SYNOPSIS Micrococcaceae isolated from the shunt, ventricles, and bloodstream of children with colonized ventriculo-venous shunts were classified within the scheme of Baird-Parker (1963). With one exception, all belonged to subgroup II of the genus Staphylococcus; tests were therefore devised for division within this subgroup, and results are reported in 30 cases from this and other hospitals. S...

Traditional plant breeding is often limited by the genetic diversity within a species. The use of biotechnology allows introducing into a plant, specific traits that come from the same or another plant species. In this paper, we focus on tissue culture of sunflower (Helianthus annuus L., Asteraceae), particularly related to rooting transgenic sunflower plantlets. Sunflower is notoriously recalc...

This paper revisits related randomness attacks against public key encryption schemes as introduced by Paterson, Schuldt and Sibborn (PKC 2014). We present a general transform achieving security for public key encryption in the related randomness setting using as input any secure public key encryption scheme in combination with an auxiliaryinput reconstructive extractor. Specifically, we achieve...

Nominal unification is proven to be quadratic in time and space. It was so by two different approaches, both inspired by the Paterson-Wegman linear unification algorithm, but dramatically different in the way nominal and first-order constraints are dealt with. To handle nominal constraints, Levy and Villaret introduced the notion of replacing while Calvès and Fernández use permutations and sets...

Due to network effects and switching costs in platform markets, entrants generally must offer revolutionary functionality. We explore a second entry path that does not rely upon Schumpeterian innovation: platform envelopment. Through envelopment, a provider in one platform market can enter another platform market, combining its own functionality with the target’s in a multi-platform bundle that...

The two theories for magnetic reconnection, one of Sweet and Parker, and the other of Petschek, are reconciled by exhibiting an extra condition in that of Petschek which reduces his theory to that of Sweet and Parker, provided that the resistivity is constant in space. On the other hand, if the resistivity is enhanced by instabilities, then the reconnection rate of both theories is increased su...
