Publisher: name: Challenging Glass Conference Proceedings
Year: 2020

description: Square One Shopping Centre is owned by Oxford Properties in Toronto, Canada, and was designed by MMC International Architects Ltd. The shopping centre went through a recent expansion and features a large glass and steel rotunda for its feature entrance into the new expansion. The feature glass wall is oval in plan and is 18m tall utilizing a custom splicing detail to minimize the use of steel at the connections. The fin wall was analysed and tested to ensure the connection detail behaved as predicted. This paper will visit the design of the fin wall and review the findings of the physical testing performed on the connection detail.

description: In this study, we investigate in detail the photospheric magnetic structure of 98 coronal holes using line-of-sight magnetograms of SDO/HMI, and for a subset of 42 coronal holes using HINODE/SOT G-band filtergrams. We divided the magnetic field maps into magnetic elements and quiet coronal hole regions by applying a threshold at $\pm 25$ G. We find that the number of magnetic bright points in magnetic elements is well correlated with the area of the magnetic elements (cc=$0.83\pm 0.01$). Further, the magnetic flux of the individual magnetic elements inside coronal holes is related to their area by a power law with an exponent of $1.261\pm 0.004$ (cc=$0.984\pm 0.001$). Relating the magnetic elements to the overall structure of coronal holes, we find that on average ($69\pm 8$) % of the overall unbalanced magnetic flux of the coronal holes arises from long-lived magnetic elements with lifetimes > 40 hours. About ($22\pm 4$) % of the unbalanced magnetic flux arises from a very weak background magnetic field in the quiet coronal hole regions with a mean magnetic field density of about 0.2 to 1.2 G. This background magnetic field is correlated to the flux of the magnetic elements with lifetimes of > 40 h (cc=$0.88\pm 0.02$). The remaining flux arises from magnetic elements with lifetimes < 40 hours. By relating the properties of the magnetic elements to the overall properties of the coronal holes, we find that the unbalanced magnetic flux of the coronal holes is completely determined by the total area that the long-lived magnetic elements cover (cc=$0.994\pm 0.001$).

description: In this second paper on the investigation of extraplanar diffuse ionized gas in nearby edge-on spiral galaxies we present the actual results of the individual galaxies of our H-alpha imaging survey. A grand total of 74 galaxies have been studied, including the 9 galaxies of a recently studied sub-sample (Rossa & Dettmar 2000). 40.5% of all studied galaxies reveal extraplanar diffuse ionized gas, whereas in 59.5% of the survey galaxies no extraplanar diffuse ionized gas could be detected. The average distances of this extended emission above the galactic midplane range from 1-2 kpc, while individual filaments in a few galaxies reach distances of up to |z| ~ 6 kpc. In several cases a pervasive layer of ionized gas was detected, similar to the Reynolds layer in our Milky Way, while other galaxies reveal only extended emission locally. The morphology of the diffuse ionized gas is discussed for each galaxy and is compared with observations of other important ISM constituents in the context of the disk-halo connection, in those cases where published results were available. Furthermore, we present the distribution of extraplanar dust in these galaxies, based on an analysis of the unsharp-masked R-band images. The results are compared with the distribution of the diffuse ionized gas.

description: This study employs a choice experiment approach to investigate consumers’ preferences and WTP for organic food products. We use mixed logit models to examine preference heterogeneity. The results revealed significant heterogeneity in preferences for organic apples, milk, and beef product attributes among consumers. The willingness-to-pay (WTP) results obtained from mixed logit indicate gender-specific differences for the examined products of this study. Female respondents have a higher WTP for apple attributes, while higher WTP values for milk and beef attributes are observed for male respondents.

