title: A Dynamic Factor Model for Nowcasting Canadian GDP Growth
Creators: name: Chernis, Tony
name: Sekkel, Rodrigo
Publisher: name: Bank of Canada
Year: 2017

description: This paper estimates a dynamic factor model (DFM) for nowcasting Canadian gross domestic product. The model is estimated with a mix of soft and hard indicators, and it features a high share of international data. The model is then used to generate nowcasts, predictions of the recent past and current state of the economy. In a pseudo real-time setting, we show that the DFM outperforms univariate benchmarks as well as other commonly used nowcasting models, such as mixed-data sampling (MIDAS) and bridge regressions.

description: Nous estimons un modèle à facteurs dynamiques (MFD) applicable à la prévision du produit intérieur brut du Canada pour la période en cours. L’estimation du modèle combine des indicateurs qualitatifs et quantitatifs et s’appuie également sur un ensemble de statistiques contenant un grand nombre de données internationales. Le modèle sert ensuite à produire des prévisions pour la période en cours, à savoir pour une période qui englobe le passé récent et la conjoncture immédiate. Dans un environnement où les données sont disponibles en temps quasi réel, nous montrons que le MFD surclasse les modèles univariés de référence ainsi que d’autres modèles fréquemment utilisés pour les prévisions de la période en cours : par exemple, les régressions fondées sur un modèle d’échantillonnage de données de fréquence mixte (MIDAS) et les modèles d’étalonnage.

description: We present classification results for exceptional Legendrian realisations of torus knots. These are the first results of that kind for non-trivial topological knot types. Enumeration results of Ding-Li-Zhang concerning tight contact structures on certain Seifert fibred manifolds with boundary allow us to place upper bounds on the number of tight contact structures on the complements of torus knots; the classification of exceptional realisations of these torus knots is then achieved by exhibiting sufficiently many realisations in terms of contact surgery diagrams. We also discuss a couple of general theorems about the existence of exceptional Legendrian knots.

description: Very recently, J 1128+5925 was found to show strong intraday variability at radio wavelengths and may be a new source with annual modulation of the timescale of its radio variability. Therefore, its radio variability can be best explained via interstellar scintillation. Here we present the properties of its optical variability for the first time after a monitoring program in 2007 May. Our observations indicate that in this period J 1128+5925 only showed trivial optical variability on internight timescale, and did not show any clear intranight variability. This behavior is quite different from its strong radio intraday variability. Either this object was in a quiescent state in optical in this period, or it is intrinsically not so active in optical as it is in radio regimes.

Modeling slow deformation of polygonal particles using DEM

description: We introduce two improvements in the numerical scheme to simulate collision and slow shearing of irregular particles. First, we propose an alternative approach based on simple relations to compute the frictional contact forces. The approach improves efficiency and accuracy of the Discrete Element Method (DEM) when modeling the dynamics of the granular packing. We determine the proper upper limit for the integration step in the standard numerical scheme using a wide range of material parameters. To this end, we study the kinetic energy decay in a stress controlled test between two particles. Second, we show that the usual way of defining the contact plane between two polygonal particles is, in general, not unique which leads to discontinuities in the direction of the contact plane while particles move. To solve this drawback, we introduce an accurate definition for the contact plane based on the shape of the overlap area between touching particles, which evolves continuously in time.

Integrated properties of mass segregated star clusters

description: In this contribution we study integrated properties of dynamically segregated star clusters. The observed core radii of segregated clusters can be 50% smaller than the ``true'' core radius. In addition, the measured radius in the red filters is smaller than those measured in blue filters. However, these difference are small ($\lesssim10%$), making it observationally challenging to detect mass segregation in extra-galactic clusters based on such a comparison. Our results follow naturally from the fact that in nearly all filters most of the light comes from the most massive stars. Therefore, the observed surface brightness profile is dominated by stars of similar mass, which are centrally concentrated and have a similar spatial distribution.

Using Gaussian Boson Sampling to Find Dense Subgraphs
Creators: name: Arrazola, Juan Miguel

Year: 2018
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Boson sampling devices are a prime candidate for exhibiting quantum supremacy, yet their application for solving problems of practical interest is less well understood. Here we show that Gaussian boson sampling (GBS) can be used for dense subgraph identification. Focusing on the NP-hard densest k-subgraph problem, we find that stochastic algorithms are enhanced through GBS, which selects dense subgraphs with high probability. These findings rely on a link between graph density and the number of perfect matchings -- enumerated by the Hafnian -- which is the relevant quantity determining sampling probabilities in GBS. We test our findings by constructing GBS-enhanced versions of the random search and simulated annealing algorithms and apply them through numerical simulations of GBS to identify the densest subgraph of a 30 vertex graph.

