description: Structure of exact solutions modelling confinement is discussed for SU(3)-Yang-Mills equations and uniqueness of such confining solutions is proved in a certain sense. Relationship of the obtained results to QCD and the confinement mechanism is considered. Incidentally the Wilson confinement criterion for the found solutions is verified and also numerical estimates for strength of magnetic colour field responsible for linear confinement are adduced in the ground state of charmonium.

description: Recent claims of the Seattle group of evidence of "slope difference between CD [Coulomb Dissociation] and direct [capture] results" are based on wrong and selective data. When the RIKEN2 data are included correctly, and previously published Direct Capture (DC) data are also included, we observe only a 1.9 sigma difference in the extracted so called "scale independent slope (b)", considerably smaller than claimed by the Seattle group. The very parameterization used by the Seattle group to extract the so called b-slope parameter has no physical foundation. Considering the physical slope (S' = dS/dE), we observe a 1.0 sigma agreement between slopes (S') measured in CD and DC, refuting the need for new theoretical investigation. The claim that S17(0) values extracted from CD data are approximately 10% lower than DC results, is based on misunderstanding of the CD method. Considering all of the published CD S17(0) results, with adding back an unconfirmed E2 correction of the MSU data, yields very consistent S17(0) results that agree with recent DC measurements of the Seattle and Weizmann groups. The recent correction of the b-slope parameter (0.25 1/MeV) suggested by Esbensen, Bertsch and Snover was applied to the wrong b-slope parameter calculated by the Seattle group. When considering the correct slope of the RIKEN2 data, this correction in fact leads to a very small b-slope parameter (0.14 1/MeV), less than half the central value observed for DC data, refuting the need to correct the RIKEN2 data. In particular it confirms that the E2 contribution in the RIKEN2 data is negligible. The dispersion of measured S17(0) is mostly due to disagreement among individual DC experiments and not due to either experimental or theoretical aspects of CD.

description: The objective of this article is to estimate the derived demand for imported fresh cheese products into Japan when fresh cheese import data are disaggregated by source country of production. We provide empirical measures of the sensitivity of demand to changes in total imports, own-price, and cross-prices among exporting countries for fresh cheese. Japan's derived demand for U.S. fresh cheese products is perfectly inelastic. Thus, the import demand competition among importing countries should be based upon differences in product characteristics.
A magneto-optic investigation of flux penetration in high temperature superconductors
Creators: name: Gardner, Michael W.
Publisher: name: University of British Columbia
Year: 2009

description: An efficient non-destructive magneto-optic imaging system was developed that employs special iron-garnet indicator films to image magnetic fields in high temperature superconductors. The flexibility of the system allows the investigation of many different types of samples having different sizes and characteristics. Two very high quality, low pinning, thin, flat YBa₂Cu₃O₆.₉₅ single crystals are imaged using this system to observe field penetration dynamics. Slightly different pinning characteristics of both samples enable a comparison to be made between the different flux penetration dynamics observed. In one ultra low pinning crystal, penetrating flux is found to accumulate in the sample's central regions while avoiding the inner edges and in the other higher pinning crystal flux tends to initially avoid both the central regions and sample's inner edges. These results compare favourably with a theoretical model of Zeldov et al.[21] that characterizes penetration phenomenon in low pinning superconductors. Field penetration of a Tl₂Ba₂CaCu₂ thin film is also observed for different sample temperatures up to the sample's superconducting transition temperature. A new computational technique is employed to calculate the critical current of the film using imaged field strengths. A comparison of the imaged fields and calculated currents is made with a theoretical model devised to characterize field penetration in superconductors having a thin circular geometry. From these results the critical current temperature dependence is established and is fitted to a simple phenomenon logical model. A small discontinuity in the data 10 K below the sample's transition temperature is also noted and is examined.

description: It is well established that the product of the volume coefficient of thermal expansion and the bulk modulus is nearly constant at temperatures higher than the Debye temperature. Using this approximation allows predicting the values of the bulk modulus. The derived analytical solution for the temperature dependence of the isothermal bulk modulus has been applied to ten substances. The good correlations to the experiments indicate that the expression may be useful for substances for which bulk modulus data are lacking.

