  abstract  = {Planetary research is often user-based and requires considerable skill, time, and effort. Unfortunately, self-defined boundary conditions, definitions, and rules are often not documented or not easy to comprehend due to the complexity of research. This makes a comparison to other studies, or an extension of the already existing research, complicated. Comparisons are often distorted, because results rely on different, not well defined, or even unknown boundary conditions. The purpose of this research is to develop a standardized analysis method for planetary surfaces, which is adaptable to several research topics. The method provides a consistent quality of results. This also includes achieving reliable and comparable results and reducing the time and effort of conducting such studies. A standardized analysis method is provided by automated analysis tools that focus on statistical parameters. Specific key parameters and boundary conditions are defined for the tool application. The analysis relies on a database in which all key parameters are stored. These databases can be easily updated and adapted to various research questions. This increases the flexibility, reproducibility, and comparability of the research. However, the quality of the database and reliability of definitions directly influence the results. To ensure a high quality of results, the rules and definitions need to be well defined and based on previously conducted case studies. The tools then produce parameters, which are obtained by defined geostatistical techniques (measurements, calculations, classifications). The idea of an automated statistical analysis is tested to proof benefits but also potential problems of this method. In this study, I adapt automated tools for floor-fractured craters (FFCs) on Mars. These impact craters show a variety of surface features, occurring in different Martian environments, and having different fracturing origins. They provide a complex morphological and geological field of application. 433 FFCs are classified by the analysis tools due to their fracturing process. Spatial data, environmental context, and crater interior data are analyzed to distinguish between the processes involved in floor fracturing. Related geologic processes, such as glacial and fluvial activity, are too similar to be separately classified by the automated tools. Glacial and fluvial fracturing processes are merged together for the classification. The automated tools provide probability values for each origin model. To guarantee the quality and reliability of the results, classification tools need to achieve an origin probability above 50 \%. This analysis method shows that 15 \% of the FFCs are fractured by intrusive volcanism, 20 \% by tectonic activity, and 43 \% by water \& ice related processes. In total, 75 \% of the FFCs are classified to an origin type. This can be explained by a combination of origin models, superposition or erosion of key parameters, or an unknown fracturing model. Those features have to be manually analyzed in detail. Another possibility would be the improvement of key parameters and rules for the classification. This research shows that it is possible to conduct an automated statistical analysis of morphologic and geologic features based on analysis tools. Analysis tools provide additional information to the user and are therefore considered assistance systems.},

  abstract  = {The H.E.S.S. array is a third generation Imaging Atmospheric Cherenkov Telescope (IACT) array. It is located in the Khomas Highland in Namibia, and measures very high energy (VHE) gamma-rays. In Phase I, the array started data taking in 2004 with its four identical 13 m telescopes. Since then, H.E.S.S. has emerged as the most successful IACT experiment to date. Among the almost 150 sources of VHE gamma-ray radiation found so far, even the oldest detection, the Crab Nebula, keeps surprising the scientific community with unexplained phenomena such as the recently discovered very energetic flares of high energy gamma-ray radiation. During its most recent flare, which was detected by the Fermi satellite in March 2013, the Crab Nebula was simultaneously observed with the H.E.S.S. array for six nights. The results of the observations will be discussed in detail during the course of this work. During the nights of the flare, the new 24 m × 32 m H.E.S.S. II telescope was still being commissioned, but participated in the data taking for one night. To be able to reconstruct and analyze the data of the H.E.S.S. Phase II array, the algorithms and software used by the H.E.S.S. Phase I array had to be adapted. The most prominent advanced shower reconstruction technique developed by de Naurois and Rolland, the template-based model analysis, compares real shower images taken by the Cherenkov telescope cameras with shower templates obtained using a semi-analytical model. To find the best fitting image, and, therefore, the relevant parameters that describe the air shower best, a pixel-wise log-likelihood fit is done. The adaptation of this advanced shower reconstruction technique to the heterogeneous H.E.S.S. Phase II array for stereo events (i.e. air showers seen by at least two telescopes of any kind), its performance using MonteCarlo simulations as well as its application to real data will be described.},

  abstract  = {This work introduces concepts and corresponding tool support to enable a complementary approach in dealing with recovery. Programmers need to recover a development state, or a part thereof, when previously made changes reveal undesired implications. However, when the need arises suddenly and unexpectedly, recovery often involves expensive and tedious work. To avoid tedious work, literature recommends keeping away from unexpected recovery demands by following a structured and disciplined approach, which consists of the application of various best practices including working only on one thing at a time, performing small steps, as well as making proper use of versioning and testing tools. However, the attempt to avoid unexpected recovery is both time-consuming and error-prone. On the one hand, it requires disproportionate effort to minimize the risk of unexpected situations. On the other hand, applying recommended practices selectively, which saves time, can hardly avoid recovery. In addition, the constant need for foresight and self-control has unfavorable implications. It is exhaustive and impedes creative problem solving. This work proposes to make recovery fast and easy and introduces corresponding support called CoExist. Such dedicated support turns situations of unanticipated recovery from tedious experiences into pleasant ones. It makes recovery fast and easy to accomplish, even if explicit commits are unavailable or tests have been ignored for some time. When mistakes and unexpected insights are no longer associated with tedious corrective actions, programmers are encouraged to change source code as a means to reason about it, as opposed to making changes only after structuring and evaluating them mentally. This work further reports on an implementation of the proposed tool support in the Squeak/Smalltalk development environment. The development of the tools has been accompanied by regular performance and usability tests. In addition, this work investigates whether the proposed tools affect programmers' performance. In a controlled lab study, 22 participants improved the design of two different applications. Using a repeated measurement setup, the study examined the effect of providing CoExist on programming performance. The result of analyzing 88 hours of programming suggests that built-in recovery support as provided with CoExist positively has a positive effect on programming performance in explorative programming tasks.},

  abstract  = {Wood is used for many applications because of its excellent mechanical properties, relative abundance and as it is a renewable resource. However, its wider utilization as an engineering material is limited because it swells and shrinks upon moisture changes and is susceptible to degradation by microorganisms and/or insects. Chemical modifications of wood have been shown to improve dimensional stability, water repellence and/or durability, thus increasing potential service-life of wood materials. However current treatments are limited because it is difficult to introduce and fix such modifications deep inside the tissue and cell wall. Within the scope of this thesis, novel chemical modification methods of wood cell walls were developed to improve both dimensional stability and water repellence of wood material. These methods were partly inspired by the heartwood formation in living trees, a process, that for some species results in an insertion of hydrophobic chemical substances into the cell walls of already dead wood cells, In the first part of this thesis a chemistry to modify wood cell walls was used, which was inspired by the natural process of heartwood formation. Commercially available hydrophobic flavonoid molecules were effectively inserted in the cell walls of spruce, a softwood species with low natural durability, after a tosylation treatment to obtain "artificial heartwood". Flavonoid inserted cell walls show a reduced moisture absorption, resulting in better dimensional stability, water repellency and increased hardness. This approach was quite different compared to established modifications which mainly address hydroxyl groups of cell wall polymers with hydrophilic substances. In the second part of the work in-situ styrene polymerization inside the tosylated cell walls was studied. It is known that there is a weak adhesion between hydrophobic polymers and hydrophilic cell wall components. The hydrophobic styrene monomers were inserted into the tosylated wood cell walls for further polymerization to form polystyrene in the cell walls, which increased the dimensional stability of the bulk wood material and reduced water uptake of the cell walls considerably when compared to controls. In the third part of the work, grafting of another hydrophobic and also biodegradable polymer, poly(ɛ-caprolactone) in the wood cell walls by ring opening polymerization of ɛ-caprolactone was studied at mild temperatures. Results indicated that polycaprolactone attached into the cell walls, caused permanent swelling of the cell walls up to 5\%. Dimensional stability of the bulk wood material increased 40\% and water absorption reduced more than 35\%. A fully biodegradable and hydrophobized wood material was obtained with this method which reduces disposal problem of the modified wood materials and has improved properties to extend the material's service-life. Starting from a bio-inspired approach which showed great promise as an alternative to standard cell wall modifications we showed the possibility of inserting hydrophobic molecules in the cell walls and supported this fact with in-situ styrene and ɛ-caprolactone polymerization into the cell walls. It was shown in this thesis that despite the extensive knowledge and long history of using wood as a material there is still room for novel chemical modifications which could have a high impact on improving wood properties.},

