Faint Blue Objects at High Galactic Latitude. VIII. Performance Characteristics of the US Survey
Autor: Peter D. Usher, K. J. Mitchell
Publikováno v: The Astrophysical Journal Supplement Series. 153:119-157
The US survey has cataloged 3987 objects in seven high Galactic latitude fields according to their optical colors, magnitudes, and morphologies using photographic techniques. This paper analyzes the effectiveness of the survey at producing finding li

The US and Other Optically Selected Bright QSO Samples
Autor: Peter D. Usher, K. J. Mitchell
Publikováno v: International Astronomical Union Colloquium. 184:53-58
The US Bright Quasar Sample (UBQS) is a color-selected sample of quasars with B < 17 that has been constructed with an eye towards completeness within well-defined selection limits. The redshift distribution of the UBQS shows an interesting spike at

The US Survey and the Incidence of Bright Quasars
Autor: K. J. Mitchell, Peter D. Usher
Publikováno v: The Astronomical Journal. 120:1683-1690
The bright quasar sample from the US survey (UBQS) comprises 19 quasars with B 0.3. These subsets and others defined by other morphological criteria currently in use confirm the high incidence of bright US survey quasars previously established with t

14‐YEAR PROGRAM MONITORING THE FLUX DENSITIES OF 33 RADIO SOURCES AT LOW FREQUENCIES
Autor: Daniel R. Altschuler, Brian Dennison, K. J. Mitchell, H. E. Payne, José Francisco Salgado, Tapasi Ghosh
Publikováno v: The Astrophysical Journal Supplement Series. 120:77-93
We present the results of a low-frequency flux density monitoring program of 33 extragalactic radio sources. The light curves at 318 and 430 MHz over a 14 yr period are presented. The measurements were made with the NAIC Arecibo 305 m radio telescope

Autor: Rex A. Saffer, Thomas M. Brown, K. J. Mitchell, Steve B. Howell
Publikováno v: Monthly Notices of the Royal Astronomical Society. 295:225-239
A new sample of 31 faint B and A0 stars is reported, 30 of which comprise a complete sample within the limits (U−V)

UV radiation and temperature affect viability of Serratia spp., potential biocontrol agents of insects
Autor: L. M. Hunt, K. J. Mitchell, J. F. Pearson
Publikováno v: Proceedings of the New Zealand Plant Protection Conference. 50:169-173
Several species within the genus Serratia (Enterobacteriaceae) have potential for use, or are currently used, in the control of insect pests. However, as with most microbes, exposure to certain UV wavelengths can drastically reduce cell viability. In

Source ROCs are (typically) curvilinear: comment on Yonelinas (1999)
Autor: J, Qin, C L, Raye, M K, Johnson, K J, Mitchell
Publikováno v: Journal of experimental psychology. Learning, memory, and cognition. 27(4)
On the basis of his assumption that recollection is a threshold process, A. P. Yonelinas (1999) predicted linear source-identification receiver operating characteristics (ROCs) and recently reported data that were consistent with this prediction. In

Aging and reflective processes of working memory: binding and test load deficits
Autor: K J, Mitchell, M K, Johnson, C L, Raye, M, Mather, M, D'Esposito
Publikováno v: Psychology and aging. 15(3)
It was hypothesized that age-related deficits in episodic memory for feature combinations (e.g., B. L. ChalfonteM. K. Johnson, 1996) signal, in part, decrements in the efficacy of reflective component processes (e.g., M. K. Johnson, 1992) that suppor
