Nineteeth Study: Elijah, Elisha, and Their Fellow-Prophets

Net prophets

Statements that " we have come to do biology in a new way " or " there is a new paradigm in biological research " are now commonplace. Nobody seems to be satisfied by a single good experiment that gives a precise answer to a well formulated question, which was the old way we did biology. On the contrary there is now a belief that a mass attack on parallel fronts can provide a database of all th...

Schedulers are no Prophets

Several formalisms for concurrent computation have been proposed in recent years that incorporate means to express stochastic continuous-time dynamics and non-determinism. In this setting, some obscure phenomena are known to exist, related to the fact that schedulers may yield too pessimistic verification results, since current nondeterminism can surprisingly be resolved based on prophesying th...

Denote the free group on 2 letters by F2 and the SL(2,C)-representation variety of F2 by R = Hom(F2, SL(2,C)). The group SL(2,C) acts on R by conjugation. We construct an isomorphism between the coordinate ring C[SL(2,C)] and the ring of matrix coefficients, providing an additive basis of C[R]SL(2,C) in terms of spin networks. Using a graphical calculus, we determine the symmetries and multipli...

The 12 prophets dataset

The "Ajeijadinho 3D" project is an initiative supported by the University of São Paulo (Museum of Science and Dean of Culture and Extension), which involves the 3D digitization of art works of Brazilian sculptor Antonio Francisco Lisboa, better known as Aleijadinho. The project made use of advanced acquisition and processing of 3D meshes for preservation and dissemination of the cultural herita...
