A key mechanism utilized by plants to make iron (Fe) available for
uptake is the reduction of Fe(III) to Fe(II) via an inducible, plasma
membrane-bound Fe(III) reductase. Genes encoding such enzymes have
not yet been isolated from plants; however, two Fe(III) reductases have
been cloned from yeast. FRE1 and FRE2...
Perspective-taking has been defined as the tendency
to take the point of view of another, to put oneself in
the psychological shoes of another. This ability has
been argued to be an important component of social
interaction. This research examined three components of
perspective-taking: a general measure of perspective
taking...
A comprehensive tribal-level classification for the world's subfamilies of Hesperiidae, the skipper butterflies, is proposed for the first time. Phylogenetic relationships between tribes and subfamilies are inferred using DNA sequence data from three gene regions: 943 bp of cytochrome oxidase subunit I (COI) (in the mitochondrial genome), 739 bp of...
Five Ultra light Fabric Reflux Tubes (UFRTs) were tested in a thermal vacuum chamber at the National Aeronautics and Space Administration's Johnson Space Center in September 1994. These test articles were design and fabricated by staff at the Pacific Northwest Laboratory, operated by Battelle Memorial Institute for the United States...
It is common practice in the unsupervised anomaly detection literature to create experimental benchmarks by sampling from existing supervised learning datasets. We seek to improve this practice by identifying four dimensions important to real-world anomaly detection applications --- point difficulty, clusteredness of anomalies, relevance of features, and relative frequency of...
Existing parallel file systems are proving inadequate in two important arenas:
programmability and performance. Both of these inadequacies can largely be traced
to the fact that nearly all parallel file systems evolved from Unix and rely on a Unix-oriented,
single-stream, block-at-a-time approach to file I/O. This one-size-fits-all
approach to parallel...
The purpose of this study is to illuminate the role,
the function, and the ironic outcome of the Victory in
Vietnam Committee's campaign pamphlet to recall Senator
Frank Church of Idaho in 1967. The VVC's political
strategy was to build credibility with the media through
the recall pamphlet. The analysis...
The importance of accurately identifying inventories of domestic energy, including forest biomass, has increasingly become a priority of the US government and its citizens as the cost of fossil fuels has risen. It is useful to identify which of these resources can be processed and transported at the lowest cost...
