| 1 | Energy-Optimal and Delay-Bounded Computation Offloading in Mobile Edge Computing with Heterogeneous Clouds显示文摘By Mobile Edge Computing(MEC), computation-intensive tasks are offloaded from mobile devices to cloud servers, and thus the energy consumption of mobile devices can be notably reduced. In this paper, we study task offloading in multi-user MEC systems with heterogeneous clouds, including edge clouds and remote clouds. Tasks are forwarded from mobile devices to edge clouds via wireless channels, and they can be further forwarded to remote clouds via the Internet. Our objective is to minimize the total energy consumption of multiple mobile devices, subject to bounded-delay requirements of tasks. Based on dynamic programming, we propose an algorithm that minimizes the energy consumption, by jointly allocating bandwidth and computational resources to mobile devices. The algorithm is of pseudo-polynomial complexity. To further reduce the complexity, we propose an approximation algorithm with energy discretization, and its total energy consumption is proved to be within a bounded gap from the optimum. Simulation results show that, nearly 82.7% energy of mobile devices can be saved by task offloading compared with mobile device execution. | Tianchu Zhao Sheng Zhou Linqi Song Zhiyuan Jiang Xueying Guo Zhisheng Niu | 2020 | China Communications2020,17,5: | 18 |
| 2 | Integrated resources planning in microgrids considering interruptible loads and shiftable loads显示文摘Demand response has the potential to bring significant benefits to the optimal sizing of distributed generation(DG) resources for microgrids planning. This paper presents an integrated resources planning model considering the impact of interruptible loads(ILs) and shiftable loads(SLs) in microgrids, which simultaneouslydeals with supply side and demand side resources and minimizes the overall planning cost of the microgrid. The proposed model can be applied to offer a quantitative assessment how IL and SL can contribute to microgrid planning. The pure peak clipping model with IL and SL is also provided for comparisons. Moreover, sensitivity analysis of parameters in the model is performed.Numerical results confirm that the proposed model is an effective method for reducing the planning cost of microgrids. It was also found that the major contributing factors of IL and SL have great impact on the economic benefits of the proposed model in low-carbon economy environments. | Lan ZHU Xueying ZHOU Xiao-Ping ZHANG Zheng YAN Shuxin GUO Longjun TANG | 2018 | Journal of Modern Power Systems and Clean Energy2018,6,4: | 11 |
| 3 | Structure regulated catalytic performance of gold nanocluster-MOF nanocomposites显示文摘Atomically precise gold(Au)nanoclusters(NCs)as visible light photosensitizers supported on the substrate for photoredox catalysis have attracted considerable attentions.However,eficient control of their photocatalytic activity and long-term stability is still challenging.Herein,we report a coordination-assisted self-assembly strategy in combination with electrostatic interaction to sandwich Au2:(Capt)18(abbreviated as AU25,Capt=captopril)NCs between an inner core and an outer shell made of UiO-66,denoted as UiO-66@Au25@UiO-66.Notably,the sandwich-like nanocomposite displays significantly enhanced catalytic activity along with an excellent stability when used in the selective photocatalytic aerobic oxidation of sulfide to sulfoxide.As comparison,AU25 NCs simply located at the outer surface or insider matrix of UiO-66(short as Au2/UiO-66 and AU2s@UiO-66)show poor stability and low conversion,respectively.This structure regulated difference in the catalytic performances of three nanocomposites is assigned to the varied distribution of active sites(Au NCs)in metal-organic frameworks(MOFs).This work offers the opportunity for application of nanoclusters in catalysis,energy conversion and even biology. | Yanfei Zhu Xueying Qiu Shenlong Zhao Jun Guo Xiaofei Zhang Wenshi Zhao Yanan Shi Zhiyong Tang | 2020 | Nano Research2020,13,7: | 7 |
