description: Using a fact that the effective conductivity sigma_{e} of 2D random heterophase systems in the orthogonal magnetic field is transformed under some subgroup of the linear fractional group, connected with a group of linear transformations of two conserved currents, the exact values for sigma_{e} of isotropic heterophase systems are found. As known, for binary (N=2) systems a determination of exact values of both conductivities (diagonal sigma_{ed} and transverse Hall sigma_{et}) is possible only at equal phase concentrations and arbitrary values of partial conductivities. For heterophase (N > 2) systems this method gives exact values of effective conductivities, when their partial conductivities belong to some hypersurfaces in the space of these partial conductivities and the phase concentrations are pairwise equal. In all these cases sigma_e does not depend on phase concentrations. The complete, 3-parametric, explicit transformation, connecting sigma_e in binary systems with a magnetic field and without it, is constructed

description: We present the results of a next-to-leading order analysis of single top production including the decay of the top quark. Radiative effects are included both in the production and decay stages, using a general subtraction method. This calculation gives a good treatment of the jet activity associated with single top production. We perform an analysis of the single top search at the Tevatron, including a consideration of the main backgrounds, many of which are also calculated at next-to-leading order.

description: We address a three-dimensional model capable of describing coupled damage and plastic effects in solids at finite strains. Formulated within the variational setting of {\it generalized standard materials}, the constitutive model results from the balance of conservative and dissipative forces. Material response is rate-independent and associative and damage evolution is unidirectional. We assess the model features and performance on both uniaxial and non-proportional biaxial tests. The constitutive model is then complemented with the quasistatic equilibrium system and initial and boundary conditions. We produce numerical simulations with the help of the powerful multiphysics finite element software NETGEN/NGSolve. We show the flexibility of the implementation and run simulations for various 2D and 3D settings under different choices of boundary conditions and possibly in presence of pre-damaged regions.

description: We present a class of observables which are suitable for determining the fidelity of a state to the multipartite Greenberger-Horne-Zeilinger (GHZ) state. Given an expectation value of an observable belonging to the class, we give a simple formula that gives a lower bound and an upper bound for the fidelity. Applying the formula to the GHZ-state preparation experiment by Pan {\it et al}. {[Nature (London) {\bf 403}, 515 (2000)]}, we show that the observed state lies outside of the class of biseparable mixed three-qubit states. We also show that for this class of operators, adopting the principle of minimum variance {[Phys. Rev. A {\bf 60}, 4338 (1999)]} in the state estimation always results in the state with the minimum fidelity.

On the structure of parasitic gravity-capillary waves in the small surface tension limit

description: In this paper, we examine the formation of small capillary waves (parasitic ripples) on the surface of steep steadily-travelling gravity waves. Previously, authors have developed ad-hoc analytical procedures for describing the formation of such parasitic ripples in potential flows; however, it has not been clear whether the small-surface tension limit is well-posed -- that is, whether it is possible for an appropriate travelling gravity-capillary wave to be continuously deformed to the classic Stokes wave in the limit of vanishing surface tension. The work of Chen & Saffman (1980) had suggested smooth continuation was not possible. In this paper, we numerically explore the low surface tension limit of the steep gravity-capillary travelling-wave problem. Our results allow for a classification of the bifurcation structure that arises, and serve to unify a number of previous numerical studies. Crucially, we demonstrate that different choices of solution amplitude can lead to subtle restrictions on the continuation procedure; the use of wave energy as an amplitude condition allows solution branches to be continuously deformed to the zero surface tension limit.

description: This article extends the Berry, Levinsohn, Pakes (1995) model to include retail services by Boston supermarkets in an equilibrium model of breakfast cereals and then tests alternative vertical pricing games between manufacturers and supermarkets to ascertain who’s got the pricing power. Empirical results show that retail services play a significant role in market equilibrium. Consumers are willing to pay for additional retail services embedded in their cereal purchases, especially those with higher income and no kids. Markups and market shares increase with the level of retail services, although manufacturers dominate pricing decisions in the market channel for breakfast cereals. Significant downward biases in price elasticities and markup estimates result when services are ignored.

