With the development of the internet, medical images are now available in large numbers in online repositories, and there exists the need to retrieval the medical images in the content-based ways through automatically extracting visual information of the medical images. Since a single feature extracted from images just characterizes certain aspect of image content, multiple features are necessa...

Granseth et al. argue that vesicle retrieval at hippocampal synapses is fully accounted for by a single mode of endocytosis. However, their assay focused on readily releasable pool vesicles (RRP), not RRP + reserve pool vesicles in tandem, and therefore cannot detect pool-dependent changes in vesicle-retrieval kinetics during a stimulus train. Using a probe similar to theirs, we observed rapid ...

Advanced information retrieval and database management systems employ a variety of elaborate data representation, indexing and retrieval techniques, but usually apply less elaborate – often simplistic – models of the human-computer interaction. Effective interaction, however, is essential for effective information retrieval. To be able to assist and guide the user actively through the entire in...
