Global distribution of avian plumage coloration and patterning: the relative influence of climate, ecology, and sexual selection

Ecography, EarlyView.
Animal coloration exhibits substantial biogeographic variation, reflecting complex adaptations to both abiotic and biotic environments. Although the evolutionary mechanisms underlying avian plumage coloration have been widely studied, geographic variation in plumage patterning has received far less attention.

Optimising the Eco‐Friendly Extraction of Carotenoids From Gac Fruit: A Sustainable Solution for Natural Red Food Colourants

Food Chemistry International, EarlyView.
Gac fruit's high carotenoid content, especially in the aril, makes it an excellent natural red pigment source for food applications, offering a safer alternative to synthetic dyes. Ethanol extraction achieved the highest overall pigment recovery (89.53%), whereas ethyl lactate extraction yielded the highest levels of total carotenoids, β‐carotene ...

Studies on the Nutritional, Functional, Textural, and Sensory Characteristics of Finger and Barnyard Millet‐Incorporated Nuggets

Food Chemistry International, EarlyView.
The graphic illustrates the development of nuggets traditionally known as “wari” prepared with whole green grams and composite flour barnyard millet var. (PRJ‐1) and finger millet var. (VL‐M‐380) in a 1:1 ratio. The addition of millet significantly improved the nutritional value of nuggets, providing higher levels of protein, carbohydrates, fiber ...

Spirobifluorene fusion in multiple resonance frameworks enables efficient pure‐red OLEDs with narrowband emission and suppressed efficiency roll‐off

FlexMat, EarlyView.
An orthogonal spirobifluorene‐fusion strategy is introduced for B/N/O‐alternated MR frameworks, enabling improved kRISC (5.46 × 103 s−1), high ΦPL (97%), and narrow‐band pure‐red emission. Vacuum‐evaporated OLEDs incorporating this emitter achieve an EQEmax >40% (FWHM = 36 nm) and exhibit exceptionally low efficiency roll‐off at high luminance ...

Chromatic Aberration in Digital Photomicrographs from Microscopes Requiring Compensating Eyepieces

, 2004
Chromatic aberrations are defects in an imaging system caused by the fact that different wavelengths or colors of light are refracted by different amounts. There are two types of chromatic aberration: longitudinal and lateral.
