  • Demory, Brice-Olivier (IOP Publishing, 2014-06)
    Exoplanet research focusing on the characterization of super-Earths is currently limited to the handful of targets orbiting bright stars that are amenable to detailed study. This Letter proposes to look at alternative ...
  • Shafia, Ehsan; Esposito, Serena; Manzoli, Maela; Chiesa, Mario; Tiberto, Paola; Barrera, Gabriele; Menard, Gabriel; Allia, Paolo; Garrone, Edoardo; Bonelli, Barbara; Freyria, Francesca Stefania (Springer Netherlands, 2015-08)
    Textural, magnetic and spectroscopic properties are reported of Fe-doped aluminosilicate nanotubes (NTs) of the imogolite type, IMO, with nominal composition (OH)[subscript 3]Al[subscript 2−x]Fe[subscript x]O[subscript ...
  • Chung, Jinwook; Hoke, William E.; Chumbes, Eduardo M.; Palacios, Tomas (Institute of Electrical and Electronics Engineers (IEEE), 2010-03)
    We report on a gate-recessed AlGaN/GaN high-electron mobility transistor (HEMT) on a SiC substrate with a record power-gain cutoff frequency (f[subscript max]). To achieve this high f[subscript max], we combined a low-damage ...
  • Harvey, Nicholas J. A. (Society for Industrial and Applied Mathematics, 2009-07)
    We present new algebraic approaches for two well-known combinatorial problems: nonbipartite matching and matroid intersection. Our work yields new randomized algorithms that exceed or match the efficiency of existing ...
  • Benjamini, Itai; Tessera, Romain; Finucane, Hilary Kiyo (Institute of Mathematical Statistics, 2013-04)
    Initial steps are presented towards understanding which finitely generated groups are almost surely generated as a semigroup by the path of a random walk on the group.
  • Post, Sarah; Vinet, Luc; Genest, Vincent (Springer US, 2016-03)
    The multivariate quantum q-Krawtchouk polynomials are shown to arise as matrix elements of “q-rotations” acting on the state vectors of many q-oscillators. The focus is put on the two-variable case. The algebraic interpretation ...
  • Polyanskiy, Yury; Hosseini Roozbehani, Hajir (Institute of Electrical and Electronics Engineers (IEEE), 2014-06)
    In information theory, structural system constraints are frequently described in the form of a directed acyclic graphical model (DAG). This paper addresses the question of classifying DAGs up to an isomorphism. By considering ...
  • Kim, MinJi; Medard, Muriel (Institute of Electrical and Electronics Engineers (IEEE), 2010-10)
    The deterministic wireless relay network model, introduced by Avestimehr et al., has been proposed for approximating Gaussian relay networks. This model, known as the ADT network model, takes into account the broadcast ...
  • 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 ...
