title: Prévision et analyse de la production manufacturière au Canada : comparaison de modèles linéaires et non linéaires
Creators: name: Demers, Frédérick
Publisher: name: Bank of Canada
Year: 2004

description: In this paper, the author describes reduced-form linear and non-linear econometric models developed to forecast and analyze quarterly data on output growth in the Canadian manufacturing sector from 1981 to 2003. Empirical evidence reported in the paper suggests that economic activity in the United States and the real exchange rate are the main factors that influence output in the manufacturing sector in Canada.

Although the real exchange rate has a significant impact, the response of output to exchange rate shocks is highly asymmetric. In addition, non-linear Markov switching models appear to better explain the growth of output and provide more accurate out-of-sample forecasts. Because of the asymmetry, empirical evidence shows the need to take into account conditional rather than unconditional elasticities to the state of production in the manufacturing sector, especially when analyzing the response of output to real exchange rate shocks.
description: Cette étude présente des modèles économétriques linéaires et non linéaires à forme réduite élaborés afin de prévoir et d'analyser la croissance trimestrielle de la production manufacturière au Canada sur la période 1981-2003. Les résultats empiriques présentés dans cette étude indiquent que l'activité économique américaine et le taux de change réel sont les principaux déterminants de la production manufacturière canadienne.

Quoique le taux de change réel ait une incidence significative, la réaction de la production aux chocs de taux de change présente une asymétrie importante. De plus, les modèles non linéaires à changements de régime markovien semblent mieux caractériser la croissance de la production et offrent aussi de meilleures prévisions hors échantillon. En raison de la forte asymétrie mentionnée, les résultats illustrent aussi la nécessité de prendre en compte des élasticités conditionnelles, plutôt qu'inconditionnelles, à l'état dans lequel se trouve la production manufacturière, particulièrement dans le cas de la réaction de la production aux chocs de taux de change réel.
title: Characterization of the Dynamic Effects of Fiscal Shocks in a Small Open Economy
Creators: name: Rebei, Nooman
Publisher: name: Bank of Canada
Year: 2004

description: The author studies the macroeconomic consequences of discretionary changes in the fiscal policy instruments for Canada. He adopts a semi-structural vector autoregression framework. Restrictions are based on institutional interactions between some policy and non-policy instruments that mimic a government's decision process. The author characterizes the actual economy's response to fiscal shocks, and proposes a theoretical model for a small open economy with nominal and real rigidities to test for the endogenous transmission mechanisms following shocks to government spending. He pursues a limited-information econometric strategy by comparing the theoretical impluse-response functions with the empirical ones, capturing the effects of a disturbance in government spending. Generally, the results of the model are very close to the observed reactions, especially for consumption, investment, exports, imports, and inflation; however, the model fails to predict the real exchange rate reaction.
description: L'auteur se penche sur les conséquences macroéconomiques de modifications discrétionnaires apportées aux instruments de la politique budgétaire dans le contexte canadien. Son analyse repose sur un cadre semi-structurel d'autorégression vectorielle. Dans le but de simuler le processus décisionnel des autorités, l'auteur incorpore certaines restrictions, fondées sur le jeu des interactions institutionnelles d'une série d'instruments budgétaires et non budgétaires. Il décrit la réaction réelle de l'économie à des chocs budgétaires et propose un modèle théorique afin de tester les mécanismes de transmission endogènes des chocs que génère une variation imprévue des dépenses publiques dans une petite économie ouverte où existent des rigidités nominales et réelles. Pour représenter les effets de telles variations, il compare les profils de réaction théoriques aux profils empiriques dégagés, dans le cadre d'une méthode d'estimation à information limitée. En général, le modèle reproduit très bien les réactions observées, surtout celles de la consommation, de l'investissement, des exportations, des importations et de l'inflation, mais il ne réussit pas à prévoir celle du taux de change réel.

