Enriching Text-Based Human-Machine Interactions with Additional World Knowledge
(2022-09-19)In the last decade, the world has witnessed a massive upheaval in intelligent systems' design and development, especially for systems that can interact with humans. Such systems, capable of real-time interaction with end ... -
Simulation of time-periodic and topological tight-binding systems with plasmonic waveguide arrays
(2022-09-16)Floquet engineering, the control by external time-periodic forcing, is a powerful tool to manipulate different quantum systems. The underlying principle is that driving a system periodically with frequency w induces ... -
Atomic-scale friction study on Au(111) under electrochemical conditions
(2022-09-14)In this study, lateral force microscopy (LFM) has been employed to investigate the frictional behavior on the surface of an electrode and the role of adsorbates, which correlates with interactions occurring at the interface. ... -
Pnictogenide and Chalcogenide Zintl Phases via Solid State and Solvothermal Syntheses
(2022-09-08)This work concentrated on the synthesis of new Zintl phases, especially focusing on the synthesis of new polyarsenides and chalcogenides. Through high temperature synthesis, the compounds Ba3As4, Ba3As2O and K3Ba7(As3)3O ... -
Analysis of Elliptic and Parabolic Partial Differential Equations Based on Carleson Measures
(2022-09-02)This thesis proposes a new technique to analyze nonlinear elliptic and parabolic partial differential equations by exploiting the knowledge generated by the associated Carleson measure characterization of admissible data ... -
A LAsMA Survey of the Milky Way: Effects of Feedback on Molecular Clouds
(2022-09-02)The advent of radio and (sub) millimetre astronomy has opened the world of molecular clouds (MCs) to astronomers' wonder. At the turn of the 21st century, MC surveys have helped us better understand them. How MCs form, ... -
Complementary adaptations of bacterial membranes to low temperatures
(2022-08-31)The membrane of bacteria is a crucial component that separates the cell from its environment and forms the site of essential functions such as energy generation, nutrient uptake, and sensing. Some bacteria can adapt their ... -
Interaction of surfactants with leaf surfaces: Analysis of time-dependent changes in leaf surface wetting, foliar uptake of surfactants and surfactant-induced transcriptomic changes in barley leaves
(2022-08-31)Since a long time it is well known, that the cuticle covering above ground primary plant organs and provides a barrier against uncontrolled water loss between the plant and the atmosphere. In plant protection one of the ... -
Next-generation phenotyping for rare Mendelian disorders
(2022-08-31)Worldwide, rare genetic disorders affect more than 6.2% of the population. The long diagnostic process is often called the ‘diagnostic odyssey.’ With the recent advances in computer vision, many next-generation phenotyping ... -
Methanogenese und Energiekonservierung in drei ungewöhnlichen methanogenen Archaea
(2022-08-31)Die vorliegende Arbeit befasste sich mit unterschiedlichen Aspekten der Methanogenese und des Energiestoffwechsels der methanogenen Archaeen <em>Methanomassiliicoccus</em> (<em>Mmc.</em>) <em>luminyensis</em>, <em>Methan ... -
Einfluss von Maßnahmen zur Verbesserung der Arzneimitteltherapiesicherheit im Krankenhaus auf die Inzidenz vermeidbarer unerwünschter Arzneimittelwirkungen bei älteren Patienten
(2022-08-31)Zur Erhöhung der Arzneimitteltherapiesicherheit (AMTS) stehen heutzutage verschiedene Interventionen zur Verfügung. So sollte im Rahmen des High-5s-Projekts der WHO Medication Reconciliation erstmals an deutschen Krankenhäusern ... -
Machine learning for monitoring groundwater resources over Europe
(2022-08-30)Groundwater (GW) is an important natural resource for Europe and the world, and has been affected by extreme weather and climate, e.g., summer heat waves and droughts, and human overexploitation. As climate change and human ... -
Maximizing Information from User-Clicks for Efficient Instance Segmentation in Images
(2022-08-29)Interactive instance segmentation allows users to select and obtain accurate pixel-level masks for objects of interest by providing inputs such as clicks, scribbles, or bounding boxes. It has always been a problem of ... -
Enhanced skin permeation of small molecules via retention of enhancer substances in matrix-type transdermal patches
(2022-08-29)A long-standing approach to improve the transdermal drug permeation is to use chemical penetration enhancers. Those substances reduce the barrier properties of the skin, especially of the stratum corneum, and facilitate ... -
Torsion classes, wide subcategories and maximal green sequences
(2022-08-26)In this thesis, the relationship between torsion classes and wide subcategories in module categories of finite dimensional algebras is studied. Of particular interest are wide intervals, which are interval subsets of the ... -
Casson-Whitney unknotting, Deep slice knots and Group trisections of knotted surface type
(2022-08-26)In this thesis, we study knotted surfaces in 4-dimensional manifolds from three different but interconnected perspectives. <br /> In the first part, we introduce a measure of 'distance', or rather 'length', between ... -
Die Aufklärung eines neuartigen Pentose-Stoffwechsels und die Möglichkeit einer Homosuccinat-Fermentation in Darmbakterien
(2022-08-26)In der vorliegenden Arbeit wurde der Pentose-Metabolismus des bedeutsamen Darmbakteriums <em>Prevotella</em> <em>copri</em> (<em>P.</em> <em>copri</em>) untersucht, und es wurde analysiert, ob die Umsetzung einer ... -
Annelid chaetae: Ultrastructure, arrangement and phylogenetic significance
(2022-08-26)With approximately 21,000 described species, Annelida represent one of the largest and best studied group of marine invertebrates. Their anatomy is characterized by a metameric organization, which covers potential for an ... -
