On the Properties of the Reaction Counts Chemical Master Equation [PDF]

open access: yes, 2019
The reaction counts chemical master equation (CME) is a high-dimensional variant of the classical population counts CME. In the reaction counts CME setting, we count the reactions which have fired over time rather than monitoring the population state ...

A Probabilistic Classification Procedure Based on Response Time Analysis Towards a Quick Pre-Diagnosis of Student’s Attention Deficit

open access: yesMathematics, 2019
A classification methodology based on an experimental study is proposed towards a fast pre-diagnosis of attention deficit. Our sample consisted of school-aged children between 8 and 12 years from Valencia, Spain. The study was based on the response time (

Thinking Outside the Block: External Focus of Attention Improves Reaction Times and Movement Preparation Times in Collegiate Track Sprinters

open access: yesSports, 2018
While focusing attention on external cues (EF) has been shown to enhance performance track and field coaches tend to provide instructions that promote internal focus of attention (IF) during block starts.

Peroneal reaction time after ankle sprain: a systematic review and meta-analysis.

open access: yesMedicine & Science in Sports & Exercise, 2014
BACKGROUND Many studies have examined the temporal response of the peroneal muscles to sudden inversion perturbation in patients with a previous ankle sprain.

Reaction Time for Trimolecular Reactions in Compartment-based Reaction-Diffusion Models [PDF]

open access: yesarXiv, 2016
Trimolecular reaction models are investigated in the compartment-based (lattice-based) framework for stochastic reaction-diffusion modelling. The formulae for the first collision time and the mean reaction time are derived for the case where three molecules are present in the solution.

On the Continuum Time Limit of Reaction-Diffusion Systems

open access: yes, 2013
The parity conserving branching-annihilating random walk (pc-BARW) model is a reaction-diffusion system on a lattice where particles can branch into $m$ offsprings with even $m$ and hop to neighboring sites. If two or more particles land on the same site,

Optimal multisensory decision-making in a reaction-time task

open access: yeseLife, 2014
Humans and animals can integrate sensory evidence from various sources to make decisions in a statistically near-optimal manner, provided that the stimulus presentation time is fixed across trials.

Decay Process for Three - Species Reaction - Diffusion System

open access: yes, 1999
We propose the deterministic rate equation of three-species in the reaction - diffusion system. For this case, our purpose is to carry out the decay process in our three-species reaction-diffusion model of the form $A+B+C\to D$.
