| 1 | A DC Grid Benchmark Model for Studies of Interconnection of Power Systems显示文摘Reducing carbon emissions in the power sector is critical for transitioning to a sustainable and low-carbon future.Estimating carbon efficiency of demand side response(DSR)in the power system is an important step towards realizing potential environmental benefits.Marginal emission factor(MEF)is an effective tool for estimating incremental changes in carbon emissions as a result of a change in demand.However,estimation methods currently used for evaluating MEF can be improved upon,specifically,by factoring in the ramp-rate constraint of generators in the fuel cost based merit order dispatch.In this paper is described a new method for MEF assessment under ramp-rate constraints;the method is then compared with two conventional estimations in a British power system.Three fuel price scenarios are used to conduct a sensitivity analysis of MEFs to fuel prices.Conclusions are drawn that can pave the way for future improvements in estimating MEF in power systems. | Ting An Xiaoxin Zhou Congda Han Yanan Wu Zhiyuan He Hui Pang Guangfu Tang | 2015 | CSEE Journal of Power and Energy Systems2015，1，4： | 17 |
| 2 | Stress Corrosion Cracking of Nitrogen-containing Stainless Steel 316LN in High Temperature Water Environments显示文摘Stress corrosion cracking(SCC) of stainless steels and Ni-based alloys in high temperature water coolant is one of the key problems affecting the safe operation of nuclear power plants(NPPs).The nitrogen-added stainless steel is a kind of possible candidate materials for mitigating SCC since reducing the carbon content and adding nitrogen to offset the loss in strength caused by the decrease in carbon content can mitigate the problem of sensitization.However,the reports of SCC of nitrogen-added stainless steels in high temperature water are few available.The effects of applied potential and sensitization treatment on the SCC of a newly developed nitrogen-containing stainless steel(SS) 316LN in high temperature water doped with chloride at 250 ℃ were studied by using slow strain rate tests(SSRTs).The SSRT results are compared with our data previously published for 316 SS without nitrogen and 304NG SS with nitrogen,and the possible mechanism affecting the SCC behaviors of the studied steels is also discussed based on SSRT and microstucture analysis results.The susceptibility to cracking of 316LN SS normally increases with increasing potential.The susceptibility to SCC of 316LN SS was less than that of 316 SS and 304NG SS.Sensitization treatment at 700 ℃ for 30 h showed little effect on the SCC of 316LN SS and significant effect on the SCC of 316 SS.The predominant cracking mode for the 316LN SS in both annealed state and the state after the sensitization treatment was transgranular.The presented conditions of mitigating stress corrosion cracking are some useful information for the safe use of 316LN SS in NPPs. | YANG Wu LI Guangfu HUANG Chunbo ZHOU Jianjiang LU Zhanpeng | 2010 | Chinese Journal of Mechanical Engineering2010，23，6： | 9 |
| 3 | Delay Depending Decentralized Adaptive Attitude Synchronization Tracking Control of Spacecraft Formation显示文摘This paper deals with the problem of cooperative attitude tracking with time-varying communication delays as well as the delays between inter-synchronization control parts and self-tracking control parts in the spacecraft formation flying. First, we present the attitude synchronization tracking control algorithms and analyze the sufficient delay-dependent stability condition with the choice of a Lyapunov function when the angular velocity can be measured. More specifically, a class of linear filters is developed to derive an output feedback control law without having direct information of the angular velocity, which is significant for practical applications with low-cost configurations of spacecraft. Using a well-chosen Lyapunov-Krasovskii function, it is proven that the presented control law can make the spacecraft formation attitude tracking system synchronous and achieve exponential stability, in the face of model uncertainties, as well as non-uniform time-varying delays in communication links and different control parts. Finally, simulation results are presented to demonstrate the effectiveness of the proposed control schemes. | ZHOU Jiakang MA Guangfu HU Qinglei | 2012 | Chinese Journal of Aeronautics2012，25，3： | 8 |
