description: When gravity couples to scalar fields in Anti-de Sitter space, the geometry becomes non-AdS and develops singularities generally. We propose a criterion that the singularity is physically admissible if the integral of the on-shell Lagrangian density over the finite range is finite everywhere. For all classes of the singularities studied here, the criterion suggested in this paper coincides with an independent proposal made by Gubser that the potential should be bounded from above in the solution. This gives a reason why Gubser's conjecture works.

10^20 eV Cosmic Ray and Particle Physics with IceCube

description: We show that a kilometer-scale neutrino observatory, though optimized for detecting neutrinos of TeV to PeV energy, can reveal the science associated with the enigmatic super-EeV radiation in the Universe. Speculations regarding its origin include heavy relics from the early Universe, particle interactions associated with the Greisen cutoff, and topological defects which are remnant cosmic structures associated with phase transitions in grand unified gauge theories. We show that it is a misconception that new instruments optimized to EeV energy can exclusively do this important science. Because kilometer-scale neutrino telescopes such as IceCube can reject the atmospheric neutrino background by identifying the very high energy of the signal events, they have sensitivity over the full solid angle, including the horizon where most of the signal is concentrated. This is critical because upgoing neutrino-induced muons, considered in previous calculations, are absorbed by the Earth. Previous calculations have underestimated the event rates of IceCube for EeV signals by over one order of magnitude.

description: Background: Widespread adoption of electronic health records (EHRs) has enabled secondary use of EHR data for clinical research and healthcare delivery. Natural language processing (NLP) techniques have shown promise in their capability to extract the embedded information in unstructured clinical data, and information retrieval (IR) techniques provide flexible and scalable solutions that can augment the NLP systems for retrieving and ranking relevant records. Methods: In this paper, we present the implementation of Cohort Retrieval Enhanced by Analysis of Text from EHRs (CREATE), a cohort retrieval system that can execute textual cohort selection queries on both structured and unstructured EHR data. CREATE is a proof-of-concept system that leverages a combination of structured queries and IR techniques on NLP results to improve cohort retrieval performance while adopting the Observational Medical Outcomes Partnership (OMOP) Common Data Model (CDM) to enhance model portability. The NLP component empowered by cTAKES is used to extract CDM concepts from textual queries. We design a hierarchical index in Elasticsearch to support CDM concept search utilizing IR techniques and frameworks. Results: Our case study on 5 cohort identification queries evaluated using the IR metric, P@5 (Precision at 5) at both the patient-level and document-level, demonstrates that CREATE achieves an average P@5 of 0.90, which outperforms systems using only structured data or only unstructured data with average P@5s of 0.54 and 0.74, respectively.

description: We report the synthesis and characterization of Nd_{0.5}Sr_{0.5}MnO_{3} thin films grown by the Pulsed Laser Deposition technique on 100 -oriented LaAlO_{3} substrates. X-ray diffraction (XRD) studies show that the films are 101 -oriented, with a strained and quasi-relaxed component, the latter increasing with film thickness. We observe that transport properties are strongly dependent on the thickness of the films. Variable temperature XRD down to 100 K suggests that this is caused by substrate induced strain on the films.

Subjects: subject: Pattern Formation and Solitons (nlin.PS)

description: Topological solitons can propagate without radiation in discrete media. These solutions are known as embedded solitons (ES). They come as isolated solutions and exist despite their resonance with the linear spectrum of the respective lattices. In this paper the properties of embedded solitons in the discrete double sine-Gordon equation with the next-neighbor and second-neighbor interactions are investigated. Depending on the sign of these interactions they can be either destructive or favorable for the ES creation. The ES existence area depends on the width of the linear spectrum: narrowing of the spectrum widens the ES existence range and vice versa. The application to the Josephson junction arrays is discussed.

description: Microcavity inhomogeneous line widths are calculated numerically using a microscopic two dimensional model of the polariton interaction with quantum well disorder. The calculations show show that in most structures the line widths are determined by disorder scattering between polariton and exciton states. This is because motional narrowing effectively removes the contribution due to multiple scattering between polariton states.

