Subjects: subject: Nuclear Experiment (nucl-ex)
subject: FOS: Physical sciences

description: Preliminary femtoscopic results on identical pions from high statistics data set of Au+Au collisions at sqrt{s_NN}=200 GeV taken during the fourth RHIC run are presented. The measured three-dimensional correlation function is studied at low relative momenta using the Gaussian parametrization and the Levy stable parametrization. The latter is expected to better describe the data. As the results show, both parametrizations underestimate the peak of the measured correlation function equally.

description: In 2003 an agreement was finalized to instigate arguably the most significant reform of the European Union's (EU) Common Agricultural Policy (CAP) since its inception. In the Luxembourg Agreement many of the direct payments that have been linked to production are decoupled and instead provided in the form of a land-based payment. The reforms did not include any significant changes to either EU border support or the ability of the EU to utilize export subsidies that have been widely criticized by other nations. Even though the reforms do not directly address trade in agricultural products it is argued that World Trade Organization (WTO) concerns played a significant role in the designs of the reforms. In this paper an analysis of the Luxembourg reforms and the European proposal for agriculture under the WTO is presented. The results are used as the basis for a discussion of the interaction of the WTO and CAP reform and the implications for the agricultural sector in the EU.

description: A transform between functions in R and functions in Zd is used to define the analogue of number and coherent states in the context of finite d-dimensional quantum systems. The coherent states are used to define an analytic representation in terms of theta functions. All states are represented by entire functions with growth of order 2, which have exactly d zeros in each cell. The analytic function of a state is constructed from its zeros. Results about the completeness of finite sets of coherent states within a cell are derived.

description: Ebola virus disease (formerly called Ebola Hemorrhagic Fever) caused by Ebola virus of the family Flaviviridae, is a severe and fatal disease in humans and primates. First outbreak occurred in Democratic Republic of the Congo (formerly Zaire) and then in several African countries. Compared to the cumulative sum of past cases in 36 years (1976-2012), 2,232 infected people and 1,503 deaths counted which is now over ten times the total number infections and over six times the total number of deaths. One of the reasons that why Ebola is so dangerous is that its symptoms are varied and appear quickly, which resembles to that of hemorrhagic fever and not rapidly diagnosed. Ebola Virus Disease (EVD) can be transmitted between humans through direct contact with bodily fluids (e.g., blood, sweat) from an infected person or sharing contaminated objects. The vaccines cAd3-ZEBOV and rVSV has proved to an extent against primates but human beings are still the subject under consideration.

description: We present observations of dwarf nova oscillations (DNOs), longer period dwarf nova oscillations (lpDNOs), and quasi-periodic oscillations (QPOs) in 13 cataclysmic variable stars (CVs). In the six systems WW Cet, BP CrA, BR Lup, HP Nor, AG Hya, and V1193 Ori, rapid, quasi-coherent oscillations are detected for the first time. For the remainder of the systems discussed we have observed more classes of oscillations, in addition to the rapid oscillations they were already known to display, or previously unknown aspects of the behaviour of oscillations. The period of a QPO in RU Peg is seen to change by 84% over ten nights of the decline from outburst--the largest evolution of a QPO period observed to date. A period-luminosity relation similar to the relation that has long been known to apply to DNOs is found for lpDNOs in X Leo; this is the first clear case of lpDNO frequency scaling with accretion luminosity. WX Hyi and V893 Sco are added to the small list of dwarf novae that have shown oscillations in quiescence.

Massive elliptical galaxies in X-rays: the role of late gas accretion

description: We present a new chemical evolution model meant to be a first step in the self-consistent study of both optical and X-ray properties of elliptical galaxies. Detailed cooling and heating processes in the interstellar medium are taken into account using a mono-phase one-zone treatment which allows a more reliable modelling of the galactic wind regime with respect to previous work. The model successfully reproduces simultaneously the mass-metallicity, colour-magnitude, the L_X - L_B and the L_X - T relations, as well as the observed trend of the [Mg/Fe] ratio as a function of sigma, by adopting the prescriptions of Pipino & Matteucci (2004) for the gas infall and star formation timescales. We found that a late secondary accretion of gas from the environment plays a fundamental role in driving the L_X - L_B and L_X - T relations and can explain their large observational scatter. The iron discrepancy, namely the too high predicted iron abundance in X-ray haloes of ellipticals compared to observations, still persists. On the other hand, we predict [O/Fe] in the ISM which is in good agreement with the most recent observations. We suggest possible mechanisms acting on a galactic scale which may solve the iron discrepancy. In particular, mixing of gas driven by AGNs may preserve the gas mass (and thus the X-ray luminosity) while diluting the iron abundance. New predictions for the amounts of iron, oxygen and energy ejected into the intracluster medium (ICM) are presented and we conclude that Type Ia supernovae (SNe Ia) play a fundamental role in the ICM enrichment. SNe Ia activity, in fact, may power a galactic wind lasting for a considerable amount of the galactic lifetime, even in the case for which the efficiency of energy transfer into the ISM per SN Ia event is less than unity.