description: We study a nonperturbative single field (inflaton) governed cosmological model from a 5D Noncompact Kaluza-Klein (NKK) theory of gravity. The inflaton field fluctuations are estimated for different epochs of the evolution of the universe. We conclude that the inflaton field has been sliding down its (quadratic) potential hill along all the evolution of the universe and a mass of the order of the Hubble parameter. In the model here developed the only free parameter is the Hubble parameter, which could be reconstructed in future from Super Nova Acceleration Probe (SNAP) data.

description: Let $S=(G, σ)$ be a signed graph where $G=(V, E)$ is a graph called the underlying graph of $S$ and $σ:E(G) \rightarrow \{+,~-\}$. Let $f:V(G) \rightarrow \{1,2,\dots,|V(G)|\}$ such that $σ(uv)=+$ if and only if $f(u)$ and $f(v)$ are of same parity and $σ(uv)=-$ if and only if $f(u)$ and $f(v)$ are of opposite parity. Under $f$ we get a signed graph $G_f$ denoted as $S$, which is a parity signed graph. In this paper, we initiate the study of parity labeling in signed graphs and we define and find `rna' number denoted as $σ^-(S)$ for some classes of signed graphs. We also characterize some signed graphs which are parity signed graphs. Some directions for further research are also suggested.

description: Continued value creation is paramount for the survival of firms competing in today's high velocity global business environment. This paper presents a conceptual framework for understanding how firms can create and capture value within a highly volatile and uncertain business environment by exploiting both performance gaps and opportunity gaps through the development and use of flexible supply chain architectures. The choice of flexible organizational architecture allows for the continued reconfiguration of the independent modular components of the supply chain so as to achieve optimal leverage of both the firms core competencies as well as their collaborative partners complementary resources. The case of "Cellars of Canterbury", a New Zealand based International wine marketing and distribution cooperative enterprise provides empirical support.

description: We review the present status of the QCD corrected cross sections and kinematic distributions for the production of a Higgs boson in association with bottom quarks at the Fermilab Tevatron and CERN Large Hadron Collider. Results are presented for the Minimal Supersymmetric Standard Model where, for large tan beta, these production modes can be greatly enhanced compared to the Standard Model case. The next-to-leading order QCD results are much less sensitive to the renormalization and factorization scales than the lowest order results, but have a significant dependence on the choice of the renormalization scheme for the bottom quark Yukawa coupling. We also investigate the uncertainties coming from the Parton Distribution Functions and find that these uncertainties can be comparable to the uncertainties from the remaining scale dependence of the next-to-leading order results. We present results separately for the different final states depending on the number of bottom quarks identified.

The Quantum Governor: Automatic quantum control and reduction of the influence of noise without measuring

description: The problem of automatically protecting a quantum system against noise in a closed circuit is analyzed. A general scheme is developed built from two steps. At first, a distillation step is induced in which undesired components are removed to another degree of freedom of the system. Later a recovering step is employed which the system gains back its initial density. An Optimal-Control method is used to generate the distilling operator. The scheme is demonstrated by a simulation of a two level byte influenced by white noise. Undesired deviations from the target were shown to be reduced by at least two orders of magnitude on average. The relations between the quantum version of the classical Watt's Governor and the field of quantum information are also discussed.
A study of the b-delayed particle decay of 9C
Creators: name: Gete, Ermias A.
Publisher: name: University of British Columbia
Year: 2009

