description: Understanding and prediction of the chemical reactions are fundamental demanding in the study of many complex chemical systems. Reactive molecular dynamics (MD) simulation has been widely used for this purpose as it can offer atomic details and can help us better interpret chemical reaction mechanisms. In this study, two reference datasets were constructed and corresponding neural network (NN) potentials were trained based on them. For given large-scale reaction systems, the NN potentials can predict the potential energy and atomic forces of DFT precision, while it is orders of magnitude faster than the conventional DFT calculation. With these two models, reactive MD simulations were performed to explore the combustion mechanisms of hydrogen and methane. Benefit from the high efficiency of the NN model, nanosecond MD trajectories for large-scale systems containing hundreds of atoms were produced and detailed combustion mechanism was obtained. Through further development, the algorithms in this study can be used to explore and discovery reaction mechanisms of many complex reaction systems, such as combustion, synthesis, and heterogeneous catalysis without any predefined reaction coordinates and elementary reaction steps.

 Material Examined. Bahamas: Long Island, Stella Maris 28.ix.1988, at light, L. D. Miller and M. J. Simon, Acc. No. 1988-73 (1 male, slide DM 536).
 Diagnosis. Wingspan 14.0–23.5. Forewings light buff or beige throughout or with area between veins Sc and radius with ecru or brownish gray scaling in fresh specimens. Within forewing lobes, veins R 5, M 3, Cu 1, and Cu 2, likewise traced with darker brownish gray scaling in fresh specimens. Hindwings brownish gray, body. Antennae, legs, and body light buff. Head with brownish gray to ochraceous basal scales. Abdomen with longitudinal brownish gray middorsal and subdorsal lines.
 Life History. Larvae are stem and shoot borers of Eupatorium capillifolium (Lam.) Small. This plant occurs throughout most of the Bahamas archipelago, except for the extreme southeastern portion (Great Inagua, Turks and Caicos) (Correll and Correll 1982). Young larvae feed in the shoots but re-enter the lower stem and roots as they mature. As in H. chlorias, reddish longitudinal bands may be present and the circular anal plate bears a pair of thorn-like projections. The larvae are distinct from the latter species in having a patterned head with the sculpted adfrontal sclerites and epicranial suture bordered by a contrasting pale, smooth area (Matthews 2006). As in H. chlorias, larvae pupate within the stem gallery.
 Distribution. Bahamas: Long Island; United States: Florida, Kansas, Louisiana, Mississippi, North Carolina, and Texas.
 Comments. The diagnosis is based primarily on Florida specimens. The Long Island specimen is worn and bears only faint markings. The left valve saccular process is somewhat variable but within the range of variation seen in Florida specimens. In Florida, E. compositifolium Walter is an occasional host and additional hosts are used in the western states (Matthews and Lott 2005).

Pulse-to-pulse intensity modulation and drifting subpulses in recycled pulsars

description: We report the detection of pulse-to-pulse periodic intensity modulations, in observations of recycled pulsars. Even though the detection of individual pulses was generally not possible due to their low flux density and short duration, through the accumulation of statistics over sequences of 10^5--10^6 pulses we were able to determine the presence and properties of the pulse-to-pulse intensity variations of six pulsars. In most cases we found that the modulation included a weak, broadly quasi-periodic component. For two pulsars the sensitivity was high enough to ascertain that the modulation phase apparently varies systematically across the profile, indicating that the modulation appears as drifting subpulses. We detected brighter than average individual pulses in several pulsars, with energies up to 2--7 times higher than the mean, similar to results from normal pulsars. We were sensitive to giant pulses of a rate of occurrence equal to (and in many instances much lower than) that of PSR B1937+21 at 1400 MHz (~30 times lower than at 430 MHz), but none were detected, indicating that the phenomenon is rare in recycled pulsars.