description: Proposals for marginal cost water pricing have often been found to be politically infeasible because current users will have to pay a higher price even though future users will be better off. We show how efficiency pricing can be rendered Pareto-improving, and thus politically feasible, by compensating the users suffering a loss due to higher prices. We also provide a method for determining efficient spatial and inter-temporal water management for a system with consumption at significantly different elevations supplied from a renewable coastal aquifer, which is subject to salinity if over-extracted.

description: We study the structure of solutions of the one-dimensional non-linear pseudodifferential equation describing the dynamics of the $p$-adic open string for the scalar tachyon field $p^{\frac12\partial^2_t}Φ=Φ^p$. We elicit the role of real zeros of the entire function $Φ^p(z)$ and the behaviour of solutions $Φ(t)$ in the neighbourhood of these zeros. We point out that discontinuous solutions can appear if $p$ is even. We use the method of expanding the solution $Φ$ and the function $Φ^p$ in the Hermite polynomials and modified Hermite polynomials and establish a connection between the coefficients of these expansions (integral conservation laws). For $p=2$ we construct an infinite system of non-linear equations in the unknown Hermite coefficients and study its structure. We consider the 3-approximation. We indicate a connection between the problems stated and the non-linear boundary-value problem for the heat equation.

Tolerance versus synaptic noise in dense associative memories

Publisher: name: arXiv
Year: 2020
Subjects: subject: Disordered Systems and Neural Networks (cond-mat.dis-nn)

description: The retrieval capabilities of associative neural networks can be impaired by different kinds of noise: the fast noise (which makes neurons more prone to failure), the slow noise (stemming from interference among stored memories), and synaptic noise (due to possible flaws during the learning or the storing stage). In this work we consider dense associative neural networks, where neurons can interact in $p$-plets, in the absence of fast noise, and we investigate the interplay of slow and synaptic noise. In particular, leveraging on the duality between associative neural networks and restricted Boltzmann machines, we analyze the effect of corrupted information, imperfect learning and storing errors. For $p=2$ (corresponding to the Hopfield model) any source of synaptic noise breaks-down retrieval if the number of memories $K$ scales as the network size. For $p>2$, in the relatively low-load regime $K \sim N$, synaptic noise is tolerated up to a certain bound, depending on the density of the structure.

description: Consumer attitudes towards genetically modified foods (GMFs) play a crucial role in the development of the technology. Both government and food manufacturers of agricultural products in the US and China are optimistic about the potential market for these foods. This paper compares two national consumer surveys conducted in the US and China. To determine if influential factors are driving consumers' attitudes towards GM plant and animal products in both countries a binary logic model is used. Findings suggest that for the majority of American and Chinese consumers while their overall knowledge of GM food is low, their attitudes toward the technology are generally supportive. Consumers in both countries are more accepting of GM plant products then GM animal products. Interestingly, gender, living place, and awareness of GM foods have similar significant effects for both countries.

description: The RPA long range correlations are known to play a significant role in understanding the depletion of single particle-hole states observed in (e, e') and (e, e'p) measurements. Here the Random Phase Approximation (RPA) theory, implemented using the D1S force is considered for the specific purpose of building correlated ground states and related one-body density matrix elements. These may be implemented and tested in a fully microscopic optical model for NA scattering off doubly-closed-shell nuclei. A method is presented to correct for the correlations overcounting inherent to the RPA formalism. One-body density matrix elements in the uncorrelated (i.e. Hartree-Fock) and correlated (i.e. RPA) ground states are then challenged in proton scattering studies based on the Melbourne microscopic optical model to highlight the role played by the RPA correlations. Effects of such correlations which deplete the nuclear matter at small radial distance (r $

description: This paper develops a framework to link the expected utility analysis to real options models in order to capture the joint effects of risk aversion and irreversibility associated with real investments. It aims at modifying the theory of investment under uncertainty by incorporating decision makers' risk preferences and allows explicitly analyzing the impacts of risk aversion, uncertainty and irreversibility on decisions such as investment and resource allocations. It addresses the shortcomings of the commonly used expected utility and investment under uncertainty models be generalizing the theory of irreversible investment under uncertainty by allowing for risk-averse investors. We found that uncertainty, irreversibility and risk aversion are important determinants of the optimal timing of irreversible decisions. Ignoring risk preferences in real options models would lead to over or underestimation of magnitude of investments.

