description: While conventional Type Ia supernova (SN Ia) cosmology analyses rely primarily on rest-frame optical light curves to determine distances, SNe Ia are excellent standard candles in near-infrared (NIR) light, which is significantly less sensitive to dust extinction. A SN Ia spectral energy distribution (SED) model capable of fitting rest-frame NIR observations is necessary to fully leverage current and future SN Ia datasets from ground- and space-based telescopes including HST, LSST, JWST, and RST. We construct a hierarchical Bayesian model for SN Ia SEDs, continuous over time and wavelength, from the optical to NIR ($B$ through $H$, or $0.35 -1.8\, μ$m). We model the SED as a combination of physically-distinct host galaxy dust and intrinsic spectral components. The distribution of intrinsic SEDs over time and wavelength is modelled with probabilistic functional principal components and the covariance of residual functions. We train the model on a nearby sample of 79 SNe Ia with joint optical and NIR light curves by sampling the global posterior distribution over dust and intrinsic latent variables, SED components, and population hyperparameters. The photometric distances of SNe Ia with NIR data near maximum light obtain a total RMS error of 0.10 mag with our BayeSN model, compared to 0.14 mag with SNooPy and SALT2 for the same sample. Jointly fitting the optical and NIR data of the full sample for a global host dust law, we find $R_V = 2.9 \pm 0.2$, consistent with the Milky Way average.

We point out some new contributions in the form of bilinear-trilinear combination of R-parity violating (RPV) couplings that are enhanced by large tanbeta. We also improve by a few orders of magnitude, bounds on several combinations of R-parity violating parameters.

description: Lippia origanoides Kunth is a perennial shrub widely used in Brazilian folk medicine while extracts of its leaves have been shown to possess several therapeutic properties. We investigated this species’ non-volatile compounds through a LC-MS-based untargeted metabolomics approach to evaluate the influence of genetic and developmental factors on L. origanoides metabolism. We compared five adult plants and eight leaf developmental stages separately; the chemical analyses were performed via UHPLC-ESI-QTOF-MS/MS and the resulting data were processed in Progenesis QI 2.0 and in MetaboAnalyst 6.0 for statistical analysis. Luteolin-7-O-glucoside and kaempferol/luteolin were the most intense components in the negative and positive ion modes, respectively. A subtle chemical variation between individuals was found while the leaf development, conversely, strongly affected the chemical profile, which may ultimately result in variation in bioactivity. Altogether, we reported herein new perspectives on L. origanoides non-volatile components and the impact of intraspecific factors on this species’ metabolism.

description: We explicitly measure corn acreage response to the biofuels boom from 2006 to 2010. Specifically, we use newly available micro-scale planting data over time to test whether corn cultivation intensifies in proportion to the proximity of ethanol processors. We control for the endogeneity of plant location to corn acreage by using transportation network data for instruments. Our results show that reducing the distance between a farm and an ethanol plant by one percent increases acreage in corn by 0.64% and reveal a price elasticity of supply of 0.47%. To our knowledge, this is the first study that measures changes in location and intensity of corn planting in response to incentives posed by the recent biofuels boom. The results can serve as a springboard for researchers and policy-makers concerned with crop diversity, environmental sustainability, and greenhouse gas emissions.

Towards control of opinion diversity by introducing zealots into a polarised social group

description: We explore a method to influence or even control the diversity of opinions within a polarised social group. We leverage the voter model in which users hold binary opinions and repeatedly update their beliefs based on others they connect with. Stubborn agents who never change their minds ("zealots") are also disseminated through the network, which is modelled by a connected graph. Building on earlier results, we provide a closed-form expression for the average opinion of the group at equilibrium. This leads us to a strategy to inject zealots into a polarised network in order to shift the average opinion towards any target value. We account for the possible presence of a backfire effect, which may lead the group to react negatively and reinforce its level of polarisation in response. Our results are supported by numerical experiments on synthetic data.

