  • Chiu, Kevin Geeyoung; Raskar, Ramesh (Institute of Electrical and Electronics Engineers, 2009-08)
    We demonstrate a concept of computer vision as a secure, live service on the Internet. We show a platform to distribute a real time vision algorithm using simple widely available Web technologies, such as Adobe Flash. We ...
  • Holroyd, Michael; Baran, Ilya; Lawrence, Jason; Matusik, Wojciech (Association for Computing Machinery (ACM), 2011-12)
    We present a method for automatically converting a digital 3D model into a multilayer model: a parallel stack of high-resolution 2D images embedded within a semi-transparent medium. Multilayer models can be produced quickly ...
  • Kim, Anthony; Medard, Muriel (Institute of Electrical and Electronics Engineers (IEEE), 2011-10)
    We define a notion of network capacity region of networks that generalizes the notion of network capacity defined by Cannons et al. and prove its notable properties such as closedness, boundedness and convexity when the ...
  • Wilson, Matthew A.; Brown, Emery N.; Sarma, Sridevi V.; Nguyen, David P.; Czanner, Gabriela; Wirth, Sylvia; Suzuki, Wendy (MIT Press, 2011-09)
    Characterizing neural spiking activity as a function of intrinsic and extrinsic factors is important in neuroscience. Point process models are valuable for capturing such information; however, the process of fully applying ...
  • Aloupis, Greg; Bose, Prosenjit; Demaine, Erik D.; Langerman, Stefan; Meijer, Henk; Overmars, Mark; Toussaint, Godfried T. (World Scientific, 2011)
    Given a planar polygon (or chain) with a list of edges {e[subscript 1], e[subscript 2], e[subscript 3], …, e[subscript n-1], e[subscript n]}, we examine the effect of several operations that permute this edge list, resulting ...
  • Gummadi, Ramakrishna; Jung, Kyomin; Shah, Devavrat; Sreenivas, Ramavarapu (Institute of Electrical and Electronics Engineers, 2009-04)
    We consider a wireless network of n nodes that communicate over a common wireless medium under some interference constraints. Our work is motivated by the need for an efficient and distributed algorithm to determine the ...
  • Crandall, Jacob W.; Della Penna, Mauro; de Jong, Paul M. A.; Cummings, M. L. (Institute of Electrical and Electronics Engineers (IEEE), 2011-05)
    In time-critical systems in which a human operator supervises multiple semiautomated tasks, failure of the operator to focus attention on high-priority tasks in a timely manner can lower the effectiveness of the system and ...
  • Adams, Allan; Lapan, Joshua M. (Springer Berlin / Heidelberg, 2011-03)
    We compute the massless spectra of a set of flux vacua of the heterotic string. The vacua we study include well-known non-Kähler T [superscript 2]-fibrations over K3 with SU(3) structure and intrinsic torsion. Following ...
  • Li, Ju; Kushima, Akihiro; Yip, Sidney (Public Library of Science, 2011-03)
    The microscopic origin of glass transition, when liquid viscosity changes continuously by more than ten orders of magnitude, is challenging to explain from first principles. Here we describe the detailed derivation and ...
  • Lee, Jeong Hoon; Han, Jongyoon (Springer-Verlag, 2010-03)
    Here, we report a new method of concentration-enhanced binding kinetics for a rapid immunoassay screening test on a gold surface in a poly(dimethylsiloxane) (PDMS) microfluidic chip format. The use of alkylthiolate ...
  • Nguyen, Ha Q.; Varshney, Lav Raj; Goyal, Vivek K. (Institute of Electrical and Electronics Engineers, 2010-11)
    Permutation codes are a class of structured vector quantizers with a computationally-simple encoding procedure based on sorting the scalar components. Using a codebook comprising several permutation codes as subcodes ...
  • Montfort, Nick
    In 1952 computer scientist Christopher Strachey wrote a parodical love letter generator. This system, the prototype of all computational conceptual writing – the almost completely secret prototype – was up and running ...
  • Dori, Dov; Somekh, Judith; Choder, Mordechai (Public Library of Science, 2012-12)
    We propose a Conceptual Model-based Systems Biology framework for qualitative modeling, executing, and eliciting knowledge gaps in molecular biology systems. The framework is an adaptation of Object-Process Methodology ...
  • Somekh, Judith; Haimovich, Gal; Guterman, Adi; Dori, Dov; Choder, Mordechai (Public Library of Science, 2014-09)
    Biologists are required to integrate large amounts of data to construct a working model of the system under investigation. This model is often informal and stored mentally or textually, making it prone to contain undetected ...
  • Potter, Mary C. (Frontiers Research Foundation, 2012-04)
    Conceptual short term memory (CSTM) is a theoretical construct that provides one answer to the question of how perceptual and conceptual processes are related. CSTM is a mental buffer and processor in which current perceptual ...
  • Medley, Jonathan William; Movassaghi, Mohammad (Wiley Blackwell, 2012-05)
    Building cycles: A strategy for the concise, stereoselective synthesis of aspidosperma alkaloids and related structures via a common putative diiminium ion intermediate is reported. The approach enables the dimerization ...
  • Tsvelikhovsky, Dmitry; Buchwald, Stephen Leffler (American Chemical Society (ACS), 2011-08)
    A general and highly efficient protocol for the synthesis of dibenzodiazepines and their structural analogues is reported. In the presence of catalytic quantities of palladium, readily accessible precursors are cross-coupled ...
  • Han, Sunkyu; Movassaghi, Mohammad (American Chemical Society (ACS), 2011-06)
    The concise and enantioselective total syntheses of (−)-trigonoliimines A, B, and C are described. Our unified strategy to all three natural products is based on asymmetric oxidation and reorganization of a single ...
  • Kim, Justin; Movassaghi, Mohammad (American Chemical Society (ACS), 2011-08)
    Concise and enantioselective total syntheses of (+)-naseseazines A and B are described. Our regioselective and directed dimerization of diketopiperazines provides their critical C3–C[2 over sp] linkages, an assembly with ...
  • Coste, Alexis; Kim, Justin; Adams, Timothy C.; Movassaghi, Mohammad (Royal Society of Chemistry, The, 2013-05)
    The concise and efficient total synthesis of (+)-bionectins A and C is described. Our approach to these natural products features a new and scalable method for erythro-β-hydroxytryptophan amino acid synthesis, an intramolecular ...
