Learning Koopman Reduced-Order Model for Feedback Control in Dexterous Manipulation
IEEE AccessWe propose a data-driven feedback control method for dexterous manipulation that uses a Koopman-based reduced-order model (ROM) and a simple static state-feedback law in a lifted state space.

Advanced Functional Materials, EarlyView.Blue phosphorescent OLEDs remain limited by poor operational stability. Here, a unified analytical framework integrating transient photoluminescence and magneto‐electroluminescence is developed to correlate intrinsic material photophysics with electrically driven degradation.

Pickering‐Engineered Microparticles for Magnetically Guided Motion and Light‐Triggered Catalysis
Advanced Functional Materials, EarlyView.Magnetically responsive wax microparticles stabilized by hematite cubes through the Pickering emulsification strategy are developed, showing controlled size, motion, and light‐activated catalytic activity. Annealing under a magnetic field enhances their mobility and steering.

Application of Ibuprofen Sodium Dihydrate for Thermochemical Energy Storage
Advanced Functional Materials, EarlyView.Ibuprofen sodium dihydrate is introduced as a durable organic salt hydrate for low‐temperature thermochemical energy storage, operating within 60°C–110°C with high energy density. At the material level, it delivers ∼99.9% cycling efficiency over 150 cycles without deliquescence, enabled by a dual energy‐storage mechanism coupling dehydration and phase ...

Wavelet-Based Observables for Koopman Analysis: An Extended Dynamic Mode Decomposition Framework
We present an in-depth analysis of the Koopman semigroup via wavelet transform. Towards this goal, we start by introducing the wavelet-based observables and show that they are eigenfunctions of the Koopman semigroup when this semigroup is considered over the Banach space of continuous functions on a compact forward-invariant set endowed with the ...
