description: High frame rate videos are increasingly getting popular in recent years, driven by the strong requirements of the entertainment and streaming industries to provide high quality of experiences to consumers. To achieve the best trade-offs between the bandwidth requirements and video quality in terms of frame rate adaptation, it is imperative to understand the effects of frame rate on video quality. In this direction, we devise a novel statistical entropic differencing method based on a Generalized Gaussian Distribution model expressed in the spatial and temporal band-pass domains, which measures the difference in quality between reference and distorted videos. The proposed design is highly generalizable and can be employed when the reference and distorted sequences have different frame rates. Our proposed model correlates very well with subjective scores in the recently proposed LIVE-YT-HFR database and achieves state of the art performance when compared with existing methodologies.

description: We study the cohesive energy and elastic properties as well as normal modes of the Wigner and bubble crystals of the two-dimensional electron system (2DES) in higher Landau levels. Using a simple Hartree-Fock approach, we show that the shear moduli ($c_{66}$'s) of these electronic crystals show a non-monotonic behavior as a function of the partial filling factor $ν^*$ at any given Landau level, with $c_{66}$ increasing for small values of $ν^*$, before reaching a maximum at some intermediate filling factor $ν^*_m$, and monotonically decreasing for $ν^*>ν^*_m$. We also go beyond previous treatments, and study how the phase diagram and elastic properties of electron solids are changed by the effects of screening by electrons in lower Landau levels, and by a finite thickness of the experimental sample. The implications of these results on microwave resonance experiments are briefly discussed.

description: This paper provides an overview of concepts of sustainable agriculture and possible methods of attaining sustainability of agricultural yields and production. Reasons are given as to why modern industrialised agriculture might be less sustainable in terms of yields than traditional agriculture. The question of whether organic agriculture is likely to be more sustainable than non-organic agriculture is considered as well as organic agriculture’s likely impact on wild biodiversity. The impact of the development of agriculture on wild biodiversity is assessed because some environmentalists see the conservation of wild biodiversity as an important ingredient of sustainable development. However, there is a policy conflict between conservationist groups. Some see intensive agriculture (including silviculture) as favourable to the conservation of wild biodiversity whereas others oppose such production methods as being unfavourable to wild biodiversity conservation. Reasons why modern industrialised agricultural systems are so widely adopted (and continue to be adopted) despite their apparent lack of sustainability are suggested. Market systems may tend to lock producers into unsustainable production methods.

description: Non-perturbative corrections in text form
description: CERN-LHC. Measurement of the production cross section of events with two isolated photons in the final state, in proton-proton collisions at sqrt(s) = 7 TeV, by the ATLAS experiment at the LHC. The full data set collected in 2011, corresponding to an integrated luminosity of 4.9 fb^-1, is used. The amount of background, from hadronic jets and isolated electrons, is estimated with data-driven techniques and subtracted. The total cross section, for two isolated photons with transverse energies above 25 GeV and 22 GeV respectively, in the acceptance of the electromagnetic calorimeter (|eta| < 1.37 and 1.52 < |eta| < 2.37) and with an angular separation Delta(R) > 0.4, is 44.0 +3.2,-4.2 pb. The differential cross sections as a function of the di-photon invariant mass, transverse momentum, azimuthal separation, and cosine of the polar angle of the largest transverse energy photon in the Collins-Soper di-photon rest frame are also measured. NOTE: The cross section values reported in the table should be multiplied by a factor of 1.0141 to take into account the updated value of the integrated luminosity for the ATLAS 2011 data taking period. A relative uncertainty of 3.5% should be subtracted (in quadrature) from the total uncertainty to take into account the reduced value of the integrated luminosity uncertainty (1.8%) compared to the preliminary one used in the publication (3.9%). See Eur.Phys.J. C73 (2013) 2518 for more details. UPDATE 22 April 2016: Two files have been attached to document publicly the non-perturbative corrections used in the publication to compare the measurement to parton-level calculations.

