It has been reported that chronic heroin intake induces both structural and functional changes in human brain; however, few studies have investigated the carry-over adverse effects on brain after heroin withdrawal. In this paper, we examined the neurophysiological differences between the abstinent heroin addicts (AHAs) and healthy controls (HCs) using nonlinear dynamic analysis and source localization...
It has been reported that chronic heroin intake induces changes in central nervous system of human brain; however, few studies investigate the carry-over adverse effects on brain after heroin withdrawal. In this work we examined the alpha rhythms of resting-state Electroencephalogram (EEG) signals to measure the neuroelectrical differences between the heroin addicts after heroin withdrawal and normal...
Medical image segmentation is the basis of medical image three-dimension reconstruction. The accuracy of image segmentation directly affects the results of image 3D reconstruction. Medical image is a kind of grayscale image. In order to adequately utilize gray information and spatial information of image, the traditional 2D gray histogram is improved and forms the 2D D-value attribute gray histogram...
Software maintainability means the ease with which a software system or component can be modified to correct faults, improve performance or other attributes, or adapt to a changed environment. For different software maintenance organizations or personnel, there are different concerns on software maintainability. If any one of the factors affecting the maintainability has not been completely resolved,...
In the evaluation process of digital libraries, there are many aspects needing to consider, with a lot of uncertainty and ambiguity, so it is reasonable and scientific to apply fuzzy comprehensive evaluation method for digital library fuzzy evaluation. The core of fuzzy evaluation is membership degree transformation. But the existing transformation methods should be questioned, because redundant data...
Product design case databases contain a lot potential knowledge, which can tell us the relations among parameters and some interesting experience patterns. While designing product, it is supposed to support the designers to make decisions better. Therefore many researchers are trying to find an effective approach to discover the unknown knowledge. In this paper, we presented several algorithms which...
