Pivot translation is a useful method for translating between languages with little or no parallel data by utilizing parallel data in an intermediate language such as English. A popular approach for pivot translation used in phrase-based or tree-based translation models combines source-pivot and pivot-target translation models into a source-target model, as known as triangulation. However, this ...

Tilting pad journal bearings (TPJBs) are widely applied in the high-speed rotor system whose working speed is higher than its critical due to excellent hydrodynamic lubrication and stability. Pivot stiffness one of key design parameters TPJBs compared other has become particularly important for optimizing performance TPJB-rotor systems. In order improve vibration characteristics systems, transi...

The new dual-pivot Quicksort by Vladimir Yaroslavskiy — used in Oracle’s Java runtime library since version 7 — features intriguing asymmetries in its behavior. They were shown to cause a basic variant of this algorithm to use less comparisons than classic single-pivot Quicksort implementations. In this paper, we extend the analysis to the case where the two pivots are chosen as fixed order sta...

In this paper we generalize the so called rst in last out pivot rule and the most often selected variable pivot rule for the simplex method as proposed in Zhang to the criss cross pivot setting where neither the primal nor the dual feasibility is preserved The nite ness of the new criss cross pivot variants is proven

Metric-space indexing is a general method for similarity queries of complex data. The quality of the index tree is a critical factor of the query performance. Bulkloading a metricspace indexing tree can be represented by two recursive steps, pivot selection and data partition, while pivot selection dominants the quality of the index tree. Two heuristics, based on covariance and correlation, for...

To overcome the scarceness of bilingual corpora for some language pairs in machine translation, pivot-based SMT uses pivot language as a "bridge" to generate source-target translation from sourcepivot and pivot-target translation. One of the key issues is to estimate the probabilities for the generated phrase pairs. In this paper, we present a novel approach to calculate the translation probabi...

BACKGROUND The presence of a positive pivot shift after surgical repair of the ACL is considered an important indicator of a failed reconstruction. The ability to predict the result of a pivot shift test after an ACL reconstruction using variables that can be measured prior to surgery could provide an indication of which patients may be at-risk of a poor surgical outcome.The purpose of this stu...

In the Prostate Cancer Intervention Versus Observation Trial (PIVOT), surgery was not associated with lower mortality compared with observation. However, the high competing mortality rate of approximately 33% after 10 yr among the PIVOT study population has raised concerns on the generalizability of these results. We investigated 4282 patients who underwent radical prostatectomy at our institut...
