Coherently driven three-level atoms in an optical cavity
(2012-02-17)
We experimentally realize strong light-matter coupling of a single cesium atom to a single mode of a high-finesse optical cavity. In this regime, the optical properties of one atom change the transmission spectrum of the ...
The role of Four-and-a-half LIM domain protein 2 in dendritic cell migration
(2012-01-12)
We identified the four-and-a-half LIM domain protein 2 (FHL2) as a novel regulator of CCL19-induced dendritic cell (DC) migration. Initiation of migration is a hallmark of DC function and plays a central role in the induction ......
Rolle der Aktivierung des Peroxisome proliferator-activated receptor gamma durch Pioglitazon in der hepatischen Immunregulation
(2012-02-17)
Der Peroxisome proliferator-activated receptor gamma (PPARγ) gehört zur Superfamilie nukleärer Faktoren, die nach Ligandenbindung Genexpression regulieren. PPARγ steuert durch Bindung an PPARγ-responsive Elemente die ......
Peroxisome proliferator-activated receptor gamma (PPARγ) belongs to the superfamily of nuclear receptors regulating gene expression upon ligand binding. After binding to responsive elements PPARγ induces the expression of ......

Determination of the η mass from the production threshold for the γp → pη reaction
(2012-01-30)
This thesis is dedicated to a new precise determination of the η meson mass based on a measurement of the threshold for the γp → pη reaction. This experiment was performed in the years 2004/2005 using the Crystal Ball/TAPS ...
Control of photochromic molecules adsorbed to optical microfibres
(2012-02-17)
The high light intensity in an optical microfibre and the resulting nonlinear effects were applied to develop a new method to precisely determine the microfibre diameter. The evanescent field of these optical microfibres ...
Perfectoid spaces
(2012-03-09)
We introduce a certain class of so-called perfectoid rings and spaces, which give a natural framework for Faltings' almost purity theorem, and for which there is a natural tilting operation which exchanges characteristic ......
Das Kolosseum in der Druckgraphik des 15. bis 19. Jahrhunderts
(2012-06-08)
Als einstige Hauptstadt eines antiken Imperiums und Machtzentrum einer Weltreligion bot Rom kontinuierlich Anlass zur Auseinandersetzung mit seiner Vergangenheit und Gegenwart. Die Beschäftigung mit der „Ewigen Stadt“ in ...
Four Essays in Empirical Finance
(2012-10-10)
In four self-contained essays, this thesis aims at empirically exploring phenomena which emerge as a result of the asymmetric information stemming from the separation of ownership and control. Chapter 1 deals with the ...
Fiscal News, Uncertainty, and the Business Cycle
(2012-02-08)
The recent "Great Recession" has thrown macroeconomic research into a state of disarray and has clearly shown the need to go beyond traditional business cycle explanations. However, many of the recently proposed business ...
Contracting in the Presence of Uncertainty
(2012-08-24)
This thesis concerns the enforcement of contracts in the presence of uncertainty. Sometimes uncertainty is exogenously given and the agents cannot influence its existence. Frequently, however, there is strategic uncertainty ...