  abstract  = {In this thesis we consider diverse aspects of existence and correctness of asymptotic solutions to elliptic differential and pseudodifferential equations. We begin our studies with the case of a general elliptic boundary value problem in partial derivatives. A small parameter enters the coefficients of the main equation as well as into the boundary conditions. Such equations have already been investigated satisfactory, but there still exist certain theoretical deficiencies. Our aim is to present the general theory of elliptic problems with a small parameter. For this purpose we examine in detail the case of a bounded domain with a smooth boundary. First of all, we construct formal solutions as power series in the small parameter. Then we examine their asymptotic properties. It suffices to carry out sharp two-sided \emph{a priori} estimates for the operators of boundary value problems which are uniform in the small parameter. Such estimates failed to hold in functional spaces used in classical elliptic theory. To circumvent this limitation we exploit norms depending on the small parameter for the functions defined on a bounded domain. Similar norms are widely used in literature, but their properties have not been investigated extensively. Our theoretical investigation shows that the usual elliptic technique can be correctly carried out in these norms. The obtained results also allow one to extend the norms to compact manifolds with boundaries. We complete our investigation by formulating algebraic conditions on the operators and showing their equivalence to the existence of a priori estimates. In the second step, we extend the concept of ellipticity with a small parameter to more general classes of operators. Firstly, we want to compare the difference in asymptotic patterns between the obtained series and expansions for similar differential problems. Therefore we investigate the heat equation in a bounded domain with a small parameter near the time derivative. In this case the characteristics touch the boundary at a finite number of points. It is known that the solutions are not regular in a neighbourhood of such points in advance. We suppose moreover that the boundary at such points can be non-smooth but have cuspidal singularities. We find a formal asymptotic expansion and show that when a set of parameters comes through a threshold value, the expansions fail to be asymptotic. The last part of the work is devoted to general concept of ellipticity with a small parameter. Several theoretical extensions to pseudodifferential operators have already been suggested in previous studies. As a new contribution we involve the analysis on manifolds with edge singularities which allows us to consider wider classes of perturbed elliptic operators. We examine that introduced classes possess a priori estimates of elliptic type. As a further application we demonstrate how developed tools can be used to reduce singularly perturbed problems to regular ones.},

  abstract  = {The seismic structure (Vp, Vp/Vs, and Qp anomalies) contributes to the physical properties and the lithology of rocks and possible fluid distribution in the region. The Vp model images the geometry of the Tarutung and the Sarulla basins. Both basins have a depth of around 2.0 km. High Vp/Vs and high attenuation (low Qp) anomalies are observed along the Sarulla graben associated with a weak zone caused by volcanic activities along the graben. Low Vp/Vs and low conductivity anomalies are found in the west of the Tarutung basin. This anomaly is interpreted as dry, compact, and rigid granitic rock in the region as also found by geological observations. Low Vp, high Vp/Vs and low Qp anomalies are found at the east of the Tarutung basin which appear to be associated with the three big geothermal manifestations in Sipoholon, Hutabarat, and Panabungan area. These anomalies are connected with high Vp/Vs and low Qp anomalies below the Tarutung basin at depth of around 3 - 10 km. This suggests that these geothermal manifestations are fed by the same source of the hot fluid below the Tarutung basin. The hot fluids from below the Tarutung basin propagate to the more dilatational and more permeable zone in the northeast. Granite found in the west of the Tarutung basin could also be abundant underneath the basin at a certain depth so that it prevents the hot fluid to be transported directly to the Tarutung basin. High seismic attenuation and low Vp/Vs anomalies are found in the southwest of the Tarutung basin below the Martimbang volcano. These anomalies are associated with hot rock below the volcano without or with less amount of partial melting. There is no indication that the volcano controls the geothermal system around the Tarutung basin. The geothermal resources around the Tarutung basin is a fault-controlled system as a result of deep circulation of fluids. Outside of the basin, the seismicity delineation and the focal mechanism correlate with the shape and the characteristics of the strike-slip Sumatran fault. Within the Tarutung basin, the seismicity is distributed more broadly which coincides with the margin of the basin. An extensional duplex system in the Tarutung basin is derived from the seismicity and focal mechanism analysis which is also consistent with the geological observations. The vertical distribution of the seismicity suggests the presence of a negative flower structure within the Tarutung basin.},

  abstract  = {Metabolic systems tend to exhibit steady states that can be measured in terms of their concentrations and fluxes. These measurements can be regarded as a phenotypic representation of all the complex interactions and regulatory mechanisms taking place in the underlying metabolic network. Such interactions determine the system's response to external perturbations and are responsible, for example, for its asymptotic stability or for oscillatory trajectories around the steady state. However, determining these perturbation responses in the absence of fully specified kinetic models remains an important challenge of computational systems biology. Structural kinetic modeling (SKM) is a framework to analyse whether a metabolic steady state remains stable under perturbation, without requiring detailed knowledge about individual rate equations. It provides a parameterised representation of the system's Jacobian matrix in which the model parameters encode information about the enzyme-metabolite interactions. Stability criteria can be derived by generating a large number of structural kinetic models (SK-models) with randomly sampled parameter sets and evaluating the resulting Jacobian matrices. The parameter space can be analysed statistically in order to detect network positions that contribute significantly to the perturbation response. Because the sampled parameters are equivalent to the elasticities used in metabolic control analysis (MCA), the results are easy to interpret biologically. In this project, the SKM framework was extended by several novel methodological improvements. These improvements were evaluated in a simulation study using a set of small example pathways with simple Michaelis Menten rate laws. Afterwards, a detailed analysis of the dynamic properties of the neuronal TCA cycle was performed in order to demonstrate how the new insights obtained in this work could be used for the study of complex metabolic systems. The first improvement was achieved by examining the biological feasibility of the elasticity combinations created during Monte Carlo sampling. Using a set of small example systems, the findings showed that the majority of sampled SK-models would yield negative kinetic parameters if they were translated back into kinetic models. To overcome this problem, a simple criterion was formulated that mitigates such infeasible models and the application of this criterion changed the conclusions of the SKM experiment. The second improvement of this work was the application of supervised machine-learning approaches in order to analyse SKM experiments. So far, SKM experiments have focused on the detection of individual enzymes to identify single reactions important for maintaining the stability or oscillatory trajectories. In this work, this approach was extended by demonstrating how SKM enables the detection of ensembles of enzymes or metabolites that act together in an orchestrated manner to coordinate the pathways response to perturbations. In doing so, stable and unstable states served as class labels, and classifiers were trained to detect elasticity regions associated with stability and instability. Classification was performed using decision trees and relevance vector machines (RVMs). The decision trees produced good classification accuracy in terms of model bias and generalizability. RVMs outperformed decision trees when applied to small models, but encountered severe problems when applied to larger systems because of their high runtime requirements. The decision tree rulesets were analysed statistically and individually in order to explore the role of individual enzymes or metabolites in controlling the system's trajectories around steady states. The third improvement of this work was the establishment of a relationship between the SKM framework and the related field of MCA. In particular, it was shown how the sampled elasticities could be converted to flux control coefficients, which were then investigated for their predictive information content in classifier training. After evaluation on the small example pathways, the methodology was used to study two steady states of the neuronal TCA cycle with respect to their intrinsic mechanisms responsible for stability or instability. The findings showed that several elasticities were jointly coordinated to control stability and that the main source for potential instabilities were mutations in the enzyme alpha-ketoglutarate dehydrogenase.},

