Predicting CAP-related mortality with CRB-65.
Predicting CAP-related mortality with CRB-65 Ewig et al are to be commended for their very large study of 388 406 patients admitted with community-acquired pneumonia (CAP) in German hospitals from 2005 to 2006. Using the CRB-65 tool (confusion, respiratory rate $30 min, low blood pressure (either systolic <90 mm Hg or diastolic #60 mm Hg) and age $65 years), the authors found 30-day mortality r...
متن کاملAn Intelligent Tool Selection System Based on CRB and RBR
The manufacturing industries dealing with machining and tools' manufacturing generate a large amount of data concerning the machining process. However, in most cases, this information is not used in an advantageous strategy as there is no system dedicated for storing and manipulating such data. In order to Use these data to improve efficiency and increase benefit of machining, the cutting datab...
متن کاملThe stochastic CRB for array processing in unknown noise fields
The stochastic Cramér-Rao bound (CRB) plays an important role in array processing because several high-resolution direction-ofarrival (DOA) estimation methods are known to achieve this bound asymptotically. In this paper, we study the stochastic CRB on DOA estimation accuracy in the general case of arbitrary unknown noise field parametrized by a vector of unknowns. We derive explicit closed-for...
متن کاملCRB-Tree: An Efficient Indexing Scheme for Range-Aggregate Queries
We propose a new indexing scheme, called the CRB-tree, for efficiently answering range-aggregate queries. The range-aggregate problem is defined as follows: Given a set of weighted points in R, compute the aggregate of weights of points that lie inside a d-dimensional query rectangle. In this paper we focus on range-COUNT, SUM, AVG aggregates. First, we develop an indexing scheme for answering ...
متن کاملDiscovery of Optical Bursts from Ms1603.6+2600 = Uw Crb
We report the discovery of several optical burst-like events from the low-mass X-ray binary MS 1603.6+2600 (UW CrB). The events last for a few tens of seconds, exhibit a very fast rise and slow decay, and involve optical brightening of a factor of 2–3. The flares appear distinct from the lower level flickering and instead strongly resemble reprocessed type-I X-ray bursts as seen in a number of ...