description: This paper introduces new weighting schemes for model averaging when one is interested in combining discrete forecasts from competing Markov-switching models. In particular, we extend two existing classes of combination schemes – Bayesian (static) model averaging and dynamic model averaging – so as to explicitly reflect the objective of forecasting a discrete outcome. Both simulation and empirical exercises show that our new combination schemes outperform competing combination schemes in terms of forecasting accuracy. In the empirical application, we estimate and forecast U.S. business cycle turning points with state-level employment data. We find that forecasts obtained with our best combination scheme provide timely updates of the U.S. business cycles.
description: Les auteurs présentent de nouvelles méthodes de pondération pour la combinaison de prévisions de variables discrètes issues de différents modèles de Markov à changement de régime. Plus particulièrement, ils étendent deux classes existantes de méthodes de combinaison – combinaison de prévisions établies au moyen de modèles bayésiens (statiques) et combinaison dynamique de prévisions – de manière à correspondre explicitement à l’objectif assigné à l’exercice de prévision d’une variable discrète. Les simulations et l’application empirique montrent qu’en ce qui a trait à l’exactitude des prévisions, les nouvelles méthodes de combinaison surclassent les méthodes de combinaison concurrentes. S’agissant de l’application empirique, les auteurs estiment et prévoient les points de retournement du cycle de l’économie américaine à l’aide de données sur l’emploi provenant des États. Ils constatent que les prévisions obtenues à partir de leur meilleure méthode de combinaison fournissent des renseignements en temps opportun sur les cycles économiques aux États-Unis.

description: This paper analyzes the macroeconomic impact of oil shocks in four of the largest oil-consuming Asian economies, using a structural vector autoregressive model. We identify three different types of oil shocks via sign restrictions: an oil supply shock, an oil demand shock driven by global economic activity and an oil-specific demand shock. The main results suggest that economic activity and prices respond very differently to oil price shocks depending on their type. In addition, a country’s oil-importing and -exporting status in the world oil market affects the transmission of shocks. Finally, subsample analysis shows a possible structural break in Japan and South Korea for all three types of oil shocks.
description: À l’aide d’un modèle vectoriel autorégressif structurel, les auteurs analysent l’incidence macroéconomique des chocs pétroliers dans quatre des économies asiatiques les plus consommatrices de pétrole. S’appuyant sur des restrictions de signe, ils distinguent trois types de chocs, à savoir un choc d’offre, un choc de demande créé par l’activité économique mondiale et un choc spécifique de demande. Les principaux résultats indiquent que l’activité économique et les prix réagissent de manière très différente aux variations des cours du pétrole selon le type de choc en cause. Par ailleurs, le statut d’importateur ou d’exportateur de pétrole d’un pays au sein du marché mondial des produits pétroliers influe sur la transmission des chocs. Enfin, l’analyse par sous-échantillons montre un possible changement structurel au Japon et en Corée du Sud relativement aux trois classes de chocs recensées.

description: One of the great triumphs of the inflationary model is the prediction of the flat power spectrum of the CMB fluctuation. The prediction is based on the assumption of the de-Sitter vacuum in the past infinity. However, the true past infinity of the inflation is expected to be dominated by radiation and curvature of the space. We consider pre-inflation era as dominated by radiation and curvatures as well as inflation potential. We derive the exact solutions for the scalar fields in this era and find a exact power spectra caused by the inflaton vacuum fluctuation. We show that the power spectrum is almost flat for sub-horizon scale and deviates from flat for very high super-horizon fluctuation, which is quite sensitive to the radiation and the curvature in the pre-inflation era.

Errors and disturbances and the performance of some common income distribution functions

Publisher: name: Unknown
Year: 1980
Subjects: Research Methods/ Statistical Methods

description: Recent papers by Kloek & van Dijk and by McDonald & Ransom report maximum likelihood estimates cE various income distribution functions and provide test statistics of goodness of fit. According to the latter virtually all models should be rejected, yet this conclusion is avoided, and rightly so for the test is too strict. It allows for sampling variation only, while in fact income distribution functions like any other econometric model are not expected to hold exactly. If this is so one should allow for the presence of errors and disturbances in analysing income distribution data. The simplest approach is to treat observed income as the sum of a systematic component which follows some specific distribution and an independent normal error. We apply this model to three traditional two-parameter functions, viz. the Pareto, Gamma and Lognormal distribution. Since maximum likelihood estimation is impracticable we proceed by the method of moments. The evidence of a few data sets suggests that the Pareto nor the Gamma distribution are redeemed by the introduction of an error term. The verdict on the Lognormal must be postponed; as a by-product of the analysis we find that it does rather better than was suggested some years ago by Salem & Mount. A major difficulty is that estimation by moments turns out to be a delicate operation when higher moments are involved, especially if income class frequency data must be used.

