description: This study examines the factors that determine the likelihood of submitting a potentially fraudulent prevented planting claim. A theoretical model is developed and the theoretical predictions are empirically verified by utilizing a binary choice model and crop insurance data from the southern United States. The empirical results show that insured producers with higher prevented planting coverage, lower dollar value of expected yield, and a history of submitting prevented planting claims are more likely to submit an anomalous prevented planting claim. The empirical model also suggests revenue insurance plans may be more vulnerable to prevented planting fraud than the traditional yield-based insurance plan. Results of this study can be valuable to compliance offices in their efforts to find "indicators" of fraudulent behavior in crop insurance, especially with regard to prevented planting.

description: We propose and experimentally demonstrate the Transformable Reflective Telescope (TRT) Kit for educational purposes and for performing various optical tests with a single kit. The TRT Kit is a portable optical bench setup suitable for interferometry, spectroscopy, measuring stray light, and developing adaptive optics, among other uses. Supplementary modules may be integrated easily thanks to the modular design of the TRT Kit. The Kit consists of five units; a primary mirror module, a secondary mirror module, a mounting base module, a baffle module, and an alignment module. Precise alignment and focusing are achieved using a precision optical rail on the alignment module. The TRT Kit transforms into three telescope configurations: Newtonian, Cassegrain, and Gregorian. Students change telescope configurations by exchanging the secondary mirror. The portable design and the aluminum primary mirror of the TRT Kit enable students to perform experiments in various environments. The minimized baffle design utilizes commercial telescope tubes, allowing users to look directly into the optical system while suppressing stray light down to $\sim$10$^{-8}$ point source transmittance (PST). The TRT Kit was tested using a point source and field images. Point source measurement of the Newtonian telescope configuration resulted in an 80\% encircled energy diameter (EED) of 23.8 $μ$m.

description: This study investigates the effects on the U.S. cotton industry of textile trade liberalization using a multi-market equilibrium displacement model. The simulation results suggest that textile trade liberalization would induce small changes in the total demand for U.S. cotton but would affect considerable y U.S. cotton demand structure, making U. S, cotton growers more dependent on world markets. The welfare analyses reveal that textile trade liberalization would result in a small welfare loss for U, S. cotton producers. As expected, textile trade liberalization also would lead to considerable substitution of imports for domestic production and substantial declines in prices of all textile products.

description: Voltage-controlled spintronic devices utilizing the spin degree of freedom are desirable for future applications, and may allow energy-efficient information processing. Pure spin current can be created by thermal excitations in magnetic systems via the spin Seebeck effect (SSE). However, controlling such spin currents, only by electrical means, has been a fundamental challenge. Here, we investigate voltage control of the SSE in the antiferromagnetic insulator Cr2O3. We demonstrate that the SSE response generated in this material can be effectively controlled by applying a bias voltage, owing to the sensitivity of the SSE to the orientation of the magnetic sublattices as well as the existence of magnetoelectric couplings in Cr2O3. Our experimental results are explained using a model based on the magnetoelectric effect in Cr2O3.

description: We study the statistical mechanics of a class of problems whose phase space is the set of permutations of an ensemble of quenched random positions. Specific examples analyzed are the finite temperature traveling salesman problem on several different domains and various problems in one dimension such as the so called descent problem. We first motivate our method by analyzing these problems using the annealed approximation, then the limit of a large number of points we develop a formalism to carry out the quenched calculation. This formalism does not require the replica method and its predictions are found to agree with Monte Carlo simulations. In addition our method reproduces an exact mathematical result for the Maximum traveling salesman problem in two dimensions and suggests its generalization to higher dimensions. The general approach may provide an alternative method to study certain systems with quenched disorder.

description: Generative adversarial network (GAN) has been shown to be useful in various applications, such as image recognition, text processing and scientific computing, due its strong ability to learn complex data distributions. In this study, a theory-guided generative adversarial network (TgGAN) is proposed to solve dynamic partial differential equations (PDEs). Different from standard GANs, the training term is no longer the true data and the generated data, but rather their residuals. In addition, such theories as governing equations, other physical constraints and engineering controls, are encoded into the loss function of the generator to ensure that the prediction does not only honor the training data, but also obey these theories. TgGAN is proposed for dynamic subsurface flow with heterogeneous model parameters, and the data at each time step are treated as a two-dimensional image. In this study, several numerical cases are introduced to test the performance of the TgGAN. Predicting the future response, label-free learning and learning from noisy data can be realized easily by the TgGAN model. The effects of the number of training data and the collocation points are also discussed. In order to improve the efficiency of TgGAN, the transfer learning algorithm is also employed. Numerical results demonstrate that the TgGAN model is robust and reliable for deep learning of dynamic PDEs.

