description: This research proposes the estimation of a partial equilibrium econometric and simulation international trade model for sorghum: United States and Mexico component. Sixteen equations were simultaneously estimated and validated as a system using seemingly unrelated regression. Results on parameter estimates agree with economic theory and a working model for simulation and forecast was obtained. Forecast scenarios suggest that the dependency of sorghum trade between US and Mexico will continue.
Time Extended Measurement of the Position of a Particle

description: The von Neumann interaction between a particle and an apparatus has been considered in the measurement of the position of a particle when the interaction lasts for a finite amount of time. When the measurement has finite duration, both the motion of the pointer and the particle influence the result of the measurement. Provided that the particle is in an eigenstate of its position at the start of the measurement, the pointer will indicate the arithmetic average between the initial and final position of the particle. Furthermore, the probability that the pointer will indicate a given average value is equal to the transition probability for the undisturbed particle to experience the change in position. If the initial state of the pointer is a narrow wavepacket, then for any initial state of the particle, the measurement yields, approximately, the undisturbed probability distribution for the position of the particle at the end of the measurement.

description: Economic Simulation model (SIMETAR) was used to investigate the effect of future corn price on profitability of control and phytase enhanced diet of hogs. The completed simulation model was used to estimate probability distribution for control vs lower excretion diet profitability under different corn prices. Data used was collected from recent field trials in Oklahoma that tested the effect of phytase enhanced diets on reducing phosphorus emission. The results showed that as the market price of corn increases control diet will be more profitable than phytase enhanced diet, given the cost of other remaining feed ingredient is constant for both the diets.

description: Deconstruction is a powerful means to explore the rich dynamics of gauge theories in four and higher dimensions. We demonstrate that gauge symmetry breaking in a compactified higher dimensional theory can be formulated via deconstructed 4D moose theory with {\it spontaneous symmetry breaking} and {\it without boundary condition.} The proper higher-D boundary conditions are automatically induced in the continuum limit rather than being imposed. We identify and analyze the moose theories which exhibit {\it delayed unitarity violation} (effective unitarity) as a {\it collective effect} of many gauge groups, without resorting to any known 5D geometry. Relevant phenomenological constraints are also addressed.

description: In this work we present crystal structure determination of two elusive polymorphs of furazidin, an antibacterial agent, employing a combination of crystal structure prediction (CSP) calculations and NMR crystallography approach. Two previously uncharacterized neat crystal forms, one of which has two symmetry independent molecules (form I), whereas the other one has only one molecule (form II), crystallize in P21/c and P-1 space groups, respectively, and are both built by different conformers, displaying different intermolecular interactions. We demonstrate that the usage of either crystal structure prediction or NMR crystallography alone is insufficient to successfully elucidate the mentioned crystal structures, especially in the case with two independent molecules in the polymorph structure. In addition, cases of serendipitous agreement in terms of 1H or 13C NMR data obtained for the crystal structure prediction generated crystal structures different from the ones observed in laboratory (false-positive matches) are analyzed and described. Although for majority of analyzed crystal structures the obtained agreement with the NMR experiment is indicative of some structural features in common with the experimental structure, the mentioned serendipity observed in exceptional cases points to the necessity of caution when using NMR crystallography approach in crystal structure determination.

Logica dei sensi. Estetica e teoria della conoscenza in Benedetto Croce
Creators: name: Peluso, Rosalia
Publisher: name: Aisthesis. Pratiche, linguaggi e saperi dell’estetico
Year: 2017

