李伟1,杨波威1,宋广华1,姜晓红2

《信息与电子工程前沿（英文）》 2021年第22卷第5期页码 615-766 doi: 10.1631/FITEE.1900712

摘要：为规划快速变化的无人机群，本文提出一种动态值迭代网络（DVIN）模型，该模型利用无人机自组网的连接信息，采用场景式Q学习方法训练，生成状态值传播函数，使无人机节点能够自适应调节至新的物理位置。然后，评估了动态值迭代网络模型的性能，并将其与非支配排序遗传算法NSGA-II和穷举法比较。仿真结果表明，动态值迭代网络模型显著缩短了无人机节点路径规划的决策时间，且平均成功率更高。

《结构与土木工程前沿（英文）》 2014年第8卷第4期页码 448-455 doi: 10.1007/s11709-014-0262-x

摘要： Rock mass classification system is very suitable for various engineering design and stability analysis. classification method is confirmed by Japan Highway Public Corporation that this method can figure out either strength or deformability of rock mass, further appropriating the amount of rock bolts, thickness of shotcrete, and size of pitch of steel ribs just after the blasting procedure. Based on these advantages of method, in this study, according to data of five deep and long tunnels in Iran, two equations for estimating the value of method from and classification systems were developed. These equations as a new method were able to optimize the support system for and classification systems. From classification and its application in these case studies, it is pointed out that the method for the design of support systems in underground working is more reliable than the and classification systems.

An approach for evaluating fire resistance of high strength Q460 steel columns

Wei-Yong WANG, Guo-Qiang LI, Bao-lin YU

《结构与土木工程前沿（英文）》 2014年第8卷第1期页码 26-35 doi: 10.1007/s11709-014-0239-9

摘要： To develop a methodology for evaluating fire resistance of high strength Q460 steel columns, the load bearing capacity of high strength Q460 steel columns is investigated. The current approach of evaluating load bearing capacity of mild steel columns at room temperature is extended to high strength Q460 steel columns with due consideration to high temperature properties of high strength Q460 steel. The critical temperature of high strength Q460 steel column is presented and compared with mild steel columns. The proposed approach was validated by comparing the predicted load capacity with that evaluated through finite element analysis and test results. In addition, parametric studies were carried out by employing the proposed approach to study the effect of residual stress and geometrical imperfections. Results from parametric studies show that, only for a long column (slenderness higher than 75), the magnitude and distribution mode of residual stress have little influence on ultimate load bearing capacity of high strength Q460 steel columns, but the geometrical imperfections have significant influence on any columns. At a certain slenderness ratio, the stability factor first decreases and then increases with temperature rise.

《信息与电子工程前沿（英文）》 2021年第22卷第11期页码 1441-1550 doi: 10.1631/FITEE.2000590

摘要：本文提出“四值QCA（QQCA）”新概念。该概念已在本团队专为四值QCA模型开发的量子点细胞自动模拟器（QCASim）中设定。设计了基本四值QCA逻辑门，如MIN、MAX和不同类型反相器（SQI，PQI，NQI和IQI），并通过QCASim验证。本文将例示QCASim如何通过其方便的CAD工具集快速而准确地工作。将QQCA主要的逻辑门与基于碳纳米管场效应晶体管（CNFET）的四值门进行比较，结果表明本文所设计的电路具有更小延迟和更低能耗。

R158Q and G212S, novel pathogenic compound heterozygous variants in of Gitelman syndrome

《医学前沿（英文）》 2022年第16卷第6期页码 932-945 doi: 10.1007/s11684-022-0963-9

摘要： The dysfunction of Na⁺-Cl⁻ cotransporter (NCC) caused by mutations in solute carrier family12, member 3 gene (SLC12A3) primarily causes Gitelman syndrome (GS). In identifying the pathogenicity of R158Q and G212S variants of SLC12A3, we evaluated the pathogenicity by bioinformatic, expression, and localization analysis of two variants from a patient in our cohort. The prediction of mutant protein showed that p.R158Q and p.G212S could alter protein’s three-dimensional structure. Western blot showed a decrease of mutant Ncc. Immunofluorescence of the two mutations revealed a diffuse positive staining below the plasma membrane. Meanwhile, we conducted a compound heterozygous model—Ncc R156Q/G210S mice corresponding to human NCC R158Q/G212S. Ncc^R156Q/G210S mice clearly exhibited typical GS features, including hypokalemia, hypomagnesemia, and increased fractional excretion of K⁺ and Mg²⁺ with a normal blood pressure level, which made Ncc^R156Q/G210S mice an optimal mouse model for further study of GS. A dramatic decrease and abnormal localization of the mutant Ncc in distal convoluted tubules contributed to the phenotype. The hydrochlorothiazide test showed a loss of function of mutant Ncc in Ncc^R156Q/G210S mice. These findings indicated that R158Q and G212S variants of SLC12A3 were pathogenic variants of GS.

