Its objective is to catalogue data that will improve our understanding of changes in the geomagnetic field, physical environments, and climate. Findings: GEOMAGIA50.v3 for sediments builds upon the structure of the pre-existing GEOMAGIA50 database for magnetic data from archeological and volcanic materials. A strong emphasis has been placed on the storage of geochronological data, and it is the first magnetic archive that includes comprehensive radiocarbon age data from sediments. The database will be updated as new sediment data become available. Conclusions: The web-based interface for the sediment database is located at http://geomagia.gfz-potsdam.de/geomagiav3/SDquery.php. This paper is a companion to Brown et al. (Earth Planets Space doi:10.1186/s40623-015-0232-0,2015) and describes the data types, structure, and functionality of the sediment database.}, language = {en} } @misc{BreuningerLenhard2017, author = {Breuninger, Holger and Lenhard, Michael}, title = {Expression of the central growth regulator BIG BROTHER is regulated by multiple cis-elements}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-400971}, pages = {10}, year = {2017}, abstract = {Background Much of the organismal variation we observe in nature is due to differences in organ size. The observation that even closely related species can show large, stably inherited differences in organ size indicates a strong genetic component to the control of organ size. Despite recent progress in identifying factors controlling organ growth in plants, our overall understanding of this process remains limited, partly because the individual factors have not yet been connected into larger regulatory pathways or networks. To begin addressing this aim, we have studied the upstream regulation of expression of BIG BROTHER (BB), a central growth-control gene in Arabidopsis thaliana that prevents overgrowth of organs. Final organ size and BB expression levels are tightly correlated, implying the need for precise control of its expression. BB expression mirrors proliferative activity, yet the gene functions to limit proliferation, suggesting that it acts in an incoherent feedforward loop downstream of growth activators to prevent over-proliferation. Results To investigate the upstream regulation of BB we combined a promoter deletion analysis with a phylogenetic footprinting approach. We were able to narrow down important, highly conserved, cis-regulatory elements within the BB promoter. Promoter sequences of other Brassicaceae species were able to partially complement the A. thaliana bb-1 mutant, suggesting that at least within the Brassicaceae family the regulatory pathways are conserved. Conclusions This work underlines the complexity involved in precise quantitative control of gene expression and lays the foundation for identifying important upstream regulators that determine BB expression levels and thus final organ size.}, language = {en} } @misc{Kunde2013, type = {Master Thesis}, author = {Kunde, Felix}, title = {CityGML in PostGIS : Portierung, Anwendung und Performanz-Analyse am Beipiel der 3D City Database von Berlin}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-63656}, school = {Universit{\"a}t Potsdam}, year = {2013}, abstract = {Der internationale Standard CityGML ist zu einer zentralen Schnittstelle f{\"u}r die geometrische wie semantische Beschreibung von 3D-Stadtmodellen geworden.

PostGIS gilt als eine der ausgereiftesten Geodatenbanken und wurde in diesem Jahr mit dem Release der Version 2.0 nochmals um zahlreiche Funktionen und Features (u.a. auch 3D-Unterst{\"u}tzung) erweitert.