description: The β-decay of ⁹C (ti/2=126.5 ms) to the particle-unstable nucleus ⁹B has been studied at the TISOL facility at TRIUMF with an intent to measure the μ-decay scheme and to study the structure of ⁹B . A l l of the states in ⁹B populated by the β⁺ decay of ⁹C are unbound and decay ultimately into 2α+p. It is therefore necessary to measure the decay particles in coincidence in order to measure the excitation energy of ⁹B . Two coincidence experiments with different detector geometries were performed. In the first experiment, four ΔE - E particle telescopes arranged in face-to-face pairs measured singles and double coincidence particle spectra. For the second experiment, a pair of position sensitive Double-Sided Silicon Strip Detectors were used in conjunction with particle telescopes to record three-fold coincidence events. The coincidence measurements allowed us to kinematically identify events from ⁵L i +α and ⁸Be+p, the two major decay modes of the states of ⁹B . Several states in ⁹B have been observed and β-branching ratios to these states, and a and proton decay branches from these states have been measured. Because most of the ⁹B levels are broad, the state shapes fed by the β decay of ⁹C are distorted by the β-decay phase-space factor. In order to describe the states of ⁹B , and the secondary compound states such as ⁵Li into which the ⁹B states decay, a simplified one-level .R-matrix description of these states was used, and the spectra from both decay modes were fitted. β-decay branching ratios as well as Gamow-Teller strengths for the observed states of ⁹B were extracted from these fits. Four strongly populated states of ⁹B have been observed; the ground state (47±5) % and excited states at 2.34 (35±7) %, 2.8 (6.7±0.7) % and 12.16 (6.8±0.7)% MeV. The strong branch to the 12.16 M eV state corresponds to a large Gamow-Teller matrix element with BGT=2.5±0.25.

description: Dissimilar notions of quantum correlations have been established, each being motivated through particular applications in quantum information science and each competing for being recognized as the most relevant measure of quantumness. In this contribution, we experimentally realize a form of quantum correlation that exists even in the absence of entanglement and discord. We certify the presence of such quantum correlations via negativities in the regularized two-mode Glauber-Sudarshan function. Our data show compatibility with an incoherent mixture of orthonormal photon-number states, ruling out quantum coherence and other kinds of quantum resources. By construction, the quantumness of our state is robust against dephasing, thus requiring fewer experimental resources to ensure stability. In addition, we theoretically show how multimode entanglement can be activated based on the generated, nonentangled state. Therefore, we implement a robust kind of nonclassical photon-photon correlated state with useful applications in quantum information processing.
Modelling butterfly wing eyespot patterns

description: Eyespots are concentric motifs with contrasting colours on butterfly wings. Eyespots have intra- and inter-specific visual signalling functions with adaptive and selective roles. We propose a reaction-diffusion model that accounts for eyespot development. The model considers two diffusive morphogens and three non-diffusive pigment precursors. The first morphogen is produced in the focus and determines the differentiation of the first eyespot ring. A second morphogen is then produced, modifying the chromatic properties of the wing background pigment precursor, inducing the differentiation of a second ring. The model simulates the general structural organisation of eyespots, their phenotypic plasticity and seasonal variability, and predicts effects from microsurgical manipulations on pupal wings as reported in the literature.

A Representation of Real and Complex Numbers in Quantum Theory

description: A quantum theoretic representation of real and complex numbers is described here as equivalence classes of Cauchy sequences of quantum states of finite strings of qubits. There are 4 types of qubits each with associated single qubit annihilation creation (a-c) operators that give the state and location of each qubit type on a 2 dimensional integer lattice. The string states, defined as finite products of creation operators acting on the qubit vacuum state correspond to complex rational numbers with real and imaginary components. These states span a Fock space. Arithmetic relations and operations are defined for the string states. Cauchy sequences of these states are defined, and the arithmetic relations and operations lifted to apply to these sequences. Based on these, equivalence classes of these sequences are seen to have the requisite properties of real and complex numbers. The representations have some interesting aspects. Quantum equivalence classes are larger than their corresponding classical classes, but no new classes are created. There exist Cauchy sequences such that each state in the sequence is an entangled superposition of the real and imaginary components, yet the sequence is a real number. Also, except for coefficients of superposition states, the construction is done with no reference to the real and complex number base, R and C, of the Fock space.

description: We combine Creutz energy conservation with Kawasaki spin exchange to simulate the microcanonical dynamics of a system of interacting particles. Relaxation occurs via Glauber spin-flip activation using a self-consistent temperature. Heterogeneity in the dynamics comes from finite-size constraints on the spin exchange that yield a distribution of correlated regions. The simulation produces a high-frequency response that can be identified with the boson peak, and a lower-frequency peak that contains non-Debye relaxation and non-Arrhenius activation, similar to the primary response of supercooled liquids.

