The spectrum of a selfadjoint, C∞ linear elliptic partial differential operator on a compact manifold contains only isolated eigenvalues, each having finite multiplicity. It is sometimes the case that ...

Abstract: Hyperspectral image super-resolution aims to reconstruct high-quality spatial–spectral cubes from RGB images. However, the limited spectral coverage of RGB inputs hinders the simultaneous ...

Abstract: Unbalanced DC inductor currents in multilevel current source converters (MCSCs) can degrade power quality and potentially lead to overloading of individual modules or bridge arms.

Editor's note: This is the second in a two-part series about the colorful "Colonel" William C. Greene, who is credited with developing mines in Cananea, Sonora. The years 1899 through 1906 were ...
