Here we show that the analysis of current-voltage curves of organic solar cells under illumination with the Shockley equation results in values for ideality factor, photo-current and parallel resistance, which lack physical meaning. Drift-diffusion simulations for a wide range of charge-carrier mobilities and illumination intensities reveal significant carrier accumulation caused by poor transport properties, which is not included in the Shockley equation. As a consequence, the separation of the quasi Fermi levels in the organic photoactive layer (internal voltage) differs substantially from the external voltage for almost all conditions. We present a new analytical model, which considers carrier transport explicitly. The model shows excellent agreement with full drift-diffusion simulations over a wide range of mobilities and illumination intensities, making it suitable for realistic efficiency predictions for organic solar cells.

Group CY - London ER - TY - BOOK A1 - Wätzoldt, Sebastian A1 - Giese, Holger T1 - Modeling collaborations in self-adaptive systems of systems BT - terms, characteristics, requirements, and scenarios N2 - An increasing demand on functionality and flexibility leads to an integration of beforehand isolated system solutions building a so-called System of Systems (SoS). Furthermore, the overall SoS should be adaptive to react on changing requirements and environmental conditions. Due SoS are composed of different independent systems that may join or leave the overall SoS at arbitrary point in times, the SoS structure varies during the systems lifetime and the overall SoS behavior emerges from the capabilities of the contained subsystems. In such complex system ensembles new demands of understanding the interaction among subsystems, the coupling of shared system knowledge and the influence of local adaptation strategies to the overall resulting system behavior arise. In this report, we formulate research questions with the focus of modeling interactions between system parts inside a SoS. Furthermore, we define our notion of important system types and terms by retrieving the current state of the art from literature. Having a common understanding of SoS, we discuss a set of typical SoS characteristics and derive general requirements for a collaboration modeling language. Additionally, we retrieve a broad spectrum of real scenarios and frameworks from literature and discuss how these scenarios cope with different characteristics of SoS. Finally, we discuss the state of the art for existing modeling languages that cope with collaborations for different system types such as SoS. N2 - Steigende Anforderungen zum Funktionsumfang und der Flexibilität von Systemen führt zur Integration von zuvor isolierten Systemlösungen zu sogenannten System of Systems (SoS). Weiterhin sollten solche SoS adaptive Eigenschaften aufweisen, die es ihm ermöglichen auf sich ändernde Anforderungen und Umwelteinflüsse zu reagieren. Weil SoS aus unterschiedlichen, unabhängigen Subsystemen zusammengesetzt sind, die wiederum das übergeordnete SoS zu beliebigen Zeitpunkten erweitern oder verlassen können, ist das SoS durch eine variable Systemstruktur gekennzeichnet. Weiterhin definieren sich der Funktionsumfang des SoS und dessen Potenzial aus den enthaltenen Subsystemen. Solche komplexen Systemzusammenstellungen erfordern neue Untersuchungstechniken, um die Interaktion der einzelnen Subsysteme, die Kopplung von geteilten Daten und den Einfluss von lokalen Adaptionsstrategien auf das Gesamtsystem besser verstehen zu können. In diesem Bericht formulieren wir aktuelle Forschungsfragen mit dem Fokus auf der Modellierung von Interaktionen zwischen verschiedenen Systemteilen innerhalt eines SoS. Weiterhin definieren wir wichtige Systemtypen und Begriffe aus diesem Bereich durch das Zusammentragen aktueller Literatur. Nachdem wir ein gemeinsames Verständnis über SoS geschaffen haben, leiten wir typische SoS Eigenschaften und allgemeine Anforderungen für eine Modellierungssprache für Kollaborationen ab. Zusätzlich führen wir eine Literaturstudie durch, in der wir ein breites Spektrum von realen Szenarios und existierenden Frameworks zusammentragen, an denen wir die aufgezeigten SoS Eigenschaften diskutieren. Abschließend beschreiben wir den Stand der Wissenschaft bezüglich existierender Modellierungssprachen, die sich mit Kollaborationen in verschiedenen Arten von Systemen, wie SoS, beschäftigen.

From the large variety of existing polymerization methods on the one hand and strategies for grafting onto nanoparticle surfaces on the other hand, the combination of grafting-from with controlled radical polymerization (CRP) techniques has turned out to be the best suited for synthesizing these well-defined core/shell nanohybrids and is known as surface-initiated CRP. Most common among these are surface-initiated atom transfer radical polymerization (ATRP), surface-initiated reversible addition-fragmentation chain transfer (RAFT) polymerization, and surface-initiated nitroxide-mediated polymerization (NMP). This review highlights the state of the art of growing polymers from nanoparticles using surface-initiated CRP techniques. We focus on mechanistic aspects, synthetic procedures, and the formation of complex architectures as well as novel properties. From the vast number of examples of nanoparticle/polymer hybrids formed by surface-initiated CRP techniques, we present nanohybrid formation from the particularly important and most studied silica nanoparticles, gold nanocrystals, and proteins which can be regarded as bionanoparticles.

