We directly demonstrate an improvement in the radiative decay rate of dye molecules near multilayer hyperbolic metamaterials (HMMs). Our comprehensive study shows a radiative decay rate for rhodamine 800 (Rh800) that is several times higher due to the use of HMM samples as compared to dielectric substrates. This is also the first experimental demonstration that multilayer hyperbolic metamateria...

The 5-HT1B/D receptor agonist sumatriptan has been proposed to treat dyspeptic symptoms, because it facilitates gastric accommodation. It is unknown whether stimulation of 5-HT1B/D receptors is involved. Thus, in four conscious dogs, we compared the effects of sumatriptan alone or combined with N-[4-methoxy-3-(4-methyl-1-piperazinyl) phenyl]-2'-methyl-4'-(5-methyl-1,2,4-oxadiazol-3-yl)-[1,1-bip...

The effects of growth rate (Gr), deposition temperature (Td), film thickness (tF ), and substrate induced strain (ǫ) on morphological, crystallographic and magnetic characteristics of equiatomic CoPt epitaxial films synthesized with pulsed laser deposition (PLD) are investigated. The (001) oriented single crystal substrates of MgO, SrTiO3 and LaAlO3 provide different degree of epitaxial strain ...

Stratification and estimated paleoflow conditions for valley-fill deposits suggest that Ogallala Group streams in western Nebraska were similar to modem streams of south-central Alberta. Ogallala stratification includes medium-scale (0.5 to 2. O m thick) trough crossbedded sand and gravel, tabular indistinctly horizontally bedded and imbricated gravel, and horizontally bedded sand and pebbly sa...
