Service capacity guarantee under the disruption risk of supply chain is a key challenge for the coordinated development of Beijing-Tianjin-Hebei region. Aiming at the characteristics of both random and fuzzy uncertainty of transportation time, this paper proposes an equilibrium optimization model of single allocation hub location based on ambiguous probability distribution. Firstly, by introducing the equilibrium value-at-risk constraint, the uncertainty of transportation time is quantified in the joint form of credibility distribution and probability distribution to ensure that the path transportation time meets the service level requirement. Secondly, the equilibrium optimization model is constructed to minimize the total average transportation time. It is equivalently converted to mixed integer linear programming to realize the efficient solution of the model under trapezoidal fuzzy parameters and normal probability distribution. The case study based on 15 nodes in Beijing-Tianjin-Hebei region shows that compared with the traditional stochastic optimization method, the proposed method can optimize the hub location scheme under dual uncertainty, and the sensitivity of the optimal hub location to the change of confidence level and transportation time limit is significantly improved.The research results provide effective decision support for- DOI:10.3969/j.issn.1000-1565.2025.03.001京津冀供应链中断风险下保障服务能力的枢纽选址策略陈艳菊,殷方浩,刘彦奎(河北大学 数学与信息科学学院,河北 保定 071002)摘 要:供应链中断风险下的服务能力保障是京津冀协同发展的关键挑战.针对运输时间兼具随机与模糊双重不确定性的特征,提出一种基于非精确概率分布的单分配枢纽选址平衡优化模型.首先,通过引入平衡风险值约束,将运输时间的不确定性用可信分布与概率分布的联合形式进行量化,确保路径运输时间满足服务水平要求;其次,以总平均运输时间最小化为目标,构建平衡优化模型,并在梯形模糊参数与正态概率分布下等价转换为混合整数线性规划以实现高效求解.京津冀地区15个节点的案例研究表明:相较于传统随机优化方法,本文方法在双重不确定性下能够有效优化枢纽选址方案,最优枢纽位置对置信水平与运输期限的变化敏感度显著提升.研究结果为复杂不确定环境下区域物流网络优化提供了有效的决策支持.关键词:枢纽选址;平衡优化;双重不确定性;非精确概率分布;京津冀供应链中图分类号:C934 文献标志码:A 文章编号:1000-1565(2025)03-0225-10Hub location strategy for ensuring service capability of supply chain in Beijing-Tianjin-Hebei region under disruption riskCHEN Yanju, YIN Fanghao, LIU Yankui(College of Mathematics and Information Science, Hebei University, Baoding 071002, China)Abstract: Service capacity guarantee under the disruption risk of supply chain is a key challenge for the coordinated development of Beijing-Tianjin-Hebei region.

Pipe-roof structures are frequently utilized in sensitive projects, such as those involving underpasses beneath existing railways and subways, due to their effectiveness in controlling ground disturbance. During the jacking process of pipe-roof installation, deviations may occur due to soil parameters and construction parameters. Excessive deviations can compromise the supporting efficacy of the pipe-roof structure. However, there exists a relative paucity of research specifically addressing deviations during pipe-roof jacking. Based on the transfer passage project, this paper records in real-time the attitude changes during the jacking process of steel pipes, and studies the deviation of the jacked pipeline as well as the closure attitude of pipe sections at different cross-sections. The findings are summarized- DOI:10.3969/j.issn.1000-1565.2025.03.002长距离管幕群顶进管道偏差及闭合姿态分析张晨浩¹,陈思明²,罗嵩²,关振长³,黄金峰²,贾鹏蛟¹(1.苏州大学 轨道交通学院,江苏 苏州 215137;2.中铁南方投资集团有限公司,广东 深圳 518052;3.福州大学 土木工程学院,福建 福州 350108)摘 要:管幕结构因能有效控制地层扰动而常被用于下穿铁路、地铁等敏感工程,群管在顶进过程中,因受土层参数、掘进参数等影响而发生偏差,若偏差过大将影响管幕结构支护效果.依托某换乘通道工程,实时记录了钢管顶进过程中的姿态变化,研究了顶进管道的偏差以及不同断面处管节的闭合姿态.研究表明:1)77.2%钢管偏差在40 mm(钢管直径的5%)及以内,且锁口在垂直于管幕群的方向约束效应更强.随着顶进距离的增大,锁口的约束效应会减弱;2)刚性连接钢管穿越洞口和中段MJS加固区时,表现出明显的刚度效应,积累较大偏差,约70%的顶管出现右偏趋势;3)在顶管的前段整体姿态有波动但仍保持平稳;中段偏差逐渐放大,但最大值控制在65 mm以内,靠近接收井处下排管幕群经过纠偏已经基本归位(竖向偏差均控制在40 mm以内,76.9%钢管水平偏差控制在40 mm以内),上排管幕群偏差平均值在40 mm以内.关键词:管幕;偏差;闭合姿态;约束效应;刚度效应中图分类号:TU447 文献标志码:A 文章编号:1000-1565(2025)03-0235-09Long-distance pipe-roof group jacking pipeline deviation and closure attitude analysisZHANG Chenhao¹, CHEN Siming², LUO Song², GUAN Zhenchang³, HUANG Jinfeng², JIA Pengjiao¹(1.