| 4 | A 5'-flanking region polymorphism in toll-like receptor 4 is associated with gastric cancer in a Chinese population显示文摘Objective:Inflammation induced by H.pylori colonization in the stomach is related to the development of gastric cancer and the genetic variations of the genes involved in the immune responses modify the host response to the infection. The aim of this study was to evaluate whether polymorphisms in the toll-like receptor 4 (TLR4) gene, a key regulator of both innate and adaptive immunity, were related to the susceptibility togastric cancer in a Chinese population. Methods: Two variations in the 5'-flanking region of TLR4 (rs1927914 T>C and rs10759932 T>C) were genotyped by using the PCR-restriction fragment length polymorphism (RFLP) assay in a case-control study of 1,053 incident gastric cancer cases and 1,100 cancer-free controls in a Chinese population. Results: Individuals carrying the C allele of rs10759932 had a significantly reduced risk of gastric cancer (adjusted OR=0.81; 95%CI=0.67-0.96), compared with the wild-type homozygote (TT), and the protective effect was not significantly different among subgroups stratified by age, sex, smoking, drinking and H.pylori infection status (P for heterogeneity >0.05). No significant association was observed between rs1927914 and gastric cancer risk in this study population. Conclusion: The T to C allele substitution of rs10759932 may play a protective role in gastric carcinogenesis in a Chinese population. Large studies with different ethnic populations are warranted to confirm these findings. | Hua Huang Juan Wu Guangfu Jin Hanze Zhang Yanbing Ding Zhaolai Hua Yan Zhou Yan Xue Yan Lu Zhibin Hu Yaochu Xu Hongbing Shen | 2010 | The Journal of Biomedical Research2010，24，2： | 5 |
| 5 | First experimental constraints on WIMP couplings in the effective field theory framework from CDEX显示文摘We present weakly interacting massive particles(WIMPs) search results performed using two approaches of effective field theory from the China Dark Matter Experiment(CDEX), based on the data from both CDEX-1B and CDEX-10 stages. In the nonrelativistic effective field theory approach, both time-integrated and annual modulation analyses were used to set new limits for the coupling of WIMP-nucleon effective operators at 90% confidence level(C.L.) and improve over the current bounds in the low mχregion. In the chiral effective field theory approach, data from CDEX-10 were used to set an upper limit on WIMP-pion coupling at 90% C.L. We for the first time extended the limit to the m_(χ)<6 GeV/c^(2) region. | Yi Wang Zhi Zeng Qian Yue LiTao Yang KeJun Kang YuanJing Li Mehment Agartioglu HaiPeng An JianPing Chang JingHan Chen YunHua Chen JianPing Cheng Cheng Yi Chiang WenHan Dai Zhi Deng ChangHao Fang XinPing Geng Hui Gong QiuJu Guo XuYuan Guo HongJian He Li He ShengMing He JinWei Hu TuChen Huang HanXiong Huang HaiTao Jia LiPing Jia Xi Jiang HauBin Li JianMin Li Jin Li MingXuan Li RenMingJie Li Xia Li YuLan Li Bin Liao FongKay Lin ShinTed Lin ShuKui Liu YanDong Liu Yu Liu YuanYuan Liu ZhongZhi Liu Hao Ma YuCai Mao QiYuan Nie JinHua Ning Hui Pan NingChun Qi Jie Ren XiChao Ruan ChangSong Shang Vivek Sharma Ze She Lakhwinder Singh Monoj Kumar Singh TianXi Sun ChangJian Tang WeiYou Tang Yang Tian GuangFu Wang Li Wang Qing Wang Yu Chen Wang YunXiang Wang Zhen Wang Henry Tsz-King Wong ShiYong Wu YuCheng Wu HaoYang Xing Yin Xu Tao Xue YuLu Yan Nan Yi ChunXu Yu HaiJun Yu JianFeng Yue Ming Zeng BingTao Zhang Lei Zhang FengShou Zhang ZhenYu Zhang KangKang Zhao MingGang Zhao JiFang Zhou ZuYing Zhou JingJun Zhu | 2021 | Science China(Physics,Mechanics & Astronomy)2021，64，8： | 3 |
