description: The reaction systems, 64Zn + 58Ni, 64Zn + 92Mo, 64Zn + 197Au, at 26A, 35A and 47A MeV, have been studied both in experiments with a 4$π$ detector array, NIMROD, and with Antisymmetrized Molecular Dynamics model calculations employing effective interactions corresponding to soft and stiff equations of state (EOS). Direct experimental observables, such as multiplicity distributions, charge distributions, energy spectra and velocity spectra, have been compared in detail with those of the calculations and a reasonable agreement is obtained. The velocity distributions of $α$ particles and fragments with Z >= 3 show distinct differences in calculations with the soft EOS and the stiff EOS. The velocity distributions of $α$ particle and Intermediate Mass Fragments (IMF's) are best described by the stiff EOS. Neither of the above direct observables nor the strength of the elliptic flow are sensitive to changes in the in-medium nucleon-nucleon (NN) cross sections. A detailed analysis of the central collision events calculated with the stiff EOS revealed that multifragmentation with cold fragment emission is a common feature predicted for all reactions studied here. A possible multifragmentation scenario is presented; after the preequilibrium emission ceases in the composite system, cold light fragments are formed in a hotter gas of nucleons and stay cold until the composite system underdoes multifragmentation. For reaction with 197Au at 47A MeV a significant radial expansion takes place. For reactions with 58Ni and 92Mo at 47A MeV semi-transparency becomes prominent. The differing reaction dynamics drastically change the kinematic characteristics of emitted fragments. This scenario gives consistent explanations for many existing experimental results in the Fermi energy domain.

Taiwan • New Taipei, Mt. Pataoerh, 600–700 m, 29 Apr 2016, Hsu 8437 (holotype TAIF [497137!]; isotype TAIF [497138!]).
Distribution and ecology.
This species, recently described from Taiwan, was initially reported from southern China and Taiwan (Chao et al. 2021). In Vietnam, P. pseudowulaiensis was discovered in relatively dry evergreen broadleaf forests at lowland areas of Cuc Phuong National Park.
Specimens examined.
Vietnam • Ninh Binh Province: Cuc Phuong National Park, Muong Khu trail, Y.-S. Chao 3509, 3515, 3517, 3531 (TAIF!, VNMN!).
Note.
This species belongs to the Pteris fauriei Hieron. complex, a taxonomically challenging group due to its reticulate evolution involving hybridization, polyploidization, and apomixis (Chao et al. 2022). In Vietnam, five species from this complex have been recorded, namely P. arisanensis Tagawa (Chao et al. 2022), P. kawabatae Sa. Kurata (Chao et al. 2021), P. latipinna Y. S. Chao & W. L. Chiou (Chen et al. 2020 b), P. oshimensis Hieron. (Liao et al. 2013), and P. pseudowulaiensis. Morphologically, P. pseudowulaiensis closely resembles P. oshimensis but differs by having broader pinnae, measuring 2–3.5 cm compared to less than 2 cm in P. oshimensis. According to Chao et al. (2022), P. pseudowulaiensis is an apogamous diploid originating from hybridization of P. wulaiensis C. M. Kuo (a species reported from Japan and Taiwan) and another unknown species.

description: Due to the fourth industrial revolution, industrial applications make use of the progress in communication and embedded devices. This allows industrial users to increase efficiency and manageability while reducing cost and effort. Furthermore, the fourth industrial revolution, creating the so-called Industry 4.0, opens a variety of novel use and business cases in the industrial environment. However, this progress comes at the cost of an enlarged attack surface of industrial companies. Operational networks that have previously been phyiscally separated from public networks are now connected in order to make use of new communication capabilites. This motivates the need for industrial intrusion detection solutions that are compatible to the long-term operation machines in industry as well as the heterogeneous and fast-changing networks. In this work, process data is analysed. The data is created and monitored on real-world hardware. After a set up phase, attacks are introduced into the systems that influence the process behaviour. A time series-based anomaly detection approach, the Matrix Profiles, are adapted to the specific needs and applied to the intrusion detection. The results indicate an applicability of these methods to detect attacks in the process behaviour. Furthermore, they are easily integrated into existing process environments. Additionally, one-class classifiers One-Class Support Vector Machines and Isolation Forest are applied to the data without a notion of timing. While Matrix Profiles perform well in terms of creating and visualising results, the one-class classifiers perform poorly.

