HIFLUGCS: Galaxy cluster scaling relations between X-ray luminosity, gas mass, cluster radius, and velocity dispersion
Y. -Y. Zhang, H. Andernach, C. A. Caretta +5
We present relations between X-ray luminosity and velocity dispersion (L-sigma), X-ray luminosity and gas mass (L-Mgas), and cluster radius and velocity dispersion (r500-sigma) for…
Adsorption of molecular gases on porous materials in the SAFT-VR approximation

We present a Spitzer IRS study of variability in 14 T Tauri stars in the Taurus and Chamaeleon star-forming regions. The sample is composed of transitional and pre-transitional obj…
Photonic density of states maps for design of photonic crystal devices
I. A. Sukhoivanov, I. V. Guryev, J. A. Andrade Lucio +3
In this work, it has been investigated whether photonic density of states maps can be applied to the design of photonic crystal-based devices. For this reason, comparison between p…

We propose a new method for mass production of the photonic crystal devices on the basis of widely-known and well-developed technology such as microstructured optical fibers. In th…
Reply to "Avoiding the Detector Blinding Attack on Quantum Cryptography"
Lars Lydersen, Carlos Wiechers, Christoffer Wittmann +3
This is a reply to the comment by Yuan et al. [arXiv:1009.6130v1] on our publication [arXiv:1008.4593].
Near-Horizon geometry from flux compactification
Oscar Loaiza-Brito, Liliana Vazquez-Mercado
We study the conditions an arbitrary flux configuration must fulfill in order to construct a 4d space-time of the type from a type IIB supergravity flux compactif…
Relation between activity, morphology and environment for a large sample of SDSS galaxies
R. A. Ortega-Minakata, J. P. Torres-Papaqui, H. Andernach +2
We apply a stellar population synthesis code to the spectra of a large sample of SDSS galaxies to classify these according to their activity (using emission-line diagnostic diagram…
Z'-> ggg decay in left-right symmetric models with three and four fermion families
J. Montano, M. Napsuciale, C. A. Vaquera-Araujo
We study the Z'-> ggg decay in the context of a left-right symmetric gauge theory. We obtain a branching ratio BR(Z'-> ggg)=Γ(Z'->ggg)/ Γ(Z'-> q\bar{q})= (1.2-2.8) x 10^{-5} for m_…

In this work we consider a flat cosmological model with a set of fluids in the framework of supersymmetric cosmology. The obtained supersymmetric algebra allowed us to take quantum…
Can noncommutative effects account for the present speed up of the cosmic expansion?
Octavio Obregon, Israel Quiros
In this paper we investigate to which extent noncommutativity, a intrinsically quantum property, may influence the Friedmann-Robertson-Walker cosmological dynamics at late times/la…