The bid data are collected from 353 randomly recruited undergraduate students participated in Wuhan, China, during the spring and early summer of 2008.The experiment auction suggest most participant hold a positive WTA for GM rice cookie, which suggest that consumers regard GM rice an inferior substitutes for non-GM rice. Information favorable of GM rice will decrease the WTA, while negative information will increase the WTA. When information of both sides is revealed, the WTA bids decrease at different pace according to the sequence of discovering information.

description: Fermi-edge singularity changes in a dramatic way in a nonequilibrium system, acquiring features which reflect the structure of energy distribution. In particular, it splits into several components if the energy distribution exhibits multiple steps. While conventional approaches, such as bosonization, fail to describe the nonequilibrium problem, an exact solution for a generic energy distribution can be obtained with the help of the method of functional determinants. In the case of a split Fermi distribution, while the `open loop' contribution to Green's function has power law singularities, the tunneling density of states profile exhibits broadened peaks centered at Fermi sub-levels.

description: The Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS) has continued to be fiercely debated between North and South, particularly with respect to its provisions for the agricultural sector. Article 27.3(b) of the TRIPS Agreement requires WTO member countries to offer some form of intellectual property protection for new plant varieties, either in the form of patents (common in the U.S.) or plant breeder’s rights (PBR). This paper analyses the effects of the introduction of PBRs in almost 70 importing countries on the value of exports of agricultural seeds and planting material from 10 exporting EU countries, including all principal traditional exporters of seeds, as well as the US. A fixed effects quantile regression model, based on the general specification for the gravity model for international trade, is estimated using panel data covering 19 years (1989-2007) of export flows in order to assess the effect of International Convention on the Protection of New Varieties of Plants (UPOV) membership on seed imports. Basing inference on the panel bootstrap, we find no significant effect from UPOV membership on seed imports.

description: An all-sky catalog of 18020 disc-like galaxies is presented. The galaxies are selected from the Extended Source Catalog of the Two Micron All-Sky Survey (XSC 2MASS) basing on their 2MASS axial ratio a/b >= 3. The Catalog contains data on magnitudes of a galaxy in the J, H, K_s bands, its axial ratio, positional angle, index of luminosity concentration, as well as identification of the galaxy with the LEDA and the NED databases. Unlike the available optical catalogs, the new 2MFGC catalog seems to be more suitable to study cosmic streaming on a scale of z <= 0.1. The dipole moment of distribution of the bright (K < 11 mag) 2MFGC objects (l = 227 degr, b = 41 degr or SGL = 90 degr, SGB = -43 degr) lies within statistical errors (+/- 15 degr) in the direction of the IRAS dipole and the optical RFGC dipole.

The aim is to offer a description in terms of generators and relations. A conjecture in this respect is offered with the centralizers presented as quotients of the Askey-Wilson algebra. Support for the conjecture is provided by an examination of the representations of the quotients. The conjecture is also shown to be true in a number of cases thereby exhibiting in particular the Temperley-Lieb, Birman-Murakami-Wenzl and one-boundary Temperley-Lieb algebras as quotients of the Askey-Wilson algebra.

description: As changes in modern agribusiness markets have placed increasing emphasis to the study of structural change processes, this research advances an agent based model to examine transitions from a spot market exchange to a vertically coordinated arrangement in a supply chain system. This agent base simulation model draws from the subjective theme of Austrian entrepreneurship, behavioral theories of the firm and social networks. The results of this agent based simulation model indicate that structural change occurs with market structures that facilitate information transmission rather than from incentive based contractual arrangements.

The boundary flow is terminated at a nontrivial infrared fixed point. We identify a form of whole boundary state corresponding to this fixed point.

description: A multi-feedstock approach is crucial for sustainable biofuel production in South Africa. In respect of ethanol production, biofuel producers should be allowed to draw on a range of starch-based crops including maize. A multi-feedstock approach will enable producers to select crops best suited to the agro-climate of the regions where their plants are situated and to minimize logistic costs by sourcing crops grown closest to their plants. In recent months, plans to use maize to produce ethanol have raised concerns that this could jeopardize food security in South Africa.

description: Throughout history people have been facing risks associated with food. Food scares of the twentieth century have caused consumer panic leading to loss of confidence in the safety of the food chain. Many public and private initiatives in the form of food quality certification schemes have evolved to restore confidence. One such private initiative is the GLOBALGAP (former EUREPGAP). This executive interview discusses the role of GLOBALGAP in food certification with Dr. Kristian Moeller who is the Managing Director for GLOBALGAP. This discussion took place during IAMA’s 17th Annual World Forum and Symposium in Parma, Italy on June 25, 2007.