description: We analyze deep near-IR adaptive optics imaging as well as new proper motion data of the nuclear star cluster of the Milky Way. The surface density distribution of faint stars peaks within 0.2" of the black hole candidate SgrA*. The radial density distribution of this stellar 'cusp' follows a power law of exponent 1.3-1.4. The K-band luminosity function of the overall nuclear stellar cluster (within 9" of SgrA*) resembles that of the large scale, Galactic bulge, but shows an excess of stars at K<14. We find that most of the massive early type stars at distances 1-10" from SgrA* are located in two rotating and geometrically thin disks. These disks are inclined at large angles and counter-rotate with respect to each other. Their stellar content is essentially the same, indicating that they formed at the same time. The star closest to SgrA* in 2002, S2, exhibits a 3.8 micron excess. We propose that the mid-IR emission either comes from the accretion flow around the black hole itself, or from dust in the accretion flow that is heated by the ultra-violet emission of S2.

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

title: Productivity, the Terms of Trade, and the Real Exchange Rate: The Balassa-Samuelson Hypothesis Revisited
Creators: name: Choudhri, Ehsan U.
name: Schembri, Lawrence L.
Publisher: name: Bank of Canada
Year: 2009

description: The paper examines how the Balassa-Samuelson hypothesis is affected by a modern variation of the standard model that allows product differentiation (within the traded and nontraded goods sectors) with the number of firms determined exogenously or endogenously. The hypothesis is found to be fragile in the modified framework. Small variations in the elasticity of substitution between home and foreign traded goods (within the range of estimates suggested in the literature), for example, can make the effect of a traded-goods productivity improvement on the real exchange rate negative or positive, as well as small or large. This result provides a potential explanation of the mixed empirical results that have been obtained on the relationship between productivity and the real exchange rate.
description: Les auteurs évaluent l'incidence qu'a sur l'hypothèse de Balassa-Samuelson une variante moderne du modèle de référence qui autorise une différenciation des produits (au sein des secteurs des biens échangeables et non échangeables) et une détermination exogène ou endogène du nombre d'entreprises. L'hypothèse, dans ce cadre modifié, apparaît fragile. De menues variations de l'élasticité de substitution entre les biens échangeables fabriqués au pays et ceux fabriqués à l'étranger (dans les limites des estimations proposées dans la littérature), par exemple, peuvent rendre négatif ou positif l'effet d'une amélioration de la productivité dans le secteur des biens échangeables sur le taux de change réel et atténuer ou amplifier cet effet. Ce résultat explique peut-être la diversité des observations empiriques recueillies à propos de la relation entre la productivité et le taux de change réel.

description: The Crab Nebula was discovered as the first very-high-energy gamma-ray source by the Whipple Observatory in 1989. Thirty years after its discovery it is still the reference source and the standard candle for Imaging Atmospheric Cherenkov Telescopes (IACTs). Its spectrum has been measured from the cm radio band to energies up to tens of TeV. Some studies reported a possible but still debated cut-off in its spectrum at few tens of TeV. The MAGIC collaboration is currently investigating the spectrum of the Crab Nebula by using the Very Large Zenith Angle observation technique. The latter provides a significantly increased collection area for energies above 10 TeV. The details of these MAGIC observations will be presented.

description: The importance of many-body dispersion effects in layered materials subjected to high external loads is evaluated. State-of-the-art many-body dispersion density functional theory calculations performed for graphite, hexagonal boron nitride, and their hetero-structures were used to fit the parameters of a classical registry-dependent interlayer potential. Using the latter, we performed extensive equilibrium molecular dynamics simulations and studied the mechanical response of homogeneous and heterogeneous bulk models under hydrostatic pressures up to 30 GPa. Comparison with experimental data demonstrates that the reliability of the many-body dispersion model extends deep into the sub-equilibrium regime. Friction simulations demonstrate the importance of many-body dispersion effects for the accurate description of the tribological properties of layered materials interfaces under high pressure.

title: Short Changed? The Market's Reaction to the Short Sale Ban of 2008
Creators: name: Gagnon, Louis

