A deep learning framework for accurate reaction prediction and its application on high-throughput experimentation data

open access: yesJournal of Cheminformatics, 2023
In recent years, it has been seen that artificial intelligence (AI) starts to bring revolutionary changes to chemical synthesis. However, the lack of suitable ways of representing chemical reactions and the scarceness of reaction data has limited the ...

Improving Chemical Reaction Prediction with Unlabeled Data

open access: yesMolecules, 2022
Predicting products of organic chemical reactions is useful in chemical sciences, especially when one or more reactants are new organics. However, the performance of traditional learning models heavily relies on high-quality labeled data.

Identification of functional differences in metabolic networks using comparative genomics and constraint-based models. [PDF]

open access: yesPLoS ONE, 2012
Genome-scale network reconstructions are useful tools for understanding cellular metabolism, and comparisons of such reconstructions can provide insight into metabolic differences between organisms.

A global optimization method for model selection in chemical reactions networks [PDF]

open access: yesComputers & Chemical Engineering, 2016
Model inference is a challenging problem in the analysis of chemical reactions networks. In order to empirically test which, out of a catalogue of proposed kinetic models, is governing a network of chemical reactions, the user can compare the empirical data obtained in one experiment against the theoretical values suggested by the models

Challenges for Kinetics Predictions via Neural Network Potentials: A Wilkinson’s Catalyst Case

open access: yesMolecules, 2023
Ab initio kinetic studies are important to understand and design novel chemical reactions. While the Artificial Force Induced Reaction (AFIR) method provides a convenient and efficient framework for kinetic studies, accurate explorations of reaction path

Persistence and stability of generalized ribosome flow models with time-varying transition rates.

open access: yesPLoS ONE, 2023
In this paper some important qualitative dynamical properties of generalized ribosome flow models are studied. Ribosome flow models known from the literature are generalized by allowing an arbitrary directed network structure between compartments, and by

Mathematical Methods for Modeling Chemical Reaction Networks [PDF]

open access: yes, 2016
Abstract Cancer’s cellular behavior is driven by alterations in the processes that cells use to sense and respond to diverse stimuli. Underlying these processes are a series of chemical processes (enzyme-substrate, protein-protein, etc.).

Autonomous kinetic modeling of biomass pyrolysis using chemical reaction neural networks [PDF]

open access: yesCombustion and Flame, 2022
Modeling the burning processes of biomass such as wood, grass, and crops is crucial for the modeling and prediction of wildland and urban fire behavior. Despite its importance, the burning of solid fuels remains poorly understood, which can be partly attributed to the unknown chemical kinetics of most solid fuels.