description: The ratio between the proton and electron masses is shown to be close to the ratio between the strong and electromagnetic interaction coupling constants at Extremely Low Energy (ELE). Based on the experimental data, this relation has been extended for the weak and gravitational interactions, too. Thus, a mass relation has been found, according to which the rest mass of the Lightest Free Massive Stable Particle (LFMSP), acted upon by a particular interaction, is proportional to the coupling constant of the respective interaction at ELE. On the basis of this mass relation, the electron neutrino and graviton masses have been approximately estimated to 2.1x10^(-4) eV/c^2 and 2.3x10^(-34) eV/c^2, respectively. The last value is of the order of the magnitude of hbar*H/c^2, where H is the Hubble constant and hbar is the reduced Planck constant. It is worth noting that this value has been obtained by fundamental constants only, without consideration of any cosmological models.

description: Fines migration behavior can either promote or obstruct fluid flow within the reservoir and is crucial for productivity optimization that needs fundamental understanding. The present work focuses on the contributions from effective stress build-up due to reservoir depletion and decreases in brine salinity from low-salinity water injection. Particle detachment is studied analytically by using the critical retention concentration function modified with stress and salinity dependents. Increase in formation effective stress leads to deformations within the reservoir configurations due to micro-cracks and reduced pore dimensions. Decreased size of the travelling channels promotes particle detachment, while the critical retention concentration decreases. A sensitivity study reveals that, under influence of effective stress, particle size and fluid velocity are dominant parameters controlling the fines migration by influencing the particle detaching forces. With decreasing brine salinity (e.g. via low-salinity water injection), clay particles that are attached on the pore surface increasingly swell, leading to reduction in effective pore space and flow channel. Decreased pore space directly obstructs travelling of suspended particles and fluids which results in permeability decline. Initial clay particle size is found to be a critical factor controlling particle detachment behavior. Small initial particle sizes are not likely to detach from the pore surface as a result of weak detaching forces, hence the analysis finds the critical retention concentration unchanged resulting in negligible permeability decline as a function of brine salinity. Considering both effects, effective stress and brine salinity, stress-dependent effects dominate salinity-dependent effects at low effective stress while the two contribute equally at high effective stress.

description: Short-run and long-run technical and allocative efficiencies were computed for 395 New York dairy farms using data envelopment or nonparametric procedures on 1990 Dairy Farm Business Summary data. The farms were, on average, more allocatively efficient in the short run than in the long run, but were more technically efficient in the long run than in the short run. Stanchion barns were as efficient as milking parlors, and milking more than two times per day did not increase efficiency.

description: We present new medium-band uvby Stromgren and broad-band VI photometry for the central regions of the globular cluster Omega Cen. From this photometry we have obtained differential reddening estimates relative to two other globular clusters (M13 and NGC288) using a metallicity-independent, reddening-free temperature index, [c]=(u-v)-(v-b) - 0.2(b-y), for hot horizontal-branch (HB) stars (T_e> 8,500K). We estimate color excesses of these hot HB stars using optical and near-infrared colors, and find clumpy extinction variations of almost a factor of two within the area of the cluster core. In particular, the greatest density of more highly reddened objects appears to be shifted along the right ascension axis when compared with less reddened ones. These findings complicate photometric efforts to investigate the star formation history of Omega Cen.

description: The Geothermal Battery Energy Storage concept has been proposed to provide large-scale heat storage when solar radiance is available, to be later recovered for economic benefit. The concept uses solar radiance to heat water on the surface which is then injected into a suitable subsurface formation. This hot water elevates the ambient formation temperature creating a high-temperature geothermal reservoir acceptable for geothermal electricity generation or direct heat applications. The process uses produced/injected, connate formation water and thus neither freshwater nor surface storage or disposal of water is required. This concept has been previously presented in several publications and presentations. Calculations of reservoir temperature and pressure profiles in isotropic and homogeneous reservoirs have been published previously by the authors. These calculations have shown that a small volume of rock mass is required for the heat storage reservoir, of the order of tens of meters radius from an injection well in a reservoir of one-hundred meters thickness. It was shown that over ninety percent of heat can be recovered for certain reservoirs. The previous calculations for the Geothermal Battery Energy Storage considered only isotropic and homogeneous reservoir formation properties. However, even in a small rock mass volume, considering sedimentary depositional environments and superimposed tectonics, the rock permeability may be anisotropic and heterogeneous with reservoir layers of different properties. Calculations are presented here considering anisotropic permeabilities, and layered heterogeneous permeabilities i.e., formations with horizontal layers of different permeabilities. Such reservoir properties create non-symmetrical temperature and pressure profiles away from a well, which is critical for well layout and planning for injection and production.
Use of problem-based learning for in-service teacher training in computer integration in the classroom
Creators: name: Yusyp, Maryjanne
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this case study was to understand and describe teachers' responses to the use of problem-based learning as a model for in-service professional development in computer technology integration. Seven urban high school teachers from different disciplines used 8 release days over a 3 1/2-month period to work collaboratively to address an ill-structured problem. Data was gathered from interviews, self-administered questionnaires, on-line discussions, observations and teachers' own reflective writings. A problem-based learning model can provide positive professional development experiences for teachers in technology integration. Teachers in this study valued and benefited from the learning opportunities this model provided particularly the support over time, purposeful work, group collaboration, and time for discussion and reflection. However, for PBL to be a more effective model for teacher professional development in technology integration, it may need to be adapted to meet the specific needs of teachers and the context in which they work.

