| 1 | Analyses on the tectonic thermal evolution and influence factors in the deep-water Qiongdongnan Basin显示文摘To reveal the tectonic thermal evolution and influence factors on the present heat flow distribution, based on 154 heat flow data, the present heat flow distribution features of the main tectonic units are first analyzed in detail, then the tectonic thermal evolution histories of 20 profiles are reestablished crossing the main deep-water sags with a structural, thermal and sedimentary coupled numerical model. On the basis of the present geothermal features, the Qiongdongnan Basin could be divided into three regions: the northern shelf and upper slope region with a heat flow of 50–70 m W/m2, most of the central depression zone of 70–85 m W/m2, and a NE trending high heat flow zone of 85–105 m W/m2 lying in the eastern basin. Numerical modeling shows that during the syn-rift phase, the heat flow increases generally with time, and is higher in basement high area than in its adjacent sags. At the end of the syn-rift phase, the heat flow in the deepwater sags was in a range of 60–85 m W/m2, while in the basement high area, it was in a range of 75–100 m W/m2. During the post-rift phase, the heat flow decreased gradually, and tended to be more uniform in the basement highs and sags. However, an extensive magmatism, which equivalently happened at around 5 Ma, has greatly increased the heat flow values, and the relict heat still contributes about 10–25 m W/m2 to the present surface heat flow in the central depression zone and the southern uplift zone. Further analyses suggested that the present high heat flow in the deep-water Qiongdongnan Basin is a combined result of the thermal anomaly in the upper mantle, highly thinning of the lithosphere, and the recent extensive magmatism. Other secondary factors might have affected the heat flow distribution features in some local regions. These factors include basement and seafloor topography, sediment heat generation, thermal blanketing, local magmatic injecting and hydrothermal activities related to faulting and overpressure. | WANG Zhenfeng SHI Xiaobin YANG Jun HUANG Baojia SUN Zhen WANG Yahui JIANG Haiyan YU Chuanhai YANG Xiaoqiu | 2014 | Acta Oceanologica Sinica2014，33，12： | 22 |

| 3 | New Algorithm for CBR-RBR Fusion with Robust Thresholds显示文摘The case-based reasoning(CBR) and rule-based reasoning(RBR) fusion systems include a diverse range of fusion methods and their tasks are characterized by interleaving combination of the reasoning procedures. Existing approaches cannot clarify the complex relationships between data from the knowledge sources nor uniformly represent the heterogeneous case and rule knowledge in one fusion space. As a result, existing approaches fail to solve system fragility due to knowledge uncertainty and reasoning unreliability. For the purpose of addressing the difficulties, a novel algorithm for CBR-RBR fusion with robust thresholds(CRFRT) is proposed. Heterogeneous case and rule knowledge are uniformly represented in one defined fusion unitary space. The robust thresholds have been achieved to distinguish the complex relationships between meta-knowledge in the fusion space and to enhance system capacity of knowledge identification. Furthermore, fusion reasoning strategies are constructed for CRFRT and its procedure based on which robust solution of the fusion reasoning problem is obtained. Finally, CRFRT is validated by benchmark problems in machine learning. Compared with other CBR and RBR approaches, the reasoning efficiency and accuracy are increased by 5% and 2.2% respectively. The variations of system accuracy are decreased by 2% to 3.8%. The above results show that the CRFRT algorithm boosts the system's effectiveness and robustness. The proposed CRFRT can solve the fragility of complex intelligence decision system and give quality performance for fault diagnosis. | XU Mad YU Haiyan SHEN Jiang | 2012 | Chinese Journal of Mechanical Engineering2012，25，6： | 12 |

