ROCKET: Robust Confidence Intervals via Kendall's Tau for Transelliptical Graphical Models [PDF]
arXiv, 2015 Undirected graphical models are used extensively in the biological and social sciences to encode a pattern of conditional independences between variables, where the absence of an edge between two nodes $a$ and $b$ indicates that the corresponding two variables $X_a$ and $X_b$ are believed to be conditionally independent, after controlling for all other

Dynamical evolution and end states of active and inactive Centaurs [PDF]
, 2018 We numerically study the dynamical evolution of observed samples of active and inactive Centaurs and clones that reach the Jupiter-Saturn region. Our aim is to compare the evolution between active and inactive Centaurs, their end states and their transfer to Jupiter family comets and Halley-type comets.

SPICA infrared coronagraph for the direct observation of exo-planets
, 2010 We present a MIR coronagraph to target the direct observation of extrasolar planets for SPICA, in which a coronagraph is currently regarded as an option of the focal plane instruments. The primary target of the SPICA coronagraph is the direct observation
