One can check that, whatever q~, the high frequency filling factor F~(a, b) is better than the low frequency one Fo(a, b), This fact can be easily understood : the mean radius of

This design, which has never been used for gamma-ray space telescopes, maintains the advantages of a Compton telescope (high-energy response, low background, wide field of view)

A combination of SNPS is associated with the postprandial chylomicron triacylglycerol response in healthy male adults Charles Desmarchelier, Jean-Charles Martin, Richard

In this note we verify certain statement of Donaldson about the operator Q K in Section 4.2 by using the full asymptotic expansion of Bergman kernel derived in [2, Theorem 4.18] and

In contrast, very little change in AIF expression levels or localiza- tion is observed upon treatment with L H (see Fig. S22† for quantication of nuclear localization),

The authors found that survival in CPFE was better than that of patients with idiopathic pulmonary fibrosis (IPF) without emphysema or with minimally extensive emphysema ( ’

The arrangement of the stages, each of which designed to detect at a different wavelength, was chosen in such a way as to guarantee a flow of electrons from higher lying toward

The most copious background, B → J/ψX , is eliminated by requiring the J/ψ mo- mentum in the CM frame ( p ∗ ) to be greater than 2 GeV/c , above the kinematic limit for B decays ( B
