  • Weisenfeld, Neil I; Yin, Shuangye; Sharpe, Ted; Lau, Bayo; Hegarty, Ryan; Holmes, Laurie; Sogoloff, Brian; Tabbaa, Diana; Williams, Louise; Russ, Carsten; Nusbaum, Chad; MacCallum, Iain; Jaffe, David B.; Lander, Eric S. (Nature Publishing Group, 2014-10)
    Complete knowledge of the genetic variation in individual human genomes is a crucial foundation for understanding the etiology of disease. Genetic variation is typically characterized by sequencing individual genomes and ...
  • Mineo, S.; Pooley, D.; Rappaport, Saul A.; Levine, Alan M.; Homan, Jeroen; Steinhorn, Benjamin S. (IOP Publishing, 2014-12)
    We present a comprehensive study of the total X-ray emission from the colliding galaxy pair NGC 2207/IC 2163, based on Chandra, Spitzer, and GALEX data. We detect 28 ultraluminous X-ray sources (ULXs), 7 of which were not ...
  • Belanger-Rioux, R.; Demanet, Laurent (Society for Industrial and Applied Mathematics, 2015-10)
    Absorbing layers are sometimes required to be impractically thick in order to offer an accurate approximation of an absorbing boundary condition for the Helmholtz equation in a heterogeneous medium. It is always possible ...
  • Choi, Jae-Hoon; Christensen, Caleb A.; Heo, Myoung-Sun; Ketterle, Wolfgang; Lee, Ye-Ryoung; Rvachov, Timur Michael; Wang, Tout T. (American Physical Society, 2012-06)
    Fermi gases with repulsive interactions are characterized by measuring their compressibility as a function of interaction strength. The compressibility is obtained from in-trap density distributions monitored by phase-contrast ...
  • Choong, Looh Tchuin; Mannarino, Matthew M.; Basu, Sandip; Rutledge, Gregory C. (Springer-Verlag, 2013-06)
    Compressive properties of electrospun fiber mats are reported for the first time. Mats of bisphenol-A polysulfone (PSU) and of poly(trimethyl hexamethylene terephthalamide) [PA 6(3)T] were electrospun and annealed over a ...
  • Magesan, Easwar; Cappellaro, Paola; Cooper-Roy, Alexandre (American Physical Society, 2013-12)
    We present methods that can provide an exponential savings in the resources required to perform dynamic parameter estimation using quantum systems. The key idea is to merge classical compressive sensing techniques with ...
  • Sanzeni, Alex; Whittle, Andrew; Germaine, John T.; Colleselli, Francesco (American Society of Civil Engineers (ASCE), 2012-10)
    A laboratory test program was conducted to evaluate the one-dimensional (1D) compression and creep properties of intact sand (and silty-sand) samples from a deep borehole at the Malamocco Inlet to the Venice Lagoon. The ...
  • Tang, Jing; Du, Ning; Doyle, Patrick S. (National Academy of Sciences (U.S.), 2011-09)
    We experimentally study the effects of a uniform electric field on the conformation of single DNA molecules. We demonstrate that a moderate electric field (~200 V/cm) strongly compresses isolated DNA polymer coils into ...
  • Voronin, Sergey; Mikesell, Dylan; Nolet, Guust (Springer Berlin Heidelberg, 2015-05)
    We introduce and compare new compression approaches to obtain regularized solutions of large linear systems which are commonly encountered in large scale inverse problems. We first describe how to approximate matrix vector ...
  • Campagne, Fabien; Dorff, Kevin C.; Chambwe, Nyasha; Robinson, James T.; Mesirov, Jill P. (Public Library of Science, 2013-11)
    Large biological datasets are being produced at a rapid pace and create substantial storage challenges, particularly in the domain of high-throughput sequencing (HTS). Most approaches currently used to store HTS data are ...
  • Juba, Brendan Andrew; Kalai, Adam Tauman; Khanna, Sanjeev; Sudan, Madhu (Institute for Theoretical Computer Science, 2011-01)
    Compression is a fundamental goal of both human language and digital communication, yet natural language is very different from compression schemes employed by modern computers. We partly explain this difference using ...
  • Daniels, Noah M.; Gallant, Andrew; Peng, Jian; Cowen, Lenore J.; Baym, Michael Hartmann; Berger Leighton, Bonnie (Oxford University Press, 2013-06)
    Motivation: The exponential growth of protein sequence databases has increasingly made the fundamental question of searching for homologs a computational bottleneck. The amount of unique data, however, is not growing nearly ...
  • Marwah, Kshitij; Wetzstein, Gordon; Bando, Yosuke; Raskar, Ramesh (Association for Computing Machinery, 2013-07)
    Light field photography has gained a significant research interest in the last two decades; today, commercial light field cameras are widely available. Nevertheless, most existing acquisition approaches either multiplex a ...
  • Hirsch, Matthew Waggener; Wetzstein, Gordon; Raskar, Ramesh (Association for Computing Machinery, 2014-07)
    For about a century, researchers and experimentalists have strived to bring glasses-free 3D experiences to the big screen. Much progress has been made and light field projection systems are now commercially available. ...
  • Heide, Felix; Gregson, James; Wetzstein, Gordon; Raskar, Ramesh; Heidrich, Wolfgang (Optical Society of America, 2014-06)
    Compressive displays are an emerging technology exploring the co-design of new optical device configurations and compressive computation. Previously, research has shown how to improve the dynamic range of displays and ...
  • Medard, Muriel; Feizi-Khankandi, Soheil; Effros, Michelle (Institute of Electrical and Electronics Engineers (IEEE), 2011-02)
    In this paper, we demonstrate some applications of compressive sensing over networks. We make a connection between compressive sensing and traditional information theoretic techniques in source coding and channel coding. ...
  • Grant, Elyot; Indyk, Piotr (Association for Computing Machinery (ACM), 2013-06)
    Compressive sensing is a method for acquiring high dimensional signals (e.g., images) using a small number of linear measurements. Consider an n-pixel image x ∈ R[superscript n], where each pixel p has value x[subscript ...
  • Gupta, Rishi V.; Indyk, Piotr; Price, Eric C.; Rachlin, Yaron (Association for Computing Machinery (ACM), 2011-06)
    We propose a framework for compressive sensing of images with local geometric features. Specifically, let x ∈ R[superscript N] be an N-pixel image, where each pixel p has value x[subscript p]. The image is acquired by ...
  • Demanet, Laurent; Peyre, Gabriel (Springer-Verlag, 2011-02)
    This paper presents a method for computing the solution to the time-dependent wave equation from the knowledge of a largely incomplete set of eigenfunctions of the Helmholtz operator, chosen at random. While a linear ...
