the theoretical base of this paper is the economic growth model that completed with capital stocks (private and public) and human capital. at the first, hypothesis test about constant returns to scale is studied, and then the related variables with macroeconomic policies are added to the model. the results show that 1) the aggregate production function exhibits increasing returns to scale, 2) p...

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...

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...

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 ...

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 ...

In the past few years, network RTK positioning technology, especially the VRS ( virtual reference stations)technology, has been widely used in some parts of China and many countries of the world. In this paper, the authors mainly discuss the principle of VRS technology with corresponding formula deduction, and give detailed descriptions of VRS corrections and virtual observations generation alg...