description: We present a novel combination of quantum Monte Carlo methods and a finite size extrapolation framework with which we calculate the thermodynamic limit of the exact correlation energy of the polarized electron gas at high densities to meV accuracy, $-40.44(5)$ and $-31.70(4)$ mHa at $r_{\rm s}=0.5$ and $1$, respectively. The fixed-node error is characterized and found to exceed $1$ mHa, and we show that the magnitude of the correlation energy of the polarized electron gas is underestimated by up to $6$ meV by the Perdew-Wang parametrization, for which we suggest improvements.
title: Terms-of-Trade and House Price Fluctuations: A Cross-Country Study
Creators: name: Corrigan, Paul
Publisher: name: Bank of Canada
Year: 2017

description: Terms-of-trade shocks are known to be key drivers of business cycles in open economies. This paper argues that terms-of-trade shocks were also important for house price fluctuations in a panel of developed countries over the 1994–2015 period. In a panel vector error-correction model of house prices, household debt and real tradable prices, terms-of-trade shocks explain between 16 and 41 per cent of the long-run variance in house price growth in a typical country, and from 45 to 85 per cent of the long-run variance of the ratio of house prices to non-housing consumption. Most of the variation in the house price/consumption ratio is associated with changes in real import prices, with idiosyncratic shocks to real export prices playing a minor role. On average, a permanent 1 per cent decline in real import prices raises the ratio of real house prices to non-housing consumption by about 0.9 per cent.
description: Les chocs des termes de l’échange sont d’importants déterminants des cycles économiques dans les économies ouvertes. Dans cet article, nous soutenons que ces chocs ont aussi eu une incidence notable sur les variations des prix des logements dans un groupe de pays développés, de 1994 à 2015. Dans un modèle vectoriel à correction d’erreurs appliqué à des données de panel sur les prix des logements, l’endettement des ménages et les prix réels des biens échangeables, les chocs des termes de l’échange expliquent entre 16 et 41 % de la variance à long terme de la croissance des prix des logements dans un pays type, et de 45 à 85 % de la variance à long terme du ratio des prix des logements à la consommation hors logement. Le gros de la variation du ratio prix des logements-consommation est associé aux mouvements des prix réels des importations, alors que les chocs idiosyncrasiques touchant les prix réels des exportations jouent un rôle mineur. En moyenne, une baisse durable de 1 % des prix réels à l’importation fait augmenter d’environ 0,9 % le ratio prix réels des logements-consommation hors logement.

description: Standardizing and incentivizing the use of digital object identifiers (DOIs) to aggregate and identify both data analyzed and data generated by a research project will advance the field of astronomy to match best practices in other research fields like geosciences and medicine. Increase in the use of DOIs will prepare the discipline for changing expectations among funding agencies and publishers, who increasingly expect accurate and thorough data citation to accompany scientific outputs. The use of DOIs ensures a robust, sustainable, and interoperable approach to data citation in which due credit is given to researchers and institutions who produce and maintain the primary data. We describe in this work the advantages of DOIs for data citation and best practices for integrating a DOI service in an astronomical archive. We report on a pilot project carried out in collaboration with AAS Journals. During the course of the 1.5 year pilot, over 75% of submitting authors opted to use the integrated DOI service to clearly identify data analyzed during their research project when prompted at the time of paper submission.

title: Identification and Estimation of Risk Aversion in First-Price Auctions with Unobserved Auction Heterogeneity
Creators: name: Grundl, Serafin
name: Zhu, Yu
Publisher: name: Bank of Canada
Year: 2016

