This paper investigates regional inequality in a multi-scale framework, using Exploratory Spatial Data Analysis, based on the per capita Gross Domestic Product (GDP) of counties and municipalities within the Zhejiang province in China between the years of 1990 and 2010. A Spatial Markov Chain is used to identify the dynamics of regional wealth disparity in(More)
We have observed dynamical diffraction in the [[(02402̅ 4) and [[(04604̅ 6) reflections of the icosahedral quasicrystal AlPdMn in the back-reflection geometry ( θB = 90°). The x-ray fluorescence from the Al and Pd atoms exhibits strong standing wave behavior, similar to that observed in crystalline materials. The data indicate a long-range order of each(More)
