Steklov eigenvalues and quasiconformal maps of simply connected planar domains
A. Girouard, R. S. Laugesen, B. A. Siudeja
We investigate isoperimetric upper bounds for sums of consecutive Steklov eigenvalues of planar domains. The normalization involves the perimeter and scale-invariant geometric fact…
The JCMT Gould Belt Survey: Evidence for radiative heating in Serpens MWC 297 and its influence on local star formation
D. Rumble, J. Hatchell, R. A. Gutermuth +61
We present SCUBA-2 450micron and 850micron observations of the Serpens MWC 297 region, part of the JCMT Gould Belt Survey of nearby star-forming regions. Simulations suggest that r…
Weight modules for current algebras
Daniel Britten, Michael Lau, Frank Lemire
For any finite-dimensional simple Lie algebra and commutative associative algebra of finite type, we give a complete classification of the simple weight modules…
Quantitative evaluation of the hypothesis that BL Lacertae objects are QSO remnants
E. F. Borra
We evaluate with numerical simulations the hypothesis that BL Lacertae objects are the remnants of Quasi Stellar Objects. This hypothesis is based on their highly peculiar redshift…
Toward the formation of crossed laser-induced periodic surface structures
Jean-Luc Déziel, Joey Dumont, Denis Gagnon +3
The formation of a new type of laser-induced periodic surface structures using a femtosecond pulsed laser is studied on the basis of the Sipe-Drude theory solved with a FDTD scheme…
The effect of spatial resolution on optical and near-IR studies of stellar clusters: Implications for the origin of the red excess
N. Bastian, A. Adamo, M. Schirmer +6
Recent ground based near-IR studies of stellar clusters in nearby galaxies have suggested that young clusters remain embedded for 7-10Myr in their progenitor molecular cloud, in co…
Cyclic polynomials in two variables
Catherine Bénéteau, Greg Knese, Łukasz Kosiński +3
We give a complete characterization of polynomials in two complex variables that are cyclic with respect to the coordinate shifts acting on Dirichlet-type spaces in the bidisk, whi…
Schur Superpolynomials: Combinatorial Definition and Pieri Rule
Olivier Blondeau-Fournier, Pierre Mathieu
Schur superpolynomials have been introduced recently as limiting cases of the Macdonald superpolynomials. It turns out that there are two natural super-extensions of the Schur poly…
On the Generalization of the C-Bound to Structured Output Ensemble Methods
François Laviolette, Emilie Morvant, Liva Ralaivola +1
This paper generalizes an important result from the PAC-Bayesian literature for binary classification to the case of ensemble methods for structured outputs. We prove a generic ver…
A unified framework for thermal face recognition
Reza Shoja Ghiass, Ognjen Arandjelovic, Hakim Bendada +1
The reduction of the cost of infrared (IR) cameras in recent years has made IR imaging a highly viable modality for face recognition in practice. A particularly attractive advantag…
Optimization of integrated polarization filters
Denis Gagnon, Joey Dumont, Jean-Luc Déziel +1
This study reports on the design of small footprint, integrated polarization filters based on engineered photonic lattices. Using a rods-in-air lattice as a basis for a TE filter a…
SPIRou: the near-infrared spectropolarimeter/high-precision velocimeter for the Canada-France-Hawaii telescope
Étienne Artigau, Driss Kouach, Jean-François Donati +30
SPIRou is a near-IR échelle spectropolarimeter and high-precision velocimeter under construction as a next-generation instrument for the Canada-France-Hawaii-Telescope. It is desig…
The Snapshot Hubble U-Band Cluster Survey (SHUCS) II. Star Cluster Population of NGC 2997
J. E. Ryon, A. Adamo, N. Bastian +6
We study the star cluster population of NGC 2997, a giant spiral galaxy located at 9.5 Mpc and targeted by the Snapshot Hubble U-band Cluster Survey (SHUCS). Combining our U-band i…
Adding SALT to Coupled Microcavities: the making of active photonic molecule lasers
Denis Gagnon, Joey Dumont, Jean-Luc Déziel +1
A large body of work has accumulated over the years in the study of the optical properties of single and coupled microcavities for a variety of applications, ranging from filters t…
Cloud angular momentum and effective viscosity in global SPH simulations with feedback
David J. Williamson, Robert J. Thacker, James Wurster +1
We examine simulations of isolated galaxies to analyse the effects of localised feedback on the formation and evolution of molecular clouds. Feedback contributes to turbulence and…
Major Cluster Mergers and the Location of the Brightest Cluster Galaxy
Hugo Martel, Fidèle Robichaud, Paramita Barai
Using a large N-body cosmological simulation combined with a subgrid treatment of galaxy formation, we study the formation and evolution of the galaxy and cluster population in a c…
High Velocity-dispersion Cold Gas in ULIRG Outflows. I: Direct Simulations
David J. Williamson, Robert J. Thacker, Evan Scannapieco +1
Observations have revealed cold gas with large velocity dispersions (~300 km/s) within the hot outflows of ultra-luminous infrared galaxies (ULIRGs). This gas may trace its origin…
The supersymmetric Ruijsenaars-Schneider model
Olivier Blondeau-Fournier, Patrick Desrosiers, Pierre Mathieu
An integrable supersymmetric generalization of the trigonometric Ruijsenaars-Schneider model is presented whose symmetry algebra includes the super Poincaré algebra. Moreover, its…
Very long baseline interferometry and observations of gravitational lenses using intensity fluctuations: an analysis based on intensity autocorrelation
Ermanno F. Borra
A novel interferometric technique that uses the spectrum of the current fluctuations of a quadratic detector, a type of detector commonly used in Astronomy, has recently been intro…
The Age Distribution of Clusters in M83
E. Silva-Villa, A. Adamo, N. Bastian +2
In order to empirically determine the timescale and environmental dependence of stellar cluster disruption, we have undertaken an analysis of the unprecedented multi-pointing (seve…
Sequential Model-Based Ensemble Optimization
Alexandre Lacoste, Hugo Larochelle, François Laviolette +1
One of the most tedious tasks in the application of machine learning is model selection, i.e. hyperparameter selection. Fortunately, recent progress has been made in the automation…
Counting-Based Search: Branching Heuristics for Constraint Satisfaction Problems
Gilles Pesant, Claude-Guy Quimper, Alessandro Zanarini
Designing a search heuristic for constraint programming that is reliable across problem domains has been an important research topic in recent years. This paper concentrates on one…
