Kavli Affiliate: Robert Wood | First 5 Authors: Gad Getz, Hilah Gal, Itai Kela, Eytan Domany, Dan A. Notterman | Summary: We present and review Coupled Two Way Clustering, a method designed to mine gene expression data. The method identifies submatrices of the total expression matrix, whose clustering analysis reveals partitions of samples (and genes) […]
Kavli Affiliate: Daniel S. Akerib | First 5 Authors: Daniel S. Akerib, Sean M. Carroll, Marc Kamionkowski, Steven Ritz, | Summary: The past few years have seen dramatic breakthroughs and spectacular and puzzling discoveries in astrophysics and cosmology. In many cases, the new observations can only be explained with the introduction of new fundamental physics. […]
Kavli Affiliate: Yukari Ito | First 5 Authors: Yukari Ito, , , , | Summary: There are many generalizations of the McKay correspondence for higher dimensional Gorenstein quotient singularities and there are some applications to compute the topological invariants today. But some of the invariants are completely different from the classical invariants, in particular for […]
Kavli Affiliate: Claude Canizares | First 5 Authors: David Huenemoerder, Claude Canizares, Kevin Tibbetts, , | Summary: We observed AR Lac, an eclipsing RS CVn binary star, with the Chandra High Energy Grating Spectrometer for a total of 100 ks divided into six intervals covering both quadratures and eclipses. We repeated observations at each phase. […]
Kavli Affiliate: Edmund Bertschinger | First 5 Authors: Hale Bradt, Alan M. Levine, Francis E. Marshall, Ronald A. Remillard, Donald A. Smith | Summary: The role of the Rossi X-ray Timing Explorer (RXTE) in the study of Gamma-ray Bursts (GRBs) is reviewed. Through April 2001, the All-Sky Monitor (ASM) and the Proportional Counter Array (PCA) […]
Kavli Affiliate: Edmund Bertschinger | First 5 Authors: Hale Bradt, Ronald A. Remillard, , , | Summary: A concept for an all-sky monitor mission substantially more powerful than the RXTE ASM is presented in brief. It makes use of 31 Gas Electron Multiplier (GEM) proportional counters to provide continuous monitoring of the entire x-ray sky, […]
Kavli Affiliate: Edmund Bertschinger | First 5 Authors: Hale Bradt, Alan Levine, Ronald Remillard, Donald A. Smith, | Summary: We present a tabulation of 46 transient x-ray sources monitored with the All-Sky Monitor (ASM) on the Rossi X-ray Timing Explorer (RXTE). They fall into four broad categories: short (~d), intermediate, and long (>500 d) duration […]
Kavli Affiliate: George W. Clark | First 5 Authors: Patrick S. Wojdowski, George W. Clark, Timothy R. Kallman, , | Summary: We have investigated the composition and distribution of the wind of Sk 160, the supergiant companion of the X-ray star SMC X-1, by comparing an X-ray spectrum of the source, obtained with the ASCA […]
Kavli Affiliate: Paul McEuen | First 5 Authors: Kent L. McCormick, Michael T. Woodside, Mike Huang, Mingshaw Wu, Paul McEuen | Summary: Using an atomic force microscope as a local voltmeter, we measure the Hall voltage profile in a 2D electron gas in the quantum Hall (QH) regime. We observe a linear profile in the […]
Kavli Affiliate: Shigetaka Moriyama | First 5 Authors: Makoto Minowa, Shigetaka Moriyama, Yoshizumi Inoue, Toshio Namba, Yuko Takasu | Summary: A preliminary result of the solar axion search experiment at the University of Tokyo is presented. We searched for axions which could be produced in the solar core by exploiting the axion helioscope. The helioscope […]