description: This paper shows point identification in first-price auction models with risk aversion and unobserved auction heterogeneity by exploiting multiple bids from each auction and variation in the number of bidders. The required exclusion restriction is shown to be consistent with a large class of entry models. If the exclusion restriction is violated, but weaker restrictions hold instead, the same identification strategy still yields valid bounds for the primitives. We propose a sieve maximum likelihood estimator. A series of Monte Carlo experiments illustrate that the estimator performs well in finite samples and that ignoring unobserved auction heterogeneity can lead to a significant bias in risk-aversion estimates. In an application to U.S. Forest Service timber auctions we find that the bidders are risk neutral, but we would reject risk neutrality without accounting for unobserved auction heterogeneity.
description: Nous présentons une méthode d’identification ponctuelle dans le cadre de modèles d’enchères au premier prix où sont prises en compte l’aversion au risque et une hétérogénéité non observée des enchères. La méthode d’identification proposée s’appuie sur de multiples offres tirées de chaque enchère et sur le nombre variable d’offreurs. L’hypothèse d’exclusion retenue est compatible avec une classe étendue de modèles formalisant les décisions d’entrée. Si cette hypothèse d’exclusion est violée mais que des restrictions moins strictes demeurent, la même stratégie d’identification aboutit à des bornes valides pour les primitives. Nous proposons un estimateur du maximum de vraisemblance par tamisage local. À partir d’une série de simulations de Monte-Carlo, il est montré que cet estimateur donne de bons résultats sur des échantillons finis et que ne pas prendre en compte l’hétérogénéité non observée des enchères peut causer un biais significatif des estimations de l’aversion au risque. En appliquant notre méthode aux enchères organisées par le Service des forêts des États-Unis pour l’adjudication de bois d’oeuvre, nous constatons que les offreurs sont neutres à l’égard du risque; cependant, en ignorant l’hétérogénéité non observée des enchères, nous rejetterions cette neutralité.

description: A perturbatively renormalized Abelian Higgs-Kibble model with a chirally coupled fermion is considered. The Slavnov identity is fulfilled to all orders of perturbation theory, which is crucial for renormalizability in models with vector bosons. BRS invariance, i.e. the validity of the identity, forces the chiral anomaly to be cancelled by Wess-Zumino counterterms. This procedure preserves the renormalizability in the one-loop approximation but it violates the Froissart bounds for partial wave amplitudes above some energy and destroys renormalizability from the second order in h bar onwards due to the counterterms.

description: For a Lie group G and a smooth manifold W, we study the difference between smooth actions of G on W and bundles over the classifying space of G with fiber W and structure group Diff(W). In particular, we exhibit smooth manifold bundles over BSU(2) that are not induced by an action. The main tool for reaching this goal is a technical result that gives a constraint for the values of tautological classes pulled back to the cohomology of BSU(2) along a map induced by an action.

Interplay between speed and fidelity in off-resonant quantum-state transfer protocols

Publisher: name: arXiv

subject: FOS: Physical sciences

description: An arbitrary qubit can be transmitted through a spin chain by perturbatively coupling both communicating parties to it. Those so-called weak-coupling models rely on effective Rabi oscillations between them, yielding nearly maximum fidelity while offering great resilience against disorder with the cost of having long transfer times. Considering this framework, here we address a 1D non-symmetric channel connecting two spins, one placed at each end of it. Given any pattern of nearest-neighbor coupling strengths, we obtain an analytical expression that accounts for the effective long-range interaction between them and study the interplay between transfer time and fidelity. Furthermore, we show that homogeneous channels provide the best speed-fidelity tradeoff.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

Publisher: name: Bank of Canada

description: We model how securities dealers respond to regulations on leverage, position, and liquidity such as those imposed by the Basel III framework. The dealers respond by endogenously moving to make markets on an agency basis, matching buyers to sellers rather than taking client positions on the balance sheet. Agency-based market making creates a cost-risk tradeoff in which investor welfare declines but dealers become less risky. The costs to investors do not show up in all liquidity metrics: while asset prices exhibit greater price impact, bid-ask spreads do not change and trading volumes can even increase, which can help explain the varying findings from the empirical literature.
description: Dans notre étude, nous modélisons la réaction des maisons de courtage aux exigences réglementaires relatives aux fonds propres, aux positions et aux liquidités, comme celles du dispositif de Bâle III. Les courtiers réagissent par des mouvements endogènes afin d’assurer la tenue de marché pour le compte de tiers : ils jumellent des ordres d’achat et de vente au lieu de détenir les positions de leurs clients dans leur bilan. La tenue de marché pour le compte de tiers crée un arbitrage entre les coûts et les risques qui réduit le bien-être des investisseurs mais aussi les risques auxquels les courtiers s’exposent. Les coûts assumés par les investisseurs ne sont pas captés dans toutes les mesures de la liquidité. Si les prix des actifs sont davantage touchés, les écarts entre les cours acheteur-vendeur ne changent pas et les volumes des opérations peuvent même augmenter, ce qui pourrait expliquer les conclusions divergentes des études empiriques.

description: We study the non-equilibrium dynamics of a symmetry restoring phase transition in a scalar field theory, the ``system'', linearly coupled to another scalar field taken as a ``heat bath''. The ``system'' is initially in an ordered low temperature phase, and the heat bath is at a temperature close to the critical temperature for the system. We estimate the time at which the phase transition to the disordered (symmetric) phase takes place. We derive, and integrate the one-loop effective equations of motion for the order parameter that include the effects of the heat bath. A semiclassical Langevin equation is derived and it is found that it contains a non-dissipative, non-Markovian kernel, the noise term is colored and correlated on time scales determined by the temperature of the heat bath. The range of validity of the Langevin equation and a consistent procedure to incorporate corrections are discussed.

description: Bell's Theorem proved that one cannot in general reproduce the results of quantum theory with a classical, deterministic local model. However, Einstein originally considered the case where one could define an 'element of reality', namely for the much simpler case where one could predict with certainty a definite outcome for an experiment. For this simple case, Bell's Theorem says nothing. But by using a slightly more complicated model than Bell, one can show that even in this simple case where one can make definite predictions, one still cannot generally introduce deterministic, local models to explain the results.

