Zhang, Kang | Spectrum and frequency of FZD4 mutations in familial exudative vitreoretinopathy | Mutations in the frizzled-4 gene (FZD4) have recently been associated with autosomal dominant familial exudative vitreoretinopathy (FEVR) in families linking to the EVR1 locus on the long arm of chromosome 11. The purpose of this study was to screen FZD4 in a panel of 40 patients with FEVR to ident... | Frizzled-4 gene; FZD4; Mutation; autosomal dominant familial exudative autosomal dominant familial exudative; FEVR | 2004 |

Schmidt, Meic H. | Spinal epidural lipomatosis: a review of its causes and recommendations for treatment | Spinal epidural lipomatosis is most commonly observed in patients receiving long-term exogenous steroid therapy, but can also be seen in patients with endogenous steroid overproduction, obesity, or idiopathic disease. With this condition, there is hypertrophy of the epidural adipose tissue, causing ... | Spinal epidural lipomatosis; Steroid; Hypertrophy; Adipose tissue | 2004 |

Ehleringer, James R.; Rickart, Eric Allan; Dearing, Maria-Denise | Stable isotope ratios (?15N AND ?13C) of syntopic shrews (SOREX) | Local species richness in shrew (Soricidae) assemblages is often high, and the mechanisms of ecological separation remain relatively unexplored. In this study, hair samples from 6 species of Sorex in 3 separate assemblages were analyzed for stable carbon (13C/12C) and nitrogen (15N/14N) isotope rati... | | 2004 |

Mathews, V. John | Stochastic mean-square performance analysis of an adaptive Hammerstein filter | ABSTRACT This paper presents an almost sure (a.s.) mean-square performance analysis of an adaptive Hammerstein filter for the case when the measurement noise in the desired response signal is a martingale difference sequence.

Williams, Clayton C. | Sub-10 nm lateral spatial resolution in scanning capacitance microscopy achieved with solid platinum probes | Sub-10 nm resolution can be obtained in scanning capacitance microscopy (SCM) if the probe tip is approximately of the same size. Such resolution is observed, although infrequently, with present commercially available probes. To acquire routine sub-10 nm resolution, a solid Pt metal probe has bee... | | 2004 |

Couldwell, William T.; House, Paul A.; Salzman, Karen L.; Osborne, Anne G.; MacDonald, Joel D.; Jensen, Randy L. | Surgical considerations regarding giant dilations of the perivascular spaces | Object. Dilations of brain perivascular spaces (PVSs), also known as Virchow-Robin spaces, are routinely identified on magnetic resonance imaging studies of the brain and recognized as benign normal variants.

Myers, Chris J. | Synthesis of speed independent circuits based on decomposition | This paper presents a decomposition method for speedindependent circuit design that is capable of significantly reducing the cost of synthesis. In particular, this method synthesizes each output individually. It begins by contracting the STG to include only transitions on the output of interest and ... | | 2004 |

Eddings, Eric G.; Sarofim, Adel F. | Thermal behavior of a high-energy material immersed in a fire | One of the uncertainties in the calculations of time-to-explosion for containers of high-energy materials immersed in fires is that of the thermal boundary at the container-explosive interface. Understanding this interface is critical in evaluating risks, safety issues and prevention mechanisms. In ... | | 2004 |

Miller, Jan D. | Three dimensional analysis of particulates in mineral processing systems by cone beam X-ray microtomography | In general, X-ray-computed tomographic (CT) techniques are capable of providing three-dimensional images of the internal structure of opaque materials in a nondestructive manner. The unique cone beam geometry allows acquisition of all two-dimensional projections with only one rotation of the sample,... | Cone beam CT; X-ray microtomography; Liberation analysis; Particle shape; Heap leaching; Exposure analysis; Coal washability | 2004 |

Zhdanov, Michael S. | Three-dimensional regularized focusing inversion of gravity gradient tensor component data | We develop a new method for interpretation of tensor gravity field component data, based on regularized focusing inversion. The focusing inversion makes its possible to reconstruct a sharper image of the geological target than conventional maximum smoothness inversion. This new technique can be eff... | Focusing inversion; Gravity gradient; Gravity gradiometry | 2004 |

Hawken, Leanne Sue | Using DIBELS to improve reading outcomes | Students' reading trajectories (i.e., their general pattern of reading progress) are established early and are relatively stable over time. For example, students who are poor readers in first grade are likely (i.e., 88%) to be poor readers in fourth-grade. Prevention is key to improving reading out... | | 2004 |
