Expression, Aufreinigung und funktionelle Untersuchungen der ABC-Transporter ABCB1 und ABCG2
Jacobs, Anna (2010-07-27)Die ABC-Transporter ABCB1 und ABCG2 beeinflussen aufgrund ihrer ubiquitären Expression in physiologischen Barrieren und ihrer breiten Substraterkennung die Pharmakokinetik vieler unterschiedlicher Arzneistoffe. Außerdem ... -
Expressionssysteme zur Untersuchung der Pederin- und Psymberin-Biosynthese aus nicht kultivierten bakteriellen Symbionten
Niederkrüger, Holger (2011-03-25)Die vorliegende Arbeit beschäftigt sich mit der Expression und Charakterisierung von Enzymen der Pederin- und Psymberin-Biosynthese sowie mit den Fortschritten in der heterologen Expression des Pederin-Genclusters. Pederin ... -
Extensibility of Association Schemes and GRH-Based Deterministic Polynomial Factoring
Arora, Manuel (2013-03-21)The subject of the present work is the application of the theory of combinatorial schemes to problems in computational algebra. The principal notions of combinatorial schemes which are studied in this work are association ... -
External Control of Many-Body Quantum Systems
Halaţi, Cătălin-Mihai (2021-10-05)In strongly correlated many-body quantum systems, the complex interplay between a large number of degrees of freedom and the presence of various competing energy scales leads to rich phase diagrams, but also renders these ... -
External Spanier-Whitehead duality for C-spectra and applications to C-homology theories
Lackmann, Malte Felix (2021-07-19)The thesis constructs a Spanier-Whitehead type duality functor relating finite C-spectra to finite Cop-spectra, where C is a topological index category. We prove that every C-homology theory is given by taking the homotopy ... -
Die externe Strahlführung für Detektortests X3ED an der Elektronen-Stretcher-Anlage ELSA
Heurich, Nikolas (2017-12-12)Um das Verständnis des Aufbaus der Materie zu erweitern sind Experimente mit hochenergetischen Teilchen erforderlich. Diese Teilchenstrahlen werden beispielsweise durch Kreisbeschleuniger bereitgestellt. Aufseiten der ... -
Extra- und intrazelluläre Laccasen der acidophilen schwarzen Hefe Hortaea acidophila
Bend, Jutta (2006)<i>Hortaea acidophila</i>, die aus einem Medium mit pH 0,6 isoliert wurde, gehört zur ascomycetischen Ordnung der Dothideales und bildet Melanin, weshalb zu Beginn der vorliegenden Arbeit das Vorliegen einer Laccase in ... -
Extracellular ATP Signaling is Linked to Endocytic Vesicle Recycling in Root Apex
Kagenishi, Tomoko (2016-06-09)Plants are sessile organisms, the roots of which exudate a large number of chemical compounds into the rhizosphere that contain several chemicals and microbes. It is known that at the root apex, the transition zone is ... -
Extracellular Phosphorylation of the Amyloid β-Peptide Promotes Aggregation
Kumar H.S., Sathish (2009-07-21)Alzheimer’s disease (AD) is the most prevalent, progressive neurodegenerative disorder and its incidence is increasing with the aging population worldwide. The presence of extracelluar neuritic plaques containing amyloid ... -
Extracting and Exploiting Structure in Point Clouds for Editing and Interpolation
Aiteanu, Fabian (2022-12-22)Modern movies and computer games employ rich virtual environments to offer the consumer an immersive experience. Digital models are often easier and more cost-efficient to create than acquiring real-world film footage ... -
Extracting Hadamard Coefficients from Green's Operators
Ronge, Lennart (2023-03-20)We develop a formula for the diagonal values of the Hadamard coefficients associated to a normally hyperbolic operator on a globally hyperbolic spacetime in terms of the advanced and retarded Green's operators. We develop ... -
Extraction of Fragmentation Functions from Charged Kaon and Pion Production at COMPASS
Panknin, Regine Antje (2013-12-16)Quark helicity distributions can be accessed by measuring spin asymmetries in polarised deep-inelastic scattering, but for a full flavour separation the precise knowledge of quark fragmentation functions is essential. Those ... -
Extremal Processes in Branching Brownian Motion and Friends
Hartung, Lisa Bärbel (2016-07-21)In recent years there has been increasing interest in understanding the extremal behaviour of strongly correlated systems.<br /> We start the introduction by recalling the main results for independent, identically distributed ... -
Extremes of the discrete Gaussian free field in dimension two
Fels, Christian Joachim Maximilian (2021-03-26)In recent years, there have been many advances towards an understanding of the extreme value theory of <em>log-correlated random fields</em>. Log-correlated random fields are conjectured to compose a universality class ... -
Fabrication of Fresnel Zone Plates for Soft X-Ray and EUV Microscopy by Ion Beam Lithography
Overbuschmann, Johannes (2014-12-05)Fresnel zone plates are used as lenses for microscopes in the extreme ultraviolet (EUV) and the soft X-ray (SXR) parts of the electromagnetic spectrum. This thesis describes a novel approach for the fabrication of these ... -
Facies and sequence architecture of mixed carbonate-siliciclastic depositional systems during transforming sag to foreland basin geometries - “Sundance Basin”, Middle and Late Jurassic, western United States
Büscher, Olaf (2004)During the Middle Jurassic, the symmetric intracratonic “Sundance Basin” in the western portion of the North American continent was overridden by the approaching tectono-orogenic front of an early Cordilleran orogeny and ... -
Facility Location and Clock Tree Synthesis
Maßberg, Jens Uwe (2010-04-13)The construction of clock trees and repeater trees are major challenges in chip design. Such trees distribute an electrical clock signal from a source to a set of sinks on a chip. On recent designs there can be millions ... -
Factorability, Discrete Morse Theory and a Reformulation of K(π, 1)-conjecture
Ozornova, Viktoriya (2013-02-20)The first aim of this thesis is to study factorable groups and monoids. We give a new family of examples for factorability structures, provided by Garside theory, in particular, we provide a factorability structure on braid ... -
Factorable Groups and their Homology
Visy, Balázs (2011-07-04)In this thesis we introduce the class of factorable groups. These are normed groups together with a norm preserving decemposition (or factorization) of each group element into two factors. <br /> Already the norm alone ... -
Factorable Monoids: Resolutions and Homology via Discrete Morse Theory
Heß, Alexander (2012-07-26)We study groups and monoids that are equipped with an extra structure called factorability.<br /> A factorable group can be thought of as a group G together with the choice of a generating set S and a particularly well-behaved ...
