description: Three manure application limits (N Limit, Annual P Limit and P Banking) were modeled with particular attention to the number of hours needed to appropriately distribute manure. The benefit and costs estimates indicated that P Banking was more profitable than N Limit which was more profitable than Annual P Limit. The number of hours required indicated that the Annual P Limit would not be completed within a two month window approximately 2 of 10 years. The increased number of hours for the Annual P Limit also increased the probability of a runoff event following manure application, relative to the other two scenarios. This work indicates that regulations that require Annual P Limits of manure cost the farmer and may have the unintended consequence of increasing runoff.

description: The costs of transporting agricultural products to market and of the acquisition of production inputs are of concern to environmental and food horticulture crops producers. This study is to determine if transportation alliances would reduce shipping costs, increase distribution efficiencies and reduce carbon dioxide emissions among floriculture, ornamental plants, and fruit and vegetable producers in Georgia. Using data from surveys and the ArcLogistics 9.3 GIS software, routing systems were developed to show cost savings opportunities. The results indicated nearly ten percent reductions in average total cost savings to producers, average total miles driven savings, average number of trucks savings, average hours driving savings, and average carbon dioxide (carbon footprint) savings.
Casimir effect in Josephson junctions

description: In a Josephson junction, the supercurrent is determined by both the discrete sub-gap part of the spectrum due to Andreev bound states and the continuous part of the spectrum from energy states outside the superconducting gap. We consider the cohesive force exerted on a junction, which is thermodynamically conjugated to the superflow, and comment on its connection to the Casimir effect in quantum electrodynamics. In contrast to the supercurrent, it is shown that in ballistic short junctions, the force is predominantly contributed by the continuum. Its magnitude is universally defined by the energy gap and coherence length of the superconductor per spin-dependent transverse mode. This force scales non-analytically with the junction length and is periodic with the superconducting phase. For long ballistic junctions, the force results from the interplay of oscillatory contributions originating from both bound states and the continuum. The resulting asymptotic limit for the force is established, including the correction terms. Thermal and impurity effects on the force are briefly discussed.

description: Zusammenfassung : In der vorliegenden Arbeit werden mögliche methodische Ansätze zur Beurteilung von Arbeitsplatzeffekten von Fördermaßnahmen für den ländlichen Raum und insbesondere der Integrierten Ländlichen Entwicklung (ILE) vorgestellt und diskutiert. Aufgenommen wurden auch Methoden, deren Eignung für diese spezifischen Bewertungen verneint wird. Aus diesem Grund ist die vorliegende Arbeit nicht nur mit Blick auf die Bewertung der ILE zu lesen, sondern kann auch über mögliche Herangehensweisen an die Bewertung anderer Maßnahmen zur Entwicklung des ländlichen Raumes informieren. Die Diskussion der verschiedenen Methoden zeigt, dass es notwendig ist, die einer Wirkung zugrunde liegenden Zusammenhänge genau zu kennen, um die tatsächliche Wirkung einer Maß­nahme auf den Arbeitsmarkt zu ermitteln. Es wird gezeigt, dass eine solche ausgereifte theoretische Basis für die ILE noch nicht existiert. Der Anspruch einer belastbaren Quan­tifizierung von Wirksamkeit und Effizienz kann daher zum jetzigen Zeitpunkt noch nicht erfüllt werden. Die Politikbewertung stellt in diesem Fall einen interaktiven Prozess der Wissensgenerierung dar. --------------------------------------------------------------------------------------- Summary: The present work discusses possible methodological approaches for the assessment of employment effects of rural development measures. A special focus is on measures of the so called integrated rural development. Methods that are considered non-appropriate are considered nevertheless. Therefore, this paper may inform more generally about possible approaches towards the assessment of policy effects. The discussion of different methods clarifies the inevitable necessity of intimate causal knowledge of measures’ intervention logics in order to reliably identify employment effects. Since such a sound theoretical basis does not exist yet for the measures of integrated rural development, the demand for a reliable quantification of the measures’ effectiveness and efficiency cannot yet be met. In this case, policy evaluation has to be judged as an interactive process of knowledge generation.