The paper reports the first experimental determination of the low-lying phonon dispersion curves for this alloy system. We find that the frequencies of the TA$_2$ modes are relatively low. This branch exhibits an anomaly (dip) at a wave number $ξ_{0} ={1/3}\approx 0.33$, which softens with decreasing temperature. Associated with this anomalous dip at $ξ_{0}$, an elastic central peak scattering is also present. We have also observed satellites due to the magnetic ordering.

description: Using the 2dF multi-fibre instrument on the AAT, moderate resolution spectra have been obtained for a large sample of stars on the main sequence and at the turnoff in the unusual globular cluster omega Centauri. We investigate the behaviour of CH, CN and SrII line strength indices as a function of overall abundance for the main sequence sample. A number of stars do not follow the relations defined by the majority. These anomalous objects can be categorised into (at least) three types. (1) Carbon enhanced stars, which represent about 5% of the sample, and which are found at all metallicities. Spectrum synthesis calculations show that the atmospheres of these stars are typically enhanced in C by factors of between 3 and 10. (2) Nitrogen enhanced stars, revealed for [Fe/H] > -1.3 by strong CN indices, which make up ~40% of the cluster main sequence population above this metallicity. These stars are enhanced in N by factors of up to 100. Our data, however, provide no constraints of their relative numbers at lower [Fe/H]. (3) Stars with enhancements of the s-process element Sr by factors of 30 to 60. The possible origins for these abundance anomalies are discussed.

Entretanto, a maior proporção de indivíduos contaminados foi registrada para a espécie grauçá (Ocypode quadrata), na praia dos Milionários, onde 11 dos 20 caranguejos analisados tiveram contato direto com o óleo. As partes do corpo dos animais onde os vestígios de óleo foram encontrados (quelas/pinças e peças bucais) sugerem que a maior parte dos caranguejos tentaram alguma interação alimentar com o óleo. Em um dos indivíduos, apesar de não apresentar indícios externos de contato com o óleo, foi encontrado pequeno vestígio de óleo no estômago do animal. No manguezal do Cururupe, que recebeu uma quantidade de óleo muito inferior à da praia dos Milionários, o número de caranguejos com vestígios de óleo foi também muito menor. Apenas um dos 41 caranguejos analisados apresentou vestígio de óleo. Esse exemplar é pertencente a uma das espécies de chama-maré (Leptuca leptodactyla). Nenhum dos indivíduos de aratu, uma espécie muito consumida na região, apresentou vestígio de óleo na área estudada.

description: Spin-torque ferromagnetic resonance (ST-FMR) is a common method used to measure spin-orbit torques (SOTs) in heavy metal/ferromagnet bilayer structures. In the course of a measurement, other resonant processes such as spin pumping (SP) and heating can cause spin current or heat flows between the layers, inducing additional resonant voltage signals via the inverse spin Hall effect (ISHE) and Nernst effects (NE). In the standard ST-FMR geometry, these extra artifacts exhibit a dependence on the angle of an in-plane magnetic field that is identical to the rectification signal from the SOTs. We show experimentally that the rectification and artifact voltages can be quantified separately by measuring the ST-FMR signal transverse to the applied current (i.e., in a Hall geometry) in addition to the usual longitudinal geometry. We find that in Pt (6 nm)/CoFeB samples the contribution from the artifacts is small compared to the SOT rectification signal for CoFeB layers thinner than 6 nm, but can be significant for thicker magnetic layers. We observe a sign change in the artifact voltage as a function of CoFeB thickness that we suggest may be due to a competition between a resonant heating effect and the SP/ISHE contribution.

description: With a view to understanding extended-BMS symmetries in the framework of the $AdS_4/CFT_3$ correspondence, asymptotically AdS geometries are constructed with null impulsive shockwaves involving a discontinuity in superrotation parameters. The holographic dual is proposed to be a two-dimensional Euclidean defect conformal field localized on a particular timeslice in a three-dimensional conformal field theory on de Sitter spacetime. The defect conformal field theory generates a natural action of the Virasoro algebra. The large radius of curvature limit $\ell\to\infty$ yields spacetimes with nontrivial extended-BMS charges.

