Lidio Gasperini: Scritti di epigrafia greca
No full textRaccolta dei contributi sull’epigrafia greca pubblicati da Lidio Gasperini fra il 1965 ed il 2007, con l’aggiunta di alcuni lavori inediti. I documenti studiati provengono nella maggior parte dei casi da Cirene, ma si hanno anche epigrafi rinvenute a Taranto e nell’Italia meridionale, a Creta e nel Libano; il periodo cronologico in cui si collocano va dall’età arcaica alla tarda antichità. Si tratta in gran parte di iscrizioni inedite, di cui il Gasperini diede l’editio princeps, con notevole apparato di fotografie e di fac-simili. Completano il volume la premessa e gli indici, epigrafico e dei nomi propri

Reply to “Comment on ‘Unbiased Estimation of Moment Magnitude from Body‐ and Surface‐Wave Magnitudes’ by R. Das, H. R. Wason, and M. L. Sharma and ‘Comparative Analysis of Regression Methods Used for Seismic Magnitudes Conversions’ by P. Gasperini, B. Lolli, and S. Castellaro” by J. Pujol
No full textWe suspect that most criticisms by Pujol (2017,
hereafter, P17) were originated by a misunderstanding of our
article (Gasperini et al., 2015) that the author himself frankly
admits (“Some of the arguments made in the paper were not
completely clear to the present author” p. 11) and maybe
even by a misunderstanding of the textbook of Fuller
(1987). In the following, we will discuss in general the main
P17 criticisms, whereas detailed answers to all of them are
reported in the Appendix.Published548–5514IT. Banche datiJCR Journa

Development of oral agent in the treatment of multiple sclerosis: how the first available oral therapy, Fingolimod will change therapeutic paradigm approach
No full textClaudio Gasperini,1 Serena Ruggieri21Department of Neurosciences, S Camillo Forlanini Hospital, 2Department of Neurology and Psychiatry, University of Rome “Sapienza,” Rome, ItalyAbstract: Multiple sclerosis (MS) is a chronic inflammatory disorder of the central nervous system, traditionally considered to be an autoimmune, demyelinating disease. Based on this understanding, the initial therapeutic strategies were directed at immune modulation and inflammation control. At present, there are five licensed first-line disease-modifying drugs and two second-line treatments in MS. Currently available MS therapies have shown significant efficacy throughout many trials, but they produce different side-effect profiles in patients. Since they are well known and safe, they require regular and frequent parenteral administration and are associated with limited long-term treatment adherence. Thus, there is an important need for the development of new therapeutic strategies. Several oral compounds are in late-stage development for treating MS. Fingolimod (FTY720; Novartis, Basel, Switzerland) is an oral sphingosine-1-phosphase receptor modulator which has demonstrated superior efficacy compared with placebo and interferon β-1a in Phase III studies and has been approved in the treatment of MS. We summarily review the oral compounds in study, focusing on the recent development, approval and the clinical experience with FTY720.Keywords: multiple sclerosis, oral compounds, fingolimod, fty720, sphingosine 1, phosphate, patient satisfactio
Time and space clustering of Etna volcano earthquakes during the period May 1983-February 1987
No full textParticularly well located earthquakes exist at Etna volcano for the period May 1983-February 1987, since an 18-stations seismic network was in operation. The space-time clustering of the seismic activity is analyzed statistically in this period by using the model of Gasperini and Mulargia (1989), which is based on the influence region. The following clustering features are identified: (1) clustering is mainly originated by swarm-type sequences; (2) two magnitude-dependent best fits are obtained by an influence region of respectively 1.5 to 6 days and 15 to 20 km; (3) no evident space and time relation between clusters and eruptions is apparent. © 1992
Statistical analysis of seismic and eruptive activities at Mt. Etna during 1978-1987
No full textSeismic and eruptive activities that occurred at Etna volcano during the decade 1978-1987 have been analyzed statistically. The seismic activity consists of about 7500 events. This catalog has been found complete above the magnitude threshold 2.8. On the basis of the complete catalog (1458 earthquakes), the clustering features of seismicity have been investigated. The hypothesis of a Simple Poisson process is rejected. Applying a Generalized Poisson process of the Shlien and Toksoz (1970) type, the "E" parameter of cluster size appears to be strongly dependent on the chosen time interval. The application of Gasperini and Mulargia (1989) algorithm for identifying the single earthquake sequences indicates that the whole period is composed of only three sequences. Etnean seismicity appears therefore characterized by a "diffuse" low-magnitude (less than about 3.0) earthquake occurrence. From the volcanological point of view, two time series of eruptions (flank and flank + summit) have been analyzed in order to identify different regimes in both magma output and inter-event time. No change-points are apparent in the magma output series, while both inter-event time series of flank and flank + summit eruptions are characterized by one change-point each. No evident relation between the series of eruptions and the identified earthquake sequences is apparent. © 1990

EMMA (Earthquake Mechanisms of the Mediterranean Area) database contains available literature data with the
goal of making them more usable and available. EMMA is continuously improving by the addition of further
focal mechanisms found in literature. At the present time, EMMA pre-release 3 includes more than 12700 focal
solutions, about twice of previous official release 2.2 (Vannucci and Gasperini, 2004). They cover a time window
from 1905 to 2006. In the new release, many added solutions are in areas not much covered or completely
uncovered in the previous one (e.g. Bulgaria, Germany, Anatolia).
As in the previous versions (Vannucci and Gasperini, 2003 and 2004), we have uniformed the different formats
and notations of the data available from different sources and we have tried to solve misprints, inaccuracies and
inconsistencies that might make the data unusable for other investigations. By an automatic procedure based on
several criteria, we have chosen the “most representative” (best) solution when more than one is available for
the same earthquake. Thanks to this, we have obtained about 6000 best solutions. The end user can use the best
solution obtained with our procedure or he can change criteria.
The database allows to make selections and to export data files suitable to be handled by graphic software and
user generated scripts. In the new version, still MS-ACCESS based, we have added geographic information to
the display of the focal solution, as well as we have integrated the hypocentral and magnitude data found on the
original papers with those reported by regional and local catalogs and bulletins.
In order to make EMMA more accessible, a web version is currently in progress. Through an internet connection
it will be possible data selection and export, without installation and configuration problems found in the past.
EMMA was already used in the past and will be (hopefully) useful in the future to better characterize the tectonic
deformation styles (e.g. by moment tensors sum within given areas or over regular geographical grids) particularly
in areas of the European region where seismicity is moderate and only few CMT solutions are available.
At the moment, we try to compute strain map for Mediterranean area, using EMMA data. In order to represent
any recurrence in space, we identify small areas and apply to each one some spatial analyses. The work is still in
progress, but preliminary results are satisfactory and in accord to previous studies.PublishedWien5.2. TTC - Banche dati di sismologia strumentaleope
