description: At present, agricultural cooperatives, like all cooperatives, are faced with many challenges. They are questioned about their organizational and management framework, their relations with local communities and with the market. In Italy, there is an ongoing debate relating to how cooperatives at large should or are supposed to evolve in a context in which the market pressure seems to overcome the traditional characteristics of the cooperative movement (mutuality, solidarity, the "one head one vote" principle, and so on). How to adequately balance the innovation thrust and the cooperative principles? How can agricultural cooperatives develop in the face of the 'ever overwhelming market forces? Is the legal framework provided for cooperatives still competitive? By taking into account the long-rooted experience of agricultural cooperatives in the County of Trento, the authors intend to analyze the main economic, organizational and legal problems affecting these cooperatives, On examining these problems, the article also intends to bring about some proposals and recommendations for the future developments of agricultural cooperatives.

description: As shown recently (O.B.Isaeva et al., Phys.Rev E64, 055201), the phenomena intrinsic to dynamics of complex analytic maps under appropriate conditions may occur in physical systems. We study scaling regularities associated with the effect of additive noise upon the period-tripling bifurcation cascade generalizing the renormalization group approach of Crutchfield et al. (Phys.Rev.Lett., 46, 933) and Shraiman et al. (Phys.Rev.Lett., 46, 935), originally developed for the period doubling transition to chaos in the presence of noise. The universal constant determining the rescaling rule for the intensity of the noise in period-tripling is found to be $γ=12.2066409...$ Numerical evidence of the expected scaling is demonstrated.

description: In this paper we will explore the 2D system describing trapped ionic system in the quadrapole field with a superposition of rationally symmetric hexapole and octopole fields for meromorphic integrability. We use the Lyapunov's and Ziglin-Morales-Ruiz-Ramis's classical methods for the proofs. The monodromy group of the normal variational equation (NVE), which is a Heun equation, is studied for commutativity. Some classical and modern results from the theory of transcendental numbers are used for the research.

description: GRO J2058+42 is a 195 s transient X-ray pulsar discovered in 1995 with BATSE. In 1996, RXTE located GRO J2058+42 to a 90% confidence error circle with a 4' radius. On 20 February 2004, the region including the error circle was observed with Chandra ACIS-I. No X-ray sources were detected within the error circle, however, 2 faint sources were detected in the ACIS-I field-of-view. We obtained optical observations of the brightest object, CXOU J205847.5+414637, that had about 64 X-ray counts and was just 0.3' outside the error circle. The optical spectrum contained a strong H alpha line and corresponds to an infrared object in the 2MASS catalog, indicating a Be/X-ray binary system. Pulsations were not detected in the Chandra observations, but similar flux variations and distance estimates suggest that CXOU J205847.5+414637 and GRO J2058+42 are the same object. We present results from the Chandra observation, optical observations, new and previously unreported RXTE observations, and a reanalysis of a ROSAT observation.

description: We study the derivation of generic high order macroscopic traffic models from a follow-the-leader particle description via a kinetic approach. First, we recover a third order traffic model as the hydrodynamic limit of an Enskog-type kinetic equation. Next, we introduce in the vehicle interactions a binary control modelling the automatic feedback provided by driver-assist vehicles and we upscale such a new particle description by means of another Enskog-based hydrodynamic limit. The resulting macroscopic model is now a Generic Second Order Model (GSOM), which contains in turn a control term inherited from the microscopic interactions. We show that such a control may be chosen so as to optimise global traffic trends, such as the vehicle flux or the road congestion, constrained by the GSOM dynamics. By means of numerical simulations, we investigate the effect of this control hierarchy in some specific case studies, which exemplify the multiscale path from the vehicle-wise implementation of a driver-assist control to its optimal hydrodynamic design.

Characterization of nuclear basic proteins in sperm and erythrocytes of vertebrates
Creators: name: Su, Hua Wei
Publisher: name: University of British Columbia
Year: 2009