| 6 | Magnetism in Carbon Nanoscrolls: Quasi-Half-Metals and Half-Metals in Pristine Hydrocarbons显示文摘A magnetic ground state is revealed for the first time in zigzag-edged carbon nanoscrolls(ZCNSs)from spin-unrestricted density functional theory calculations.Unlike their flat counterpart-zigzag-edged carbon nanoribbons,which are semiconductors with spin-degenerate electronic structure-ZCNSs show a variety of magnetic configurations,namely spin-selective semiconductors,metals,semimetals,quasi-half-metals,and half-metals.To the best of our knowledge,this is the first discovery of quasi-half-metals and half-metals in a pure hydrocarbon without resort to an external electric field.In addition,we calculated the spin-dependent transportation of the semiconducting ZCNSs with 12 and 20 zigzag chains,and found that they are 13% and 17% at the Fermi level,respectively,suggesting that ZCNS can be an effective spin filter. | Lin Lai Jing Lu Lu Wang Guangfu Luo Jing Zhou Rui Qin Yu Chen Hong Li Zhengxiang Gao Guangping Li Wai Ning Mei Yutaka Maeda Takeshi Akasaka and Stefano Sanvito | 2009 | Nano Research2009，2，11： | 3 |
| 7 | Association of assisted reproductive technology, germline de novo mutations and congenital heart defects in a prospective birth cohort study显示文摘Emerging evidence suggests that children conceived through assisted reproductive technology(ART)have a higher risk of congenital heart defects(CHDs)even when there is no family history.De novo mutation(DNM)is a well-known cause of sporadic congenital diseases;however,whether ART procedures increase the number of germline DNM(gDNM)has not yet been well studied.Here,we performed whole-genome sequencing of 1137 individuals from 160 families conceived through ART and 205 families conceived spontaneously.Children conceived via ART carried 4.59 more gDNMs than children conceived spontaneously,including 332 paternal and 1.26 maternal DNMs,after correcting for parental age at conception,cigarette smoking,alcohol drinking,and exercise behaviors.Paternal DNMs in offspring conceived via ART are characterized by C>T substitutions at CpG sites,which potentially affect protein-coding genes and are significantly associated with the increased risk of CHD.In addition,the accumulation of non-coding functional mutations was independently associated with CHD and 87.9% of the mutations were originated from the father.Among ART offspring,infertility of the father was associated with elevated paternal DNMs;usage of both recombinant and urinary follicle-stimulating hormone and high-dosage human chorionic gonadotropin trigger was associated with an increase of maternal DNMs.In sum,the increased gDNMs in offspring conceived by ART were primarily originated from fathers,indicating that ART itself may not be a major reason for the accumulation of gDNMs.Our findings emphasize the importance of evaluating the germline status of the fathers in families with the use of ART. | Cheng Wang Hong Lv Xiufeng Ling Hong Li Feiyang Diao Juncheng Dai Jiangbo Du Ting Chen Qi Xi Yang Zhao Kun Zhou Bo Xu Xiumei Han Xiaoyu Liu Meijuan Peng Congcong Chen Shiyao Tao Lei Huang Cong Liu Mingyang Wen Yangqian Jiang Tao Jiang Chuncheng Lu Wei Wu Di Wu Minjian Chen Yuan Lin Xuejiang Guo Ran Huo Jiayin Liu Hongxia Ma Guangfu Jin Yankai Xia Jiahao Sha Hongbing Shen Zhibin Hu | 2021 | Cell Research2021，31，8： | 2 |
