Test beam results of the GE1/1 prototype for a future upgrade of the CMS high- muon system
Gas Electron Multipliers (GEM) are an interesting technology under
consideration for the future upgrade of the forward region of the CMS muon
system, specifically in the endcap region. With a
sufficiently fine segmentation GEMs can provide precision tracking as well as
fast trigger information. The main objective is to contribute to the
improvement of the CMS muon trigger. The construction of large-area GEM
detectors is challenging both from the technological and production aspects. In
view of the CMS upgrade we have designed and built the largest full-size
Triple-GEM muon detector, which is able to meet the stringent requirements
given the hostile environment at the high-luminosity LHC. Measurements were
performed during several test beam campaigns at the CERN SPS in 2010 and 2011.
The main issues under study are efficiency, spatial resolution and timing
performance with different inter-electrode gap configurations and gas mixtures.
In this paper results of the performance of the prototypes at the beam tests
will be discussed

The TDC based integrated trigger system of the NA62 experiment at CERN
The main goal of the NA62 experiment is to measure the branching ratio of the K + \u2192 \u3c0 +\u3bd\u3bd - decay, collecting O(100) events in two years of data taking. Efficient online selection of interesting events and loss-less readout at high rate will be key issues for such experiment. An integrated trigger and data acquisition system has been designed, where the processing of timing information from the subdetectors is a key element. Only the very first trigger stage will be implemented in hardware, in order to reduce the total rate for the software levels on PC farms. Readout uniformity among different subdetectors and scalability were taken into account in the architecture design. \ua92009 IEEE

Detectors for the next generation PET scanners
Next-generation PET scanners are expected to fulfill very high requirements in terms of spatial, energy and timing resolution. Modern scanner performances are inherently limited by the use of standard photomultiplier tubes. The use of Silicon Photomultiplier (SiPM) matrices is proposed for the construction of a small animal PET system with depth of interaction capabilities. Measurements showing that SiPM matrices are highly ideal for PET applications, have been reported. \ua9 Societ\ue0 Italiana di Fisica
Defining research priorities in cystic fibrosis. Can existing knowledge and training in biomedical research affect the choice?
The aim of this report is to assess whether the research issues priorities are perceived differently according to the Stakeholders (SH)'s individual knowledge of research topics and degree of training in biomedical research. Four groups of SH were enrolled in this study: 1. Skilled SH, specifically trained in biomedicine; 2. Unskilled untrained SH who responded to a written questionnaire in 2015; 3. SH who were trained for one year in a course delivered by professionals; 4. Untrained SH who responded to an online questionnaire in 2017. The large ranking order variability observed among groups addresses the question that the choices are markedly influenced by the SH's backgrounds. Such results emphasize the need to consider the education level and the delivery of ad hoc training activities by professionals to broaden the base of SH who may be considered qualified to transfer the Patient Centered Outcome Research principles into practice
