WHAT CAN TURKEY GAIN FROM FULL AGRICULTURAL MARKET INTEGRATION WITH THE EU WITHOUT BEING A MEMBER?
Creators: name: Grethe, Harald
name: Grethe, Harald
Publisher: name: Unknown
Year: 2004
Subjects: International Relations/Trade

description: Turkey established a customs union (CU) with the EU in 1996, which excludes agricultural products. This article analyses the effects of an inclusion of agriculture in the CU as well as alternative policy options on the Turkish agricultural sector. To this aim, a comparative-static, partial equilibrium model of the Turkish agricultural sector is developed. The complete liberalisation of the agricultural sector leads to significant comparative static welfare gains of about ~670 million compared to the continuation of current policies. For most products an inclusion of agriculture in the CU leads to similar results as the complete liberalisation of agricultural trade.
Valence-bond-solid order in antiferromagnets with spin-lattice coupling

description: We propose that a valence-bond-solid (VBS) order can be stabilized in certain two-dimensional antiferromagnets due to spin-lattice coupling. In contrast to the VBS state of the Affleck-Kennedy-Lieb-Tesaki (AKLT) type in which the spin $2S$ and the lattice coordination $z$ must be commensurate, the spin-lattice coupling-induced VBS state can occur when $2S$ is not an integer multiple of $z$. As a concrete example, S=2 spins on the triangular network with $z=6$ is discussed. Within the Schwinger boson mean-field theory it is shown that the ground state is given by the $\sqrt{3}\times\sqrt{3}$ modulation of the valence bond amplitudes for sufficiently strong spin-lattice coupling. Using the corresponding AKLT wave function, we work out the excitation spectrum for this state within the single-mode approximation. The calculated spectrum should provide a new type of collective mode which is distinct from the spin wave excitations of the magnetically ordered ground state.

REMARQUES
Le genre Leptotelopus pourrait être le type d’une tribu séparée en raison de ses caractères très particuliers: pattes ambulatoires du mâle extraordinairement allongées dans la partie postérieure du corps; présence d’un organe stridulatoire au doigt mobile du télopode mâle.
Le retour des Prionobelini parmi les Sphaeropoeini ne donne pas au genre Prionobelum un statut définitif basé sur une diagnose solide, pas plus qu’aux autres taxons de rang générique de cette tribu, qui ont tous grand besoin d’être révisés, car ils se distinguent mal les uns des autres, sur des caractères dont la fiabilité n’est pas évidente.

description: This paper delves into the debate on the proliferation of regional trade arrangements by focusing on bilateral agricultural trade data over the 1962-1995 period for countries that currently are members of NAFTA, Mercosur, the EU and APEC. Agricultural is chosen because it has historically been protected by developed and dis-protected by developing nations, while in the case of the EU, its Common Agricultural Policy was the major policy jointly managed and funded by member countries. We suggest that the literature has tended to focus on factors explaining the level of trade, and neglected factors affecting growth in trade. While neighborhood characteristics affect neighborhood trade, they also appear to affect the policy regimes of neighboring countries. The shift to more outward oriented regimes is thus likely to induce a dynamic in trade among neighboring countries requiring several years to stabilize. As neighborhood trade grows, it is natural to form trade arrangements so as to harmonize policies and to remove other barriers. If this is the case, then we should expect the growth in intra regional trade to exceed growth in extra-regional trade, and these patterns should occur before the formation of regional trade arrangements. Our results support this explanation.

We develop a diagrammatic technique in which the leading order contributions are given by tree diagrams. We introduce a Wigner transform for multipoint correlators and derive the evolution equations for three- and four-point Wigner functions for the problem of nonlinear stochastic diffusion with multiplicative noise.

