By carefully placing nanostructures on a flat surface, researchers have significantly improved the performance of so-called optical metasurfaces in conductive plastics. This is a major step for ...

Linköping University researchers achieve a tenfold performance boost in conductive polymer metasurfaces, advancing the field ...

By carefully placing nanostructures on a flat surface, researchers at Linköping University, Sweden, have significantly ...

Abstract: We introduce the log-$h$ -convex concept for the interval-valued functions (IVFs) and establish some of the new Jensen’s, Hadamard’s, and Hadamard ...

Abstract: A novel optimization method is proposed to minimize a convex function subject to bilinear matrix inequality (BMI) constraints. The key idea is to decompose the bilinear mapping as a ...

Are flat pedals better if the platform is convex? Concave? Why not both? While the internet argues about which pedal design provides the best grip and feel, OneUp has been testing prototypes of their ...
