Model-Free Local Recalibration of Neural Networks
R. Torres, D. J. Nott, S. A. Sisson +3
Artificial neural networks (ANNs) are highly flexible predictive models. However, reliably quantifying uncertainty for their predictions is a continuing challenge. There has been m…
Free-floating planetary mass objects in LDN 1495 from Euclid Early Release Observations
H. Bouy, E. L. MartÃn, J. -C. Cuillandre +8
Context. Substellar objects, including brown dwarfs and free-floating planetary-mass objects, are a significant product of star formation. Their sensitivity to initial conditions a…
Pyramid quantile regression
T. Rodrigues, J. -L. Dortet-Bernadet, Y. Fan
Quantile regression models provide a wide picture of the conditional distributions of the response variable by capturing the effect of the covariates at different quantile levels.…
Noncrossing simultaneous Bayesian quantile curve fitting
T. Rodrigues, J. -L. Dortet-Bernadet, Y. Fan
Bayesian simultaneous estimation of nonparametric quantile curves is a challenging problem, requiring a flexible and robust data model whilst satisfying the monotonicity or noncros…
Borderline hyperbolic comet C/2021 O3 (PANSTARRS) was fading as it approached the Sun
M. Evangelista-Santana, M. De Prá, J. M. Carvano +13
We present an observational and numerical study of the borderline hyperbolic comet C/2021 O3 (PANSTARRS) performed during its recent passage through the inner Solar system. Our obs…
Pressure shifts in pulsatile shear: A microfluidic method to probe the normal stress response of complex fluids
T. Rodrigues, F. J. Galindo-Rosales, L. Campo-Deaño
A microfluidic approach to probing the first normal stress difference from single-point pressure measurements in transient shear flows is presented. Using an original experimental…
Scaling slowly rotating asteroids by stellar occultations
A. Marciniak, J. Äurech, A. Choukroun +176
As evidenced by recent survey results, majority of asteroids are slow rotators (P>12 h), but lack spin and shape models due to selection bias. This bias is skewing our overall unde…
Properties of slowly rotating asteroids from the Convex Inversion Thermophysical Model
A. Marciniak, J. Äurech, V. AlÃ-Lagoa +73
Results from the TESS mission showed that previous studies strngly underestimated the number of slow rotators, revealing the importance of studying those asteroids. For most slowly…
The CoRoT-GES Collaboration. Improving Red Giants spectroscopic surface gravity and abundances with asteroseismology
M. Valentini, C. Chiappini, A. Miglio +4
Nowadays large spectroscopic surveys, like the Gaia-ESO Survey (GES), provide unique stellar databases for better investigating the formation and evolution of our Galaxy. Great att…
Positional Encoder Graph Quantile Neural Networks for Geographic Data
William E. R. de Amorim, Scott A. Sisson, T. Rodrigues +2
Positional Encoder Graph Neural Networks (PE-GNNs) are among the most effective models for learning from continuous spatial data. However, their predictive distributions are often…
On flow disturbances caused by pressure taps in highly elastic flows around a microfluidic cylinder
R. Rodrigues, T. Rodrigues, L. Campo-Deaño
The objective of this work is to characterise the onset of laterally asymmetric flow of viscoelastic solutions around a confined microfluidic cylinder, which was encountered in a r…
A class of cubic Rauzy Fractals
J. Bastos, A. Messaoudi, D. Smania +1
In this paper, we study arithmetical and topological properties for a class of Rauzy fractals given by the polynomial where is an intege…
PLATO as it is: a legacy mission for Galactic archaeology
A. Miglio, C. Chiappini, B. Mosser +102
Deciphering the assembly history of the Milky Way is a formidable task, which becomes possible only if one can produce high-resolution chrono-chemo-kinematical maps of the Galaxy.…
RAVE stars in K2 - I. Improving RAVE red giants spectroscopy using asteroseismology from K2 Campaign 1
M. Valentini, C. Chiappini, G. R. Davies +29
We present a set of 87 RAVE stars with detected solar like oscillations, observed during Campaign 1 of the K2 mission (RAVE K2-C1 sample). This dataset provides a useful benchmark…
