Short relaxation times but long transient times in both simple and complex reaction networks [PDF]

open access: yes, 2015
When relaxation towards an equilibrium or steady state is exponential at large times, one usually considers that the associated relaxation time $\tau$, i.e., the inverse of that decay rate, is the longest characteristic time in the system.

Behavioral estimates of interhemispheric transmission time and the signal detection method: A reappraisal [PDF]

open access: yes, 1994
On the basis of a review of the literature, Bashore (1981) concluded that only simple reaction time experiments with manual responses yielded consistent behavioral estimates of interhemispheric transmission time.

The impact of fencing training symmetrisation on simple reaction time

open access: yesBiomedical Human Kinetics, 2021
Study aim: The symmetrisation of movements can be a way to develop individual coordinative skills, and to prevent the occur-rence of injuries. For this reason, in this study an attempt was made to evaluate and compare simple reaction time and movement ...

Photochemical synthesis of a “cage” compound in a microreactor: Rigorous comparison with a batch photoreactor [PDF]

open access: yes, 2013
An intramolecular [2 + 2] photocycloaddition is performed in a microphotoreactor (0.81 mL) built by winding FEP tubing around a commercially available Pyrex immersion well in which a medium pressure mercury lamp is inserted.

Systematic front distortion and presence of consecutive fronts in a precipitation system [PDF]

open access: yes, 2006
A new simple reaction-diffusion system is presented focusing on pattern formation phenomena as consecutive precipitation fronts and distortion of the precipitation front.The chemical system investigated here is based on the amphoteric property of ...

Microspinning: Local Surface Mixing via Rotation of Magnetic Microparticles for Efficient Small-Volume Bioassays [PDF]

open access: yes, 2020
The need for high-throughput screening has led to the miniaturization of the reaction volume of the chamber in bioassays. As the reactor gets smaller, surface tension dominates the gravitational or inertial force, and mixing efficiency decreases in small-

Suppression of thermally activated escape by heating [PDF]

open access: yes, 2009
The problem of thermally activated escape over a potential barrier is solved by means of path integrals for one-dimensional reaction dynamics with very general time dependences. For a suitably chosen but still quite simple static potential landscape, the

Predicting Fluid Intelligence by Components of Reaction Time Distributions from Simple Choice Reaction Time Tasks

open access: yesJournal of Intelligence, 2016
Mean reaction times (RT) and the intra-subject variability of RT in simple RT tasks have been shown to predict higher-order cognitive abilities measured with psychometric intelligence tests.

The Neurobehavioural Evaluation in Schizophrenics: A Comparative Study [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2013
Background: The simple reaction time task assesses the ability of the subject to respond to an external cue and to retrieve a reward. The reaction time provides an indirect index of the processing capability of the central nervous system and a simple

Influence of practice on visual reaction time

open access: yesJournal of Mahatma Gandhi Institute of Medical Sciences, 2014
Background: The present study was aimed to see the effect of practice on visual information processing speed. Reaction time is one of the important physiological parameters, which gives information how fast and quickly person responses.
