1Cloning and Characterization of miRNAs and Their Targets, Including a Novel miRNA-Targeted NBS-LRR Protein Class Gene in Apple (Golden Delicious)显示文摘MicroRNA (miRNA ) 在植物作为基因表示的一个重要管理者出现了。146 miRNAs 从苹果被识别(Malus domestica cv。金色美味) 由定序的生物信息的分析和 RNA 图书馆。从这些, 135 被保存, 11 是新奇 miRNAs。目标分析预言了新奇 miRNAs 之一, Md-miRLn11 (Malus domestica microRNA Ln11 ) ,指向了一个苹果核苷酸绑定地点(NBS ) 充满白氨酸的重复(LRR ) 班蛋白质编码基因(Md-NBS ) 。5 赛跑试金证实了 Md-miRLn11 的能力在 1112-nt 位置劈开 Md-NBS。Md-miRLn11 和 Md-NBS 的表示的分析在在 40 个苹果变化的最佳侵略时期期间证明在抵抗变化的 Md-NBS 基因的表示比在易受影响的变化高,与为 Md-miRLn11 的一个反的模式。从抵抗苹果变化 JiGuan 的幼苗被用来执行 Agrobacterium 渗入试金,然后与苹果叶点疾病接种。结果在 JiGuan 苹果显示出疾病抵抗的清楚的衰落。相反,与 Md-NBS 基因渗入的易受影响的变化富士在疾病抵抗显示出重要增加。基于上述结果,我们建议 Md-miRLn11 特别地在病原体感染的条件下面调整 Md-NBS 基因表示,并且指向 P 环地点的 Md-miRLn11 可以在木质的植物调整许多 NBSLRR 蛋白质类基因。Chao Ma You Lu Songlin Bai Wennan Zhang Xuwei Duan Dong Meng Zhigang Wang Aide Wang Zongshan Zhou Tianzhong Li 2014Molecular Plant2014,7,1:19
21997年全国艾滋病哨点监测报告显示文摘1997年,全国HIV监测哨点共调整为60个,分布在27个省(自治区、直辖市)。性病门诊哨点和长卡哨点中只检出极少数HIV感染者。1997年,在3个暗娼哨点中的检出率约为1%~2%,而1996年同期仅为不到0.5%;在12个吸毒哨点中有7个哨点(包括2个新增哨点)报告了HIV感染者,而在1996年同期8个哨点中有3个哨点报告了感染者。新疆自治区报告了83例(20.8%)感染者,而在前几年同期同一哨点只有32例(8.0%)。在大部分吸毒监测哨点中的静注比例正不断增加或保持一个较高水平。暗娼人群中有60%从不使用避孕套。该监测结果表明,局部地区吸毒者中HIV感染率在不断上升,HIV波及的地区在不断地增多,HIV感染已开始向性乱人群扩散;可引起HIV流行的危险因素在不断增加。Department of Disease Control,Ministry of Health,People′s Republic of China 1 Center for AIDS Surveillance,Chinese Academy of Preventive Medicine 2 Group of National HIV Sentinel Surveillance Program (Written by Qu Shuquan 2,Sun Xinhua 1,Zheng X 1998中国性病艾滋病防治1998,4,4:15
31996年中国艾滋病哨点监测报告显示文摘我国自1995年开始在23个省(自治区、直辖市)的42个哨点中对性传播疾病(STDs)门诊就诊者、暗娼、吸毒者和长途卡车司机四类人群进行监测,当年监测结果显示,在监测哨点所在的城市中,被监测的STDs门诊就诊者、暗娼、吸毒者和长途卡车司机人群中HIV感染率均很低,但存在广泛传播的危险性。1996年第一轮共监测10085人,发现HIV感染者35例。其中在STDs门诊就诊者中发现HIV感染者1例,在吸毒者中发现HIV感染者34例(其中新疆32例);第二轮监测11909人,发现HIV感染者72例,其中在暗娼人群中发现1例,在吸毒人群中发现71例(其中新疆69例)。1996年监测结果表明,在哨点所在的城市中,尽管被监测的STDs门诊就诊者、暗娼和长途卡车司机人群中HIV感染率仍很低,但我国HIV流行形势已发生改变,HIV感染的流行已不仅仅局限于云南吸毒者中,在其它地区已开始在吸毒者中流行,个别地区该人群中HIV感染率上升很快。Department of Disease control.Ministry of Health,People′s Republic of China 1 Center for AIDS Surveillance,Chinese Academy of Preventive Medicine 2 Group of National HIV sentinel surveillance program (Written by Qu Shuquan 2,Sun Xinhua 1,Zheng Xiwen 1997中国性病艾滋病防治1997,3,5:12
4Comparative Transcriptome Analysis of Actinidia arguta Fruits Reveals the Involvement of Various Transcription Factors in Ripening显示文摘The fruit of Actinidia arguta is typically climacteric.During ripening,the fruits produce a large amount of ethylene.Although the molecular basis of climacteric fruit ripening has been extensively studied,some aspects such as its transcriptional regulation remain unclear.Here,we compared the transcriptomes of A.arguta fruits collected at commercial harvest(sample d0)and at 6 days after harvest(sample d6)using RNA-seq.A total of 3 659 differentially expressed genes(DEGs)between samples d0 and d6 were detected,of which 2 983 and 1 104 could be functionally annotated with Gene Ontology(GO)and Clusters of Orthologous Groups(COG)pathways.DEGs involved in ethylene biosynthesis and signal transduction were identified,including ACO(c79627),ERF061(c105131),and ERF6(c99193).Transcription factors such as ERF,b HLH,NAC,MADS,and MYB were also differentially expressed between samples d0 and d6.Selected DEGs were subjected to further analysis using quantitative reverse transcription-polymerase chain reaction(q RT-PCR),and the results coincided with those of RNA-seq.Our data revealed additional transcription factors that are involved in the regulation of fruit ripening.These results provide useful information for future research on the transcriptional regulation of fruit ripening.HUANG Guohui QU Yi LI Tong YUAN Hui WANG Aide TAN Dongmei 2018Horticultural Plant Journal2018,4,1:9
