The present study focuses on the development of a general framework for propagating the effects of parametric uncertainty, modeled as random fields, from input to output for complex engineering systems via Stochastic Finite Element techniques. These techniques are similar in concept to deterministic finite element approaches in that they approximate both input and output quantities in terms of ...

Background—Prior studies of coronary pattern and outcome after arterial switch operation (ASO) for transposition of the great arteries (TGA) have been hindered by limited statistical power. This meta-analysis assesses the effect of coronary anatomy on post-ASO mortality, both overall and adjusted for time. Methods and Results—A literature search revealed 9 independent series that reported post-...

BACKGROUND The beneficial effect of physical activity for the prevention of a range of chronic diseases is widely acknowledged. These chronic conditions are most pronounced in economically disadvantaged groups where physical activity levels are consistently lower, yet this group is particularly difficult to recruit and retain in physical activity programmes. This study examined the perceptions ...
