#### A Network of SCOP Hidden Markov Models and Its Analysis

(2011-05-23)

Background
The Structural Classification of Proteins (SCOP) database uses a large number of hidden Markov models (HMMs) to represent families and superfamilies composed of proteins that presumably share the same evolutionary ...

#### ADAM: Analysis of Discrete Models of Biological Systems Using Computer Algebra

(2011-07-20)

Background
Many biological systems are modeled qualitatively with discrete models, such as probabilistic Boolean networks, logical models, Petri nets, and agent-based models, to gain a better understanding of them. The ...

#### A regularized Gauss-Newton trust region approach to imaging in diffuse optical tomography

(Siam Publications, 2011)

We present a new algorithm for the solution of nonlinear least squares problems arising from parameterized imaging problems with diffuse optical tomographic data [D. Boas et al., IEEE Signal Process. Mag., 18 (2001), pp. ...

#### A general convergence analysis of some Newton-type methods for nonlinear inverse problems

(Siam Publications, 2011)

We consider the methods x(n+1)(delta) - x(n)(delta) - g(alpha n) (F'(x(n)(delta))* F'(x(n)(delta)))F'(x(n)(delta))*(F(x(n)(delta)) - y(delta)) for solving nonlinear ill-posed inverse problems F(x) = y using the only available ...

#### Glass transition seen through asymptotic expansions

(Siam Publications, 2011)

Soft glassy materials exhibit the so-called glassy transition, which means that the behavior of the model at a low shear rate changes when a certain parameter (which we call the glass parameter) crosses a critical value. ...

#### Numerical investigation of elongated drops in a microfluidic T-junction

(American Institute of Physics, 2011-02)

We present a combined numerical and asymptotic approach for modeling droplets in microchannels. The magnitude of viscous forces relative to the surface tension force is characterized by a capillary number, Ca, which is ...

#### Wolfgang von Ohnesorge

(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 ...

#### wall energy relaxation in the Cahn-Hilliard model for moving contact lines

(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 ...

#### Small-energy analysis for the self-adjoint matrix Schrodinger operator on the half line

(AIP Publishing, 2011-10)

The matrix Schrodinger equation with a self-adjoint matrix potential is considered on the half line with the most general self-adjoint boundary condition at the origin. When the matrix potential is integrable and has a ...

#### Interpolatory projection methods for parameterized model reduction

(Siam Publications, 2011)

We provide a unifying projection-based framework for structure-preserving interpolatory model reduction of parameterized linear dynamical systems, i.e., systems having a structured dependence on parameters that we wish to ...