description: This paper presents accurate spectral energy distributions (SEDs) of 16 M31 globular clusters (GCs) confirmed by spectroscopy and/or high spatial-resolution imaging, as well as 30 M31 globular cluster candidates detected by Mochejska et al. Most of these candidates have m_V > 18, deeper than previous searches, and these candidates have not yet been confirmed to be globular clusters. The SEDs of these clusters and candidates are obtained as part of the BATC Multicolor Survey of the Sky, in which the spectrophotometrically-calibrated CCD images of M31 in 13 intermediate-band filters from 4000 to 10000 A were observed. These filters are specifically designed to exclude most of the bright and variable night-sky emission lines including the OH forest. In comparison to the SEDs of true GCs, we find that some of the candidate objects are not GCs in M31. SED fits show that theoretical simple stellar population (SSP) models can fit the true GCs very well. We estimate the ages of these GCs by comparing with SSP models. We find that, the M31 clusters range in age from a few ten Myr to a few Gyr old, as well as old GCs, confirming the conclusion that has been found by Barmby et a, Williams & Hodge, Beasley et al., Burstein et al. and Puzia et al. in their investigations of the SEDs of M31 globular clusters.

Semi-analytic Expressions for the Isolation and Coupling of Mixed Modes

description: In the oscillation spectra of giant stars, nonradial modes may be seen to undergo avoided crossings, which produce a characteristic "mode bumping" of the otherwise uniform asymptotic p- and g-mode patterns in their respective echelle diagrams. Avoided crossings evolve very quickly relative to typical observational errors, and are therefore extremely useful in determining precise ages of stars, particularly in subgiants. This phenomenon is caused by coupling between modes in the p- and g-mode cavities that are near resonance with each other. Most theoretical analyses of the coupling between these mode cavities rely on the JWKB approach, which is strictly speaking inapplicable for the low-order g-modes observed in subgiants, or the low-order p-modes seen in very evolved red giants. We present both a nonasymptotic prescription for isolating the two mode cavities, as well as a perturbative (and also nonasymptotic) description of the coupling between them, which we show to hold good for the low-order g- and p-modes in these physical situations. Finally, we discuss how these results may be applied to modelling subgiant stars and determining their global properties from oscillation frequencies. We also make our code for all of these computations publicly available.

description: We consider the injection of a controlled charge from a normal metal into an edge state of the fractional quantum Hall effect, with a time-dependent voltage $V(t)$. Using perturbative calculations in the tunneling limit, and a chiral Luttinger liquid model for the edge state, we show that the electronic correlations prevent the charge fluctuations to be divergent for a generic voltage pulse $V(t)$. This is in strong contrast with the case of charge injection in a normal metal, where this divergence is present. We show that explicit formul{ae} for the mean injected charge and its fluctuations can be obtained using an adiabatic approximation, and that non perturbative results can be obtained for injection in an edge state of the FQHE with filling factor $ nu=1/3$. Generalization to other correlated systems which can be described with the Luttinger liquid model, like metallic Carbon nanotube, is given.

description: Excerpts from the report Summary: The labor necessary for packaging and displaying meats in retail food stores that have self-service meat markets accounted for more than half of the total man-hour requirements in the markets studied. Motion and time study techniques were used to measure productivity of these functions as they were performed. An attempt was then made to increase productivity in each operation through the development of improved handling methods, equipment, and layouts in the meat departments. The application of selected improvements, in methods, materials, and equipment, to the packaging and displaying of meats in two typical self-service stores increased the productivity of these operations 10 and 23 percent respectively, in these stores and effected a saving of 10.6 and 31.2 man-hours per week, respectively. In addition, materials costs were reduced $19.08 and $10.20 per week in the two stores studied.

