The JCMT Gould Belt Survey: A First Look at Dense Cores in Orion B
H. Kirk, J. Di Francesco, D. Johnstone +54
We present a first look at the SCUBA-2 observations of three sub-regions of the Orion B molecular cloud: LDN 1622, NGC 2023/2024, and NGC 2068/2071, from the JCMT Gould Belt Legacy…
Integral Iwasawa theory of Galois representations for non-ordinary primes
Kazim Büyükboduk, Antonio Lei
In this paper, we study the Iwasawa theory of a motive whose Hodge-Tate weights are or (thence in practice, of a motive associated to an abelian variety) at a non-ordinary…
Direct imaging of molecular symmetry by coherent anti-Stokes Raman scattering
Carsten Cleff, Alicja Gasecka, Patrick Ferrand +3
Nonlinear optical methods, such as coherent anti-Stokes Raman scattering (CARS) and stimulated Raman scattering (SRS), are able to perform label free imaging, with chemical bonds s…
N>=2 symmetric superpolynomials
L. Alarie-Vézina, L. Lapointe, P. Mathieu
The theory of symmetric functions has been extended to the case where each variable is paired with an anticommuting one. The resulting expressions, dubbed superpolynomials, provide…
On the harmonic measure and capacity of rational lemniscates
Stamatis Pouliasis, Thomas Ransford
We study the lemniscates of rational maps. We prove a reflection principle for the harmonic measure of rational lemniscates and we give estimates for their capacity and the capacit…
On the asymptotic growth of Bloch-Kato-Shafarevich-Tate groups of modular forms over cyclotomic extensions
Antonio Lei, David Loeffler, Sarah Zerbes
We study the asymptotic behaviour of the Bloch-Kato-Shafarevich-Tate group of a modular form f over the cyclotomic Zp-extension of Q under the assumption that f is non-ordinary at…
Rigorous numerics for ill-posed PDEs: periodic orbits in the Boussinesq equation
R. Castelli, M. Gameiro, J. -P. Lessard
In this paper, we develop computer-assisted techniques for the analysis of periodic orbits of ill-posed partial differential equations. As a case study, our proposed method is appl…
CdSe Colloidal Quantum Rings
Sébastien Lamarre, Étienne Rochette, Samuel Tremblay +1
Atomically flat semiconductor nanostructures have sharp photoluminescence emission, short radiative lifetimes and a well-defined planar structure. However, these nanostructures lac…
Measurements of stellar magnetic fields with the autocorrelation of spectra
Ermanno F. Borra, David Deschatelets
We present a novel technique that uses the autocorrelation of the spectrum of a star to measure the line broadening caused by the modulus of its average surface magnetic field. The…
General and exact approach to percolation on random graphs
Antoine Allard, Laurent Hébert-Dufresne, Jean-Gabriel Young +1
We present a comprehensive and versatile theoretical framework to study site and bond percolation on clustered and correlated random graphs. Our contribution can be summarized in t…
The JCMT Plane Survey: early results from the l = 30 degree field
T. J. T. Moore, R. Plume, M. A. Thompson +55
We present early results from the JCMT Plane Survey (JPS), which has surveyed the northern inner Galactic plane between longitudes l=7 and l=63 degrees in the 850-μm continuum with…
Direct observation of laser guided corona discharges
Tie-Jun Wang, Yingxia Wei, Yaoxiang Liu +10
Laser based lightning control holds a promising way to solve the problem of the long standing disaster of lightning strikes. But it is a challenging project due to insufficient und…
Consistency of Scalar Potentials from Quantum de Sitter Space
José R. Espinosa, Jean-François Fortin, Maxime Trépanier
Consistency of the unconventional view of de Sitter space as a quantum theory of gravity with a finite number of degrees of freedom requires that Coleman-De Luccia tunneling rates…
Bayesian Statistics as a New Tool for Spectral Analysis: I. Application for the Determination of Basic Parameters of Massive Stars
J-M. Mugnes, C. Robert
Spectral analysis is a powerful tool to investigate stellar properties and it has been widely used for decades now. However, the methods considered to perform this kind of analysis…
Constructive feedback for the growth of laser-induced periodic surface structures
Jean-Luc Déziel, Joey Dumont, Denis Gagnon +3
We study the formation and growth of laser-induced periodic surface structures (LIPSSs) with the finite-difference time-domain (FDTD) method. We use a recently proposed inter-pulse…
A General Hidden State Random Walk Model for Animal Movement
Aurélien Nicosia, Thierry Duchesne, Louis-Paul Rivest +1
In this paper, we propose a general hidden state random walk model to describe the movement of an animal that takes into account movement taxis with respect to features of the envi…
Rank one perturbations of diagonal operators without eigenvalues
Hubert Klaja
In this paper, we prove that every diagonal operator on a Hilbert space of which is of multiplicity one and has perfect spectrum admits a rank one perturbation without eigenvalues.…
Tunneling decay of false kinks
Éric Dupuis, Yan Gobeil, Richard MacKenzie +3
We consider the decay of "false kinks," that is, kinks formed in a scalar field theory with a pair of degenerate symmetry-breaking false vacua in 1+1 dimensions. The true vacuum is…
A New PAC-Bayesian Perspective on Domain Adaptation
Pascal Germain, Amaury Habrard, François Laviolette +1
We study the issue of PAC-Bayesian domain adaptation: We want to learn, from a source domain, a majority vote model dedicated to a target one. Our theoretical contribution brings a…
A Closer Look at the Light Induced Changes in the Visco-elastic Properties of Azobenze-Containing Polymers by Statistical Nanoindentation
Luca Sorelli, Filippo Fabbri, Jessy Frech-Baronet +7
The mechanical properties of azobenzene-containing polymer films are statistically measured by instrumented nanoindentation experiment in the dark and under illumination in the abs…
Greedy Biomarker Discovery in the Genome with Applications to Antimicrobial Resistance
Alexandre Drouin, Sébastien Giguère, Maxime Déraspe +3
The Set Covering Machine (SCM) is a greedy learning algorithm that produces sparse classifiers. We extend the SCM for datasets that contain a huge number of features. The whole gen…
MeV femtosecond electron pulses from direct-field acceleration in low density atomic gases
Charles Varin, Vincent Marceau, Pascal Hogan-Lamarre +3
Using three-dimensional particle-in-cell simulations, we show that few-MeV electrons can be produced by focusing tightly few-cycle radially-polarized laser pulses in a low-density…
Domain-Adversarial Training of Neural Networks
Yaroslav Ganin, Evgeniya Ustinova, Hana Ajakan +5
We introduce a new representation learning approach for domain adaptation, in which data at training and test time come from similar but different distributions. Our approach is di…
Lorenz-Mie theory for 2D scattering and resonance calculations