Several studies indicate that IAT scores can be faked on instruction. But fully or semi-instructed research scenarios might not properly reflect what happens in more realistic situations, when participants secretly decide to try faking the test. The present study is the first to investigate IAT faking when there is only an implicit incentive to do so. Sixty-five athletes (22.83 years +/- 2.45; 25 women) were randomly assigned to an incentive-to-fake condition or a control condition. Participants in the incentive-to-fake condition were manipulated to believe that athletes with lenient doping attitudes would be referred to a tedious 45-minute anti-doping program. Attitudes were measured with the pictorial doping brief IAT (BIAT) and with the Performance Enhancement Attitude Scale (PEAS). A one-way MANOVA revealed significant differences between conditions after the manipulation in PEAS scores, but not in the doping BIAT. In the light of our hypothesis this suggests that participants successfully faked an exceedingly negative attitude to doping when completing the PEAS, but were unsuccessful in doing so on the reaction time-based test. This study assessed BIAT faking in a setting that aimed to resemble a situation in which participants want to hide their attempts to cheat. The two measures of attitude were differentially affected by the implicit incentive. Our findings provide evidence that the pictorial doping BIAT is relatively robust against spontaneous and naive faking attempts. (B) IATs might be less prone to faking than implied by previous studies.

Dabei wurden zwei zentrale Fragestellungen thematisiert. Erstens: Führen PPP­Projekte zu einer Verschuldung der öffentlichen Hand und sind sie entsprechend bei den Berechnungen der Konvergenzkriterien bzw. der Schulden- und Neuverschuldungsquoten zu berücksichtigen? Die zu prüfende Arbeitshypothese geht von einer Verschuldung der öffentlichen Hand in Folge von PPP-Projekten aus. Zweitens: Unterstellt wird eine bedeutsame Funktion von PPP für die Infrastrukturfinanzierung, wobei im Sinne einer Effizienzsteigerung die Passgenauigkeit beziehungsweise Konsistenz der haushaltsrechtlichen Regelungen mit den regulatorischen Vorgaben für die Kapitalgeber von PPP-Projekten analysiert wird. Diese Schnittstelle und die zur Generierung günstiger („kommunalähnlicher") Finanzierungskonditionen notwendigen staatlichen Garantien bei PPP drängt geradezu zu einem ordnungspolitischen Vergleich von Ansätzen bzw. Projekten im Bereich PPP und in Cash-Flow-Kalkülen. Die Arbeit führt mit einem gewissen gesamtwirtschaftlichen Fokus der PPP tief in die Analyse des Kapitalmarktes und der Bankenregulierung. Es erfolgt ein Vergleich der gedeckten Refinanzierungsinstrumente für PPP, die durch Forderungen besichert sind (Asset Backed Securities) und solche, die beispielsweise durch Forderungen gegen die öffentliche Hand besichert sind (Covered Bonds). Letztere können auch grundpfandrechtlich gesichert sein. Hier setzt der Verfasser später seine Skizze eines „Infrastructure Covered Bonds" für die Finanzierung notwendiger Infrastrukturmaßnahmen nicht nur in Deutschland an, wobei das Wertpapier hier ausschließlich zur Finanzierung der Infrastruktur bei einem entsprechend neu zuschaffenden (Deckungs-) Registers begeben werden wird. N2 - This thesis analyzes the financing models of public-private partnership projects (PPP) and their refinancing by the investor. Two central issues were addressed. First: Do PPP projects lead to public debt and are they to be taken into consideration for the calculations of the convergence criteria, respectively the debt and debt ratios? The working hypothesis to be verified is based on the public debt as a result of PPP projects. Second: It is assumed that PPP are an important feature for infrastructure financing, with the purpose of increasing efficiency the fit or consistency of budgetary regulations are being analyzed with the regulatory requirements for capital providers of PPP projects. This interface and the necessary government guarantees for PPP to generate favorable ("Municipal similar") financing conditions urges towards a policy comparison of PPP approaches or PPP projects and cash flow calculi. The thesis will lead with a certain macroeconomic focus of PPP deep into the analysis of the capital market and banking regulation. A comparison is made of covered funding instruments for PPP, which are secured by receivables (asset backed securities) and those which are secured, for example, by claims against the public sector (covered bonds). The bond can also be secured by mortgage. This is where the author will introduce his sketch of "Infrastructure covered bonds" for the financing of infrastructure projects not only in Germany, while the securities will be emitted by a corresponding new-to-be-created (coverage) register exclusively to finance infrastructure.

