Novel Small Molecule Inhibitors Dissecting GEF-dependent and -independent Cytohesin Functions in Immune Cell Signaling
Novak, Nina Maria (2014-06-20)Cytohesins are guanine nucleotide exchange factors (GEFs) for the small GTPases of the ARF family. They play important roles in immune cell signaling, immune cell adhesion and migration and furthermore in non-immune insulin ... -
Novel vaccination strategies for CD4+ T cell immunotherapy of melanoma
Shridhar, Naveen (2019-09-06)Immunotherapy has emerged as a standard treatment modality in melanoma and many other cancers. While a lot is known about the anti-tumoral effector functions of CD8+ T cells, CD4+ T cells remain less well understood in ... -
Nuclear export of single native mRNA molecules observed via light sheet fluorescence microscopy and transcriptional regulation of BR2.1 during heat-shock
Kaminski, Tim Patrick (2015-01-06)Eucaryotes store most of their genetic information in the nucleus. Parts of this information encode the amino acid sequence of proteins. To synthesize a protein according to the nucleotide sequence, first the corresponding ... -
Nuclear Lattice Investigations of Fundamental Symmetries
Körber, Christopher (2018-04-10)Fundamental symmetries (and their violations) play a significant role in active experimental searches of Beyond the Standard Model (BSM) signatures. An example of such phenomena is the neutron Electric Dipole Moment (EDM), ... -
Nuclear Physics in a finite volume: Investigation of two-particle and α-cluster systems
Stellin, Gianluca (2021-01-25)We investigate both analytically and numerically some artifacts introduced by the lattice environment in two-body charged fermion and antifermion systems and in α-conjugate nuclei. The finite (hyper)cubic lattice as a ... -
Nuclear Structure of Light Ca and Heavy Cr Isotopes
Bürger, Alexander (2007)Although the nuclear shell model was conceived almost 60 years ago, and despite the continuous efforts in experimental and theoretical nuclear physics research, the prediction of nuclear properties is still a challenging ... -
Nucleon-nucleon scattering process in Lattice Chiral Effective Field Theory approach up to next-to-next-to-next-to-leading order
Du, Dechuan (2018-04-23)We carry out a comprehensive analysis of the neutron-proton interaction up to the third order in the scheme of chiral effective field theory on the lattice. The complete two-pion exchange potential is taken into account ... -
Numerical Approximation of Optimal Microstructures in Elastic Shape Optimization
Geihe, Benedict (2023-06-15)We develop and analyze a numerical two-scale optimization scheme for structural shape optimization. Whenever cost functionals, such as the elastic energy, are subject to minimization, while meeting a constraint on the ... -
Numerical calculation of automorphic functions for finite index subgroups of triangle groups
Krämer, Stefan (2015-08-20)We present a new method to calculate automorphic functions for finite index subgroups of triangle groups. Since automorphic functions are holomorphic, it is well known that the real and the imaginary part are both harmonic. ... -
Numerical investigations of heat and mass transport in fractured porous rock masses
Hamidi, Sahar (2019-01-08)Fluid flow processes in the subsurface are accompanied by heat and mass transport with several important feedbacks including reactive flow, and precipitation/dissolution processes. Heat and mass transport through fractured ... -
Numerical Methods for a Reduced Model in Thin-Film Micromagnetics
Drwenski, Jörg (2008)We address the conformal finite element approximation to a reduced 2-d model arising in thin-film micromagnetics. The model was derived by DeSimone, Kohn, Müller, and Otto for a thin-film ferromagnetic element under an ...

Numerical Methods for Optimal Transport and Elastic Shape Optimization
Simon, Stefan (2019-12-06)In this thesis, we consider a novel unbalanced optimal transport model incorporating singular sources, we develop a numerical computation scheme for an optimal transport distance on graphs, we propose a simultaneous elastic ... -
Numerical Methods for Uncertainty Quantification in Gas Network Simulation
Fuchs, Barbara (2018-09-26)When modeling the gas flow through a network, some elements such as pressure control valves can cause kinks in the solution. In this thesis we modify the method of simplex stochastic collocation such that it is applicable ... -
Numerical Methods in Shape Spaces and Optimal Branching Patterns
Heeren, Behrend (2017-04-25)The contribution of this thesis is twofold. The main part deals with numerical methods in the context of shape space analysis, where the shape space at hand is considered as a Riemannian manifold. In ... -
Numerical methods in stochastic and two-scale shape optimization
Tölkes, Sascha (2018-04-26)In this thesis, three different models of elastic shape optimization are described. All models use phase fields to describe the elastic shapes and regularize the interface length on some level or scale to control fine-scale ... -
Numerical modeling of electromagnetic coupling effects for phase correction in borehole EIT measurements
Zhao, Yulong (2017-04-25)Spectral Electrical Impedance Tomography (EIT) allows obtaining images of the complex electrical conductivity for a broad frequency range (mHz to kHz). It has recently received increased interest in the field of near-surface ... -
