description: We analyse the Weak Gravity Conjecture for chiral four-dimensional F-theory compactifications with N=1 supersymmetry. Extending our previous work on nearly tensionless heterotic strings in six dimensions, we show that under certain assumptions a tower of asymptotically massless states arises in the limit of vanishing coupling of a U(1) gauge symmetry coupled to gravity. This tower contains super-extremal states whose charge-to-mass ratios are larger than those of certain extremal dilatonic Reissner-Nordstrom black holes, precisely as required by the Weak Gravity Conjecture. Unlike in six dimensions, the tower of super-extremal states does not always populate a charge sub-lattice. The main tool for our analysis is the elliptic genus of the emergent heterotic string in the chiral N=1 supersymmetric effective theories. This also governs situations where the heterotic string is non-perturbative. We show how it can be computed in terms of BPS invariants on elliptic four-folds, by making use of various dualities and mirror symmetry. Compared to six dimensions, the geometry of the relevant elliptically fibered four-folds is substantially richer than that of the three-folds, and we classify the possibilities for obtaining critical, nearly tensionless heterotic strings. We find that the (quasi-)modular properties of the elliptic genus crucially depend on the choice of flux background. Our general results are illustrated in a detailed example.

description: System of Dirac fermions with random-varying mass is studied in detail. We reformulate the system by transfer-matrix formalism. Eigenvalues and wave functions are obtained numerically for various configurations of random telegraphic mass m(x). Localized and extended states are identified. For quasi-periodic m(x), low-energy wave functions are also quasi-periodic and extended, though we are not imposing the periodic boundary condition on wave function. On increasing the randomness of the varying mass, states lose periodicity and most of them tend to localize. At the band center or the low-energy limit, there exist extended states which have more than one peak spatially separate with each other comparatively large distance. Numerical calculations of the density of states and ensemble averaged Green's functions are explicitly given. They are in good agreement with analytical calculations by using the supersymmetric methods and exact form of the zero-energy wave functions.

Subjects: sociolinguistics; variational linguistics; German language; Kiezdeutsch; multiethnolect; multilingualism

description: This contribution deals with Kiezdeutsch, a form of youth slang spoken in multilingual and multi-ethnic urban settings in Germany. Based on three works by German scholars published in the past few years the linguistic features of Kiezdeutsch are described and the issues of its sociolinguistic status and of its origin are discussed. Then, the role played by Kiezdeutsch in present day German society is scrutinized relying on the dichotomy ‘community vs. migrancy’.

description: La morte di Danton (1835) di Georg Büchner contrappone la ricerca da parte di Camille Desmoulin della “x sconosciuta”, capace di porre fine allo scontro con l’altro, esterno e interno in nome del principio della possibilità, al principio di realtà cui si ispira l’azione dei Giacobini e degli Indulgenti, basata sul precetto di Carneade. La morte dell’avversario (1959) di Hans Keilson, concepito nel 1942, radicalizza l’impostazione dicotomica del dramma di Büchner. Nonostante l’antagonista sia ispirato ad Adolf Hitler, il protagonista, un giovane ebreo in esilio, oppone all’inimicizia l’utopia-ucronia del qui ed ora, un’alternativa autenticamente morale in cui la scelta interiore ed esteriore coincidono. Nei drammatici anni del regime hitleriano riprende la “ricerca della x sconosciuta”, di forme di umana convivenza che neghino le dinamiche della violenza. Sostenere questa sfida nel con-fronto con Hitler, consente non solo ai tedeschi di intravedere le matrici di ogni conflitto. Infine, al-cune pagine hegeliane del periodo jenese (1801-1806), esemplificano la valenza sociale del vincolo nemicale tra il protagonista e B. nel romanzo di Keilson.

description: We propose a kind of Ginzburg--Landau equation with quenched randomness. There is a pinning--depinning transition in the system when the external magnetic force is changed. The transition is self-organized when the external magnetic field is slowly changed under the demagnetizing effect. The total magnetization increases stepwise and the probability distribution of the increase in the total magnetization approximately obeys a power law. A hysteresis loop is obtained when the external magnetic field is changed reciprocally. In our model, the coercivity in the magnetization curve is expressed as the critical value for the pinning-depinning transition.

