description: Enhanced geothermal systems (EGS) are an emerging energy technology with the potential to significantly expand the viable resource base for geothermal power generation. Although EGS has traditionally been envisioned as a 'baseload' resource, flexible operation of EGS wellfields could allow these plants to provide load-following generation and long-duration energy storage. In this work we evaluate the impact of operational flexibility on the long-run system value and deployment potential of EGS power in the western United States. We find that load-following generation and in-reservoir energy storage enhance the role of EGS power in least-cost decarbonized electricity systems, significantly increasing optimal geothermal penetration and reducing bulk electricity supply costs compared to systems with inflexible EGS or no EGS. Flexible geothermal plants preferentially displace the most expensive competing resources by shifting their generation on diurnal and seasonal timescales, with round-trip energy storage efficiencies of 59-93%. Benefits of EGS flexibility are robust across a range of electricity market and geothermal technology development scenarios.

Improving aspect mining with program dependencies
Creators: name: Singh, Navjot
Publisher: name: University of British Columbia
Year: 2011

description: Aspect mining is the process of semi-automatically identifying crosscutting concerns in non-aspect oriented code so that they may be refactored into structured aspect oriented code. In this work, we extend work on aspect mining by examining how patterns of control and dataflow can be used as indicators of aspectual (or crosscutting) behavior. We look for indicators of code which could be refactored into aspects with a clear, narrowly defined interface to the code it would advise. We validated the usefulness of our approach by implementing three analyses and examining the results applied to two open-source projects.

description: We develop Johnson noise thermometry applicable to mesoscopic devices with variable source impedance with high bandwidth for fast data acquisition. By implementing differential noise measurement and two-stage impedance matching, we demonstrate noise measurement in the frequency range 120-250 MHz with a wide sample resistance range 30 Ω-100 kΩ tuned by gate voltages and temperature. We employ high-frequency, single-ended low noise amplifiers maintained at a constant cryogenic temperature in order to maintain the desired low noise temperature. We achieve thermometer calibration with temperature precision up to 650 mK on a 10 K background with 30 s of averaging. Using this differential noise thermometry technique, we measure thermal conductivity on a bilayer graphene sample spanning the metallic and semiconducting regimes in a wide resistance range, and we compare it to the electrical conductivity.

description: Ocean warming (OW) is one of the greatest threats to the future of our oceans, emphasizing the critical need to understand its impact on predatory species to safeguard our oceans. The aim of this study was to investigate the response of the fissiparous starfish Coscinasterias tenuispina to acute temperature increases (from 20 to 28°C). Metabolism experiments (O2 consumption) were conducted to compare two contrasting populations: (1) the clonal Mediterranean and (2) the sexual Atlantic population. The different genetic structures of these populations make our study interesting, facilitating a discussion of the implications of genetic diversity in future oceans. Starfish metabolism was measured using an intermittent close respirometer. Our results revealed differences between populations caused by greater energy demand in individuals from the clonal Mediterranean population. Moreover, C. tenuispina tends to decrease its aerobic metabolism when exposed to high temperatures, which could imply a disadvantage in coping with OW. Nonetheless, this species shows high survival rates at high temperatures. These insights contribute to our understanding of how genetic diversity influences the responses of this species to environmental stressors, thereby providing valuable information for marine conservation efforts.

description: We use Time Resolved Correlation (TRC), a recently introduced light scattering method, to study the dynamics of a variety of jammed, or glassy, soft materials. The output of a TRC experiment is cI(t,tau), the time series of the degree of correlation between the speckle patterns generated by the light scattered at time t and t+tau. We characterize the fluctuations of cI by calculating their Probability Density Function, their variance as a function of the lag tau, and their time autocorrelation function. The comparison between these quantities for a Brownian sample and for jammed materials indicate unambiguously that the slow dynamics measured in soft glasses is temporally heterogeneous. The analogies with recent experimental, numerical and theoretical work on temporal heterogeneity in the glassy dynamics are briefly discussed.