description: Zusammenfassung : Das Ziel der vorliegenden Arbeit besteht in der Bestimmung der Betriebsaufgabewahrscheinlichkeit verschiedener Betriebstypen im Westen Deutschlands in Abhängigkeit von Gewinnniveau und Gewinnentwicklung. Dabei wird davon ausgegangen, dass die Reaktion der Betriebe auch von der erwarteten Nachhaltigkeit der Gewinnschwankungen sowie von der Betroffenheit anderer Betriebe abhängt. Es wird deshalb auch erwartet, dass die Betriebe in Abhängigkeit vom regionalen Kontext unterschiedlich reagieren. Die Gewinnerwartung der Betriebe wird mithilfe des Testbetriebsnetzes des BMELV geschätzt. Die Betriebsaufgabewahrscheinlichkeit wird in einem zweiten Schritt anhand der flächendeckenden Daten der Agrarstrukturerhebung in einem logistischen Modell für verschiedene Betriebstypen bestimmt. Schließlich werden in einem Metamodell die Ursachen für die regionalen Unterschiede der Schätzkoeffizienten untersucht. Die Annahmen bezüglich der differenzierten Wirkungen betrieblicher Gewinnschwankungen auf die Betriebsaufgabeentscheidung werden weitgehend bestätigt. Zentrale Fragen für die zukünftige Forschung mit längeren Zeitreihen werden identifiziert. --------------------------------------------------------------------------------------------------------------------------------------- This working paper aims at the determination of the impact of different profit-levels and changing profits upon farm-exit probabilities of different farm-types in western Germany. It is expected that the farms’ reaction depends on the sustainability of profit-changes as well as on the other farms’ concernment. Therefore we also expect that farms show het-erogeneous reactions depending on the regional context. Farms’ expected profits are es-timated with the help of the German Farm Accountancy Data Network (FADN). Farm-exit probabilities are estimated in a second step within a logistic model based on micro data from the farm structural survey. Finally possible causes for heterogeneous estimators are explored in a meta-model. The assumptions concerning the heterogeneous effects of changing profits are confirmed by the results. Central questions for future analyses with longer time-series are identified.

description: Kagome materials are known for hosting exotic quantum states, including quantum spin liquids, charge density waves, and unconventional superconductivity. The search for kagome monolayers is driven by their ability to exhibit neat and well-defined kagome bands near the Fermi level, which are more easily realized in the absence of interlayer interactions. However, this absence also destabilizes the monolayer forms of many bulk kagome materials, posing significant challenges to their discovery. In this work, we propose a strategy to address this challenge by utilizing oxygen vacancies in transition metal oxides within a "1+3" design framework. Through high-throughput computational screening of 349 candidate materials, we identified 12 thermodynamically stable kagome monolayers with diverse electronic and magnetic properties. These materials were classified into three categories based on their lattice geometry, symmetry, band gaps, and magnetic configurations. Detailed analysis of three representative monolayers revealed kagome band features near their Fermi levels, with orbital contributions varying between oxygen 2p and transition metal d states. This study demonstrates the feasibility of the "1+3" strategy, offering a promising approach to uncovering low-dimensional kagome materials and advancing the exploration of their quantum phenomena.
Five-axis trajectory generation methods
Creators: name: Sencer, Burak
Publisher: name: University of British Columbia
Year: 2009

description: Five-axis machining has been widely adopted manufacturing parts with sculptured surfaces in the aerospace, die and mold and other industries. Five-axis machine tools have a kinematic structure compromising three Cartesian axes couples with two rotary joints enabling the tool to reach any given position and the orientation on the workpiece surface. Five-axis motion allows the orientation of the tool along the toolpaths with varying curvatures and sculptured surfaces. However, optimal trajectory generation methods are required in achieving a smooth coordinated motion of the tool tip and tool axis orientation, which is essential in reducing the fluctuations in the feed, accelerate and jerk of the drives. In this thesis, a toolpath generation algorithm has been developed for smooth trajectories based on compressing the C⁰ continuous Numerical Control (NC) motion commands into continuous b-spline format. With the aid of the b-spline toolpath representation, the discontinuities and unwanted acceleration harmonic in the multi-axis motion are reduces. The tool position and orientation vectors are interpolated continuously enabling a smooth and synchronized motion of the drives. In order to achieve higher smoothness in the change of feed direction, the spline toolpath is optimized by solving the linear quadratic minimization problem during the least squares fit. The resultant angular motion of the tool is further smoothed by minimizing the integral square of third derivative of the orientation spline using a non-linear optimization technique. The Feed Correction Polynomial algorithm is implemented in the real time interpolation of the generated b-spline toolpath yielding a consistent feedrate profile during contouring operations. It is shown that feed correction method exhibits reduced feedrate fluctuations when compared to the widely used Taylor Series approximations. A jerk continuous feedrate profile in terms of C³ quintic spline is adapted for five-axis trajectory generation. The feedrate profile is generated utilizing the minimum jerk criteria for the smoothness of the motion and tracking accuracy. The feed profile is then optimized to achieve minimum cycle time while adhering to the machine tool's velocity, acceleration and jerk limitations. The developed trajectory generation algorithms have been simulated using the kinematics of a widely used five-axis machine tool promising potential applications in rough machining.