description: We present a Chandra and XMM-Newton study of X-ray emission from the lobes of 33 classical double radio galaxies and quasars. We report new detections of lobe-related X-ray emission in 11 sources. Together with previous detections we find that X-ray emission is detected from at least one radio lobe in ~75 percent of the sample. For all of the lobe detections, we find that the measured X-ray flux can be attributed to inverse-Compton scattering of the cosmic microwave background radiation, with magnetic field strengths in the lobes between (0.3 - 1.3) B_eq, where the value B_eq corresponds to equipartition between the electrons and magnetic field assuming a filling factor of unity. There is a strong peak in the magnetic field strength distribution at B ~ 0.7 B_eq. We find that > 70 percent of the radio lobes are either at equipartition or electron dominated by a small factor. The distribution of measured magnetic field strengths differs for narrow-line and broad-line objects, in the sense that broad-line radio galaxies and quasars appear to be further from equipartition; however, this is likely to be due to a combination of projection effects and worse systematic uncertainty in the X-ray analysis for those objects. Our results suggest that the lobes of classical double radio sources do not contain an energetically dominant proton population, because this would require the magnetic field energy density to be similar to the electron energy density rather than the overall energy density in relativistic particles.

description: In this paper, we find some new exact solutions to the Einstein-Gauss-Bonnet equations. First, we prove a theorem which allows us to find a large family of solutions to the Einstein-Gauss-Bonnet gravity in $n$-dimensions. This family of solutions represents dynamic black holes and contains, as particular cases, not only the recently found Vaidya-Einstein-Gauss-Bonnet black hole, but also other physical solutions that we think are new, such as, the Gauss-Bonnet versions of the Bonnor-Vaidya(de Sitter/anti-de Sitter) solution, a global monopole and the Husain black holes. We also present a more general version of this theorem in which less restrictive conditions on the energy-momentum tensor are imposed. As an application of this theorem, we present the exact solution describing a black hole radiating a charged null fluid in a Born-Infeld nonlinear electrodynamics.

description: We report on the pressure evolution of the giant anomalous Hall effect (AHE) in the chiral antiferromagnet Mn$_3$Ge. The AHE originating from the non-vanishing Berry curvature in Mn$_3$Ge can be continuously tuned by application of hydrostatic pressure. At room temperature, the Hall signal changes sign as a function of pressure and vanishes completely at $p=1.53$ GPa. Even though the Hall conductivity changes sign upon increasing pressure, the room-temperature saturation value of 23 ${\rm Ω^{-1}cm^{-1}}$ at 2.85 GPa is remarkably high and comparable to the saturation value at ambient pressure of about 40 ${\rm Ω^{-1}cm^{-1}}$. The change in the Hall conductivity can be directly linked to a gradual change of the size of the in-plane components of the Mn moments in the non-collinear triangular magnetic structure. Our findings, therefore, provide a route for tuning of the AHE in the chiral antiferromagnetic Mn$_3$Ge.

description: High potato price volatility, decreasing demand for fresh potatoes and prices below the cost of production led to a decision of a number of Idaho potato growers to organize the United Fresh Potato Growers of Idaho, a marketing cooperative. The programs and strategies of the cooperative target both the production and marketing of fresh potatoes in Idaho. To evaluate the effectiveness of the programs implemented by the cooperative, we examine the level and volatility of fresh potato prices during two periods: before the cooperative was organized and when the cooperative is in the market. We find empirical evidence suggesting that fresh potato prices were higher and less volatile during the period when the cooperative was in the market.

description: This paper explores the importance of a producer’s market orientation on their subjective performance within agricultural commodity markets. Using a structural equation model of beef producers, our findings suggest that market oriented firms are highly innovative and achieve superior performance. These findings are consistent with previous research on the market orientation-performance relationship in heterogeneous product markets. The cost focus of a firm was also found to have a significant influence on innovation, but no direct effect on performance. This suggests that beef producers should follow a balanced approach utilizing both an external market and an internal productivity focus to achieve superior returns as opposed to solely focusing on internal productivity as many producers currently do.
Eigenstate Entanglement Entropy in Random Quadratic Hamiltonians

description: The eigenstate entanglement entropy has been recently shown to be a powerful tool to distinguish integrable from generic quantum-chaotic models. In integrable models, a unique feature of the average eigenstate entanglement entropy (over all Hamiltonian eigenstates) is that the volume-law coefficient depends on the subsystem fraction. Hence, it deviates from the maximal (subsystem fraction independent) value encountered in quantum-chaotic models. Using random matrix theory for quadratic Hamiltonians, we obtain a closed-form expression for the average eigenstate entanglement entropy as a function of the subsystem fraction. We test its correctness against numerical results for the quadratic Sachdev-Ye-Kitaev model. We also show that it describes the average entanglement entropy of eigenstates of the power-law random banded matrix model (in the delocalized regime), and that it is close but not the same as the result for quadratic models that exhibit localization in quasimomentum space.
Looking through ruin : Canadian photography at Ypres and the archive of war
Creators: name: Alexandre, David
Publisher: name: University of British Columbia
Year: 2009