description: This essay offers a general interpretation of Benedetto Croce’s aesthetics as a theory of knowledge. It takes its title from Croce’s famous work in the 1931, Le Due Scienze Mondane; l’Estetica e l’Economica, in which Croce describes the process of development of modern aesthetics as the affirmation of a logica dei sensi (logic of senses); a definition developed from the “poetic logic” in Vico’s Scienza Nuova. The essay starts with a comparison with Gilles Deleuze’s logic of sense, or thought of the surface, to propose the argument that Croce can be acknowledged as one of the authors of the Nietzschean reversal of Platonism. This argument is supported by the anti-metaphysical character of Croce’s thought, who has always pursued the aim of overcoming cognitive dualism (body and mind, external and internal, nature and spirit) to give new dignity to the sense in all of its complexity and, by consequence, to the world. Aesthetics, in Croce’s solution, possesses two philosophical meanings: because its better epistemological definition – particularly in the connection between intuition and expression – provides advantages in other fields of philosophy; in addition, aesthetics is the initial form of spiritual life.

description: Mobility and blockage are two critical challenges in wireless transmission over millimeter-wave (mmWave) and Terahertz (THz) bands. In this paper, we investigate network massive multiple-input multiple-output (MIMO) transmission for mmWave/THz downlink in the presence of mobility and blockage. Considering the mmWave/THz propagation characteristics, we first propose to apply per-beam synchronization for network massive MIMO to mitigate the channel Doppler and delay dispersion effects. Accordingly, we establish a transmission model. We then investigate network massive MIMO downlink transmission strategies with only the statistical channel state information (CSI) available at the base stations (BSs), formulating the strategy design problem as an optimization problem to maximize the network sum-rate. We show that the beam domain is favorable to perform transmission, and demonstrate that BSs can work individually when sending signals to user terminals. Based on these insights, the network massive MIMO precoding design is reduced to a network sum-rate maximization problem with respect to beam domain power allocation. By exploiting the sequential optimization method and random matrix theory, an iterative algorithm with guaranteed convergence performance is further proposed for beam domain power allocation. Numerical results reveal that the proposed network massive MIMO transmission approach with the statistical CSI can effectively alleviate the blockage effects and provide mobility enhancement over mmWave and THz bands.

description: Risk is an inevitable part of agricultural production and all producers face various forms of risk. This study used the subjective price expectations and price distributions of survey participants to determine how producer’s expectations compare with that of the market. Data used for this study were gathered through survey responses from Mississippi State University Extension meeting and workshop participants. Individual respondent’s discreet stated price and price distribution information was fitted to a continuous distribution and an implied mean and standard deviation was determined. This was compared to market price and price risk data. Participants largely over-estimated price. Individual volatilities resulting from each fitted distribution were lower than that implied by the market.

description: Pansharpening is to fuse a multispectral image (MSI) of low-spatial-resolution (LR) but rich spectral characteristics with a panchromatic image (PAN) of high-spatial-resolution (HR) but poor spectral characteristics. Traditional methods usually inject the extracted high-frequency details from PAN into the up-sampled MSI. Recent deep learning endeavors are mostly supervised assuming the HR MSI is available, which is unrealistic especially for satellite images. Nonetheless, these methods could not fully exploit the rich spectral characteristics in the MSI. Due to the wide existence of mixed pixels in satellite images where each pixel tends to cover more than one constituent material, pansharpening at the subpixel level becomes essential. In this paper, we propose an unsupervised pansharpening (UP) method in a deep-learning framework to address the above challenges based on the self-attention mechanism (SAM), referred to as UP-SAM. The contribution of this paper is three-fold. First, the self-attention mechanism is proposed where the spatial varying detail extraction and injection functions are estimated according to the attention representations indicating spectral characteristics of the MSI with sub-pixel accuracy. Second, such attention representations are derived from mixed pixels with the proposed stacked attention network powered with a stick-breaking structure to meet the physical constraints of mixed pixel formulations. Third, the detail extraction and injection functions are spatial varying based on the attention representations, which largely improves the reconstruction accuracy. Extensive experimental results demonstrate that the proposed approach is able to reconstruct sharper MSI of different types, with more details and less spectral distortion as compared to the state-of-the-art.

