Tableau Recycling
In this paper we improve a model checking algorithm based on the tableau method of Stifling and Walker. The algorithm proves whether a property expressed in the modal mu-calculus holds for a state in a finite transition system. It makes subsequent use of subtableaux which were calculated earlier in the proof run. These aubtab|eaux are reduced to expressions. Examples show that both size of tabl...

Heparin sustains the brain myloid plaque formation can be inhibited by an unlikely culprit, according to work by Scholefield et al. on page 97. The group finds that heparan sulfate (HS)—normally a part of the cell surface and extracellular matrix—functions in cells to slow the production of the plaque components of Alzheimer's disease. Amyloid plaques are aggregates of the amyloid -peptide (A ...
