The Shell Corrections And Shell Gaps In Nuclei Are Systematically Studied With The Latest Weizsacker-skyrme (Ws4) Mass Model. We Find That Most Of Asymmetric Nuclei With (Sub) Shell Closures Locate Along The Shell Stability Line (Ssl) n=1.37z+13.5 Which Might Be Due To a Strong Correlation Between Neutrons And proTons Near The Fermi Surface. The Double Magicity Of Nuclei Si-46 And Ni-78 Is Predicted According To The Corresponding Shell Gaps Shell Corrections And Nuclear Deformations. The Unmeasured Superheavy Nuclei (296)118 And (298)120 With Relatively Large Shell Gaps And Shell Corrections Also Locate Along The Ssl Whereas The Traditional Magic Nucleus (298)F1 Evidently Deviates From The Line. The Alpha-decay Energies Of Superheavy Nuclei With Z=113-126 Are Simultaneously Investigated By Using The Ws4 Model togeTher With The Radial Basis Function Corrections. For Superheavy Nuclei With Large Shell Corrections The Smallest Alpha-decay Energy For Elements Z=116 117 And 118 In Their Isotope chaIns LocAtes At N=178 rAther Than 184.

There exist complex gray mapping relationships among infrared and visible images because of the different imaging mechanisms. The difficulty of infrared and visible image registration is to find a reasonable similarity definition. In this paper, we develop a novel image similarity called implicit linesegment similarity(ILS) and a registration algorithm of infrared and visible images based on ILS. Essentially, the algorithm achieves image registration by aligning the corresponding line segment features in two images. First, we extract line segment features and record their coordinate positions in one of the images, and map these line segments into the second image based on the geometric transformation model. Then we iteratively maximize the degree of similarity between the line segment features and correspondence regions in the second image to obtain the model parameters. The advantage of doing this is no need directly measuring the gray similarity between the two images. We adopt a multi-resolution analysis method to calculate the model parameters from coarse to fine on Gaussian scale space. The geometric transformation parameters are finally obtained by the improved Powell algorithm. Comparative experiments demonstrate that the proposed algorithm can effectively achieve the automatic registration for infrared and visible images, and under considerable accuracy it makes a more significant improvement on computational efficiency and anti-noise ability than previously proposed algorithms.
