In Praise of Fault Tolerant Systems " Fault attacks have recently become a serious concern in the smart card industry. " Fault Tolerant Systems " provides the reader with a clear exposition of these attacks and the protection strategies that can be used to thwart them. A must read for practitioners and researchers working in the field. " David Naccache,(More)

Examining a sample of massive galaxies at 1.4 < z < 2.5, we present a systematic intercomparison of pho-tometry at various wavelengths that are sensitive to energy from star formation, in order to examine the degree to which different tracers do or do not agree, and to explore the implications for star formation and galaxy assembly. We use some of the(More)
UNLABELLED Using computational fluid dynamics simulations of an occupant in a ventilated room, we find that breathing zone ozone levels can be substantially lower and ozone reaction products associated with human surfaces (ORPHS) levels considerably higher than room levels. For air exchange rates <3/h, the ratio of the breathing zone to the ozone(More)
We present the serendipitous discovery of molecular gas CO emission lines with the IRAM Plateau de Bure interferometer coincident with two luminous submillimeter galaxies (SMGs) in the Great Observatories Origins Deep Survey North field (GOODS-N). The identification of the millimeter emission lines as CO[4-3] at z = 4.05 is based on the optical and near-IR(More)
We investigate the multi-wavelength emission of BzK selected star forming galaxies at z ∼ 2 in the Great Observatories Origins Deep Survey (GOODS) North region. Most (82%) of the sources are individually detected at 24µm in the Spitzer MIPS imaging, and one fourth (26%) in the VLA radio data. Significant detections of the individually undetected objects are(More)
We present the first detection of molecular gas cooling CO emission lines from ordinary massive galaxies at z = 1.5. Two sources were observed with the IRAM Plateau de Bure Interferometer, selected to lie in the mass-star formation rate correlation at their redshift, thus being representative of massive high-z galaxies. Both sources were detected with high(More)
We investigate the nature of a population of z ∼ 2 galaxies that shows a distinct mid-IR excess flux density at 24 µm with respect to that expected from the star formation rate as estimated at radio, UV, 70 µm, soft X-ray, and submm wavelengths. These mid-IR excess galaxies, identified in the Great Observatories Origins Deep Survey (GOODS), represent ≈(More)

We present deep Spitzer mid-infrared spectroscopy, along with 16, 24, 70, and 850 µm photometry, for 22 galaxies located in the Great Observatories Origins Deep Survey-North (GOODS-N) field. The sample spans a redshift range of 0.6 z 2.6, 24 µm flux densities between ∼0.2−1.2 mJy, and consists of submillimeter galaxies (SMGs), X-ray or optically selected(More)
