Experimental Near-Field Characterization of Plasmonic Nanostructures
(2021-01-13)The spatial resolution of conventional optical technologies is fundamentally limited by diffraction due to the wave nature of light. A promising platform to overcome this diffraction limit in nanophotonic applications is ... -
Weakly and Semi Supervised Semantic Segmentation of RGB Images
(2021-01-11)Teaching machines semantic scene understanding from RGB images received a lot of attention in recent years, since this ability is crucial for several applications like autonomous driving, robotics or video surveillance. ... -
Function of Reelin Signaling in the Tangential Migration of Dopaminergic Neurons
(2021-01-07)Midbrain dopaminergic neurons (mDA neurons) are involved in the regulation of voluntary movement, reward behavior and cognitive processes. mDA neurons are born in the floor plate of the ventral midbrain, from where they ... -
Three Pion Scattering at Maximal Isospin from Lattice QCD at Physical Mass
(2021-01-07)In this work the scattering of two pions in $I = 2$ and three pions in $I = 3$ is analyzed with lattice QCD. The process is computed on three Wilson clover twisted mass ensembles generated by the ETMC with total momentum ... -
Synthese und Reaktionen von phosphorfunktionalisierten 1,3-Dithiol-2-thionen
(2021-01-05)Die Dissertation "Synthese und Reaktionen von phosphorfunktionalisierten 1,3-Dithiol-2-thionen" beschreibt die Darstellung von tricyclischen 1,4-Dihydro-1,4-diphosphininen, die 1,3-Dithiol-2-thion-Einheiten tragen. Zugleich ... -
Microevolutionary processes and taxonomic investigations of the Atacama Desert flora
(2020-12-22)(noch nicht zugänglich / not yet accessible) -
Experimental studies on small diameter carbon dioxide evaporators for optimal Silicon Pixel Detector cooling
(2020-12-18)Since recent years the Large Hadron Collider at CERN and its experiments are the subject of upgrade programs, which are necessary to increase the foreseen collision rates and the amount of data to be gathered for the ... -
Occlusion and Function of Triconodont Dentitions
(2020-12-18)(noch nicht zugänglich / not yet accessible) -
Influence of cyclic mechanical strain on tissues of the central nervous system
(2020-12-17)Although the brain is the softest tissue of the human body, cells embedded in the brain are responding to physiological mechanical cues. Tissue homeostasis is, therefore, not only dependent on chemical cues (e.g. growth ... -
Efficient Algorithms for Routing a Net Subject to VLSI Design Rules
(2020-12-17)In this thesis we consider detailed routing, an important step in the design of integrated circuits. On large instances detailed routing requires packing millions of node-disjoint Steiner trees into a graph with hundreds ... -
Characterization of the Sulfite-Generating rDsrABL Complex of Allochromatium vinosum
(2020-12-16)Microbial pathways of sulfur dissimilation have strongly contributed to the evolution of the biogeochemical sulfur cycle and still play a major role in it today. Dissimilatory sulfite reductases, which occur in both sulfate ... -
State-dependent processing of Dentate Gyrus granule cell activity in-vivo
(2020-12-16)The ability to form dissimilar neural activity patterns from similar sensory driven inputs is a phenomenon found in all vertebrates, called pattern separation. In mammals, pattern separation is closely related to a subregion ... -
Structural and functional characterization of the HPV16 entry platform on the cell surface
(2020-12-16)Human papillomaviruses (HPV) are small, non-enveloped DNA viruses that infect skin and mucosa tissues. Among the family, HPV16 is one of the most oncogenic subtypes responsible for a variety of cancers, including cervical, ... -
Hormone und Demenz: Eine pharmakoepidemiologische Analyse
(2020-12-16)Die Untersuchung potentieller Risikofaktoren für eine Demenzerkrankung ist ein wichtiger Bestandteil der primären Prävention. Die weite Verbreitung der Einnahme von Hormonen und hormonbeeinflussenden Medikamenten für ... -
Die Phyllosphäre als Lebensraum für Bakterien: Mechanismen der Interaktion epiphyller Bakterien mit der pflanzlichen Kutikula
(2020-12-16)Die Phyllosphäre stellt einen lebensfeindlichen Lebensraum dar. Jedoch gibt es epiphytisch lebende Bakterien, die diesen Lebensumständen entgegenwirken und Mechanismen entwickelt haben, in diesem kargen Lebensraum Nährstoffe ... -
Control of ion and neurotransmitter homeostasis by hippocampal astroglial networks
(2020-12-16)The present study addressed the contribution of astrocytic gap junction channels to extracellular K+ clearance. Astrocyte form large networks through gap junction coupling that enables intercellular communication ... -
Analytic Bipedal Walking with Fused Angles and Corrective Actions in the Tilt Phase Space
(2020-12-15)As humanoid robots start to move from research labs to workplace environments and homes, the topic of how they should best and most reliably locomote in the face of unknown disturbances will be a topic of increasing ... -
The effect of Western diet on the transcriptional memory of monocyte-derived cells
(2020-12-11)Monocytes and monocyte-derived cells are very plastic and versatile immune cells that react to different environmental signals. These signals include not only pathogen-associated molecular patterns (PAMPs) and damage-associated ... -
Don't Blame Developers! Examining a Password-Storage Study Conducted with Students, Freelancers, and Company Developers
(2020-12-11)Authentication systems are a major concern for the usable security and privacy community. Twenty years ago, the seminal work “Users Are Not The Enemy” [1] by Adams and Sasse initiated a user-centred approach to research. ... -
Efficient Capture of Multispectral Reflectance of Complex Surfaces
(2020-12-11)The synthetic generation of photo-realistic images is a long-standing goal in the area of Computer Graphics. The applications are numerous, including virtual prototyping, advertisement and visual effects in movies. Since ...
