Background and Purpose—The present study was performed to determine the role of a4 (CD49d), a member of the integrin family of adhesion molecules, in ischemic brain pathology. Methods—Male spontaneously hypertensive rats (SHR) or Sprague-Dawley rats underwent 60-minute middle cerebral artery occlusion (MCAO) followed by 23-hour reperfusion. Animals were injected intravenously with 2.5 mg/kg ant...

BACKGROUND This study compared surgical outcomes of patients with previous cardiac surgery undergoing transapical transcatheter aortic valve implantation (PCS-TA-TAVI) with those of patients undergoing transapical transcatheter aortic valve implantation as an initial procedure (initial TA-TAVI) by using propensity analysis. METHODS From January 2005 through January 2013, 267 consecutive high-...

The large amount of available multimedia information (e.g. videos, audio, images) requires eecient and eeec-tive annotation and retrieval methods. As videos start playing a more important role in the frame of multimedia, we want to make these available for content-based retrieval. The ImageMiner-System, which was developed at the University of Bremen in the AI group, is designed for content-bas...

In this paper, a research design for the analysis of the type and extent of the consideration of the social and technical factor in the IS literature is developed. The objective of the analysis is an empirical contribution to the ongoing discourse about the “core” of the IS discipline. Its goal is to provide insight whether the proposed directions for IS research of the past are reflected in ch...

The antibiotic TA of Myxococcus xanthus is a complex macrocyclic polyketide, produced through successive condensations of acetate by a type I PKS (polyketide synthase) mechanism. The genes encoding TA biosynthesis are clustered on a 36 kb DNA fragment, which has been cloned and analysed. The chemical structure of TA and the mechanism by which it is synthesized indicate the need for several post...

Due to rapid technological innovation and global competitiveness, the component cost, the selling price and the demand rate of Hi-tech industries (such as computers and communication consumer’s products) usually decline significantly with time. From a practical viewpoint, there is a need to develop a replenishing policy with finite horizon when the component cost, the selling price and the dema...

Technical analysis is the forecasting of future price movement based on an examination of past prices. Some scientist found that the study of historical prices cannot predict future prices. In this research we intend to study which technical analysis tool is better for prediction of future price movement, for this purpose we are studying two the most strongest technical analysis tools is called...

Partial objectives include analysis of metric characteristics of the measuring instrument, and determining differences between two disciplines (sparri...

During the last years, the concept of input congestion and technical ineff-ciency in data envelopment analysis (DEA), have been investigated by manyresearchers. The motivation of this paper is to present models which obtain thedecreased output value due to input congestion and technical ineciency. More-over, we extend the models to estimate input congestion, technical ineciencyand output reduct...

In this paper I will shed new light on the semantics of Japanese tense-aspect markers ta and teiru from dynamic semantics and contrastive perspectives. The focus of investigation will be on the essential difference between ta and teiru used in an aspectual sense related to a perfect. I analyze the asymmetry between ta and teiru with empirical data and illustrate it in the DRT framework (Discour...
