The coverage of modalities in retrieved results seems to be an important part of the user’s information need. We show that this problematic is not satisfied by ...

The proposed social media crowdsourcing platform leverages the existing social networking applications to rapidly allocate microtasks to a wide network of crowdworkers, and visualizes the geotagged result data in order to create a sort of visual information pool for pu...

BACKGROUND Atherosclerotic lesions contain foam cells that arise from monocyte-macrophages and smooth muscle cells (SMCs) by excessive uptake of lipoproteins. There are many candidate receptors for the lipid accumulation, such as LDL receptor (LDLR), VLDL receptor (VLDLR), LDL receptor-related protein (LRP), and scavenger receptors (SRs). However, little quantitative information exists on the e...
