Firstly, the paper, combining the characteristic of synchronous pulse bursts and inhibition with the modified PCNN model, presents a way of finding the foveation points in the images adaptively and effectively, and simulates the human vision system. Secondly, PCNN is extended to PCNNs, based on the properties of information couple and transmission, an algorithm that is used to fuse images of the same target got by several sensors to an image is presented to simulate the human vision system. Thirdly, combining the properties of synchronous pulse bursts, capture, and transmission and competition of waves, the paper presents two ways of classification, one is an algorithm based on the properties of neuron to capture and inhibit to classify the data taking on any complex unlinear distribution robustly, the other is based on the restricted distance and modified of the former to remove the influence of inferior samples in classification; Finally, based on the accumulative difference pictures, and the forming and transmission of PCNN wave, selecting and controlling the direction of autowave by connecting the neighbouring neurons selectively, the paper presents a way to simulate the tracks of moving object and detect the moving direction.

The results of numerical analysis show that the elastic modular and the poisson ratio have no effect on two-dimensional bearing capacity, but can affect the ultimate bearing capacity of three-dimensional foundations and control the convergence and precision of finite element calculation; the earth pressure coefficient controls the geostatic stress of foundation, sequentially affects the ultimate bearing capacity of foundations and the convergence of numerical calculation. When calculating the ultimate bearing capacity of undrained saturated foundation, the complete formulation exists shear locking, and reduce formulation exists hourglassing, so the hybrid formulation is suitable to imitate the geomaterial. When the soil obeys nonrelevent flow rule, the yielding function is different from potential function, and the elastic-plastic matrix of soil is asymmetric, so the unsymmetry numerical solver and appropriate finite element mesh is required.
研究结果表明,土体弹性模量和泊松比对二维基础极限承载力没有影响,但是影响着三维矩形基础的极限承载力,控制着ABAQUS数值算法的计算精度与收敛速度;地基土压力系数控制着地基土体中的地应力平衡,从而影响着二维条形基础和三维矩形基础的极限承载力和地基破坏包络面;对于不排水饱和软黏土地基,常规的完全积分单元会造成剪力自锁现象,而减缩积分单元则存在过于柔化的现象,故采用杂交单元来模拟较合适;当土体服从非关联流动法则时,屈服函数与塑性势函数之间存在差异,从而导致土体弹塑性矩阵呈现非对称性,在有限元计算中必须采用非对称数值解法,并且合理地划分单元才能对极限承载力进行准确求解。

The PSCA_3 fragment was selected for its superior expression level in eukaryotic cells.Then the sig-PSCA_3-Fc-GPI genetic fragment was cloned into pVAX1-neo-IRES-GM/B7 vector to construct the final immunological inhanced DNA vaccine pVAX1-PSCA_3-FcGB. Immunofluorescence and flow cytometry were used to confirm the expression of PSCA_3 fragment by transfected into Cos7 cell.Finally,the anti-tumor effect of pVAX1-PSCA_3-FcGB was tested in murine prostate cancer model generated by RM-1 cell line.The animal was immunized with pVAX1-PSCA_3-FcGB DNA vaccine by intramuscular injection plus electroporation,pVAX1 and pVAX1-PSCA_1-FcGB plasmid were used as control.The inhibitory effect of tumor was investigated by observion of forming time,volume and inhibition ratio of tumor.Results:DNA sequencing conformed that the heterological PSCA fusion antigen fragment which was synchronized by overlapping-extending-PCR,was consistent to design.Enzyme digestion analysis showed that the 1 to 4 copies heterological PSCA fusion antigen fragments were constructed successfully.
