      Pok, Seokwon; Vitale, Flavia; Eichmann, Shannon L.; Benavides, Omar M.; Pasquali, Matteo; Jacot, Jeffrey G. (2014)
      The major limitation of current engineered myocardial patches for the repair of heart defects is that insulating polymeric scaffold walls hinder the transfer of electrical signals between cardiomyocytes. This loss in signal ...

      Whitford, Paul C.; Sanbonmatsu, Karissa Y.; Onuchic, José N. (2012)
      While the energy landscape theory of protein folding is now a widely accepted view for understanding how relatively-weak molecular interactions lead to rapid and cooperative protein folding, such a framework must be extended ...

      Day, Matthew; Putman, Andrew (2012)
      The Birman exact sequence describes the effect on the mapping class group of a surface with boundary of gluing discs to the boundary components. We construct an analogous exact sequence for the automorphism group of a free ...

    • Bose-Einstein Condensation of 84Sr 

      Martinez de Escobar, Y.N.; Mickelson, P.G.; Yan, M.; DeSalvo, B.J.; Nagel, S.B.; Killian, T.C. (2009)
      We report Bose-Einstein condensation of Sr84 in an optical dipole trap. Efficient laser cooling on the narrow intercombination line and an ideal s-wave scattering length allow the creation of large condensates (N0∼3×105) ...
    • Bose-Einstein condensation of 88Sr through sympathetic cooling with 87Sr 

      Mickelson, P.G.; Martinez de Escobar, Y.N.; Yan, M.; DeSalvo, B.J.; Killian, T.C. (2010-05-05)
      We report Bose-Einstein condensation of Sr88, which has a small, negative s-wave scattering length (a88=−2a0). We overcome the poor evaporative cooling characteristics of this isotope by sympathetic cooling with Sr87 atoms. ...
