Sum rules and physical bounds on passive metamaterials

Frequency dependence of the permittivity and permeability is inevitable in metamaterial applications such as cloaking and perfect lenses. In this paper, Herglotz functions are used as a tool to construct sum rules from which we derive physical bounds suited for metamaterial applications, where the material parameters are often designed to be negative or near zero in the frequency band of interest.

Explicit local exchange-correlation potentials

The possibilities of the Hohenberg-Kohn-Sham local density theory are explored in view of recent advances in the theory of the interacting electron gas. The authors discuss and provide numerical data for the effective exchange-correlation potentials μxc for ground state problems and Vxc for excitation spectra. The potential μxc(r) is written as a factor β(ρ(r)), which depends on the local density

Subcellular localization of transforming growth factor-alpha in human eosinophil granulocytes

Eosinophils are involved in the inflammatory response seen in allergy and helminthic infestations. Eosinophils synthesize transforming growth factor-alpha (TGF-alpha), which may play a role in the development of the characteristic fibrosis seen in longstanding high eosinophilia. Using immunoelectron microscopic techniques, eosinophils from peripheral blood of healthy individuals and from one patie

Methods for Assessing Traffic Safety in Developing Countries

Every year about 15 million people are injured in traffic, 500,000 of these fatally. Developing countries are badly affected. During the worst years of the war in Nicaragua, more people died in traffic accidents than as a direct result of the war. Transport system and infrastructure have developed rapidly in developing countries, while little has been achieved in preventing accidents or lessening

Correlation-based phase synthesis approach for MIMO capacity prediction using antenna magnitude patterns

This paper concerns the estimation of MIMO capacity in a given propagation environment from the magnitude patterns of multiple antennas. In our previous contribution, we presented a simple approach of synthesizing phase on the magnitude patterns by taken into account the antenna separation. Although this approach works well even when the antenna separation is small and the signal correlation is hi
