Fetal programming of body dimensions and percentage body fat measured in prepubertal children with a 4-component model of body composition, dual-energy X-ray absorptiometry, deuterium dilution, densitometry, and skinfold thicknesses.
Intrauterine programming of body composition [percentage body fat (%BF)] has been sparsely examined with multiple independent reference techniques in children. The effects on and consequences of body build (dimensions, mass, and length of body segments) are unclear.
We study this question for a single-spike model, with a
Spike that is $\ell_0$-sparse, and dimension $p$ and sample size $n$ that tend
To infinity. Amini and Wainwright (2009) proved that for sparsity levels
$k\geq\Omega(n/\log p)$, no algorithm, efficient or not, can reliably recover
The sparse eig...
We conducted a content analysis of the 2004-2006 annual reports from the seven participating sites. We used both deductive and inductive approaches to categorise the guideline implementation activities and their resource implications. Results. All sites reported implementing multiple guidelines (...
We prove certain inequalities for mixed discriminants of
Positive semi-definite matrices, and mixed volumes of compact convex sets in
N-dimensions. Moreover, we discuss how the latter are related to the
Monotonicity of an information functional on the class of convex bodies, which
Is a geometric ana...
