查询词典 dag

It is postulated that IP induces the release of endogenous protective molecules that interact with cognate receptors to activate PLC through mediation of the chincough virus sensitive proteins. PLC hydrolyzes membrane phospholipid and produces diacylglyccerol,that,by working together with calcium hydronium,translocates PKC from cytoplasm to cell membrane and activates PKC.

推测缺血预处理细胞保护作用机制是：缺血预处理引起内源性保护物质释放，作用于细胞膜上的相应受体，通过百日咳病毒敏感性G蛋白的介导而激活磷脂酶，磷脂酶水解膜磷脂，产生二酰基甘油(diacylglyccerol，DAG)，DAG和Ca2+协同作用于PKC，使其从胞浆转位到细胞膜并且被活化，PKC在膜上使底物蛋白磷酸化，引发一系列相关信号转导通路的激活，调控保护性基因的表达，从而提高细胞对缺血再灌注损伤的耐受性。

It solves the problem that the unitary contour presentation can not correctly extract face contour in a face image which suffers from scale, rotation etc. The definition of the internal and external energy function is provided. At the same time, the global matching algorithm and local matching algorithm is given. The experiment shows that this presentation and the accompanying matching algorithm can be used to extract the face contour very well. So the image segmentation can be implemented by using it.②By analyzing the recognition principle of PCA method, we can conclude that the face images coming from different surrounding consist of different face image space. This is the essential reason that makes the generality of PCA method worse. Also, we give a measurement means to measure the distance from different face image space, so we can analyze face image space more conveniently.③We also construct various scale models and rotation pose models to detect the scale and rotating angle of face image to be recognized. The experiment results show that the detecting precision is very high. So it is good for face image feature extraction and face image representation.④Similarly, we construct local feature models of face image and utilize them to detect the local feature of face image. At the same time, we put forward a novel face image local feature detection algorithm, locating step by step. The experiment results show that this method can accurately detect the location of local face feature in a image.⑤A novel face image presentation model, dual attribute graph , is put forward. Firstly, it utilizes attribute graph to present the face image, then exact the local principal component coefficient and Gabor transform coefficient of thc pixels which corresponds to the nodes of the graph as the attribute of the nodes. This representation fully makes use of the statistical characteristic of the local face feature and utilizes Gabor transform to present the topographical structure of face image. So DAG has more general property.⑥Based on the DAG presentation, we give a DAG matching function and matching algorithm. During the design of the function and algorithm, the noise factor, e. g., lighting, scale and rotation pose are considered and tried to be eliminated. So the algorithm can give more general property.⑦A general face image recognition system is implemented. The experiment show the system can get better recognition performance under the noise surrounding of lighting, scale and rotation pose.
