description: Magnetism in recently discovered van der Waals materials has opened new avenues in the study of fundamental spin interactions in truly two-dimensions. A paramount question is what effect higher-order interactions beyond bilinear Heisenberg exchange have on the magnetic properties of few-atom thick compounds. Here we demonstrate that biquadratic exchange interactions, which is the simplest and most natural form of non-Heisenberg coupling, assume a key role in the magnetic properties of layered magnets. Using a combination of nonperturbative analytical techniques, non-collinear first-principles methods and classical Monte Carlo calculations that incorporate higher-order exchange, we show that several quantities including magnetic anisotropies, spin-wave gaps and topological spin-excitations are intrinsically renormalized leading to further thermal stability of the layers. We develop a spin Hamiltonian that also contains antisymmetric exchanges (e.g. Dzyaloshinskii-Moriya interactions) to successfully rationalize numerous observations currently under debate, such as the non-Ising character of several compounds despite a strong magnetic anisotropy, peculiarities of the magnon spectrum of 2D magnets, and the discrepancy between measured and calculated Curie temperatures. Our results lay the foundation of a universal higher-order exchange theory for novel 2D magnetic design strategies.

description: The nonlinear dynamics of a recently derived generalized Lorenz model (Macek and Strumik, Phys. Rev. E 82, 027301, 2010) of magnetoconvection is studied. A bifurcation diagram is constructed as a function of the Rayleigh number where attractors and nonattracting chaotic sets coexist inside a periodic window. The nonattracting chaotic sets, also called chaotic saddles, are responsible for fractal basin boundaries with a fractal dimension near the dimension of the phase space, which causes the presence of very long chaotic transients. It is shown that the chaotic saddles can be used to infer properties of chaotic attractors outside the periodic window, such as their maximum Lyapunov exponent.

description: The International Workshop & How to bring innovation in City/Region Food Systems” has been organized within the framework of the EU- H2020 project Food Systems in European Cities (FoodE, www.foode.eu), in collaboration with the 11th SPPS PhD Student Conference (https://sppsphd2020.fi/), held in Turku (Finland) and online in September 2-4, 2020. In recent years, our planet has been experiencing a convergence of natural and man-made crises that are unprecedented in our lifetime. We are facing the consequences of accelerating and rapid urbanization, the scarcity of natural resources and their mismanagement and the impact of major errors in our responses to disasters. Recent pandemic outbreak has posed at serious risk food access and security, especially in larger cities, enabling the environment for a constructive debate on how to rethink our food systems. While cities cover less than 2 percent of the Earth’s surface, they consume 78 percent of world energy and release over 60 percent of all carbon dioxide and a significant amount of other greenhouse gases. Among EU citizens, major environmental impact are associated with food systems, with all the related economic and social consequences. This workshop represents a place where young minds and early stage researchers are called to discuss about innovation and sustainability of City/Region Food Systems (CRFS), ranging from where food is produced, to where it is processed and distributed. Talks range among all aspects of CRFS, including innovative plant production systems, sustainability assessment, short food chain, food waste management, urban agriculture, business models and the water-food-energy nexus within cities. Speakers were asked to resume their innovative ideas and PhD research projects in three minutes, fulfilling the key questions: - What is the innovation of your research project? - How can this innovation contribute to sustainability of City/Region Food Systems? Within 1 h 30’, the workshop brought together 15 contributions (combining two plenary lectures and 13 short presentations from PhD candidates) from 9 World countries. All participants have got the opportunity to follow excellent presentations on topics that sometimes were far from their field of expertise, but though so much integrated and relevant to it.