5Characteristics of the lower layer of sandstorms in the Minqin desert-oasis zone显示文摘By measuring the sand-dust flux,vertical deposition,and the wind velocity throughout 19 sandstorms in the Minqin region,we quantitatively analyzed the horizontal distribution and vertical variation in sandstorm characteristics under different land cover conditions.The effect of different land cover on mitigating sandstorms was also investigated.The results indicated that,in the surface layer ranging from 0-50 m,the intensity of sand-dust horizontal flux and concentration of sand-dust decreased with the increase of the height in the desert and the edge of oasis,whereas the two physical quantities increased slightly with the increase of the height in the oasis.The two physical quantities obey power function well under all three cover conditions.Moreover,in the desert and at the edge of oasis,the sand-dust vertical deposition decreased with the increase of the height.But a partial unimodal distribution at the oasis site and the maximum deposition occurred at the height of 9 m,which corresponds to the middle height of farmland protection forest.The annual flux that passed through a section of 1 m in width and 50 m in height was 9169 kg in the desert,5318 kg at the edge of oasis,and 2345 kg in the oasis.And the annual fluxes at the edge of oasis and in the oasis are 42% and 74% less,respectively,than that in the desert.This implies that the wind break forest significantly reduced the intensity of sandstorms.ZHAO Ming ZHAN KeJie YANG ZiHui FANG ErTian QIU GuoYu WANG QiangQiang ZHANG YinChang GUO ShuJiang LI AiDe ZHANG JingChun 2011Science China Earth Sciences2011,54,5:8

7波多黎各的城市扩张和基本农业用地的丧失显示文摘在许多由农业经济转变为工业经济的国家,废弃的农业用地由于城市化而消失。约4个多世纪的时间,波多黎各的经济几乎完全依靠农业,但20世纪初的社会政治变化导致了它的经济向工业经济转变。经济的变化和人口的增加使得城市面积扩大。本文分析了1977~1994年波多黎各城市增长率和城市扩大的分布,以及它们对潜在的农地产生的影响。城市的范围和扩大部分是通过解译航空像片和卫星像片得到的。在潜在农业用地的基础上,把1994年拍摄的城市范围和土地范围结合在一起,得出了相对于潜在农地面积的城市面积分布。分析表明,1977年波多黎各面积的11.3%为城市。17年后,城市面积扩大了27.4%,在农业适宜地上,城市面积的增长量为41.6%。这意味着丧失了6%的潜在农地。如果城市增长蚕食潜在农地的情况继续下去,波多黎各未来的粮食生产将受到极大的限制。Tania del Mar López T.Mitchell Aide John R.Thomlinson 高启晨 2001AMBIO-人类环境杂志2001,30,1:5
8基于信道状态信息的人体行为识别系统显示文摘提出了一种基于无设备的人体行为识别系统,利用Wi-Fi信号的信道状态信息(CSI)来识别3个动态活动:行走、摔倒和坐。该系统只需要一台Wi-Fi路由器作为发射器和一台装有无线网卡的笔记本电脑作为接收器。系统从WiFi信号中提取CSI,然后经过低通滤波以消除噪声,并且为了降低CSI的维度和避免周围噪声所带来的不良影响,在整个CSI数据流中采用了主成分分析(PCA)算法。因此,该系统能够从CSI的时域和频域中得到有用的信号特征值。继而,采用支持向量机(SVM)算法来对人体行为进行分类。为了评优系统的可用性和稳定性,跟5个用户在动态环境中,分别在视距(LOS)和非视距(NLOS)的条件下做了大量的实验,这些实验表明该系统能够得到较高的准确率。Mohammed Abdulaziz Aide Al-qaness 李方敏 马小林 梅华锋 2016武汉理工大学学报2016,38,4:4
9GPU-based dynamic quad stream for forest rendering显示文摘Rendering large-scale forest scenes in real-time is a challenging problem, since the geometric complexity is far beyond the capabilities of current graphics hardware. In this paper, we propose a novel approach that adopts a dynamic quad stream residing on GPU buffers for view-dependent forest rendering. The incremental quad stream updating process is well-suited to the massively parallel architecture of the GPU pipeline, and it requires no continuous data exchange between CPU and GPU. The implementation of the algorithm is quite straightforward. Despite its simplicity, the algorithm achieves good performance with low memory, storage, and CPU costs.LIU Feng, HUA Wei & BAO HuJun State Key Lab of Computer Aided Design and Computer Graphics, Zhejiang University, Hangzhou 310058, China 2010Science China(Information Sciences)2010,53,8:4

12LiFePO_4/C via fluoride doping显示文摘Non-stoichiometric compound fluoride-doped LiFePO4/C cathode materials were synthesized via solid-state reaction using MgF2 and AlF3 as dopant. The fluoride-doped LiFePO4/C samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and electrochemical testing. The results show that the materials are well crystallized and fluoride doping cannot change the space structure of LiFePO4. Slight amounts of Fe2O3 with no fluoride impurity were detected. Charge-discharge curves show that fluoride-doped samples have higher capacity at low rates compared with undoped LiFePO4/C. AlF3-doped samples have highest capacity at high discharge current. Both doped samples have larger polarization voltage than undoped samples. All samples exhibit good cycle stability.Gu Yuan Zhang Xiangjun Lu Shigang Zhao Ting Jiang Danping Yang Rong Wu Aide 2012Rare Metals2012,31,6:2
