  • Bernstein, Michael S.; Brandt, Joel; Miller, Robert C.; Karger, David R. (Association for Computing Machinery (ACM), 2011-10)
    Interactive systems must respond to user input within seconds. Therefore, to create realtime crowd-powered interfaces, we need to dramatically lower crowd latency. In this paper, we introduce the use of synchronous crowds ...
  • Azar, Pablo Daniel; Chen, Jing; Micali, Silvio (Association for Computing Machinery (ACM), 2012)
    We investigate the problem of optimal mechanism design, where an auctioneer wants to sell a set of goods to buyers, in order to maximize revenue. In a Bayesian setting the buyers' valuations for the goods are drawn from a ...
  • Marcus, Adam; Wu, Eugene; Karger, David R.; Madden, Samuel R.; Miller, Robert C. (CIDR, 2011-01)
    Amazon's Mechanical Turk (\MTurk") service allows users to post short tasks (\HITs") that other users can receive a small amount of money for completing. Common tasks on the system include labelling a collection of ...
  • el Kaliouby, Rana; McDuff, Daniel Jonathan; Picard, Rosalind W. (Association for Computing Machinery (ACM), 2011-11)
    In the past, collecting data to train facial expression and affect recognition systems has been time consuming and often led to data that do not include spontaneous expressions. We present the first crowdsourced data ...
  • Bernstein, Michael S.; Hartmann, Bjorn; Chi, Ed H.; Kittur, Aniket; Chilton, Lydia B.; Miller, Robert C. (Association for Computing Machinery (ACM), 2011)
    Crowdsourcing and human computation are transforming human-computer interaction, and CHI has led the way. The seminal publication in human computation was initially published in CHI in 2004 [1], and the first paper ...
  • Kamel Boulos, Maged N.; Resch, Bernd; Crowley, David N.; Breslin, John G.; Sohn, Gunho; Burtner, Russ; Pike, William A.; Jezierski, Eduardo; Chuang, Kuo-Yu S. (BioMed Central Ltd, 2011-12)
    'Wikification of GIS by the masses' is a phrase-term first coined by Kamel Boulos in 2005, two years earlier than Goodchild's term 'Volunteered Geographic Information'. Six years later (2005-2011), OpenStreetMap and Google ...
  • Nguyen, Phu Tran; Weir, Sarah; Guo, Philip J.; Miller, Robert C.; Gajos, Krzysztof Z.; Kim, Ju Ho (Association for Computing Machinery (ACM), 2014-04)
    Millions of learners today use how-to videos to master new skills in a variety of domains. But browsing such videos is often tedious and inefficient because video player interfaces are not optimized for the unique step-by-step ...
  • Overeem, A.; Leijnse, H.; Steeneveld, G. J.; Uijlenhoet, R.; Horn, Berthold Klaus Paul; Robinson, J. C. R. (American Geophysical Union (AGU), 2013-08)
    Accurate air temperature observations in urban areas are important for meteorology and energy demand planning. They are indispensable to study the urban heat island effect and the adverse effects of high temperatures on ...
  • Itzkowitz Shifrinson, Joshua; Priebe, Miranda L. (MIT Press, 2011-07)
    The United States and its Persian Gulf allies have been increasingly concerned with the growing size and complexity of Iran's ballistic missile programs. At a time when the United States and its allies remain locked in a ...
  • James, Peter Benjamin; Zuber, Maria; Phillips, Roger J. (American Geophysical Union, 2013-04)
    The topography of a terrestrial planet can be supported by several mechanisms: (1) crustal thickness variations, (2) density variations in the crust and mantle, (3) dynamic support, and (4) lithospheric stresses. Each of ...
