Systematic Numerical Study of the Propagation of Monochromatic Radiation through a Stationary Atmosphere in a Model of Plane Plane-Parallel Layers

N. Antonietti, M. Mondin, G. Catastini +2

In this paper, the authors compare the security bounds for different quantum communication protocols with the numerically evaluated losses in the transmission channel, due to the i…

Asymptotic Mutual Information Statistics of Separately-Correlated Rician Fading MIMO Channels

Giorgio Taricco

Precise characterization of the mutual information of MIMO systems is required to assess the throughput of wireless communication channels in the presence of Rician fading and spat…

Higher-order gravity and the cosmological background of gravitational waves

S. Capozziello, M. De Laurentis, M. Francaviglia

The cosmological background of gravitational waves can be tuned by the higher-order corrections to the gravitational Lagrangian. In particular, it can be shown that assuming $R^{1+…

Gauged Supergravities from Twisted Doubled Tori and Non-Geometric String Backgrounds

Gianguido Dall'Agata, Nikolaos Prezas, Henning Samtleben +1

We propose a universal geometric formulation of gauged supergravity in terms of a twisted doubled torus. We focus on string theory (M-theory) reductions with generalized Scherk-Sch…

Distributed Arithmetic Coding for the Asymmetric Slepian-Wolf problem

M. Grangetto, E. Magli, G. Olmo

Distributed source coding schemes are typically based on the use of channels codes as source codes. In this paper we propose a new paradigm, termed "distributed arithmetic coding",…

Spatial signal amplification in cell biology: a lattice-gas model for self-tuned phase ordering

Teresa Ferraro, Antonio de Candia, Andrea Gamba +1

Experiments show that the movement of eukaryotic cells is regulated by a process of phase separation of two competing enzymes on the cell membrane, that effectively amplifies shall…
