"My former colleague at Penn State, Sven Bilén, is an expert in electromagnetics. I showed him some origami structures I'd been working on a few years ago. He was intrigued and asked if origami could ...

The RNA world hypothesis implies that coded protein synthesis evolved from a set of ribozyme catalyzed acyl-transfer reactions, including those of aminoacyl-tRNA synthetase ribozymes. We report here ...

Box pleating is arguably the standard framework of modern super-complex origami designs, as the creases are much more predictable and manageable than those found in the traditional 22.5 degree system ...

Abstract: In this paper, a horizontally polarized UWB antenna is proposed. The UWB nature of the antenna is achieved using a stepped impedance microstrip feed line to excite the stepped slot ...

Abstract: This paper presents a theoretical model of the rectangular-shaped microstrip patch antennas on liquid crystal (LC) substrates in order to accurately derive the resonant frequencies and ...
