The SIR dynamic model of infectious disease transmission and its analogy with chemical kinetics [PDF]
PeerJ Physical Chemistry, 2020 Mathematical models of the dynamics of infectious disease transmission are used to forecast epidemics and assess mitigation strategies. In this article, we highlight the analogy between the dynamics of disease transmission and chemical reaction kinetics ...

Uncertainties in Galactic Chemical Evolution Models [PDF]
, 2016 We use a simple one-zone galactic chemical evolution model to quantify the uncertainties generated by the input parameters in numerical predictions for a galaxy with properties similar to those of the Milky Way.

Sensitivity analyses of dense cloud chemical models [PDF]
, 2010 Because of new telescopes that will dramatically improve our knowledge of the interstellar medium, chemical models will have to be used to simulate the chemistry of many regions with diverse properties.

Simple models of the chemical field around swimming plankton [PDF]
, 2010 International audienceThe chemical field around swimming plankton depends on the swimming style and speed of the organism and the processes affecting uptake or exudation of chemicals by the organism.

Modification of N-terminal α-amine of proteins via biomimetic ortho-quinone-mediated oxidation
Nature Communications, 2021 Methods for selective modification of the N-terminus of proteins are of high interest, but mostly require specific amino acid residues. Here, the authors report a selective and fast method for N-terminal modification of proteins based on quinone-mediated

Galaxy chemical evolution models: The role of molecular gas formation [PDF]
, 2017 In our classical grid of multiphase chemical evolution models, star formation in the disc occurs in two steps: first, molecular gas forms, and then stars are created by cloud-cloud collisions or interactions of massive stars with the surrounding ...

Modelling the Chemical Evolution [PDF]
Proceedings of the International Astronomical Union, 2009 AbstractAdvanced observational facilities allow to trace back the chemical evolution of the Universe, on the one hand, from local objects of different ages and, secondly, by direct observations of redshifted objects. The chemical enrichment serves as one of the cornerstones of cosmological evolution.

Quasi-Chemical Theory and Implicit Solvent Models for Simulations [PDF]
, 1999 A statistical thermodynamic development is given of a new implicit solvent model that avoids the traditional system size limitations of computer simulation of macromolecular solutions with periodic boundary conditions.

PNNARMA model: an alternative to phenomenological models in chemical reactors [PDF]
, 2001 This paper is focused on the development of non-linear neural models able to provide appropriate predictions when acting as process simulators. Parallel identification models can be used for this purpose.
