The video referee: politics, football and bodies in (moving) images

A utilização oficial do árbitro de vídeo (VAR) na Copa do mundo de futebol da Rússia 2018 nos faz interpelar algumas questões que nos parecem carecer de arguição. Este ensaio insere-se na polêmica da adoção do VAR no futebol partindo de suas questões corriqueiras com o objetivo de adensar os tipos de questões ontológicas e axiológicas que são demandadas ao futebol frente ao uso desta tecnologia, bem como os desdobramentos das ações tecnológicas sobre o corpo de quem joga, arbitra e assiste, ações estas de intervenção política e estética. Podemos concluir que as justificativas e anseios pela justiça na condução do jogo que alimentam a adoção do VAR tão somente geram novas expectativas e novas demandas tecnológicas. Tal burocratização vai perdendo a dimensão humana imprevisível e passível de erro que caracteriza as práticas esportivas.The official use of the video referee (VAR) in the 2018 Russia World Cup allows to question some characteristics that seem not to have been argued. This essay is inserted in the controversial adoption of the VAR in football, condensing some ontological and axiological considerations that are demanded in football against the use of technology, as well as the articulations of technological actions on the body of who competes, arbitrates and attends, actions that are both aesthetic and political intervention. It is concluded that the justifications and desires of justice during the games only generate new expectations and new technological demands, beyond the official implementation of VAR. Such bureaucratization loses some human dimension of the unpredictable and liable to error that characterizes sports practices.Facultad de Humanidades y Ciencias de la Educación (FAHCE

Ancient DNA re-opens the question of the phylogenetic position of the Sardinian pika Prolagus sardus (Wagner, 1829), an extinct lagomorph

Palaeogenomics is contributing to refine our understanding of many major evolutionary events at an unprecedented resolution, with relevant impacts in several fields, including phylogenetics of extinct species. Few extant and extinct animal species from Mediterranean regions have been characterised at the DNA level thus far. The Sardinian pika, Prolagus sardus (Wagner, 1829), was an iconic lagomorph species that populated Sardinia and Corsica and became extinct during the Holocene. There is a certain scientific debate on the phylogenetic assignment of the extinct genus Prolagus to the family Ochotonidae (one of the only two extant families of the order Lagomorpha) or to a separated family Prolagidae, or to the subfamily Prolaginae within the family Ochotonidae. In this study, we successfully reconstructed a portion of the mitogenome of a Sardinian pika dated to the Neolithic period and recovered from the Cabaddaris cave, an archaeological site in Sardinia. Our calibrated phylogeny may support the hypothesis that the genus Prolagus is an independent sister group to the family Ochotonidae that diverged from the Ochotona genus lineage about 30 million years ago. These results may contribute to refine the phylogenetic interpretation of the morphological peculiarities of the Prolagus genus already described by palaeontological studies

Preliminary results of 3D-DDTC pixel detectors for the ATLAS upgrade

3D Silicon sensors fabricated at FBK-irst with the Double-side Double Type Column (DDTC) approach and columnar electrodes only partially etched through p-type substrates were tested in laboratory and in a 1.35 Tesla magnetic field with a 180GeV pion beam at CERN SPS. The substrate thickness of the sensors is about 200um, and different column depths are available, with overlaps between junction columns (etched from the front side) and ohmic columns (etched from the back side) in the range from 110um to 150um. The devices under test were bump bonded to the ATLAS Pixel readout chip (FEI3) at SELEX SI (Rome, Italy). We report leakage current and noise measurements, results of functional tests with Am241 gamma-ray sources, charge collection tests with Sr90 beta-source and an overview of preliminary results from the CERN beam test.Comment: 8 pages, 8 figures, presented at RD09 - 9th International Conference on Large Scale Applications and Radiation Hardness of Semiconductor Detectors, 30 September - 2 October 2009, Florence, Ital

Development of 3D detectors at FBK-irst

We report on the development of 3D detectors at Fondazione Bruno Kessler - irst in the framework of the CERN RD-50 Collaboration. Technological and design aspects dealing with the 3D Single Type Column detectors are reviewed, and selected results from the electrical and functional characterization of prototypes are reported and discussed. A new detector concept, namely 3D Double-side Double Type Column detectors, allowing for significant performance enhancement while maintaining a reasonable process complexity, is final ly addressed

DTT - Divertor Tokamak Test facility: A testbed for DEMO

The effective treatment of the heat and power exhaust is a critical issue in the road map to the realization of the fusion energy. In order to provide possible, reliable, well assessed and on-time answers to DEMO, the Divertor Tokamak Test facility (DTT) has been conceived and projected to be carried out and operated within the European strategy in fusion technology. This paper, based on the invited plenary talk at the 31st virtual SOFT Conference 2020, provides an overview of the DTT scientific proposal, which is deeply illustrated in the 2019 DTT Interim Design Report
