description: The use of impending crop yield futures contracts to hedge expected net revenue is examined. The expectation being modeled here reflects that of an Illinois corn and soybean producer in March of the revenue realized after harvest. The effects of using price and yield contracts are measured by comparing the resulting expected distribution to the expected distribution found under five general alternatives: (1) a revenue hedge using just price futures, (2) a revenue hedge using just yield futures, (3) a no-hedge scenario where revenue is determined by realized price and yield, (4) a no-hedge scenario where revenue is determined by the market and by participating in the current deficiency payment program, and (5) a no-hedge scenario where revenue is determined by the market and by participating in a proposed revenue-assurance program. Three major conclusions are drawn. First, hedging effectiveness using the new crop yield contract depends critically on yield basis risk which presumably can be reduced considerably by covering large geographical areas. Second, crop yield futures can be used in conjunction with price futures to derive risk management benefits significantly higher than using either of the two alone. Third, hedging with price and crop yield futures can potentially offer benefits that are large relative to the revenue assurance program analyzed. However, the robustness of the findings depends largely on whether yield basis risk varies significantly across regions.

description: We investigated students' use of Newton's second law in mechanics and electromagnetism contexts by interviewing students in a two-semester calculus-based physics course. We observed that students' responses are consistent with three mental models. These models appeard in mechanics contexts and were transferred to electromagnetism contexts. We developed an inventory to help instructors identify these models and direct students towards the correct one.

description: This paper continues Deaton and Laroque's search for a variant of the nonlinear rational expectations commodity storage model that can explain the observed behavior of primary commodity prices. Using numerical functional equation methods and Monte Carlo simulation techniques, we demonstrate that the failure of Deaton and Laroque's model to explain high autocorrelation in primary commodity prices is attributable to the assumption of a constant returns to storage technology. Our findings suggest that a classical cost of storage function with "convenience yield" can give a satisfactory explanation for the high autocorrelation.

description: The basal macronarian sauropod Europasaurus holgeri is known only from the Late Jurassic of the Langenberg Quarry near Goslar, Lower Saxony, Germany. Europasaurus has been identified as an insular dwarf and shows a clear resemblance to Camarasaurus and Giraffatitan. This study provides a detailed description of the dentition of Europasaurus based on an array of fossils outstanding in their abundance, variety of preservation, and ontogenetic range. Dental morphology for the replacement and functional dentitions, the tooth replacement pattern, and implications for food intake are described for the Europasaurus dentition, which is characterized by broad-crowned teeth. Characteristic features for Europasaurus are the presence of denticles on replacement teeth, the wrinkled enamel, and large wear facets both on the apex and on the carinae of the tooth crowns. The partially articulated skull SNHM-2207-R and isolated tooth rows DfmMh/FV 580.1 and DfmMh/FV 896.7 suggest the presence of strong connective tissue partially covering the teeth. This connective tissue would have provided stability and protection for the teeth. Evidence for this connective tissue include exposed tooth necks, in-situ teeth with strongly resorbed roots which no longer would have been connected to the jaw bone, and wrinkled enamel and its surface pattern. The same features can be observed in other sauropod taxa as well. We therefore suggest that eusauropods in general possessed this connective tissue structure, which may be an autapomorphy of the group. Possibly, this hypothetical structure is homologous to the rhamphotheca in birds and some non-avian theropods, which, however rarely, show such a close integration of keratinous tissue and teeth that we hypothesize here.

description: Background: General practitioners (GPs) play a crucial role in identifying cognitive impairment and dementia and providing post-diagnostic care. This study investigates (1) how promising GP consider lifestyle changes to maintain cognitive performance in general, (2) GP beliefs about the power of modifiable health and lifestyle factors to maintain cognitive performance, and (3) whether those beliefs vary by GP age. Methods: As part of the AgeWell.de trial, GPs (n = 72) completed a process evaluation questionnaire assessing their perspectives on lifestyle changes to preserve cognitive performance in elderly patients. In greater detail, their perceived efficacy of established risk and protective factors was investigated using a 5-point Likert scale. Descriptive statistical analyses were performed for research question (1) and (2). Spearman´s rank correlations and ordinal logistic regressions were used to answer research question (3). All results were interpreted exploratively. Results: GPs rated the overall chance of lifestyle changes maintaining cognitive performance quite neutral with a median score of 3.0 (IQR = 2.0). They rated the efficacy of all the modifiable health and lifestyle factors high, with increase in physical and social activity ((Mdn = 5.0, IQR = 1.0) receiving the highest ratings with the narrowest range. Spearman's rank correlation indicated a significant positive relationship between age and the belief in “Optimization of nutrition” for preventing cognitive decline and dementia (ρ = .255, p = .041). However, ordinal logistic regressions showed no significant relationships between age and GP ratings of lifestyle change efficacy. Conclusion: These findings highlight the positive perception of GPs on the efficacy of modifiable health and lifestyle factors for preventing cognitive decline and dementia.

