In silico and in vitro comparative analysis to select, validate and test SNPs for human identification.

2007

Abstract Background The recent advances in human genetics have recently provided new insights into phenotypic variation and genome variability. Current forensic DNA techniques involve the search for genetic similarities and differences between biological samples. Consequently the selection of ideal genomic biomarkers for human identification is crucial in order to ensure the highest stability and reproducibility of results. Results In the present study, we selected and validated 24 SNPs which are useful in human identification in 1,040 unrelated samples originating from three different populations (Italian, Benin Gulf and Mongolian). A Rigorous in silico selection of these markers provided …

The Role of Recent Admixture in Forming the Contemporary West Eurasian Genomic Landscape

2015

Summary Over the past few years, studies of DNA isolated from human fossils and archaeological remains have generated considerable novel insight into the history of our species. Several landmark papers have described the genomes of ancient humans across West Eurasia, demonstrating the presence of large-scale, dynamic population movements over the last 10,000 years, such that ancestry across present-day populations is likely to be a mixture of several ancient groups [1, 2, 3, 4, 5, 6, 7]. While these efforts are bringing the details of West Eurasian prehistory into increasing focus, studies aimed at understanding the processes behind the generation of the current West Eurasian genetic landsc…

Otra política d asilo es posible en Europea. Una breve comparación entre la UE y Canadá.

2016

La situación que ha generado en la Unión Europea la mal denominada “crisis de los refugiados”, pone en evidencia hasta qué punto ha fracasado el denominado Sistema Común de Asilo. Múltiples factores han concurrido, durante dos décadas, hasta llegar a lo que puede considerarse una desnaturalización del asilo. Para reivindicar la necesidad de protección internacional como un derecho en el contexto europeo, es interesante analizar, como propone este trabajo, los múltiples factores que han concurrido para que el sistema Dublín no llegue a implementarse. Dicho estudio, además, puede completarse desde una perspectiva comparada atendiendo al caso canadiense. La confrontación entre algunas de las m…

Late Cretaceous echinoderm ‘odds and ends’ from the Low Countries

2018

From various levels within the Gulpen and Maastricht formations (upper lower to upper upper Maastrichtian, c. 69.5–66 Ma) in the extended type area of the Maastrichtian Stage (southeast Netherlands, northeast Belgium and the Aachen area in Germany), a few recent additions to echinoderm faunas are illustrated and briefly discussed. Added are some erratic, flint-preserved, pre-Maastrichtian echinoid taxa from Pleistocene fluvial gravel deposits; these are of palaeogeographical interest. Crinoids include the comatulid Semiometra saskiae with traces of sublethal predation and several bourgueticrinines. Amongst the latter, the species Dunnicrinus aequalis is found preserved in biocalcarenites as…

Efficient generation of energetic ions in multi-ion plasmas by radio-frequency heating

2017

We describe a new technique for the efficient generation of high-energy ions with electromagnetic ion cyclotron waves in multi-ion plasmas. The discussed ‘three-ion’ scenarios are especially suited for strong wave absorption by a very low number of resonant ions. To observe this effect, the plasma composition has to be properly adjusted, as prescribed by theory. We demonstrate the potential of the method on the world-largest plasma magnetic confinement device, JET (Joint European Torus, Culham, UK), and the high-magnetic-field tokamak Alcator C-Mod (Cambridge, USA). The obtained results demonstrate efficient acceleration of 3He ions to high energies in dedicated hydrogen–deuterium mixtures.…

Long-term changes in drought indices in eastern and central Europe

2021

This study analyses long-term changes in drought indices (Standardised Precipitation Index—SPI, Standardised Precipitation–Evapotranspiration Index—SPEI) at 1 and 3?months scales at 182 stations in 11 central and eastern European countries during 1949–2018. For comparative purposes, the necessary atmospheric evaporative demand (AED) to obtain SPEI was calculated using two methods, Hargreaves-Samani (SPEIH) and Penman-Monteith (SPEIP). The results show some relevant changes and tendencies in the drought indices. Statistically significant increase in SPI and SPEI during the cold season (November–March), reflecting precipitation increase, was found in the northern part of the study region, in …
