Advanced traffic management systems allow video image detection to supplement and improve data inputs in transportation modeling efforts. Video detection systems use machine vision technology, the interaction of video cameras, and specialty computer hardware and software to measure traffic. Traffic parameters such as hourly flows, density, vehicle speed,(More)
Visual illusions often appear to have a larger influence on subjective judgments than on visuomotor behavior. Although this effect has been taken as evidence for multiple estimates of stimulus size in the visual brain, dissociations between subjective judgments and visuomotor measures can frequently be reconciled with a single-estimate model. To circumvent(More)
(2007). Feedback control in active sensing: rat exploratory whisking is modulated by environmental contact. The aim is to augment human navigation with 'virtual whiskers' which can support obstacle avoidance in low light and/or by the visually impaired. Our inspiration is the w h i s k e r (v i b r i s s a l) system which we have studied in animals and(More)
Hydraulic fracturing and horizontal drilling have increased dramatically in Pennsylvania Marcellus shale formations, however the potential for major environmental impacts are still incompletely understood. High-throughput sequencing of the 16S rRNA gene was performed to characterize the microbial community structure of water, sediment, bryophyte, and(More)
A 61-year-old right-handed man presented for cognitive neurological evaluation with word-finding difficulty, impaired word retrieval, impaired repetition of phrases, and stammering. Brain MRI and FDG-PET/CT were performed as initial imaging workup. Further FDG PET/MRI brain images were obtained through software fusion and revealed regional cortical atrophy(More)
BACKGROUND Prior studies of physical functioning after critical illness have been mostly limited to survivors of acute respiratory distress syndrome. The purpose of this study was to objectively assess muscle strength and physical functioning in survivors of critical illness from a general ICU and the associations of these measures to health-related quality(More)