Publisher: name: Bank of Canada
Year: 2009

description: Do short sales restrictions have an impact on security prices? We address this question in the context of a natural experiment surrounding the short sale ban of 2008 using a comprehensive sample of Canadian stocks cross-listed in the U.S. Among financial stocks, which were singled out by the ban in both countries, we observe a significant increase (74 bps) in the difference between the U.S. share price and the Canadian share price. We also observe an impressive and surprising migration of the trading volume from the U.S. to Canada among financial stocks during the ban. Both price and volume effects are reversed after the ban and neither effect manifests itself among the nonfinancial stocks. Our findings support the view that prices reflect a more optimistic valuation when pessimistic investors are kept out of the market by binding short-sales restrictions (Miller (1977)). Our findings also imply that pessimistic investors were more preponderant in the U.S. than in Canada, which is corroborated by the fact that the short interest ratio for our sample stocks was much larger in the U.S. than in Canada prior to the ban.
description: L'imposition de restrictions sur les ventes de titres à découvert a-t-elle une incidence sur les cours? Les auteurs analysent la question dans le contexte d'une expérience naturelle entourant la courte période durant laquelle le Canada et les États-Unis ont prohibé ces opérations sur les titres financiers en 2008. Ils utilisent à cette fin un vaste échantillon d'actions de sociétés canadiennes inscrites à la cote d'une bourse américaine. Pour la période d'interdiction, ils observent un élargissement considérable (74 points de base) de l'écart des cours des titres financiers entre les deux pays ainsi qu'un déplacement spectaculaire et étonnant du volume des opérations sur ces titres vers le Canada. Les effets de prix et de volume, dont aucun ne se manifeste dans le cas des titres non financiers, s'inversent après la levée de l'interdiction. De tels résultats tendent à confirmer que les cours reflètent un optimisme accru lorsque les investisseurs pessimistes sont tenus en dehors du marché par l'action contraignante d'une restriction des ventes à découvert (Miller, 1977). Ils impliquent également que ces investisseurs prédominaient davantage aux États-Unis, ce que corrobore le fait que, avant le début de la période d'interdiction, la proportion des titres vendus à découvert dans l'échantillon retenu était beaucoup plus élevée dans ce pays qu'au Canada.

description: We propose a straightforward extension of our previously proposed log-periodic power law model of the ``anti-bubble'' regime of the USA market since the summer of 2000, in terms of the renormalization group framework to model critical points. Using a previous work by Gluzman and Sornette (2002) on the classification of the class of Weierstrass-like functions, we show that the five crashes that occurred since August 2000 can be accurately modelled by this approach, in a fully consistent way with no additional parameters. Our theory suggests an overall consistent organization of the investors forming a collective network which interact to form the pessimistic bearish ``anti-bubble'' regime with intermittent acceleration of the positive feedbacks of pessimistic sentiment leading to these crashes. We develop retrospective predictions, that confirm the existence of significant arbitrage opportunities for a trader using our model. Finally, we offer a prediction for the unknown future of the US S&P500 index extending over 2003 and 2004, that refines the previous prediction of Sornette and Zhou (2002).

title: Resurrecting the Role of Real Money Balance Effects
Creators: name: Dorich, Jose
Publisher: name: Bank of Canada
Year: 2009

description: I present a structural econometric analysis supporting the hypothesis that money is still relevant for shaping inflation and output dynamics in the United States. In particular, I find that real money balance effects are quantitatively important, although smaller than they used to be in the early postwar period. Moreover, I show three additional implications of the econometric estimates for monetary policy analysis. First, by including real money balance effects into the standard sticky price model, two stylized facts can be explained: the modestly procyclical real wage response to a monetary policy shock and the supply side effects of monetary policy. Second, the existence of real money balance effects causes higher volatility of output and lower volatility of interest rates under the optimal monetary policy. Third, the reduction in the size of real money balance effects can account for a significant decline in macroeconomic volatility.
description: L'auteur présente une analyse économétrique structurelle qui valide l'hypothèse selon laquelle la monnaie joue toujours un rôle pertinent dans l'évolution de l'inflation et de la production aux États-Unis. Il conclut en particulier à l'importance quantitative des effets d'encaisses réelles, bien que ceux-ci soient désormais moindres qu'au sortir de la guerre. Sur le plan de l'analyse de la politique monétaire, trois autres implications se dégagent des estimations économétriques obtenues. D'abord, l'intégration d'effets d'encaisses réelles dans un modèle type à prix rigides permet d'éclaircir deux faits stylisés : la réaction procyclique modérée des salaires à un choc de politique monétaire et les effets de la politique monétaire sur l'offre. Ensuite, l'existence d'effets d'encaisses réelles accentue la volatilité de la production, mais réduit celle des taux d'intérêt en contexte de politique monétaire optimale. Enfin, la diminution de l'ampleur des effets d'encaisses réelles est un facteur explicatif potentiel de la forte baisse de la volatilité à l'échelle macroéconomique.

