    Bord Gis required a deeper insight into the dynamics of Uplift prices. The aim of the group was to apply a variety of analytical tools to the problem in order to satisfy Bord Gis requirements. The group conducted a KKT Optimality Analysis of the quadratic program used to determine the Uplift prices, performed statistical analysis to identify the binding constraints and their sensitives to the Uplift prices, simulated a synthetic stochastic process that is consistent with the Uplift pricing series and investigated alternative objective functions for the quadratic program

    La representación de los procesos de construcción de la identidad en los contextos interculturales de dos películas mexicanas sobre la Conquista

    Some of the foundational myths about Mexican identity are revised ¿a this article by focusing on two contemporary films dealing with «La Conquista», Cabeza de Vaca (1990) and Bartolomé de Las Casas (1992). Both films depart from the former Latin-American tradition of condemnation of the official historical construct creared around rite Spanish colonization in America. The individual figures of the homonymous protagonists become the link between the colonial and colonized cultures by favouring dialogue and the engagement with the «other» culture. However their inability to transcend the binary opposition civilized / underdeveloped culture projects a condescending view of the indigenous culture rather than any positive identification or hybridization. As a consequence, the image of the Mexican colonization emanating from these films remains unsatisfactory, since the given positions of authority ciad subaltern are not fully questioned or subverted within the films’ dynamics

    In silico discovery of novel transcription factors regulated by mTOR-pathway activities

    The mammalian target of rapamycine (mTOR) pathway is a key regulator of cellular growth, development and ageing, and unraveling its control is essential for understanding life and death of biological organisms. A motif-discovery workbench including nine tools was used to identify transcription factors involved in five basic (Insulin, MAPK, VEGF, Hypoxia, and mTOR core) activities of the mTOR pathway. Discovered transcription factors are classified as process-specific or pathway-ubiquitous with highlights towards their regulating/regulated activities within the mTOR pathway. Our transcription regulation results will facilitate further research on investigating the control mechanism in mTOR pathway

    Superficial and deep-seated gravity-driven deformation horizons within basinal succession: the case study of Maiolica Formation, Gargano Promontory, Southern Italy

    Gravitational phenomena on the paleoslope of continental margins play a significant role both in redistribution of sediment and formation of new structural features within sedimentary basins worldwide. Mass-transport deposits (MTDs) represent important heterogeneities within the succession and occur on various scales (tens of centimetres to hundreds of metres). Small- to medium-scale MTDs (up to tens of meters) act as layers of different petrophysical properties, whereas large-scale MTDs (tens to hundreds of meters) form both stratigraphic and structural discontinuities (faults, thrusts, erosional surfaces, dykes or injections) within the succession. The Maiolica Formation, Early Cretaceous deep basinal succession cropping out in Gargano Promontory of Southeast Italy is represented by undisturbed intervals of flat-lying thin-bedded, cherty micritic limestone interstratified with intervals of lithologically similar, but structurally distorted beds. For this reason, the studied outcrops provide a good opportunity to characterize the geometry and the internal deformation of small- and medium-scale carbonate MTDs. At the outcrop scale, small- to medium-sized MTDs can be simply identified as sheets of deformed strata alternated with packages of undeformed beds. However, several observed features such as folded stylolites with radially oriented peaks within some of these deformed packages and the presence of large vertical clastic-dyke-like bodies in the succession suggest that some of these deformed packages represent deep-seated basal gliding horizons of large-scale MTDs. In this study, we present MTDs on two different scales that have a crucial influence on the evolution of slope to basinal successions. Moreover, we define the features that distinguish superficial MTDs from the deep-seated gravity-driven deformation horizons within basinal carbonates
