Constraints on Clumps in the Representative Wind of the WN8 Wolf-Rayet star HD96548 = WR40 with Simultaneous Broadband Light and Linear-Polarisation Variability
Richard Ignace, Anthony Moffat, Carmelle Robert +1
We report precision ground-based broadband optical intensity and linear-polarisation light-curves for the sky's brightest WN8 star, WR40. WN8 stars are notorious for their high lev…
The determining role of covariances in large networks of stochastic neurons
Vincent Painchaud, Patrick Desrosiers, Nicolas Doyon
Biological neural networks are notoriously hard to model due to their stochastic behavior and high dimensionality. We tackle this problem by constructing a dynamical model of both…
Vacuum Decay Actions from Tunneling Potentials for General Spacetime Dimension
J. R. Espinosa, J. -F. Fortin
The tunneling potential method to calculate the action for vacuum decay is an alternative to the Euclidean bounce method that has a number of attractive features. In this paper we…
Understanding the role of morphology and environment on the dynamical evolution of isolated galaxy triplets
P. Vásquez-Bustos, M. Argudo-Fernández, D. Grajales-Medina +2
The environment where galaxies reside affects their evolutionary histories. Galaxy triplets (systems composed of three physically bound galaxies) constitute one of simplest group o…
Optimized Spectral Energy Distribution for Seyfert Galaxies
Luc Binette, Yair Krongold, Sinhue A. R. Haro-Corzo +2
The temperature predicted by photoionization models for the Narrow Line Region of Seyfert 2 galaxies is lower than the value inferred from the observed [O III] λ4363A/λ5007A line r…
Tree Detection and Diameter Estimation Based on Deep Learning
Vincent Grondin, Jean-Michel Fortin, François Pomerleau +1
Tree perception is an essential building block toward autonomous forestry operations. Current developments generally consider input data from lidar sensors to solve forest navigati…
Forming Stars in a Dual AGN Host: Molecular and Ionized Gas in the Nearby, Luminous Infrared Merger, Mrk 266
Damien Beaulieu, Andreea Petric, Carmelle Robert +5
We present star formation rates based on cold and ionized gas measurements of Mrk 266 (NGC 5256), a system composed of two colliding gas-rich galaxies, each hosting an active galac…
GSV-Cities: Toward Appropriate Supervised Visual Place Recognition
Amar Ali-bey, Brahim Chaib-draa, Philippe Giguère
This paper aims to investigate representation learning for large scale visual place recognition, which consists of determining the location depicted in a query image by referring t…
Calibration-based abundances in the interstellar gas of galaxies from slit and IFU spectra
Pilyugin L. S., Lara-Lopez M. A., Vilchez J. M. +3
In this work we make use of available Integral Field Unit (IFU) spectroscopy and slit spectra of several nearby galaxies. The pre-existing empirical R and S calibrations for abunda…
SIT 45: An interacting, compact, and star-forming isolated galaxy triplet
D. Grajales-Medina, M. Argudo-Fernández, P. Vásquez-Bustos +7
The merging system SIT 45 (UGC 12589) is an unusual isolated galaxy triplet, consisting of three merging late-type galaxies, out of 315 systems in the SIT (SDSS-based catalogue of…
Strong Field Non-Franck-Condon Ionization of H: A Semi-Classical Analysis
Jean-Nicolas Vigneau, O. Atabek, Thanh-Tung Nguyen-Dang +1
Single ionization of H molecules exposed to strong and short laser pulses is investigated by a semi-classical method. Three laser characteristics are considered: i) The carrier…
Strong-Field Molecular Ionization Beyond The Single Active Electron Approximation
Jean-Nicolas Vigneau, Tung Nguyen-Dang, Eric Charron +1
The present work explores quantitative limits to the Single-Active Electron (SAE) approximation, often used to deal with strong-field ionization and subsequent attosecond dynamics.…
Fast Metasurface Hybrid Lens Design using a Semi-Analytical Model
Alexandre Cléroux Cuillerier, Jeck Borne, Simon Thibault
We propose a new method for integrating metasurfaces in optical design using semi-analytical modelling of dielectric nanostructures. The latter computes the output phase of an elec…
Understanding Interventional TreeSHAP : How and Why it Works
Gabriel Laberge, Yann Pequignot
Shapley values are ubiquitous in interpretable Machine Learning due to their strong theoretical background and efficient implementation in the SHAP library. Computing these values…
Reduced Density Matrices / Static Correlation Functions of Richardson-Gaudin States Without Rapidities
Alexandre Faribault, Claude Dimo, Jean-David Moisset +1
Seniority-zero geminal wavefunctions are known to capture bond-breaking correlation. Among this class of wavefunctions, Richardson-Gaudin states stand out as they are eigenvectors…
A preprocessing perspective for quantum machine learning classification advantage using NISQ algorithms
Javier Mancilla, Christophe Pere
Quantum Machine Learning (QML) hasn't yet demonstrated extensively and clearly its advantages compared to the classical machine learning approach. So far, there are only specific c…
Quantifying French Document Complexity
Vincent Primpied, David Beauchemin, Richard Khoury
Measuring a document's complexity level is an open challenge, particularly when one is working on a diverse corpus of documents rather than comparing several documents on a similar…
Hypergraph reconstruction from noisy pairwise observations
Ariane Lizotte, Jean-Gabriel Young, Antoine Allard
The network reconstruction task aims to estimate a complex system's structure from various data sources such as time series, snapshots, or interaction counts. Recent work has exami…
Fragmented atomic shell around S187 HII region and its interaction with molecular and ionized gas
