A passive nonlinear digital filter design which facilitates physics-based sound synthesis of highly nonlinear musical instruments
Recent work has led to highly efficient physics-based computational models of wave propagation in strings, acoustic tubes, membranes, plates, and rooms using the digital waveguide filter, the 2-D digital waveguide mesh, ... -
Periodicity and pitch perception
There has been experimental evidence pointing to at least two pitch mechanisms, the first involving low-order harmonics that are resolved along the basilar membrane, and the second a periodicity mechanism that depends only ... -
Effects of rapid thermal annealing on the optical properties of low-loss 1.3 mu m GaInNAs/GaAs saturable Bragg reflectors
We report studies of the effect of rapid thermal annealing (RTA) on the optical properties of a low-loss 1.3 mum saturable Bragg reflector (SBR), consisting of a GaInNAs/GaAs single quantum well embedded in an AlAs/GaAs ... -

The Hubble Deep Field North SCUBA Super-map - I. Submillimetre maps, sources and number counts
We investigate the emission of submillimetre-wave radiation from galaxies in a 165 arcmin<SUP>2</SUP> region surrounding the Hubble Deep Field North. The data were obtained from dedicated observing runs from our group and ... -
The SCUBA Half Degree Extragalactic Survey (SHADES) - IX. The environment, mass and redshift dependence of star formation
We present a comparison between the SCUBA (Submillimetre Common User Bolometer Array) Half Degree Extragalactic Survey (SHADES) at 450 and 850 in the Lockman Hole East with a deep Spitzer Space Telescope survey at 3.6 ... -
THE LARGE APEX BOLOMETER CAMERA SURVEY OF THE EXTENDED CHANDRA DEEP FIELD SOUTH

The SCUBA Half-Degree Extragalactic Survey - I. Survey motivation, design and data processing
The Submillimetre Common-User Bolometer Array (SCUBA) Half-Degree Extragalactic Survey (SHADES) is a major new blank-field extragalactic submillimetre (submm) survey currently underway at the James Clerk Maxwell Telescope ... -
A Mid-Infrared Imaging Survey of Submillimeter-Selected Galaxies with the Spitzer Space Telescope
We present <I>Spitzer</I>-IRAC and MIPS mid-IR observations of a sample of 73 radio-detected submillimeter-selected galaxies (SMGs) with spectroscopic redshifts, the largest such sample published to date. From our data, ... -

Submillimetre Detection of the z=2.83 Lyman-Break Galaxy, Westphal-MM8, and Implications for SCUBA2
We present confusion limited submillimetre (submm) observations with the SCUBA camera on the JCMT of the z=2.83 Lyman-break galaxy (LBG), Westphal-MM8, reaching an 850um sensitivity even greater than that achieved in the ... -
Understanding the nature of the optically faint radio sources and their connection to the submillimeter population
We present a sample of 43 submillimeter sources detected (at >3 sigma), drawn from our program to follow-up optically faint radio sources with SCUBA. These sources already have associated radio and in many cases optical ... -
Adaptive optics near-IR imaging of NGC2992 - unveiling core structures related to radio figure-8 loops
We present near-IR adaptive optics, VLA radio and HST optical imaging of the nearby Seyfert galaxy NGC2992. Spiral structure and an extension to the West are traced down to the core region at the limiting resolution of our ... -
Near-IR adaptive optics imaging of nuclear spiral structure in the Seyfert galaxy, NGC3227
We present high spatial resolution, near-IR images in J, H, K of the nucleus of NGC3227, obtained with the Adaptive Optics bonnette on CFHT. The ~0.15 arcsec (17pc) resolution allows structures to be probed in the core ... -
Search For Trapped Antihydrogen
We present the results of an experiment to search for trapped antihydrogen atoms with the ALPHA antihydrogen trap at the CERN Antiproton Decelerator. Sensitive diagnostics of the temperatures, sizes, and densities of the ... -
The Far- and Mid-Infrared/Radio Correlations in the Spitzer Extragalactic First Look Survey
Using the SPITZER SPACE TELESCOPE and the VLA, we present the first DIRECT evidence that the well-known far-infrared/radio correlation is valid to cosmologically significant redshift. We also confirm, with improved statistics ...