  • Barnes, Alexander; Mak-Jurkauskas, Melody L.; Matsuki, Yoh; Bajaj, Vikram S.; van der Wel, Patrick C.A.; Sirigiri, Jagadishwar R.; Temkin, Richard J.; Lugtenburg, Johan; Herzfeld, Judith; DeRocher, Ronald C.; Bryant, Jeffrey A.; Griffin, Robert Guy (Elsevier, 2009-03)
    We describe a cryogenic sample exchange system that dramatically improves the efficiency of magic angle spinning (MAS) dynamic nuclear polarization (DNP) experiments by reducing the time required to change samples and by ...
  • Popa, Raluca Ada; Redfield, Catherine M.; Zeldovich, Nickolai; Balakrishnan, Hari (Association for Computing Machinery (ACM), 2011-10)
    Online applications are vulnerable to theft of sensitive information because adversaries can exploit software bugs to gain access to private data, and because curious or malicious administrators may capture and leak data. ...
  • Rohner, N.; Jarosz, Daniel F.; Kowalko, J. E.; Yoshizawa, M.; Jeffery, W. R.; Borowsky, R. L.; Tabin, C. J.; Lindquist, Susan (American Association for the Advancement of Science (AAAS), 2013-12)
    In the process of morphological evolution, the extent to which cryptic, preexisting variation provides a substrate for natural selection has been controversial. We provide evidence that heat shock protein 90 (HSP90) ...
  • Beineke, Jennifer; Brubaker, Benjamin Brock; Frechette, Sharon (Birkhauser Boston, 2012-07)
    This paper presents a definition for a family of Weyl group multiple Dirichlet series (henceforth \MDS") of Cartan type C using a combinatorial model for crystal bases due to Berenstein-Zelevinsky [2] and Littelmann [12]. ...
  • Gast, Alice Petry; Horton, Margaret R.; Manley, Suliana; Arevalo, Silvana R.; Lobkovsky, Alexander E. (American Chemical Society (ACS), 2007-01)
    Cellular membranes can take on a variety of shapes to assist biological processes including endocytosis. Membrane-associated protein domains provide a possible mechanism for determining membrane curvature. We study the ...
  • Hou, Chong; Jia, Xiaoting; Wei, Lei; Tan, Swee-Ching; Zhao, Xin; Joannopoulos, John D.; Fink, Yoel (Nature Publishing Group, 2015-02)
    Traditional fibre-optic drawing involves a thermally mediated geometric scaling where both the fibre materials and their relative positions are identical to those found in the fibre preform. To date, all thermally drawn ...
  • Jang, S. A.; Lee, H. J.; Oh, Y. J.; Thompson, Carl V.; Ross, Caroline A. (American Institute of Physics (AIP), 2015-12)
    We analyzed the effect of crystallographic anisotropy on the morphological evolution of a 12-nm-thick goldfilm during solid-state dewetting at high temperatures using automated indexing tool in a transmission electron ...
  • Partridge, James R.; Schwartz, Thomas (Elsevier, 2009-06)
    The nuclear pore complex (NPC) resides in circular openings within the nuclear envelope and serves as the sole conduit to facilitate nucleocytoplasmic transport in eukaryotes. The asymmetric distribution of the small G ...
  • Kung, Yan; Doukov, Tzanko I.; Seravalli, Javier; Ragsdale, Stephen W.; Drennan, Catherine L. (American Chemical Society, 2009-07)
    Nickel-containing carbon monoxide dehydrogenases (CODHs) reversibly catalyze the oxidation of carbon monoxide to carbon dioxide and are of vital importance in the global carbon cycle. The unusual catalytic CODH C-cluster ...
  • Rajni Swamy, V.; Gunasekaran, P.; Krishnakumar, R. V.; Srinivasan, N.; Mueller, Peter (International Union of Crystallography (IUCr), 2014-08)
    The title compound, C[subscript 26]H[subscript 18]F[subscript 3]N[subscript 3]O[subscript 2]S, a 2-meth­oxy-substituted derivative, is closely related to its 4-methyl- and 4-chloro-substituted analogues and yet displays ...
