Further screening of SNP loci of eggshell translucency related genes and evaluation of genetic effects

open access: yesPoultry Science
: Eggshell translucency is a widespread issue in the field of egg quality. Previous research has established that the heritability of eggshell translucency is relatively low or moderate.

Translucency and the perception of shape

open access: yesJournal of Vision, 2017
Previous studies have shown that the perceived three-dimensional (3D) shape of objects depends on their material composition. The majority of this work has focused on glossy, flat-matte, or velvety materials. Here, we studied perceived 3D shape of translucent materials. We manipulated the spatial frequency of surface relief perturbations of translucent

Game theory with translucent players [PDF]

open access: yesInternational Journal of Game Theory, 2018
A traditional assumption in game theory is that players are opaque to one another---if a player changes strategies, then this change in strategies does not affect the choice of other players' strategies. In many situations this is an unrealistic assumption.

Comparative metabolomics reveals eggshell translucency formation using LC-MS Analysis

open access: yesPoultry Science
Eggshell translucency is the common problem on eggshell that become more severe with age. They are important because it influence consumer preferences and the economic value of eggs.

Translucent eggs of laying hens: a review

open access: yesPoultry Science
: Eggshell quality is a significant characteristic that influences consumer preferences. Eggshell translucency is a common defect in the appearance of eggshells, which are characterized by gray spots that are visible to the naked eye under natural light.

Effect of Accelerated Artificial Aging on Translucency of Methacrylate and Silorane-Based Composite Resins

open access: yesFrontiers in Dentistry, 2016
Objectives: Composite restorations must have tooth-like optical properties namely color and translucency and maintain them for a long time. This study aimed to compare the effect of accelerated artificial aging (AAA) on the translucency of three ...
