description: Alberta municipalities rely heavily on property taxes levied on residential and non-residential sectors to finance local public services. This paper investigates the effects of non-residential property tax rate on business investment using panel data from 17 Alberta cities over the 1998-2017 period. We find that a one mill increase in the non-residential property tax rate is associated with a $49 decrease in commercial and industrial real capita investment. Based on this estimate, we calculate the marginal cost of public funds for the non-residential property tax, which range from 3.12 for Lethbridge to 1.21 for Leduc. We also find that business taxes that are levied on the rental value of a business property have a negative impact on investment, while higher expenditures on municipal services do not have a significant effect on business investment.

description: We develop a general framework for multifunctional agriculture, which includes not only public goods but also rural viability as a non-public good item. We contribute to the literature in two ways. First, we demonstrate how the broader definition of multifunctional agriculture differs from the agri-environmental multifunctionality, and how agri-environmental policy should be reformed to include these aspects. We show that rural viability entails adjusting fertilizer tax and buffer strip subsidy below their first-best Pigouvian levels to reflect the direct and indirect employment effects of agricultural production. Moreover, we show that when non-agricultural land use is present, an additional, non-agricultural instrument is needed to adjust the amount of land allocated to agriculture to its optimal level. In a parametric model calibrated to Finnish agricultural conditions and Finnish valuation of agri-environmental amenities and rural viability, we assess how the socially optimal provision of non-public good multifunctionality relates the socially optimal agri-environmental multifunctionality.
The Plerionic Supernova Remnant G21.5-0.9: In and Out

description: The absence of a supernova remnant (SNR) shell surrounding the Crab and other plerions (pulsar wind nebulae) has been a mystery for 3 decades. G21.5-0.9 is a particularly intriguing plerionic SNR in which the central powering engine is not yet detected. Early Chandra observations revealed a faint extended X-ray halo which was suggested to be associated with the SNR shell; however its spectrum was nonthermal, unlike what is expected from an SNR shell. On the other hand, a plerionic origin to the halo is problematic since the X-ray plerion would be larger than the radio plerion. We present here our analysis of an integrated 245 ksec of archival Chandra data acquired with the High-Resolution Camera (HRC) and 520 ksec acquired with the Advanced CCD Imaging Spectrometer (ACIS). This study provides the deepest and highest resolution images obtained to date. The resulting images reveal for the first time 1) a limb-brightened morphology in the eastern section of the halo, and 2) a rich structure in the inner (40"-radius) bright plerion including wisps and a double-lobed morphology with an axis of symmetry running in the northwest-southeast direction. Our spatially resolved spectroscopic study of the ACIS-I data indicates that the photon index steepens with increasing distance from the central point source out to a radius of 40" then becomes constant at ~2.4 in the X-ray halo (for a column density N_H=2.2E22/cm^2). No line emission was found from the eastern limb; however marginal evidence for line emission in the halo's northern knots was found. This study illustrates the need for deep Chandra observations to reveal the missing SNR material in Crab-like plerions.

description: Heralded single photon sources are the most commonly used sources for optical quantum technology applications. There is strong demand for accurate prediction of their spectral features and temporal correlations with ever increasing precision. This is particularly important in connection with the intrinsically stochastic photon-pair generation process in heralded sources. Here we present a complete theoretical description of the temporal correlation of a signal-idler, signal-signal and signal-signal-idler coincidences of photons generated by continuous wave pumped cavity-enhanced spontaneous parametric down-conversion. The theory excellently predicts the measurements, which has been experimentally confirmed in our setup utilizing single photon detectors with high temporal resolution. This enables us to resolve and analyze the multi-photon correlation functions in great detail.