description: This thesis examines the relationship between the photographic archive of the First World War and Canadian war memory through an analysis of the production of photographs depicting the ruins of Ypres, Belgium and their postwar appropriation. Taken by official photographers in the employment of the Canadian War Records Office, the photographs were intended to act as both historical documents and, paradoxically, as publicity and propaganda images. Both functions of the photographs work to construct a unified image of the war and are similarly characterized by a repressive structure. Ypres, almost entirely destroyed during the war, was both the site of Canada's first battle and major victory as well as a contentious site connoting military mismanagement and wasteful loss of life. Resultantly, representations of the city's ruins are suggestive of a corresponding shift from a mythic to a horrific war in First World War historiography that took place in the decades proceeding it. Images of Ypres' ruins were filtered through both material censorship enforced by the military to elicit high morale and psychic censorship. Photographers made mechanized war conform to their visual expectations. However, the repressive structure literally contains that which it represses as an uncanny double and invariably allows for the possibility of its return. I argue that the anodyne and conventionalized image generated by official photographs of ruins also contains and signifies the destructive violence of modern warfare. Finally, I examine the construction of these conflicting narratives as they develop around the simultaneous processes of archivization and circulation ever-widening circles of mnemonic constructs such as postcards and tourist brochures at the same time that they were being archived. I argue that rather than contaminating and damaging the archival meaning of the photographs, the archive is an accumulative institution capable of incorporating a variety of conflicting narratives without ruining its authority.

description: In this paper, we test the weak cosmic censorship conjecture (WCCC) in the nearly extremal static charged black holes of Lanczos-Lovelock-Maxwell gravity based on the new version of gedanken experiments proposed by Sorce and Wald. After introducing the null energy condition of the matter fields, we show that the (nearly) extremal black holes can be destroyed under the first-order approximation for the case with $S'(r_h)\leq 0$, where $S(r_h)$ is the entropy of the background black hole geometry in Lanczos-Lovelock gravity. It implies that the WCCC is violated in these situations. For the case with $S'(r_h)>0$, the nearly extremal black holes cannot be overcharged by the new version of the gedanken experiments for both first- and second-order approximations of perturbation. These results indicate that the WCCC is satisfied in the Lanczos-Lovelock gravity with the condition $S'(r_h)>0$. Our work also implies that the WCCC will play a natural role to constrain the Lanczos-Lovelock gravities. Finally, we also show that the destroy condition $S'(r_h)<0$ implies that the nearly extremal black hole is thermodynamically unstable under the first-order approximation.

description: Computer simulations of many physical phenomena rely on approximations by models with a finite number of unknowns. The number of these parameters determines the computational effort needed for the simulation. On the other hand, a larger number of unknowns can improve the precision of the simulation. The adaptive finite element method (AFEM) is an algorithm for optimizing the choice of parameters so accurate simulation results can be obtained with as little computational effort as possible.

The Tatlow Creek revitalization project
Creators: name: Milley, Susan Olucia
Publisher: name: University of British Columbia
Year: 2009