| 5 | Tensile properties of high strength cast Mg alloys at room temperature:A review显示文摘As most Mg alloy products are now produced by a casting process,the development of high strength cast Mg alloys can promote their further applications and has already become one of the hot research areas of Mg alloys.The present paper reviews the strengthening mechanisms,tensile properties and modification results of commercial high strength cast Mg alloys;as well as the development of Mg-Gd,Mg-Nd and Mg-Sn based alloys.It concludes that precipitation strengthening is the most important strengthening mechanism in high strength cast Mg alloys,which contributes more than 60%of yield strength in solution&peak-aged(T6)cast Mg alloys.For the yield strength,the alloys follow the sequence of Mg-Gd(Y)-Ag>Mg-Gd(Y)-Zn>Mg-Gd-Y/Sm/Nd>Mg-Y-Nd(WE series)>ZK61>Mg-Nd>AZ91>Mg-Sn.Mg-Gd(Y)-Ag based alloys are the strongest cast Mg alloys at present,followed by Mg-Gd(Y)-Zn based alloys.The high yield strengths of Mg-Gd(Y)-Ag and Mg-Gd(Y)-Zn cast alloys are due to the co-precipitation of basal and prismatic meta-stable phases. | Fu Penghuai Peng Liming Jiang Haiyan Ding Wenjiang Zhai Chunquan | 2014 | China Foundry2014，11，4： | 12 |

| 7 | OTOTOXIC MODEL OF OXALIPLATIN AND PROTECTION FROM NICOTINAMIDE ADENINE DINUCLEOTIDE显示文摘Oxaliplatin,an anticancer drug commonly used to treat colorectal cancer and other tumors,has a number of serious side effects,most notably neuropathy and ototoxicity.To gain insights into its ototoxic profile,oxaliplatin was applied to rat cochlear organ cultures.Consistent with it neurotoxic propensity,oxaliplatin selectively damaged nerve fibers at a very low dose 1μM.In contrast,the dose required to damage hair cells and spiral ganglion neurons was 50 fold higher(50μM).Oxailiplatin-induced cochlear lesions initially increased with dose,but unexpectedly decreased at very high doses.This non-linear dose response could be related to depressed oxaliplatin uptake via active transport mechanisms.Previous studies have demonstrated that axonal degeneration involves biologically active processes which can be greatly attenuated by nicotinamide adenine dinucleotide(NAD+).To determine if NAD+would protect spiral ganglion axons and the hair cells from oxaliplatin damage,cochlear cultures were treated with oxaliplatin alone at doses of 10μM or 50μM respectively as controls or combined with 20 mM NAD+.Treatment with 10μM oxaliplatin for 48 hours resulted in minor damage to auditory nerve fibers,but spared cochlear hair cells.However,when cochlear cultures were treated with 10μM oxaliplatin plus 20 mM NAD+,most auditory nerve fibers were intact.50μM oxaliplatin destroyed most of spiral ganglion neurons and cochlear hair cells with apoptotic characteristics of cell fragmentations.However,50μM oxaliplatin plus 20 mM NAD+treatment greatly reduced neuronal degenerations and hair cell missing.The results suggested that NAD+provides significant protection against oxaliplatin-induced neurotoxicity and ototoxicity,which may be due to its actions of antioxidant,antiapoptosis,and energy supply. | DING Dalian JIANG Haiyan FU Yong LI Yongqi Richard Salvi Shinichi Someya Masaru Tanokura | 2013 | Journal of Otology2013，8，1： | 9 |

| 9 | Effect of electroacupuncture on chemotherapy-induced peripheral neuropathy in patients with malignant tumor:a single-blinded,randomized controlled trial显示文摘OBJECTIVE:To evaluate the effect of electroacupuncture on chemotherapy-induced peripheral neuropathy(CIPN), quality of life and immune status of patients with malignant tumors.METHODS:From Jan, 2013 to May, 2014, 37 patients with malignant tumors were included in this prospective single-blinded study, and randomized to receive either electroacupuncture or acupuncture treatment on basis of chemotherapy.The chemotherapy was continued for 2 courses as previous before the treatments, with 21 days as a course of treatment.Patients received acupuncture and electroacupuncture once per day starting at the day before chemotherapy for consecutive 7 days followed by 14 days off, with 21 days as a course of treatment, and continued for two courses of treatment.Then CIPN, traditional Chinese clinical symptoms,quality of life and immune status were all evaluated for each patient prior treatment and after two courses of treatment.RESULTS:The gender, age, cancer species as well as incidence(83.3% vs 84.2%) and grades of CIPN before treatments were all similar in patients receiving acupuncture or electroacupuncture(all P >0.05).After treatments, most patients with peripheral neuropathy were cured by two courses of electroacupuncture(84.2% vs 21.1%), whereas the other group of patients had similar incidences of peripheral neuropathy compared with prior-acupuncture(83.3% vs 