description: Economic development for remote Indigenous communities cannot be understood unless the relative importance of customary activity, potentially enhanced by native title legal rights in resources, is recognised. The present article uses a three‐sector hybrid economy framework, rather than the usual two‐sector private (or market) and public (or state) model to more accurately depict the Indigenous economy. Examples are provided of the actual and potential significance of the customary sector of the hybrid economy. Focusing on the concepts of property and institutions, it is demonstrated that significant local, regional, and national benefits are generated by the Indigenous hybrid economy. A role is foreshadowed for resource economists and the New Institutional Economics in quantifying these benefits, including positive externalities, so that they might be more actively supported by the state.

description: Dieser Beitrag befasst sich mit dem Einfluss der Transportwürdigkeit nachwachsender Rohstoffe auf die Rohstoffwahl von Biogasanlagen. Dabei wird die Rohstoffversorgung in Abhängigkeit der Transportentfernung der Rohstoffe optimiert. Hierfür wird dasModell der Thünenschen Ringe in einigen Punkten angepasst und auf die Rohstoffversorgung von Biogasanlagen angewendet. Neben den Mengen- und Energieerträgen der nachwachsenden Rohstoffe sowie deren Bereitstellungskosten spielt hierbei auch die Wirtschaftlichkeit der Anlage eine Rolle. Es zeigt sich, dass Silomais auch bei mittleren Transportentfernungen der vorteilhafteste nachwachsende Rohstoff ist. Bei höheren Transportentfernungen ist dagegen der transportwürdigere Winterweizen besser geeignet. Eine Untersuchung der Beschaffungsgebietsgröße der Rohstoffe zeigt, dass auch deutlich größere Biogasanlagen als der heutige Stand der Technik ausschließlich auf Silomais als nachwachsenden Rohstoff zurückgreifen würden. This paper discusses how differences in transport costs of energy crops affect the choice of feedstock used in biogas production. This is done by optimizing feedstock demand subject to transportation distances of the different crops. For this a von Thuenen type model is applied to the feedstock demand of biogas plants. In addition to yields in terms of quantity and energy concerning the different crops and the costs of having them available, the profitability of the fermentation plant must be considered. It is shown that silage maize is the most profitable crop for medium distances, but gives way to winter wheat as distances increase. Our analysis suggests that even bigger plants than today can be sustained exclusively with silage maize.

description: We present a three-dimensional metric affine theory of gravity whose field equations lead to a connection introduced by Schrödinger many decades ago. Although involving nonmetricity, the Schrödinger connection preserves the length of vectors under parallel transport, and appears thus to be more physical than the one proposed by Weyl. By considering solutions with constant scalar curvature, we obtain a self-duality relation for the nonmetricity vector which implies a Proca equation that may also be interpreted in terms of inhomogeneous Maxwell equations emerging from affine geometry.

description: The Byzantines' skill in diplomacy helped the Empire survive during the Middle Ages. Wanting to extend their sphere of influence to the Serbs, the Byzantines used Christianity, civilization and the policy of marriages between purple-born princesses and Serbian rulers as means of their diplomacy. The purpose of this paper is, through the study of the conclusion of these diplomatic marriages, to show how, in addition to the alliances they created between the two states, they gave the princesses the opportunity to pass on the Byzantine culture, but also to influence politics and cultural life of the Serbian people.