D e s c r i p t i o n. Winged fruit elongate-elliptical, with a central seed body; wing with pointed apex and base; fruit 25.1–32.12 mm long, 7.3–8.6 mm wide; seed body 4.9–6.4 mm long, 3.7–5.3 mm wide; ventral (intramarginal) vein of the wing prominent, marginal or submarginal; stylar vein present, minor vein small, mostly parallel, occasionally dichotomizing or anastomosing (more on dorsal side); seed bodies sub-circular.
 R e m a r k s. Ailanthus fruits in North America have traditionally been placed into either Ailanthus americana COCKERELL or Ailanthus lesquereuxi COCKERELL but are morphologically identical to those described earlier as Ailanthus confucii UNGER (Corbett and Manchester 2004). The fossil matches the description of A. confucci by having a marginal to submarginal ventral vein as opposed to having an inset vein as in Ailanthus tardensis HABLY (Corbett and Manchester 2004). A. confucii is recognized from the early Eocene through late Miocene of western North America (Corbett and Manchester 2004). Among extant species, it resembles the temperate eastern Asian native species, Ailanthus altissima, which is invasive today in North America and Europe.

These values are used to constrain the Cabibbo-Kobayashi-Maskawa phase phi_2; the solution consistent with the Standard Model is phi_2 = (88 +-17) degrees or 59 deg.< phi_2 < 115 deg. at 90% CL.

Multi-Objective Bayesian Optimization for Accelerator Tuning

description: Particle accelerators require constant tuning during operation to meet beam quality, total charge and particle energy requirements for use in a wide variety of physics, chemistry and biology experiments. Maximizing the performance of an accelerator facility often necessitates multi-objective optimization, where operators must balance trade-offs between multiple objectives simultaneously, often using limited, temporally expensive beam observations. Usually, accelerator optimization problems are solved offline, prior to actual operation, with advanced beamline simulations and parallelized optimization methods (NSGA-II, Swarm Optimization). Unfortunately, it is not feasible to use these methods for online multi-objective optimization, since beam measurements can only be done in a serial fashion, and these optimization methods require a large number of measurements to converge to a useful solution.Here, we introduce a multi-objective Bayesian optimization scheme, which finds the full Pareto front of an accelerator optimization problem efficiently in a serialized manner and is thus a critical step towards practical online multi-objective optimization in accelerators.This method uses a set of Gaussian process surrogate models, along with a multi-objective acquisition function, which reduces the number of observations needed to converge by at least an order of magnitude over current methods.We demonstrate how this method can be modified to specifically solve optimization challenges posed by the tuning of accelerators.This includes the addition of optimization constraints, objective preferences and costs related to changing accelerator parameters.
Wave and particle properties can be spatially separated in a quantum entity

description: Wave and particle are two fundamental properties of Nature. The wave-particle duality has indicated that a quantum object may exhibit the behaviours of both wave and particle, depending upon the circumstances of the experiment. The major significance of wave-particle duality has led to a fundamental equation in quantum mechanics, the Schr{\" o}dinger equation. At present, the principle of wave-particle duality has been deeply rooted in people's hearts. This gives rise to a common sense perception that wave property and particle property coexist simultaneously in a quantum entity, and these two physical attributes cannot be completely separated from each other. In classical physics, a similar common sense is that a physical system is inseparable from its physical properties. However, this has been recently challenged and beaten by a quantum phenomenon called the "quantum Cheshire cat", for which a cat and its grin can be separated spatially. In this work, we propose a thought experiment based on the similar technology of quantum Cheshire cat. We find that wave and particle attributes of a quantum entity can be completely separated, thus successfully dismantling the wave-particle duality for a quantum entity. Our result is still consistent with the complementarity principle and deepens the understanding of quantum foundations.

Modelling of the thermal evolution of steel strips cooled in the hot rolling runout table
Creators: name: Hernandez-Avila, Victor Hugo
Publisher: name: University of British Columbia
Year: 2009

