  • Allegra, Michele; Hemmerling, Börge; Wan, Xiaoting; Cappellaro, Paola; Aiello, Clarice D. (Springer US, 2015-07)
    We present an algebraic framework to study the time-optimal synthesis of arbitrary unitaries in SU(2), when the control set is restricted to rotations around two non-parallel axes in the Bloch sphere. Our method bypasses ...
  • Medard, Muriel; Kim, MinJi; Koetter, Ralf; Barros, Joao (Institute of Electrical and Electronics Engineers, 2009-08)
    In this paper, we propose a scheme, called the algebraic watchdog for wireless network coding, in which nodes can detect malicious behaviors probabilistically, police their downstream neighbors locally using overheard ...
  • Kim, MinJi; Medard, Muriel; Barros, Joao (Institute of Electrical and Electronics Engineers (IEEE), 2011-11)
    We propose a secure scheme for wireless network coding, called the algebraic watchdog. By enabling nodes to detect malicious behaviors probabilistically and use overheard messages to police their downstream neighbors ...
  • Wilczek, Frank; Lee, Jae Hoon (American Physical Society, 2013-11)
    Motivated by the problem of identifying Majorana mode operators at junctions, we analyze a basic algebraic structure leading to a doubled spectrum. For general (nonlinear) interactions the emergent mode creation operator ...
  • Koo, Benjamin H. Y.; Simmons, Willard L.; Crawley, Edward F. (Institute of Electrical and Electronics Engineers, 2009-04)
    This paper represents system models as algebraic entities and formulates model transformation activities as algebraic operations. We call this modeling framework ldquoalgebra of systemsrdquo (AoS). To show that AoS can ...

  • Alegado, Rosanna A.; Grabenstatter, Jonathan Dean; Zuzow, Richard; Morris, Andrea; Huang, Sherri Y.; Summons, Roger Everett; King, Nicole (Society for General Microbiology, 2012-02)
    A Gram-negative, non-motile, non-spore-forming bacterial strain, PR1[superscript T], was isolated from a mud core sample containing colonial choanoflagellates near Hog Island, Virginia, USA. Strain PR1[superscript T] grew ...
  • Orlikowski, Wanda J.; Scott, Susan V. (University of Minnesota, 2015)
    This special issue acknowledges important innovations in the world of service and within this domain we are particularly interested in exploring the rise and influence of web-based crowd-sourcing and algorithmic rating and ...
  • Manchester, Ian R. (Institute of Electrical and Electronics Engineers, 2010-01)
    We propose an algorithm for design of optimal inputs for system identification when amplitude constraints on the input and output are imposed. In contrast to input design with signal power constraints, this problem is ...
  • Karafillis, P.; Fouli, Kerim; ParandehGheibi, Ali; Medard, Muriel (Institute of Electrical and Electronics Engineers (IEEE), 2013-03)
    Sliding-window Network Coding (NC) is a variation of Network Coding that is an addition to TCP/IP and improves the throughput of TCP on wireless networks. In this article, two implementations of a new algorithm are proposed ...
  • Kharbouch, Alaa; Shoeb, Ali; Cash, Sydney S.; Guttag, John V. (Elsevier, 2011-11)
    This article addresses the problem of real-time seizure detection from intracranial EEG (IEEG). One difficulty in creating an approach that can be used for many patients is the heterogeneity of seizure IEEG patterns across ...
  • McLean, Noah Morgan; Bowring, J. F.; Bowring, Samuel A. (American Geophysical Union (AGU), 2011-06)
    High-precision U-Pb geochronology by isotope dilution-thermal ionization mass spectrometry is integral to a variety of Earth science disciplines, but its ultimate resolving power is quantified by the uncertainties of ...
  • Cai, Yang; Daskalakis, Konstantinos; Weinberg, Seth Matthew (Association for Computing Machinery (ACM), 2012-05)
    We show that every feasible, Bayesian, multi-item multi-bidder mechanism for independent, additive bidders can be implemented as a mechanism that: (a) allocates every item independently of the other items; (b) for the ...
  • Zhou, Hui; Vonk, Brenda; Roubos, Johannes A.; Voigt, Christopher A.; Bovenberg, Roel A. L. (Oxford University Press, 2015-10)
    Optimizing bio-production involves strain and process improvements performed as discrete steps. However, environment impacts genotype and a strain that is optimal under one set of conditions may not be under different ...
  • Kumar, Abhinav; Cohn, Henry (United States National Academy of Sciences, 2009-04)
    We study inverse statistical mechanics: how can one design a potential function so as to produce a specified ground state? In this article, we show that unexpectedly simple potential functions suffice for certain symmetrical ...
  • Cardinal, Jean; Demaine, Erik D.; Demaine, Martin L.; Imahori, Shinji; Langerman, Stefan; Uehara, Ryuhei (Springer, 2009)
    How do we most quickly fold a paper strip (modeled as a line) to obtain a desired mountain-valley pattern of equidistant creases (viewed as a binary string)? Define the folding complexity of a mountain-valley string as the ...
  • Goemans, Michel X.; Iwata, Satoru; Zenklusen, Rico (Institute of Electrical and Electronics Engineers, 2010-01)
    We consider the wireless relay network model as introduced by Avestimehr, Diggavi and Tse for approximating Gaussian relay channels and show that it is a special case of a more abstract flow model that we introduce in this ...
  • Fedorenko, Evelina; Webster, Jason; Kanwisher, Nancy; Julian, Joshua B. (Elsevier, 2012-03)
    In a widely used functional magnetic resonance imaging (fMRI) data analysis method, functional regions of interest (fROIs) are handpicked in each participant using macroanatomic landmarks as guides, and the response of ...
  • Abel, Zachary Ryan; Demaine, Erik D.; Demaine, Martin L.; Eisenstat, Sarah Charmian; Lubiw, Anna; Schulz, Andre; Souvaine, Diane L.; Viglietta, Giovanni; Winslow, Andrew (Schloss Dagstuhl Publishing, 2013-02)
    We prove that every simple polygon can be made as a (2D) pop-up card/book that opens to any desired angle between 0 and 360°. More precisely, given a simple polygon attached to the two walls of the open pop-up, our ...
  • Kinsy, Michel A.; Devadas, Srinivas (Institute of Electrical and Electronics Engineers (IEEE), 2014-09)
    In this paper we present an Integer Linear Programming (ILP) formulation and two non-iterative heuristics for scheduling a task-based application onto a heterogeneous many-core architecture. Our ILP formulation is able to ...
