3D Microfluidics Reveals Motility‐Driven Antibiotic Resistance Evolution in Gradients

open access: yesSmall, EarlyView.
Using a programmable microfluidic platform, this study shows that bacterial motility is crucial for resistance development in heterogeneous antibiotic landscapes. Motile Escherichia coli randomly migrates along antibiotic gradients, and sufficient movement is required for resistance to emerge.
