Lockheed F-104 Starfighter was a Mach 2 interceptor known for its unique design and record-setting performance before ending ...

Welcome to MythBusters, a Golf Digest+ series where we explore answers to some of golf’s most common questions through a series of tests with golfers and robots. Sometimes definitive, other times less ...

Demonstrate that if two trihedral angles have dihedral angles respectively equal, then their face angles are equal. For 15 years Columbia’s Dean Herbert Edwin Hawkes has dangled this poser before his ...

Here we use the 1,3-propanediol molecule as an example, scanning the 10 1 4 7 dihedral while keeping the 12 7 4 1 dihedral frozen to avoid energy jumps. Note that the initial geometry of the scan ...

Structural biology, biochemistry, evolutionary biology, medicine, and drug development all require high-quality protein structures. Reliable tools for assessing structures remain essential to ensure ...

Abstract: Resolving multipath artifacts in concave objects is one of the keys to the development of millimeter-wave (mmW) security imaging. This article deals with the multipath artifacts problem of ...

Abstract: Dihedral is a common structure in polarimetric SAR images and can be found on many man-made targets. Many researchers have proposed different dihedral models, but the accuracy of these ...

A large-scale analysis of high-resolution protein structures suggests that amino acid pairs constitute another layer of ordered structure, more local than the conventionally defined secondary ...

Every disease has a protein basis. For some diseases, like HIV, changes in protein structure are critical for how the virus infects a person’s cells. Researchers at the University of Illinois Chicago ...
