Two-pion exchange contributions for coupled-channel B(*)B(*) and B(*) B(*) scattering
Chacko, Jabez Tom (2024-07-26)In the paper [Phys.Rev.D 99 (2019) 9, 094013] of V. Baru et al., the LO and incomplete NLO potentials were utilised to investigate the line shapes of Zb(10610) and Zb(10650) and their (yet to be discovered) spin partners. ... -
Oster-Insel und Brodbaum: Meilensteine im geographischen Denken von Georg Forster (1754-1794)
Baumgarten, Hans (2019)Die vorliegende Arbeit fragt anhand zweier Beispiele nach Forsters Beitrag für die Konstituierung geographischen Denkens in der Phase der Präklassischen Geographie (1750 – 1798) vor der Institutionalisierung ... -
Sperm Guidance in Zebrafish
Korsching, Kai (2024-07-24)The core challenge of the fertilization process is one of pathfinding: how do motile sperm cells locate the immotile oocyte? In some species, this process is well studied, e.g. sea urchin and human. Both species employ ... -
Investigation and Development of Quantum Chemical Solvation Models
Stahn, Marcel Siegfried (2024-07-24)The main topic of this thesis is the investigation and development of quantum chemical solvation models. In combination with modern quantum chemical methods, these models can predict various molecular properties for complex ... -
Tests of lepton universality in the rates of inclusive semileptonic B-meson decays at Belle II
Junkerkalefeld, Henrik Alexander (2024-07-23)This thesis presents two precision tests of lepton universality: the first measurement of the ratio of light-lepton branching fractions of inclusive semileptonic <em>B</em>-meson decays, <em>R(X<sub>e/μ</sub>) = ℬ(B ... -
A story about difluoromethyl-1,3,4-oxadiazoles: Synthesis and biochemical evaluation of an enigmatic novel zinc binding group for the highly selective inhibition and degradation of histone deacetylase 6
König, Beate (2024-07-22)Histone deacetylase 6 (HDAC6) is a valuable pharmaceutical target in oncological and non-oncological diseases. Classical selective HDAC6 inhibitors utilize a hydroxamic acid as zinc binding group (ZBG), which is associated ... -
Stability of Solitary Waves for the nonlinear Schrödinger Equation
Ritschl, Tillman (2024-07-22)Consider the one-dimensional focusing nonlinear Schrödinger equation with subcritical/critical exponent. <br /> This thesis examines a question derived from the so-called soliton resolution conjecture. The NLS admits ... -

Towards a systematic study of {D1,D2}-{D,D*} scattering and exotic vector states
von Detten, Leon Alexander (2024-07-18)As one of the four known fundamental forces in nature, the strong interaction is crucial for the formation of matter. Established in the early 1970s, the underlying field theory of quantum chromodynamics is embedded in our ... -
Testing large scale cosmology with MeerKAT
Wagenveld, Jonah Daniël (2024-07-17)The cosmic radio dipole is an anisotropy in the number counts of radio sources, analogous to the dipole seen in the cosmic microwave background (CMB). Measurements of the radio dipole with large radio surveys have shown ... -
Sunyaev-Zeldovich power spectrum measurements predictions for upcoming ground-based telescopes
Charmetant, Maude (2024-07-17)This work aimed to assess the detectability of the Sunyaev-Zeldovich (SZ) effects for upcoming highresolution ground-based telescopes such as the Simons Observatory (SO) and Fred Young Submillimeter Telescope (FYST). SZ ... -
A census on the gas content of star-forming galaxies over the past 11 billion years of the universe
Wang, Tsan-Ming (2024-07-17)With the advent of the Atacama Large Millimeter/submillimeter Array (ALMA), we now have the opportunity to measure the physical properties of the cold, dense, star-forming interstellar medium (ISM) even in distant, ... -

Synthesis and Characterization of Histone Deacetylase (HDAC) Inhibitors and PROTACs
Kraft, Fabian (2024-07-11)Histone deacetylases (HDACs) are a class of enzymes that remove acyl groups from ε-N-lysine residues of histone and non histone proteins. There are 18 human HDAC isoforms, of which 11 have a Zn2<sup>+</sup> ion in their ... -
PDE-based Lossless Medical Image Compression
Jumakulyyev, Ikram (2024-07-09)In this dissertation, our scientific goal is to investigate the potential of Partial Differential Equations (PDEs) for designing a lossless medical image compression codec. <br /> The dissertation consists mainly of ... -
Effects of habitat fragmentation on herpetofauna in Southeast Asia: From broad scale responses to fine scale responses in an ever-changing anthropogenic landscape
Tan, Wei Cheng (2024-07-05)Habitat loss and fragmentation are undoubtedly significant drivers of biodiversity loss worldwide, with Southeast Asia being a hotspot of biodiversity and facing numerous anthropogenic pressures. However, the impacts of ... -