description: This is a report of a customer intercept survey of customers in seven central Ohio grocery stores. Six were conventional stores of a national grocery chain (Traditional Grocery); of these, two were suburban , two were city central, and two were in predominately rural locations. The seventh store was a health/whole foods store (Specialty Grocery). The survey addressed customer willingness to pay for alternative levels of organic content in breakfast cereals, customer purchase patterns for organic foods, and customer opinions about the benefits of organic and other food characteristics. Forty-two percent of traditional grocery shoppers reported purchases of organic foods, the majority purchasing at least twice monthly. Shoppers in the specialty grocery were much more likely to purchase organic foods (92 percent). Consumers indicated a willingness to pay higher prices for processed foods with organic content. This willingness to pay varied with income and demographic characteristics of the households. Specialty grocery shoppers were more likely to purchase organic foods than their traditional grocery counterparts, and had a greater willingness to pay for these products.

description: We consider using optomechanical accelerometers as resonant detectors for ultralight dark matter. As a concrete example, we describe a detector based on a silicon nitride membrane fixed to a beryllium mirror, forming an optical cavity. The use of different materials gives access to forces proportional to baryon (B) and lepton (L) charge, which are believed to be coupling channels for vector dark matter particles ("dark photons"). The cavity meanwhile provides access to quantum-limited displacement measurements. For a centimeter-scale membrane pre-cooled to 10 mK, we argue that sensitivity to vector B-L dark matter can exceed that of the Eöt-Wash experiment in integration times of minutes, over a fractional bandwidth of $\sim 0.1\%$ near 10 kHz (corresponding to a particle mass of $10^{-10}$eV/c$^2$). Our analysis can be translated to alternative systems such as levitated particles, and suggests the possibility of a new generation of table-top experiments.

description: We study the phenomenon of system size stochastic resonance within the nonequilibrium potential's framework. We analyze three different cases of spatially extended systems, exploiting the knowledge of their nonequilibrium potential, showing that through the analysis of that potential we can obtain a clear physical interpretation of this phenomenon in wide classes of extended systems. Depending on the characteristics of the system, the phenomenon results to be associated to a breaking of the symmetry of the nonequilibrium potential or to a deepening of the potential minima yielding an effective scaling of the noise intensity with the system size.

description: In this paper, statistical and economic analyses are used in identifying, analyzing, and modeling the relationships among citizen complaints, swine production and community characteristics, EPA inspections, and regulatory violations. The primary results of this research include assessments of factors that affect citizen complaints and factors that affect the probability of regulatory violations. In addition, the analyses also provide statistical results of a comparison of the efficiencies of different types of site inspections in regulatory violation detection. Our results provide information valuable for understanding issues surrounding the development of the swine production industry and local communities.

description: The 2002 Farm Act allowed farm owners to update base acres for direct payments (DPs) and counter-cyclical payments (CCPs) and to update yields for counter-cyclical payments. A minority, about 40 percent, of the 1.9 million enrolled farms choose to update their base acres using 1998-2001 plantings; of these updating farms about three-fourths updated their payment yield for CCPs. Producers with rice and cotton base had a strong economic incentive to maximize base acres for those crops, either by retaining previous base acres if they had shifted to production of alternative crops or by increasing base if they had expanded rice or cotton plantings. Research findings support the hypothesis that base designation reflects payment maximization criteria.

This separation is measured by the so-called separation constant, which is defined in terms of the pseudohyperbolic metric. Moreover, we study general properties of related extremal functions and associated vectors. Throughout, compressions of the shift serve as illustrating examples which also allow for refined results.

description: In this study we use data envelopment analysis (DEA), and an extension of DEA called value efficiency analysis (VEA), to explore the production of quality of life within counties in the mid-Atlantic region and the extent to which production frontiers and efficiency differ between rural and urban counties. These methods allow us to identify counties that are inefficient in their quality of life production, and to rank those counties according to their distance from a performance standard established by other observed counties (using DEA), or by a single unit designated as most preferred (using VEA) .