description: The debate over the safety of genetically modified organisms (GMO's) has varied greatly in intensity. In Europe, the debate has been vigorous and European consumers have, in general, been extremely skeptical of the technology and unwilling to assume the risks associated with GMOs. Many retailers in Europe have promised that they will not sell food products that contain GMOs. In the U.S., consumer reaction to GMOs has been more muted. While some surveys have shown that a majority of Americans support the use of biotechnology, others have found that many Americans have reservations about the technology. Most of the research published to date has focused on consumer opinions regarding GMOs. Relatively little research has focused on understanding the basis of consumer opinion or developing or evaluating strategies targeted at gaining consumer acceptance of GMO products. The purpose of this research is to evaluate the effect of two potential strategies to gain consumer acceptance of GMO foods. Specifically, we examine the effectiveness of using a familiar brand or federal government certification on consumer acceptance of GMOs. This research is timely because the rapid pace of GMO development and adoption will soon make it difficult, if not impossible, to maintain separate products based on the presence or absence of GMO content. The conceptual basis for the model used in this paper is Lancaster's theory of consumer demand. The paper discusses the results of the analysis that was undertaken.

Subjects: Industrial Organization

description: The concept of knowledge and its related dimensions of information and learning have traditionally received considerable research attention by scholars of organization and strategic management theorists. The increasing role of knowledge as defining characteristic of the modern knowledge economy has renewed an interest to the importance of knowledge to a firm's competitive advantage. Such interest has raised a significant conceptual issue as to whether the new knowledge economy warrants an alternative framework to understanding competitive strategy. As a result, a conceptual model of knowledge based competitive advantage is proposed. Such a conceptual framework rests upon the subjective tenets of Austrian entrepreneurship and strategic network perspectives. Based on this conceptual framework, the central argument of this research is founded on the subjective behaviors of the alert entrepreneur where: knowledge based competitive advantage rests upon the management of strategic networks of strong and weak information ties so as to capitalize diverse knowledge experiences in creating and exploiting the complementary relations of a changing knowledge economy. The contribution of this research is it provides a departure from the static perspectives of Resource-based view and Industrial Organizational economic perspectives in accommodating for evolutionary changes of network knowledge. Implicit in this perspective is that sustainable competitive performance is not a realizable outcome. Rather knowledge based competitive performance is transitory in which the extent of such performance is contingent on the management of evolving network relations.

description: The galaxy number density is a key quantity to compare theoretical predictions to the observational data from current and future Large Scale Structure surveys. The precision demanded by these Stage IV surveys requires the use of second order cosmological perturbation theory. Based on the independent calculation published previously, we present the result of the comparison with the results of three other groups at leading order. Overall we find that the differences between the different approaches lie mostly on the definition of certain quantities, where the ambiguity of signs results in the addition of extra terms at second order in perturbation theory.

description: Using the full potential linearised augmented planewave method we study the electronic and magnetic properties of the (001) and (111) surfaces of the half-metallic Heusler alloy NiMnSb from first-principles. We take into account all possible surface terminations including relaxations of these surfaces. Special attention is paid to the spin-polarization at the Fermi level which governs the spin-injection from such a metal into a semiconductor. In general, these surfaces lose the half-metallic character of the bulk NiMnSb, but for the (111) surfaces this loss is more pronounced. Although structural optimization does not change these features qualitatively, specifically for the (111) surfaces relaxations can compensate much of the spin-polarization at the Fermi surface that has been lost upon formation of the surface.

description: In this study, we address three important challenges related to disease transmissions such as the COVID-19 pandemic, namely, (a) providing an early warning to likely exposed individuals, (b) identifying individuals who are asymptomatic, and (c) prescription of optimal testing when testing capacity is limited. First, we present a dynamic-graph based SEIR epidemiological model in order to describe the dynamics of the disease propagation. Our model considers a dynamic network that accounts for the interactions between individuals over time, such as the ones obtained by manual or automated contact tracing, and uses a diffusion-reaction mechanism to describe the state dynamics. This dynamic graph model helps identify likely exposed/infected individuals to whom we can provide early warnings, even before they display any symptoms and/or are asymptomatic. Moreover, when the testing capacity is limited compared to the population size, reliable estimation of individual's health state and disease transmissibility using epidemiological models is extremely challenging. Thus, estimation of state uncertainty is paramount for both eminent risk assessment, as well as for closing the tracing-testing loop by optimal testing prescription. Therefore, we propose the use of arbitrary Polynomial Chaos Expansion, a popular technique used for uncertainty quantification, to represent the states, and quantify the uncertainties in the dynamic model. This design enables us to assign uncertainty of the state of each individual, and consequently optimize the testing as to reduce the overall uncertainty given a constrained testing budget. These tools can also be used to optimize vaccine distribution to curb the disease spread when limited vaccines are available. We present a few simulation results that illustrate the performance of the proposed framework, and estimate the impact of incomplete contact tracing data.

