The Never-Ending Story of Authentication: Investigating Password Composition Policies and Second-Factor Recoverability
(2025-01-10)Authentication is an area where users regularly encounter IT security, and it has been studied in the field of usable IT security for at least 25 years. There are numerous proposals and ideas to improve the IT security of ... -
Functionalized Biaryls as Building Blocks for Non-Aggregating Molecular Spoked Wheels
(2025-01-08)Molecular spoked wheels (MSWs) showed to be synthetically accessible in various sizes and functionalization in the past. Due to their construction of not only phenylene- but also acetylene- and bisacetylene-units, some of ... -
Photoredoxkatalysen mit Titanocenen
(2025-01-08)Titanocen-Katalysatoren bieten vielfältige Anwendungsmöglichkeiten in verschiedensten chemischen Reaktionen. In der vorliegenden Arbeit wurden elektrochemische und photochemische Methoden sowie das Konzept der Additiv-un ... -
Combinatorial aspects of bow varieties
(2025-01-08)First introduced by Cherkis in theoretical physics, bow varieties form a rich family of symplectic varieties generalizing Nakajima quiver varieties. An algebro-geometric definition was later given by Nakajima and Takayama ... -
Large-Scale X-ray Studies of Nearby Galaxy Clusters with eROSITA
(2025-01-07)Galaxy clusters form in the intersections of the cosmic web and grow through mergers and accretion of smaller substructures transported by the cosmic filaments. Hence, the outskirts of galaxy clusters are of great significance ... -
Methods and tools for studying ecto-5'-nucleotidase (CD73)
(2024-12-17)(noch nicht zugänglich / not yet accessible) -
Generation, characterization, and potential food applications of a novel red colorant formed by oxidative coupling of chlorogenic acid and tryptophan
(2024-12-17)Due to growing consumer skepticism regarding synthetic food colorants and their potential health effects and environmental impact, there is a rising interest in novel natural compounds derived from plants. A red-colored ... -
Rapid 3D Whole Brain Molecular MRI at 7T
(2024-12-17)Magnetic resonance imaging (MRI) has emerged as a leading, non-ionizing diagnostic tool in medical practice over the last decades. Beyond, MRI has evolved into an expansive field of research, yielding a multitude of novel ... -
Combining Ecohydrological Catchment Modeling and Water Quality Monitoring Data to Assess Nitrogen Pollution in the Swist River Basin, Germany
(2024-12-17)Legislation like the EU Water Framework Directive demands the development as well as implementation of catchment-scale monitoring and management plans to control pollution of surface waters and ensure their good status. ... -
Biosynthesis and biotechnological application of the glycine-glucolipid from the marine bacterium Alcanivorax borkumensis
(2024-12-17)(noch nicht zugänglich / not yet accessible) -
Subtrajectory Clustering, Curve Averaging and the Complexity of Underlying Range Spaces
(2024-12-13)In this thesis, we study the clustering of spatial data with a focus on trajectory data. Trajectory data appears in various applications. These range from the recorded positions of moving objects (e.g. animals, humans, ... -
Spin Labeling with Nitroxide, Trityl, and Copper Labels for Protein Structure Elucidation by EPR Spectroscopy
(2024-12-13)In this thesis, the intricate challenges that emerge in the application of site-directed spin labeling (SDSL) techniques for structural investigation of biomolecules are addressed, with a specific focus on nitroxide, trityl ... -
Mathematical modelling of complete recessive lethals: Adaptive dynamics across varying genetic and population structures
(2024-12-12)The study of recessive lethal diseases in populations presents significant challenges, from estimating key parameters - such as the number of genes involved and the mutation rates driving genetic degeneration - to understanding ... -
Some sharp and endpoint inequalities in Harmonic Analysis
(2024-12-12)This cumulative dissertation is dedicated to the study of certain sharp and endpoint inequalities in Harmonic Analysis. <br /> The first part of this thesis focuses on sharp Fourier extension inequalities on spheres. Our ... -
Epigenetische Modulation der Heparansulfat-Sulfotransferasen-Expression in Mammakarzinomzellen und Einflussnahme auf die Tumorzell-induzierte Thrombozytenaktivierung
(2024-12-11)Disseminierte Tumorzellen profitieren erheblich von der Interaktion mit Thrombozyten. Durch eine Tumorzell-induzierte Thrombozytenaktivierung (TCIPA) kommt es zur Ausbildung von Heteroaggregaten, durch die sich die entarteten ... -

Defect-Free Atom Arrays of 88Sr in Optical Tweezers
(2024-12-03)Neutral atoms trapped in optical microtraps, so called optical tweezers, have emerged as a platform for controlling large many-particle quantum systems, with applications in many-body physics, metrology, quantum information ... -
Relevance of Crumbs homolog 2 in the Glomerular filtration barrier
(2024-12-02)Mammalian podocytes not only form the final layer within the glomerular filtration barrier (GFB) but also withstand enormous pressure that essentially drives renal ultrafiltration. Their effacement has been linked with and ... -
Non-equilibrium situations and shear flows in kinetic theory and fluid mechanics
(2024-11-28)In this thesis two models are studied: the Boltzmann equation and the incompressible Euler-Poisson equation. Concerning the Boltzmann equation we analyze the longtime behavior of so-called homoenergetic solutions in specific ... -
Modelling Fog and Low Stratiform Clouds in the Namib Desert with COSMO-FOG
(2024-11-28)The Namib Desert – one of the driest regions on earth – is a typical coastal desert with very scarce rainfall and regularly occurring fog. Fog water input often exceeds rainfall and thus fog water deposition is a major ...
