Ni K-edge x-ray-absorption spectroscopy ~XAS! measurements on a series of perovskite-layer-based nickelate compounds, with varying formal Ni valence, are presented. Spectral features that vary systematically with the Ni configuration are identified for these Ruddlesden-Popper phase and Sr substituted Ln22xSrxNiO4 ~Ln5La and Nd! materials. Selected polarized… (More)
We try to determine the type of abdominal pain of the patients who have several symptoms. Via the rough set theory, we obtain information table and discernibility matrix and put forward the status decision information. Thus, we obtain certain results and test these operations by the Rosetta program.
Motivated by surface x-ray scattering experiments on homoepitaxially grown Ag(001), scattering models for surfaces having submonolayer coverages are discussed in the context of small angle scattering. It is shown that the surface diffuse line shapes can be interpreted in terms of intraisland and inter-island scattering. The connection between these models… (More)