  abstract  = {The tropical warm pool waters surrounding Indonesia are one of the equatorial heat and moisture sources that are considered as a driving force of the global climate system. The climate in Indonesia is dominated by the equatorial monsoon system, and has been linked to El Ni{\~n}o-Southern Oscillation (ENSO) events, which often result in severe droughts or floods over Indonesia with profound societal and economic impacts on the populations living in the world's fourth most populated country. The latest IPCC report states that ENSO will remain the dominant mode in the tropical Pacific with global effects in the 21st century and ENSO-related precipitation extremes will intensify. However, no common agreement exists among climate simulation models for projected change in ENSO and the Australian-Indonesian Monsoon. Exploring high-resolution palaeoclimate archives, like tree rings or varved lake sediments, provide insights into the natural climate variability of the past, and thus helps improving and validating simulations of future climate changes. Centennial tree-ring stable isotope records | Within this doctoral thesis the main goal was to explore the potential of tropical tree rings to record climate signals and to use them as palaeoclimate proxies. In detail, stable carbon (δ13C) and oxygen (δ18O) isotopes were extracted from teak trees in order to establish the first well-replicated centennial (AD 1900-2007) stable isotope records for Java, Indonesia. Furthermore, different climatic variables were tested whether they show significant correlation with tree-ring proxies (ring-width, δ13C, δ18O). Moreover, highly resolved intra-annual oxygen isotope data were established to assess the transfer of the seasonal precipitation signal into the tree rings. Finally, the established oxygen isotope record was used to reveal possible correlations with ENSO events. Methodological achievements | A second goal of this thesis was to assess the applicability of novel techniques which facilitate and optimize high-resolution and high-throughput stable isotope analysis of tree rings. Two different UV-laser-based microscopic dissection systems were evaluated as a novel sampling tool for high-resolution stable isotope analysis. Furthermore, an improved procedure of tree-ring dissection from thin cellulose laths for stable isotope analysis was designed. The most important findings of this thesis are: I) The herein presented novel sampling techniques improve stable isotope analyses for tree-ring studies in terms of precision, efficiency and quality. The UV-laser-based microdissection serve as a valuable tool for sampling plant tissue at ultrahigh-resolution and for unprecedented precision. II) A guideline for a modified method of cellulose extraction from wholewood cross-sections and subsequent tree-ring dissection was established. The novel technique optimizes the stable isotope analysis process in two ways: faster and high-throughput cellulose extraction and precise tree-ring separation at annual to high-resolution scale. III) The centennial tree-ring stable isotope records reveal significant correlation with regional precipitation. High-resolution stable oxygen values, furthermore, allow distinguishing between dry and rainy season rainfall. IV) The δ18O record reveals significant correlation with different ENSO flavors and demonstrates the importance of considering ENSO flavors when interpreting palaeoclimatic data in the tropics. The findings of my dissertation show that seasonally resolved δ18O records from Indonesian teak trees are a valuable proxy for multi-centennial reconstructions of regional precipitation variability (monsoon signals) and large-scale ocean-atmosphere phenomena (ENSO) for the Indo-Pacific region. Furthermore, the novel methodological achievements offer many unexplored avenues for multidisciplinary research in high-resolution palaeoclimatology.},

  abstract  = {The Adana Basin of southern Turkey, situated at the SE margin of the Central Anatolian Plateau is ideally located to record Neogene topographic and tectonic changes in the easternmost Mediterranean realm. Using industry seismic reflection data we correlate 34 seismic profiles with corresponding exposed units in the Adana Basin. The time-depth conversion of the interpreted seismic profiles allows us to reconstruct the subsidence curve of the Adana Basin and to outline the occurrence of a major increase in both subsidence and sedimentation rates at 5.45 - 5.33 Ma, leading to the deposition of almost 1500 km3 of conglomerates and marls. Our provenance analysis of the conglomerates reveals that most of the sediment is derived from and north of the SE margin of the Central Anatolian Plateau. A comparison of these results with the composition of recent conglomerates and the present drainage basins indicates major changes between late Messinian and present-day source areas. We suggest that these changes in source areas result of uplift and ensuing erosion of the SE margin of the plateau. This hypothesis is supported by the comparison of the Adana Basin subsidence curve with the subsidence curve of the Mut Basin, a mainly Neogene basin located on top of the Central Anatolian Plateau southern margin, showing that the Adana Basin subsidence event is coeval with an uplift episode of the plateau southern margin. The collection of several fault measurements in the Adana region show different deformation styles for the NW and SE margins of the Adana Basin. The weakly seismic NW portion of the basin is characterized by extensional and transtensional structures cutting Neogene deposits, likely accomodating the differential uplift occurring between the basin and the SE margin of the plateau. We interpret the tectonic evolution of the southern flank of the Central Anatolian Plateau and the coeval subsidence and sedimentation in the Adana Basin to be related to deep lithospheric processes, particularly lithospheric delamination and slab break-off.},

Die Stabilisierung der Bev{\"o}lkerung stand sodann unter dem Zeichen der sozialistischen Gesellschafts- und Wirtschaftsordnung, die die Lebensweise und Raumwahrnehmung der neuen Einwohner nachhaltig pr{\"a}gte. Die Grenz{\"o}ffnung von 1989, die politische Transformation sowie die Integration der Tschechischen Republik in die Europ{\"a}ische Union brachten neue demographische und sozio{\"o}konomische Entwicklungen mit sich. Sie schufen aber auch die Bedingungen daf{\"u}r, sich neu und offen auch mit der spezifischen Geschichte des ehemaligen Sudetenlandes sowie mit dem Zustand der gegenw{\"a}rtigen Gesellschaft in diesem Gebiet auseinanderzusetzen. Im Rahmen der vorliegenden Arbeit wird anhand zweier Beispielregionen untersucht, welche Raumvorstellungen und Raumbindungen bei der heute in den ehemaligen sudetendeutschen Gebieten ans{\"a}ssigen Bev{\"o}lkerung vorhanden sind und welche Einfl{\"u}sse die unterschiedlichen raumstrukturellen Bedingungen darauf aus{\"u}ben.

  abstract  = {The work elaborates on the question if coaches in non-professional soccer can influence referee decisions. Modeled from a principal-agent perspective, the managing referee boards can be seen as the principal. They aim at facilitating a fair competition which is in accordance with the existing rules and regulations. In doing so, the referees are assigned as impartial agents on the pitch. The coaches take over a non-legitimate principal-like role trying to influence the referees even though they do not have the formal right to do so. Separate questionnaires were set up for referees and coaches. The coach questionnaire aimed at identifying the extent and the forms of influencing attempts by coaches. The referee questionnaire tried to elaborate on the questions if referees take notice of possible influencing attempts and how they react accordingly. The results were put into relation with official match data in order to identify significant influences on personal sanctions (yellow cards, second yellow cards, red cards) and the match result. It is found that there is a slight effect on the referee's decisions. However, this effect is rather disadvantageous for the influencing coach and there is no evidence for an impact on the match result itself.},

  abstract  = {In the field of disk-based parallel database management systems exists a great variety of solutions based on a shared-storage or a shared-nothing architecture. In contrast, main memory-based parallel database management systems are dominated solely by the shared-nothing approach as it preserves the in-memory performance advantage by processing data locally on each server. We argue that this unilateral development is going to cease due to the combination of the following three trends: a) Nowadays network technology features remote direct memory access (RDMA) and narrows the performance gap between accessing main memory inside a server and of a remote server to and even below a single order of magnitude. b) Modern storage systems scale gracefully, are elastic, and provide high-availability. c) A modern storage system such as Stanford's RAMCloud even keeps all data resident in main memory. Exploiting these characteristics in the context of a main-memory parallel database management system is desirable. The advent of RDMA-enabled network technology makes the creation of a parallel main memory DBMS based on a shared-storage approach feasible. This thesis describes building a columnar database on shared main memory-based storage. The thesis discusses the resulting architecture (Part I), the implications on query processing (Part II), and presents an evaluation of the resulting solution in terms of performance, high-availability, and elasticity (Part III). In our architecture, we use Stanford's RAMCloud as shared-storage, and the self-designed and developed in-memory AnalyticsDB as relational query processor on top. AnalyticsDB encapsulates data access and operator execution via an interface which allows seamless switching between local and remote main memory, while RAMCloud provides not only storage capacity, but also processing power. Combining both aspects allows pushing-down the execution of database operators into the storage system. We describe how the columnar data processed by AnalyticsDB is mapped to RAMCloud's key-value data model and how the performance advantages of columnar data storage can be preserved. The combination of fast network technology and the possibility to execute database operators in the storage system opens the discussion for site selection. We construct a system model that allows the estimation of operator execution costs in terms of network transfer, data processed in memory, and wall time. This can be used for database operators that work on one relation at a time - such as a scan or materialize operation - to discuss the site selection problem (data pull vs. operator push). Since a database query translates to the execution of several database operators, it is possible that the optimal site selection varies per operator. For the execution of a database operator that works on two (or more) relations at a time, such as a join, the system model is enriched by additional factors such as the chosen algorithm (e.g. Grace- vs. Distributed Block Nested Loop Join vs. Cyclo-Join), the data partitioning of the respective relations, and their overlapping as well as the allowed resource allocation. We present an evaluation on a cluster with 60 nodes where all nodes are connected via RDMA-enabled network equipment. We show that query processing performance is about 2.4x slower if everything is done via the data pull operator execution strategy (i.e. RAMCloud is being used only for data access) and about 27\% slower if operator execution is also supported inside RAMCloud (in comparison to operating only on main memory inside a server without any network communication at all). The fast-crash recovery feature of RAMCloud can be leveraged to provide high-availability, e.g. a server crash during query execution only delays the query response for about one second. Our solution is elastic in a way that it can adapt to changing workloads a) within seconds, b) without interruption of the ongoing query processing, and c) without manual intervention.},

