Silicon Compounds in Low Oxidation States Supported by a Cyclic (Alkyl)(Amino)Carbene: Synthesis, Structure and Reactivity
(2023-03-09)<strong>Abstract:</strong> Silicon compounds in low oxidation states, especially dihalosilylenes (SiX<sub>2</sub>), are highly unstable molecules, which are involved as fleeting intermediates in the industrial production ... -
Silvicultura en el Sur de Chile: Investigaciones ecológicas y experiendas recogidas en una forestadón en La Ensenada
(1960)El bosque es una realidad determinada por condiciones geográficas. El emplazamiento, el clima y el suelo son factores naturales que facilitan o entorpecen la formación y el desarrollo del bosque. Como los factores citados ... -
Similarities and Representations of Graph Structures
(2021-06-01)Graphs are a natural representation for diverse systems ranging from social networks to the Web and brain structure. Even when data is not interconnected explicitly, it is often convenient to convert it into a graph for ... -
Similarities of stress granules and cytosolic prions
(2019-02-06)Eukaryotic cells contain several organelles that lack a delimiting membrane. These membrane-less organelles take over important functions within the cell and influence biological reactions by condensing nucleic acids and ... -
Similarity, Retrieval, and Classification of Motion Capture Data
(2007)Three-dimensional motion capture data is a digital representation of the complex spatio-temporal structure of human motion. Mocap data is widely used for the synthesis of realistic computer-generated characters in data-driven ... -
Die Simulation der antimikrobiellen Wirkung ausgewählter Lantibiotika mittels kombinierter Biosensortechniken
(2007)Nach Angaben aus dem Jahr 2004 ist die Sepsis die dritthäufigste Todesursache in Deutschland. Weltweit sind Infektionskrankheiten nach Aussagen der Weltgesundheitsorganisation WHO die häufigste Todesursache. Dass ... -
Simulation of Bone Remodeling Process around Dental Implant During the Healing Period
(2021-07-05)This interdisciplinary thesis deals with the numerical investigation of bone remodeling around dental implants during the healing period with regard to biomechanical aspects. The aim of the study was to develop algorithms ... -
Simulation of Ion Migration with Particle Dynamics and the Heat-Poisson-Nernst-Planck System
(2016-12-22)In this thesis we study the numerical simulation of ion migration and its coupled thermal effects. Many of the existing mathematical models in this area of research implicitly rely on thermal equilibrium conditions, despite ... -
Simulation of mesoscale patterns and diurnal variations of atmospheric CO2 mixing ratios with the model system TerrSysMP-CO2
(2016-06-28)With the recent trend towards precise regional climate simulations information on the spatial distribution of CO<sub>2</sub> sources and sinks at the mesoscale scale becomes more important. A common method to obtain these ... -
Simulation of the Periodontal Ligament During the Initial Phase of Orthodontic Tooth Movement
(2020-09-22)The present work is concerned with the simulation of the periodontal ligament response to force in the initial phase of orthodontic tooth movement. This is based on two previous investigations at the Universitätsklinikum ... -
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 ... -
Simulation pulsverarbeitender neuronaler Netze: eine ereignisgetriebene und verteilte Simulation pulsverarbeitender neuronaler Netze
(2003)In dieser Arbeit werden die Eigenschaften von pulsverarbeitenden Neuronalen Netzen (PVNN) untersucht und eine daraufhin optimierte Lösung in Form des Simulationssystems SPIKELAB vorgestellt. SPIKELAB implementiert eine ... -
Simulation seltener Ereignisse mittels Importance Sampling unter besonderer Berücksichtigung Markovscher Modelle
(2004)Diese Arbeit behandelt die simulative Analyse seltener Ereignisse und dabei insbesondere die statistische Schätzung von Wahrscheinlichkeiten seltener Ereignisse unter Verwendung des Varianzreduktionsverfahrens "Importance ... -
Simulations with the PANDA Micro-Vertex-Detector
(2014-12-12)The <span style="text-decoration:overline;">P</span>ANDA experiment will be built at the upcoming FAIR facility at GSI in Darmstadt, featuring antiproton-proton reac- tions hadron physics in a medium energy range. Charm ... -
Simulationsrechnungen zur Positronenannihilation in Aluminiumlegierungen zur Untersuchung der Ausscheidungsbildung
(2010-12-21)Hochfeste Aluminiumlegierungen verdanken ihre Eigenschaften kleinen, fein verteilten Ausscheidungen von Legierungsatomen. Zum besseren Verständnis der Temperaturbehandlung, die benötigt wird, um die Ausscheidungsbildung ... -
Simultaneous identification of nucleotide-modified aptamers with different properties by multiplexed click-SELEX
(2020-06-18)Voltage-gated sodium channels (VGSC) are important key regulators in excitable tissue that initiate and propagate the action potential in specifically excitable tissue such as brain nerves or muscle. In order to understand ... -
Simultaneous multichannel photometry with BUSCA
(2004)This thesis deals with the multicolour simultaneous camera BUSCA (Bonn University Simultaneous CAmera), which was build at the Sternwarte of the University of Bonn for the the 2.2m telescope at the Calar Alto Observatory ... -
Sind Anhydromuramylpeptide auch bei Aeromonas spp. die Mediatoren für die Induktion der chromosomalen β-Laktamase?
(2003)Die chromosomalen β-Laktamasen gramnegativer Bakterien stellen eine Bedrohung für die Therapie von Infektionen mit β-Laktam-Antibiotika dar. Diese hydrolytischen Enzyme sind in der Regel induzierbar, erhalten jedoch eine ... -
Single atom interferometers and Bloch oscillations in quantum walks
(2013-05-22)The deliberate coherent manipulation of a single atom's spin and position in an optical lattice has great potential as a primitive for future quantum simulators. This thesis investigates position control on ultracold Caesium ...
