Two antibiotics isolated from a culture MA-2465 were identified as aureothin and labilomycin, the chemical structures of which had been reported previously. It was also concluded that mycolutein and pulvomycin isolated as antibiotics in 1955 and 1957 respectively are also identical with aureothin and labilomycin. A cursory study of MA-2465 indicates that it is distinctly different from the cult...

n page 1133, Bao et al. demonstrate that a neuronal growth factor signals to neighboring cells while also communicating back to the nucleus of its own cell. This two-way signaling is necessary to maintain neuronal survival. In the forward direction , either a soluble or membrane-bound form of the Nrg-1 growth factor activates erbB receptor tyrosine kinases on a variety of adjacent cells. The Nr...

For those of us that generally live in the world of syntax, semantic proof techniques such as realizability or logical relations/parametricity sometimes feel like magic. Why do they work? At which point in the proof is “the real work” done? Bernardy and Lasson [4] express realizability and parametricity models as syntactic models – but the abstraction/adequacy theorems are still explained as me...

The main objective of this paper is to add one more brick in building the CG model as a knowledge representation model autonomous from logic. The CG model is not only a graphical representation of logic, it is much more: it is a declarative model encoding knowledge in a mathematical theory, namely labelled graph theory, which has eecient computable forms, with a fundamental graph operation on t...
