Colonies of the bioluminescent marine bacterium Vibrio fischeri. This photograph of the colonies growing on agar (left) was taken with a light source. The photograph of the colonies on the right was taken using their own bioluminescence as a light source.National Science Foundation-supported researchers are studying the relationship between the Hawaiian sepiolid squid, Euprymna scolopes, and its luminous bacterial partner Vibrio fischeri. Although all animals have beneficial associations with microbes, the association between E. scolopes and V. fischeri is the only experimental model available to biologists so far.

PAJ: A Journal of Performance and Art 24.2 (2002) 10-11 // --> [Access article in PDF] Didactic Video (1975) Woody Vasulka [Figures] These time segments belong to a larger work titled Time/Energy Structure of the Electronic Image, dating from 1974 through 1975. The images are produced on a scan processor (Rutt/Etra Model-4, Rutt Electrophysics Inc.), a tool providing various means of reprogramming electromagnetic conditions around its display (cathode ray tube or CT).
The majority of images, still or moving, are based on their capture from the visible world with the help of the camera obscura principle through a process involving the interaction of light with a photo-emulsion surface. The conversion of light into a code occurs simultaneously at each part of the emulsion in exposure time. Contrary to this, the conversion of light into energy potentials during electronic image forming is achieved sequentially, giving particular significance to the construction of the referential time frame. (The single value on the pick-up tube has to possess exact time coordinates in order to be reproduced in the identical position on the display.) The organization of energy components even in a television camera is of course provided by the camera obscura present in front of the image pick-up tube.
The possibility of disregarding this organizational principle and realizing instead a total absence of such a process in certain modes of electronic image forming has interested me the most. The result has been an inevitable descent into the analysis of smaller and smaller time-sequences, a process necessary to understanding wave formations, their components, and the process of their synthesis and programmability. To me this indicates a point of departure from light/space image models closely linked to and dependent upon visual-perceptual references and maintained through media based on the camera obscura principle. It now becomes possible to move precisely and directly between a conceptual model and a constructed image. This opens a new self-generating cycle of design within consciousness and the eventual construction of new realities without the necessity of external referents as a means of control.

@Nancy Bradshaw Hi, adding to @erutherford When page 1 (the front) of the Grave Registration is on your right, the matching page 2 (the back side) will be +1 in the reference pages. Go ahead and use the Burial place and Cemetery Name on the +1 reference. When page 2 (the back side) is on your left, the matching page 1 will be -1 in the reference pages -- this record has been or will be indexed by another indexer. Mark this image (the left-hand image in your batch) NNED. I hope I haven't thoroughly confused you with my explanation. Give it a try and email me if you like, I'm on Utah time and I check community discussions every day

Quantization bits along each color axis for the inverse colormap, specified as a positive integer. If Qe is less than Qm, then dithering cannot be performed and the dither function returns an undithered indexed image in X.
Quantization bits for the color space error calculations, specified as a positive integer. If Qe is less than Qm, then dithering cannot be performed and the dither function returns an undithered indexed image in X.
Indexed image, returned as an m-by-n matrix of nonnegative integers. If the length of map is less than or equal to 256, then the output image is of class uint8. Otherwise, the output image is of class uint16. The value 0 in the output array X corresponds to the first color in the colormap. 59ce067264
