Function of RIM4 in cerebellar circuits
(2023-12-18)RIMs (Rab3-interacting molecules) are multidomain proteins, enriched at presynaptic active zones. The large isoforms (RIM1 a/ß, RIM2 a/ß) have been shown to be important for mediating presynaptic active zone function by ... -
Gas matters: The Molecular and Atomic Gas Budget in Nearby Galaxies from Centers to Outskirts
(2023-12-18)Hydrogen is the most fundamental component of the baryonic universe, and its various phases have played a key role in its evolution from the Big Bang to the present day. To probe and study these phases of hydrogen in the ... -
Dynamic Local Usage in BonnRouteGlobal
(2023-12-14)In this dissertation we consider the global routing problem which is a central task in chip design. Up to millions of sets of pins on a chip, so called nets, have to be connected through wires without intersecting each ... -
Approaching Partial Differential Equations with Physics-Driven Deep Learning
(2023-12-14)Partial Differential Equations (PDEs) play an important role in describing continuous physical systems such as fluids, air-flows, waves and many more. Thus, by solving these equations, one can simulate smoke and water ... -
Nonmetal coordination chemistry: P-adducts of electrophilic, terminal phosphinidene complexes
(2023-12-13)This PhD thesis focused on the synthesis and reactions of neutral, donor-stabilized electrophilic, terminal phosphinidene complexes bearing only π-accepting coligands starting from very strained P-heterocycle complexes or ... -
Adding New Functionalities to Optical Fiber Cavities by Direct Laser Writing
(2023-12-12)Fiber Fabry–Pérot cavities (FFPCs) are fiber-based optical cavities, which find widespread applications, for example, in cavity quantum electrodynamics, spectroscopy, sensing, metrology, and in many more fields. They provide ... -
Explainable Resource-Aware Representation Learning via Semantic Similarity
(2023-12-12)The rapid advancement of artificial intelligence (AI) systems in recent years is largely due to the impressive capabilities of artificial neural networks. Their powerful capabilities in natural language understanding and ... -
On the Numerical Computation of Modular Forms
(2023-12-12)This thesis presents a fast method for the numerical computation of modular forms. Our method significantly improves the performance of previous methods by using mixed-precision iterative solving techniques to reduce the ... -
Complement receptors 3 and 4 in kidney diseases
(2023-12-11)CR3 and CR4 are among the most abundant molecules on the cell surface of DCs, monocytes/macrophages, and PMNs. Both integrins recognize common ligands among which are iC3b, ICAM-1, and fibrinogen. iC3b is generated as a ... -
Solving all the problems of our universe, one neutrino mass model at a time
(2023-12-11)The masses and mixing in the neutrino sector can not be explained by the Standard Model (SM) of particle physics and might be a harbinger for new degrees of freedom at energies scales far above or comparable to the electroweak ... -
Advances in Quantitative Precipitation Estimation with Polarimetric C-Band Radar Networks
(2023-12-06)Areal quantitative precipitation estimation (QPE) with high spatial and temporal resolution is crucial to feed nowcasting and hydrological models. Ground-based weather radars are the best-suited tool for this purpose. ... -
Keeping in Touch: Visualising and Perturbing Photorespiratory Organelle Proximity in Plants
(2023-12-06)Organelles within cells are typically depicted as isolated structures, but increasing evidence shows that they are interconnected via specific membrane contact sites (MCS). While MCS research in mammals and yeast is gaining ... -
A dark quencher genetically encodable voltage indicator (dqGEVI) for high fidelity recordings in murine and human in vitro systems
(2023-12-04)To understand neurons and neural circuits it is necessary to visualize their electrical activity. <br /> In contrast to traditional electrophysiological techniques, optical methods are very promising as they tend to ... -
The Synaptic Basis of Binocular Alignment and its Development in Ferret Primary Visual Cortex
(2023-12-01)The brain integrates information from a myriad of external stimuli to generate a rich but consistent representation of the world and instruct behavior. For coherent binocular vision, signals from both eyes need to be ... -
Development and optimization of analytical methods for identifying and quantifying organic compounds in biological and paleontological specimens
(2023-12-01)Preservation of soft tissues is a rare phenomenon which leads to the formation of fossils that survive for millions of years and are then subject to investigations by paleontologists. Several classes of chemical compounds ... -
C and CP Violation in Light-Meson Decays
(2023-11-29)This dissertation delves into the systematic parameterization of a simultaneous violation of C and CP in the light-meson sector, i.e., a source of CP violation that has been mostly disregarded over the past six decades. ... -
Interpretable deep learning for studying the Earth system: Soil-moisture-precipitation coupling across Europe
(2023-11-23)The Earth system is a highly complex dynamical system. While considerable process understanding has been achieved in past research, many processes and relations in the Earth system remain poorly understood due to this ... -
Raumproduktion durch städtebauliche Großprojekte als Instrumente der urbanen Transformation: Eine vergleichende Studie aus Köln
(2023-11-21)Die Arbeit untersucht städtebauliche Großprojekte als einen spezifischen Modus der Stadtentwicklung im Sinne einer Produktion von Raum. Der Begriff „Raumproduktion“ geht dabei zurück auf die Theorie der Produktion des ... -
Cryo-EM structures of the human NLRP3 inflammasome
(2023-11-20)NLRP3 is an intracellular sensor protein whose activation by a broad spectrum of exogenous and endogenous stimuli leads to inflammasome formation and pyroptosis. The mechanisms leading to NLRP3 activation and the way how ... -
Exploring the Epoch of Reionization with Line-Intensity Mapping
(2023-11-20)The epoch of reionization (EoR) stands as a key phase in the history of the Universe, where the neutral elements that pervaded the cosmos gradually became ionized. This process was driven by the photons emitted by the the ...
