Early observations of the stellar halos of nearby disk galaxies are discussed. Since most of the currently available data come from deep CCD surface photometry, and it can be diicult to discriminate between spatially overlapping populations with this technique, all non-thin-disk populations (bulges, halos, thick disks, and any component with low surface brightness) are considered. The sample of...

We conducted a genetic analysis of the developing temporo-mandibular or temporomandi-bular joint (TMJ), a highly specialized synovial joint that permits movement and function of the mammalian jaw. First, we used laser capture microdissection to perform a genome-wide expression analysis of each of its developing components. The expression patterns of genes identified in this screen were examined...

Context. The central molecular zone at the Galactic center is currently being studied intensively to understand how star formation proceeds under extreme conditions of a galactic nucleus. Knowing position clouds along line sight toward has had important implications in our understanding physics gas and zone.It was recently claimed that dense cloud G0.253 + 0.016 (the Brick) distance $\sim$7.20 ...

Cool thermal emission components have recently been revealed in the X-ray spectra of a small number of ultraluminous X-ray (ULX) sources with LX ≥ 1040 erg/s in nearby galaxies. These components can be well fitted with accretion disk models, with temperatures approximately 5–10 times lower than disk temperatures measured in stellar-mass Galactic black holes when observed in their brightest stat...

We have obtained high signal-to-noise spectra along the major axes of 28 S0 galaxies in order to search for the presence of disk stars on retrograde orbits. Full line-of-sight velocity distributions were extracted from the data, and the velocity distributions were modelled as arising from the superposition of populations of stars on prograde and retrograde orbits. We find no new cases in which ...

Lumbar disk lesions in 47 cases were initially diagnosed using MRI investigation, then, after surgery, biological and histopathological aspects of intervertebral disks were revealed. Pieces from intervertebral disks were used for electron microscopy studies in order to determine collagen in the components of the intervertebral disk. The aim of the present study was to highlight the corresponden...

In this paper we investigate filesystem support for continuous media on the Java language. We describe a prototype implementation on a Real-Time Java Server developed as an application-level server on the Real-Time Mach microkernel environment. Java virtual machine has been extended to support filesystem bandwidth reservation facilities existing on Real-Time Mach. Such facilities allow continuo...

In virtualized environments, an operating system may not have complete knowledge about its resources, as it sees only virtualized forms of physical resources. The Virtual Machine Monitor which has access to the physical resources, however, is not aware of the abstractions of the operating system. In this paper, we discuss how this lack of information can hinder the implementation of certain mec...

We have obtained J band (1.2 μm) polarimetry observations of the circumbinary disk around UY Aurigae with the University of Hawaii 36 element adaptive optics instrument, Hokupa'a, at the 3.6 m CFHT. The deep (120 min), high resolution (0.15") polarization map reveals a centrosymmetric polarization signature from the light scattered off the circumbinary dust disk which is ~106 times fainter than...

The ability to make intelligent decisions with respect to reducing the energy consumption of mechanical disk drives is dependent upon accurately tracking and accounting the runtime energy consumption of the mechanical and electrical components of the drive in both active and idle states. This work outlines a simple methodology for creating accurate hard drive runtime energy models through the u...
