The ANN-based algorithms have been developed based on a constraint condition, which represents, to a certain degree, the correlation between suspended particulate matter (SPM) and pigment (CHL), coloured dissolved organic matter (CDOM) and CHL, as well as CDOM and SPM, found in Case Ⅱ waters. Compared with the ANN-based algorithm developed without a constraint condition, the performance of ANN-based algorithms developed with a constraint conditions is much better for the retrieval of CHL and CDOM, especially in the case of high noise levels; however, there is not significant improvement for the retrieval of SPM.展开更多

Methods: A total of 6 cases of volunteer healthy subjects (3 males and 3 females) ranging in age from 22 to 36 years were subjected to this study. Changes of cerebral glucose metabolism before and after electro-scalp acupuncture were observed by using positron emission tomography (PET) and semi-quantifying analysis method. Electro-scalp acupuncture stimulation (50 Hz, 2 mA) of Middle Line of Vertex (Ding zhongxian,顶中线,MS5), Middle Line of Forehead (Ezhongxian, 额中线,MS1) and bilateral Lateral Line 1 of Forehead (Epangyixian,额旁一线,MS2) was administered for 30 minutes. Then cerebral regions of interest (ROIs) were chosen and their average glucose metabolism levels (radioactivity of 18 fluorine deoxyglucose) were analyzed. Results: After administration of electro-scalp acupuncture, the glucose metabolism levels in bilateral frontal lobes and bilateral caudate nuclei, left cingulate gyrus and right cerebellum increased significantly in comparison with those of pre stimulation (P<0.05). Conclusion: Electro-scalp acupuncture of MSI, MS2 and MS5 can increase the glucose metabolism of certain cerebral regions involving mental activity in healthy subjects.展开更多

Cultural difference or even conflict is one of the inevitable issues in terms of migration. The Chinese （Han） culture which belongs to the continental civilization and the Australian （Western） culture which belongs to the maritime one are both mighty and cannot be conquered or assimilated by each other. This means that the Chinese immigrants to Australia, compared to the ones from a less mighty culture, are more sensitive and resistant to the impact of an alien culture, which leads to a conscious or unconscious sense of security of the mother culture. Cultural security, not unidirectional, also refers to the worry by the locals of the impact brought by the immigrants.
