Kepler, a space telescope, looks for planet signatures by measuring tiny decreases in the brightness of stars caused by planets crossing in front of them.
The increased temperature also caused a marked decrease in the QD brightness, which provided a means for in situ heat/temperature sensing and an indicator of the progress of the photo-thermal therapy.
Although there is a slight increase in the turn-on voltage and a decrease in the maximum brightness compared to the reference device, the J– V– L characteristics show that the helicene dopant does not dramatically impact PLED operation or performance.
The radiation is known to vary cyclically with the solar cycle and satellites have been tracking the decrease in brightness of the clouds with the increase of ultraviolet radiation for the last two solar cycles.
Even the long-known solar phenomenon of limb darkening, the gradual decrease in brightness from the centre to the edge of the Sun's disk, has been detected in the component stars of eclipsing binaries.
Because the FITC dye is pH sensitive, the decrease in brightness of the phagosome most likely reflects the acidification of the phagosome by proton pumps [16].
The list had included: Pinatubo-scale eruptions, a small decrease in the sun's brightness at the minimum of the solar cycle, an increase in short-lived pollutant hazes from Asia that stay in the lower atmosphere, and decade-long variations of climate spurred by El Niño and other natural climate movers.
Limb darkening, in astrophysics, gradual decrease in brightness of the disk of the Sun or of another star as observed from its centre to its edge, or limb.
A point spread function (PSF), expressed by Equation (3), can be employed to approximate a small target13, 28, 29, which is basically a connected area with a decrease in brightness from the target center to its edge, as expressed by a Gaussian distribution (Supplementary Note 2 and Supplementary Fig. S1).
At the same time, the star showed a decrease in brightness, beginning at the end of 1971.