Variations in the mean willingness to pay are analysed. Concerns arise about whether information provision and experience reveal ‘true’ contingent valuations of public goods and about the choice of the relevant contingent valuation measure.
A thermodynamically consistent theory of stress-gradient plasticity

Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: As an extension to strain-gradient models of size-dependent plastic behaviour, this work proposes a model for a stress-gradient theory. The model is distinguished from earlier works on the topic by its being embedded in a thermodynamically consistent framework. The development is carried out in the context of single-crystal plasticity, and draws on thermodynamically consistent models for single-crystal conventional and strain-gradient plasticity. The model is explored numerically using the example of torsion of a thin wire comprising a face centred cubic crystal, and its behaviour compared with that based on a recent disequilibrium density model of size-dependent plasticity.

description: We investigate the dynamics of non-interacting particles in a one-dimensional tight-binding chain in the presence of an electric field with random amplitude drawn from a Gaussian distribution, and explicitly focus on the nature of quantum transport. We derive an exact expression for the probability propagator and the mean-squared displacement in the clean limit and generalize it for the disordered case using the Liouville operator method. Our analysis reveals that in the presence a random static field, the system follows diffusive transport; however, an increase in the field strength causes a suppression in the transport and thus results in disorder-induced localization. We further extend the analysis for a time-dependent disordered electric field and show that the dynamics of mean-squared-displacement deviates from the parabolic path as the field strength increases, unlike the clean limit where ballistic transport occurs.

description: Using a species’ population to measure its conservation status, this note explores how an increase in knowledge about this status would change the public’s willingness to donate funds for its conservation. This is done on the basis that the relationship between the level of donations and a species’ conservation status satisfies stated general mathematical properties. This level of donation increases, on average, with greater knowledge of a species’ conservation status if it is endangered, but falls if it is secure. Game theory and other theory is used to show how exaggerating the degree of endangerment of a species can be counterproductive for conservation.
Non-Iterative Disentangled Unitary Coupled-Cluster based on Lie-algebraic structure

description: Due to their non-iterative nature, fixed Unitary Coupled-Cluster (UCC) ansätze are attractive for performing quantum chemistry Variational Quantum Eigensolver (VQE) computations as they avoid pre-circuit measurements on a quantum computer. However, achieving chemical accuracy for strongly correlated systems with UCC requires further inclusion of higher-order fermionic excitations beyond triples increasing circuit depth. We introduce $k$-NI-DUCC, a fixed and Non-iterative Disentangled Unitary Coupled-Cluster compact ansatz, based on specific $"k"$ sets of "qubit" excitations, eliminating the needs for fermionic-type excitations. These elements scale linearly ($\mathcal{O}(n)$) by leveraging Lie algebraic structures, with $n$ being the number of qubits. The key excitations are screened through specific selection criteria, including the enforcement of all symmetries, to ensure the construction of a robust set of generators. NI-DUCC employs $"k"$ products of the exponential of $\mathcal{O}(n)$- anti-Hermitian Pauli operators, where each operator has a length $p$. This results in a fewer two-qubit CNOT gates circuit, $\mathcal{O}(knp)$, suitable for hardware implementations. Tested on LiH, H$_6$ and BeH$_2$, NI-DUCC-VQE achieves both chemical accuracy and rapid convergence even for molecules deviating significantly from equilibrium. It is hardware-efficient, reaching the exact Full Configuration Interaction energy solution at specific layers, while reducing significantly the VQE optimization steps. While NI-DUCC-VQE effectively addresses the gradient measurement bottleneck of ADAPT-VQE-like iterative algorithms, the classical computational cost of constructing the $\mathcal{O}(n)$ set of excitations increases exponentially with the number of qubits. We provide a first implementation for constructing the generators' set able to handle up to 20 qubits and discuss the efficiency perspectives.

description: We consider the well-posedness and a priori error estimates of a 3d FEM-BEM coupling method for fluid-structure interaction in the time domain. For an elastic body immersed in a fluid, the exterior linear wave equation for the fluid is reduced to an integral equation on the boundary involving the Poincaré-Steklov operator. The resulting problem is solved using a Galerkin boundary element method in the time domain, coupled to a finite element method for the Lamé equation inside the elastic body. Based on ideas from the time-independent coupling formulation, we obtain an a priori error estimate and discuss the implementation of the proposed method. Numerical experiments illustrate the performance of our scheme for model problems.

description: Managing hawksbill turtle populations for use and conservation requires (i) adequate scientific understanding of their population status and dynamics and (ii) consideration of the public’s attitudes to this species. This study employs experimental surveys to assess the Australian public’s attitudes towards the hawksbill turtle, their knowledge of it, their views about its sustainable commercial harvesting, and their support and financial contribution for the species’ conservation. Contingent valuation reveals that the Australian public’s willingness to contribute to the conservation of the hawksbill turtle is high even in comparison to threatened Australian bird and mammal fauna. Most of this stated contribution is based on the intrinsic (non-use) value associated with the hawksbill turtle. It seems that the Australian public will only accept its harvesting if the sustainability of this is assured and its population is more secure. The CITES categorisation of the hawksbill as an Appendix I species hampers the development of techniques for its sustainable use.

