Synthetic suburethral slings have recently become popular despite the risk of erosion commonly associated with synthetic implants. Some of these materials seem to have unexpectedly low erosion rates. Based on the hypothesis that erosion is due, in part, to biomechanical properties, we undertook an in vitro study. The biomechanical properties of eight(More)

OBJECTIVE Pulse oximetry screening of asymptomatic newborns is suggested as a life-saving procedure for the timely detection of critical congenital heart disease (CHD) in asymptomatic newborns. We evaluated this screening and report cases that demonstrate problems with screening in a non-research setting. STUDY DESIGN An elective state-directed public(More)
Fourteen pairs of explanted low contact stress (LCS) tibial interface components: six rotating platform (RP), six meniscal (MN) and two anterior-posterior (AP) glide designs, have been analysed with particular attention paid to the condition of the tibial counterfaces. The average surface roughness, Ra, for the tibial trays ranged from 0.01 to 0.087 micron,(More)
We forecast high resolution solar irradiance time series using an exponential smoothing state space (ESSS) model. To stationarize the irradiance data before applying linear time series models, we propose a novel Fourier trend model and compare the performance with other popular trend models using residual analysis and the Kwiatkowski-Phillips-Schmidt-Shin(More)
We present fully-sampled maps of 461 GHz CO (• 3 < b < 0. • 2 with 0.5 ′ spacing, resulting in spectra in 3 transitions at over 24,000 positions on the sky. The CO (J = 4 → 3) emission is found to be essentially coextensive with lower-J transitions of CO. The CO (J = 7 → 6) emission is spatially confined to a far smaller region than the lower-J CO lines.(More)
The cold, dry and stable air above the summits of the Antarctic plateau provides the best ground-based observing conditions from optical to sub-mm wavelengths to be found on the Earth. PILOT is a proposed 2 m telescope, to be built at Dome C in Antarctica, able to exploit these conditions for conducting astronomy at optical and infrared wavelengths. While(More)
We present the results of 12 CO J = 2 → 1 observations of the X-ray bright giant shell complex 30 Doradus in the Large Magellanic Cloud (LMC) using the Antarctic Submillimeter Telescope and Remote Observatory (AST/RO). This is the one of the largest H II complexes in the Local Group. We compare the 12 CO J = 2 → 1 observations against previously taken 12 CO(More)
A key project of the Antarctic Submillimeter Telescope and Remote Observatory reported by Martin et al. (2004) is the mapping of CO J = 4 → 3 and J = 7 → 6 emission from the inner Milky Way, allowing determination of gas density and temperature. Galactic center gas that Binney et al. (1991) identify as being on x 2 orbits has a density near 10 3.5 cm −3 ,(More)
OBJECTIVE The purpose of this study was to evaluate the relationship between intraventricular hemorrhage (IVH), inter-hospital transport and known potential risk factors for IVH. STUDY DESIGN Very low birth weight (VLBW <1500 g) infants admitted to a large regional neonatal intensive care unit within 48 h of life from 2005 to 2010 were identified.(More)