description: Manipulating single surface atoms and adsorbates opens the possibility of structuring surfaces with atomic precision. This requires the use of a Low- Temperature Scanning Tunneling Microscope (LT-STM), which was assembled in this work. Atomic resolution data were obtained of closed packed metal surfaces at 18K and standing wave patterns observed on Cu(lll). Manipulation experiments with CO on Cu lll) were carried out to test the capabilities of the new instrument. In the course of this experiments the most recent imaging theory could be tested and the manipulation parameters of CO on Cu(lll) optimized.

description: Due to their unique properties as lossless, nonlinear circuit elements, Josephson junctions lie at the heart of superconducting quantum information processing. Previously, we demonstrated a two-layer, submicrometer-scale overlap junction fabrication process suitable for qubits with long coherence times. Here, we extend the overlap junction fabrication process to micrometer-scale junctions. This allows us to fabricate other superconducting quantum devices. For example, we demonstrate an overlap-junction-based Josephson parametric amplifier that uses only 2 layers. This efficient fabrication process yields frequency-tunable devices with negligible insertion loss and a gain of ~ 30 dB. Compared to other processes, the overlap junction allows for fabrication with minimal infrastructure, high yield, and state-of-the-art device performance.

Floquet scattering theory for current and heat noise in large amplitude adiabatic pumps

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: We discuss the statistical correlation properties of currents and energy flows generated by an adiabatic quantum pump. Our approach emphasizes the important role of quantized energy exchange between the sea of electrons and the oscillating scatterer. The pump-frequency introduces a natural energy scale. In the low temperature limit, thermal energy much smaller than a modulation quantum, the pump generates a shot-like noise which manifests itself in photon-assisted quantum mechanical exchange amplitudes. In the high temperature limit, thermal energy much larger than a modulation quantum, the pump producesa thermal-like noise due to ac-currents generated by the pump. We predict that with increasing temperature the frequency dependence of the noise changes. The current noise is linear in pump-frequency at low temperatures, is quadratic at intermediate temperatures, and is linear again at high temperatures. Similarly, in the same temperature regions, the heat flow noise is proportional to the third, second and first power of the pump-frequency.

description: We perform a systematic study of the ground-state properties of all the nuclei from the proton drip line to the neutron drip line throughout the periodic table employing the relativistic mean field model. The TMA parameter set is used for the mean-field Lagrangian density, and a state-dependent BCS method is adopted to describe the pairing correlation. The ground-state properties of a total of 6969 nuclei with $Z,N\ge 8$ and $Z\le 100$ from the proton drip line to the neutron drip line, including the binding energies, the separation energies, the deformations, and the rms charge radii, are calculated and compared with existing experimental data and those of the FRDM and HFB-2 mass formulae. This study provides the first complete picture of the current status of the descriptions of nuclear ground-state properties in the relativistic mean field model. The deviations from existing experimental data indicate either that new degrees of freedom are needed, such as triaxial deformations, or that serious effort is needed to improve the current formulation of the relativistic mean field model.

description: The young PSR B0540-69 (B0540) in the LMC is the only pulsar (except the Crab pulsar) for which a near-UV spectrum has been obtained. However, the absolute flux and spectral index of previously published HST/FOS data are significantly higher than suggested by broadband groundbased UBVRI photometry. Using our ESO/VLT/FORS1 spectral observations and HST/WFPC2 archival images we show that the old HST and new VLT spectral data are >50% contaminated by the Pulsar Wind Nebula (PWN) and that this is the reason for the above mentioned difference. We find that the broadband HST spectrum for the range 3300-8000 A is clearly non- thermal and has a negative spectral index of 1.07(+0.20/-0.19). This is dif- ferent from the almost flat spectrum of the Crab pulsar. The PWN of B0540 shows a clear asymmetry of the surface brightness distribution along the major axis of the PWN torus-like structure with respect to the pulsar position, also seen in Chandra X-ray images. This can be linked to the asymmetry of the surrounding SN ejecta. We find no significant spectral index variation over the PWN. Using HST archival images we estimate the proper motion of B0540 to be 4.9+/-2.3 mas/yr, i.e. a transverse velocity of 1190+/-560 km/s along the southern jet of the PWN. This can make PSR B0540 the third pulsar with a proper motion aligned with the jet axis of its PWN, which poses constraints on pulsar kick models. We discuss the interstellar absorption toward B0540 including the contributions from the Milky Way, LMC and the supernova ejecta, and compare unabsorbed multi- wavelength spectra of B0540 and the Crab pulsar, and their PWNs. Compared with the Crab, B0540 and its PWN show a significant depression in the optical range.

