A flashing light may not be that flashy: A systematic review on critical fusion frequencies.

open access: yesPLoS ONE, 2022
BackgroundLight pollution could represent one of the main drivers behind the current biodiversity erosion. While the effects of many light components on biodiversity have already been studied, the influence of flicker remains poorly understood.

A deep learning based cognitive model to probe the relation between psychophysics and electrophysiology of flicker stimulus

open access: yesBrain Informatics
The flicker stimulus is a visual stimulus of intermittent illumination. A flicker stimulus can appear flickering or steady to a human subject, depending on the physical parameters associated with the stimulus.

Colorimetry in Nuclear Fusion Research

open access: yes, 2022
0000-0001-5522-3082Colorimetry is a unique technique among research fields. The technique is also utilized in nuclear fusion research. The motivation is to evaluate the wide range of distribution of the deposition layer on the surface of the vacuum ...

Evaluating letter recognition, flicker fusion, and the Talbot-Plateau law using microsecond-duration flashes. [PDF]

open access: yesPLoS ONE, 2015
Four experiments examined the ability of respondents to identify letters that were displayed on an LED array with flashes lasting little more than a microsecond. The first experiment displayed each letter with a single, simultaneous flash of all the dots

Workshop at Data and Planning Center of NIFS in 2003 "Assesment of Fusion R&D" - The Critical Issues of Demonstration Fusion Reactor - [PDF]

open access: yes, 2004
実証炉を構想しそれに至る課題を整理することは、核融合研究開発の現状を評価するうえで最も適切な作業のひとつと考えた。磁場閉じ込めと慣性閉じ込め核融合に共通な課題は経済性の改善である。また、磁場閉じ込めではトカマクもヘリカルも将来性のあるダイバータの開発は共通である。 経済性に関しては先進トカマクや高速点火方式のレーザ慣性核融合の提案が出てきている。さらにダイバータに関しては可動型や外置き型の研究が進められている。これらの要約は添付した。In order to asses the fusion ...

The clinical application of critical flicker fusion frequency in demyelinating optic neuritis

open access: yesAdvances in Ophthalmology Practice and Research, 2021
Purpose: To investigate the application of critical flicker fusion frequency (CFF) in demyelinating optic neuritis (DON). Methods: A cross-sectional study. A total of 127 eyes in 69 DON patients and 63 eyes in 33 healthy control (HC) groups were included

Investigating critical flicker fusion frequency for monitoring gas narcosis in divers.

open access: yes, 2020
Critical flicker fusion frequency (CFFF) has been used in various studies to measure the cognitive effects of gas mixtures at depth, sometimes with conflicting or apparently paradoxical results.