O evento que deu origem a este trabalho ocorreu em novembro/2023 e seu objetivo foi o de promover um espaço de aprendizagem e troca de experiências sobre estratégias de cuidado nas instituições de ensino superior, refletindo sobre a vida como valor maior para além da academia e realizando discussões sobre ações preventivas de promoção de saúde e qualidade de vida.

Como diria Merleau-Ponty, “para ver o mundo e apreendê-lo como paradoxo, é preciso romper nossa familiaridade com ele"; portanto, acreditamos que esses capítulos são substancialmente relevantes para que o leitor possa não apenas refletir sobre as implicações dos nossos modos atuais de viver, conviver e sobreviver nas instituições de ensino superior no Brasil, mas também sobre as possibilidades de cuidado nesses contextos, e, principalmente, se disponibilizar a mudar essa realidade, já que as transformações sociais são responsabilidade de todos nós, assim como o cuidado, para se possibilitar uma vida com sentido nessa lida diária que é a existência humana.
title: Sheltered Income: Estimating Income Under-Reporting in Canada, 1998 and 2004
Creators: name: Dunbar, Geoffrey

Publisher: name: Bank of Canada
Year: 2015

description: We use data from the Survey of Financial Security and the Survey of Household Spending to estimate the incidence and extent of income under-reporting in Canada in 1998 and 2004. We estimate that the proportion of households under-reporting income is roughly 35 to 50 per cent in both years. Our estimates also suggest that the amount of under-reported income rose by roughly 40 per cent between 1998 and 2004 and remained stable as a proportion of GDP of 14 to 19 per cent. We find evidence that income underreporting is pervasive and is not confined to households that report self-employment income in the survey data. We also find that poverty measures that rely on reported income appear unreliable because under-reporting necessarily implies a lower reported income. Thus, households that under-report appear to be poorer. We propose a simple ratio method of identifying households that under-report income using the household’s budget share on shelter.
description: Les auteurs utilisent des données de l’Enquête sur la sécurité financière et de l’Enquête sur les dépenses des ménages pour mesurer l’incidence et l’ampleur de la sousdéclaration des revenus au Canada en 1998 et en 2004. Ils estiment que la proportion des ménages déclarant des revenus inférieurs à ceux qu’ils perçoivent réellement se situe, en gros, entre 35 et 50 % pour ces deux années. De plus, selon leurs estimations, la valeur totale des revenus sous-déclarés s’est accrue de quelque 40 % entre 1998 et 2004, et elle est demeurée stable en proportion du PIB, soit entre 14 et 19 %. Les auteurs constatent que la sous-déclaration des revenus est très répandue et qu’elle ne se limite pas aux ménages qui, selon les données des enquêtes, déclarent des revenus d’un travail indépendant. Ils soulèvent également des doutes quant à la fiabilité des statistiques sur la pauvreté établies à partir du revenu déclaré, étant donné que les ménages qui sousdéclarent leurs revenus paraissent nécessairement plus pauvres. Les auteurs proposent une méthode simple fondée sur des ratios pour déterminer quels ménages sous-déclarent leurs revenus, en s’appuyant sur la part du budget consacrée au logement.

