description: This paper examines the impact of domestic and foreign macroeconomic variables on U.S. meat exports, including beef, pork, turkey, and chicken, in the context of an open economy. The results show that foreign macroeconomic variables exert more significant and persistent effects on U.S. meat exports than domestic macroeconomic variables. The implication is that the U.S. can increase its meat exports more effectively by expending efforts on international macroeconomic policy coordination rather than on domestic sectoral policy. The results also suggest that macroeconomic models of the agricultural sector should include foreign variables and should not be limited only to domestic ones.

description: Centralized, off-farm compost facilities were evaluated as a disposal option for poultry litter. Disposal fees to growers were required to develop an economically feasible facility for a private investor. The potential for a compost facility to compete with current litter alternatives depends upon development of compost markets comparable to urban areas along with a depressed market price for litter. Given disposal fees and uncertainty associated with market development, further expansion of land application and cattle feeding disposal alternatives is recommended.

description: Strong correlations within a symmetry-unbroken ground-state wavefunction can show up in approximate density functional theory as symmetry-broken spin-densities or total densities, which are sometimes observable. They can arise from soft modes of fluctuations (sometimes collective excitations) such as spin-density or charge-density waves at non-zero wavevector. In this sense, an approximate density functional for exchange and correlation that breaks symmetry can be more revealing (albeit less accurate) than an exact functional that does not. The examples discussed here include the stretched H$_2$ molecule, antiferromagnetic solids, and the static charge-density wave/Wigner crystal phase of a low-density jellium. It is shown that (and in what sense) the static charge density wave is a soft plasmon.

description: This paper examines the impact of PST on the optimal production/marketing decisions of a grow-finish hog farm operation. The analysis evaluates PST from three angles: the feed efficiency effect, the leaner meat price effect, and the aggregate-supply-induced price effect. When limited to the feed efficiency effect only, the primary response to the new technology is to increase the animal turnover rate of the operation. When the leaner meat price effect is also included, marketing weight increases while turnover rate remains relatively unchanged. Additionally, if the increased aggregate supply depressed the market price by more than 10%, the benefits from improved feed efficiency and learner meat will be completely dissipated. Aggregate price adjustments (reductions) of less than 10 percent maintained positive producer benefits resulting from improved feed efficiency and leaner meat.

description: We have studied spacetime structures of static solutions in the $n$-dimensional Einstein-Gauss-Bonnet-Maxwell-$Λ$ system. Especially we focus on effects of the Maxwell charge. We assume that the Gauss-Bonnet coefficient $α$ is non-negative and $4{\tilde α}/\ell^2\leq 1$ in order to define the relevant vacuum state. Solutions have the $(n-2)$-dimensional Euclidean sub-manifold whose curvature is $k=1,~0$, or -1. In Gauss-Bonnet gravity, solutions are classified into plus and minus branches. In the plus branch all solutions have the same asymptotic structure as those in general relativity with a negative cosmological constant. The charge affects a central region of the spacetime. A branch singularity appears at the finite radius $r=r_b>0$ for any mass parameter. There the Kretschmann invariant behaves as $O((r-r_b)^{-3})$, which is much milder than divergent behavior of the central singularity in general relativity $O(r^{-4(n-2)})$. Some charged black hole solutions have no inner horizon in Gauss-Bonnet gravity. Although there is a maximum mass for black hole solutions in the plus branch for $k=-1$ in the neutral case, no such maximum exists in the charged case. The solutions in the plus branch with $k=-1$ and $n\geq6$ have an "inner" black hole, and inner and the "outer" black hole horizons. Considering the evolution of black holes, we briefly discuss a classical discontinuous transition from one black hole spacetime to another.

description: This paper examines the economic impact of selected farmland characteristics on the appraised value of development rights. Price elasticities are estimated for the size and location of farmland parcels, the amount of road frontage, the existence of panoramic views, and the distance to urban centers. Estimated elasticities suggest that parcel characteristics have a substantial impact on the cost of preserving farmland. For example, the per-acre cost of development rights is estimated to be 53 percent higher on farmland parcels that have a panoramic view of water than on parcels that have no water view. Similarly, the per-acre cost of development rights on a typical 25-acre farm is estimated to be 90 percent higher than on a typical 150-acre farm. Results suggest that the net social benefits obtained through farmland preservation programs may be enhanced by considering the impact of farmland characteristics on the marginal costs of purchasing development rights, when selecting among a set of candidate farms.

