FIG. 1. — Case 1: Brain MRI FLAIR (A) and T2 (B) sequences showing bilateral honeycomb-like pattern involving both capsulo-lenticulostriatal areas and thalami corresponding to dilated VRS. Case 2: Brain MRI T1 (C) and T2 (D) sequences showing left hemispheric fronto-parietal parasagital dilated VRS. Virchow-Robin spaces (VRS) are interstitial fluidfilled pia-lined extensions of the subarachnoid...

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...
