  • Jaworski, Frank B.; Bawendi, Moungi G.; Geyer, Scott M.; Scherer, Jennifer Marie (Optical Society of America, 2013-07)
    The high infrared quantum yield, continuous absorption spectrum, and band edge tunability of colloidal quantum dots (QD) has opened up new opportunities to use luminescent down shifting for multispectral imaging in the ...
  • Gershman, Samuel J.; Vul, Edward; Tenenbaum, Joshua B. (MIT Press, 2012-01)
    Ambiguous images present a challenge to the visual system: How can uncertainty about the causes of visual inputs be represented when there are multiple equally plausible causes? A Bayesian ideal observer should represent ...
  • Gupta, Shubham; Bertsimas, Dimitris J. (AGIFORS - International Federation of Operational Research Societies, 2011-10)
    In this paper, we study the first application of robust and adaptive optimization in the Air Traffic Flow Management (ATFM) problem. The existing models for network-wide ATFM assume deterministic capacity estimates across ...
  • Wong, Cliff; Stylianopoulos, Triantafyllos; Cui, Jian; Martin, John; Chauhan, Vikash P.; Jiang, Wen; Popovic, Zoran; Jain, Rakesh K.; Bawendi, Moungi G.; Fukumura, Dai (National Academy of Sciences (U.S.), 2011-02)
    Current Food and Drug Administration-approved cancer nanotherapeutics, which passively accumulate around leaky regions of the tumor vasculature because of an enhanced permeation and retention (EPR) effect, have provided ...
  • Manzoni, Cristian; Cerullo, Giulio; Moses, Jeffrey; Huang, Shu-Wei; Kärtner, Franz X. (Institute of Electrical and Electronics Engineers, 2009-08)
    We present a procedure for simultaneous optimization of efficiency-bandwidth product and superfluorescence noise suppression in ultrabroadband high-energy optical parametric chirped pulse amplification. Gain dependence of ...
  • Grogan, Paul Thomas; Shirasaka, Seiko; Golkar, Alessandro; de Weck, Olivier L. (Institute of Electrical and Electronics Engineers (IEEE), 2014-03)
    Federated satellite systems (FSS) are a new class of space-based systems which emphasize a distributed architecture. New information exchanging functions among FSS members enable data transportation, storage, and processing ...
  • Glass, James R.; Saenko, Ekaterina; Livescu, Karen; Darrell, Trevor J. (Institute of Electrical and Electronics Engineers, 2009-09)
    We study the problem of automatic visual speech recognition (VSR) using dynamic Bayesian network (DBN)-based models consisting of multiple sequences of hidden states, each corresponding to an articulatory feature (AF) such ...
  • Drucker, Andrew Donald (Institute of Electrical and Electronics Engineers, 2009-09)
    In Direct Sum problems |8|, one tries to show that for a given computational model, the complexity of computing a collection F = {f[subscript 1](x[subscript 1]),[subscript hellip] f[subscript 1](x[subscript 1])} of finite ...
  • Gupta, Rajiv; Chen, Yi; Chang, Jean H.; Greenlee, Alison S.; Cheung, Kenneth Chun-Wai; Slocum, Alexander H. (Institute of Electrical and Electronics Engineers (IEEE), 2010-05)
    In poorly constrained extra-vascular environments such as hollow viscera, current catheter navigation techniques are restricted to simple paths and therefore limit a doctor's ability to position the catheter. This paper ...
  • Kopeikin, Andrew; Ponda, Sameera S.; Johnson, Luke B.; How, Jonathan P. (Institute of Electrical and Electronics Engineers (IEEE), 2012-12)
    A multi-UAV system relies on communications to operate. Failure to communicate remotely sensed mission data to the base may render the system ineffective, and the inability to exchange command and control messages can lead ...
  • Massachusetts Institute of Technology. Department of Mathematics; Poonen, Bjorn; Poonen, Bjorn (Institute of Mathematics, Polish Academy of Sciences, 2010-12)
    For each number field k, the Bombieri-Lang conjecture for k-rational points on surfaces of general type implies the existence of a polynomial f(x, y) [element of] k[x, y] inducing an injection k x k-->k.
  • McBee, Megan E.; Zheng, Yu; Parry, Nicola Maria Anne; Nagler, Cathryn R.; Tannenbaum, Steven Robert; Schauer, David B. (Public Library of Science, 2010-10)
    Background: Diagnosis of chronic intestinal inflammation, which characterizes inflammatory bowel disease (IBD), along with prediction of disease state is hindered by the availability of predictive serum biomarker. Serum ...
  • Ooi, Boon Teik; Zheng, H.; Kurniawati, Hanna; Cho, W.; Dao, M. H.; Wei, Jun; Zemskyy, P.; Tkalich, P.; Rizzoli, Paola M.; Patrikalakis, Nicholas M. (International Society of Offshore and Polar Engineers, 2009-06)
    Oceanographic features such as jets and vortices are often found downstream of obstacles and landforms such as islands or peninsulas. Such features have high spatial and temporal variability and are, hence, interesting but ...
  • Wilczek, Frank (IOP Publishing, 2013-09)
    Valid ideas that physical reality is vastly larger than human perception of it, and that the perceived part may not be representative of the whole, exist on many levels and have a long history. After a brief general inventory ...
  • Song, Yale; Davis, Randall; Morency, Louis-Philippe (Institute of Electrical and Electronics Engineers (IEEE), 2012-06)
    Many human action recognition tasks involve data that can be factorized into multiple views such as body postures and hand shapes. These views often interact with each other over time, providing important cues to understanding ...
  • Strnad, Lukas; Peelen, Marius V.; Bedny, Marina; Caramazza, Alfonso (Public Library of Science, 2013-04)
    Cross-modal plasticity refers to the recruitment of cortical regions involved in the processing of one modality (e.g. vision) for processing other modalities (e.g. audition). The principles determining how and where ...
  • Zorzos, Anthony Nicholas; Boyden, Edward Stuart; Fonstad, Clifton G., Jr. (Optical Society of America, 2010-12)
    Optical fibers are commonly inserted into living tissues such as the brain in order to deliver light to deep targets for neuroscientific and neuroengineering applications such as optogenetics, in which light is used to ...
  • Chakrabarty, Deepto (IOP Publishing, 2012-05)
    We present multi-wavelength observations of the radio magnetar PSR J1622-4950 and its environment. Observations of PSR J1622-4950 with Chandra (in 2007 and 2009) and XMM (in 2011) show that the X-ray flux of PSR J1622-4950 ...
  • Canizares, Claude R.; Hillwig, Todd; Mioduszewski, Amy; Rupen, Michael; Schulz, Norbert S.; Heinz, Sebastian; Marshall, Herman Lee; Nowak, Michael A. (IOP Publishing, 2013-09)
    We present observations of the SS 433 jets using the Chandra High Energy Transmission Grating Spectrometer with contemporaneous optical and Very Long Baseline Array observations. The X-ray and optical emission line regions ...
  • Marcipar, Lital; Ofer, Oren; Keren, Amit; Nytko, Emily A.; Nocera, Daniel G.; Lee, Young S.; Helton, Joel S.; Bains, Chris (American Physical Society, 2009-10)
    Using muon-spin resonance, we examine the organometallic hybrid compound Cu(1,3-benzenedicarboxylate) [Cu(1,3-bdc)], which has structurally perfect spin-1/2 copper kagome planes separated by pure organic linkers. This ...
