description: We unravel the critical role of vibrational mode softening in single-molecule electronic devices at high bias. Our theoretical analysis is carried out with a minimal model for molecular junctions, with mode softening arising due to quadratic electron-vibration couplings, and by developing a mean-field approach. We discover that the negative sign of the quadratic electron-vibration coupling coefficient can realize at high voltage a sharp negative differential resistance (NDR) effect with a large peak-to-valley ratio. Calculated current-voltage characteristics, obtained based on ab initio parameters for a nitro-substituted oligo(phenylene ethynylene) junction, agree very well with measurements. Our results establish that vibrational mode softening is a crucial effect at high voltage, underlying NDR, a substantial diode effect, and the breakdown of current-carrying molecular junctions.

description: We present new HST STIS NUV-MAMA and STIS CCD observations of the BL Lac object AO 0235+164 and the intervening damped Ly alpha (DLA) line at z_a = 0.524. The line profile gives N(H I) = 5 +/- 1 x 10^{21} cm^{-2} and, combined with the H I 21 cm absorption data leads to a spin temperature of T_s = 220 K +/- 60 K. Those spectra also show a strong, broad feature at the expected position of the 2175 Angstrom graphitic dust feature at z_a = 0.524. Assuming a Galactic type dust extinction curve at z_a = 0.524 gives a dust-to-gas ratio of 0.19 Galactic, but the fit, assuming the underlying, un-reddened spectrum is a single power-law, is poor in the far-UV. A dust-to-gas ratio of 0.19 Galactic is similar to the LMC, but the AO 0235+164 spectrum does not fit the LMC extinction curve, or the SMC extinction curve (which has practically no 2175 Angstrom feature). A possible interpretation includes dust similar to Galactic, but with less of the small particles that produce the far-UV extinction. The metallicity of the z_a = 0.524 absorber, estimated from the observed N(H I) and excess X-ray absorption (beyond Galactic) derived from contemporaneous and archival ASCA and ROSAT X-ray data, is Z = 0.72 +/- 0.28 Z_sun, implying in turn the dust-to-metals ratio of 0.27 Galactic. If the dust mass density is the same in the z_a = 0.524 DLA system as in our Galaxy, only 14% (+/- 6%) of the metals (by mass) are in dust compared with 51%, 36%, and 46% for the Galaxy, LMC, and SMC respectively. Such a dusty z_a = 0.524 AO 0235+164 absorption system is a good example of the kind of DLA system that will be missed due to selection effects, which in turn can bias the measurement of the co-moving density of interstellar gas (in units of the closure density), Omega_g, as a function of z.

Dimitrije Mitrinovic : chameleon, good European, and exiled Yugoslavist
Creators: name: Page, David Graham
Publisher: name: University of British Columbia
Year: 2009

description: This present work is an assessment of the life and thought of Dimitrije Mitrinovic (1887-1953) during his formative years, from his childhood through to 1920, when he resigned from the service of the newly created Kingdom of Serbs, Croats, and Slovenes. His Yugoslavism has yet to be adequately contextualized, at least in the literature accessible to English language readers; Chapter 1 of the present work begins to fill this gap. Mitrinovic's struggle against the Hapsburg domination of the South Slavs is the subject of Chapter 2, in which the influence on Mitrinovic of T. G. Masaryk's thought is detailed. The focus in Chapter 3 is on Mitrinovic's attempt to organize a movement for European unity whilst the continent staggered on the brink of the First World War. The theoretical literature on balkanism is taken as the point of departure in Chapter 4, in which Mitrinovic's ambivalent attitude to balkanist discourse is subjected to scrutiny.
A Search for Anomalous Heavy-Flavor Quark Production in Association with W Bosons

description: We present a search for anomalous production of heavy-flavor quark jets in association with a W boson at the Fermilab Tevatron ppbar Collider. This search is conducted through an examination of the exclusive jet spectrum of W+jets final states in which the heavy-flavor quark content has been enhanced by requiring at least one tagged jet in an event. Jets are tagged by the combined use of two algorithms, one based on semileptonic decays of b/c hadrons, and the other on their lifetimes. We compare data in e+jets (164 pb-1) and mu+jets (145 pb-1) channels, collected with the D0 detector at sqrt{s}=1.96 TeV, to expectations from the standard model, and set upper limits on anomalous production of such events.