Portfolio losses are computed under the old and new SRA rules and regulations for comparison purposes.

description: The influence of surface tension and size on rounding of cell aggregates are studied using chick embryonic cells and numerical simulations based on the cellular Potts model. Our results show exponential relaxation in both cases as verified in previous studies using 2D Hydra cell aggregates. The relaxation time decreases with higher surface tension as expected from hydrodynamics laws. However, it increases faster than linearly with aggregate size. The results provide an additional support to the validity of the cellular Potts model for non-equilibrium situations and indicate that aggregate shape relaxation is not governed by the hydrodynamics of viscous liquids.
Solvability and PT-symmetry in a double-well model with point interactions

description: We show that and how point interactions offer one of the most suitable guides towards a quantitative analysis of properties of certain specific non-Hermitian (usually called PT-symmetric) quantum-mechanical systems. A double-well model is chosen, an easy solvability of which clarifies the mechanisms of the unavoided level crossing and of the spontaneous PT-symmetry breaking. The latter phenomenon takes place at a certain natural boundary of the domain of the "acceptable" parameters of the model. Within this domain the model mediates a nice and compact explicit illustration of the not entirely standard probabilistic interpretation of the physical bound states in the very recently developed (so called PT symmetric or, in an alternative terminology, pseudo-Hermitian) new, fairly exciting and very quickly developing branch of Quantum Mechanics.

description: We extend the existing literature on food taxes targeting obesity. First, we incorporate the implicit substitution between sugar and fat nutrients implied by a complete food demand system and by conditioning on how food taxes affect total calorie intake. Second, we propose a methodology that accounts for the ability of consumers to substitute leaner low-fat and low-sugar items for rich food items within the same food group. This substitution is integrated into a demand system in addition to substitution among food groups. Simulations of a tax on added sugars show that the impact of the tax on consumption patterns is understated and the effect on welfare loss overstated when abstracting from this substitution within food groups.

description: We have performed a comparative study of rubrene single-crystal field-effect transistors fabricated using different materials as gate insulator. For all materials, highly reproducible device characteristics are obtained. The achieved reproducibility permits to observe that the mobility of the charge carriers systematically decreases with increasing the dielectric constant of the gate insulator, the decrease being proportional to (epsilon)-1. This finding demonstrates that the mobility of carriers in organic single-crystal field-effect transistors is an intrinsic property of the crystal/dielectric interface and that it does not only depend on the specific molecule used.

description: In processing industries, plant location decisions are costly and have consequences for firm profitability. When raw materials are heavy or perishable, transportation costs limit shipping distances and processors must compete locally for raw material inputs. To determine the likely profitability of a new plant, a processor must forecast the effect entry will have on local post-entry raw material price. This requires anticipating how entry will affect market structure and intensify competition for raw materials. Using an econometric representation of game-theoretic Nash equilibria relating input prices to processor competition in local procurement areas, an empirical model is developed to ex ante forecast the likely impact of entry on input price. The methods developed are applicable to a wide variety of industries where historic data are available.

description: Invasive species are significant threats to biodiversity, natural ecosystems and agriculture leading to large worldwide economic and environmental damage. Spread and control of invasive species are stochastic processes with important spatial dimensions. Most economic studies of invasive species control ignore spatial and stochastic aspects. This paper covers this gap in the previous studies by analysing a spatially explicit dynamic process of controlling invasive species in a stochastic setting. We show how stochasticity, spatial location of infestation and control can influence the spread, control efficiency and optimal control strategies. The main aim of this paper is to analyse the relationship between economic parameters and stochastic spatial characteristics of infestation and control. In the model used, there are two ways to control infestation: border control, under which the spread of invasive species from any of its infested neighbouring cell is prevented, and cell control, which removes the infestation from the existing cell. An integer optimisation model is applied to find the optimal strategies to deal with invasive species. Results show that it is optimal to eradicate or contain for a larger range of border control and cell control costs when the invasion is in the corner or on the edge as compared to the case where the initial infestation is in the middle of the landscape. Decrease in the probability of successful border control makes containment an unfavourable control option even for low border control costs. We show that decrease in the rate of spread can result in switching optimal strategies from containment to abandonment of control, or from eradication to containment. We also showed when the probability of successful cell control decreases, a lower eradication cost is required for eradication to remain the optimal strategy. In summary, this paper shows that in order to avoid providing misleading recommendations to environmental managers, it is important to include uncertainty in the spatial dynamic analysis of invasive species control.

