Measurement of the γn→K0Σ0 photoproduction at the BGOOD experiment and the relation to possible pentaquark states
(2022-04-08)
Hadrons are particles consisting of quarks bound by the strong force. Ground states and lower lying
excitations can be described successfully as mesons consisting of quark-antiquark pairs and baryons
consisting of three ......
Klinische und ökonomische Aspekte einer verzögerten Revisionschirurgie im Bereich der zementfreien Hüftwechselprothetik: Eine retrospektive Studie an 53 Fällen der Wechselprothetik einer künstlichen Hüftpfanne mit 3D-Titannetzbeschichtung
(2022-01-17)
Einleitung: Die langzeitbeständigen zementfreien Pfannen- und Schaftimplantate mit osteologisch hochwertigen Beschichtungen sind nach wie vor gefährdet durch Abrieb der Gleitpaarung mit den periprothetischen ...
Networks, translocality, and the resilience of rural livelihoods in Northeast Thailand: Insights from a social network perspective
(2022-03-24)
This dissertation aims to substantiate the ongoing debate on migration and its role in resilience building, and in particular in building resilient rural livelihoods amidst rural transformation and climate change. For a ...
A variational approach to Gibbs measures on function spaces
(2022-03-18)
We study develop a variational technique to study models from constructive quantum field theory. Our starting point is the interpretation of the Polchinski equation as the Hamilton-Jacobi-Bellman equation of a stochastic ...
Impacts of the expansion of aquaculture on global agricultural markets and land use change
(2022-02-14)
Aquaculture is one of the most rapidly growing food producing sectors. It has the potential to meet future seafood demand from a growing global population. However, the expansion of aquaculture has led to a continuous ...
Veränderungen im Belohnungssystem bei Depression: Effekte der Tiefen Hirnstimulation des medialen Vorderhirnbündels
(2022-02-07)
Die vorliegende Arbeit zeigt im Rahmen einer explorativen Pilotstudie Veränderungen verschiedener Belohnungsprozesse im Rahmen der Tiefen Hirnstimulation (THS) des medialen Vorderhirnbündels bei therapieresistenter Depression ...
Vertex Deletion Problems: A Parameterized Point of View
(2022-02-25)
In this thesis we study various vertex deletion problems. In a vertex deletion problem, we are given a graph G and an integer k, and want to delete at most k vertices from G such that the resulting graph belongs to a certain ...
The Role of Job Changes in Sustainable Return to Work for Breast Cancer Survivors – Patterns of Interpretation and Coping Strategies
(2022-01-06)
Thus far, research on return to work (RTW) after breast cancer has focused on objective outcomes such as return rates. Moreover, a strong emphasis on the initial RTW can be observed in the literature. However, knowledge ...
