We provide efficient support for applications that aim to continuously find pairs of similar sets in rapid streams of sets. A prototypical example setting is that of tweets. A tweet is a set of words, and Twitter emits about half a billion tweets per day. Our solution makes it possible to efficiently maintain the top-k most similar tweets from a pair of rapid Twitter streams, e.g., to discover ...

mechanical thrombectomy has shown promising results in large vessel ischemic stroke, with recent large trials changing to guidelines worldwide. in this presentation, results from the five recent randomized trials will be discussed. there is an ongoing debate on the inclusion and exclusion criteria of mechanical thrombectomy. it can be done in large vessel occlusions, including up to m2 middle c...

HYPOTHESIS The approach to pericardial window in patients with nontraumatic pericardial effusion impacts outcome. DESIGN Retrospective review and comparison of all cases of pericardial window performed over 10 years. Follow-up was to patient death. SETTING Three hospitals performing cardiothoracic surgery at a single university. PATIENTS All patients in whom pericardial window was perform...

Dynamic Time Warping (DTW) is used to find alignments between two related streams of information and can be used to link data, recognise patterns or find similarities. Typically, DTW requires the complete series of both input streams in advance and has quadratic time and space requirements. As such DTW is unsuitable for real-time applications and is inefficient for aligning long sequences. We p...

Sliding-window aggregation is a widely-used approach for extracting insights from the most recent portion of data stream. While aggregations interest can usually be expressed as binary operators that are associative, they not necessarily commutative nor invertible. Non-invertible operators, however, difficult to support efficiently. DABA first algorithm sliding-window with worst-case constant t...

Feedback linearization is worked out for nonlinear time-delay systems and it shown that even if the problem can not be solved all time, may still over some time windows. The solution then reduces to a discontinuous state feedback. It foreseen such piecewise feedback instrumental stabilization by control, although scope of this paper. approach used herein address other classical control problems...