description: We report a multisite photometric campaign for the Beta Cephei star 12 Lacertae. 750 hours of high-quality differential photoelectric Stromgren, Johnson and Geneva time-series photometry were obtained with 9 telescopes during 190 nights. Our frequency analysis results in the detection of 23 sinusoidal signals in the light curves. Eleven of those correspond to independent pulsation modes, and the remainder are combination frequencies. We find some slow aperiodic variability such as that seemingly present in several Beta Cephei stars. We perform mode identification from our colour photometry, derive the spherical degree l for the five strongest modes unambiguously and provide constraints on l for the weaker modes. We find a mixture of modes of 0 <= l <= 4. In particular, we prove that the previously suspected rotationally split triplet within the modes of 12 Lac consists of modes of different l; their equal frequency splitting must thus be accidental. One of the periodic signals we detected in the light curves is argued to be a linearly stable mode excited to visible amplitude by nonlinear mode coupling via a 2:1 resonance. We also find a low-frequency signal in the light variations whose physical nature is unclear; it could be a parent or daughter mode resonantly coupled. The remaining combination frequencies are consistent with simple light-curve distortions. The range of excited pulsation frequencies of 12 Lac may be sufficiently large that it cannot be reproduced by standard models. We suspect that the star has a larger metal abundance in the pulsational driving zone, a hypothesis also capable of explaining the presence of Beta Cephei stars in the LMC.

description: In a qualitative study, the low-energy properties of the $\text{SO}\!\left(6\right)$-symmetric Quark-Meson-Diquark Model as an effective model for two-color Quantum Chromodynamics are investigated within the Functional Renormalization Group (FRG) approach. In particular, we compute the infrared scaling behavior of fluctuation-induced higher-derivative couplings of the linear Quark-Meson-Diquark Model and map the resulting renormalized effective action onto its nonlinear counterpart. The higher-derivative couplings of the nonlinear model, which we identify as the low-energy couplings of the Quark-Meson-Diquark Model, are therefore entirely determined by the FRG flow of their linear equivalents. This grants full access to their scaling behavior and provides insights into conceptual aspects of purely bosonic effective models, as they are treated within the FRG. In this way, the presented work is understood as an immediate extension of our recent advances in the $\text{SO}\!\left(4\right)$-symmetric Quark-Meson Model beyond common FRG approximations.

description: A multiperiod model based upon a multicriteria objective function has been developed for a representative area of the Guadalquivir Valley, dividing the irrigated area into homogeneous types of farming as identified by cluster analysis. The model was applied to different future scenarios with a time horizon of 10 years and several different farming environments. A set of eight sustainability indicators has been evaluated for the model. The results show that the evolution of crops over time is closely related to the political environment regarding the Common Agricultural Policy and the application of the Water Framework Directive. Methodological innovation has included the successful simultaneous introduction of MCDM and multiperiod programming techniques applied to agriculture and scenario development.

We obtain reliable values for the scaling exponent in the supercritical region for dimensions in the range $3.5\leq D\leq 14$. The critical exponent increases monotonically to an asymptotic value at large $D$ of $γ\sim0.466$. The data is well fit by a simple exponential of the form: $γ\sim 0.466(1-e^{-0.408 D})$.

A pipelined framework for multi-scale image comparison
Creators: name: Martindale, David M.
Publisher: name: University of British Columbia
Year: 2009

description: In this thesis we present a pipelined framework and a family of algorithms for determining meaningful differences between two images. The pipeline is structured in a way that makes it easy to use only a portion of the pipeline when that is appropriate, and any module in the pipeline can be replaced in its entirety by a new module that uses a different algorithm, while requiring minimal or no changes to other modules. Many pieces of the pipeline can be used individually. Three key design goals were to facilitate comparison of real images to computer-generated images, to take into account the sensitivity of the human visual system, and to accept pairs of images with arbitrary size differences and moderate misalignment in translation, rotation, and field of view. Most existing approaches fail badly at this task, requiring the two images to be of the same size and perfectly aligned with each other. The pipeline automatically aligns the two images as well as it can in the first four of its five phases. Images are first separated into octave-spaced bands of spatial frequencies, using the wavelet-based technique of Mallat and Zhong to find edges at multiple scales in each of the images. These edges are then matched using a graph-theoretic matching technique in the second phase, a least-squares fit is found for the alignment in the third phase, and the resulting transformation is applied using appropriate resampling in the fourth phase. The final phase of the pipeline computes difference measures for each spatial frequency band and three colour components, weighted according to the human contrast sensitivity function. The same Mallat-Zhong wavelet transform used for edge detection is used as the multi-band filter during comparison. We describe the pipeline and each component in detail, and discuss alternate approaches for each of the phases and generalizations of the framework. The flexibility of the framework is demonstrated by examples. We show how to restructure the data flow to implement an improved iterative multiscale alignment technique, and we analyze a Laplacian-based edge detector that could be used instead of wavelets.

