Exploiting product molecule number to consider reaction rate fluctuation in elementary reactions [PDF]
, 2019 In many chemical reactions, reaction rate fluctuation is inevitable. Reaction rates are different whenever chemical reaction occurs due to their dependence on the number of reaction events or the product number. As such, understanding the impact of rate fluctuation on product number counting statistics is of the utmost importance when developing a ...

Modelling Chemical Reasoning to Predict Reactions [PDF]
Chem. Eur. J. 2017, 23, 6118-6128, 2016 The ability to reason beyond established knowledge allows Organic Chemists to solve synthetic problems and to invent novel transformations. Here, we propose a model which mimics chemical reasoning and formalises reaction prediction as finding missing links in a knowledge graph. We have constructed a knowledge graph containing 14.4 million molecules and

Stirring Speeds Up Chemical Reaction [PDF]
, 2021 We consider absorbing chemical reactions in a fluid flow modeled by the coupled advection-reaction-diffusion equations. In these systems, the interplay between chemical diffusion and fluid transportation causes the enhanced dissipation phenomenon. We show that the enhanced dissipation time scale, together with the reaction coupling strength, determines

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 ...

Inhibition of the activity of pro-inflammatory secretory phospholipase A2 by acute phase proteins
Mediators of Inflammation, 1996 Pro-Inflammatory non-pancreatic phospholipase A2 (sPLA2) is markedly over-expressed in acute systemic and chronic local inflammatory processes. Since in acute phase reaction sPLA2 is often over-expressed simultaneously with acute phase proteins (APP), it

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.
