      The cBioPortal for Cancer Genomics is an open-source software platform that enables interactive, exploratory analysis of large-scale cancer genomics data sets with a user-friendly interface. It integrates genomic and ...

    • Abstract metaprolog engine 

      Cicekli, I. (Elsevier, 1998)
      A compiler-based meta-level system for MetaProlog language is presented. Since MetaProlog is a meta-level extension of Prolog, the Warren Abstract Machine (WAM) is extended to get an efficient implementation of meta-level ...

    • Accelerating genome analysis: a primer on an ongoing journey 

      Alser, M.; Zülal, Bingöl; Cali, D. S.; Kim, J.; Ghose, S.; Alkan, Can; Mutlu, Onur (IEEE, 2020)
