Gravitational Wave Detection With Single-Laser Atom Interferometers

A new design for a broadband detector of gravitational radiation relies on two atom interferometers separated by a distance L. In this scheme, only one arm and one laser are used for operating the two atom interferometers. The innovation here involves the fact that the atoms in...

Algorithm for Autonomous Landing

Because of their small size, high maneuverability, and easy deployment, micro aerial vehicles (MAVs) are used for a wide variety of both civilian and military missions. One of their current drawbacks is the vast array of sensors

(such as GPS, altimeter, radar, and the like) required to make a landing. Due...

Ideally, the concept of "on demand" shouldn't limit itself to pay-per-view movies. If 3D printers were widely available in every household, consumers could quickly "demand" and fabricate specialized food and other objects at the touch of a button. Scientists in the emerging field of "bioprinting" are even attempting to make it...
