Recent developments in Laue lens manufacturing and their impact on imaging performance
Lisa Ferro, Enrico Virgilli, Natalia Auricchio +9
We report on recent progress in the development of Laue lenses for applications in hard X/soft gamma-ray astronomy. Here we focus on the realization of a sector of such a lens made…
How to Evaluate your Question Answering System Every Day and Still Get Real Work Done
Eric Breck, John D. Burger, Lisa Ferro +4
In this paper, we report on Qaviar, an experimental automated evaluation system for question answering applications. The goal of our research was to find an automatically calculate…
An advanced pulse-avalanche stochastic model of long gamma-ray burst light curves
Manuele Maistrello, Lisa Ferro, Lorenzo Bazzanini +2
A unified explanation of the variety of long-duration gamma-ray burst (GRB) light curves (LCs) is essential for identifying the dissipation mechanism and possibly the nature of the…
Opening the path to hard X-/soft gamma-ray focussing: the ASTENA-pathfinder mission
Enrico Virgilli, Lorenzo Amati, Natalia Auricchio +10
Hard X-/soft gamma-ray astronomy is a crucial field for transient, nuclear and multimessenger astrophysics. However, the spatial localization, imaging capabilities and sensitivity…
Imaging performance above 150 keV of the wide field monitor on board the ASTENA concept mission
Lisa Ferro, Leo Cavazzini, Miguel Moita +10
A new detection system for X-/Gamma-ray broad energy passband detectors for astronomy has been developed. This system is based on Silicon Drift Detectors (SDDs) coupled with scinti…
Learning Transformation Rules to Find Grammatical Relations
Lisa Ferro, Marc Vilain, Alexander Yeh
Grammatical relationships are an important level of natural language processing. We present a trainable approach to find these relationships through transformation sequences and er…
The TRILL project: increasing the technological readiness of Laue lenses
Lisa Ferro, Enrico Virgilli, Miguel Moita +16
Hard X-/soft Gamma-ray astronomy (> 100 keV) is a crucial field for the study of important astrophysical phenomena such as the 511 keV positron annihilation line in the Galactic ce…
Long gamma-ray burst light curves as the result of a common stochastic pulse-avalanche process
Lorenzo Bazzanini, Lisa Ferro, Cristiano Guidorzi +9
Context. The complexity and variety exhibited by the light curves of long gamma-ray bursts (GRBs) enclose a wealth of information that still awaits being fully deciphered. Despite…
