A Characterization of the Brightness Oscillations During Thermonuclear Bursts From 4U 1636-536 [PDF]
, 1999 The discovery of nearly coherent brightness oscillations during thermonuclear X-ray bursts from six neutron-star low-mass X-ray binaries has opened up a new way to study the propagation of thermonuclear burning, and may ultimately lead to greater ...

Influence of Basic Colour Parameters on Colour Memory [PDF]
Tekstilec, 2019 We frequently need to compare two or more colours, and we can rely only on the colour impression from our memory. Colours are not stored in our memories in their actual state and they can gradually be erased.

Brightness Prediction of Large Color Gamut Laser Display Devices
Micromachines, 2023 A brightness-perceived color appearance model tailored for large gamut display devices, exemplified by laser displays, was investigated. Psychophysical experiments on the brightness matching of 30 color stimuli with achromatic white light were conducted ...

Brightness of Synchrotron radiation from Undulators and Bending Magnets [PDF]
, 2014 We consider the maximum of the Wigner distribution (WD) of synchrotron radiation (SR) fields as a possible definition of SR source brightness. Such figure of merit was originally introduced in the SR community by Kim.

Minimising efficiency roll-off in high-brightness perovskite light-emitting diodes
Nature Communications, 2018 Efficiency roll-off is a major issue for most types of light-emitting diodes (LEDs), and its origins remain controversial. Here we present investigations of the efficiency roll-off in perovskite LEDs based on two-dimensional layered perovskites.

Surface Brightness Gradients Produced by the Ring Waves of Star Formation [PDF]
, 1997 We compute surface brightness profiles of galactic disks for outwardly propagating waves of star formation with a view to investigate the stellar populations in ring galaxies. We consider two mechanisms which can create outwardly propagating star forming

Future Prospects: Deep Imaging of Galaxy Outskirts using Telescopes Large and Small
, 2016 The Universe is almost totally unexplored at low surface brightness levels. In spite of great progress in the construction of large telescopes and improvements in the sensitivity of detectors, the limiting surface brightness of imaging observations has ...