Out of nearly 700 (11th and 12th grade) applicants, 30 had been selected from all around Turkey. Students were introduced to the fundamentals of high energy physics and performed experiments that demonstrated the techniques of this field, such as a salad-bowl electrostatic accelerator, and a cloud chamber. Here we report on the planning, implementation and the outcomes of the school that can serve as a template for similar activities in the future.

title: Financial Conditions and the Money-Output Relationship in Canada
Creators: name: Kichian, Maral
Publisher: name: Bank of Canada
Year: 2012

description: We propose a drifting-coefficient model to empirically study the effect of money on output growth in Canada and to examine the role of prevailing financial conditions for that relationship. We show that such a time-varying approach can be a useful way of modelling the impact of money on growth, and can partly reconcile the lack of concensus in the literature on the question of whether money affects growth. In addition, we find that credit conditions also play a role in that relationship. In particular, there is an additional negative short-run impact of money on growth when credit is not readily available, supporting the precautionary motive for holding money. Finally, money is found to have no effect on output growth in the long-run.
description: Au moyen d’un modèle doté de coefficients pouvant varier au fil du temps, l’auteure étudie empiriquement l’effet de la monnaie sur la croissance de la production au Canada et examine le rôle des conditions financières dans cette relation. Elle montre que l’emploi de coefficients variables peut être utile pour modéliser l’incidence de la monnaie sur la croissance et contribuer à clarifier le débat en cours à ce sujet dans la littérature. L’auteure constate également que les conditions du crédit jouent un rôle dans la relation entre monnaie et croissance. Plus précisément, la monnaie a à court terme un effet négatif additionnel lorsque le financement n’est pas facilement accessible, les agents conservant alors des liquidités par mesure de précaution. À long terme, la monnaie s’avère sans influence sur la croissance de la production.
Ageing of annealed and chemically strengthened glass

Publisher: name: Challenging Glass Conference Proceedings
Year: 2020

description: Eight 45-year-old naturally aged windows collected from two buildings in two different locations revealed surface characteristic bending strengths in the range of 38-54 MPa. An artificial ageing method by sandfall was developed to reproduce the weakest failure stresses among the naturally aged samples. When this method was applied to chemically strengthened glass, the results varied depending on the glass composition and the strengthening cycle. To achieve the characteristic bending strength of 150 MPa specified by EN 12337, after the artificial ageing, soda-lime silicate glass needed routine strengthening cycle of 24 hours, whereas the newly developed Falcon® glass performed well after a shorter 8-hour strengthening cycle, with characteristic bending strength still above 300 MPa after artificial ageing. This study also includes a comparison with other studies in the literature regarding natural ageing and the application of sandfall artificial ageing to annealed glass and chemically strengthened glass.

description: The pattern speed in one of the fundamental parameters that determines the structure of barred galaxies. This quantity is usually derived from indirect methods or by employing model assumptions. The number of bar pattern speeds derived using the model independent Tremaine and Weinberg technique is still very limited. We present the results of model independent measurements of the bar pattern speed in four galaxies ranging in Hubble type from SB0 to SBbc. Three of the four galaxies in our sample are consistent with bars being fast rotators. The lack of slow bars is consistent with previous observations and suggests that barred galaxies do not have centrally concentrated dark matter halos. This contradicts simulations of cosmological structure formation and observations of the central mass concentration in nonbarred galaxies.

Publisher: name: Bank of Canada

description: Many studies have documented that daily realized volatility estimates based on intraday returns provide volatility forecasts that are superior to forecasts constructed from daily returns only. We investigate whether these forecasting improvements translate into economic value added. To do so we develop a new class of affine discrete-time option valuation models that use daily returns as well as realized volatility. We derive convenient closed-form option valuation formulas and we assess the option valuation properties using S&P500 return and option data. We find that realized volatility reduces the pricing errors of the benchmark model significantly across moneyness, maturity and volatility levels.
description: De nombreuses études ont montré que les estimations de la volatilité réalisée quotidienne qui se fondent sur les rendements intrajournaliers permettent d’aboutir à des prévisions de la volatilité plus justes que les projections faites uniquement à partir des rendements quotidiens. Les auteurs cherchent à déterminer si une telle amélioration prévisionnelle se traduit par une plus-value économique. À cette fin, ils construisent une nouvelle classe de modèles affines en temps discret d’évaluation des options qui font appel aux rendements quotidiens et également à la volatilité réalisée. Ils déduisent des formules analytiques des prix d’options et comparent, à l’aide de données sur les rendements et options liés à l’indice S&P500, les propriétés des modèles à l’étude. Ils constatent que la volatilité réalisée réduit de manière significative les erreurs d’évaluation du modèle de référence pour tous les degrés de parité, échéances et niveaux de volatilité examinés.

