A VLBI Study of the Gravitational Lens JVAS B0218+357
R. Mittal, R. Porcas, O. Wucknitz +1
We present the results of phase-referenced VLBA+Effelsberg observations at five frequencies of the gravitational lens B0218+357 to establish the precise registration of the A and B…
Poincare recurrence and measure of hyperbolic and nonhyperbolic chaotic attractors
Murilo S. Baptista, Suso Kraut, Celso Grebogi
We study Poincare recurrence of chaotic attractors for regions of finite size. Contrary to the standard case, where the size of the recurrent regions tends to zero, the measure is…
Classical information capacity of a class of quantum channels
M. M. Wolf, J. Eisert
We consider the additivity of the minimal output entropy and the classical information capacity of a class of quantum channels. For this class of channels the norm of the output is…
Origin of temperature dependent conductivity of -polyvinylidene fluoride
Enis Tuncer, Michael Wegener, Peter Frübing +1
The conductivity of -polyvinylidene fluoride (-PVDF) is obtained from dielectric measurements performed in the frequency domain at several temperatures. At temperatures above…
Elastic properties of highly anisotropic thin poly(propylene) foams
Enis Tuncer, Michael Wegener
In this letter, elastic properties of highly anisotropic cellular poly(propylene) films are reported. The material shows peculiar elastic properties compared to other foams in the…
Phenomenology of brane-world cosmological models
Uwe Guenther, Alexander Zhuk
We present a brief review of brane-world models - models in which our observable Universe with its standard matter fields is assumed as localized on a domain wall (three-brane) in…
