A new polyacetylene glucoside (3E,5E,11E)-tridecatriene-7,9-diyne-1,2,13-triol-2-O-β-D-glucopyranoside (1), a new phenylpropanoid glucoside 2'-butoxyethylconiferin (2), and a new flavonoid glycoside 8,3',4'-trihydroxyflavone-7-O-(6''-O-p-coumaroyl)-β-D-glucopyranoside (3), have been isolated from Bidens frondosa together with fifty-three known compounds 4-56. The structures of these compounds w...

The Positive and Negative Affect Scale for Children (PANAS-C) and the Physiological Hyperarousal Scale for Children (PH-C) were administered to a group of 240 children from European countries to determine their utility in examining the tripartite model of anxiety and depression in a cross-cultural sample. Most of the children (n = 196) had been diagnosed with a medical illness; the remainder we...

Pseudopalicus bidens (Brachyura, Palicidae) is described as a new species from the Andaman Sea, on the western coast of Thailand. The new species can be distinguished from its congeners by its anterolateral teeth on each side of the carapace, with the first two being considerably larger than the last two, as well as for morphology of the gonopods. The new species will bring the number of descri...

A triangle in a triple system is a collection of three edges isomorphic to {123, 124, 345}. A triple system is triangle-free if it contains no three edges forming a triangle. It is tripartite if it has a vertex partition into three parts such that every edge has exactly one point in each part. It is easy to see that every tripartite triple system is triangle-free. We prove that almost all trian...

Joux’s protocol [29] is a one round, tripartite key agreement protocol that is more bandwidth-efficient than any previous three-party key agreement protocol. But it is insecure, suffering from a simple man-inthe-middle attack. This paper shows how to make Joux’s protocol secure, presenting several tripartite, authenticated key agreement protocols that still require only one round of communicati...

The DNA three-way junction serves as a scaffold for the molecular organization of non-nucleosidic alkynylpyrene and perylenediimide chromophores located at the branch point of the structure. Depending on the composition of the tripartite assembly, the constructs possess distinct spectroscopic properties, ranging from monomer or excimer fluorescence to completely quenched tripartite aggregates.
