Two linear time (and hence asymptotically optimal) algorithms for computing the Euclidean distance transform of a two-dimensional binary image are presented. The algorithms are based on the construction and regular sampling of the Voronoi diagram whose sites consist of the unit (feature) pixels in the image. The rst algorithm, which is of primarily(More)
We report on two children with cerebral gliomas showing extensive lipomatous change of tumor cells. One tumor was a large mass occupying the temporal and occipital lobes of the left hemisphere; the other was a cystic lesion with a mural nodule in the left frontal lobe. Histologically, both tumors were composed of glial cells that contained fat droplets(More)
19 children and adolescents with intracranial tumors received a palliative therapy with H 15 at a maximum dose of 126 mg/kg BW/day. All patients had previously been treated with conventional therapy. No side effects were observed during a median 9 months application. The recently reported antiedematous effect of H 15 was documented by MRI in one patient(More)
High-throughput RNA sequencing enables quantification of transcripts (both known and novel), exon/exon junctions and fusions of exons from different genes. Discovery of gene fusions-particularly those expressed with low abundance- is a challenge with short- and medium-length sequencing reads. To address this challenge, we implemented an RNA-Seq mapping(More)
We observed a fatal meningoencephalitis in a patient who suffered from acute lymphatic leukemia. The infection occurred after complete bone marrow remission. As the cause of this complication we discovered a rubella-infection, whose beginning had been several weeks ago. Relations to several forms of rubella-encephalitis in otherwise healthy patients are(More)
