Once you take your new shoes out of the box, you probably never think about that piece of cardboard again. But why not reuse ...

"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 ...

"Because the most common electromagnetic waveguides are rectangular-shaped, our origami designs needed to maintain a rectangular cross section in the operational state for comparable performance." ...

In an EM wave absorbent chamber, an LED is illuminated at 10 cm by microwave energy delivered through a twist bellows waveguide. Scale bar is 100 mm. The inserts upper left show the twist bellows ...

High-powered satellites use electromagnetic waveguides to deliver energy from one component to another. Typically, they are made of heavy, inflexible metal tubes with an even heavier flange on either ...

Abstract: As a promising modulation scheme for high mobility wireless communications, orthogonal time frequency space (OTFS) has received tremendous attention. In the case of bi-orthogonal waveforms, ...

In computer vision, document layout analysis is the process of identifying and categorizing the regions of interest in the scanned image of a text document. A reading system requires the segmentation ...

Abstract: The interface of computer technologies and biology is having a huge impact on society. Human recognition research projects promises new life to many security-consulting firms and personal ...

Scientists have developed a method to protect DNA origami structures from decomposition in biological media. This protection enables future applications in nanomedicine or cell biology.
