Distances and Metallicities of HVCS
2004We review the methods for determining the distances and metallicities of high-velocity clouds. A short summary is given of several indirect methods, but we concentrate on the absorption-line method, which is based on the detection and non-detection of interstellar absorption lines in the spectra of background and foreground stars, as well as of ...

HVCS Interacting With Their Environment
2004We present observational evidence and review theoretical considerations for an interaction of high-velocity clouds (HVCs) with their ambient medium. HVCs showing either a head-tail structure or a horseshoe shape are likely to be interacting. Such HVCs are observed in complexes in the gaseous Galactic Halo (e.g. complex A), in HVC complexes in the outer

Repertoire sharing and auditory responses in the HVC of the canary
NeuroReport, 2009In songbirds, auditory neurons of the nucleus HVC respond selectively to a particular complex sound, the bird's own song (BOS). In the canary, this song selectivity did not exclude responses to conspecific songs. Here, we recorded single units in nucleus HVC of adult canaries to assess to what extent repertoire sharing among birds contributed to ...

Medical Image Enhancement Based on HVC
2007 1st International Conference on Bioinformatics and Biomedical Engineering, 2007Medical image enhancement is to process the image so that the result is more suitable than the original image for analysis and diagnosis. The information of image is acquired by the observer's eyes, so in the image processing, the human visual characteristics (HVC) as an important factor should be well thought of.

HVC/IVC Maps and HVC Distribution Functions
2004This chapter presents an overview of the basic sky, velocity, column density, volume density, area, and flux distributions of the high-velocity clouds (HVCs). All-sky maps are shown of their deviation and GSR velocities, and their column densities.

Are Highly-Ionized HVCs a Galactic Phenomenon?
AIP Conference Proceedings, 2009Highly‐ionized high‐velocity clouds have been studied for the last decade. Some lines of reasoning have suggested an extragalactic origin for these clouds, placing them near the outskirts of the Milky Way or Local Group, and some models have explored the possibility that they may be associated with dark matter minihalos. We have observed highly‐ionized

HVCS Related to the Magellanic System
2004This chapter provides a review of the observational and theoretical results on the HVCs known to have originated from the interaction of the Large and Small Magellanic Clouds with each other and the Milky Way. The neutral hydrogen observations of the Magellanic Bridge, Magellanic Stream, and Leading Arm are summarized and related to the optical and ...

The Large- and Small-scale Structure of HVCs
2004The main question addressed in this chapter is whether or not HVCs have small-scale structure that di ers from that in low-velocity gas and the IVCs. If so, this could make it possible to distinguish HVCs from galactic gas not only by their deviating velocities, but also by their structural characteristics. Further, the physical characteristics derived

HVC interneurons are not renewed in adult male zebra finches
European Journal of Neuroscience, 2007AbstractAdult neurogenesis is a widespread phenomenon in many species, from invertebrates to humans. In songbirds, the telencephalic region, high vocal center (HVC), continuously integrates new neurons in adulthood. This nucleus consists of a heterogenous population of inhibitory interneurons (HVCIN) and two populations of projection neurons that send ...

HVC: A Hybrid Cloud Computing Framework in Vehicular Environments
2017 5th IEEE International Conference on Mobile Cloud Computing, Services, and Engineering (MobileCloud), 2017As increasingly more applications are deployed in vehicles, how to provide the demanded computational capability becomes crucial. This paper proposes the hybrid vehicular cloud (HVC) framework for cloud computing on the road to increase the computational capability of vehicles by using resources from the centralized cloud, RSU, and neighboring vehicles.
