Climate variability and change in the Altai-Dzungarian region and its hydrological impact
(2023-10-09)The Altai Mountains and also other mountainous areas of Central Asia experienced intermittent cold periods during the 20th-century warming of the Northern Hemisphere. Since the recent cold period in the 1980s, subsequent ... -
Climate- and Human-Induced Vegetation Changes in Northwestern Turkey and the Southern Levant since the Last Glacial
(2017-04-20)Northwestern Turkey and the southern Levant are key regions for studying vegetation and climate developments during migration phases of modern humans and the origin and expansion of agriculture. Both regions have a long ... -
Climate-Mining interactions and the effects on rural resilience: Perspectives from southwestern Ghana
(2024-02-20)Exploitation of natural resources including minerals contribute immensely toward development at different scales across West Africa. Mining is a prominent land-use practice within the region owing to the deposition of ... -
Cloning and expression of deoxyhypusine synthase from Plasmodium vivax and Theileria parva as an approach for target evaluation in anti-parasitic chemotherapy
(2009-09-08)An important issue facing global health today is the need for new, effective and affordable drugs against malaria and a veterinary parasitic disease named Theileriosis, particularly in resource-poor countries. The parasite ... -
The cloudy HI halo of the Milky Way
(2008)Based on the analysis of the Milky Way soft X-ray background and all sky 21-cm line surveys models show that the gaseous Galactic Halo has two components, one of hot plasma with log[T(K)]=6 and a neutral component. If ... -
Clumpy Dust Tori in Active Galactic Nuclei
(2008)Active Galactic Nuclei (AGN) are amongst the most luminous objects in the universe. The source of their activity is accretion onto a supermassive black hole in the center of the galactic nucleus. The various phenomena ... -
Cluster analysis of European surface ozone observations for evaluation of MACC reanalysis data
(2015-04-22)The high density of European surface ozone monitoring sites offers good opportunities for investigation of the regional ozone representativeness and for evaluation of chemistry climate models. In this thesis we analyze ... -
Clusterpolitik und Clusterinitiativen in Nordrhein-Westfalen: Eine prozessorientierte Garbage-Can-Analyse im politischadministrativen Mehrebenensystem
(2013-12-16)Die Arbeit leistet einen Beitrag zur Beantwortung der Frage, wie und warum sich Clusterinitiativen und -politiken im politisch-administrativen Mehrebenensystem herausbilden und wie sich die verschiedenen Maßstabsebenen ... -
CNP-expressing progenitors display strikingly differential oligodendroglial or multipotent fates, as assessed by two Cre reporter lines
(2012-12-21)In this study, I employ a mouse line in which Cre is knocked-in for the 2’,3’ -cyclic nucleotide 3’ –phosphodiesterase (CNP) gene and compare the fates of CNP-Cre ex-pressing OPCs between two Cre reporters: Z/EG and ... -
Coarsening processes in thin liquid films: Analysis and numerics
(2008)In my thesis, I study coarsening processes in thin liquid films on solid substrates. The evolution of the liquid film is determined by the so-called thin film equation. Such processes are investigated in film configurations ...

Coherence effects and spectroscopy in laser driven dense atomic vapour
(2016-02-24)In this work quantum coherence effects in dense rubidium atomic vapour are investigated. Prepared in a laser driven atomic system, coherent effects, like the well-known electromagnetically induced transparency, have a ... -
Coherent sheaves with parabolic structure and construction of Hecke eigensheaves for some ramified local systems
(2003)The aim of these notes is to generalize Laumon's construction [18] of automorphic sheaves corresponding to local systems on a smooth, projective curve C to the case of local systems with indecomposable unipotent ramification ... -
Coherently driven three-level atoms in an optical cavity
(2012-02-17)We experimentally realize strong light-matter coupling of a single cesium atom to a single mode of a high-finesse optical cavity. In this regime, the optical properties of one atom change the transmission spectrum of the ... -
Cohomology of classes of symbols and classification of traces on corresponding classes of operators with non positive order
(2010-07-09)This thesis is devoted to the classification issue of traces on classical pseudo-differential operators with fixed non positive order on closed manifolds of dimension $n>1$. We describe the space of homogeneous functions ... -
Cold atom physics using ultra-thin optical fibres
(2009-01-28)In this thesis I present experiments concerning the investigation and manipulation of cold neutral atoms using ultra-thin optical fibres with a diameter smaller than the wavelength of the guided light. In such a fibre-field ... -
Collaborative Authoring of Semantically Structured Multilingual Educational Content
(2017-09-29)A major obstacle of increasing the efficiency, effectiveness and quality of education is the lack of widely available, accessible, multilingual, timely, engaging and high-quality educational material. The creation and ... -
Collaborative Integration, Publishing and Analysis of Distributed Scholarly Metadata
(2019-02-25)Research is becoming increasingly digital, interdisciplinary, and data-driven and affects different environments in addition to academia, such as industry, and government. Research output representation, publication, mining, ... -
Coloured topological operads and moduli spaces of surfaces with multiple boundary curves
(2022-07-07)While it is a classical result that the collection of moduli spaces of surfaces with a single boundary curve is anE2-algebra (more precisely: it admits an action of the little 2-cubes operad ... -
Combinatorial Solutions for Shape Optimization in Computer Vision
(2009-05-08)This thesis aims at solving so-called shape optimization problems, i.e. problems where the shape of some real-world entity is sought, by applying combinatorial algorithms. I present several advances in this field, all of ... -
Combined Weak Lensing and X-Ray Search for Galaxy Clusters and the Filaments Connecting Them
(2006)The work presented here has four main parts.
(1) A newly developed, almost fully automated data reduction pipeline for optical single- and multi-chip CCD cameras is described. Its image products are compared to those ...