title: Credit Constraints and Consumer Spending
Creators: name: Beaton, Kimberly
Publisher: name: Bank of Canada
Year: 2009

description: This paper examines the relationship between aggregate consumer spending and credit availability in the United States. The author finds that consumer spending falls (rises) in response to a reduction (increase) in credit availability. Moreover, she provides a formal assessment of the possibility that credit availability is particularly important for consumer spending when it undergoes large changes. In this respect, she estimates a consumption function in which only large expansions and contractions in credit affect spending. She concludes that large changes in credit availability are particularly important for consumers' spending decisions. As should be expected, these periods tend to be associated with periods of high economic uncertainty. These results show that credit availability should be taken into account when modeling and forecasting consumer spending.
description: L'étude porte sur la relation entre les dépenses de consommation globales et la disponibilité du crédit aux États-Unis. L'auteure constate que les dépenses de consommation diminuent (augmentent) lorsque la disponibilité du crédit décroît (s'accroît). En outre, elle analyse de façon formelle la possibilité que la disponibilité du crédit, lorsque celle-ci varie fortement, soit particulièrement importante pour les dépenses de consommation. À cet égard, elle estime une fonction de consommation dans laquelle seuls les mouvements prononcés d'expansion ou de contraction du crédit agissent sur les dépenses. Elle conclut que les variations marquées de la disponibilité du crédit ont une importance particulière pour les décisions de dépense des consommateurs. Comme il était à prévoir, de telles variations sont généralement associées aux périodes de grande incertitude économique. Ces résultats montrent que la disponibilité du crédit devrait être prise en compte dans la modélisation des dépenses de consommation et l'établissement des prévisions connexes.

description: XMM-Newton recently discovered O VII line emission from ~2 million K gas near the outer parts of several clusters of galaxies. This emission is attributed to the Warm-Hot Intergalactic Medium. The original sample of clusters studied for this purpose has been extended and two more clusters with a soft X-ray excess have been found. We discuss the physical properties of the warm gas, in particular the density, spatial extent, abundances and temperature.

Pure electromagnetic-gravitational interaction in Hořava-Lifshitz theory at the kinetic conformal point

Subjects: subject: High Energy Physics - Theory (hep-th)

description: We introduce the electromagnetic-gravitational coupling in the Hořava-Lifshitz framework, in $3+1$ dimensions, by considering the Hořava-Lifshitz gravity theory in $4+1$ dimensions at the kinetic conformal point and then performing a Kaluza-Klein reduction to $3+1$ dimensions. The action of the theory is second order in time derivatives and the potential contains only higher order spacelike derivatives up to $z=4$, $z$ being the critical exponent. These terms include also higher order derivative terms of the electromagnetic field. The propagating degrees of freedom of the theory are exactly the same as in the Einstein-Maxwell theory. We obtain the Hamiltonian, the field equations and show consistency of the constraint system. The kinetic conformal point is protected from quantum corrections by a second class constraint. At low energies the theory depends on two coupling constants, $β$ and $α$. We show that the anisotropic field equations for the gauge vector is a deviation of the covariant Maxwell equations by a term depending on $β-1$. Consequently, for $β=1$, Maxwell equations arise from the anisotropic theory at low energies. We also prove that the anisotropic electromagnetic-gravitational theory at the IR point $β=1$, $α=0$, is exactly the Einstein-Maxwell theory in a gravitational gauge used in the ADM formulation of General Relativity.

description: A parent insulator of the Bi-based high-$T_c$ superconductor Bi$_2$Sr$_{2-x}$La$_x$CaCu$_2$O$_{8+δ}$ was successfully grown by a traveling solvent floating zone method. The in-plane resistivity $ρ_{ab}$ shows metallic behavior ($dρ_{ab}/dT >$ 0) near room temperature, although the magnitude of the resistivity is far above the Mott limit for metallic conduction. The Hall mobility of the parent insulator does not so much differ from that of an optimally doped sample. These results suggest that the system is not a simple insulator with a well-defined gap, and the hole in the parent insulator is essentially itinerant, as soon as it is doped.

description: The five-minute oscillations in the Sun have provided a wealth of information about the solar interior. After many attempts, positive detections of similar oscillations in solar-type stars have now been made. This review discusses the properties of solar-like oscillations, the methods used to observe them and the results on individual stars. We conclude that the study of solar-like oscillations from the ground and space has an exciting future.

