This criterion summarizes proofs of known results and new applications. It also frees the hypothesis from the assumption that the units are contained in a product system of time ordered Fock modules.

description: Selecting the right compiler optimisations has a severe impact on programs' performance. Still, the available optimisations keep increasing, and their effect depends on the specific program, making the task human intractable. Researchers proposed several techniques to search in the space of compiler optimisations. Some approaches focus on finding better search algorithms, while others try to speed up the search by leveraging previously collected knowledge. The possibility to effectively reuse previous compilation results inspired us toward the investigation of techniques derived from the Recommender Systems field. The proposed approach exploits previously collected knowledge and improves its characterisation over time. Differently from current state-of-the-art solutions, our approach is not based on performance counters but relies on Reaction Matching, an algorithm able to characterise programs looking at how they react to different optimisation sets. The proposed approach has been validated using two widely used benchmark suites, cBench and PolyBench, including 54 different programs. Our solution, on average, extracted 90% of the available performance improvement 10 iterations before current state-of-the-art solutions, which corresponds to 40% fewer compilations and performance tests to perform.

description: El carácter voluntario de los programas agroambientales hace que su éxito dependa del grado de aceptación por parte de los agricultores. La decisión de participación es compleja, ya que está condicionada por una gran variedad de factores. Este estudio amplía el análisis de la elección de la mejor alternativa de gestión para una explotación agraria en presencia de programas agroambientales analizando de manera explícita el papel que juega el capital social. Los resultados señalan la importancia de este concepto, tanto en medidas con escasos requisitos de cambio como en medidas más exigentes para los agricultores.

description: The chiral algebra of tetrahedral molecules, derived from Fischer projections, is discussed in the framework of quantum mechanics. A quantum chiral algebra is obtained whose operators, acting as rotations or inversions, commute with the Hamiltonian of the system. It is shown that energy and chirality eigenstates are strictly related through the Heisenberg relations, while chirality operators conserve parity eigenstates.

description: We propose the design of low strained and energetically favourable mono and bilayer graphene overlayer on anatase TiO$_2$ (001) surface and examined the electronic structure of the interface with the aid of first principle calculations. In the absence of hybridization between surface TiO$_2$ and graphene states, dipolar fluctuations govern the minor charge transfer across the interface. As a result, both the substrate and the overlayer retain their pristine electronic structure. The interface with the monolayer graphene retains its gapless linear band dispersion irrespective of the induced epitaxial strain. The potential gradient opens up a few meV bandgap in the case of Bernal stacking and strengthens the interpenetration of the Dirac cones in the case of hexagonal stacking of the bilayer graphene. The difference between the macroscopic average potential of the TiO$_2$ and graphene layer(s) in the heterostructure lies in the range 3 to 3.13 eV, which is very close to the TiO$_2$ bandgap ($\sim$ 3.2 eV). Therefore, the proposed heterostructure will exhibit enhanced photo-induced charge transfer and the graphene component will serve as a visible light sensitizer.

description: Nonlocality, one of the most puzzling features of multipartite quantum correlation, has been identified as a useful resource for device-independent quantum information processing. Motivated by the resource theory of quantum entanglement recently an operational framework have been proposed by Gallego et al. [\href{https://doi.org/10.1103/PhysRevLett.109.070401}{Phys. Rev. Lett. 109, 070401 (2012)}] and Bancal et al. [\href{https://doi.org/10.1103/PhysRevA.88.014102}{Phys. Rev. A 88, 014102 (2013)}] that characterizes the nonlocal resource present in multipartite quantum correlations. While the bipartite no-signaling correlations allows a dichotomous classification -- local vs. nonlocal, in multipartite scenario the authors have shown existence of several types of nonlocality that are inequivalent under the proposed operational framework. In this work we present a finer characterization of multipartite no-signaling correlations based on the same operational framework. We also clarify a statement in Gallego et al.'s work that could be misinterpreted and make the conclusions of that work more precise here.

Early numeracy profiles of arithmetic disability and arithmetic and reading disability subtypes
Creators: name: Vukovic, Rose Kathy
Publisher: name: University of British Columbia
Year: 2009

description: The present study investigated the kindergarten and grade 1 numeracy profiles of arithmetic disability (AD) and reading and arithmetic disability (RAD) subtypes. The results showed that children with RAD exhibited a different profile than children with AD in both kindergarten and in grade 1. In kindergarten, children with RAD knew fewer letters and numbers, were more developmentally delayed in their informal skills than AD children and had a memory span deficit. In grade 1, RAD children continued to be characterized by memory span and informal skill deficits. RAD children were also significantly deficient in mathematical problem solving and reading. The kindergarten predictors of grade 1 numeracy achievement were also investigated. The present study found support for the role of informal skills, working memory, spatial tasks and phoneme deletion in grade 1 numeracy achievement. Future research is needed to determine the predictive power of kindergarten skills to later numeracy skills.