description: I have examined the arginine-enriched nuclear basic proteins (NBPs) that condense chromatin in two kinds of transcriptionally inactive, terminally differentiated cells of non-mammalian vertebrates: sperm and erythrocytes. I have focused on the characterization of sperm nuclear basic proteins (SNBPs) in teleost fish and erythrocyte nuclear basic proteins (ENBPs) in reptiles and birds by electrophoresis, high pressure liquid chromatography and amino acid analysis to ask: 1) Is internal fertilization a constraint on the diversity of SNBPs seen in teleost fish and frogs? 2) Is bird linker histone H5 also present in alligator erythrocyte nuclei? I have found that internally fertilizing Xiphophorus helleri guentheri (swordtail), Xiphophorus maculatus (platyfish), Poecilia reticulata (guppy), Poecilia picta (guppy) and Cymatogaster aggregata (shiner perch) all contain protamines as their SNBPs. Amongst frogs, there is a sporadic reversion from protamines in the primitive, internally fertilizing frog Ascaphus truei, to sperm histones among several more advanced, externally fertilizing frogs (Kasinsky et al., 1999). This parallels a simplification of elongated introsperm to more rounded ectaquasperm in advanced neobatrachians that is regarded as a secondary reversion to external fertilization (Lee and Jamieson, 1992). However, characterization of SNBPs from the internally fertilizing neobatrachian frog Eleutherodactylus coqui shows the presence of four protamines. These results favor the hypothesis (Kasinsky, 1989) that fish and frogs with internal fertilization tend to select arginine-rich protamines as their SNBPs rather than sperm histones, whereas external fertilization is compatible with protamine-to-histone reversions in some advanced frogs. Is linker histone H5 unique to bird erythrocyte nuclei? H1°, another differentiationspecific linker histone in vertebrates, is not erythrocyte-specific. I have characterized ENBPs from Ictalurus punctatus (catfish), Rana catesbeiana (bullfrog), Chelonia mydas (sea turtle), Alligator mississippiensis (alligator), and Gallus gallus (chicken), as well as possible NBPs in the condensed nucleus of mouse normoblasts, the precursors of mature enucleated red blood cells. Alligator ENBPs appear to contain a linker histone H1°/H5 which is midway in the evolutionary trend from H1° to H5. This is consistent with the fact that alligators have a higher average blood pressure than sea turtles but much lower than in birds.
Excess Infrared Radiation from a Massive DAZ White Dwarf: GD362 - a Debris Disk?

description: We report the discovery of excess K-band radiation from a massive DAZ white dwarf star, GD362. Combining infrared photometric and spectroscopic observations, we show that the excess radiation cannot be explained by a stellar or substellar companion, and is likely to be caused by a debris disk. This would be only the second such system known, discovered 18 years after G29-38, the only single white dwarf currently known to be orbited by circumstellar dust. Both of these systems favor a model with accretion from a surrounding debris disk to explain the metal abundances observed in DAZ white dwarfs. Nevertheless, observations of more DAZs in the mid-infrared are required to test if this model can explain all DAZs.

description: Green industry sales are projected to total $40.4 billion in 1994. The industry ranked sixth in 1991 among farm commodity groups in total cash receipts, and over the past decade total receipts increased 10 percent per year. Net income per farm is the highest of all the commodity groups. Nevertheless, the sector has received scant federal support compared to other commodities. In spite of growth and significance, economic analysis and data availability and reliability have been limited. There is clear justification for increased efforts in data collection and economic analysis of this industry’s problems.

description: Industrial Symbiosis or By-Product Synergy is defined as a resource-sharing strategy that engages traditionally separate industries in a collective approach that involves a physical exchange of materials, water, energy, and by-products. Inspired by a real-world example of a paper-sugar symbiotic complex, we study the impact of competition on a firm’s willingness to implement an industrial symbiotic system. Sugar and paper firms are symbiotically connected, in the sense that the biomass from the manufacture of one product is used as a raw material for the second product, and vice-versa. We characterize the firm’s operational optimal/equilibrium decisions for its two products – both in the presence and absence of a symbiotic system – under monopoly as well as under competition. Our models capture the supply-side (e.g., a fixed production cost and changes in the variable production costs) as well as the demand-side (“green” consumers who value the nature-friendly production process) impact of implementing industrial symbiosis. Our results indicate that firms are more willing to implement industrial symbiosis when (a) the proportion of the green consumers is high; or (b) consumers’ appreciation for the green variants is high; or (c) variable production costs after implementation are lower. For a firm, competition from firms that only produce regular products encourages implementation of industrial symbiosis, whereas competition from firms that produce both regular and green products discourages it.

description: Using normalized Hermite functions, we construct bases in the space of square integrable functions on the unit circle ($L^2(\mathcal C)$) and in $l_2(\mathbb Z)$, which are related to each other by means of the Fourier transform and the discrete Fourier transform. These relations are unitary. The construction of orthonormal bases requires the use of the Gramm--Schmidt method. On both spaces, we have provided ladder operators with the same properties as the ladder operators for the one-dimensional quantum oscillator. These operators are linear combinations of some multiplication- and differentiation-like operators that, when applied to periodic functions, preserve periodicity. Finally, we have constructed riggings for both $L^2(\mathcal C)$ and $l_2(\mathbb Z)$, so that all the mentioned operators are continuous.

