An algorithm is given which makes only $O(\log n)$ comparisons, and which will determine the ordering of the uniformly distributed (pseudo random) Weyl sequences given by $\{ (k\alpha )\bmod 1:1 \leqq k \leqq n\} $, where $\alpha $ is an unspecified irrational number. This result is shown to be best possible in the sense that no algorithm can perform the same task with fewer than $ \Omega (\log...

Shared-memory multiprocessor (SMP) machines have become widely available. As the user community grows, so does the importance of compilers that can translate standard, sequential programs onto this machine class. Substantial research has been done to develop sophisticated parallelization techniques, which can detect and exploit parallelism in many real applications. However, the performance of ...

We present the results of a multiwavelength campaign for Mrk 501 performed in March 1996 with ASCA, EGRET , Whipple, and optical telescopes. The X–ray flux observed with ASCA was 5 times higher than the quiescent level and gradually decreased by a factor of 2 during the observation in March 1996. In the X–ray band, a spectral break was observed around 2 keV. We report here for the first time th...

Background: OX40 is a crucial T-cell costimulatory molecule, but its molecular characteristics remain unclear in diffuse large B-cell lymphoma (DLBCL). Methods: We performed an integrative analysis of gene expression, somatic mutations and multiplex immunofluorescence to characterize the features, tumor immune microenvironment (TiME) clinical outcomes. Results: first identified that abnormally ...

PURPOSE: Resection of exocrine pancreatic cancer is necessary for cure, but most patients subsequently develop progressive disease. In prospective trials, rates of local-regional failure (LRF) range from 20% to 40%. We evaluated our institutional experience to better understand the risk factors for LRF and the impact on overall survival (OS). METHODS: We reviewed 665 consecutive patients with n...

We provide a link between topological graph theory and pseudoline arrangements from the theory of oriented matroids. We investigate and generalize a function f that assigns to each simple pseudoline arrangement with an even number of elements a pair of complete-graph embeddings on a surface. Each element of the pair keeps the information of the oriented matroid we started with. We call a simple...
