description: The operations of the Canadian Wheat Board (CWB), a state trading enterprise, have generated controversy over the years, partly because of an alleged lack of transparency in its operations. This study examines one aspect of operations that is not well understood - the government guarantee of CWB borrowing and export credit sales. The CWB is able to take advantage of this special privilege to generate a "financial cushion," or non-market based revenue, that it can use to enhance returns to producers, discount export prices, or pay administrative expenses. Current WTO negotiations should build on U.S. and EU proposals on STEs and export credit guarantees to address potential trade-distorting practices of STEs such as the CWB.

description: We present a comprehensive optical study of the narrow gap $FeSb_2$ semiconductor. From the optical reflectivity, measured from the far infrared up to the ultraviolet spectral range, we extract the complete absorption spectrum, represented by the real part $σ_1(ω)$ of the complex optical conductivity. With decreasing temperature below 80 K, we find a progressive depletion of $σ_1(ω)$ below $E_g\sim 280$ cm$^{-1}$, the semiconducting optical gap. The suppressed (Drude) spectral weight within the gap is transferred at energies $ω>E_g$ and also partially piles up over a continuum of excitations extending in the spectral range between zero and $E_g$. Moreover, the interaction of one phonon mode with this continuum leads to an asymmetric phonon shape. Even though several analogies between $FeSb_2$ and $FeSi$ were claimed and a Kondo-insulator scenario was also invoked for both systems, our data on $FeSb_2$ differ in several aspects from those of $FeSi$. The relevance of our findings with respect to the Kondo insulator description will be addressed.

description: Until recently, it is hard to find studies to estimate how much the total economic losses for U.S. or other states by the BSE incidents except one dominant study by Devadoss et al (2005), which used CGE (Computable Generalized Equations) model for U.S. However, they are not reporting the direct impacts by each state and indirect impacts resulting from state-by-state economic relations. The interindustry relations and spatial connections have required to developing the Multiregional Input-Output (MRIO) type model, and in the sense, the experience of beef export closures to foreign countries is the suitable case enabling to estimate the economic impacts via inter-regional inter-industrial connections. Therefore, this study estimated the U.S. economic losses by foreign export closures of each state due to the BSE incident in Washington State using a different, newly developed methodology, complementing the previous study. To assess the economic impacts of BSE on each state and U.S. national economy, we used two methodologies. First, we forecasted normal status of beef exports from January in 2004 to April in 2005 using time-series analyses, based on monthly pre-2004 foreign historical exports data obtained from WISERTrade data, in order to calculate the direct gaps between the estimated exports which would have been had if the BSE had not been discovered and the actually decreased exports. Second, a newly constructed MRIO-type model by Park et al (2006), the NIEMO (National Interstate Economic Model), addressed how much the impacts within each state including Washington, interstate effects, and U.S. national losses by the BSE are, based on the final demand losses from the ex-post incidents. While domestic U.S. market can find the equilibrium rapidly by tightening supply side, international barriers to hinder U.S. exports still become a critical agricultural policy for U.S. government. The closure of U.S. exports of bovine by mad cow disease occurred in Washington State yielded a huge shock into the U.S. economy due to simultaneous closures of other state exports. Currently, the only available MRIO model, the NIEMO, enables to estimate the economic losses by the simultaneous closures of each state export of beef and related products. In terms that the NIEMO can supply information comparing the different economic impacts of state-by-state to agricultural policy-makers, they can distribute the national subsides due to the incident, considering the spreading impacts.

description: We report on the results of a measurement study carried out on a commuter bus in Dublin, Ireland using the Google/Apple Exposure Notification (GAEN) API. This API is likely to be widely used by Covid-19 contact tracing apps. Measurements were collected between 60 pairs of handset locations and are publicly available. We find that the attenuation level reported by the GAEN API need not increase with distance between handsets, consistent with there being a complex radio environment inside a bus caused by the metal-rich environment. Changing the people holding a pair of handsets, with the location of the handsets otherwise remaining unchanged, can cause variations of +/-10dB in the attenuation level reported by the GAEN API. Applying the rule used by the Swiss Covid-19 contact tracing app to trigger an exposure notification to our bus measurements we find that no exposure notifications would have been triggered despite the fact that all pairs of handsets were within 2m of one another for at least 15 mins. Applying an alternative threshold-based exposure notification rule can somewhat improve performance to a detection rate of 5% when an exposure duration threshold of 15 minutes is used, increasing to 8% when the exposure duration threshold is reduced to 10 mins. Stratifying the data by distance between pairs of handsets indicates that there is only a weak dependence of detection rate on distance.