| 8 | Sedimentary Facies, Provenance and Geochronology of the Heshangzhen Group: Implications for the Tectonic Evolution of the Eastern Jiangnan Orogen, South China显示文摘The Neoproterozoic Jiangnan orogen plays an important role in the study of the Precambrian tectonic evolution of South China. The tectonic nature of the Neoproterozoic sedimentary basins is still controversial, due to poor understanding of the sedimentary sequences and the lack of geochronological data. Here, we present sedimentological, provenance and geochronological data from the Heshangzhen Group in the eastern Jiangnan orogen. Sedimentological analysis shows that the Luojiamen Formation was deposited in a submarine fan, and the overlying Hongchicun Formation was deposited in front of a fan delta. The youngest detrital zircons constrain the lower Luojiamen and Hongchicun formations with ages of 827.3 ± 8.4 Ma and 825 ± 12 Ma, respectively. The sandstones of the Luojiamen Formation are characterized by a large number of intermediate to felsic volcanic grains, suggesting a volcanic arc source. In contrast, quartz and sedimentary lithic grains increase in the Hongchicun Formation, showing a new input from a collisional orogenic source. Detrital zircon from six sandstone samples in the Luojiamen and Hongchicun formations yield similar age spectra of 930–820 Ma with a peak at ca. 845–860 Ma, with one main cluster at 930–820 Ma. Detrital zircons of 930–845 Ma show a positive value of εHf(t)(+2.4 to +11, mean +7.6), which is similar to the volcanic arc of the nearby Shuangxiwu Group. There are a minor group of zircons with U-Pb ages ranging from 820 Ma to 845 Ma from the middle part of the Luojiamen Formation and Hongchicun Formation, with εHf(t) values between-20 to +2.4, which are consistent with the characteristics of the Shuangqiaoshan Group. within light of the bidirectional paleocurrents in the Luojiamen Formation, it is speculated that the zircons of 820–845 Ma were recycled from the Shuangqiaoshan Group, which is derived from a continental arc to the northwest. Our data suggests that the Luojiamen Formation was formed in an inter-arc basin, while the Hongchicun Formation was formed in an accretionary wedge-top basin. When juxtaposed with the conglomeratic characteristics at the bottom of the Luojiamen Formation, it is believed that the unconformity represented by the ‘Shen Gong Movement' reflects the rapid erosion and accumulation process of island arc volcanic material. The disconformity between the Luojiamen and Hongchicun formations is the imprint of transition from inter-arc basin to accretionary wedge-top basin,which represents the collision between the Shuangxiwu arc and the Yangtze Plate. | ZHOU Xiaohua HU Xiumian JIANG Ren GAO Tianshan MA Xue XING Guangfu SUN Gaoyuan SHU Xujie ZHAO Xilin | 2020 | Acta Geologica Sinica(English Edition)2020，94，4： | 2 |

| 10 | Energy-Efficient Power Allocation for IoT Devices in CR-NOMA Networks显示文摘Non-orthogonal multiple access is a promising technique to meet the harsh requirements for the internet of things devices in cognitive radio networks.To improve the energy efficiency(EE)of the unlicensed secondary users(SU),a power allocation(PA)algorithm with polynomial complexity is investigated.We first establish the feasible range of power consumption ratio using Karush-Kuhn-Tucker optimality conditions to support each SU’s minimum quality of service and the effectiveness of successive interference cancellation.Then,we formulate the EE optimization problem considering the total transmit power requirements which leads to a non-convex fractional programming problem.To efficiently solve the problem,we divide it into an inner-layer and outer-layer optimization sub-problems.The inner-layer optimization which is formulated to maximize the sub-carrier PA coefficients can be transformed into the difference of convex programming by using the first-order Taylor expansion.Based on the solution of the inner-layer optimization sub-problem,the concave-convex fractional programming problem of the outer-layer optimization sub-problem may be converted into the Lagrangian relaxation model employing the Dinkelbach algorithm.Simulation results demonstrate that the proposed algorithm has a faster convergence speed than the simulated annealing algorithm,while the average system EE loss is only less than 2%. | Guangfu Wu Wenyi Zheng Yun Li Mengyuan Zhou | 2021 | China Communications2021，18，4： | 1 |

