Vor diesem Hin...

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...

All known life requires phosphorus (P) in the form of inorganic phosphate (PO4 3x or Pi) and phosphate-containing organic molecules. Pi serves as the backbone of the nucleic acids that constitute genetic material and as the major repository of chemical energy for metabolism in polyphosphate bonds. Arsenic (As) lies directly below P on the periodic table and so the two elements share many chemic...