description: Mit 79% waren Smartphones 2016 die am häufigsten genutzten Geräte für den Internetzugriff. Schnelle Datenverbindungen selbst in abgelegenen Regionen, steigende Rechenleistung und Displaygrößen ermöglichen eine komfortable Nutzererfahrung. Mobile Visualisierungen, welche von diesen Umständen profitieren, sind jedoch heutzutage kaum verbreitet. Probleme von Visualisierung auf mobilen Geräten sind die begrenzte Displaygröße und die teilweise ungenaue Toucheingabe. Vorteile mobiler Geräte sind deren große Verbreitung und eine breite Palette an eingebauten Sensoren und Eingabemöglichkeiten. Das macht mobile Geräte wie Smartphones besonders geeignet für den Einsatz im Museum. Dabei ist es notwendig, die Bedürfnisse von Gelegenheitsnutzern zu berücksichtigen und geeignete Visualisierungstechniken zu finden. Die vorliegende Diplomarbeit gibt einen breiten Überblick des State of the Art mobiler Visualisierungen und beschreibt den Vorgang vom Design, der Implementierung bis hin zur Evaluation der Visualisierung einer Museumssammlung. Dazu wird auf die Sammlung des Museums für moderne Kunst mumok über das Open Data Portal Österreich zugegriffen. Diese Daten werden mithilfe von D3.js, Google Maps und ngx-charts visualisiert. Für das Frontend der Applikation wird das mobile Framework Ionic benutzt. Zum Schluss wurde die mobile Anwendung mit 21 Teilnehmern im mumok getestet.
description: With 79%, smartphones were the most used devices for accessing the internet in the EU in 2016. High-speed mobile data connectivity reaches even remote locations. Increasing computational power and display size provides users a comfortable user experience. However, mobile visualizations which profit from those circumstances are hardly widespread these days. Problems of visualizations on mobile devices are the limited screen size and inexact touch input. Benefits of mobile devices are the high availability and the broad palette of built-in sensors and input options. This might make mobile devices, for example, smartphones, great devices in the museum context. Keeping the needs of casual museum visitors in mind when finding appropriate visualization techniques is a critical task. The present work gives a broad overview of the state of the art of mobile visualizations and the design, implementation, and evaluation of a visualization of an art museum’s collection. Therefore, the collection of the museum of modern art mumok located in Vienna is accessed through the Open Data Portal Österreich. This data is visualized with the libraries D3.js, Google Maps and ngx-charts. For the frontend of the application, the mobile framework Ionic is used. At the end, the application was evaluated in mumok with 21 participants.
On the presence of Echinus melo Lamarck, 1816 (Echinodermata: Echinidae) in the Sidi-Medjdoub area (Mostaganem, Western Algerian coast)

description: Echinoidea are an important class of echinoderms, represented approximately by 33 genera, including the genus Echinus characterized by a swollen, more or less globose test. In the Mediterranean, the genus Echinus is represented by only one species, Echinus melo Lamarck 1816, which is very rarely recorded in the Mediterranean Sea. This species is most often confused with Echinus acutus now revised as Gracilechinus acutus (Lamarck, 1816). One individual of Echinus melo was found in a batch of invertebrates collected as bycatch from artisanal fisheries in the Sidi-Medjdoub region (Mostaganem, Algeria) at a depth of 74 m. The detailed study of the morphological characters and pedicellariae allowed us to identify it and report it for the first time on the Algerian west coast.

description: In diesem Artikel wird ein semi-parametrisches Matching-Verfahren (Propensity Score Matching) verwendet, um die Effekte von Agrarumweltmaßnahmen und der Ausgleichszulage für benachteiligte Gebiete in Deutschland auf den Faktoreinsatz (Boden, Arbeit, Kapital, Vieh, Pflanzenschutz- und Düngemittel) und den Umsatz zu analysieren. Die Ergebnisse zeigen einen signifikant positiven Effekt beider Programme auf das betriebliche Flächenwachstum (insbesondere auf Grünland), infolgedessen sich die Viehbesatzdichte verringert. Die Teilnahme an Agrarumweltmaßnahmen bewirkt darüber hinaus eine signifikante Verringerung der Düngemittelausgaben je Hektar. Für beide Programme ist kein signifikanter Effekt auf den betrieblichen Umsatz festzustellen. Die Stärke der Programmeffekte nimmt mit zunehmender Höhe der je Hektar erhaltenen Programmzahlungen zu. The paper applies a semi-parametric matching approach (propensity score matching) to evaluate the effects of agri-environment (AE) programs and the less-favoured area (LFA) scheme on input use (land, labour, capital, livestock, fertilizer and pesticides) and farm output of individual farms in Germany. The analysis reveals a positive and significant effect of both farm programs on the area under cultivation, in particular on grassland, resulting in a decrease of cattle livestock density. Furthermore, participation to AE programs significantly reduced the purchase of fertilisers. For both farm programs, no significant effect on farm sales is observed. Furthermore, the magnitude of program effects increases along with increasing program payments.

