Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Conference Paper Description
The ALPIDE silicon pixel detector, designed for the upgrade of the ALICE Inner Tracking System at the CERN LHC, is potentially well suited also for usage in other fields, as for medical applications. In particular, it could provide excellent capabilities as detecting probe for radioguided surgery in oncology, in association to positron-emitting radiotracers. In this respect, to quantify the expected performance it is crucial to measure the sensitivity to low-energy photons, which constitute the main background for revealing the positron radiation. Due to its thin epitaxial sensitive layer, the ALPIDE is expected to be almost insensitive to photons. A measurement of the ALPIDE efficiency for the detection of 662 keV photons, emitted by a Cs-137 radioactive source, is reported in this paper. A value of 0.089%, with a relative uncertainty of 20%, was obtained, granting an excellent rejection of low-energy photons compared to other proposed devices.
