  • Kartner, Franz X.; Capasso, F.; Gordon, Ariel; Gkortsas, Vasileios-Marios; Wang, C.; Jirauschek, C.; Kuznetsova, L.; Diehl, L.; Belkin, M. A.; Belyanin, A. (Institute of Electrical and Electronics Engineers, 2009-08)
    A theoretical study of active mode-locking in quantum cascade lasers including spatial hole-burning is presented. It is found that spatial hole-burning reduces the pulse duration at the expense of slight pulse instability ...
  • Perera, U. G. E.; Kulik, H. J.; Iancu, V.; Dias da Silva, L. G. G. V.; Ulloa, S. E.; Marzari, Nicola; Hla, S. W. (American Physical Society, 2010-09)
    An extensive redistribution of spin density in TBrPP-Co molecules adsorbed on a Cu(111) surface is investigated by monitoring Kondo resonances at different locations on single molecules. Remarkably, the width of the Kondo ...
  • Evans, Daniel A.; Ogle, P. M.; Marshall, Herman Lee; Nowak, Michael A.; Bianchi, S.; Guainazzi, M.; Dewey, Dan; Schulz, Norbert S.; Noble, Mike S.; Houck, John C.; Canizares, Claude R. (American Institute of Physics, 2010-07)
    We present initial results from a new 440-ks Chandra HETG GTO observation of the canonical Seyfert 2 galaxy NGC 1068. The proximity of NGC 1068, together with Chandra's superb spatial and spectral resolution, allow an ...
  • Kang, Peter Kyungchul; Juanes, Ruben; Dentz, Marco; Borgne, Tanguy Le (American Physical Society (APS), 2011-10)
    Flow through lattice networks with quenched disorder exhibits a strong correlation in the velocity field, even if the link transmissivities are uncorrelated. This feature, which is a consequence of the divergence-free ...
  • Chan, Juliana Maria; Zhang, Liangfang; Tong, Rong; Ghosh, Debadyuti; Gao, Weiwei; Liao, Grace V.; Yuet, Kai P.; Gray, David; Rhee, June-Wha; Cheng, Jianjun; Golomb, Gershon; Libby, Peter; Langer, Robert; Farokhzad, Omid C. (National Academy of Sciences, 2010-02)
    There are a number of challenges associated with designing nanoparticles for medical applications. We define two challenges here: (i) conventional targeting against up-regulated cell surface antigens is limited by heterogeneity ...
  • Copeland, Andrew D.; Mangoubi, Rami S.; Desai, Mukund N.; Mitter, Sanjoy K.; Malek, Adel M. (Institute of Electrical and Electronics Engineers (IEEE), 2010-06)
    This paper provides a framework for generating high resolution time sequences of 3D images that show the dynamics of cerebral blood flow. These sequences have the potential to allow image feedback during medical procedures ...
  • Dura, Burak; Kovacs, Gregory T. A.; Giovangrandi, Laurent (Public Library of Science, 2012-04)
    Background: Methods for the electrical inhibition of cardiac excitation have long been sought to control excitability and conduction, but to date remain largely impractical. High-amplitude alternating current (AC) ...
  • Cedolin, Leonardo; Delgutte, Bertrand (Society for Neuroscience, 2010-09)
    The pitch of harmonic complex tones plays an important role in speech and music perception and the analysis of auditory scenes, yet traditional rate–place and temporal models for pitch processing provide only an incomplete ...
  • Chua, Song-Liang; Caccamise, Christine A.; Phillips, Dane J.; Joannopoulos, John D.; Soljacic, Marin; Everitt, Henry O.; Bravo-Abad, Jorge (Optical Society of America, 2011-04)
    We investigate laser emission from optically-pumped rotationally excited molecular gases confined in a metallic cavity. To this end, we have developed a theoretical framework able to accurately describe, both in the spatial ...
  • Nijholt, Anton; Pantic, Maja; Pentland, Alex Paul (Institute of Electrical and Electronics Engineers, 2009-02)
    The seven articles in this special issue focus on human computing. Most focus on two challenging issues in human computing, namely, machine analysis of human behavior in group interactions and context-sensitive modeling.
  • Auroux, Denis (International Press of Boston, 2009-08)
    In this survey paper, we briefly review various aspects of the SYZ approach to mirror symmetry for non-Calabi-Yau varieties, focusing in particular on Lagrangian fibrations and wall-crossing phenomena in Floer homology. ...
  • Engels, Daniel W.; Cole, Peter; McFarlane, Duncan; Mickle, Marlin H.; Sarma, Sanjay Emani (Institute of Electrical and Electronics Engineers, 2009-01)
    The eight articles in this special section describe state-of-the-art technologies and tools and one application of RFID.
  • Cerutti, Sergio; Magenes, Giovanni; Bonato, Paolo (Institute of Electrical and Electronics Engineers, 2010-05)
    The 12 papers in this special section are original and relevant contributions in the area of smart wearable devices (SWDs) applied to the health and civil protection domain.
  • Kar, Kenneth; Cheng, Wai K. (SAE International, 2009-11)
    Engine-out HC emissions from a PFI spark ignition engine were measured using a gas chromatograph and a flame ionization detector (FID). Two port fuel injectors were used respectively for ethanol and gasoline so that the ...
  • Rasmussen, Steven; Kingston, Derek; Karaman, Sertac; Frazzoli, Emilio (2009-07)
    Formal languages have recently come under attention as a powerful tool to describe in a precise and rigorous way mission specifications (i.e., mission objectives and constraints) for robotic systems, and to design planning ...
  • Badizadegan, Kamran; Dasari, Ramachandra Rao; Yaqoob, Zahid; Choi, Wonshik; Feld, Michael S.; Park, YongKeun (Optical Society of America, 2009-07)
    The use of coherent light in conventional holographic phase microscopy (HPM) poses three major drawbacks: poor spatial resolution, weak depth sectioning, and fixed pattern noise due to unwanted diffraction. Here, we ...
  • Sanner, Christian Burkhard; Su, Edward Joseph; Keshet, Aviv; Huang, Wujie; Gillen, Jonathon Isaiah; Gommers, Ralf; Ketterle, Wolfgang (American Physical Society, 2011-01)
    Spin fluctuations and density fluctuations are studied for a two-component gas of strongly interacting fermions along the Bose-Einstein condensate-BCS crossover. This is done by in situ imaging of dispersive speckle patterns. ...
  • Kennedy, Brendan F.; Curatolo, Andrea; Sampson, David D.; Hillman, Timothy Robert; Saunders, Christobel M. (Society of Photo-optical Instrumentation Engineers, 2011-02)
    We present a technique to reduce speckle in optical coherence tomography images of soft tissues. An average is formed over a set of B-scans that have been decorrelated by viscoelastic creep strain. The necessary correction ...
