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
Background and Objective: COVID-19 is a new respiratory infectious disease caused by severe acute respiratory syndrome coronavirus type II (SARS-COV-2), which has had a huge impact on the medical system. Because the focus of COVID-19 is in the lungs, doctors are able to determine if a patient has COVID-19 by looking at chest X-rays. This paper uses the advantages of deep learning algorithms for automatic diagnosis and treatment of COVID-19 in lung medical images to automatically detect chest X-ray images. Methods: The multi-channel attention (MLPA) module in the lightweight and multi-channel attention network (MLPA-Net) can extract important features in the complicated image areas, extract the weight of multi-channel, and enrich image feature information. The multilayer perceptron (MLP) in MLPA can randomly assign edge weights and update the weights through backpropagation to obtain more favorable feature information. Results: In the proposed dataset, MLPA-NET achieves 99.1% accuracy and 0.991 F1 score for the two-classification, and 98.4% accuracy and 0.980 F1 score for the three-classification. The effectiveness of the improvements to our method was demonstrated through ablation experiments. Conclusion: MLPA-Net is able to focus on the lesion area of the image, helping doctors to classify efficiently, saving time and improving efficiency. Compared with previously proposed methods, our proposed method hopes to help doctors to classify COVID-19 images more efficiently.
