  • Baran, Thomas A.; Wei, Dennis; Oppenheim, Alan V. (Institute of Electrical and Electronics Engineers (IEEE), 2010-03)
    In designing discrete-time filters, the length of the impulse response is often used as an indication of computational cost. In systems where the complexity is dominated by arithmetic operations, the number of nonzero ...
  • Demaine, Erik D.; Aloupis, Greg; Collette, Sébastien; Damian, Mirela; Langerman, Stefan; O’Rourke, Joseph; Ramaswami, Suneeta; Wuhrer, Stefanie (Elsevier, 2009-08)
    In this paper we propose a novel algorithm that, given a source robot S and a target robot T , reconfigures S into T. Both S and T are robots composed of n atoms arranged in 2 × 2 × 2 meta-modules. The reconfiguration ...
  • Taylor, Joshua A.; Hover, Franz S. (Institute of Electrical and Electronics Engineers (IEEE), 2011-05)
    We apply a linear relaxation procedure for polynomial optimization problems to transmission system planning. The approach recovers and improves upon existing linear models based on the DC approximation. We then consider ...
  • Liang, Xiangdong; Deng, D. S.; Nave, J. C.; Johnson, Steven G. (Cambridge University Press, 2011-08)
    Motivated by complex multi-fluid geometries currently being explored in fibre-device manufacturing, we study capillary instabilities in concentric cylindrical flows of $N$ fluids with arbitrary viscosities, thicknesses, ...
  • Abbe, Emmanuel A.; Zheng, Lizhong (Institute of Electrical and Electronics Engineers / IEEE Information Theory Society, 2010-11)
    Over discrete memoryless channels (DMC), linear decoders (maximizing additive metrics) afford several nice properties. In particular, if suitable encoders are employed, the use of decoding algorithms with manageable ...
  • Levin, Anat; Durand, Fredo (Institute of Electrical and Electronics Engineers (IEEE), 2010-08)
    Acquiring and representing the 4D space of rays in the world (the light field) is important for many computer vision and graphics applications. Yet, light field acquisition is costly due to their high dimensionality. ...
  • Dong, Andy; Sarkar, Somwrita; Honda, Tomonori; Yang, Maria (Springer-Verlag, 2013-11)
    This paper addresses the problem of describing the decision-making process of a committee of engineers based upon their verbalized linguistic appraisals of alternatives. First, we show a way to model an individual’s ...
  • Byrne, Michael Patrick; O'Gorman, Paul Ambrose (American Geophysical Union (AGU), 2013-10)
    Simulations of warming climates with coupled climate models exhibit strong land-ocean contrasts in changes in surface temperature and relative humidity, but little land-ocean contrast in changes in equivalent potential ...
  • Gifford, Scott Michael; Sharma, Shalabh; Moran, Mary Ann (Frontiers Research Foundation, 2014-04)
    For bacterial communities containing hundreds to thousands of distinct populations, connecting functional processes and environmental dynamics at high taxonomic resolution has remained challenging. Here we use the expression ...
  • Kim, Dohoon; Tsai, Li-Huei (New York Academy of Sciences, 2009-08)
    Aberrant cell cycle activity and DNA damage have been observed in neurons in association with various neurodegenerative conditions. While there is strong evidence for a causative role for these events in neurotoxicity, it ...
  • Jin, Bilian; Ernst, Jason; Tiedemann, Rochelle L.; Xu, Hongyan; Sureshchandra, Suhas; Kellis, Manolis; Dalton, Stephen; Liu, Chen; Choi, Jeong-Hyeon; Robertson, Keith D. (Elsevier, 2012-11)
    DNA methylation, mediated by the combined action of three DNA methyltransferases (DNMT1, DNMT3A, and DNMT3B), is essential for mammalian development and is a major contributor to cellular transformation. To elucidate how ...
  • Bomblies, Arne; Laminou, Ibrahim M; Duchemin, Jean-Bernard; Yamana, Teresa K.; Eltahir, Elfatih A. B. (BioMed Central Ltd, 2013-08)
    Background: Individuals continuously exposed to malaria gradually acquire immunity that protects from severe disease and high levels of parasitization. Acquired immunity has been incorporated into numerous models of malaria ...
  • Moxley, Joel F.; Jewett, Michael C.; Antoniewicz, Maciek R.; Villas-Boas, Silas G.; Alper, Hal; Wheeler, Robert T.; Tong, Lily V.; Hinnebusch, Alan G.; Ideker, Trey; Nielsen, Jens; Stephanopoulos, Gregory (National Academy of Sciences, 2009-04)
    Genome sequencing dramatically increased our ability to understand cellular response to perturbation. Integrating system-wide measurements such as gene expression with networks of protein–protein interactions and transcription ...
  • Huang, Shao-shan Carol; Clarke, David C.; Gosline, Sara Jane Calafell; Labadorf, Adam; Chouinard, Candace R.; Gordon, William; Lauffenburger, Douglas A.; Fraenkel, Ernest (Public Library of Science, 2013-02)
    Cellular signal transduction generally involves cascades of post-translational protein modifications that rapidly catalyze changes in protein-DNA interactions and gene expression. High-throughput measurements are improving ...
  • Lambrecht, Bart M.; Myers, Stewart C. (John Wiley & Sons, Inc, 2012-10)
    We develop a dynamic agency model in which payout, investment, and financing decisions are made by managers who attempt to maximize the rents they take from the firm, subject to a capital market constraint. Managers smooth ...
  • Chen, Haogang; Mao, Yandong; Wang, Xi; Zhou, Dong; Zeldovich, Nickolai; Kaashoek, M. Frans (Association for Computing Machinery (ACM), 2011-07)
    Avoiding kernel vulnerabilities is critical to achieving security of many systems, because the kernel is often part of the trusted computing base. This paper evaluates the current state-of-the-art with respect to kernel ...
  • Duplantier, Bertrand; Sheffield, Scott Roger (Springer-Verlag, 2010-12)
    Consider a bounded planar domain D, an instance h of the Gaussian free field on D, with Dirichlet energy ... and a constant 0[less than or equal to]γ<2. The Liouville quantum gravity measure on D is the weak limit as ...
  • Peng, Zhangli; Dao, Ming; Suresh, Subra; Li, Xuejin; Pivkin, Igor V.; Karniadakis, George E. (National Academy of Sciences (U.S.), 2013-08)
    We study the biomechanical interactions between the lipid bilayer and the cytoskeleton in a red blood cell (RBC) by developing a general framework for mesoscopic simulations. We treated the lipid bilayer and the cytoskeleton ...
  • Chaparro, Jose P.; Bershteyn, A.; Riley, E. B.; Yao, R. S.; Zachariah, Roshini Sarah; Irvine, Darrell J. (Institute of Electrical and Electronics Engineers, 2009-05)
    The physicochemical context in which molecules are presented at the surfaces of microbes has tremendous implications for the immune response to vaccination. The spacing and mobility of molecules may control interactions ...
  • Ong, Ta-Chung; Clark, Lindsay; Teijido, Oscar; van der Wel, Patrick C. A.; Garces, Robert; Wagner, Gerhard; Rostovtseva, Tatiana K.; Eddy, Matthew Thomas; Griffin, Robert Guy (American Chemical Society (ACS), 2012-03)
    We employ a combination of [superscript 13]C/[superscript 15]N magic angle spinning (MAS) NMR and [superscript 2]H NMR to study the structural and functional consequences of different membrane environments on VDAC1 and, ...
