In this paper,we undertake further investigation to alleviate the issue of limit cycling behavior in training generative adversarial networks(GANs)through the proposed predictive centripetal acceleration algorithm(PCAA).Specifically,we first derive the upper and lower complexity bounds of PCAA for a general bilinear game,with the last-iterate convergence rate notably improving upon previous ***,we combine PCAA with the adaptive moment estimation algorithm(Adam)to propose PCAA-Adam,for practical training of GANs to enhance their generalization ***,we validate the effectiveness of the proposed algorithm through experiments conducted on bilinear games,multivariate Gaussian distributions,and the CelebA dataset,respectively.

Floating periodic pontoons for broad bandgaps of water waves

引用

applied Mathematics and Mechanics(English Edition) 2024年第11期45卷 1913-1928页

作者： Huaqing JIN Haicheng ZHANG Ye LU Daolin XU College of Mechanical and Vehicle Engineering Hunan University Wuxi lntelligent Control research Institute Hunan University China Ship scientific research Center

The narrow attenuation bands of traditional marine structures have long been a challenge in mitigating water waves. In this paper, a metastructure(MS) composed of floating periodic pontoons is proposed for broadband water wave attenuation. The interaction of surface gravity waves with the MS is investigated using linear wave *** potential solutions of water waves by the MS with a finite array are developed by using the eigenfunction expansion matching method(EEMM), and the band structure of the MS is calculated by the transfer matrix method(TMM), in which the evanescent modes of waves are considered. The solution is verified against the existing numerical result for a special case. Based on the present solution, the association between Bragg resonance reflection and Bloch bandgaps is examined, the effects of pontoon geometry are analyzed,and the comparison between floating MS and bottom-mounted periodic structures is conducted. A computational fluid dynamics(CFD) model is further developed to assess the structures in practical fluid environments, and the floating MS presents excellent wave attenuation performance. The study presented here may provide a promising solution for protecting the coast and offshore structures.

Artificial intelligence strengthenes cervical cancer screening–present and future

引用

Cancer Biology & Medicine 2024年第10期 864-879页

作者： Tong Wu Eric Lucas Fanghui Zhao Partha Basu Youlin Qiao School of Population Medicine and Public Health Chinese Academy of Medical Sciences and Peking Union Medical College Early Detection Prevention & Infections Branch International Agency for Research on Cancer (WHO) Department of Cancer Epidemiology National Cancer Center/National Clinical Research Center for Cancer/Cancer Hospital Chinese Academy of Medical Sciences and Peking Union Medical College

Cervical cancer is a severe threat to women's health. The majority of cervical cancer cases occur in developing countries. The WHO has proposed screening 70% of women with high-performance tests between 35 and 45 years of age by 2030 to accelerate the elimination of cervical cancer. Due to an inadequate health infrastructure and organized screening strategy, most low-and middleincome countries are still far from achieving this goal. As part of the efforts to increase performance of cervical cancer screening, it is necessary to investigate the most accurate, efficient, and effective methods and strategies. Artificial intelligence(AI) is rapidly expanding its application in cancer screening and diagnosis and deep learning algorithms have offered human-like interpretation capabilities on various medical images. AI will soon have a more significant role in improving the implementation of cervical cancer screening, management, and follow-up. This review aims to report the state of AI with respect to cervical cancer screening. We discuss the primary AI applications and development of AI technology for image recognition applied to detection of abnormal cytology and cervical neoplastic diseases, as well as the challenges that we anticipate in the future.