description: NASA's Kepler Mission promises to detect transiting Earth-sized planets in the habitable zones of solar-like stars. In addition, it will be poised to detect the reflected light component from close-in extrasolar giant planets (CEGPs) similar to 51 Peg b. Here we use the DIARAD/SOHO time series along with models for the reflected light signatures of CEGPs to evaluate Kepler's ability to detect such planets. We examine the detectability as a function of stellar brightness, stellar rotation period, planetary orbital inclination angle, and planetary orbital period, and then estimate the total number of CEGPs that Kepler will detect over its four year mission. The analysis shows that intrinsic stellar variability of solar-like stars is a major obstacle to detecting the reflected light from CEGPs. Monte Carlo trials are used to estimate the detection threshold required to limit the total number of expected false alarms to no more than one for a survey of 100,000 stellar light curves. Kepler will likely detect 100-760 51 Peg b-like planets by reflected light with orbital periods up to 7 days.

title: When Lower Risk Increases Profit: Competition and Control of a Central Counterparty
Creators: name: Fontaine, Jean-Sébastien

Publisher: name: Bank of Canada
Year: 2012

description: We model the behavior of dealers in Over-the-Counter (OTC) derivatives markets where a small number of dealers trade with a continuum of heterogeneous clients (hedgers). Imperfect competition and (endogenous) default induce a familiar trade-off between competition and risk. Increasing the number of dealers servicing the market decreases the price paid by hedgers but lowers revenue for dealers, increasing the probability of a default. Restricting entry maximizes welfare when dealers’ efficiency is high relative to their market power. A Central Counter-Party (CCP) offering novation tilts the trade-off toward more competition. Free-entry is optimal for all level of dealers’ efficiency if they can constrain risk-taking by its members. In this model, dealers can choose CCP rules to restrict entry and increase their benefits. Moreover, dealers impose binding risk constraints to increase revenues at the expense of the hedgers. In other words, dealers can use risk controls to commit to a lower degree of competition. These theoretical results provide one rationalization of ongoing efforts by regulators globally to promote fair and risk-based access to CCPs.
description: Les auteurs modélisent le comportement des courtiers sur des marchés de dérivés de gré à gré dans lesquels un petit nombre de courtiers traitent avec un éventail de clients hétérogènes. La concurrence imparfaite et le risque de défaut (endogène) donnent lieu à un arbitrage bien connu entre concurrence et risque. Si l’on accroît le nombre de courtiers desservant le marché, on observe une baisse des prix pour les clients, mais aussi une diminution des revenus des courtiers, ce qui augmente la probabilité d’une défaillance. Des restrictions à l’entrée optimisent le bien-être tant que l’efficience des courtiers est élevée relativement à leur pouvoir de marché. La présence d’une contrepartie centrale assurant la novation fait pencher la balance en faveur de la concurrence. La libre entrée offre une situation optimale quel que soit le niveau d’efficience des courtiers si la contrepartie centrale est en mesure de limiter les risques que prennent ses membres. Dans le modèle, les courtiers peuvent influer sur les règles qu’applique la contrepartie centrale de manière à restreindre l’entrée et à augmenter leurs avantages. De plus, ils peuvent imposer des mécanismes contraignants de limitation des risques afin de grossir leurs revenus aux dépens des clients. Autrement dit, les dispositifs de contrôle des risques permettent aux courtiers de s’engager à réduire la concurrence entre eux. Ces résultats théoriques fournissent une justification aux efforts déployés actuellement dans le monde par les autorités de réglementation pour favoriser un accès aux contreparties centrales qui soit équitable et fondé sur les risques.

