  • Grassl, Markus; Shor, Peter W.; Smith, Graeme; Smolin, John; Zeng, Bei (American Physical Society, 2009-05)
    We discuss the concept of generalized concatenated quantum codes. This generalized concatenation method provides a systematical way for constructing good quantum codes, both stabilizer codes and nonadditive codes. Using ...
  • Grassl, Markus; Zeng, Bei; Shor, Peter W. (Institute of Electrical and Electronics Engineers, 2009-08)
    We show how good quantum error-correcting codes can be constructed using generalized concatenation. The inner codes are quantum codes, the outer codes can be linear or nonlinear classical codes. Many new good codes are ...
  • Demaine, Erik D.; Price, Gregory N. (Springer-Verlag, 2009-09)
    A convex surface that is flat everywhere but on finitely many smooth curves (or seams) and points is a seam form. We show that the only creases through the flat components of a seam form are either between vertices or ...
  • Iadecola, Thomas; Chamon, Claudio; Jackiw, Roman; Pi, So-Young (American Physical Society, 2013-09)
    Driven condensed matter systems consistently pose substantial challenges to theoretical understanding. Progress in the study of such systems has been achieved using the Floquet formalism, but certain aspects of this approach ...
  • Yu, Xiangyao; Ren, Ling; Devadas, Srinivas; Fletcher, Christopher Wardlaw; van Dijk, Marten (Association for Computing Machinery (ACM), 2013-11)
    This paper investigates secure ways to interact with tamper-resistant hardware leaking a strictly bounded amount of information. Architectural support for the interaction mechanisms is studied and performance implications ...
  • Domínguez-García, A. D.; Schindall, Joel E.; Kassakian, John G. (Institute of Electrical and Electronics Engineers, 2009-05)
    This paper proposes a fault coverage model for linear time-invariant (LTI) systems subject to uncertain input. A state-space representation, defined by the state-transition matrix, and the input matrix, is used to represent ...
  • Mistry, Karan Hemant; Lienhard, John H. (MDPI AG, 2013-05)
    Increasing global demand for fresh water is driving the development and implementation of a wide variety of seawater desalination technologies driven by different combinations of heat, work, and chemical energy. This paper ...
  • Gattami, Ather Said (Institute of Electrical and Electronics Engineers, 2010-01)
    We consider the problem of stochastic finite- and infinite-horizon linear quadratic control under power constraints. The calculations of the optimal control law can be done off-line as in the classical linear quadratic ...
  • Mason, J. K.; Schuh, Christopher A. (Elsevier B.V., 2009-07)
    A general formulation for the disorientation angle distribution function is derived. The derivation employs the hyperspherical harmonic expansion for orientation distributions, and an explicit solution is presented for ...
  • Hohm, Olaf; Hull, Chris; Zwiebach, Barton (Springer Berlin / Heidelberg, 2010-08)
    The generalized metric is a T-duality covariant symmetric matrix constructed from the metric and two-form gauge field and arises in generalized geometry. We view it here as a metric on the doubled spacetime and use it ...
  • Giovannetti, V; Holevo, A S; Maccone, L; Lloyd, Seth (IOP Publishing, 2010-10)
    A formulation of the generalized minimal output entropy conjecture for Gaussian channels is presented. It asserts that, for states with fixed input entropy, the minimal value of the output entropy of the channel (i.e. the ...
  • Ricci, Nicola; Rhodes, Donna H.; Ross, Adam Michael (Elsevier, 2013-02)
    Due to the complex and highly dynamic contexts in which systems operate nowadays, it has become crucial that, early in the architecting phase, System Architects take into account options to be utilized throughout the ...
  • Goyal, Vivek K.; Deshpande, Ajay A.; Sarma, Sanjay Emani (Institute of Electrical and Electronics Engineers (IEEE), 2010-02)
    We address the optimal sensor arrangement problem, which is the determination of a geometric configuration of sensors such that the mean-squared error (MSE) in the estimation of an unknown trigonometric polynomial is ...
  • Hoffmann, Henry; Maggio, Martina; Santambrogio, Marco D.; Leva, Alberto; Agarwal, Anant (Institute of Electrical and Electronics Engineers (IEEE), 2013-09)
    A number of techniques have been proposed to provide runtime performance guarantees while minimizing power consumption. One drawback of existing approaches is that they work only on a fixed set of components (or actuators) ...
  • Chen, Hui; Joslin, Scott Stephen Walter (Oxford University Press, 2012-07)
    Nonlinearity is an important consideration in many problems of finance and economics, such as pricing securities and solving equilibrium models. This article provides analytical treatment of a general class of nonlinear ...
  • Zhou, Jiawei; Chen, Gang; Liao, Bolin (American Physical Society, 2014-07)
    We generalize the two-temperature model [Sanders and Walton, Phys. Rev. B 15, 1489 (1977)] for coupled phonon-magnon diffusion to include the effect of the concurrent magnetization flow, with a particular emphasis on the ...
  • Margolin, Yelena; Dedon, Peter C. (Springer Science+Business Media, 2010)
    Oxidative damage to DNA has long been associated with aging and disease, with guanine serving as the primary target for oxidation owing to its low ionization potential. Emerging evidence points to a critical role for ...
  • Buchwald, Stephen Leffler; Oberli, Matthias (American Chemical Society (ACS), 2012-08)
    Conditions for the Suzuki–Miyaura coupling of lithium triisopropyl borates are reported, as well as a procedure for a one-pot lithiation, borylation, and subsequent Suzuki–Miyaura coupling of various heterocycles with aryl ...
  • Sobolevsky, Stanislav; Campari, Riccardo; Belyi, Alexander; Ratti, Carlo (American Physical Society, 2014-07)
    Recent years have witnessed the development of a large body of algorithms for community detection in complex networks. Most of them are based upon the optimization of objective functions, among which modularity is the most ...
  • Bosanac, Natasha; Do, Sydney; Wen, Hui Ying; Wicht, Anthony Charles (SPIE, 2010-07)
    The General Purpose Astronomy - Small Satellite (GPA-SS) project studied the feasibility of developing a useful space telescope with a cost to launch below $100 million. An optical telescope assembly (OTA) designed for ...
