    Uncertainty visualization : concepts, methods, and applications in biological data visualization
    (2022) Weiskopf, Daniel
    This paper provides an overview of uncertainty visualization in general, along with specific examples of applications in bioinformatics. Starting from a processing and interaction pipeline of visualization, components are discussed that are relevant for handling and visualizing uncertainty introduced with the original data and at later stages in the pipeline, which shows the importance of making the stages of the pipeline aware of uncertainty and allowing them to propagate uncertainty. We detail concepts and methods for visual mappings of uncertainty, distinguishing between explicit and implict representations of distributions, different ways to show summary statistics, and combined or hybrid visualizations. The basic concepts are illustrated for several examples of graph visualization under uncertainty. Finally, this review paper discusses implications for the visualization of biological data and future research directions.

    Verfahren zur Bestimmung der alkalischen Phosphatase-Aktivität
    (1991) Osipov, A. P.; Gapanova, N. K.; Egorov, A. M.; Berezin, I. V.; Pertschi, Ottmar (Übersetzer)
    The activity of alk. phosphatase is detd. by incubation of a sample with NADP (I) in a buffer medium with subsequent spectrophotometric recording of the hydrolysis product in an enzymic regeneration system of a cofactor-contg. alk. dehydrogenase and two substrates, one of which is EtOH. The sensitivity of the detn. is increased and a rapid and simplified detn. is ensured by incubation of the sample and recording of the hydrolysis product catalyzed by alk. phosphatase in a pH 8,5 - 9,1 tris-HCl buffer; By using I in reduced form at 10-7 - 10-4 M; by using horse liver alk. dehydrogenase at 5 x 10-7 - 10-5 M the cofactor regeneration system; by using p-nitroso-N,N'-dimethylamine at 5 x 10-6 - 3 x 10-4 M as th 2nd substrate; and by adding salicyclic acid amide to 2 x 10-4 - 5 x 10-7 M and Na orthophosphate to 0,05 M to the system.

    Über die hydrodynamischen Kennwerte des Flossenvortriebs bei Delfinen
    (2005) Kajan, V. P.; Ludwig, Sören (Übersetzerin)
    Die hydrodynamische Untersuchung des schnellen Schwimmens von Wassertieren ist für Forscher, die auf dem Gebiet der Hydrobionik arbeiten, von großem Interesse. Besondere Beachtung finden dabei Tiere (insbesondere Delfine), die sich mit Hilfe von Biegungs-Schwingungs-Bewegungen der Schwanzflosse, ähnlich dem Flügelschlag, fortbewegen.
