Chandran, Ravi | Evolution of microstructure and phases in in-situ processed Ti-TiB composites containing high volume fractions of TiB whiskers | A series of titanium composites, with varying volume fractions of titanium monoboride (TiB) whiskers, were made by mixing various proportions of titanium (Ti) and titanium diboride (TiB2) powders followed by hot pressing. The phases present were identified by x-ray diffraction. | Morphology; diffraction; relative intensity | 1999 |

Brown, Francis Harold | The evolution of neogene terrestrial ecosystems in Europe | The Pliocene-Pleistocene chronology of hominid and other vertebrate evolution in East Africa is largely constrained by isotopic dating and regional intercorrelation of volcanic ash layers.

Jones, Bryan W.; Jones, Christopher R.; Czajkowski, Laura | Familial advanced sleep-phase syndrome: a short-period circadian rhythmvariant in humans | Biological circadian clocks oscillate with an approximately 24-hour period, are ubiquitous, and presumably confer a selective advantage by anticipating the transitions between day and night.

Clayton, Dale H. | Feather-busting bacteria | I ONCE HAD A COLLEAGUE who delighted in the aphorism, which he proudly coined himself, "If it's too small to see with the naked eye, it ain't there." Sadly, this view may as well be true for ornithologists who study birds only through unaided eyes, binoculars, or spotting scopes. But birds can also ... | Columba livia; Columbiformes; Ectoparasites; Bacteria; Plumage | 1999 |

Zhdanov, Michael S. | Focusing geophysical inversion images | A critical problem in inversion of geophysical data is developing a stable inverse problem solution that can simultaneously resolve complicated geological structures.

Zhang, Chengqiang | Hardware-only stream prediction + cache prefetching + dynamic access ordering | The speed gap between processors and memory system is becoming the performance bottleneck for many applications, and computations with strided access patterns are among those that suffer most. The vectors used in such applications lack temporal and often spatial locality, and are usually too large t... | Speed gap; Stream prediction; Cache prefetching; Dynamic access ordering | 1999 |

Breaderson, Dean J. | The I3Stick: an inexpensive, immersive, interaction device | Virtual environments require interaction devices that are intuitive and ergonomic, yet capable of many input parameters. Many devices satisfying these requirements can be expensive, difficult to manipulate, and often require the integration of large software libraries with existing applications. We ... | Virtual environments; I3Stick; Interaction devices | 1999 |

Baehr, Wolfgang; Thulin, Craig | Immunolocalization and divergent roles of phosducin and phosducin-like protein in the retina | PURPOSE: These investigations were undertaken to compare and contrast the roles of phosducin and phosducin-like protein in the retina. METHODS: Phosducin and phosducin-like protein were compared in an in vitro assay measuring their inhibition of transducin binding to light-activated rhodopsin.

Gondolo, Paolo | Indirect detection of dark matter in km-size neutrino telescopes | Neutrino telescopes of kilometer size are currently being planned. They will be two or three orders of magnitude larger than presently operating detectors, but they will have a much higher muon energy threshold.

Riloff, Ellen M. | Information extraction as a stepping stone toward story understanding | Historically story understanding systems have depended on a great deal of handcrafted knowledge. Natural language understanding systems that use conceptual knowledge structures (Schank and Abelson 1977; Cullingford 1978; Wilensky 1978; Carbonell 1979; Lehnert 1981; Kolodner 1983) typically rely on ... | Information extraction; Story understanding | 1999 |

Johnson, Christopher R.; Parker, Steven G.; Hansen, Charles D. | Interactive simulation and visualization | Most of us perform data analysis and visualization only after everything else is finished, which often means that we don't discover errors invalidating the results of our simulation until postprocessing.
