  • Stanciu, Stefan G.; Xu, Shuoyu; Peng, Qiwen; Yan, Jie; Stanciu, George A.; Welsch, Roy E.; So, Peter T. C.; Csucs, Gabor; Yu, Hanry (Nature Publishing Group, 2014-04)
    The accurate staging of liver fibrosis is of paramount importance to determine the state of disease progression, therapy responses, and to optimize disease treatment strategies. Non-linear optical microscopy techniques ...
  • Tow, Emily W.; Lienhard, John H. (Elsevier, 2014-03)
    Humidification–dehumidification is a promising technology for decentralized, small-scale desalination, but conventional dehumidifiers are expensive due to the large surface area required. Direct-contact dehumidification ...
  • Wang, Kai; Luo, Meng; Wierzbicki, Tomasz (Springer Netherlands, 2014-03)
    With the emergence of advanced high strength steels (AHSSs) and other light–weight materials, edge fracture has been one of the important issues evading reliable prediction using CAE tools. To study edge fracture behavior ...
  • Bolger, Adrienne M.; Faulkner, Matt; Stein, David B.; White, Lauren L.; Yun, Seung-kook; Rus, Daniela L. (Institute of Electrical and Electronics Engineers (IEEE), 2010-12)
    Our prior work presented a decentralized algorithm for coordinating the construction of truss shaped objects out of multiple components (rods and connectors). In this paper, we consider how to transfer the theory to practice, ...
  • Gilbertson, Eric W.; Leighton, Joshua C.; Cheung, Mei Yi; Hover, Franz S.; Reed, Brooks (Institute of Electrical and Electronics Engineers (IEEE), 2013-05)
    Marine robots are an increasingly attractive means for observing and monitoring in the ocean, but underwater acoustic communication (“acomms”) remains a major challenge, especially for real-time control. Packet loss occurs ...
  • Papadopoulos, Georgios; Kurniawati, Hanna; Shariff, Ahmed Shafeeq Bin Mohd; Wong, Liang Jie; Patrikalakis, Nicholas M. (Wiley Blackwell, 2013-10)
    Over the past 10 years, significant scientific effort has been dedicated to the problem of three-dimensional (3-D) surface reconstruction for structural systems. However, the critical area of marine structures remains ...
  • Futrell, Richard Landy Jones; Gibson, Edward A. (Association for Computational Linguistics, 2015-09)
    We present experiments with generative models for linearization of unordered labeled syntactic dependency trees (Belz et al., 2011; Rajkumar and White, 2014). Our linearization models are derived from generative models for ...
  • Xie, Guodong; Ren, Yongxiong; Huang, Hao; Lavery, Martin P. J.; Ahmed, Nisar; Yan, Yan; Bao, Changjing; Li, Long; Zhao, Zhe; Cao, Yinwen; Willner, Moshe; Padgett, Miles J.; Tur, Moshe; Dolinar, Samuel J.; Boyd, Robert W.; Willner, Alan; Shapiro, Jeffrey H. (Optical Society of America, 2014-03)
    An intensity-only based algorithm is employed to compensate the turbulence effects on 50-Gbaud/s orbital angular momentum QPSK channels. By only measuring the intensity profile, the purity of the OAM beams is improved and ...
  • Siam, Mohamed Salah; Eltahir, Elfatih A. B. (Copernicus GmbH, 2015-03)
    This study analyzes extensive data sets collected during the twentieth century and defines four modes of natural variability in the flow of the Nile River, identifying a new significant potential for improving predictability ...
  • Angrist, Joshua; Pathak, Parag; Walters, Christopher R. (American Economic Association, 2013-10)
    Lottery estimates suggest Massachusetts' urban charter schools boost achievement well beyond that of traditional urban public schools students, while nonurban charters reduce achievement from a higher baseline. The fact ...
  • Ullman, Orly; Stultz, Collin M.; Fisher, Charles K. (American Chemical Society (ACS), 2011-10)
    Given that α-synuclein has been implicated in the pathogenesis of several neurodegenerative disorders, deciphering the structure of this protein is of particular importance. While monomeric α-synuclein is disordered in ...
  • Selin, Noelle Eckley; Song, Shaojie (2013-04)
    Multiple observational analyses have identified a decreasing trend over the past decade in surface concentrations of gaseous elemental mercury (GEM), from sites in both the Northern and Southern hemisphere. We use two ...
  • Yablo, Stephen (Oxford University Press, 2012-10)
    Mark Colyvan (2010) raises two problems for ‘easy road’ nominalism about mathematical objects. The first is that a theory’s mathematical commitments may run too deep to permit the extraction of nominalistic content. Taking ...
  • Wilde, Mark M.; Guha, Saikat; Tan, Si-Hui; Lloyd, Seth (Institute of Electrical and Electronics Engineers (IEEE), 2012-07)
    An important practical open question has been to design explicit, structured optical receivers that achieve the Holevo limit in the contexts of optical communication and “quantum reading.” The Holevo limit is an achievable ...
  • Hutchinson, Ian H.; Patacchini, Leonardo (Academic Press, 2008-12)
    A new explicit time-reversible orbit integrator for the equations of motion in a static homogeneous magnetic field – called Cyclotronic integrator – is presented. Like Spreiter and Walter’s Taylor expansion algorithm, for ...
  • Blondel, Vincent D.; Gurbuzbalaban, Mert; Megretski, Alexandre; Overton, Michael L. (Institute of Electrical and Electronics Engineers (IEEE), 2010-12)
    Given a family of real or complex monic polynomials of fixed degree with one fixed affine constraint on their coefficients, consider the problem of minimizing the root radius (largest modulus of the roots) or abscissa ...

  • Petillo, Stephanie; Schmidt, Henrik (Institute of Electrical and Electronics Engineers (IEEE), 2014-01)
    Advances in the fields of autonomy software and environmental sampling techniques for autonomous underwater vehicles (AUVs) have recently allowed for the merging of oceanographic data collection with the testing of emerging ...
  • Herr, Hugh M.; Hofmann, Andreas; Popovic, Marko (Institute of Electrical and Electronics Engineers, 2009-07)
    Recent humanoid control investigations have emphasized the importance of controlling whole-body angular momentum throughout a movement task. For typical movement tasks, such as normal walking, such controllers minimize ...
  • Grosse, Roger Baker; Salakhutdinov, Ruslan; Freeman, William T.; Tenenbaum, Joshua B. (AUAI Press, 2012-08)
    The recent proliferation of richly structured probabilistic models raises the question of how to automatically determine an appropriate model for a dataset. We investigate this question for a space of matrix decomposition ...
