Dynamics of active condensation
(2025-06-12)Active matter represents a unique class of out-of-equilibrium systems, that are ubiquitous in our everyday life. Active particles convert energy into mechanical motion and this leads to collective self-organization into ... -
Nuclear Resonances in X-ray Waveguides
(2025-06-12)Hard X-rays generally only interact very weakly with matter, so that tissue, for example, is quite transparent to them. However, this makes the controlled manipulation of X-ray light particularly challenging. While many ... -
Investigation of cytoplasmic long noncoding RNA in Saccharomyces cerevisiae
(2025-06-12)Research on lncRNAs has increased in the past, but little is known about their function. Recently, discoveries have given us insight into sense- and asRNA regulation in yeast. dsRNA is formed in the nucleus and shuttles ... -
Nanoscale optoelectronic characterization of graphene-based heterostructures
(2025-06-11)The ongoing downscaling of electronic devices requires innovative approaches to probe and manipulate electronic behavior at the nanoscale. Two-dimensional (2D) materials offer a remarkable opportunity to directly explore ... -
Winter Hardiness and Freezing Tolerance of Winter Faba Bean (Vicia faba L.): From QTL Identification and Validation to Genome-Wide Predictions of Genotypic Values
(2025-06-11)The growing interest in plant-based proteins and a more sustainable agricultural system, with wider crop rotations, reduced fertilizer input, and increased crop and fauna diversity, has intensified in response to climate ... -
C-H Bond Activation by Iridium(III) and Iridium(IV) Oxo Complexes
(2025-06-11)C−H activation by two isostructural, terminal iridium(III) and iridium(IV) oxo complexes is compared. While the driving forces for hydrogen abstraction are almost identical due to compensating contributions from H+ and e− ... -
Advancing CRISPR gene therapy for Noonan syndrome: Targeting recurrent LZTR1 variants with all-in-one Cas9 and base editors in patient-derived iPSC-cardiomyocytes
(2025-05-28)Pathogenic variants in LZTR1 are causative for Noonan syndrome with early onset of a severe hypertrophic cardiomyopathy. Despite high clinical relevance, therapeutic options are highly limited, and no curative treatment ... -
Structure and Evolution of Visual Cortical Representations
(2025-05-28)Fully understanding the functions and mechanisms of the complex machinery that is our brain requires advanced statistical data analysis and theoretical modelling. In this thesis, I develop and apply statistical tools and ... -
Transformation of waste gases into biocommodities by syngas fermentation
(2025-05-28)This study describes a total of 13 novel gas-fermenting strains from four different bacterial genera. Three strains represent a new species. These acetogenic and carboxydotrophic hydrogenogenic strains were successfully ... -
Measurement of top quark pair production in association with charm quarks at √s = 13 TeV with the ATLAS detector
(2025-05-28)The Large Hadron Collider at CERN has produced a uniquely large set of proton-proton collision data at never-before-seen energies since the beginning of its operation in 2010. Using data collected by the ATLAS detector ... -
Tau oligomers and stress granules: Molecular insights into slowly and rapidly progressive Alzheimer’s disease
(2025-05-27)Alzheimer’s disease (AD) exhibits substantial clinical and molecular heterogeneity, with rapidly progressive AD representing a distinct and aggressive subtype. This study provides an in-depth characterization of stress ... -
Painting a bigger picture on response of European beech (Fagus sylvatica L.) to climate change – past vs. status quo
(2025-05-22)Impacts of climate change on forest ecosystems are becoming more visible than ever before. Whereas the performance of European forests is of great ecological as well as of economic importance, the term “vitality” itself ... -
Dendroclimatic investigation of European beech growth dynamics along a precipitation gradient in northern Germany
(2025-05-22)This thorough study of European beech (Fagus sylvatica) growth limits in Northern Germany shows the major difficulties caused by climate change and global warming. Drawing on the findings of three main chapters, we arrive ... -
The temporal characteristics of the motion bridging effect and a connected illusion: Time-related interactions and dependencies in a two-process-model
(2025-05-22)The Motion Bridging Effect (MBE) is a visual illusion in which a motion that is not consciously visible, due to high speed, induces an illusory rotation percept in a stationary stimulus (test ring) that is presented ... -
Connecting the Dots: Dust Particle Tracking at Comet 67P/Churyumov-Gerasimenko
(2025-05-21)Comets and their characteristic plasma and dust tails have been intriguing people for millennia. Early theories about their nature were for example already developed by the ancient Chinese and Greek, but it was not until ... -
Preorganization within a pyrazolato-bridged bis-β-diketiminato dinickel frame as a key tool to access terminal sulfides and synergistically stabilized intermediates for acetyl-CoA synthase mimetic thioester formation
(2025-05-21)Bimetallic complexes are frequently employed in natural enzymes and in applications such as imaging, targeting, and catalysis, in order to exploit the synergy between two metal centers or to combine different functionali ... -
Effects of environmental change on grassland birds in the Central-Asian flyway through the annual cycle
(2025-05-20)Land use change is a significant driver of biodiversity loss, but its impacts have been largely studied with a particular focus on temperate regions and forest ecosystems. In this thesis, I used bird abundance, occurrence, ... -
Investigation of Nuclear Hyperfine Coupling in H2 Heterodimers Using Rotational Spectroscopy
(2025-05-20)Rotational spectroscopy of gas phase compounds is a powerful technique for structure determination through the unique moments of inertia of a molecular system. It is sensitive angular momentum coupling; therefore, complicated ... -
