Local ensemble transform Kalman filter, a fast non-stationary control law for adaptive optics on ELTs: theoretical aspects and first simulation results
Morgan Gray, Cyril Petit, Sergey Rodionov +4
We propose a new algorithm for an adaptive optics system control law, based on the Linear Quadratic Gaussian approach and a Kalman Filter adaptation with localizations. It allows t…
Fast Computation of Solvation Free Energies with Molecular Density Functional Theory: Thermodynamic-Ensemble Partial Molar Volume Corrections
Volodymyr P. Sergiievskyi, Guillaume Jeanmairet, Maximilien Levesque +1
Molecular Density Functional Theory (MDFT) offers an efficient implicit- solvent method to estimate molecule solvation free-energies whereas conserving a fully molecular representa…
Age, size, and position of H ii regions in the Galaxy. Expansion of ionized gas in turbulent molecular clouds
P. Tremblin, L. D. Anderson, P. Didelon +8
This work aims at improving the current understanding of the interaction between H ii regions and turbulent molecular clouds. We propose a new method to determine the age of a larg…
Understanding star formation in molecular clouds II. Signatures of gravitational collapse of IRDCs
N. Schneider, T. Csengeri, R. S. Klessen +6
We analyse column density and temperature maps derived from Herschel dust continuum observations of a sample of massive infrared dark clouds (G11.11-0.12, G18.82-0.28, G28.37+0.07,…
A consistent deterministic regression tree for non-parametric prediction of time series
Pierre Gaillard, Paul Baudin
We study online prediction of bounded stationary ergodic processes. To do so, we consider the setting of prediction of individual sequences and build a deterministic regression tre…
Understanding star formation in molecular clouds I. Effects of line-of-sight contamination on the column density structure
N. Schneider, V. Ossenkopf, T. Csengeri +6
Column-density maps of molecular clouds are one of the most important observables in the context of molecular cloud- and star-formation (SF) studies. With the Herschel satellite it…