All Transparent Conservation Scheme for the Menokin Ruins
Creators: name: Lowe, E.
Publisher: name: Challenging Glass Conference Proceedings
Year: 2010

description: The challenge of preserving the 18th century ruin at Menokin, Virginia USA, has inspired a radical scheme to authentically conserve the surviving architecture. The ruined building is in a state of decay and Dewhurst Macfarlane & Partners have designed a glass structure to re-establish the protection of the building envelope. The plans presented are not ready for construction. Details for splicing together timber and glass beams are discussed. The conservators plans to recreate the missing elements in glass has led to the development of an all transparent structural system. The paper discusses how the properties of acrylic and glass can be combined to create composite elements that are sufficiently versatile to meet the demands of reconstructing 18th century building elements.

title: Steps in Applying Extreme Value Theory to Finance: A Review
Creators: name: Bensalah, Younes
Publisher: name: Bank of Canada
Year: 2000

description: Extreme value theory (EVT) has been applied in fields such as hydrology and insurance. It is a tool used to consider probabilities associated with extreme and thus rare events. EVT is useful in modelling the impact of crashes or situations of extreme stress on investor portfolios. Contrary to value-at-risk approaches, EVT is used to model the behaviour of maxima or minima in a series (the tail of the distribution). However, implementation of EVT faces many challenges, including the scarcity of extreme data, determining whether the series is "fat-tailed," choosing the threshold or beginning of the tail, and choosing the methods of estimating the parameters. This paper focuses on the univariate case; the approach is not easily extended to the multivariate case, because there is no concept of order in a multidimensional space and it is difficult to define the extremes in the multivariate case. Following a review of the theoretical literature, univariate EVT techniques are applied to a series of daily exchange rates of Canadian/U.S. dollars over a 5-year period (1995-2000).
description: Appliquée dans des domaines aussi divers que l'hydrologie et l'assurance, la théorie des valeurs extrêmes permet d'estimer la probabilité associée à des événements extrêmes, donc rares. Aussi cet outil peut-il servir à modéliser l'incidence de krachs boursiers ou de tensions extrêmes sur les portefeuilles des investisseurs. Contrairement aux méthodes fondées sur la valeur exposée au risque, la théorie des valeurs extrêmes permet de reproduire le comportement des maxima ou des minima d'une série (les queues de la distribution). Son application soulève cependant de nombreuses difficultés : les occurrences extrêmes sont par définition rares, et il faut établir dès le départ si les queues de la distribution sont épaisses ainsi que choisir le seuil (ou début de la queue) et les méthodes d'estimation des paramètres. L'auteur se limite au cas univarié, car la théorie en question se prête mal à l'étude du cas multivarié en raison de l'absence de notion d'ordre dans un espace multidimensionnel et du problème que pose la définition des extrêmes lorsqu'il y a plusieurs variables. Après avoir effectué une revue de la littérature, l'auteur applique des techniques univariées s'inspirant de cette théorie à la série des taux de change quotidiens Canada/États-Unis pour les années 1995-2000.

description: This paper investigates the non-linear adjustments between maize and beans markets in the highlands of central Kenya. Results are based on bi-weekly retail price data collected from ten markets in Mbeere and Meru south districts. The error correction model extended by the incorporation of asymmetric adjustment terms was used to study asymmetry in price transmission between the markets. Cointegration technique was used to determine the existence of a long-run price relationship between the maize and beans markets. The findings indicate that the markets are integrated. Retail price transmission process between the markets is asymmetric. The observed prices adjust more rapidly to increases in prices than to decreases. The speed of price response between market pairs was higher for markets that are far apart.

