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,...

INTRODUCTION A few electrocardiographic criteria have been described to identify the infarct-related artery in inferior myocardial infarction. The aim of this study was to devise an arithmetic score to further improve the diagnostic accuracy. MATERIALS AND METHODS From 2004 to 2006, 78 patients who underwent primary angioplasty for inferior myocardial infarction within 6 hours from symptom on...

Vascular occlusions are common structural modifications made by many plant species in response to pathogen infection. However, the functional role(s) of occlusions in host plant disease resistance/susceptibility remains controversial. This study focuses on vascular occlusions that form in stem secondary xylem of grapevines (Vitis vinifera) infected with Pierce's disease (PD) and the impact of o...

BACKGROUND Effects of systolic left ventricular pressure (LVP) on rates of pressure fall remain incompletely understood. This study analyzed phase-plane dP/dt versus LVP plots to differentiate between accelerating and decelerating effects and to investigate the variability in reported load effects on rates of LVP fall. METHODS AND RESULTS Abrupt aortic occlusions were performed by inflating a...
