Gaia Focused Product Release: Asteroid orbital solution: Properties and assessment
Stephan Morgenthaler, Shuangqing Liao
Context. We report the exploitation of a sample of Solar System observations based on data from the third Gaia Data Release (Gaia DR3) of nearly 157 000 asteroids. It extends the epoch astrometric solution over the time coverage planned for the Gaia DR4, w ...
Les Ulis Cedex A2023Positive Definite Completions and Continuous Graphical Models
This thesis concerns the theory of positive-definite completions and its mutually beneficial connections to the statistics of function-valued or continuously-indexed random processes, better known as functional data analysis. In particular, it dwells upon ...
EPFL2023Microgravity induces overconfidence in perceptual decision-making
Davide Scaramuzza, Christian Pfeiffer, Leyla Loued-Khenissi
Does gravity affect decision-making? This question comes into sharp focus as plans for interplanetary human space missions solidify. In the framework of Bayesian brain theories, gravity encapsulates a strong prior, anchoring agents to a reference frame via ...
NATURE PORTFOLIO2023Processing load, and not stimulus evidence, determines the duration of unconscious visual feature integration
Michael Herzog, Leila Drissi Daoudi - Kleinbauer, Lukas Vogelsang
Integration across space and time is essential for the analysis of motion, low contrast, and many more stimuli. A crucial question is what determines the duration of integration. Based on classical models of decision-making, one might expect that integrati ...
2023A simple theoretical model for estimating the frequency characteristics of black hole mergers
Gravitational waves, despite predicted within the Theory of General Relativity about a century ago, were observed experi-mentally only in the last few years, thanks to the recent advances of the LIGO and Virgo detectors. In this work, we introduce a simple ...
CANADIAN SCIENCE PUBLISHING2022The eta Aquilae System: Radial Velocities and Astrometry in Search of eta Aql B
The classical Cepheid eta Aql was not included in past Leavitt Law work because of a presumed complicating orbit due to a known B9.8V companion. To determine the orbit of eta Aql B, we analyze a significant number of radial velocity (RV) measurements from ...
2022The long cross-over dynamics of capillary imbibition
Spontaneous capillary imbibition is a classical problem in interfacial fluid dynamics with a broad range of applications, from microfluidics to agriculture. Here we study the duration of the cross-over between an initial linear growth of the imbibition fro ...
CAMBRIDGE UNIV PRESS2022An automatized signal timing detection at signalized intersections with detailed vehicle trajectory data
Nikolaos Geroliminis, Emmanouil Barmpounakis, Jasso Espadaler Clapés
Signalized intersections are a fundamental part of urban networks. Their understanding is crucial to identify congestion patterns, queues, delays, and safety issues in local and network level. In this work, we analyze multimodal vehicle trajectories and pr ...
2022Many-Body Self-Interaction and Polarons
Alfredo Pasquarello, Stefano Falletta
We address the many-body self-interaction in relation to polarons in density functional theory. Our study provides (i) a unified theoretical framework encompassing many-body and one-body forms of self-interaction and (ii) an efficient semilocal scheme for ...
2022Roadmap on Machine learning in electronic structure
Michele Ceriotti, Jigyasa Nigam, Andrea Grisafi, Max David Veit
In recent years, we have been witnessing a paradigm shift in computational materials science. In fact, traditional methods, mostly developed in the second half of the XXth century, are being complemented, extended, and sometimes even completely replaced by ...
