Mallat, Chibli | Federalism in the Middle East and Europe | Federalism is well know in its first, well-established dimension thanks to the extraordinary tradition this country has known. It is less known and is currently a big battle in process in Europe. It is completely unkown and is, I think, the intellectual battle to come in the Middle East. So, these w... | 2003 | |

Ehleringer, James R. | Tracing changes in ecosystem function under elevated carbon dioxide conditions | Responses of ecosystems to elevated levels of atmospheric carbon dioxide (CO2) remain a critical uncertainty in global change research. Two key unknown factors are the fate of carbon newly incorporated by photosynthesis into various pools within the ecosystem and the extent to which elevated CO2 is... | Elevated carbon dioxide; Stable isotopes; Radiocarbon; Global change; Terrestrial ecosystems | 2003 |

Parker, Steven G.; Hansen, Charles D. | Distributed interactive ray tracing for large volume visualization | We have constructed a distributed parallel ray tracing system that interactively produces isosurface renderings from large data sets on a cluster of commodity PCs. The program was derived from the SCI Institute's interactive ray tracer (*-Ray), which utilizes small to large shared memory platforms, ... | Ray tracing; Volume rendering; Large data; Cluster computing; Distributed shared memory | 2003 |

Hansen, Charles D.; Whitaker, Ross T. | Interactive deformation and visualization of level set surfaces using graphics hardware | Deformable isosurfaces, implemented with level-set methods, have demonstrated a great potential in visualization for applications such as segmentation, surface processing, and surface reconstruction. Their usefulness has been limited, however, by their high computational cost and and reliance on sig... | Deformation; Level sets; Deformable models; Image segmentation; Volume visualization; GPU; Streaming computation; Isosurfaces | 2003 |

Zimmer, Zachary | Determinants of old-age mortality in Taiwan | Relationships among socio-demographic characteristics, general assessments of health, and old-age mortality are well established in developed countries. There is also an increasing focus on the connection between early-life experiences and late-life health. This paper tests these and other associat... | Mortality determinants; Gompertz regression | 2003 |

Schmidt, Meic H. | Lumbosacral ependymomas: a review of the management of intradural and extradural tumors | Object. The goal of this study was to review the management of intra- and extradural ependymomas. Spinal ependymomas most commonly occur as intramedullary tumors throughout the spinal axis. In the lumbosacral region, ependymomas are most commonly associated with the conus medullaris and cauda equina... | Intradural ependymoma; Extradural ependymoma; Lumbosacral lesion | 2003 |

Kraus, Peter L. | John Steele Gordon, Thread across the ocean: the historic story of the transatlantic cable | A Thread across the Ocean is a tale of historic and heroic proportions which the author fails to do justice to. The topic is the historic laying of the first telegraph cables across the Atlantic; however, though it is an enjoyable read, it is not a scholarly work. The depth of this work could have ... | 2003 | |

Kieda, David B. | Overview of the ANITA project | The ANITA project is designed to investigate ultra-high energy (>1017 eV) cosmic ray interactions throughout the universe by detecting the neutrinos created in those interactions. These high energy neutrinos are detectable through their interactions within the Antarctic ice sheet, which ANITA will u... | ANITA; Antarctic Impulsive Transient Antenna; High energy neutrinos; Antarctica; Balloon | 2003 |

Zimmer, Zachary | Living arrangements of older adults in sub-Saharan Africa in a time of HIV/AIDS | The detrimental consequences of the AIDS epidemic for older adults in sub-Saharan Africa suggest the need to investigate their characteristics, living situations, and well-being. In this study, we examine the living arrangements of persons aged 60 and older in 16 countries. Data come from the house... | Living arrangements; Older adults; Sub-Saharan Africa; HIV/AIDS | 2003 |

Baehr, Wolfgang | Identification and light-dependent translocation of a cone-specific antigen, (Cone Arrestin) recognized by monoclonal antibody 7G6 | PURPOSE: To elucidate the antigen recognized by monoclonal antibody (mAb) 7G6, a widely used cone-specific marker. METHODS: 7G6 immunocytochemistry was performed on sections of human, primate, and bovine retina. The antigen was immunoprecipitated from human retinal lysates and purified with protein ... | Cones (Retina); Molecular Sequence Data; Phototransduction | 2003 |

Adler, Frederick R. | How virulent should a parasite be to its vector? | Vector-borne parasites are commonly predicted to be less virulent to the vector than to the definitive host as the parasite gains little by harming its main route of transmission. Here we assess the empirical evidence from systems in which insects are vectors for vertebrate, plant, and invertebrate ... | Parasite virulence; Hosts; Vector-borne parasite | 2003 |

Sperry, John S. | Xylem hydraulics and the soil-plant-atmosphere continuum: opportunities and unresolved issues | Received for publication July 23, 2002. Soil and xylem are similar hydraulically. An unsaturated conductivity curve for soil is called a vulnerability curve for xylem?but the underlying physical basis is the same. Thus, any transport model that treats unsaturated soil conductivity would benefit by a... | Soil?plant?atmosphere continuum; Water potential | 2003 |

Landesman, Margaret M. | ATG Interview with Victoria Reich, Director (and founder) of the LOCKSS program | As Vicky and I talked, we discussed her various activities in more or less chronological order. Later on, Vicky said of the work we'd been discussing, "but that's not my true love of the moment." There's not much to say to that, except to ask: ATG: And what is your true love of the moment?

Rogachev, Andrey | Superconducting properties of polycrystalline Nb nanowires templated by carbon nanotubes | Continuous Nb wires, 7-15 nm in diameter, have been fabricated by sputter-coating single fluorinated carbon nanotubes. Transmission electron microscopy revealed that the wires are polycrystalline, having grain sizes of about 5 nm. The critical current of wires thicker than ~12 nm is very high (107 A... | Polycrystalline Nb; Carbon nanotubes; Langer-Ambegaokar-McCumber-Halperin; Phase slips | 2003 |

Tasdizen, Tolga; Whitaker, Ross T. | Feature preserving variational smoothing of terrain data | In this paper, we present a novel two-step, variational and feature preserving smoothing method for terrain data. The first step computes the field of 3D normal vectors from the height map and smoothes them by minimizing a robust penalty function of curvature. This penalty function favors piecewise ... | 2003 | |

Hansen, Charles D.; Johnson, Christopher R. | Constraint-based technique for haptic volume exploration | We present a haptic rendering technique that uses directional constraints to facilitate enhanced exploration modes for volumetric datasets. The algorithm restricts user motion in certain directions by incrementally moving a proxy point along the axes of a local reference frame.