description: Liposomal formulations of antibiotics for inhalation offer the potential for the delivery of high drug doses, controlled drug release kinetics in the lung, and an excellent safety profile. In this study, we evaluated the in vivo performance of a liposomal formulation for the poorly soluble, antituberculosis agent, bedaquiline. Bedaquiline was encapsulated within monodisperse liposomes of ∼70 nm at a relatively high drug concentration (∼3.6 mg/mL). Formulations with or without fucose residues, which bind to C-type lectin receptors and mediate a preferential binding to macrophage mannose receptor, were prepared, and efficacy was assessed in an in vivo C3HeB/FeJ mouse model of tuberculosis infection (H37Rv strain). Seven intranasal instillations of 5 mg/kg bedaquiline formulations administered every second day resulted in a significant reduction in lung burden (∼0.4–0.6 Δlog10 CFU), although no differences between fucosylated and nonfucosylated formulations were observed. A pharmacokinetic study in healthy, noninfected Balb/c mice demonstrated that intranasal administration of a single dose of 2.5 mg/kg bedaquiline liposomal formulation (fucosylated) improved the lung bioavailability 6-fold compared to intravenous administration of the same formulation at the same dose. Importantly, intranasal administration reduced systemic concentrations of the primary metabolite, N-desmethyl-bedaquiline (M2), compared with both intravenous and oral administration. This is a clinically relevant finding as the M2 metabolite is associated with a higher risk of QT-prolongation in predisposed patients. The results clearly demonstrate that a bedaquiline liposomal inhalation suspension may show enhanced antitubercular activity in the lung while reducing systemic side effects, thus meriting further nonclinical investigation.

description: This paper examines the accuracy of preharvest corn yield forecasts from crop-weather models for major U.S Corn Belt states. Cross section time series models using dummy variables to represent state crop reporting districts are estimated via ordinary least squares for Iowa, Illinois and Indiana. The models use normalized rainfall and temperature data and measures of crop maturity for the1972-1991 period. Four successive corn crop- weather models are estimated for each state using information available on July 1, August 1, September 1 and October 1, respectively. Crop reporting district level yield forecasts and forecast errors are derived via unconditional forecast error calculatlions. These forecasts and forecast errors are then aggregated together on a monthly basis throughout the growing season to form state yield forecasts and confidence intervals. During the 1992-1994 period, forcast accuracy was poor when weather conditions were abnormal compared to the average conditions during the period of model estimation. This is illustrated by inaccurate forecasts for 1992 and 1993 for Iowa caused by abnormally wet and cool conditions. Future crop yield forecasting efforts should focus on the use of resource capture models, which hold promise of producing more accurate forecasts than crop-weather models.

description: Each of electrically charged particles testifies in favor of the existence of a kind of the magnetically charged monoparticle. As a consequence, only the corresponding mononeutrinos answer for quantization of the electric charges of all neutrinos. Therefore, to understand the nature of matter at the fundamental level, one must use the electromagnetic field as the field of the unified system of the photon and monophoton where the electric and magnetic forces of the nature are united. Some logical and laboratory confirmations of the availability of compound structure of gauge invariance have been listed which say also about the connection between the states of elementary particles and monoparticles.

description: We analyze the halo occupation distribution (HOD), the probability for a halo of mass M to host a number of subhalos N, and two-point correlation function of galaxy-size dark matter halos using high-resolution dissipationless simulations of the concordance flat LCDM model. The halo samples include both the host halos and the subhalos, distinct gravitationally-bound halos within the virialized regions of larger host systems. We find that the first moment of the HOD, (M), has a complicated shape consisting of a step, a shoulder, and a power law high-mass tail. The HOD can be described by a Poisson statistics at high halo masses but becomes sub-Poisson for <4. We show that the HOD can be understood as a combination of the probability for a halo of mass M to host a central galaxy and the probability to host a given number Ns of satellite galaxies. The former can be approximated by a step-like function, while the latter can be well approximated by a Poisson distribution, fully specified by its first moment (M). We find that ~M^b with b~1 for a wide range of number densities, redshifts, and different power spectrum normalizations. This formulation provides a simple but accurate model for the halo occupation distribution found in simulations. At z=0, the two-point correlation function (CF) of galactic halos can be well fit by a power law down to ~100/h kpc with an amplitude and slope similar to those of observed galaxies. At redshifts z>~1, we find significant departures from the power-law shape of the CF at small scales. If the deviations are as strong as indicated by our results, the assumption of the single power law often used in observational analyses of high-redshift clustering is likely to bias the estimates of the correlation length and slope of the correlation function.