72.2%).Besides, patients receiving electroacupuncture had lower incidence of peripheral neuropathy than those receiving acupuncture treatment(χ~2= 9.745, P = 0.002).The grades of peripheral neuropathy were significantly different in the two groups post-treatment(χ~2= 13.983, P =0.007).The total effective rates for traditional Chinese clinical symptoms were 16.7% and 84.2% in acupuncture and electroacupuncture groups, respectively(Z =-4.239, P < 0.001).The electroacupuncture treatment provided a more satisfactory life for patients compared with acupuncture(Z =-4.76, P < 0.001).Both electroacupuncture and acupuncture had no effects on immune function.CONCLUSION:Electroacupuncture could alleviate CIPN, and improve traditional Chinese clinical symptoms and quality of life, but did not affect immune function. | Zhang Shiqiang Wu Tingting Zhang Haisheng Yang Yun Jiang Haiyan Cao Shengcheng Xie Fang Xia Xiaoting Lü Junqiang Zhong Yi | 2017 | Journal of Traditional Chinese Medicine2017，37，2： | 7 |
| 10 | New approach to eliminate structural redundancy in case resource pools using α mutual information显示文摘Structural redundancy elimination in case resource pools (CRP) is critical for avoiding performance bottlenecks and maintaining robust decision capabilities in cloud computing services. For these purposes, this paper proposes a novel approach to ensure redundancy elimination of a reasoning system in CRP. By using α entropy and mutual information, functional measures to eliminate redundancy of a system are developed with respect to a set of outputs. These measures help to distinguish both the optimal feature and the relations among the nodes in reasoning networks from the redundant ones with the elimination criterion. Based on the optimal feature and its harmonic weight, a model for knowledge reasoning in CRP (CRPKR) is built to complete the task of query matching, and the missing values are estimated with Bayesian networks. Moreover, the robustness of decisions is verified through parameter analyses. This approach is validated by the simulation with benchmark data sets using cloud SQL. Compared with several state-of-the-art techniques, the results show that the proposed approach has a good performance and boosts the robustness of decisions. | Man Xu Haiyan Yu Jiang Shen | 2013 | Journal of Systems Engineering and Electronics2013，24，4： | 6 |

| 12 | Hydrothermal fabrication and visible-light-driven photocatalytic properties of bismuth vanadate with multiple morphologies and/or porous structures for Methyl Orange degradation显示文摘Monoclinic BiVO4 with multiple morphologies and/or porous structures were fabricated using the hydrothermal strategy. The materials were characterized by means of the XRD, Raman, TGA/DSC, SEM, XPS, and UV-Vis techniques. The photocatalytic activities of the BiVO4 materials were evaluated for the degradation of Methyl Orange under visible-light irradiation. It is observed that pH value and surfactant exerted a great effect on the morphology and pore structure of the BiVO4 product. Spherical BiVO4 with porous structures, flower-cluster-like BiVO4, and flower-bundle-like BiVO4 were generated hydrothermally at 100°C with poly(vinyl pyrrolidone) (PVP) and urea (pH = 2) and at 160°C with NaHCO3 (pH = 7 and 8), respectively. The PVP-derived BiVO4 showed much higher surface areas (5.0-8.4 m2/g) and narrower bandgap energies (2.45-2.49 eV). The best photocatalytic performance of the spherical BiVO4 material with a surface area of 8.4 m2/g was associated with its higher surface area, narrower bandgap energy, higher surface oxygen vacancy density, and unique porous architecture. | Haiyan Jiang Hongxing Dai Xue Meng Lei Zhang Jiguang Deng Yuxi Liu Chak Tong Au | 2012 | Journal of Environmental Sciences2012，24，3： | 5 |
