Supergravity pp-wave solutions with 28 and 24 supercharges
We conduct an exhaustive search for solutions of IIA and IIB supergravity with augmented supersymmetry. We find a two-parameter family of IIB solutions preserving 28 supercharges, as well as several other IIA and IIB families of solutions with 24 supercharges. Given the simplicity of the pp-wave solution, the algorithm described here represents a systematic way of classifying all such solutions...

[12] W. F. Punch, et al, " A genetic algorithm approach to design of advanced composite material structures " , MSU Reference paper, 1993. 18 coded into the genome. A branch-and-bound method was considered, but rejected as too expensive. Also, a left-to-right march was considered. Perhaps one of these approaches are actually worth attempting. Different parallel structures could be attempted. As...
متن کاملThe Supercharges of Eleven-dimensional Supergraviton on Gravitational Wave Background
We find the explicit expression of the supercharges of eleven dimensional supergraviton on the background geometry of gravitational waves in asymptotically light-like compactified spacetime. We perform the calculations order by order in the fermions ψ, while retaining all orders in bosonic degrees of freedom, and get the closed form up to ψ order. This should correspond to the supercharge of th...

26 THE DIAPASON This article celebrates the 100th anniversary of Distler’s birth year. It enhances understanding of Distler as a composer and examines performance aspects of his organ works. Relevant biographical information introduces us to Distler’s socio-historical environment. The physical infl uences of Lübeck’s organs and Distler’s house organ explain Distler’s compositional output in ter...

Recently, secondary school students have been required to have Internet literacy for their school life and study. However, the parents of the students do not want their children to be addicted to the Internet and smart phones due to the heavy use of their devices. In this paper, we analyze the relationship between Internet literacy and the Internet and smart phone addictions with secondary scho...