description: Additional file 4: Model 11 with 95% Prediction Intervals. For a given MT, CLADE and T2T, CR is expected to fall within these intervals in 95% of cases. T2T shifts this prediction interval up or down depending on its value. In order to present the prediction intervals for Model 11 in a 2D graphic, we plotted two ribbons which represent the minimum (1.8%; dark grey) and maximum (16.7%; light grey) T2T values observed in this study. This shows the extent that the prediction interval could be expected to shift if two individuals within the same CLADE had the same MT, but extremely different T2T. CR which were predicted to be negative values (e.g., − 100 clicks/second) were set to 0 clicks/sec because negative rates would not be biologically meaningful.

description: Objective: To identify the most relevant aspects of global scientific research on biochar in terms of number of articles published, main authors and publishing countries, citation, main issues of scientific journals, funding institutions and general trends. Design/Methodology/Approach: A bibliometric study was carried out in the Scopus database. The word “biochar” was used in the search engine. The search was limited to articles and reviews published from 2009 to March 2020. The VOS viewer software was used to identify the main thematic axes and to glimpse the knowledge gaps that exist to date. Results: A total of 11,444 documents were identified. The trend of work on biochar is on the rise. China and the United States are the countries with the highest number of publications on biochar. Jefferson Lehman and Stephen Josephs are the most cited authors on the subject. Global research on biochar focuses on the mitigating effect of climate change and good properties that biochar has to improve physicochemical properties of the soil. Research on biochar in Mexico is scarce. Study Limitations/Implications: Biochar is a new technology that is not fully understood. Findings/Conclusions: Interest in biochar as a multifaceted solution to agricultural and environmental problems is growing at a rapid rate both domestically and internationally

Diagnosis. Placed in the subgenus Pareumenes due to the lateral carina of propodeum forming a sharp triangular lobe, the propodeal valvula forming a long lobe strongly exceeding the apex of the propodeum, and the elongate and petiolate T1 with a basal angle, it is recognized from the other species of the subgenus by the mostly impunctate and velvety body, the wider and shallower apical emargination of clypeus, the largely smooth posterior depression of propodeum, the long, robust and flattened lobes of the lateral carina of propodeum, the more elongate T1 (2.3–2.6× as long as apically wide) with a deep pit near the posterior end, the decolorate and lamellar apical margin of T1, the barely reflexed apical margin of T2 not forming a distinct lamella, and the strongly silvery pubescence.

Notes. Giordani Soika (1944, 1979, 1981) used a broad concept of Pareumenes sansibaricus and divided this species into six subspecies differentiated only by pattern. Examination of type specimens and additional material revealed in fact the presence of morphological differences that allow to recognize all the subspecies as distinct species. The differences are resumed under each taxon and in the identification key.

description: Three technical analysis tools-relative strength index (RSI), dual moving average and directional movement indicator-are applied to 1987-92 live hog futures market behavior to determine whether profitable trading rules could be devised which would continue to be proftable out-ofsample. A wide range of critical signaling points for each method is evaluated in conjunction with nine stop loss levels. The relative strength index is the only technique found to perform proftably and consistently. Out-of-sample performance of the best 1987-88 RSI trading rules is proftable, and the general performance of RSI trading rules is positively correlated over two year blocks during 1987-92. Dual moving average and directional movement indicator trading rules did not perform well in live hog futures.

description: We report the observation of radar echoes from the ionization trails of high-energy particle cascades. These data were taken at the SLAC National Accelerator Laboratory, where the full electron beam ($\sim$10$^9$ e$^-$ at $\sim$10 GeV/e$^-$) was directed into a plastic target to simulate an ultra high-energy neutrino interaction. This target was interrogated with radio waves, and coherent radio reflections from the cascades were detected, with properties consistent with theoretical expectations. This is the first definitive observation of radar echoes from high-energy particle cascades, which may lead to a viable neutrino detection technology for energies $\gtrsim 10^{16}$ eV.

