We describe spatial patterns in environmental injustice and inequality for residential outdoor nitrogen dioxide (NO2) concentrations in the contiguous United States. Our approach employs Census demographic data and a recently published high-resolution dataset of outdoor NO2 concentrations. Nationally, population-weighted mean NO2 concentrations are 4.6 ppb (38%, p<0.01) higher for nonwhites tha...
Th is paper analyses the nature and causes of the patterns of inequality and poverty in India. Since the economic liberalization in the early 1990s, the evidence suggests increasing inequality (in both spatial and vertical terms) as well as persistent poverty.

The article is devoted to the problem of spatial inequality regions caused by centripetal or centrifugal forces because agglomeration effects and interaction costs. It corresponds with main idea new economic geography. A differentiated approach regional development strategizing proposed in study as a tool for reducing level imbalance. Herein use technological arbitrage (catching-up) strategy pe...
The Cauchy-Schwarz (CS) inequality-one of the most widely used and important inequalities in mathematics-can be formulated as an upper bound to the strength of correlations between classically fluctuating quantities. Quantum-mechanical correlations can, however, exceed classical bounds. Here we realize four-wave mixing of atomic matter waves using colliding Bose-Einstein condensates, and demons...