description: Using a sequence of decennial farm censuses, we examine Brazil’s agricultural performance over the last several decades as the economy shifted slowly from a producer-protected to liberalized environment. Those shifts provide the data for investigating Brazilian policy’s implications for agricultural competitiveness and efficiency. We decompose mean-farm total factor productivity into frontier productivity and efficiency change, each of the two influenced independently by government policy. National technology growth is found to have been an exceptionally high 4.5% per annum. Because, however, average farms were unable to keep pace with it, TFP growth has been a much smaller 2.6% per year. Although frontier producers in the south have outperformed their northern counterparts, TFP growth in the south has been lower than in the north. Benefits from Brazil’s agricultural research system have been tilted toward the farming sector's technological leaders, widening the productivity gap between frontier and average producer. Credit, education, and road construction policies have instead narrowed that gap.

description: We analyse the experimental particle current auto correlation function (CAF) of suspensions of hard spheres. Interactions between the particles are mediated by thermally activated acoustic excitations in the solvent. Those acoustic modes are tantamount to the system's (energy) microstates and by their orthogonality, each of those modes can be identified with an independent Brownian particle current. Accordingly, partitioning of the system's energy states is impressed on the CAF. This impression provides a novel measure of the entropy and location of a partitioning/entropy limit at a packing fraction that coincides with that of the observed suspension's first order freezing transition.

description: The real-space multiple-scattering (RSMS) approach is applied to model non-resonant inelastic scattering from deep core electron levels over a broad energy spectrum. This approach is applicable to aperiodic or periodic systems alike and incorporates ab initio, self-consistent electronic structure and final state effects. The approach generalizes to finite momentum transfer a method used extensively to model x-ray absorption spectra (XAS), and includes both near edge spectra and extended fine structure. The calculations can be used to analyze experimental results of inelastic scattering from core-electrons using either x-ray photons (NRIXS) or electrons (EELS). In the low momentum transfer region (the dipole limit), these inelastic loss spectra are proportional to those from XAS. Thus their analysis can provide similar information about the electronic and structural properties of a system. Results for finite momentum transfer yield additional information concerning monopole, quadrupole, and higher couplings. Our results are compared both with experiment and with other theoretical calculations.

Inspired by the scheme put forward by Gottesman, Kitaev, and Preskill for encoding a qubit in an oscillator, in which Clifford operations may be performed via Gaussian unitaries, this approach yields new schemes for encoding a qubit in a large spin in which single-qubit Clifford operations may be performed via spatial rotations. I construct all possible examples of such codes, provide universal-gate-set implementations using Hamiltonians that are at most quadratic in angular-momentum operators, and derive criteria for when these codes exactly correct physically relevant noise channels to lowest order, illustrating their performance numerically for specific low-dimensional examples.

description: This study examines the impact of adopting Bt corn on farm profits, yields, and insecticide use. The study employs an econometric model that corrects for self-selection and simultaneity. The model is estimated using nationwide farm-level survey data for 2005. Regression analysis confirms that Bt adoption is associated with increased profits, yields and seeding rates. However, the results of this analysis suggest that Bt adoption is not significantly related to insecticide use. This result appears to be related to the fact that insect infestation levels were lower in 2005 than they were in earlier years.
Debating an ideal federal arrangement for the European Union : a comparative analysis of Switzerland, Canada and the European Union
Creators: name: Babczak, Robert
Publisher: name: University of British Columbia
Year: 2009