  abstract  = {Bacteria respond to changing environmental conditions by switching the global pattern of expressed genes. In response to specific environmental stresses the cell activates several stress-specific molecules such as sigma factors. They reversibly bind the RNA polymerase to form the so-called holoenzyme and direct it towards the appropriate stress response genes. In exponentially growing E. coli cells, the majority of the transcriptional activity is carried out by the housekeeping sigma factor, while stress responses are often under the control of alternative sigma factors. Different sigma factors compete for binding to a limited pool of RNA polymerase (RNAP) core enzymes, providing a mechanism for cross talk between genes or gene classes via the sharing of expression machinery. To quantitatively analyze the contribution of sigma factor competition to global changes in gene expression, we develop a thermodynamic model that describes binding between sigma factors and core RNAP at equilibrium, transcription, non-specific binding to DNA and the modulation of the availability of the molecular components. Association of housekeeping sigma factor to RNAP is generally favored by its abundance and higher binding affinity to the core. In order to promote transcription by alternative sigma subunits, the bacterial cell modulates the transcriptional efficiency in a reversible manner through several strategies such as anti-sigma factors, 6S RNA and generally any kind of transcriptional regulators (e.g. activators or inhibitors). By shifting the outcome of sigma factor competition for the core, these modulators bias the transcriptional program of the cell. The model is validated by comparison with in vitro competition experiments, with which excellent agreement is found. We observe that transcription is affected via the modulation of the concentrations of the different types of holoenzymes, so saturated promoters are only weakly affected by sigma factor competition. However, in case of overlapping promoters or promoters recognized by two types of sigma factors, we find that even saturated promoters are strongly affected. Active transcription effectively lowers the affinity between the sigma factor driving it and the core RNAP, resulting in complex cross talk effects and raising the question of how their in vitro measure is relevant in the cell. We also estimate that sigma factor competition is not strongly affected by non-specific binding of core RNAPs, sigma factors, and holoenzymes to DNA. Finally, we analyze the role of increased core RNAP availability upon the shut-down of ribosomal RNA transcription during stringent response. We find that passive up-regulation of alternative sigma-dependent transcription is not only possible, but also displays hypersensitivity based on the sigma factor competition. Our theoretical analysis thus provides support for a significant role of passive control during that global switch of the gene expression program and gives new insights into RNAP partitioning in the cell.},

  abstract  = {In the presented thesis, the most advanced photon reconstruction technique of ground-based γ-ray astronomy is adapted to the H.E.S.S. 28 m telescope. The method is based on a semi-analytical model of electromagnetic particle showers in the atmosphere. The properties of cosmic γ-rays are reconstructed by comparing the camera image of the telescope with the Cherenkov emission that is expected from the shower model. To suppress the dominant background from charged cosmic rays, events are selected based on several criteria. The performance of the analysis is evaluated with simulated events. The method is then applied to two sources that are known to emit γ-rays. The first of these is the Crab Nebula, the standard candle of ground-based γ-ray astronomy. The results of this source confirm the expected performance of the reconstruction method, where the much lower energy threshold compared to H.E.S.S. I is of particular importance. A second analysis is performed on the region around the Galactic Centre. The analysis results emphasise the capabilities of the new telescope to measure γ-rays in an energy range that is interesting for both theoretical and experimental astrophysics. The presented analysis features the lowest energy threshold that has ever been reached in ground-based γ-ray astronomy, opening a new window to the precise measurement of the physical properties of time-variable sources at energies of several tens of GeV.},

  abstract  = {Nowadays, software systems are getting more and more complex. To tackle this challenge most diverse techniques, such as design patterns, service oriented architectures (SOA), software development processes, and model-driven engineering (MDE), are used to improve productivity, while time to market and quality of the products stay stable. Multiple of these techniques are used in parallel to profit from their benefits. While the use of sophisticated software development processes is standard, today, MDE is just adopted in practice. However, research has shown that the application of MDE is not always successful. It is not fully understood when advantages of MDE can be used and to what degree MDE can also be disadvantageous for productivity. Further, when combining different techniques that aim to affect the same factor (e.g. productivity) the question arises whether these techniques really complement each other or, in contrast, compensate their effects. Due to that, there is the concrete question how MDE and other techniques, such as software development process, are interrelated. Both aspects (advantages and disadvantages for productivity as well as the interrelation to other techniques) need to be understood to identify risks relating to the productivity impact of MDE. Before studying MDE's impact on productivity, it is necessary to investigate the range of validity that can be reached for the results. This includes two questions. First, there is the question whether MDE's impact on productivity is similar for all approaches of adopting MDE in practice. Second, there is the question whether MDE's impact on productivity for an approach of using MDE in practice remains stable over time. The answers for both questions are crucial for handling risks of MDE, but also for the design of future studies on MDE success. This thesis addresses these questions with the goal to support adoption of MDE in future. To enable a differentiated discussion about MDE, the term MDE setting'' is introduced. MDE setting refers to the applied technical setting, i.e. the employed manual and automated activities, artifacts, languages, and tools. An MDE setting's possible impact on productivity is studied with a focus on changeability and the interrelation to software development processes. This is done by introducing a taxonomy of changeability concerns that might be affected by an MDE setting. Further, three MDE traits are identified and it is studied for which manifestations of these MDE traits software development processes are impacted. To enable the assessment and evaluation of an MDE setting's impacts, the Software Manufacture Model language is introduced. This is a process modeling language that allows to reason about how relations between (modeling) artifacts (e.g. models or code files) change during application of manual or automated development activities. On that basis, risk analysis techniques are provided. These techniques allow identifying changeability risks and assessing the manifestations of the MDE traits (and with it an MDE setting's impact on software development processes). To address the range of validity, MDE settings from practice and their evolution histories were capture in context of this thesis. First, this data is used to show that MDE settings cover the whole spectrum concerning their impact on changeability or interrelation to software development processes. Neither it is seldom that MDE settings are neutral for processes nor is it seldom that MDE settings have impact on processes. Similarly, the impact on changeability differs relevantly. Second, a taxonomy of evolution of MDE settings is introduced. In that context it is discussed to what extent different types of changes on an MDE setting can influence this MDE setting's impact on changeability and the interrelation to processes. The category of structural evolution, which can change these characteristics of an MDE setting, is identified. The captured MDE settings from practice are used to show that structural evolution exists and is common. In addition, some examples of structural evolution steps are collected that actually led to a change in the characteristics of the respective MDE settings. Two implications are: First, the assessed diversity of MDE settings evaluates the need for the analysis techniques that shall be presented in this thesis. Second, evolution is one explanation for the diversity of MDE settings in practice. To summarize, this thesis studies the nature and evolution of MDE settings in practice. As a result support for the adoption of MDE settings is provided in form of techniques for the identification of risks relating to productivity impacts.},

  abstract  = {In processing and data storage mainly ferromagnetic (FM) materials are being used. Approaching physical limits, new concepts have to be found for faster, smaller switches, for higher data densities and more energy efficiency. Some of the discussed new concepts involve the material classes of correlated oxides and materials with antiferromagnetic coupling. Their applicability depends critically on their switching behavior, i.e., how fast and how energy efficient material properties can be manipulated. This thesis presents investigations of ultrafast non-equilibrium phase transitions on such new materials. In transition metal oxides (TMOs) the coupling of different degrees of freedom and resulting low energy excitation spectrum often result in spectacular changes of macroscopic properties (colossal magneto resistance, superconductivity, metal-to-insulator transitions) often accompanied by nanoscale order of spins, charges, orbital occupation and by lattice distortions, which make these material attractive. Magnetite served as a prototype for functional TMOs showing a metal-to-insulator-transition (MIT) at T = 123 K. By probing the charge and orbital order as well as the structure after an optical excitation we found that the electronic order and the structural distortion, characteristics of the insulating phase in thermal equilibrium, are destroyed within the experimental resolution of 300 fs. The MIT itself occurs on a 1.5 ps timescale. It shows that MITs in functional materials are several thousand times faster than switching processes in semiconductors. Recently ferrimagnetic and antiferromagnetic (AFM) materials have become interesting. It was shown in ferrimagnetic GdFeCo, that the transfer of angular momentum between two opposed FM subsystems with different time constants leads to a switching of the magnetization after laser pulse excitation. In addition it was theoretically predicted that demagnetization dynamics in AFM should occur faster than in FM materials as no net angular momentum has to be transferred out of the spin system. We investigated two different AFM materials in order to learn more about their ultrafast dynamics. In Ho, a metallic AFM below T ≈ 130 K, we found that the AFM Ho can not only be faster but also ten times more energy efficiently destroyed as order in FM comparable metals. In EuTe, an AFM semiconductor below T ≈ 10 K, we compared the loss of magnetization and laser-induced structural distortion in one and the same experiment. Our experiment shows that they are effectively disentangled. An exception is an ultrafast release of lattice dynamics, which we assign to the release of magnetostriction. The results presented here were obtained with time-resolved resonant soft x-ray diffraction at the Femtoslicing source of the Helmholtz-Zentrum Berlin and at the free-electron laser in Stanford (LCLS). In addition the development and setup of a new UHV-diffractometer for these experiments will be reported.},

