      We investigate recovery of the (Schrodinger) potential function from many boundary measurements at a large wavenumber. By considering such a linearized form, we obtain a Holder type stability which is a big improvement ...
    • Lipschitz stability in the lateral Cauchy problem for elasticity system

    • Logistic vector random fields with logistic direct and cross covariances 

      Balakrishnan, N.; Ma, Chunsheng; Wang, Renxiang (Elsevier B.V., 2015-06)
      The logistic vector random field is introduced in this paper as a scale mixture of Gaussian vector random fields, and is thus a particular elliptically contoured (spherically invariant) vector random field. Such a logistic ...

      Meyer, Holger; Muether, Mathew; Solomey, Nickolas (Springer, 2020-10-22)
      The sensitivity of the Deep Underground Neutrino Experiment (DUNE) to neutrino oscillation is determined, based on a full simulation, reconstruction, and event selection of the far detector and a full simulation and ...
    • Machine learning applied to programming quantum computers 

      Steck, James E.; Behrman, Elizabeth C.; Thompson, Nathan L. (American Institute of Aeronautics and Astronautics, 2019-01-06)
      We apply machine learning to “program” quantum computers, both in simulation and in experimental hardware. A major difficulty in quantum computing is developing effective algorithms that can be programmed on a quantum ...
    • Matched-pairs tests of homogeneity with applications to homologous nucleotide sequences 

      Ababneh, Faisal; Jermiin, Lars S.; Ma, Chunsheng; Robinson, John (Oxford University Press, 2006-05-15)
      Motivation: Most phylogenetic methods assume that the sequences of nucleotides or amino acids have evolved under stationary, reversible and homogeneous conditions. When these assumptions are violated by the data, there ...

    • Metrics of positive scalar curvature and generalised Morse functions, part II 

      Walsh, Mark (American Mathematical Society, 2014-01)
      The surgery technique of Gromov and Lawson may be used to construct families of positive scalar curvature metrics which are parameterised by Morse functions. This has played an important role in the study of the space of ...

    • Models for inviscid wakes past a normal plate 

      Elcrat, Alan R.; Zannetti, L. (Cambridge University Press, 2012-10-10)
      Closed and open hollow wakes are considered as analytic models for the two-dimensional inviscid steady flow past a plate normal to the stream. It is shown that only open configurations which satisfy the Kutta condition ...
