Congenital heart disease(CHD)is the commonest birth defect,affecting approximately 9.4/1000 live births.^(1)Atrial Septal Defect(ASD)is one of the commonest CHD clinical phenotypes,which frequently requires treatment either in childhood or adulthood,and can lead to severe complications such as right heart failure and cardiac *** genome-wide association studies(GWAS)have identified a region of chromosome 4p16(Ch4p16)associated with the risk of ASD.

浒苔暴发是影响全球近岸海域最为严重的海洋灾害之一,引起了社会各方的重视。该研究基于大气-波浪-海洋集合模式,根据卫星遥感数据提取浒苔位置,采用拉格朗日漂流模式对浒苔进行追踪并预报其漂移路径。与卫星观测结果对比表明,该集合模式能够较好地预报浒苔的位置、分布及其漂移路径。此外,该研究还讨论了Stokes漂流对于模式预报的影响,结果表明考虑Stokes漂流可以修正浒苔漂移路径,有效提高预报的准确性。
