BACKGROUND Attention-deficit hyperactivity disorder (ADHD) is the most common mental and behavioral disorder in school-aged children. This study evaluated the effect of osmotic-release oral system (OROS) methylphenidate (MPH) on cognitive function and academic performance of Chinese school-aged children with ADHD. METHODS This 12-week, prospective,(More)
Saliency detection is one of the extraordinary abilities of the human visual system (HVS), and also provides a powerful tool for predicting where humans tend to focus in the free-viewing process. In this paper, we propose a novel method for computing image saliency. At first, an image is subject to L<sub>0</sub> smoothing to characterize its fundamental(More)
A novel approach to heterocyclic enamines has been developed from the formal ring transformation reaction of lactones. The synthesis comprises consecutive Reformatsky reaction of lactones and mesylation of the resulting mixture of ring-chain tautomers in a one-pot reaction, followed by cyclocondensation reaction with primary amines. The synthetic(More)
A novel computational model for detecting salient regions in color images is proposed by utilizing early visual features and performing spectral normalization in the octonion algebra framework, which can accommodate more feature channels than quaternions can. Firstly, feature maps based on edge intensity, the black-white, red-green, and blue-yellow color(More)
A novel computational model for detecting salient regions in color images is proposed, based on a two-stage coarse-to-fine framework. Firstly, different early visual feature maps - including the edge intensity; the black-white, red-green, and blue-yellow color opponents; and the Gabor features with four directions - are incorporated into the eight channels(More)
Saliency detection is one of the extraordinary abilities of the human visual system; it also provides a powerful tool for predicting where people tend to focus in the free-viewing process. In this paper, we propose a novel salient-object detection method which applies an over-segmentation-based saliency detection algorithm to multi-level smoothed images.(More)