| 4 | Cloning,expression and binding specificity analysis of odorant binding protein 3 of the lucerne plant bug,Adelphocoris lineolatus(Goeze)显示文摘Credible evidence shows that odorant binding proteins(OBPs)are required for insect olfaction perception and play a key role in transporting hydrophobic odorants across the sensillum lymph to the olfactory receptors(ORs).In the present study,a novel OBP(AlinOBP3)gene from the lucerne plant bug,Adelphocoris lineolatus,was cloned and expressed.The expression pattern of AlinOBP3 was evaluated by qPCR,which indicated that AlinOBP3 was dominantly expressed in antennae.The binding properties of AlinOBP3 with 9 cotton volatiles and 5 sex pheromone analogs were measured by fluorescence competitive binding assays with the fluorescence probe 1-NPN.The results revealed that of 9 cotton volatiles,Myrcene,β-Ocimene and α-Phellandrene can bind with AlinOBP3.α-Phellandrene especially bound to AlinOBP3 with a high binding affinity,with a dissociation constant of 56.68 μmol/L.Of the 5 sex pheromone analogs,Hexyl butyrate had the strongest binding affinity with AlinOBP3,with a dissociation constant as 59.53 μmol/L.Butyl butyrate,trans-2-Hexenyl butyrate and Ethyl butyrate had medium binding affinities with AlinOBP3,with dissociation constants of 227.39,108.77 and 143.47 μmol/L,respectively.The results suggest that AlinOBP3 might be a pheromone binding protein(PBP)with a dual-function for the perception of sex pheromones and plant volatiles. | GU ShaoHua SUN Yang REN LiYan ZHANG XueYing ZHANG YongJun WU KongMing GUO YuYuan | 2010 | Chinese Science Bulletin2010,55,34: | 7 |
| 5 | Magnetic polyamidoamine dendrimers for magnetic separation and sensitive determination of organochlorine pesticides from water samples by high-performance liquid chromatography显示文摘Organochlorine pesticides(OCPs)have received much attention due to their toxicity.Reliable methods to monitor their residues in the environment are needed.Here,magnetic polyamidoamine dendrimers were prepared by co-precipitation,Michael addition,and amidation.The magnetic polyamidoamine dendrimers demonstrated good adsorption ability for OCPs—this feature was utilized to construct a sensitive tool for monitoring OCPs in water samples.The proposed method provided remarkable linearity from 0.1 to 500μg/L and satisfactory limits of detection from 0.012 to 0.029μg/L.The spiked recoveries of the four target analytes were 91.8%-103.5%with relative standard deviations less than 4.5%.The magnetic materials had good reusability.The results indicated that the resulting method was an efficient,easy,rapid,economical,and eco-friendly tool for monitoring OCPs in aqueous samples. | Qingxiang Zhou Yalin Wu Yi Sun Xueying Sheng Yayan Tong Jinghan Guo Boyao Zhou Jingyi Zhao | 2021 | Journal of Environmental Sciences2021,33,4: | 5 |

| 7 | Associations of PGK1 promoter hypomethylation and PGK1-mediated PDHK1 phosphorylation with cancer stage and prognosis:a TCGA pan-cancer analysis显示文摘Background:Cancer cells reprogram metabolism for proliferation.Phosphoglycerate kinase 1(PGK1),as a glycolytic enzyme and newly identified protein kinase,coordinates glycolysis and mitochondrial metabolism.However,the clini-cal significance of PGK1 expression and function in cancer progression is unclear.Here,we investigated the relation-ship between the progression and prognosis of multiple cancer types and PGK1 expression and its function in the mitochondrial metabolism regulation.Methods:We performed pan-cancer analyses of PGK1 mRNA level and DNA methylation in 11,908 tumor tissues and 1582 paired normal tissues across 34 cancer types in The Cancer Genome Atlas datasets.Using specific antibodies against PGK1 S203 and PDHK1 T338 phosphorylation,we performed immunohistochemistry with tissue microarray assay in additional 818 cancer cases with 619 paired normal tissues from five cancer types.Results:The PGK1 mRNA level was significantly elevated with hypomethylation in promotor regions and associated with advanced TNM stage in 15 and four cancer types,respectively.In breast carcinoma,elevated PGK1 mRNA level and promoter hypomethylation were associated with poor prognosis.Positively correlated PGK1 S203 and PDHK1 T338 phosphorylation levels were significantly associated with short overall survival(OS)in cancers of the breast,liver,lung,stomach,and esophagus and with advanced TNM stage in breast and esophageal cancers.PGK1 pS203 and PDHK1 pT338 were also independent predictors of short OS in liver,lung,and stomach cancer.Conclusions:The elevated expression,promoter hypomethylation,and phosphorylation of PGK1 and PDHK1 were related with disease progression and short OS in diverse types of cancer.PGK1 and PDHK1 phosphorylation may be potential prognostic biomarkers. | Fei Shao Xueying Yang Wei Wang Juhong Wang Wei Guo Xiaoli Feng Susheng Shi Qi Xue Shugeng Gao Yibo Gao Zhimin Lu Jie He | 2019 | Cancer Communications2019,39,1: | 4 |