description: Livestock is recognized as one of the major drivers of current and future global change. This is caused on the production side, by the substantial resource requirements (land and water) per unit of output, and the related greenhouse gas emissions, and on the consumption side, by the growing demand due to population and economic growth. Our paper investigates whether productivity gains which enabled to the crop sector to satisfy the increased demand under decreasing real prices, and with little additional land, in the past decades, can be expected in the livestock sector in the future. To answer this question, we implement the recursively dynamic partial equilibrium bottom-up model of the global agriculture and forest sectors (GLOBIOM), expanded by a newly developed livestock module. The livestock module is based on the Sere and Steinfeld livestock production system classification, characterized by detailed input-output coefficients, including manure and greenhouse gas emissions. Our results show that if the production system composition is allowed to freely adapt to economic and resource constraints, the increases in per hectare productivity will allow satisfying the 2030 demand for ruminant products with less land than in 2000, and the livestock product prices will remain stable. This contrasts with the numbers obtained, when the ruminant production system structure is kept constant as in 2000, resulting among others in three times higher carbon prices. The adaptation in the livestock sector is hence a condition for sustainable future development, and it has to be taken into account when designing future policies.

description: Das Sachsenkonsortium ist mit 16 wissenschaftlichen Bibliotheken ein vergleichsweise kleines Konsortium bei maximaler Diversität bezüglich der Einrichtungsgrößen und der Studienschwerpunkte – von Volluniversitäten, über Fachhochschulen mit technischem und wirtschaftlichen Schwerpunkt bis hin zu auf Kunst, Musik und Tanz spezialisierten Hochschulen. Der Vortrag möchte zeigen, wie es trotz dieser Vielfalt gelingen kann, verschiedenste Aspekte der OA-Transformation gezielt zu steuern und zu gestalten. Zur Stärkung der OA-Publikation von Monographien wurden z. B erstmalig ab 2019 zentrale OA-Komponenten in klassische Evidence-Based-Selection-Modelle mit Verlagen wie De Gruyter oder Taylor & Francis verhandelt sowie 2020 ein zentraler sächsischer Publikationsfonds für die Finanzierung von Book Processing Charges sächsischer Autor:innen etabliert. Über eigens verhandelte Rahmenverträge mit kleineren und mittleren Verlagen wie z. B. Copernicus und die Beteiligung an konsortialen Finanzierungsmodellen wie etwa Open Library Politik und Medienwissenschaften oder Open Book Publishers versucht das Sachsenkonsortium der anhaltenden Oligopolbildung entgegenzuwirken und stattdessen einen pluralen Publikationsmarkt zu fördern. Über finanzielle Unterstützung von z. B. KOALA, OLEcon, Steinbeis Verfassungsblog, Scipost setzt sich das Sachsenkonsortium verstärkt für wissenschaftsgeleitete und medienbezogene Publikationsorte ein. Mittels systematischer finanzieller und auch konzeptioneller Beteiligung an OA-Infrastrukturen wie Directory of Open Access Journals, Directory of Open Access Books, Open Access Publishing in European Networks, Data Cite, ROR, Open Alex, Open Citations und Public Knowledge Project sollen zum einen die Geschäftsgänge im OA professionalisiert und nachhaltig gestärkt werden, zum anderen wird eine zunehmende Unabhängigkeit von großen kommerziellen, kostenintensiven Playern (Scopus, Clarivate, etc.) angestrebt. Investitionen in die Weiterentwicklung von an sächsischen Hochschulen eingesetzter Open-Access-Infrastruktur (FOLIO, PANTER) sichern die Berücksichtigung der Anwenderbedarfe z. B. bezüglich des Publikationskostenmonitorings als wichtigem Baustein der zu etablierenden Informationsbudgets. Nicht zuletzt möchte der Vortrag die zentralen positiven wie negativen ‚lessons learned‘ aufzeigen und zur Diskussion weiterer konsortialer Handlungsoptionen im Bereich Open Access anregen.