Comparison of the Residual Stresses at the Edge and Surface of Thermally Toughened Glass
Creators: name: Lohr, Katharina

Publisher: name: Challenging Glass Conference Proceedings
Year: 2020

description: The strength of thermally toughened glass is regulated in EN 12150-1 for fully tempered glass (FTG) and EN 1863-1 for heat-strengthened glass (HSG). The manufacturer has to prove the strength by four-point bending tests based on EN 1288- 3. A measurement of the residual stresses of thermally toughened glass is not demanded. Consequently, the determination of the strength is containing the amount of residual stresses. As residual stress is depending on the manufacturing process, the amount and distribution can change within one glass pane and between different glass panes. A research project determined the residual stresses at the surfaces and the edges of HSG and FTG with varying glass thicknesses using photoelastic measurements. Thereby, FTG showed lower values of the residual stresses at the edge compared to the surface. Looking at HSG, the results of the residual stresses at the edge and surface were nearly the same. To analyse the edge strength, four-point bending tests were conducted. Thereby, the load was introduced into the strong axis of the specimens to implement constant tensile stresses along the glass edge. The comparison of the edge strengths showed that the edge strength of FTG is in the same range than HSG. Therefore, the lower residual stress at the edge of FTG reflects in significantly lower edge strengths. The paper includes a detailed presentation of the photoelastic measurements at the edge and the surface as well as the determined residual stresses of more than 80 specimens. In addition, the conducted four-point bending tests are described and the obtained edge strengths are correlated to the measured residual stresses. Based on that, the paper contains a discussion of the standardisations, the process of thermally prestressing and the consequences for the final glass strengths.

description: Previous studies emphasize that shocks can cause households to fall into poverty traps and to remain there because of risk aversion, yet to date there has been no attempt to discern whether shocks increase risk aversion over time in a developing country. We examine whether shocks increase risk aversion from the lean season to the harvest season among smallholder farmers in northwestern Vietnam. The risk preference elicitation techniques encompass a non-hypothetical lottery game and six hypothetical methods. Except for one assessment method, risk preferences are not stable. The influence of shocks on risk preference changes varies depending on the elicitation method. We find evidence that shocks for which the government provides far-reaching ex-post support – namely, drought and widespread livestock deaths – do not increase risk aversion, while shocks the government provides no such assistance for – namely, illness, death, flooding, or yield loss from pests – increase risk aversion. This indicates that government policies may be able to prevent individuals’ risk aversion from increasing over time from shocks.

description: We present numerical evidence that, in the planar limit, four dimensional Euclidean Yang-Mills theory undergoes a phase transition on a finite symmetrical four-torus when the length of the sides $l$ decreases to a critical value $l_c$. For $l>l_c$ continuum reduction holds so that at leading order in $N$, there are no finite size effects in Wilson and Polyakov loops. This produces the exciting possibility of solving numerically for the meson sector of planar QCD at a cost substantially smaller than that of quenched SU(3).

Year: 2012

description: This paper examines the role of bank credit in modeling and forecasting business cycle fluctuations, and investigates the international transmission of US credit shocks, using a global vector autoregressive (GVAR) framework and associated country-specific error correction models. The paper constructs and compiles a dataset on bank credit for 33 advanced and emerging market economies from 1979Q1 to 2009Q4. The empirical results suggest that the incorporation of credit provides significant improvement in modeling and forecasting output growth, changes in inflation and long run interest rates, for countries with developed banking sector. Impulse response analysis provide strong evidence of the international spillover of US credit shocks to the UK, the Euro area, Japan and other industrialized economies, and the propagation to the real economy.

