Finding MEMo: minimum sets of elementary flux modes [PDF]

open access: yesJournal of Mathematical Biology, 2019
Metabolic network reconstructions are widely used in computational systems biology for in silico studies of cellular metabolism. A common approach to analyse these models are elementary flux modes (EFMs), which correspond to minimal functional units in ...

Collective modes in flux line liquids [PDF]

open access: yesSuperconductor Science and Technology, 2000
We study the collective modes of flux line liquids such as occur in the type-II superconductors of recent interest composed of two-dimensional layered structures. Starting from the vortex-vortex interaction and employing the dielectric formalism within the random-phase approximation, we find propagating sound modes in the long-wavelength limit.

Characters, quasinormal modes, and Schwinger pairs in dS2 with flux

open access: yesJournal of High Energy Physics, 2022
An integral representation of the 1-loop partition function for charged scalars and spinors, minimally coupled to a uniform U(1) field on S 2, is given in terms of SO(1, 2) Harish-Chandra group characters and evaluated exactly in terms of Hurwitz ζ ...

Poynting Flux of MHD Modes in Magnetic Solar Vortex Tubes [PDF]

open access: yesThe Astrophysical Journal
Magnetic flux tubes in the presence of background rotational flows, known as solar vortex tubes, are abundant throughout the solar atmosphere and may act as conduits for MHD waves to transport magnetic energy to the upper solar atmosphere.

Estimating biological elementary flux modes that decompose a flux distribution by the minimal branching property [PDF]

open access: yesBioinformatics, 2014
AbstractMotivation: Elementary flux mode (EFM) is a useful tool in constraint-based modeling of metabolic networks. The property that every flux distribution can be decomposed as a weighted sum of EFMs allows certain applications of EFMs to studying flux distributions.

Not just a circle: flux modes in the plant TCA cycle.

open access: yesTrends in Plant Science, 2010
The tricarboxylic acid (TCA) cycle is one of the iconic pathways in metabolism. The cycle is commonly thought of in terms of energy metabolism, being responsible for the oxidation of respiratory substrates to drive ATP synthesis. However, the reactions of carboxylic acid metabolism are embedded in a larger metabolic network and the conventional TCA ...

Elementary flux modes analysis of functional domain networks allows a better metabolic pathway interpretation. [PDF]

open access: yesPLoS One, 2013
Metabolic network analysis is an important step for the functional understanding of biological systems. In these networks, enzymes are made of one or more functional domains often involved in different catalytic activities.