description: The paper develops a theoretical framework of heterogeneous consumers and producers to examine the market and welfare effects of the introduction of variety-level genetic use restriction technologies (V-GURTs) under the current No-Labeling regime of GMPs in the US market. Specifically, the study examines how the agronomic characteristics of GURTs, consumer perceptions and preferences regarding interventions in the production process (i.e., genetic modification) and producer cost structures (e.g., dependency on saving seed) affect the adoption of the technology by producers, the market acceptance of GURTs by consumers and consequently the innovator's incentive to introduce the new technology. Analytical results show that the introduction of GURTs may be welfare enhancing for consumers, producers and innovating firms when consumer aversion to GURTs is low, the agronomic benefits of the GURTs crop are high, and the expected penalty producers face when they cheat on their GM licensing agreements (e.g., due to inefficient or costly monitoring)is low.

description: The article presents a dynamic model of research investment. This model allows us to examine three important channels through which public investment policy can affect the private sector's research investment, that is, the productivity, replacement, and wage effects. Two alternative empirical approaches are introduced to implement the model. Through a unified examination of the productivity, replacement, and wage effects, the empirical estimation of this model will provide insight into whether public-sector research investment crowds in or crowds out private-sector research investment.

description: The abundance of α-elements provides an important fossil signature in Galactic archaeology to trace the chemical evolution of the different disc populations. High-precision chemical abundances are crucial to improving our understanding of the chemodynamical properties present in the Galaxy. However, deriving precise abundance estimations in the metal-rich disc ([M/H] > 0 dex) is still challenging. The aim of this paper is to analyse different error sources affecting magnesium abundance estimations from optical spectra of metal-rich stars. We derived Mg abundances for 87522 high-resolution spectra of 2210 solar neighbourhood stars from the AMBRE Project. For this purpose, the GAUGUIN automated abundance estimation procedure was employed. The normalisation procedure has a strong impact on the derived abundances, with a clear dependence on the stellar type and the line intensity. For non-saturated lines, the optimal wavelength domain for the local continuum placement should be evaluated using a goodness-of-fit criterion, allowing mask-size dependence with the spectral type. Moreover, for strong saturated lines, applying a narrow normalisation window reduces the parameter-dependent biases of the abundance estimate, increasing the line-to-line abundance precision. In addition, working at large spectral resolutions always leads to better results than at lower ones. The resulting improvement in the abundance precision makes it possible to observe both a clear thin-thick disc chemical distinction and a decreasing trend in the magnesium abundance even at supersolar metallicities. In the era of precise kinematical and dynamical data, optimising the normalisation procedures implemented for large spectroscopic stellar surveys would provide a significant improvement to our understanding of the chemodynamical patterns of Galactic populations.

Statistical model for filamentary structures of molecular clouds -- The modified multiplicative random cascade model and its multifractal nature

description: We propose a new statistical model that can reproduce the hierarchical nature of the ubiquitous filamentary structures of molecular clouds. This model is based on the multiplicative random cascade, which is designed to replicate the multifractal nature of intermittency in developed turbulence. We present a modified version of the multiplicative process where the spatial fluctuations as a function of scales are produced with the wavelet transforms of a fractional Brownian motion realisation. This simple approach produces naturally a log-normal distribution function and hierarchical coherent structures. Despite the highly contrasted aspect of these coherent structures against a smoother background, their Fourier power spectrum can be fitted by a single power law. As reported in previous works using the multiscale non-Gaussian segmentation (MnGSeg) technique, it is proven that the fit of a single power law reflects the inability of the Fourier power spectrum to detect the progressive non-Gaussian contributions that are at the origin of these structures across the inertial range of the power spectrum. The mutifractal nature of these coherent structures is discussed, and an extension of the MnGSeg technique is proposed to calculate the multifractal spectrum that is associated with them. Using directional wavelets, we show that filamentary structures can easily be produced without changing the general shape of the power spectrum. The cumulative effect of random multiplicative sequences succeeds in producing the general aspect of filamentary structures similar to those associated with star-forming regions. The filamentary structures are formed through the product of a large number of random-phase linear waves at different spatial wavelengths. Dynamically, this effect might be associated with the collection of compressive processes that occur in the interstellar medium.

description: We consider noisy, non-local unitary operations or interactions, i.e. the corresponding evolutions are described by completely positive maps or master equations of Lindblad form. We show that by random local operations the completely positive maps can be depolarized to a standard form with a reduced number of parameters describing the noise process in such a way that the noiseless (unitary) part of the evolution is not altered. A further reduction of the parameters, in many cases even to a single one (i.e. global white noise), is possible by tailoring the decoherence process and increasing the amount of noise. We generalize these results to the dynamical case where the ideal unitary operation is given by some interaction Hamiltonian. The resulting standard forms may be used to compute lower bounds on channel capacities, to simplify quantum process tomography or to derive error thresholds for entanglement purification and quantum computation.

