Filtrated K-theory for real rank zero C*-algebras
Sara Arklint, Gunnar Restorff, Efren Ruiz
Using Kirchberg KK_X-classification of purely infinite, separable, stable, nuclear C*-algebras with finite primitive ideal space, Bentmann showed that filtrated K-theory classifies…
Information Security Synthesis in Online Universities
Maria Schuett, Syed, M. Rahman
Information assurance is at the core of every initiative that an organization executes. For online universities, a common and complex initiative is maintaining user lifecycle and p…
Architecture and Design of Medical Processor Units for Medical Networks
Syed V. Ahamed, Syed Shawon M. Rahman
This paper introduces analogical and deductive methodologies for the design medical processor units (MPUs). From the study of evolution of numerous earlier processors, we derive th…
Amplified graph C*-algebras
Søren Eilers, Efren Ruiz, Adam P. W. Sørensen
We provide a complete invariant for graph C*-algebras which are amplified in the sense that whenever there is an edge between two vertices, there are infinitely many. The invariant…
Images of the Extended Outer Regions of the Debris Ring Around HR 4796 A
C. Thalmann, M. Janson, E. Buenzli +48
We present high-contrast images of HR 4796 A taken with Subaru/HiCIAO in H-band, resolving the debris disk in scattered light. The application of specialized angular differential i…
Eruptive Variable Stars and Outflows in Serpens NW
Klaus W. Hodapp, Rolf Chini, Ramon Watermann +1
We study the outflow activity, photometric variability and morphology of three very young stellar objects in the Serpens NW star forming region: OO Serpentis, EC 37 (V370 Ser) and…
A luminous quasar at a redshift of z = 7.085
Daniel J. Mortlock, Stephen J. Warren, Bram P. Venemans +14
The intergalactic medium was not completely reionized until approximately a billion years after the Big Bang, as revealed by observations of quasars with redshifts of less than 6.5…
Observational Search for PeV-EeV Tau Neutrino from GRB081203A
Y. Aita, T. Aoki, Y. Asaoka +16
We report the first observational search for tau neutrinos from gamma ray bursts (GRBs) using one of the Ashra light collectors. The earth-skimming tau-neutrino technique of imagin…
Young Exoplanet Transit Initiative (YETI)
R. Neuhäuser, R. Errmann, A. Berndt +80
We present the Young Exoplanet Transit Initiative (YETI), in which we use several 0.2 to 2.6m telescopes around the world to monitor continuously young (< 100 Myr), nearby (< 1 kpc…
The ordered K-theory of a full extension
Søren Eilers, Gunnar Restorff, Efren Ruiz
Let A be a C*-algebra with real rank zero which has the stable weak cancellation property. Let I be an ideal of A such that I is stable and satisfies the corona factorization prope…
Determination of stellar parameters of C-rich hydrostatic stars from spectro-interferometric observations
C. Paladini, G. T. van Belle, B. Aringer +4
Giant stars, and especially C-rich giants, contribute significantly to the chemical enrichment of galaxies. The determination of precise parameters for these stars is a necessary p…
Episodic mass loss in binary evolution to the Wolf-Rayet phase: Keck and HST proper motions of RY Scuti's nebula
Nathan Smith, Robert D. Gehrz, Randy Campbell +4
Binary mass transfer via Roche-lobe overflow (RLOF) is a key channel for producing stripped-envelope Wolf-Rayet (WR) stars and may be critical to account for SN Ib/c progenitors. R…
An extremely luminous panchromatic outburst from the nucleus of a distant galaxy
A. J. Levan, N. R. Tanvir, S. B. Cenko +58
Variable X-ray and gamma-ray emission is characteristic of the most extreme physical processes in the Universe, and studying the sources of these energetic photons has been a major…
Discovery of carbon monoxide in the upper atmosphere of Pluto
J. S. Greaves, Ch. Helling, P. Friberg
Pluto's icy surface has changed colour and its atmosphere has swelled since its last closest approach to the Sun in 1989. The thin atmosphere is produced by evaporating ices, and s…
YSOVAR: the first sensitive, wide-area, mid-IR photometric monitoring of the ONC
M. Morales-Calderón, J. R. Stauffer, L. A. Hillenbrand +33
We present initial results from time series imaging at infrared wavelengths of 0.9 sq. degrees in the Orion Nebula Cluster (ONC). During Fall 2009 we obtained 81 epochs of Spitzer…
First results from the MIT Optical Rapid Imaging System (MORIS) on the IRTF: a stellar occultation by Pluto and a transit by exoplanet XO-2b
A. A. S. Gulbis, S. J. Bus, J. L. Elliot +8
We present a high-speed, visible-wavelength imaging instrument: MORIS (the MIT Optical Rapid Imaging System). MORIS is mounted on the 3-m Infrared Telescope Facility (IRTF) on Maun…
Direct Imaging of Fine Structures in Giant Planet Forming Regions of the Protoplanetary Disk around AB Aurigae
J. Hashimoto, M. Tamura, T. Muto +49
We report high-resolution 1.6 $\micron$ polarized intensity () images of the circumstellar disk around the Herbig Ae star AB Aur at a radial distance of 22 AU () up to 5…
A spectral comparison of (379) Huenna and its satellite
Francesca DeMeo, Benoit Carry, Franck Marchis +7
We present near-infrared spectral measurements of Themis family asteroid (379) Huenna (D~98 km) and its 6 km satellite using SpeX on the NASA IRTF. The companion was farther than 1…
An Overview of the Security Concerns in Enterprise Cloud Computing
Anthony Bisong, Syed, M. Rahman
Deploying cloud computing in an enterprise infrastructure bring significant security concerns. Successful implementation of cloud computing in an enterprise requires proper plannin…
The Globular Cluster Systems of Abell 1185
Michael J. West, Andres Jordan, John P. Blakeslee +4
We examine the properties of a previously discovered population of globular clusters in the heart of the rich galaxy cluster Abell 1185 that might be intergalactic in nature. Deep…
A parsec-scale outflow from the luminous YSO IRAS 17527-2439
Watson P. Varricatt
Imaging observations of IRAS 17527-2439 are obtained in the near-IR JHK photometric bands and in a narrow-band filter centred at the wavelength of the H_2 1-0 S(1) line. The contin…
