PURPOSE RECK, a membrane-anchored regulator of matrix metalloproteinases (MMPs), is widely expressed in healthy tissue, whereas it is expressed at lower levels in many tumor-derived cell lines. Studies in mice and cultured cells have shown that restoration of RECK expression inhibits tumor invasion, metastasis, and angiogenesis. However, the clinical(More)
Abnormal traffic that causes various problems on the Internet, such as P2P flows, DDoS attacks, and Internet worms, is increasing; therefore, the importance of methods that identify and control abnormal traffic is also increasing. Though the application of frequent-itemset-mining techniques is a promising way to analyze Internet traffic, the huge amount of(More)
In this paper, future requirements we believe that will be needed for achieving power efficient routers are shown. The optical backplane is a proposal technology we are working on, which enables a high-speed and power efficient data transmission in backplane of routers and switches, by connecting the electronic devices together with optical paths. It is(More)
With a goal of contributing to multiparty conversation management, this paper proposes a mechanism for estimating conversational dominance in group interaction. Based on our corpus analysis, we have already established a regression model for dominance estimation using speech and gaze information. In this study, we implement the model as a dominance(More)
BACKGROUND Exacerbation of asthma has a negative impact on quality of life and increases the risk of fatal asthma. One of the known risk factors for patients with a history of near-fatal asthma is reduced sensitivity to dyspnea. OBJECTIVE We aimed to identify patients with such risk before they experienced severe exacerbation of asthma. METHODS We(More)
