Ultrastrukturelle Analyse sowie Steuerung der Substratadhäsion kardialer Zellen
(2012-06-04)
Fokaladhäsionen symbolisieren nicht nur einfache starre Verankerungspunkte der Zelle an das extrazelluläre Substrat, sondern sie stellen hochdynamische Multiproteinaggregate innerhalb der Zelle dar, die je nach Anforderung ...
Single impurity atoms immersed in an ultracold gas
(2012-06-20)
In this thesis, experiments with an ultracold gas doped with few and single atoms of another species are presented.
The techniques to adequately prepare and manipulate an ultracold Rb gas and to dope it with a precisely ...

Analyses of Adhesion Topography and Fluctuations in Bio-Membranes by Advanced Optical Microscopy
(2012-05-21)
The cell membrane not only mechanically separates the interior of the cell from the exterior environment but is also an active organelle involved in a host of functions like maintaining osmotic balance, aiding in ...
Measurement of the top quark pair production cross section with the ATLAS detector at LHC in pp collisions at √s =7 TeV in dilepton final states
(2012-06-04)
The production cross section of top quark pairs in proton-proton collisions at center-of-mass energy of 7 TeV recorded with the ATLAS detector at the CERN Large Hadron Collider is measured. The goal of the analysis is to ...
Lichtinduzierter Ladungstransport in undotierten Lithiumniobat-Kristallen
(2012-06-14)
Die Kombination von optischer Nichtlinearität und der Möglichkeit zur ferroelektrischen Domänenstrukturierung machen Lithiumniobat-Kristalle zu einem der wichtigsten Materialien im Bereich optischer Technologien. Unerwünschte ...
Measurement of beauty production in deep inelastic scattering at HERA using decays into electrons
(2011-03-29)
The production of beauty quarks in $ep$ interactions has been studied with the ZEUS detector at HERA for exchanged four-momentum squared $Q^{2} > 10 GeV^{2}$, using an integrated luminosity of $363 pb^{-1}$. The beauty ...
Phasengenaue Impedanzspektroskopie und -tomographie für geophysikalische Anwendungen
(2011-03-22)
Die elektrische Impedanzspektroskopie und die spektrale elektrische Impedanztomographie sind leistungsfähige Methoden zur nichtinvasiven Charakterisierung von Materialien bezüglich ihrer strukturellen Eigenschaften. Bei ...
Isotopes for fundamental research 83mKr for KATRIN and 101Rh and 109Cd for XRD studies on planets
(2011-03-15)
The feasibility of production of 83Rb from liquid, natural Br at the Bonn Cyclotron was shown. Production of 83Rb/83mKr generators for KATRIN Collaboration was optimized. 83mKr ...
Embedding the DFSZ–Axino in mSUGRA with R–Parity Violation and its implications for Dark Matter
(2011-01-21)
We embed the DFSZ axion in supersymmetry with broken R–parity. As Supersymmetry provides hundreds of free parameters we restrict ourselves to the lepton–number violating scenario in minimal supergravity models with ...
Information-theoretic approach for the characterization of interactions in nonlinear dynamical systems
(2011-05-11)
Symbolic time series analysis provides us a solid and broadly used toolkit for the characterization of interactions between nonlinear dynamical systems. In this thesis, information-theoretic measures are evaluated with ...
