Eigenvalues of Killing Tensors and Separable Webs on Riemannian and Pseudo-Riemannian Manifolds [PDF]

open access: yes, 2006
Given a $n$-dimensional Riemannian manifold of arbitrary signature, we illustrate an algebraic method for constructing the coordinate webs separating the geodesic Hamilton-Jacobi equation by means of the eigenvalues of $m \leq n$ Killing two-tensors ...

Thermodynamics of non-elementary chemical reaction networks

open access: yesNew Journal of Physics, 2020
We develop a thermodynamic framework for closed and open chemical networks applicable to non-elementary reactions that do not need to obey mass action kinetics.

Generating Functions of Stochastic L-Systems and Application to Models of Plant Development [PDF]

open access: yes, 2008
International audienceIf the interest of stochastic L-systems for plant growth simulation and visualization is broadly acknowledged, their full mathematical potential has not been taken advantage of.

Graphical Modeling of Higher Plants Using P Systems [PDF]

open access: yes, 2006
L systems have been widely used to model and graphically represent the growth of higher plants [20]. In this paper we continue developing the framework introduced in [21], which make use of the topology of membrane structures to model the morphology ...

L-systems in Geometric Modeling

open access: yes, 2010
We show that parametric context-sensitive L-systems with affine geometry interpretation provide a succinct description of some of the most fundamental algorithms of geometric modeling of curves.

Analytical Solution for facilitated transport across a membrane [PDF]

open access: yes, 2002
An analytical expression for the facilitation factor of component A across a liquid membrane is derived in case of an instantaneous reaction A(g)+B(l)AB(l) inside the liquid membrane.

Negative differential response in chemical reactions

open access: yesNew Journal of Physics, 2019
Reaction currents in chemical networks usually increase when increasing their driving affinities. But far from equilibrium the opposite can also happen. We find that such negative differential response (NDR) occurs in reaction schemes of major biological

Bruceine D Identified as a Drug Candidate against Breast Cancer by a Novel Drug Selection Pipeline and Cell Viability Assay

open access: yesPharmaceuticals, 2022
The multi-target effects of natural products allow us to fight complex diseases like cancer on multiple fronts. Unlike docking techniques, network-based approaches such as genome-scale metabolic modelling can capture multi-target effects.

Symbolic software for separation of variables in the Hamilton-Jacobi equation for the L-systems

open access: yes, 2005
We discuss computer implementation of the known algorithm of finding separation coordinates for the special class of orthogonal separable systems called L-systems or Benenti systems.Comment: 13 pages, LaTex File.
