Site-Directed Spin Labeling of Large Riboswitches Using Click Chemistry
Kerzhner, Mark (2019-02-14)Due to the conformational variability of riboswitches, their structural analysis is of a great importance. The most frequently used techniques to investigate dynamic processes within the riboswitches are NMR and FRET. EPR ... -
Sleep and navigation in Drosophila
Flores-Valle, Andres (2023-12-20)Sleep plays an essential role in life and is critical for the optimal functioning of the brain, for example in learning and memory. Drosophila displays many of the signatures of sleep observed in mammals or humans, including ... -
Slow Atomic Beams Manipulation with Magnetic Videotapes
Mérimèche, Habib (2004)Laser cooling methods provide the possibility to obtain very well collimated and slow atomic beams. These intense sources have attracted new interest in the manipulation of atomic trajectories. Atom optical schemes based ... -
Small embeddings, forcing with side conditions, and large cardinal characterizations
Njegomir, Ana (2019-09-26)In this thesis, we provide new characterizations for several well-studied large cardinal notions. These characterizations will be of two types. Motivated by seminal work of Magidor, the first type characterizes large ... -
Small Molecules, Big Impact: Investigating Hydrides in the Interstellar Medium
Jacob, Arshia Maria (2021-06-16)This thesis investigates hydride molecules in the interstellar medium (ISM) and their use as diagnostics of different phases of the ISM. Particular emphasis is given to the central CH radical, a probe of diffuse and ... -
Small-scale Physical and Chemical Structure of Diffuse and Translucent Molecular Clouds along the Line of Sight to the Galactic Center
Thiel, Vivien (2019-05-02)Diffuse and translucent molecular clouds constitute a large part of the molecular interstellar medium (ISM) in our Galaxy as well as in other spiral galaxies. In particular, the envelopes of giant molecular clouds (GMCs), ... -
Small-scale studies of the Milky Way disc and halo gas with absorption-line spectroscopy
Nasoudi Shoar, Soroush (2012-12-13)Progressive studies in the last decades have shown that the interstellar medium (ISM) is more complex and dynamic than previously thought. The presence of the small-scale structures, structures on scales below 1 pc, has ... -
SMNrp und TUBA: Isolierung und Charakterisierung zweier neuer Gene mit Homologie zu SMN, dem Krankheitsgen der spinalen Muskelatrophie
Plöttner, Oliver (2002)Spinale Muskelatrophie, die zweithäufigste autosomal rezessive Erbkrankheit mit Todesfolge beim Menschen, wird durch Mutationen im SMN1-Gen verursacht, die zu einem Mangel an funktionellem SMN-Protein in den Zellen ... -
Smooth 4-Manifolds and Surface Diagrams
Behrens, Stefan (2014-06-18)Surface diagrams are a diagrammatic representation of smooth, 4-dimensional manifolds. In fact, a surface diagram encodes a 4-manifold together with a map onto the 2-sphere. After giving a detailed proof of this correspondence, ... -
Smoothed Analysis of Selected Optimization Problems and Algorithms
Brunsch, Tobias (2014-03-20)Optimization problems arise in almost every field of economics, engineering, and science. Many of these problems are well-understood in theory and sophisticated algorithms exist to solve them efficiently in practice. ... -
Social-aware Robot Navigation based on Deep Reinforcement Learning
Zhou, Yanying (2024-04-24)With the increase of applications involving autonomous mobile robots, there is a growing need for them to navigate safely and effectively in environments shared with humans. In recent years, social-aware robot navigation ... -
Soft tissue preservation in amber: a comparative study on the taphonomy and limits of fossilisation of resin embedded arthropods
Barthel, Hans Jonas (2022-11-02)This doctoral thesis deals with the limits of morphological and biomolecular preservation of fossils in amber and provides new information on their taphonomy. A particular focus lies on arthropod inclusions from Cambay and ... -
Software Security Metrics for Malware Resilience
Langweg, Hanno (2008)We examine the level of resistance offered by a software product against malicious software (malware) attacks. Analysis is performed on the software architecture. This is available as a result of the software design process ... -
Software Supply Chain Angriffe: Analyse und Erkennung
Ohm, Marc-Philipp (2021-09-29)Moderne Softwareentwicklung profitiert in vielen Hinsichten von der ausgiebigen Wiederverwendung externer Softwaremodule. Die Abhängigkeit von externen und somit schwer zu kontrollierenden Softwaremodulen – welche in ihrer ... -
Soil characteristics and soil erosion by water in a semi-arid catchment (Wadi Drâa, South Morocco) under the pressure of global change
Klose, Anna (2009-11-24)Soil resources are crucial for the well-being of man and the environment. The results of the first Global Assessment of Human-induced Soil Degradation (GLASOD) indicate that 13% of the world’s soils are degraded; thereof ... -
Soil degradation by water erosion in a sub-humid West-African catchment: a modelling approach considering land use and climate change in Benin
Hiepe, Claudia (2008)Soil degradation threatens agricultural production and food security in Sub-Saharan Africa. In the coming decades, soil degradation, in particular soil erosion, will become worse through the expansion of agriculture into ... -
Soil Moisture Analysis Based On Microwave Brightness Temperatures: A Study on Systematic and Random Errors
Wilker, Henning (2007)In the context of the EU research project ELDAS, the European Centre for Medium-Range Weather Forecasts developed an experimental soil moisture analysis system which is able to assimilate both screen-level variables (2-metre ... -
