  • 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 ...
  • 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 ...
  • 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 ...
  • Movassaghi, Mohammad; Boyer, Nicolas Cedric (Royal Society of Chemistry, The, 2012-03)
    The first total synthesis of (+)-gliocladin B is described. Our concise and enantioselective synthesis takes advantage of a new regioselective Friedel–Crafts-based strategy to provide an efficient multigram-scale access ...
  • Dig, Danny; Marrero, John J.; Ernst, Michael D. (Institute of Electrical and Electronics Engineers, 2009-06)
    Parallelizing existing sequential programs to run efficiently on multicores is hard. The Java 5 package java.util.concurrent (j.u.c.) supports writing concurrent programs. To use this package, programmers still need to ...
  • Harahap, Filino; Lesmana, Herry; Sambegoro, Poetro Lebdo (Springer-Verlag, 2009-11)
    Concurrent calorimetric and interferometric studies have been conducted to investigate the effect that reduction of the base-plate dimensions has on the steady-state performance of the rate of natural convection heat ...
  • Hawkins, Peter; Aiken, Alex; Fisher, Kathleen; Rinard, Martin C.; Sagiv, Mooly (Association for Computing Machinery (ACM), 2012-06)
    We describe an approach for synthesizing data representations for concurrent programs. Our compiler takes as input a program written using concurrent relations and synthesizes a representation of the relations as sets of ...
  • Kaess, Michael; Williams, Stephen; Indelman, Vadim; Roberts, Richard; Leonard, John Joseph; Dellaert, Frank (Institute of Electrical and Electronics Engineers, 2012-07)
    This paper presents a novel algorithm for integrating real-time filtering of navigation data with full map/trajectory smoothing. Unlike conventional mapping strategies, the result of loop closures within the smoother serve ...
