We present a wireless virtual reality system and a prototype full body Tai Chi training application. Our primary contribution is the creation of a virtual reality system that tracks the full body in a working volume of 4 meters by 5 meters by 2.3 meters high to produce an animated representation of the user with 42 degrees of freedom. This – combined with a(More)
The tropomyosin I(TmI) gene of Drosophila melanogaster encodes two isoforms of tropomyosin. The Ifm-TmI isoform is expressed only in indirect flight and jump muscles; the Scm-TmI isoform is found in other muscles of the larva and adult. The level of Ifm-TmI is severely reduced in the flightless mutant Ifm(3)3, which also is unable to jump. To explore the(More)
Context. Observations of the Sunyaev-Zel'dovich effect (SZE) from galaxy clusters are emerging as a powerful tool in cosmology. Besides large cluster surveys, resolved SZE images of individual clusters can shed light on the physics of the intra-cluster medium (ICM) and allow accurate measurements of the cluster gas and total masses. Aims. We used the(More)
APECS is the distributed control system of the new Atacama Pathfinder EXperiment (APEX) telescope located on the Llano de Chajnantor at an altitude of 5107 m in the Atacama desert in northern Chile. APECS is based on Atacama Large Millimeter Array (ALMA) software and employs a modern, object-oriented design using the Common Object Request Broker(More)
We present measurements of the angular power spectrum of millimeter wave anisotropies with the APEX-SZ instrument. APEX-SZ has mapped 0.8 square degrees of sky at a frequency of 150 GHz with an angular resolution of 1. These new measurements significantly improve the constraints on anisotropy power at 150 GHz over the range of angular multipoles 3000 < <(More)
We present observations of the Sunyaev-Zel'dovich effect (SZE) in the Bullet cluster (1E 0657–56) using the APEX-SZ instrument at 150 GHz with a resolution of 1. The main results are maps of the SZE in this massive, merging galaxy cluster. The cluster is detected with 23 σ significance within the central 1 radius of the source position. The SZE map has a(More)
We present a wireless virtual reality system and MasterMotion, the full-body training application built with it. We combine realtime full-body optical motion capture with wireless audio/video broadcast, belt-worn electronics, and a lightweight head-mounted display (HMD), to provide a wide-area, untethered virtual environment system that allows exploration(More)