description: This paper examines the competitiveness of cereal production in selected EU member states, during the period 1996 - 2000. Profitability was selected as a measure of competitive performance and costs of production, value of output and partial productivity indicators were examined as possible sources (potential) of competitive performance. Using data from the Farm Accountancy Data Network (FADN) the analysis showed that productivity levels in the UK, Ireland and France were consistently higher then competing countries Denmark, Germany and Italy. In terms of profitability, the opportunity cost of owned resources had a major impact on the competitiveness of cereal production within the EU. Cash costs as a percentage of total output were lowest in Italy but in terms of total economic costs, including an opportunity cost for all owned resources, Italy had the highest cost structure amongst the countries examine. These findings have implications for EU cereal producers in the medium term as direct payments are decoupled from production and producers must make production decisions based on full economic costs of production, including adequate remuneration for owned resources.

description: The Chandra Orion Ultradeep project (COUP) observation described in a companion paper by Getman et al. provides an exceptionally deep X-ray survey of the Orion Nebula Cluster and associated embedded young stellar objects. Membership of the region is important for studies of the stellar IMF, cluster dynamics, and star formation. The COUP study detected 1616 X-ray sources. In this study we confirm cloud membership for 1315 stars, identify 16 probable foreground field stars having optical counterparts with discrepant proper motions, and classify the remaining 285 X-ray sources, of which 51 are lightly and 234 heavily obscured. The 51 lightly obscured sources without known counterparts fall into three groups. (i) Sixteen are likely new members of the Orion Nebula Cluster. (ii) Two with unusually soft and non-flaring X-ray emission appear to be associated with nebular shocks, and may be new examples of X-rays produced at the bow shocks of Herbig-Haro outflows. (iii) The remaining thirty three are very weak uncertain sources, possibly spurious. Out of 234 heavily absorbed sources without optical or near-infrared counterparts 75 COUP sources are likely new embedded cloud members (with membership for 42 confirmed by powerful X-ray flares), and the remaining 159 are likely extragalactic AGN seen through the molecular cloud, as argued by a careful simulation of the extragalactic background population. Finally, a few new binary companions to Orion stars may have been found, but most cases of proximate COUP sources can be attributed to chance superpositions in this crowded field.

description: We propose a new construction of an integrable hierarchy associated to any infinite series of Frobenius manifolds satisfying a certain stabilization condition. We study these hierarchies for Frobenius manifolds associated to $A_N$, $D_N$ and $B_N$ singularities. In the case of $A_N$ Frobenius manifolds our hierarchy turns out to coincide with the KP hierarchy; for $B_N$ Frobenius manifolds it coincides with the BKP hierarchy; and for $D_N$ hierarchy it is a certain reduction of the 2-component BKP hierarchy. As a side product to these results we illustrate the enumerative meaning of certain coefficients of $A_N$, $D_N$ and $B_N$ Frobenius potentials.

description: Consumers increasingly demand multiple-quality attributes in food products and value reliable means to identify them. For producers, the effective communication of their products quality is a marketing strategy. Therefore, another market of information associated with the new food markets emerges. This market is closely linked to the institutional environment and the level of trust in different information sources. In this article the emphasis will be put on how the different quality signals provided by the firms in their products affect the consumers´ behaviour. The objective is to investigate domestic consumers' perceptions and beliefs about food quality information in Argentina to identify the mechanisms that fully guarantee this quality. The results indicate that domestic consumers´ perceptions about high quality products are more related to brand names than seals and certifications in labels. This has consequences upon the competitiveness of domestic food market. Quality certification and seller´s reputation are quality warranties restringed only to certain domestic market niches. The households´situation and occupational status seem to be more complex variables that resume the interaction between attitudes, information-processing and actions.

