Energy Minimization for the Half-Duplex Relay Channel with Decode-Forward Relaying

, 2013
We analyze coding for energy efficiency in relay channels at a fixed source rate. We first propose a half-duplex decode-forward coding scheme for the Gaussian relay channel.

Angular distribution of cosmic rays from an individual source in a turbulent magnetic field [PDF]

, 2016
We obtain the angular distribution of the cosmic rays reaching an observer from an individual source and after propagation through a turbulent magnetic field, for different ratios between the source distance and the diffusion length.

Observation of TeV gamma-rays from the unidentified source HESS J1841-055 with the ARGO-YBJ experiment [PDF]

, 2013
We report the observation of a very high energy \gamma-ray source, whose position is coincident with HESS J1841-055. This source has been observed for 4.5 years by the ARGO-YBJ experiment from November 2007 to July 2012.

Centaurus A at Ultra-High Energies [PDF]

, 2010
We review the importance of Centaurus A in high energy astrophysics as a nearby object with many of the properties expected of a major source of very high energy cosmic rays and gamma-rays.

A new approach to electromagnetic wave tails on a curved spacetime

, 2000
We present an alternative method for constructing the exact and approximate solutions of electromagnetic wave equations whose source terms are arbitrary order multipoles on a curved spacetime.