description: This study contrasts the actual conservation spending and the Australian public’s demand for conservation funding for two Australian mammal species, the koala and the northern hairy-nosed wombat. It involves a survey of 204 members of the Australian public. Willingness to fund conservation action to protect the northern hairy-nosed wombat was found to be higher than that for the koala despite the koala’s immense popularity. The critically endangered status of the northern-hairy nosed wombat and the more secure conservation status of the koala is a factor likely to have influenced the comparative willingness-to-pay decisions. Actual annual conservation expenditure for both species is lower than the estimated aggregate willingness-to-pay for their conservation. Furthermore, conservation funding for the koala is much more than that for the northern hairy-nosed wombat even though the estimated public willingness-to-pay (demand) for funding koala conservation was less than for this wombat species. Reasons for this are suggested. They may also help to explain misalignment between demand for conservation funding of other species involving differences in charisma and endangerment.

description: Opinions differ about what types of policies are likely to be most effective in conserving wildlife species. For example, the Convention on International Trade in Endangered Species of Wild Flora and Fauna (CITES) is based on the premise that curbing the commercial use of endangered species favours their conservation, whereas the Convention on Biological Diversity envisages the possibility that such use may contribute to the conservation of species. In Australia, as illustrated in the case of the saltwater crocodile, the governments of the Northern Territory and Western Australia have favoured the latter policy in recent years whereas Queensland has favoured the former approach. The saltwater crocodile management plan of the Northern Territory provides an instructive case study of the consequences of adopting a commercial use strategy to promote wildlife conservation. The methodology used in this study, which involves a survey of crocodile farm managers and managers of cattle properties in the Northern Territory as well as secondary data, is outlined, after providing background on the conservation status of saltwater crocodiles in Australia and the saltwater crocodile management plan of the Northern Territory. In the results section, after outlining the nature and structure of the Northern Territory crocodile farming industry, evidence is presented on whether or not the crocodile management plan of the Northern Territory encourages pastoralists to conserve crocodiles on their properties. This study concludes with a discussion of the overall conservation effectiveness of the crocodile management scheme of the Northern Territory and considers its possible implications for saltwater crocodile management in areas of Asia where the species occurs.

description: We solve a long standing problem with relativistic calculations done with the widely used Multi-Configuration Dirac-Fock Method (MCDF). We show, using Relativistic Many-Body Perturbation Theory (RMBPT), how even for relatively high-$Z$, relaxation or correlation causes the non-relativistic limit of states of different total angular momentum but identical orbital angular momentum to have different energies. We show that only large scale calculations that include all single excitations, even those obeying the Brillouin's theorem have the correct limit. We reproduce very accurately recent high-precision measurements in F-like Ar, and turn then into precise test of QED. We obtain the correct non-relativistic limit not only for fine structure but also for level energies and show that RMBPT calculations are not immune to this problem.

description: Developments in narrative theory have seen a burgeoning of scholarly interest in the mimetic thickness of characters in fiction. Previously, structuralists were suspicious of the emotional involvement that comes with viewing characters as possible people, which may explain in part why character analysis in the practice of literary translation has been studied so seldom. My thesis seeks to address this gap, using Marie-Laurie Ryan’s ‘world model’ of characters. It seeks to argue that character analysis can be a powerful tool for translators of literary fiction. It can assist them to shape their translation strategy and define their translation choices. I argue as much through an approach that interweaves theoria and praxis. I devote half my thesis to a translation of Mónica Ojeda’s archival novel, La desfiguración Silva. In carrying out this translation, I mobilise character analysis in several ways: to formulate my preliminary translation strategy; to render voice; and to nuance other, genre-based decisions. In the process, I develop what I refer to throughout my critical commentary as an ethics of disfigurement, which recalls not only the source text through which this ethics was developed, but also Antoine Berman’s ‘textual deformation’. By way of this allusion, I cast disfigurement in a contrary posture, spotlighting the gains that works stand to accrue when they are recreated by other people in other cultures. My translation is full of deformations; it is also, if it has succeeded in what I set out to do, respectful of the work’s ‘shapeless polylogic’. Engaging with Gayatri Chakravorty Spivak’s translations and theories helped me envision this apparently paradoxical state as one I wished to strive for.Click here to download the critical commentary of this PhD thesis.
Stability of multibrane models

