Parker, Bradley J. | Archaeological manifestations of empire: Assyrias imprint on Southeastern Anatolia | One of the most enduring problems for the study of ancient empires is the fact that material correlates indicative of imperial integration are often difficult to define in the archaeological record. This situation results in part from two factors that distinguish empires from other less complex poli... | 2003-01-01 | |

Couldwell, William T. | Assessment of long-term remission of acromegaly following surgery | Object. The criteria for remission of acromegaly following transsphenoidal adenoma resection are in evolution. In the present study the authors evaluate the utility of predicting long-term remission by reference to a single fasting growth hormone (GH) level on the 1st postoperative day. Methods.

Gerig, Guido | Automatic and robust computation of 3D medial models incorporating object variability | Abstract. This paper presents a novel processing scheme for the automatic and robust computation of a medial shape model which represents an object population with shape variability. The sensitivity of medial descriptions to object variations and small boundary perturbations are fundamental problems... | 2003-01-01 | |

Sekercioglu, Cagan | Birding economics: conservation through commodification | In the long-run, the quality of our birding (and the length of our lists) depends on our success in conserving birds and their habitats. Who would not love to see a Labrador Duck during a pelagic trip, have Carolina Parakeets fly overhead on a CBC, or photograph a Bachman's Warbler foraging in a can... | 2003-01-01 | |

Poulter, Charles Dale | Catalytic mechanism of Escherichia coli isopentenyl diphosphate isomerase involves Cys-67, Glu-116, and Tyr-104 as suggested by crystal structures of complexes with transition state analogues and irreversible inhibitors | Isopentenyl diphosphate (IPP):dimethylallyl diphosphate (DMAPP) isomerase is a key enzyme in the biosynthesis of isoprenoids. The reaction involves protonation and deprotonation of the isoprenoid unit and proceeds through a carbocationic transition state. Analysis of the crystal structures (2 A) of ... | Catalytic Domain; Crystallography; Organophosphorus Compounds | 2003-04-04 |

Kniss, Joe; Ikits, Milan; Lefohn, Aaron; Hansen, Charles D. | Closed-form approximations to the volume rendering integral with Gaussian transfer functions | In direct volume rendering, transfer functions map data points to optical properties such as color and opacity. We have found transfer functions based on the Gaussian primitive to be particularly useful for multivariate volumes, because they are simple and rely on a limited number of free paramet... | Volume rendering | 2003-07-25 |

Couldwell, William T. | Communication between malignant glioma cells and vascular endothelial cells through gap junctions | Object. Extensive invasion and angiogenesis are hallmark features of malignant gliomas. Communication between malignant glioma cells and surrounding astrocytes occurs, resulting in transformation of the astrocytic phenotype. In the present study, the authors examined whether malignant glioma cells a... | 2003-01-01 | |

Susarla, Sai R.; Carter, John | Composable consistency for large-scale peer replication | The lack of a flexible consistency management solution hinders P2P implementation of applications involving updates, such as directory services, online auctions and collaboration. Managing shared data in a P2P setting requires a consistency solution that can operate in a heterogenous network, sup... | P2P | 2003-11-14 |

Tasdizen, Tolga; Whitaker, Ross T. | Cramer-Rao bounds for nonparametric surface reconstruction from range data | The Cramer-Rao error bound provides a fundamental limit on the expected performance of a statistical estimator. The error bound depends on the general properties of the system, but not on the specific properties of the estimator or the solution. The Cramer-Rao error bound has been applied to scal... | Cramer-Rao bounds; Error bounds; 3D reconstruction | 2003-04-18 |

Harrison, Reid R. | Custom multielectrode array with integrated low-noise preamplifiers | Multielectrode arrays (MEAs) have emerged as a leading technology for extracellular neural recording and stimulation. Their large number of recording sites promises to yield important insight into neural systems. As the density of recording sites increases, interfacing to each electrode becomes inc... | Electrode; Multielectrode arrays (MEA); Neural recording; Extracellular recording; Low-noise | 2003-01-01 |

Susarla, Sai R.; Carter, John | DataStations: ubiquitous transient storage for mobile users | In this paper, we describe DataStations, an architecture that provides ubiquitous transient storage to arbitrary mobile applications. Mobile users can utilize a nearby DataStation as a proxy cache for their remote home file servers, as a file server to meet transient storage needs, and as a platf... | DataStations; Ubiquitous transient storage; Proxy cache | 2003-11-14 |

Florsheim, Paul W.; Ngu, Le | Differential outcomes among adolescent fathers: understanding fatherhood as a transformative process | In response to the rising numbers of mother headed households, there is a great debate about whether to encourage young unwed parents to marry. Policies designed to pursue and/or punish fathers who do not meet their legal and financial responsibilities and to promote marriage, carte blanche, are ref... | Parenting; Gender; Matrimony | 2003-10-18 |

Poulter, Charles Dale | Enzymes encoded by the farnesyl diphosphate synthase gene family in the big sagebrush Artemisia tridentata ssp. spiciformis | Farnesyl diphosphate synthase catalyzes the sequential head-to-tail condensation of two molecules of isopentenyl diphosphate with dimethylallyl diphosphate. In plants the presence of farnesyl diphosphate synthase isozymes offers the possibility of differential regulation.

Family structure and adolescent labor market participation: examining the motives for and effects of at-risk students' work for pay during high school | In this paper, I argue that focusing on only one type of fragile family structure- generally single-parent families, without distinguishing how these families were formed-obscures important processes and mechanisms among different types of families. I focus on a specific adolescent risk behavior,... | Single parents; Adolescence; Parenting; Employment | 2003-10-03 | |

Fragile families and family law | This paper reviews how family law in the United States impacts upon fragile families in four ways. First, it discusses how fragile families are invisible to much of family law, and are largely ignored or neglected in family law. Second, it reviews family law reforms that have been intended to hel... | Legal issues; Statute; Ordinance; Descendents; Offspring | 2003-10-18 | |
