description: Most data processing techniques, applied to biomedical and sociological time series, are only valid for random fluctuations that are stationary in time. Unfortunately, these data are often non stationary and the use of techniques of analysis resting on the stationary assumption can produce a wrong information on the scaling, and so on the complexity of the process under study. Herein, we test and compare two techniques for removing the non-stationary influences from computer generated time series, consisting of the superposition of a slow signal and a random fluctuation. The former is based on the method of wavelet decomposition, and the latter is a proposal of this paper, denoted by us as step detrending technique. We focus our attention on two cases, when the slow signal is a periodic function mimicking the influence of seasons, and when it is an aperiodic signal mimicking the influence of a population change (increase or decrease). For the purpose of computational simplicity the random fluctuation is taken to be uncorrelated. However, the detrending techniques here illustrated work also in the case when the random component is correlated. This expectation is fully confirmed by the sociological applications made in the companion paper. We also illustrate a new procedure to assess the existence of a genuine scaling, based on the adoption of diffusion entropy, multiscaling analysis and the direct assessment of scaling. Using artificial sequences, we show that the joint use of all these techniques yield the detection of the real scaling, and that this is independent of the technique used to detrend the original signal.

Publisher: name: Bank of Canada
Year: 2012

description: We investigate whether expectations that are not fully rational have the potential to explain the evolution of house prices and the price-to-rent ratio in the United States. First, a Lucas type asset-pricing model solved under rational expectations is used to derive a fundamental value for house prices and the price-rent ratio. Although the model can explain the sample average of the price-rent ratio, it does not generate the volatility and persistence observed in the data. Then, we consider an intrinsic bubble model and two models of extrapolative expectations developed by Lansing (2006, 2010) in applications to stock prices: one that features a constant extrapolation parameter and one in which the extrapolation coefficient depends on the dividend growth process. We show that these last two models are equally good at matching sample moments of the data. However, a counterfactual experiment shows that only the extrapolative expectation model with time-varying extrapolation coefficient is consistent with the run up in house prices observed over the 2000-2006 period and the subsequent sharp downturn.
description: Les auteures tentent de déterminer si l’évolution des prix des maisons et du ratio de ces prix aux loyers aux États-Unis peut s’expliquer par le fait que les anticipations ne soient pas entièrement rationnelles. Elles résolvent d’abord un modèle d’évaluation des actifs à la Lucas sous l’hypothèse de rationalité des anticipations afin d’obtenir une estimation du niveau fondamental des prix des maisons et du ratio prix/loyers. Même si le modèle parvient à restituer la moyenne empirique du ratio, il ne génère pas la volatilité et la persistance observées dans les données. Les auteures considèrent ensuite un modèle de bulle intrinsèque ainsi que deux modèles dotés d’anticipations extrapolatives mis au point par Lansing (2006 et 2010) pour l’analyse des cours en bourse : dans le premier, le coefficient d’extrapolation est constant, et dans le second, il dépend du processus de croissance des dividendes. Ces deux modèles réussissent pareillement à reproduire les moments empiriques. Toutefois, une simulation contrefactuelle montre que seul le modèle à coefficient d’extrapolation variable dans le temps cadre avec l’envolée des prix des maisons survenue entre 2000 et 2006 et leur forte chute subséquente.

description: Humans learn language by interaction with their environment and listening to other humans. It should also be possible for computational models to learn language directly from speech but so far most approaches require text. We improve on existing neural network approaches to create visually grounded embeddings for spoken utterances. Using a combination of a multi-layer GRU, importance sampling, cyclic learning rates, ensembling and vectorial self-attention our results show a remarkable increase in image-caption retrieval performance over previous work. Furthermore, we investigate which layers in the model learn to recognise words in the input. We find that deeper network layers are better at encoding word presence, although the final layer has slightly lower performance. This shows that our visually grounded sentence encoder learns to recognise words from the input even though it is not explicitly trained for word recognition.

