Metric Options: Counts1 Year3 YearSelecting 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
Contagion spread is a common phenomenon observable on a variety of complex networks. The knowledge of key spreaders and contagion dynamics facilitates the design of applications that can either reduce the spread of unwanted contagion or amplify the proliferation of desired ones. Hence, it is essential to identify and rank the influential (key) spreaders in complex networks. Extended neighbourhood coreness (Cnc+) is one such method that uses the k-shell index to identify and rank the influential spreaders. The neighborhood of a node plays a very important role in contagion spread and the combination of local and global topological information of a node can better capture the spreading influence of the nodes. In this paper, a measure, namely, hybrid Cnc+ coreNess (HCN) is proposed that extends Cnc+ by including first and second order neighbourhood of a node (local information) along with the k-shell index. In experiments, HCN is compared with state of the art methods for both real and artificial datasets. The results show that HCN is accurate and better than state of the art methods. Further, least variation in ranking accuracy is observed in experiments of parameter variation for artificial networks. Computational complexity analysis shows that the proposed method achieves high accuracy incurring a small computational penalty.
