Diversity in Reinforcement Learning
(2026-08-04)Reinforcement learning is a machine learning paradigm that aims to develop optimal policies for discrete-time control problems based on quantitative feedback on the learner’s behaviour. Reinforcement learning is formulated ... -
Knowledge-Driven Intelligent Systems for Precision Agriculture: A Demonstration on Disease Spread Prediction
(2026-08-04)Organic cultivation, resource efficiency, and sustainability are gaining increasing importance in times of climate change. To address these issues, modern agriculture is increasingly relying on the use of drones to monitor ... -
CCL17DTR mice as a new mouse model of epilepsy
(2026-08-04)Epilepsy is a serious neurodegenerative disease affecting millions of people worldwide. Patients suffer from unpredictable seizure episodes that drastically impair the quality of life. Approximately one third of epilepsy ... -
Systematische Quantifizierung des mitochondrialen Imports von Präproteinen unter proteotoxischen Bedingungen
(2026-08-04)Die Analyse von Mitochondrien ist ein wichtiger Indikator für den Gesundheitszustand einer Zelle und es wurde in den letzten Jahren immer deutlicher, dass die Untersuchung der Mitochondrien in vielen Krankheiten immer mehr ... -
The GDH sum rule and extension to photoproduction off neutron targets in the Jülich-Bonn model
(2026-08-03)In this thesis, the light baryon spectrum of nucleon and delta resonances is stud- ied up to center-of-mass energies of 2.5 GeV. In this energy region, the strong interaction is non-perturbative and other methods are ... -
Endocrine-disrupting nonylphenols: Determination in food samples and isomer-specific analysis
(2026-07-29)Nonylphenols (NPs) are degradation products of 4-nonylphenol ethoxylates (NPEs). NPEs are non-ionic surfactants that have been used for decades in cleaning agents and industrial processes due to their surfactant activity. ... -
Identification of a Hsp40 Involved in the Cytosolic Quality Control of Mitochondrial Precursor Proteins
(2026-07-28)(noch nicht zugänglich / not yet accessible) -
Non-reversible Lifts of Reversible Diffusions and their Convergence to Equilibrium
(2026-07-28)This thesis is concerned with convergence to stationarity of non-reversible Markov processes with degenerate noise, known as hypocoercivity. We develop a framework that allows to derive rates of convergence towards the ... -
Fast micro thermal desorption combined with cryofocusing for ultra fast gas chromatography
(2026-07-28)In safety research, gas chromatography is a commonly used technique for the detection of hazardous substances in air samples for example. When public safety is at risk and decisions about protective measures must be made, ... -
Coupled high-finesse optical Fabry-Pérot microcavities
(2026-07-28)Dissipation is unavoidable in any realistic physical system and can strongly reshape its dynamics and spectra. Coupled cavity systems offer a minimal and highly controllable setting in which coherent photon exchange competes ... -
Development of a Parameter Estimation Pipeline for Multi-Cellular Biological Processes
(2026-07-28)Tissue dynamics are complex and involve interactions between different cell types and extracellular components on different spatial and temporal scales. Specific tissue properties are relevant for a broad range of processes, ... -
The Role of Microtubule Retrograde Flow in Neuronal Development
(2026-07-24)The microtubule array in developing neurons consists of more than a hundred microtubules in each neurite. This microtubule array has been thought to act as stationary tracks, in which only individual microtubules are dynamic ... -
Nachhaltige Anwendungen für die Titanocenkatalysierte Hydrosilylierung
(2026-07-24)Die vorliegende Arbeit befasst sich mit der Weiterentwicklung der titanocenkatalysierten Hydrosilylierung. Die Reaktion ermöglicht es, aus Epoxiden anti-Markownikow-Alkohole herzustellen, und ist damit komplementär zur ... -
Transport mechanisms of bacterial membrane proteins analyzed by advanced fluorescence microscopy
(2026-07-24)Transporter proteins are integral membrane proteins and enable the translocation of hydro- or amphiphilic substrates over cell membranes. This study focuses on two such systems: The lipid II flippase and the tripartite ... -
Design, Synthesis and Characterization of Potent and Selective Adenosine A2B Receptor Agonists

From Efficient Geomorphological Mapping to Semi-Automated Landslide Detection
(2026-07-14)Detailed geomorphological mapping is a fundamental tool for understanding landform evolution and landslide processes; however, conventional field-based approaches remain time-consuming, expert-dependent, and spatially ... -
Mathematical modeling and efficient simulation of epidemic metapopulation dynamics: Integrating mobility, behavior, and machine learning
(2026-07-13)Infectious disease modeling faces an inherent tension between physical realism and computational feasibility. Granular metapopulation models offer interpretability and the capacity to resolve complex behavioral dynamics ... -
The differentiable stack cohomology associated to a regular and proper Lie groupoid
(2026-07-10)This thesis establishes a model for the differentiable stack cohomology associated to a regular and proper Lie groupoid. <br/> The 2-category of differentiable stacks is equivalent to a 2-category of Lie groupoids, which ... -
Physical and chemical characterization of Galactic HII regions
(2026-07-09)High-mass stars (> 8 M<sub>⊙</sub>) play a crucial role in shaping the dynamics and evolution of the interstellar medium (ISM) and galaxies, through their intense radiation, powerful stellar winds, shocks, and supernova ... -
Silicon Detector Development for Future Lepton Colliders & Quality Control of the ATLAS Strip Tracker Production
(2026-07-09)Future high energy physics aims to probe the Standard Model with unprecedented precision, through upgrades of existing collider experiments and the development of future collider facilities. Achieving the ambitious physics ...
