A Statistical Analysis of Surface Ozone Variability Over the Mediterranean Region During Summer
Kaffashzadeh, Najmeh (2018-10-11)The Mediterranean (Med) region contains the highest surface ozone (O3surf) concentrations in Europe, in particular in summer. Although atmospheric chemistry models (ACMs) are able to reproduce the regional O3surf maximum ... -
Statistical and Dynamical Downscaling of Numerical Climate Simulations: Enhancement and Evaluation for East Asia
Simon, Thorsten (2014-11-28)The overall aim of this thesis is to present methods, which improve evaluating dynamical downscaling approaches or enhance statistical downscaling schemes. These methods are illustrated along examples of both approaches ... -
Statistical mechanics of gradient models
Hilger, Susanne (2019-07-18)In this thesis, we consider gradient models on the d-dimensional discrete lattice. These models serve as effective models for interfaces and are also known as continuous Ising models . The height of the interface ... -
Statistical properties of cosmological correlation functions
Wilking, Philipp (2015-04-24)Correlation functions are an omnipresent tool in astrophysics, and they are routinely used to study phenomena as diverse as the large-scale structure of the Universe, time-dependent pulsar signals, and the cosmic microwave ... -
Statistical Quality Assurance and Peer Review in Primary Data Publication
Düsterhus, André (2013-01-23)Publication of results is an elementary part of scientific work. Started in in 17th century with the traditional scientific publications several new forms emerged in recent years, triggered by the digital ... -
Statistische Methoden zur familienbasierten Assoziationsanalyse
Hahn, Andreas (2000)Die vorliegende Arbeit stellt eine Methode zur Auffindung krankheits(mit-)verursachender Gene auf den menschlichen Chromosomen vor. Im Unterschied zu bisher bekannten Methoden der Assoziationsanalyse wird die Information ... -
Steep, Spatially Graded Recruitment of Feedback Inhibition by Sparse Dentate Granule Cell Activity
Braganza, Oliver (2016-05-24)The dentate gyrus of the hippocampus is thought to subserve important physiological functions, such as 'pattern separation'. In chronic temporal lobe epilepsy, the dentate gyrus constitutes a strong inhibitory gate for the ... -
Stellar populations in gravitationally bound systems
Jeřábková, Tereza (2020-08-21)The understanding of how, which, where and when stars form provides important information for the vast majority of astronomical fields. Star-formation has a complex multi-scale physical nature. Stars form in dense sub-parsec ... -
Stereo- und Regioselektivität in der homogen katalysierten Hydrierung von Alkinen und Allenen: Aufklärung von Reaktionsmechanismen mit der PHIP-NMR-Spektroskopie
Schleyer, Dana (2000)Homogen katalysierte Hydrierreaktionen wurden mit der PHIP-NMR-Spektroskopie untersucht. Die Hydrierung mit Parawasserstoff führt zu verstärkten Emissions- und Absorptionssignalen im NMR-Spektrum des Produktes durch selektive ... -
Stereoselektive Diolsynthese mit Lyasen und Oxidoreduktasen: Entwicklung eines kontinuierlichen Verfahrens
Kihumbu, David (2007)Optisch aktive vicinale Diole stellen wichtige Vorläufermoleküle für die Synthese pharmazeutisch interessanter Wirkstoffe dar. Im Rahmen der Dissertation konnte eine stereoselektive enzymatische Synthese aller vier möglichen ... -
Stereoselektive Polyolsynthese zur Untersuchung von Wasserstoffbrückenbindungen mittels IR-Spektroskopie
Ueberlein, Sven (2020-12-11)Um die anomalen Eigenschaften des Wassers gänzlich zu verstehen, ist die intensive Untersuchung von Wasserstoffbrücken erforderlich. IR-spektroskopische Messungen vernetzter Flüssigkeiten liefern dabei eine Fülle an ... -

Kaiser, David (2014-03-10)Für ein tieferes Verständnis der starken Wechselwirkung und des Aufbaus der Nukleonen untersucht das CBELSA/TAPS-Experiment im Rahmen des Sonderforschungsbereichs SFB/TRR 16 "Elektromagnetische Anregung subnuklearer Systeme" ... -
Stochastic and deterministic models for the evolution of heterogeneous populations: Multiscale approximation and applications to melanoma T-cell therapy
Kraut, Anna Katharina (2020-07-24)Stochastic modelling at the interface of mathematics and life sciences has gained great attention over the last decades. The study of many complex biological systems requires models taking random effects into account. Both ... -
Stochastic calculus in Riemannian polyhedra and martingales in metric spaces
Christiansen, Tom (2007)The classical stochastic calculus of semimartingales is generalized to semimartingales in polyhedra. The main tool is a local Ito formula for piecewise smooth functions which is given in terms of so-called directional local ... -
Stochastic individual-based models of adaptive dynamics and applications to cancer immunotherapy
Baar, Martina Vera (2017-03-24)In this thesis stochastic individual-based models describing Darwinian evolution of asexual, competitive populations are studied. A specialization of these models is developed to describe tumor development under immunotherapy ... -
Stochastic Interacting Particle Systems and Nonlinear Partial Differential Equations from Fluid Mechanics
Philipowski, Robert (2007)We derive stochastic particle approximations for two nonlinear partial differential equations from fluid mechanics: the porous medium equation and the three-dimensional Navier-Stokes equation. We associate interacting ... -
