 | Capecchi, Mario R. | Role of the N-terminal catalytic domain of angiotensin-converting enzyme investigated by targeted inactivation in mice | Angiotensin-converting enzyme (ACE) produces the vasoconstrictor angiotensin II. The ACE protein is composed of two homologous domains, each binding zinc and each independently catalytic. To assess the physiologic significance of the two ACE catalytic domains, we used gene targeting in mice to int... | 2004-02-13 | |

 | Aldous, Wade K.; Hymas, Weston C.; Stevenson, Jeffery B.; Taggart, Edward W.;Hillyard, David R. | Single tube real-time RT-PCR Assay for the detection of enterovirus | We developed a rapid and sensitive method for the routine detection of enterovirus in CSF and plasma using a one tube, one step, real-time PCR assay. A primer set and an Eclipse probe were designed to target the highly conserved 5' untranslated region of the enterovirus genome. This assay was compar... | MGB Eclipse; Viral RNA; Picornaviridae | 2004-09-11 |

 | Harrison, Reid R. | Single-chip CMOS visual orientation sensor | We present a single-chip, low-power vision sensor capable of measuring local edge orientation across a wide field of view. The sensor was fabricated in a 0.5-µm CMOS process. Quadratic spatial filters were implemented using differential pairs and an "antibump" circuit to give a current-mode out... | Low-power; Vision sensor; CMOS | 2004-01-01 |

 | Freire, Juliana | Siphoning hidden-web data through keyword-based interfaces | In this paper, we study the problem of automating the retrieval of data hidden behind simple search interfaces that accept keyword-based queries. Our goal is to automatically retrieve all available results (or, as many as possible). We propose a new approach to siphon hidden data that automatically ... | 2004-01-01 | |

 | Beck, Susan L. | Symptom clusters: impediments and suggestions for solutions. | The human experience of cancer is marked by the occurrence of multiple symptoms that influence one's ability to continue usual activities and enjoy life. Although the symptom experience is complex and multifaceted, knowledge of it has been limited by a paradigm that has been singular in scope... | Cancer; Symptoms; Symptom Management; End-of-Life Care; Depression | 2004-07-21 |

 | Simpson, Jamesina J. | Three-dimensional FDTD modeling of impulsive ELF propagation about the earth-sphere | This paper reports the application of an efficient finite-difference time-domain (FDTD) algorithm to model impulsive extremely low frequency (ELF) propagation within the entire Earth-ionosphere cavity. Periodic boundary conditions are used in conjunction with a three-dimensional latitude-longitude F... | 2004-01-01 | |

 | Gerig, Guido | Unbiased diffeomorphic atlas construction for computational anatomy | Construction of population atlases is a key issue in medical image analysis, and particularly in brain mapping. Large sets of images are mapped into a common coordinate system to study intra-population variability and inter-population differences, to provide voxel-wise mapping of functional sites, a... | 2004-01-01 | |

 | Harrison, Reid R. | Validation of adaptive threshold spike detector for neural recording | We compare the performance of algorithms for automatic spike detection in neural recording applications. Each algorithm sets a threshold based on an estimate of the background noise level. The adaptive spike detection algorithm is suitable for implementation in analog VLSI; results from a proof-of-... | Spike detection; Neural recording; Ation potential; VLSI | 2004-01-01 |

 | Kindlmann, Gordon | Visualization and analysis of diffusion tensor fields | The power of medical imaging modalities to measure and characterize biological tissue is amplified by visualization and analysis methods that help researchers to see and understand the structures within their data. Diffusion tensor magnetic resonance imaging can measure microstructural properties... | diffusion tensor fields; Visualization; medical imaging | 2004-09-28 |

 | Welfare state expenditures and the redistribution of well-being: children, elders, and others in comparative perspective | This paper estimates the redistributive effects of welfare state expenditures on social and economic disparities in the economic well-being of citizens in ten nations. Data from the Organization for Economic Cooperation and Development (OECD) and other sources for cash and non-cash social welfare... | Social programs; Social work; Low-income; Public assistance | 2004-10-19 | |

 | Harrison, Reid R.; Tabib-Azar, Massood | Wireless multi-channel sensor for neurodynamic studies | This paper presents the design of a bio-compatible, implantable neural recording device for Aplysia californica, a common sea slug. Low-voltage extracellular neural signals (<100 μV) are recorded using a high-performance, low-power, low-noise preamplifier that is integrated with programmable data a... | Implantable; Data acquisition; Neural recording; Neural signals; Telemetry; Low-power circuits; Low-noise amplifier; Sea slug | 2004-01-01 |
