Advances in camera, laser and computation technologies have enabled an ever-increasing number of imaging technologies. Imaging with visible and infrared light has the advantage that it is less harmful than other radiation and its wavelength is in the order of magnitude of cells and subcellular components. Fluorescence microscopy provides good chemical contrast and multi-colour imaging can help elucidate cellular architecture. Incoherent superresolution methods permit us to bypass Abbe's diffraction limit of lateral resolution and visualize previously unnoticed details. Coherent imaging methods such as optical coherence tomography or holoscopy do not require any previous labelling and have the advantage that they record both the amplitude and phase of the light emitted from a scattering sample by interferometric superposition with a reference wave.

### Title: ['Development of a holoscopic imaging system and applied high-resolution fluorescence microscopy']
### Abstract:
["Biomedical imaging helps extending our comprehension of ourselves and our environment. Advances in camera, laser and computation technologies have enabled an ever-increasing number of imaging technologies. Imaging with visible and infrared light has the advantage that it is less harmful than other radiation and its wavelength is in the order of magnitude of cells and subcellular components. Fluorescence microscopy provides good chemical contrast and multi-colour imaging can help elucidate cellular architecture. Incoherent superresolution methods permit us to bypass Abbe's diffraction limit of lateral resolution and visualize previously unnoticed details. Coherent imaging methods such as optical coherence tomography or holoscopy do not require any previous labelling and have the advantage that they record both the amplitude and phase of the light emitted from a scattering sample by interferometric superposition with a reference wave. Both incoherent an coherent imaging methods are used in this thesis. The results of two interdisciplinary research collaborations using different fluorescence microscopy methods, including superresolution methods, are presented. Podosomes in macrophages were studied with stimulated emission depletion microscopy, structured illumination microscopy and localisation microscopy and a distinctly polygonal shape in their vinculin rings was found. Image processing routines allowed for a quantitative analysis of the acquired images [1].

While economic diversification can provide valuable new social choices and capabilities, it also tends to lead to more complex decision processes and changes to the set of capabilities required by people to self-determine their future. Within this process of structural transformation, social networks are crucial for accessing information and social support, but networks can also be a root cause of exclusion and inequality reproduction. This implies the need to encourage innovation and economic diversification beyond production expansion, focusing on the promotion of human agency and social inclusion. This book provides such a modern perspective on development economics, emphasizing the role of social networks, economic diversity and entrepreneurship for social welfare. The author discusses how innovation, social networks, economic dynamics and human development are interlinked, and provides several practical examples of social and micro-entrepreneurship in contexts as diverse as Peruvian rural villages and Brazil’s urban areas. The interdisciplinary perspective put forward in this book illustrates theoretical and methodological methods of exploring the complexity of development in a practical and relevant way.

3A897838106.jsonld | ['Asymptotic safety in QFT : from quantum gravity to graphene'] | ["In this work we investigate properties of scale invariant theories. This kind of theories describe a variety of phenomena, and two particular examples are discussed. On the one hand, more than 100 years after the discovery of General Relativity by Einstein, we still don't know how to unify gravity and quantum mechanics. One possibility is that on very small scales, gravity could be scale invariant, allowing for a finite ultraviolet completion. On the other hand, we will study the phase diagram of graphene and related materials.

### Title: ['Asymptotic safety in QFT : from quantum gravity to graphene']
### Abstract:
["In this work we investigate properties of scale invariant theories. This kind of theories describe a variety of phenomena, and two particular examples are discussed. On the one hand, more than 100 years after the discovery of General Relativity by Einstein, we still don't know how to unify gravity and quantum mechanics. One possibility is that on very small scales, gravity could be scale invariant, allowing for a finite ultraviolet completion. On the other hand, we will study the phase diagram of graphene and related materials. Scale invariant points in phase diagrams are related to second order phase transitions, and near these universal behaviour is found. To investigate these systems, nonperturbative renormalisation group methods are used. In order to achieve trustworthy results, also technical progress, both analytical and numerical, had to be made. On the analytical side, the Mathematica package xAct is used to derive the equations underlying the scale invariance of the theories. To solve these numerically, pseudo-spectral methods are systematically introduced in the present context for the first time. The results thus obtained support the ultraviolet completion of gravity by a scale invariant point. The dependence on gauge fixing and parametrisation is investigated, and found to be reasonably small. The 2-loop counterterm, being the hallmark of the perturbative nonrenormalisability of gravity, is shown to be irrelevant at the scale invariant point.

3A898457173.jsonld | ['Extending the x-ray study of membrane fusion in supported multibilayers towards physiological conditions'] | ['Previously, our group successfully characterized the effect of various lipids on the stalk formation in pure lipid multibilayers by means of x-ray scattering. In this model system, the energy required for stalk formation was supplied by the osmotic pressure of the aqueous vapor. Despite its remarkable simplicity and effi ciency, the sample environment of this method was distinct from the fusion sites in vivo. This work aims to extend the x-ray study of stalk formation to more physiological conditions. To this end, efforts on three levels have been devoted, namely the lipid level, the peptide level and the protein level.

### Title: ['Extending the x-ray study of membrane fusion in supported multibilayers towards physiological conditions']
### Abstract:
['Previously, our group successfully characterized the effect of various lipids on the stalk formation in pure lipid multibilayers by means of x-ray scattering. In this model system, the energy required for stalk formation was supplied by the osmotic pressure of the aqueous vapor. Despite its remarkable simplicity and effi ciency, the sample environment of this method was distinct from the fusion sites in vivo. This work aims to extend the x-ray study of stalk formation to more physiological conditions. To this end, efforts on three levels have been devoted, namely the lipid level, the peptide level and the protein level. On the lipid level, PEG solutions rather than aqueous vapor were used as the stressor to promote stalk formation in pure lipid bilayers. On the peptide level, D-β-peptides were incorporated into model lipid multibilayers to investigate its transmembrane behaviors. Lastly, on the protein level, a novel solvent-free protocol was developed, and SNAREs, a family of proteins which mediate vesicle fuion, were reconstituted into the multibilayers via the micelle-vesicle-multibilayer pathway.']

In this work we focus on the stream-based learning, since it has several advantages over the conventional, batch-based learning.

This is an essential feature for real-life recommender systems, as their application scenarios are highly dynamic. Therefore, new information typically appears at a high rate. - Our first type are forgetting methods for stream-based recommender systems. Selecting what information to forget is equivalent to selecting which information to learn from. We propose eleven different forgetting strategies that select the obsolete information to be forgotten and three different algorithms that enforce forgetting on a stream of ratings. We stress that obsolete information is not necessarily old. Next to incorporating new information into a preference model, our forgetting techniques are the second way of adapting to concept drift or shift. - In our second type of selective learning we introduce selective neighbourhood for collaborative filtering methods. It encompasses a novel selection criterion based on the Hoeffding Bound for removing unreliable users from a neighbourhood. Our criterion considers both, the number of common ratings between users and the value of their similarity. - Our last selective approach is based on semi-supervised learning (SSL) for stream-based recommender systems. In this approach a recommender system exploits the abundant unlabelled information (user-item-pairs without ratings), which, typically, reaches 99% of all information. - To exploit this information for training of preference models we propose the first stream-based semi-supervised recommendation framework. In semi-supervised learning, predictions are used as labels. However, not all predictions are equally reliable.