We show that whilst Dong and Ma's [5] quasi - exact ground - state solution (in D=2) is beyond doubt, their solution for the first excited state is exotic. Quasi - exact solutions for the ground and first excited states are also given for the above potential confined to an impenetrable cylindrical (D=2) or spherical (D=3) wall.

description: New inelastic X-ray scattering experiments have been performed in liquid lithium at two different temperatures: T=475 K (slightly above the melting point) and 600 K. Taking advantage of the absence of any kinematical restriction and incoherent contribution, and pushing the instrumental resolution up to 1.5 meV, it was possible to perform an accurate investigation of the dynamic structure factor S(Q,E) in the wavevector range from 1 to 110 nm^-1. For Q smaller than Q_m=25 nm^-1, the position of the main peak of the static structure factor, a detailed analysis of the lineshapes shows that any picture of the relaxation mechanisms based on a simple viscoelastic model must be abandoned. All the spectral features can instead satisfactorily be accounted for by including both fast and slow relaxation processes. The physical origin of the slow relaxation is associated to the structural rearrangement, while the local nature of the fast one is extensively discussed. At larger Q values a gradual crossover from the strongly correlated to single particle dynamics occurs, with an important weight provided by quantum effects.

description: The following paper is the result of two fieldwork experiences: the observation of the progressive loss of the traditional language by the indigenous kichwa group of the Peruvian Amazon forest and my last stay in the city of Donostia-San Sebastián (Euskal Herria). These experiences allowed me to develop some reflections about the contact between these (apparently different) two worlds: the Native Communities of South America and euskaldunak people. Garabide, a basque non-governmental association, is now helping several indigenous communities making up their linguistic and identity recovery process. In this paper I’ll propose the concept of "linguistic utopia": Garabide is offering to the aforementioned communities practical and theoretical tools, obtained from the long and arduous experience of basque linguistic recovery. This case study will serve as a pretext for developing wider considerations around the Basque idiom, understood not only as an expression of an ethnolinguistic and identity movement. The Euskera language is today considered the realization of a shared and concretized utopia that can be "taught" to others.

description: We investigate the previously proposed possibility that multi-epoch broadband polarimetry could act as a complement or limited proxy for VLBI observations of blazars, in that the number of polarised emission components in the jet, and some of their properties and those of the foreground environment, might be inferred from the object's time-varying 1D Faraday depth spectrum (FDS) alone. We report on a pilot-scale experiment designed to establish the basic plausibility and utility of this idea. We analyse temporal changes in the complex polarisation spectra of nine spatially unresolved (at arcsecond scales) blazars in two epochs separated by $\sim$5 years, using data taken with the Australia Telescope Compact Array. The data allow for precise modelling, and we demonstrate that all objects in our sample show changes in their polarisation spectrum that cannot be accounted for by uncertainties in calibration or observational effects. By associating polarised emission components across epochs, we infer changes in their number, intrinsic fractional polarisation, intrinsic polarisation angle, rotation measure, and depolarisation characteristics. We attribute these changes to evolution in the structure of the blazar jets, most likely located at distances of up to tens of parsecs from the central active galactic nuclei. Our results suggest that continued work in this area is warranted; in particular, it will be important to determine the frequency ranges and temporal cadence most useful for scientifically exploiting the effects.

title: An Improved Equation for Predicting Canadian Non-Commodity Exports
Creators: name: Alexander, Patrick

