Motivated by Yung and Miller’s suggestion [1997] that N2O is isotopically fractionated during UV photolysis in the stratosphere, we have studied the photolysis rates of the NNO and NNO structural isotopomers. In this study, we follow the concentrations of these compounds with FTIR spectroscopy during photolysis at 213 nm. Our results show that, as Yung and Miller predicted, the photolysis rate ...

In this paper we analyse the security of two authenticated group key agreement schemes based on the group key agreement protocol of Burmester and Desmedt. One scheme was proposed by Burmester and Desmedt, and uses a separate authentication scheme to achieve authentication among the participants. We show that this scheme suffers from a number of security vulnerabilities. The other scheme was gen...

We adapt the Cramer, Franklin, Schoenmaker and Yung internet voting protocol[12] to the booth setting. In this protocol, expressions of the form g 0g x1

Moti Mizrahi has argued that Thomas Kuhn does not have a good argument for the incommensurability of successive scientific paradigms. With Rouse, Andersen, and others, I defend a view on which Kuhn primarily was trying to explain scientific practice in Structure. Kuhn, like Hilary Putnam, incorporated sociological and psychological methods into his history of science. On Kuhn’s account, the edu...

Suppose that λ = μ and μ is singular. We consider two aspects of the square property on subsets of λ. First, we have results which show e.g. that for א0 < κ = cf(κ) < μ, the equality cf([μ],⊆) = μ is a sufficient condition for the set of elements of λ whose cofinality is ≤ κ, to be split into the union of μ sets with squares. Secondly, we introduce a certain weak version of the square property ...

Dimensional Confinement In article number 2105898, Yung-Chang Lin, Kazu Suenaga, and co-workers report the discovery of a new AlCl3 structure in 2D form. Metal chlorides such as CuCl2 intercalated bilayer graphene are found to have polymorphic phases, which not been previously expected bulk. Utilizing dimensional confinement, growth further unexpected materials nanospace between is expected.
