Ca

There will be an in-person meeting of the marketing subcommittee on Tuesday afternoon of Jan 27, 1999 at the San Francisco CA Airport Marriott.

There are swift-flowing rivers which dash through jagged cañons; and there are enormous plains, which in winter are white with snow, and in summer are grey with saline alkali dust.

Calcium is a chemical element with the symbol Ca.

Calcium is the name for the element with atomic number 20 and is represented by the symbol Ca. It is a member of the alkaline earth metal group.

Until 1922 the language of Turkey was known as "Osmanlıca" or Ottoman Turkish.

BTW: Of course the rules were parametrised, so any totalistic 2-dimensional 9-neighbourhood CA could be run.

The new CA is a modification of Fredkin's earlier SALT architecture in which every cell is identified as either even or odd - as in sodium and chlorine in a salt crystal hence the name. The state of each cell is either up or down and the development rule simple takes account of states of odd and even neighbours. The up-date at each time step simply takes the form of a swap of the states of diagonally related cells. SALT CAs are reversible and capable of universal computation and are conjectured to be capable of universal construction in the sense of Von Neumann.

I assume we are speaking of a single rule CA (one rule for every cell).

Well-designed CAs will create a trust hierarchy, which consists of a root with a number of subroots, to further enhance protection of the private key.
