To examine incidence and predictors of employment stability in veterans and military service members with traumatic brain injury (TBI) who return to work.Prospective observational cohort study.Four rehabilitation centers.Veterans and military service members (N=110) with mild (26%), moderate (22%), or severe (52%) TBI enrolled in the Department of Veterans Affairs Polytrauma Rehabilitation Centers...
We report radar observations of Apophis obtained during the 2012−2013 apparition. We observed Apophis on fourteen days at Goldstone (8560 MHz, 3.5 cm) and on five days at Arecibo (2380 MHz, 12.3 cm) between 2012 December 21 to 2013 March 16. Closest approach occurred on January 9 at a distance of 0.097 au. We obtained relatively weak echo power spectra and delay-Doppler images. The highest range resolution...
We report radar and optical photometric observations of near-Earth asteroid (214869) 2007 PA8 obtained during October 2–November 13, 2012. We observed 2007 PA8 on sixteen days with Goldstone (8560MHz, 3.5cm) and on five days with the 0.6m telescope at Table Mountain Observatory. Closest approach was on November 5 at a distance of 0.043au. Images obtained with Goldstone's new chirp system achieved...
Sleep problems and disorders are prevalent in patients with traumatic brain injury (TBI) and are associated with negative outcomes. Incidence varies because of challenges including differences in assessment methods, particularly in the acute stages of recovery when patients are cognitively impaired and unable to complete traditional self-report methods. Actigraphy (ACG) recently has been validated...