Mould taper, heat transfer and spray cooling in high speed continuous casting
Creators: name: Fu, Junlong
Publisher: name: University of British Columbia
Year: 2009

description: Competition around the world and market expectations are driving the steel industry to improve billet quality and lower costs by increasing casting speed of continuous casters. The demand for high casting speeds can be achieved by increasing mould length and by making upgrades to the secondary cooling system. A plant trial was conducted at Co- Steel Lasco for the purpose of assessing the performance of a 1016 mm long mould having a parabolic taper on the high speed casting of 6 grades of steel billets. The mould was instrumented with 52 thermocouples. The billet section size was 178x127 mm, cast at speeds in the range of 2.2-2.9 m/min. Additionally, three linear variable displacement transducers were installed on the mould wall to monitor the mould oscillation. Billet samples were collected for several operating conditions. An inverse heat conduction model was used to calculate mould heat fluxes from measured mould wall temperatures. Existing mathematical models were employed to investigate mould-billet interaction and the adequacy of the mould taper. It was shown that steel carbon content and casting speed had significant effects on heat flux in the mould. Heat flux was highest for medium carbon steel followed by high carbon steel; low carbon steel had the least amount of heat transfer. Increases in casting speed consistently led to heat flux increases, although not proportionately. Off-corner internal cracks and narrow face concavity were noted on all billet samples. It was demonstrated that the taper was too tight for the low carbon grades which caused squeezing of the shell by the mould and was responsible for the off-corner internal cracks and the narrow face concavity of the billets. For the medium and high carbon billets the mould taper was inadequate especially in the lower part of the mould. Here, it was likely that bulging of the broad face and corner rotation gave rise to longitudinal depressions on the narrow face and off-corner internal cracks. Optimum tapers were recommended respectively for low carbon, medium carbon and high carbon steels. Spray cooling systems for three companies were also investigated. Billet surface temperature was calculated with a mathematical model; the effect of surface reheating between mould and spray cooling, between different spray cooling zones and between spray cooling and radiation as well as the billet liquid pool depth were examined It was shown that midway cracks can result from the billet surface reheating in the secondary cooling zone. Additional spray zones and a longer spray chamber were shown to decrease the occurrences of surface reheating and thereby mitigating midway cracking. Finally, recommendations were made for a spray cooling chamber appropriate for high speed casting.

description: Estimation of liquidity costs in futures markets is challenging because bid-ask spreads are usually not observed. Several estimators of liquidity costs exist that use transaction data, but there is little agreement on their relative accuracy and usefulness, and their performance has been questioned. We use a Bayesian method proposed by Hasbrouck which possesses conceptually desirable properties to estimate liquidity costs of six agricultural future contracts. The method builds on Roll's model and uses Markov Chain Monte Carlo estimation. Our Bayesian estimates are lower than more traditional estimates and as anticipated decrease even more when more realistic assumptions such as discreteness are incorporated. The findings demonstrate the need for further research to clarify the usefulness and accuracy of the procedure.

description: Context: Planets are formed amidst young circumstellar disks of gas and dust. The latter is traced by thermal radiation, where strong asymmetric clumps were observed in a handful of cases. These dust traps could be key to understand the early stages of planet formation, when solids grow from micron-size to planetesimals. Aims: Vortices are among the few known asymmetric dust trapping scenarios. The present work aims at predicting their characteristics in a complementary observable. Namely, line-of-sight velocities are well suited to trace the presence of a vortex. Moreover, the dynamics of disks is subject to recent developments. Methods: 2D hydro-simulations were performed where a vortex forms at the edge of a gas depleted region. We derived idealized line-of-sight velocity maps, varying disk temperature and orientation relative to the observer. The signal of interest, as a small perturbation to the dominant axisymetric component in velocity, may be isolated in observational data using a proxy for the dominant quasi-Keplerian velocity. We propose that the velocity curve on the observational major axis be such a proxy. Results: Applying our method to the disk around HD 142527 as a study case, we predict line-of-sight velocities scarcely detectable by currently available facilities, depending on disk temperature. We show that corresponding spirals patterns can also be detected with similar spectral resolutions, which will help discriminating against alternative explanations.

