The deployment of Self-Organizing Networks (SONs) raises a number of key design issues such as scalability, spontaneity, ease-of-management, adaptability, and dynamicallychanging topologies. In this context, routing is particularly challenging, and requires revisiting important components of the routing architecture/protocol suite, such as, establishing and managing an addressing scheme, provid...

We present Timbuk a tree automata library which implements usual operations on tree automata as well as a completion algorithm used to compute an over-approximation of the set of descendants R (E) for a regular set E and a term rewriting system R, possibly non linear and non terminating. On several examples of term rewriting systems representing programs and systems to verify, we show how to us...

barrier to the permeation of most drugs, and especially as a hydrophobic barrier against hydrophilic drugs and ionized drugs. One possible means of facilitating the transdermal delivery of ionic drugs is through ion-pair formation. Oppositely charged ions can interact to form new species known as ion-pairs. This association reduces or neutralizes electrostatic charges and consequently reduces t...

been proven to be a rich source of new biologically active secondary metabolites. In our search for new natural products from marine-derived organisms, here we report the isolation and structure elucidation of a new antimicrobial anthraquinone, monodictyquinone A (1), along with three known compounds, pachybasin (2), chrysophanol (3), and emodin (4). The marine-derived fungus Monodictys sp. was...