description: Multibrane 5-dimensional models with a warped extra spatial dimension compactified on an $S^1/\mathbb{Z}_2$ orbifold are investigated. The Goldberger-Wise field, with appropriate bulk and brane potentials, is utilized to fix the brane positions. However, not all configurations with fixed brane positions are stable. Stability against small scalar perturbations of the metric and the Goldberger-Wise field was so far analyzed only for 2-brane models. Generalization of such analysis for multibrane models is the main subject of the present work. Stability of brane configurations is closely related to the spectrum of radions: namely, the existence of any tachyonic radion indicates instability, while models with positive squared masses for all radions are stable. The necessary and sufficient conditions for each of these possibilities are derived for multibrane models and constitute the main result of this paper. Additionally, some properties of radions, particularly their relation to distances between and along branes, are discussed.

description: Attitudes of a sample of the Australian public towards the subsistence use of wildlife by indigenous Australians and whether or not indigenous Australians should be allowed to sell wildlife and wildlife products is examined. It has been suggested that allowing such possibilities would provide economic incentives for nature conservation among local people. We explore whether those sampled believe that indigenous Australians should do more than other groups and institutions to conserve Australia’s tropical species, and whether or not indigenous Australians should be allowed to take common as well as endangered wildlife species for food. Attitudes of the sampled public towards indigenous Australians earning income from trophy hunting and from the harvesting of northern long-necked turtles for the pet trade are canvassed. We find that the positive conservation consequences of sale of wildlife by indigenous Australians could be weak, although social justice suggests that they should not be denied this opportunity.

The data used in this study was collecty by interviewing fruit producers in the County of Aracti, Limoeiro do Norte e Quixeré. All the counties, after 1998 (the year of implantation of the Program) had improvement in technology use and increase in productivity. In most of the cases, an important benefit was the generation of local job opportunities. It is suggested that the Government should provide incentives in the form of credit, technical assistance and provide marketing guarantee and improved substructure to attract agricultural industries for better use of fruits in the states.

We find that the spin relaxation time for heavy holes can be comparable to or even longer than that for electrons in strongly two-dimensional quantum dots. We discuss the difference in the magnetic-field dependence of the spin relaxation rate due to Rashba or Dresselhaus spin-orbit coupling for systems with positive (i.e., GaAs quantum dots) or negative (i.e., InAs quantum dots) $g$-factor.

description: From 1997-2007, the United States Agency for International Development (USAID) Title II monetization programs sold more than US$200 million of food aid wheat and unrefined vegetable oils in Mozambique. This research has three objectives: 1) to document the lessons learned from past monetization programs in Mozambique; 2) to identify the intended and unintended effects of monetization in Mozambique; and 3) to document indirect successes as a result of using monetization in Mozambique, if any. Monetization programs in Mozambique prior to 1997 demonstrated positive effects on market development and contributed to food security in a critical period. During later periods, the monetized food aid displayed the negative effects of uncoordinated food aid deliveries and arrival of quantities beyond absorptive capacity, depressing prices for locally produced staples and adding to market price volatility.

description: This work evaluated the technical efficiency of productive resources utilization in small milk production farmers located in Viçosa region, Minas Gerais, Brazil. The study comprised small milk producers who have received technical assistance from a program created by the Federal University of Viçosa and Nestlé. The technical efficiency was evaluated using the Data Envelopment Analysis (DEA) technique. The results obtained show that there are some farmers efficient and others inefficient. It was also observed that, during the 1999-2003 period, the technical efficiency has improved in the most of the farmers analyzed.

description: Policies to promote demand-driven smallholder agriculture and improved urban food marketing system performance in Sub-Saharan Africa (SSA) need to be informed by careful food demand analysis, especially given the rapid rate of urbanization in many SSA countries. Governments, donors, and other policymakers require an up-to-date understanding of urban consumption patterns because these are among the main drivers of many of the opportunities available to small-scale farmers and because such information can help identify key leverage points to improve urban marketing system performance. It is also important to understand better the extent of, and constraints to, urban agriculture for household consumption as well as for cash income generation.

description: After two decades of de-urbanization, Zambia is again becoming increasingly urban. While the urban share of the population fell to 35% in 2000 due primarily to the decline of the copper industry, over half of Zambia’s people will be residing in urban areas by 2040. Given this urbanization trajectory, to be effective, policies to promote smallholder agriculture and improved urban food marketing system performance in Zambia will need to take into consideration the demand patterns of urban food consumers. Urban consumption patterns will increasingly determine the opportunities available to small-scale farmers. Accurate information on urban consumer preferences can also help identify key leverage points and investment priorities to improve the performance of the food marketing system.