description: Point base registration is an important part in many machine VISIOn applications, medical diagnostics, agricultural studies etc. The goal of point set registration is to find correspondences between different data sets and estimate the appropriate transformation that can map one set to another. Here we introduce a novel method for matching of different data sets based on Laplacian distribution. We consider the alignment of two point sets as probability density estimation problem. By using maximum likelihood methods we try to fit the Laplacian mixture model (LMM) centroids (source point set) to the data point set.

description: By identifying the Higgs field as an internal component of a higher dimensional gauge field it is possible to solve the little hierarchy problem. The construction of a realistic model that incorporates such a gauge-Higgs unification is an important problem that demands attention. In fact, several attempts in this direction have already been put forward. In this letter we single out one such attempt, a 6D SU(3) extended electroweak theory, where it is possible to obtain a Higgs mass prediction in accord with global fits. One shortcoming of the model is its prediction for the Weinberg angle, it is too large. We slightly modify the model by including brane kinetic terms in a way motivated by the orbifold action on the 6D fields. We show that in this way it is possible to obtain the correct Weinberg angle while keeping the desired results in the Higgs sector.

description: Under certain conditions, a transparent photonic band can be designed into a one-dimensional metallodielectric nanofilm structure. Unlike conventional pass bands in photonic crystals, where the finite thickness of the structure affects the transmission of electromagnetic fields having frequency within the pass band, the properties of the transparent band are almost unaffected by the finite thickness of the structure. In other words, an incident field at a frequency within the transparent band exhibits 100% transmission independent of the number of periods of the structure. The transparent photonic band corresponds to excitation of pure eigenstate modes across the entire Bloch band in structures possessing mirror symmetry. The conditions to create these modes and thereby to lead to a totally transparent band phenomenon are discussed.

Cnj : subtitle a visual programming environment for constraint nets

Publisher: name: University of British Columbia
Year: 2009

description: The Constraint Nets model (CN) proves to be useful for a wide variety of purposes, ranging from intelligent agent systems, and real-time embedded systems, to integrated hybrid systems with various time structures: discrete, continuous, and time-based. This thesis describes a new visual programming environment called CNJ (Constraint Nets in Java) which utilizes component-based technology. CNJ uses JavaBeans, Bean Introspection, drag-and-drop, and Java Swing MDI (Multiple Document Interface) technologies, as well as XML-based CNML as its standard interchange format. The environment supports constraint net modeling, simulation, and animation for hybrid systems. Furthermore, it provides support for a topdown design, middle-out design, and bottom-up design where the module bean can be reused anywhere in any other CN model, saving designers time and effort. As an experiment, a hybrid dynamic elevator system is developed successfully, and test results confirm the effectiveness of the tool for hybrid system modeling and real-time simulation.

description: A dynamic model of the U.S. apple industry, including relationships for bearing acres, production, utilization, and allocation to the fresh, canned, frozen, juice, dried and other markets, is specified. Demands for each of these markets are modeled. Model coefficients are obtained using Zellner's seemingly unrelated regression procedure and data from 1971 through 1990. Elasticities and flexibilities are compared with other studies. Projections indicate that price fluctuations will continue in the industry when acreage is held at 1990 levels. A ten percent increase in fresh exports strengthens all apple prices. However, a ten percent decrease in the price of juice imports mitigates some of this effect.

description: Photon helicity-dependent photocurrent is measured at zero magnetic field on a device based on an ensemble of InGaAs/GaAs quantum dots that are embedded into a GaAs-based p-i-n diode. Our main goal is to take advantage of the long electron spin relaxation time expected in these nano-objects. In these experiments, no external magnetic field is required thanks to the use of an ultrathin magnetic CoFeB/MgO electrode, presenting perpendicular magnetic anisotropy (PMA). We observe a clear asymmetry of the photocurrent measured under respective right and left polarized light that follows the hysteresis of the magnetic layer. The amplitude of this asymmetry at zero magnetic field decreases with increasing temperatures and can be controlled with the bias. Polarization-resolved photoluminescence is detected in parallel while the device is operated as a photodetector. This demonstrates the multifunctional capabilities of the device and gives valuable insights into the spin relaxation of the electrons in the quantum dots.

description: The region around PSR B1706-44 has been observed with the H.E.S.S. imaging atmospheric Cherenkov telescopes in 2003. No evidence for gamma-ray emission in the TeV range was found at the pulsar position or at the radio arc which corresponds to the supernova remnant G 343.1-2.3. The 99% confidence level flux upper limit at the pulsar position is Ful(E > 350GeV) = 1.4e-12 /cm^2/s assuming a power law with photon index of 2.5 and Ful(E > 500GeV) = 1.3e-12 /cm^2/s without an assumption on the spectral shape. The reported upper limits correspond to 8% of the flux from an earlier detection by the CANGAROO experiment.