description: Field-channelled accretion flows occur in a variety of astrophysical objects, including T Tauri stars,magnetic cataclysmic variables and X-ray pulsars. We consider a curvilinear coordinate system and derive a general hydrodynamic formulation for accretion onto stellar objects confined by a stellar dipole magnetic field. The hydrodynamic equations are solved to determine the velocity, density and temperature profiles of the flow. We use accreting magnetic white-dwarf stars as an illustrative example of astrophysical applications. Our calculations show that the compressional heating due to the field geometry is as important as radiative cooling and gravity in determining the structure of the post-shock flow in accreting white-dwarf stars. The generalisation of the formulation to accretion flows channelled by higher-order fields and the applications to other astrophysical systems are discussed.

description: Correlations of like-sign pion pairs emerging from proton-antiproton collisions are analysed in the two-dimensional (q_L,q_T) decomposition of the three-momentum difference q. While the data cannot be adequately represented by gaussian, exponential, power-law or Edgeworth parametrisations, more elaborate ones such as Levy and an exponential with a cross term do better. A two-scale model using a hard cut to separate small and large scales may indicate a core that is more prolate than the halo. Consideration not only of the interference peak at small (q_L,q_T), but also of the shape of the correlation distribution at intermediate momentum differences is crucial to understanding the data.

description: Os resultados dessa primeira análise indicam que, em termos gerais, dos 61 caranguejos analisados, pelo menos 20% tiveram contato direto com o óleo. Entretanto, a maior proporção de indivíduos contaminados foi registrada para a espécie grauçá (Ocypode quadrata), na praia dos Milionários, onde 11 dos 20 caranguejos analisados tiveram contato direto com o óleo. As partes do corpo dos animais onde os vestígios de óleo foram encontrados (quelas/pinças e peças bucais) sugerem que a maior parte dos caranguejos tentaram alguma interação alimentar com o óleo. Em um dos indivíduos, apesar de não apresentar indícios externos de contato com o óleo, foi encontrado pequeno vestígio de óleo no estômago do animal. No manguezal do Cururupe, que recebeu uma quantidade de óleo muito inferior à da praia dos Milionários, o número de caranguejos com vestígios de óleo foi também muito menor. Apenas um dos 41 caranguejos analisados apresentou vestígio de óleo. Esse exemplar é pertencente a uma das espécies de chama-maré (Leptuca leptodactyla). Nenhum dos indivíduos de aratu, uma espécie muito consumida na região, apresentou vestígio de óleo na área estudada.

Productivity Analysis

description: Productivity growth in the Canadian processed food industry has lagged behind that in the United States because of a relatively low rate of R&D investment. Although U.S. firms generally have a technological advantage over Canadian firms, marginal rates of return to R&D are higher in Canada.

description: High spatial resolution observations of the 12CO(1-0), HCN(1-0), HCO+(1-0), and 13CO(1-0) molecular lines toward the luminous infrared merger NGC 6240 have been performed using the Nobeyama Millimeter Array and the RAINBOW Interferometer. All of the observed molecular emission lines are concentrated in the region between the double nuclei of the galaxy. However, the distributions of both HCN and HCO+ emissions are more compact compared with that of 12CO, and they are not coincident with the star-forming regions. The HCN/12CO line intensity ratio is 0.25; this suggests that most of the molecular gas between the double nuclei is dense. A comparison of the observed high HCN/13CO intensity ratio, 5.9, with large velocity gradient calculations suggests that the molecular gas is dense [n(H_2)=10^{4-6} cm^-3] and warm (T_kin>50 K). The observed structure in NGC 6240 may be explained by time evolution of the molecular gas and star formation, which was induced by an almost head-on collision or very close encounter of the two galactic nuclei accompanied with the dense gas and star-forming regions.

Genetic variation for resource use efficiencies in lodgepole pine
Creators: name: Smets, Pia
Publisher: name: University of British Columbia
Year: 2009

