The Langlands program has inspired and befuddled mathematicians for more than 50 years. A major advance has now opened up new ...

Particles and antiparticles have opposite charges, and they annihilate if they interact, turning into pure energy. In the Big ...

Ethical clarity arises not from rules, but from attention to what is unfolding. Imagination and empathy are core tools for ...

Researchers have cracked a fundamental optical challenge: how to control both angle and wavelength of light independently—a ...

This paper presents a new symmetry-integrated region-based image segmentation method. The method is developed to obtain improved image segmentation by exploiting image symmetry. It is realized by ...

Feature detection on smooth free-form surfaces is much more difficult than that on shapes with sharp features. In this paper, we extract the curved reflection axes (CRAs) of an arbitrary free-form ...
