Investigation of Surface Dynamics on Oxidized Metal Surfaces Using Ion Imaging Techniques
(2025-11-12)Heterogeneous catalysis plays a pivotal role in modern life, with applications ranging from the Haber-Bosch process over ethylene epoxidation to exhaust conversion in modern three-way catalysts in automobiles. While these ... -
Computational analysis of nucleosome assembly and cis-regulatory DNA elements
(2025-11-12)Induced pluripotent stem cells (iPSCs) represent embryonic stem cells (ESCs) that are reprogrammed from somatic stem cells. iPSCs can be directed to differentiate into any cell type in the human body, therefore, holding ... -
Land-use trajectories in lowland Sumatra: Impacts on leaf area index and below-canopy temperatures
(2025-11-12)Land-use change is widespread across the globe, leading to significant biodiversity loss and impairing ecosystem functions. The land-use trajectories from forest to agriculture contributes to increased surface and air ... -
Comparative Cognitive Flexibility Assessment: Multidimensional set-shifting in monkeys, adult humans and children and adolescents with Attention Deficit Hyperactivity Disorder (ADHD)
(2025-11-10)This thesis aims to provide a be0er and more comprehensive understanding of one of the crucial execu8ve func8ons: cogni8ve flexibility (Chapters 2 and 3). To that end, we have developed a novel mul8-dimensional set-shiEing ... -
Nonlinear Parsimonious Modeling with Information Filtering Networks: Theory and Practice
(2025-11-06)This thesis offers a comprehensive exploration and methodological advancement of Information Filtering Networks (IFNs), emphasizing Triangulated Maximally Filtered Graphs (TMFG), Local-Global (LoGo) models, and their ... -
International aid for biodiversity conservation policy in Central Africa: symbolic politics, empowerment and implications for inequalities
(2025-11-05)The Congo Basin Forest in Central Africa is the world's second largest tropical rainforest and is widely recognised as a global public good. Since the 1980s, international aid for biodiversity conservation in the region ... -
Capturing exciton wavefunctions by time-resolved photoemission orbital tomography
(2025-11-05)Excitons are realizations of a correlated many-body wavefunction, consisting of a Coulomb-bound electron and hole pair. They are the dominant excitations in semiconducting organic and low-dimensional quantum materials and ... -
A real effective version of the Freĭman-Scourfield Theorem
(2025-11-04)We study the solvability of a Diophantine equation with mixed real exponents for sufficiently large natural numbers. The connection to a condition on the sum over the reciprocals of the exponents was first shown by Freĭman ... -
Monitoring of Fusarium species on oats in Germany - identification, mycotoxin production and cultivar effects
(2025-11-04)The use of oats in human nutrition has increased in recent years due to their beneficial nutritional components. Nonetheless, with the implementation of new legal limits, elevated levels of mycotoxins in the harvested ... -
Optimierung der Diagnostik von der Posttraumatischen Belastungsstörung und der komplexen Posttraumatischen Belastungsstörung nach ICD-11
(2025-10-30)The establishment of the diagnosis of complex post-traumatic stress disorder (cPTSD) in the new classification system (ICD-11) has brought with it new diagnostic procedures. However, these procedures do not differentiate ... -
Role of bacterial rhamnolipids in plant tolerance to abiotic stresses
(2025-10-29)Rhamnolipids (RLs), glycolipids produced by Pseudomonas and Burkholderia species, have been described as potential biocontrol agents due to their antagonistic activity against pathogens and their ability to induce plant ... -