description: Particles dispersed in a liquid crystal above the nematic-isotropic phase transition are wetted by a surface-induced corona of paranematic order. Such coronas give rise to pronounced two-particle interactions. In this article, we report details on the analytical and numerical study of these interactions published recently [Phys. Rev. Lett. 86, 3915 (2001)]. We especially demonstrate how for large particle separations the asymptotic form of a Yukawa potential arises. We show that the Yukawa potential is a surprisingly good description for the two-particle interactions down to distances of the order of the nematic coherence length. Based on this fact, we extend earlier studies on a temperature induced flocculation transition in electrostatically stabilized colloidal dispersions [Phys. Rev. E 61, 2831 (2000)]. We employ the Yukawa potential to establish a flocculation diagram for a much larger range of the electrostatic parameters, namely the surface charge density and the Debye screening length. As a new feature, a kinetically stabilized dispersion close to the nematic-isotropic phase transition is found.

title: Les effets réels du cours des actions sur la consommation
Creators: name: Pichette, Lise
Publisher: name: Bank of Canada
Year: 2000

description: Au cours des années 1990, les marchés financiers nord-américains ont été marqués par une hausse notable des indices boursiers. De plus, le nombre de ménages qui détiennent des actions a augmenté de façon significative. Si la richesse boursière influence les décisions des consommateurs, la hausse du cours des actions a eu un impact appréciable sur la consommation des ménages ces dernières années. L'objectif de la présente étude est d'examiner la relation entre la valeur des actions et la consommation globale. L'approche utilisée pour estimer cette relation est un modèle à correction d'erreurs, et l'échantillon porte sur des données canadiennes allant du premier trimestre de 1965 au quatrième trimestre de 1998. Les résultats montrent que les fluctuations de la richesse boursière ont un effet significatif (environ 3 % du changement de la valeur des actions) sur la consommation à long terme. Les variations à court terme du prix des actions accélèrent l'ajustement vers l'équilibre de long terme des dépenses des ménages.
description: During the nineties, stock prices increased remarkably. The number of households owning stocks also rose considerably. If stock market wealth has an effect on consumers' decisions, then the rise in equity prices could have contributed to the growth in consumption in recent years. This paper examines the wealth effect resulting from an increase in the value of equity on aggregate consumption. To estimate this relationship, an error correction model has been chosen. Using Canadian data for the sample period first quarter of 1965 to the fourth quarter of 1998, the results show that fluctuations in equity prices have a statistically significant long-run effect on consumption (about 3 per cent of the asset prices change). Short-term variations seem to accelerate the adjustment of household spending to its long-term equilibrium.

Publisher: name: Bank of Canada

description: L'écart relatif de productivité entre le Canada et les États-Unis est redevenu ces derniers temps un sujet controversé. Selon certains, une des causes de cet écart relatif serait la dépréciation graduelle qu'enregistre le taux de change depuis plus de 20 ans. Ainsi, la hausse du taux de change rendrait artificiellement les firmes canadiennes plus compétitives, ce qui tendait à diminuer les incitatifs de celles-ci à être plus productives. Notre objectif est d'étudier les liens empiriques entre ces variables afin de voir si cette conjecture se reflète dans les données.
description: The relative productivity gap between Canada and the United States is a controversial subject matter. One argument especially contentious in this debate stems from the belief that the gradual depreciation of the Canadian dollar over the last 20 years has been one of the determinants of the productivity gap. In fact, the exchange rate depreciation seems to have artificially improved Canadian firms' productivity, which tends to inhibit their incentive to better productivity. One of our objectives will be to study the empirical link between these variables in order to determine whether this assumption is verified empirically.
A non-realization theorem in the context of Descartes' rule of signs

