A novel surface-enhanced Raman scattering (SERS) probe was developed for selective determination of Hg(II) ion. It is based on the use of silver nanoparticles (Ag-NPs) modified with the dialkyne 1,4-diethynylbenzene (DEB). Hg(II) undergoes a very selective chemical reaction with the terminal ethynyl groups to form a –C ≡ C-Hg-C ≡ C– linkage which triggers the aggregation of Ag-NPs. This generates...
Traditional clustering ensemble methods combine all the obtained clustering results at hand. However, we can often achieve a better clustering solution if only a part of all available clustering results is combined. In this paper, SELective Spectral Clustering Ensemble (SELSCE), a novel clustering ensemble method, is proposed. The component clusterings of an ensemble system are generated by Spectral...
Method of information process based on test mining and segmentation technology is provided, which uses the relative principles in the filed of test mining and word segmentation to preprocess and transform the information from internet. The problem of large data dimension caused by the redundancy characters extracted from the test is settled and it improves the performance of the CE arithmetic. Finally,...
