Probing quark mass effects in low-energy hadron physics
(2012-12-21)
Since quarks are confined inside hadrons, their properties as well as their contributions to hadronic observables can be assessed by indirect methods only. As the strength of the strong interaction increases with the spatial ...
CNP-expressing progenitors display strikingly differential oligodendroglial or multipotent fates, as assessed by two Cre reporter lines
(2012-12-21)
In this study, I employ a mouse line in which Cre is knocked-in for the 2’,3’ -cyclic nucleotide 3’ –phosphodiesterase (CNP) gene and compare the fates of CNP-Cre ex-pressing OPCs between two Cre reporters: Z/EG and ...
Einfluss eines hypoxischen Sauerstoffgehaltes auf entwicklungsbiologisch relevante Signalwege in humanen embryonalen Stammzellen und deren differenzierten Derivate
(2012-11-06)
Im Rahmen dieser Dissertation wurden erstmals ausführlich die verschiedenen Effekte einer Kultivierung von hES Zellen und unterschiedlichen Differenzierungsstadien unter einem physiologisch, niedrigem Sauerstoffgehalt ...
Implementation of a kinematic fit of single top-quark production in association with a W boson and its application in a neural-network-based analysis in ATLAS
(2012-09-05)
In order to provide discrimination between the Wt-channel signal and its backgrounds for analyses that try to measure single top-quark production in the Wt-channel, a kinematic fit to the lepton+jets decay ...
Phylogeny of Echiura (Annelida, Polychaeta) inferred from morphological and molecular data-implications for character evolution
(2012-09-14)
Contrary to echiuran monophyly, which is unambiguously supported by several autapomorphies, echiuran phylogenetic intra-relationships are still unknown to date. In order to contribute to a clarification this thesis ...
Supersymmetry Phenomenology in the Context of Neutrino Physics and the Large Hadron Collider LHC
(2012-09-17)
Experimentally, it is well established that the Standard Model of particle physics requires an extension to accommodate the neutrino oscillation data, which indicates that at least two neutrinos are massive and that two ...
Finite Element Methods for Geometric Problems
(2012-10-12)
In the herewith presented work we numerically treat geometric partial differential equations using finite element methods. Problems of this type appear in many applications from physics, biology and engineering use.

Adaptive numerical simulation of contact problems: Resolving local effects at the contact boundary in space and time
(2012-10-24)
This thesis is concerned with the space discretization of static and the space and time discretization of dynamic contact problems. In particular, we derive a new efficient and reliable residual-type a posteriori error ...
Eine neue fluoreszenzbasierte Methode zur Detektion von Antikörperdimeren in aus Antikörpermonomeren bestehenden Proben
(2012-10-12)
Antikörper haben die Eigenschaft, mit der Zeit zu aggregieren, was zu einem Aktivitätsverlust und einer immunologischen Reaktion beim Patienten führen kann. Steuerbare Faktoren, die eine Aggregatbildung wesentlich beeinflussen, ......
Heterotic Particle Models from various Perspectives
(2012-10-24)
We consider the compactification of heterotic string theory on toroidal orbifolds and their resolutions. In the framework of gauged linear sigma models we develop realizations of such spaces, allowing to continously vary ...
