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 ...

(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.
Neurochirurgische Auswertung der postoperativen Komplikationen chirurgischer Eingriffe bei pinealen Germinomen (Resektion versus Biopsie) der SIOP CNS GCT 96 Studie
(2022-11-16)
Einleitung: Germinome zeigen sich als hochsensibele Tumore gegenüber Radio- und Chemotherapie. Allerdings sind Germinome in der Regel Marker-negativ, sodass die Diagnose ausschließlich chirurgisch durch ...
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 ...
Effect of cannabidiol on cytokine-induced killer cells in multiple myeloma and pancreatic cancer
(2022-09-06)
Background/Aim: Cytokine-induced killer cells (CIKs) are a heterogeneous population of polyclonal T lymphocytes showing a potent anti-tumor activity. Cannabinoids have been recently used for the treatment of cancer. In ......
Prader-Willi-Syndrom - Früher Beginn der Wachstumshormontherapie und Auswirkungen auf Metabolik und Auxologie
(2022-09-07)
Hintergrund: Das Prader-Willi-Syndrom (PWS) ist eine genetische Multisystemerkrankung, die durch eine Dysfunktion der Hypothalamus-Hypophysen-Achse gekennzeichnet ist. Neuere Forschungsergebnisse empfehlen ...
