Protein Science, 2009 AbstractMany protein classification systems capture homologous relationships by grouping domains into families and superfamilies on the basis of sequence similarity. Superfamilies with similar 3D structures are further grouped into folds. In the absence of discernable sequence similarity, these structural similarities were long thought to have ...

Silicosarcoidosis: Histologic and Clinical Features of an Occupational Granulomatous Disease
American Journal of Industrial Medicine, EarlyView.ABSTRACT Sarcoidosis is a multisystem inflammatory disease of unknown etiology. Growing evidence indicates that occupational exposure to respirable crystalline silica (RCS) is associated with an increased incidence of sarcoidosis. Yet a diagnosis of sarcoidosis rarely prompts investigation to identify preventable exposures.

Active Dwarf Galaxies as Circumnuclear Regions of LSB-galaxies [PDF]
arXiv, 2006 Some arguments are brought that often active dwarf galaxies are the circumnuclear regions of LSB-galaxies in fact,rather than an ordinary galaxies.
arxiv
The Astronomical Journal, 2012 A growing number of low luminosity and low surface brightness astronomical objects challenge traditional notions of both galaxies and star clusters. To address this, we propose a definition of galaxy independent of the cold dark matter model of the universe: A galaxy is a gravitationally bound set of stars whose properties cannot be explained by a ...

Journal of the Association for Information Science and Technology, EarlyView.Abstract Provenance is the story of how something has come to be. In this paper, we provide a systematic literature review to categorize the various notions of provenance in Information Sciences. The goal of this review is to paint a broader picture of the multiple uses of provenance at play and to enhance our understanding of the importance of ...

Formation of a polar-ring galaxy in a galaxy merger [PDF]
, 1998 We numerically investigate stellar and gas dynamics in star-forming and dissipative galaxy mergers between two disk galaxies with specific orbital configurations. We find that violent relaxation combined with gaseous dissipation in galaxy merging transforms two disk galaxies into one S0 galaxy with polar-rings: Both the central S0-like host and the ...

Galaxy harassment and the evolution of clusters of galaxies [PDF]
Nature, 1996 Disturbed spiral galaxies with high rates of star formation pervaded clusters of galaxies just a few billion years ago, but nearby clusters exclude spirals in favor of ellipticals. ``Galaxy harassment" (frequent high speed galaxy encounters) drives the morphological transformation of galaxies in clusters, provides fuel for quasars in subluminous hosts ...

Discovery of a Nearby Low-Surface-Brightness Spiral Galaxy [PDF]
, 1998 During the course of a search for compact, isolated gas clouds moving with anomalous velocities in or near our own Galaxy (Braun and Burton 1998 A&A, in press), we have discovered, in the data of the Leiden/Dwingeloo survey (Hartmann and Burton 1997 ...

Astronomische Nachrichten, EarlyView.ABSTRACT Classification of galaxies, stars, and quasars using spectral data is fundamental to astronomy, but often relies heavily on redshift. This study evaluates the performance of 10 machine learning algorithms on SDSS data to classify these objects, with a particular focus on scenarios where redshift information is unavailable.
