    Barnes, Rebecca T.; Gallagher, Morgan E.; Masiello, Caroline A.; Liu, Zuolin; Dugan, Brandon (2014-09-24)
    The addition of charcoal (or biochar) to soil has significant carbon sequestration and agronomic potential, making it important to determine how this potentially large anthropogenic carbon influx will alter ecosystem ...

    Ye, Qiaozhen; Guu, Tom S.Y.; Mata, Dougslas A.; Kuo, Rei-Lin; Smith, Bartram; Krug, Robert M.; Tao, Yizhi J. (2012)
    Influenza A virions contain eight ribonucleoproteins (RNPs), each comprised of a negative-strand viral RNA, the viral polymerase, and multiple nucleoproteins (NPs) that coat the viral RNA. NP oligomerization along the viral ...
  • Biocompatible Carbon Nanotube-Chitosan Scaffold Matching the Electrical Conductivity of the Heart 

    Pok, Seokwon; Vitale, Flavia; Eichmann, Shannon L.; Benavides, Omar M.; Pasquali, Matteo; Jacot, Jeffrey G. (2014-09-18)
    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 ...
  • Biodiversity maintenance in food webs with regulatory environmental feedbacks 

    Rauscher, Daniel; Brown, Christopher G; Dunham, Amy E; Bagdassarian, Carey K (2007)
    Although the food web is one of the most fundamental and oldest concepts in ecology, elucidating the strategies and structures by which natural communities of species persist remains a challenge to empirical and theoretical ...
  • Biomedical applications of plasmon resonant metal nanoparticles

  • Biomolecular dynamics: order–disorder transitions and energy landscapes 

    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 ...
  • A Birman exact sequence for Aut(Fn) 

    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 ...
  • Bismuth@US-tubes as a potential contrast agent for X-ray imaging applications 

    Rivera, Eladio J.; Tran, Lesa A.; Hernández-Rivera, Mayra; Yoon, Diana; Mikos, Antonios G.; Rusakova, Irene A.; Cheong, Benjamin Y.; Cabreira-Hansen, Maria da Graça; Willerson, James T.; Perin, Emerson C.; Wilson, Lon J. (2013)
    The encapsulation of bismuth as BiOCl/Bi2O3 within ultra-short (ca. 50 nm) single-walled carbon nanocapsules (US-tubes) has been achieved. The Bi@US-tubes have been characterized by high-resolution transmission electron ...
  • Blind Test of Methods for Obtaining 2-D Near-Surface Seismic Velocity Models from First-Arrival Traveltimes

  • Bose-Einstein Condensation of 84Sr 

    Martinez de Escobar, Y.N.; Mickelson, P.G.; Yan, M.; DeSalvo, B.J.; Nagel, S.B.; Killian, T.C. (2009-11-09)
    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) ...
