Colour–colour and colour–magnitude diagrams for hot Jupiters [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2020
ABSTRACT We use ground-based and space-based eclipse measurements for the near-infrared (IR) bands (JHKs) and Spitzer 3.6- and 4.5-μm bands to construct colour–colour and colour–magnitude diagrams for hot Jupiters. We compare the results with previous observations of substellar objects and find that hot Jupiters, when corrected for their

Assessment of Sensory and Texture Profiles of Grape Seeds at Real Maturity Stages Using Image Analysis

open access: yesFoods, 2021
The usefulness of digital image analysis in estimating sensory attributes of grape seeds in relation to maturation level was evaluated for the first time. Seeds from Syrah grapes harvested throughout the ripening period were grouped according to maturity

Research Progress in Imaging Technology for Assessing Quality in Wine Grapes and Seeds

open access: yesFoods, 2022
The chemical composition of wine grapes changes qualitatively and quantitatively during the ripening process. In addition to the sugar content, which determines the alcohol content of the wine, it is necessary to consider the phenolic composition of the ...

Different colour predictions of facial preference by Caucasian and Chinese observers

open access: yesScientific Reports, 2022
Facial colour characteristics convey vital personal information and influence social interactions and mate choices as contributing factors to perceived beauty, health, and age. How various colour characteristics affect facial preference and whether there

Colour calibration for colour reproduction [PDF]

open access: yes2000 IEEE International Symposium on Circuits and Systems. Emerging Technologies for the 21st Century. Proceedings (IEEE Cat No.00CH36353), 2002
Due to the proliferation of low-cost colour devices (digital colour cameras, scanners, printers etc.) during the last few years, colour calibration has become an important issue. Such devices should faithfully reproduce colour images, but experience shows they don't.

Optimization of Protein Extraction of Oenological Interest from Grape Seed Meal Using Design of Experiments and Response Surface Methodology

open access: yesFoods, 2021
After grape processing, large amounts of seeds are produced as a side product. Grape seeds are rich in proteins that could be extracted and revalorized by the wine industry due to their high techno-functional value for modulating quality features of red ...

Colour Vision: Colouring the Dark [PDF]

open access: yesCurrent Biology, 2003
Humans lose colour vision at night and it has often been assumed that this happens to other animals as well. It is not true of nocturnal moths, however: a recent study has shown that the elephant hawk moth makes use of trichromatic colour vision when seeking flowers by starlight.
