Conditional Stability and Instability Estimates for Inverse Random Source Problems
(2026-01-13)This thesis is motivated by the study of passive imaging problems. Such problems can be characterised as scattering problems under uncontrolled incident waves. We focus specifically on inverse random source problems, a ... -
Basement-Cover Relationships in the Dom Feliciano Belt
(2026-01-08)The interaction of the main cratons that constitute the present-day configuration of South America and Africa, together with several minor blocks, led to the amalgamation of Southwest Gondwana in the late Neoproterozoic, ... -
Single Step Genomics: Methods and Implementation in German Cattle Populations
(2026-01-08)Genomics and genomic technologies have significantly advanced the development of many plant and livestock populations. However, their impact on beef cattle populations, particularly in Germany, has been limited. This thesis ... -
Multi-layered proteogenomic characterization of mouse brain aging in physiology and disease
(2026-01-06)Functional decline and increased susceptibility to neurodegenerative disease are the result of a complex interplay of molecular changes that accompany brain aging. These changes include accumulation of cellular damage, ... -
Structural Complexity and Biomass of Mountain Forests in the Annapurna Region, Himalaya
(2026-01-06)Heterogeneous environmental conditions characterize mountain forests and can be highly dynamic due to climatic and socio-economic changes. Despite their importance, our understanding of forests in the Himalaya is limited, ... -
Food Consumption and Malnutrition: Machine Learning Applications and Agricultural Trade Analysis
(2026-01-06)Consumers’ nutritional health status is facing significant global challenges, including malnutrition, obesity, and overweight-related health risks. The persistent high consumption of meat further exacerbates resource ... -
A robust, automated nudged elastic band method in internal coordinates
(2025-12-18)In this work, a robust and reliable implementation of the Nudged Elastic Band (NEB) method is developed and tested. It is a method for finding reaction paths and TS, which can be used to theoretically compute reaction ... -
Sums with hyperbolic conditions
(2025-12-18)We develop a generalization of the hyperbola method, a technique used to obtain asymptotic estimates for summations involving a product of variables as a constraint, given that similar sums over rectangular regions can be ... -
Language Modeling and Understanding Through Paraphrase Generation and Detection
(2025-12-18)Language enables humans to share knowledge, reason about the world, and pass on strategies for survival and innovation across generations. At the heart of this process is not just the ability to communicate but also the ... -
Epitaxy of 2D Materials on Gallium Nitride
(2025-12-17)In this thesis, the epitaxial growth of 2H-TaS$_2$ few layers onto GaN(0001) is demonstrated. A growth study is presented, in which the influence of substrate temperature and reactant fluxes is investigated via electron ... -
Responses of timber species to climatic changes in Northern Germany: Studies on the radial stem growth and the fine root system of European beech, Sessile oak, Scots pine and Douglas fir along a gradient of increasing aridity
(2025-12-17)Climate change with rapid warming and increasing atmospheric and edaphic drought exposes trees and forests to growing stress. Most of Central Europe’s economically important tree species have suffered vitality losses, ... -
Impacts of warmer temperatures on the above- and belowground system of four economically important timber species
(2025-12-17)Recent decades of climate warming, along with more frequent heatwaves, have profoundly affected European forests, causing vitality loss and increased mortality in many tree species. Given the essential role forests ... -
Photochemical Dinitrogen Activation and Functionalization
(2025-12-17)Photochemistry has emerged as a powerful tool for enabling challenging chemical transformations. In this thesis, light-driven strategies are explored for the conversion of dinitrogen into nitrogenous products beyond ... -
Multifunctional composites based on cellulose nanocrystals
(2025-12-17)Cellulose nanocrystals (CNCs) have garnered attention due to their distinctive features, such as high crystallinity, exceptional mechanical strength, nanoscale dimensions, extensive specific surface area, tunable surface ... -
Selectivity Control in Ruthenium- and Cobalt-Catalysed C–H Activation of Pharmaceuticals
(2025-12-17)The construction of C–C bonds is of great significance because C–C bonds are the fundamental linkages and the backbones of pharmaceuticals, agrochemicals, natural products and various materials. Consequently, the chemistry ... -
Regulation of the telomerase
(2025-12-16)Transcription is essential to transfer genetic information and to allow cell viability. Cells must control the resulting traffic of RNA polymerases (RNAP) by holding transcription into gene boundaries and prevent conflicts ... -
A journey toward independence in young mandrills ("Mandrillus sphinx"): the intertwined effects of early life adversity and maternal investment
(2025-12-15)Early life adversity (‘ELA’) can have lasting effects on development influencing both survival and physical growth in wild animal populations, with maternal care playing a crucial role in shaping these trajectories and ... -
Functional Reconstitution of SLC18 Family Transporters