description: We examine the evolution of the effects of monetary policy shocks on the distribution of disaggregate prices and quantities of personal consumption expenditures to assess the contribution of monetary policy to changes in U.S. inflation dynamics. Given that the transmission of monetary policy to aggregate inflation is determined by the responses of its underlying components, the degree of monetary non-neutrality is ultimately the result of relative price effects at the sectoral level. We provide evidence of considerable heterogeneity in sectoral price responses by introducing time variation in a factor-augmented vector autoregression model. Over time the majority of individual prices respond negatively after a contractionary monetary policy shock and the price dispersion diminishes. We link these empirical findings to a multi-sector DSGE model and show that they are consistent with firms’ heterogeneous pricing decisions and changes in the importance of the cost channel of monetary policy and the degree of wage flexibility.
description: Les auteurs examinent l’évolution de l’incidence des chocs de politique monétaire sur la distribution des prix individuels et des volumes de consommation des ménages afin d’évaluer comment la politique monétaire influe sur la dynamique de l’inflation aux États-Unis. Comme la réaction de l’inflation globale aux chocs de politique monétaire est déterminée par celle de ses composantes sous-jacentes, le degré de non-neutralité monétaire résulte au bout du compte des effets de prix relatifs au niveau sectoriel. Les auteurs constatent une forte hétérogénéité des comportements de prix entre secteurs lorsqu’ils utilisent un modèle FAVAR à coefficients variables dans le temps. La majorité des prix diminuent après un choc de politique monétaire négatif et la dispersion des prix s’atténue. Les auteurs lient ces résultats empiriques à un modèle d’équilibre général dynamique et stochastique multisectoriel et montrent que ceux-ci cadrent avec l’hétérogénéité des décisions de prix des entreprises et les variations de l’importance du canal du coût marginal de production et du degré de flexibilité des salaires.

description: Many predict that innovations in retail payment may render cash obsolete. We investigate this possibility in the context of recent payment innovations such as contactless-credit and stored-value cards. We apply causal inference methods on the 2009 Bank of Canada Method of Payment survey, a representative sample of adult Canadians’ shopping behaviour for retail consumption over a three-day period. We find that using contactless credit cards and stored-value cards lead to a reduction in average cash usage for transactions both in terms of value and volume. Sensitivity analysis is undertaken and our estimates are robust to hidden bias.

Nous étudions cette possibilité dans le contexte de récentes innovations comme la carte de crédit sans contact et la carte prépayée. À l’aide de méthodes d’inférence causale appliquées à l’enquête sur les modes de paiement menée par la Banque du Canada en 2009, nous étudions le comportement d’un échantillon représentatif d’adultes canadiens en matière de paiement de détail sur une période de trois jours. Nous montrons que le recours à la carte de crédit sans contact et à la carte prépayée se solde par une diminution de l’utilisation moyenne des espèces pour le règlement des transactions, à la fois en valeur et en volume. Une analyse de sensibilité confirme la robustesse de nos estimations à la présence éventuelle de biais cachés.

C-RPNs: Promoting Object Detection in real world via a Cascade Structure of Region Proposal Networks

description: Recently, significant progresses have been made in object detection on common benchmarks (i.e., Pascal VOC). However, object detection in real world is still challenging due to the serious data imbalance. Images in real world are dominated by easy samples like the wide range of background and some easily recognizable objects, for example. Although two-stage detectors like Faster R-CNN achieved big successes in object detection due to the strategy of extracting region proposals by region proposal network, they show their poor adaption in real-world object detection as a result of without considering mining hard samples during extracting region proposals. To address this issue, we propose a Cascade framework of Region Proposal Networks, referred to as C-RPNs. The essence of C-RPNs is adopting multiple stages to mine hard samples while extracting region proposals and learn stronger classifiers. Meanwhile, a feature chain and a score chain are proposed to help learning more discriminative representations for proposals. Moreover, a loss function of cascade stages is designed to train cascade classifiers through backpropagation. Our proposed method has been evaluated on Pascal VOC and several challenging datasets like BSBDV 2017, CityPersons, etc. Our method achieves competitive results compared with the current state-of-the-arts and all-sided improvements in error analysis, validating its efficacy for detection in real world.

