    • Enrichment and Fundamental Optical Processes of Armchair Carbon Nanotubes 

      Haroz, Erik (2013-09-16)
      The armchair variety of single-wall carbon nanotubes (SWCNTs) is the only nanotube species that behaves as a metal with no electronic band gap and massless carriers, making them ideally suited to probe fundamental questions ...
    • Environmental Factors Associated With Natural Methane Occurrence in the Appalachian Basin 

      Molofsky, Lisa J.; Connor, John A.; McHugh, Thomas E.; Richardson, Stephen D.; Woroszylo, Casper; Alvarez, Pedro J. (2016)
      The recent boom in shale gas development in the Marcellus Shale has increased interest in the methods to distinguish between naturally occurring methane in groundwater and stray methane associated with drilling and production ...
    • Equilibria and stability boundaries of shallow arches under static loading in a thermal environment 

      Moghaddasie, Behrang; Stanciulescu, Ilinca (2013)
      The structural behaviour of shallow arches is complex and can be influenced by many parameters. In this paper, the response of a half-sine shallow arch under static loading in a thermal environment is investigated. The ...
    • Equilibrium at the edge and atomistic mechanisms of graphene growth 

      Artyukhov, Vasilii I.; Liu, Yuanyue; Yakobson, Boris I. (2012)
      The morphology of graphene is crucial for its applications, yet an adequate theory of its growth is lacking: It is either simplified to a phenomenological-continuum level or is overly detailed in atomistic simulations, ...
    • Equipment-Free Incubation of Recombinase Polymerase Amplification Reactions Using Body Heat 

      Crannell, Zachary Austin; Rohrman, Brittany; Richards-Kortum, Rebecca (2014)
      The development of isothermal amplification platforms for nucleic acid detection has the potential to increase access to molecular diagnostics in low resource settings; however, simple, low-cost methods for heating samples ...
    • Equivalence of Generalized Joint Signal Representations of Arbitrary Variables 

      Sayeed, Akbar M.; Jones, Douglas L. (1996-12-20)
      Joint signal representations (JSRs) of arbitrary variables generalize time-frequency representations (TFRs) to a much broader class of nonstationary signal characteristics. Two main distributional approaches to JSRs of ...
    • The Equivalent Circuit Concept: The Current-Source Equivalent 

      Johnson, Don (2003-05-20)

    • Error control for support vector machines 

      Davenport, Mark A. (2007)
