OBJECTIVE To verify changes in left ventricular (LV) volumes and regional myocardial wall motion after implantation of a textile cardiac support device (CSD) for passive external constraint in non-ischemic dilated cardiomyopathy. METHODS In nine male patients participating in a non-randomized clinical trial LV volumes were determined and the segmental LV wall motion was studied by contrast-en...

BACKGROUND Early resolution of ST-segment elevation (ST-segment recovery) is associated with an improved outcome after infarction. Whether this relation is present in patients with Thrombolysis In Myocardial Infarction (TIMI) grade 2 or 3 flow (ie, patent) infarct-related arteries is not known. METHODS AND RESULTS To examine the associations between time to achieve stable 50% ST-segment recov...

Kinematic and kinetic foot models showed that computing ankle joint angles, moments power with a one-segment modeling approach alters kinematics tends to overestimate power. Nevertheless, gait studies continue implement assess the effect of total replacement. The objective this pilot study was investigate (one-segment versus multi-segment) on how replacement is estimated benefit or degrade pati...

In this thesis, we present a framework for segmentation of pedestrians in videos. Traditional image segmentation algorithms have relied on learning an appearance model for the regions of interest in an image and using that model to segment new images. However, large variations in the appearance of pedestrians due to differences in clothing makes it impossible to learn a reliable appearance mode...

Imitation learning is a powerful approach to humanoid behavior generation, however, the most existing methods assume the availability of the information on the internal state of a demonstrator such as joint angles, while humans usually cannot directly access to imitate the observed behavior. This paper presents a method of imitation learning based on visuosomatic mapping from observing the demo...

BACKGROUND In vitro investigations have demonstrated the importance of the ribcage in stabilizing the thoracic spine. Surgical alterations of the ribcage may change load-sharing patterns in the thoracic spine. Computer models are used in this study to explore the effect of surgical disruption of the rib-vertebrae connections on ligament load-sharing in the thoracic spine. METHODS A finite ele...

Using an instrumented spatial linkage, a method for measuring intervertebral motion in vivo was developed and used on six dogs. The segmental motion was recorded as the animals were exercised in routine functions. The standing posture was found to be a repeatable position. During walking, the average excursion between opposing facets was 3.4 +/- 1.3 mm, as the L2-L3 motion segment moved into 2....