description: Sub-Saharan Africa (SSA) is the most important development challenge of the 21st century. Poverty is higher in most African countries than elsewhere in the developing world. According to the recently published Report of the Commission for Africa, economic growth in Africa is necessary for substantially reducing poverty. Among three proposed policy options, the Commission recommends that African countries invest significantly in agriculture. But policy makers in the region face a dilemma: which subsector within agriculture will yield the highest return for a given budget? This paper uses a computable general equilibrium model to simulate productivity gains in sub-Sahara African agriculture subject to trade-offs between gains in crops and gains in livestock. The simulated results suggest three conclusions. First, most of the sub-Sahara Africa economies gain more from research and development (R&D) investment in crops than from R&D investment in livestock but this conclusion is not true everywhere. The SACU (South African Customs Union) economies and Madagascar benefit from a sharing of R&D investment between crops and livestock. Second, when R&D is focused on food crops, a sharing of investment funds between crops and livestock is beneficial to other economies too. Third, in economies where a sharing of R&D investment between crops and livestock is beneficial (e.g., Botswana), general economic growth boosts the benefits from R&D investment in livestock.

description: Using new VLT/XShooter spectral observations we analyse the physical properties of five z~0.3-0.4 confirmed LyC leakers. Strong resonant MgII 2796,2803 emission lines (I(2796,2803)/I(Hbeta)=10-38 per cent) and non-resonant FeII* 2612,2626 emission lines are observed in spectra of five and three galaxies, respectively. We find high electron densities Ne~400cm-3, significantly higher than in typical low-z, but comparable to those measured in z~2-3 star-forming galaxies. The galaxies have a mean value of logN/O=-1.16, close to the maximum values found for star-forming (SF) galaxies in the metallicity range of 12+logO/H=7.7-8.1. All 11 low-z LyC emitting galaxies found by Izotov et al. (2016, 2018), including the ones considered in the present study, are characterised by high EW(Hbeta)~200-400A, high ionisation parameter (log(U)=-2.5 to -1.7), high average ionising photon production efficiency ξ= 10^{25.54} Hz erg-1 and hard ionising radiation. On the BPT diagram we find the same offset of our leakers from low-$z$ main-sequence SFGs as that for local analogues of LBGs and extreme SF galaxies at z~2-3. We confirm the effectiveness of the HeI emission lines diagnostics proposed by Izotov et al. (2017) in searching for LyC leaker candidates and find that their intensity ratios correspond to those in a median with low neutral hydrogen column density N(HI)=10^{17}-5x10^{17} cm-2 that permit leakage of LyC radiation, likely due to their density-bounded HII regions.

description: We study the dynamics of three elastic particles in a finite interval where two light particles are separated by a heavy ``piston''. The piston undergoes surprisingly complex motion that is oscillatory at short time scales but seemingly chaotic at longer scales. The piston also makes long-duration excursions close to the ends of the interval that stem from the breakdown of energy equipartition. Many of these dynamical features can be understood by mapping the motion of three particles on the line onto the trajectory of an elastic billiard in a highly skewed tetrahedral region. We exploit this picture to construct a qualitative random walk argument that predicts a power-law tail, with exponent -3/2, for the distribution of time intervals between successive piston crossings of the interval midpoint. These predictions are verified by numerical simulations.

description: The stress caused by the accumulation of salt in the soil tends to condition the establishment of farms in many regions worldwide. This factor particularly has a big impact in plant growth and is a restrictive factor in the production of many crops. These soils are generally characterized by low diversity of plant and microbial species, but well-adapted microbiota can thrive in these conditions and create interactions that may have great potential for osmotic stress alleviation and be a good source of new bioinoculants. Hence, some groups of bacteria are capable of supplying nutrients, such as phosphorus, potassium, or metal ions, even under high osmotic pressure in the soil, as well to develop protecting biofilm for roots or reduce ROS by the production of antioxidants.

description: With changes in the consumption pattern of meat, increases in urban population and underdeveloped distribution system after the collapse of the planned economy, there are increasing problems in meat supply and distribution in Mongolia, particularly in the capital city Ulaanbaatar. This paper examines the stages of meat distribution focusing on Khuchit Shonhor food market. Two types of informal wholesalers are identified; wholesalers who buy meat from nomads and transport it to the market in Ulaanbaatar, and wholesalers in the market who buy this meat and sell it to retailers operating within the market. It is assumed that the later wholesaler type has a stronger influence in price setting.

