Modalities and complications associated with the use of high-flow nasal cannula: experience in a pediatric ICU

F Baudin, S Gagnon, B Crulli, F Proulx, P Jouvet… - Respiratory …, 2016 - rc.rcjournal.com
BACKGROUND: High-flow nasal cannula (HFNC) therapy is increasingly used in pediatric
ICUs as an intermediate level of support between conventional oxygen delivery and …

An application of the statistical downscaling model (SDSM) to simulate climatic data for streamflow modelling in Québec

S Gagnon, B Singh, J Rousselle… - … Water Resources Journal, 2005 - Taylor & Francis
General Circulation Models (GCMs) are widely used tools to assess potential impacts of global
climate warming. However, their outputs are difficult to use in regional impact studies with …

[HTML][HTML] Approach to hemoptysis in the modern era

S Gagnon, N Quigley, H Dutau, A Delage… - Canadian respiratory …, 2017 - hindawi.com
Hemoptysis is a frequent manifestation of a wide variety of diseases, with mild to life-threatening
presentations. The diagnostic workup and the management of severe hemoptysis are …

Aetiology, diagnosis and treatment of moderate-to-severe haemoptysis in a North American academic centre

N Quigley, S Gagnon, M Fortin - ERJ Open Research, 2020 - Eur Respiratory Soc
Significant haemoptysis is a frightening event for patients and clinicians alike. There is a
paucity of contemporary literature on the subject. A retrospective analysis of hospitalisations for …

Dark goo: Bulk viscosity as an alternative to dark energy

JS Gagnon, J Lesgourgues - Journal of Cosmology and …, 2011 - iopscience.iop.org
We present a simple (microscopic) model in which bulk viscosity plays a role in explaining
the present acceleration of the universe. The effect of bulk viscosity on the Friedmann …

Pulmonary rehabilitation

J Bourbeau, S Gagnon, B Ross - Clinics in Chest Medicine, 2020 - chestmed.theclinics.com
With an aging population, the burden of chronic obstructive pulmonary disease (COPD)
continues to rise, impacting patients, their families, the health care system, and the society. The …

Leading order calculation of shear viscosity in hot quantum electrodynamics from diagrammatic methods

JS Gagnon, S Jeon - Physical Review D, 2007 - APS
We compute the shear viscosity at leading order in hot quantum electrodynamics. Starting
from the Kubo relation for shear viscosity, we use diagrammatic methods to write down the …

Leading-order calculation of electric conductivity in hot quantum electrodynamics from diagrammatic methods

JS Gagnon, S Jeon - Physical Review D, 2007 - APS
Using diagrammatic methods, we show how the Ward identity can be used to constrain the
ladder kernel in transport coefficient calculations. More specifically, we use the Ward identity …

Baryon asymmetry of the universe without Boltzmann or Kadanoff-Baym equations

JS Gagnon, M Shaposhnikov - Physical Review D, 2011 - APS
We present a formalism that allows the computation of the baryon asymmetry of the Universe,
from the first principles of statistical physics and quantum field theory, that is applicable to …

[HTML][HTML] Conditions for the origin of homochirality in primordial catalytic reaction networks

JS Gagnon, D Hochberg - Scientific Reports, 2023 - nature.com
We study the generation of homochirality in a general chemical model (based on the
homogeneous, fully connected Smoluchowski aggregation-fragmentation model) that obeys …