We show that if an eavesdropper performs a coherent measurement on many quantum ancilla states simultaneously, classical methods of secure key distillation are less effective than quantum entanglement distillation protocols. We also show that certain Bell diagonal states are resistant to any attempt of incoherent eavesdropping.

description: We study the two-dimensional extension of the Su-Schrieffer-Heeger model in its higher order topological insulator phase, which is known to host corner states. Using the separability of the model into a product of one-dimensional Su-Schrieffer-Heeger chains, we analytically describe the eigen-modes, and specifically the zero-energy level, which includes states localized in corners. We then consider networks with disordered hopping coefficients that preserve the chiral (sublattice) symmetry of the model. We show that the corner mode and its localization properties are robust against disorder if the hopping coefficients have a vanishing flux on appropriately defined super plaquettes. We then show how this model with disorder can be realised using an acoustic network of air channels, and confirm the presence and robustness of corner modes.

description: Resonant magnetic modes with odd and even symmetries were studied by inelastic neutron scattering experiments in the bilayer high-$T_c$ superconductor $\rm Y_{1-x}Ca_{x}Ba_2Cu_3O_{6+y}$ over a wide doping range. The threshold of the spin excitation continuum in the superconducting state, deduced from the energies and spectral weights of both modes, is compared with the superconducting d-wave gap, measured on the same samples by electronic Raman scattering in the $B_{1g}$ symmetry. Above a critical doping level of $δ\simeq 0.19$, both mode energies and the continuum threshold coincide. We find a simple scaling relationship between the characteristic energies and spectral weights of both modes, which indicates that the resonant modes are bound states in the superconducting energy gap, as predicted by the spin-exciton model of the resonant mode.

description: The present work studies the robustness of certain basic homoclinic motions in an equilateral restricted four body problem. The problem can be viewed as a two parameter family of conservative autonomous vector fields. The main tools are numerical continuation techniques for homoclinic and periodic orbits, as well as formal series methods for computing normal forms and center stable/unstable manifold parameterizations. After careful numerical study of a number of special cases we formulate several conjectures about the global bifurcations of the homoclinic families.

Light curves and polarization of accretion- and nuclear-powered millisecond pulsars

Publisher: name: arXiv
Year: 2004
Subjects: subject: Astrophysics (astro-ph)

description: We study theoretical X-ray light curves and polarization properties of accretion-powered millisecond pulsars. We assume that the radiation is produced in two antipodal spots at the neutron star surface which are associated with the magnetic poles. We compute the angle-dependent intensity and polarization produced in an electron-scattering dominated plane-parallel accretion shock in the frame of the shock. The observed flux, polarization degree and polarization angle are calculated accounting for special and general relativistic effects. The calculations also extended to the case of nuclear-powered millisecond pulsars -- X-ray bursts. In this case, we consider one spot and the radiation is assumed to be produced in the atmosphere of the infinite Thomson optical depth. The light curves and polarization profiles show a large diversity depending on the model parameters. Presented results can be used as a first step to understand the observed pulse profiles of accretion- and nuclear-powered millisecond pulsars. Future observations of the X-ray polarization will provide a valuable tool to test the geometry of the emission region and its physical characteristics.

description: Although agriculture generates a significant portion of Australia’s greenhouse gas emissions, it also has the potential to sequester large quantities of emissions through changed land use management such as agroforestry. Whilst there is an extensive amount of agroforestry literature, little has been written on the economic consequences of adopting silvopastoral systems in northern Australia. This paper reports the economic feasibility of adopting complimentary agroforestry systems in the low rainfall region of northern Australia. The analysis incorporates the dynamic tradeoffs between tree and pasture growth, carbon sequestration, cleared regrowth decomposition rates and livestock methane emissions in a bioeconomic model. The results suggest there are financial benefits for landholders who integrate complimentary agroforestry activities into existing grazing operations depending on the rules of the carbon accounting framework used.