description: This paper presents a validation experiment of a global CGE trade model widely used for analysis of trade liberalization. We focus on the ability of the model to reproduce price volatility in wheat markets. The literature on model validation is reviewed with an eye towards designing an appropriate methodology for validating large scale CGE models. The validation experiment results indicate that in its current form, the GTAP-AGR model is incapable of reproducing wheat market price volatility and that trade and poverty analysis taking these prices as inputs might be wrongly influenced. We conclude that model validation is tractable and an important component of analysis, as it points to areas to consider for refining analysis. In the specific case presented here, it seems that the Armington structure and trade elasticities are influential in whether the model over our under predicts price volatility for a specific region based on its net trade position for wheat.

description: Sensor-based precision fertilizer technologies are being developed and researched by production scientists. One such technology uses normalized difference vegetation index (NDVI) reflectance measurements of growing winter wheat plants and a nitrogen fertilizer optimization algorithm (NFOA) to determine nitrogen requirement necessary for plants to reach their yield plateau. A number of precision fertilizer application systems that use this technology are considered in this paper. A linear response stochastic plateau wheat yield function conditional on NDVI reflectance measurements is estimated and used within an expected profit-maximization framework to estimate upper bounds on the returns from the precision nitrogen application systems. The on-the-go precision system that assumes perfect information was approximately $7 per acre more profitable than the convention of applying 80 pounds of nitrogen prior to planting in the fall. The whole-field precision system was break-even with conventional methods.
An experimental study on the seismic interaction of flexible conductors with electrical substation equipment
Creators: name: Ghalibafian, Houman
Publisher: name: University of British Columbia
Year: 2009

description: Flexible conductors are usually employed to interconnect equipment items in electrical substations located on seismically active regions. They have sufficient slack, which allows the conductor to accommodate the relative displacement of the interconnected equipment under seismic loading. Generally, in the design process of the interconnected equipment and their connections to the flexible conductors, the seismic behavior of the conductors is not considered and the dynamic forces generated by them during an earthquake event are not taken into account. However, these forces could be significant and could overload the equipment and cause damage. This thesis presents an investigation on the seismic behavior of a class of high voltage flexible conductors by evaluating their interaction with and their effect on the equipment to which they are connected. This was done by performing various experimental tests on one of the most commonly used configurations of flexible conductors in substations throughout the province of British Columbia in Canada. The experiments included a quasi-static test on the full-scale flexible conductor and four series of shake table tests on the large scale models of the equipment in their stand-alone or interconnected set-up. The design of the equivalent models of the equipment was based on the stiffness and the natural frequencies of the actual equipment obtained from field tests. The input signals for the shake table were synthetic earthquakes. Three records from earthquakes in California were modified to fit the IEEE (the Institute of Electrical and Electronics Engineers) and BC Hydro prescribed design spectra. The specimens were instrumented throughout with acceleration and displacement transducers. Two multi-axial load cells were employed to measure the loads generated at the connections of the conductor to the equivalent equipment during the tests. The test results are summarized and presented in various forms. Various analyses including spectral analysis is performed on the test results and comparisons are made between the results of various tests and various analyses. This investigation showed that the dynamic effect of the flexible conductors should be considered while evaluating the seismic capacity of the interconnected equipment.

description: This study explores the short-run and long-run relationships between the U.S. agricultural trade balance and domestic macroeconomic aggregates and agricultural variables. We use cointegration analysis and a vector error-correction model with quarterly data for 1981-2003. The results show that, in the long-run, the exchange rate, agricultural price, and disposable income are weakly exogenous in the U.S. agricultural sector and have significant effects on the trade balance. The combined short-run dynamic effects of the exchange rate, agricultural price and production, and disposable income jointly explain changes in the trade balance.

