Characterization of FBK small-pitch 3D diodes after neutron irradiation up to 3.5 × 1016 neq cm−2
No full textWe report on the characterization by a position resolved laser system of small-pitch 3D diodes irradiated with neutrons up to an extremely high fluence of 3.5 x 10(16) n(eq) cm(-2). We show that very high values of signal efficiency are obtained, in good agreement with the geometrical expectation based on the small values of the inter-electrode spacings, and also boosted by charge multiplication effects at high voltage. These results confirm the very high radiation tolerance of small-pitch 3D sensors well beyond the maximum fluences expected at the High Luminosity LHC
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
I granati delle Fosse di Novale (VICENZA)
No full textRecent soils derived from erosion and alteration of Eocene rocks of the Veneto Volcanic Province (NE Italy) contain detrital
millimetric garnets together with many other magmatic and metamorphic minerals, such as zircon, topaz, corundum, beryl, ilmenite and clinopyroxene. EMPA analyses on pink to dark red grains revealed two compositional types, namely almandine-rich (pink) and pyrope-rich (dark red) garnets, respectively. LA-ICP-MS data indicated that the analysed garnets are LREE-depleted, whereas heavy rare earth element (HREE) concentrations are variably enriched, according to the different colour of garnets. This means that, in terms of major elements and trace element patterns, Py-rich garnets are similar in composition to those of typical garnets from mantle-derived rocks (e.g., garnet peridotite/pyroxenite or eclogite). Alm-rich garnets are closer in composition to those of metamorphic rocks (e.g., gneisses and schists). Py-rich garnets could be transported from mantle depths to the surface by Tertiary mantle-derived alkaline basalts of the Veneto Volcanic Province, also carrying zircon megacrysts and spinel peridotite xenoliths. The source of Alm-rich garnets may be found in the crust crossed by the same magmas

Silicon pin detector with integrated JFET-based source follower
No full textA pin photodiode monolithically integrated with a bias resistor and a JFET-based source follower is presented. Results from static and dynamic characterisation of the structure are reported, together with SPICE simulations used to design an optimised device which can be fabricated in the same technology. This structure can be employed as a pixel in linear X-ray scanners for non-destructive inspection
I noduli di peridotite a spinello nel filone basaltico di Valle di Fondi (Altopiano di Asiago, Vicenza). Microstrutture, composizione e geotermometria.
No full textUltramafic xenoliths found in the mafic dyke of Valle di Fondi (Sette Comuni Plateau, NE Italy) show textural and compositional features similar to those of well-known mantle xenoliths reported for Tertiary volcanics of the Lessini Hills. The equilibration temperatures reached by minerals (Tmean=985+/-73°C) indicate that these xenoliths re-equilibrated before their incorporation by the host magma. the maximum pressure at which the xenoliths could stabilize are indicated by the composition of spinel, and vary between 1.69 and 1.77 GPa, corresponding to about 50 km in depth. Mafic magma, which originated at deeper depths, therefore pulled away fragments of upper mantle during its rapid ascent to the surface

Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
