Alzheimer's disease (AD) is characterized by neuronal cell death and atrophy in regions of the adult brain, including the hippocampus and cortex, due to formation of amyloid beta (Aβ) plaques and neurofibrillary tangles. The presence of these pathologies can limit normal signaling properties and ultimately lead to learning and memory deficits. Chronic(More)
We investigate the influence of using IGS predicted orbits for near real-time zenith tropospheric delay determination from GPS and implement a new processing strategy that allows the use of predicted orbits with minimal degradation of the ZTD estimates. Our strategy is based on the estimation of the three Keplerian parameters that represent the main error(More)
OBJECTIVE Despite the current prevalence of preterm births, no clear guidelines exist on the optimal mode of delivery. Our objective was to investigate the effects of mode of delivery on neonatal outcomes among premature infants in a large cohort. STUDY DESIGN We applied a retrospective cohort study design to a database of 6,408 births. Neonates were(More)