AbstractCertolizumab pegol (Cimzia®) is a PEGylated, Fab'-only, recombinant humanized antibody against TNF-α. Subcutaneous certolizumab pegol is indicated for the treatment of various immune-mediated inflammatory diseases (IMIDs), including moderate to severe plaque psoriasis. In pivotal phase III trials in adults with moderate to severe plaque psoriasis, significantly more patients receiving certolizumab pegol 200 mg or 400 mg once every 2 weeks than placebo recipients achieved a ≥ 75% reduction in PASI score (PASI75 responder) and a PGA score of clear/mostly clear with a ≥ 2 point improvement from baseline (PGA0/1 responder) at week 12 (CIMPACT) or 16 (CIMPASI-1 and -2). In CIMPACT, certolizumab pegol 400 mg once every 2 weeks was superior to etanercept (highest recommended dosage) at 12 weeks, with certolizumab pegol 200 mg once every 2 weeks demonstrating non-inferiority, but not superiority, to etanercept. The clinical benefits of certolizumab pegol were maintained during the maintenance phase (to week 48) and the open-label extension phase of these trials. Certolizumab pegol is unique among the biologics, with the absence of an Fc fragment conferring pharmacokinetic advantages; most notably, its minimal transfer across the placenta or into breast milk. Certolizumab pegol was generally well tolerated and no new safety signals were identified in these phase III trials, which complements its established safety profile in other IMIDs. Certolizumab pegol is a useful option for the treatment of moderate to severe plaque psoriasis and provides an important treatment option for pregnant or breastfeeding patients, for whom there are limited options available.© Springer Nature Switzerland AG 2020

Year: 2004

description: The authors model trading by foreign and domestic investors in developed-country equity markets. The key assumptions are that (i) both the foreign and domestic investor populations contain investors of different sophistication, and (ii) investor sophistication matters for performance in both public equity and private off-market investments. A quantitative model with these assumptions delivers a unified explanation for three stylized facts about U.S. investors' international equity trades that have been documented in the literature: (i) trading by U.S. investors occurs in bursts of simultaneous buying and selling, (ii) Americans build and unwind foreign equity positions gradually, and (iii) U.S. investors increase their market share in a country when stock prices in that country have recently been rising.
description: Les auteurs modélisent l'activité boursière des investisseurs étrangers et nationaux dans les pays développés. Leur étude repose sur deux grandes hypothèses : i) le niveau de connaissance des marchés financiers varie parmi les investisseurs, tant étrangers que nationaux; ii) la familiarité des investisseurs avec le fonctionnement des marchés influe aussi bien sur le rendement des placements à la bourse que sur celui des placements privés hors marché. Le modèle quantitatif proposé permet d'expliquer de façon cohérente trois faits stylisés, mis en évidence dans la littérature, concernant l'activité boursière internationale des investisseurs américains. Premièrement, les transactions de ce groupe d'investisseurs prennent la forme de vagues simultanées d'achats et de ventes. Deuxièmement, ces investisseurs accroissent graduellement leurs participations à l'étranger et s'en défont tout aussi progressivement. Troisièmement, ils se portent acquéreurs de volumes accrus d'actions dans un pays donné quand les prix des valeurs mobilières y augmentent depuis peu.
title: Real Return Bonds, Inflation Expectations, and the Break-Even Inflation Rate

Year: 2004

description: According to the Fisher hypothesis, the gap between Canadian nominal and Real Return Bond yields (or break-even inflation rate) should be a good measure of inflation expectations. The authors find that this measure was higher, on average, and more variable than survey measures of inflation expectations between 1992 and 2003. They examine whether risk premiums and distortions embedded in this interest rate gap can account for these facts. Their results indicate that distortions were likely an important reason for the high level and variation of this measure over much of the 1990s. There is little evidence that the distortions examined were as important between 2000 and 2003, but the high level of the break-even inflation rate in 2004 may be evidence of their return. Given the potential distortions, and the difficulty in identifying them, the authors conclude that it is premature to consider this measure a reliable gauge of monetary policy credibility. In addition, it is not as useful as competing tools for short- and medium-term inflation forecasting.
description: Selon l'hypothèse de Fisher, l'écart de rendement entre les obligations canadiennes à rendement nominal et à rendement réel (ou taux d'inflation neutre) devrait être un bon indicateur des attentes d'inflation. Les auteurs constatent qu'entre 1992 et 2003, cet écart a été supérieur, en moyenne, aux mesures de l'inflation attendue établies par enquête, et plus variable également. Ils cherchent à savoir si les primes de risque et les distorsions comprises dans l'écart de rendement y sont pour quelque chose. D'après leurs résultats, les distorsions expliquent probablement en bonne partie le niveau élevé et les variations de l'écart de rendement durant la majeure partie des années 1990. Rien ne porte à croire qu'elles aient été aussi importantes entre 2000 et 2003, mais le niveau élevé du taux d'inflation neutre en 2004 pourrait être le signe de leur résurgence. Étant donné les distorsions possibles et la difficulté de les prendre en compte, les auteurs concluent qu'il est prématuré de considérer cette mesure comme un baromètre fiable de la crédibilité de la politique monétaire. En outre, le taux d'inflation neutre n'est pas aussi utile que les autres outils existants pour la prévision de l'inflation à court et à moyen terme.