description: Multivariate local linear regression and parametric error correction models are applied to assess price linkages and price transmission patterns between food and energy prices in Spain. Weekly biodiesel, sunflower and crude oil prices observed from November 2006 to October 2010 are used in the empirical analysis. Results suggest the existence of a long-run equilibrium relationship between the three prices studied. Biodiesel is the only variable that adjusts to deviations from this long-run parity. Local linear regression techniques show that the speed of adjustment of biodiesel prices is higher when biodiesel is cheap than when it is expensive. Energy prices are also found to influence sunflower oil prices through the short-run price dynamics.

description: Experimental and field investigations for solution mining processes have improved intensely in recent years. Due to today's computing capacities, three-dimensional simulations of potential salt solution caverns can further enhance the understanding of these processes. They serve as a "virtual prototype" of a projected site and support planning in reasonable time. In this contribution, we present a meshfree Generalized Finite Difference Method (GFDM) based on a cloud of numerical points that is able to simulate solution mining processes on microscopic as well as macroscopic scales, which differ significantly in both the spatial and temporal scale. Focusing on anticipated industrial requirements, Lagrangian and Eulerian formulations including an Arbitrary Lagrangian-Eulerian (ALE) approach are considered.

description: This paper uses repeated cross section data from Norway to compare patterns of inequality in self assessed health and obesity with patterns of inequality in underlying lifestyles central to the production of good health, namely physical activity, non-smoking and diet quality, represented by fish and fruits and vegetables consumption. We estimate a multivariate probit model to study correlates of these lifestyle and health variables, while Gini and concentration indices are being decomposed to identify sources of inequality. Results point towards considerable heterogeneity across the different lifestyle and health variables. Thus, patterns of inequality in health outcomes are not necessarily representative of patterns of inequality in their underlying production factors, including lifestyles. While education is generally found to be an important source of inequality, and in some variables, primarily the health variables, also income, there are several cases in which other factors are much more important in explaining inequality, such as gender in fruits and vegetables eating, age in fish eating, and maternal education in obesity. Assuming that poor health and health inequality should ideally be prevented rather than treated, policies should mainly focus on production factors of health, including lifestyles, rather than final health itself. To be efficient, however, the design of such policies may need to be based on lifestyle-specific knowledge, as suggested by our heterogeneous results.

Subjects: Resource /Energy Economics and Policy

description: Water scarcity and land degradation increases led to a sharp rise in input resource's costs. These developments make it increasingly difficult for agricultural farms to produce according to the demand for food and other commodities, especially owing a rapid population growth. The present study aims to focus on scarce resource use in the agricultural production of the Zarafshan valley by means of the efficiency analysis. A DEA model is estimated to investigate the farm level efficiency levels with respect to the use of the limited resources available to the farmers. By the application of linear programming methods a "best practice frontier is estimated‟, classifying farms on the frontier as efficient and others as inefficient with respect to different scales. Technical and allocative efficiencies are calculated relative to the frontier. Results shows input resources are not used efficiently and a great majority of farms could effectively reduce considerable amounts of input use by still producing the same output.

We will show that distributions with coordinate independent values for information entropy require that the manifold on which the distribution is defined is charted by conjugate pairs (i.e. it is a symplectic manifold). We will also show that further requiring that the information entropy is conserved during the evolution yields Hamilton's equations.

description: The Planning Domain Definition Language (PDDL) is the state-of-the-art language for specifying planning problems in artificial intelligence research. Writing and maintaining these planning problems, however, can be time-consuming and error prone. To address this issue, we present myPDDL-a modular toolkit for developing and manipulating PDDL domains and problems. To evaluate myPDDL, we compare its features to existing knowledge engineering tools for PDDL. In a user test, we additionally assess two of its modules, namely the syntax highlighting feature and the type diagram generator. The users of syntax highlighting detected 36% more errors than non-users in an erroneous domain file. The average time on task for questions on a PDDL type hierarchy was reduced by 48% when making the type diagram generator available. This implies that myPDDL can support knowledge engineers well in the PDDL design and analysis process.

