L2-index theory, the Chern conjecture, and manifolds of special holonomy
Hoffmann, Michael (2014-12-12)In this dissertation we study a conjecture attributed to Chern and Hopf, a generalization of Atiyah's L2-index theorem used by Gromov to prove said conjecture for Kähler manifolds, and an extension to ... -
N-Heterocyclic Carbene Palladium Pincer Complexes: Synthesis, Aggregations and Catalytic Applications
Jagadeesh, Malineni (2011-11-29)The work presented herein describes an investigation of a new class of pyridine-bridged bis- (benz)imidazolium salts and N-heterocyclic pincer carbene complexes derived there from, as well as their implication as homogenious ... -
A p-Adic 6-Functor Formalism in Rigid-Analytic Geometry
Mann, Lucas (2022-08-01)We develop a full 6-functor formalism for $p$-torsion étale sheaves in rigid-analytic geometry. More concretely, we use the recently developed condensed mathematics by Clausen--Scholze to associate to every small v-stack ... -
p-Kazhdan-Lusztig Theory
Jensen, Lars Thorge (2018-07-03)We describe a positive characteristic analogue of the Kazhdan-Lusztig basis for the Hecke algebra of a crystallographic Coxeter system, called the p-canonical basis. Using Soergel calculus, we present an algorithm ... -
Plexin-A2 and neuropilin-2 in the axonal guidance of cranial nerves in avian embryos
Haque, Ziaul (2014-03-17)Secreted class-III semaphorins exert their effects in axon guidance and neuronal migration by binding with receptors, such as plexins and neuropilins. Neuropilins are insufficient to convey signals of their own; rather, ... -
R-Symmetries from the Orbifolded Heterotic String
Schmitz, Matthias (2014-11-20)We examine the geometric origin of discrete R-symmetries in heterotic orbifold compactifications. By analysing the symmetries of the worldsheet instanton solutions and the underlying geometry, we obtain a scheme ... -
Der Ranunculus-auricomus-Komplex in Deutschland westlich des Rheins
Schmelzer, Martin (2016-01-05)Der gegenwärtige Stand der Erforschung der Gold-Hahnenfuß-Flora (Ranunculus auricomus agg.) in Deutschland westlich des Rheins (mit Ausnahme des Saarlandes) wird dargestellt. Eine taxonomische und pflanzengeografische ... -
Wolbachia, endosymbionts of arthropods and filarial nematodes: Requirement of cell wall biosynthesis for cell division And Replication in a host cell-free culture
Vollmer, Jennifer (2013-03-13)Obligate intracellular endobacteria of the genus Wolbachia are widespread in arthropods and filarial nematodes. In disease-causing filarial nematode species, responsible for over 150 million cases of human filariasis in ... -
Embedding the DFSZ–Axino in mSUGRA with R–Parity Violation and its implications for Dark Matter
Poletanović, Branislav (2011-01-21)We embed the DFSZ axion in supersymmetry with broken R–parity. As Supersymmetry provides hundreds of free parameters we restrict ourselves to the lepton–number violating scenario in minimal supergravity models with ... -
Embeddings of groups rings and L2-invariants
Meumertzheim, Fabian (2021-06-02)The strong Atiyah conjecture for a group G, which restricts the possible values taken by L2-Betti numbers of G-CW-complexes, implies far-reaching structural statements about a canonical *-regular ring RℚG, ... -
Emergent Disorder: Nano-Domain Formation Near the First-Order Mott-Hubbard Transition
Liu, Qinyong (2012-07-23)Since the Mott-Hubbard metal-insulator transition is a first order phase transition, we can always find a phase coexistence region in the phase diagram. In this region, the metallic state and the insulating state coexists, ... -
Emergent Land Commodification and Intergenerational Land Relations in Northwestern Ghana
Mwingyine, Darius Tuonianuo (2019-08-05)In the developing world, especially in Africa, land is the main livelihood resource and a communal intergenerational asset. African land tenure has come under pressure due to growing land commodification, especially under ... -
Emerging Chemical Patterns for Virtual Screening and Knowledge Discovery
Auer, Jens Horst (2009-02-03)The adaptation and evaluation of contemporary data mining methods to chemical and biological problems is one of major areas of research in chemoinformatics. Currently, large databases containing millions of small organic ... -
Empfehlungen zur sicheren Anwendung von Arzneimitteln im Off-Label-Use in Deutschland
Bauer, Maria Luise (2019-02-19)Unter einem Off-Label-Use wird die Anwendung von Fertigarzneimitteln verstanden, die entsprechend dem Arzneimittelgesetz in Verkehr gebracht wurden, aber außerhalb des in der nationalen oder (de)zentralen Zulassung definierten ... -
Enabling wide-field, high-spatial-resolution fast transient searches on modern interferometry
Chen, Weiwei (2022-04-13)Fast transients reveal the energetic universe to us. They are usually the products of rapid and enormous energy releases. To study the physical nature behind them, we must know the subtle temporal structure of the signal ... -
Enantiomerentrennung von Polyphenolen mittels Kapillarelektrophorese
Kofink, Michael (2009-06-29)In der vorliegenden Arbeit werden Ergebnisse zur Untersuchung von phenolischen Pflanzeninhaltsstoffen (enantiomere Polyphenole) mittels enantioselektiver Kapillarelektrophorese vorgestellt. Die untersuchten Analyten stammen ... -

Palm, André (2023-04-19)Salimabromid
Das aus dem marinen Myxobakterium, Enhygromyxa salina, isolierte Polyketid, Salimabromid, wurde mit seinem neuartigen Kohlenstoffgerüst in einer enantioselektiven ... -
The endocannabinoid system and cognition
Komorowska-Müller, Joanna Agnieszka (2022-01-24)THC-treatment differentially alters spines dynamics in old and young mice
The endocannabinoid system (ECS) is a neuromodulatory system involved in cognitive processes. Increasing the ECS tone with ... -
Endogenous opioid peptides in drug addiction
Schürmann, Britta (2010-04-13)Depending on the addictive drug the opioid peptides, enkephalin and ß-endorphin vary in their contribution to reward. Conditional Penk1 knockout mice were successfully generated which allow the cell- or tissue-specific ... -