Publisher: name: Bank of Canada
Year: 2017

description: We estimate two new equations for Canadian non-commodity exports (NCX) that incorporate three important changes relative to the current equation used at the Bank of Canada. First, we develop two new foreign activity measures (FAMs), which add new components to the FAM currently used at the Bank of Canada. The first measure adds US exports and US government expenditures, and the second adds US industrial production. These new FAMs calibrate the weights on the various components based on the 2014 World Input-Ouput Database to avoid the instability problem that arises when the equations are estimated. Second, we add a new variable to the equations, the trend of Canada’s manufacturing share of output, to control for structural or competitiveness factors that affect Canada’s global import market share. Third, the relative price of exports is determined by a new measure of the Canadian real effective exchange rate developed by Barnett, Charbonneau and Poulin-Bellisle (2016). We find that the new equations improve the in-sample fit and the out-of-sample forecast accuracy relative to the current equation specified in “LENS,” a forecasting model used at the Bank of Canada.
description: Nous estimons deux nouvelles équations des exportations hors produits de base qui incorporent trois changements importants par rapport à l’équation qui est présentement utilisée à la Banque. Premièrement, nous avons mis au point deux nouvelles mesures de l’activité étrangère (« MAE ») qui ajoutent de nouvelles composantes à la MAE qu’utilise la Banque. La première mesure ajoute les exportations et les dépenses publiques des États-Unis, et la seconde, la production industrielle américaine. Les coefficients de pondération affectés aux diverses composantes de chaque MAE sont calibrés d’après les données des tableaux internationaux des entrées-sorties pour 2014 afin d’éviter les problèmes d'instabilité qui se produisent lorsque ces coefficients sont estimés. Deuxièmement, nous avons inclus une nouvelle variable aux équations, la part tendancielle de la production manufacturière au Canada, afin de rendre compte des facteurs qui influent sur la part du Canada dans le marché mondial des importations, qu’il s’agisse de facteurs structurels ou de facteurs liés à la compétitivité. Troisièmement, le prix relatif des exportations est déterminé à partir d’un nouvel indice du taux de change effectif du dollar canadien construit par Barnett, Charbonneau et Poulin-Bellisle (2016). Dans l’ensemble, ces nouvelles équations améliorent l’adéquation statistique à l’intérieur de l’échantillon et offrent de meilleures prévisions hors échantillon comparativement à l’équation des exportations hors produits de base actuellement spécifiée dans le modèle « LENS » utilisé à la Banque.

description: Subtitle-- Recent breakthroughs in optical-based imaging in nonhuman primates promise to fundamentally advance our understanding of brain function and accelerate the development of next-generation brain-computer interfaces.Summary-- Two new studies demonstrate complementary approaches for imaging the activity patterns of large populations of neurons in nonhuman primates (NHPs).-- Bollimunta*, Santacruz* & colleagues used a head-mounted one-photon miniature microscope to image the activity of neurons deep in the motor cortex of a behaving macaque, and demonstrated the ability to perform offline decoding of the animal’s motor behavior using the same neurons tracked over weeks.-- Trautmann*, O’Shea*, Sun* & colleagues used two-photon microscopy to image the activity of neurons, also in the motor cortex, and show that it is possible to access deep cortical neurons by imaging their apical dendrites near the surface, allowing them to perform online, closed-loop decoding of the behaving macaque’s motor behavior sufficient to drive an optical brain-computer interface (BCI).-- Together, these studies pave the way for new experiments to understand how populations of neurons underlie behavior, and how new BCI technologies can treat neurological injury and disease.
Geometric Laws of Vortex Quantum Tunneling

Publisher: name: arXiv
Year: 1997
Subjects: subject: Condensed Matter (cond-mat)
subject: FOS: Physical sciences

description: In the semiclassical domain the exponent of vortex quantum tunneling is dominated by a volume which is associated with the path the vortex line traces out during its escape from the metastable well. We explicitly show the influence of geometrical quantities on this volume by describing point vortex motion in the presence of an ellipse. It is argued that for the semiclassical description to hold the introduction of an additional geometric constraint, the distance of closest approach, is required. This constraint implies that the semiclassical description of vortex nucleation by tunneling at a boundary is in general not possible. Geometry dependence of the tunneling volume provides a means to verify experimental observation of vortex quantum tunneling in the superfluid Helium II.

description: We study the percolation of FINITE-SIZED objects on two- and three-dimensional lattices. Our motivation stems, on one hand from some recent interesting experimental results on transport properties of impurity-doped oxide perovskites and on the other hand from the theoretical appeal that this problem presents. Our system exhibits a well-defined percolation threshold. We estimate the size of magnetic polarons, believed to be the carriers of the abovementioned transport. We have also obtained two critical exponents for our model, which characterize its universality class.

description: The Bank of Canada surveys Canadians to get a better understanding of how they pay for goods and services.

The Bank has conducted three Methods-of-Payment surveys—in 2009, 2013 and 2017. These surveys include a questionnaire and a diary where survey participants record their payments and cash withdrawals over the course of three days. Using this information, we calculate the share of payments made with cash, credit cards, debit cards and other methods.

