Blazars in hard X-rays astro-ph.CO astro-ph.HE Although blazars are thought to emit most of their luminosity in the gamma-ray band, there are subclasses of them very prominent in hard X-rays. These are the best candidates to be studied by Simbol-X. They are at the extremes of the blazar sequence, having very small ...

The Strange Prospects for Astrophysics astro-ph.HE nucl-th The implications of the formation of strange quark matter in neutron stars and in core-collapse supernovae is discussed with special emphasis on the possibility of having a strong first order QCD phase transition at high baryon densities. If strange quark m...

Conventions spreading in open-ended systems physics.soc-ph We introduce a simple open-ended model that describes the emergence of a shared vocabulary. The ordering transition toward consensus is generated only by an agreement mechanism. This interaction defines a finite and small number of states, despite each indi...

Electronic Refrigeration at the Quantum Limit cond-mat.mes-hall cond-mat.supr-con We demonstrate quantum limited electronic refrigeration of a metallic island in a low temperature micro-circuit. We show that matching the impedance of the circuit enables refrigeration at a distance, of about 50 um in our case, throu...
