The redshift evolution of galactic-scale magnetic fields
Kovács, Tímea (2024-06-27)Magnetic fields play an important role in galaxy evolution, however, the redshift evolution of galactic-scale magnetic fields is not well constrained, with only a handful of direct magnetic field strength measurements in ... -
Formulation Development and Optimization via In Vivo Predictive In Vitro and In Silico Tools
Becker, Tim (2024-06-25)(noch nicht zugänglich / not yet accessible) -
Identification of molecular mechanisms that may contribute to the antidepressant effect of St. John's wort extract Ze 117
Bremer, Swen (2024-06-25)Chronic stress is one of the factors that contribute to the development and maintenance of depression. Previous studies have shown that the treatment of cultured cells with the natural stress hormone cortisol, but also ... -
On discrete Morse theory in persistent topology
Brüggemann, Julian Jürgen Paul (2024-06-25)The main topic of this thesis is the interplay between discrete Morse theory and persistent topology: we apply methods from discrete Morse theory to filtered complexes, as they appear in Topological Data Analysis, and study ... -
Kondo Collapse and Revival by Pulsed Light
Costa Meirinhos, Francisco (2024-06-24)The search and characterisation of new quantum phases of matter has recently been intensified by the application of terahertz (THz) spectroscopy in the time domain to heavy-fermion systems. It was experimentally shown that ... -
Modulation of filamin C interactions and function by mechanical stress-induced phosphorylations
Heil, Lorena (2024-06-24)(noch nicht zugänglich / not yet accessible) -
Deep Representation Learning for Analyzing Financial and Cybersecurity Data
Biesner, David (2024-06-19)Recent years have shown a surge in the capability of deep learning models for various domains of interest and different types of data. Machine learning models are now capable of understanding, categorizing and generating ... -
Higgs Mode and Critical Temperature in the BCS-BEC Crossover
Breyer, Moritz (2024-06-19)For this thesis, analogue quantum simulations of the BCS-BEC crossover have been performed. To this end, an ultracold gas of fermionic <sup>6</sup>Li atoms was prepared in an optical dipole trap. The gas is in a balanced ... -
Phenanthracene Nanotubes for Template-designed Organic Electronics
Rickert, Simon Christian (2024-06-19)The overall increasing energy consumption worldwide demands for new fundamental research that can contribute to mitigate its negative ecological effects. One such valuable field of research is the area of organic electronics. ... -
Search for solar axions using a 7-GridPix IAXO prototype detector at CAST
Schmidt, Sebastian Michael (2024-06-17)The Standard Model of particle physics describes three out of four known fundamental forces of nature very successfully. However, open questions remain. One of these, the 'strong CP problem', asks why the neutron has no ... -
Deciphering Effector Protein Functions of Ustilago maydis involved in gall formation
Bahrami, Pouria (2024-06-14)(noch nicht zugänglich / not yet accessible) -
Alignment of Highly Resolved Time-Dependent Experimental and Simulated Crash Test Data
Garcke, Jochen; Hahner, Sara; Iza-Teran, Rodrigo (2022-05)We investigate for car and component crash tests the comparison of highly resolved experimental data with corresponding simulation data. Due to re- cent advances for optical measurement systems, one can nowadays obtain ... -
Divergent Chemistry of Ditetrelynes (E2R2, E = Si, Ge) with Late Transition Metals and Low-valent Silicon Precursors
Palui, Prasenjit (2024-06-12)In modern inorganic chemistry, achieving “gram-scale syntheses” of compounds featuring elements in unusually low oxidation states with unconventional bonding modes continues to be a central goal. Successful isolation of ... -
Modern techniques and applications for (imaginary-)time evolution of quantum spin systems
Tepaske, Maurits Sebastiaan Joseph (2024-06-10)Causality is at the core of physics, with any physical phenomena boiling down to a sequence of states related by causality. If the sequence is repeating itself, it is in equilibrium, whereas a changing sequence indicates ... -
Wandel und Beharrung von regionalen Haushalts- und Familienstrukturen: Entwicklungsmuster in Deutschland im Zeitraum 1871 - 1978
Kemper, Franz-Josef (1997)Die vorliegende Studie beruht auf einer Habilitationsarbeit, die 1988 fertiggestellt und an der Mathematisch-Naturwissenschaftlichen Fakultät der Universität Bonn eingereicht wurde. Aufgrund von anderweitigen Verpflichtungen ... -
Die Einflüsse der Geopolitik auf Forschung und Theorie der Politischen Geographie von ihren Anfängen bis 1945: Ein Beitrag zur Wissenschaftsgeschichte der Politischen Geographie und ihrer Terminologie unter besonderer Berücksichtigung von Militär- und Kolonialgeographie
Kost, Klaus (1988)Die vorliegende Arbeit ist als Dissertation am Institut für Wirtschaftsgeographie der Universität [Bonn] entstanden. Sie basiert auf einer intensiven Beschäftigung mit der deutschen Geschichte der Neuzeit sowie mit Themen ... -
Deep Learning for Causal Inference and Latent Dynamical Modeling in Biomedical Research
Lagemann, Kai Andre (2024-06-03)Biological systems are ubiquitous, encompassing complex molecular networks governing single-cell organisms to expansive ecosystems profoundly impacting our planet's environment. In biology, the adoption of a systems approach ... -

Weber, Markus (2024-06-03)Die vorliegende Dissertation befasst sich mit der Entwicklung neuer Katalysatormaterialien für die Selektivoxidation kurzkettiger Kohlenwasserstoffe. Dabei wurden drei verschiedene konzeptionelle Ansätze verfolgt.<br/> Es ... -
A mass-conserving sparse grid combination technique with biorthogonal hierarchical basis functions for kinetic simulations
Pollinger, Theresa; Rentrop, Johannes; Pflüger, Dirk; Kormann, Katharina (2022-09)The exact numerical simulation of plasma turbulence is one of the assets and challenges in fusion research. For grid-based solvers, sufficiently fine resolutions are often unattainable due to the curse of dimensionality. ... -
Simrank-based prediction of crash simulation similarities
Pakiman, Anahita; Garcke, Jochen; Schumacher, Axel (2022)Data searchability has been utilized for decades and is now a crucial ingredient of data reuse. However, data searchability in industrial engineering is essentially still at the level of individual text documents, while ...
