BACKGROUND The Reynolds Risk Score (RRS) is one alternative to the Framingham Risk Score (FRS) for cardiovascular risk assessment. The Adult Treatment Panel III (ATP III) integrated the FRS a decade ago, but with the anticipated release of ATP IV, it remains uncertain how and which risk models will be integrated into the recommendations. We sought to define the effects in the United States popu...

We report on the study of the low temperature resonant Raman scattering (RRS) in G ~ A S / A ~ , ~ ~ G Q . ~ ~ A S Bragg confining structures (BCS). The LO-phonon RRS is observed in the spectral range of the (eB : hhB) and ( e ~ : l h ~ ) Bragg confined excitons. The RRS profiles show an outgoing beam resonance that is much stronger than the incoming beam resonance. These profiles are analyzed ...

A theoretical concept of resonant Rayleigh scattering (RRS) of exciton-polaritons in multiple quantum wells (QWs) is presented. The optical coupling between excitons in different QWs can strongly affect the RRS dynamics, giving rise to characteristic temporal oscillations on a picosecond scale. Bragg and anti-Bragg arranged QW structures with the same excitonic parameters are predicted to have ...

We report on the first high-resolution measurements of the K x-ray resonant Raman scattering (RRS) in Si. The measured x-ray RRS spectra, interpreted using the Kramers-Heisenberg approach, revealed spectral features corresponding to electronic excitations to the conduction and valence bands in silicon. The total cross sections for the x-ray RRS at the 1s absorption edge and the 1s-3p excitation...

Observations concerning the action of lysozyme on Bacillus megaterium have been suggestive, although not conclusive, in indicating that the bacterial cell wall is lysed (Welshimer and Robinow, 1949). Recently Tomesik and GuexHolzer (1952) have supported this contention by a combination of immuno-chemical procedures and phase contrast microscopy. In the experimental work here reported, a differe...

Rapid Response System (RRS) is by now commonly used and internationally validate to manage in hospital emergency. Both its optimal management and early identification are essential to reduce mortality and neurological sequences of anoxia. However, in the pediatric Italian population, this system is poorly employ, even if its effectiveness has already been demonstrated. Therefore, in 2010 at Tur...

BACKGROUND Objective biomarkers are needed to assess adherence to vegetable and fruit intervention trials. Blood carotenoids are considered the best biomarker of vegetable and fruit intake, but collecting blood is invasive and the analyses are relatively expensive for population studies. Resonance Raman spectroscopy (RRS) is an innovative method for assessing carotenoids in skin noninvasively. ...

Resonant Raman spectroscopy (RRS) is a very useful tool to study physical properties of materials since it provides information about excitons and their coupling with phonons. We present in this work a RRS study of samples of WSe2 with one, two, and three layers (1L, 2L, and 3L), as well as bulk 2H-WSe2, using up to 20 different laser lines covering the visible range. The first- and second-orde...
