      Meade, Brendan J.; Conrad, Clinton P. (Elsevier, 2008)
      Present-day orography at the Andean margin is a result of isostasy, tectonic accretion, and erosional processes. The resulting excess mass of the Andes gives rise to frictional stresses on the seismogenic plate interface ...
    • Androgen Exposure and Sensation-Seeking in Young Males 

      Campbell, Bruce C.; Gray, Peter B.; Dreber, Anna; Apicella, Carmel; Little, A.; Ellison, Peter (John Wiley & Sons, 2008)
      Testosterone is thought to be associated with short attention spans, increased novelty, and thrill seeking and behavioral disinhibition in men. However, there is little empirical evidence for such associations among normal ...

    • Aneuploidy Prediction and Tumor Classification with Heterogeneous Hidden Conditional Random Fields 

      Barutcuoglu, Zafer; Airoldi, Edoardo; Dumeaux, Vanessa; Schapire, Robert E.; Troyanskaya, Olga G. (Oxford University Press, 2008)
      Motivation: The heterogeneity of cancer cannot always be recognized by tumor morphology, but may be reflected by the underlying genetic aberrations. Array-CGH methods provide highthroughput data on genetic copy numbers, ...
    • Angels and demons in the pages of Lebor na hUidre 

      McKenna, Catherine (Colgate University Press, 2011)
    • Angiopoietin-1 Requires p190 RhoGAP to Protect against Vascular Leakage in Vivo
