Expressible Inspections

A decision maker needs predictions about the realization of a repeated experiment in each period. An expert provides a theory that, conditional on each finite history of outcomes, supplies a probabilistic prediction about the next outcome. However, there may be false experts without any knowledge of the data-generating process who deliver theories strategically. Hence, empirical tests for predi...

Expressible Semantics for Expressible Counterfactuals

Lewis (1981) showed the equivalence between two dominant semantic frameworks for counterfactuals: ordering semantics, which relies on orders between possible worlds, and premise semantics, which relies on sets of propositions (so-called ordering sources). I define a natural, restricted version of premise semantics, expressible premise semantics, which is based on ordering sources containing onl...

Functionally Expressible Multidistances

In this paper we deal with the problem of aggregating pairwise distance values in order to obtain a multi-argument distance function. After introducing the concept of functionally expressible multidistance, several essential types of multidimensional aggregation functions are considered to construct such kind of multidistances. An example of non functionally expressible multidistance is exhibited.

Expressible molecular colonies

Carrying out polymerase chain reaction in a gel layer generates a 2-D pattern of DNA colonies comprising pure genetic clones. Here we demonstrate that transcription, translation and protein folding can be performed in the same gel. The resulting nucleoprotein colonies mimic living cells by serving as compartments in which the synthesized RNAs and proteins co-localize with their templates. Yet, ...
