Dear Editor,Human immunodeficiency virus(HIV)is a lentivirus that,if left untreated,can lead to acquired immunodeficiency syndrome(AIDS).The virus can be divided into two types based on genetic differences:HIV-1 and ***-1 is widely distributed worldwide and is the primary strain responsible for the global AIDS epidemic due to its high replication capacity,greater likelihood of transmission,and more severe clinical symptoms(Oeschger et al.,2021).

Dear Editor,Brassica carinata(Bc Bc Cc Cc),an important agricultural crop cultivated for the edible oil,leafy vegetable,high-value protein stockfeed,and biofuel markets,contains favorable genetic variation that can be exploited to develop climate-resilient and wateruse-efficient Brassica crops(Seepaul et al.,2021).Although several quantitative trait loci(QTLs)for flowering time,seed quality traits,and pod shatter resistance(PSR)have been identified based on high-density genetic linkage maps(Zou et al.,2014;Raman et al.,2017;Zhang et al.,2017),this information alone is insufficient for practical genetic improvement and breeding applications.

金融科技是打造现代商业银行和推进金融强国建设的重要内容。采用SFA模型测度商业银行经营效率,考察金融科技对传统商业银行体系的影响。研究发现,金融科技整体上降低了商业银行经营效率。中介检验表明,金融科技会通过挤压商业银行利差降低收入效率,通过加重风险承担抑制成本效率。调节效应检验发现,商业银行开展数字化转型与多元化经营均可以有效缓解金融科技对经营效率的负面冲击。非线性检验发现,长远看来,金融科技与商业银行经营效率存在U形关系,技术溢出效应会随金融科技发展而逐渐增强,最终促进效率提升。为此,需要继续推进金融科技发展,鼓励商业银行开展数字化转型,强化技术溢出效应的正向影响,弱化外部竞争效应带来的负面冲击,有效防控金融科技风险,做好数字金融这篇大文章。

忆阻器可以用来模拟生物神经突触和描述电磁感应效应.为了探索电磁感应作用下异构神经网络的动力学行为,本文首先使用双局部有源忆阻器耦合一个Hindmarsh-Rose (HR)和两个FitzHugh-Nagumo (FN)神经元,构成忆阻电磁感应下分数阶异构神经网络.然后利用相图、分岔图、李雅普诺夫指数谱和吸引盆等动力学分析方法,对该网络进行数值研究.结果表明该神经网络表现出丰富的动力学行为,包括共存行为、反单调现象、瞬态混沌和放电行为等,为研究人脑放电行为提供支持,随后进一步利用时间反馈控制方法实现了双稳态的控制.最后,在嵌入式硬件平台上实现了该神经网络,验证了仿真结果的有效性.
