Correctly rendering non-refractive transparent surfaces with core OpenGL functionality [9] has the vexing requirements of depth-sorted traversal and nonintersecting polygons. This is frustrating for most application developers using OpenGL because the natural order of scene traversal (usually one object at a time) rarely satisfies these requirements. Objects can be complex, with their own trans...

How can algebraic and coalgebraic specifications be integrated? How can behavioral equivalence be addressed in an algebraic specification language? The hidden-sorted approach, originating in work of Goguen and Meseguer in the early 80’s, and further developed into the hidden-sorted logic approach by researchers at Oxford, UC San Diego, and Kanazawa offers some attractive answers, and has been i...

Added the 2 new JPAII activities in WP5 to the Conclusions References amalgamated, sorted into alphabetical order and moved to end of document. Additional web links added.

Posttranslational processing of many proteins is essential to the synthesis of fully functional molecules. The ELH (egg-laying hormone) prohormone is cleaved by endoproteases in a specific order at a variety of basic residue processing sites to produce mature peptides. The prohormone is first cleaved at a unique tetrabasic site liberating two intermediates (amino and carboxy) which are sorted t...

This is a formalization of the soundness and completeness proper-ties for various efficient encodings of sorts in unsorted first-order logicused by Isabelle’s Sledgehammer tool.The results are reported in [1, §2,3] and the formalization itself ispresented in [2, §3–5]. Essentially, the encodings proceed as follows:a many-sorted problem is decorated with (as few as possib...
