The cellular and subcellular distributions of mRNAs encoding three myelin-specific proteins--myelin basic protein (MBP), proteolipid protein (PLP), and Po protein--were studied in tissue sections of developing rat nervous systems by in situ hybridization. The developmental appearance of these mRNAs closely paralleled the appearance of the proteins they(More)
Feline immunodeficiency virus, like human immunodeficiency virus type 1, is a retrolentivirus causing neurological disease and immune suppression. Primary neurological complications, including human immunodeficiency virus encephalopathy and peripheral neuropathy, and neuropathological changes, including gliosis, neuronal injury and multinucleated giant(More)
In functional MRI (fMRI) complex experiments and applications require increasingly complex parameter handling as the experimental setup usually consists of separated soft- and hardware systems. Advanced real-time applications such as neurofeedback-based training or brain computer interfaces (BCIs) may even require adaptive changes of the paradigms and(More)
Line drawing techniques are important methods to illustrate shapes. Existing feature line methods, e.g., suggestive contours, apparent ridges, or photic extremum lines, solely determine salient regions and illustrate them with separate lines. Hatching methods convey the shape by drawing a wealth of lines on the whole surface. Both approaches are often not(More)
Smoothing algorithms allow to reduce artifacts from mesh generation, but often degrade accuracy. Thus, we present a method that identifies staircase artifacts which result from image inhomogeneities and binary segmentation in medical image data for subsequent removal by adaptive mesh smoothing. This paper makes the following specific contributions: caps,(More)
For the computer-aided diagnosis of tumor diseases knowledge about the position, size and type of the lymph nodes is needed to compute the tumor classification (TNM). For the computer-aided planning of subsequent surgeries like the Neck Dissection spatial information about the lymph nodes is also important. Thus, an efficient and exact segmentation method(More)
Surface models derived from medical image data often exhibit artifacts, such as noise and staircases, which can be reduced by applying mesh smoothing filters. Usually, an iterative adaption of smoothing parameters to the specific data and continuous re-evaluation of accuracy and curvature is required. Depending on the number of vertices and the filter(More)
We investigate intermediary asset pricing theories empirically and find strong support for intermediary book leverage as the relevant state variable. A parsimonious dynamic pricing model that uses detrended broker-dealer leverage as a price of risk variable, and innovations to broker-dealer leverage as pricing factor is shown to perform well in time series(More)