Results from the 2017 survey show that cash use is declining. Cash makes up a smaller share of all transactions and a smaller share of the total amount spent. At the same time, Canadians are increasingly using contactless credit and debit cards and mobile and online payments, including Interac e-Transfer. We investigate the reasons for these patterns, such as demographics and perceptions. For the first time, the 2017 survey also explores the role of financial literacy and participants’ experiences with payment fraud.
description: La Banque du Canada sonde les Canadiens afin de mieux comprendre comment ils paient les biens et services qu’ils achètent.

Elle a mené trois enquêtes sur les modes de paiement – en 2009, 2013 et 2017. Ces enquêtes comprennent un questionnaire et un journal où les participants consignent leurs paiements et retraits d’argent sur une période de trois jours. Nous utilisons cette information pour calculer la part des paiements effectués au moyen d’argent comptant, de cartes de crédit, de cartes de débit et d’autres méthodes.

Les résultats de l’enquête de 2017 montrent que l’usage de l’argent comptant recule. Les espèces sont utilisées dans une plus petite part de toutes les transactions et représentent une plus petite proportion des sommes totales dépensées. Parallèlement, les Canadiens utilisent de plus en plus les cartes de crédit et de débit sans contact, de même que les paiements mobiles et en ligne, y compris les virements Interac. Nous étudions les raisons qui expliquent ces tendances, comme les facteurs démographiques et les perceptions. Pour la première fois, en 2017, l’enquête s’intéresse aussi au rôle des connaissances financières et aux fraudes en matière de paiements dont les participants ont été victimes.

description: This paper studies short-term forecasting of Canadian real GDP and its expenditure components using combinations of nowcasts from different models. Starting with a medium-sized data set, we use a suite of common nowcasting tools for quarterly real GDP and its expenditure components. Using a two-step combination procedure, the nowcasts are first combined within model classes and then merged into a single point forecast using simple performance-based weighting methods. We find that no single model clearly dominates over all forecast horizons, subsamples and target variables. This highlights that when operating in an uncertain environment, where the choice of model is not clear, combining forecasts is a prudent strategy.
description: Dans cette étude, nous examinons la prévision à court terme du produit intérieur brut (PIB) réel du Canada et de ses composantes de dépenses en combinant les prévisions pour la période en cours tirées de différents modèles. Nous appliquons une suite d’outils de prévision à un ensemble de données de taille moyenne afin de prévoir l’évolution du PIB réel trimestriel et de ses composantes de dépenses. À l’aide d’une méthode en deux étapes, nous combinons d’abord les prévisions effectuées pour le trimestre en cours avec des modèles d’une même catégorie, puis les prévisions combinées des différentes catégories pour aboutir à une seule prévision. Aux fins de combinaison, nous faisons appel à des méthodes simples de pondération selon l’exactitude antérieure des modèles. Nous constatons qu’aucun modèle particulier n’est nettement supérieur aux autres pour tous les horizons de prévision, toutes les sous-périodes et toutes les variables cibles. En conclusion, il est prudent de combiner les prévisions dans un contexte d’incertitude où le choix de modèle n’est pas évident.

description: In this paper, we extend the state-space methodology proposed by Blagrave et al. (2015) and decompose Canadian potential output into trend labour productivity and trend labour input. As in Blagrave et al. (2015), we include output growth and inflation expectations from consensus forecasts to help refine our estimates. Our alternative model, which we call the multivariate state-space framework (MSSF), adds to the Bank’s existing set of tools for estimating potential output and the output gap in Canada. We find that while the MSSF shares similar dynamics to the main approaches used by the Bank, it also indicates that the economy experienced greater excess supply in both the 1990 and 2008 recessions than the Bank’s other tools would suggest. Finally, the MSSF estimates that the Canadian economy has been operating close to capacity since the end of 2017.
description: Dans cette étude, nous élargissons le modèle espace d’états proposé par Blagrave et autres (2015) en décomposant la production potentielle du Canada en deux facteurs : la productivité tendancielle du travail et le facteur travail tendanciel. Comme dans l’étude citée, nous incluons des prévisions de Consensus Economics concernant la croissance de la production et l’inflation en vue d’affiner nos estimations. Notre modèle alternatif, à savoir le Cadre espace d’états multivarié, s’ajoute à la gamme d’outils qu’utilise la Banque pour estimer la production potentielle et l’écart de production au Canada. Nous constatons qu’en dépit d’une certaine dynamique qu’il partage avec les principales méthodes employées à la Banque, notre modèle indique que l’économie a connu, pendant les récessions de 1990 et de 2008, une offre excédentaire plus élevée que ne le donnaient à penser les autres outils de l’institution. Enfin, toujours selon notre modèle, l’économie canadienne tournerait près des limites de sa capacité depuis la fin de 2017.