 Type species: Coccodus lindstroemi Davis, 1890 (here designated).   Diagnosis
 Gladiopycnodontid with an elongate prefrontal forming a short rostrum outpacing the lower jaw level. Anterior extremity of the prefrontal acuminate and spiny. Vomer bearing small rounded molariform teeth irregularly ranged. Orbitosphenoid, pleurosphenoid and basisphenoid present. Supratemporal sutured to the rear of the skull. Premaxilla long, broad, toothless and sutured by its upper margin to the prefrontal. Dentary bearing 2 incisiform teeth. Hypertrophied trapezoid preopercle covering the cheek. Large first infraorbital (only known in Joinvillichthys kriweti gen. et sp. nov.). Exposed part of the hyomandibula-dermohyomandibula much smaller than the preopercle. Long nuchal horn with a spiny posterior margin and articulated only on the dermosupraoccipital. Pectoral girdle closely associated to the skull, forming a cephalo-thorax. Cleithrum hypertrophied, with a gigantic posterior ventral process. Hypercleithrum hypertrophied. Well developed posttemporal, with an acuminate posterior extremity. 16 to 17 neural spines, all fused to the neural arches, before the epichordal series. 10 haemal spines before the hypochordal series (only known in Joinvillichthys lindstroemi). Short dorsal fin with 8 or 9 rays. Short anal fin with 7 to 9 rays. 7 to 9 spiny scutes in the dorsal ridge. 3 or 4 scutes in the ventral keel, the last scute or the two last ones associated to the postcoelomic bone. Body completely covered by small, flake-like scales in the abdominal region and by large, scute-like scales in the caudal region.   Etymology
 The generic name is chosen in memory of Lord Jean de Joinville (1224–1317), seneschal of Champagne, who related in his biography of Louis IX the presentation of some Lebanese fossil fishes to this French king at Saïda during the seventh crusade (Gayet et al. 2012: 8). The Greek word ichthys, fish, is added.

Maximum correntropy criterion for robust TOA-based localization in NLOS environments

description: We investigate the problem of time-of-arrival (TOA) based localization under possible non-line-of-sight (NLOS) propagation conditions. To robustify the squared-range-based location estimator, we follow the maximum correntropy criterion, essentially the Welsch $M$-estimator with a redescending influence function which behaves like $\ell_0$-minimization towards the grossly biased measurements, to derive the formulation. The half-quadratic technique is then applied to settle the resulting optimization problem in an alternating maximization (AM) manner. By construction, the major computational challenge at each AM iteration boils down to handling an easily solvable generalized trust region subproblem. It is worth noting that the implementation of our localization method requires nothing but merely the TOA-based range measurements and sensor positions as prior information. Simulation and experimental results demonstrate the competence of the presented scheme in outperforming several state-of-the-art approaches in terms of positioning accuracy, especially in scenarios where the percentage of NLOS paths is not large enough.

description: Let $p:\mathbb{C}\to\mathbb{R}$ be a subharmonic, nonharmonic polynomial and $τ$ a real parameter. Define $\bar{Z}_{τp} = \partial_{\bar z} + τp_{\bar z}$, a closed, densely-defined operator on $L^2(\mathbb{C})$. If $\Box_{τp} = \bar{Z}_{τp}\bar{Z}_{τp}^*$ and $τ>0$, we solve the heat equation $ (\partial_s + \Box_{τp}) u =0$, $u(0,z) = f(z)$, on $(0,\infty)\times\mathbb{C}$. The solution comes via the heat semigroup $e^{-s\Box_{τp}}$, and we show that $u(s,z)$ is given as integration of the intial condition against a distributional kernel $H_{τp}(s,z,w)$. We prove that $H_{τp}$ is $C^\infty$ off the diagonal $\{(s,z,w):s=0 \text{and }z=w\}$ and that $H_{τp}$ and its derivatives have exponential decay.