description: Using Bayesian methods, we estimate a small open economy model in which consumers face limits to credit determined by the value of their housing stock. The purpose of this paper is to quantify the role of collateralized household debt in the Canadian business cycle. Our findings show that the presence of borrowing constraints improves the performance of the model in terms of overall goodness of fit. In particular, the presence of housing collateral generates a positive correlation between consumption and house prices. Finally we find that housing collateral induced spillovers account for a large share of consumption growth during the housing market boom-bust cycle of the late 1980s.
description: À l'aide de techniques bayésiennes, les auteurs estiment le modèle d'une petite économie ouverte au sein de laquelle le pouvoir d'emprunt des consommateurs est limité par la valeur de leur patrimoine immobilier. L'étude vise à quantifier le rôle joué par les emprunts des ménages adossés à des actifs réels dans le cycle économique au Canada. D'après les résultats obtenus, l'introduction de contraintes de crédit améliore l'adéquation générale du modèle. En particulier, la présence de garanties immobilières permet d'établir une corrélation positive entre la consommation et le prix des maisons. Les auteurs constatent en dernier lieu que les effets induits par ce type de garantie expliquent dans une large mesure la croissance de la consommation pendant le cycle d'envolée et d'effondrement des prix du logement à la fin des années 1980.

description: We present first results of our planet search program using the 9.2 meter Hobby-Eberly Telescope (HET) at McDonald Observatory to detect planets around M-type dwarf stars via high-precision radial velocity (RV) measurements. Although more than 100 extrasolar planets have been found around solar-type stars of spectral type F to K, there is only a single M-dwarf (GJ 876, Delfosse et al. 1998; Marcy et al. 1998; Marcy et al. 2001) known to harbor a planetary system. With the current incompleteness of Doppler surveys with respect to M-dwarfs, it is not yet possible to decide whether this is due to a fundamental difference in the formation history and overall frequency of planetary systems in the low-mass regime of the Hertzsprung-Russell diagram, or simply an observational bias. Our HET M-dwarf survey plans to survey 100 M-dwarfs in the next 3 to 4 years with the primary goal to answer this question. Here we present the results from the first year of the survey which show that our routine RV-precision for M-dwarfs is 6 m/s. We found that GJ 864 and GJ 913 are binary systems with yet undetermined periods, while 5 out of 39 M-dwarfs reveal a high RV-scatter and represent candidates for having short-periodic planetary companions. For one of them, GJ 436 (rms = 20.6 m/s), we have already obtained follow-up observations but no periodic signal is present in the RV-data.

description: The study used a case study approach and a survey questionnaire to collect data on farmers markets in the Alabama Black Belt. Specific objectives were to describe the current state of development of farmers markets, categorize the farmers markets, and make comparisons between and assessments of the various markets. The data were summarized and tabulated using descriptive statistics. A typology was developed with three categories and associated intervention policy or program attributes identified for farmers markets. It was found that there were three developed markets, all in urban areas; four developing markets, which had one market in the urban, two in the suburban, and one in the rural areas; and seven underdeveloped farmers markets, most of which were in rural areas. Consequently, it was recommended that for underdeveloped and developing farmers markets to move into the developed category, assistance must be provided with a mix of interventions that comprise facilities, proper organization, and efforts to strengthen the customer base. Such technical assistance will contribute to increased sales and economic activity in the communities.

description: We present a theoretical study of the infrared magneto-optical properties of ferromagnetic (III,Mn)V semiconductors. Our analysis combines the kinetic exchange model for (III,Mn)V ferromagnetism with Kubo linear response theory and Born approximation estimates for the effect of disorder on the valence band quasiparticles. We predict a prominent feature in the ac-Hall conductivity at a frequency that varies over the range from 200 to 400 meV, depending on Mn and carrier densities, and is associated with transitions between heavy-hole and light-hole bands. In its zero frequency limit, our Hall conductivity reduces to the $\vec k$-space Berry's phase value predicted by a recent theory of the anomalous Hall effect that is able to account quantitatively for experiment. We compute theoretical estimates for magnetic circular dichroism, Faraday rotation, and Kerr effect parameters as a function of Mn concentration and free carrier density. The mid-infrared response feature is present in each of these magneto-optical effects.

