Status of the Phase-2 Tracker Upgrade of the CMS experiment at the HL-LHC
No full textThe Phase-2 Upgrade of the CMS experiment is designed to prepare its detectors for operations at the High Luminosity Large Hadron Collider (HL-LHC). The upgraded collider, scheduled to start operations in 2027, will lead to challenging conditions in terms of data throughput, pile-up and radiation. For these reasons the tracker detector will be entirely replaced by a new detector, the Phase-2 tracker. We present the status of the design, test and validation of the components of the Phase-2 tracker, and its read-out, calibration, control, and data processing chains \footnote{Published in "Journal of Physics: Conference Series" as "Luigi Calligaris and on behalf of the CMS collaboration 2020 J.

Appropriate laboratory utilization in diagnosing pulmonary embolism
No full textBackground: The appropriateness of clinical laboratory use in hospital clinical practice is a very debated question. In fact diagnostic tests are essential tools for disease screening or diagnosis but at the same time they represent an important expenditure.
Methods: A quantitative study was conducted in an Italian general hospital with 535 beds and about 27,000 admissions per year. The sample was made of all patients discharged from the hospital with DRG 78 between the period 1 January 2005 and 31 December 2005.
Results: The Emergency Department (ED) discharged 2.9% (116/4009) of patients with pulmonary embolism diagnosis in the year 2005. The percentage of prescription inappropriateness inferred by analysis of all required tests by operative unit was 21.7% (950/4385). The approximate estimate of the economic value of unnecessarily required tests was of 3495(sic). Of these 96.5% (112/116) had enlisting criteria. All haematological and clinical-chemical tests (11295) concerning studied patients were analysed. About 70.4% (93/132) of d-dimer tests were ordered in ED. In the studied patients, unfractionated heparin was administered in 17.8% (20/112) of the cases, low-molecular weight heparin in 79.5% (89/112) and heparin therapy was not administered in 2.7% (three of 112).
Conclusion: This study uses a method to assess the quality of laboratory test orders using results as a tool to estimate the impact of economic resources devolved in executing inappropriate tests
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