description: In order to reconstruct the morphology, behavior and environment of fossil organisms, paleontologist often utilize recent data on comparable organisms in the present. This source of information is either gleaned directly from the biological literature or investigated by paleontologist themselves when specific questions not covered by biologist need to be addressed. Two themes of especial importance for echinoid paleontologist are addressed in this review are: 1) evaluating processes affecting preservation and resulting taphonomic gradients of echinoid taxa, 2) direct observations of species interactions such as predation and bioinfestation including encrustation and bioerosion. How recent data is used to interpret fossil remains are shown in three examples comparing recent and fossil taxa. The recent echinoids are derived from the Red Sea and Mediterranean. Fossil echinoid taxa displaying various preservation features are taken from the Cenozoic rocks of Sardinia where both regular and irregular echinoids are present from different paleoenvironmental settings. Finally, the scope for future studies involving actualistic studies and their paleontological applications is given.

description: The brittle star Amphiura filiformis is a keystone species within the burrowing fauna assemblage in the fine, muddy sediments along the European coasts. With high regeneration and bioluminescence capabilities, it species emerged as a model species for many studies. However, only a few studies have investigated the cellular components of its coelomic fluid, which play roles in immunity and metabolite transport. The present study provides a detailed morphological description of the different perivisceral coelomocytes found in the brittle star A. filiformis, including the cell proportions and concentrations. For this purpose, we present a simple method for collecting coelomic circulating cells from small echinoderms with a limited volume of perivisceral fluid, using a needle to inject artificial seawater in the perivisceral coelom followed by an immediate recovery of the fluid containing coelomocytes. Six cell types were identified based on optical and scanning electron microscopy. Morphological similarities with coelomocytes in other brittle star and echinoderm species are discussed. Moreover, the involvement of this coelomic fluid in the transfer of the luminous substrate, coelenterazine, from the stomach content to photogenic sites is investigated, adding a step towards the understanding of this brittle star bioluminescence.

description: In the present investigation we use observational data of $ f σ_ {8} $ to determine observational constraints in the plane $(Ω_{m0},σ_{8})$ using two different methods: the growth factor parametrization and the numerical solutions method for density contrast, $δ_{m}$. We verified the correspondence between both methods for three models of accelerated expansion: the $ΛCDM$ model, the $ w_{0}w_{a} CDM$ model and the running cosmological constant $RCC$ model. In all case we consider also curvature as free parameter. The study of this correspondence is important because the growth factor parametrization method is frequently used to discriminate between competitive models. Our results we allow us to determine that there is a good correspondence between the observational constrains using both methods. We also test the power of the $ fσ_ {8} $ data to constraints the curvature parameter within the $ ΛCDM $ model. For this we use a non-parametric reconstruction using Gaussian processes. Our results show that the $ fσ_ {8}$ data with the current precision level does not allow to distinguish between a flat and non-flat universe.

description: In dem Beitrag wird am Beispiel von Primärdaten für landwirtschaftliche Betriebe in Schleswig-Holstein der Frage nach den Bestimmungsgründen für Aufnahme, Umfang und Diversifikation der außerbetrieblichen Einkommensquellen nachgegangen. Für die Messung der farmspezifischen Diversifikation wurde auf das Konzept von Gollop und Monahan zurückgegriffen. Die Zusammenhänge zwischen diesem Ausmaß und anderen betrieblichen und hauswirtschaftlichen Eigenschaften wurden mittels eines ökonometrischen Modells untersucht. Die Ergebnisse deuten darauf hin, dass die Steigerung des Einkommens bzw. das Streben nach optimaler Ressourcennutzung bei den Diversifikationsentscheidungen im Vordergrund stehen. Dabei stellt die Risikominimierung ein eher nachrangiges Ziel für die Aufnahme außerbetrieblicher Aktivitäten dar. Der Zugang zu Ressourcen (Arbeit, Kapital) ist diesbezüglich eine wesentliche Voraussetzung für die Erschließung und den Umfang alternativer Einkommensquellen. Die Qualifikation des Betriebsleiters spielt eine wichtige Rolle. Mit steigendem Ausbildungsgrad erhöht sich die Diversifikationsneigung. Diese und weitere Erkenntnisse sind bei der Gestaltung von effizienten Politikmaßnahmen relevant, um die verschiedenartigen Bedürfnisse der landwirtschaftlichen Haushalte zu berücksichtigen. This article investigates the degree of income diversification and identifies its determinants in a selected German Land, Schleswig-Holstein. We apply the concept of Gollop and Monahan to measure the farm’s specific diversification. To analyze the relationships between income diversification and other farm’s and household’s specific factors, an econometric model has been estimated based on a comprehensive survey data. The results show that the main economic incentive for a farm’s diversification is the expected income increase, whereas risk minimization is less important. The access to resources (labor, capital) is an important requirement for tapping alternative economic activities. The formal agricultural education of the farmer is a significant factor: The higher his education the stronger is the tendency towards diversification. These findings are relevant for the design of agricultural policy measures which aim at explicitly meeting the heterogeneous needs of rural households.

