CASE PRESENTATION A 21-year-old woman with a history of BE and ureteral reimplantation, presented with hematuria-dysuria syndrome and recurrent febrile urinary tract infections. After counselling, she elected to undergo bi...
متن کاملLogarithmic Tapering Graph Pyramid
We present a new method to determine contraction kernels for the construction of graph pyramids. The new method works with undirected graphs and yields a reduction factor of at least 2.0. This means that with our method the number of vertices in the subgraph induced by any set of contractible edges is reduced to half or less by a single parallel contraction. Our method yields better reduction f...
متن کاملTRANS URETERAL LITHOTRIPSY
From Sep. 1984 to Aug. 1990,99 patients were treated for ureteral stone using the urekroscope. In five patients ureteroscopy was repeated for a second stone. In one patient the procedure was diagnostic in nature and in the rest of the patients it had a curative value. In 60 patients the stone was removed by electrohydraulic and basket combination and in25 cases, dilatation alone was enough...
متن کاملCovariance Tapering in Spatial Statistics
In the analysis of spatial data, the inverse of the covariance matrix needs to be calculated. For example, the inverse is needed for best linear unbiased prediction or kriging, and is repeatedly calculated in the maximum likelihood estimation or the Bayesian inferences. Since the spatial sample size can be quite large, operations on the large covariance matrix can be a numerical challenge if no...
متن کاملBenzodiazepine tapering: a prospective study.
BACKGROUND Benzodiazepines (BZD) are the most widely used sedative-hypnotics, and evidence is rapidly accumulating suggesting potential BZD dependence, association of chronic use with adverse effects and a definite abstinence syndrome produced by withdrawal. AIMS The present investigation followed prospectively long-term BZD users over 1 year following graded BZD withdrawal in terms of clinic...
