#### A Network Biology Approach to Denitrification in Pseudomonas aeruginosa

(2015-02-23)

Pseudomonas aeruginosa is a metabolically flexible member of the Gammaproteobacteria. Under anaerobic conditions and the presence of nitrate, P. aeruginosa can perform (complete) denitrification, a respiratory process of ...

#### 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. ...

#### Using startup of steady shear flow in a sliding plate rheometer to determine material parameters for the purpose of predicting long fiber orientation

(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 ...

#### Model reduction of descriptor systems by interpolatory projection methods

(Siam Publications, 2013)

In this paper, we investigate an interpolatory projection framework for model reduction of descriptor systems. With a simple numerical example, we first illustrate that directly applying the subspace conditions from 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 ...

#### A state space error estimate for pod-deim nonlinear model reduction

(Siam Publications, 2012)

This paper derives state space error bounds for the solutions of reduced systems constructed using proper orthogonal decomposition (POD) together with the discrete empirical interpolation method (DEIM) recently developed ...

#### 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 ...

#### Inexact solves in interpolatory model reduction

(Elsevier Science Inc, 2012-04-15)

#### Interpolatory weighted-H-2 model reduction

(Pergamon-Elsevier Science Ltd, 2013-05-01)