description: The controlled cooling of steel on the runout table has become a standard practice in the production of flat hot-rolled products, and since its introduction by BISRA in 1957, has been adopted because it is a vital tool in meeting the increasing demand of steels with better quality and higher mechanical properties. Although approximately one third of the total steel produced in the world is cooled using laminar cooling in the runout table with some degree of success, little is known about what actually happens during cooling. Even though many of the runout table operations are relatively under control, it is still not known how far these operations are from the optimum. Whereas the influence of steel chemistry has been traditionally exploited to accomplish certain mechanical properties, the recently recognized effect of cooling on mechanical properties has been exploited poorly. This increases the importance of the study of the runout table cooling. The runout table process has been studied in detail during this work, and important observations leading to a better understanding of this operation were obtained. A mathematical model for the runout table cooling was developed, which solves the transient 1-D heat transfer in a steel strip moving through the cooling units in the runout table. The model takes into account the individual fluid flow characteristics of each jet such as its velocity, diameter, temperature, and the geometry of the nozzle arrays, and relates them to other process variables, such as strip speed, chemistry, and thickness, to predict the thermal evolution of the steel. The model was validated by comparing the predictions of the model for the processing of two plain carbon steels, A36 and DQSK, with measurements in ten different runout table operations. Very good agreement with measurements was obtained. The boundary conditions were obtained by the mathematical modelling of the boiling curves during water jet cooling based on the application of the macrolayer evaporation mechanism, which lead to accurate predictions of the boiling curves, which compare very well with most of the reported measurements in the literature.

description: This paper introduces a new market analysis methodology based on maximum likelihood estimation of a mixture distribution model incorporating price, transfer cost, and trade flow data. Not only does this method obviate statistical problems associated with conventional price analysis methods, it also permits differentiation between market integration and competitive market equilibrium. The model generates estimates of the frequency of alternative regimes, combinations of which provide useful, intuitive measures of intermarket tradability, competitive market equilibrium, perfect integration, segmented equilibrium, and segmented disequilibrium. An application to trade in soybean meal among Pacific Rim economies demonstrates the usefulness of the method.

description: This paper provides an overview of the demographics of the South African population based on the October Household Survey (OHS) and the Income and Expenditure Survey (IES), both conducted by Statistics South Africa in 1995. Figures and tables are used throughout to paint a picture of the structure of the South African population, both at household level (IES data) and individual level (OHS data). Specific reference is made to the racial and spatial composition of households and individuals, the age distribution of the population, household sizes and their structures, as well as educational attainment of individuals. A section is also devoted to labour market issues such as unemployment and occupations/skills of workers. The paper serves as a reference framework and aims to assist in defining policy questions.

description: A Social Accounting Matrix (SAM) is a comprehensive, economy-wide database that contains information about the flow of resources associated with all transactions that have taken place between economic agents in an economy during a given period of time. Its use can extend beyond that of serving as a summary of transactions that have taken place in an economy. The SAM approach to modelling makes use of the SAM format to present economic theory. The versatility of SAMs has made them databases of preference for economic modelling. This paper provides an overview of the structure of a SAM, touching on issues such as economic accounting, the circular flow of resources in the economy and the SAM-accounts, and thereafter explains the SAM approach to modelling. As such the paper serves as a reference framework for users of SAMs.

description: Perturbative contributions to single-beam two-photon transition rates may be divided into two types. The first, involving low-energy intermediate states, require a high-order perturbation treatment, or an exact diagonalization. The other, involving high energy intermediate states, only require a low-order perturbation treatment. We show how to partition the effective transition operator into two terms, corresponding to these two types, in such a way that a many-body perturbation expansion may be generated that obeys the linked cluster theorem and has a simple diagrammatic representation.

description: Biology is both an important application area and a source of motivation for development of advanced machine learning techniques. Although much attention has been paid to large and complex data sets resulting from high-throughput sequencing, advances in high-quality video recording technology have begun to generate similarly rich data sets requiring sophisticated techniques from both computer vision and time-series analysis. Moreover, just as studying gene expression patterns in one organism can reveal general principles that apply to other organisms, the study of complex social interactions in an experimentally tractable model system, such as a laboratory ant colony, can provide general principles about the dynamics of other social groups. Here, we focus on one such example from the study of reproductive regulation in small laboratory colonies of more than 50 Harpegnathos ants. These ants can be artificially induced to begin a ~20 day process of hierarchy reformation. Although the conclusion of this process is conspicuous to a human observer, it remains unclear which behaviors during the transient period are contributing to the process. To address this issue, we explore the potential application of One-class Classification (OC) to the detection of abnormal states in ant colonies for which behavioral data is only available for the normal societal conditions during training. Specifically, we build upon the Deep Support Vector Data Description (DSVDD) and introduce the Inner-Outlier Generator (IO-GEN) that synthesizes fake "inner outlier" observations during training that are near the center of the DSVDD data description. We show that IO-GEN increases the reliability of the final OC classifier relative to other DSVDD baselines. This method can be used to screen video frames for which additional human observation is needed.

