Can the halo model describe 2nd- and 3rd-order correlation functions of gravitational lensing consistently?
(2019-11-07)
To understand and model the distribution of and the relation between baryonic and dark matter in the Universe is one of the key challenges in contemporary astrophysics. A well-established theoretical description is given ......
Establishment of anti-apoptotic brakes in human neurons during maturation
(2019-11-29)
Neurons represent a highly specialised cell population of the central and peripheral nervous system, which is responsible for spreading information throughout the body. They are born during embryonic development and persist ...
Constraint-based automated reconstruction of grape bunches from 3D range data for high-throughput phenotyping
(2019-10-25)
With increasing global population, the resources for agriculture required to feed the growing number of people are becoming scarce. Estimates expect that by 2050, 60 % more food will be necessary. Nowadays, 70 % of fresh ...
Moduli spaces of K3 surfaces and cubic fourfolds
(2019-11-14)
This thesis is concerned with the Hodge-theoretic relation between polarized K3 surfaces of degree d and special cubic fourfolds of discriminant d, as introduced by Hassett.
For half of the d, K3 surfaces associated ......

Casson-Whitney unknotting, Deep slice knots and Group trisections of knotted surface type
(2022-08-26)
In this thesis, we study knotted surfaces in 4-dimensional manifolds from three different but interconnected perspectives.
In the first part, we introduce a measure of 'distance', or rather 'length', between ...

Die Aufklärung eines neuartigen Pentose-Stoffwechsels und die Möglichkeit einer Homosuccinat-Fermentation in Darmbakterien
(2022-08-26)
In der vorliegenden Arbeit wurde der Pentose-Metabolismus des bedeutsamen Darmbakteriums Prevotella copri (P. copri) untersucht, und es wurde analysiert, ob die Umsetzung einer Homosuccinat-Fermentation mit dem Darmbakterium ......
Torsion classes, wide subcategories and maximal green sequences
(2022-08-26)
In this thesis, the relationship between torsion classes and wide subcategories in module categories of finite dimensional algebras is studied. Of particular interest are wide intervals, which are interval subsets of the ...
Annelid chaetae: Ultrastructure, arrangement and phylogenetic significance
(2022-08-26)
With approximately 21,000 described species, Annelida represent one of the largest and best studied group of marine invertebrates. Their anatomy is characterized by a metameric organization, which covers potential for an ...
Temporal Graph Algorithms
(2022-07-21)
Temporal graphs are often good models for real-life scenarios due to the inherently dynamic nature of most real-world activities and processes. A significant difference between conventional static and temporal graphs is ......
Parametric excitation of the quantum vacuum in nonlinear optical resonators
(2022-07-25)
In this thesis, I present the generation of correlated photon pairs in high-finesse nonlinear optical micro-resonators. In a first attempt, we utilize the third-order nonlinear material polarization of the dielectric mirror ...
