    • Pacific plate deformation from horizontal thermal contraction 

      Kreemer, Corné; Gordon, Richard G. (8/15/2014)
      The central approximation of plate tectonics is that the plates are rigid, which gives the theory its rigor and predictive power. Space geodetic measurements are consistent with the rigidity of stable plate interiors, but ...
    • Imaging molecular adsorption and desorption dynamics on graphene using terahertz emission spectroscopy 

      Ajayan, P.M.; Kono, J.; Tonouchi, M. (8/13/2014)
      Being an atomically thin material, graphene is known to be extremely susceptible to its environment, including defects and phonons in the substrate on which it is placed as well as gas molecules that surround it. Thus, any ...

      Ablative treatments such as photothermal therapy (PTT) are attractive anticancer strategies because they debulk accessible tumor sites while simultaneously priming antitumor immune responses. However, the immune response ...
    • SIMS: A Hybrid Method for Rapid Conformational Analysis 

      Gipson, Bryant; Moll, Mark; Kavraki, Lydia E. (7/23/2013)
      Proteins are at the root of many biological functions, often performing complex tasks as the result of large changes in their structure. Describing the exact details of these conformational changes, however, remains a ...
    • Structural Disorder Provides Increased Adaptability for Vesicle Trafficking Pathways 

      Pietrosemoli, Natalia; Pancsa, Rita; Tompa, Peter (7/18/2013)
      Vesicle trafficking systems play essential roles in the communication between the organelles of eukaryotic cells and also between cells and their environment. Endocytosis and the late secretory route are mediated by ...
    • Competing mechanisms and scaling laws for carbon nanotube scission by ultrasonication 

      Pagani, Guido; Green, Micah J.; Poulin, Philippe; Pasquali, Matteo (7/17/2012)
      Dispersion of carbon nanotubes (CNTs) into liquids typically requires ultrasonication to exfoliate individuals CNTs from bundles. Experiments show that CNT length drops with sonication time (or energy) as a power law t?m. ...
    • Compact solar autoclave based on steam generation using broadband light-harvesting nanoparticles 

      Neumann, Oara; Feronti, Curtis; Neumann, Albert D.; Dong, Anjie; Schell, Kevin; Lu, Benjamin; Kim, Eric; Quinn, Mary; Thompson, Shea; Grady, Nathaniel; Nordlander, Peter; Oden, Maria; Halas, Naomi J. (7/16/2013)
      The lack of readily available sterilization processes for medicine and dentistry practices in the developing world is a major risk factor for the propagation of disease. Modern medical facilities in the developed world ...
    • Mechanisms of Hearing Loss after Blast Injury to the Ear 

      Cho, Sung-Il; Gao, Simon S.; Xia, Anping; Wang, Rosalie; Salles, Felipe T.; Raphael, Patrick D.; Abaya, Homer; Wachtel, Jacqueline; Baek, Jongmin; Jacobs, David; Rasband, Matthew N.; Oghalai, John S. (7/1/2013)
      Given the frequent use of improvised explosive devices (IEDs) around the world, the study of traumatic blast injuries is of increasing interest. The ear is the most common organ affected by blast injury because it is the ...
    • Combinatorial Clustering of Residue Position Subsets Predicts Inhibitor Affinity across the Human Kinome 

      Bryant, Drew H.; Moll, Mark; Finn, Paul W.; Kavraki, Lydia E. (6/6/2013)
      The protein kinases are a large family of enzymes that play fundamental roles in propagating signals within the cell. Because of the high degree of binding site similarity shared among protein kinases, designing drug ...
    • Short-term Recurrence Krylov Subspace Methods for Nearly Hermitian Matrices 

      Embree, Mark; Sifuentes, Josef A.; Soodhalter, Kirk M.; Szyld, Daniel B.; Xue, Fei (6/5/2012)
      The progressive GMRES algorithm, introduced by Beckermann and Reichel in 2008, is a residual-minimizing short-recurrence Krylov subspace method for solving a linear system in which the coefficient matrix has a low-rank ...