Furthermore, the locking mechanism exerts a more pronounced restraining effect in the direction perpendicular to the pipe-roof alignment. However, as the jacking distance increases, the constraining influence of the locking mechanism decreases. 2)When rigidly connected steel pipes pass through the tunnel opening and the middle section MJS reinforcement area, they exhibit a significant stiffness effect, accumulating a large deviation, with approximately 70% of the pipe jacking showing a rightward deviation trend. 3)In the initial section of the jacking process, although there are fluctuations in the overall attitude, it remains stable. In the middle section, the deviations within the pipe-roof gradually increase, but the maximum deviation is controlled within 65 mm. The lower pipe-roof group near the receiving shaft has been basically realigned after correction. The vertical deviation is controlled within 40 mm, and 76.9% of the steel pipes have horizontal deviations within 40 mm. The average deviation of the upper pipe-roof group is within 40 mm.

The molecular mechanism of hypersensitivity reactions induced by isoniazid in the treatment of pulmonary tuberculosis was studied using network toxicology methods. Through queries on ChEMBL, STITCH, GeneCards, and OMIM databases, 45 potential targets related to isoniazid and hypersensitivity reactions were identified. Further screening using STRING and Cytoscape software highlighted 11 core targets, including BCL2, CYP3A4, and DRD2. GO and KEGG pathway analysis showed through DAVID and FUMA databases that isoniazid induced hypersensitivity reactions are mainly related to the enrichment of substance metabolism and endocrine pathways. Molecular docking using Autodock confirmed that isoniazid can stably bind to core targets such as BCL2.

Antibiotic therapy is currently the most critical means of controlling bacterial infections. However, antibiotic treatment is a major challenge due to increasing bacterial resistance. Photodynamic antimicrobial therapy(aPDT)uses reactive oxygen species to oxidize biological macromolecules to cause bacterial cell death, so bacteria are not susceptible to aPDT resistance. Antibiotics and aPDT are two different treatments for bacterial infections, both of which have good efficacy, but each has limitations. The combination of aPDT therapy with conventional antibiotics can achieve additive or synergistic therapeutic effects, and the inactivation effect of multidrug-resistant bacteria is more effective than that of a single approach. This article summarizes the current status of common drug-resistant bacterial infections in clinical practice, summarizes the therapeutic effects and mechanisms of different combinations of aPDT and antibiotics, and further points out the advantages, limitations and future development directions of combination therapy with aPDT and antibiotics, aiming to provide guidance for clinical application.- DOI:10.3969/j.issn.1000-1565.2025.03.004光动力抗菌疗法和抗生素联合应用对耐药菌感染的疗效及机制王建国¹,谢佳欣²,孔飞雁³,李昱潼³,赵占娟³(1.河北大学附属医院,检验科,河北 保定 071000;2.河北大学 临床医学院,河北 保定 071000;3.河北大学 基础医学院,河北 保定 071000)摘 要:抗生素治疗是控制细菌感染的关键手段,但随着细菌耐药性的不断增强,抗生素治疗面临着巨大挑战.光动力抗菌疗法(photodynamlc antibacterial therapy,aPDT)利用活性氧氧化生物大分子导致细菌死亡,使细菌不易对aPDT产生耐药性.这2种针对细菌感染的不同治疗方式,均具有良好的疗效,但各自存在局限性.将aPDT治疗与常规抗生素联合使用可实现相加或协同治疗效果,对耐多药细菌的灭活效果超过单一方法.本文概述了临床常见耐药菌感染现况,对aPDT与抗生素不同组合在治疗上的效果和作用机制进行了总结,进一步指出了aPDT与抗生素联合治疗的优势、局限性以及未来发展方向,旨在为临床应用提供指导.关键词:光动力抗菌疗法;多重耐药菌;抗生素;联合治疗中图分类号:R378 文献标志码:A 文章编号:1000-1565(2025)03-0254-12Efficacy and mechanism of the combined application ofphotodynamic antibacterial therapy and antibioticon drug-resistant bacterial infectionWANG Jianguo¹, XIE Jiaxin², KONG Feiyan³, LI Yutong³, ZHAO Zhanjuan³(1.