À l’aide d’un modèle mondial de type GVAR (pour Global Vector Autoregressive) dans lequel chaque économie est décrite par un modèle à correction d’erreurs qui lui est propre, elle étudie la transmission aux autres pays des chocs de crédit provenant des États-Unis. L’auteure construit un ensemble de données sur le crédit bancaire pour 33 économies avancées et émergentes sur la période allant du premier trimestre de 1979 au quatrième trimestre de 2009. D’après les résultats empiriques, la prise en compte du crédit renforce sensiblement la modélisation et la prévision de la croissance de la production tout comme celles des variations de l’inflation et des taux d’intérêt à long terme dans le cas des pays ayant un secteur bancaire développé. L’analyse des fonctions de réponse fait clairement ressortir que les chocs américains de crédit se répercutent sur le Royaume-Uni, les pays de la zone euro, le Japon et les autres économies industrialisées et qu’ils se propagent à l’économie réelle.
Construction of Full Residual Stress Depth Profile in Glass Using the Knowledge of Surface Stress
Creators: name: Achintha, Mithila
Publisher: name: Challenging Glass Conference Proceedings
Year: 2020

description: This paper presents the development of a simple method to determine the full residual stress depth profile in architectural (i.e. construction sector) glass. The proposed model requires only the knowledge of the surface residual stress of glass, which can be known from the glass manufacturer or can be measured using a Scattered-Light-Polariscope (SCALP), as input. The requirement of through-thickness force equilibrium and the knowledge of parabolic shape of the residual stress depth profile are used to uniquely determine the residual stress depth profile in any given glass panel. Unlike the complex models reported in the literature, the proposed technique does not require modelling the complex multi-physics phenomenon of the generation of residual stress or the use of complex computational models. The residual stress predictions from the proposed model were validated against experimental results. The paper also presents a sensitivity analysis in order to justify the accuracy of the proposed model even after the possible errors/inaccuracies in the only input data (i.e. surface stress) of the model was incorporated in the analyses.

description: The classical problem of agricultural productivity measurement has regained interest due to recent price hikes in world food markets. At the same time, there is a new methodological debate on the appropriate identification strategies for addressing endogeneity and collinearity problems in production function estimation. We examine the plausibility of alternative identification strategies for the case of agriculture and test two related, innovative estimators using farm-level panel datasets from seven EU countries. The control function and dynamic panel approaches provide attractive conceptual improvements over the received ‘within’ and duality models. Even so, empirical implementation of the conceptual sophistications built in these estimators does not always live up to expectations. This is particularly true for the dynamic panel estimator, which mostly failed to identify reasonable elasticities for the (quasi-) fixed factors. Less demanding proxy approaches represent an interesting alternative for agricultural applications. In our EU sample, we find very low shadow prices for labour, land and fixed capital across countries.The production elasticity of materials is high, so that improving the availability of working capital is the most promising way to increase agricultural productivity.

title: Forecasting Inflation and the Inflation Risk Premiums Using Nominal Yields
Creators: name: Feunou, Bruno
name: Fontaine, Jean-Sébastien
Publisher: name: Bank of Canada
Year: 2012