description: The $N=Z=36$ nucleus $^{72}$Kr has been studied by inelastic scattering at intermediate energies. Two targets, $^{9}$Be and $^{197}$Au, were used to extract the nuclear deformation length, $δ_\text{N}$, and the reduced $E2$ transition probability, $B(E2)$. The previously unknown non-yrast $2^+$ and $4^+$ states as well as a new candidate for the octupole $3^-$ state have been observed in the scattering on the Be target and placed in the level scheme based on $γ-γ$ coincidences. The second $2^+$ state was also observed in the scattering on the Au target and the $B(E2;\;2^+_2 \rightarrow 0^+_1)$ value could be determined for the first time. Analyzing the results in terms of a two-band mixing model shows clear evidence for a oblate-prolate shape coexistence and can be explained by a shape change from an oblate ground state to prolate deformed yrast band from the first $2^+$ state. This interpretation is corroborated by beyond mean field calculations using the Gogny D1S interaction.

description: In diesem Beitrag wird mit einer qualitativen Längsschnittuntersuchung von 74 österreichischen Biobetrieben untersucht, welche Haushaltsstrategien zu einem langfristigen Überleben im Agrarstrukturwandel führen. Zu diesem Zweck werden die Haushaltsstrategien der Bauernfamilien den Entwicklungsrichtungen der Betriebe zugeordnet und an die sozialwissenschaftliche Debatte der Betriebsentwicklung bäuerlicher Familienbetriebe angeknüpft. Die Ergebnisse zeigen, dass im Beobachtungszeitraum von 14 Jahren in 35 untersuchten Biobetrieben Haushaltsstrategien verfolgt wurden, die zu einer Professionalisierung führten, während sich 18 Betriebe auf dem Rückzug aus der Landbewirtschaftung befanden. Acht Biobetriebe wiesen eine stabile Reproduktion, 13 eine wechselhafte Entwicklung auf. Für die zukünftige Entwicklung der Untersuchungsbetriebe kann davon ausgegangen werden, dass jene mit Professionalisierung mit höherer Wahrscheinlichkeit in der nächsten Generation weitergeführt werden. Ob diese dann weiter professionalisiert werden, hängt wesentlich von der Bedeutung der landwirtschaftlichen Erwerbstätigkeit im Berufsleben der Bauernfamilien insgesamt ab. Based on a dataset of a qualitative longitudinal study of two serial in-depth interviews of 74 Austria farming families engaged in organic farming, we analyse organic farming families´ household strategies for a growth of their farming operation change in agriculture. The results are discussed in light of the social science debate on farm development. Over the study period of 14 years the household strategies of 35 farming families led to professionalization in farming, while the household strategies of 18 families led to disengagement from farming. Eight farms showed a stable economic development and 13 an unsteady direction of farm development. Our results suggest, that professionalized farms are more likely survive economically. Whether professionalization in farming will continue depends on the importance of farming in the overall professional life of the families.
Failure recovery with priority progress multicast
Creators: name: Han, Jung-Rung
Publisher: name: University of British Columbia
Year: 2011

description: This thesis sets out to gauge the strength of single tree based multicast video streaming systems in the presence of network failures. We have implemented failure recovery and improved multicast capabilities for the QStream video streaming system. Nodes in a multicast tree exchange small size information with each other whenever changes to the tree take place. Such information allows a node to determine a suitable replacement before its parent fails. We believe the benefits of the tree-based systems are underrated in the recent movement towards graph or multisource methods for multicast. The argument for graph methods is superior innate fault tolerance and high bandwidth utilization. In the worst case, we will establish a more realistic benchmark for tree-base multicast system to put in perspective of the benefit of graph. In the best case, we can show that trees can be repaired efficiently and quickly, without invoking the complexity of a graph system, contradicting somewhat the common perception that a single tree multicast in essence has poor ability to recover from failures. Quick and scalable failure recovery functionality can also become the basis of self-adjusting tree techniques to maximize bandwidth in future research.

