Tω as a Stable Universal Domain
2014
Electronical Notes in Theoretical Computer Science
We investigate the properties of stable retracts and introduce a new domain named a conditionally complete DI-domain (a CCDI-domain for short). ...
Plotkin noticed that T ω , the cartesian product of ω copies of the 3 elements flat domain of Boolean, is a universal domain, where "universal" means that the retracts of T ω in Scott's continuous semantics ...
Each DI-domain is equivalent to a stable event structure and the category of DI-domains (resp. ωDI-domains) with stable functions is cartesian closed [13] . One see that T ω is also an ωDI-domain. ...

Reducibility of domain representations and Cantor–Weihrauch domain representations
2008
Mathematical Structures in Computer Science
To illustrate the framework, we consider some domain representations of real numbers and show that the usual interval domain representation, which is universal among dense representations, does not reduce ...
We show that notions of admissibility, considered both for domains and within Weihrauch's TTE, are universality concepts in the appropriate spectra. ...

Theoretical Computer Science
In this paper dI-domains are enriched by a family of projections which assign to each point a sequence of canonical approximations. ...
Moreover, it is proved that the space of retractions in an exponent @ is a retract of this. Both results together provide new models of Amadio-Longo's extension A/$ of the i-calculus. ...

This short paper contains a non-trivial proof of a result on the
structural property of retractions on DI-domains. ...
The result states
that every reflexive DI-domain’s universal retractions form a DI-
domain isomorphic to (N* U {oo},|), where | is the divisibility

This model differs from the models of McCracken, Scott, etc., in that the types are interpreted (quite pleasingly) as domains rather than closures or finitary projections on a universal domain. ...

Interaction of the cyclic-di-GMP binding protein FimX and the Type 4 pilus assembly ATPase promotes pilus assembly

PLoS Pathogens
These opposing ATPase activities must be coordinated and T4P assembly limited to one pole for bacteria to show directional movement. How this occurs is still incompletely understood. ...
Mutated alleles of FimX that no longer bind c-di-GMP do not allow rapid T4P assembly in these assays. ...