description: Raman spectroscopy is utilized to study the magnetic characteristics of heteroepitaxial NiO thin films grown by plasma-assisted molecular beam epitaxy on MgO(100) substrates. For the determination of the Néel temperature, we demonstrate a reliable approach by analyzing the temperature dependence of the Raman peak originating from second-order scattering by magnons. The antiferromagnetic coupling strength is found to be strongly influenced by the growth conditions. The low-temperature magnon frequency and the Néel temperature are demonstrated to depend on the biaxial lattice strain and the degree of structural disorder which is dominated by point defects.

description: Small countries may benefit from the formation of a trade bloc, since their combined market power will enable them to manipulate the terms of trade. The question of interest is whether countries will benefit from the enlargement of a trading bloc, if trade liberalization induces countries to substitute domestic support measures for conventional border protection. The paper deals with this question by analyzing the conditions for positive welfare effects resulting from the enlargement of a trade bloc. Based on a partial equilibrium trade model, we consider a game in production taxes/subsidies between two trade blocs. The tax/subsidy instrument may capture the production effect which can be induced by a combination of environmental, health or safety rules. The paper demonstrates that national welfare effects from the enlargement of a trading bloc depend crucially on a member country's net trade flow and the relative market power of the trade bloc. The theoretical analysis is supplemented by a numerical analysis estimating the potential welfare gains of EU enlargement on the major grain crop markets. Based on the scenarios that the EU operates either as a monopoly or competes with the rest of the world within a duopoly, upper and lower bounds of potential welfare effects resulting from enlargement are estimated. The results suggest that welfare effects on the major European grain markets are very small in proportion to the total production value. We thereby conclude that political reasons are likely to remain the main motivation for further EU enlargement.

description: Human activity and gesture recognition is an important component of rapidly growing domain of ambient intelligence, in particular in assisting living and smart homes. In this paper, we propose to combine the power of two deep learning techniques, the convolutional neural networks (CNN) and the recurrent neural networks (RNN), for automated hand gesture recognition using both depth and skeleton data. Each of these types of data can be used separately to train neural networks to recognize hand gestures. While RNN were reported previously to perform well in recognition of sequences of movement for each skeleton joint given the skeleton information only, this study aims at utilizing depth data and apply CNN to extract important spatial information from the depth images. Together, the tandem CNN+RNN is capable of recognizing a sequence of gestures more accurately. As well, various types of fusion are studied to combine both the skeleton and depth information in order to extract temporal-spatial information. An overall accuracy of 85.46% is achieved on the dynamic hand gesture-14/28 dataset.

description: We evaluate the effect of small scale inhomogeneities on large scale observations within the statistics of gravitationally lensed quasars. At this aim, we consider a cosmological model whose large scale properties (dynamics, matter distribution) are the same as in Friedmann-Lemaitre models, but whose matter distribution is locally inhomogeneous. We use the well known Dyer-Roder distances to allow a simple analytical expression of the optical depth, and pay particular attention on the different role played by the different notions of distances (filled beam angular diameter distance and Dyer-Roder distances) when calculating this quantity, following the prescription from Ehlers & Schneider for a coherent formalism. We find that the expected number of gravitationally lensed quasars is a decreasing function of the clumpiness parameter.

description: We report measurements and analysis of the specific heat and magnetocaloric effect at the phase boundary into the single magnetic field-induced phase (phase II) of U(Ru{0.96}Rh{0.04})2Si2, which yield striking similarities to the valence transition of Yb{1-x}YxInCu4. To explain these similarities, we propose a bootstrap mechanism by which a structural distortion causes an electric quadrupolar order parameter within phase II to become coupled to the 5f-electron hybridization, giving rise to a valence change at the transition.