description: We provide a decomposition of nominal yields into real yields, expectations of future inflation and inflation risk premiums when real bonds or inflation swaps are unavailable or unreliable due to their relative illiquidity. We combine nominal yields with surveys of inflation forecasts within a no-arbitrage model where conditional expectations are latent but spanned by the history of the observed data, analog to a GARCH model for the conditional variance. The filtering problem is numerically trivial and we conduct a battery of out-of-sample comparisons. Our favored model matches the quarterly inflation forecasts from surveys and uses the information in yields to produce the best monthly forecasts. Moreover, we restrict the distribution of the inflation Sharpe ratios to achieve economically reasonable estimates of the inflation risk premium and of the real rates. We find that the inflation risk premium (i) is positive on average, (ii) rises when the unemployment rate increases and (iii) when the level of interest rates decreases. Hence, real yields are more pro-cyclical than nominal yields due to variations of the inflation risk premiums.
description: Les auteurs proposent de décomposer les taux de rendement nominaux en trois éléments – taux réels, inflation anticipée et primes de risque d’inflation – lorsqu’il n’existe pas d’obligations ou de swaps indexés sur l’inflation ou que les données ne sont pas fiables en raison de l’illiquidité relative de ces instruments. Ils combinent les prévisions d’inflation recueillies par enquête aux rendements nominaux dans le cadre d’un modèle fondé sur l’absence d’arbitrage où les anticipations conditionnelles sont latentes mais dépendent des observations passées, à la manière de la variance conditionnelle dans un modèle GARCH. Le problème de filtrage est simple numériquement, ce qui permet aux auteurs de comparer entre elles un grand nombre de prévisions hors échantillon. Leur modèle parvient à reproduire les prévisions d’inflation trimestrielles tirées d’enquêtes, et c’est aussi celui qui fournit les meilleures prévisions mensuelles grâce à l’information extraite des taux nominaux. Les auteurs imposent en outre des restrictions à la distribution des ratios de Sharpe associés au risque d’inflation pour obtenir des estimations économiquement raisonnables de la prime de risque d’inflation et des taux réels. Ils constatent que la prime est positive en moyenne et qu’elle s’accroît quand le taux de chômage monte ou que les taux d’intérêt baissent. La procyclicité des rendements réels serait ainsi plus marquée que celle des rendements nominaux à cause de la variation des primes de risque d’inflation.

description: An international initiative to increase the use of central clearing for OTC derivatives emerged as one of the reactions to the 2008 financial crisis. The move to central clearing is a fundamental change in the structure of the market. Central clearing will help control counterparty credit risk, but it also has potential implications for market liquidity. We analyze the relationship between liquidity and central clearing using information on credit default swap clearing at ICE Trust and ICE Clear Europe. We find that the central counterparty chooses the most liquid contracts for central clearing, consistent with liquidity characteristics being important in determining the safety and efficiency of clearing. We further find that the introduction of central clearing is associated with a slight increase in the liquidity of a contract. This is consistent with two countervailing effects. On one hand, central clearing will likely increase collateral requirements relative to the pre-reform bilaterally-cleared market, thereby increasing clearing costs and possibly reducing the liquidity of the market. On the other hand, improved management of counterparty credit risk, increased transparency and operational efficiencies at central counterparties could bring more competition into OTC derivative markets and serve to increase liquidity.
description: Une initiative internationale visant à accroître le recours à la compensation centralisée des contrats de dérivés de gré à gré a été lancée en réponse à la crise financière de 2008. L’adoption de cette pratique constitue un changement fondamental de la structure du marché. La compensation centralisée aidera à limiter le risque de contrepartie, mais elle pourrait également se répercuter sur la liquidité du marché. Les auteurs analysent la relation entre liquidité et compensation centralisée à l’aide de données relatives à la compensation des swaps sur défaillance par ICE Trust et ICE Clear Europe. Ils constatent que la contrepartie centrale choisit d’effectuer la compensation des contrats les plus liquides, ce qui corrobore le rôle déterminant de cette caractéristique pour la sûreté et l’efficience de la compensation. Les auteurs notent aussi que la compensation s’accompagne d’une légère hausse de la liquidité des contrats. Ce résultat est compatible avec la présence de deux effets de sens opposé. D’un côté, la compensation centralisée pourrait accroître les exigences de garantie par rapport à celles en vigueur avant la réforme – lorsque les contrats étaient compensés bilatéralement –, d’où une augmentation des coûts de la compensation et une baisse possible de la liquidité. En revanche, la meilleure gestion du risque de contrepartie, le renforcement de la transparence et les gains d’efficience opérationnelle réalisés par les contreparties centrales pourraient stimuler la concurrence sur les marchés des dérivés de gré à gré et entraîner, de ce fait, une amélioration de la liquidité.

description: We consider a generalized version of the Takagi function, which is one of the most famous example of nowhere differentiable continuous functions. We investigate a set of conditions to describe the rate of convergence of Takagi class functions from the probabilistic point of view: The law of large numbers, the central limit theorem, and the law of iterated logarithm. On the other hand, we show that the Takagi function itself does not satisfy the law of large numbers in the usual sense.

