| 1 | Automatic Detection of COVID-19 Infection Using Chest X-Ray Images Through Transfer Learning显示文摘The new coronavirus(COVID-19),declared by the World Health Organization as a pandemic,has infected more than 1 million people and killed more than 50 thousand.An infection caused by COVID-19 can develop into pneumonia,which can be detected by a chest X-ray exam and should be treated appropriately.In this work,we propose an automatic detection method for COVID-19 infection based on chest X-ray images.The datasets constructed for this study are composed of194 X-ray images of patients diagnosed with coronavirus and 194 X-ray images of healthy patients.Since few images of patients with COVID-19 are publicly available,we apply the concept of transfer learning for this task.We use different architectures of convolutional neural networks(CNNs)trained on Image Net,and adapt them to behave as feature extractors for the X-ray images.Then,the CNNs are combined with consolidated machine learning methods,such as k-Nearest Neighbor,Bayes,Random Forest,multilayer perceptron(MLP),and support vector machine(SVM).The results show that,for one of the datasets,the extractor-classifier pair with the best performance is the Mobile Net architecture with the SVM classifier using a linear kernel,which achieves an accuracy and an F1-score of 98.5%.For the other dataset,the best pair is Dense Net201 with MLP,achieving an accuracy and an F1-score of 95.6%.Thus,the proposed approach demonstrates efficiency in detecting COVID-19 in X-ray images. | Elene Firmeza Ohata Gabriel Maia Bezerra João Victor Souza das Chagas Aloísio Vieira Lira Neto Adriano Bessa Albuquerque Victor Hugo Cde Albuquerque Pedro Pedrosa Rebouças Filho | 2021 | IEEE/CAA Journal of Automatica Sinica2021，8，1： | 3 |

| 18 | 敏定偶用于35岁以上妇女的疗效、安全性和周期控制显示文摘口服避孕药在投放市场之初,应用于各种年龄段的妇女.然而资料显示早期使用的高剂量口服避孕药会增加心肌梗塞的发病率[1];在1975年,美国食品药物管理局(FDA)不建议40岁以上的妇女服用避孕药,对30岁以上的吸烟妇女建议她们要么停止吸烟要么改换避孕方式[2].随着研究的进一步深入[3]及低剂量口服避孕药的问市,已证实任何年龄的非吸烟妇女服用避孕药不会增加发病率.因此,FDA取消了对非吸烟者服用避孕药的年龄限制. | Andrade RP Auigar LF Adrighi JM Barbosa IC Bossemeyer RP Hegg R Leaf JWB Neto LS Pereira AS Vara A | 2001 | 中国计划生育学杂志2001，9，2： | 0 |
