We analyze the structure of supersymmetric Gödel-like cosmological solutions of string theory. Just as the original four-dimensional Gödel universe, these solutions represent rotating, topologically trivial cosmologies with a homogeneous metric and closed timelike curves. First we focus on “phenomenological” aspects of holography, and identify the preferred(More)
Light is a powerful tool for manipulating microscopic objects. It can control the position and orientation of objects as large as 100 mm and as small as a single atom. Light force, in the form of single beam gradient force traps, has been used to trap and manipulate dielectric spheres, viruses, bacteria, living cells, organelles, colloidal gold, and even(More)
Quantum annealing is an experimental and potentially breakthrough computational technology for handling hard optimization problems, including problems of computer vision. We present a case study in training a production-scale classifier of tree cover in remote sensing imagery, using early-generation quantum annealing hardware built by D-wave Systems, Inc.(More)
We present an algorithm capable of identifying a wide variety of human-induced change on the surface of the planet by analyzing matches between local features in time-sequenced remote sensing imagery. We evaluate feature sets, match protocols, and the statistical modeling of feature matches. With application of KAZE features, k-nearest-neighbor descriptor(More)