A perturbation moving near the potential barrier can create a large-distance black hole geometry where the seeming curvature singularity is at the position of the barrier. In the simplest `static' case the exact $D=2$ black hole metric emerges.

description: The structure and dynamics of one-dimensional binary Bose gases forming quantum droplets is studied by solving the corresponding amended Gross-Pitaevskii equation. Two physically different regimes are identified, corresponding to small droplets of an approximately Gaussian shape and large `puddles' with a broad flat-top plateau. Small droplets collide quasi-elastically, featuring the soliton-like behavior. On the other hand, large colliding droplets may merge or suffer fragmentation, depending on their relative velocity. The frequency of a breathing excited state of droplets, as predicted by the dynamical variational approximation based on the Gaussian ansatz, is found to be in good agreement with numerical results. Finally, the stability diagram for a single droplet with respect to shape excitations with a given wave number is drawn, being consistent with preservation of the Weber number for large droplets.

title: Corporate investment and monetary policy transmission in Canada
Creators: name: Kim, Min Jae
name: Witmer, Jonathan
Publisher: name: Bank of Canada
Year: 2020

description: Unexpected changes in interest rates lead small firms to materially change their investment rate. Large firms, in contrast, show a smaller response. This suggests both that financial conditions are an important channel for transmitting monetary policy and that firm characteristics can help us better understand fluctuations in business investment.

description: Quand les taux d’intérêt varient de façon inattendue, les petites entreprises modifient nettement leur taux d’investissement. Les grandes entreprises, elles, ont une réaction plus modérée. Ce constat donne à penser que les conditions financières sont un important canal de transmission de la politique monétaire et que les caractéristiques des entreprises peuvent nous aider à mieux comprendre les fluctuations de leurs investissements.
Transgression and Clifford algebras

description: Let $W$ be a differential (not necessarily commutative) algebra which carries a free action of a polynomial algebra $SP$ with homogeneous generators $p_1, >..., p_r$. We show that for $W$ acyclic, the cohomology of the quotient $H(W/)$ is isomorphic to a Clifford algebra $\text{Cl}(P,B)$, where the (possibly degenerate) bilinear form $B$ depends on $W$. This observation is an analogue of an old result of Borel in a non-commutative context. As an application, we study the case of $W$ given by the quantized Weil algebra $\qWg = \Ug \otimes \Clg$ for $\Lieg$ a reductive Lie algebra. The resulting cohomology of the canonical Weil differential gives a Clifford algebra, but the bilinear form vanishes on the space of primitive invariants of the semi-simple part. As an application, we consider the deformed Weil differential (following Freed, Hopkins and Teleman).

Publisher: name: Bank of Canada
Year: 2020

description: The neutral rate of interest is important for central banks because it helps measure the stance of monetary policy. We present updated estimates of the neutral rate in Canada using the most recent data. We expect the COVID-19 pandemic to significantly affect the fundamental drivers of the Canadian neutral rate.

description: Le taux d’intérêt neutre est important pour les banques centrales, car il aide à mesurer l’orientation de la politique monétaire. En nous fondant sur les plus récentes données, nous présentons des estimations actualisées du taux neutre canadien, dont les facteurs fondamentaux devraient être grandement touchés par la pandémie de COVID-19.
Search for supersymmetry in events with four or more leptons in $\sqrt{s}=13$ TeV $pp$ collisions with ATLAS
Creators: name: ATLAS Collaboration
Publisher: name: arXiv
Year: 2018
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: Results from a search for supersymmetry in events with four or more charged leptons (electrons, muons and taus) are presented. The analysis uses a data sample corresponding to 36.1 fb$^{-1}$ of proton-proton collisions delivered by the Large Hadron Collider at $\sqrt{s}=13$ TeV and recorded by the ATLAS detector. Four-lepton signal regions with up to two hadronically decaying taus are designed to target a range of supersymmetric scenarios that can be either enriched in or depleted of events involving the production and decay of a $Z$ boson. Data yields are consistent with Standard Model expectations and results are used to set upper limits on the event yields from processes beyond the Standard Model. Exclusion limits are set at the 95% confidence level in simplified models of General Gauge Mediated supersymmetry, where higgsino masses are excluded up to 295 GeV. In $R$-parity-violating simplified models with decays of the lightest supersymmetric particle to charged leptons, lower limits of 1.46 TeV, 1.06 TeV, and 2.25 TeV are placed on wino, slepton and gluino masses, respectively.

