Improving the effectiveness of POI search by associated information summarization
The demand for map services has risen significantly in recent years due to the popularity of mobile devices and wireless networks. Since there are always emerging point-of-interest (POI) in the real world, mining POIs shared by users from the Web has been a challenging problem to enrich existing POI database. However, crawling address-bearing pages and extracting POI relations are only the fundamentals for constructing POI database, the description of POIs, i.e. the services and products that POIs provide are especially essential for POI search. In this paper, we propose the summarization of POI associated information to improve the search effectiveness to avoid mismatches between users' queries and the relevant POIs by integrating our constructed POI database with Google place API to collect POIs shared by users from the Web. Experimental results showed that the integrated POI search service outperforms other similar servicess, such as Wikimapia and a commercial app, What's the number.
Fabrication of PLLA/C3S Composite Membrane for the Prevention of Bone Cement Leakage
Kyphoplasty is an important treatment for stabilizing spine fractures due to osteoporosis. However, leakage of polymethyl-methacrylate (PMMA) bone cement during this procedure into the spinal canal has been reported to cause many adverse effects. In this study, we prepared an implantable membrane to serve as a barrier that avoids PMMA cement leakage during kyphoplasty procedures through a hybrid composite made of poly-l-lactic acid (PLLA) and tricalcium silicate (C3S), with the addition of C3S into PLLA matrix, showing enhanced mechanical and anti-degradation properties while keeping good cytocompatibility when compared to PLLA alone and most importantly, when this material design was applied under standardized PMMA cement injection conditions, no posterior wall leakage was observed after the kyphoplasty procedure in pig lumbar vertebral bone models. Testing results assess its effectiveness for clinical practice.
