    • I Know It When I See It: Toward a Definition of Direct Search Methods 

      Trosset, Michael W. (1996-06)
      We discuss some ambiguities associated with the phrase "direct search method" and propose a formal definition.
    • “I Love You But I Disagree”: Politeness and Politics in Computer-Mediated Discourse 

      Mauney, Samantha; Jeon, Lisa; Linguistics Department (2014)
      In this paper we explore the possibility of new politeness paradigms in computer -mediated discourse on Facebook. Specifically, we examine the discoursal expectations, linguistic catalysts for ‘face-threatening acts’, and mitigations of opinions to maintain ‘face’ in discourse about politics. The present study addresses the gap in the literature ...
    • IAH: Reconstituting the coordinates 

      An, Elaine (2006)
      "A demented amoeba [that has] turned itself inside out" (Banham) is one way to describe the living organism we call the contemporary airport. It has a habit of growing haphazardly and unplanned. It combines the infrastructure of politics, technology, economy and ecology into a single urban artifact without an urban framework. Despite their scale, ...
    • ICL-based mid-infrared carbon dioxide sensor system for deep-sea natural gas hydrate exploration 

      Liu, Zhiwei; Zheng, Chuantao; Chen, Chen; Li, Yafei; Xie, Hongtao; (2019)
      For deep-sea natural gas hydrate exploration, highly sensitive detection of the dissolved gas in seawater near the seabed is significant because it requires the sensor system to be small in size, low in power consumption, and high in sensitivity. A mid-infrared sensor system was developed to detect dissolved carbon dioxide (CO2) in sea-water, while ...

      At the Large Hadron Collider, the identification of jets originating from b quarks is important for searches for new physics and for measurements of standard model processes. A variety of algorithms has been developed by CMS to select b-quark jets based on variables such as the impact parameters of charged-particle tracks, the properties of reconstructed ...
    • Identification of hadronic tau lepton decays using a deep neural network 

      The CMS collaboration (2022)
      A new algorithm is presented to discriminate reconstructed hadronic decays of tau leptons (τh) that originate from genuine tau leptons in the CMS detector against τh candidates that originate from quark or gluon jets, electrons, or muons. The algorithm inputs information from all reconstructed particles in the vicinity of a τh candidate and employs ...
    • Identification of heavy, energetic, hadronically decaying particles using machine-learning techniques 

      The CMS collaboration (2020)
      Machine-learning (ML) techniques are explored to identify and classify hadronic decays of highly Lorentz-boosted W/Z/Higgs bosons and top quarks. Techniques without ML have also been evaluated and are included for comparison. The identification performances of a variety of algorithms are characterized in simulated events and directly compared with ...
    • Identification of Instantaneous Frequency and Damping From Transient Decay Data 

      Jin, Mengshi; Chen, Wei; Brake, Matthew R.W.; Song, Hanwen (2020)
      Jointed interfaces, damage, wear, or non-idealized boundary conditions often introduce nonlinear characteristics to assembled structures. Consequently, extensive research has been carried out regarding nonlinear system identification. The development of nonlinear system identification is also enabling the intentional application of nonlinearities ...
    • Identification of Novel Short BaTiO3-Binding/Nucleating Peptides for Phage-Templated in Situ Synthesis of BaTiO3 Polycrystalline Nanowires at Room Temperature 

      Li, Yan; Cao, Binrui; Yang, Mingying; Zhu, Ye; Suh, Junghae; (2016)
      Ferroelectric materials, such as tetragonal barium titanate (BaTiO3), have been widely used in a variety of areas including bioimaging, biosensing, and high power switching devices. However, conventional methods for the synthesis of tetragonal phase BaTiO3 usually require toxic organic reagents and high temperature treatments, and are thus not ...
    • Identification of Regional Variation in the Constitutive Response of Axisymmetric Membranes 

      Boriek, Aladin M.; Cox, Steven J. (2000-09)
      We demonstrate that the equilibrium equations for an axisymmetric, nonlinear, anisotropic membrane under hydrostatic pressure allow explicit representation of the longitudinal and azimuthal stresses in terms of the associated longitudinal and azimuthal strains. We apply this result in a numerical simulation of the canine diaphragm. More precisely, ...
    • An Identification Scheme for the Determination of Systemic Arterial Load Parameters 

      Ling, R.Y.S.; Clark, Jr., J.W.; Srinivasan, R.; Cole, J.S.; Pruett, R.C. (1975-04-20)
      An identification scheme is developed for the determination of several parameters of a modified "Windkessel" model of the systemic arterial system for an individual patient undergoing cardiac catheterization. The scheme utilizes a modification of the well-known Prony method [10,11] as a "starter method" to determine good nominal values for the model ...
    • Identification techniques for highly boosted W bosons that decay into hadrons 

      CMS Collaboration; Adair, A.; Akgun, B.; Ecklund, K.M.; Geurts, F.J.M.; (2014)
      In searches for new physics in the energy regime of the LHC, it is becoming increasingly important to distinguish single-jet objects that originate from the merging of the decay products of W bosons produced with high transverse momenta from jets initiated by single partons. Algorithms are defined to identify such W jets for different signals of ...

      Background: The levels of soluble sugars, such as glucose and sucrose, help regulate many plant metabolic, physiological and developmental processes. Genetic screens are helping identify some of the loci involved in plant sugar response and reveal extensive cross-talk between sugar and phytohormone response pathways. Results: A forward genetic screen ...
    • Identified Hadron Compositions in p+p and Au+Au Collisions at High Transverse Momenta at √sNN=200  GeV 

      STAR Collaboration; Eppley, G.; Geurts, F.; Llope, W.J.; McDonald, D.; (2012)
      We report transverse momentum (pT≤15  GeV/c) spectra of π±, K±, p, p¯, K0S, and ρ0 at midrapidity in p+p and Au+Au collisions at √sNN=200  GeV. Perturbative QCD calculations are consistent with π± spectra in p+p collisions but do not reproduce K and p(p¯) spectra. The observed decreasing antiparticle-to-particle ratios with increasing pT provide ...

      Affinito, Ricardo (2013-05-29)
      Based on the identification of market dynamics, capital allocation in long positions can be dynamically controlled by means of interrupting an otherwise strictly-long investment strategy allowing for an overall improved risk profile and faster response times during periods of persistent negative market returns. Herein, a portfolio selection methodology ...
    • Identifying Anticyclonic Vortex Features Produced by the Rossby Wave Instability in Protoplanetary Disks 

      Huang, Pinghui; Isella, Andrea; Li, Hui; Li, Shengtai; Ji, Jianghui (2018)
      Several nearby protoplanetary disks have been observed to display large-scale crescents in the (sub)millimeter dust continuum emission. One interpretation is that these structures correspond to anticyclonic vortices generated by the Rossby wave instability within the gaseous disk. Such vortices have local gas overdensities and are expected to concentrate ...