description: We study the properties, connectivity, and galaxy content of groups and filaments in the low-density region (cocoon) around A2142 supercluster (SClA2142). We traced the SClA2142 cocoon boundaries by the lowest luminosity-density regions that separate SClA2142 from other superclusters. We determined galaxy filaments and groups in the cocoon and analysed the connectivity of groups, the high density core (HDC) of the supercluster, and the whole of the supercluster. We compared the distribution and properties of galaxies with different star-formation properties in the supercluster and in the cocoon. SClA2142 and the long filament that is connected to it forms the longest straight structure in the Universe detected so far, with a length of $75$ $h^{-1}$ Mpc. The connectivity of the supercluster is C = 6 - 7; poor groups have C = 1 - 2. Long filaments around the supercluster's main body are detached from it at the turnaround region. Galaxies with very old stellar populations lie in systems across a wide range of richness from the richest cluster to poorest groups and single galaxies. They lie even at local densities as low as $D1 < 1$ in the cocoon and up to $D1 > 800$ in the supercluster. Recently quenched galaxies lie in the cocoon mainly in one region and their properties are different in the cocoon and in the supercluster. The star-formation properties of single galaxies are similar across all environments. The collapsing main body of SClA2142 with the detached long filaments near it are evidence of an important epoch in the supercluster evolution. Further studies are needed to understand the reasons of similarity of galaxies with very old stellar populations in extremely different environments. The presence of long, straight structures in the cosmic web may serve as a test for cosmological models.

description: We report the first detection, with Chandra, of X-ray emission from the jet of the powerful narrow-line radio galaxy 3C 346. X-rays are detected from the bright radio and optical knot at which the jet apparently bends by about 70 degrees. The Chandra observation also reveals a bright galaxy-scale atmosphere within the previously-known cluster, and provides a good X-ray spectrum for the bright core of 3C 346. The X-ray emission from the knot is synchrotron radiation, as seen in lower-power sources. In common with these sources, there is evidence of morphological differences between the radio/optical and X-ray structures, and the spectrum is inconsistent with a one-component continuous-injection model. We suggest that the X-ray-bright knot is associated with a strong oblique shock in a moderately relativistic, light jet, at about 20 degrees to the line of sight, and that this shock is caused by the jet interacting with the wake in the cluster medium behind 3C 346's companion galaxy. The general jet curvature can result from pressure gradients in the cluster atmosphere.

description: In this paper, we offer an insight into the state of TPACK as represented in teaching methods with the use of technology in the school classroom English as a foreign language teacher. By means of inductive content analysis of the e-versions of scientific journals based research articles on technology in English teaching as published in the years 2010-2016, we capture the pace and development of technology implementation process in this subject. We offer an interpretation of the developed approaches associated with the use of technologies in class as one of the key indicators of TPACK in action. In our qualitative content analysis, we found formally centralized, modern methods and post-methods based approaches resulting in practice regarding the use of technology in teaching English. Since compared to formally centralized practices, modern and post-modern based teaching as based on the social constructivist educational process, we argue in support of TPACK developing as a comprehensive model in actions of teacher’s classroom practices based on post-methods approaches.

description: We discuss the influence of the cosmological constant on the gravitational equations of motion of bodies with arbitrary masses and eventually solve the two-body problem. Observational constraints are derived from measurements of the periastron advance in stellar systems, in particular binary pulsars and the solar system. Up to now, Earth and Mars data give the best constraint, Lambda < 10^{-36} km^{-2}; bounds from binary pulsars are potentially competitive with limits from interplanetary measurements. If properly accounting for the gravito-magnetic effect, this upper limit on $Λ$ could greatly improve in the near future thanks to new data from planned or already operating space-missions.

description: In this article we price a precipitation option based on empirical weather data from Germany using different pricing methods, among them Burn Analysis, Index Value Simulation and Daily Simulation. For that purpose we develop a daily precipitation model. Moreover, a de-correlation analysis is proposed to assess the spatial basis risk that is inherent to rainfall derivatives. The models are applied to precipitation data in Brandenburg, Germany. Based on simplifying assumptions of the production function, we quantify and compare the risk exposure of grain producers with and without rainfall insurance. It turns out that a considerable risk remains with producers who are remotely located from the weather station. Another finding is that significant differences may occur between the pricing methods. We identify the strengths and weaknesses of the pricing methods and give some recommendations for their applications. Our results are relevant for producers as well as for potential sellers of weather derivatives.