Publisher: name: Challenging Glass Conference Proceedings
Year: 2018

description: The Opus project was designed by Zaha Hadid Architects, for Omniyat in Dubai. It is a 20 story fully glazed building, resembling a cube with the core melted out. The outer flat facades are neutral transparent glazed with silver mirror pattern, while the core area is dark blue 3D formed glazing. To achieve this vision, several glass processing technologies were studied, selected, specified – and some abandoned after further studies. The project implemented several newly developed technologies, pushing the limits of the industry. Challenges included achieving the 3D double curved shape, achieving the color, achieving adequate performance for Dubai climate, dealing with the radiation focusing effect the geometry imposes, ensure seamless visual appearance among different support systems – roof, wall, soffit- , procure special materials in sufficient quantities in reasonable time and keeping the project affordable. The presentation will give a summary of the project’s technical development.

title: Estimating the Demand for Settlement Balances in the Canadian Large Value Transfer System
Creators: name: Zhang, Nellie
Publisher: name: Bank of Canada
Year: 2012

description: This paper applies a static model of an interest rate corridor to the Canadian data, and estimates the aggregate demand for central-bank settlement balances in the Large Value Transfer System (LVTS). The empirical specification controls for various calendar effects that have been shown to cause fluctuations in LVTS payment flows. The analysis takes into account the downward divergence of the overnight interest rate from the target rate, which has been persistent since 2005. The results suggest that a target of $3 billion for LVTS settlement balances does not seem excessive during the time period when Canadian monetary policy was operating at the effective lower bound (ELB). Specifically, the model projects that, if the consistent downward divergence of overnight interest rate is taken into account, then on average $2.405 billion of LVTS settlement balances would probably have been sufficient to achieve the goal of keeping the overnight interest rate at or very close to the lower bound of the corridor. However, by targeting a slightly higher level, the Bank of Canada could be 95% certain that the overnight interest rate would on average not exceed its policy rate at the lower bound of the corridor. In addition, the estimation shows that the point elasticity of overnight interest rate is around 0.17 when the daily level of settlement balances is targeted at $3 billion under the ELB framework.
description: L’auteure applique aux données canadiennes un modèle statique formalisant un corridor de taux d’intérêt en vue d’estimer la demande totale de soldes de règlement au sein du Système de transfert de paiements de grande valeur (STPGV). La spécification empirique retenue neutralise différents effets de calendrier reconnus à l’origine de fluctuations dans les flux de paiement du STPGV. L’analyse tient compte de la divergence à la baisse du taux du financement à un jour qu’on observe depuis 2005 par rapport au taux visé. D’après les résultats obtenus, un niveau cible de 3 milliards de dollars pour les soldes de règlement durant la période où le taux directeur au Canada se situait à sa valeur plancher ne paraît pas excessif. Plus précisément, si l’on considère la divergence à la baisse persistante du taux à un jour, des soldes moyens de 2,405 milliards de dollars auraient probablement été suffisants, selon le modèle, pour que le taux à un jour se maintienne à la limite inférieure du corridor ou très près de celle-ci. Toutefois, en visant un montant légèrement supérieur, la Banque du Canada pouvait être sûre à 95 % que le taux à un jour ne dépasserait pas, en moyenne, le taux directeur (la limite inférieure du corridor). L’estimation montre en outre que l’élasticité du taux à un jour s’établit à environ 0,17 quand le niveau quotidien visé pour les soldes de règlement est de 3 milliards de dollars et que le taux directeur se trouve à sa valeur plancher.

description: This paper visualizes and analyses demographic and socio-economic changes in a local labour market perspective. The territorial context is a part of the sparsely populated northern coastal area of Sweden, representing a wide range of differences in conditions and development patterns. The area is divided into two local labour markets with a highway as the main connecting link The study puts attention on processes of change between 1990 and 2002. The analysis is based on georeferenced data with a high spatial resolution and to personal attributes linked to each inhabitant. The paper illustrates spatial structures and processes of change in terms of population, employment, and people with a higher education. In particular, the different development patterns within urban and rural parts of the area, where we find strongly contrasting growing and declining settlements, is discussed in relation to theoretical notions on the role of social capital and creative class. The concluding part is devoted to a discussion of future perspectives for the different parts of the area and appropriate planning approaches.

description: We study the specific dependence of the periodic Anderson Model (PAM) in the limit of $U=\infty$ employing the X-boson treatment in two fifferent regimes of the PAM: the heavy fermion Kondo (HF-K) and the heavy fermion local magnetic regime (HF-LMM). We obtain a multiple peak structure for the specific heat in agreement with experimental results as well as the increase of the electronic effective mass at low temperatures associated with the HF-K regime. The entropy per site at low T tends to zero in the HF-K regime, corresponding to a singlet ground state, and it tends to $k_{B}ln(2)$ in the HF-LMM, corresponding to a doublet ground state at each site. The linear coefficient $γ(T)=C_{v}/T$ of the specific heat qualitatively agrees with the experimental results obtained for differents materials in the two regimes considered here.