Sieve empirical likelihood ratio tests for nonparametric functions

description: Generalized likelihood ratio statistics have been proposed in Fan, Zhang and Zhang [Ann. Statist. 29 (2001) 153-193] as a generally applicable method for testing nonparametric hypotheses about nonparametric functions. The likelihood ratio statistics are constructed based on the assumption that the distributions of stochastic errors are in a certain parametric family. We extend their work to the case where the error distribution is completely unspecified via newly proposed sieve empirical likelihood ratio (SELR) tests. The approach is also applied to test conditional estimating equations on the distributions of stochastic errors. It is shown that the proposed SELR statistics follow asymptotically rescaled χ^2-distributions, with the scale constants and the degrees of freedom being independent of the nuisance parameters. This demonstrates that the Wilks phenomenon observed in Fan, Zhang and Zhang [Ann. Statist. 29 (2001) 153-193] continues to hold under more relaxed models and a larger class of techniques. The asymptotic power of the proposed test is also derived, which achieves the optimal rate for nonparametric hypothesis testing. The proposed approach has two advantages over the generalized likelihood ratio method: it requires one only to specify some conditional estimating equations rather than the entire distribution of the stochastic error, and the procedure adapts automatically to the unknown error distribution including heteroscedasticity. A simulation study is conducted to evaluate our proposed procedure empirically.

Es konnten detaillierte Erkenntnisse über Einstellungen und Ausgestaltung des Engagements gewonnen werden sowie über Art und Umfang der unmittelbaren Erhaltung seltener Nutzpflanzen beziehungsweise Nutztiere: Es werden verschiedenste Arten und Rassen beziehungsweise Sorten erhalten. Vermarktungsaspekte sind wichtig und ’Erhalten durch Essen’ wird einhellig befürwortet. Nur knapp die Hälfte der Befragten schätzt die eigenen Fähigkeiten als ausreichend ein. Unterstützung wird sowohl in Erhaltungsaktivitäten als auch in Vermarktungsfragen gewünscht. Die Ergebnisse bieten Ansatzpunkte, wie der Personenkreis in seinem Bemühen, einen Beitrag zur Erhaltung seltener Nutzpflanzen oder Nutztiere zu leisten, unterstützt werden kann. --------------------------------------------------------------------------------------------------------------------------------------- Summary: The goal of the study „Online Survey of Keepers of rare breeds of domestic animals and cultivated plant varieties about their Activities and Attitudes” is to for the first time characterise this group of persons for Germany and German-language speaking countries. An online survey was carried out with the help of the appropriate associations targeted to these special interest groups. Detailed information on the attitudes and form of involvement could be gained, as well as on the type and extent of the conservation of rare breeds of domestic animals and cultivated plant varieties. Very different species and races, or varieties, are kept. Marketing aspects are important and “use it or lose it” was unanimously recommended. Only a scant half of those surveyed consider their own abilities as adequate for conservation. Support is desired both in terms of maintenance activities and in marketing questions. The results offer a starting point to show where persons contributing to the maintenance of rare plants or animals can be supported.

description: Current science communication has a number of drawbacks and bottlenecks which have been subject of discussion lately: Among others, the rising number of published articles makes it nearly impossible to get an overview of the state of the art in a certain field, or reproducibility is hampered by fixed-length, document-based publications which normally cannot cover all details of a research work. Recently, several initiatives have proposed knowledge graphs (KGs) for organising scientific information as a solution to many of the current issues. The focus of these proposals is, however, usually restricted to very specific use cases. In this paper, we aim to transcend this limited perspective by presenting a comprehensive analysis of requirements for an Open Research Knowledge Graph (ORKG) by (a) collecting daily core tasks of a scientist, (b) establishing their consequential requirements for a KG-based system, (c) identifying overlaps and specificities, and their coverage in current solutions. As a result, we map necessary and desirable requirements for successful KG-based science communication, derive implications and outline possible solutions.

description: This paper presents a review and perspective on quantum gases in bubble traps. We emphasize how the idea of realizing shell shaped condensates emerged and was enabled by the invention of the radiofrequency adiabatic potential technique. We review the many subsequent theoretical works that address the new physics emerging for a condensate trapped on a closed surface. We present the current status of the experiments, the challenges ahead and highlight how a different approach using an immiscible mixture of two condensates enabled the first observation of a shell-shaped degenerate gas. Finally we list a few open questions that we believe provide interesting research directions.

