Over clear ocean waters, photons scattered within the water body contribute significantly to the upwelling flux. In addition to elastic scattering, inelastic Vibrational Raman Scattering (VRS) by liquid water is also playing a role and can have a strong impact on the spectral distribution of the outgoing radiance. Under clear-sky conditions, VRS has 5 an influence on trace gas retrievals from s...

In this document, the Commission adopts further measures to improve the structure, efficiency, and quality of the video relay service (VRS) program, reducing the inefficiencies in the program, as well as reducing the risk of waste, fraud, and abuse, and ensuring that the program makes full use of advances in commercially-available technology. These measures involve a fundamental restructuring o...

The Virchow-Robin spaces (VRS), perivascular compartments surrounding small blood vessels as they penetrate the brain parenchyma, are increasingly recognized for their role in leucocyte trafficking as well as for their potential to modulate immune responses. In the present study, we investigated VRS numbers and volumes in different brain regions in 45 multiple sclerosis patients and 30 healthy ...

Virchow-Robin spaces (VRS) are perivascular spaces surrounding the perforating cerebral arteries or arterioles.1,2 They distribute throughout the subarachnoid space to the brain parenchyma. Solutes from the brain parenchyma and lymphatics are drained into VRS, but VRS themselves do not have direct communication with the subarachnoid space.3 Dilated VRS (dVRS) are easily detectable by magnetic r...

We theoretically demonstrate the influence of dark and bright states on vacuum Rabi splitting (VRS) and optical bistability (OB) of the multi-wave-mixing (MWM) process in a collective four-level atomic-cavity coupling system. We numerically investigate the multidressed VRS and OB behavior of the zeroand high-order transmitted cavity modes of MWM signals. A further study demonstrates that VRS an...

This paper examines the problems of applying traditional function points count rules to virtual reality systems (VRS). From the analysis of the differences between traditional and VRS systems, a set of deficiencies in the IFPUG 4.1 function points count method was detected. Due to the increasing importance of these kinds of applications, it is necessary to study how traditional function points ...

We compared computed tomographic virtual rhinosinus endoscopy (VRS) and conventional fiberoptic endoscopy (FE) for the detection of inflammatory-obstructive rhinosinusal disease. We recruited 158 patients; 100 (group A) had inflammatory-obstructive rhinosinus disease, and 58 (group B) had a history of rhinosinus surgery. All patients underwent VRS within 2 to 6 hours of FE, and VRS was able to ...

BACKGROUND AND PURPOSE Virchow-Robin spaces (VRSs) are CSF spaces that accompany blood vessels as they perforate the brain substance. Dilatation of VRS is associated with microangiopathy. Microvascular disease has a major etiologic and pathogenetic role in dementias. To our knowledge, no investigators have looked at the relationship between dilated VRS on MR imaging and cerebral microvascular d...

Social cognitive theory is often implemented when researchers develop treatments and campaigns for health behavior change. Immersive virtual environment technology (IVET) enables novel explorations of health behavior modeling. In Study 1, participants were randomly assigned to one of three treatments: vicarious reinforcement, in which a virtual representation of the physical self (VRS) gained o...

The availability of light in the ocean is an important parameter for the determination of phytoplankton photosynthesis processes and primary production from satellite data. It is also a useful parameter for other applications, e.g. the determination of heat fluxes. In this study, a method was developed utilising the vibrational Raman scattering (VRS) effect of water molecules to determine the n...
