| 1 | Antioxidant effects of the orientin and vitexin in Trollius chinensis Bunge in D-galactose-aged mice显示文摘Total flavonoids are the main pharmaceutical components of Trollius chinensis Bunge, and orientin and vitexin are the monomer components of total flavonoids in Trollius chinensis Bunge. In this study, an aged mouse model was established through intraperitoneal injection of D-galactose for 8 weeks, followed by treatment with 40, 20, or 10 mg/kg orientin, vitexin, or a positive control (vitamin E) via intragastric administration for an additional 8 weeks. Orientin, vitexin, and vitamin E improved the general medical status of the aging mice and significantly increased their brain weights. They also produced an obvious rise in total antioxidant capacity, superoxide dismutase, catalase, and glutathione peroxidase levels in the serum, and the levels of superoxide dismutase, catalase and glutathione peroxidase, Na+-K+-ATP enzyme, and Ca2+-Mg2+-ATP enzyme in the liver, brain and kidneys. In addition, they significantly reduced malondialdehyde levels in the liver, brain and kidney and lipofuscin levels in the brain. They also significantly improved the neuronal ultrastructure. The 40 mg/kg dose of orientin and vitexin had the same antioxidant capacity as vitamin E. These experimental findings indicate that orientin and vitexin engender anti-aging effects through their antioxidant capacities. | Fang An Guodong Yang Jiaming Tian Shuhua Wang | 2012 | Neural Regeneration Research2012，7，33： | 20 |
| 2 | 盆地演化认识中的几个问题显示文摘本文论述了盆地演化认识中的几个主要问题。一是陆缘裂解过程,华南边缘传统上认为是被动裂谷边缘的一个例子,其东部沉积物记录了压实的历史,它明显不同于被动裂谷作用模式,而是显示早第三纪大规模上隆和侵蚀的特征;而且,该地区覆盖在下地壳楔形体上面,具有比周围地壳明显要高的地震速度和密度,指示岩浆底侵作用。这些证据说明,与被动裂谷作用模式相比,华南边缘与主动裂谷作用模式较为一致,它是由早第三纪华南边缘东部底下地幔柱形成的主动裂谷。另一个问题是关于页岩的浅部破裂作用机理。大多数研究者认为,微裂隙的形成需要高孔隙压力,它限于深埋、低渗透率的岩石。然而,最近从北海观察表明,在第三纪页岩中,整个盆地范围内的破裂型式从未达到大于几百米的埋藏深度。这说明泥质源岩经历了水压破裂和浅部脱水,在破裂前可能达到深埋后生作用所需要的深度,实质上渗透率的改变是由于源岩的浅部破裂作用可能根本上改变了烃类的初次运移时间和效率。 | Wang Chiyuen(Department of Geology and Geophysics University of California,Berkeley,CA 94720)Yang Jiaming Zhu Weilin(Exploration and Development Research Center,China National Offshore Oil Corporation,Xincheng,074010)Zheng Mingling(Scientific Research Ce | 1995 | 地学前缘1995，2，3： | 14 |
| 3 | Single-cell transcriptomic atlas of primate cardiopulmonary aging显示文摘Aging is a major risk factor for many diseases,especially in highly prevalent cardiopulmonary comorbidities and infectious diseases including Coronavirus Disease 2019(COVID-19).Resolving cellular and molecular mechanisms associated with aging in higher mammals is therefore urgently needed.Here,we created young and old non-human primate single-nucleus/cell transcriptomic atlases of lung,heart and artery,the top tissues targeted by SARS-CoV-2.Analysis of cell type-specific aging-associated transcriptional changes revealed increased systemic inflammation and compromised virus defense as a hallmark of cardiopulmonary aging.With age,expression of the SARS-CoV-2 receptor angiotensin-converting enzyme 2(ACE2)was increased in the pulmonary alveolar epithelial barrier,cardiomyocytes,and vascular endothelial cells.We found that interleukin 7(IL7)accumulated in aged cardiopulmonary tissues and induced ACE2 expression in human vascular endothelial cells in an NF-κB-dependent manner.Furthermore,treatment with vitamin C blocked IL7-induced ACE2 expression.Altogether,our findings depict the first transcriptomic atlas of the aged primate cardiopulmonary system and provide vital insights into age-linked susceptibility to SARS-CoV-2,suggesting that geroprotective strategies may reduce COVID-19 severity in the elderly. | Shuai Ma Shuhui Sun Jiaming Li Yanling Fan Jing Qu Liang Sun Si Wang Yiyuan Zhang Shanshan Yang Zunpeng Liu Zeming Wu Sheng Zhang Qiaoran Wang Aihua Zheng Shuguang Duo Yang Yu Juan Carlos Izpisua Belmonte Piu Chan Qi Zhou Moshi Song Weiqi Zhang Guang-Hui Liu | 2021 | Cell Research2021，31，4： | 10 |