description: Consumer concerns in food purchasing contain a number of elements, including food safety, environment, animal welfare, and other social issues. The purpose of this study was to examine consumer perceptions of the potential benefits of products that are produced using an environmental management system (EMS) in agriculture, and to identify those factors that influence choice. The choice modeling technique uses consumer responses (preferences) to estimate Montrealers= willingness to pay (WTP) for production practices that decrease the impacts on the environment, as well as for other potential benefits of EMS production. Results indicate that consumers are willing to pay a price premium for these environmental benefits. This could provide a justification for government to provide incentives for environmental farm management practices and support to certification and labelling programs.

The proof proceeds by demonstrating the curves in question satisfy a two-part criterion given by Anderson and Ihara. Two proofs of the second part of the criterion are provided; the first relies on a theorem of Shimura, while the second uses the moduli interpretation.

description: In the context of test case based automatic program repair (APR), patches that pass all the test cases but fail to fix the bug are called overfitted patches. Currently, patches generated by APR tools get inspected manually by the users to find and adopt genuine fixes. Being a laborious activity hindering widespread adoption of APR, automatic identification of overfitted patches has lately been the topic of active research. This paper presents engineering details of ObjSim: a fully automatic, lightweight similarity-based patch prioritization tool for JVM-based languages. The tool works by comparing the system state at the exit point(s) of patched method before and after patching and prioritizing patches that result in state that is more similar to that of original, unpatched version on passing tests while less similar on failing ones. Our experiments with patches generated by the recent APR tool PraPR for fixable bugs from Defects4J v1.4.0 show that ObjSim prioritizes 16.67% more genuine fixes in top-1 place. A demo video of the tool is located at https://bit.ly/2K8gnYV.

Subjects: Consumer/Household Economics

description: Zeroes expenditure represent a difficulty in the analysis of household survey data. Zero expenditures are the result of two phenomena: nonconsumption and infrequency of purchase. Distinguishing between these types of zeroes is difficult in the kinds of data of interest to agricultural economists. This paper proposes a novel approach that yields less biased estimates of latent expenditure when the cause of the zeroes is unknown.

description: One strand of literature shows a household's cost of food to vary with the household's own income and demographic characteristics. For example, low-income households may tend to purchase less costly bundles of food. However, a separate strand of literature also shows food prices to vary spatially with the characteristics of communities, such as real estate prices. In this study, a model is developed that unites these two strands. Simulations further illustrate the effect that a community's characteristics can have on a household's food budget, if the household lives in each of ten cities in the United States.

description: Post-transductional modifications tune the functions of proteins and regulate the collective dynamics of biochemical networks that determine how cells respond to environmental signals. For example, protein phosphorylation and nitrosylation are well-known to play a pivotal role in the intracellular transduction of activation and death signals. A protein can have multiple sites where chemical groups can reversibly attach in processes such as phosphorylation or nitrosylation. A microscopic description of these processes must take into account the intrinsic probabilistic nature of the underlying reactions. We apply combinatorial considerations to standard enzyme kinetics and in this way we extend to the dynamic regime a simplified version of the traditional models on the allosteric regulation of protein functions. We link a generic modification chain to a downstream Michaelis-Menten enzymatic reaction and we demonstrate numerically that this accounts both for thresholds and long time delays in the conversion of the substrate by the enzyme. The proposed mechanism is stable and robust and the higher the number of modification sites, the greater the stability. We show that a high number of modification sites converts a fast reaction into a slow process, and the slowing down depends on the number of sites and may span many orders of magnitude; in this way multisite modification of proteins stands out as a general mechanism that allows the transfer of information from the very short time scales of enzyme reactions (milliseconds) to the long time scale of cell response (hours).

description: Factors influencing the adoption of Russian Varroa-Resistant honey bees were assessed using a double hurdle model. Results indicate factors associated with the adoption include sales over $1,000 of bee related products, residence in the delta states, internet use, and membership in the AHPA. Negatively associated factors are high percentage of income coming from beekeeping, and membership in the ABF. Intensity of adoption increased with frequent contact with the USDA, and decreased with greater colony size, sales and membership in the ABF.