description: My project deals with one of the greatest resources on earth: water. Increasing populations and land development requires increased responsibility to preserve and enhance natural hydrologic processes as much as possible. But most often, current development and engineering practices do not recognize this growing responsibility, as urban water courses have been buried and / or culverted beneath the ground. Rainwater has been given an "out of sight out of mind" treatment as it is funneled into vast and expensive sewer system networks which leads to expensively and unnecessarily treated water, and destroys the natural recycling process of the hydrological system which recharges our water resources. One method of regenerating the hydrological system is by revealing, or 'daylighting' buried streams, and by implementing measures which will sustain them in their complex urban contexts. Streams within the Greater Vancouver area were once common. Now few streams remain in this urban landscape, and fewer yet are healthy enough to support their once-thriving fish habitats. Healthy streams and their environments create diverse habitats for animals and plants, create pathways for movement in the larger landscape, reduce flooding of larger water bodies and reduce the amount of water being unnecessarily treated with sewage. Furthermore, streams give character and identity to the landscape and foster in people a greater sense of ecological recognition, community pride, value, and stewardship. My research is based on my belief that by re-introducing streams back into our urban fabric and designing effective stormwater design strategies to sustain them, we can greatly enhance and benefit both the ecological environment as well as our city communities. My thesis presents a model for daylighting Tatlow Creek; an urban stream in the Greater Vancouver district of Kitsilano. This model strives to: 1) Daylight Tatlow creek North under Point Grey Road, through Volunteer Park and into English Bay 2) Naturalize the riparian area 3 ) Restore the creek's base flow by suggesting short and longterm strategies for infiltration throughout the Tatlow Watershed. Tatlow Creek presents a unique opportunity in which to propose a viable system of green infrastructure which thoroughly integrates an urban park with its medium-density urban context. This system designs for a strategically planned and managed network of green spaces and corridors interconnected with an existing urban environment, which supports native flora and fauna, sustains water resources and natural hydrological processes, and contributes to the health and quality of life of the community. The district of Kitsilano currently possesses many positive aspects of sustainable ecological design, and as such presents a favourable practicability for adapting and retrofitting these with a long term design strategy for its entire watershed. This would then eventually connect with an expanded green infrastructure network throughout the greater Vancouver region.

description: In a continuous-time framework we study the technology and investment choice problem of a continuous co-digestion biogas plant dealing with randomly fluctuating relative convenience of input factor costs. Input factors enter into the productive process together mixed according to a given initial rule. Being inputs relative convenience stochastically evolving, a successive revision of the initial rule may be desirable. Hence, when the venture starts the manager may or may not install a flexible technology allowing for such option. Investment is irreversible and flexibility is costly. The problem is solved determining in the light of future prospects the optimal revision and then playing backward fixing the investment timing rule.

description: This is the 5-th paper in the series devoted to explicit formulating of the rules needed to manage an effective field theory of strong interactions in S-matrix sector. We discuss the principles of constructing the meaningful perturbation series and formulate two basic ones: uniformity and summability. Relying on these principles one obtains the bootstrap conditions which restrict the allowed values of the physical (observable) parameters appearing in the extended perturbation scheme built for a given localizable effective theory. The renormalization prescriptions needed to fix the finite parts of counterterms in such a scheme can be divided into two subsets: minimal -- needed to fix the S-matrix, and non-minimal -- for eventual calculation of Green functions; in this paper we consider only the minimal one. In particular, it is shown that in theories with the amplitudes which asymptotic behavior is governed by known Regge intercepts, the system of independent renormalization conditions only contains those fixing the counterterm vertices with $n \leq 3$ lines, while other prescriptions are determined by self-consistency requirements. Moreover, the prescriptions for $n \leq 3$ cannot be taken arbitrary: an infinite number of bootstrap conditions should be respected. The concept of localizability, introduced and explained in this article, is closely connected with the notion of resonance in the framework of perturbative QFT. We discuss this point and, finally, compare the corner stones of our approach with the philosophy known as ``analytic S-matrix''.

description: We examine the dynamics of a bright solitary wave in the presence of a repulsive or attractive localized ``impurity'' in Bose-Einstein condensates (BECs). We study the generation and stability of a pair of steady states in the vicinity of the impurity as the impurity strength is varied. These two new steady states, one stable and one unstable, disappear through a saddle-node bifurcation as the strength of the impurity is decreased. The dynamics of the soliton is also examined in all the cases (including cases where the soliton is offset from one of the relevant fixed points). The numerical results are corroborated by theoretical calculations which are in very good agreement with the numerical findings.

description: As the role played by statistical and computational sciences in climate and environmental modelling and prediction becomes more important, Machine Learning researchers are becoming more aware of the relevance of their work to help tackle the climate crisis. Indeed, being universal nonlinear function approximation tools, Machine Learning algorithms are efficient in analysing and modelling spatially and temporally variable environmental data. While Deep Learning models have proved to be able to capture spatial, temporal, and spatio-temporal dependencies through their automatic feature representation learning, the problem of the interpolation of continuous spatio-temporal fields measured on a set of irregular points in space is still under-investigated. To fill this gap, we introduce here a framework for spatio-temporal prediction of climate and environmental data using deep learning. Specifically, we show how spatio-temporal processes can be decomposed in terms of a sum of products of temporally referenced basis functions, and of stochastic spatial coefficients which can be spatially modelled and mapped on a regular grid, allowing the reconstruction of the complete spatio-temporal signal. Applications on two case studies based on simulated and real-world data will show the effectiveness of the proposed framework in modelling coherent spatio-temporal fields.