| 13 | Seasonal Variations of Several Main Water Masses in the Southern Yellow Sea and East China Sea in 2011显示文摘The seasonal variations of several main water masses in the southern Yellow Sea (SYS) and East China Sea (ECS) in 2011 were analyzed using the in-situ data collected on four cruises.There was something special in the observations for the Yellow Sea Warm Current (YSWC) ,the Yellow Sea Cold Water Mass (YSCWM) and the Changjiang Diluted Water (CDW) during that year.The YSWC was confirmed to be a seasonal current and its source was closely associated with the Kuroshio onshore intrusion and the northerly wind.It was also found that the YSCWM in the summer of 2011 occupied a more extensive area in comparison with the climatologically-mean case due to the abnormally powerful wind prevailing in the winter of 2010 and decaying gradually thereafter.Resulting from the reduced Changjiang River discharge,the CDW spreading toward the Cheju Island in the summer of 2011 was weaker than the long-term mean and was confined to flow southward in the other seasons.The other water masses seemed normal without noticeable anomalies in 2011.The Yellow Sea Coastal Current (YSCC) water,driven by the northerly wind,flowed southeastward as a whole except for its northeastward surface layer in summer.The Taiwan Warm Current (TWC) was the strongest in summer and the weakest in winter in its northward movement.The Kuroshio water with an enhanced onshore intrusion in autumn was stable in hydrographic features apart from the seasonal variation of its surface layer. | QUAN Qi MAO Xinyan YANG Xiaodan HU Yingying ZHANG Haiyan JIANG Wensheng | 2013 | Journal of Ocean University of China2013，12，4： | 5 |
| 14 | A Day-ahead Economic Dispatch Method Considering Extreme Scenarios Based on Wind Power Uncertainty显示文摘As the intermittency of wind power is a growing concern in the day-ahead economic dispatch,this paper proposes a day-ahead economic dispatch method considering extreme scenarios of wind power by using an uncertainty set.The uncertainty set inspired by robust optimization is used to describe wind power intermittency in this paper.Four extreme scenarios based on the uncertainty set are formulated to represent the worst cases of wind power fluctuation.An economic dispatch method considering the costs of both load shedding and wind curtailment is proposed.The economic dispatch model can be easily solved by a quadratic programming method owing to the introduction of four extreme scenarios and the uncertainty set of wind power.Simulation is done using the IEEE 30-bus system and the results verify the effectiveness of the proposed method. | Jian Xu Bao Wang Yuanzhang Sun Qi Xu Ji Liu Huiqiu Cao Haiyan Jiang Ruobing Lei Mengjun Shen | 2019 | CSEE Journal of Power and Energy Systems2019，5，2： | 5 |

| 16 | RNA Editing Sites Exist in Protein-coding Genes in the Chloroplast Genome of Cycas taitungensis显示文摘RNA editing is a post-transcriptional process that results in modifications of ribonucleotides at specific locations.In land plants editing can occur in both mitochondria and chloroplasts and most commonly involves C-to-U changes,especially in seed plants.Using prediction and experimental determination,we investigated RNA editing in 40 protein-coding genes from the chloroplast genome of Cycas taitungensis.A total of 85 editing sites were identified in 25 transcripts.Comparison analysis of the published editotypes of these 25 transcripts in eight species showed that RNA editing events gradually disappear during plant evolution.The editing in the first and third codon position disappeared quicker than that in the second codon position.ndh genes have the highest editing frequency while serine and proline codons were more frequently edited than the codons of other amino acids.These results imply that retained RNA editing sites have imbalanced distribution in genes and most of them may function by changing protein structure or interaction.Mitochondrion protein-coding genes have three times the editing sites compared with chloroplast genes of Cycas,most likely due to slower evolution speed. | Haiyan Chen Likun Deng Yuan Jiang Ping Lu Jianing Yu | 2011 | Journal of Integrative Plant Biology2011，53，12： | 5 |

| 18 | 16S rRNA Gene Phylogenesis of Culturable Predominant Bacteria from Diseased Apostichopus japonicus(Holothuroidea,Echinodermata)显示文摘Cultured Apostichopus japonicus in China suffers from a kind of skin ulceration disease that has caused severe economic loss in recent years. The disease,pathogens of which are supposed to be bacteria by most researchers,is highly infectious and can often cause all individuals in the same culture pool to die in a very short time. The 16S rRNA gene phylogenesis of the culturable bacteria from the lesions of diseased individuals was conducted to study the biodiversity of the bacterial communities in the lesions and to identify probable pathogen(s) associated with this kind of disease. S. japonica samples were selected from a hatchery located in the eastern part of Qingdao,China. Bacterial universal primers GM5F and DS907R were used to amplify the 16S rRNA gene of bacteria colonies,and touchdown PCR was performed to amplify the target sequences. The results suggest that γ-proteobacteria(Alteromonadales and Vibrionales) of CFB group,many strains of which have been also determined as pathogens in other marine species,are the predominant bacterial genera of the diseased Apostichopus japonicus individuals. | MA Haiyan JIANG Guoliang WU Zhiqiang WANG Xin | 2009 | Journal of Ocean University of China2009，8，2： | 4 |