| 8 | Single-cell transcriptomic landscape of human blood cells显示文摘High throughput single-cell RNA-seq has been successfully implemented to dissect the cellular and molecular features underlying hematopoiesis.However,an elaborate and comprehensive transcriptome reference of the whole blood system is lacking.Here,we profiled the transcriptomes of 7551 human blood cells representing 32 immunophenotypic cell types,including hematopoietic stem cells,progenitors and mature blood cells derived from 21 healthy donors.With high sequencing depth and coverage,we constructed a single-cell transcriptional atlas of blood cells(ABC) on the basis of both protein-coding genes and long noncoding RNAs(lncRNAs),and showed a high consistence between them.Notably,putative lncRNAs and transcription factors regulating hematopoietic cell differentiation were identified.While common transcription factor regulatory networks were activated in neutrophils and monocytes,lymphoid cells dramatically changed their regulatory networks during differentiation.Furthermore,we showed a subset of nucleated erythrocytes actively expressing immune signals,suggesting the existence of erythroid precursors with immune functions.Finally,a web portal offering transcriptome browsing and blood cell type prediction has been established.Thus,our work provides a transcriptional map of human blood cells at single-cell resolution,thereby offering a comprehensive reference for the exploration of physiological and pathological hematopoiesis. | Xiaowei Xie Mengyao Liu Yawen Zhang Bingrui Wang Caiying Zhu Chenchen Wang Qing Li Yingying Huo Jiaojiao Guo Changlu Xu Linping Hu Aiming Pang Shihui Ma Una Wang Wenbin Cao Shulian Chen Qiuling Li Sudong Zhang Xueying Zhao Wen Zhou Hongbo Luo Guoguang Zheng Erlie Jiang Sizhou Feng Lixiang Chen Lihong Shi Hui Cheng Sha Hao Ping Zhu Tao Cheng | 2021 | National Science Review2021,8,3: | 3 |
| 9 | REE Geochemistry of VMS and SEDEX Ores in China显示文摘REE ratios and patterns for massive pyrite ore and massive cuprous pyrite ore ofthe Baiyinchang orefield are quite similar to those for quartz keratophyritic tuff and quartzalbitophyre of the same orefield. However, massive cuprous pyrite ore of the Ashele Cu-Zn de-posit is similar to basalt-diabase of the same district in REE geochemistry. Comparison of theChinese VMS ores with those from Rio Tinto, Spain and Que River, Australia, in REEgeochemistry has been made. REE ratios and patterns of bedded-massive and massive ores ofthe Changba-Lijiagou Zn-Pb deposit, the second largest SEDEX deposit in China are similarto those of their host rocks, the Qinling shales of Devonian age and the Changba adamellite.The three types of ore and their host rocks of the Dongshengmiao pyrite (pyrrhotite)-Zn-Pbdeposit have parallel REE ratios and patterns. | Song Xuexin Xu Qingsheng Guo Yuemin Mao Xueying and Ouyang Hong Institute of Mineral Deposits, Chinese Academy of Geological Sciences, Beijing Institute of High Energy Physics, Chinese Academy of Sinices, Beijing | 1997 | Acta Geologica Sinica(English Edition)1997,71,3: | 3 |