description: The ground states of the $S=\frac12$ Heisenberg chain with the nearest-neighbor and the next-nearest-neighbor antiferromagnetic couplings are numerically investigated in a staggered magnetic field. While the staggered magnetic field may induce the Néel-type excitation gap, and it is characterized by the Gaussian fixed point in the spin-fluid region, the crossover to the behavior controlled by the Ising fixed point is expected to be observed for the spontaneously dimerized state at finite field. Treating a low-lying excitation gap by the phenomenological renormalization-group method, we numerically determine the massless flow connecting the Gaussian and Ising fixed points. Further, to check the criticalities, we perform the finite-size-scaling analysis of the excitation gap.

The Maximum Common Subgraph Problem: A Portfolio Approach

description: The Maximum Common Subgraph is a computationally challenging problem with countless practical applications. Even if it has been long proven NP-hard, its importance still motivates searching for exact solutions. This work starts by discussing the possibility to extend an existing, very effective branch-and-bound procedure on parallel multi-core and many-core architectures. We analyze a parallel multi-core implementation that exploits a divide-and-conquer approach based on a thread-pool, which does not deteriorate the original algorithmic efficiency and it is not memory bound. We extend the algorithm to parallel many-core GPU architectures adopting the CUDA programming framework, and we show how to handle the heavily workload-unbalance and the massive data dependency. Then, we suggest new heuristics that reorder the adjacency matrix, deal with "dead-ends" and randomize the search with automatic restarts, achieving significant improvements on specific cases. Finally, we propose a portfolio approach, which integrates all the different local search algorithms as component tools. Such portfolio, rather than choosing the best tool for a given instance up-front, takes the decision on-line. The proposed approach drastically limits memory bandwidth constraints and avoids other typical portfolio fragilities as CPU and GPU versions often show a complementary efficiency and run on separated platforms. Experimental results support the claims and motivate further research to better exploit GPUs in embedded task-intensive, and multi-engine parallel applications.

description: We propose the generation of entangled qubits by utilizing the properties of edge states appearing at one end of a periodically driven (Floquet) superconducting qubit chain. Such qubits are naturally protected by the system's topology and their manipulation is possible through adiabatic control of the system parameters. By utilizing a Y-junction geometry, we then develop a protocol to perform high-fidelity transfer of entangled qubits from one end to another end of a qubit chain. Our quantum state transfer protocol is found to be robust against disorder and imperfection in the system parameters. More importantly, our proposed protocol also performs remarkably well at larger system sizes due to nonvanishing gaps between the involved edge states and the bulk states, thus allowing us in principle to transfer entangled states over an arbitrarily large distance. This work hence indicates that Floquet topological edge states are not only resourceful for implementing quantum gate operations, but also useful for high-fidelity and long-distance transfer of entangled states along solid-state qubit chains.

