Do elementary flux modes combine linearly at the “atomic” level? Integrating tracer-based metabolomics data and elementary flux modes

BioSystems, 2011
The elementary flux modes (EFMs) approach is an efficient computational tool to predict novel metabolic pathways. Elucidating the physiological relevance of EFMs in a particular cellular state is still an open challenge. Different methods have been presented to carry out this task.

Elementary flux modes, flux balance analysis, and their application to plant metabolism.

Methods in molecular biology, 2014
In recent years the number of sequenced and annotated plant genomes has increased significantly, and novel approaches are required to retrieve valuable information from these data sets. The field of systems biology has accelerated the simulation and prediction of phenotypes derived from specific genotypic modifications under defined growth conditions ...

Inference of dynamic macroscopic models of cell metabolism based on elementary flux modes analysis

Biochemical engineering journal, 2019
This study aims at providing a methodology based on both data- and knowledge-driven approaches to build dynamic macroscopic models of cell cultures. This methodology proceeds in three steps.

A method for the determination of flux in elementary modes, and its application toLactobacillus rhamnosus [PDF]

Biotechnology and Bioengineering, 2004
In this article we address the question of how, given information about the reaction fluxes of a system, flux values can be assigned to the elementary modes of that system.

Massless Mode of Abrikosov Flux Lattice

Journal of the Physical Society of Japan, 1990
The massless mode of harmonic fluctuations of the Abrikosov flux lattice is studied in detail within the GL theory. Without relying on the usual approximation to neglect all but the lowest Landau level we prove exactly that no terms quadratic in k 0 appear in the spectrum of this mode where k 0 is the wave vector of fluctuations perpendicular to the ...

A new non‐linear sliding‐mode torque and flux control method for an induction machine incorporating a sliding‐mode flux observer

International Journal of Robust and Nonlinear Control, 2004
AbstractIn this paper a novel sliding‐mode control algorithm, based on the differential geometry state‐co‐ordinates transformation method, is proposed to control motor torque directly. Non‐linear feedback linearization theory is employed to decouple the control of rotor flux magnitude and motor torque.

Measuring Intracellular Calcium Fluxes in High Throughput Mode

Combinatorial Chemistry & High Throughput Screening, 2003
The measurement of intracellular calcium fluxes in real time is widely applied within the pharmaceutical industry to measure the activation of G-protein coupled receptors (GPCRhyp;s), either for pharmacological characterisation or to screen for new surrogate ligands.