description: This study investigates genetic variation for resource-use efficiencies in lodgepole pine (Pinus contorta Dougl. ssp. contorta and ssp. latifolia). Because of the species' frequent occurrence on marginal sites, these resource-use efficiencies are expected to play an important role in its adaptation and evolution. A deeper understanding of the patterns of adaptation is needed to enable a more fine-tuned management of the existing genetic variation in the breeding program. Since natural selection acts on phenotypes, both genotype and environment are considered jointly. Since the effects of genotypes, traits and environmental factors may not be separable, all of these elements are observed jointly in a controlled experiment. Under the null hypothesis, traits evolve independently to single environmental variables. Under the alternative hypothesis, there is an integrated physiological system that differs among genotypes, that reacts as a whole to multiple environmental variables and evolves as a whole in adaptation to those source variables. Water-use efficiency and nitrogen-use efficiency were measured on one-year old seedlings of lodgepole pine in the controlled environment of the greenhouse. These traits were observed over a range of environments, created by controlled levels of available water and nitrogen. A preliminary experiment was set up in 1996 with provenances of lodgepole pine, mainly to proofrun the nursery techniques, to confirm the existence of genetic variation for resource-use efficiencies, to determine sources of variation in the experiment, and to investigate separability of the effects in general. A second experiment was set up in 1997, using selected families incorporating a more continuous range of variation for source variables than is possible with a provenance structure. It had the added advantage that 10-year field site data are available for comparison. Genetic variation exists for mean trait expression as well as for plasticity for both water-use efficiency and nitrogen-use efficiency. Genetic variability within populations tends to be high despite pronounced differentiation of populations. Populations are somewhat adapted to their local environments, but not very precisely: the breeder is not limited to specific seed sources in order to ensure adaptation to marginal sites. Genetic correlations do not indicate conflicts between selection for growth and adaptation. Genotype-environment rank order change exists for several traits and no simple, consistent patterns for it emerge. Patterns of trait integration vary across environments. Especially nitrogen deficiency can drastically change trait relationships. Thus, multiple environmental factors and multiple traits act jointly to create a large number of environmental niches, resulting in more opportunities for the maintenance of genetic variation. The result of this complex process is that patterns of adaptation for single traits, if present, are not narrowly defined.

description: Flooded rice production is crucial to global food security, but there are associated environmental concerns. In particular, it is a significant source of methane and nitrous oxide emissions and a large consumer of water resources, while arsenic, cadmium and lead levels in the grain are a serious health concern. There is also a tendency to use more organic fertilisers to close nutrient cycles, posing a threat of even higher greenhouse gas emissions and grain arsenic levels. It has been shown that alternate wetting and drying (AWD) water management reduces both water use and greenhouse gas emissions, but success at maintaining yields varies. This study tested the effect of early AWD (e-AWD) versus continuous flooding (CF) water management practices on grain yields, greenhouse gas emissions and grain arsenic, cadmium and lead levels in a split plot field experiment with organic fertilisers under organic management. The e-AWD water regime showed no difference in yield for the organic treatments. Yields significantly increased by 5 to 16 percent in the combination treatments. Root biomass and root length increased in the e-AWD treatments up to 72 and 41 percent, respectively. The e-AWD water regime reduced seasonal methane emissions by 71 to 85 percent for organic treatments and by 51 to 76 percent for combination treatments; this was linked to a 15 to 47 percent reduction in dissolved organic carbon. Nitrous oxide emissions increased by 23 to 305 percent but accounted for less than 20 percent of global warming potential. Area and yield scaled global warming potentials were reduced by 67 to 83 percent. The e-AWD regime altered soil redox potentials, resulting in a reduction in grain arsenic and lead concentrations of up to 66 % and 73 % respectively. Grain cadmium levels were also reduced up to 33 % in organic treatments.

description: This research is about the development a fuzzy decision support system for the diagnosis of coronary artery disease based on evidence. The coronary artery disease data sets taken from University California Irvine (UCI) are used. The knowledge base of fuzzy decision support system is taken by using rules extraction method based on Rough Set Theory. The rules then are selected and fuzzified based on information from discretization of numerical attributes. Fuzzy rules weight is proposed using the information from support of extracted rules. UCI heart disease data sets collected from U.S., Switzerland and Hungary, data from Ipoh Specialist Hospital Malaysia are used to verify the proposed system. The results show that the system is able to give the percentage of coronary artery blocking better than cardiologists and angiography. The results of the proposed system were verified and validated by three expert cardiologists and are considered to be more efficient and useful.

description: Environmental policies generally address problems associated with ill-defined property rights. Our framework describes property rights "regimes" as functions of the degree of consolidation of rights to an asset and of the parties holding those rights. Efficient resource use occurs if welfare gains from regime switches offset endogenous transaction costs.

description: The severe acute respiratory syndrome COVID-19 has been in the center of the ongoing global health crisis in 2020. The high prevalence of mild cases facilitates sub-notification outside hospital environments and the number of those who are or have been infected remains largely unknown, leading to poor estimates of the crude mortality rate of the disease. Here we use a simple model to describe the number of accumulated deaths caused by COVID-19. The close connection between the proposed model and an approximate solution of the SIR model provides a system of equations whose solutions are robust estimates of epidemiological parameters. We find that the crude mortality varies between $10^{-4}$ and $10^{-3}$ depending on the severity of the outbreak which is lower than previous estimates obtained from laboratory confirmed patients. We also estimate quantities of practical interest such as the basic reproduction number and the expected number of deaths in the asymptotic limit with and without social distancing measures and lockdowns, which allow us to measure the efficiency of these interventions.