description: Based on 14 data points obtained with near-infrared speckle interferometry and covering an almost entire revolution, we present a first visual orbit for the low-mass binary system Gliese 22 AC. The quality of the orbit is largely improved with respect to previous astrometric solutions. The dynamical system mass is 0.592 +- 0.065 solar masses, where the largest part of the error is due to the Hipparcos parallax. A comparison of this dynamical mass with mass-luminosity relations on the lower main sequence and theoretical evolutionary models for low-mass objects shows that both probably underestimate the masses of M dwarfs. A mass estimate for the companion Gliese 22 C indicates that this object is a very low-mass star with a mass close to the hydrogen burning mass limit.

description: As new techniques exploiting the Earth's ambient seismic noise field are developed and applied, such as for the observation of temporal changes in seismic velocity structure, it is crucial to quantify the precision with which wave-type measurements can be made. This work uses array data at the Homestake mine in Lead, South Dakota and an array at Sweetwater, Texas to consider two aspects that control this precision: the types of seismic wave contributing to the ambient noise field at microseism frequencies and the effect of array geometry. Both are quantified using measurements of wavefield coherence between stations in combination with Wiener filters. We find a strong seasonal change between body-wave and surface-wave content. Regarding the inclusion of underground stations, we quantify the lower limit to which the ambient noise field can be characterized and reproduced; the applications of the Wiener filters are about 4 times more successful in reproducing ambient noise waveforms when underground stations are included in the array, resulting in predictions of seismic timeseries with less than a 1\% residual, and are ultimately limited by the geometry and aperture of the array, as well as by temporal variations in the seismic field. We discuss the implications of these results for the geophysics community performing ambient seismic noise studies, as well as for the cancellation of seismic Newtonian gravity noise in ground-based, sub-Hz, gravitational-wave detectors.
title: The Transmission of World Shocks to Emerging-Market Countries: An Empirical Analysis
Creators: name: Desroches, Brigitte
Publisher: name: Bank of Canada
Year: 2004

description: The first step in designing effective policies to stabilize an economy is to understand business cycles. No country is isolated from the world economy and external shocks are becoming increasingly important. The author documents the sources of macroeconomic fluctuations in 22 emerging-market countries, and measures two specific shocks that could be transmitted from one country to another: a world real output shock and a world real interest rate shock. Her analysis shows that there are major differences in the transmission mechanism across emerging-market countries. To assess whether they are due to different economic structures or to the exchange rate regime, she divides the sample into groups of countries. The results indicate that the exchange rate regime is a critical factor, although restrictions on capital flows also play a crucial role. The author also shows that regional groups and trade openness do not play as important a role as the exchange rate regime and capital flows in determining the transmission of business cycles.
description: Pour élaborer des politiques efficaces et stabilisatrices, il importe d'abord de comprendre le cycle économique. Aucun pays n'est coupé de l'économie mondiale, et les chocs externes ont aujourd'hui une influence de plus en plus grande. L'auteure examine les sources des fluctuations macroéconomiques qu'ont connues 22 pays à marché émergent. Elle s'intéresse en particulier à deux chocs mondiaux dont les effets sont susceptibles de se propager entre pays : une variation de la production réelle et une modification des taux d'intérêt réels. Son analyse révèle que le mécanisme de transmission présente des différences importantes d'une économie émergente à l'autre. Aussi l'auteure divise-t-elle son échantillon de pays en plusieurs groupes afin d'établir si ces différences sont attribuables à la structure économique des pays étudiés ou à leur régime de change. Ses résultats indiquent que le choix du régime de change est crucial, encore que les restrictions fixées aux mouvements de capitaux jouent également un rôle déterminant. L'étude montre par ailleurs que les blocs régionaux et l'ouverture des échanges sont des facteurs relativement moins importants dans la transmission des fluctuations cycliques que le régime de change et les mouvements de capitaux.

