A new study of camouflage in quail shows that individual birds know the appearance of their own eggs and select backgrounds that maximise concealment.

Our research is within the area of artificial intelligence and multiagent system. More specifically, we are interested in addressing robustness problems in trust and reputation systems so that buying agents are able to accurately model the reputation of selling agents even with the existence of various unfair rating attacks from other dishonest buyers (called advisors) [Zhang and Cohen, 2008]. ...

Camouflage is found in a wide range of species living in numerous habitat types, offering protection from visually guided predators. This includes many species from the intertidal zone, which must cope with background types diverse in appearance and with multiple predator groups foraging at high and low tide. Many animals are capable of either relatively slow (hours, days, weeks) or rapid (seco...

The formation of groups is a common strategy to avoid predation in animals, and recent research has indicated that there may be interactions between some forms of defensive coloration, notably high-contrast 'dazzle camouflage', and one of the proposed benefits of grouping: the confusion effect. However, research into the benefits of dazzle camouflage has largely used targets moving with constan...

BACKGROUND Filler materials are gaining popularity in nonsurgical rhinoplasty the major advantages are the ability to camouflage the surface deformities, and also the soft and malleable consistency while the major drawback of the safe fillers such as hyaluronic acid is short durability. In this study, we evaluated the injectable cartilage shaving as an autologous filler material for correction...