GRB 030226 in a Density-Jump Medium

Publisher: name: arXiv

Subjects: subject: Astrophysics (astro-ph)

description: We present an explanation for the unusual temporal feature of the GRB 030226 afterglow. The R-band afterglow of this burst faded as ~ t^{-1.2} in ~ 0.2 days after the burst, rebrightened during the period of ~ 0.2 - 0.5 days, and then declined with ~ t^{-2.0}. To fit such a light curve, we consider an ultrarelativistic jetted blast wave expanding in a density-jump medium. The interaction of the blast wave with a large density jump produces relativistic reverse and forward shocks. In this model, the observed rebrightening is due to emissions from these newly forming shocks, and the late-time afterglow is caused by sideways expansion of the jet. Our fitting implies that the progenitor star of GRB 030226 could have produced a stellar wind with a large density jump prior to the GRB onset.

title: Risk Premium Shocks and the Zero Bound on Nominal Interest Rates
Creators: name: Amano, Robert
name: Shukayev, Malik
Publisher: name: Bank of Canada
Year: 2009

description: There appears to be a disconnect between the importance of the zero bound on nominal interest rates in the real-world and predictions from quantitative DSGE models. Recent economic events have reinforced the relevance of the zero bound for monetary policy whereas quantitative models suggest that the zero bound does not constrain (optimal) monetary policy. This paper attempts to shed some light on this disconnect by studying a broader range of shocks within a standard DSGE model. Without denying the possibility of other factors, we find that risk premium shocks are key to building quantitative models where the zero bound is relevant for monetary policy design. The risk premium mechanism operates by increasing the spread between the rates of return on private capital and risk-free government bonds. Other common shocks, such as aggregate productivity, investment-specific productivity, government spending and money demand shocks, are unable to push nominal bond rates close to zero as the same risk premium spread mechanism is not at play.
description: Il semble que la borne limitant à zéro les taux d'intérêt nominaux revête une importance réelle, contrairement à ce que prévoient les modèles quantitatifs d'équilibre général dynamiques et stochastiques (EGDS). Alors que les événements récents sur la scène économique sont venus souligner la pertinence de cette borne pour la politique monétaire, les modèles quantitatifs indiquent plutôt que la borne du zéro ne constitue pas une contrainte pour la conduite d'une politique monétaire optimale. Les auteurs tentent d'élucider cette contradiction en examinant une gamme élargie de chocs à l'intérieur d'un modèle EGDS. Sans nier l'action possible d'autres facteurs, ils font ressortir le rôle clé des chocs touchant la prime de risque dans l'élaboration de modèles quantitatifs où la borne du zéro représente une contrainte pour la conception de la politique monétaire. Le mécanisme faisant intervenir la prime de risque opère en creusant l'écart entre le taux de rendement des capitaux privés et le taux des obligations d'État sans risque. Les chocs communément observés au niveau de la productivité globale, de la productivité propre à l'investissement, des dépenses publiques et de la demande de monnaie ne permettent pas d'abaisser les taux obligataires nominaux près de zéro si la prime de risque n'augmente pas elle-même.

description: The magnetic properties in two-dimensional van der Waals materials depend sensitively on structure. CrI3, as an example, has been recently demonstrated to exhibit distinct magnetic properties depending on the layer thickness and stacking order. Bulk CrI3 is ferromagnetic (FM) with a Curie temperature of 61 K and a rhombohedral layer stacking, while few-layer CrI3 has a layered antiferromagnetic (AFM) phase with a lower ordering temperature of 45 K and a monoclinic stacking. In this work, we use cryogenic magnetic force microscopy to investigate CrI3 flakes in the intermediate thickness range (25 - 200 nm) and find that the two types of magnetic orders hence the stacking orders can coexist in the same flake, with a layer of ~13 nm at each surface being in the layered AFM phase similar to few-layer CrI3 and the rest in the bulk FM phase. The switching of the bulk moment proceeds through a remnant state with nearly compensated magnetic moment along the c-axis, indicating formation of c-axis domains allowed by a weak interlayer coupling strength in the rhombohedral phase. Our results provide a comprehensive picture on the magnetism in CrI3 and point to the possibility of engineering magnetic heterostructures within the same material.

 Type species. Trestonia forticornis Buquet, 1859, subsequent designation by Thomson 1864: 103.
 The genus Trestonia currently contains 21 described species. Nearns et al. (2011) provided color photographs for 17 type specimens of this genus. We believe the genus is in need of a taxonomic revision (Nearns and Tavakilian in preparation).
