Large-head metal-on-metal total hip replacement has a failure rate of almost 8% at five years, three times the revision rate of conventional hip replacement. Unexplained pain remains a feature of this type of arthroplasty. All designs of the femoral component of large-head metal-on-metal total hip replacements share a unique characteristic: a subtended(More)
We present the small-scale (0.01 < r < 8 h −1 Mpc) projected correlation function w p (r p) and real space correlation function ξ(r) of 24520 luminous early-type galaxies from the Sloan Digital Sky Survey Luminous Red Galaxy (LRG) sample (0.16 < z < 0.36). " Fiber collision " incompleteness of the SDSS spectroscopic sample at scales smaller than 55 arcsec(More)
Star-formation history is strongly related to environment; the most massive and least star-forming galaxies reside in the highest density environments. There are now good observational reasons to believe that the progenitors of these red galaxies have undergone starbursts, followed by a post-starburst phase. Post-starburst (" K+A " or " E+A ") galaxies(More)
SDSSJ1049+5103, commonly known as Willman 1, is an extremely low-luminosity Milky Way companion whose properties are intermediate between those of globular clusters and dwarf spheroidals. In this paper, we present new, wide-field photometry extending 3 mag below the main sequence turnoff. These data show that this object is old, moderately metal-poor, has a(More)
We model the small-scale clustering of luminous red galaxies (LRGs; Masjedi et al. 2006) in the Sloan Digital Sky Survey (SDSS). Specifically, we use the halo occupation distribution (HOD) formalism to model the projected two-point correlation function of LRGs on scales well within the sizes of their host halos (0.016h −1 Mpc ≤ r ≤ 0.42h −1 Mpc). We start(More)