description: The article proves first that the constant quality factor (Q) contours for passive circuits, while represented on a 2D Smith chart, form circle arcs on a coaxal circle family. Furthermore, these circle arcs represent semi-circles families in the north hemisphere while represented on a 3D Smith chart. On the contrary we show that the constant Q contours for active circuits with negative resistance form complementary circle arcs on the same family of coaxal circles in the exterior of the 2D Smith chart. Also, we find out that these constant Q contours represent complementary semi-circles in the south hemisphere while represented on the 3D Smith chart for negative resistance circuits. The constant Q - computer aided design (CAD) implementation of the Q semi-circles on the 3D Smith chart is then successfully used to evaluate the quality factor variations of newly fabricated Vanadium dioxide inductors first, directly from their reflection coefficient, as the temperature is increased from room temperature to 50 degrees Celsius (°C). Thus, a direct multi-parameter frequency dependent analysis is proposed including Q, inductance and reflection coefficient for inductors. Then, quality factor direct analysis is used for two tunnel diode small signal equivalent circuits analysis, allowing for the first time the Q and input impedance direct analysis on Smith chart representation of a circuit, including negative resistance

description: We find an explicit relation between the two known ways of generating an infinite set of local conserved charges for the string sigma model on AdS_5 x S^5: the Backlund and monodromy approaches. We start by constructing the two-parameter family of Backlund transformations for the string with an arbitrary world-sheet metric. We then show that only for a special value of one of the parameters the solutions generated by this transformation are compatible with the Virasoro constraints. By solving the Backlund equations in a non-perturbative fashion, we finally show that the generating functional of the Backlund conservation laws is equal to a certain sum of the quasi-momenta. The positions of the quasi-momenta in the complex spectral plane are uniquely determined by the real parameter of the Backlund transform.

description: China is the world's largest producer and consumer of food. In the past, China's governmental policy advocated regional self-sufficiency in agricultural production, and it is generally believed that regional self-sufficiency was enforced at high economic cost. However, this changed with the 1979 economic reforms which encouraged some regional specialization. It is expected that there may be further shifts in regional production patterns and interregional trade flows. This article uses data on land productivity to test for regional comparative advantage, and it provides some empirical evidence on provincial comparative advantage in cotton versus grain production in China.

Schmidt introduced the M\_3[D] construction, an extension of the ﬁve-element nondistributive lattice M\_3 by a bounded distributive lattice D, deﬁned as the lattice of all triples $(x, y, z) \in D^3$ satisfying $x \mm y = x \mm z = y \mm z$. The lattice M\_3[D] is a modular congruence-preserving extension of D. In this paper, we investigate this construction for an arbitrary lattice L. For every n > 0, we exhibit an identity Un such that U1 is modularity and Un+1 is properly weaker than Un. Let Mn denote the variety deﬁned by Un, the variety of n-modular lattices. If L is n-modular, then M\_3[L] is a lattice, in fact, a congruence-preserving extension of L; we also prove that, in this case, $IdM\_3[L] \cong M\_3[Id L]$. We provide an example of a lattice L such that M\_3[L] is not a lattice. This example also provides a negative solution to a problem of R. W. Quackenbush: Is the tensor product $A\otimes B$ of two lattices A and B with zero always a lattice. We complement this result by generalizing the M\_3[L] construction to an M\_4[L] construction. This yields, in particular, a bounded modular lattice L such that $M\_4 \otimes L$ is not a lattice, thus providing a negative solution to Quackenbush's problem in the variety M of modular lattices. Finally, we sharpen a result of R. P. Dilworth: Every ﬁnite distributive lattice can be represented as the congruence lattice of a ﬁnite 3-modular lattice. We do this by verifying that a construction of G. Grätzer, H. Lakser, and E. T. Schmidt yields a 3-modular lattice.

description: Firm-level simulation is used to analyze farm financial performance with adjustable-rate, adjustable-term, and fixed-rate financing. Adjustable-term financing is accomplished by changing the term of the loan, instead of payment size, when interest rates change. Simulation results indicate that the adjustable-term loan is an innovation which reduces the cash flow destabilizing effects of volatile interest rates.

description: An econometric framework for estimating a two-regime dairy structural system is presented. Failure to account for switching between regimes due to government price intervention raises the problem of selectivity bias. Further, since a structural system of equations is involved, the problem is not limited to the market associated with the intervention. Rather, bias from a single source can distort all equations in the system. The ramifications of not correcting for the bias in policy analyses are investigated.