Through computations based on a rigorous time-dependent Green's function approach, we demonstrate that such a mode inevitably generates characteristic image oscillations in two dimensional focusing with even a monochromatic source, which were observed in many numerical simulations, but such oscillations are weak in three dimensional focusing.

description: This paper uses a fundamental Q model of investment to consider the role played by financing frictions in agricultural investment decisions, controlling econometrically for censoring, heterogeneity and errors-in-variables. Our findings suggest that farmer's investment decisions are not driven by market fundamentals. We find some evidence that debt overhang restricts investment but investment is not dependent on liquidity or internal funds. The role of financing frictions in determining investment decisions changes in the post-financial crisis period when debt overhang becomes a significant impediment to farm investment. The evidence suggests that farmers increasingly rely on internal liquidity to drive investment. Finally, we find no evidence that farmers use on-farm capital to fund on-farm investment.

description: This paper evaluates the production and income effects from the adoption of one popular agro-environmental measure, which concerns buffer strips along field edges, on a representative sample of crop farms in Belgium taken from the Farm Accountancy Data Network database. We represent the economic behaviour of each crop farm with a profit-maximisation programming model that embeds an estimated ex-ante flexible cost function. We calibrate the simulation model using the Positive Mathematical Programming approach. Accounting for farm and regional heterogeneity, simulation results show how crop farms may respond differently to incentives for the agroenvironmental measure. Results demonstrate that economic incentives can be an effective mechanism for encouraging uptake of agro-environmental measures and that impacts of agro-environmental measures can vary by farm and region, depending on agronomic conditions and the environmental potential for agro-environmental measure activity.

description: Researchers of today are witnessing a digital and data driven transformation changing the way research is done – and this is especially true for digital humanities. In addition, new regulations on national and international level impose requirements that researchers must adhere to, while the expectations of Open Science and the free sharing of research data is becoming more prominent. In this full-day workshop we will explore hands-on how you as a researcher in digital humanities can more effectively navigate this landscape and learn practical skills for handling your research data from their collection, refinement and analysis to their publication and long term storage and archiving. This course addresses new requirements and guidelines related to the management and sharing of research data: during and after the project’s lifetime. We will consider the planning work associated with research data management as an integral part of project planning. We take a practical approach to solve the data management problem from the perspective of both project managers and project participants. The workshop participants will gain a deeper understanding of what a data management plan is. The workshop also includes a detailed walkthrough of a data management plan, addressing important practical issues in creating one. We will familiarize ourselves with ‘good enough practices’ for data handling and research software development. After the workshop, every participant will go home with a customized guide for research data management they can start implementing in ongoing and planned projects.

description: In this paper, a class of nonlinear driftless control-affine systems satisfying the bracket generating condition is considered. A gradient-free optimization algorithm is developed for the minimization of a cost function along the trajectories of the controlled system. The algorithm comprises an approximation scheme with fast oscillating controls for the nonholonomic dynamics and a model-free extremum seeking component with respect to the output measurements. Exponential convergence of the trajectories to an arbitrary neighborhood of the optimal point is established under suitable assumptions on time scale parameters of the extended system. The proposed algorithm is tested numerically with the Brockett integrator for different choices of generating functions.

description: Path dependence is a phenomenon which can also be observed in agriculture. Especially structures in German dairy farming are very heterogeneous. The abolishment of the milk quota system in 2015 offers opportunities and challenges for dairy farmers at the same time. Our research aim is to find out to what extent a changing policy environment will affect structural change in the dairy sector. Therefore it is interesting to build different scenarios to analyse path dependence, path breaking and path craetion. In this contribution we focus on results from a first workshop in our German study region Altmark. We used participatory methods for the analysis of mechanisms, trends and policy effects in the regional dairy sector. In this first stakeholder workshop we collected different views of stakeholders on dairy farming in the case study region, discussed assumptions of the model AgriPoliS and identified hints for potential scenarios.

This fact exacerbates the global issue of hiring cybersecurity employees with relevant skills. In this paper, we present KYPO4INDUSTRY training facility and a course syllabus for beginner and intermediate computer science students to learn cybersecurity in a simulated industrial environment. The training facility is built using open-source hardware and software and provides reconfigurable modules of industrial control systems. The course uses a flipped classroom format with hands-on projects: the students create educational games that replicate real cyber attacks. Throughout the semester, they learn to understand the risks and gain capabilities to respond to cyber attacks that target industrial control systems. Our described experience from the design of the testbed and its usage can help any educator interested in teaching cybersecurity of cyber-physical systems.