  abstract  = {Type 2 diabetes (T2D) is a health problem throughout the world. In 2010, there were nearly 230 million individuals with diabetes worldwide and it is estimated that in the economically advanced countries the cases will increase about 50\% in the next twenty years. Insulin resistance is one of major features in T2D, which is also a risk factor for metabolic and cardiovascular complications. Epidemiological and animal studies have shown that the consumption of vegetables and fruits can delay or prevent the development of the disease, although the underlying mechanisms of these effects are still unclear. Brassica species such as broccoli (Brassica oleracea var. italica) and nasturtium (Tropaeolum majus) possess high content of bioactive phytochemicals, e.g. nitrogen sulfur compounds (glucosinolates and isothiocyanates) and polyphenols largely associated with the prevention of cancer. Isothiocyanates (ITCs) display their anti-carcinogenic potential by inducing detoxicating phase II enzymes and increasing glutathione (GSH) levels in tissues. In T2D diabetes an increase in gluconeogenesis and triglyceride synthesis, and a reduction in fatty acid oxidation accompanied by the presence of reactive oxygen species (ROS) are observed; altogether is the result of an inappropriate response to insulin. Forkhead box O (FOXO) transcription factors play a crucial role in the regulation of insulin effects on gene expression and metabolism, and alterations in FOXO function could contribute to metabolic disorders in diabetes. In this study using stably transfected human osteosarcoma cells (U-2 OS) with constitutive expression of FOXO1 protein labeled with GFP (green fluorescent protein) and human hepatoma cells HepG2 cell cultures, the ability of benzylisothiocyanate (BITC) deriving from benzylglucosinolate, extracted from nasturtium to modulate, i) the insulin-signaling pathway, ii) the intracellular localization of FOXO1 and iii) the expression of proteins involved in glucose metabolism, ROS detoxification, cell cycle arrest and DNA repair was evaluated. BITC promoted oxidative stress and in response to that induced FOXO1 translocation from cytoplasm into the nucleus antagonizing the insulin effect. BITC stimulus was able to down-regulate gluconeogenic enzymes, which can be considered as an anti-diabetic effect; to promote antioxidant resistance expressed by the up-regulation in manganese superoxide dismutase (MnSOD) and detoxification enzymes; to modulate autophagy by induction of BECLIN1 and down-regulation of the mammalian target of rapamycin complex 1 (mTORC1) pathway; and to promote cell cycle arrest and DNA damage repair by up-regulation of the cyclin-dependent kinase inhibitor (p21CIP) and Growth Arrest / DNA Damage Repair (GADD45). Except for the nuclear factor (erythroid derived)-like2 (NRF2) and its influence in the detoxification enzymes gene expression, all the observed effects were independent from FOXO1, protein kinase B (AKT/PKB) and NAD-dependent deacetylase sirtuin-1 (SIRT1). The current study provides evidence that besides of the anticarcinogenic potential, isothiocyanates might have a role in T2D prevention. BITC stimulus mimics the fasting state, in which insulin signaling is not triggered and FOXO proteins remain in the nucleus modulating gene expression of their target genes, with the advantage of a down-regulation of gluconeogenesis instead of its increase. These effects suggest that BITC might be considered as a promising substance in the prevention or treatment of T2D, therefore the factors behind of its modulatory effects need further investigation.},

  abstract  = {Software maintenance encompasses any changes made to a software system after its initial deployment and is thereby one of the key phases in the typical software-engineering lifecycle. In software maintenance, we primarily need to understand structural and behavioral aspects, which are difficult to obtain, e.g., by code reading. Software analysis is therefore a vital tool for maintaining these systems: It provides - the preferably automated - means to extract and evaluate information from their artifacts such as software structure, runtime behavior, and related processes. However, such analysis typically results in massive raw data, so that even experienced engineers face difficulties directly examining, assessing, and understanding these data. Among other things, they require tools with which to explore the data if no clear question can be formulated beforehand. For this, software analysis and visualization provide its users with powerful interactive means. These enable the automation of tasks and, particularly, the acquisition of valuable and actionable insights into the raw data. For instance, one means for exploring runtime behavior is trace visualization. This thesis aims at extending and improving the tool set for visual software analysis by concentrating on several open challenges in the fields of dynamic and static analysis of software systems. This work develops a series of concepts and tools for the exploratory visualization of the respective data to support users in finding and retrieving information on the system artifacts concerned. This is a difficult task, due to the lack of appropriate visualization metaphors; in particular, the visualization of complex runtime behavior poses various questions and challenges of both a technical and conceptual nature. This work focuses on a set of visualization techniques for visually representing control-flow related aspects of software traces from shared-memory software systems: A trace-visualization concept based on icicle plots aids in understanding both single-threaded as well as multi-threaded runtime behavior on the function level. The concept's extensibility further allows the visualization and analysis of specific aspects of multi-threading such as synchronization, the correlation of such traces with data from static software analysis, and a comparison between traces. Moreover, complementary techniques for simultaneously analyzing system structures and the evolution of related attributes are proposed. These aim at facilitating long-term planning of software architecture and supporting management decisions in software projects by extensions to the circular-bundle-view technique: An extension to 3-dimensional space allows for the use of additional variables simultaneously; interaction techniques allow for the modification of structures in a visual manner. The concepts and techniques presented here are generic and, as such, can be applied beyond software analysis for the visualization of similarly structured data. The techniques' practicability is demonstrated by several qualitative studies using subject data from industry-scale software systems. The studies provide initial evidence that the techniques' application yields useful insights into the subject data and its interrelationships in several scenarios.},