description: We introduce a deterministic SO(3) invariant dynamics of classical spins on a discrete space-time lattice and prove its complete integrability by explicitly finding a related non-constant (baxterized) solution of the set-theoretic quantum Yang-Baxter equation over the 2-sphere. Equipping the algebraic structure with the corresponding Lax operator we derive an infinite sequence of conserved quantities with local densities. The dynamics depend on a single continuous spectral parameter and reduce to a (lattice) Landau-Lifshitz model in the limit of a small parameter which corresponds to the continuous time limit. Using quasi-exact numerical simulations of deterministic dynamics and Monte Carlo sampling of initial conditions corresponding to a maximum entropy equilibrium state we determine spin-spin spatio-temporal (dynamical) correlation functions with relative accuracy of three orders of magnitude. We demonstrate that in the equilibrium state with a vanishing total magnetization the correlation function precisely follow Kardar-Parisi-Zhang scaling hence the spin transport belongs to the universality class with dynamical exponent z=3/2, in accordance to recent related simulations in discrete and continuous time quantum Heisenberg spin 1/2 chains.

description: At the beginning we delimited agricultural areas. Then we compared the picture obtained with the spatial diversity of human capital. The analysis of human capital was based on three groups of measures. They are related to investments on human capital, its resources and effectiveness of its application, successively. The results show that agricultural areas are rather those one with the lowest level of human capital index. The core-periphery scheme reveals. Evidently developed core-periphery scheme has serious consequences. On one hand establishment of megalopolises rich in human capital should enable them successful competition at international stage. On the other hand establishment of strong centres at the costs of peripheral -agricultural areas is a serious problem. Great differences that appear between large towns and the rest of the country may get deeper as long as there are no development impulses from the centre to peripheries.

A Glass Pavilion

description: In January 2015 a pavilion mainly built of glass was finished. The building contractors themselves planned it as a transparent extension of their detached house to the garden. The structural system consists on one hand of a glazed steel frame with four stanchions rigidly fixed to the base plate and connected by four transoms at the top and on the other hand of two laterally glass attachments. These are made of vertical load-bearing glass walls and a horizontal glass roof, which are connected among each other by structural sealants. Together with an anchor profile that is completely hidden in the joint gap, the glass elements are also acting as bracing elements. Specifications of the building authorities called for a structural concept of the pavilion’s glass attachments for different states of destruction. In addition extensive requirements had to be fulfilled to obtain a special building permit for the structural sealants. The project is an outstanding example for the possibilities in constructing with glass. It combines the structural features of a load bearing all glass building with state-of-the-art joint techniques.

description: We examine the relative ability of simple inflation targeting (IT) and price level targeting (PLT) monetary policy rules to minimize both inflation variability and business cycle fluctuations in Canada for shocks that have important consequences for global commodity prices. We find that commodities can play a key role in affecting the relative merits of the alternative monetary policy frameworks. In particular, large real adjustment costs in energy supply and demand induce highly persistent cost-push pressures in the economy leading to a significant deterioration in the inflation – output gap trade-off available to central banks, particularly to those pursuing price level targeting.
description: Les auteurs examinent la capacité relative de règles simples de ciblage de l’inflation et de ciblage du niveau des prix à minimiser tant la variabilité de l’inflation que les fluctuations économiques au Canada lorsque les chocs subis ont d’importantes retombées sur les cours mondiaux des produits de base. Ils constatent que ces derniers peuvent jouer un rôle déterminant dans les mérites relatifs de ces deux types de règles de politique monétaire. En particulier, des coûts d’ajustement réels considérables de l’offre et de la demande d’énergie engendrent des pressions très persistantes sur les coûts et donc sur l’inflation. Ces pressions entraînent une nette détérioration de l’arbitrage entre l’inflation et l’écart de production, surtout pour les banques centrales qui poursuivent une cible de niveau des prix.