Smooth Formulation for Isothermal Compositional Simulation with Improved Nonlinear Convergence

description: Compositional simulation is challenging, because of highly nonlinear couplings between multi-component flow in porous media with thermodynamic phase behavior. The coupled nonlinear system is commonly solved by the fully-implicit scheme. Various compositional formulations have been proposed. However, severe convergence issues of Newton solvers can arise under the conventional formulations. Crossing phase boundaries produces kinks in discretized equations, and subsequently causing oscillations or even divergence of Newton iterations. The objective of this work is to develop a smooth formulation that removes all the property switches and discontinuities associated with phase changes. We show that it can be very difficult and costly to smooth the conservation equations directly. Therefore, we first reformulate the coupled system, so that the discontinuities are transferred to the phase equilibrium model. In this way a single and concise non-smooth equation is achieved and then a smoothing approximation can be made. The new formulation with a smoothing parameter provides smooth transitions of variables across all the phase regimes. In addition, we employ a continuation method where the solution progressively evolves toward the target system. We evaluate the efficiency of the new smooth formulation and the continuation method using several complex problems. Compared to the standard natural formulation, the developed formulation and method exhibit superior nonlinear convergence behaviors. The continuation method leads to smooth and stable iterative performance, with a negligible impact on solution accuracy. Moreover, it works robustly for a wide range of flow conditions without parameter tuning.

description: The utilization of short rotation woody crops (SRWC) to produce wood on marginal crop and pasture land could greatly enhance the production of wood for various uses in Minnesota with utilization for energy being of current interest. SRWC involves the more intensive application of inputs on more valuable land than naturally regenerated forests that currently supply the bulk of the forest products industry in Minnesota. Breeding efforts to improve productivity and disease resistance in hybrid poplar species are making the technology of SRWC competitive with agricultural uses of marginal land. This study models the economic impact of a potential shift in use of the land resource by replacing production of hay and pasture that provides feed for cow-calf beef operations in northwest and west central Minnesota with SRWC. Regional economic impacts of such a shift are measured with established input-output techniques, using the software tool IMPLAN. To complete this analysis, the magnitudes and sectors of expenditures needed to produce either beef calves or hybrid poplar plantations were compared using farm records and hybrid poplar budgets. Construction of a $175 million energy conversion facility capable of making 44 million gallons of ethanol and 7.6 million gallons of mixed alcohols by catalytic means following gasification would result in creation of 2,412 jobs during the construction period, with $158 million in value-added (mainly employee compensation and business taxes). Operation of the facility after the end of construction, if supported by 200,000 acres of hybrid poplar production, would not change the number of jobs very much compared with using the land for cow-calf operations. However, the SRWC-related jobs would likely be at higher average salary levels and business tax collections would be higher, for a value-added increase of $80 million annually. In addition to greater wood supplies to support the forest products industry, logging pressures may be reduced on public forest land as a consequence of greater deployment of technology and methods that can result in production per acre that is eight to ten-fold greater than naturally regenerated forests.

description: We calculate the electron-phonon scattering and binding in semiconducting carbon nanotubes, within a tight binding model. The mobility is derived using a multi-band Boltzmann treatment. At high fields, the dominant scattering is inter-band scattering by LO phonons corresponding to the corners K of the graphene Brillouin zone. The drift velocity saturates at approximately half the graphene Fermi velocity. The calculated mobility as a function of temperature, electric field, and nanotube chirality are well reproduced by a simple interpolation formula. Polaronic binding give a band-gap renormalization of ~70 meV, an order of magnitude larger than expected. Coherence lengths can be quite long but are strongly energy dependent.

description: Written in 1922, the present essay by Baeumler on the aesthetics of Croce belongs to the period of the German philosopher’s thought culminating with Das Irrationalitätproblem in der Ästhetik und Logik des 18. Jahrhunderts bis zur Kritik der Urteilskraft (1923), in which he works on a systematic project about a “logic of individuality”. This concept, which appears in the western world with the birth of modern aesthetics, when the notion of “judgment of taste” established itself in the third Critique by Kant, will find in Croce, during the twentieth century, one of the most attentive Philosophers to the problem it implies.