  abstract  = {Diese Arbeit untersucht, was passiert, wenn in Non-Profit-Organisation (NPO) der Anspruch des B{\"u}rgerschaftlichen Engagements auf Praktiken des Freiwilligenmanagements trifft. Ausgangspunkt dieser Fragestellung ist eine doppelte Diagnose: Zum einen setzen NPOs aufgrund mehrerer Faktoren - u.a. Ressourcenknappheit, Wettbewerb und Nachahmungseffekten - vermehrt auf Freiwilligenmanagement. Mit dieser von der BWL inspirierten, aber f{\"u}r NPO entwickelten Personalf{\"u}hrungsmethode wollen sie mehr und bessere Freiwillige gewinnen und deren Einsatz effizienter strukturieren. Zum anderen haben sich gleichzeitig viele NPO dem Ziel des b{\"u}rgerschaftlichen Engagements verschrieben. Damit reagieren sie auf den aus Politik und Wissenschaft zu vernehmenden Anspruch, die Zivilgesellschaft m{\"o}ge die knappen Kassen der {\"o}ffentlichen Hand kompensieren und das wachsende Partizipationsbed{\"u}rfnis weiter Teile der Bev{\"o}lkerung durch eine neue Kultur der Teilhabe der B{\"u}rgerinnen und B{\"u}rger befriedigen. Bei n{\"a}herer Betrachtung zeigt sich jedoch: W{\"a}hrend Freiwilligenmanagement einer {\"o}konomischen Handlungslogik folgt, ist b{\"u}rgerschaftliches Engagement Ausdruck einer Handlungslogik der Zivilgesellschaft. Beide sind unter gegenw{\"a}rtigen Bedingungen weder theoretisch noch praktisch miteinander vereinbar. Um beide Entwicklungen miteinander zu vers{\"o}hnen, muss Freiwilligenmanagement unter dem Banner des B{\"u}rgerschaftlichen neu gedacht werden. Dieses Argument unterf{\"u}ttert die Arbeit sowohl theoretisch und empirisch. Der Theorieteil gliedert sich in drei Teile. Zun{\"a}chst wird der Begriff der NPO n{\"a}her eingegrenzt. Dazu wird die bestehende Literatur zum Dritten Sektor und Non-Profit-Organisationen zu einem operationalisierbaren Begriff von NPO kondensiert. Daran anschließend werden aktuelle Trends im Feld der NPO identifiziert, die zeigen, dass NPO tats{\"a}chlich oft von widerstreitenden Handlungslogiken gekennzeichnet sind, darunter eine {\"o}konomische und eine b{\"u}rgerschaftliche. Die beiden folgenden Kapitel untersuchen dann jeweils eine der beiden Logiken. Zun{\"a}chst wird das Leitbild des b{\"u}rgerschaftlichen Engagements als Ausdruck einer zivilgesellschaftlichen Handlungslogik n{\"a}her definiert. Dabei zeigt sich, dass dieser Begriff oft sehr unscharf verwendet wird. Daher greift die Arbeit auf die politiktheoretische Diskussion um Zivil- und B{\"u}rgergesellschaft auf und schmiedet daraus eine qualifizierte Definition von b{\"u}rgerschaftlichem Engagement, die sich maßgeblich am Ideal von gesellschaftlich-politischer Partizipation und b{\"u}rgerschaftlicher Kompetenz orientiert. Dem wird im dritten und letzten Kapitel des Theorieteils die {\"o}konomische Handlungslogik in Form der Theorie des Freiwilligenmanagements gegen{\"u}bergestellt. Bei der Darstellung zeigt sich schnell, dass dessen Grundprinzipien - anders als oft vorgebracht - mit den qualifizierten Idealen von Partizipation und Konkurrenz im Konflikt stehen. In der empirischen Analyse wird dann in den 8 Interviews den Widerspr{\"u}chen zwischen b{\"u}rgerschaftlichem Engagement und Freiwilligenmanagement in der Praxis nachgegangen. Die Ergebnisse dieser Untersuchung lassen sich in 5 Punkten zusammenfassen: 1. Freiwilligenmanagement orientiert sich erstens im wesentlichen an einer Zahl: Dem Zugewinn oder Verlust von freiwilliger Arbeit. 2. Freiwilligenmanagement installiert ein umfassendes System der Selektion von „passenden" Freiwilligen. 3. Positiv hervorzuheben ist die institutionalisierte Ansprechbarkeit, die im Rahmen von Freiwilligenmanagement in NPO Einzug erh{\"a}lt. 4. Freiwilligenmanagement ist eng mit dem Anspruch verbunden, die Arbeit der Freiwilligen zu kontrollieren. Der Eigensinn des Engagements, die Notwendigkeit von Spielr{\"a}umen, die M{\"o}glichkeit des Ausprobierens oder der Anspruch der Freiwilligen, an Entscheidungen zu partizipieren bzw. gar selbstorganisiert und -verantwortlich zu handeln, r{\"u}ckt dabei in den Hintergrund. 5. In den Interviews wird eine starke {\"O}konomisierung des Engagements sichtbar. Freiwillige werden als Ressource betrachtet, ihr Engagement als „Zeitspende" statistisch erfasst, ihre (Dienst-)Leistung monet{\"a}r bewertet. Im Zuge dessen erh{\"a}lt auch der Managerialism verst{\"a}rkt Einfluss auf die Arbeit in NPO und begr{\"u}ndet ein stark hierarchisches Verh{\"a}ltnis: W{\"a}hrend die Freiwilligenmangerin aktiv handelt, wird die freiwillig Engagierte zum Objekt von Management-Techniken. Dass dies dem Anspruch der Partizipation entgegenl{\"a}uft, ergibt sich dabei von selbst. Angesichts dieser Diagnose, dass real-existierendes Freiwilligenmanagement nicht mit dem Ideal des b{\"u}rgerschaftlichen Engagement im engeren Sinne zusammenpasst, formuliert das Fazit Vorschl{\"a}ge f{\"u}r ein b{\"u}rgerschaftlich orientiertes, engagement-sensibles Freiwilligenmanagement.

The combination of different carbohydrate-derived 1,2-dicarbonyl compounds and amino acids is a simple way to modulate the properties and introduce different functionalities. A representative compound was assessed as an acid catalyst, and converted into acidic ionic liquids by reaction with several strong acids. The reactivity of the double carboxylic functionality was explored by esterification with long and short chain alcohols, as well as functionalised amines, which led to the straightforward formation of surfactant-like molecules or bifunctional esters and amides. One of these di-esters is currently being investigated for the synthesis of poly(ionic liquids). The functionalisation of cellulose with one of the bifunctional esters was investigated and preliminary tests employing it for the functionalisation of filter papers were carried out successfully. The imidazolium zwitterions were converted into ionic liquids via hydrothermal decarboxylation in flow, a benign and scalable technique. This method provides access to imidazolium ionic liquids via a simple and sustainable methodology, whilst completely avoiding contamination with halide salts. Different ionic liquids can be generated depending on the functionality contained in the ImZw precursor. Two alanine-derived ionic liquids were assessed for their physicochemical properties and applications as solvents for the dissolution of cellulose and the Heck coupling.},

Der erste Schritt im Infektionszyklus ist die Anbindung des Viruses {\"u}ber sein Oberfl{\"a}chenprotein H{\"a}magglutinin (HA) an Zuckerstrukturen auf Epithelzellen des respiratorischen Traktes im Wirtsorganismus. Aus den drei komplementarit{\"a}tsbestimmenden Regionen (complementarity determining regions, CDRs) der schweren Kette eines monoklonalen H{\"a}magglutinin-bindenden Antik{\"o}rpers wurden drei lineare Peptide abgeleitet. Die Bindungseigenschaften der drei Peptide wurden experimentell mittels Oberfl{\"a}chenplasmonenresonanzspektroskopie untersucht. Es zeigte sich, dass in {\"U}bereinstimmung mit begleitenden Molekulardynamik-Simulationen zwei der drei Peptide (PeB und PeC) analog zur Bindef{\"a}higkeit des Antik{\"o}rpers in der Lage sind, Influenzaviren vom Stamm X31 (H3N2 A/Aichi/2/1968) zu binden. Die Interaktion des Peptids PeB, welches potentiell mit der konservierten Rezeptorbindestelle im HA interagiert, wurde anschließend n{\"a}her charakterisiert. Die Detektion der Influenzaviren war unter geeigneten Immobilisationsbedingungen im diagnostisch relevanten Bereich m{\"o}glich. Die Spezifit{\"a}t der PeB-Virus-Bindung wurde mittels geeigneter Kontrollen auf der Seite des Analyten und des Liganden nachgewiesen. Des Weiteren war das Peptid PeB in der Lage die Bindung von X31-Viren an Mimetika seines nat{\"u}rlichen Rezeptors zu inhibieren, was die spezifische Interaktion mit der Rezeptorbindungsstelle im H{\"a}magglutinin belegt. Anschließend wurde die Prim{\"a}rsequenz von PeB durch eine vollst{\"a}ndige Substitutionsanalyse im Microarray-Format hinsichtlich der Struktur-Aktivit{\"a}ts-Beziehungen charakterisiert.

