—Many researchers have argued that data mining can improve the performance of intrusion detection system. So as one of important techniques of data mining, clustering is an important means for intrusion detection. Due to the disadvantages of traditional clustering methods for intrusion detection, this paper presents a graph-based intrusion detection(More)
BACKGROUND Little is known about the influence of the site of research or publication on the impact of the research findings on clinical practice, particularly in developing countries. The International Clinical Epidemiology Network (INCLEN) is dedicated to improving the quality of health research in the Developing World through institutional capacity(More)
Amyloid β(Aβ) peptides are important components of plaques in Alzheimer's disease(AD). A decrease in the CSF concentration of Aβ40 and Aβ42 is a potential biomarker for incident AD. In contrast, studies on plasma Aβ40 and Aβ42 concentrations have yielded contradictory results. To explore the relationship between plasma Aβ40 and Aβ42 concentrations and AD in(More)

This paper considers the strategic motivation and performance of Chinese cross-border M&A activities of 27 deals which took place in Shanghai and Shenzhen stock markets in the period of 2000 – 2004. The study finds that cross border M&As formation by Chinese firms are primarily motivated by market development, that is, increasing market share, to enable(More)
OBJECTIVE The purpose of this study was to evaluate the accuracy of contrast-enhanced magnetic resonance angiography for the diagnosis of congenital obstructive aortic arch anomalies in children and compare it with transthoracic echocardiography and other MR imaging techniques (ECG gated T1-weighted spin-echo imaging and gradient-echo cine imaging).

Ras association domain family 1A gene (RASSFlA) is a candidate suppressor gene, Lack of RASSF1A expression was found in lung cancer. High DNA methylation at the promoter region is the main reason for inactivating RASSF1A transcription. In this study, we examined RASSF1A’s methylation status and its mRNA expression level between non-small cell lung cancer(More)
" Beijing 1 " is one Micro-satellite of the international Disaster Monitoring Constellation (DMC). It was launched successfully in 2005, and has high-powered characteristic, such as high gaining data ability, high storage ability, high space resolution, high time resolution and low cost. At present it is necessary to make objective appraisal for image(More)
Mobile Agent is one of the most promising technologies of distributed computing. Mobile Agent does have certain properties, such as autonomy, mobility and most of all, it fits well in the low-bandwidth network environments. This paper mainly provides a prototype for information retrieval in a virtual enterprise using Mobile Agent. The prototype best(More)
This paper interpreted the visual construction of tobacco control public service ads from the perspective of multimodal discourse analysis. It analyzed the dilemma of tobacco control, made interpretation of images in the public service ads from three perspectives, namely, reproduction sense, interactive sense and composition sense. With the case study of(More)