description: For a real degree $d$ polynomial $P$ with all nonvanishing coefficients, with $c$ sign changes and $p$ sign preservations in the sequence of its coefficients ($c+p=d$), Descartes' rule of signs says that $P$ has $pos\leq c$ positive and $neg\leq p$ negative roots, where $pos\equiv c($\, mod $2)$ and $neg\equiv p($\, mod $2)$. For $1\leq d\leq 3$, for every possible choice of the sequence of signs of coefficients of $P$ (called sign pattern) and for every pair $(pos, neg)$ satisfying these conditions there exists a polynomial $P$ with exactly $pos$ positive and $neg$ negative roots (all of them simple); that is, all these cases are realizable. This is not true for $d\geq 4$, yet for $4\leq d\leq 8$ (for these degrees the exhaustive answer to the question of realizability is known) in all nonrealizable cases either $pos=0$ or $neg=0$. It was conjectured that this is the case for any $d\geq 4$. For $d=9$, we show a counterexample to this conjecture: for the sign pattern $(+,-,-,-,-,+,+,+,+,-)$ and the pair $(1,6)$ there exists no polynomial with $1$ positive, $6$ negative simple roots and a complex conjugate pairs and, up to equivalence, this is the only case for $d=9$.

description: The structures of long-range ordered physisorbed monolayer on a carbon nanotube are examined. Geometrical and energetical constraints determining the order of such monolayers are discussed. A number of symmetrically different, strongly bound adsorbate structures is found for Xe adsorbates, some of which differ very little in energy. The presented results suggest that the atomically uniform coating of carbon nanotubes is possible and offer a clear visualization of such coatings.

title: The Application of Artificial Neural Networks to Exchange Rate Forecasting: The Role of Market Microstructure Variables
Creators: name: Gradojevic, Nikola
name: Yang, Jing
Publisher: name: Bank of Canada
Year: 2000

description: Artificial neural networks (ANN) are employed for high-frequency Canada/U.S. dollar exchange rate forecasting. ANN outperform random walk and linear models in a number of recursive out-of- sample forecasts. The inclusion of a microstructure variable, order flow, substantially improves the predictive power of both the linear and non-linear models. Two criteria are applied to evaluate model performance: root-mean squared error (RMSE) and the ability to predict the direction of exchange rate moves. ANN is consistently better in RMSE than random walk and linear models for the various out-of-sample set sizes. Moreover, ANN performs better than other models in terms of percentage of correctly predicted exchange rate changes (PERC). The empirical results suggest that optimal ANN architecture is superior to random walk and any linear competing model for high-frequency exchange rate forecasting.
description: Les réseaux de neurones artificiels sont employés pour la prévision du taux de change Canada/ États-Unis à fréquence élevée. Ils produisent généralement de meilleures prévisions hors échantillon récursives qu'une marche aléatoire ou un modèle linéaire. L'addition d'une variable microstructurelle (le flux des transactions) entraîne une nette amélioration de la capacité de prévision des modèles tant linéaires que non linéaires. Les auteurs font appel à deux critères pour évaluer le rendement d'un modèle : la racine carrée de l'erreur quadratique moyenne (REQM) et la capacité de prévoir le sens des variations du taux de change. La REQM est systématiquement moins élevée dans le cas des prévisions produites par les réseaux de neurones artificiels que pour celles issues d'une marche aléatoire ou de modèles linéaires, peu importe le nombre d'observations hors échantillon. De plus, les réseaux de neurones artificiels permettent de prédire correctement le sens d'un plus grand pourcentage des variations du taux de change. Selon les résultats empiriques, l'architecture optimale de ces réseaux fournit de meilleures prévisions du taux de change à fréquence élevée qu'une marche aléatoire ou tout autre modèle linéaire.

description: The TKTS booth in Times Square, New York, is a 250m2 all glass public amphitheater, with seating for 500 people. Its all glass load path includes treads, rafters and the 4.9m tall SentryGlas laminated walls. The 9.1m long beams were spliced using the overlap method with pins. The glass walls hold the full weight of the structure above, and in the real world environment of Times Square there are many possible causes of sudden failure including vehicle impact. A redundancy system was developed that accounts for the complete loss of one or two panels. In order to eliminate the need for metal lateral bracing, the treads were structurally siliconed to the rafters. A number of tests were conducted to confirm the validity of design concepts. This paper reviews the structural concepts behind the design, the fabrication methods, and the testing that was completed.