Die hierf{\"u}r notwendigen Testsysteme werden kontinuierlich weiterentwickelt und neue Methoden aufgrund neuer Wirkstoffe der Pharmaindustrie etabliert. Gegenstand dieser Arbeit war es, eine parallele Mehrkomponentenanalyse auf Basis von Antigen-Antik{\"o}rper Reaktionen zu entwickeln, bei dem es prim{\"a}r um Verringerung des ben{\"o}tigten Probevolumens und der Versuchszeit im Vergleich zu einem Standard Nachweis-Verfahren ging. Neben der Verwendung eines Multiplex Ansatzes und der Mikroarraytechnologie stellten ebenfalls die Genauigkeit aller Messparameter, die Stabilit{\"a}t des Versuchsaufbaus sowie die Performance {\"u}ber einen Einfach-Blind-Ansatz Herausforderungen dar. Die Anforderung an den Multiplex Ansatz, keine falschen Signale trotz {\"a}hnlicher Strukturen zu messen, konnte durch die gezielte Kombination von spezifischen Antik{\"o}rpern realisiert werden. Hierf{\"u}r wurden neben Kreuzreaktivit{\"a}tstests auf dem Mikroarray parallel erfolgreich Western Blot Versuche durchgef{\"u}hrt. Jene Antik{\"o}rper, welche in diesen Versuchen die gesetzten Anforderungen erf{\"u}llten, wurden f{\"u}r das Ermitteln der kleinsten nachweisbaren Konzentration verwendet. {\"U}ber das Optimieren der Versuchsbedingungen konnte unter Verwendung von Tween in der Waschl{\"o}sung sowohl auf Glas als auch auf Kunststoff die Hintergrundfluoreszenz reduziert und somit eine Steigerung des Signal/Hintergrundverh{\"a}ltnisses erreicht werden. In den Versuchen zu Ermittlung der Bestimmungsgrenze wurde f{\"u}r das humane Choriongonadotropin (hCG-i) eine Konzentration von 10 mU/ml, f{\"u}r dessen beta-Untereinheit (hCG-beta) eine Konzentration von 3,6 mU/ml und f{\"u}r das luteinisierende Hormon (LH) eine Konzentration von 10 mU/ml bestimmt. Den ermittelten Wert im Serum f{\"u}r das hCG-i entspricht dem von der Welt-Anti-Dopin-Agentur (WADA) geforderten Wert in Urin von 5 mU/ml. Neben der Ermittlung von Bestimmungsgrenzen wurden diese hinsichtlich auftretender Matrixeffekte in Serum und Blut gemessen. Wie aus den Versuchen zur Ermittlung von Kreuzreaktivit{\"a}ten auf dem Mikroarray zu entnehmen ist, lassen sich das LH, das hCG-i und hCG-β ebenfalls in Serum und Blut messen. Die Durchf{\"u}hrung einer Performance-Analyse {\"u}ber einem Einfach-Blind-Ansatz mit 130 Serum Proben, wurde ebenfalls {\"u}ber dieses System realisiert. Die ausgewerteten Proben wurden anschließend {\"u}ber eine Grenzwertoptimierungskurve analysiert und die diagnostische Spezifit{\"a}t ermittelt. F{\"u}r die Messungen des LH konnte eine Sensitivit{\"a}t und Spezifit{\"a}t von 100\% erreicht werden. Demnach wurden alle negativen und positiven Proben eindeutig interpretiert. F{\"u}r das hCG-β konnte ebenfalls eine Spezifit{\"a}t von 100\% und eine Sensitivit{\"a}t von 97\% erreicht werden. Die hCG-i Proben wurden mit einer Spezifit{\"a}t von 100\% und eine Sensitivit{\"a}t von 97,5\% gemessen. Um den Nachweis zu erbringen, dass dieser Versuchsaufbau {\"u}ber mehrere Wochen stabile Signale bei Vermessen von identischen Proben liefert, wurde ein {\"u}ber zw{\"o}lf Wochen angesetzter Stabilit{\"a}tstest f{\"u}r alle Parameter erfolgreich in Serum und Blut durchgef{\"u}hrt. Zusammenfassend konnte in dieser Arbeit erfolgreich eine Mehrkomponentenanalyse als Multiplex Ansatz auf einem Mikroarray entwickelt werden.

  abstract  = {Reading is a complex cognitive task based on the analyses of visual stimuli. Due to the physiology of the eye, only a small number of letters around the fixation position can be extracted with high visual acuity, while the visibility of words and letters outside this so-called foveal region quickly drops with increasing eccentricity. As a consequence, saccadic eye movements are needed to repeatedly shift the fovea to new words for visual word identification during reading. Moreover, even within a foveated word fixation positions near the word center are superior to other fixation positions for efficient word recognition (O'Regan, 1981; Brysbaert, Vitu, and Schroyens, 1996). Thus, most reading theories assume that readers aim specifically at word centers during reading (for a review see Reichle, Rayner, \& Pollatsek, 2003). However, saccades' landing positions within words during reading are in fact systematically modulated by the distance of the launch site from the word center (McConkie, Kerr, Reddix, \& Zola, 1988). In general, it is largely unknown how readers identify the center of upcoming target words and there is no computational model of the sensorimotor translation of the decision for a target word into spatial word center coordinates. Here we present a series of three studies which aim at advancing the current knowledge about the computation of saccade target coordinates during saccade planning in reading. Based on a large corpus analyses, we firstly identified word skipping as a further factor beyond the launch-site distance with a likewise systematic and surprisingly large effect on within-word landing positions. Most importantly, we found that the end points of saccades after skipped word are shifted two and more letters to the left as compared to one-step saccades (i.e., from word N to word N+1) with equal launch-site distances. Then we present evidence from a single saccade experiment suggesting that the word-skipping effect results from highly automatic low-level perceptual processes, which are essentially based on the localization of blank spaces between words. Finally, in the third part, we present a Bayesian model of the computation of the word center from primary sensory measurements of inter-word spaces. We demonstrate that the model simultaneously accounts for launch-site and saccade-type contingent modulations of within-word landing positions in reading. Our results show that the spatial saccade target during reading is the result of complex estimations of the word center based on incomplete sensory information, which also leads to specific systematic deviations of saccades' landing positions from the word center. Our results have important implications for current reading models and experimental reading research.},

  abstract  = {Knowing the rates and mechanisms of geomorphic process that shape the Earth's surface is crucial to understand landscape evolution. Modern methods for estimating denudation rates enable us to quantitatively express and compare processes of landscape downwearing that can be traced through time and space—from the seemingly intact, though intensely shattered, phantom blocks of the catastrophically fragmented basal facies of giant rockslides up to denudational noise in orogen-wide data sets averaging over several millennia. This great variety of spatiotemporal scales of denudation rates is both boon and bane of geomorphic process rates. Indeed, processes of landscape downwearing can be traced far back in time, helping us to understand the Earth's evolution. Yet, this benefit may turn into a drawback due to scaling issues if these rates are to be compared across different observation timescales. This thesis investigates the mechanisms, patterns and rates of landscape downwearing across the Himalaya-Tibet orogen. Accounting for the spatiotemporal variability of denudation processes, this thesis addresses landscape downwearing on three distinctly different spatial scales, starting off at the local scale of individual hillslopes where considerable amounts of debris are generated from rock instantaneously: Rocksliding in active mountains is a major impetus of landscape downwearing. Study I provides a systematic overview of the internal sedimentology of giant rockslide deposits and thus meets the challenge of distinguishing them from macroscopically and microscopically similar glacial deposits, tectonic fault-zone breccias, and impact breccias. This distinction is important to avoid erroneous or misleading deduction of paleoclimatic or tectonic implications. -> Grain size analysis shows that rockslide-derived micro-breccia closely resemble those from meteorite impact or tectonic faults. -> Frictionite may occur more frequently that previously assumed. -> M{\"o}ssbauer-spectroscopy derived results indicate basal rock melting in the absence of water, involving short-term temperatures of >1500°C. Zooming out, Study II tracks the fate of these sediments, using the example of the upper Indus River, NW India. There we use river sand samples from the Indus and its tributaries to estimate basin-averaged denudation rates along a ~320-km reach across the Tibetan Plateau margin, to answer the question whether incision into the western Tibetan Plateau margin is currently active or not. -> We find an about one-order-of-magnitude upstream decay—from 110 to 10 mm kyr^-1—of cosmogenic Be-10-derived basin-wide denudation rates across the morphological knickpoint that marks the transition from the Transhimalayan ranges to the Tibetan Plateau. This trend is corroborated by independent bulk petrographic and heavy mineral analysis of the same samples. -> From the observation that tributary-derived basin-wide denudation rates do not increase markedly until ~150-200 km downstream of the topographic plateau margin we conclude that incision into the Tibetan Plateau is inactive. -> Comparing our postglacial Be-10-derived denudation rates to long-term (>10^6 yr) estimates from low-temperature thermochronometry, ranging from 100 to 750 mm kyr^-1, points to an order- of-magnitude decay of rates of landscape downwearing towards present. We infer that denudation rates must have been higher in the Quaternary, probably promoted by the interplay of glacial and interglacial stages. Our investigation of regional denudation patterns in the upper Indus finally is an integral part of Study III that synthesizes denudation of the Himalaya-Tibet orogen. In order to identify general and time-invariant predictors for Be-10-derived denudation rates we analyze tectonic, climatic and topographic metrics from an inventory of 297 drainage basins from various parts of the orogen. Aiming to get insight to the full response distributions of denudation rate to tectonic, climatic and topographic candidate predictors, we apply quantile regression instead of ordinary least squares regression, which has been standard analysis tool in previous studies that looked for denudation rate predictors. -> We use principal component analysis to reduce our set of 26 candidate predictors, ending up with just three out of these: Aridity Index, topographic steepness index, and precipitation of the coldest quarter of the year. -> Topographic steepness index proves to perform best during additive quantile regression. Our consequent prediction of denudation rates on the basin scale involves prediction errors that remain between 5 and 10 mm kyr^-1. -> We conclude that while topographic metrics such as river-channel steepness and slope gradient—being representative on timescales that our cosmogenic Be-10-derived denudation rates integrate over—generally appear to be more suited as predictors than climatic and tectonic metrics based on decadal records.},