Au moyen d'une mesure naturelle tirée des données d'entreprises sélectionnées, ils calculent par ailleurs la probabilité de défaillance de chaque entreprise, puis la comparent à celle estimée à l'aide du modèle KMV.

title: Une approche éclectique d'estimation du PIB potentiel pour le Royaume-Uni
Creators: name: St-Arnaud, Charles
Publisher: name: Bank of Canada
Year: 2004

description: The author describes results obtained by using a new methodology to estimate potential output for the United Kingdom. The estimation method, which follows Rennison (2003) and Gosselin and Lalonde (2002), shows that combining the use of a Hodrick-Prescott filter and a structural vector autoregression (SVAR) is optimal to estimating potential output. Using this method, the author estimates two components of U.K. potential output: the full-employment labour input and the trend rate of labour-productivity growth. This type of decomposition is similar to the one used by HM Treasury (2002) and is particularly useful for identifying the source of fluctuations in potential output. The author's results show that growth in potential output was primarily driven by growth in labour productivity over the 1971-2003 period, whereas its volatility is accounted for by the labour-input component. In addition, the author attempts to explain movements in inflation using this new methodology.
description: Dans cette étude, l'auteur présente les principaux résultats de l'application d'une nouvelle méthode d'estimation du PIB potentiel britannique. Cette méthode est fondée sur les travaux de Rennison (2003) et de Gosselin et Lalonde (2002), qui indiquent que l'utilisation conjointe d'un filtre de Hodrick-Prescott et de vecteurs autorégressifs structurels (SVAR) serait optimale pour l'estimation du PIB potentiel. L'auteur utilise cette méthodologie afin d'estimer deux composantes du PIB potentiel britannique : l'intrant travail de plein emploi et la productivité tendancielle de la main-d'oeuvre. Cette décomposition est semblable à celle utilisée par le HM Treasury (2002) et permet de bien identifier les sources de fluctuations du PIB potentiel. Selon les résultats obtenus par l'auteur, la croissance de la productivité de la main-d'oeuvre explique en grande partie la croissance du PIB potentiel au cours de la période 1971-2003. Toutefois, c'est la croissance de l'intrant travail qui explique la volatilité de la croissance du PIB potentiel. De plus, l'auteur montre que l'écart de production obtenu permet d'expliquer l'évolution de l'inflation britannique.

description: We study the kinetics of the isotropic-smectic phase transition in a colloidal rod/polymer mixture by visualizing individual smectic layers. First, we show that the bulk isotropic-smectic phase transition is preceded by a surface freezing transition in which a quasi two-dimensional smectic phase wets the isotropic-nematic interface. Next, we identify a two step kinetic pathway for the formation of a bulk smectic phase. In the first step a metastable isotropic-nematic interface is formed. This interface is wetted by the surface induced smectic phase. In the subsequent step, smectic layers nucleate at this surface phase and grow into the isotropic bulk phase.

Creators: name: Bauer, Gregory

Publisher: name: Bank of Canada
Year: 2004

description: Existing studies using low-frequency data show that macroeconomic shocks contribute little to international stock market covariation. Those studies, however, do not account for the presence of asymmetric information, where sophisticated investors generate private information about the fundamentals that drive returns in many countries. In this paper, the authors use a new microstructure data set to better identify the effects of private and public information shocks about U.S. interest rates and equity returns. High-frequency private and public information shocks help forecast domestic money and equity returns over daily and weekly intervals. In addition, these shocks are components of factors that are priced in a model of the cross-section of international returns. Linking private information to U.S. macroeconomic factors is useful for many domestic and international asset-pricing tests.
description: Les travaux fondés sur l'emploi de données de basse fréquence montrent que les chocs macroéconomiques contribuent peu aux covariations des marchés boursiers internationaux. Ils ne tiennent cependant pas compte de la présence d'une information asymétrique, due au fait que les investisseurs avertis génèrent de l'information privée au sujet des facteurs fondamentaux qui déterminent les rendements dans bon nombre de pays. Bauer et Vega font appel à un nouvel ensemble de données microstructurelles pour mieux cerner l'incidence des chocs d'information privée et publique relatifs aux taux d'intérêt et aux rendements boursiers américains. L'utilisation de données de haute fréquence sur ces chocs aide à prévoir l'évolution quotidienne et hebdomadaire des taux d'intérêt et des rendements boursiers aux États-Unis. En outre, ces chocs s'avèrent l'un des facteurs qui influent sur le prix des actions dans un modèle explicatif du comportement des rendements dans différents pays. La prise en compte de l'information privée que les investisseurs avertis détiennent sur les facteurs macroéconomiques américains permettrait d'améliorer de nombreux tests d'évaluation des actifs nationaux et internationaux.