用于语音识别的二值神经网络 Regular Papers

Yan-min QIAN, Xu XIANG

《信息与电子工程前沿（英文）》 2019年第20卷第5期页码 701-715 doi: 10.1631/FITEE.1800469

摘要：为降低推理阶段计算量，本文开发了用于语音识别的二进制神经网络，并实现了高速的二值矩阵乘法。在中央处理器(CPU)和图形处理单元(GPU)上，二值矩阵乘法的运行速度是浮点矩阵乘法的5–7倍。针对大规模连续语音识别的声学建模，提出多种二值神经网络及相关模型优化算法。为提高二值模型的精度，探索了从浮点模型到二值模型的知识蒸馏技术。在标准的Switchboard语音识别任务上，该二值神经网络模型比浮点神经网络模型速度提高3–4倍。借助知识蒸馏技术，二值深度神经网络或卷积神经网络相对其浮点神经网络的词错误率增加可以保持在15%以内。若只二值化卷积神经网络的卷积层，词错误率增加几乎可忽略。

项目进度管理中基于挣值的随机工期分析 Review

Fernando Acebes, David Poza, José Manuel González-Varona, Adolfo López-Paredes

《工程（英文）》 2022年第9卷第2期页码 148-162 doi: 10.1016/j.eng.2021.07.019

摘要：

挣值工期管理（EDM）是一种用于项目进度管理（PSM）的研究方法，当无法使用挣值管理（EVM）时，可以考虑这种方法。挣值工期管理用于估算进度偏差和最终项目工期。挣值工期管理和挣值管理的关键区别在于：在挣值工期管理中，用工作周期表示活动的值；而在挣值管理中，用成本表示活动的值。本文将展示如何使用挣值工期管理监控随机项目。为便于解释该方法，本文通过实例分析对呈现出高度不确定性的项目开展研究，项目中的各项活动采用随机工期。根据这些活动的网络拓扑分析该方法的可用性，并比较了挣值管理和挣值进度分析法（ESM）对项目进度管理的作用。

A rare case of B-lymphoproliferative disorder with villous lymphocytes harboring t(8;14)(q24;q32) translocation

null

《医学前沿（英文）》 2018年第12卷第3期页码 324-329 doi: 10.1007/s11684-017-0558-z

摘要：

Splenic lymphoma with villous lymphocytes (SLVL) or splenic marginal zone lymphoma with circulating villous lymphocytes is rare, and prolymphocytic transformation of SLVL is rarer. At present, only one case of SLVL with t(8;14)(q24;q32) translocation has been reported. In this study, we report a case of B-lymphoproliferative disorder with villous lymphocytes harboring t(8;14)(q24;q32) chromosome translocation that we inclined to SLVL with a prolymphocytic transformation. A 73-year-old female showed marked hepatosplenomegaly and high lymphocytosis (lymphocytes>200×10⁹/L). The abnormal lymphocytes had short coarse villi and round nuclei with prominent nucleoli. The immunophenotypes showed CD19⁺, CD20⁺, HLA-DR⁺, CD22⁺, CD5⁺, Kappa⁺, CD25^dim, CD71^dim, Lambda⁻, CD7⁻, CD10⁻, CD23⁻, CD34⁻, CD33⁻, CD13⁻, CD14⁻, CD117⁻, CD64⁻, CD103⁻, and CD11c⁻. The karyotype showed complex abnormality: 46XX,+3,−10, t(8;14)(q24;q32)[11]/46XX[⁹]. The cytoplasmic projection, immunological characteristics, and trisomy 3 chromosome abnormality supported the diagnosis of SLVL. However, the presence of prominent nucleoli and high lymphocytosis suggested prolymphocytic transformation, probably as a result of t(8,14) chromosome translocation. In this report, we described an unusual case of B-lymphoproliferative disorder with villous lymphocytes harboring t(8;14)(q24;q32) translocation, which could provide help in the diagnosis and differential diagnosis of B-lymphocytic proliferative diseases.

Hot deformation behavior of a novel bimetal consisting of BTW1 and Q345R characterized by processing

Pengtao LIU, Lifeng MA, Weitao JIA, Tao WANG, Guanghui ZHAO

《机械工程前沿（英文）》 2019年第14卷第4期页码 489-495 doi: 10.1007/s11465-019-0554-x

摘要： Only a few studies have been conducted on the flow behavior of the novel BTW1/Q345R bimetal, which is widely used in coal equipment. In this work, compression tests were conducted on BTW1/Q345R bimetal at a temperature range of 950 °C–1200 °C and strain rates of 0.05, 0.5, 5, and 15 s by using a Gleeble-3800 thermomechanical simulator. A constitutive equation was validated by referring to the Arrhenius equation during the characterization of hot workability. The computed apparent activation energy of the BTW1/Q345R bimetal was 360 kJ/mol, and processing maps under different strain conditions were drawn. Analysis of the stress-strain relationship revealed that work hardening exerted a dominant effect on the thermal deformation of the BTW1/Q345R bimetal. The processing maps predicted that the optimal processing interval will increase with strain. Results showed that thermal deformation of the BTW1/Q345R bimetal should proceed when the temperature range varies from 1182 °C to 1200 °C and the strain rate interval is from 4.2 to 15 s .