description: In the present work, bagasse hemicelluloses were crosslinked using citric acid as a nontoxic crosslinking agent to improve the wet strength of hemicelluloses/SPI composite films at moderate relative humidity (RH). Fourier transform infrared and thermal analysis confirmed the formation of ester crosslinks between hemicelluloses and citric acid and led to lower the degradation temperature. The wet tensile strength properties of the citric acid crosslinked hemicelluloses/SPI films in 50 − 95% RH was improved significantly, compared to the uncross-linked films. Particularly, the results indicated that the films crosslinked under 0.44 degrees of substitution showed the best comprehensive properties among all films. However, excessive addition of citric acid in the composite films might decrease the compatibility of the films and have negative effects on their performance. This study provides an effective pathway for preparation of hemicelluloses/SPI composite films with improved wet strength properties, which have a potential as packaging material for food application.

description: In collision-poor plasmas from space, e.g., solar wind or stellar outflows, the heat-flux carried by the strahl or beaming electrons is expected to be regulated by the self-generated instabilities. Recently, simultaneous field and particle observations have indeed revealed enhanced whistler-like fluctuations in the presence of counter-beaming populations of electrons, connecting these fluctuations to the whistler heat-flux instability (WHFI). This instability is predicted only for limited conditions of electron beam-plasmas, and was not captured in numerical simulations yet. In this letter we report the first simulations of WHFI in particle-in-cell (PIC) setups, realistic for the solar wind conditions, and without temperature gradients or anisotropies to trigger the instability in the initiation phase. The velocity distributions have a complex reaction to the enhanced whistler fluctuations conditioning the instability saturation by a decrease of the relative drifts combined with induced (effective) temperature anisotropies (heating the core electrons and pitch-angle and energy scattering the strahl). These results are in good agreement with a recent quasilinear approach, and support therefore a largely accepted belief that WHFI saturates at moderate amplitudes. In anti-sunward direction the strahl becomes skewed with a pitch-angle distribution decreasing in width as electron energy increases, that seems to be characteristic to self-generated whistlers and not to small-scale turbulence.

description: The effect of perturbative QCD interactions on the high energy scattering of electroweak vector bosons, when the exchanged channel has pion quantum numbers, is considered. The chiral anomaly is shown to appear in the couplings of particular transverse momentum diagrams, producing an enhancement of the scattering amplitude by a power of the energy. At $O(α_s)$ a single large transverse momentum gluon is involved and, within the transverse momentum diagram framework, there is no cancelation. In higher orders, soft gluons, carrying both normal and anomalous color parity, are also present. The manipulation of a transverse momentum cut-off to replace the ultra-violet anomaly divergence by infra-red divergences that can lead to confinement and chiral symmetry breaking is briefly discussed. Possible implications for electroweak symmetry breaking are noted.

description: We propose investigating optimal subsampling for functional regression with massive datasets based on the mode value, which is referred to as functional quasi-mode regression, to reduce data volume and alleviate computational burden. Using data-adaptive weights derived from regression residuals, the suggested regression offers enhanced robustness against nonnormal errors compared to traditional least squares or maximum likelihood estimation methods. To estimate the model, we employ B-spline basis functions to approximate the functional coefficient and include a penalty term in the objective function for enforcing smoothness in the resulting estimator. We adopt a computationally efficient mode-expectation-maximization algorithm, augmented by a Gaussian kernel, for numerical estimation. Under mild regularity conditions, we derive the asymptotic distributions of both full data and subsample quasi-mode estimators. The optimal subsampling probabilities by minimizing the asymptotic variance-covariance matrix under A- and L-optimality criteria are identified. These optimal probabilities rely on the full data estimate, prompting the development of a two-step algorithm to approximate the optimal subsampling procedure. The resultant algorithm is processing-efficient and can significantly reduce computational time compared to the full data approach. We also establish the asymptotic normality of the quasi-mode estimator obtained through this two-step algorithm. To assess finite sample performance, we conduct Monte Carlo simulations and analyze air quality data, showcasing the effectiveness of the developed estimator. Supplemental materials for this article are available online.

