Optogenetische Kontrolle von cAMP durch eine photoaktivierte Adenylatzyklase
(2015-03-27)
Optogenetik ist eine Methode, bei der lichtaktivierbare Proteine zur Manipulation zellulärer Funktionen verwendet werden. Häufig genutzt werden hierbei lichtaktivierbare Ionenkanäle und -pumpen, wie beispielsweise ......
Calculating Corrections in F-Theory from Refined BPS Invariants and Backreacted Geometries
(2015-03-31)
This thesis presents various corrections to F-theory compactifications which rely on the computation of refined Bogomol'nyi-Prasad-Sommerfield (BPS) invariants and the analysis of backreacted geometries.

Evidence for the Higgs Boson Decay to t+t- in the Lepton + Hadrons Final State with ATLAS
(2015-03-12)
The data recorded with the ATLAS experiment during the first run period of the Large Hadron Collider are analysed by selecting final states with two τ-leptons, which further decay to a lighter lepton and to hadrons, ...
Cluster analysis of European surface ozone observations for evaluation of MACC reanalysis data
(2015-04-22)
The high density of European surface ozone monitoring sites offers good opportunities for investigation of the regional ozone representativeness and for evaluation of chemistry climate models. In this thesis we analyze ...
Untersuchung der Primzahlzählfunktion und verwandter Funktionen
(2015-04-22)
Die Verteilung der Primzahlen ist bekanntlich eng mit den Nullstellen der Riemannschen Zetafunktion verbunden. Insbesondere hat die Riemannsche Vermutung, nach welcher alle nichttrivialen Nullstellen den Realteil 1/2 ...
Rearranged DNA in mitochondrial DNA maintenance disorders
(2015-03-31)
Mitochondrial genetics has been changing its focus during the last decade. Originally limited to describing effects of mutations of the mitochondrial DNA (mtDNA) research at present aims to understand circumstances of ...
O-GlcNAc – a posttranslational modification implicated in Alzheimer disease?
(2015-04-22)
O-linked N-acetylglucosamine (O-GlcNAc) is a highly dynamic posttranslational modification which has been found on a myriad of nucleocytoplasmic proteins. O-GlcNAc addition and removal are catalyzed by two conserved enzymes, ......
Counting classes of special polynomials
(2015-04-20)
Most integers are composite and most univariate polynomials over a finite field are reducible. The Prime Number Theorem and a classical result of Gauß count the remaining ones, approximately and exactly.

Suberin biosynthesis in O. sativa: characterisation of a cytochrome P450 monooxygenase
(2015-03-20)
In endodermal and exodermal cell walls of roots the polyester suberin forms a radial diffusion barrier for water, solutes and gases. Depolymerization of this otherwise insoluble lipophilic polymer releases its aliphatic ...
Dnajc22 - a new susceptibility gene for salt-sensitive hypertension
(2015-06-10)
Chaperones of the heat shock (HSP) 70 family mediate elementary funtions in a cell, such as folding, oligomerization, transport, or degradation of proteins. Their function is particularly needed when cells are exposed to ...
