A fibered laser system for the MIGA large scale atom interferometer

open access: yesScientific Reports, 2020
We describe the realization and characterization of a compact, autonomous fiber laser system that produces the optical frequencies required for laser cooling, trapping, manipulation, and detection of 87Rb atoms - a typical atomic species for emerging ...

Extending the Range of Sizes of Monodisperse Core‐Shell Hydrogel Capsules from Composite Jet Breakup by Combined Electrical and Mechanical Actuation

open access: yesAdvanced Science
The production of monodisperse particles or droplets is a longstanding issue across various fields, from aerosol science to inkjet printing. In bioengineering, sub‐millimeter cell‐laden hydrogel capsules have proven valuable for developing in vitro ...

Alkene Hydrogenation by a Cationic, Nine‐Coordinate Molybdenum(VI) Pentahydride Catalyst

open access: yesChemistry – A European Journal, EarlyView.
While late 3d metals dominate efforts to replace precious metals in homogeneous hydrogenation, molybdenum has remained largely ignored. This work reveals that a nine‐coordinate pentahydrido molybdenum complex can hydrogenate a broad range of alkenes efficiently, demonstrating that early‐metal polyhydrides can serve as genuine catalysts rather than mere

Comparative assessment of volume‐of‐fluid (VOF) multiphase solvers for viscoplastic flow over grooved patterned surfaces

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Accurately simulating multiphase flows at low capillary numbers remains challenging due to spurious currents and interface discretization errors. We present a systematic comparison of four volume‐of‐fluid (VOF) solvers within the OpenFOAM framework for pressure‐driven Poiseuille–Bingham flow over grooved surfaces: interFoam with classical ...

La thèse des deux mondes et la théorie des communs en appui à la solidarité numérique en éducation au Québec

open access: yesMédiations & Médiatisations, 2022
La solidarité numérique est à la fois un concept en construction et une culture en émergence. Qu’en est-il de la solidarité numérique en éducation au Québec en 2022? La thèse des deux mondes (Aigrain, 2005) permet de camper le dilemme.

Optimal subsampling for regression with mixed‐type predictors

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract Subsampling has emerged as an appealing strategy to mitigate the computational and storage challenges imposed by large datasets. Recent subsampling techniques have shown notable computational gains for data dominated by numerical predictors. However, real‐world datasets frequently contain both numerical and categorical predictors.

Le numérique au service de la valorisation des compétences des jeunes adultes

open access: yesInterfaces Numériques, 2022
Cette contribution questionne les modalités d’apprentissage des jeunes utilisateurs d’interfaces numériques. À la suite d'Auray (2016), nous analysons les aptitudes à maîtriser les environnements numériques, en discutant la typologie en 4 compétences qu ...

Revisiting Fisher's n‐D statistical vision: From algebraic abstraction to modern visualization

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract We revisit early foundational results in mathematical statistics derived by Ronald A. Fisher. They involve sampling distributions of statistics calculated from independent and identically distributed Normal observations, namely the root mean square deviation; the mean absolute deviation, conditional on already knowing the value of the root ...

Bridging Policy Gaps in Transition Times: How Local Actors Navigate Low Policy Coherence for Advancing a Circular Built Environment

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT The construction sector is a major contributor to the climate crisis, accounting for over one‐third of global energy‐related CO2 emissions. In response, the European Commission identified the circular economy as a means of achieving green growth and prioritized the construction sector in its Circular Economy Action Plan.
