  • Hunter, Seth Edward; Maes, Patricia; Tang, Anthony; Inkpen, Kori M.; Hessey, Susan M. (Association for Computing Machinery, 2014-05)
    We present the design, and evaluation of WaaZam, a video mediated communication system designed to support creative play in customized environments. Users can interact together in virtual environments composed of digital ...
  • Shaver, David C.; Keast, Craig L.; Wheeler, Bruce D.; Hu, WeiLin; Bolkhovsky, Vladimir; Berger, Robert; Suntharalingam, Vyshnavi; Soares, Antonio M.; Donnelly, Joseph P.; Mahoney, Leonard J.; Oakley, Douglas C.; Chapman, David C.; Knecht, Jeffrey M.; Yost, Donna-Ruth W.; Chen, Chang-Lee (Institute of Electrical and Electronics Engineers, 2009-10)
    In this work, we modified our wafer-scale 3D integration technique, originally developed for Si, to hybridize InP-based image sensor arrays with Si readout circuits. InGaAs image arrays based on the InGaAs layer grown on ...
  • Keast, Craig L.; Chen, Chang-Lee; Chen, Chenson K.; Yost, Donna-Ruth W.; Knecht, Jeffrey M.; Wyatt, Peter W.; Burns, James A.; Warner, Keith; Gouker, Pascale M.; Healey, Paul D.; Wheeler, Bruce D. (Institute of Electrical and Electronics Engineers, 2009-02)
    RF amplifiers are demonstrated using a three- dimensional (3D) wafer-scale integration technology based on silicon-on-insulator (SOI) CMOS process. This new 3D implementation reduces the amplifier size and shortens ...
  • Ansolabehere, Stephen; Stewart III, Charles H (Mary Ann Lieber, 2015-03)
    We review evidence that long lines waiting to vote in the 2012 presidential election were costly and disproportionately appeared in certain regions of the country, in cities, and among minority voters. We argue that the ...
  • Guo, Philip J.; Miller, Robert C.; Cai, Carrie Jun; Glass, James R. (Association for Computing Machinery (ACM), 2014-04)
    Second-language learners are often unable to find time for language practice due to constraints in their daily lives. In this paper, we examine how brief moments of waiting during a person's existing social conversations ...
  • Cai, Carrie Jun; Guo, Philip J; Glass, James R; Miller, Robert C (Association for Computing Machinery, 2015-04)
    Competing priorities in daily life make it difficult for those with a casual interest in learning to set aside time for regular practice. In this paper, we explore wait-learning: leveraging brief moments of waiting during ...
  • Cai, Carrie Jun; Miller, Robert C; Ren, Anji (Association for Computing Machinery (ACM), 2017-03)
    The busyness of daily life makes it difficult to find time for informal learning. Yet, learning requires significant time and effort, with repeated exposures to educational content on a recurring basis. Despite the struggle ...
  • Modarres-Sadeghi, Yahya; Karniadakis, George E.; Bourguet, Remi; Triantafyllou, Michael S. (American Physical Society (APS), 2011-09)
    We identify a dominant mechanism in the interaction between a slender flexible structure undergoing free vibrations in sheared cross-flow and the vortices forming in its wake: energy is transferred from the fluid to the ...
  • Pekour, Mikhail S.; Cziczo, Daniel James (Taylor & Francis, 2011-03)
    Counterflow virtual impaction is used to inertially separate cloud elements from inactivated aerosol. Previous airborne, ground-based, and laboratory studies using this technique exhibit artifacts that are not fully explained ...
  • Hong, Juhee; Teaney, Derek; Chesler, Paul Michael (American Physical Society, 2012-06)
    We compute the nonequilibrium stress tensor induced by a heavy quark moving through weakly coupled QCD plasma at the speed of light and compare the result to N=4 super-Yang-Mills theory at strong coupling. The QCD Boltzmann ...
  • Chen, Zhengbing; Ortiz, Alejandra Campbell; Zong, Lijun; Nepf, Heidi (American Geophysical Union (Wiley platform), 2012-09)
    This experimental study describes the mean and turbulent flow structure in the wake of a circular array of cylinders, which is a model for a patch of emergent vegetation. The patch diameter, D, and patch density, a (frontal ...
  • Tse, Joyce C.; Kalluri, Raghu (BioMed Central Ltd., 2011-06)
    As appreciation grows for the contribution of the tumor microenvironment to the progression of cancer, new evidence accumulates to support that the participation of stromal cells can extend beyond the local environment. ...
  • Ahn, Jooeun; Hogan, Neville (Public Library of Science, 2012-03)
    The control architecture underlying human reaching has been established, at least in broad outline. However, despite extensive research, the control architecture underlying human locomotion remains unclear. Some studies ...
  • Bush, John W. M.; Hu, David L. (American Institute of Physics, 2010-06)
    The ingenious methods employed by insects and spiders to move across a water surface rely on microphysics that is of little use to larger water walkers but of considerable interest to the microfluidics community.
  • Jiang, Yang; Mehndiratta, Shomik; Zegras, P. Christopher (Elsevier, 2011-11)
    This paper examines BRT station walk access patterns in rapidly urbanizing China and the relationship between bus rapid transit (BRT) station context and corridor type and the distance people will walk to access the system ...
  • Chen, Percival Yang-Ting; Drennan, Catherine L.; Wittenborn, Elizabeth Charlot (eLife Sciences Publications, Ltd., 2016-02)
    The metallocofactor involved in fixing nitrogen is not a rigid scaffold, as was previously thought.
  • Scott, Benjamin B.; Gardner, Timothy; Ji, Ni; Fee, Michale S.; Lois, Carlos (Society for Neuroscience, 2012-01)
    Most non-mammalian vertebrate species add new neurons to existing brain circuits throughout life, a process thought to be essential for tissue maintenance, repair, and learning. How these new neurons migrate through the ...
  • Sanjana, Neville E.; Scott, Benjamin Barnett (Society for Neuroscience, 2009-06)
    For proper formation of the cerebral cortex, immature neurons must travel from their birthplace within the walls of the lateral ventricle to their final destinations throughout the brain. This process requires active ...
  • Malakis, A.; Hadjiagapiou, I. A.; Fytas, N. G.; Berker, A. Nihat (Elsevier, 2010-02)
    We study, via a two-stage Wang–Landau (WL) strategy, the random-bond version of the square lattice ferromagnetic Blume–Capel (BC) model, in both the first- and second-order phase transition regimes of the pure model. The ...
  • Angrist, Joshua; Rokkanen, Miikka Aatto Tapio (Informa UK Limited, 2016-01)
    In regression discontinuity (RD) studies exploiting an award or admissions cutoff, causal effects are nonparametrically identified for those near the cutoff. The effect of treatment on inframarginal applicants is also of ...
