  • A comparative analysis of ceramic and cemented carbide end mills 
    Dröder, Klaus; Karpuschewski, Bernhard; Uhlmann, Eckart; Arrabiyeh, Peter A.; Berger, Daniel; Busemann, Sarah; Hartig, Jörg; Madanchi, Nadine; Mahlfeld, Georg; Sommerfeld, Christian (Berlin : Springer, 2020)
    Milling of ferrous metals is usually performed by applying cemented carbide tools due to their high hardness, temperature and wear resistance. Recently, ceramic tool materials have been on the rise and enhanced the efficiency ...
  • A comparison of curated gene sets versus transcriptomics-derived gene signatures for detecting pathway activation in immune cells 
    Liu, Bin; Lindner, Patrick; Jirmo, Adan Chari; Maus, Ulrich; Illig, Thomas; Deluca, David S. (London : BioMed Central, 2020)
    Background: Despite the significant contribution of transcriptomics to the fields of biological and biomedical research, interpreting long lists of significantly differentially expressed genes remains a challenging step ...
  • A comprehensive quality assessment framework for scientific events 
    Vahdati, Sahar; Fathalla, Said; Lange, Christoph; Behrend, Andreas; Say, Aysegul; Say, Zeynep; Auer, Sören (Dordrecht [u.a.] : Springer Science + Business Media B.V., 2020)
    Systematic assessment of scientific events has become increasingly important for research communities. A range of metrics (e.g., citations, h-index) have been developed by different research communities to make such ...
  • A comprehensive video codec comparison 
    Laude, Thorsten; Adhisantoso, Yeremia Gunawa; Voges, Jan; Munderloh, Marco; Ostermann, Jörn (Cambridge : Cambridge Univ. Press, 2019)
    In this paper, we compare the video codecs AV1 (version 1.0.0-2242 from August 2019), HEVC (HM and x265), AVC (x264), the exploration software JEM which is based on HEVC, and the VVC (successor of HEVC) test model VTM ...
  • A computational model for previtamin D 3 production in skin 
    Meinhardt-Wollweber, Merve; Krebs, Ronald (Cambridge : Royal Society of Chemistry, 2012)
    Low levels of vitamin D have been implicated in a wide variety of health issues from calcemic diseases to cancer, diabetes and cardiovascular disease. For most humans, the majority of vitamin D 3 is derived from sunlight. ...
