Evaluation of the Regions of Attraction of Higher-Dimensional Hyperbolic Systems Using Extended Dynamic Mode Decomposition

Automation, 2023
This paper provides the theoretical foundation for the approximation of the regions of attraction in hyperbolic and polynomial systems based on the eigenfunctions deduced from the data-driven approximation of the Koopman operator.

The point spectrum of Frobenius-Perron and Koopman operators [PDF]

Proceedings of the American Mathematical Society, 1998
Summary: We present some results on the point spectrum of the Frobenius-Perron operator \(P:L^1\to L^1\) and the Koopman operator \(U: L^\infty\to L^\infty\) associated with a nonsingular transformation \(S: X\to X\) on a \(\sigma\)-finite measure space \((X,\Sigma,\mu)\).

A Novel Co3Se4‐CNFs Hybrid System as a Versatile Enhancer for Pd NPs Toward Ethylene Glycol Electrooxidation

Advanced Materials Interfaces, EarlyView.
Pd nanoparticles anchored on a Co3Se4‐CNF hybrid support exhibit enhanced electrocatalytic performance for ethylene glycol oxidation in alkaline media. The synergistic interaction between Co3Se4 and CNFs improves electronic conductivity, promotes uniform Pd dispersion, and reduces charge transfer resistance, resulting in superior activity, durability ...

Serine Grafted Silica Coated Nanoscale Zero‐Valent Iron with Enhanced Fenton‐Like Degradation of Mixed Organic Solvents of Tributyl Phosphate and n‐dodecane

Advanced Science, EarlyView.
Serine grafted silica coated nanoscale zero‐valent iron is synthesized. Through the SiO2 coating and serine grafting, the aggregation and oxidation of nZVI are reduced, and the slow release of Fe2+ ensured the catalytic cycle. The adsorption capacity for TBP and n‐dodecane is higher, because of the synergistic effect of surface functional groups.
