Underground operation of the ICARUS T600 LAr-TPC: first results
No full textImportant open questions are still present in fundamental Physics and Cosmology, like
the nature of Dark Matter, the matter-antimatter asymmetry and the validity of the Standard Model
of particle interactions. Addressing these questions requires a new generation of massive particle
detectors to explore the subatomic and astrophysical worlds. ICARUS T600 is the first large mass
(760 tons) example of a new generation of detectors able to combine the imaging capabilities
of the old famous “bubble chamber” with the excellent energy measurement of huge electronic
detectors. ICARUS T600 now operates at the Gran Sasso underground laboratory and is used to
study cosmic rays, neutrino oscillations and the proton decay. The potential for doing physics of
this novel telescope is presented through a few examples of neutrino interactions reconstructed with
unprecedented detail. Detector design and early operation are also reported

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
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
