"Set Inference in Latent Variables Models"

We propose a methodology for constructing valid confidence regions in incomplete models with latent variables satisfying moment equality restrictions. These include moment equality and inequality models with latent variables. The confidence regions are obtained by inverting tests based on the characterization of the identified set derived in Ekeland, Galichon, and Henry (2010). A valid boot- strap approximation of the distribution of the test statistic is derived under mild conditions and the confidence regions are shown to have correct asymptotic size.

Two new species of Cyperus (Cyperaceae) from the Zambezian region of Africa

Cyperus absconditicoronatus Banters, Reynders & Goetgh. and C. unispicatus Banters, Reynders & Goetgh., two new species of Cyperus L. (Cyperaceae) from Angola and Zambia, are recognized. Cyperus absconditicoronatus is a tall species (55-100 cm) characterized by a scaled rhizome, a single terminal capitulum, a ciliated spikelet bract, and deciduous spikelets. Cyperus unispicatus can be recognized by a swollen and fibrous stem base growing from slender rhizomes, a single terminal spike, and short involucral bracts. The taxa are described and illustrated, and differences with the closest resembling species are discussed

Les divinites feminines de la fertilite et de la fecondite en Hispania pendant l'epoque romaine

Nous nous trouvons devant un des aspects qui comptent peu de temoignages dans l'archeologie hispanique, fait que l'on ne doit pas imputer seulement cl des lacunes d'information. Il y a en effet une absence de documents qui remonte jusqu'a l'epoque prehistorique. Il suffira de rappeler l'absence totale, meme dans la riche zone cantabrique, de "Venus" paleolithiques.' Les premieres sculptures feminines ayant les traits sexuels bien marques, correspondent cl des representations qui datent de la periode Eneolithique et gagnent progressivement en realisme au commencement de l'Age de Bronze; leur localisation coincide avec le midi peninsulaire avec une plus forte concentration dans le Sudouest. Il s'agit d'images d'une divinite feminine de fecondite arrivees par des filtrations du monde mediterraneen parce que, en plus des parallelles anatoliques, il semble bien qu'elle corresponde a la meme divinite semite derivee d'Astarte et veneree plus tard dans le monde autochtone preromain aussi bien dans la zone celtique (Cerro del Berrueco, Salamanque) que dans l'iberique. Les premieres sculptures feminines de fecondite arrivent, donc, par des contacts mediterraneens.peer-reviewe

An innovative integrated approach based on DNA walking to identify unauthorized GMOs

&lt;p&gt;In the next coming years, the frequency of unauthorized genetically modified organisms (GMOs) being present in the European food/feed chain will increase significantly. Rice already constitutes a challenge for laboratories developing methods to detect unauthorized GMOs. Indeed, in 2012, several genetic modified rices were detected in products imported from Asia, mainly from China. Therefore, we have developed a strategy to identify unauthorized GMOs containing a pCAMBIA family vector, frequently present in transgenic plants. The presented integrated approach is performed in two main successive steps on Bt rice grains. First, the potential presence of unauthorized GMOs is assessed by the qPCR SYBR&amp;reg;Green technology targeting the terminator 35S (t35S) pCAMBIA element, which allows discriminating pCAMBIA family vectors. Second, its presence is confirmed via the characterization of the junction between the transgenic cassette and the rice genome. To this end, a DNA walking strategy is applied using a first reverse primer followed by two semi-nested PCR rounds using primers that are each time nested to the previous reverse primer. The sensitivity of the method was assessed. This innovative approach allows to rapidly identifying the transgene flanking region and presents the advantage to be easily implementable in GMO routine analysis by the enforcement laboratories.&lt;/p&gt;</p
