A proposito dell\u2019inchiesta della S. Congregazione dell\u2019Indice dei libri proibiti di fine \u2018500
Il paper \u2013 diviso in tre parti \u2013 muove dai risultati della \u201cRicerca sull\u2019inchiesta della Congregazione dell\u2019Indice\u201d che ha preso in esame i codici Vaticani Latini che conservano circa 9500 liste di titoli di libri posseduti dai religiosi italiani alla fine del XVI secolo. Roberto Rusconi sviluppa una panoramica introduttiva sulle biblioteche degli ordini religiosi alla fi ne del Cinquecento. Giovanna Granata sfrutta le molteplici potenzialit\ue0 informative
dell\u2019Inchiesta, sia in termini di conoscenza di tali biblioteche, sia rispetto alle modalit\ue0 di circolazione delle diverse edizioni. Rosa Marisa Borraccini prende invece in esame un caso di
studio come quello del 'Confessionario' di Girolamo da Palermo per dimostrare l\u2019importanza che un testo oggi quasi del tutto sconosciuto aveva all\u2019epoca della sua produzione.
This paper \u2013 divided into three sections \u2013 expands upon the work undertaken in \u201cRicerca sull\u2019inchiesta della Congregazione dell\u2019Indice\u201d, which has examined the Codici Vaticani Latini, a collection which conserves around 9.500 lists of volumes owned by Italian monks and clerics at the end of the sixteenth century. Roberto Rusconi offers an introductory overview of the libraries of religious orders at the end of the sixteenth century. Giovanna Granata analyses the findings of the Inchiesta in terms of actual library holdings and in terms of the circulation of different editions. Rosa Marisa Borraccini examines the case study of the \u201cConfessionario\u201d of Girolamo da Palermo to demonstrate the importance certain texts, although now forgotten and largely ignored, had at the time of their production and circulation
TASTE IV. Refining ephemeris and orbital parameters for HAT-P-20b and WASP-1b
We present four new light curves of transiting exoplanets WASP-1b and
HAT-P-20b, observed within the TASTE (The Asiago Search for Transit timing
variations of Exoplanets) project. We re-analyzed light curves from the
literature in a homogeneous way, calculating a refined ephemeris and
orbital-physical parameters for both objects. WASP-1b does not show any
significant Transit Timing Variation signal at the 120 s-level. As for
HAT-P-20b, we detected a deviation from our re-estimated linear ephemeris that
could be ascribed to the presence of a perturber or, more probably, to a
previously unnoticed high level of stellar activity. The rotational period of
HAT-P-20 A we obtained from archival data (P_rot ~ 14.5 days), combined with
its optical variability and strong emission of CaII H&K lines, is consistent
with a young stellar age (< 1 Gyr) and support the hypothesis that stellar
activity may be responsible of the measured deviations of the transit times.Comment: 7 pages, 4 figures, 3 tables, accepted to Astronomische Nachrichte
Variable stars in one open cluster within the Kepler/K2-Campaign-5 field: M 67 (NGC 2682)
In this paper we continue the release of high-level data products from the
multiyear photometric survey collected at the 67/92 cm Schmidt Telescope in
Asiago. The primary goal of the survey is to discover and to characterise
variable objects and exoplanetary transits in four fields containing five
nearby open clusters spanning a broad range of ages. This second paper releases
a photometric catalogue, in five photometric bands, of the Solar-age,
Solar-metallicity open cluster M 67 (NGC 2682). Proper motions are derived
comparing the positions observed in 2013 at the Asiago's Schmidt Telescope with
those extracted from [email protected] MPG/ESO images in 2000. We also analyse the
variable sources within M 67. We detected 68 variables, 43 of which are new
detection. Variable periods and proper-motion memberships of a large majority
of sources in our catalogue are improved with respect to previous releases. The
entire catalogue will be available in electronic format. Besides the general
interest on an improved catalogue, this work will be particularly useful
because of: (1) the imminent release of Kepler/K2 Campaign-5 data of this
cluster, for which our catalogue will provide an excellent, high spatial
resolution input list, and (2) characterisation of the M 67 stars which are
targets of intense HARPS and HARPS-N radial-velocity surveys for planet search.Comment: 8 pages, 6 figures (2 at low resolution), 2 tables. Accepted for

the overall pulse model for water demand of aggregated residential users
Abstract The models for the end-user demand give a detailed description of the water request, which takes into account the consumes of each dwelling. Therefore, these approaches can model the water demand at WDS nodes by aggregating the single request of each user. The effectiveness of a novel approach the Overall Pulse model (OP)- to describe the aggregated water demand has been tested. In fact, the OP model, unlike the commonly used rectangular pulse models (e.g. PRP, NSRP), does not aim to reconstruct single demand pulses as they occur when home faucets and hydro-sanitary appliances are operated, but allows the generation of the water demand as it is observed at the house water meter. This feature makes the model very versatile, allowing the direct modeling of either a single user or of a group of n users. The possibility of 'pre-aggregation' of the water demand makes it easier to take into account the spatial variability of the model parameters. In the paper, the performance of the OP model is investigated, and to this aim the generated time series are compared with the observed ones of real users. In addition, the comparison of series obtained by means of the classical PRP approach and of the OP model show the effectiveness of the latter

Topology-Induced Critical Current Enhancement in Josephson Networks
We investigate the properties of Josephson junction networks with
inhomogeneous architecture. The networks are shaped as "quare comb" planar
lattices on which Josephson junctions link superconducting islands arranged in
the plane to generate the pertinent topology. Compared to the behavior of
reference linear arrays, the temperature dependencies of the Josephson currents
of the branches of the network exhibit relevant differences. The observed
phenomena evidence new and surprising behavior of superconducting Josephson
arrays as well as remarkable similarities with bosonic junction arrays.Comment: improved figures (added magnetic pattern and single junction