Zahlreiche Statistiken wurden ausgewertet, um prozentuale Aussagen treffen zu können wie viel Rohstoffe in die Biokraftstoffproduktion und weitere energetische Verwendungen floss im Vergleich zu den Bereichen Ernährung und Futter. Außerdem wird aufgezeigt welche Nebenprodukte entstehen und falls möglich deren Mengen quantifiziert. Mittels Handelsstatistiken wurden die importierten Rohstoffmengen ermittelt. Wegen Lücken in der Datenverfügbarkeit wurden die gehandelten Biokraftstoffmengen nur als netto Importe (Verbrauch minus inländische Produktion) aufgezeigt, was zu Abweichungen im Hinblick auf die tatsächlich importierten und exportierten Biokraftstoffmengen führen kann. --------------------------------------------------------------------------------------------------------------------------------------- This working paper analyses the material flows in the German biofuel sector for the year 2007. Several statistics were evaluated to indicate which percentage of raw materials went into biofuel production and further energetic uses versus the sectors food and feed. Further the report mentions which by-products are generated and if possible these are quantified. By the use of trade statistics the quantities of imported raw materials were identified. Trade statistics for biofuels are hard to obtain; therefore only net imports of biofuels (consumption minus national production) were calculated which can lead to discrepancies regarding the actual imported and exported biofuel quantities.

description: We analyze the propagation of experimentally relevant two-particle correlations for one-dimensional interacting bosons, and give evidence that many-body chaos induces the emergence of an effective diffusive regime for the fully coherent correlation dynamics, characterized by an interaction dependent diffusion coefficient, which we estimate. This result supports very recent experimental observations, and paves the way towards an efficient description of the dynamical behaviour of non-integrable complex many-body systems. Furthermore, we show that the dynamical features within experimentally accessible time scales of a conveniently defined two-particle correlation transport distance provide a direct and unambiguous characterization of many-body quantum chaos in perfect agreement with its spectral identification.

description: Financial development has been argued as a potential source of comparative advantage and its relationships with trade has been theoretically developed. This theory posits that countries that are well financially developed should experience greater volumes of international trade. We empirically investigate the effects of financial development on trade of both agricultural and manufactured products. The results show a positive impact of financial development on bilateral trade flows for the manufacturing sector, which enjoys a greater impact than the agricultural sector. The impacts differ across regions. In most cases, developing countries (Asia, Latin America, MENA and SSA) experience greater impacts of financial development on exports in both agriculture and manufacturing sectors than do advanced countries.

description: The COVID-19 pandemic has affected people's lives in many ways. Social media data can reveal public perceptions and experience with respect to the pandemic, and also reveal factors that hamper or support efforts to curb global spread of the disease. In this paper, we analyzed COVID-19-related comments collected from six social media platforms using Natural Language Processing (NLP) techniques. We identified relevant opinionated keyphrases and their respective sentiment polarity (negative or positive) from over 1 million randomly selected comments, and then categorized them into broader themes using thematic analysis. Our results uncover 34 negative themes out of which 17 are economic, socio-political, educational, and political issues. 20 positive themes were also identified. We discuss the negative issues and suggest interventions to tackle them based on the positive themes and research evidence.

description: The Arkansas Global Rice Model is based on a multi-country statistical simulation and econometric framework. The model is disaggregated by five world regions: Africa, the Americas, Asia, Europe, and Oceania. Each region includes country models which have a supply sector, a demand sector, a trade, stocks and price linkage equations. All equations used in this model are estimated using econometric procedures or identities. Estimates are based upon a set of explanatory variables including exogenous macroeconomic factors such as income, population, inflation rate, technology development, and especially, government determined policy variables which reflect the various mechanisms by which countries intervene in their rice sector economy. Individual country models are linked through net trade to recognize the interdependence of countries in the world rice economy.

description: We reanalyze published magnetization data and demonstrate that the conclusion of the original authors, claiming enhanced two-dimensional properties of the cuprate superconductor Tl-1234, is not supported by the experimental results. Our analysis shows that the magnetic field dependence of the mixed-state magnetization for this particular sample is amazingly close to the results of numerical calculations by E. H. Brandt for an ideal vortex lattice without fluctuations. This good agreement between experiment and theory allows for the evaluation of the absolute values of the upper critical field.

