The purpose of this study is the head-to-head intra-individual comparison of \(^{68}\)Ga-FAPI versus standard-of-care \(^{18}\)F-FDG in PET/CT in organ biodistribution and tumor uptake in patients with various cancers. Material and Methods This international retrospective multicenter analysis included PET/CT data from 71 patients from 6 centers who underwent both \(^{68}\)Ga-FAPI and \(^{18}\)F-FDG PET/CT within a median time interval of 10 days (range 1-89 days). Volumes of interest (VOIs) were manually drawn in normal organs and tumor lesions to quantify tracer uptake by SUVmax and SUVmean. Furthermore, tumor-to-background ratios (TBR) were generated (SUVmax tumor/ SUVmax organ). Results A total of 71 patients were studied of, which 28 were female and 43 male (median age 60). In 41 of 71 patients, the primary tumor was present. Forty-three of 71 patients exhibited 162 metastatic lesions. \(^{68}\)Ga-FAPI uptake in primary tumors and metastases was comparable to 18F-FDG in most cases. The SUVmax was significantly lower for \(^{68}\)Ga-FAPI than \(^{18}\)F-FDG in background tissues such as the brain, oral mucosa, myocardium, blood pool, liver, pancreas, and colon. Thus, \(^{68}\)Ga-FAPI TBRs were significantly higher than 18F-FDG TBRs in some sites, including liver and bone metastases. Conclusion Quantitative tumor uptake is comparable between \(^{68}\)Ga-FAPI and \(^{18}\)F-FDG, but lower background uptake in most normal organs results in equal or higher TBRs for \(^{68}\)Ga-FAPI. Thus, \(^{68}\)Ga-FAPI PET/CT may yield improved diagnostic information in various cancers and especially in tumor locations with high physiological \(^{18}\)F-FDG uptake.}, language = {en} } @article{HudsonNewboldContuetal.2014, author = {Hudson, Lawrence N. and Newbold, Tim and Contu, Sara and Hill, Samantha L.

Existing global databases of species' threat status or population time series are dominated by charismatic species. The collation of datasets with broad taxonomic and biogeographic extents, and that support computation of a range of biodiversity indicators, is necessary to enable better understanding of historical declines and to project - and avert - future declines. We describe and assess a new database of more than 1.6 million samples from 78 countries representing over 28,000 species, collated from existing spatial comparisons of local-scale biodiversity exposed to different intensities and types of anthropogenic pressures, from terrestrial sites around the world. The database contains measurements taken in 208 (of 814) ecoregions, 13 (of 14) biomes, 25 (of 35) biodiversity hotspots and 16 (of 17) megadiverse countries. The database contains more than 1\% of the total number of all species described, and more than 1\% of the described species within many taxonomic groups - including flowering plants, gymnosperms, birds, mammals, reptiles, amphibians, beetles, lepidopterans and hymenopterans. The dataset, which is still being added to, is therefore already considerably larger and more representative than those used by previous quantitative models of biodiversity trends and responses. The database is being assembled as part of the PREDICTS project (Projecting Responses of Ecological Diversity In Changing Terrestrial Systems - ). We make site-level summary data available alongside this article. The full database will be publicly available in 2015.}, language = {en} } @phdthesis{Kessler2000, author = {Keßler, Manuel}, title = {Die Ladyzhenskaya-Konstante in der numerischen Behandlung von Str{\"o}mungsproblemen}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-2791}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2000}, abstract = {Charakteristisch f{\"u}r die L{\"o}sbarkeit von elliptischen partiellen Differentialgleichungssystemen mit Nebenbedingungen ist das Auftreten einer inf-sup-Bedingung. Im prototypischen Fall der Stokes-Gleichungen ist diese auch als Ladyzhenskaya-Bedingung bekannt. Die G{\"u}ltigkeit dieser Bedingung, bzw. die Existenz der zugeh{\"o}rigen Konstante ist eine Eigenschaft des Gebietes, innerhalb dessen die Differentialgleichung gel{\"o}st werden soll. W{\"a}hrend die Existenz schon die L{\"o}sbarkeit garantiert, ist beispielsweise f{\"u}r Fehleraussagen bei der numerischen Approximation auch die Gr{\"o}ße der Konstanten sehr wichtig. Insbesondere auch deshalb, weil eine {\"a}hnliche inf-sup-Bedingung auch bei der Diskretisierung mittel Finiter-Elemente-Methoden auftaucht, die hier Babuska-Brezzi-Bedingung heißt. Die Arbeit befaßt sich auf der einen Seite mit einer analytischen Absch{\"a}tzung der Ladyzhenskaya-Konstante f{\"u}r verschiedene Gebiete, wobei {\"A}quivalenzen mit verwandten Problemen aus der komplexen Analysis (Friedrichs-Ungleichung) und der Strukturmechanik (Kornsche Ungleichung) benutzt werden. Ein weiterer Teil befaßt sich mit dem Zusammenhang zwischen kontinuierlicher Ladyzhenskaya- Konstante und diskreter Babuska-Brezzi-Konstante. Die dabei gefundenen Ergebnisse werden mit Hilfe eines dazu entwickelten leistungsf{\"a}higen Finite-Elemente-Programmsystems numerisch verifiziert. Damit k{\"o}nnen erstmals genaue Absch{\"a}tzungen der Konstanten in zwei und drei Dimensionen gefunden werden. Aufbauend auf diesen Resultaten wird ein schneller L{\"o}sungsalgorithmus f{\"u}r die Stokes-Gleichungen vorgeschlagen und anhand von problematischen Gebieten dessen {\"U}berlegenheit gegen{\"u}ber klassischen Verfahren wie beispielsweise der Uzawa-Iteration demonstriert. W{\"a}hrend selbst bei einfachen Geometrien eine Konvergenzbeschleunigung um einen Faktor 5 erwartet werden kann, sind in kritischen F{\"a}llen Faktoren bis zu 1000 m{\"o}glich.}, subject = {Stokes-Gleichung}, language = {de} }
