New Insights into the Milky Way Magnetic Fields through Radio Broadband Spectro-polarimetry
Ma, Yik Ki (2020-03-05)Magnetic field is an essential ingredient of the interstellar medium of galaxies. In particular, an accurate characterisation of the magnetic field strength and structure of the Milky Way is crucial for complete understanding ... -
A new methodology to use color spectral data for taxonomic, phylogenetic, and biogeographic studies: An example with three genera of lowland hummingbirds: Topaza, Anthracothorax, and Eulampis
Schmitz Ornés, Angela (2005)I developed a methodology to obtain and compare integral information on bird plumage coloration, using color spectral data to conduct studies on geographic variation, taxonomy and phylogeny of different bird groups. I used ... -
A new molecular mechanism to promote protean agonism at a G protein-coupled receptorl
De Min, Anna (2017-07-24)Protean agonists are of great pharmacological interest as their apparent efficacy may change in magnitude and direction depending on the constitutive activity of a receptor. Yet, this intriguing phenomenon has been poorly ... -
New Results on Abstract Voronoi Diagrams
Bohler, Cecilia (2015-07-21)Voronoi diagrams are a fundamental structure used in many areas of science. For a given set of objects, called sites, the Voronoi diagram separates the plane into regions, such that points belonging to the same region have ... -
New Results on the Probabilistic Analysis of Online Bin Packing and its Variants
Fischer, Carsten Oliver (2019-12-03)The classical bin packing problem can be stated as follows: We are given a multiset of items {a<sub>1</sub>, ..., a<sub>n</sub>} with sizes in [0,1], and want to pack them into a minimum number of bins, each of which with ... -
Next-Generation Electronics for the Read-Out of Micro-Pattern Gaseous Detectors
Scharenberg, Lucian Simon (2023-04-20)Developed by the RD51 collaboration, the Scalable Readout System (SRS) is widely used for the read-out of Micro-Pattern Gaseous Detectors (MPGDs). With different front-end Application-Specific Integrated Circuits (ASICs) ... -
Next-generation phenotyping for rare Mendelian disorders
Hsieh, Tzung-Chien (2022-08-31)Worldwide, rare genetic disorders affect more than 6.2% of the population. The long diagnostic process is often called the ‘diagnostic odyssey.’ With the recent advances in computer vision, many next-generation phenotyping ... -
NHC-supported Disilavinylidenes and Oxysilylenes: Synthesis, Characterization and Reactivity Studies
Schwarzwald, Simon (2023-07-06)Vinylidenes (:C=CR2) are a transient subclass of carbenes and readily isomerize to the respective alkynes (R C≡C R). While stabilization by metal coordination is possible, their instability is commonly utilized in the Corey ... -
Nicht symmetrische Graphenmoleküle mittels [3+2+1]-Benzanellierung und Untersuchungen von haptotropen Wanderungen auf Oberflächen
Rang, Carola Monika (2010-03-02)Im Rahmen dieser Arbeit wird ein potentieller Zugang zu nicht- symmetrischen Graphenmolekülen via [3+2+1]-Benzanellierung und anschließender oxidativer Cyclodehydrierung der synthetisierten Oligoarylarene untersucht. Der ... -
Nichtlineare Anregungen und Ladungstransport in Lithiumniobatkristallen untersucht mit Femtosekunden-Lichtgittern
Maxein, Karl Dominik (2010-03-04)Lithiumniobat-Kristalle (LiNbO<sub>3</sub>) werden oftmals als Material in der nichtlinearen Optik und Photonik eingesetzt. Sie weisen allerdings den photorefraktiven Effekt auf, der Strahlprofil und Phasenanpassung zerstören ... -
Niedermolekulare metallorganische Gelatoren: Desoxyaminozucker-Carbenkomplexe und Cholesterol-Titanocene
Klawonn, Thorsten Harald (2008)<p>Im Rahmen dieser Arbeit konnte das Gebiet der niedermolekularen metallorganischen Gelatoren auf zur Gelierung befähigte Aminozucker- funktionalisierte Carbenkomplexe sowie Metallocene ausgedehnt werden. Mittels ... -
Niederschlagsbestimmung aus METEOSAT-Second Generation-Zeitreihendaten mit dem Methodenverbund ORFEUSS: Fallbeispiel Namibia
Welle, Torsten (2009-10-28)Der Niederschlag ist eines der wichtigsten Parameter im Klimasystem der Erde und bestimmt auf vielfältige Weise unser Leben. Das Wissen über die raumzeitliche Verteilung von Niederschlagsmengen spielt deshalb eine bedeutende ... -
