Ab initio quantum chemical calculations on normal and hypervalent structures of the HC10 3 species have been performed. Four minima were located at the MP2/6-31G(d) level, after many connectivities were investigated. Geometries and frequencies were determined at the QCISD/6-311G(2d, 2p) level. Singl

Gradients of cellular activities are ubiquitous in embryonic development. It is widely believed that the inhomogeneous spatial distribution of a morphogen would be able to set up such gradients. But how then does the morphogen propagate in the first place? Straightforward molecular diffusion is ofte
