High precision lysimeters improve our understanding of water cycle and solute transport dynamics
(2018-11-28)Water is the most precious natural resource on earth. Understanding the movement of water and dissolved substances between the different compartments soil, vegetation, and atmosphere is of crucial importance to resolve ... -
High precision timing
(2019-04-30)Pulsars are highly magnetised, fast spinning neutron stars, formed after a supernova explosion. Pulsars have been used to study a wide range of physical and astrophysical phenomena. The majority of science that we can do ... -
High redshift galaxy groups as seen by Athena
(2022-01-03)The first massive galaxy groups in the Universe are predicted to have formed at redshifts well beyond two. Baryonic physics, like stellar and active galactic nuclei (AGN) feedback in this very active epoch, are expected ... -
High resolution magnetic field measurements in high-mass star-forming regions
(2011-09-22)Three different scenarios have been proposed to explain the formation of high-mass stars. In one of these scenarios, core accretion, massive stars form through gravitational collapse, which involves disk-assisted accretion ... -
High Throughput Screening and mRNA-Display Selection for the Identification of Biologically Functional Molecules
(2006)Biologically functional molecules with desired properties have proven to be invaluable tools for investigating biological systems. Moreover, the identification of those functional molecules is a crucial task in modern drug ... -
High-energy processes in low-mass protostars – an X-ray to radio multi-wavelength perspective
(2007)High-energy processes in protostars remain poorly understood. Only after the recently finished Chandra Orion Ultra-deep Project (COUP), statistically significant information on X-ray emission from Young Stellar Objects ... -
High-Level Facade Image Interpretation using Marked Point Processes
(2016-07-06)In this thesis, we address facade image interpretation as one essential ingredient for the generation of high-detailed, semantic meaningful, three-dimensional city-models. Given a single rectified facade image, we detect ... -
High-Precision Surface Inspection: Uncertainty Evaluation within an Accuracy Range of 15μm with Triangulation-based Laser Line Scanners
(2014-01-02)Triangulation-based range sensors, e.g. laser line scanners, are used for high-precision geometrical acquisition of free-form surfaces, for reverse engineering tasks or quality management. In contrast to classical tactile ... -
High-Quality Simplification and Repair of Polygonal Models
(2009-11-05)Because of the rapid evolution of 3D acquisition and modelling methods, highly complex and detailed polygonal models with constantly increasing polygon count are used as three-dimensional geometric representations of objects ... -
High-resolution and Large Field Microscopy of Expanded Mouse Brain Sections and Human Brain Organoids
(2024-04-08)Connectome analysis, the comprehensive mapping of neural connections within an organism nervous system has long been a formidable challenge in neuroscience. Traditional methods often fall short in providing a holistic view ... -
A high-resolution regional reanalysis for Europe and Germany: Creation and Verification with a special focus on the moisture budget
(2015-10-22)Atmospheric reanalyses represent a state-of-the-art description of the Earth‘s atmospheric state over the past years or decades. They are comprised of a numerical model for the solution of the equations of motion describing ... -
High-Resolution Study of Selected Intraday Variable Sources
(2006)Radio waves are affected by the ionized interstellar medium through which they pass. Wide ranges of scattering effects can occur and influence the observed characteristics of compact radio objects. Distinguishing between ... -
High-Spin γ-Ray Spectroscopy of 124Ba, 124Xe and 125Xe
(2009-08-27)Rotational spectra had been observed for the first time in excited atomic nuclei in 1938. This observation was attributed to the deviation from spherical shape. In quantum mechanics, when a perfectly spherical system ... -
High-Throughput Phenotyping of Photosynthesis Traits in Durum Wheat Under Drought Stress Using Light-Induced Fluorescence Transients
(2022-03-24)Agriculture in the twenty-first century faces the double challenge of feeding a growing population in a changing climate. Food security will increasingly rely on the active release of stable high-yielding cultivars with ... -
Higher cross-ratios and geometric functional equations for polylogarithms
(2016-08-31)In this work we define and study a generalization of the classical cross-ratio. Roughly speaking, a generalized cross-ratio is a function of n points in a projective space that is invariant under the change of coordinates ... -
Higher Green’s functions for modular forms
(2009-03-12)Higher Green functions are real-valued functions of two variables on the upper half plane which are bi-invariant under the action of a congruence subgroup, have logarithmic singularity along the diagonal, but instead of ... -
Higher-order statistics in cosmic shear
(2023-08-23)The humble goal of cosmology is to understand the Universe as a whole. In the last decades, the Lambda Cold Dark Matter model has proven itself as the standard model of cosmology by explaining the majority of cosmological ... -
Higher-Order Tensors and Differential Topology in Diffusion MRI Modeling and Visualization
(2019-05-02)Diffusion Weighted Magnetic Resonance Imaging (DW-MRI) is a noninvasive method for creating three-dimensional scans of the human brain. It originated mostly in the 1970s and started its use in clinical applications in the ... -
Hilbert transforms and maximal operators along planar vector fields
(2015-07-16)In harmonic analysis, there is a conjecture (attributed to Zygmund) stating that the directional maximal operator along a Lipschitz planar vector field is weakly bounded on L^2. In this thesis, we present some recent ... -
Hilfsuntereinheiten kontrollieren Funktion und subzelluläre Verteilung von AMPA-Rezeptoren in NG2-Gliazellen des sich entwickelnden Hippokampus
(2024-01-24)NG2-Gliazellen verfügen über funktionelle Glutamat-Rezeptoren vom AMPA-Subtyp und werden als einzige nicht-neuronale Zellen im Gehirn direkt von Nervenzellen synaptisch innerviert. Der Hippokampus gilt als Schlüsselregion ...
