Normann, Richard A. | Background and bleaching adaptation in luminosity type horizontal cells in the isolated turtle retina | 1. The effects of background illumination and bleached photopigment on luminosity type horizontal cells were studied in the isolated turtle retina. 2. Background illumination, which produced less than 60% bleaching, hyperpolarized and desensitized the horizontal cells to a degree which depended upon... | Turtles; Retina; Photoreceptors; Bleached photopigment; Dark Adaptation | 1990 |

Jarrard, Richard D. | Electrical properties of basalts from Sites 768 and 770 | Conductivity of 54 basalt samples from ODP Sites 768 and 770 was measured as a function of temperature and fluid salinity. Porosity was also measured for all samples, and cation exchange capacity was measured for 46 of the samples. Porosity measurements indicated that porosity is underestimated fo... | 1991 | |

Balasubramonian, Rajeev | Microarchitectural wire management for performance and power in partitioned architectures | Future high-performance billion-transistor processors are likely to employ partitioned architectures to achieve high clock speeds, high parallelism, low design complexity, and low power. In such architectures, inter-partition communication over global wires has a significant impact on overall proc... | Microarchitecture; Partitioned architectures; Heterogeneous interconnects; Cache access | 2005 |

Gerig, Guido | Multi-object analysis of volume, pose, and shape using statistical discrimination | One goal of statistical shape analysis is the discrimination between two populations of objects. Whereas traditional shape analysis was mostly concerned with single objects, analysis of multi-object complexes presents new challenges related to alignment and pose. In this paper, we present a methodol... | 2010-01-01 | |

Vardeny, Zeev Valentine | Photophysics of pristine and C60-doped disubstituted polyacetylene | Using a variety of steady-state spectroscopies we studied the long-lived photoexcitations and electronic excited states of poly disubstituted acetylene (PDPA-nBu), the backbone structure of which is a disubstituted trans-polyacetylene, as well as PDPA-nBu/C60 blends. The cw spectroscopies include a... | Photophysics; Pristine disubstituted polyacetylene; C60-doped disubstituted polyacetylene; pi-conjugated polymers; Photoexcitations; Electronic excited states | 2002-08 |

Goller, Franz | Prosthetic Avian vocal organ controlled by a freely behaving bird based on a low dimensional model of the biomechanical periphery | Because of the parallels found with human language production and acquisition, birdsong is an ideal animal model to study general mechanisms underlying complex, learned motor behavior. The rich and diverse vocalizations of songbirds emerge as a result of the interaction between a pattern generator i... | 2012-01-01 | |

Jewell, Paul | Controls of tufa development in Pleistocene Lake Bonneville, Utah | Prominent tufa localities along the Provo level (∼14,000 14C yr B.P.) shoreline in Pleistocene Lake Bonneville have been characterized in detail. Three types of tufa are recognized: capping tufa, beachrock, and capping tufa over beachrock. Capping tufa and beachrock are end members of a continuum ... | Tufa; Pleistocene; Pluvial lakes | 2006 |

Rogers, Alan R.; Jorde, Lynn B. | Genetic structure of the Utah Mormons: comparison of results based on RFLPs, blood groups, migration matrices, isonymy, and pedigrees | The genetic structure of the Utah Mormon population is examined using 25 blood group and 47 RFLP alleles obtained from 442 subjects living in 8 geographic subdivisions. Nei's Gst was 0.013 (p < 0.002) for the RFLP data and 0.012 (p > 0.4) for the blood group data, showing that only 1% of the geneti... | 1994 | |

Hawkes, Kristen | Hadza scavenging: implications for Plio/Pleistocene Hominid subsistence | The frequent association of stone tools and large animal bones in African Plio/Pleistocene archaeological sites has long been taken as evidence of the importance of hunting in early hominid diets. Many now argue that it reflects hominid scavenging, not hunting. | Hadza; Scavenging; Plio/Pleistocene; Hominid Diet | 1988-04 |

Bernstein, Paul S. | Human retinal pigment epithelial cell line that retains epithelial characteristics after prolonged culture | PURPOSE. A spontaneously arising, apparently transformed, cell line has been cloned from a primary culture of human retinal pigment epithelial (RPE) cells and has been subcultured more than 200 times. The similarities of these cells to human RPE cells in vivo have been determined. METHODS. The struc... | Cell Line, Transformed; Chromatography, High Pressure Liquid; Phagocytosis | 1995 |
