  • Sheng, Xing; Liu, Jifeng; Kozinsky, Inna; Michel, Jurgen; Kimerling, Lionel C.; Agarwal, Anuradha Murthy (Institute of Electrical and Electronics Engineers (IEEE), 2010-06)
    Thin film silicon solar cells are believed to be promising candidates for continuing cost reduction in photovoltaic panels because silicon usage could be greatly reduced. Since silicon is an indirect bandgap semiconductor, ...
  • Bravo-Abad, Jorge; Rodriguez, Alejandro W.; Joannopoulos, John D.; Rakich, P. T.; Johnson, Steven G.; Soljacic, Marin (American Institute of Physics, 2010-03)
    In this letter, we show theoretically how the light-confining properties of triply-resonant photonic resonators can be tailored to enable dramatic enhancements of the conversion efficiency of terahertz (THz) generation via ...
  • Hu, Xiaolong; Holzwarth, Charles W.; Masciarelli, Daniele; Dauler, Eric A.; Berggren, Karl K. (Institute of Electrical and Electronics Engineers, 2009-07)
    We designed superconducting nanowire single-photon detectors (SNSPDs) integrated with silver optical antennae for free-space coupling and a dielectric waveguide for fiber coupling. According to our finite-element simulation, ...
  • Indyk, Piotr; Ngo, Hung Q.; Rudra, Atri (Society for Industrial and Applied Mathematics / Association for Computing Machinery, 2010-01)
    We consider the following "efficiently decodable" non-adaptive group testing problem. There is an unknown string x 2 f0; 1gn [x is an element of set {0,1} superscript n] with at most d ones in it. We are allowed to ...
  • Kuindersma, Scott; Permenter, Frank Noble; Tedrake, Russell Louis (Institute of Electrical and Electronics Engineers (IEEE), 2014-05)
    We describe a whole-body dynamic walking controller implemented as a convex quadratic program. The controller solves an optimal control problem using an approximate value function derived from a simple walking model while ...
  • Shabani, A.; Kosut, R. L.; Mohseni, Masoud; Rabitz, H.; Broome, M. A.; Almeida, M. P.; White, A. G. (American Physical Society, 2011-03)
    The resources required to characterize the dynamics of engineered quantum systems—such as quantum computers and quantum sensors—grow exponentially with system size. Here we adapt techniques from compressive sensing to ...
  • 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 ...
  • 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 ...
