| 1 | D2D Multicast Retransmission Algorithm in Mobile Cloud Based on SINR Constraint显示文摘In cellular network, users with same demand and in proximity to each other form the mobile cloud, in which the short-range D2 D technology is employed by users to improve the data dissemination efficiency. In view of the fact that the D2 D links with the poor channel conditions are likely to be the bottleneck of resource utilization improvement, aiming at the differentiation of link quality, this paper proposes a intra-cloud D2 D multicast retransmission algorithm based on SINR constraint to meet the minimum requirement of D2 D retransmission for Qo S. In the proposed algorithm, the model of system link cost is built, the number of multicast retransmission times is restricted and each link quality matrix is traversed to reasonably select the multicast transmitter as well as its routing, which further reduces the link cost consumption, and in turn improves the bandwidth efficiency. Simulation results show that the proposed algorithm is more efficient to improve the bandwidth utilization when the ratio between normal user and non-normal user is small in mobile cloud. | Zufan Zhang Lisha Luo Lisha Wang | 2016 | China Communications2016，13，8： | 4 |
| 2 | Energy Efficiency Based on Joint Data Packet Fragmentation and Cooperative Transmission显示文摘Energy efficiency(EE) is a key requirement for the design of short-range communication network.In order to alleviate energy consumption(EC) constraint,a novel layered heterogeneous mobile cloud architecture is proposed in this paper.Based on the proposed layered heterogeneous mobile cloud architecture,we establish an appropriate energy consumption model,and design an energy efficiency scheme based on joint data packet fragmentation and cooperative transmission and analyze the energy efficiency corresponding to different packet sizes and the cloud size.Simulation results show that,when all nodes of the cloud are accessing the same size of data packet fragmentation,the proposed layered heterogeneous mobile cloud architecture can provide significant energy savings.The results provide useful insights into the possible operation of the strategies and show that significant energy consumption reductions are possible. | ZHANG Zufan YI Yinxue YANG Jing JING Xiaorong | 2014 | China Communications2014，11，10： | 3 |
| 3 | Identifying influential nodes in social networks via community structure and influence distribution difference显示文摘This paper aims to effectively solve the problem of the influence maximization in social networks.For this purpose,an influence maximization method that can identify influential nodes via the community structure and the influence distribution difference is proposed.Firstly,the network embedding-based community detection approach is developed,by which the social network is divided into several high-quality communities.Secondly,the solution of influence maximization is composed of the candidate stage and the greedy stage.The candidate stage is to select candidate nodes from the interior and the boundary of each community using a heuristic algorithm,and the greedy stage is to determine seed nodes with the largest marginal influence increment from the candidate set through the sub-modular property-based Greedy algorithm.Finally,experimental results demonstrate the superiority of the proposed method compared with existing methods,from which one can further find that our work can achieve a good tradeoff between the influence spread and the running time. | Zufan Zhang Xieliang Li Chenquan Gan | 2021 | Digital Communications and Networks2021，7，1： | 2 |

| 7 | 家蚕追寄蝇谷胱甘肽硫转移酶GST1-1的特性分析及其在灭蚕蝇胁迫下的活性变化显示文摘家蚕追寄蝇(Exorista sorbillans Wiedemann)寄生家蚕幼虫导致蝇蛆病的发生。谷胱甘肽硫转移酶(glutathione S-transferase, GST)是一类多功能酶家族,对昆虫在解毒、杀虫剂抗性、氧化应激保护等方面起到重要的作用。本文以家蚕追寄蝇为实验材料,使用RACE技术,获得了家蚕追寄蝇谷胱甘肽硫转移酶基因的全长cDNA序列,将其命名为EsGST1-1(GenBank:OK104864)。EsGST1-1全长813 bp,包含一段627 bp完整开放阅读框(ORF),编码208个氨基酸残基,分子质量为23.58 kD,等电点为5.498,该蛋白属于GST的Delta类家族。序列比对结果显示,EsGST1-1与丝光绿蝇(Lucilia sericata)的GST基因亲缘关系最近。进一步检测了家蚕追寄蝇EsGST1-1基因在不同发育时期和不同组织的表达模式,结果显示在卵产后0 h、幼虫脂肪体和表皮、蛹期第6天以及雌雄成虫的腹部与足部中EsGST1-1高量表达。此外,利用原核体外诱导表达获得了EsGST1-1的重组蛋白。酶活试验结果显示EsGST1-1酶活性为0.820 4 U/mg。热稳定性实验结果显示EsGST1-1在30~40℃时活性最高,随温度的升高活性下降。对灭蚕蝇胁迫下的GST活性测定发现:杀虫活性呈剂量依赖效应;寄蝇谷胱甘肽硫转移酶活力与灭蚕蝇剂量呈负相关;EsGST1-1基因的表达量与灭蚕蝇剂量呈负相关。上述研究结果为进一步开发防治蝇蛆病新型药剂提供基础信息。 | 王闪闪 王耒耒 陈诺婧依 Zufan Bekele Kassa 张彩红 王梅仙 朱娟 沈兴家 沈中元 唐顺明 | 2022 | 蚕业科学2022，48，3： | 1 |

