      The Neoproterozoic was an era of great environmental and biological change, but a paucity of direct and precise age constraints on strata from this time has prevented the complete integration of these records. We present ...
    • Calibrating the Galaxy Halo–Black Hole Relation Based on the Clustering of Quasars 

      Wyithe, J. Stuart B.; Loeb, Abraham (American Astronomical Society, 2005)
      The observed number counts of quasars can be explained either by long-lived activity within rare massive hosts or by short-lived activity within smaller, more common hosts. It has been argued that quasar lifetimes can ...

    • Calibration Procedures for a Computational Model of Ductile Fracture 

      Xue, Z; Pontin, M. G.; Zok, F. W.; Hutchinson, John W. (Elsevier, 2010)
      A recent extension of the Gurson constitutive model of damage and failure of ductile structural alloys accounts for localization and crack formation under shearing as well as tension. When properly calibrated against a ...
    • A call for collaborative interfaces 

      Shieber, Stuart (Association for Computing Machinery, 1996)
      In this note, I call for a move towards viewing interfaces as means for people and computers to collaborate on solving problems rather than means for people to control computers. This collaborative perspective on user ...