Interference between the undeflected pulsar image and deflected subimages allows single dish interferometry of the interstellar medium with sub-milliarcsecond resolution. We infer the presence of scattering structure(s) similar to those that are thought to cause Extreme Scattering Events in quasar flux monitoring programs: size ~ 0.2 AU (an angular size of 0.1 mas) with an electron density of > 10^3 compared to the warm ionized medium. The deflectors are nearly stationary in a scattering screen that is thin (< 5% of the pulsar-observer distance in extent), is located 70% of the way from the Earth to the pulsar, and has been seen consistently in observations dating back 20 years. The pulsar scans the scattering screen at a velocity of 110 km/s with a detection radius of 15 mas. Pulsar observations such as these -- particularly with a new generation of low-frequency radio telescopes with large collecting areas -- hold promise for improving constraints on the poorly understood physical characteristics and space density of the deflecting structures. Such observations may also prove useful in correcting deviations the deflectors produce in high-precision timing of millarcsecond pulsars.

description: The preservation of digital maps has been a long-term challenge for the cartographic community, GIS industry, and related mapping agencies. As a special type of digital data, digital maps not only contains geospatial datasets, but also requires the metadata and styling information associated with datasets. However, research has shown that most digital mapping archive projects in the world are using the shapefile and GeoTIFF format to store geospatial data, which cannot completely fulfill the principles of digital map preservation. Thus, an alternative method is necessary to satisfy the need for digital map preservation. This thesis proposes a new approach to archive digital maps using GeoPackage format and to disseminate digital maps using vector tile format. For this thesis, a case study was conducted using the Austrian Cartographic Model with national map styling. The new approach allows the archiving and sharing processes to be conducted in a free, cross-platform, and open-source environment using QGIS and Geoserver. In addition, a Python script has been developed to provide a user-friendly interface and to minimize the human effort during the process of embedding metadata. Based on the results from the case study, this thesis proposes an innovative approach to embed relevant metadata for future usage in digital maps using GeoPackage and to embed styling from GeoPackage when distributing digital maps that use vector-tile format. It also shows the possibility of using Python scripts to automate the procedure of embedding relevant information into GeoPackage.

description: Kartenbasierte touristische Location-based Services sind zwar zahlreich vorhanden, wenige bieten allerdings nutzerbasierte und Kontext-abhängige Möglichkeiten. In dieser Arbeit wird die Konzeption einer Open Travel Map vorgestellt und durch eine Implementierung validiert.
description: The overwhelming touristic data collections currently available to any user is a problem of great concern nowadays. Due to the large amounts of information the user has to assess, the process of decision making became more and more time consuming and difficult to complete [20]. In an attempt to overcome this issue, systems that effectively assist users by providing access to relevant information should be developed. With this purpose, there are several applications in the field of tourism that offer detailed travel guides, descriptions of points of interest and even allow users to create their own travel routes. The present thesis focuses on the development of a mobile location based service that assists users in creating and searching for travel routes, the OpenTravelMap platform. In contrast to other existing platforms, the OpenTravelMap platform not only provides tools that facilitate the process of route creation and route search, but also integrates features that aim to enhance these functionalities. These features refer to the connection with other platforms in order to access external resources and a context aware recommender system. The outcome of this thesis, the OpenTravelMap platform, aims to be a worthwhile contribution to the field of tourism in view of the benefits supplied to its users.
Effect of stent marker materials on the localization of cross-sectional images using spiral tomography

description: With the increase in endosseous dental implant placement there is an increasing demand for cross-sectional imaging of the jaws to facilitate treatment planning of the patient. While there are many articles recommending different types of marker materials in guide stents to be used for this imaging, no quantitative comparisons of the efficacy of such materials have been published. The purpose of this study was to compare different types of marker materials for radiographic guide stents for conventional spiral tomography. Differences in the ability of observers to localize cross-sectional images relative to longitudinal images with the different types of markers were determined. Radiographic guide stents for dried human mandibles and one metatarsal bone were fabricated to accept acrylic cylinders with different marker materials in the same relative position. These were imaged using conventional spiral tomography and observers were asked to localize the cross-sectional images on corresponding longitudinal images using the markers as guides. A pilot study confirmed that there were statistically significant differences in the mean absolute error of slice localization by observers for different marker materials. The pilot study also confirmed that any type of marker resulted in much less mean absolute error in slice localization than use of no marker. The definitive study found statistically significant differences in mean error for slice localization not only for different types of markers, but also for the location of the tomographic slice and for the stents made for different bones.