description: The idea has been spoken that any of Dirac and Pauli form factors of leptonic current includes both normal and anomalous components. From this point of view, the dependence of independent parts of charge and magnetic moment is established with the use of cross sections of elastic scattering of unpolarized and longitudinal polarized electrons and their neutrinos by spinless nuclei. Some considerations of a connection between the mass of a particle and its electromagnetic nature are listed which can explain also the appearance of gravitational field of a Coulomb interaction. All they state that a massive four-component neutrino similarly to the electron must have the normal as well as the anomalous electric charge.

description: Adverse publicity about food contamination can depress demand, causing lost producer revenue. TV and print news coverage of bacterial contamination of chicken in the U.S. is incorporated into an inverse demand for chicken which is estimated using 1982 and 1991 data. A beta binomial audience-exposure distribution is used to estimate net reach and average frequency of exposure to contamination publicity. It was found that for each unit of increase in weekly publicity frequency, prices were depressed by 1.2 percent, leading to a $760 million retail loss to the chicken industry. This amounts to less than one-quarter of one percent of revenue over the ten years studied.

Special emphasis is placed here on the realized development costs aspect, since the calculation at the sales analysis is based on them. The market analysis consists of a detailed analysis of the German market as a coarser of the European and world market. Then a sales analysis will be performed which bases on the data from the product analysis and the researched markets. Hereby the objective is to get first performances of a possible turnover on the German, European and global market.

Subjects: subject: 004 Informatik

description: This document describes the work done during the Research Semester in Summer 2006 of Prof. Dr. Stefan Wohlfeil. It is about Security Management tasks and how these tasks might be supported by Open Source software tools. I begin with a short discussion of general management tasks and describe some additional, security related management tasks. These security related tasks should then be added to a software tool which already provides the general tasks. Nagios is such a tool. It is extended to also perform some of the security related management tasks, too. I describe the new checking scripts and how Nagios needs to be configured to use these scripts. The work has been done in cooperation with colleagues from the Polytech- nic of Namibia in Windhoek, Namibia. This opportunity was used to also establish a partnership between the Department of Computer Science at FH Hannover and the Department of Information Technology at the Polytechnic. A first Memorandum of Agreement lays the groundwork for future staff or student exchange.

description: Current IRS policy on deductibility of losses on futures trades discourages cattle feeders from being fully involved in the price discovery process. Analysis suggests the policy hurts the effectiveness of price discovery and imposes a cost on society at large. Cattle feeders are forced to make all adjustments in the cash side of their business by changing placements, and when negative margins are being offered, they must function as cash market speculators or allow unused capacity and absorb the costs of investment. There is no economically rational way cattle feeders can participate in the price discovery process under current IRS policy when the margins being offered are negative. A change in policy is proposed that would allow feeders to be long in cash cattle and/or distant live cattle futures up to feedlot capacity with losses in futures trades being treated as a deduction for tax purposes. The change should improve the price discovery process, produce a significant consumer surplus, increase market share for the beef sector, and it could increase revenues to the IRS. Conceptual and empirical support for a change in policy is presented. Research results that show the impact of different trader groups, including cattle feeders, on the effectiveness of price discovery are presented in support of the proposed change. More research on the impact of IRS revenues, where the results of a policy change are less definitive, and the related implications of the elasticity of demand for slaughter cattle is needed.

description: As in the car industry for quite some time, dynamic simulation of complete vehicles is being practiced more and more in the development of off-road machinery. However, specific questions arise due not only to company structure and size, but especially to the type of product. Tightly coupled, non-linear subsystems of different domains make prediction and optimisation of the complete system's dynamic behaviour a challenge. Furthermore, the demand for versatile machines leads to sometimes contradictory target requirements and can turn the design process into a hunt for the least painful compromise. This can be avoided by profound system knowledge, assisted by simulation-driven product development. This paper gives an overview of joint research into this issue by Volvo Wheel Loaders and Linkoping University on that matter, lists the results of a related literature review and introduces the term "operateability". Rather than giving detailed answers, the problem space for ongoing and future research is examined and possible solutions are sketched.