description: This paper examines the process of determining food safety and its implications for the scientific community. Of the two main categories of food safety, microorganisms and chemicals, the paper focuses on the latter. The importance of chemical use in agriculture is discussed along with public perceptions of such practices. The rapid introduction of new chemicals has outpaced the scientific community’s ability to test for toxicity and interpret its results. Testing and interpretation is confounded by the natural presence of chemicals in food. Limitations of animal experiments are discussed along with problems of calculating and communication risk, the latter being subject to public fear and outrage. The scientific community’s efforts to inform the public have been frustrated by food safety groups that aim to influence public perceptions of risk. The paper argues that the scientific community has an obligation to educate the public and policy-makers of the importance of good science in food safety.

description: Recent experiments on ultracold atomic alkali gases in a one-dimensional optical lattice have demonstrated the transition from a gas of soft-core bosons to a Tonks-Girardeau gas in the hard-core limit, where one-dimensional bosons behave like fermions in many respects. We have studied the underlying many-body physics through numerical simulations which accommodate both the soft-core and hard-core limits in one single framework. We find that the Tonks-Girardeau gas is reached only at the strongest optical lattice potentials. Results for slightly higher densities, where the gas develops a Mott-like phase already at weaker optical lattice potentials, show that these Mott-like short range correlations do not enhance the convergence to the hard-core limit.

description: Uncertainty quantification in neural networks gained a lot of attention in the past years. The most popular approaches, Bayesian neural networks (BNNs), Monte Carlo dropout, and deep ensembles have one thing in common: they are all based on some kind of mixture model. While the BNNs build infinite mixture models and are derived via variational inference, the latter two build finite mixtures trained with the maximum likelihood method. In this work we investigate the effect of training an infinite mixture distribution with the maximum likelihood method instead of variational inference. We find that the proposed objective leads to stochastic networks with an increased predictive variance, which improves uncertainty based identification of miss-classification and robustness against adversarial attacks in comparison to a standard BNN with equivalent network structure. The new model also displays higher entropy on out-of-distribution data.

description: A tunable microwave scattering device is presented which allows the controlled variation of Fano line shape parameters in transmission through quantum billiards. We observe a non-monotonic evolution of resonance parameters that is explained in terms of interacting resonances. The dissipation of radiation in the cavity walls leads to decoherence and thus to a modification of the Fano profile. We show that the imaginary part of the complex Fano q-parameter allows to determine the absorption constant of the cavity. Our theoretical results demonstrate further that the two decohering mechanisms, dephasing and dissipation, are equivalent in terms of their effect on the evolution of Fano resonance lineshapes.

description: Compton scattering in the bulk accretion flow of the accretion column in magnetic cataclysmic variables (mCVs) can significantly shift photon energies in the X-ray emission lines resulting from accretion shocks. In particular, Compton recoil can potentially broaden the 6.7 and 6.97 keV Fe K$α$ emission lines produced in the post-shock region, and contaminate the fluorescent 6.4 keV neutral Fe K$α$ line reflected off the white dwarf surface. We present nonlinear Monte Carlo simulations demonstrating these effects, and we discuss the interpretation of observed Fe K$α$ linewidths in mCVs in light of these new results. The implications for other accreting compact objects are also discussed.

description: We investigate the correspondence between generally covariant higher derivative scalar-tensor theory and spatially covariant gravity theory. The building blocks are the scalar field and spacetime curvature tensor together with their generally covariant derivatives for the former, and the spatially covariant geometric quantities together with their spatially covariant derivatives for the later. In the case of a single scalar degree of freedom, they are transformed to each other by gauge fixing and recovering procedures, of which we give the explicit expressions. We make a systematic classification of all the scalar monomials in the spatially covariant gravity according to the total number of derivatives up to $d=4$, and their correspondence to the scalar-tensor monomials. We discusse the possibility of using spatially covariant monomials to generate ghostfree higher derivative scalar-tensor theories. We also derive the covariant 3+1 decomposition without fixing any specific coordinate, which will be useful when performing a covariant Hamiltonian analysis.

description: This study examines the effect of various factors on the decision to consume home-delivered foods.

