以西巢湖为研究对象,通过室内模拟实验向已疏浚柱状样添加镧改性膨润土(LMB,商品名Phoslock■)、铜锈环棱螺、河蚬及螺蚬组合,研究钝化材料和底栖动物强化疏浚效果.采用平衡式间隙水技术(Peeper)测定间隙水NH_(4)^(+)-N和可溶性活性磷(SRP)浓度并计算沉积物-水界面交换通量,通过分级提取实验分析底泥磷形态.结果显示,在疏浚的基础上添加Phoslock,上覆水TP、SRP浓度及间隙水NH_(4)^(+)-N、SRP扩散通量显著下降,TN浓度上升为疏浚组的1.3倍.投加底栖动物相较于疏浚组上覆水氮、磷浓度及间隙水NH_(4)^(+)-N扩散通量均有不同程度的上升,SRP扩散通量下降了3.6%~53.6%.Phoslock和底栖动物均能进一步减少沉积物中TN、TP和OM的含量,削减范围分别为4.8%~12.3%、14.2%~39.2%和4.5%~20.1%.磷形态结果表明,Phoslock和河蚬可以削减沉积物中活性磷在总磷的占比,削减量分别为25.9%和22.4%,而加入铜锈环棱螺沉积物中活性磷占比为疏浚组的1.3倍.以上结果表明,Phoslock能够进一步强化疏浚对沉积物中氮、磷的控制效果;加入底栖动物降低了沉积物中污染物含量及间隙水中SRP扩散通量,但上覆水氮、磷浓度及界面NH_(4)^(+)-N扩散通量有所升高,强化疏浚效果并不理想.

QTL mapping and QTL × environment interaction analysis of multi-seed pod in cultivated peanut(Arachis hypogaea L.)

引用

The Crop Journal 2019年第2期7卷 249-260页

作者： Liang Wang xinlei yang Shunli Cui Guojun Mu Xingming Sun Lifeng Liu Zichao Li Key Lab of Crop Heterosis and Utilization Ministry of Education Beijing Key Lab of Crop Genetic Improvement China Agricultural University College of Agronomy Hebei Agricultural University North China Key Laboratory for Crop Germplasm Resources of Education Ministry Crop Research Institute Xinjiang Academy of Agricultural and Reclamation Science

To dissect the genetic mechanism of multi-seed pod in peanut, we explored the QTL/gene controlling multi-seed pod and analyzed the interaction effect of QTL and environment. Two hundred and forty eight recombinant inbred lines(RIL) from cross Silihong × Jinonghei 3 were used as experimental materials planted in 8 environments from 2012 to 2017. Three methods of analysis were performed. These included individual environment analysis, joint analysis in multiple environments, and epistatic interaction analysis for multi-seed pod QTL. Phenotypic data and best linear unbiased prediction(BLUP) value of the ratio of multi-seed pods per plant(RMSP) were used for QTL mapping. Seven QTL detected by the individual environmental mapping analysis and were distributed on linkage groups 1, 6, 9, 14, 19(2), and 21. Each QTL explained 4.42%–11.51% of the phenotypic variation in multi-seed pod, and synergistic alleles of5 QTL were from the Silihong parent. One QTL, explaining 4.93% of the phenotypic variation was detected using BLUP data, and this QTL mapped in the same interval as q RMSP19.1 detected in the individual environment analysis. Seventeen additive QTL were identified by joint analysis across multiple environments. A total of 43 epistatic QTL were detected by ICIM-EPI mapping in the multiple environment trials(MET) module, and involved 57 loci. Two main-effect QTL related to multi-seed pod in peanut were filtered. We also found that RMSP had a highly significant positive correlation with pod yield per plant(PY), and epistatic effects were much more important than additive effects. These results provide theoretical guidance for the genetic improvement of germplasm resources and further fine mapping of related genes in peanut.

Decentralized Federated Learning Algorithm Under Adversary Eavesdropping

IEEE/CAA Journal of Automatica Sinica 2025年第2期12卷 448-456页

作者： Lei Xu Danya Xu xinlei Yi Chao Deng Tianyou Chai Tao yang the State Key Laboratory of Synthetical Automation for Process Industries Northeastern University the Department of Mechanical Engineering University of Victoria Shanghai Institute of Intelligent Science and Technology Tongji University IEEE the Institute of Advanced Technology Nanjing University of Posts and Telecommunications

In this paper, we study the decentralized federated learning problem, which involves the collaborative training of a global model among multiple devices while ensuring data *** classical federated learning, the communication channel between the devices poses a potential risk of compromising private information. To reduce the risk of adversary eavesdropping in the communication channel, we propose TRADE(transmit difference weight) concept. This concept replaces the decentralized federated learning algorithm's transmitted weight parameters with differential weight parameters, enhancing the privacy data against eavesdropping. Subsequently, by integrating the TRADE concept with the primal-dual stochastic gradient descent(SGD)algorithm, we propose a decentralized TRADE primal-dual SGD algorithm. We demonstrate that our proposed algorithm's convergence properties are the same as those of the primal-dual SGD algorithm while providing enhanced privacy protection. We validate the algorithm's performance on fault diagnosis task using the Case Western Reserve University dataset, and image classification tasks using the CIFAR-10 and CIFAR-100 datasets,revealing model accuracy comparable to centralized federated learning. Additionally, the experiments confirm the algorithm's privacy protection capability.

煤炭质量核心指标的估算有利于煤炭质量的管控,并为智能开采、分质开采提供科学依据。将克里金插值法引入到煤质指标估算模型的建立,利用差分进化算法求解其变差函数的模型参数;针对在差分进化过程中因“早熟”现象导致最优解被破坏的问题,在变异过程中设计可动态修正变异方向的缩放因子,提出修正变异方向的自适应差分进化算法(UMDE)来确定变差函数的模型参数,并用该方法对煤矿井下未开采区域的全水分进行克里金插值。通过交叉验证与对比实验,证明基于自适应差分克里金方法(UMDE-Kriging)构建的煤质指标估算模型较其他优化方案在估算精度上有显著提升。