description: This paper investigates the relationship between the emerging coexistence of under and overweight and changes in socioeconomic conditions associated with economic growth in China during 1991-2000. Our key questions are: (1) whether any socioeconomic factor explains both increasing overweight and remaining underweight, (2) whether China's continuing economic growth leads to further increase in the prevalence of overweight, and (3) whether China's economic growth alone can lead to commensurate decrease in its remaining underweight. We find that changes in the pattern of job-related activity could partly explain both remaining underweight and increasing overweight, while overall income growth contributes to reducing both under and overweight. The effects of economic growth examined in this paper, particularly decreasing food prices, explain a large share of increasing overweight, and thus continuing economic growth is likely to lead to further increase in the revalence of overweight. Our empirical results also ndicate that there exist unobserved factors that significantly counteract the downward effects of economic growth on underweight rates, and thus economic growth alone is unlikely to lead to commensurate decrease in remaining underweight. To reduce remaining underweight more effectively, more direct interventions (e.g., micronutrient supplementation) may be needed.

description: Family support practices and its influence on senior secondary school adolescents’ socioemotional wellbeing in Port Harcourt city, Rivers State was studied. The study adopted the survey research design, with a study population of 8,332 public secondary school students in the 58 public secondary schools Port Harcourt City, Rivers State. The non-proportionate stratified random sampling technique was used to select 550 senior secondary school students for the study (275 males and 275 females). The instrument for data collection was a 65-item questionnaire designed on a four-point scale of Strongly Agree (SA), Agree (A), Strongly Disagree (SD) and Disagree (D) with scores 4, 3, 2, 1 respectively. Data were collected using the direct contact approach and the questionnaire return rate was 100%. Data obtained for this study were analyzed using mean scores and standard deviations. The decision rule was based on the midpoint for the scale of 2.50 Therefore, only mean scores of 2.50 and above were agreed with, while mean scores below 2.50 were regarded as disagreed with. The study revealed that marital instability and roles played by older family members have great impact on the social and emotional development of adolescents in Port Harcourt City, Rivers State. It is therefore recommended that families are sensitized on regular basis on the on the roles of older family members’ in either promoting or undermining adolescent socio-emotional wellbeing. Also, marital instability and spousal conflicts especially to the notice of the children should be discouraged.

Coupling with the finite volume method, the proposed schemes are extended to Euler equations with non-equilibrium reacting source terms. Benchmark tests are given to prove the prior order of accuracy and validate the positive-preserving property for both density and pressure.
112. Our Galaxy's central bar

description: While it has long been suspected that our own spiral Milky Way galaxy has a central bar, its structure, its orientation, and its pattern speed, are still subject to much debate. Gaia is helping to pin down all of these properties. Remarkably, Gaia's vast compilation of accurate stellar orbits provides a measure of the bar's deceleration!

description: The gauge independence of the dynamical fermion mass generated through chiral symmetry breaking in QED in a strong, constant external magnetic field is critically examined. We show that the bare vertex approximation, in which the vertex corrections are ignored, is a consistent truncation of the Schwinger-Dyson equations in the lowest Landau level approximation. The dynamical fermion mass, obtained as the solution of the truncated Schwinger-Dyson equations evaluated on the fermion mass shell, is shown to be manifestly gauge independent. By establishing a direct correspondence between the truncated Schwinger-Dyson equations and the 2PI (two-particle-irreducible) effective action truncated at the lowest nontrivial order in the loop expansion as well as in the 1/N_f expansion (N_f is the number of fermion flavors), we argue that in a strong magnetic field the dynamical fermion mass can be reliably calculated in the bare vertex approximation.

description: Linking the slow-roll scenario and the Dirac-Born-Infeld scenario of ultra-relativistic roll (where, thanks to the warp factor, the inflaton moves slowly even with an ultra-relativistic Lorentz factor), we find that the KKLMMT D3/anti-D3 brane inflation is robust, that is, enough e-folds of inflation is quite generic in the parameter space of the model. We show that the intermediate regime of relativistic roll can be quite interesting observationally. Introducing appropriate inflationary parameters, we explore the parameter space and give the constraints and predictions for the cosmological observables in this scenario. Among other properties, this scenario allows the saturation of the present observational bound of either the tensor/scalar ratio r (in the intermediate regime) or the non-Gaussianity f_NL (in the ultra-relativistic regime), but not both.