description: This brief summarizes detailed analysis of the determinants of household crop income in rural Mozambique from 2002 to 2005. Increased crop income is associated with increases in household land area, use of animal traction, crop diversification into tobacco or cotton, access to market price information, and access to extension agents (for tobacco/cotton growers). Decreases in crop income are associated with drought. Results demonstrate that there are both public and private investments that can enhance farmers’ ability to increase crop income and avoid losses. Priority investments include: development and dissemination of drought-resistant varieties for maize and cassava, conservation farming, animal traction, market information, access to high-value crops and small-scale irrigation.
Polar and non-polar atomic motions in the relaxor ferroelectric PLZT from dielectric, anelastic and NMR relaxation

description: Dielectric, anelastic and ^139La NMR relaxation measurements have been made on the relaxor ferroelectric Pb(1-3x/2)La(x)Zr(0.2)Ti(0.8)O(3) (PLZT) with x = 0.22. The dielectric susceptibility exihibits the frequency dispersive maximum due to the freezing of the polar degrees of freedom around T ~250 K. The anelastic and especially NMR relaxation, besides this maximum, indicate an intense and broad component at lower temperatures, attributed to rotational modes of the O octahedra, weakly coupled to the polar modes. It is discussed why such short range rotational instabilities, known to occur in the Zr-rich rhombohedral region of the PLZT phase diagram, might appear also in the Ti-rich region.

description: Transient microstructure in the diffuse interstellar medium has been observed towards galactic and extragalactic sources for decades, usually in lines of atoms and ions, and, more recently, in molecular lines. Evidently, there is a molecular component to the transient microstructure. In this paper we explore the chemistry that may arise in such microstructure. We use a PDR code to model the conditions of relatively high density, low temperature, very low visual extinction and very short elapsed time that are appropriate for these objects. We find that there is a well defined region of parameter space where detectable abundances of molecular species might be found. The best matching models are those where the interstellar microstructure is young (<100 yr), small (~100 AU), and dense (>10^4 cm^-3).

description: • The Zambia Urban Consumption Survey, a survey of 1,865 urban households in Lusaka, Kitwe, Mansa, and Kasama, was conducted in August 2007 and February 2008 by the Central Statistical Office in collaboration with the Zambia Food Security Research Project. • Survey results indicate that in Lusaka and Kitwe, wheat has overtaken maize as the most important staple in terms of urban consumer expenditures. Maize is no longer the dominant staple food in urban Zambia, except among the poor. This finding is consistent with broader regional trends toward declining dependence on maize for urban staple food needs. • Hammer-milling services are readily available to the vast majority of urban households and in most cases their cheapest maize meal option is to obtain maize grain and have it custom-milled for a fee. However, maize grain is not consistently available in public markets during the lean season (December-March). GRZ could promote urban food security by ensuring that maize grain is available in public markets at all times. • In Kasama and Mansa, and particularly among relatively poor households, cassava is an important consumption item and serves as a buffer against high maize prices and poor maize grain availability during the lean season. • Supermarkets have only 5-17% of the market share for staple foods and are frequented mainly by wealthier households. Urban consumers are heavily dependent upon non-supermarket, informal retail outlets such as public markets and grocers for their staple food purchases. Policies and public investments to support these traditional retailers, help them operate more efficiently, and reduce the transaction costs they face may have higher payoffs for most urban consumers as well as smallholder farmers than policies presupposing the rapid takeover of supermarkets and other more formal retail channels.

description: The temperature dependence of resistivity, magnetization and electron-spin resonance of the $α- MnS $ single crystal were measured in temperature range of $5 K < T < 550 K$. Magnetization hysteresis in applied magnetic field up to 0.7 T at $T=5 K, 77 K, 300 K$, irreversible temperature behavior of magnetization and resistivity were found . The obtained data were explained in terms of degenerate tight binding model using random phase approximation. The contribution of holes in $t_{2g}$ and $e_g$ bands of manganese ions to the conductivity, optical absorbtion spectra and charge instability in $α-MnS $ were studied. Charge susceptibility maxima resulted from the competition of the on-site Coulomb interaction between the holes in different orbitals and small hybridization of sub-bands were calculated at $T=160 K, 250 K, 475 K$.
