Identifying patterns in time series that exhibit anomalous behavior is of increasing importance in many domains, such as financial and Web data analysis. In real applications, time series data often arrive continuously, and usually only a single scan is allowed through the data. Batch learning and retrospective segmentation methods would not be well applicable to such scenarios. In this paper, ...

Aortic regurgitation was the commonest functional anomaly among younger patients in a group of 63 individuals with a diagnosis of bicuspid aortic valve. With increasing age, a rise in the number with combined aortic valve disease and aortic stenosis was observed. Aortic dilatation was found in 65% of cases. Dilatation was independently associated with age and transvalvular aortic gradient.

In practical applications of classification, there are often varying costs associated with different types of misclassification (e.g. fraud detection, anomaly detection and medical diagnosis), motivating the need for the so-called ”cost-sensitive” classification. In this paper, we introduce a family of novel boosting methods for cost-sensitive classification by applying the theory of gradient b...

Understanding the influence of El Niño–Southern Oscillation (ENSO) on North Atlantic (NAO) is critical significance for seasonal prediction. The present study found that both Niño3.4 sea surface temperature anomaly (SSTA) intensity and east-west gradient in mid-low latitude Pacific determine linkage between ENSO NAO. Based SSTA gradient, events are classified into three types: strong intensity,...

Increasing the efficiency of crushing circuits is associated with a decrease in particle size finely crushed ore and use dry magnetic separation ore. Reducing grinding costs achieved by using drum mills jointly other designs. The automation systems, slurry demagnetization, technologies staged concentrate separation, beneficiation fine screening closed cycle lead to reduction costs. main industr...

In recent years, some generalized structures of topology were introduced. Supra was one the most important those generalizations. To contribute in this orientation, we devoted work to studying limit points and separation axioms on supra topological spaces by using $b$-open sets. We define them a similar way their counterparts spaces. general, demonstrate main properties investigate sufficient c...

The break-up of the supercontinent Rodinia in late Neoproterozoic led to formation Nanhua rift basin within South China Block. Datangpo-type manganese deposit, which developed basin, is one most important types deposits China. Although it widely accepted that deep sedimentary structures significantly affect ore system, relationship between and rifting process still unclear. origin layer remains...