Soliton-induced absorption spectra for A_4_[Pt_2_(P_2_O_5_H_2_)_4_X]nH_2_O should split into two bands, while that for Pt_2_(RCS_2_)_4_I and Ni_2_(CH_3_CS_2_)_4_I should consist of a single band. The excitonic effect is significant in Ni_2_(CH_3_CS_2_)_4_I.

description: In the Mackay Whitsunday region, the dominant grazing based operations are small intensive systems that heavily utilise soil, nutrient and chemical management practices. To improve water quality entering the Great Barrier Reef, graziers are being encouraged to adopt improved management practices. However, while there is good understanding of the management changes required to reach improved practice classification levels, there is poor understanding of the likely economic implications for a grazier seeking to move from a lower level classification to the higher level classifications. This paper provides analysis of the costs and benefits associated with adoption of intensive grazing best management practices to determine the effect on the profitability and economic sustainability of grazing enterprises, and the economic viability of capital investment to achieve best management. The results indicate that financial incentives are likely to be required to encourage smaller graziers to invest in changing their management practices, while larger graziers may only require incentives to balance the risk involved with the transition to better management practices.

description: The oil palm boom in Southeast Asia has increased demand for institutional arrangements facilitating large-scale plantation development on customary lands. A financial model of an oil palm plantation in Sarawak, Malaysia, is used to explore six project types, including managed smallholders, three different joint-venture arrangements, renting, and (for comparison) a private plantation on state land. Benefit-cost analysis is used as basis for project, private (shareholder), and stakeholder analyses. There is a trade-off between the efficiency and equity outcomes of the alternative arrangements. While joint venture projects provide higher aggregate net benefits, managed smallholder projects provide more benefits to landholders. When the actual performance of the alternative schemes is taken into account, the managed smallholder approach is superior on both efficiency and equity grounds. The joint venture approach could be improved by combining a fixed rent with a share of dividends to reduce the income risk faced by landholders. In all cases, improved management is needed for the schemes to achieve their developmental potential.

description: With recent advances in supervised machine learning for medical image analysis applications, the annotated medical image datasets of various domains are being shared extensively. Given that the annotation labelling requires medical expertise, such labels should be applied to as many learning tasks as possible. However, the multi-modal nature of each annotated image renders it difficult to share the annotation label among diverse tasks. In this work, we provide an inductive transfer learning (ITL) approach to adopt the annotation label of the source domain datasets to tasks of the target domain datasets using Cycle-GAN based unsupervised domain adaptation (UDA). To evaluate the applicability of the ITL approach, we adopted the brain tissue annotation label on the source domain dataset of Magnetic Resonance Imaging (MRI) images to the task of brain tumor segmentation on the target domain dataset of MRI. The results confirm that the segmentation accuracy of brain tumor segmentation improved significantly. The proposed ITL approach can make significant contribution to the field of medical image analysis, as we develop a fundamental tool to improve and promote various tasks using medical images.
Moral sense and moral imperative : an analysis of the biological foundations of morality and their implications for moral theory
Creators: name: Woolley, Michaela Leigh
Publisher: name: University of British Columbia
Year: 2009

description: I argue that morality is in significant part a biological phenomenon, and that this has implications for substantive moral philosophy. I begin the first chapter by arguing for the hypothesis that human morality is on a continuum with conflict reducing behaviours that have been extensively documented in some non-human primate species. These behaviours provide evidence of the presence of moral building blocks such as sympathy, empathy, and a sense of social regularity. In the second chapter, I take up the objection that morality must be conceptually distinct from social behaviour evident elsewhere in the animal kingdom because altruism is an essential component of morality, and genuine altruism cannot evolve in nature. I argue that the concept of group selection can be used to demonstrate that there is indeed room for biological altruism in nature. In the third chapter, I explain how moral building blocks such as sympathy, empathy, and a sense of social regularity provide elements from which moral systems can be constructed. In the fourth chapter, I investigate the implications that the biological nature of morality has for substantive moral philosophy. Here I argue that some highly exigent moral demands are disconfirmed on the grounds that they are not supported by our experience of moral phenomena.