Two shape coexistence, one in the ground state of 104 Nb between oblate and triaxial shapes and another one between oblate and rarely seen prolate non-collective shapes in excited hot rotating 100 Nb at the mid spin values around 14-16h are reported for the first time. The level density parameter indicates the influence of the shell effects and changes drastically at the shape transition. The band crossing is observed at the sharp shape transition.

description: Molecular quantum mechanics (MQM) investigations have been performed for elucidation of fundamental principles of the photo-induced water oxidation in oxygen evolving complex (OEC) of photosystem II (PSII). To this end, as a first theoretical step, broken symmetry (BS) quantum mechanics (QM) and QM(BS)/molecular mechanics (MM) calculations have been conducted for elucidation of geometrical, electronic and spin structures of the CaMn4Ox (X = 5, 6) cluster in the five steps Si (i = 0∼4) of the Kok cycle for water oxidation. The QM and QM/MM calculations have provided full optimised geometries of short-lived key intermediates and transition state structure for the O-O bond formation in the native solar-energy conversion. The interplay between theory and experiment have clearly indicated that the CaMn4O5 cluster in OEC of PSII exhibits typical physicochemical properties of strong correlation electron system (SCES) confined with effective protein field. Our QM and QM/MM computational results for key intermediates and transition structure for the O-O bond formation in the Kok cycle are now plentiful for derivation of fundamental principles (FP) for understanding of photo-induced water oxidation in OEC of PSII. We summarize twenty nine fundamental principles (FPs) in systematic manner by QM and QM/MM calculations for understanding of water oxidation in Oxygen Evolving Complex(OEC) of Photosystem II(PSII). One of our final aims is theoretical design of the next-generation artificial photosystem materials composed of abundant metal ions.

description: We demonstrate an optical frequency analysis method using the Fourier transform of detection times of fluorescence photons emitted from a single trapped 40Ca+ ion. The response of the detected photon rate to the relative laser frequency deviations is recorded within the slope of a dark resonance formed in the lambda-type energy level scheme corresponding to two optical dipole transitions. This approach enhances the sensitivity to the small frequency deviations and does so with reciprocal dependence on the fluorescence rate. The employed lasers are phase locked to an optical frequency comb, which allows for precise calibration of optical frequency analysis by deterministic modulation of the analyzed laser beam with respect to the reference beam. The attainable high signal-to-noise ratios of up to a MHz range of modulation deviations and up to a hundred kHz modulation frequencies promise the applicability of the presented results in a broad range of optical spectroscopic applications.

From tree patterns to generalized tree patterns : on efficient evaluation of XQuery
Creators: name: Chen, Zhimin
Publisher: name: University of British Columbia
Year: 2009

description: XQuery is the de facto standard XML query language, and it is important to have efficient query evaluation techniques available for it. It is a well-known fact that a formal bulk algebra is essential for efficient query evaluation, and the Tree Algebra for XML (TAX), among others, is invented for this purpose. It can be shown in this thesis that a substantial subset of XQuery can be expressed as TAX. An XML document is often modelled as an ordered label tree. A core operation in the evaluation of XQuery is the finding of matches for specified tree patterns against the data tree (or forest), and there has been much work towards algorithms for finding such matches efficiently. Multiple XPath expressions can be evaluated by computing one or more tree pattern matches. However, because of the flexibility of XML data, the efficient evaluation of XQuery queries as a whole is much more than a tree pattern match and combining matchings of multiple tree patterns is not the most efficient evaluation plan for XQuery. In this thesis a structure called generalized tree pattern (GTP) is proposed to concisely represent a whole XQuery expression. Evaluating a query reduces to finding the matches of its GTP, which leads to more efficient evaluation plans. Algorithms are developed to translate an XQuery expression, possibly involving join, quantifiers, grouping, aggregation and nesting, to its GTP, and to generate efficient physical plans for a specified GTP. XML data often conforms to a schema. Relevant constraints from the schema give rise to further opportunities to optimize queries. Algorithms are given in the thesis to automatically infer structural constraints from a given schema and to simplify a GTP given a set of structural constraints. Finally, a detailed set of experiments using the TIMBER XML database system shows that plans via GTPs (with or without schema knowledge) significantly outperform plans based on navigation and straightforward plans obtained directly from the query.