Specifically, the results suggest that less price-conscious, employed, higher-educated, white males within the 25-34 age group, in a household with a microwave oven, with smaller number of adults, but with children are more likely to purchase home-delivered food that others.

description: This case study examines the implementation of Total Quality Management (TOM) in two food processing firms. The two firms, which are separate divisions of a large food processor, used different implementation strategies, management leadership and employee empowerment. These strategies are compared on a strengths-and-weaknesses basis. The analysis shows that the context in which TQM is implemented is an important factor when planning such a dramatic strategic change and that the implementation of TQM or any other managerial innovation requires building teamwork and devotion of significant resources by all stakeholders in a company.

description: We prove the existence of dynamical delocalization for random Landau Hamiltonians near each Landau level. Since typically there is dynamical localization at the edges of each disordered-broadened Landau band, this implies the existence of at least one dynamical mobility edge at each Landau band, namely a boundary point between the localization and delocalization regimes, which we prove to converge to the corresponding Landau level as either the magnetic field or the disorder goes to zero.

Formation of a spiral galaxy in a major merger

Publisher: name: arXiv

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We use numerical simulations to examine the structure of merger remnants resulting from collisions of gas-rich spiral galaxies. When the gas fraction of the progenitors is small, the remnants structurally and kinematically resemble elliptical galaxies, in agreement with earlier work. However, if the progenitor disks are gas-dominated, new types of outcomes are possible. In fact, we show that a prominent disk may survive in certain cases. To illustrate this scenario, we analyze an extreme example with progenitor galaxies consisting of dark matter halos, pure gas disks, and no bulges, as might be appropriate for mergers at high redshifts. While rapid star formation triggered by tidal torques during the merger forms a central, rotating bulge in the remnant, not all the gas is consumed in the burst. The remaining gas cools very quickly and settles into an extended star-forming disk, yielding an object similar to a spiral galaxy, and not an early type galaxy. This is contrary to the usual view that major mergers invariably destroy disks. The morphological evolution of galaxies can therefore be more complicated than often assumed, and in particular, theoretical constraints based on the fragility of spiral disks need to be reevaluated.

Creators: name: Fawcett, Susan Margaret
Publisher: name: University of British Columbia
Year: 2009

description: In both the research and clinical arenas, the measurement of children's progress in language therapy is commonly completed by the administration of formal, norm-referenced tests. This is despite the fact that more naturalistic or informal measures, such as language sample analyses, may be better suited to this assessment task. This issue may be particularly relevant in the assessment of young children with autism due to their unique set of communication challenges. The question addressed in the present study, then, is whether the data resulting from both types of measures, formal and informal, provides convergent information about the progress made in several areas of expressive communication by seven children with autism. Seven children with autism were assessed using both types of tools at two successive data points, and the information gleaned from each type of assessment was then compared. It was found that, in the majority of cases, the two data sets did not converge on the type of information they provided about how the children progressed as a result of therapy. It appeared as though this was due to two factors: child factors, such as not having the prerequisite test-taking abilities to earn scores on the formal measures, and assessment tool factors, such as some language domains not being addressed adequately by formal tests.

description: Environmental concerns about pesticide usage in traditional production systems are prompting vegetable producers to consider alternative systems. Research results from a multi-year study on eggplant in southern Georgia compare two alternative production technologies to the conventional rye cover crop technology. Alternative technologies utilize beneficial insect principles as substitutes for conventional pesticide controls. Using field data, eggplant production budgets are developed to generate net return estimates under each system. Cost reductions achieved by using alternative technologies are not sufficient to offset the reduced yields and returns generated from these technologies. Cash input requirements for alternative systems suggest potential for limited resource producers.

description: Abstract:Purpose: Freight forwarders faces a challenging environment of high market volatility and margin compression risks. Hence, strategic consideration is given to undertaking capacity management and transport asset ownership to achieve longer term cost leadership. Doing so will also help to address management issues, such as better control of potential transport disruptions, improve scheduling flexibility and efficiency, and provide service level enhancement.
Design/methodology/approach: The case company currently has truck resource which is unprofitable, and the firm’s schedulers are having difficulty optimizing the loading capacity. We apply Genetic Algorithm (GA) to undertake volumetric optimization of truck capacity and to build an easy-to-use platform to help determine potential costing savings that can be attained, and whether if the business should expand its internal truck fleet.