description: Pasture-cropping is a novel approach to increase the area of perennial crops in mixed sheep and cropping systems. It involves planting annual cereals directly into a living perennial pasture. There is interest in subtropical grasses as they are winter dormant and their growth profile is potentially well suited to pasture-cropping. However, a wide range of factors can affect the uptake of such systems. This paper assesses the relative importance of factors that can influence decisions to introduce pasture-cropping. In this paper the research question is: what factors predispose a farm to take up a new technology such as (1) subtropical grass and (2) subtropical grass that is pasture-cropped. The analysis uses the MIDAS model of a central wheatbelt farm in Western Australia. The results suggest the adoption of subtropical grasses is likely to be strongly influenced by soil mix; feed quality; and whether the farm is predominantly grazing or cropping and by the presence of meat versus wool producing animals. The same factors are relevant for subtropical grass that is pasture-cropped but in addition yield penalties due to competition between the host perennial and the companion cereal become important. The results suggest the level of forage production by subtropical grass is less important but this factor is likely to become more important if feed quality can be improved.

description: High-intensity laser fields acting on free electrons were proposed to create sufficiently large accelerations to enable detection of Unruh radiation. However, the currently achievable electron accelerations are not large enough. Here we demonstrate that Unruh effect in high-intensity laser fields is strongly enhanced near hyperbolic metamaterials, so that many orders of magnitude smaller accelerations may be used to detect Unruh radiation.

description: A water sharing plan is a legal document prepared under the Water Management Act 2000 (WMA) in New South Wales (NSW). It establishes the rules for sharing water between the environment and entitlement holders, with the goal of simultaneously protecting water dependant ecosystems and providing certainty for water users. In NSW 49 water sharing plans have commenced to date and another 40 plans are due to be commenced within next two years covering all surface and groundwater systems. The WMA requires that due consideration be given to the socio-economic impacts of the water sharing rules during preparation and mid-term reviews of the plans. This paper presents the framework used to undertake socio-economic assessment of the impacts of water sharing rules and a case study of impact assessment. The NSW Office of Water (the Office) has used a staged methodological framework that is consistent with the socio-economic assessment guidelines for river, groundwater and water management committees developed by the Independent Advisory Committee on Socio-economic Analysis (IACSEA 1998). This framework is simple, relevant and cost effective. The case study presents socio-economic impact assessment of water sharing rules of the Coopers Creek Water Sharing Plan that commenced in 2004. The results of the case study indicate that the proposed rules could have significant negative or positive impacts on regional irrigated production and employment. This shows that proposals for environmental gains may result in substantial economic losses to the irrigators.

description: The H0LiCOW collaboration inferred via gravitational lensing time delays a Hubble constant $H_0=73.3^{+1.7}_{-1.8}$ km s$^{-1}{\rm Mpc}^{-1}$, describing deflector mass density profiles by either a power-law or stars plus standard dark matter halos. The mass-sheet transform (MST) that leaves the lensing observables unchanged is considered the dominant source of residual uncertainty in $H_0$. We quantify any potential effect of the MST with flexible mass models that are maximally degenerate with H0. Our calculation is based on a new hierarchical approach in which the MST is only constrained by stellar kinematics. The approach is validated on hydrodynamically simulated lenses. We apply the method to the TDCOSMO sample of 7 lenses (6 from H0LiCOW) and measure $H_0=74.5^{+5.6}_{-6.1}$ km s$^{-1}{\rm Mpc}^{-1}$. In order to further constrain the deflector mass profiles, we then add imaging and spectroscopy for 33 strong gravitational lenses from the SLACS sample. For 9 of the SLAC lenses we use resolved kinematics to constrain the stellar anisotropy. From the joint analysis of the TDCOSMO+SLACS sample, we measure $H_0=67.4^{+4.1}_{-3.2}$ km s$^{-1}{\rm Mpc}^{-1}$, assuming that the TDCOSMO and SLACS galaxies are drawn from the same parent population. The blind H0LiCOW, TDCOSMO-only and TDCOSMO+SLACS analyses are in mutual statistical agreement. The TDCOSMO+SLACS analysis prefers marginally shallower mass profiles than H0LiCOW or TDCOSMO-only. While our new analysis does not statistically invalidate the mass profile assumptions by H0LiCOW, and thus their $H_0$ measurement relying on those, it demonstrates the importance of understanding the mass density profile of elliptical galaxies. The uncertainties on $H_0$ derived in this paper can be reduced by physical or observational priors on the form of the mass profile, or by additional data, chiefly spatially resolved kinematics of lens galaxies.

description: Developing predictive modeling in medicine requires additional features from unstructured clinical texts. In Russia, there are no instruments for natural language processing to cope with problems of medical records. This paper is devoted to a module of negation detection. The corpus-free machine learning method is based on gradient boosting classifier is used to detect whether a disease is denied, not mentioned or presented in the text. The detector classifies negations for five diseases and shows average F-score from 0.81 to 0.93. The benefits of negation detection have been demonstrated by predicting the presence of surgery for patients with the acute coronary syndrome.