description: A 1972 duality conjecture due to Pietsch asserts that the entropy numbers of a compact operator acting between two Banach spaces and those of its adjoint are (in an appropriate sense) equivalent. This is equivalent to a dimension free inequality relating covering (or packing) numbers for convex bodies to those of their polars. The duality conjecture has been recently proved (see math.FA/0407236) in the central case when one of the Banach spaces is Hilbertian, which - in the geometric setting - corresponds to a duality result for symmetric convex bodies in Euclidean spaces. In the present paper we define a new notion of "convexified packing," show a duality theorem for that notion, and use it to prove the duality conjecture under much milder conditions on the spaces involved (namely, that one of them is K-convex).

description: The structure of a physisorbed sub-monolayer of 1,2-bis(4-pyridyl)ethylene (bpe) on epitaxial graphene is investigated by Low-Energy Electron Diffraction and Scanning Tunneling Microscopy. Additionally, non-equilibrium heat-transfer between bpe and the surface is studied by Ultrafast Low-Energy Electron Diffraction. Bpe arranges in an oblique unit cell which is not commensurate with the substrate. Six different rotational and/or mirror domains, in which the molecular unit cell is rotated by 28{\pm}0.1° with respect to the graphene surface, are identified. The molecules are weakly physisorbed, as evidenced by the fact that they readily desorb at room temperature. At liquid nitrogen temperature, however, the layers are stable and time-resolved experiments can be performed. The temperature changes of the molecules and the surface can be measured independently through the Debye-Waller factor of their individual diffraction features. Thus, the heat flow between bpe and the surface can be monitored on a picosecond timescale. The time-resolved measurements, in combination with model simulations, show the existence of three relevant thermal barriers between the different layers. The thermal boundary resistance between the molecular layer and graphene was found to be 2{\pm}1{\cdot}10-8 K m2 W-1.

description: The impact of group affiliation to agroholdings on enterprise performance in terms of productivity and efficiency is controversially discussed in the literature. However, only few papers evaluate the effects of group membership on the productivity and the efficiency of agricultural enterprises in Russia. The underlying research question of this paper is therefore whether farms that belong to agroholdings perform better than independent farms. We calculate partial land and labor productivity, total factor productivity and technical efficiency scores for the two categories of independent farms and members of agroholdings. In this paper a production function approach is estimated in the framework of stochastic frontier analysis. The results are used to decompose total factor productivity into a scale effect, a technological change effect and a technical efficiency effect. The results show a different trend than observed in previous studies. The growth of agroholdings total factor productivity exceeds by far the development of the independent farms and that group affiliation has a positive impact on the performance of the farm.
The Galactic radial abundance gradients of C, N, O, Ne, S, Cl and Ar from deep spectra of H II regions

description: We present a reassessment of the radial abundance gradients of C, N, O, Ne, S, Cl and Ar in the Milky Way using deep spectra of 33 H II regions gathered from the literature, covering Galactocentric distances from 6 to 17 kpc. The distances of the objects have been revised using Gaia parallaxes. We recalculate the physical conditions and ionic abundances in an homogeneous way using updated atomic data. All the objects have direct determination of the electron temperature, permitting to derive their precise ionic abundances. We analyze and compare different ICF schemes for each element in order to obtain the most confident total abundances. Due to the revised distances, our results do not support previous claims about a possible flattening of the O/H gradient in the inner Galactic disk. We find that the Galactic N/O gradient is rather flat, in contrast to what has been found in other spiral galaxies. The slope of the gradients of some elements is sensitive to the ICF scheme used, especially in the case of Ne. The dispersion around the fit for the gradients of C, N, O, S, Cl and Ar is of the order of the typical uncertainties in the determination of the abundances, implying the absence of significant inhomogeneities in the chemical composition of the ionized gas phase of the ISM. We find flat gradients of log(S/O) and log(Cl/O) and very shallow or flat ones for log(Ne/O) and log(Ar/O), consistent with a lockstep evolution of Ne, S, Cl and Ar with respect to O.
