We model differences among agents in their ability to recognize temporal patterns of prices. Using the concept of DeBruijn sequences in two dynamic models of markets, we demonstrate the existence of equilibria in which prices fluctuate in a pattern that is independent of the fundamentals and that can be recognized only by the more competent agents.

It is shown that Darwiche and Pearl's postulates imply an interesting property, not noticed by the authors. In [?], Darwiche and Pearl propose postulates for iterated revisions, noted (R*1) to (R*6) and (C1) to (C4). In particular, the postulate (C3) reads: (C3) If Ψ • α |= µ, then (Ψ • µ) • α |= µ. It will be shown that, in the presence (R*1) to (R*6), (C1) and (C3) imply: (* *) If Ψ • α |= µ,...

in eukaryotes, vesicle trafficking is regulated by the small monomeric gtpases of the rab protein family. rab11, (a subfamily of the ypt/rab gene family) an evolutionarily conserved, ubiquitously expressed subfamily of small monomeric rab gtpases, has been implicated in regulating vesicular trafficking through the recycling of endosomal compartment. in an earlier communication, we have shown th...
