A Chiton Uses Aragonite Lenses to Form Images
Hundreds of ocelli are embedded in the dorsal shell plates of certain chitons. These ocelli each contain a pigment layer, retina, and lens, but it is unknown whether they provide chitons with spatial vision. It is also unclear whether chiton lenses are made from proteins, like nearly all biological lenses, or from some other material. Electron probe X-ray microanalysis and X-ray diffraction rev...
متن کاملMultifunctionality of chiton biomineralized armor with an integrated visual system.
Nature provides a multitude of examples of multifunctional structural materials in which trade-offs are imposed by conflicting functional requirements. One such example is the biomineralized armor of the chiton Acanthopleura granulata, which incorporates an integrated sensory system that includes hundreds of eyes with aragonite-based lenses. We use optical experiments to demonstrate that these ...
متن کاملFormation in Chrysochromulina Chiton
The normal form of the species has been compared with a deviant form and the processes of scale production in both more fully studied. The deviation is shown to be genetically based, possibly a mutation, of which the main structural expression is loss of capacity to develop the normal outer layer of material on each scale. The large scales also lack rims, a flange on the back giving a spurious ...
متن کاملAutobiographical Brand Images Give a Higher Chance to False Memory as Compared to Neutral Images
Consumers’ prior experiences shape an episodic memory which largely influences their decision-making process. This episodic memory is mainly linked to cognitive and emotional perception and we know that a brand image influences our cognitive and emotional perception. Nevertheless, it has not been well described how autobiographical memories of brand images differ from those of other types of im...
متن کاملUses of Uncalibrated Images to Enrich 3d Models Information
The decrease in costs of semi-professional digital cameras has led to the possibility for everyone to acquire a very detailed description of a scene in a very short time. Unfortunately, the interpretation of the images is usually quite hard, due to the amount of data and the lack of robust and generic image analysis methods. Nevertheless, if a geometric description of the depicted scene is avai...
