We derive necessary conditions on a Lie algebra from the existence of a star product on a neighbourhood of the origin in the dual of the Lie algebra for the coadjoint Poisson structure which is both di erential and tangential to all the coadjoint orbits. In particular we show that when the Lie algebra is semisimple there are no di erential and tangential star products on any neighbourhood of th...

CODIT‘14 conference or the International Conference on Control, Decision and Information Technologies has been held in Metz from 3 November to 5 November 2014. It has been the occasion to present 141 contributions selected from about 250 submissions (included the special sessions). This event has attracted participants from 34 countries. This special issue is devoted to CODIT’14 but the submiss...

In PG(2, q2) with q > 2, we determine the possible intersections of a nonclassical Buekenhout–Metz unital U and a conic passing through the point at infinity of U .

The 7th International Conference on Nanomaterials by Severe Plastic Deformation (NanoSPD7) is hosted by the University of Sydney (Australia) following a series of earlier conferences: in Moscow (1999), Vienna (2002), Fukuoka (2005), Goslar (2008), Nanjing (2011) and Metz (2014). This introductory paper reports on several major developments in NanoSPD activities as well as on recent NanoSPD cita...

Gender mainstreaming, as a consequence of the gender concept, means that there is no such a thing as gender-neutral policies. Gender politics cannot be restricted to special domains such as family politics, and the challenge to overcome gender barriers cannot be managed by isolated measures such as establishing women‘s representatives in organizations [Metz-Göckel/Kamphans 2005]. According to t...

Neuroendocrine tumors comprise a spectrum of slow growing neoplasm, characterized by storage and secretion of variable peptides and neuroamines (Massironi et al., 2008). Pancreatic neuroendocrine tumors (PNET) are relatively rare, with an estimated incidence of less than 1 per 1000,000 individuals (Metz and Jensen, 2008). A recent review of surveillance epidemiology and end results (SEER) (1950...