Publisher: name: Bank of Canada
Year: 2015

description: Prices of commodities, including metals, energy and agricultural products, rose markedly over the 2009–2010 period. Some observers have attributed a significant part of this increase in commodity prices to the U.S. Federal Reserve’s large-scale asset purchase (LSAP) programs. Using event-study methodologies, this paper investigates whether the announcement and subsequent implementation of the Fed’s LSAPs, and communication of the tapering of these purchases, affected commodity prices. Our empirical results suggest that LSAP announcements did not lead to higher commodity prices. However, there is some evidence that the currencies of commodity exporters appreciated and that their stock markets posted gains. The results suggest that other factors, such as supply constraints and robust demand from emerging-market economies, were the likely drivers behind the increase in commodity prices. Last, the paper finds that commodity prices have become more sensitive to macroeconomic news when monetary policy is at the effective lower bound.
description: Les cours des matières premières, dont les métaux, l’énergie et les produits agricoles, ont connu une forte hausse entre 2009 et 2010. Certains observateurs ont attribué une part importante de cette augmentation aux programmes d’achat massif d’actifs pilotés par la Réserve fédérale américaine. L’objet de notre étude est d’évaluer, au moyen de méthodes appliquées aux études événementielles, si les cours des matières premières ont été influencés par l’annonce et la mise en oeuvre de ces programmes, ainsi que par l’annonce de la normalisation du rythme d’achat des actifs. Au vu des résultats empiriques, tout porte à croire que les annonces n’ont pas entraîné de renchérissement des matières premières. Il y a néanmoins lieu de penser que les devises des exportateurs de matières premières se sont appréciées, et que les marchés boursiers ont enregistré des gains. D’autres facteurs, qu’il s’agisse de contraintes liées à l’offre ou de la demande robuste des pays émergents, auraient donc fait monter les prix des matières premières. Enfin, les prix des matières premières sont plus sensibles aux nouvelles macroéconomiques depuis que le taux directeur se situe à sa valeur plancher.

description: In this work we investigate properties of fermions in the SO(5) theory of high Tc superconductivity. We show that the adiabatic time evolution of a SO(5) superspin vector leads to a non-Abelian SU(2) holonomy of the SO(5) spinor states. Physically, this non-trivial holonomy arises from the non-zero overlap between the SDW and BCS quasi-particle states. While the usual Berry's phase of a SO(3) spinor is described by a Dirac magnetic monopole at the degeneracy point, the non-Abelian holonomy of a SO(5) spinor is described by a Yang monopole at the degeneracy point, and is deeply related to the existence of the second Hopf map from $S^7$ to $S^4$. We conclude this work by extending the bosonic SO(5) nonlinear sigma model to include the fermionic states around the gap nodes as 4 component Dirac fermions coupled to SU(2) gauge fields in 2+1 dimensions.

description: We justify the WKB analysis for generalized nonlinear Schr{ö}dinger equations (NLS), including the hyperbolic NLS and the Davey-Stewartson II system. Since the leading order system in this analysis is not hyperbolic, we work with analytic regularity, with a radius of analyticity decaying with time, in order to obtain better energy estimates. This provides qualitative information regarding equations for which global well-posedness in Sobolev spaces is widely open.

description: A review of various aspects of superstrings in background electromagnetic fields is presented. Topics covered include the Born-Infeld action, spectrum of open strings in background gauge fields, the Schwinger mechanism, finite-temperature formalism and Hagedorn behaviour in external fields, Debye screening, D-brane scattering, thermodynamics of D-branes, and noncommutative field and string theories on D-branes. The electric field instabilities are emphasized throughout and contrasted with the case of magnetic fields. A new derivation of the velocity-dependent potential between moving D-branes is presented, as is a new result for the velocity corrections to the one-loop thermal effective potential.

title: Changes in Payment Timing in Canada’s Large Value Transfer System
Creators: name: Zhang, Nellie
Publisher: name: Bank of Canada
Year: 2015

