    Amir, Amihood; Aumann, Yonatan; Indyk, Piotr; Levy, Avivit; Porat, Ely (Elsevier, 2009-07)
    Recently, a new pattern matching paradigm was proposed, pattern matching with address errors. In this paradigm approximate string matching problems are studied, where the content is unaltered and only the locations of the ...
  • Efficient Confocal Microscopy with a Dual-Wedge Scanner 
    Warger, William C., II; Guerrera, Stephen; Eastman, Zachary; DiMarzio, Charles A. (Society of Photo-optical Instrumentation Engineers, 2009-03)
    Confocal microscopes achieve high spatial resolution by focusing both a light source and a detector to a single point with an objective having a high numerical aperture. In order to produce an image, it is then necessary ...
  • Efficient Conservative Numerical Schemes for 1D Nonlinear Spherical Diffusion Equations with Applications in Battery Modeling 
    Zeng, Yi; Albertus, Paul; Klein, Reinhardt; Chaturvedi, Nalin; Kojic, Aleksandar; Bazant, Martin Z.; Christensen, Jake (2013-07)
    Mathematical models of batteries which make use of the intercalation of a species into a solid phase need to solve the corresponding mass transfer problem. Because solving this equation can significantly add to the ...

    Zhang, Feng; Wagner, Jeffrey C.; Platt, Randall Jeffrey; Goldfless, Stephen J.; Niles, Jacquin (Nature Publishing Group, 2014-08)
    Malaria is a major cause of global morbidity and mortality, and new strategies for treating and preventing this disease are needed. Here we show that the Streptococcus pyogenes Cas9 DNA endonuclease and single guide RNAs ...
  • Efficient crowdsourcing for multi-class labeling 
    Karger, David R.; Oh, Sewoong; Shah, Devavrat (Association for Computing Machinery (ACM), 2013-06)
    Crowdsourcing systems like Amazon's Mechanical Turk have emerged as an effective large-scale human-powered platform for performing tasks in domains such as image classification, data entry, recommendation, and proofreading. ...
