    • Understanding the complex patterns observed during hepatitis B Virus therapy 

      Rodriguez, Andrea Carracedo; Chung, Matthias; Ciupe, Stanca M. (MDPI, 2017-05-19)
      Data from human clinical trials have shown that the hepatitis B virus (HBV) follows complex profiles, such as bi-phasic, tri-phasic, stepwise decay and rebound. We utilized a deterministic model of HBV kinetics following ...
    • uniqueness of solutions to linearized Boltzmann equation 

      Garbanati, L. F.; Greenberg, W.; Zweifel, P. F. (AIP Publishing, 1978-01)
      Uniqueness theorems are proved for the linearized Boltzmann equation for both the ’’exterior’’ and ’’interior’’ problems under generalized Maxwellboundary conditions. The solution space is a weighted L p space, and agrees ...
    • Using startup of steady shear flow in a sliding plate rheometer to determine material parameters for the purpose of predicting long fiber orientation 

      Ortman, K.; Baird, Donald G.; Wapperom, P.; Whittington, A. (AIP Publishing, 2012-07-01)
      The properties of long glass fiber reinforced parts, such as those manufactured by means of injection molding and compression molding, are highly dependent on the fiber orientation generated during processing. A sliding ...
    • Using transient shear rheology to determine material parameters in fiber suspension theory 

      Eberle, A. P. R.; Baird, Donald G.; Wapperom, P.; Velez-Garcia, G. M. (AIP Publishing, 2009-05-01)
      Fiber suspension theory model parameters for use in the simulation of fiber orientation in complex flows are, in general, either calculated from theory or fit to experimentally determined fiber orientation generated in ...
    • viscosity and density stratification in vertical Poiseuille flow 

      Renardy, Y. (AIP Publishing, 1987-06)
      The linear stability of plane three_layer vertical Poiseuille flow is considered. The layers are composed of two immiscible fluids, one next to the walls and one centrally located. The fluids have different viscosities and ...
    • Vlasov theory of plasma oscillations: linear-approximation 

      Arthur, M. D.; Greenberg, W.; Zweifel, P. F. (AIP Publishing, 1977)
      A functional analytic approach to the linearized collisionless Vlasov equation is presented utilizing a resolvent integration technique on the resolvent of the transport operator evaluated at a particular point. Formulae ...
    • wall energy relaxation in the Cahn-Hilliard model for moving contact lines 

      Yue, P. T.; Feng, J. J. (AIP Publishing, 2011-01)
      The Cahn-Hilliard model uses diffusion between fluid components to regularize the stress singularity at a moving contact line. In addition, it represents the dynamics of the near-wall layer by the relaxation of a wall ...
    • wave operators for the matrix Zakharov-Shabat system 

      Klaus, M.; van der Mee, C. (AIP Publishing, 2010-05)
      In this article, we prove the similarity (and, in the focusing case, the J-unitary equivalence) of the free Hamiltonian and the restriction of the full Hamiltonian to the maximal invariant subspace on which its spectrum ...
    • wave scattering in one dimension with absorption 

      Aktosun, T.; Klaus, M.; van der Mee, C. (AIP Publishing, 1998-04)
      Wave scattering is analyzed in a one-dimensional nonconservative medium governed by the generalized Schrodinger equation d(2) psi/dx(2)+k(2) psi=[ikP(x)+Q(x)]psi, where P(x) and Q(x) are real, integrable potentials with ...
    • why do soliton equations come in hierarchies 

      Yordanov, R. G. (AIP Publishing, 1993-09)
      In this article, an identity satisfied by the so-called recursion operator is derived. The identity generates by itself an infinite sequence of Lax pairs, thus ensuring the complete integrability of the corresponding ...
    • Wolfgang von Ohnesorge 

      McKinley, G. H.; Renardy, M. (American Institute of Physics, 2011-12)
      This manuscript got started when one of us (G.H.M.) presented a lecture at the Institute of Mathematics and its Applications at the University of Minnesota. The presentation included a photograph of Rayleigh and made ...