description: This paper uncovers trends in payment timing in Canada’s Large Value Transfer System (LVTS) from 2003 to 2011. Descriptive analysis shows that LVTS payment activity has not been peaking in the late afternoon since 2008, and the improvement was most significant in 2009. Ordinary least squares regressions are conducted to identify various factors that might have contributed to the changes in the payment value time distribution. The main findings include that a larger proportion of high-value payments results in later payment submission and hence settlement; as an important source of intraday liquidity, a higher CDSX payout value tends to speed up LVTS transactions. Several changes in the system parameters—such as increases in the frequencies of the Jumbo algorithm and Jumbo queue expiry—also quickened the settlement. In addition, the results suggest that the temporary exceptional liquidity initiatives introduced in late 2008 and a large increase in settlement balances were major contributors to the earlier settlement of LVTS payments.
description: L’auteure décrit les tendances qui ressortent de la distribution temporelle des paiements traités par le Système de transfert de paiements de grande valeur (STPGV) au Canada de 2003 à 2011. Une analyse descriptive montre que les opérations de paiement n’ont pas enregistré de pic en fin d’après-midi depuis 2008 et que l’amélioration la plus notable sur ce point s’est produite en 2009. Des régressions par les moindres carrés ordinaires permettent de cerner les facteurs susceptibles d’avoir contribué à modifier la distribution temporelle de la valeur des paiements. Les principaux résultats indiquent qu’une hausse de la proportion des paiements de montant élevé a pour effet de retarder l’envoi et, par conséquent, le règlement des paiements. L’augmentation des paiements en provenance du CDSX tend à accélérer les opérations du STPGV, car ils constituent une importante source de liquidités journalières. Plusieurs changements apportés aux paramètres du système – tels que l’accroissement de la fréquence d’exécution des algorithmes relatifs aux très gros paiements et à l’expiration de l’attente en file – ont aussi favorisé l’accélération du règlement. De plus, les mesures temporaires exceptionnelles d’octroi de liquidités prises à la fin de 2008 et la forte hausse du montant des soldes de règlement ont largement concouru à ce mouvement d’accélération.

description: Whilst the primary bottleneck to a number of computational workflows was not so long ago limited by processing power, the rise of machine learning technologies has resulted in a paradigm shift which places increasing value on issues related to data curation - i.e., data size, quality, bias, format, and coverage. Increasingly, data-related issues are equally as important as the algorithmic methods used to process and learn from the data. Here we introduce an open source GPU-accelerated neural network (NN) framework for learning reactive potential energy surfaces (PESs), and investigate the use of real-time interactive ab initio molecular dynamics in virtual reality (iMD-VR) as a new strategy for rapidly sampling geometries along reaction pathways which can be used to train NNs to learn reactive PESs. Focussing on hydrogen abstraction reactions of CN radical with isopentane, we compare the performance of NNs trained using iMD-VR data versus NNs trained using a more traditional method, namely molecular dynamics (MD) constrained to sample a predefined grid of points along hydrogen abstraction reaction coordinates. Both the NN trained using iMD-VR data and the NN trained using the constrained MD data reproduce important qualitative features of the reactive PESs, such as a low and early barrier to abstraction. Quantitatively, learning is sensitive to the training dataset. Our results show that user-sampled structures obtained with the quantum chemical iMD-VR machinery enable better sampling in the vicinity of the minimum energy path (MEP). As a result, the NN trained on the iMD-VR data does very well predicting energies in the vicinity of the MEP, but less well predicting energies for 'off-path' structures. The NN trained on the constrained MD data does better in predicting energies for 'off-path' structures, given that it included a number of such structures in its training set.
X-ray Emitting Groups in the Infall Region of Abell 2199

description: Using a large redshift survey covering 95 square degrees, we demonstrate that the infall region of Abell 2199 contains Abell 2197, one or two X-ray emitting groups, and up to five additional groups identified in redshift surveys. Our survey shows that the X-ray emitting systems, located at projected radii of $1.^\circ4, 1.^\circ9$, and $5.^\circ1$ (2.2, 3.1, and $8.0 h^{-1}$Mpc), are connected kinematically to A2199. A2197 is itself an optically rich cluster; its weak X-ray emission suggests that it is much less massive than A2199. The absence of a sharp peak in the infall pattern at the position of A2197 supports this hypothesis. The outermost group is well outside the virial region of A2199 and it distorts the infall pattern in redshift space. The two X-ray emitting groups are roughly colinear, suggesting the existence of an extended ($8.0 h^{-1}$Mpc) filament. The identification of these infalling groups provides direct support of hierarchical structure formation; studies of these systems will provide insights into structure evolution. Groups in the infall regions of nearby clusters may offer a unique probe of the physics of the warm/hot ionized medium (WHIM) which is difficult to observe directly with current instruments.

