On RAF Sets and Autocatalytic Cycles in Random Reaction Networks

open access: yes, 2014
The emergence of autocatalytic sets of molecules seems to have played an important role in the origin of life context. Although the possibility to reproduce this emergence in laboratory has received considerable attention, this is still far from being ...

Computing F-index, coindex and Zagreb polynomials of the kth generalized transformation graphs

open access: yesHeliyon, 2020
In chemical graph theory, forgotten topological index or F-index plays a crucial role to collect information about the properties of chemical compounds. The kth generalized transformation graphs of a molecular graph preserve the entire information on the

Mathematics at the eve of a historic transition in biology

open access: yes, 2017
A century ago physicists and mathematicians worked in tandem and established quantum mechanism. Indeed, algebras, partial differential equations, group theory, and functional analysis underpin the foundation of quantum mechanism.

Finding weakly reversible realizations of chemical reaction networks using optimization

open access: yes, 2011
An algorithm is given in this paper for the computation of dynamically equivalent weakly reversible realizations with the maximal number of reactions, for chemical reaction networks (CRNs) with mass action kinetics.

GLC actors, artificial chemical connectomes, topological issues and knots [PDF]

open access: yes, 2013
Based on graphic lambda calculus, we propose a program for a new model of asynchronous distributed computing, inspired from Hewitt Actor Model, as well as several investigation paths, concerning how one may graft lambda calculus and knot ...

On physical analysis of phthalocyanine iron (II) using topological descriptor and curve fitting models

open access: yesScientific Reports
A new area of applied chemistry called chemical graph theory uses combinatorial techniques to explain the complex interactions between atoms and bonds in chemical systems. This work investigates the use of edge partitions to decipher molecular connection

Steiner distance in chemical graph theory

open access: yes, 2021
Steiner distance dG(S) is a natural generalization of the concept of distance in a graph. For a connected graph G of order at least 2 and S ⊆ V (G), dG(S) is equal to the minimum size among all connected subgraphs whose vertex sets are equal to the set S.

A graph theory-based algorithm for the reduction of atmospheric chemical mechanisms

open access: yesPNAS Nexus
Abstract The atmospheric chemistry of volatile organic compounds (VOC) has a major influence on atmospheric pollutants and particle formation. Accurate modeling of this chemistry is essential for air quality models. Complete representations of VOC oxidation chemistry are far too large for spatiotemporal simulations of the atmosphere ...
