We are presented of several basic properties for negatively superadditive dependent(NSD) random variables. By using this concept we are obtained complete convergence for maximum partial sums of rowwise NSD random variables. These results obtained in this paper generalize a corresponding ones for independent random variables and negatively associated random variables.

We investigate the tensile stretching behaviors of copper (Cu) nanowires (NWs) containing various vacancy defects using the embedded-atom molecular dynamics modeling approach. The coupled effects in various shapes, sizes, and locations of vacancy clusters (VC) and wire cross-sectional area on the mechanical strength and structural deformation of NWs are presented. The formation energies of VC defects are also evaluated. As the location of cluster defects changed from the edges to the surface or inside of wires, the yield strength decreased. Moreover, as the cluster shape changed from octahedron to cuboctahedron, the yield strength also substantially decreased. The extraordinarily structural evolution of defective wires that precede wire fracture from 10/4 transient multi-shell (TMS) structures necking into 1/5-type pentagonal rings were also identified via the analyses of potential energy, local stress, and atomistic number density.

Colleges of technology in Japan are characterized by specialized education starting from the first grades aged fifteen, making it particularly important to provide motivation for specialized subjects. The most difficult thing for teachers in the technical college is giving the motivation to a professional education to the lower grades who don t know the technology and engineering. Teachers tried to use and make a suitable example or an education material for their lecture. The generation gap with students makes it difficult for teachers to use examples of objects that students are actually familiar with in their daily life. To compensate for the generation gap with students, we asserted that education for lower grades should adopt the perspectives of students in higher grades. The relative closeness in age of lower and higher grades helps reduce the generation gap with students, which is advantageous in that teachers can share the perspectives of students.