By understanding the patterns and routines in artists’ behaviours as unique features of creative knowledge making, The Habits of Artists seeks to deepen our insight into art learning. Employing a unique platform through which the audience is engaged in public learning as performance, the research asks whether we can find fitting frameworks for communicating the complexities of art practice, in which often subjective and bespoke logics drive creativity.

description: In this note we consider a quantum mechanical particle moving inside an infinitesimally thin layer constrained by a parabolic well in the $x$-direction and, moreover, in the presence of an impurity modelled by an attractive Gaussian potential. We investigate the Birman-Schwinger operator associated to a model assuming the presence of a Gaussian impurity inside the layer and prove that such an integral operator is Hilbert-Schmidt, which allows the use of the modified Fredholm determinant in order to compute the bound states created by the impurity. Furthermore, we consider the case where the Gaussian potential degenerates to a $δ$-potential in the $x$-direction and a Gaussian potential in the $y$-direction. We construct the corresponding self-adjoint Hamiltonian and prove that it is the limit in the norm resolvent sense of a sequence of corresponding Hamiltonians with suitably scaled Gaussian potentials. Satisfactory bounds on the ground state energies of all Hamiltonians involved are exhibited.

We present a combined experimental and computational investigation of the mechanical properties of a CoCrFe0.75NiMo0.3Nb0.125 (composition in molar ratio) high-entropy alloy additively manufactured via cold spray. We find that the sprayed alloy exhibits extraordinary mechanical properties under compression, reaching yield stress of ~1745 MPa, ultimate stress of ~2622 MPa, and a maximum strain at failure of ~9%. These exceptional mechanical properties are the result of four independent hardening mechanisms. First, using ab initio simulations, we find that non-equiatomic compositions increase the enthalpy of mixing, promoting better solubility of solute Mo and Nb atoms while simultaneously preserving the electronegativity of the base alloy. The higher solubility results in solid-solution hardening and nanosized precipitate formation, promoting additional hardening. These effects are confirmed in the experimental characterization of the manufactured HEA, where nanosized precipitates of ~226 ± 65 nm in size are identified. Additional hardening effects are associated with the manufacturing process, where the high-velocity impacts of the microparticles promote dynamic recrystallization through dislocation emission and grain refinement. To understand the dynamic recrystallization of particles, high-velocity impact simulations using molecular dynamics are performed. We find that when particles reach a critical impact velocity ( ~600–800 m ⋅ s−1), the dislocation density reaches a maximum, and grain refinement is maximized. The decaying wave pressures developed during the impact generate gradual refinement levels, leading to heterogeneous microstructures combining nano and micro grains, which was later confirmed experimentally using electron backscatter diffraction. These subtle atomic and microstructural features result in outstanding experimentally evaluated yield and ultimate stresses compared to other high-entropy alloys with similar compositions.
All fundamental fermions fit inside one su(1|5) irreducible representation

description: We present the mathematical framework for a unified theory based upon su(1|5). The Lie superalgebra su(1|5) has irreducible representations of dimension 32, in which the 32 fundamental fermions of one generation (leptons and quarks, of left and right chirality, and their antiparticles) can be accommodated. The branching of these su(1|5) representations with respect to its subalgebra su(3) x su(2) x u(1) reproduces precisely the classification of these fundamental fermions according to the gauge group of the Standard Model. Furthermore, a simple construction of the relevant representations is given, and some consequences are discussed.

description: A supply management system governs Canada’s poultry sector. Tariff Rate Quotas (TRQs), with prohibitive above-quota tariffs and low in-quota tariff, mimic import-quotas limit international competition in Canada’s poultry market. The quota part of the TRQs is a minimum access commitment under international trade agreement that is defined as a fraction of domestic production. We show in a 3-stage game involving negotiations between retailers and processors and between processors and farms that increasing minimum access commitment under current trade agreements can produce Metzler effects with larger price increases observed at the farm and processing levels. Simulations based on 2008 data support the Metzler paradox and shed light on import license allocations between retailers and poultry processors in Canada.
Spatial clustering of depinning avalanches in presence of long-range interactions

description: Disordered elastic interfaces display avalanche dynamics at the depinning transition. For short-range interactions, avalanches correspond to compact reorganizations of the interface well described by the depinning theory. For long-range elasticity, an avalanche is a collection of spatially disconnected clusters. In this paper we determine the scaling properties of the clusters and relate them to the roughness exponent of the interface. The key observation of our analysis is the identification of a Bienaym{é}-Galton-Watson process describing the statistics of the cluster number. Our work has a concrete importance for experimental applications where the cluster statistics is a key probe of avalanche dynamics.