But the fact that one of them (P00711137) bears the same label in Mez's hand as the “ holotype ” implies that the original material is composed of at least two distinct gatherings (from 1863 and 1865, respectively), making it necessary to designate a lectotype.

description: Ultra diffuse galaxies are a population of extended galaxies but with relatively low luminosities. The origin of these objects remains unclear, largely due to the observational challenges of the low surface brightness Universe. We present here a detailed stellar population analysis of a relatively isolated UDG, DGSAT I, based on spectroscopic data from the Keck Cosmic Web Imager integral field unit. The star formation history of DGSAT I seems to be extended, with a mean luminosity-weighted age of ~3 Gyr, in agreement with previous photometric studies. However, we find a very high [Mg/Fe] abundance ratio, which is extreme even in the context of the highly alpha-enhanced massive ellipticals and ultra-faint dwarfs. The [Mg/Fe]-enhancement of DGSAT I appears to be 10 times higher than the most magnesium-enhanced stellar systems discovered to date, and suggests that the chemical enrichment of this object was dominated by core-collapse supernovae. Intriguingly, this breaks the canonical relation between [Mg/Fe] and star formation time-scale. With a measured velocity dispersion of 56 +/- 10 km/s, DGSAT I also shows a high mass-to-light ratio, which indicates that it is highly dark matter-dominated. The metal-poor conditions of DGSAT I may have enhanced the formation of massive stars, while at the same time, additional mechanisms are needed to prevent iron-rich yields from being recycled into stars. These results suggest that some ultra-diffuse galaxies could have experienced chemical enrichment episodes similar to the first building blocks of galaxies.

title: Fundamental Drivers of Existing Home Sales in Canada
Creators: name: Webley, Taylor
Publisher: name: Bank of Canada

description: Existing home sales’ share of Canada’s economic pie has been rising in recent years, and variation around this trend has resulted in outsized contributions to changes in real gross domestic product (GDP). In this context, we use a cointegration framework to estimate the level of resale activity across the Canadian provinces that is supported by fundamentals—namely, full-time employment, housing affordability and migration flows—to help look through the volatility. The results suggest that, over longer horizons, resales activity and these fundamentals share a stable relationship, although deviations are sometimes persistent. We also find a robust and positive relationship between house price growth and deviations of existing home sales from fundamentals. While predicting quarterly changes in resales remains very difficult, provincial models improve upon national and naïve benchmarks and provide a useful framework for identifying risks to GDP growth that stem directly from the resale market.
description: Le poids des ventes de logements existants dans l’économie canadienne a augmenté ces dernières années, et la variation autour de cette tendance a eu pour conséquence que ces ventes ont contribué de manière démesurée aux mouvements du produit intérieur brut (PIB) réel. Dans ce contexte, nous utilisons des techniques de cointégration pour estimer, dans les provinces canadiennes, le niveau de l’activité de revente qui est soutenue par des facteurs fondamentaux – notamment l’emploi à temps plein, l’accessibilité à la propriété et les flux migratoires –, ce qui nous aide à faire abstraction de la volatilité. Les résultats donnent à penser qu’à plus long terme, l’activité de revente et ces facteurs ont une relation stable, même s’il arrive que des écarts persistent. Nous observons également une relation robuste et positive entre la croissance des prix des logements et les écarts des ventes de logements existants par rapport aux facteurs fondamentaux. Bien qu’il reste très difficile de prédire les variations trimestrielles des reventes, les modèles provinciaux permettent d’obtenir de meilleurs résultats que les modèles nationaux et naïfs, et ils offrent un cadre utile pour cerner les risques pesant sur la croissance du PIB qui sont directement attribuables au marché des reventes.

description: We investigate the scaling properties of the Barkhausen effect, recording the noise in several soft ferromagnetic materials: polycrystals with different grain sizes and amorphous alloys. We measure the Barkhausen avalanche distributions and determine the scaling exponents. In the limit of vanishing external field rate, we can group the samples in two distinct classes, characterized by exponents τ= 1.50 \pm 0.05 or τ= 1.27 \pm 0.03, for the avalanche size distributions. We interpret these results in terms of the depinning transition of domain walls and obtain an expression relating the cutoff of the distributions to the demagnetizing factor which is in quantitative agreement with experiments.

