Mating system evolution and self-incompatibility in the wild plant species Brassica cretica

Compared to animals like ourselves, plants have a very flexible sexual life. Most plants are, for example, hermaphrodites with the potential capacity for reproduction by self-fertilization (or selfing). While selfing can provide several definite advantages for the individual plant, there is a downside; mainly the severe reduction in fitness due to inbreeding depression. To avoid the negative conse

Measurement of the correlation between the polar angles of leptons from top quark decays in the helicity basis at root s=7 TeV using the ATLAS detector

A measurement of the correlations between the polar angles of leptons from the decay of pair-produced t and (t) over bar quarks in the helicity basis is reported, using proton-proton collision data collected by the ATLAS detector at the LHC. The dataset corresponds to an integrated luminosity of 4.6 fb(-1) at a center-of-mass energy of root s = 7 TeV collected during 2011. Candidate events are sel

Search for a Heavy Neutral Particle Decaying to e mu, e tau, or mu tau in pp Collisions at root s=8 TeV with the ATLAS Detector

This Letter presents a search for a heavy neutral particle decaying into an opposite-sign different-flavor dilepton pair, e(+/-) mu(-/+), e(+/-) tau(-/+), or mu(+/-) tau(-/+) using 20.3 fb(-1) of pp collision data at root s = 8 TeV collected by the ATLAS detector at the LHC. The numbers of observed candidate events are compatible with the standard model expectations. Limits are set on the cross se

Pleckstrin homology domains of Tec family protein kinases

Pleckstrin homology (PH) domains have been shown to be involved in different interactions, including binding to inositol compounds, protein kinase C isoforms, and heterotrimer ic G proteins. In some cases, the most important function of PH domains is: transient localisation of proteins to membranes, where they can interact with their partners. Tec family protein tyrosine kinases contain a PH domai

THE PRONOMINALISATION OF CULTURE. DYADIC AND TRIADIC MODELS OF INTERCULTURALITY

A sense can be given, in qualitative rather than quantitative terms, to the three-part distinction, within the semiotics of culture, of Culture, Non-culture, and Extra-culture, by having recourse to the analysis of pronouns into two binary correlations, personality and subjectivity, originally proposed by Benveniste. The present communication will address two related themes: the possible relations
