The Functional Bethe Ansatz (FBA) proposed by Sklyanin is a method which gives separation variables for systems for which an R-matrix is known. Previously the FBA was only known for SL(2) and SL(3) (and associated) R-matrices. In this paper I advance Sklyanin's program by giving the FBA for certain systems with SL(N) R-matrices. This is achieved by constructing rational functions A(u) and B(u) ...

The MPEG-4 Face and Body Animation (FBA) specifications aims at standardizing an interchange format for specifying virtual face and body modeling and related animation parameters. The scene graph concept, the FBA nodes, semantics and representation of the animation parameters as well as compression and streaming capabilities are successively addressed. The compatibility between virtual characte...

MetaNetX is a repository of genome-scale metabolic networks (GSMNs) and biochemical pathways from a number of major resources imported into a common namespace of chemical compounds, reactions, cellular compartments--namely MNXref--and proteins. The MetaNetX.org website (http://www.metanetx.org/) provides access to these integrated data as well as a variety of tools that allow users to import th...

Flux-balance modeling of plant metabolic networks provides an important complement to (13)C-based metabolic flux analysis. Flux-balance modeling is a constraints-based approach in which steady-state fluxes in a metabolic network are predicted by using optimization algorithms within an experimentally bounded solution space. In the last 2 years several flux-balance models of plant metabolism have...

Flux balance analysis is the only modelling approach that is capable of producing genome-wide predictions of gene essentiality that may aid to unveil metabolic liabilities in cancer. Nevertheless, a systemic validation of gene essentiality predictions by flux balance analysis is currently missing. Here, we critically evaluated the accuracy of flux balance analysis in two cancer types, clear cel...

Modeling of plant metabolism offers new approaches to improve the understanding of complex biological processes. In this paper we present a framework for the constraintbased stoichiometric analysis of crop plant metabolic models, which combines tools for (1) model reconstruction, (2) model analysis (i.e. flux balance analysis), and (3) model visualization. The approach is illustrated by describ...