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.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: Whenever a quantum system undergoes a cycle governed by a slow change of parameters, it acquires a phase factor: the geometric phase. Its most common formulations are known as the Aharonov-Bohm, Pancharatnam and Berry phases, but both prior and later manifestations exist. Though traditionally attributed to the foundations of quantum mechanics, the geometric phase has been generalized and became increasingly influential in many areas from condensed-matter physics and optics to high energy and particle physics and from fluid mechanics to gravity and cosmology. Interestingly, the geometric phase also offers unique opportunities for quantum information and computation. In this Review we first introduce the Aharonov-Bohm effect as an important realization of the geometric phase. Then we discuss in detail the broader meaning, consequences and realizations of the geometric phase emphasizing the most important mathematical methods and experimental techniques used in the study of geometric phase, in particular those related to recent works in optics and condensed-matter physics.

description: We study a supremacy distribution in evolving Barabasi-Albert networks. The supremacy $s_i$ of a node $i$ is defined as a total number of all nodes that are younger than $i$ and can be connected to it by a directed path. For a network with a characteristic parameter $m=1,2,3,...$ the supremacy of an individual node increases with the network age as $t^{(1+m)/2}$ in an appropriate scaling region. It follows that there is a relation $s(k) \sim k^{m+1}$ between a node degree $k$ and its supremacy $s$ and the supremacy distribution $P(s)$ scales as $s^{-1-2/(1+m)}$. Analytic calculations basing on a continuum theory of supremacy evolution and on a corresponding rate equation have been confirmed by numerical simulations.

description: In this work, a combined Voronoi and finite-discrete element method (FDEM) approach for reconstructing the post-fracture model of laminated glass (LG) was proposed. The fracture morphology was determined via introducing Voronoi tessellation with statistical distribution parameters such as the fragment face numbers, volume and sphericity. The residual interaction between glass fragments was described with cohesive zone model. One fractured LG block under uniaxial tension, which was taken from a triple layered LG beam with ionoplast interlayers, was modelled and validated with experimentally recorded data. Through iteration analysis, the key cohesive parameters were determined for the most applicable model. It is followed by investigating the influence due to the fragments interaction property. The results show that the cohesion and frictional property can be combined to well describe the residual interaction behaviour between fragments. The frictional property has a remarkable effect on the post-fracture resistance whereas the associated effect on the stiffness is not evident. Compared to other cohesive parameters, the cohesive stiffness factors present predominant effect on both the post-fracture stiffness and resistance.

Consumers’ Evaluation of Biotechnology in Food Products: New Evidence from a Meta-Survey

description: Other than previous meta-analyses, we ignore the reported main outcome of a study. Instead, we focus on studies that present descriptive statistics of survey statements as long as these address consumers’ evaluation of biotechnology in food products and capture responses on a numerical scale (e.g. Likert). To make these scales comparable across studies, a set of judges performed a randomized and repeated re-scaling of reported scale endpoints to a common benchmark scale. This approach allows to combine information from 1673 survey questions out of 214 different studies, covering 58 different countries and responses from more than 200 000 respondents. Findings from our mixed effects meta-model show that survey questions with positive (negative) connotations about biotechnology tend to be associated with positive (negative) measures of evaluation. After controlling for this, the European Union and many of its individual member countries appear insignificant. Evaluation of biotechnology is largely insensitive to the type of food product. Stated benefits of biotechnologies in food do not produce any significant positive reaction, except medical features build into food. Instead, price discounts, increased production and various perceived risks generate significant negative coefficients. Joint research projects between academic departments and industry consortia report more positive measures of consumer evaluation than any other type of publication.
