The z = 5.8 Quasar SDSSp J1044−0125: A Peek at Quasar Evolution?
Mathur, Smita ( 2001-10 )The newly discovered z = 5.8 quasar SDSSp J104433.04-012502.2 was recently detected in X-rays and found to be extremely X-ray weak. Here we present the hardness ratio analysis of the XMM-Newton observation. We consider ... -
The Zero Point of Extinction toward Baade's Window from K Giants
Gould, Andrew; Popowski, Piotr; Terndrup, Donald M. ( 1998-01-10 )We measure the zero point of the Stanek extinction map by comparing the observed (V - K) colors of 206 K giant stars with their intrinsic (V - K)_0 colors as derived from their Hβ indices. We find that the zero point of ... -
Zinc in Attention-Deficit/Hyperactivity Disorder
Arnold, L. Eugene; DiSilvestro, Robert A. ( 2005 )Objective: The aim of this study was to review the published evidence for a role of zinc nutrition in attentiondeficit/ hyperactivity disorder (ADHD). Method: A computer literature search was supplemented by the authors’ ... -
The κB transcriptional enhancer motif and signal sequences of V(D)J recombination are targets for the zinc finger protein HIVEP3/KRC: a site selection amplification binding study
Allen, Carl E.; Mak, Chi-ho; Wu, Lai-Chu ( 2002-08-22 )Background: The ZAS family is composed of proteins that regulate transcription via specific gene regulatory elements. The amino-DNA binding domain (ZAS-N) and the carboxyl-DNA binding domain (ZAS-C) of a representative ... -
Ω_B and Ω_0 from MACHOs and Local Group Dynamics
Steigman, G.; Tkachev, I. ( 1999-09-10 )We obtain restrictions on the universal baryon fraction, f_B ≡ Ω_B/Ω_0, by assuming that the observed microlensing events toward the Large Magellanic Cloud are due to baryonic MACHOs in the halo of the Galaxy and by ...