We investigated the effects of UiO-66-SH on the growth and development of hydroponically grown Brassica chinensis under different concentrations of arsenic(As)and cadmium(Cd)stress. By measuring indicators such as the biomass of Pakchoi, the level of heavy metal enrichment, the content of malondialdehyde(MDA). and the activities of antioxidant enzymes, the adsorption mechanism of UiO-66-SH towards the combined pollution of arsenic and cadmium was analyzed.The results showed that the fresh and dry weights of both above-ground and below-ground parts of Brassica chinensis decreased with- DOI:10.3969/j.issn.1000-1565.2025.03.006砷镉胁迫下UiO-66-SH对水培小白菜生长发育的影响王焱¹,陈芯怡¹,张凌荔¹,王鑫宇²,何铁光³,张拓²(1.西华师范大学 环境科学与工程学院,四川 南充 637000;2.南宁师范大学 环境与生命科学学院,广西 南宁 530001; 3. 广西农业科学院 农业资源与环境研究所,广西耕地保育重点实验室,广西 南宁 530007)摘 要:本文对砷(As)镉(Cd)胁迫下,UiO-66-SH对水培小白菜生长发育的影响进行了研究.通过测定小白菜的生物量、重金属富集水平、丙二醛(MDA)含量及抗氧化酶活性等指标,分析了UiO-66-SH对As、Cd复合污染的吸附机制.结果表明:随着As和Cd浓度的升高,小白菜地上部分和地下部分的鲜质量与干质量均有所下降,而UiO-66-SH的添加使下降趋势明显减弱.此外,UiO-66-SH添加后还促进了小白菜根长、株高及叶片展幅的生长,尤其在低质量浓度组处理下更为显著;在重金属富集方面,UiO-66-SH对水体中的As和Cd显示出良好的吸附性能,低质量浓度组和高质量浓度组中,小白菜对Cd的吸附率分别为69.5%和60.2%,对As的吸附率分别为71.1%和63.1%,显著降低了小白菜对As和Cd的吸收和富集,从而减少了重金属对小白菜的毒害作用;此外,UiO-66-SH通过降低MDA含量及SOD、POD、CAT、APX活性,缓解了氧化损伤,并且UiO-66-SH通过Zr—O—H和S—H键与As、Cd的络合作用,在材料表面形成了更加稳定的Zr—O—As和S—Cd键,从而实现了同步去除.研究表明,UiO-66-SH在缓解As和Cd胁迫对小白菜生长发育的抑制作用方面具有显著效果,是一种具有广阔应用前景的环境功能材料.关键词:砷镉胁迫;UiO-66-SH;小白菜;重金属吸附中图分类号:A53 文献标志码:A 文章编号:1000-1565(2025)03-0278-11Effects of UiO-66-SH on the growth and development of Brassica chinensis under arsenic and cadmium stresses in water-planting condition WANG Yan¹, CHEN Xinyi¹, ZHANG Lingli¹, WANG Xinyu², HE Tieguang³, ZHANG Tuo²(1.College of Environmental Science and Engineering, China West Normal University, Nanchong 637000, China; 2.School of Environment and Life Science, Nanning Normal University, Nanning 530001, China; 3.