title: Long-Term Determinants of the Personal Savings Rate: Literature Review and Some Empirical Results for Canada
Creators: name: Bérubé, Gilles
name: Côté, Denise
Publisher: name: Bank of Canada
Year: 2000

description: This paper examines the structural determinants of the personal savings rate in Canada over the last 30 years, using cointegration techniques. The main finding is that the real interest rate, expected inflation, the ratio of the all-government fiscal balances to nominal GDP, and the ratio of household net worth to personal disposable income are the most important determinants of the trend in the personal savings rate, as measured in the National Income and Expenditure Accounts (NIEA). The results also suggest that the rapid decline in the NIEA personal savings rate in recent years largely reflects a change in the trend component of the savings rate, rather than a transitory departure from the trend. In the current environment of low inflation and government fiscal balances moving into surpluses, the trend NIEA savings rate could remain low. When using a measure of the personal savings rate based on the change in the net worth position of the personal sector (as estimated in the National Balance Sheet Accounts [NBSA]), the trend is determined by the real interest rate, expected inflation, and the ratio of household net worth to personal disposable income. However, the statistical evidence supporting this long-run relationship is not as conclusive as that for the NIEA savings rate.
description: Au moyen de techniques de cointégration, les auteurs étudient les déterminants structurels de l'évolution du taux d'épargne des particuliers au Canada au cours des trente dernières années. Leur principale conclusion est que le taux d'intérêt réel, l'inflation attendue, le ratio du solde budgétaire de l'ensemble du secteur public au PIB nominal et le ratio de l'avoir net des ménages à leur revenu disponible constituent les principaux déterminants de l'évolution à long terme du taux d'épargne des particuliers mesuré dans les comptes nationaux des revenus et des dépenses. Selon les résultats obtenus par les auteurs, la baisse rapide que ce taux d'épargne connaît depuis quelques années refléterait essentiellement une modification de la composante tendancielle du taux d'épargne plutôt qu'un écart transitoire par rapport à la tendance. Dans le contexte actuel, caractérisé par un bas taux d'inflation et l'apparition d'excédents budgétaires, il se pourrait que cette mesure du taux d'épargne tendanciel demeure faible. Si les auteurs utilisent plutôt une mesure fondée sur la variation de l'avoir net du secteur des particuliers (estimée à l'aide des comptes du bilan national), les déterminants de l'évolution tendancielle du taux d'épargne sont alors le taux d'intérêt réel, l'inflation attendue et le ratio de l'avoir net des ménages à leur revenu disponible. Toutefois, les résultats statistiques obtenus à l'appui de cette relation à long terme ne sont pas aussi concluants que dans le cas du taux d'épargne mesuré dans les comptes nationaux des revenus et des dépenses.

description: L'objectif des auteurs est ici de voir dans quelle mesure des facteurs autres que les prix des produits de base et de l'énergie ont contribué à la dépréciation du dollar canadien depuis le début des années 1970. Les variables prises en compte à cette fin incluent entre autres les conditions budgétaires et la productivité. La méthode utilisée consiste à déterminer les variables susceptibles de jouer un rôle important, à long terme, dans l'évolution du taux de change réel. Ils arrivent à la conclusion que même si le rythme d'accroissement de l'endettement au Canada a contribué à la dépréciation du dollar canadien vis-à-vis du dollar américain, il ne peut expliquer que 20 % de celle enregistrée durant les années 1990.
description: This paper explores the extent to which factors other than commodity and energy prices may have contributed to the Canadian dollar's depreciation since the early 1970s. The variables considered include among others budgetary conditions and productivity. The approach involves a long-term determination, using cointegration methodology, of variables that may have played a major role in the behaviour of the real exchange rate. The authors conclude that, while growing indebtedness in Canada has contributed to the Canadian currency's depreciation against the U.S. dollar, it explains only 20 per cent of that decline during the 1990s.

