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
Dodging rapidly approaching objects is a fundamental skill for both animals and intelligent robots. Flies are adept at high-speed collision avoidance. However, it remains unclear whether the fly algorithm can be extracted and is applicable to real-time machine vision. In this study, we developed a computational model inspired by the looming detection circuit recently identified in Drosophila. Our results suggest that in the face of considerably noisy local motion signals, the key for the fly circuit to achieve accurate detection is attributed to two computation strategies: population encoding and nonlinear integration. The model is further shown to be an effective algorithm for collision avoidance by virtual robot tests. The algorithm is characterized by practical flexibility, whose looming detection parameters can be modulated depending on factors such as the body size of the robots. The model sheds light on the potential of the concise fly algorithm in real-time applications.