The symmetry of the closed form is determined by the WoodWard Hoffinann rules according to which the reaction proceeds by corirotatory rotation -in that case. Here, we show by a cOrnbined approach of scanning tunneling microscopy (STM) and density functional theory (DFT) calculations that the Open isomer of 4,4'-(4,4'-(perfluorocydopent-1-ene-1,2-diyl)bis(5-methyl-thiophent-4,2,4-dipyridine) (PDTE) retains its open form upon adsorption on a Ag(111) surface. It caribe switched into a closed form, which we identify as the digrotatOly cydization product, by controlled manipulation 'With the STM tip, Evidence of an electric-field dependent switching-process 'is interpreted on the basis of a Simple electroStatic Model, which suggests that the reaction proceedS via an "upright" intermediate state. This pathway thus strongly differs from the switching reaction in solution.

Randomized, controlled trial on chronic nonspecific low back pain JF - Der Schmerz : Organ der Deutschen Gesellschaft zum Studium des Schmerzes, der Österreichischen Schmerzgesellschaft und der Deutschen Interdisziplinären Vereinigung für Schmerztherapie N2 - Back pain is a complex phenomenon that goes beyond a simple medical diagnosis. The aetiology and chronification of back pain can be best described as an interaction between biological, psychological, and social processes. However, to date, multimodal prevention and intervention programs for back pain that target all three aetiological factors have demonstrated limited effectiveness. This lack of supportive evidence for multimodal programmes in the treatment of back pain could be due to the fact that few programs are suitable for long-term and unsupervised use in everyday life. Moreover, in combining the elements from various therapies, little attention has been paid to the mechanisms underlying the synergistic effects of the separate components. In this contribution, we will describe the development of a new multimodal intervention for back pain that set out to address these limitations. To this end, the biological elements of neuromuscular adaptation is supplemented with cognitive behavioral and psychophysiological techniques in an intervention that can be followed at home as well as in clinics, and that is suitable for all grades of pain. The efficacy of this intervention will be tested in a multicentric randomized controlled longitudinal trial (n = 714) at five time points over a period of 6 months. Here we will describe the development and the content of this new intervention.

T1 - Mental number space in three dimensions JF - Neuroscience & biobehavioral reviews : official journal of the International Behavioral Neuroscience Society N2 - A large number of experimental findings from neuroscience and experimental psychology demonstrated interactions between spatial cognition and numerical cognition. In particular, many researchers posited a horizontal mental number line, where small numbers are thought of as being to the left of larger numbers. This review synthesizes work on the mental association between space and number, indicating the existence of multiple spatial mappings: recent research has found associations between number and vertical space, as well as associations between number and near/far space. We discuss number space in three dimensions with an eye on potential origins of the different number mappings, and how these number mappings fit in with our current knowledge of brain organization and brain-culture interactions. We derive novel predictions and show how this research fits into a general view of cognition as embodied, grounded and situated. (C) 2015 Elsevier Ltd. All rights reserved.

With this special setup, a two-dimensional fluid can be realized experimentally. The physics of the system involves a complex interplay of thermal convection and interface and gravitational forces. Methodologically, we characterize the system using two classical dynamical systems properties: Lyapunov exponents and entropies. Our experimental setup produces convection with two stable eddies by applying a temperature gradient in one spot that yields weakly turbulent mixing. From dynamical systems theory, one expects a relation of entropies, Lyapunov exponents, a prediction with little experimental support. We can confirm the corresponding statements experimentally, on different scales using different methods. On the small scale the motion and deformation of fluid filaments of equal size (color imaging velocimetry) are used to compute Lyapunov exponents. On the large scale, entropy is computed by tracking the left-right motion of the center fluid jet at the separatrix between the two convection rolls. We thus combine here dynamical systems methods with a concrete application of mixing in a nanoscale freestanding thin film.

With respect to the active transport of matter by voles, bioturbation may be considered as a very dynamic process among those shaping soil formation and biogeochemistry. The present study aimed at characterizing and quantifying the effects of bioturbation by voles on soil water relations and carbon and nitrogen stocks. Bioturbation effects were examined based on a field set up in a luvic arenosol comprising of eight 50 x 50 m enclosures with greatly different numbers of common vole (Microtus arvalis L., ca. 35-150 individuals ha(-1) mth(-1)). Eleven key soil variables were analyzed: bulk density, infiltration rate, saturated hydraulic conductivity, water holding capacity, contents of soil organic carbon (SOC) and total nitrogen (N), CO2 emission potential, C/N ratio, the stable isotopic signatures of C-13 and N-15, and pH. The highest vole densities were hypothesized to cause significant changes in some variables within 21 months. Results showed that land history had still a major influence, as eight key variables displayed an additional or sole influence of topography. However, the delta N-15 at depths of 10-20 and 20-30 cm decreased and increased with increasing vole numbers, respectively. Also the CO2 emission potential from soil collected at a depth of 15-30 cm decreased and the C/N ratio at 5-10 cm depth narrowed with increasing vole numbers. These variables indicated the first influence of voles on the respective mineralization processes in some soil layers. Tendencies of vole activity homogenizing SOC and N contents across layers were not significant. The results of the other seven key variables did not confirm significant effects of voles. Thus overall, we found mainly a first response of variables that are indicative for changes in biogeochemical dynamics but not yet of those representing changes in pools.