description: In cold core of dark molecular clouds, where the UV radiation from external sources is strongly attenuated, cosmic rays can induce chemical reactions on the surface of ice-covered grains promoting the ejection of the processed material to the gas phase. We report the positive and negative secondary ion emission from pure CH3CN, C2H3CN and i-C3H7CN ices due to the bombardment of heavy ions (252Cf fission fragments), simulating the incidence of cosmic rays onto icy surfaces. The secondary ions emitted from each sample were analysed by time-of-flight mass spectrometry (TOF-MS), using Plasma Desorption Mass Spectrometry (PDMS) technique. Several ionic species were identified, indicating strong fragmentation on the frozen surface. Proton-transfer processes are suggested to play a role for positive ion desorption, as evidenced by the protonated RCNH+ parent molecules and (RCN)nH+ ionic clusters. The high electron affinity of the cyano radical seems to contribute to the strong emission of CN-, as well as anions attributed to the CHmCN- fragment and (RCN)nCN- cluster series. Sputtering and desorption of ion clusters (positive and negative) induced by heavy ion bombardment are suggested to constitute a route by which new neutral or ionised molecular species may be delivered to the gas phase where thermal desorption is negligible.

description: We present RGS data from an XMM-Newton observation of the Seyfert 1 galaxy NGC 3516, taken while the continuum source was in an extreme low state. The spectrum shows numerous emission lines including the H-like lines of C, N and O and the He-like lines of N, O and Ne. These data show that the N lines are far stronger than would be expected from gas of solar abundances. Based on our photoionization models, we find that N is overabundant compared to C, O and Ne by at least a factor of 2.5. We suggest this is the result of secondary production of N in intermediate mass stars, and indicative of the history of star formation in NGC 3516.

description: In this paper, we develop a concise but efficient network architecture called linear compressing based skip-connecting network (LCSCNet) for image super-resolution. Compared with two representative network architectures with skip connections, ResNet and DenseNet, a linear compressing layer is designed in LCSCNet for skip connection, which connects former feature maps and distinguishes them from newly-explored feature maps. In this way, the proposed LCSCNet enjoys the merits of the distinguish feature treatment of DenseNet and the parameter-economic form of ResNet. Moreover, to better exploit hierarchical information from both low and high levels of various receptive fields in deep models, inspired by gate units in LSTM, we also propose an adaptive element-wise fusion strategy with multi-supervised training. Experimental results in comparison with state-of-the-art algorithms validate the effectiveness of LCSCNet.

Year: 2010

description: A new glass-steel roof for an auditorium of the “ex Sala Contrattazioni” in Cuneo (I) was built in 2009, with a design resulted winner of an architectural concourse. The construction, despite the small dimension, is the result of a design process that involved many interdisciplinary professionals, from architectural conception to the construction phase. The main structure has a non-conventional behavior and the steel girders support the curved glass panes with point devices. This article offers an overview of the design criteria, news on technological solutions, and unusual construction methods applied to this particular application.

Design and construction of an all glass cube for the Raaks project in Haarlem (NL)
Creators: name: Nijsse, R.
Publisher: name: Challenging Glass Conference Proceedings
Year: 2010

description: On a square in the old city center of Haarlem (NL) on top of an underground car park garage a glass entrance building was designed by architect Kraayvanger Urbis. ABT/ Rob Nijsse developed the all glass structure for this spectacular building. The fact that the stability was provided by the roof in combination with the four walls of the project makes it something special. Also the application of full glass rods in the structure of the roof is an innovation in the world of making glass structures.