Subjects: Research Methods/ Statistical Methods

description: This paper serves as an overview of various multivariate statistical techniques that can be used to analyse and describe survey datasets. Such analyses are useful for gaining a better understanding of results and the interpretation thereof. In particular this paper evaluates some of the standard statistical techniques that can be used to analyse consumption patterns of households, both in terms of expenditure on individual goods or baskets of goods. The ultimate aim is to determine whether these techniques - e.g. multivariate tests of significance and cluster analysis techniques - can be successfully employed to assist in forming representative household groups in terms of expenditure patterns. As such this paper is exploratory and does not aim to obtain final results. It is envisaged that more comprehensive research will be done at a later stage of the project. Initial findings suggest that there is merit in using multivariate statistical techniques to form representative household groups, although certain constraints and problems may be encountered.
Excited state Rényi entropy and subsystem distance in two-dimensional non-compact bosonic theory. Part II. Multi-particle states

description: We study the excited state Rényi entropy and subsystem Schatten distance in the two-dimensional free massless non-compact bosonic field theory, which is a conformal field theory. The discretization of the free non-compact bosonic theory gives the harmonic chain with local couplings. We consider the field theory excited states that correspond to the harmonic chain states with excitations of more than one quasiparticle, which we call multi-particle states. This extends the previous work by the same authors to more general excited states. In the field theory we obtain the exact Rényi entropy and subsystem Schatten distance for several low-lying states. We also obtain the short interval expansion of the Rényi entropy and subsystem Schatten distance for general excited states. In the locally coupled harmonic chain we calculate numerically the excited state Rényi entropy and subsystem Schatten distance using the wave function method. We find excellent matches of the analytical results in the field theory and numerical results in the gapless limit of the harmonic chain. We also make some preliminary investigations of the Rényi entropy and the subsystem Schatten distance in the extremely gapped limit of the harmonic chain.

Super-Chern-Simons spectra from Exceptional Field Theory
Creators: name: Varela, Oscar
Publisher: name: arXiv
Year: 2020
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: Exceptional Field Theory has been recently shown to be very powerful to compute Kaluza-Klein spectra. Using these techniques, the mass matrix of Kaluza-Klein vector perturbations about a specific class of AdS$_4$ solutions of $D=11$ and massive type IIA supergravity is determined. These results are then employed to characterise the complete supersymmetric spectrum about some notable ${\cal N}=2$ and ${\cal N}=3$ AdS$_4$ solutions in this class, which are dual to specific three-dimensional superconformal Chern-Simons field theories.

Orbital migration and the period distribution of exoplanets
Creators: name: Del Popolo, A.
Publisher: name: arXiv
Year: 2005
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We use the model for the migration of planets introduced in Del Popolo, Yesilyurt & Ercan (2003) to calculate the observed mass and semimajor axis distribution of extra-solar planets. The assumption that the surface density in planetesimals is proportional to that of gas is relaxed, and in order to describe disc evolution we use a method which, using a series of simplifying assumptions, is able to simultaneously follow the evolution of gas and solid particles for up to $10^7 {\rm yr}$. The distribution of planetesimals obtained after $10^7 {\rm yr}$ is used to study the migration rate of a giant planet through the model of this paper. The disk and migration models are used to calculate the distribution of planets as function of mass and semimajor axis. The results show that the model can give a reasonable prediction of planets' semi-major axes and mass distribution. In particular there is a pile-up of planets at $a \simeq 0.05$ AU, a minimum near 0.3 AU, indicating a paucity of planets at that distance, and a rise for semi-major axes larger than 0.3 AU, out to 3 AU. The semi-major axis distribution shows that the more massive planets (typically, masses larger than $4 M_{\rm J}$) form preferentially in the outer regions and do not migrate much. Intermediate-mass objects migrate more easily whatever the distance they form, and that the lighter planets (masses from sub-Saturnian to Jovian) migrate easily.