| 19 | Early diagenetic growth of carbonate concretions in the upper Doushantuo Formation in South China and their significance for the assessment of hydrocarbon source rock显示文摘Mineralogical and textural characteristics and organic carbon composition of the carbonate concretions from the upper Doushantuo Formation (ca. 551 Ma) in the eastern Yangtze Gorge area reveal their early diagenetic (shallow) growth in organic-rich shale. High organic carbon content (up to 10%) and abundance of framboidal pyrites in the hosting shale suggest an anoxic or euxinic depositional environment. Well-preserved cardhouse clay fabrics in the concretions suggest their formation at 0-3 m burial depth, likely associated with microbial decomposition of organic matter and anaerobic oxidation of methane. Gases through decomposition of organic matter and/or from methanogenesis created bubbles and cavities, and anaerobic methane oxidation at the sulfate reduction zone resulted in carbonate precipitation, filling in bubbles and cavities to form spherical structures of the concretions. Rock pyrolysis analyses show that the carbonate concretions have lower total organic carbon (TOC) content but higher effective carbon than those in the host rocks. This may be caused by enclosed organic matter in pores of the concretions so that organic matter was protected from further modification during deep burial and maintained high hydrocarbon generating potential even in over-matured source rock. As a microbialite sensu latu, concretions have special growth conditions and may provide important information on the microbial activities in depositional and early burial environments. | DONG Jin ZHANG ShiHong JIANG GanQing ZHAO QingLe LI HaiYan SHI XiaoYing LIU JunLai | 2008 | Science China Earth Sciences2008，51，9： | 4 |
| 20 | QTL mapping for grain number per spikelet in wheat using a high-density genetic map显示文摘Grain number per spikelet (GNS) is a key determinant of grain yield in wheat.A recombinant inbred line population comprising 300 lines was developed from a cross between a high GNS variety H461 and Chinese Spring from which the reference genome assembly of bread wheat was obtained.Both parents and the recombinant inbred lines were genotyped using the wheat 55K single nucleotide polymorphism(SNP) array.A high-density genetic map containing 21,197 SNPs was obtained.These markers covered each of the 21 chromosomes with a total linkage distance of 3792.71 c M.Locations of these markers in this linkage map were highly consistent with their physical locations in the genome assembly of Chinese Spring.The two parents and the whole RIL population were assessed for GNS in two consecutive years at two different locations.Based on multi-environment phenotype data and best liner unbiased prediction values,three quantitative trait loci (QTL) for GNS were identified.One of them located on chromosomes 2B and the other two on 2D.Phenotypic variation explained by these loci varied from 3.07%to26.57%.One of these QTL,QGns.sicau-2D-2,was identified in each of all trials conducted.Based on the best linear unbiased prediction values,this locus explained 19.59%–26.57%of phenotypic variation.A KASP(Kompetitive Allele-Specific PCR) marker closely linked with this locus was generated and used to validate the effects of this locus in three different genetic backgrounds.The identified QTL and the KASP marker developed for it will be highly valuable in fine-mapping the locus and in exploiting it for markerassisted selection in wheat breeding programs. | Yu Lin Xiaojun Jiang Haiyan Hu Kunyu Zhou Qing Wang Shifan Yu Xilan Yang Zhiqiang Wang Fangkun Wu Shihang Liu Caixia Li Mei Deng Jian Ma Guangdeng Chen Yuming Wei Youliang Zheng Yaxi Liu | 2021 | The Crop Journal2021，9，5： | 4 |
