in this study, we examined the antioxidant activities of methanolic extract of three endemic species of salvia from iran (s. lachnocalyx, s. reuterana and s. sahendica) employing various established in vitro systems including ferric reducing antioxidant power, trolox equivalent antioxidant capacity assay and scavenging of 1,1-diphenyl-2-picrylhydrazyl radical. the results revealed that s. reute...

Objective: This study is to determine the effect and mechanism of salvia extract on angiogenesis of the myocardium in rats with myocardial infarction (MI). Methods: Left coronary artery of Sprague-Dawley rats was ligated to establish MI model. Forty rats were randomly divided into five groups: sham operation group, MI model group, and three salvia extract groups (10, 20, 40 mg/kg/day), with eac...

In this paper we apply data envelopment analysis (DEA) to evaluate the performance of hedge fund classifications. The purpose of alternative investment strategies such as hedge funds is to offer absolute returns, so using passive benchmarks to measure their performance could be ineffective. With the increasing number of hedge funds available, institutional investors, pension funds, and high net...

ince the early 1990s, hedge funds have become an increasingly popular asset class. The amount invested globally in hedge funds rose from approximately $50 billion in 1990 to approximately $1 trillion by the end of 2004.1 And because these funds characteristically use substantial leverage, they play a far more important role in the global securities markets than the size of their net assets indi...

In this paper, we proposed a hedge detection method with average perceptron, which was used in the closed challenge in CoNLL-2010 Shared Task. There are two subtasks: (1) detecting uncertain sentences and (2) identifying the in-sentence scopes of hedge cues. We use the unified learning algorithm for both subtasks since that the hedge score of sentence can be decomposed into scores of the words,...

Hedge fund families face diseconomies of scale because of the non-scalability of their investment strategies. We propose that as the existing funds approach critical size, hedge fund families may prefer opening new funds rather than accepting new investment in the existing f...
