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
Utilizing CO 2 jets for rock breaking in energy exploration provides a dual benefit of enhancing recovery rate and facilitating permanent CO 2 sequestration. The novel technology of multi-hole flashing CO 2 jets shows promise in creating high-quality drilling holes, with a better understanding of jet evolution leading to improved breaking efficiency. In this study, the morphologies of multi-hole flashing liquid CO 2 jets were captured using the diffusive back-illuminated method. However, differences in intensity contrast between the main jet and the background, along with light steer effects induced by severe phase transitions, posed challenges in applying uniform thresholds or adjustment parameters for data comparison. To address this issue and ensure the acquisition of high-credibility data, both static and dynamic background-based methods were employed to mitigate contrast level differences between the main jet and the background. The study also analyzed the impact of image processing on jet width sensitivity. The gradient-based method allows for boundary identification based on uniform criteria regardless of contrast levels between the jet and the background, making it suitable for determining the jet width of multi-hole liquid CO 2 flashing jets.