| 12 | Fabrication of extracellular matrix-coated conductive polypyrrolepoly(L-lactide)fiber-films and their synergistic effect with(nerve growth factor)/(epidermal growth factor) on neurites growth显示文摘Non-nerve cell-derived extracellular matrix(ECM)wa s coated on the aligned porous polypyrrole-poly(Llactide)(PPy-PLLA)fiber-films with the conductivity of^12 mS/m via L929 cells culture and lysing,resulting in^10%increase of PC12 cells attachment and^26μm increase of neurites length.The neurite length of^149μm in EGF/NGF group(optimal concentration radio of 12.5/50(ng/mL))on aligned and ECM-conjugated fiber-films was significantly larger than^94μm in only NGF group(50 ng/mL),confirming the synergy of EGF,NGF and aligned ECM-conjuaged PPy-PLLA fibers.When differentiated PC12 cells were exerted electrical stimulation(ES)of 100 mV/cm for 4 h/day in 2 day through ECM-PPyPLLA fiber-films,their neurite length reached to^251μm,significantly larger than^149μm of group without ES,due to the higer expression of related neural proteins in ES group.A simple mechanism was proposed to analyze synergistical effect of ECM,EGF,NGF on axons adhesion and elongation along the aligned ECM-coated fibers under ES condition. | Ximing Pu Xingxing Zhou Zhongbing Huang Guangfu Yin Xianchun Chen | 2020 | Chinese Chemical Letters2020，31，5： | 1 |

| 14 | Object Recognition Based on Improved Context Model显示文摘An object recognition method is proposed in this paper by introducing the spatial location relationship of objects into the context model. The spatial-position information of the objects is first utilized to model the context model. The model parameters and dependency structure of objects can be learned by integrating the context information into the same probabilistic framework. The image recognition is accomplished by using the advantages of efficient inference of the tree structure model. The proposed method can greatly improve the object recognition rate and better keep the consistency of scenes. The effectiveness of the proposed algorithm is verified by testing and comparing with other existing algorithms in the actual dataset. | WEN Chenglin ZHOU Guangfu GAO Jingli LI Hongwei XU Xiaobin | 2018 | Chinese Journal of Electronics2018，27，3： | 1 |
| 15 | Identification of A-to-I RNA editing profiles and their clinical relevance in lung adenocarcinoma显示文摘Adenosine-to-inosine(A-to-I)RNA editing is a widespread posttranscriptional modification that has been shown to play an important role in tumorigenesis.Here,we evaluated a total of 19,316 RNA editing sites in the tissues of 80 lung adenocarcinoma(LUAD)patients from our Nanjing Lung Cancer Cohort(NJLCC)and 486 LUAD patients from the TCGA database.The global RNA editing level was significantly increased in tumor tissues and was highly heterogeneous across patients.The high RNA editing level in tumors was attributed to both RNA(ADAR1 expression)and DNA alterations(mutation load).Consensus clustering on RNA editing sites revealed a new molecular subtype(EC3)that was associated with the poorest prognosis of LUAD patients.Importantly,the new classification was independent of classic molecular subtypes based on gene expression or DNA methylation.We further proposed a simplified model including eight RNA editing sites to accurately distinguish the EC3 subtype in our patients.The model was further validated in the TCGA dataset and had an area under the curve(AUC)of the receiver operating characteristic curve of 0.93(95%CI:0.91-0.95).In addition,we found that LUAD cell lines with the EC3 subtype were sensitive to four chemotherapy drugs.These findings highlighted the importance of RNA editing events in the tumorigenesis of LUAD and provided insight into the application of RNA editing in the molecular subtyping and clinical treatment of cancer. | Cheng Wang Mingtao Huang Congcong Chen Yuancheng Li Na Qin Zijian Ma Jingyi Fan Linnan Gong Hui Zeng Liu Yang Xianfeng Xu Jun Zhou Juncheng Dai Guangfu Jin Zhibin Hu Hongxia Ma Fengwei Tan Hongbing Shen | 2022 | Science China(Life Sciences)2022，65，1： | 1 |
