Totally Occluded Arteries
The potential application of ultrasonic energy for ablation of atherosclerotic plaques was studied in human atherosclerotic arteries with continuous and pulsed delivery of energy. With a prototype ultrasonic wire probe (n=79 segments), there was gross reduction in vascular lesions as well as microscopic disruption of fibrous and calcified plaques. Normal portions of vessels appeared unaffected ...
متن کاملCerebral Artery-Occluded Rats
We evaluated the influence of a continuous intravenous infusion of 0.24 mg/kg PN 200-110 started 20 minutes before the induction of ischemia and continued for 2 hours on infarct size, histopathology, and neurological outcome in middle cerebral artery-occluded rats treated with PN 200-110 (n=8), placebo (n=7), or saline (n=8). Neurological examination was performed 24 hours after occlusion. We q...
متن کاملOccluded Facial Expression Tracking
The work presented here takes place in the field of computer aided analysis of facial expressions displayed in sign language videos. We use Active Appearance Models to model a face and its variations of shape and texture caused by expressions. The inverse compositional algorithm is used to accurately fit an AAM to the face seen on each video frame. In the context of sign language communication,...
متن کاملRecognition of Occluded Objects
3 Pattern recognition involves building a mental model to interpret incoming inputs. 4 This incoming information is often incomplete and the mental model must 5 extrapolate to complete the patterns, a process that is constrained by the statistical 6 regularities in nature. Examples of pattern completion involve identification of 7 objects presented under unfavorable luminance or interpretation ...
متن کاملPartly Occluded Objects
Newborn infants were familiarized to a three-dimensional display consisting of a rod which moved behind a central occluder, so that , only the top and bottom of the rod were visible. The infants’ eyes were 38 cm from the rod and the occluder was 15 cm in front of the rod, a separation intended to ensure that the gap between the two was detected by the infants. On subsequent test trials the infa...