Improved approaches to manage road safety infrastructure

Publisher: name: University of British Columbia
Year: 2009

description: Due to the importance of road safety, most road authorities and safety agencies employ some type of road safety management program, designed to improve the safety performance for the system users. One road safety management program is delivered through road planning and engineering, aimed to improve the road design features to reduce the frequency and/or severity of collisions. These road safety management programs can be divided into two categories: reactive road safety initiatives (i.e., responding to existing road safety problems) and proactive road safety initiatives (i.e., actions taken to prevent the emergence of problems). There are several problems with the two approaches to deliver road safety. First, deteriorating quality and quantity of collision data, necessary for safety analysis, is jeopardizing the success of reactive safety management programs. Secondly, the inherent nature of a reactive program is problematic (i.e., allowing problems to emerge before treatment) and that the area of influence is limited, responding only to the most problematic locations. A proactive approach to road safety management can address these problems, however a proactive approach is a new concept and suffers from a lack of procedural and evaluation techniques. The goal of this research work is to explore new opportunities to improve the evaluation techniques and processes used in support of effective road safety management. This work offers four separate contributions that attempt to achieve this goal. First, explore the use of auto insurance claims data for road safety analysis, addressing the problem of a dependency on the deteriorating collision data. Second, develop a subjectively based, observation technique that can be used for road safety analysis, based on a concept of road-user risk, to address the collision data problem. Third, provide a framework and process to support proactive road safety planning, describing how the safety evaluation tools should be applied. Fourth, introduce improved techniques to evaluate proactive road safety management by developing collision prediction models. Each of the four attempts to improve the evaluation techniques and processes used in support of effective road safety management has proven to be successful, as described in detail in this thesis.
Edge Magnetoplasmons in Quantum Hall Line Junction Systems

description: A quantum Hall line junction system consists of a one-dimensional Luttinger liquid (LL) and two chiral channels that allow density waves incident upon and reflected by the LL to be measured separately. We demonstrate that interactions in a quantum Hall line junction system can be probed by studying edge magnetoplasmon absorption spectra and their polarization dependences. Strong interactions in the junction lead to collective modes that are isolated in either Luttinger liquid or contact subsystems.

description: We specify several count data models, parameterizing the probability densities in terms of their means for easier comparison between models. In addition, we derived a correction of these probability densities for differences in sample sizes, which is a contribution to the count data literature as far as we are aware. We then empirically implement these models using data from a mail survey of firms using prescribed fire to estimate the expected number of escapes from prescribed burns. We find that the not correcting for sample size differences can lead to erroneous conclusions concerning the statistical significance of variables.

description: Statistical observations of the Epoch of Reionization using the 21 cm line of neutral hydrogen have the potential to revolutionize our understanding of structure formation and the first luminous objects. However, these observations are complicated by a host of strong foreground sources. Several foreground removal techniques have been proposed in the literature, and it has been assumed that these would be used in combination to reveal the Epoch of Reionization (EOR) signal. By studying the characteristic subtraction errors of the proposed foreground removal techniques, we identify an additional subtraction stage that can further reduce the EOR foreground contamination, and study the interactions between the foreground removal algorithms. This enables us to outline a comprehensive foreground removal strategy that incorporates all previously proposed subtraction techniques. Using this foreground removal framework and the characteristic subtraction errors, we discuss the complementarity of different foreground removal techniques and the implications for array design and the analysis of EOR data.
