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

Secular orbital evolution of Jupiter family comets
, 2017 Context. The issue of the long term dynamics of Jupiter family comets (JFCs) involves uncertain assumptions about the physical evolution and lifetimes of these comets. Contrary to what is often assumed, real effects of secular dynamics cannot be excluded

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.

Formation and Migration of Trans-Neptunian Objects - Proceedings of the conference "Scientific Frontiers in Research of Extrasolar Planets" [PDF]
ASP Conf.Ser.294:349-353,2003, 2002 Some large trans-Neptunian objects could be formed by the compression of rarefied dust condensations, but not by the accumulation of smaller planetesimals. A considerable portion of near-Earth objects could have come from the trans-Neptunian region. Our runs of the evolution of thousands orbits of Jupiter-family comets under the gravitational influence

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

Performance Analysis of Skip-Glide Trajectories for Hypersonic Waveriders in Planetary Exploration [PDF]
, 2008 A performance analysis for skip and glide is being studied to investigate the potential usage of waverider technology for interplanetary explorations. While the skip and glide equations themselves were first explored by Eggers, this thesis will implement
