Watching TV has been consistently associated with higher risk of adverse health outcomes, but the effect of other sedentary behaviors (SB) is uncertain. Potential explanations are that watching TV is not a marker of a broader sedentary pattern and that each SB reflects different sociodemographic and health characteristics. Data were taken form a survey on 10,199 individuals, representative of t...

BACKGROUND Patients who have undergone cardiac surgery are generally mechanically ventilated postoperatively. Early postoperative extubation is currently recommended in anesthesia guidelines. No current technology can accurately, non-invasively, measure respiratory competence after extubation. Pulse oximetry has been helpful, but this is a late indicator of respiratory compromise. A novel, non-...

Preclinical in vivo micro computerized tomography suffers from high image noise, due to limitations on total scanning time and the small pixel sizes. A lot of different noise minimization algorithms have already been proposed to reconstruct images acquired in low dose settings. Sparse-view reconstruction amongst others can reduce acquisition dose significantly, by acquiring only a small subset ...

Inhabited TV combines collaborative virtual environments (CVEs) with broadcast TV so that on-line audiences can participate in TV shows within shared virtual worlds. Three early experiments with inhabited TV raised fundamental questions concerning the extent to which it is possible to establish fast-pace social interaction within a CVE and produce a coherent and engaging broadcast of this actio...

Stereoscopic 3D TV viewing puts different visual demands on the viewer compared to 2D TV viewing. Previous research has reported on viewers’ fatigue and discomfort and other negative effects. This study is to investigate further how severe and what symptoms may arise from somewhat longish 3D TV viewing. The MPEG 3DV project is working on the next-generation video encoding standard and in this p...

BACKGROUND Accumulating evidence suggests that television (TV) viewing is associated with cardio-metabolic risk, but little is known about how this relationship unfolds over the life course. This study employs a life course epidemiological framework by examining the potential cumulative effect of frequent TV viewing during adolescence and young adulthood on the prevalence of metabolic syndrome ...
