This article presents a novel data-driven framework for constructing eigenfunctions of the Koopman operator geared toward prediction and control. The method leverages the richness of the spectrum of ...

The technique to integrate the composite hermitian operator eigenfunctions (CHOEs) with the general asymptotic waveform evaluation (GAWE) is proposed for computing the radar cross section (RCS) of a ...

The two most important developments in nuclear physics were the shell model and the collective model. The former gives the formal framework for a description of nuclei in terms of interacting neutrons ...

The description of the band gap of halide perovskites at the level of density functional theory (DFT) has been subject of several studies but still presents significant problems and deviations from ...