| 9 | Consensus of multi-agent systems with dynamic join characteristics under impulsive control显示文摘We study how to achieve the state consensus of a whole multi-agent system after adding some new agent groups dynamically in the original multi-agent system.We analyze the feasibility of dynamically adding agent groups under differen t forms of net work topologies that are currently common,and obtain four feasible schemes in theory,including one scheme that is the best in actual industrial production.Then,we carry out dynamic modeling of multi-agent systems for the best scheme.Impulsive control theory and Lyapunov stability theory are used to analyze the conditions so that the whole multi-agent system with dynamic join characteristics can achieve state consensus.Finally,we provide a numerical example to verify the practicality and validity of the theory. | Xiang HU Zufan ZHANG Chuandong LI | 2021 | Frontiers of Information Technology & Electronic Engineering2021，22，1： | 1 |

| 11 | The deep spatiotemporal network with dual-flow fusion for video-oriented facial expression recognition显示文摘The video-oriented facial expression recognition has always been an important issue in emotion perception.At present,the key challenge in most existing methods is how to effectively extract robust features to characterize facial appearance and geometry changes caused by facial motions.On this basis,the video in this paper is divided into multiple segments,each of which is simultaneously described by optical flow and facial landmark trajectory.To deeply delve the emotional information of these two representations,we propose a Deep Spatiotemporal Network with Dual-flow Fusion(defined as DSN-DF),which highlights the region and strength of expressions by spatiotemporal appearance features and the speed of change by spatiotemporal geometry features.Finally,experiments are implemented on CKþand MMI datasets to demonstrate the superiority of the proposed method. | Chenquan Gan Jinhui Yao Shuaiying Ma Zufan Zhang Lianxiang Zhu | 2023 | Digital Communications and Networks2023，9，6： | 0 |
| 12 | 家蚕追寄蝇孵化酶的基因克隆与特性分析显示文摘家蚕追寄蝇寄生于家蚕幼虫引起的蝇蛆病危害蚕业生产。为从分子水平研究家蚕追寄蝇的孵化机制,以发育1.5 d的蝇卵为材料,结合RACE技术获得家蚕追寄蝇孵化酶基因的全长cDNA,命名为EsHE(GenBank登录号:ON042475)。EsHE基因cDNA全长1 507 bp,包含159 bp 5′UTR、412 bp 3′UTR和936 bp的完整ORF,编码311个氨基酸;EsHE蛋白序列含有孵化酶特征序列HELMHVLGFMHE(锌结合基序)和YDYGSVMHY(Met-转角基序);系统进化树分析显示,家蚕追寄蝇与丝光绿蝇的孵化酶亲缘关系最近。qRT-PCR检测EsHE基因在家蚕追寄蝇卵期的表达模式,发现在卵产后36 h EsHE表达量开始大幅上升,至孵化前的48 h达到最高水平;且在3龄幼虫中肠组织高水平表达。这些结果暗示EsHE与家蚕追寄蝇的胚胎发育和孵化密切相关,还可能参与幼虫期的食物消化、蛋白质代谢等生物学过程。通过以家蚕追寄蝇基因组DNA为模板扩增发现,EsHE基因含有1个内含子(2 638 bp)和2个外显子(第1外显子1 005 bp,第2外显子502 bp),基因结构与铜绿蝇、丝光绿蝇HE相似。上述研究结果为进一步阐明家蚕追寄蝇孵化分子机理奠定了基础,为以孵化相关基因作为靶点的杀虫剂研究开发提供了理论基础。 | 王闪闪 浦月霞 Zufan Bekele Kassa 王耒耒 徐娇 刘吉银 王梅仙 朱娟 沈兴家 沈中元 唐顺明 | 2022 | 蚕业科学2022，48，5： | 0 |
| 13 | Beam interference suppression in multi-cell millimeter wave communications显示文摘Due to the increase in the number of users, beam switching is used for suppressing interference, which leads to higher computational complexity in multi-cell millimeter wave communications. In order to resolve this problem, a beam interference model is introduced, and a lower complexity beam interference suppression algorithm based on user grouping is proposed. The proposed algorithm operates beam switching and mnlti-cell cooperative transmission for a part of the users when there exists beam interference due to high user density. In particular, considering the distinct interference suffered by each user, the proposed dual-threshold user grouping method can effectively solve the frequent switching problem at the base station caused by multi-cell cooperative transmission in multi-cell environments. Simulation results show that the proposed algorithm can reduce the computational complexity of beam switching and approach ideal system capacity, compared with conventional interference suppression algorithms that do not involve grouping of users. | Zufan Zhang Honghui Yu | 2019 | Digital Communications and Networks2019，5，3： | 0 |