Year: 2004

description: Zero-coupon interest rates are the fundamental building block of fixed-income mathematics, and as such have an extensive number of applications in both finance and economics. The risk-free government zero-coupon term structure is, however, not directly observable and needs to be generated from the prices of marketable, coupon-bearing bonds. The authors introduce the first public-domain database of constant-maturity zero-coupon yield curves for the Government of Canada bond market. They first outline the mechanics of the curve-fitting algorithm that underlie the model, and then perform some preliminary statistical analysis on the resulting yield curves. The full sample period extends from January 1986 to May 2003; it is broken down into two subsamples, reflecting the structural and macroeconomic changes that impacted the Canadian fixed-income markets over that time. The authors examine the evolution of a number of key interest rates and yield-curve measures over the period, perform a principal-components analysis of the common factors that have influenced yield changes over time, and compare holding-period returns over the sample for assets of various maturities.

Les auteurs présentent ici la première banque de données publique sur les courbes de rendement coupon zéro (échéance constante) des obligations du gouvernement canadien. Ils décrivent d'abord le fonctionnement de l'algorithme d'ajustement à la base de leur modèle, puis effectuent une analyse statistique préliminaire des courbes de rendement obtenues. Leur période d'estimation va de janvier 1986 à mai 2003 et a été divisée en deux afin de tenir compte des changements structurels et macroéconomiques qui ont influé sur les marchés canadiens de titres à revenu fixe durant cet intervalle. Les auteurs examinent ensuite l'évolution de plusieurs taux d'intérêt clés et de certaines caractéristiques des courbes de rendement estimées avant de faire une analyse en composantes principales des facteurs communs ayant façonné le comportement des rendements au fil du temps. Ils comparent aussi les rendements, sur la durée de détention, d'actifs de diverses échéances au cours de l'ensemble de la période considérée.

description: We discuss the origin of an enigmatic low-temperature behavior of one-dimensional decorated spin systems which was coined the pseudo-transition. Tracing out the decorated parts results in the standard Ising-chain model with temperature-dependent parameters and the unexpected low-temperature behavior of thermodynamic quantities and correlations of the decorated spin chains can be tracked down to the critical point of the standard Ising-chain model at ${\sf H}=0$ and ${\sf T}=0$. We illustrate this perspective using as examples the spin-1/2 Ising-XYZ diamond chain, the coupled spin-electron double-tetrahedral chain, and the spin-1/2 Ising-Heisenberg double-tetrahedral chain.

[TL: Italy, Calabria, Aspromonte, 1400 m]; this form was described on page 222 and the uppersides figured on tav. II figs 4 11 and 5 00, from which it appears to be a fairly heavily marked form, hence Verity’s suggestion that the ab. totila of Stauder (see above) equated to this subspecies. The undersides were not figured by Turati but the forewing apices appear rounded as in M. ornata. According to CONCI & POGGI (1996) the collection of E. Turati is in the Museo Regionale di Scienze Naturali, Torino, Italy, (MRSN). NEKRUTENKO (1993: 129) listed the type material of Turati in this museum and referring to this subspecies stated that there were two female syntypes from the Aspromonte Mountains in the Province of Reggio Calabria, Italy and identified them as Melitaea phoebe, being unaware of the specific separation of M. ornata.
Unfortunately, the entomology collections in the Turin Museum are not currently accessible for administrative reasons and it has not been possible to inspect type material. However, it is possible to make a speculative identification, based on current knowledge of the distributions of the two species. Based on the collecting locality, this subspecies is almost certainly M. ornata as M. phoebe sensu strictu has not been recorded this far south in peninsular Italy; its limit appears to be Calabria, Cosenza, Monte Martinelli (RUSSELL & PATEMAN, 2011), where M. ornata also occurs. Six males and one female of this subspecies are present in the Rothschild collection in the Natural History Museum London (Russell and Tennent, pers obs.). This taxon was not considered by VAN OORSCHOT & COUTSIS (2014) but RUSSELL & TENNENT (2016: 51, note 67) suggested it was M. ornata because of its location in southern peninsular Italy.

