  • Spring, Bryan Q.; Palanisami, Akilan; Zheng, Lei Zak; Blatt, Amy E.; Bryan Sears, R.; Hasan, Tayyaba (SPIE, 2013-09)
    We introduce immunofluorescence and automated image processing protocols for serial tumor sections to objectively and efficiently quantify tumor microvasculature following antivascular therapy. To determine the trade-off ...
  • Zhao, Qin; Bruening, Derek; Amarasinghe, Saman P. (Association for Computing Machinery, 2010)
    Shadow memory is used by dynamic program analysis tools to store metadata for tracking properties of application memory. The efficiency of mapping between application memory and shadow memory has substantial impact on the ...
  • Chen, Zhexu (Michael); Chen, Lei; Cetin, Mujdat; Willsky, Alan S. (Institute of Electrical and Electronics Engineers (IEEE), 2009-08)
    We propose a new approach for multi-sensor multi-target tracking by constructing statistical models on graphs with continuous-valued nodes for target states and discrete-valued nodes for data association hypotheses. These ...
  • Kreidl, Olivier Patrick; Willsky, Alan S. (Institute of Electrical and Electronics Engineers (IEEE), 2010-02)
    A promising feature of emerging wireless sensor networks is the opportunity for each spatially-distributed node to measure its local state and transmit only information relevant to effective global decision-making. An ...
  • Deits, Robin Lloyd Henderson; Tedrake, Russell Louis (Institute of Electrical and Electronics Engineers (IEEE), 2015-05)
    We present a new approach to the design of smooth trajectories for quadrotor unmanned aerial vehicles (UAVs), which are free of collisions with obstacles along their entire length. To avoid the non-convex constraints ...
  • 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 ...
  • Anahtar, Melis N.; Bowman, Brittany A.; Kwon, Douglas (MyJoVE Corporation, 2016-04)
    There is a growing appreciation for the role of microbial communities as critical modulators of human health and disease. High throughput sequencing technologies have allowed for the rapid and efficient characterization ...
  • 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 ...
  • Kaminer, Ido Efraim; Katan, Yaniv Tenenbaum; Buljan, Hrvoje; Shen, Yichen; Ilic, Ognjen; Lopez, Josue Jacob; Wong, Liang Jie; Joannopoulos, John; Soljacic, Marin (Nature Publishing Group, 2016-06)
    Graphene plasmons have been found to be an exciting plasmonic platform, thanks to their high field confinement and low phase velocity, motivating contemporary research to revisit established concepts in light–matter ...
  • Harwood, Stuart Maxwell; Barton, Paul I. (Springer London, 2016-02)
    This work presents a general theory for the construction of a polyhedral outer approximation of the reachable set (“polyhedral bounds”) of a dynamic system subject to time-varying inputs and uncertain initial conditions. ...
  • 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 ...
  • Ma, Yunhan; Li, Jiayu; Wang, Ge; Ke, Qiong; Qiu, Sien; Gao, Liang; Wan, Haifeng; Zhou, Yang; Xiang, Andy Peng; Huang, Qunshan; Feng, Guoping; Zhou, Qi; Yang, Shihua (Springer Nature, 2016-05)
    The efficiency of assisted reproductive technologies (ARTs) in nonhuman primates is low due to no screening criterions for selecting sperm, oocyte, and embryo as well as its surrogate mothers. Here we analyzed 15 pairs of ...
  • 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 ...
  • Wensing, Patrick M.; Palmer, Luther R.; Orin, David E. (Springer Science+Business Media, 2015-01)
    This paper presents new recursive dynamics algorithms that enable operational-space control of floating-base systems to be performed at faster rates. This type of control approach requires the computation of operational-space ...
  • 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 ...