In addition, the addition of UiO-66-SH also promoted the growth of Brassica chinensis root length, plant height and leaf spreading, especially in the low concentration of the treatment was more significant; in heavy metal enrichment, UiO-66-SH showed good adsorption performance on As and Cd in the water body, the adsorption rate of Cd reached 69.5% and 60.2% in the low and high concentration treatments, respectively, the adsorption rate of As reached 71.1% and 63.1%, this adsorption significantly reduced the absorption and enrichment of As and Cd in Brassica chinensis, thus reducing the toxic effects of heavy metals on Brassica chinensis; Furthermore, UiO-66-SH alleviated oxidative damage by reducing the content of MDA and the increases in the activities of superoxide dismutase(SOD), peroxidase(POD), catalase(CAT), and ascorbate peroxidase(APX). The results indicated that the synchronous adsorption process of UiO-66-SH on arsenic and cadmium is mainly through the action of Zr—O—H and S—H bonds, and through the way of ligand complexation, more stable Zr—O—As and S—Cd bonds are formed on the surface of the material, thus achieving synchronous removal. In summary, the present study demonstrated that UiO-66-SH has a significant effect in alleviating the inhibitory effects of As and Cd stress on the growth and development of Brassica chinensis, and it is a kind of environmentally functional material with promising applications in the future.

To address the data imbalance problem in wind speed forecast correction, a correction model based on a classification/regression hierarchical structure is proposed. The core idea of this model is to adopt a divide-and-conquer strategy to gradually address the data imbalance in wind speed data. In the classification layer, a reweighting strategy is used to preliminarily address the data imbalance. In the regression layer, a group-wise expansion training strategy is proposed to effectively correct samples incorrectly classified due to imbalance, further addressing the data imbalance issue. Additionally, a probability weighting method based on a greedy strategy is designed to provide more accurate predictions for confident samples. The corrected wind speed forecasts showed a 34.4% reduction in overall Mean Absolute Error, with a 69.0% reduction for extreme wind speed events, indicating that the model not only improves the prediction accuracy for extreme wind speed events but also maintains performance in predicting stable events.

In order to improve the discriminant performance of the feature representation in the vehicle re-identification task,most of the current methods enrich the discriminant information by extracting the global information and local information of the vehicle respectively through the multi-branch structure,this will not only increase the network parameters, but also consume a lot of time.In order to solve the above problems,a vehicle re-identification method based on cross-layer attention and multiple memory units is proposed. Firstly, a cross-layer attention module is proposed to extract shallow global texture information and deep local semantic information in a single branch network,and then the cross-layer attention mechanism is used to assign weights to fuse the information of different layers.Then, the instance memory and the class memory are constructed to store the instance and class features respectively,and the influence of noise samples on feature representation is reduced by identity loss based on multiple memory.The experimental results show that the mAP,CMC@1 and CMC@5 of the proposed method on VeRi-776 dataset increase by- DOI:10.3969/j.issn.1000-1565.2025.03.011基于跨层注意力与多记忆单元的车辆重识别方法齐玉亮^{1, 2},王伟明²,王静³,熊彦臻⁴,李慧⁴(1.河北大学 河北省机器视觉工程研究中心,河北 保定 071002;2.河北高速公路集团有限公司 京雄分公司,河北 高碑店 074004;3.河北省交通运输运行监测与信息服务中心,河北 石家庄 050031;4.河北大学 网络空间安全与计算机学院,河北 保定 071002)摘 要:为了提高车辆重识别任务中特征表示的判别性能,目前大部分方法通过多分支结构来分别提取车辆的全局信息和局部细节信息,这样不仅会增加网络参数,同时还会消耗大量的时间.为了解决上述问题,提出了一种基于跨层注意力与多记忆单元的车辆重识别方法.首先,提出一种跨层注意力模块提取单分支网络中浅层的局部空间信息和深层的全局语义信息,再通过跨层注意力机制分配权重来融合不同层的信息,构建实例记忆单元和类别记忆单元来分别储存实例级特征和类别级特征,并通过基于多记忆单元的身份损失来削弱噪声样本对特征表示的影响.实验结果表明,所提出方法在VeRi-776数据集上的mAP、CMC@1、CMC@5相比于基线网络分别提高了1.5%、0.3%、0.1%.在VehicleID数据集中测试集大小为800、1 600、2 400时CMC@1相比于基线网络分别提高了1.9%、2.8%、3.8%.关键词:跨层注意力;实例记忆单元;类别记忆单元;车辆重识别中图分类号:TP183 文献标志码:A 文章编号:1000-1565(2025)03-0327-10Vehicle re-identification based on cross-layer attention and multi-memoryQI Yuliang^1,2, WANG Weiming², WANG Jing³, XIONG Yanzhen⁴, LI Hui⁴(1.