Findings: Our analysis suggests that the case company’s truck resource is underutilized by about two-thirds of capacity. Through a proposed mathematical model and GA heuristic, the case company can potentially save up to S$567K per annum.
Value: By using a simple GA and incorporating a visually appealing user interface, we have helped a freight forwarder improve her financial and operational efficiency. The game changer is the scalability of the solution to include more resource optimization across the fleet and across more freight forwarding firms.

description: Mandelbrot introduced the concept of fractals to describe the non-Euclidean shape of many aspects of the natural world. In the time series context he proposed the use of fractional Brownian motion (fBm) to model non-negligible temporal persistence, the "Joseph Effect"; and Levy flights to quantify large discontinuities, the "Noah Effect". In space physics, both effects are manifested in the intermittency and long-range correlation which are by now well-established features of geomagnetic indices and their solar wind drivers. In order to capture and quantify the Noah and Joseph effects in one compact model we propose the application of the "bridging" fractional Levy motion (fLm) to space physics. We perform an initial evaluation of some previous scaling results in this paradigm, and show how fLm can model the previously observed exponents. We suggest some new directions for the future.
description: Please note that our identifications of FBM and "FLM" with fractional time derivatives, made just before equation 2), were in error. See http://www.bibsonomy.org/bibtex/29f4390d7d0965c4c7371b02ddd8f6c7b/statphys23

description: We investigate magnetic properties of a two-dimensional periodic structure with Ising spins and antiferromagnetic nearest neighbor interaction. The structure is topologically equivalent to the Archimedean (3,12^2) lattice. The ground state energy is degenerate. In some ground states, the spin structure is translationally invariant, with the same configuration in each unit cell. Numerical results are reported on specific heat and static magnetic usceptibility against temperature. Both quantities show maxima at temperature T>0. They reveal some sensitivity on the initial state in temperatures where the Edwards--Anderson order parameter is positive. For zero temperature and low frequency of the applied field, the magnetic losses are negligible. However, the magnetization curve displays some erratic behavior due to the metastable states.

description: This paper critically examines linkages between alternative farming practices and environmental quality. Environmental impacts of high-yield farming are contrasted to those of low-yield farming. Traditional low-yield farming systems, while being promoted by environmental groups, have resulted in massive famine, higher cancer rates, soil erosion, and losses in wildlife habitat. Organic farming and other low-yield systems are land intensive and invade marginal farmland, thereby destroying wildlife habitat and biodiversity. Low-yield farming has not and cannot produce enough food to meet the food needs of the world’s population. By contrast, high-yield farming minimizes land use for food production and increase the availability of land for wildlife habitat and biodiversity. High-yield farming has contributed to economic development and lower birth rates, thereby reducing population growth. The environment risks from high-yield farming are considered low and have been declining. The benefits of high-yield farming can be maximized with agricultural research and free trade in farm products.

description: Auction market users and operators were surveyed regarding their source and use of livestock auction price information. Although important for marketing and to a lesser extent production decisions, only 30 percent preferred publicly reported prices over reports from market operators or other sources. The small share of market users willing to pay for public price reports suggests acceptable substitutes are available. Based on these results it is unlikely that user fees will be able to replace the current level of public support for auction market price reporting.

description: We present an extension of the Goldstone-boson-exchange constituent quark model including additional interactions beyond the ones used hitherto. For the hyperfine interaction between the constituent quarks we assume pseudoscalar, vector, and scalar meson exchanges and consider all relevant force components produced by these types of exchanges. The resulting model, which corresponds to a relativistic Poincare-invariant Hamiltonian (or equivalently mass operator), provides a unified framework for a covariant description of all light and strange baryons. The ground states and resonances up to an excitation energy of about 2 GeV are reproduced in fair agreement with phenomenology, with the exception of the first excitations above the Lambda and Xi ground states.

description: We present the results of UBV imaging of a large sample of irregular galaxies: 94 Im systems, 24 Blue Compact Dwarfs (BCDs), and 18 Sm galaxies. We also include JHK imaging of 41 of these galaxies. The sample spans a large range in galactic parameters. Ellipse fit axial ratios, inclinations, and position angles are derived, integrated photometry and azimuthally-averaged surface photometry profiles are determined, and exponential fits give the central surface brightnesses, scale lengths, and isophotal and half-power radii. These data are used to address the shapes of Im galaxies, look for clues to past interactions in large-scale peculiarities, examine the nature and consequences of bars, study color gradients and large-scale color variations, and compare the exponential disk profiles of the young and old stellar components. For example, color gradients exhibit a great variety and not all passbands are correlated. Bars are associated with higher star formation rates. Many irregulars show a double exponential radial light profile that is steeper in the outer parts, and these are reproduced by a new model of star formation that is discussed in a companion paper. Some galaxies, primarily BCDs, have double exponentials that are steeper (and bluer) in the inner parts, presumably from centralized star formation. Im-types have thicker, less-prominent dust layers than spiral galaxies because of their lower average surface densities and midplane extinctions.