Image SNR comparison between the proposed sequence and 2D SASHA. The SNR was defined as signal (S) divided by standard deviation of noise (σ), in which the S was calculated as mean signal intensity of septum (red ROI on the weighted images), while σ was calculated from a ROI covering the left ventricle on the noise images. The unshown images (i.e. IMG3-IMG9) of 2D SASHA had SNR between that of IMG2 and IMG10. (DOCX 2258 kb)

description: Molecular motors in biological systems are expected to use ambient fluctuation. In a recent Letter [Phys. Rev. Lett. {\bf 80}, 5251 (1998)], it was showed that the following question was unsolved, ``Can thermal noise facilitate energy conversion by ratchet system?'' We consider it using stochastic energetics, and show that there exist systems where thermal noise helps the energy conversion.

description: This paper presents four blue-sky ideas for lowering the cost of the Government of Canada’s debt without increasing the debt’s risk profile. We argue that each idea would improve the secondary-market liquidity of government debt, thereby increasing the demand for government bonds and thus lowering their cost at issuance. The first two ideas would improve liquidity by enhancing the active management of the government’s debt through market operations used to support the liquidity of outstanding bonds. The second two ideas would simplify the set of securities issued by the government, concentrating issuance in a smaller set of bonds that would each be more highly traded. We discuss the ideas and give an account of the political, legal and operational impediments.
description: Cette étude présente quatre idées imaginatives visant à réduire le coût de la dette du gouvernement du Canada sans accroître le profil de risque de la dette. Nous soutenons que chacune d’entre elles permettrait d’améliorer la liquidité des titres d’emprunt du gouvernement sur le marché secondaire, et par le fait même de hausser la demande d’obligations d’État et de diminuer leur coût à l’émission. Les deux premières idées amélioreraient la liquidité en favorisant la gestion active de la dette publique au moyen des opérations de marché servant à assurer la liquidité des obligations en cours. Les deux autres idées simplifieraient l’ensemble de titres émis par le gouvernement en concentrant l’émission d’obligations dans un groupe restreint de titres qui seraient négociés en plus grands volumes. Nous analysons ces solutions et donnons un aperçu des contraintes présentes sur le plan politique, juridique et opérationnel.
Charge redistribution at Pd surfaces: ab initio grounds for tight-binding interatomic potentials

description: A simplified tight-binding description of the electronic structure is often necessary for complex studies of surfaces of transition metal compounds. This requires a self-consistent parametrization of the charge redistribution, which is not obvious for late transition series elements (such as Pd, Cu, Au), for which not only d but also s-p electrons have to be taken into account. We show here, with the help of an ab initio FP-LMTO approach, that for these elements the electronic charge is unchanged from bulk to the surface, not only per site but also per orbital. This implies different level shifts for each orbital in order to achieve this orbital neutrality rule. Our results invalidate any neutrality rule which would allow charge redistribution between orbitals to ensure a common rigid shift for all of them. Moreover, in the case of Pd, the power law which governs the variation of band energy with respect to coordination number, is found to differ significantly from the usual tight-binding square root.

description: We present a continuum model for a nematic elastomer network formed in a chiral environment, for instance in the presence of a chiral solvent. When this environment is removed, the network can retain some memory of its chiral genesis. We predict the residual chiral order parameter for a number of possible scenarios, and go on to examine the robustness (stability) of the imprinted chirality. We show that a twist-untwist transition can take place, which determines whether the imprinting has been successful. A transition is via a coarsening of the helical director pattern and a lengthening of its pitch. Finally, the effect due to a subsequent swelling by an achiral solvent, or by a solvent of differing chirality, is considered.