Consistency and lattice renormalization of the effective theory for heavy quarks
Creators: name: Aglietti, Ugo
Publisher: name: arXiv
Year: 1993
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: The effective theory describing infinite mass particles with a given velocity, has a great interest in heavy flavor physics. It has the unpleasant characteristic that the energy spectrum is unbounded from below; this fact is the source of the problems in the formulation of the euclidean theory. In this paper we present an analysis of the euclidean effective theory, that is rather complete and has positive conclusions. A proof of the consistency of the euclidean theory is presented and a technique for the evaluation of the amplitudes in perturbation theory is described. We compute also the one-loop renormalization constants of the lattice effective theory and of the heavy-heavy current that is needed for the determination of the Isgur-Wise function. A variety of effects related to the explicit breaking of the Lorentz symmetry of lattice regularization is demonstrated. The most peculiar phenomenon is that the heavy quark velocity receives a finite renormalization. Finally, we compute the lattice-continuum renormalization constant of the Isgur-Wise current. It is needed for the conversion of the values of the matrix elements computed with the lattice effective theory, to the values in the full theory.

title: Potential output in Canada: 2020 reassessment
Creators: name: Brouillette, Dany
name: Champagne, Julien
name: McDonald-Guimond, Julien
Publisher: name: Bank of Canada
Year: 2020

description: After COVID-19, we expect potential output growth to stabilize around 1.2 percent. This is lower than the 2010–18 average growth of 1.8 percent. Relative to the April 2019 reassessment, the growth profile is revised down. Given the unknown course of the pandemic, uncertainty around these estimates is higher than in previous years.

description: Après la crise de la COVID-19, la croissance de la production potentielle devrait se stabiliser à environ 1,2 %, ce qui est inférieur à la croissance moyenne de 1,8 % observée de 2010 à 2018. Le profil de croissance a été revu à la baisse par rapport à celui établi lors de la réévaluation d’avril 2019. Comme l’évolution de la pandémie est inconnue, ces estimations sont empreintes d’une plus grande incertitude que dans les années précédentes.
A Linear Equation for Wilson Loops

description: The Makeenko-Migdal loop equation is non-linear and first order in the area derivative, but we show that for simple loops in QCD$_2$ it is possible to reformulate this equation as a linear equation with second order derivatives. This equation is a bound state Schrödinger equation with a three dimensional Coulomb potential. Thus, loop dynamics leads to a surprising new picture of confinement, where this phenomenon is due to a (bound state) localization in loop space, with the Wilson loops decaying exponentially outside a characteristic radius.

description: We leverage new high-quality data from Hubble Space Telescope program GO-14164 to explore the variation in horizontal branch morphology among globular clusters in the Large Magellanic Cloud (LMC). Our new observations lead to photometry with a precision commensurate with that available for the Galactic globular cluster population. Our analysis indicates that, once metallicity is accounted for, clusters in the LMC largely share similar horizontal branch morphologies regardless of their location within the system. Furthermore, the LMC clusters possess, on average, slightly redder morphologies than most of the inner halo Galactic population; we find, instead, that their characteristics tend to be more similar to those exhibited by clusters in the outer Galactic halo. Our results are consistent with previous studies showing a correlation between horizontal branch morphology and age.

description: The connection between supersymmetric quantum mechanics and the Korteweg- de Vries (KdV) equation is discussed, with particular emphasis on the KdV conservation laws. It is shown that supersymmetric quantum mechanics aids in the derivation of the conservation laws, and gives some insight into the Miura transformation that converts the KdV equation into the modified KdV equation. The construction of the $τ$-function by means of supersymmetric quantum mechanics is discussed.

description: The q-deformed harmonic oscillator within the framework of the recently introduced Schwenk-Wess $q$-Heisenberg algebra is considered. It is shown, that for "physical" values $q\sim1$, the gap between the energy levels decreases with growing energy. Comparing with the other (real) $q$-deformations of the harmonic oscillator, where the gap instead increases, indicates that the formation of the macroscopic energy gap in the Schwenk-Wess $q$-Quantum Mechanics may be avoided.