description: This paper forms part of a series of papers that present profiles of South Africa's provinces, with a specific focus on key demographic statistics, poverty and inequality estimates, and estimates of unemployment. In this volume comparative statistics are presented for agricultural and non-agricultural households, as well as households from different racial groups, locations (metropolitan, urban and rural areas) and district municipalities of the North West. Most of the data presented are drawn from the Income and Expenditure Survey of 2000 and the Labour Force Survey of September 2000, while some comparative populations statistics are extracted from the National Census of 2001 (Statistics South Africa). The papers should be regarded as general guidelines to (agricultural) policymakers as to the current socio-economic situation in the North West, particularly with regards to poverty, inequality and unemployment.
The outburst of a 60 min AM CVn reveals peculiar color evolution: implications for outbursts in long period double white dwarfs

description: We report on multi-wavelength observations during quiescence and of the first detected outburst of the ~60 min orbital period AM CVn SDSS J113732+405458. Using X-ray and UV observations we determined an upper limit duration of the event of about one year. The amplitude of the outburst was remarkably small, of around one magnitude in r and 0.5 magnitudes in g. We have also investigated the color variations of SDSS J113732+405458 and other long period AM CVns in outbursts and identified a track on the color-magnitude diagram that is not compatible with the predictions of the disk instability model, suggesting that some outbursts in long period AM CVns are caused by enhanced mass-transfer. To our knowledge, these are the first studies of the color evolution in AM CVns. During quiescence we measured an X-ray luminosity for SDSS J113732+405458 of ~3E29 erg/s in the 0.5-10 keV band. This indicates a very low accretion rate, in agreement with the disk instability model for long period systems. However, such a model predicts stable disks at somewhat long periods. The discovery of this system outburst, along with similarities to the long period system SDSS J080710+485259 with a comparably long, weak outburst, indicates that these enhanced mass-transfer events may be more common in long period AM CVns. A larger sample would be needed to determine empirically at what period, if any, the disk instability stops functioning entirely. Finally, we identified an infrared excess in the quiescence spectrum attributable to the donor. This makes SDSS J113732+405458 the second AM CVn to have a directly detected donor.

description: We consider the problem of the detection of brain hemorrhages from three dimensional (3D) electrical impedance tomography (EIT) measurements. This is a condition requiring urgent treatment for which EIT might provide a portable and quick diagnosis. We employ two neural network architectures -- a fully connected and a convolutional one -- for the classification of hemorrhagic and ischemic strokes. The networks are trained on a dataset with $40\,000$ samples of synthetic electrode measurements generated with the complete electrode model on realistic heads with a 3-layer structure. We consider changes in head anatomy and layers, electrode position, measurement noise and conductivity values. We then test the networks on several datasets of unseen EIT data, with more complex stroke modeling (different shapes and volumes), higher levels of noise and different amounts of electrode misplacement. On most test datasets we achieve $\geq 90\%$ average accuracy with fully connected neural networks, while the convolutional ones display an average accuracy $\geq 80\%$. Despite the use of simple neural network architectures, the results obtained are very promising and motivate the applications of EIT-based classification methods on real phantoms and ultimately on human patients.

Effective Actions for the SU(2) Confinement-Deconfinement Phase Transition

description: We compare different Polyakov loop actions yielding effective descriptions of finite-temperature SU(2) Yang-Mills theory on the lattice. The actions are motivated by a simultaneous strong-coupling and character expansion obeying center symmetry and include both Ising and Ginzburg-Landau type models. To keep things simple we limit ourselves to nearest-neighbor interactions. Some truncations involving the most relevant characters are studied within a novel mean-field approximation. Using inverse Monte-Carlo techniques based on exact geometrical Schwinger-Dyson equations we determine the effective couplings of the Polyakov loop actions. Monte-Carlo simulations of these actions reveal that the mean-field analysis is a fairly good guide to the physics involved. Our Polyakov loop actions reproduce standard Yang-Mills observables well up to limitations due to the nearest-neighbor approximation.
