Decadal timescale shift in the ^14C record of a central equatorial Pacific coral
Grottoli, A. G.; Gille, S. T.; Druffel, E. R. M.; Dunbar, R. B. ( 2003 )Coral skeletal radiocarbon records reflect seawater Δ^14C and are useful for reconstructing the history of water mass movement and ventilation in the tropical oceans. Here, we reconstructed the inter-annual variability ... -
A Deep Multicolor Survey. V. The M Dwarf Luminosity Function
Martini, Paul; Osmer, Patrick S. ( 1998-11 )We present a study of M dwarfs discovered in a large-area, multicolor survey. We employ a combination of morphological and color criteria to select M dwarfs to a limiting magnitude in V of 22, the deepest such ground-based ... -
A Deep Multicolor Survey. VI. Near-Infrared Observations, Selection Effects, and Number Counts
Martini, Paul ( 2001-02 )I present near-infrared J (1.25 μm), H (1.65 μm), and K (2.2 μm) imaging observations of 185 arcmin^2 in 21 high galactic latitude fields. These observations reach limiting magnitudes of J ~ 21, H ~ 20, and K ~ 18.5 mag. ... -
A Deep Multicolor Survey. VII. Extremely Red Objects and Galaxy Formation
Martini, Paul ( 2001-05 )Extremely red objects (EROs) offer a window to the universe at z ~ 1 analogous to that provided by the Lyman break galaxies at z = 3. Passive evolution and hierarchical galaxy formation models make very distinct predictions ... -
Dehydration-Induced Loss of Corrosion Protection Properties in Chromate Conversion Coatings on Aluminum Alloy 2024-T3
Laget, V.; Jeffcoate, C. S.; Isaacs, H. S.; Buchheit, R. G. ( 2003-07-17 )It is well known that chromate conversion coatings (CCCs) exhibit a prompt loss in corrosion resistance when exposed to moderately elevated temperatures (60-100°C). They also suffer a gradual loss in corrosion resistance ... -
Delta inflation: a bias in the design of randomized controlled trials in critical care medicine
Aberegg, Scott K.; Richards, D. Roxanne; O'Brien, James M. ( 2010-04-29 )Introduction: Mortality is the most widely accepted outcome measure in randomized controlled trials of therapies for critically ill adults, but most of these trials fail to show a statistically significant mortality ... -
The Dependence of Galaxy Shape on Luminosity and Surface Brightness Profile
Vincent, R. Anthony; Ryden, Barbara S. ( 2005-04-10 )For a sample of 96,951 galaxies from the Sloan Digital Sky Survey Data Release 3, we study the distribution of apparent axis ratios as a function of r-band absolute magnitude and surface brightness profile type. We use the ... -
Design of a laboratory scale bioreactor for treating landfill waste
Myers, M. J.; Christy, A. D.; Tuovinen, O. H. ( 2000-11 )This article documents the design and construction of a laboratory-scale (1.5 m(3)) bioreactor system that can be used to simulate anaerobic microbial processes in landfills. This design has use in feasibility studies of ... -
Designing an Evidence Based Medicine Resource Page to Help Student Pharmacists
Griggs, Michael; Barnette, Debra; Kupferberg, Natalie ( 2015 )Objectives: Develop an online Evidence Based Medicine (EBM) resource page to improve student utilization of EBM. Evaluate potential clinical and educational benefit of resource page by college faculty. Identify perceptions ... -
Detailed Surface Photometry of Dwarf Elliptical and Dwarf S0 Galaxies in the Virgo Cluster
Ryden, Barbara S.; Terndrup, Donald M.; Pogge, Richard W.; Lauer, Tod R. ( 1999-06-01 )We analyze new V-band images of 14 dwarf S0 galaxies and 10 dwarf elliptical galaxies in the Virgo Cluster, in combination with R-band images of 70 dwarf elliptical galaxies from an earlier paper. We compute the ... -
Detecting the Elusive Larkin-Ovchinnikov Modulated Superfluid Phases for Imbalanced Fermi Gases in Optical Lattices
Loh, Yen Lee; Trivedi, Nandini ( 2010-04-22 )A system with unequal populations of up and down fermions may exhibit a Larkin-Ovchinnikov (LO) phase consisting of a periodic arrangement of domain walls where the order parameter changes sign and the excess polarization ... -
Detection Efficiencies of Microlensing Data Sets to Stellar and Planetary Companions
Gaudi, B. Scott; Sackett, Penny D. ( 2000-01-01 )Microlensing light curves are now being monitored with the temporal sampling and photometric precision required to detect small perturbations due to planetary companions of the primary lens. Microlensing is complementary ... -
Detection Rates for Close Binaries via Microlensing
Gaudi, B. Scott; Gould, Andrew ( 1997-06-10 )Microlensing is one of the most promising methods of reconstructing the stellar mass function down to masses even below the hydrogen-burning limit. The fundamental limit to this technique is the presence of unresolved ... -