| 10 | Frequent RNF43 mutation contributes to moderate activation of Wnt signaling in colorectal signet-ring cell carcinoma显示文摘Dear Editor,Signet-ring cell carcinoma(SRCC)is a rare subtype of colorectal cancer(CRC)characterized histologically by the accumulation of mucins in the cytoplasm and displacement of nuclei to the cellular periphery,accounting for about 1%CRC(Fig.S1A)(Borger et al.,2007).Compare to common subtypes of CRC,such as adenocarcinoma(AC)and mucinous adenocarcinoma(MAC),SRCC is associated with aggressive behaviors and younger age at presentation(Kang et al.,2005;Sung et al.,2008;Nitsche et al.,2013;Hugen et al.,2014;Inamura et al.,2015).A retrospective analysis of CRC patient's data at Fudan University Shanghai Cancer Center(FUSCC)also indicated a worse overall and disease-free survival of SRCC patients(Fig.S1B and S1C,Table S1). | Yaqi Li Jian Li Renjie Wang Long Zhang Guoxiang Fu Xueying Wang Yebin Wang Chuantao Fang Dandan Zhang Duo Du Xiaoji Ma Mengxue Pan Qiang Guo Xiaoya Xu Xiang Hu Yi Zhou Shaobo Mo Huijun Wang Jianjun Gao Shenglin Huang Yun Liu Sanjun Cai Guoqiang Hua Junjie Peng Fa-Xing Yu | 2020 | Protein & Cell2020,11,4: | 2 |

| 14 | Optical Activity of Chiral Metal Nanoclusters显示文摘CONSPECTUS:The emerging chirality in nanomaterials represents one of the most dynamic areas in modern science.Although many novel chiral nanomaterials have been reported,the origin of their chirality and related optical activity have been not unveiled unambiguously.Thanks to the fast development of noble metal cluster chemistry,the structures of many chiral nanoclusters(CNCs)have been precisely determined and their chirality origin has been decoded as four different levels including chiral ligand,helix staple motif,asymmetry metal kernel,and chiral arrangement of organic ligands.Generally,the strong optical activity associated with the electron transitions of the noble metal core is popularly reported among CNCs protected by chiral ligands,following the so-called“outside-in”chirality transfer theory,namely,from organic ligand to metal core.Exceptionally,inherent chiral structures are discerned inside CNCs consisting of achiral ligands,such as the helix staples found in Au38(SR)24 and Au102(SR)44(SR=thiolate)and the chiral metal kernel existing in Au20(PP3)4Cl4(PP3=tris(2-(diphenylphosphino)ethyl)phosphine).These chiral nanostructures induce distinct optical activity and even present reversed chirality transformation in the case of Au38(SR)24(i.e.,from chiral core structure to organic ligand).In the past decade,our group has carried out extensive research work on preparation,enantioseparation,optical activity,and application of chiral inorganic nanostructures.As representatives,enantiopure right-handed and left-handed Au20(PP3)4Cl4 clusters of intrinsic kernel chirality were acquired through an innovative supramolecular self-assembly method and their circular dichroism(CD)feature involving only the metal core was systematically studied;Au3[R/S-Tol-BINAP]3Cl(R/S-Tol-BINAP:R/S-2,2′-bis(di-p-tolylphosphino)-1,1′-binaphthyl)clusters with the smallest metal-atom number among the reported CNCs were designed and synthesized by using the privileged chiral Tol-BINAP ligand,which exhibited not only strongly enhanced CD signal also remarkable circular polarized luminescence(CPL)response as selfassembled into monodispersed nanocubes.In this Account,we aim at reviewing the fast development of CNCs featuring strong chiral attributes and optical activity.We will briefly introduce the preparation methods of CNCs,such as direct synthesis,ligand exchange,and enantioseparation.In the following parts,the commonly used tools for characterizing the chirality of CNCs are summarized,including CD,vibrational circular dichroism(VCD),CPL,single X-ray diffraction,nuclear magnetic resonance(NMR),and theoretical prediction.Then,the optical activity of CNCs will be systematically discussed,especially their CD,VCD,and CPL activity along with their chirality origin.Finally,future strategies for fabricating CNCs possessing strong optical activity as well as potential chirality-related applications will be proposed.We believe that this Account will trigger more research interest to not only study the amazing optical activity of CNCs but also employ them in many fields. | Yanfei Zhu Jun Guo Xueying Qiu Shenlong Zhao Zhiyong Tang | 2021 | Accounts of Materials Research2021,2,1: | 1 |

