Sparse Randomized Shortest Paths Routing with Tsallis Divergence Regularization

Pierre Leleux, Sylvain Courtain, Guillaume Guex +1

This work elaborates on the important problem of (1) designing optimal randomized routing policies for reaching a target node t from a source note s on a weighted directed graph G…

Randomized Shortest Paths with Net Flows and Capacity Constraints

Sylvain Courtain, Pierre Leleux, Ilkka Kivimaki +2

This work extends the randomized shortest paths (RSP) model by investigating the net flow RSP and adding capacity constraints on edge flows. The standard RSP is a model of movement…

Indirect study of 19Ne states near the 18F+p threshold

N. de Sereville, A. Coc, C. Angulo +22

The early E < 511 keV gamma-ray emission from novae depends critically on the 18F(p,a)15O reaction. Unfortunately the reaction rate of the 18F(p,a)15O reaction is still largely unc…

SPI/INTEGRAL observation of the Cygnus region

L. Bouchet, E. Jourdain, J. -P. Roques +22

We present the analysis of the first observations of the Cygnus region by the SPI spectrometer onboard the Integral Gamma Ray Observatory, encompassing 600 ks of data. Thr…

INTEGRAL/SPI ground calibration

D. Attié, B. Cordier, M. Gros +30

Three calibration campaigns of the spectrometer SPI have been performed before launch in order to determine the instrument characteristics, such as the effective detection area, th…