description: We derive the lower bound of uncertainty relations of two unitary operators for a class of states based on the geometric-arithmetic inequality and Cauchy-Schwarz inequality. Furthermore, we propose a set of uncertainty relations for three unitary operators. Compared to the known bound introduced in Phys.Rev.A.100,022116(2019), the unitary uncertainty relations bound with our method is tighter, to a certain extent. Meanwhile, some examples are given in the paper to illustrate our conclusions.
title: Estimating the Fractional Order of Integration of Interest Rates Using a Wavelet OLS Estimator
Creators: name: Tkacz, Greg
Publisher: name: Bank of Canada
Year: 2000

description: The debate on the order of integration of interest rates has long focused on the I(1) versus I(0) distinction. In this paper, we use instead the wavelet OLS estimator of Jensen (1999) to estimate the fractional integration parameters of several interest rates for the United States and Canada from 1948 to 1999. We find that most rates are mean-reverting in the very long run, with the fractional order of integration increasing with the term to maturity. The speeds of mean-reversion are lower in Canada, due likely to a positive country-specific risk premium. We also demonstrate that yield spreads contain noticeable persistence, indicating that these are also not strict I(0) processes. The consequences of these findings are that shocks to most interest rates and their spreads are very long-lasting, yet not necessarily infinite.
description: Le débat entourant l'ordre d'intégration des taux d'intérêt est depuis longtemps centré sur l'opposition I(1)-I(0). Dans cette étude, l'auteur a recours à l'estimateur des moindres carrés ordinaires à ondelettes de Jensen (1999) pour estimer le paramètre d'intégration fractionnaire de divers taux d'intérêt canadiens et américains sur la période allant de 1948 à 1999. Il constate que la plupart des taux reviennent à la moyenne à très long terme et que l'ordre d'intégration fractionnaire augmente avec l'éloignement de l'échéance. Le retour à la moyenne est plus lent au Canada, probablement en raison de la présence d'une prime de risque-pays positive. L'auteur démontre également que les écarts de rendement affichent une persistance notable, ce qui donne à penser qu'eux non plus ne constituent pas de véritables processus intégrés d'ordre zéro. Si l'on en croit ces résultats, les chocs imprimés à la plupart des taux d'intérêt de même qu'aux écarts entre ceux-ci ont des effets très persistants, mais pas forcément de durée illimitée.

description: Thin film transistors (TFTs) made of transparent channel semiconductors such as ZnO are of great technological importance, because their insensitivity to visible light makes device structures simple. In fact, several demonstrations are made on ZnO TFT achieving reasonably good field effect mobilities of 1-10 cm2/Vs, but reveal insufficient device performances probably due to the presence of dense grain boundaries. We have modeled grain boundaries in ZnO thin film transistors (TFTs) and performed device simulation using a two-dimensional device simulator for understanding the grain boundary effects on the device performance. Actual polycrystalline ZnO TFT modeling is commenced with considering a single grain boundary in the middle of the TFT channel formulating with a Gaussian defect distribution localized in the grain boundary. A double Shottky barrier is formed in the grain boundary and its barrier height are analyzed as functions of defect density and gate bias. The simulation is extended to the TFTs with many grain boundaries to quantitatively analyze the potential profiles developed along the channel. One of the big contrasts of polycrystalline ZnO TFT compared with a polycrystalline Si TFT is that much smaller nanoscaled grain size induces heavy overlap of double Shottky barriers. Through the simulation, we can estimate the total trap state density localized in the grain boundaries for a polycrystalline ZnO by knowing apparent mobility and grain size in the device.

title: Some Explorations, Using Canadian Data, of the S-Variable in Akerlof, Dickens, and Perry (1996)
Creators: name: Hogan, Seamus

description: A number of authors have suggested that economies face a long-run inflation-unemployment trade-off due to downward nominal-wage rigidity. This theory has implications for the nature of the short-run Phillips curve when wage inflation is low. Akerlof, Dickens and Perry have developed an empirical model in which a variable (S) designed to capture the effect of downward nominal-wage rigidity is constructed as part of the estimation of the short-run Phillips curve. Adding this variable dramatically improves the dynamic out-of-sample inflation forecasts of the curve in both the United States and Canada.