| 16 | Pasteurella multocida capsular:lipopolysaccharide types D:L6 and A:L3 remain to be the main epidemic genotypes of pigs in China显示文摘Pasteurella multocida is a leading cause of respiratory disorders in pigs.This study was designed to understand the genotypical and antimicrobial resistant characteristics of P.multocida from pigs in China.To achieve this,we briefly investigated 158 P.multocida isolates from pigs with respiratory disorders in China between 2019 and 2020.Genotyping through multiplex PCR assays assigned these 158 isolates into capsular genotypes A(60.13%,95/158),D(35.44%,56/158),F(4.43%,7/158),and/or lipopolysaccharide(LPS)genotypes L3(28.48%,45/158)and L6(66.46%,105/158).In addition,eight isolates(5.06%,8/158)were found to be nontypable using the LPS genotyping method.When combining the capsular genotypes and the LPS genotypes,D:L6(34.81%,55/158)and A:L6(31.65%,50/158)were the predominant genotypes,followed by A:L3(24.05%,38/158).PCR detection of virulence factor-encoding genes showed that over 80%of the isolates were positive for exbB,tonB,exbD,ompH,ptfA,fimA,sodA,sodC,fur,ompA,oma87,plpB,hsf-2,nanH and hgbB,suggesting the presence of these genes were broad characteristics of P.multocida.We also found approximately 63.92%(101/158),51.27%(81/158),8.86%(14/158),7.59%(12/158),3.16%(5/158),0.63%(1/158),and 0.63%(1/158)of the isolates grew well in media with the presence of colistin(4μg/mL),tetracycline(16μg/mL),tigecycline(1μg/mL),ampicillin(32μg/mL),chloramphenicol(32μg/mL),cefepime(16μg/mL),and ciprofloxacin(1μg/mL),respectively.This study contributes to the understanding of genotypes and antimicrobial resistance profile of P.multocida currently circulation in pigs of China. | Songtao Liu Lin Lin Hao Yang Wenqing Wu Long Guo Yue Zhang Fei Wang Xueying Wang Wenbo Song Lin Hua Wan Liang Xibiao Tang Huanchun Chen Zhong Peng Bin Wu | 2021 | Animal Diseases2021,1,4: | 1 |

| 18 | Single site catalyst with enzyme-mimic micro-environment for electroreduction of CO_(2)显示文摘Single site catalysts provide a unique platform for mimicking natural enzyme due to their tunable interaction between metal center and coordinated ligand.However,most works have focused on preparing structural and functional models of nature enzyme,with less reports also taking the local chemical environment,i.e.,functional/catalytic residues around the active site which is an essential feature of enzymes,into consideration.Herein,we report a Co-centered porphyrinic polymer containing the enzyme-mimic micro-environment,where the linker triazole over CoN4 site enables formation of hydrogen bond with the*COOH intermediate,thus promoting the electrocatalytic reduction of CO_(2).As-prepared catalyst achieves the CO_(2)-to-CO conversion of 5,788 h^(−1) turnover frequency value and near unit(~96%)faradaic efficiency at−0.61 V versus reversible hydrogen electrode.This strategy will bring new dimension of designing highly active single-site catalysts. | Chang Long Kaiwei Wan Xueying Qiu Xiaofei Zhang Jianyu Han Pengfei An Zhongjie Yang Xiang Li Jun Guo Xinghua Shi Hui Wang Zhiyong Tang Shaoqin Liu | 2022 | Nano Research2022,15,3: | 1 |
| 19 | The interventional effect of Polygonatum cyrtonema Hua polysaccharide on atherosclerosis in mice of different sexes显示文摘In the present study,we investigated the intervention effects of a purified Polygonatum cyrtonema polysaccharide(PCP)on high-fat diet(HFD)-induced atherosclerosis in male and female LDLr-/-mice.Results showed that HFD caused severe dyslipidemia,atherosclerotic lesions,oxidative damages and inflammation in male and female mice,and these effects seemed to be more pronounced in males than in females.However,the above variations could be dose-dependently reversed by PCP treatment,and the intervention effects on males were greater than those on females.Nuclear factor kappa-B(NF-κB),mitogen-activated protein kinase(MAPKs)and protein kinase B(Akt)are 3 pivotal signaling pathways mediating the development of atherosclerosis.Consistently,PCP was also found to significantly decrease the phosphorylation of p65,p38,extracellular-regulated kinase 1/2(ERK1/2)and Akt,and increase the protein expression of inhibitor of NF-κB(IκB)in the aortas of male and female mice induced by HFD.Taken together,these findings indicated that PCP could be effective for the prevention of atherosclerosis,and the intervention effect of PCP on male mice was more obvious than that of female mice. | Anjun Guo Xueying Li Lihua Pan Qiangming Li Jianping Luo Xueqiang Zha | 2024 | Food Science and Human Wellness2024,13,1: | 0 |
