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.

Article Description
The collapse of a condominium in Florida in 2021 shed light the significance of diagnostic inspection and internal tomography for aging concrete structures. This study investigated the feasibility of applying single-side electrical resistance tomography (ERT) as a diagnostic tool. In previous concrete ERT studies, the approach entailed the placement of electrodes encompassing all facets of the subject specimen. However, in the case of structures like tunnels, it is feasible to gauge electric potential solely on a single side. To overcome this limitation, the present study explored various measurement configurations and approaches, allowing tomographic imaging from only a single side of an ERT object. The present study developed analytical solutions and conducted experimental validation on cement mortar samples with simulated cracks. The “farthest measurement” method among other configurations demonstrated higher sensitivity in detecting inclusions at greater depths. Incorporating theoretical sensitivity information improved the image resolution in image reconstructions of ERT.