description: Spatially resolved neutron diffraction as a function of crystal depth in Pb(Mg$_{1/3}$Nb$_{2/3}$)O$_{3}$ reveals the presence of a distinct near-surface region. A dramatic change in both the lattice constant and the Bragg peak intensity as a function of crystal depth is observed to occur in this region over a length scale $\sim$ 100 $μ$m. This confirms a previous assertion, based on a comparison between high-energy x-rays and neutrons, that such a near surface region exists in the relaxors. Consequences to both single crystal and powder diffraction measurements and previous bulk neutron diffraction measurements on large single crystals are discussed.

description: Σκοπός της παρούσας βιβλιογραφικής ανασκόπησης είναι η διαχείριση των σεξουαλικών προβλημάτων που αντιμετωπίζουν οι έφηβοι με εγκεφαλική παράλυση καθώς και η αναγνώριση και η μελέτη των ιδιαιτεροτήτων αναφορικά με την εγκεφαλική παράλυση και την αναπτυσσόμενη σεξουαλικότητα τους. Θα γίνει μια προσπάθεια αναζήτησης τρόπων αντιμετώπισης αυτών για την ανάπτυξη και την κοινωνικοποίησης τους άλλα και τη διεκδίκηση των δικαιωμάτων και αναγκών στα σεξουαλικά ζητήματα και στην έκφραση τους. Οι έννοιες που αφορούν την παρούσα βιβλιογραφική ανασκόπηση, είναι o ορισμός της εγκεφαλικής παράλυσης και επιγραμματικά οι κατηγορίες της, τα προβλήματα σεξουαλικότητας των έφηβων με εγκεφαλική παράλυση και oι τρόποι αντιμετώπισης αυτών. Θα συζητηθούν προβλήματα σεξουαλικότητας των έφηβων με εγκεφαλική παράλυση, όπως η πρώιμη ήβη, η σεξουαλική ωρίμανση, ζητήματα σεξουαλικής ικανότητας και στην αισθητικότητα, αυνανισμό, συνουσία, εγκυμοσύνη, αντισύλληψη, και σεξουαλικά μεταδιδόμενα νοσήματα. Τo σεξουαλικό ενδιαφέρον και o αυνανισμός είναι πτυχές της σεξουαλικής ανάπτυξης που τυπικά προηγούνται της σεξουαλικής δραστηριότητας με έναν σύντροφο. Αυτό δείχνει ότι τα άτομα γενικά εξερευνούν τη σεξουαλικότητα τους πριν εμπλακούν σε σεξουαλικές εμπειρίες με άλλους. Τέλος, θα προταθούν τρόποι αντιμετώπισης προβλημάτων στο πλαίσιο της σεξουαλικότητας, που προκύπτουν από την ιδιαίτερη συνθήκη της εγκεφαλικής παράλυσης, και αφορούν στην εκπαίδευση τόσο των ιδίων όσο και των γονέων, δασκάλων και θεραπευτών.
description: The purpose of this literature review is the management of the sexual problems faced by adolescents with cerebral palsy as well as the recognition and study of the peculiarities regarding cerebral palsy and their developing sexuality. Also, an attempt will be made to search for ways to deal with them for their development and socialization, as well as the assertion of rights and needs in sexual matters and their expression. The concepts that concern the present bibliographic review are the definition of cerebral palsy and its categories epigrammatically, the sexuality problems of teenagers with cerebral palsy and the ways of dealing with them. We will discuss sexuality problems of adolescents with cerebral palsy, such as early puberty, sexual maturation, issues of sexual ability and sensuality, masturbation, intercourse, pregnancy, contraception, sexually transmitted diseases. Finally, ways of dealing with problems in the context of sexuality, resulting from the special condition of cerebral palsy, will be proposed, and they concern the education of both the students themselves and their parents, teachers and therapists.
Electroweak supersymmetric effects on high energy unpolarized and polarized single top production at LHC

description: We consider various processes of single top production at LHC in the theoretical framework of the MSSM and examine the role of the supersymmetric electroweak one-loop corrections in a special moderately light SUSY scenario, in an initial parton-pair c.m. high energy range where a logarithmic asymptotic expansion of Sudakov type can be used. We show that the electroweak virtual effects are systematically large, definitely beyond the relative ten percent size, particularly for a final $tH^-$ pair where a special enhancement is present. We show then in a qualitative way the kind of precision tests of the model that would be obtainable from accurate measurements of the energy distributions of the various cross sections and of the top polarization asymmetries.

