    • Steady axisymmetric vortex flows with swirl and shear 

      Elcrat, Alan R.; Fornberg, Bengt; Miller, Kenneth G. (Cambridge University Press, 2008-10-01)
      A general procedure is presented for computing axisymmetric swirling vortices which are steady with respect to an inviscid flow that is either uniform at infinity or includes shear. We consider cases both with and without ...

    • Stellar modeling with low-temperature on-the-fly opacity 

      Buchele, Lynn (Wichita State University, 2021-05)
      Accurate stellar modeling requires using our understanding of phenomena far smaller than humans can observe to study some of the largest objects in the universe. One quantity that bridges this gap is the mean opacity, ...

      Ma, Chunsheng (Taylor & Francis Group, 2016)
      A stochastic representation is derived for a vector random field that is stationary, isotropic, and mean square continuous on a sphere or unit circle. The established stochastic representation is an infinite series involving ...
    • Stress testing the vector-boson-fusion approximation in multijet final states 

      Campanario, Francisco; Figy, Terrance M.; Plaetzer, Simon; Rauch, Michael; Schichtel, Peter; Sjodahl, Malin (American Physical Society, 2018-08-22)
      We consider electroweak Higgs plus three jets production at NLO QCD beyond strict VBF acceptance cuts. We investigate, for the first time, how accurate the VBF approximation is in these regions and within perturbative ...
    • Strict Whitney arcs and t-quasi self-similar arcs 

      Wei, Xin (Wichita State University, 2018-05)
      A connected compact subset E of RN is said to be a strict Whitney set if there exists a real-valued C1 function f on RN with ∇f |E ≡ 0 such that f is constant on no non-empty relatively open subsets of E. We prove that ...
