Analysis of the regulatory function of amino acids on metabolic targets and serotonin production in Drosophila melanogaster
(2016-08-09)
Amino acid sensing mediates metabolic and behavioural adjustments in response to organismal needs. Several pathways are believed to be involved in amino acid sensing, including the TOR (Target of Rapamycin) pathway. However, ......
Symmetric products, subgroup lattices and filtrations of global K-theory
(2016-07-21)
This thesis consists of two projects in equivariant stable homotopy theory. In the first we study the rational homotopy groups of symmetric products of the G-sphere spectrum and show that they are naturally isomorphic to ...
Dispersive analysis of charmed meson decays
(2016-08-09)
The Standard Model comprises most of today's knowledge of particle physics and is overall well tested and understood. However the dynamics of strong interactions, given by Quantum Chromodynamics (QCD), are still a challenge ...
Saliency Methods for Object Discovery Based on Image and Depth Segmentation
(2016-07-26)
Object discovery is a recent paradigm in computer and robotic vision where the process of interpreting an image starts by proposing a set of candidate regions that potentially correspond to objects; these candidates can ...
The numerical simulation of a three dimensional fluid sediment system on arbitrarily shaped domains
(2016-07-26)
Current driven sediment processes and their impact on the fluid system and on the morphology is of large interest in environmental as well as in engineering sciences. In this thesis both aspects are regarded. In detail, ...
On the relation between K- and L-theory of complex C*-Algebras
(2016-07-26)
We study the space of natural transformations from connective topological K-theory to algebraic L-theory viewed as functors from C*-algebras to spectra. We prove the existence of a transformation which witnesses the ...
Theoretical Modeling of Vibrational Spectra in the Liquid Phase
(2016-05-10)
In this thesis, the theoretical modeling of vibrational spectra in the liquid phase by ab initio molecular dynamics simulations is discussed. All presented algorithms are implemented in the open-source trajectory analysis ...
Expression und Funktion des Arylhydrocarbon Rezeptor Repressors (AhRR) im darmassoziierten Immunsystem
(2016-06-24)
Der Arylhydrocarbon Rezeptor (AhR) ist ein ligandeninduzierter Transkriptionsfaktor, der als Rezeptor für Dioxin beschrieben wurde, aber auch endogene Liganden, sowie Pflanzeninhaltsstoffe aus der Nahrung binden kann. Es ...
Lichtinduzierte Primärprozesse des stabilen Radikals 1,3,5-Triphenylverdazyl
(2016-06-07)
Zum Verständnis eines jeden chemischen oder biochemischen Prozesses sind detaillierte Informationen über die Kinetik intra- und intermolekularer Energieumverteilung unverzichtbar. In der kondensierten Phase spielen ...
Re-Os geochronology of base metal sulfides from cratonic mantle xenoliths: Case study from Somerset Island (Canada) and method development
(2016-10-28)
Robust and reliable time constraints are necessary to infer the formation and evolution of the cratonic mantle. Due to the large fractionation of Re from Os during mantle melting, the Re-Os decay system has been largely ...
