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 ... -