description: Excerpts from the report Foreword: Under present marketing methods, most agricultural products are graded, sorted, or divided into groups in producing areas in order to channel each type of product into its best market or use. These sorting or grading operations require a great deal of labor, which is often difficult to recruit during the harvest season and is becoming increasingly costly. This study was made to determine some principles which, if applied, would reduce the labor requirements for grading without impairing inspection efficiency. The principles developed in this study are based on tests with cylinders, ellipsoids, and spheroids. As the laboratory specimens used more nearly simulate certain fruits and vegetables than many other products, the data obtained are likely to be most applicable to such commodities. The principles developed, however, appear to be applicable to smaller agricultural products, such as tree nuts, and some other products that are conveyed or moved on tables or belts past graders.

description: We investigate properties of exponential operators preserving the particle number using combinatorial methods developed in order to solve the boson normal ordering problem. In particular, we apply generalized Dobinski relations and methods of multivariate Bell polynomials which enable us to understand the meaning of perturbation-like expansions of exponential operators. Such expansions, obtained as formal power series, are everywhere divergent but the Pade summation method is shown to give results which very well agree with exact solutions got for simplified quantum models of the one mode bosonic systems.

description: In this paper, we give the spectral energy distributions of 42 M81 globular clusters in 13 intermediate-band filters from 4000 to 10000 A, using the CCD images of M81 observed as part of the BATC multicolor survey of the Sky. The BATC multicolor filter system is specifically designed to exclude most of the bright and variable night-sky emission lines including the OH forest. Hence, it can present accurate SEDs of the observed objects. These spectral energy distributions are low-resolution spectra, and can reflect the stellar populations of the globular clusters. This paper confirms the conclusions of Schroder et al. that, M81 contains clusters as young as a few Gyrs, which also were observed in both M31 and M33

description: The number of cattle sold through video auctions has increased dramatically during the past five years. In this study structural differences in pricing between a group of traditional auctions and the nation's largest satellite video cattle auction are examined. A Chow test for structural pricing differences reveals that the influence of lot characteristics, market information, and merchandising strategies on cattle prices are essentially identical at both types of auctions. However, optimal lot size is larger at video auctions than at traditional auctions.

description: We have analyzed the interaction of a dissipative two level quantum system with high and low frequency excitation. The system is continuously and simultaneously irradiated by these two waves. If the frequency of the first signal is close to the level separation the response of the system exhibits undamped low frequency oscillations whose amplitude has a clear resonance at the Rabi frequency with the width being dependent on the damping rates of the system. The method can be useful for low frequency Rabi spectroscopy in various physical systems which are described by a two level Hamiltonian, such as nuclei spins in NMR, double well quantum dots, superconducting flux and charge qubits, etc. As the examples, the application of the method to a nuclear spin and to the readout of a flux qubit are briefly discussed.

description: The study uses primary data collected from a survey conducted in Georgia to analyze consumer preferences for testing and certification of fresh produce and consumers' willingness to pay for fresh produce that is certified as free of pesticide residues (FPR). An ordered probit model was estimated to identify the impacts of various exogenous variables on the probability of consumers' willingness to pay for a number of alternative price premiums. The results indicate that consumers' willingness to pay differs with respect to a number of factors. The study concludes that most of the consumers recommend testing and certification, but they oppose large price markups for certified-FPR fresh produce.

description: We present a mesoscale kinetic model for multicomponent flows, augmented with a short range forcing term, aimed at describing the combined effect of surface tension and near-contact interactions operating at the fluid interface level. Such mesoscale approach is shown to i) accurately capture the complex dynamics of bouncing colliding droplets for different values of the main governing parameters, ii) predict quantitatively the effective viscosity of dense emulsions in micro-channels and iii) simulate the formation of the so-called soft flowing crystals in microfluidic focusers.

description: Let $A$, $B$, and $S$ be (v,0)-semilattices and let $f: A\to B$ be a (v,0)-embedding. Then the canonical map, $f \otimes \id\_S$, of the tensor product $A \otimes S$ into the tensor product $B \otimes S$ is not necessarily an embedding. The (v,0)-semilattice $S$ is flat, if for every embedding $f : A\to B$, the canonical map $f\otimes\id$ is an embedding. We prove that a (v,0)-semilattice $S$ is flat if and only if it is distributive.

description: When a proprietor's liability is limited, borrowing behavior for an expected utility maximizer may vary widely. Proprietors with little to lose may rationally choose very large debt levels while others may choose to finance with 100% equity. This article presents a theory to explain these widely observed variations in behavior.