description: We give bounds on the Poincare (inverse spectral gap) constant of a non-negative, integer-valued random variable W, under negative dependence assumptions such as ultra log-concavity and total negative dependence. We show that the bounds obtained compare well to others in the literature. Examples treated include some occupancy and urn models, a random graph model and small spacings on the circumference of a circle. Applications to Poisson convergence theorems are considered.

description: Over the past several decades, thousands of planets have been discovered outside of our Solar System. These planets exhibit enormous diversity, and their large numbers provide a statistical opportunity to place our Solar System within the broader context of planetary structure, atmospheres, architectures, formation, and evolution. Meanwhile, the field of exoplanetary science is rapidly forging onward towards a goal of atmospheric characterization, inferring surface conditions and interiors, and assessing the potential for habitability. However, the interpretation of exoplanet data requires the development and validation of exoplanet models that depend on in-situ data that, in the foreseeable future, are only obtainable from our Solar System. Thus, planetary and exoplanetary science would both greatly benefit from a symbiotic relationship with a two-way flow of information. Here, we describe the critical lessons and outstanding questions from planetary science, the study of which are essential for addressing fundamental aspects for a variety of exoplanetary topics. We outline these lessons and questions for the major categories of Solar System bodies, including the terrestrial planets, the giant planets, moons, and minor bodies. We provide a discussion of how many of these planetary science issues may be translated into exoplanet observables that will yield critical insight into current and future exoplanet discoveries.

description: We carry out a thorough study of weight-shifting operators on Hilbert modular forms in characteristic $p$, generalizing the author's prior work with Sasaki to the case where $p$ is ramified in the totally real field $F$. In particular we use the partial Hasse invariants and Kodaira-Spencer filtrations defined by Reduzzi and Xiao to improve on Andreatta and Goren's construction of partial $Θ$-operators, obtaining ones whose effect on weights is optimal from the point of view of geometric Serre weight conjectures. Furthermore we describe the kernels of partial $Θ$-operators in terms of images of geometrically constructed partial Frobenius operators. Finally we apply our results to prove a partial positivity result for minimal weights of mod $p$ Hilbert modular forms.

description: We study front propagation in the reversible reaction-diffusion system A + A A on a 1-d lattice. Extending the idea of leading particle in studying the motion of the front we write a master equation in the stochastically moving frame attached to this particle. This approach provides a systematic way to improve on estimates of front speed obtained earlier. We also find that the leading particle performs a correlated random walk and this correlation needs to be taken into account to get correct value of the front diffusion coefficient.

description: Several types of simultaneous approximation term (SAT) for diffusion problems discretized with diagonal-norm multidimensional summation-by-parts (SBP) operators are analyzed based on a common framework. Conditions under which the SBP-SAT discretizations are consistent, conservative, adjoint consistent, and energy stable are presented. For SATs leading to primal and adjoint consistent discretizations, the error in output functionals is shown to be of order $h^{2p}$ when a degree $p$ multidimensional SBP operator is used to discretize the spatial derivatives. SAT penalty coefficients corresponding to various discontinuous Galerkin fluxes developed for elliptic partial differential equations are identified. We demonstrate that the original method of Bassi and Rebay, the modified method of Bassi and Rebay, and the symmetric interior penalty method are equivalent when implemented with SBP diagonal-E operators that have diagonal norm matrix, e.g., the Legendre-Gauss-Lobatto SBP operator in one space dimension. Similarly, the local discontinuous Galerkin and the compact discontinuous Galerkin schemes are equivalent for this family of operators. The analysis remains valid on curvilinear grids if a degree $\le p+1$ bijective polynomial mapping from the reference to physical elements is used. Numerical experiments with the two-dimensional Poisson problem support the theoretical results.
