Strong defocusing of molecular reaction times results from an interplay of geometry and reaction control [PDF]
Commun. Chem. 1, 96 (2018), 2019 Text-book concepts of diffusion- versus kinetic-control are well-defined for reaction-kinetics involving macroscopic concentrations of diffusive reactants that are adequately described by rate-constants -- the inverse of the mean-first-passage-time to the reaction-event. In contradistinction, an open important question is whether the mean-first-passage-

Phase Space Analysis of Fluorine-Oxygen-Nitrogen Network and Energy Generation in Flourine-Oxygen Reaction [PDF]
arXiv, 2023 Reaction network of fluorine-18, oxygen-15 and nitrogen-15 is considered for its temperature dependent energy output. The main reactions for generation and annihilation of oxygen and fluorine are coupled in the reaction equations while nitrogen is produced as a decay product.

A Query-Response Causal Analysis of Reaction Events in Biochemical Reaction Networks [PDF]
arXiv, 2022 The stochastic kinetics of BRN are described by a chemical master equation (CME) and the underlying laws of mass action. The CME must be usually solved numerically by generating enough traces of random reaction events. The resulting event-time series can be evaluated statistically to identify, for example, the reaction clusters, rare reaction events ...

Green Chemical Engineering, 2021 Intramolecular acid-base cooperative catalysis is a powerful strategy to promote the nucleophilic additions in synthetic chemistry, since both substrates and nucleophiles can be activated simultaneously, yielding a lower energy reaction pathway. However,

Reversible Graph Neural Network-based Reaction Distribution Learning for Multiple Appropriate Facial Reactions Generation [PDF]
arXiv, 2023 Generating facial reactions in a human-human dyadic interaction is complex and highly dependent on the context since more than one facial reactions can be appropriate for the speaker's behaviour. This has challenged existing machine learning (ML) methods, whose training strategies enforce models to reproduce a specific (not multiple) facial reaction ...

Correlated Energy Uncertainties in Reaction Rate Calculations [PDF]
A&A 642, A41 (2020), 2020 Context. Monte Carlo methods can be used to evaluate the uncertainty of a reaction rate that arises from many uncertain nuclear inputs. However, until now no attempt has been made to find the effect of correlated energy uncertainties in input resonance parameters. Aims. To investigate the impact of correlated energy uncertainties on reaction rates.