description: The presence of bio-macromolecules as major ingredients is a primary factor in marketing many biologically derived macromolecular supplements. Workflows for analyzing these supplements for quality assurance, adulteration, and other supply-chain difficulties must include a qualitative assessment of small-molecule and macromolecular components; however, no such integrated protocol has been reported for these bio-macromolecular supplements. Twenty whey protein supplements were analyzed using an integrated workflow to identify protein content, protein adulteration, inorganic elemental content, and macromolecular and small-molecule profiles. Orthogonal analytical methods were employed, including NMR profiling, LC-DAD-QToF analysis of small-molecule components, ICP-MS analysis of inorganic elements, determination of total protein content by a Bradford assay, SDS-PAGE protein profiling, and bottom-up shotgun proteomic analysis using LC-MS-MS. All 20 supplements showed a reduced protein content compared to the claimed content but no evidence of adulteration with protein from an unclaimed source. Many supplements included unlabeled small-molecule additives (but nontoxic) and significant deviations in metal content, highlighting the importance of both macromolecular and small-molecule analysis in the comprehensive profiling of macromolecular supplements. An orthogonal, integrated workflow allowed the detection of crucial product characteristics that would have remained unidentified using traditional workflows involving either analysis of small-molecule nutritional supplements or protein analysis.
The galactic evolution of the supernova rates

description: Supernova rates (hypernova, type II, type Ib/c and type Ia) in a particular galaxy depend on the metallicity (i.e. on the galaxy age), on the physics of star formation and on the binary population. In order to study the time evolution of the galactic supernova rates, we use our chemical evolutionary model that accounts in detail for the evolution of single stars and binaries. In particular, supernovae of type Ia are considered to arise from exploding white dwarfs in interacting binaries and we adopt the two most plausible physical models: the single degenerate model and the double degenerate model. Comparison between theoretical prediction and observations of supernova rates in different types of galaxies allows to put constraints on the population of intermediate mass and massive close binaries. The temporal evolution of the absolute galactic rates of different types of SNe (including the SN Ia rate) is presented in such a way that the results can be directly implemented into a galactic chemical evolutionary model. Particularly for SNIa the inclusion of binary evolution leads to results considerably different from those in earlier population synthesis approaches, in which binary evolution was not included in detail.

description: In the era of the information society, the existence and quality of the rural municipality's own website is an important factor of its competitiveness. Therefore, the state or regional governments sometimes support the construction of municipality websites. This process is just starting and the utilization of these websites for competitive aims is rather problematic. On the other hand, there are many rural municipality's own websites that are typical products of the enthusiasm of local people and represent the "bottom-up " approach. These websites are very often oriented on improving of the municipality image and competitiveness by the description of the municipality's strengths. The main aim of this paper is identification of existing websites of rural municipalities in Slovakia. We study the spatial distribution of rural municipalities with their own website and formulate the explanation of registered spatial differentiation by the settlement structure and regional economic performance. The next step is the content analysis of websites with special regard to the elements, which increase the competitiveness of rural municipality for three groups of their potential actors: immigrants, investors (entrepreneurs) and tourists.
title: On the Existence and Fragility of Repo Markets
Creators: name: Tomura, Hajime
Publisher: name: Bank of Canada

description: This paper presents a model of an over-the-counter bond market in which bond dealers and cash investors arrange repurchase agreements (repos) endogenously. If cash investors buy bonds to store their cash, then they suffer an endogenous bond-liquidation cost because they must sell their bonds before the scheduled times of their cash payments. This cost provides incentive for both dealers and cash investors to arrange repos with endogenous margins. As part of multiple equilibria, the bond-liquidation cost also gives rise to another equilibrium in which cash investors stop transacting with dealers all at once. Credit market interventions block this equilibrium.
description: L’auteur présente le modèle d’un marché obligataire de gré à gré sur lequel des investisseurs disposant de liquidités et des courtiers concluent de façon endogène des opérations de pension. Si les investisseurs achètent des obligations pour y conserver leurs liquidités, ils s’exposent à un coût de liquidation, car ils seront forcés de les vendre avant l’échéance des paiements qu’ils doivent régler comptant. Ce coût endogène incite tant les courtiers que les acquéreurs d’obligations à conclure des pensions assorties de marges endogènes. Le coût de liquidation des obligations permet l’apparition d’un second équilibre, dans lequel tous les investisseurs cessent en même temps de traiter avec les courtiers. Cet équilibre est entravé par des interventions sur les marchés de crédit.