description: If X is a smooth projective complex threefold, the Hodge conjecture holds for degree 4 rational Hodge classes on X. Kollar gave examples where it does not hold for integral Hodge classes of degree 4, that is integral Hodge classes need not be classes of algebraic 1-cycles with integral coefficients. We show however that the Hodge conjecture holds for integral Hodge classes of degree 4 on a uniruled or a Calabi-Yau threefold.

description: Interest has been growing in the nature of synergies in agroecosystems, prompted in part by growing concerns about the effects of environmental degradation on agricultural productivity and interrelations between agricultural outputs and ecosystem outputs. Most productivity analyses focus on technology, technical inefficiency and scale effects on productivity; yet scope economies derived from synergies can also have substantial effects that are likely to increase in the future. Scope economies take on special importance when farms diversify to halt declining biodiversity and other forms of environmental degradation. We present results of an empirical case study based on panel data on farms in England and Wales. A stochastic input distance function is estimated using Bayesian methods that enable economies of scope to be calculated between pairs of outputs based on the derivatives of the input distance function. Results confirm the presence of scope economies from diversity, providing prima facie evidence that diversity is beneficial in farming systems in England and Wales. But a number of challenges lie ahead to improve the data set and method of measuring scope economies for further substantiation of this evidence. Chief among them is the need to obtain a better measure of ecosystem outputs. The complexity of agroecosystems, with their diverse elements and numerous interactions between elements, presents a major challenge for data collection.

description: We propose a predictive building-up of tetrahedral molecules, based on a previously derived chirality index, which characterizes a tetrahedral molecule, with n chiral centers, as achiral, diastereoisomer, or enantiomer as a function of the observed inversions (at most one for each center) under rotation and superimposition to its mirror immage. The set of rules which is identified allows the classification of the new molecule, obtained by the addition of another chiral center, by the determination of the selection rule with respect to the added center.

description: Kinetic Monte Carlo simulation in conjunction with molecular dynamics simulation is utilized to study the effect of the steered deposition on the growth of Cu on Cu(1,1,17). It is found that the deposition flux becomes inhomogeneous in step train direction and the inhomogeneity depends on the deposition angle, when the deposition is made along that direction. Steering effect is found to always increase the growth instability, with respect to the case of homogeneous deposition. Further, the growth instability depends on the deposition angle and direction, showing minimum at a certain deposition angle off-normal to (001) terrace, and shows a strong correlation with the inhomogeneous deposition flux. The increase of the growth instability is ascribed to the strengthened step Erlich Schwoebel barrier effects that is caused by the enhanced deposition flux near descending step edge due to the steering effect.

description: Shock waves are examples of the far-from-equilibrium behaviour of matter; they are ubiquitous in nature, yet the underlying microscopic mechanisms behind their formation are not well understood. Here, we study the dynamics of dispersive quantum shock waves in a one-dimensional Bose gas, and show that the oscillatory train forming from a local density bump expanding into a uniform background is a result of quantum mechanical self-interference. The amplitude of oscillations, i.e., the interference contrast, decreases with the increase of both the temperature of the gas and the interaction strength due to the reduced phase coherence length. Furthermore, we show that vacuum and thermal fluctuations can significantly wash out the interference contrast, seen in the mean-field approaches, due to shot-to-shot fluctuations in the position of interference fringes around the mean.

description: This paper analyses the spatial pattern of the agricultural yield data. Using the spatial statistics, it is possible to estimate some parameters of the semivariogram to study the problem of the systemic risk, which has great implications for the crop insurance program in Brazil. In particular, the “range” parameter was estimated. This parameter measures the distance, in which the spatial correlation tends to zero. For the empirical analysis, county yield data was used provided by IBGE, for soybean and corn, in the state of Paraná, through 1990 and 2002. The results showed that there is spatial dependence in every year analysed, going to zero in relatively long distances (in km).

description: The paper discussed the main factors that explain the Brazilian agricultural exports. In order to achieve this goal, the paper applied a gravity model that includes fixed and random effects estimations, besides the Ordinary Least Squares (OLS) approach. Distance, trade partners´ GDP, and geographical localization were the significant variables. Moreover, puzzle effects are associated to exchange rate, partners´ agricultural exports profile and the partners´ agricultural share in GDP. Finally, this study highlights the potential change of the relevant variables because of specific characteristics of each commercial Brazilian partner.