In this paper we perform a variety of tests using both real and constructed data to address whether the addition of S truly does provide a better estimate of the short-run Phillips curve, and whether this constitutes evidence that downward nominal-wage rigidity increases the natural rate of unemployment in times of low wage inflation. Our main conclusion is that the performance of the S-enhanced Phillips curve in dynamic simulations is independent of whether downward nominal-wage rigidity is an important feature of the macroeconomy.
description: Selon plusieurs auteurs, les économies seraient aux prises avec un arbitrage entre l'inflation et le chômage à long terme en raison de la rigidité à la baisse des salaires nominaux. La nature de la courbe de Phillips à court terme s'en trouverait alors modifiée en période de faible hausse des salaires. Akerlof, Dickens et Perry ont mis au point un modèle empirique dans lequel une variable (appelée S) destinée à saisir l'incidence de la rigidité des salaires nominaux est intégrée à l'estimation de la courbe de Phillips à court terme. L'insertion de cette variable permet d'améliorer considérablement les prévisions dynamiques de l'inflation produites par la courbe de Phillips au delà de la période d'estimation, tant pour les États-Unis que pour le Canada.

Dans leur étude, Seamus Hogan et Lise Pichette appliquent un éventail de tests à des données réelles et artificielles en vue d'établir si l'addition de la variable S donne lieu effectivement à une amélioration de l'estimation de la courbe de Phillips à court terme et si cette amélioration, le cas échéant, indique que la rigidité à la baisse des salaires nominaux fait augmenter le taux de chômage naturel en période de faible progression des salaires. Les auteurs concluent que le pouvoir de prévision de la courbe de Phillips augmentée de S en simulation dynamique ne varie pas selon qu'il y ait ou non rigidité des salaires nominaux dans l'économie.
title: Non-Parametric and Neural Network Models of Inflation Changes
Creators: name: Tkacz, Greg

description: Previous studies have shown that interest rate yield spreads contain useful information about future changes in inflation. However, such studies have for the most part focused on linear models, ignoring potential non-linearities between interest rates and inflation. Using two different non-linear models, we find that the relationship between interest rate yield spreads and inflation changes for policy-relevant horizons in the United States is most pronounced at negative long-short yield spreads, and almost non-existent at positive values of the spread. These findings are consistent with studies noting asymmetric effects of monetary policy on the real economy.
description: Les travaux antérieurs ont montré que les écarts de taux de rendement fournissent une information utile sur l'évolution future de l'inflation. Ces travaux étaient toutefois fondés pour la plupart sur des modèles linéaires et faisaient fi de la non-linéarité possible de la relation entre les taux d'intérêt et l'inflation. Dans cette nouvelle étude, l'auteur a recours à deux modèles non linéaires différents. Il constate que la relation entre les écarts de taux de rendement et les variations de l'inflation dans le cas des horizons de prévision pertinents pour la conduite de la politique monétaire aux États-Unis est au plus fort lorsque les écarts entre taux longs et taux courts sont négatifs et qu'elle est presque nulle lorsqu'ils sont positifs. Ces résultats sont conformes à ceux obtenus par d'autres auteurs qui ont souligné les effets asymétriques de la politique monétaire sur l'économie réelle.
All-Glass Dome for Mosque in Haarlem

description: The architect Fedde Reeskamp, from the ‘Architectenkamer’ in Haarlem had designed a mosque for the client ‘Islamitische Stichting Nederland Selimiye’ in Haarlem. The design consists of a blockwork mosque with a dome on top, visually apparent in silhouette of the mosque. He came with this enquiry for a dome to Octatube. The contrast between the solid building block-shape and the dome on top led to the suggestion to have the dome made in glass, out of its extreme contrast. Octatube designed a self-supporting dome of solely insulated glass panels, without any frame or structure. Thanks to a hidden tensile system with corner joints, the complete dome is a reliable structure of glass and tensile spokes.