description: The RAVER1 protein serves as a co-factor in guiding the polypyrimidine tract-binding protein (PTBP)-dependent control of alternative splicing (AS). Whether RAVER1 solely acts in concert with PTBPs and how it affects cancer cell fate remained elusive. Here, we provide the first comprehensive investigation of RAVER1-controlled AS in cancer cell models. This reveals a pro-oncogenic role of RAVER1 in modulating tumor growth and epithelial-mesenchymal-transition (EMT). Splicing analyses and protein-association studies indicate that RAVER1 guides AS in association with other splicing regulators, including PTBPs and SRSFs. In cancer cells, one major function of RAVER1 is the stimulation of proliferation and restriction of apoptosis. This involves the modulation of AS events within the miR/RISC pathway. Disturbance of RAVER1 impairs miR/RISC activity resulting in severely deregulated gene expression, which promotes lethal TGFB-driven EMT. Among others, RAVER1-modulated splicing events affect the insertion of protein interaction modules in factors guiding miR/RISC-dependent gene silencing. Most prominently, in all three human TNRC6 proteins, RAVER1 controls AS of GW-enriched motifs, which are essential for AGO2-binding and the formation of active miR/RISC complexes. We propose, that RAVER1 is a key modulator of AS events in the miR/RISC pathway ensuring proper abundance and composition of miR/RISC effectors. This ensures balanced expression of TGFB signaling effectors and limits TGFB induced lethal EMT.

description: Der Begriff der Wirtschaft wird in idealistischer Denktradition als Entscheidungskalkül im Hinblick auf Knappheiten definiert. Aber menschliche Gesellschaften reproduzieren sich durch Arbeit, die auf das Ziel der Bedürfnisbefriedigung bezogen ist. Die Wirksamkeit dieser Arbeit steigt im Verlauf der geschichtlichen Entwicklung durch Arbeitsteilung und Arbeitskooperation an, wobei Erfahrungen, Erkenntnisse und die Anwendung von Wissen als Hebel wirken. Bisher wurden die Entwicklungsstufen Naturalwirtschaft, Geldwirtschaft und Kapitalwirtschaft durchlaufen, und als Perspektive zeichnet sich die Sozialwirtschaft ab. Wirtschaft ist kein Selbstzweck; ihre Aufgabe ist es lediglich, dauerhaft die notwendigen Mittel zum gesellschaftlichen Leben bereit zustellen. Die Überwindung der Armut ist die Voraussetzung für ein Leben in menschlicher Würde und für die freie persönliche Entfaltung der gesellschaftlichen Individuen. Die Bestimmung der der Wirtschaft übergeordneten gesellschaftlichen Zwecke ist ausschließlich eine demokratisch-politische Aufgabe der Gesellschaft.

description: Recent experimental results on the static or quasistatic response of granular materials have been interpreted to suggest the inapplicability of the traditional engineering approaches, which are based on elasto-plastic models (which are elliptic in nature). Propagating (hyperbolic) or diffusive (parabolic) models have been proposed to replace the `old' models. Since several recent experiments were performed on small systems, one should not really be surprised that (continuum) elasticity, a macroscopic theory, is not directly applicable, and should be replaced by a grain-scale (``microscopic'') description. Such a description concerns the interparticle forces, while a macroscopic description is given in terms of the stress field. These descriptions are related, but not equivalent, and the distinction is important in interpreting the experimental results. There are indications that at least some large scale properties of granular assemblies can be described by elasticity, although not necessarily its isotropic version. The purely repulsive interparticle forces (in non-cohesive materials) may lead to modifications of the contact network upon the application of external forces, which may strongly affect the anisotropy of the system. This effect is expected to be small (in non-isostatic systems) for small applied forces and for pre-stressed systems (in particular for disordered systems). Otherwise, it may be accounted for using a nonlinear, incrementally elastic model, with stress-history dependent elastic moduli. Although many features of the experiments may be reproduced using models of frictionless particles, results demonstrating the importance of accounting for friction are presented.

description: This paper reports observations of a 22 GHz water maser `superburst' in the G25.65+1.05 massive star forming region, conducted in response to an alert from the Maser Monitoring Organisation (M2O). Very long baseline interferometry (VLBI) observations using the European VLBI Network (EVN) recorded a maser flux density of $1.2 \times 10^{4}$ Jy. The superburst was investigated in the spectral, structural and temporal domains and its cause was determined to be an increase in maser path length generated by the superposition of multiple maser emitting regions aligning in the line of sight to the observer. This conclusion was based on the location of the bursting maser in the context of the star forming region, its complex structure, and its rapid onset and decay.

description: We compute the Grothendieck group K_0 of non-commutative analogues of quantum projective space bundles. Our results specialize to give the Grothendieck groups of non-commutative analogues of projective spaces, and specialize to recover the Grothendieck group of a usual projective space bundle over a regular noetherian separated scheme. As an application we develop an intersection theory for the quantum ruled surfaces defined by Van den Bergh.