The Effectiveness of Interactive Visualization Techniques for Time Navigation of Dynamic Graphs on Large Displays

description: Dynamic networks can be challenging to analyze visually, especially if they span a large time range during which new nodes and edges can appear and disappear. Although it is straightforward to provide interfaces for visualization that represent multiple states of the network (i.e., multiple timeslices) either simultaneously (e.g., through small multiples) or interactively (e.g., through interactive animation), these interfaces might not support tasks in which disjoint timeslices need to be compared. Since these tasks are key for understanding the dynamic aspects of the network, understanding which interactive visualizations best support these tasks is important. We present the results of a series of laboratory experiments comparing two traditional approaches (small multiples and interactive animation), with a more recent approach based on interactive timeslicing. The tasks were performed on a large display through a touch interface. Participants completed 24 trials of three tasks with all techniques. The results show that interactive timeslicing brings benefit when comparing distant points in time, but less benefits when analyzing contiguous intervals of time.

description: A stochastic Navier-Stokes equation with space-time Gaussian white noise is considered, having as infinitesimal invariant measure a Gaussian measure μ_ν whose covariance is given in terms of the enstrophy. Pathwise uniqueness for μ_ν-a.e. initial velocity is proven for solutions having μ_ν as invariant measure.

description: I briefly review CP violation in the B system, concentrating on B -> pi K decays. I discuss how to deal with electroweak-penguin contributions to these decays using flavour SU(3). With these, I show that the entire unitarity triangle can be extracted from measurements of B -> pi K decays. Finally, I examine the signals for new physics in these decays and the possibilities for measuring them.

description: Diese Untersuchung befasst sich mit der Rolle der Landwirtschaft im Bereich der ländlichen Daseinsversorgung. Zum einen wird untersucht, ob und wenn ja, inwieweit der landwirtschaftliche Sektor von dem demographischen Wandel tangiert wird. Zum anderen wird analysiert, in welchem Rahmen landwirtschaftliche Betriebe Aufgaben der öffentlichen Daseinsvorsorge schon unternehmen bzw. künftig unternehmen können, die die Kommunen aus finanziellen bzw. organisatorischen Gründen nicht mehr in der Lage sind anzubieten. In der Region Altmark wurden im Jahr 2011 Experteninterviews mit 137 politischen, wirtschaftlichen und kulturellen Entscheidungsträgern sowie im Jahr 2012 Interviews mit 134 landwirtschaftlichen Betriebsleitern durchgeführt. Neben diesen Interviews wurden statistische Daten sowie die relevante Sekundärliteratur analysiert. Die wichtigsten Ergebnisse lassen sich wie folgt zusammenfassen. Die politischen, wirtschaftlichen und kulturellen Akteure der Altmark haben erkannt, dass die Bevölkerungsentwicklung ein dominanter Standortfaktor ihrer Region ist. Auch die landwirtschaftlichen Betriebsleiter nehmen die Auswirkungen des demographischen Wandels sowohl in der Region als auch auf den Betrieben, vor allem bei der Rekrutierung qualifizierter Arbeitskräfte, stärker wahr . Die Befragungsergebnisse unterstreichen sehr deutlich, dass landwirtschaftliche Betriebe - häufig sogar ohne Vergütung - einen Beitrag zur öffentlichen Daseinsvorsorge leisten. Die Gründe für diese Übernahme sind nicht betriebswirtschaftlich zu erklären, da die meisten Betriebe hierfür gar nicht, und wenn, dann nur sehr bescheiden vergütet werden. Der Hauptgrund liegt in der emotional-sozialen Verbundenheit zu der heimatlichen Region, also einer engen Bindung der landwirtschaftlichen Betriebe mit dem ländlichen Raum und seinen Bewohnern. Versicherungstechnische Regelungen wirken für manche Betriebsleiter als ein Hemmnis für die Übernahme von Aufgaben der öffentlichen Daseinsvorsorge.
