Three-Body Hadron Dynamics from Lattice QCD: A Non-Relativistic Effective Field Theory Approach
(2024-09-16)Presently, lattice quantum chromodynamics is the only available tool that allows for the calculation of hadron properties in terms of their constituents, quarks and gluons, incorporating the non-perturbative nature of the ... -
Stereoconvergent, Intramolecular Transfer Reactions to β-Titanoxy Radicals
(2024-09-16)This thesis describes a number of reactions that exploit intramolecular, radical group transfer to β-titanoxy radicals. It is mostly aimed at advancing the field of titanium-catalyzed epoxide hydrosilylation reactions, ... -
Global homotopy theory via partially lax limits
(2024-09-16)Global equivariant homotopy theory is often motivated as the study of compatible collections of equivariant objects for some family of compact Lie groups. In this thesis we make this heuristic precise, by exhibiting the ... -
Entwicklung kooperativer Ti/Cr-Systeme zur Umprogrammierung von Borhydriden als Elektron- und H-Atom-Transferreagenzien
(2024-09-12)Das in dieser Arbeit vorgestellte kooperative Katalysesystem vereint eindrucksvoll die Vorteile Ti<sup>III</sup>-katalysierter Epoxidöffnungen mit denen des CpCr(CO)<sub>3</sub>H-vermittelten H-Atom-Transfers. Dadurch wird ... -
q-Series, their Modularity, and Nahm's Conjecture
(2024-09-11)This thesis concerns modularity properties of Nahm sums, a family of <em>q</em>-hypergeometric series, and applications. They appear, for example, as characters of VOAs, knot invariants, and generating functions for classes ... -
Studies for current and future high-intensity operation of CERN's secondary M2 beamline
(2024-09-10)The AMBER experiment is aiming at studying the fundamental QCD processes generating the hadronic degrees of freedom by measuring the excitation spectra of strange mesons, as well as the valence and sea quark, and gluon ... -
Synthese C2-symmetrischer chiraler Bis(boronsäuren) und ihre Anwendung in der Darstellung von chiralen kovalenten organischen Käfigen
(2024-09-10)Diese Arbeit behandelt die Synthese und Charakterisierung kovalent organischer Käfige basierend auf chiralen Boronsäureestern. Sie kann grob in zwei Abschnitte unterteilt werden: Synthese von chiralen C<sub>2</sub>-symmetrischen ... -
Phenotypic and transcriptional characterization of myeloid cells in high grade serous ovarian carcinoma
(2024-09-05)Mononuclear cells are a very heterogeneous population of immune cells, with monocytes and macrophages showing high plasticity in response to different environmental signals. Moreover, dendritic cells subsets appear in ... -
Audio Embeddings for Semi-Supervised Anomalous Sound Detection
(2024-09-03)Detecting anomalous sounds is a difficult task: First, audio data is very high-dimensional and anomalous signal components are relatively subtle in relation to the entire acoustic scene. Furthermore, normal and anomalous ... -
Interfaces in Metal-Oxygen Batteries: Adsorbate formation and influence on oxygen reduction
(2024-09-09)This study deals to a large extent with the formation of adsorbates during the oxygen reduction reaction in organic electrolytes on gold and platinum surfaces. The mainly used methods are voltammetry (also at rotating ring ... -
Poplars, apoplastic barriers, and the environment
(2024-09-02)This doctoral thesis, “Poplars, apoplastic barriers, and the environment”, is dedicated to the ecophysiological traits of poplars, especially their apoplastic barriers in roots and leaves, in the scope of environmental ... -
The bidirectional link between visual processing and optomotor flight behavior in Drosophila
(2024-09-02)Animals that explore the world need to reliably move in a preplanned direction. With the optomotor response, flies stabilize a straight path during flight by visual feedback. Unintended deviations from a straight path are ... -
Operator based multi-scale analysis of simulation bundles
(2015-11)We propose a new mathematical data analysis approach, which is based on the mathematical principle of symmetry, for the post-processing of bundles of finite element data from computer-aided engineering. Since all those ... -
Suboptimal feedback control of PDEs by solving HJB equations on adaptive sparse grids
(2015)An approach to solve finite time horizon suboptimal feedback control problems for partial differential equations is proposed by solving dynamic programming equations on adaptive sparse grids. A semi-discrete optimal control ... -
Search for single production of vector-like quarks decaying into a Wb final state at √s = 13 TeV with the ATLAS detector
(2024-08-28)In this thesis, a search for single-production of vector-like quarks was performed using data collected during Run 2 of the Large Hadron Collider (LHC) by the ATLAS detector. The primary focus of this thesis was on the ... -
Sparse grids for the Schrödinger equation
(2005-12)We present a sparse grid/hyperbolic cross discretization for many-particle problems. It involves the tensor product of a one-particle multilevel basis. Subsequent truncation of the associated series expansion then results ... -
Molecular dynamics simulations of the influence of chemical cross-links on the elastic moduli of polymer-carbon nanotube composites
(2005-06)In this article we compare the Young modulus of polyethylene carbon nanotube composites with chemical cross-links between the nanotube and the polyethylene matrix to the modulus of a composite with weak non-bonded ... -
Multiscale simulation of polymeric fluids using the sparse grid combination technique
(2017-10)We present a computationally efficient sparse grid approach to allow for multiscale simulations of non-Newtonian polymeric fluids. Multiscale approaches for polymeric fluids often involve model equations of high dimensionality. ... -
A wavelet based sparse grid method for the electronic Schrödinger equation
(2006-05)We present a direct discretization of the electronic Schrödinger equation. It is based on one-dimensional Meyer wavelets from which we build an anisotropic multiresolution analysis for general particle spaces by a tensor ...
