Veranth, John M. | Computational modeling of CO/CO2 ratio inside single char particles during pulverized coal combustion | A recently developed model was used to study the CO/CO2 ratio inside a burning pulverized coal particle, to better understand the effect of bulk gas composition on the equilibrium partial pressure of reduced metal species at the surface of ash inclusions. The motivation was to improve the ability to... | Pulverized coal combustion; Computational modeling; Char | 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. Reaction forces are g... | Haptic rendering; Immersive visualization; Human-computer interaction | 2003 |

Goller, Franz | Coordination and synergism between visual and vocal display in the brown-headed cowbirds | Sexually selected acoustic signaling is accompanied by visual displays in many birds. The motor integration of visual and vocal displays has not been extensively studied. Brown-headed cowbirds (Molothrus ater) "puff up" prior to song, move their wings during the song and conclude with a bow. The ... | Acoustic signaling; Wing display; Synergistic interaction | 2003 |

Zhdanov, Michael | Cross-well electromagnetic imaging in three dimensions | In this paper, we develop a new technique for 3D cross-well electromagnetic tomography, based on an EM borehole survey consisting of a moving vertical magnetic dipole transmitter, located in one or several boreholes, and a tri-axial induction receiver, located in the other boreholes. The method is b... | 2003 | |

Tasdizen, Tolga; Whitaker, Ross T. | Curvature-based transfer functions for direct volume rendering: methods and applications | Direct volume rendering of scalar fields uses a transfer function to map locally measured data properties to opacities and colors. The domain of the transfer function is typically the one-dimensional space of scalar data values. This paper advances the use of curvature information in multi-dimensio... | 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 |

Reichler, Thomas J. | Determining the tropopause height from gridded data | A method is presented to determine tropopause height from gridded temperature data with coarse vertical resolution. The algorithm uses a thermal definition of the tropopause, which is based on the concept of a threshold lapse-rate. Interpolation is performed to identify the pressure at which this th... | Meteorology and Atmospheric Dynamics: Stratosphere/troposphere interactions; Numerical modeling and data assimilation; Meteorology; Atmospheric Dynamics: General circulation | 2003 |

Schmidt, Meic H. | Diagnosis and management of sacral Tarlov cysts | Perineurial (Tarlov) cysts are meningeal dilations of the posterior spinal nerve root sheath that most often affect sacral roots and can cause a progressive painful radiculopathy. Tarlov cysts are most commonly diagnosed by lumbosacral magnetic resonance imaging and can often be demonstrated by com... | Tarlov cysts; Meningeal dilations; Spinal lesion; Outcome | 2003 |

Schmidt, Meic H. | Diffuse large B-cell lymphoma presenting as a sacral tumor | Primary lymphomas of the sacrum are rare tumors, reported only in a few cases in the literature. The authors describe two patients with diffuse large B-cell lymphomas presenting as a sacral tumor. In the first case a 52-year-old man presented with progressive back pain, bilateral radicular pain, an... | B-cell lymphoma; Sacral tumor | 2003 |

Morse, Michael David | Dispersed fluorsecence spectroscopy of AINi, NiAu, and PtCu | Dispersed fluorescence studies of AlNi, NiAu, and PtCu have been performed, providing spectroscopic information about the ground and low-lying excited electronic states. Vibrational frequencies are reported for the ground X 2?5/2 state of all three molecules. In the case of AlNi, fluorescence to all... | 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 |

Millgram, Elijah | Does the categorical imperative give rise to a contradiction in the will? | The Brave New World-style utilitarian dystopia is a familiar feature of the cultural landscape; Kantian dystopias are harder to come by, perhaps because, until Rawls, Kantian morality presented itself as a primarily personal rather than political program. This asymmetry is peculiar for formal reas... | Categorical imperative; Dystopia; Self-refutation | 2003 |

Jameson, Kenneth P. | Dollarization in Latin America: wave of the future or flight to the past? | Ecuador undertook official dollarization in 2000 when it destroyed its own currency, the sucre, and adopted the dollar. El Salvador converted all financial instruments to dollars, and Guatemala now allows transactions to be carried out in any currency. Both assumed that the dollar would soon displac... | Domestic currencies; Latin America; Dollarization | 2003 |

Goldberg, Robert A. | Don't know much about history | Most of us have heard of the "Greatest Generation," those who weathered the storms of the Great Depression and World War II. Many of us are Baby Boomers, born between 1946 and 1965. Other are part of the cynical and worldly Generation X-arriving between the mid '60s and the early '80s-raised in the ... | 2003 | |

Smith, Ken R. | Double impact: what sibling data can tell us about the long-term negative effects of parental divorce | Most prior research on the adverse consequences of parental divorce has analyzed only one child per family. As a result, it is not known whether the same divorce affects siblings differently. We address this issue by analyzing paired sibling data from the 1994 General Social Survey (GSS) and 1994 Su... | Divorce; Siblings; Educational attainment; Marital stability | 2003 |

Couldwell, William T.; Orlandi, Richard R.; Jensen, Randy L. | Endoscopic-assisted craniofacial resection of esthesioneuroblastoma: minimizing facial incisions | The surgical management of esthesioneuroblastomas has traditionally been craniofacial resection, which combines a bifrontal craniotomy with a transfacial approach. The latter usually involves a disfiguring facial incision, mid-facial degloving, lateral rhinotomy, and/or extensive facial osteotomies... | Esthesioneuroblastoma; Craniofacial resection; Endoscope; Craniofacial surgery; Minimally invasive | 2003 |
