#### 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 ...

#### 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. ...

#### On the eigenfunctions for Hookean and FENE dumbbell models

(AIP Publishing, 2013-09)

We study the linear eigenvalue problem for the distribution function associated with Hookean and FENE dumbbell models. For Hookean dumbbells, the eigenfunctions can be expressed by generalized Laguerre polynomials. The ...

#### Bridging Frameworks for Understanding Numerical Cognition

(Leibniz-Institute for Psychology Information (ZPID), 2018-06-07)

#### 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 ...

#### Stabilizing gene regulatory networks through feedforward loops

(American Institute of Physics, 2013-06)

The global dynamics of gene regulatory networks are known to show robustness to perturbations in the form of intrinsic and extrinsic noise, as well as mutations of individual genes. One molecular mechanism underlying this ...

#### Spontaneous penetration of a non-wetting drop into an exposed pore

(American Institute of Physics, 2013-05)

We consider the penetration process of a liquid drop approaching an exposed pore along the axis of symmetry, which is intended to model the penetration of non-wetting drops into a porous medium. Inertia and gravity are ...

#### A volume-of-fluid formulation for the study of co-flowing fluids governed by the Hele-Shaw equations

(American Institute of Physics, 2013-08)

We present a computational framework to address the flow of two immiscible viscous liquids which co-flow into a shallow rectangular container at one side, and flow out into a holding container at the opposite side. Assumptions ...