description: The volatile composition of a planet is determined by the inventory of gas and ice in the parent disk. The volatile chemistry in the disk is expected to evolve over time, though this evolution is poorly constrained observationally. We present ALMA observations of C18O, C2H, and the isotopologues H13CN, HC15N, and DCN towards five Class 0/I disk candidates. Combined with a sample of fourteen Class II disks presented in Bergner et al. (2019b), this data set offers a view of volatile chemical evolution over the disk lifetime. Our estimates of C18O abundances are consistent with a rapid depletion of CO in the first ~0.5-1 Myr of the disk lifetime. We do not see evidence that C2H and HCN formation are enhanced by CO depletion, possibly because the gas is already quite under-abundant in CO. Further CO depletion may actually hinder their production by limiting the gas-phase carbon supply. The embedded sources show several chemical differences compared to the Class II stage, which seem to arise from shielding of radiation by the envelope (impacting C2H formation and HC15N fractionation) and sublimation of ices from infalling material (impacting HCN and C18O abundances). Such chemical differences between Class 0/I and Class II sources may affect the volatile composition of planet-forming material at different stages in the disk lifetime.

description: We present broad band photometry and spectroscopic observations of the host galaxy of GRB 030329. Analysis of the spectral emission lines shows that the host is likely a low metallicity galaxy (Z~0.004). The spectral energy distribution (SED) constructed with the photometric points has been fitted using synthetic and observational templates. The best SED fit is obtained with a starburst template with an age of ~150 Myr and an extinction Av~0.6. We find that the GRB 030329 host galaxy is a subluminous galaxy (L~0.016 L*) with a stellar mass of >~10^8 Mo. Three independent diagnostics, based on the restframe UV continuum, the [OII], and the Balmer emission lines, provide a consistent unextincted star formation rate of ~0.6 Mo yr^-1, implying a high unextincted specific star formation rate (~34 Mo yr^-1 (L/L*)^-1). We estimate that the unextincted specific star formation rate of the GRB 030329 host is higher than ~93.5% of the galaxies at a similar redshift.

description: We propose an alternative theoretical approach showing how the existence of an extra dimension in Randall-Sundrum model can estimate the correction in the horizon of Schwarzschild and Kerr black holes, and consequently its measurability in terms of the variation of quasar luminosity, which can be caused by a imprint of an extra dimension endowing the geometry of a brane-world scenario in an AdS5 bulk. The rotation effects cause a more prominent correction in Kerr horizon radius than in Schwarzschild (static black hole) radius, via brane-world effects, and the consequent bigger variation in the luminosity in Kerr black holes quasars. This paper is intended to investigate the variation of luminosity due to accretion of gas in Schwarzschild and Kerr black holes (BHs) in the center of quasars, besides also investigating the variation of luminosity in supermassive BHs by brane-world effects, using Randall-Sundrum model.

description: To help prevent motor vehicle accidents, there has been significant interest in finding an automated method to recognize signs of driver distraction, such as talking to passengers, fixing hair and makeup, eating and drinking, and using a mobile phone. In this paper, we present an automated supervised learning method called Drive-Net for driver distraction detection. Drive-Net uses a combination of a convolutional neural network (CNN) and a random decision forest for classifying images of a driver. We compare the performance of our proposed Drive-Net to two other popular machine-learning approaches: a recurrent neural network (RNN), and a multi-layer perceptron (MLP). We test the methods on a publicly available database of images acquired under a controlled environment containing about 22425 images manually annotated by an expert. Results show that Drive-Net achieves a detection accuracy of 95%, which is 2% more than the best results obtained on the same database using other methods

description: In this paper, I presented a thorough analysis of various discourse features and their application to a course book material and authentic text. Following the analysis, I emphasized the implications of both materials on learners’ language acquisition. I believe that in order to achieve the desired outcome in language acquisition, some level of authenticity should be involved in the materials used in language classrooms. This will allow learners to build sufficient understanding of the authentic discourse features of the language acquired. However, structure is also needed to establish a well-rounded path for learners. Finally, the teacher, who is the ultimate provider of information in the classroom, should also obtain a profound understanding of the needs and expectations of the learners. This will not only help learners to study in a more relaxed environment but also minimize the linguistic difficulties they face and prevent potential cultural misunderstandings.