S-R-T division algorithms as dynamical systems
Creators: name: McCann, Mark A.
Publisher: name: University of British Columbia
Year: 2009

description: S-R-T division, as it was discovered in the late 1950s [4, 19, 23], represented an important improvement in the speed of division algorithms for computers at the time. A variant of S-R-T division is still commonly implemented in computers today. Although some bounds on the performance of the original S-R-T division method were obtained, a great many questions remained unanswered. In this thesis, S-R-T division is described as a dynamical system. This enables us to bring modern dynamical systems theory, a relatively new development in mathematics, to bear on an older problem. In doing so, we are able to show that S-R-T division is ergodic, and is even Bernoulli, for all real divisors and dividends.

description: The osteoinductive property of strontium was repeatedly proven in the last decades. Compelling $\textit{in vitro}$ data demonstrated that strontium hydroxyapatite nanoparticles exert a dual action, by promoting osteoblasts-driven matrix secretion and inhibiting osteoclasts-driven matrix resorption. Recombinant human bone morphogenetic protein 2 (rhBMP2) is a powerful osteoinductive biologic, used for the treatment of vertebral fractures and critically-sized bone defects. Although effective, the use of rhBMP2 has limitations due its recombinant morphogen nature. In this study, we examined the comparison between two osteoinductive agents: rhBMP2 and the innovative strontium-substituted hydroxyapatite nanoparticles. To test their effectiveness, we independently loaded Gelfoam sponges with the two osteoinductive agents and used the sponges as agent-carriers. Gelfoam are FDA-approved biodegradable medical devices used as delivery system for musculoskeletal defects. Their porous structure and spongy morphology make them attractive in orthopedic field. The abiotic characterization of the loaded sponges, involving ion release pattern and structure investigation, was followed by $\textit{in vivo}$ implantation onto the periosteum of healthy mice and comparison of the effects induced by each implant was performed. The results demonstrated the use of sponges loaded with strontium nanoparticles as potential bone grafts might provide better outcomes for complex fractures. Strontium nanoparticles are a novel and effective non-biologic treatment for bone injuries and can be used as novel powerful therapeutics for bone regeneration.

description: It is the objective of this paper to provide a methodological framework for the analysis of regional marketing programs which include regional-origin labeling as well as quality assurance and control. Such programs are increasingly introduced in Europe and other parts of the world as a means against quality uncertainty in globalized markets. An equilibrium - displacement model is developed for a segmented market with differential qualities that can be utilized for a broad variety of marketing programs. It is applied to one selected European case, i.e. "Gepruefte Qualitaet - Bayern". It is shown that the price impacts on high-quality and low-quality segments depend crucially on substitutive relationships between the markets and the advertising elasticities. Welfare implications for producers in a program depend strongly on advertising elasticities, too, but also on the costs of participation including quality control and on the co-financing mechanism between government and producers.

description: This paper addresses the problem of biometric identification of animals, specifically dogs. We apply advanced machine learning models such as deep neural network on the photographs of pets in order to determine the pet identity. In this paper, we explore the possibility of using different types of "soft" biometrics, such as breed, height, or gender, in fusion with "hard" biometrics such as photographs of the pet's face. We apply the principle of transfer learning on different Convolutional Neural Networks, in order to create a network designed specifically for breed classification. The proposed network is able to achieve an accuracy of 90.80% and 91.29% when differentiating between the two dog breeds, for two different datasets. Without the use of "soft" biometrics, the identification rate of dogs is 78.09% but by using a decision network to incorporate "soft" biometrics, the identification rate can achieve an accuracy of 84.94%.

description: We study the spatial correlations of the one-dimensional KPZ surface for the flat initial condition. It is shown that the multi-point joint distribution for the height is given by a Fredholm determinant, with its kernel in the scaling limit explicitly obtained. This may also describe the dynamics of the largest eigenvalue in the GOE Dyson's Brownian motion model. Our analysis is based on a reformulation of the determinantal Green's function for the totally ASEP in terms of a vicious walk problem.

description: In this paper, we aim to address the problem of heterogeneous or cross-spectral face recognition using machine learning to synthesize visual spectrum face from infrared images. The synthesis of visual-band face images allows for more optimal extraction of facial features to be used for face identification and/or verification. We explore the ability to use Generative Adversarial Networks (GANs) for face image synthesis, and examine the performance of these images using pre-trained Convolutional Neural Networks (CNNs). The features extracted using CNNs are applied in face identification and verification. We explore the performance in terms of acceptance rate when using various similarity measures for face verification.