description: We present a numerical study about the confining regime of compact U(1) lattice gauge theory in 4D. To address the problem, we exploit the duality properties of the theory. The main features of this method are presented, and its possible advantages and limits with respect to alternative techniques are briefly discussed. In Monte Carlo simulations, we focus our attention onto the case when a pair of static external charges is present. Some results are shown, concerning different observables which are of interest in order to understand the confinement mechanism, like the profile of the electric field induced by the static charges, and the ratios between Polyakov loop correlation functions at different distances.

description: We study the evolution of charged droplets of a conducting viscous liquid. The flow is driven by electrostatic repulsion and capillarity. These droplets are known to be linearly unstable when the electric charge is above the Rayleigh critical value. Here we investigate the nonlinear evolution that develops after the linear regime. Using a boundary elements method, we find that a perturbed sphere with critical charge evolves into a fusiform shape with conical tips at time $t_0$, and that the velocity at the tips blows up as $(t_0-t)^α$, with $α$ close to -1/2. In the neighborhood of the singularity, the shape of the surface is self-similar, and the asymptotic angle of the tips is smaller than the opening angle in Taylor cones.

description: Nowadays, it has become a basic need to reuse existing Application Programming Interface (API), Class Libraries, and frameworks for rapid software development. Software developers often reuse this by calling the respective APIs or libraries. But in doing so, developers usually encounter different problems in searching for appropriate code snippets. In most cases, API and Libraries are complex and not well structured or well documented. Online search engine consumes time in searching, yet match is not that relevant and representation is not good. To get a suggestion according to the query we can find that snippet online using search engines or code search engines. In some cases database dependent searching and remote web server based mined repository searching bring a problem to the developers. Finding an API recommendation on code search engine often deal with extra-large files that eventually slow down the software development process. We have searched for a solution throughout our work and tried to bring a better outcome. As an alternative action, we have implemented a system what we call Enhancing Software Development Process (ESDP) tool that is able to provide an efficient and working integrated environment to the developers with a better abstraction and representation of the search results and programmers need to be derived from the source codes. We also have built and applied an XML based enriched repository to get a recommendation from the mined repository on the client-side without interacting with the internet-dependent server to save complications and times. We provide the most relevant code skeletons or mapping to programmers or developers using graph-based representation.

Energy dependence of strangeness production

description: We present a summary of strange particle yields measured by the experiment NA49 in central Pb+Pb collisions in the beam energy range 20-158 AGeV. The comparison with thermal hadron model results shows that above 30 AGeV, a strangeness undersaturation parameter gamma_S must be employed to describe the data. This suggests a change in the strangeness production mechanism at this energy. We find that the UrQMD transport model in all cases underpredicts the observed particle yields.