Risk and Uncertainty

description: This paper presents a model of the farm labor allocation decision based on risk and return characteristics of different activities. It is shown that off-farm employment can play an important role in the diversification of farm family income, implying that portfolio models of risk and return to farm activities should take into account the possibility of off-farm employment. A model of the labor allocation decision based on the risk and return characteristics of each activity is developed and tested using a state level cross section of the United States over the post-war period, and performs well in explaining variation in reliance on off-farm income.

description: The empirical evidence from the extant literature in demand analysis points to the importance of income in food expenditure relationships. However, roughly 30 percent of all households in the 1977-78 Nationwide Food Consumption Survey do not report income figures. The focus of this paper is on the missing income problem in analyses of Engel functions. This analysis statistically links particular demographic attributes in affecting the probability of reporting income information. Additionally, several techniques to overcome the missing income problem, namely, regression imputation, the Heckman procedure, and item deletion, are discussed. Empirical evidence suggests that the Heckman procedure is statistically superior to item deletion, and that regression imputation and the Heckman procedure yield similar results.

description: We employed accurate full potential density-functional theory and linearized augmented plane wave method to investigate the electronic properties and possible phase transitions of Cu3N under high pressure. The anti perovskite structure Cu3N is a semiconductor with a small indirect band gap at ambient pressure. The band gap becomes narrower with increasing pressure, and the semi-conducting anti ReO3 structure undergoes a semiconductor to semimetal transition at pressure around 8.0 GPa. At higher pressure, a subsequent semimetal to metal transition could take place above 15GPa with a structural transition from anti ReO3 to Cu3Au structure.

description: Increased consumer health concerns over ingestion of animal fats have spawned consumer research regarding effects of different degrees of leanness (marbling levels) on consumer demand. Previous research is reviewed and a recent multi-city consumer panel test is reported. Implications of the multi-city results are discussed from the viewpoint of applicability of normative consumer behavior demand theory, and implications of the findings for beef marketing structure and strategies. Suggestions for consumer panel research designs are also implied. Expert laboratory, consumer laboratory, and household panels were employed.
mmRAPID: Machine Learning assisted Noncoherent Compressive Millimeter-Wave Beam Alignment

description: Millimeter-wave communication has the potential to deliver orders of magnitude increases in mobile data rates. A key design challenge is to enable rapid beam alignment with phased arrays. Traditional millimeter-wave systems require a high beam alignment overhead, typically an exhaustive beam sweep, to find the beam direction with the highest beamforming gain. Compressive sensing is a promising framework to accelerate beam alignment. However, model mismatch from practical array hardware impairments poses a challenge to its implementation. In this work, we introduce a neural network assisted compressive beam alignment method that uses noncoherent received signal strength measured by a small number of pseudorandom sounding beams to infer the optimal beam steering direction. We experimentally showcase our proposed approach with a 60GHz 36-element phased array in a suburban line-of-sight environment. The results show that our approach achieves post alignment beamforming gain within 1dB margin compared to an exhaustive search with 90.2 percent overhead reduction. Compared to purely model-based noncoherent compressive beam alignment, our method has 75 percent overhead reduction.

description: We report the results on factors for self-protective behavior against weather extremes such as extreme heat events, drought, and heavy precipitation. Our research draws on the Model of Private Proactive Adaptation to Climate Change (MPPACC). We developed a survey instrument incorporating the main aspects of the MPPACC and other factors from related research work that are assumed to explain why some people show self-protective behavior while others do not. The interview survey was conducted with a non-random sample of 210 respondents from three Philippine cities, namely Baguio, Dagupan, and Tuguegarao. The results reveal the importance of adaptation appraisal, including the perceived feasibility of self-protective measures, the perceived adaptation knowledge, and, with limitations, the perception of actions taken by neighbors or friends. We also show that perceptions of past weather trends are closely linked to risk perception but are only partly corroborated by weather station data. Implications for fostering self-protective behavior are making use of time windows right after an extreme weather event and focusing on enhancing adaptation appraisal.

The extremely asymmetric radio structure of the z=3.1 radio galaxy B3 J2330+3927

description: We report on 1.7 and 5.0 GHz observations of the z=3.087 radio galaxy B3 J2330+3927, using the Very Long Baseline Array (VLBA), and archival 1.4 and 8.4 GHz Very Large Array (VLA) data. Our VLBA data identify a compact, flat spectrum (α_{1.7 GHz}^{5 GHz} = -0.2 +/- 0.1; S_ν~ ν^α) radio component as the core. The VLA images show that the fraction of core emission is very large (f_c \approx 0.5 at 8.4 GHz), and reveal a previously undetected, very faint counterjet, implying a radio lobe flux density ratio R >= 11 and a radio lobe distance ratio Q \approx 1.9. Those values are much more common in quasars than in radio galaxies, but the optical/near-IR spectra show a clear type II AGN for B3 J2330+3927, confirming that it is indeed a radio galaxy. Unlike all other radio galaxies, the bright Ly-αemitting gas is located towards the furthest radio arm. We argue against environmental and relativistic beaming effects being the cause of the observed asymmetry, and suggest this source has intrinsically asymmetric radio jets. If this is the case, B3 J2330+3927 is the first example of such a source at high redshift, and seems to be difficult to reconcile with the unified model, which explains the differences between quasars and radio galaxies as being due to orientation effects.

