  • Hughes, Scott A.; Lang, Ryan N.; Cornish, Neil J. (American Physical Society, 2011-07)
    The future space-based gravitational wave detector LISA will be able to measure parameters of coalescing massive black hole binaries, often to extremely high accuracy. Previous work has demonstrated that the black hole ...
  • Bertsimas, Dimitris J.; Czerwinski, David; Kane, Michael A. (Springer, 2013-02)
    We present a methodology for using health insurance claims data to monitor quality of care. The method uses a statistical model trained on the quality ratings of a medical expert. In a pilot study, the expert rated the ...
  • Grover, William; Bryan, Andrea Kristine; Diez Silva, Monica; Suresh, Subra; Higgins, John M.; Manalis, Scott R. (National Academy of Sciences (U.S.), 2011-07)
    We have used a microfluidic mass sensor to measure the density of single living cells. By weighing each cell in two fluids of different densities, our technique measures the single-cell mass, volume, and density of ...
  • Cantillon-Murphy, Pádraig; Wald, Lawrence L.; Zahn, Markus; Adalsteinsson, Elfar (Wiley Blackwell (John Wiley & Sons), 2009-07)
    Traditional methods of measuring magnetization in magnetic fluid samples, such as vibrating sample magnetometry (VSM), are typically limited to maximum field strengths of about 1 T. This work demonstrates the ability of ...

  • Lee, Young-Jin; Palazzo, David J.; Warnakulasooriya, Rasil; Pritchard, David E. (American Physical Society, 2008-01)
    We investigate short-term learning from hints and feedback in a Web-based physics tutoring system. Both the skill of students and the difficulty and discrimination of items were determined by applying item response theory ...
  • Monie, Dileep D.; Glieberman, Aaron L.; de Mora, Kim; Czar, Michael J.; Cumbers, John; Ajo-Franklin, Caroline M.; Davis, Joseph Harry; Rubin, Adam J.; Kelly, Jason R.; Endy, Andrew D. (BioMed Central, 2009-03)
    Background: The engineering of many-component, synthetic biological systems is being made easier by the development of collections of reusable, standard biological parts. However, the complexity of biology makes it difficult ...
  • Cebrian, Manuel; Lahiri, Mayank; Oliver, Nuria; Pentland, Alex Paul (Institute of Electrical and Electronics Engineers, 2010-08)
    In any society, is the way in which individuals interact, intentionally or unintentionally, designed to maximize global benefit, or does it result in a fundamentally non-egalitarian stratification of society, where a small ...
  • Townsend, Robert; Urzula, Sergio S. (Cambridge University Press, 2009-09)
    We study the impact that financial intermediation can have on productivity through the alleviation of credit constraints in occupation choice and/or an improved allocation of risk, using both static and dynamic structural ...
  • Reis, Ben I.; Brownstein, John S. (Springer (Biomed Central Ltd.), 2010-08)
    Background Internet search patterns have emerged as a novel data source for monitoring infectious disease trends. We propose that these data can also be used more broadly to study the impact of health policies across ...
  • Vitale, Salvatore; Veitch, John; Raymond, Vivien; Sturani, Riccardo; Lynch, Ryan Christopher (American Physical Society, 2014-06)
    Compact binary coalescences are the most promising sources of gravitational waves (GWs) for ground-based detectors. Binary systems containing one or two spinning black holes are particularly interesting due to spin-orbit ...
  • Adalgeirsson, Sigurdur Orn; Breazeal, Cynthia Lynn (Institute of Electrical and Electronics Engineers, 2010-03)
    Telepresence refers to a set of technologies that allow users to feel present at a distant location; telerobotics is a subfield of telepresence. This paper presents the design and evaluation of a telepresence robot which ...
  • Randell, John C.W.; Fan, Andy; Chan, Clara; Francis, Laura I.; Heller, Ryan C.; Bell, Stephen P.; Galani, Kyriakitsa (Elsevier, 2010-11)
    Activation of the eukaryotic replicative DNA helicase, the Mcm2-7 complex, requires phosphorylation by Cdc7/Dbf4 (Dbf4-dependent kinase or DDK), which, in turn, depends on prior phosphorylation of Mcm2-7 by an unknown ...
  • Tse, Janet M.; Cheng, Gang; Tyrrell, James A.; Wilcox-Adelman, Sarah A.; Boucher, Yves; Jain, Rakesh K.; Munn, Lance L. (National Academy of Sciences, 2012-01)
    Uncontrolled growth in a confined space generates mechanical compressive stress within tumors, but little is known about how such stress affects tumor cell behavior. Here we show that compressive stress stimulates migration ...
  • Ovchinnikov, Victor; Trout, Bernhardt L.; Karplus, Martin (Elsevier B.V., 2009-10)
    Myosin motor function depends on the interaction between different domains that transmit information from one part of the molecule to another. The interdomain coupling in myosin V is studied with restrained targeted molecular ...
  • Esser, Birgit; Mirica, Katherine; Weis, Jonathan Garrett; Schnorr, Jan Markus; Swager, Timothy Manning (Wiley Blackwell, 2012-10)
    Pencil it in: Mechanical abrasion of compressed single-walled carbon nanotubes (SWCNTs) on the surface of paper produces sensors capable of detecting NH[subscript 3] gas at sub-ppm concentrations. This method of fabrication ...
  • Chen, Di; Kuru, Yener; Stefanik, Todd; Tuller, Harry L.; Bishop, Sean; Kim, Jae Jin; Thompson, Nicholas J. (The Electrochemical Society, 2011-05)
    Praseodymium doped cerium oxide (PCO) shows mixed ionic and electronic conducting (MIEC) characteristics at relatively high pO2 (e.g. air) and enhanced oxygen storage capacity (OSC), of interest for solid oxide fuel cell ...
  • Xu, Zhiping; Buehler, Markus J. (American Physical Society, 2010-06)
    Mechanical properties of structural protein materials are crucial for our understanding of biological processes and disease states. Through utilization of molecular simulation based on stress wave tracking, we investigate ...
  • Brigham, Mark D.; Bick, Alexander G.; Lo, Edward; Bendali, Amel; Burdick, Jason A.; Khademhosseini, Ali (Mary Ann Liebert, Inc., 2009-07)
    In this work, we present a class of hydrogels that leverage the favorable properties of the photo-cross-linkable hyaluronic acid (HA) and semi-interpenetrating collagen components. The mechanical properties of the ...
  • Buell, Sezen; Van Vliet, Krystyn J.; Rutledge, Gregory C. (American Chemical Society, 2009-06)
    The extent to which the intrinsic mechanical properties of polymer fibers depend on physical size has been a matter of dispute that is relevant to most nanofiber applications. Here, we report the elastic and plastic ...
