      The variety of isotopes in cosmic rays allows us to study different aspects of the processes that cosmic rays undergo between the time they are produced and the time of their arrival in the heliosphere. In this paper, we ...
    • Isotopic evidence for the source of lead in the North Pacific abyssal water 

      Wu, Jingfeng; Rember, Robert; Jin, Meibin; Boyle, Edward A.; Flegal, A. Russell (Elsevier, 2010-08)
      The absence of accurate measurements of lead (Pb) isotopic composition in the pristine North Pacific abyssal water has made it difficult to assess the relative importance of what are believed to be the two major Pb sources: ...
    • Isotropic actomyosin dynamics promote organization of the apical cell cortex in epithelial cells 

      Bathe, Mark; Diesinger, Philipp M.; Klingner, Christoph; Cherian, Anoop V.; Fels, Johannes; e.a. (Rockefeller University Press, The, 2014-10)
      Although cortical actin plays an important role in cellular mechanics and morphogenesis, there is surprisingly little information on cortex organization at the apical surface of cells. In this paper, we characterize ...
    • Isotropic and energy-selective electron cloaks on graphene 

      Liao, Bolin; Zebarjadi, Mona; Esfarjani, Keivan; Chen, Gang (American Physical Society, 2013-10)
      We propose and investigate a design for “electron cloaks” comprised of two electrodes, one top gate and one back gate, on either side of a graphene sheet arranged in a concentric disk configuration. Dirac electrons with ...
    • Isotropic to anisotropic transition in a fractional quantum Hall state 

      Mulligan, Michael; Nayak, Chetan; Kachru, Shamit (American Physical Society, 2010-08)
      We study an Abelian gauge theory in 2+1 dimensions which has surprising theoretical and phenomenological features. The theory has a vanishing coefficient for the square of the electric field ei2, characteristic of a quantum ...

      Data-constrained dynamical ocean modeling for the purpose of detailed forecasting and prediction continues to evolve and improve in quality. Modeling methods and computational capabilities have each improved. The result ...
    • Issues Faced in a Remote Instrumentation Laboratory 

      Malani, Shreya; Prasanna, G.N. Srinivasa; del Alamo, Jesus A.; Hardison, James; Moudgalya, Kannan; e.a. (Institute of Electrical and Electronics Engineers (IEEE), 2012-07)
      An Online Lab is a multi-university shared laboratory environment, where students can exercise their knowledge as they would do in a physical lab. The idea is to have maximum resource utilization and collaboration between ...
    • Issues in Peer-to-Peer Networking: a Coding Optimization Approach 

      Chang, Christopher S.; Ho, Tracey; Effros, Michelle; Medard, Muriel; Leong, Ben (Institute of Electrical and Electronics Engineers, 2010-06)
      In this paper we consider a linear optimization approach for studying download finish times in peer-to-peer networks that allow but do not require coding. We demonstrate that using the network coding framework simplifies ...
    • Isthmus Stem Cells Are the Origins of Metaplasia in the Gastric Corpus 

      Hayakawa, Yoku; Wang, Timothy C.; Fox, James G (Elsevier BV, 2017-03)
      The acquisition of genetic/epigenetic mutations in long-lived gastrointestinal stem cells leads to the development of cancer, as well as precancerous lesions such as metaplasia and dysplasia. In the proximal stomach corpus, ...
