Modest Theory of Short Chains
We analyse here the monadic theory of the rational order, the monadic theory of the real line with quantification over "small" subsets and models of these theories. We prove that the results are in some sense the best possible. ?0. Introduction. A chain is a linearly ordered set. A chain is short iff it embeds neither Wi nor O1. Shortness is expressible in the monadic language of order. For con...
متن کاملA short history of a short RNA
The intellectual backdrop motivating our effort to clone lin-4 (Lee et al., 1993) had nothing to do with questions about noncoding RNAs or antisense gene regulation. We were simply curious about an interesting worm mutant, and everything we found out about it was unexpected. We consider ourselves very lucky to happen to have chosen lin-4 to study. In fact, good fortune appeared at many steps be...

defects opposite to those of lin-4(e912). Precisely the These opposite developmental timing defects of lin-4 Harvard Medical School and lin-14 mutants, and the fact that loss of lin-14 is Department of Molecular Biology epistatic to lin-4(e912), suggested that the lin-4(e912) Massachusetts General Hospital mutation resulted in an excess of lin-14 activity. So lin-4 Boston, Massachusetts 02114 m...
متن کاملModest Theory of Short Chains. I
This is the first part of a two part work on the monadic theory of short orders (embedding neither w1 nor w1*). This part provides the technical groundwork for decidability results. Other applications are possible. ?0. Introduction. A chain is a linearly ordered set. A chain is short iff it embeds neither o)1 nor Oj1. A chain is Specker iff it does not embed any uncountable subchain of the real...
متن کاملCharge Tunneling along Short Oligoglycine Chains.
This work examines charge transport (CT) through self-assembled monolayers (SAMs) of oligoglycines having an N-terminal cysteine group that anchors the molecule to a gold substrate, and demonstrate that CT is rapid (relative to SAMs of n-alkanethiolates). Comparisons of rates of charge transport-using junctions with the structure Au(TS)/SAM//Ga2O3/EGaIn (across these SAMs of oligoglycines, and ...
