Total internal reflection fluorescence (TIRF) microscopy excites a thin evanescent field which theoretically decays exponentially. Each TIRF image is actually the projection of a 3-D volume and hence cannot alone produce an accurate localization of structures in the z-dimension, however, it provides greatly improved axial resolution for biological samples. Multiple angle-TIRF microscopy allows controlled...
On the basis of NOAA monthly OLR data and Chinese National Climate Center precipitation data of 160 stations from 1979 to 2007, the spatial and temporal characteristics of winter convection activity over Tropical Indian Ocean and Pacific Ocean (TIOPO) and its relationship with subsequent summer precipitation over China have been analyzed. The results show that the winter convection activity has weakened...
In this paper, different from usual order, not directly use the maximal forward reference path to mine sequence patterns but use DBSCAN algorithm to cluster the Web pages that have been accessed by users. Then, decide the Web page class that each page belongs to based on heuristic rules. Next, cluster the users who have the same interest in one or some kinds of Web pages. One user can belong to several...