  abstract  = {The characterization of exoplanets is a young and rapidly expanding field in astronomy. It includes a method called transmission spectroscopy that searches for planetary spectral fingerprints in the light received from the host star during the event of a transit. This techniques allows for conclusions on the atmospheric composition at the terminator region, the boundary between the day and night side of the planet. Observationally a big challenge, first attempts in the community have been successful in the detection of several absorption features in the optical wavelength range. These are for example a Rayleighscattering slope and absorption by sodium and potassium. However, other objects show a featureless spectrum indicative for a cloud or haze layer of condensates masking the probable atmospheric layers. In this work, we performed transmission spectroscopy by spectrophotometry of three Hot Jupiter exoplanets. When we began the work on this thesis, optical transmission spectra have been available for two exoplanets. Our main goal was to advance the current sample of probed objects to learn by comparative exoplanetology whether certain absorption features are common. We selected the targets HAT-P-12b, HAT-P-19b and HAT-P-32b, for which the detection of atmospheric signatures is feasible with current ground-based instrumentation. In addition, we monitored the host stars of all three objects photometrically to correct for influences of stellar activity if necessary. The obtained measurements of the three objects all favor featureless spectra. A variety of atmospheric compositions can explain the lack of a wavelength dependent absorption. But the broad trend of featureless spectra in planets of a wide range of temperatures, found in this work and in similar studies recently published in the literature, favors an explanation based on the presence of condensates even at very low concentrations in the atmospheres of these close-in gas giants. This result points towards the general conclusion that the capability of transmission spectroscopy to determine the atmospheric composition is limited, at least for measurements at low spectral resolution. In addition, we refined the transit parameters and ephemerides of HAT-P-12b and HATP- 19b. Our monitoring campaigns allowed for the detection of the stellar rotation period of HAT-P-19 and a refined age estimate. For HAT-P-12 and HAT-P-32, we derived upper limits on their potential variability. The calculated upper limits of systematic effects of starspots on the derived transmission spectra were found to be negligible for all three targets. Finally, we discussed the observational challenges in the characterization of exoplanet atmospheres, the importance of correlated noise in the measurements and formulated suggestions on how to improve on the robustness of results in future work.},

  abstract  = {Obwohl in den unionalen Vertr{\"a}gen bis heute keine Vorschrift bez{\"u}glich einer Staatshaftung der Mitgliedstaaten f{\"u}r Entscheidungen ihrer Gerichte existiert, hat der Gerichtshof der Europ{\"a}ischen Union (EuGH) in einer Reihe von Entscheidungen eine solche Haftung entwickelt und pr{\"a}zisiert. Die vorliegende Arbeit analysiert eingehend diese Rechtsprechung mitsamt den sich daraus ergebenden facettenreichen Rechtsfragen. Im ersten Kapitel widmet sich die Arbeit der historischen Entwicklung der unionsrechtlichen Staatshaftung im Allgemeinen, ausgehend von dem bekannten Francovich-Urteil aus dem Jahr 1991. Sodann werden im zweiten Kapitel die zur Haftung f{\"u}r judikatives Unrecht grundlegenden Entscheidungen in den Rechtssachen K{\"o}bler und Traghetti vorgestellt. In dem sich anschließenden dritten Kapitel wird der Rechtscharakter der unionsrechtlichen Staatshaftung - einschließlich der Frage einer Subsidiarit{\"a}t des unionsrechtlichen Anspruchs gegen{\"u}ber bestehenden nationalen Staatshaftungsanspr{\"u}chen - untersucht. Das vierte Kapitel widmet sich der Frage, ob eine unionsrechtliche Staatshaftung f{\"u}r judikatives Unrecht prinzipiell anzuerkennen ist, wobei die wesentlichen f{\"u}r und gegen eine solche Haftung sprechenden Argumente ausf{\"u}hrlich behandelt und bewertet werden. Im f{\"u}nften Kapitel werden die im Zusammenhang mit den unionsrechtlichen Haftungsvoraussetzungen stehenden Probleme der Haftung f{\"u}r letztinstanzliche Gerichtsentscheidungen detailliert er{\"o}rtert. Zugleich wird der Frage nachgegangen, ob eine Haftung f{\"u}r fehlerhafte unterinstanzliche Gerichtsentscheidungen zu bef{\"u}rworten ist. Das sechste Kapitel befasst sich mit der Ausgestaltung der unionsrechtlichen Staatshaftung f{\"u}r letztinstanzliche Gerichtsentscheidungen durch die Mitgliedstaaten, wobei u.a. zur Anwendbarkeit der deutschen Haftungsprivilegien bei judikativem Unrecht auf den unionsrechtlichen Staatshaftungsanspruch Stellung genommen wird. Im letzten Kapitel wird der Frage nachgegangen, ob der EuGH {\"u}berhaupt {\"u}ber eine Kompetenz zur Schaffung der Staatshaftung f{\"u}r letztinstanzliche Gerichtsentscheidungen verf{\"u}gte. Abschließend werden die wichtigsten Ergebnisse der Arbeit pr{\"a}sentiert und ein Ausblick auf weitere m{\"o}gliche Auswirkungen und Entwicklungen der unionsrechtlichen Staatshaftung f{\"u}r judikatives Unrecht gegeben.},

  abstract  = {Die vorliegende Studie besch{\"a}ftigte sich mit der Bedeutung der dysfunktionalen Einstellungen f{\"u}r die Entwicklung von depressiven Symptomen bei Kindern und Jugendlichen. Nach der kognitiven Theorie der Depression von Beck (1967, 1996) f{\"u}hren dysfunktionale Einstellungen in Interaktion mit Stress zu depressiven Symptomen. Es existieren allerdings nur wenige Studien, die die longitudinale Beziehung zwischen den dysfunktionalen Einstellungen und der Depressivit{\"a}t bei Kindern und Jugendlichen untersucht haben (Lakdawalla et al., 2007). Folglich kann noch nicht eindeutig gekl{\"a}rt werden, ob die dysfunktionalen Einstellungen Ursache, Begleiterscheinung oder Konsequenz der Depression sind. Als Datengrundlage diente eine Stichprobe von Kindern und Jugendlichen im Alter von 9 bis 20 Jahren, die im Rahmen der PIER-Studie zu dysfunktionalen Einstellungen, kritischen Lebensereignissen und depressiven Symptomen befragt wurden (Nt1t2 = 1.053; t1: 2011/2012, t2: 2013/2014). Querschnittliche Analysen zeigten hohe Assoziationen zwischen den dysfunktionalen Einstellungen, kritischen Lebensereignissen und depressiven Symptomen. Eine latente Moderationsanalyse wies nur bei den Jugendlichen auf signifikante Interaktion zwischen den dysfunktionalen Einstellungen und den kritischen Lebensereignissen in der Vorhersage depressiver Symptomatik hin. Im L{\"a}ngsschnitt zeigten latente Cross-Lagged-Panel-Analysen erwartungsgem{\"a}ß, dass die dysfunktionalen Einstellungen und die Depressivit{\"a}t mit dem Alter immer stabilere Konstrukte darstellen, die sehr eng miteinander zusammenh{\"a}ngen. Eine diesem Modell hinzugef{\"u}gte latente Moderationsanalyse konnte das kognitive Modell der Depression nach Beck weder bei Kindern noch bei Jugendlichen best{\"a}tigen. Die sp{\"a}tere depressive Symptomatik konnte lediglich durch Haupteffekte der fr{\"u}heren Auspr{\"a}gung der Depressivit{\"a}t und der kritischen Lebensereignisse vorhergesagt werden. Diese Ergebnisse legen den Schluss nahe, dass es sich bei den dysfunktionalen Einstellungen eher um Begleiterscheinungen als um Risikofaktoren oder Konsequenzen der depressiven Symptomatik handelt.},
