基于病毒-细胞感染和细胞-细胞传播两种机制,研究一类具有胞内时滞,CTL免疫反应和免疫损害的HIV-1感染动力学模型.通过计算得到了病毒感染基本再生率.通过分析特征方程根的分布,讨论了模型的病毒未感染平衡点和慢性感染平衡点的局部稳定性.通过构造适当的Lyapunov泛函并应用LaSalle不变性原理,证明了模型的全局动力学性态由病毒感染基本再生率完全确定:若基本再生率小于1,则病毒未感染平衡点全局渐近稳定;若基本再生率大于1,则慢性感染平衡点全局渐近稳定.进一步,通过数值模拟说明了理论结果,并对参数进行了敏感性分析,确定了参数对病毒感染基本再生率的影响程度.

基于2007—2020年我国A股上市农业企业的微观数据,实证分析数字化转型对农业企业全要素生产率的影响及其机制。研究表明,数字化转型有利于提升农业企业的全要素生产率。机制检验表明,数字化转型通过提高资金利用率、降低超额雇员率、增大研发投入来提高农业企业全要素生产率。调节效应检验表明,营商环境不确定性、行业竞争强度加剧将削减数字化转型对农业企业全要素生产率的提升效果。异质性检验表明,数字化转型对小规模农业企业、处于成长期和成熟期的农业企业、国有农业企业、两职分离的农业企业全要素生产率的提升作用更为显著。为此,政府等治理主体应完善数字基础设施,营造良好营商环境和市场竞争秩序,优化农业企业数字化转型的外部环境;同时农业企业也要根据自身发展实际,科学配置资金、技术、劳动力等资源,选择适宜的数字化转型路径。

In this paper, we consider a susceptible-infective-susceptible(SIS) reaction-diffusion epidemic model with spontaneous infection and logistic source in a periodically evolving domain. Using the iterative technique,the uniform boundedness of solution is established. In addition, the spatial-temporal risk index R0(ρ) depending on the domain evolution rate ρ(t) as well as its analytical properties are discussed. The monotonicity of R0(ρ)with respect to the diffusion coefficients of the infected dI, the spontaneous infection rate η(ρ(t)y) and interval length L is investigated under appropriate conditions. Further, the existence and asymptotic behavior of periodic endemic equilibria are explored by upper and lower solution method. Finally, some numerical simulations are presented to illustrate our analytical results. Our results provide valuable information for disease control and prevention.

Science China(Information Sciences) 2024年第5期67卷 136-149页

Unsupervised domain adaptation(UDA) studies how to transfer a learner from a labeled source domain to an unlabeled target domain with different distributions. Existing methods mainly focus on matching marginal distributions of the source and target domains, which probably leads to a misalignment of samples from the same class but different domains. In this paper, we tackle this misalignment issue by achieving the class-conditioned transferring from a new perspective. Specifically, we propose a method named maximizing conditional independence(MCI) for UDA, which maximizes the conditional independence of feature and domain given class in the reproducing kernel Hilbert spaces. The optimization of conditional independence can be viewed as a surrogate for minimizing class-wise mutual information between feature and domain. An interpretable empirical estimation of the conditional dependence measure is deduced and connected with the unconditional case. Besides, we provide an upper bound on the target error by taking the class-conditional distribution into account, which provides a new theoretical insight for class-conditioned transferring. Extensive experiments on six benchmark datasets and various ablation studies validate the effectiveness of the proposed model in dealing with UDA.