description: The Grey Falcon (Falco hypoleucos) is a desert-living species restricted to the dry centre of Australia. These falcons have a number of unique life-history adaptations that may be crucial for their survival in this harsh environment, but these may, conversely, confine them to these arid regions. In this study we investigated what Grey Falcon feather structure can reveal about the ecology of the species. Specifically, we tested UV reflectance and structural waterproofing of Grey Falcon feathers, and compared these properties across other Australian Falco species. Grey Falcon feathers did not reflect unique UV peaks, nor show any significant difference in structural waterproofing when compared with closely-related sympatric falcon species. This suggests that Grey Falcon feathers have no specific adaptations to prevent the impact of UV or water on their plumage, so feather structure evidently does not help explain the persistence of this species in arid Australia. We suggest that an exploration of the physiological and behavioural thermoregulatory capabilities of this species should provide further insights in understanding how these birds cope with their extreme environment and are confined there.

description: In this paper, we develop the theory of singular hermitian metrics on vector bundles. As an application, we give a structure theorem of a projective manifold $X$ with pseudo-effective tangent bundle: $X$ admits a smooth fibration $X \to Y$ to a flat projective manifold $Y$ such that its general fiber is rationally connected. Moreover, by applying this structure theorem, we classify all the minimal surfaces with pseudo-effective tangent bundle and study general non-minimal surfaces, which provide examples of (possibly singular) positively curved tangent bundles.

On reducing Terrorism Power: A Hint from Physics

description: The September 11 attack on the US has revealed an unprecedented terrorism worldwide range of destruction. Recently, it has been related to the percolation of worldwide spread passive supporters. This scheme puts the suppression of the percolation effect as the major strategic issue in the fight against terrorism. Accordingly the world density of passive supporters should be reduced below the percolation threshold. In terms of solid policy, it means to neutralize millions of random passive supporters, which is contrary to ethics and out of any sound practical scheme. Given this impossibility we suggest instead a new strategic scheme to act directly on the value of the terrorism percolation threshold itself without harming the passive supporters. Accordingly we identify the space hosting the percolation phenomenon to be a multi-dimensional virtual social space which extends the ground earth surface to include the various independent terrorist-fighting goals. The associated percolating cluster is then found to create long-range ground connections to terrorism activity. We are thus able to modify the percolation threshold pc in the virtual space to reach p

description: We report the discovery, by the Chandra X-ray Observatory, of X-ray emission from the bipolar planetary nebula Menzel 3. In Chandra CCD imaging, Mz 3 displays hot (3-6x10^6 K) gas within its twin, coaxial bubbles of optical nebulosity, as well as a compact X-ray source at the position of its central star(s). The brightest diffuse X-ray emission lies along the polar axis of the optical nebula, suggesting a jet-like configuration. The observed combination of an X-ray-emitting point source and possible X-ray jet(s) is consistent with models in which accretion disks and, potentially, magnetic fields shape bipolar planetary nebulae via the generation of fast, collimated outflows.

description: We present a comprehensive study and evaluation of existing single image compression artifacts removal algorithms, using a new 4K resolution benchmark including diversified foreground objects and background scenes with rich structures, called Large-scale Ideal Ultra high definition 4K (LIU4K) benchmark. Compression artifacts removal, as a common post-processing technique, aims at alleviating undesirable artifacts such as blockiness, ringing, and banding caused by quantization and approximation in the compression process. In this work, a systematic listing of the reviewed methods is presented based on their basic models (handcrafted models and deep networks). The main contributions and novelties of these methods are highlighted, and the main development directions, including architectures, multi-domain sources, signal structures, and new targeted units, are summarized. Furthermore, based on a unified deep learning configuration (i.e. same training data, loss function, optimization algorithm, etc.), we evaluate recent deep learning-based methods based on diversified evaluation measures. The experimental results show the state-of-the-art performance comparison of existing methods based on both full-reference, non-reference and task-driven metrics. Our survey would give a comprehensive reference source for future research on single image compression artifacts removal and inspire new directions of the related fields.
