      Tumors are heterogeneous tissues consisting of multiple regions with distinct characteristics. Characterization of these intra-tumor regions can improve patient diagnosis and enable a better targeted treatment. Ideally, ...
    • Perfopticon: Visual Query Analysis for Distributed Databases 

      Moritz, Dominik; Halperin, Daniel; Howe, Bill; Heer, Jeffrey (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      Distributed database performance is often unpredictable due to issues such as system complexity, network congestion, or imbalanced data distribution. These issues are difficult for users to assess in part due to the opaque ...
    • MoleCollar and Tunnel Heat Map Visualizations for Conveying Spatio-Temporo-Chemical Properties Across and Along Protein Voids