A method for measurement of the top quark mass using the mean decay length of b hadrons in ttbar events

description: We present a new method for the experimental determination of the top quark mass that is based upon the mean distance of travel of b hadrons in top quark events. The dominant systematic uncertainties of this method are not correlated with those of other methods, but alarge number of events is required to achieve small statistical uncertainty. Large ttbar event samples are expected from Run II of the Fermilab Tevatron and the CERN Large Hadron Collider (LHC). We show that by the end of Run II, a single experiment at the Tevatron could achieve a top quark mass uncertainty of ~5 GeV/c^2 by this method alone. At the CERN LHC, this method could be comparable to all others methods, which are expected to achieve an uncertainty of ~1.5 GeV/c^2 per experiment. This new method would provide a useful cross-check to other methods, and could be combined with them to obtain a substantially reduced overall uncertainty.

description: While contingent valuation (CV) methods have experienced growing popularity for estimating the willingness to pay for nonmarket goods and services, optimal bid designs for CV that provide guidance in bid point placement often render themselves impractical by relying on pretest or prior information about the true distribution for willingness to pay. We investigate the use of a practical alternative to existing optimal or robust bid designs called the uniform design. Uniform design randomly draws bid points from a predetermined uniform distribution. Analytics and simulations show that the uniform design has higher low-bound of relative efficiency at 84 percent of D-optimum than a robust design. Simulations also demonstrate that uniform design outperforms other optimal designs when initial information about true parameters is poor and even outperforms robust designs when the true values of parameters are known.

description: Modern radio telescopes are routinely reaching depths where normal starforming galaxies are the dominant observed population. Realising the potential of radio as a tracer of star formation and black hole activity over cosmic time involves achieving such depths over representative volumes, with radio forming part of a larger multiwavelength campaign. In pursuit of this we used the Karl G. Jansky Very Large Array (VLA) to image $\sim$5 deg$^{2}$ of the VIDEO/XMM-LSS extragalactic deep field at 1--2 GHz. We achieve a median depth of 16 $μ$Jy beam$^{-1}$ with an angular resolution of 4.5\arcsec. Comparisons with existing radio observations of XMM-LSS showcase the improved survey speed of the upgraded VLA: we cover 2.5 times the area and increase the depth by $\sim$20\% in 40\% of the time. Direction-dependent calibration and wide-field imaging were required to suppress the error patterns from off-axis sources of even modest brightness. We derive a catalogue containing 5,762 sources from the final mosaic. Sub-band imaging provides in-band spectral indices for 3,458 (60\%) sources, with the average spectrum becoming flatter than the canonical synchrotron slope below 1 mJy. Positional and flux-density accuracy of the observations, and the differential source counts are in excellent agreement with those of existing measurements. A public release of the images and catalogue accompanies this article.

description: The SL(2,Z) representation $π$ on the center of the restricted quantum group U_{q}sl(2) at the primitive 2p-th root of unity is shown to be equivalent to the SL(2,Z) representation on the extended characters of the logarithmic (1,p) conformal field theory model. The multiplicative Jordan decomposition of the U_{q}sl(2) ribbon element determines the decomposition of $π$ into a ``pointwise'' product of two commuting SL(2,Z) representations, one of which restricts to the Grothendieck ring; this restriction is equivalent to the SL(2,Z) representation on the (1,p)-characters, related to the fusion algebra via a nonsemisimple Verlinde formula. The Grothendieck ring of U_{q}sl(2) at the primitive 2p-th root of unity is shown to coincide with the fusion algebra of the (1,p) logarithmic conformal field theory model. As a by-product, we derive q-binomial identities implied by the fusion algebra realized in the center of~U_{q}sl(2).

description: Increasingly, grocery stores are marketing foods differentiated as locally produced. Freshness and taste are obvious reasons for consumer preference for these goods, but also important may be home-bias. Whatever the motive, there is substantial evidence that some consumers are willing to pay premium prices for food characterized as locally produced. A customer-intercept survey and a choice experiment of food shoppers in direct markets and traditional grocery stores was analyzed using Conjoint methods to evaluate WTP for characteristics related to locally grown fresh strawberries. Our results suggest that consumers are willing to pay more for locally produced berries: Customers intercepted in grocery stores would pay an average of 64 cents more per quart, while those intercepted at direct markets would pay nearly $1.17 more per carton of strawberries that was grown locally rather than berries identified simply as "produced in the U.S." These conclusions provide a solid rationale for the existence of niche market potential for local berry producers.

description: We investigate shot noise of photon-excited electron-hole pairs in open multi-terminal, multi-channel chaotic dots. Coulomb interactions in the dot are treated self-consistently giving a gauge-invariant expression for the finite frequency correlations. The Coulomb interactions decrease the noise, the strong interaction limit coincides with the non-interacting adiabatic limit. Inelastic scattering and dephasing in the dot are described by voltage and dephasing probe models respectively. We find that dephasing leaves the noise invariant, but inelastic scattering decreases correlations eventually down to zero.
