From fuzzy to annotated semantic web languages

The aim of this chapter is to present a detailed, selfcontained and comprehensive account of the state of the art in representing and reasoning with fuzzy knowledge in Semantic Web Languages such as triple languages RDF/RDFS, conceptual languages of the OWL 2 family and rule languages. We further show how one may generalise them to so-called annotation domains, that cover also e.g. temporal and provenance extensions

Introduction to the special issue on the statistical mechanics of climate

We introduce the special issue on the Statistical Mechanics of Climate by presenting an informal discussion of some theoretical aspects of climate dynamics that make it a topic of great interest for mathematicians and theoretical physicists. In particular, we briefly discuss its nonequilibrium and multiscale properties, the relationship between natural climate variability and climate change, the different regimes of climate response to perturbations, and critical transitions

Aloysia citriodora Palau

Aloysia citriodora Palau, cedron or lemon verbena, is a South American aromatic species widespread in North America, Eurasia, and Africa. It is appreciated because it therapeutic and food (condiment, flavoring) uses. Also is valued as ornamental, insect repellent, and sometimes in perfumery. Its popular culinary and medicinal uses have been expanded from Latin America to the rest of the Western world. Its main active constituents are essential oils, to which owes its aroma and flavor similar to lemon, but also contain flavonoids, verbascosides, iridoids heterosides, and others. It most disseminated uses in folk medicine include those to treat gastrointestinal disorders (digestive, antispasmodic, carminative, antidiarrheal), mild sedative, cardiotonic, febrifuge, analgesic, and antiseptic. Various experimental studies validate different effects, as eupeptic, spasmolytic, antimicrobial, anti-inflammatory, analgesic, hypotensive, among others. Its sedative/anxiolytic activity requires deeper further studies. Of particular interest are its cancer-related effects analyzed to date (antimutagenic, antigenotoxic, and antiangiogenic), and its antioxidant activity linked in various ways to our health.Fil: Hurrell, Julio Alberto.
