Contextual modulation is a universal phenomenon in the primary visual cortex (V1). It is often allocated to the two categories of suppression and facilitation, which are either weakened or strengthened by the contextual stimuli, respectively. A number of experiments in neurophysiology have elucidated their important functions in visual information(More)
Knowledge of protein-protein interactions and their binding sites is indispensable for in-depth understanding of the networks in living cells. With the avalanche of protein sequences generated in the postgenomic age, it is critical to develop computational methods for identifying in a timely fashion the protein-protein binding sites (PPBSs) based on the(More)
The mechanism for silicon-mediated salt tolerance is still not very clear. The aim of this study was to investigate the possible role of silicon in regulating carbohydrate metabolism in cucumber (Cucumis sativus L.). Two cucumber cultivars (‘JinYou 1’ and ‘JinChun 5’) grown hydroponically were subjected to 75 mM NaCl stress in the absence or presence of(More)
Cerebral amyloid angiopathy (CAA) is a disorder affecting the elderly that is characterized by amyloid-β (Aβ) deposition in blood vessel walls of the brain. A series of 99mTc(CO)3-labeled benzothiazole derivatives as potential SPECT imaging probes for cerebrovascular Aβ deposition is reported. Rhenium surrogate displayed high affinities to Aβ aggregates(More)
An unsupervised learning algorithm, named soft spectral clustering ensemble (SSCE), is proposed in this paper. Until now many proposed ensemble algorithms cannot be used on image data, even images of a mere 256 Â 256 pixels are too expensive in computational cost and storage. The proposed method is suitable for performing image segmentation and can, to some(More)
