The intrinsic volumes of Gaussian polytopes are considered. A lower variance bound for these quantities is proved, showing that, under suitable normalization, the variances converge to strictly positive limits. The implications of this missing piece of the jigsaw in the theory of Gaussian polytopes are discussed. 2010 Mathematics Subject Classification: Primary 60D05; Secondary 52A22.

One of the most important characteristics of virtual and networked organizations is the facilitation of interactions across institutional boundaries. However, the facilitation of this cross-boundary interaction does not mean that these boundaries cease to exist altogether; they may change forms, but still maintain their function and importance, and should be taken into consideration both in the...

The coordinated growth of epidermal cells in plant leaves creates the characteristic jigsaw puzzle appearance of the pavement cells. Now, Xu et al. (2010) report that AUXIN-BINDING PROTEIN 1 mediates auxin activation of two GTPase pathways that antagonistically control planar morphogenesis of leaf epidermal cells to create this distinctive pattern.
