Receptor-mediated activation and pharmacological inhibition of heterotrimeric G proteins
(2022-11-14)
Heterotrimeric guanine-nucleotide binding proteins (G proteins) are key signal transducers in animal and human cells, where they forward signals transmitted by active G protein-coupled receptors (GPCRs) and trigger ...
Measuring Excitations of a Strongly Interacting Superfluid Fermi Gas
(2022-11-24)
This thesis investigates experimentally the superfluid phase of strongly interacting ultracold Fermi gases. The diluteness of the considered gases of neutral atoms ensures that their interaction can be described by a single ...
Gain Calibration of the Upgraded ALICE TPC
(2022-11-24)
For the upcoming Run 3 of the LHC at CERN, the interaction rate of lead-lead collisions will be increased to 50kHz . Especially for the main detector of the ALICE experiment, the TPC, this is a major challenge, as its ...
Untersuchung der mechanobiologisch gesteuerten Brustkrebszellinvasion mittels 3D Zellkulturmodellen
(2022-12-20)
Ein erster zentraler Schritt während der Metastasierung bei Brustkrebs ist die lokale Zerstörung der Basalmembran (BM), gefolgt von der Transmigration invasiver Zellen. Dieser Prozess ist in vivo schwierig zu visualisieren, ...
Novel aspects regarding structural variability in membrane protein families by the example of tetraspanins
(2022-11-16)
The work at hand focuses on structural variability in membrane protein families by the example of tetraspanins. The family of tetraspanins is found in almost all multicellular organisms and they play important roles in an ...
On a non-local free boundary problem modeling cell polarization
(2022-11-08)
The amplification of an external signal is a key step in direction sensing of biological cells, a process that contributes significantly in the regulation of cell shape. This thesis is concerned with a simple model for ...
Sheaves, Quasimaps, Maps, Covers
(2022-11-09)
Let $X$ be a smooth variety, let $S$ be a smooth surface, let $C_{g,N} rightarrow overline{M}_{g,N}$ be a universal curve over a moduli space of stable marked curves and let $(C,mathbf{x})$ be a marked nodal curve.
Analysis of Elliptic and Parabolic Partial Differential Equations Based on Carleson Measures
(2022-09-02)
This thesis proposes a new technique to analyze nonlinear elliptic and parabolic partial differential equations by exploiting the knowledge generated by the associated Carleson measure characterization of admissible data ...
Molecular diversity in early stage high-mass protostars
(2022-11-30)
During star formation, the molecular gas undergoes significant chemical evolution with the emergence of dense cores harboring hot cores and hot corinos, rich in complex organic molecules (COMs). The formation pathways, ...
Unraveling Molecular Gas Conditions across Nearby Galaxies with CO Isotopologues
(2022-12-07)
In general, we associate large spatial scales, heavy massive objects, and great distances with the scientific study of Astronomy. However, in this thesis, we study the tiny hydrogen molecule, H2, which populates ......