Hipposideridae

description: Hipposideridae
 There is some confusion as to how many species exist within the Hipposideros caffer-ruber complex; recently, Vallo et al. (2008) demonstrated seven lineages based on cytochrome b sequences. Of these, the A1 and B2 lineages could be geographically associated with the names of caffer (A1 lineage extending from South Africa to central Mozambique including the type locality Durban, South Africa) and ruber (B2 extending from Malawi to Kenya and Tanzania including the type locality Dar es Salaam), respectively. It is thus highly likely that the names caffer and ruber as used here are correctly applied, with the former occurring widely in Mozambique and the latter restricted to northern Mozambique (no records from northern Mozambique were included in Vallo et al., 2008).

title: Multi-model ensemble predictions of atmospheric turbulence

description: Atmospheric turbulence is a major aviation hazard, costing the aviation industry millions of dollars each year through aircraft damage and injuries to passengers and crew. In this thesis we compare reanalysis data to climate model simulations to understand how well climate models predict the location of Clear-Air Turbulence (CAT). We then model how climate change will impact CAT on a global scale, in all four seasons and at multiple flight levels. This provides ample motivation for the second half of the thesis which aims to improve aviation turbulence forecasting by testing a multi-model ensemble forecast by combing the Met Office Global and Regional Ensemble Prediction System (MOGREPS-G) and the European Centre for Medium Range Weather Forecasting (ECMWF) Ensemble. The main results found are that climate models are able to skilfully predict the location of CAT, with the main uncertainty of the location of CAT coming from which turbulence index is the best and not from the use of a climate model. We also found CAT will increase globally in the future with climate change, for multiple aviation-relevant turbulence strength categories, at multiple flight levels and in all seasons. For ensemble forecasting we started with a single-diagnostic equally weighted multi-model ensemble and found it is at least as skilful as the single-model ensembles. This lack of significant improvement in the forecast skill could be because when increasing the forecast spread, we capture more turbulence events but also more false alarms. The relative economic value of the forecast is improved for the multi-model ensemble, particularly at low cost/loss ratios. Through combining two ensembles we gain consistency, gain more operational resilience and create one authoritative forecast whilst maintaining skill and increasing value. Extending this work further, it is found that these results apply more generally for multiple turbulence diagnostics, as the multi-model ensemble was more skilful than either of the single-model ensembles. When combining the predictors, the multi-diagnostic multi-model ensemble was more skilful than the two single-model ensembles. It was also found that an optimised 12-member ECMWF and MOGREPS-G multi-diagnostic ensemble was more skilful than the 51-member multi-diagnostic ensemble. What this therefore indicates is that a smaller ensemble spread for the individual diagnostics within a multidiagnostic ensemble is important for optimising operational forecasts in the future, which could reduce computational costs for turbulence forecasting.

description: A damped-response formalism in the GW approximation to the Bethe–Salpeter equation (BSE) is presented and implemented. It is based on a quasirelativistic two-component (2c) approach that includes scalar-relativistic and spin–orbit effects derived from the one-electron Dirac equation. A generalised solver, which also allows to calculate static, dynamic and damped-response polarisabilites, is discussed in detail. Throughout our implementation, the resolution-of-the-identity approximation is employed to reduce the computational effort. The performance of 2c GW-BSE is benchmarked against experimental and high-level ab initio data and compared to standard density-functional theory approaches, including modern local hybrid functionals for which a proper non-collinear kernel for Kramers-restricted systems is reported.
No Universality for Electron's Power-Law Index (p) in Gamma-Ray Bursts and Other Relativistic Sources

description: The Gamma-Ray Burst (GRB) prompt emission is believed to be from highly relativistic electrons accelerated in relativistic shocks. From the GRB high-energy power-law spectral indices $β$ observed by the Burst and Transient Source Experiment (BATSE) Large Area Detectors (LAD), we determine the spectral index, $p$, of the electrons' energy distribution. Both the theoretical calculations and numerical simulations of the particle acceleration in relativistic shocks show that $p$ has a universal value $\approx 2.2-2.3$. We show that the observed distribution of $p$ during GRBs is not consistent with a $δ$-function distribution or an universal $p$ value, with the width of the distribution $\ge$ 0.54. The distributions of $p$ during X-ray afterglows are also investigated and found to be inconsistent with a $δ$-function distribution. The $p$-distributions in blazars and pulsar wind nebulae are also broad, inconsistent with a $δ$-function distribution.