description: The class of nonassociative right hoops, or narhoops for short, is defined as a subclass of right-residuated magmas, and is shown to be a variety. These algebras generalize both right quasigroups and right hoops, and we characterize the subvarieties in which the operation $x\sqcap y=(x / y)y$ is associative and/or commutative. Narhoops with a left unit are proved to have a top element if and only if $\sqcap$ is commutative, and their congruences are determined by the equivalence class of the left unit. We also show that the four identities defining narhoops are independent.
The Kardar-Parisi-Zhang model of a random kinetic growth: effects of a randomly moving medium

description: The effects of a randomly moving environment on a randomly growing interface are studied by the field theoretic renormalization group analysis. The kinetic growth of an interface (kinetic roughening) is described by the Kardar-Parisi-Zhang stochastic differential equation while the velocity field of the moving medium is modelled by the Navier-Stokes equation with an external random force. It is found that the large-scale, long-time (infrared) asymptotic behavior of the system is divided into four nonequilibrium universality classes related to the four types of the renormalization group equations fixed points. In addition to the previously established regimes of asymptotic behavior (ordinary diffusion, ordinary kinetic growth process, and passively advected scalar field), a new nontrivial regime is found. The fixed point coordinates, their regions of stability and the critical dimensions related to the critical exponents (e.g., roughness exponent) are calculated to the first order of the expansion in $ε=2-d$ where $d$ is a space dimension (one-loop approximation) or exactly. The new regime possesses a feature typical to the the Kardar-Parisi-Zhang model: the fixed point corresponding to the regime cannot be reached from a physical starting point. Thus, physical interpretation is elusive.

title: Government and Private E-Money-Like Systems: Federal Reserve Notes and National Bank Notes
Creators: name: Weber, Warren E.
Publisher: name: Bank of Canada
Year: 2015

description: The period from 1914 to 1935 in the United States is unique in that it was the only time that both privately-issued bank notes (national bank notes) and central bank-issued bank notes (Federal Reserve notes) were simultaneously in circulation. This paper describes some lessons relevant to e-money from the U.S. experience during this period. It argues that Federal Reserve notes were not issued to be a superior currency to national bank notes. Rather, they were issued to enable the Federal Reserve System to act as a lender of last resort in times of financial stress. It also argues that the reason to eventually eliminate national bank notes was that they were potentially a source of bank reserves. As such, they could have threatened the Federal Reserve System’s control of the reserves of the banking system and thereby the Fed’s control of monetary policy.
description: Aux États-Unis, la période allant de 1914 à 1935 présente un caractère unique car c’est la seule époque où des billets émis par des entités privées (les banques nationales) et la banque centrale (la Réserve fédérale) circulaient en parallèle. L’auteur décrit quelques enseignements applicables aux monnaies électroniques, tirés de cette époque aux États-Unis. Il soutient que l’émission de billets par la Réserve fédérale n’avait pas pour objectif de créer une monnaie supérieure aux billets des banques nationales, mais de permettre à la Réserve fédérale d’offrir des prêts de dernier ressort en cas de tensions financières. Il affirme également que c’est parce qu’ils pouvaient représenter une source de réserves bancaires que les billets des banques nationales ont finalement été retirés de la circulation. Ainsi, ils auraient pu menacer le contrôle exercé par la Réserve fédérale sur les réserves du système bancaire et, par conséquent, sur la politique monétaire.

description: Negative friction coefficients, where friction is reduced upon increasing normal load, are predicted for superlubric graphite-hexagonal boron nitride heterojunctions. The origin of this counterintuitive behavior lies in the load-induced suppression of the moiré superstructure out-of-plane distortions leading to a less dissipative interfacial dynamics. Thermally induced enhancement of the out-of-plane fluctuations leads to an unusual increase of friction with temperature. The highlighted frictional mechanism is of a general nature and is expected to appear in many layered material heterojunctions.

description: The response to a parallel magnetic field of the very dilute insulating two-dimensional system of electrons in silicon MOSFET's is dramatic and similar to that found on the conducting side of the metal-insulator transition: there is a large initial increase in resistivity with increasing field, followed by saturation to a value that is approximately constant above a characteristic magnetic field of about one Tesla. This is unexpected behavior in an insulator that exhibits Efros-Shklovskii variable-range hopping in zero field, and appears to be a general feature of very dilute electron systems.
