Chu I: Cofree Equivalences, Dualities and *-Autonomous Categories

Received We study three comonads derived from the comma construction. The induced coalgebras correspond to the three concepts displayed in the title of the paper. The comonad that yields the-autonomous categories is, in essence, the Chu construction, which has recently awaken much interest in computer science. We describe its couniversal property. It is right adjoint to the inclusion of-autonom...

Lecture Notes on Information Theory Volume I by Po

Preface The reliable transmission of information bearing signals over a noisy communication channel is at the heart of what we call communication. Information theory—founded by Claude E. Shannon in 1948—provides a mathematical framework for the theory of communication; it describes the fundamental limits to how efficiently one can encode information and still be able to recover it with negligib...

Chu Spaces

Po - Spaces

Locally partial-ordered spaces (local po-spaces) have been used to model concurrent systems. We provide equivalences for these spaces by constructing a model category containing the category of local po-spaces. We show the category of simplicial presheaves on local po-spaces can be given Jardine's model structure, in which we identify the weak equivalences between local po-spaces. In the proces...

Jeannette Bigler , Chu

A method is presented for the analysis of fluorescently labeled random amplified polymorphic DNA (FRAPD) fragments. A DNA sequencer and collection and analysis software were used to estimate the sizes of DNA fragments based on their mobilities relative to in-lane size markers. This allowed confident identification and comparison of FRAPD markers both within and between polyacrylamide gels. In c...
