  • Baker, Matthew L.; Hryc, Corey F.; Zhang, Qinfen; Wu, Weimin; Jakana, Joanita; Haase-Pettingell, Cameron; Afonine, Pavel V.; Adams, Paul D.; King, Jonathan Alan; Jiang, Wen; Chiu, Wah (National Academy of Sciences (U.S.), 2013-07)
    High-resolution structures of viruses have made important contributions to modern structural biology. Bacteriophages, the most diverse and abundant organisms on earth, replicate and infect all bacteria and archaea, making ...
  • Itzkovitz, Shaul Shalev; van Oudenaarden, Alexander (Nature Publishing Group, 2011-03)
    High-throughput gene expression screens provide a quantitative picture of the average expression signature of biological samples. However, the analysis of spatial gene expression patterns with single-cell resolution requires ...
  • Wei, Jun; Rizzoli, Paola M. (Springer, 2009-12)
    The effectiveness of an ensemble Kalman filter (EnKF) is assessed in the Selat Pauh of Singapore using observing system simulation experiment. Perfect model experiments are first considered. The perfect model experiments ...
  • Yeang, Chen-Hsiang, 1969-; Mak, Craig; McCuine, Scott; Workman, Christopher; Ideker, Trey; Jaakkola, Tommi S. (BioMed Central Ltd, 2005-07)
    As genome-scale measurements lead to increasingly complex models of gene regulation, systematic approaches are needed to validate and refine these models. Towards this goal, we describe an automated procedure for prioritizing ...
  • Hirschman, Gordon B.; Rosbury, Tamara S.; Armoundas, Antonis A.; Galea, Anna M.; Choppy, Kristen J.; Barley, Maya E.; Cohen, Richard J. (Institute of Electrical and Electronics Engineers, 2009-04)
    Accurate guidance of an ablation catheter is critical in the RF ablation (RFA) of ventricular tachycardia (VT). With current technologies, it is challenging to rapidly and accurately localize the site of origin of an ...
  • McCarthy, K. A.; Leman, S. W.; Anderson, A.; Brandt, D.; Brink, P. L.; Cabrera, B.; Cherry, M.; Couto E Silva, E.; Cushman, P.; Doughty, T.; Figueroa-Feliciano, E.; Tomada, A.; Figueroa-Feliciano, Enectalí; Kim, P.; Mirabolfathi, N.; Novak, L.; Partridge, R.; Pyle, M.; Reisetter, A.; Resch, R.; Sadoulet, B.; Serfass, B.; Sundqvist, K. M.; Tomada, A. (Springer-Verlag, 2012-01)
    The SuperCDMS collaboration is a dark matter search effort aimed at detecting the scattering of WIMP dark matter from nuclei in cryogenic germanium targets. The CDMS Detector Monte Carlo (CDMS-DMC) is a simulation tool ...
  • Unglert, Carolin I.; Warger, William C.; Namati, Eman; Hostens, Jeroen; Birngruber, Reginald; Bouma, Brett E.; Tearney, Guillermo J. (SPIE, 2012-12)
    Optical coherence tomography (OCT) has been increasingly used for imaging pulmonary alveoli. Only a few studies, however, have quantified individual alveolar areas, and the validity of alveolar volumes represented within ...
  • Lucas, Deborah J. (Annual Reviews, 2012-01)
    Governments play a central role in the allocation of capital and risk in the economy. Evaluating the cost to taxpayers of government investments requires an assumption about the government’s cost of capital. Governments ...
  • Dahleh, Munther A.; Kolmanovsky, Ilya; Rinehart, Michael David (Institute of Electrical and Electronics Engineers, 2009-06)
    In this note, we prove that dynamic programming value iteration converges uniformly for discrete-time homogeneous systems and continuous-time switched homogeneous systems. For discrete-time homogeneous systems, rather than ...
  • Tay, Wee Peng; Tsitsiklis, John N. (Institute of Electrical and Electronics Engineers (IEEE), 2011-04)
    We consider the decentralized binary hypothesis testing problem in networks with feedback, where some or all of the sensors have access to compressed summaries of other sensors' observations. We study certain two-message ...
  • Rigby, Matthew; Manning, A. J.; Prinn, Ronald G. (American Geophysical Union, 2012-06)
    We present an observing system simulation experiment examining the potential benefits of new methane isotopologues measurements for global- and national-scale source and sink inversions. New measurements are expected in ...
  • Mu, Beipeng; Chowdhary, Girish; How, Jonathan P. (SPIE, 2013-05)
    This paper discusses the problem of robust allocation of unmanned vehicles (T.N) to targets with uncertainties. In particular, the team consists of heterogeneous vehicles with different exploration and exploitation abilities. ...
  • Morgado, Frederico; Nagaralu, Sai Suresh; Macario, Rosario; de Neufville, Richard (European Regional Science Association, 2011-09)
    Investments decisions for airport capacity expansion are usually taken, either when demand exceeds the current capacity and the airport is working under congestion, or when current demand is expected to overcome current ...
  • van Oudenaarden, Alexander; Rifkin, Scott A.; Raj, Arjun; Andersen, Erik (Nature Publishing Group, 2010-02)
    The phenotypic differences between individual organisms can often be ascribed to underlying genetic and environmental variation. However, even genetically identical organisms in homogeneous environments vary, indicating ...
  • Perfors, Amy; Tenenbaum, Joshua B.; Wonnacott, Elizabeth (Cambridge University Press, 2010-04)
    We present a hierarchical Bayesian framework for modeling the acquisition of verb argument constructions. It embodies a domain-general approach to learning higher-level knowledge in the form of inductive constraints (or ...
  • Chatterjee, A.; Harth, C. M.; Salameh, P. K.; Manning, A. J.; Hall, B. D.; Mühle, J.; Weiss, R. F.; O'Doherty, S.; Young, D.; Ganesan, Anita Lakshmi; Prinn, Ronald G.; Meredith, Laura Kelsey (Copernicus GmbH, 2013-11)
    High-frequency atmospheric measurements of methane (CH[subscript 4]), nitrous oxide (N[subscript 2]O) and sulfur hexafluoride (SF[subscript 6]) from Darjeeling, India are presented from December 2011 (CH[subscript 4])/March ...
  • Wunsch, Carl (Elsevier B.V., 2010-08)
    The ECCO–GODAE global estimate of the ocean circulation 1992–2007 is analyzed in the region of the Indonesian Throughflow (ITF), including the Southern Ocean flow south of Australia. General characteristics are an intense ...
  • Celik, Guner Dincer; Borst, S.; Whiting, P.; Modiano, Eytan H. (Institute of Electrical and Electronics Engineers, 2011-07)
    This paper considers the scheduling problem for networks with interference constraints and switchover delays, where it takes a nonzero time to reconfigure each service schedule. Switchover delay occurs in many telecommunication ...
  • Secord, Thomas William; Asada, Harry (Institute of Electrical and Electronics Engineers (IEEE), 2010-12)
    A new approach to a variable stiffness actuator with tunable resonant frequencies is presented in this paper. Variable stiffness actuators have become increasingly important to meet safety requirements and achieve adaptive ...
  • Secord, Thomas William; Asada, Harry (Institute of Electrical and Electronics Engineers, 2009-07)
    A simple and efficient approach for varying the inherent stiffness and impedance of a muscle-like actuator is presented. The basic architecture of PZT cellular actuators has already achieved a large effective strain (10-20%). ...
