  • Lipson, Mark; Loh, Po-Ru; Levin, Alexander; Reich, David; Patterson, Nick; Berger, Bonnie (Oxford University Press, 2013-05)
    The recent explosion in available genetic data has led to significant advances in understanding the demographic histories of and relationships among human populations. It is still a challenge, however, to infer reliable ...
  • Hassidim, Avinatan; Onak, Krzysztof; Edelman, Alan; Nguyen, Huy N. (Springer-Verlag, 2011-06)
    Partitioning oracles were introduced by Hassidim et al. (FOCS 2009) as a generic tool for constant-time algorithms. For any ε > 0, a partitioning oracle provides query access to a fixed partition of the input bounded-degree ...
  • Henderson, Jaclyn L.; Buchwald, Stephen Leffler (Organic Letters, 2010-09)
    The Pd-catalyzed amination of unprotected benzo-fused heterocycles is reported, which allows for greater flexibility and efficiency in the modification of this important class of molecules. The generality of these simple ...
  • Ramadass, Yogesh Kumar; Chandrakasan, Anantha P. (Institute of Electrical and Electronics Engineers, 2010-01)
    Harvesting ambient vibration energy through piezoelectric means is a popular energy harvesting technique which can potentially supply 10-100's of [mu]W of available power. One of the main limitations of existing piezoelectric ...
  • Ramadass, Yogesh Kumar; Chandrakasan, Anantha P. (Institute of Electrical and Electronics Engineers, 2009-05)
    Energy harvesting is an emerging technology with applications to handheld, portable and implantable electronics. Harvesting ambient vibration energy through piezoelectric (PE) means is a popular energy harvesting technique ...
  • He, Ruijie; Brunskill, Emma; Roy, Nicholas (AI Access Foundation, 2011-02)
    Deciding how to act in partially observable environments remains an active area of research. Identifying good sequences of decisions is particularly challenging when good control performance requires planning multiple ...
  • Fors, Brett P.; Buchwald, Stephen Leffler; Davis, Nicole Rose (American Chemical Society (ACS), 2009-04)
    An investigation into Pd-catalyzed C−N cross-coupling reactions of aryl iodides is described. NaI is shown to have a significant inhibitory effect on these processes. By switching to a solvent system in which the iodide ...
  • Quattoni, Ariadna; Carreras Perez, Xavier; Collins, Michael (Association for Computing Machinery, 2009-01)
    In recent years the l[subscript 1],[subscript infinity] norm has been proposed for joint regularization. In essence, this type of regularization aims at extending the l[subscript 1] framework for learning sparse models to ...
  • Delaney, James C.; Gao, Jianmin; Liu, Haibo; Shrivastav, Nidhi; Essigmann, John M.; Kool, Eric T. (Wiley Blackwell, 2009-05)
    Supersize me! Size-expanded DNA bases (xDNA) are able to encode natural DNA sequences in replication. In vitro experiments with a DNA polymerase show nucleotide incorporation opposite the xDNA bases with correct pairing. ...
  • Vempala, Santosh; Belloni, Alexandre; Freund, Robert Michael (Institute for Operations Research and the Management Sciences (INFORMS), 2009-08)
    The classical perceptron algorithm is an elementary row-action/relaxation algorithm for solving a homogeneous linear inequality system Ax > 0. A natural condition measure associated with this algorithm is the Euclidean ...
  • Elfadel, Ibrahim M.; El-Moselhy, Tarek Ali; Dewey, Bill (Institute of Electrical and Electronics Engineers, 2009-08)
    Due to technology scaling, integrated circuit manufacturing techniques are producing structures with large variabilities in their dimensions. To guarantee high yield, the manufactured structures must have the proper ...
  • Arsie, Alessandro; Savla, Ketan; Frazzoli, Emilio (Institute of Electrical and Electronics Engineers / IEEE Control Systems Society, 2009-09)
    In this paper, we consider a class of dynamic vehicle routing problems, in which a number of mobile agents in the plane must visit target points generated over time by a stochastic process. It is desired to design motion ...

  • Fallon, Maurice Francis; Johannsson, Hordur; Leonard, John Joseph (Institute of Electrical and Electronics Engineers (IEEE), 2013-05-14)
    This paper presents Kinect Monte Carlo Localization (KMCL), a new method for localization in three dimensional indoor environments using RGB-D cameras, such as the Microsoft Kinect. The approach makes use of a low fidelity ...
  • Kartner, Franz X.; Nejadmalayeri, Amir H.; Roberts, Tony D.; Wong, Franco N. C. (Institute of Electrical and Electronics Engineers, 2009-08)
    Continuous channel waveguides in periodically poled KTiOPO[subscript 4] with guided orthogonal polarizations are used to demonstrate type-II background-free second harmonic generation at 1505 nm with 1.2 %/(W cm[superscript ...
  • Juba, Brendan Andrew; Sudan, Madhu (Institute for Computer Science, Tsinghua University, 2011-01)
    In previous works, Juba and Sudan [1] and Goldreich, Juba and Sudan [2] considered the idea of “semantic communication”, wherein two players, a user and a server, attempt to communicate with each other without any prior ...
  • Chryssostomidis, Chryssostomos; Karniadakis, George E. (Elsevier, 2009)
    Using simulation results from three different regional ocean models (HOPS, ROMS and FVCOM) we show that only a few spatio-temporal POD (proper orthogonal decomposition) modes are sufficient to describe the most energetic ...

  • Sive, Hazel L.; Rienzo, Gianluca De; Gutzman, Jennifer H. (Mary Ann Liebert, 2012-07)
    Despite the broad repertoire of loss of function (LOF) tools available for use in the zebrafish, there remains a need for a simple and rapid method that can inhibit expression of genes at later stages. RNAi would fulfill ...
  • Peraud, Jean-Philippe Michel; Hadjiconstantinou, Nicolas (American Physical Society (APS), 2011-11)
    We present a Monte Carlo method for obtaining solutions of the Boltzmann equation to describe phonon transport in micro- and nanoscale devices. The proposed method can resolve arbitrarily small signals (e.g., temperature ...