description: This paper argues that the use of "laboratory" data sets can add substantially to the teaching of production economics at the graduate level. Optimal experimental designs for generating pseudo data from a process model are discussed. These are shown to depend of the functional form to be estimated. We choose the translog form for our multiproduct profit function and compare alternative approaches to estimation, using pseudo data from a farm-level linear programming model. Particular restrictions on this profit function are also considered. Finally, aggregation of output prices is shown to alter substantially input price elasticities of demand.

Tsirelson bounds for generalized Clauser-Horne-Shimony-Holt inequalities
Creators: name: Wehner, Stephanie
Publisher: name: arXiv
Year: 2005
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Quantum theory imposes a strict limit on the strength of non-local correlations. It only allows for a violation of the CHSH inequality up to the value 2 sqrt(2), known as Tsirelson's bound. In this note, we consider generalized CHSH inequalities based on many measurement settings with two possible measurement outcomes each. We demonstrate how to prove Tsirelson bounds for any such generalized CHSH inequality using semidefinite programming. As an example, we show that for any shared entangled state and observables X_1,...,X_n and Y_1,...,Y_n with eigenvalues +/- 1 we have | + + + + ... + - | <= 2 n cos(pi/(2n)). It is well known that there exist observables such that equality can be achieved. However, we show that these are indeed optimal. Our approach can easily be generalized to other inequalities for such observables.

Adaptive support for student learning in educational games
Creators: name: Zhao, Xiaohong
Publisher: name: University of British Columbia
Year: 2009

description: Educational games can be highly entertaining, but studies have shown that they are not always effective for learning. To enhance the effectiveness of educational games, we propose intelligent pedagogical agents that can provide individualized instruction that is integrated with the entertaining nature of these systems. We embedded one such animated pedagogical agent into the electronic educational game Prime Climb. To allow the agent to provide individualized help to students, we built a probabilistic student model that performs on-line assessment of student knowledge. To perform knowledge assessment, the student model accesses a student's game actions. By representing the probabilistic relations between these actions and the corresponding student's knowledge in a Bayesian Network, the student model assesses the evolution of this knowledge during game playing. We performed an empirical study to test the effectiveness of both the student model and the pedagogical agent. The results of the study strongly support the effectiveness of our approach.

description: Combining the effects of fluxes and gaugino condensation in heterotic supergravity, we use a ten-dimensional approach to find a new class of four-dimensional supersymmetric AdS compactifications on almost-Hermitian manifolds of SU(3) structure. Computation of the torsion allows a classification of the internal geometry, which for a particular combination of fluxes and condensate, is nearly Kahler. We argue that all moduli are fixed, and we show that the Kahler potential and superpotential proposed in the literature yield the correct AdS radius. In the nearly Kahler case, we are able to solve the H Bianchi using a nonstandard embedding. Finally, we point out subtleties in deriving the effective superpotential and understanding the heterotic supergravity in the presence of a gaugino condensate.

description: Irrigation with saline waters is a major problem in many parts of the world. Economic questions have usually been addressed using synthesized production functions and theoretically based soil salinity relations. The purpose of this paper is to estimate functions relating crop yield and salt accumulation in the soil to initial soil salinity and water quantity and quality. Crop response functions and dynamic salt balance relations are estimated from experimental data for alfalfa and cotton. The estimated functions are then used in a dynamic programming model to determine optimal water applications for different levels of initial soil salinity and crop and water prices.

description: Slovak sectoral partial equilibrium econometric model based on AG-MEMOD approach is used to analyse the development of the selected Slovak agricultural markets after EU accession. Simulation results for cereals and meats are provided in this poster. Two scenarios are analysed: non-accession baseline and accession with adoption of single area payment scheme. EU accession is expected to increase prices of most products, the biggest increase of prices will occur in animal sector. Because of higher prices consumption will go down. Decrease of consumption will be mitigated by income growth. Production will not increase substantially due to decoupling of direct payments. Trade balance for majority of products will improve.
