C-element desirable effect. For example, using the ternary majority function defined as does not lead to the ternary C-element specified by the truth table, if the sum formula_6 is not split into pairs. However, even without such a splitting two ternary majority functions are suitable for building a ternary inclusive OR gate. Note that both the Maevsky and Tsirlin circuits are based actually on so-called David cell. Its fast transistor-level implementation is used in the semistatic C-element proposed. Yet another semistatic circuit using pass transistors (actually MUX 2:1) has been proposed. Other technologies suitable for realizing asynchronous primitives including C-element, are:
C-rich stability element been mapped to a pyrimidine-rich segment of its 3' UTR. This region confers stability by directing the assembly of a specific alpha ribonucleoprotein complex at this site. Subsequently Holcik and Liebhaber identified three other highly stable eukaryotic mRNAs that assemble the alpha globin protein complex at homologous pyrimidine-rich regions within their 3'UTRs (rabbit lipoxygenase, rat tyrosine hydroxylase, and human alpha(I)-collagen). There is some debate as to the number and identity of trans-acting factors recruited to the C-rich element. However the alpha globin poly(C)-binding protein (alphaCP) is agreed to be the core constituent of what is known as the alpha complex.