| 16 | A nomogram predicting clinical pregnancy in the first fresh embryo transfer for women undergoing in vitro fertilization and intracytoplasmic sperm injection(IVF/ICSI) treatments显示文摘The extent to which factors affect the probability of clinical pregnancy in the first fresh embryo transfer after assisted conception is unknown.In order to examine the predictors of clinical pregnancy,a retrospective cohort study was launched between January 1,2013 and December 31,2016 in four infertility clinics including 19837 in vitro fertilization and intracytoplasmic sperm injection(IVF/ICSI)fresh cycles with known outcomes and relevant records.A multivariable logistic regression was used to select the most significant predictors in the final nomogram for predicting clinical pregnancy.Furthermore,the model was validated by an independent validation set and the performance of the model was evaluated by the receiver operating characteristic(ROC)curves along with the area under the ROC curve(AUC)and calibration plots.In a training set including 17854 participants,we identified that female age,tubal factor,number of embryos transferred,endometrial thickness and number of good-quality embryos were independent predictors for clinical pregnancy.We developed a nomogram using these five factors and the predictive ability was 0.66 for AUC(95%CI=0.64−0.68),which was independently validated in the validation set(AUC=0.66,95%CI=0.65−0.68).Our results show that some specific factors can be used to provide infertile couples with an accurate assessment of clinical pregnancy following assisted conception and facilitate to guide couples and clinicians. | Fang Wu Feng Liu Yichun Guan Jiangbo Du Jichun Tan Hong Lv Qun Lu Shiyao Tao Lei Huang Kun Zhou Yankai Xia Xinru Wang Hongbing Shen Xiufeng Ling Feiyang Diao Zhibin Hu Guangfu Jin | 2019 | The Journal of Biomedical Research2019，33，6： | 1 |

| 18 | Polymorphisms of TLR7 and TLR8 associated with risk of asthma and asthma-related phenotypes in a southeastern Chinese Han population显示文摘Objective:To evaluate the effects of polymorphisms in TLR7 and TLR8(as potential candidate genes) on asthma risk and asthma-related phenotypes. Methods: We consecutively recruited 318 unrelated adult asthmatic patients and 352 healthy volunteers from the same area of southeast China. Genotyping of each selected SNP was performed using multiplex PCR in conjunction with tagged array single base extension technology. We conducted case-control and case-only association studies between the selected SNPs in TLR7 and TLR8 and asthma or asthma-related phenotypes. Results: The T allele of rs5935436 SNP in TLR7 was protective from developing asthma in males (adjusted ORs=0.126,95% CIs=0.016-0.995). The CT/TT genotype of rs5935436 was less frequent in female asthmatics with allergic rhinitis (adjusted ORs=0.18,95% CIs=0.04-0.90). The homozygote AA of rs3761623 and GG of rs3764880 were positively associated with lower FEV1% and asthma severity in female asthmatics. These results were confirmed by haplotype analysis. Conclusion:TLR7 and TLR8 polymorphisms may play an important role in the pathogenesis of asthma that is gender-dependent. This could be clinically useful,both for identifying patients at risk of asthma and for preventing its occurrence. | Qian Zhang Fenhong Qian Linfu Zhou Guozhen Wei Ying Wang Zhibin Hu Guangfu Jin Jianling Bai Kaisheng Yin | 2009 | Journal of Nanjing Medical University2009，23，1： | 1 |
