This paper first shows that for any p∈(1,2)there exists a continuously differentiable function f on l^(p)(and L^(p))such that the proximal subdifferential of f is empty everywhere,and hence it is not suitable to develop theory on proximal subdifferential in the classical Banach spaces l^(P)and L^(P) with p∈(1,2).On the other hand,this paper establishes variational analysis based on the proximal subdifferential in the framework of smooth Banach spaces of power type 2,which conclude all Hilbert spaces and all the classical spaces l^(P)and L^(P)with p∈(2,+∞).In particular,in such a smooth space,we provide the proximal subdifferential rules for sum functions,product functions,composite functions and supremum functions,which extend the basic results on the proximal subdifferential established in the framework of Hilbert *** of our main results are new even in the Hilbert space *** applications,we provide KKT-like conditions for nonsmooth optimization problems in terms of proximal subdifferential.

Dear Editor,Patients undergoing allogeneic hematopoietic stem cell transplantation(HSCT)often experience a significant reduction in immune function due to factors such as severe lymphopenia,immunosuppressive treatment,and the development of graft-versus-host disease,rendering them more susceptible to severe infections(Sahin et al.,2016).Traditional diagnostic approaches are limited in sensitivity,speed,and assay targets,thus failing short of meeting the diagnostic demands(Qu et al.,2022).However,next-generation sequencing(NGS)has greatly improved the accuracy and efficiency of diagnosing various diseases(Schuler et al.,2022),and has been widely utilized for pathogen detection in samples from HSCT patients(Armstrong et al.,2019;Peng et al.,2021).In this study,we employed viral metagenomics analysis using high-throughput sequencing on fecal and tissue samples from a patient with HSCT experiencing severe lingual papillomatosis.

疫情下的城市应急医疗设施布局是一类典型的需求不确定下的多阶段、多类型设施选址,以及资源分配和患者转运的集成优化问题,具有重要研究意义。针对该问题,首先,充分考虑了疫情演化的动态时变特征,采用滚动决策法(rolling-horizon approach)将整个疫情期划分为多个离散决策期,以确保应急决策可根据疫情演化进行实时的优化调整;其次,在每个决策期中又考虑了疫情下的真实需求值基于先前预测值随机扰动的情形,构建了一类涵盖方舱医院、定点医院选址并协同资源分配和患者转运的鲁棒优化模型,将其嵌入滚动决策框架并设计动态求解算法。最后,以2020年初新冠疫情为背景进行算例分析,验证了模型和算法的有效性。

疫情爆发初期,应急部门如何选择应急采购启动时间点并优化采购方案,对提高疫情防控效果意义重大。首先,针对应急采购启动时间点的优选问题,设计了疫情观测停止(或采购启动)最优时间的判断规则,并结合理论分析获得最优停时的边界特征及影响因素;其次,针对采购启动后的采购方案优化问题,综合考虑了不同供应商在订货批量、采购提前期、缺货率方面的差异,并构建一类混合整数规划模型;最后,将上述两问题集成考虑,依据疫情预测、应急效果对比、停时判断、参数更新的循环决策思想,构建一类数据驱动的应急采购框架模型,既确保采购决策以疫情数据为依据,又保证疫情数据被实时更新。结合数值实验可知:通过求解模型,可根据疫情演化来获得应急采购启动时间、供应商选择和订单分配的集成优化方案。
