Virtual logic - The Flagg Resolution
Consider the statement: J= ‘This statement is false.’ If J is true then J states that J is false. If J is false then J states that J is true. Thus we can write J = Not J. One might shun such a statement, but perhaps there is a way to deal with it. One solution that has been proposed is to say that J has a new kind of truth value, neither true nor false, and to devise a logic with more than two ...

Here, we measured the signaling dynamics of the morphogen Dpp, one of several Drosophila factors controlling morphogenetic growth, in the developing eye. In this tissue, the Dpp expression domain advances from the posterior to the anterior tissue edge. In front of this moving morphogen s...