description: There are few who would deny the overwhelming and already existing federal elements in the European Union (EU). The EU's growing responsibilities supported by the Treaty of Maastricht and the newly proposed EU Constitutional Treaty are clear evidence of this. The challenges of managing an enlarged and a more diverse EU will require new arrangements to achieve the 'ever-closer union'. These arrangements will need a federal model in order to maintain the already existing quasi-federal EU. The federal model, as distinct from the unitary nation-state, can offer possible solutions to remedying such EU dilemmas as: the legitimacy of the EU institutions, the capacity for decision-making, the democratic deficit and the accommodation of territorial and cultural distinctiveness of member states. The research focuses on comparative analysis and works toward explaining the rationale behind the federal model for the European Union. The study presents the historical background and the theory behind ideas of federalism in Europe. It evaluates existing federal arrangements showcasing the examples of Canada and Switzerland. On the basis of a five point federal test, which serves as a comparative tool, this study suggests that federalism is the relevant model for the European Union. Moreover, the paper proposes that the federal model, due to its strict definition, can benefit the EU's multi-level governance and reinforce the legitimacy of already existing EU treaties. The process of EU integration, though an ongoing political and economic experiment, must look for viable sources of reliable and valuable past experiences. In search for the most suitable federal model for the EU, the comparative experience of Swiss and Canadian federations allow us to identify similarities and differences, successes and failures, as well as provide mechanisms and processes which may help to deal with any future problems of EU integration.

description: Heterogeneous processors, formed by binary compatible CPU cores with different microarchitectures, enable energy reductions by better matching processing capabilities and software application requirements. This new hardware platform requires novel techniques to manage power and energy to fully utilize its capabilities, particularly regarding the mapping of workloads to appropriate cores. In this paper we validate relevant published work related to power modelling for heterogeneous systems and propose a new approach for developing run-time power models that uses a hybrid set of physical predictors, performance events and CPU state information. We demonstrate the accuracy of this approach compared with the state-of-the-art and its applicability to energy aware scheduling. Our results are obtained on a commercially available platform built around the Samsung Exynos 5 Octa SoC, which features the ARM big.LITTLE heterogeneous architecture.

description: A pair of surgeries on a knot is called purely cosmetic if the pair of resulting 3-manifolds are homeomorphic as oriented manifolds. Using recent work of Hanselman, we show that (nontrivial) knots which arise as the closure of a 3-stranded braid do not admit any purely cosmetic surgeries.

description: O objetivo da pesquisa foi analisar o processo de desconcentração e interiorização da economia do estado do rio de Janeiro na última década, mais especificamente o período de 1996 a 2005. Com o uso do modelo estrutural diferencial, fez-se uma análise da evolução do pessoal ocupado nas diversas mesorregiões geográficas que compõem o estado, considerandose as atividades: indústria extrativa mineral, indústria de transformação, serviços industriais de utilidade pública, indústria da construção civil, comércio, serviços, administração pública e agropecuária. Os resultados evidenciaram a ocorrência de desconcentração industrial, com redução da participação da região metropolitana no emprego e na renda, o que se deve, principalmente, à expansão da indústria extrativa mineral associada ao petróleo.------------the Rio de Janeiro's economy, during the last decade (from 1996 to 2005). It was considered the empolyment in the activities: mineral extraction industry, manufacturing industry, industrial utility services, construction industry, trade, services, public administration and farming. The employment evolution, by regions of Rio de Janeiro, was studied with the shiftshare analysis. By the results, Rio de Janeiro's economy became less concentrated, reducing the participation of the metropolitan region in the job and the income. The growth of the mineral extraction industry, associate to the oil, is one of the main causes of these changes.

description: With the increasing demand for video content at higher resolutions, it is evermore critical to find ways to limit the complexity of video encoding tasks in order to reduce costs, power consumption and environmental impact of video services. In the last few years, algorithms based on Neural Networks (NN) have been shown to benefit many conventional video coding modules. But while such techniques can considerably improve the compression efficiency, they usually are very computationally intensive. It is highly beneficial to simplify models learnt by NN so that meaningful insights can be exploited with the goal of deriving less complex solutions. This paper presents two ways to derive simplified intra-prediction from learnt models, and shows that these streamlined techniques can lead to efficient compression solutions.