| 4 | Highly expressed BMP9/GDF2 in postnatal mouse liver and lungs may account for its pleiotropic effects on stem cell differentiation,angiogenesis,tumor growth and metabolism显示文摘Bone morphogenetic protein 9(BMP9)(or GDF2)was originally identified from fetal mouse liver cDNA libraries.Emerging evidence indicates BMP9 exerts diverse and pleiotropic functions during postnatal development and in maintaining tissue homeostasis.However,the expression landscape of BMP9 signaling during development and/or in adult tissues remains to be analyzed.Here,we conducted a comprehensive analysis of the expression landscape of BMP9 and its signaling mediators in postnatal mice.By analyzing mouse ENCODE transcriptome datasets we found Bmp9 was highly expressed in the liver and detectable in embryonic brain,adult lungs and adult placenta.We next conducted a comprehensive qPCR analysis of RNAs isolated from major mouse tissues/organs at various ages.We found that Bmp9 was highly expressed in the liver and lung tissues of young adult mice,but decreased in older mice.Interestingly,Bmp9 was only expressed at low to modest levels in developing bones.BMP9-associated TGFβ/BMPR type I receptor Alk1 was highly expressed in the adult lungs.Furthermore,the feedback inhibitor Smads Smad6 and Smad7 were widely expressed in mouse postnatal tissues.However,the BMP signaling antagonist noggin was highly expressed in fat and heart in the older age groups,as well as in kidney,liver and lungs in a biphasic fashion.Thus,our findings indicate that the circulating BMP9 produced in liver and lungs may account for its pleiotropic effects on postnatal tissues/organs although possible roles of BMP9 signaling in liver and lungs remain to be fully understood. | Wei Liu Zhongliang Deng Zongyue Zeng Jiaming Fan Yixiao Feng Xi Wang Daigui Cao Bo Zhang Lijuan Yang Bin Liu Mikhail Pakvasa William Wagstaff Xiaoxing Wu Huaxiu Luo Jing Zhang Meng Zhang Fang He Yukun Mao Huiming Ding Yongtao Zhang Changchun Niu Rex C.Haydon Hue H.Luu Jennifer Moriatis Wolf Michael J.Lee Wei Huang Tong-Chuan He Yulong Zou | 2020 | Genes & Diseases2020，7，2： | 9 |
| 5 | Interferon-armed RBD dimer enhances the immunogenicity of RBD for sterilizing immunity against SARS-CoV-2显示文摘Severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)has caused a global crisis,urgently necessitating the development of safe,efficacious,convenient-to-store,and low-cost vaccine options.A major challenge is that the receptor-binding domain(RBD)-only vaccine fails to trigger long-lasting protective immunity if used alone for vaccination. | Shiyu Sun Yueqi Cai Tian-Zhang Song Yang Pu Lin Cheng Hairong Xu Jing Sun Chaoyang Meng Yifan Lin Haibin Huang Fang Zhao Silin Zhang Yu Gao Jian-Bao Han Xiao-Li Feng Dan-Dan Yu Yalan Zhu Pu Gao Haidong Tang Jincun Zhao Zheng Zhang Jiaming Yang Zhenxiang Hu Yang-Xin Fu Yong-Tang Zheng Hua Peng | 2021 | Cell Research2021，31，9： | 7 |
| 6 | Correlation of Gut Microbiome Between ASD Children and Mothers and Potential Biomarkers for Risk Assessment显示文摘Variation of maternal gut microbiota may increase the risk of autism spectrum disorders(ASDs) in offspring. Animal studies have indicated that maternal gut microbiota is related to neurodevelopmental abnormalities in mouse offspring, while it is unclear whether there is a correlation between gut microbiota of ASD children and their mothers. We examined the relationships between gut microbiome profiles of ASD children and those of their mothers, and evaluated the clinical discriminatory power of discovered bacterial biomarkers. Gut microbiome was profiled and evaluated by 16S ribosomal RNA gene sequencing in stool samples of 59 mother–child pairs of ASD children and 30 matched mother–child pairs of healthy children. Significant differences were observed in the gut microbiome composition between ASD and healthy children in our Chinese cohort. Several unique bacterial biomarkers, such as Alcaligenaceae and Acinetobacter, were identified. Mothers of ASD children had more Proteobacteria, Alphaproteobacteria, Moraxellaceae, and Acinetobacter than mothers of healthy children. There was a clear correlation between gut microbiome profiles of children and their mothers; however, children with ASD still had unique bacterial biomarkers, such as Alcaligenaceae, Enterobacteriaceae, and Clostridium. Candidate biomarkers discovered in this study had remarkable discriminatory power. The identified patterns of mother–child gut microbiome profiles may be important for assessing risks during the early stage and planning of personalized treatment and prevention of ASD via microbiota modulation. | Ning Li Junjie Yang Jiaming Zhang Cheng Liang Ying Wang Bin Chen Changying Zhao Jingwen Wang Guangye Zhang Dongmei Zhao Yi Liu Lehai Zhang Jun Yang Guimei Li Zhongtao Gai Lei Zhang Guoping Zhao | 2019 | Genomics, Proteomics & Bioinformatics2019，17，1： | 6 |
| 7 | Artificial Selection in Domestication and Breeding Prevents Speciation in Rice显示文摘Speciation has long been regarded as an irreversible process once the reproductive barriers had been established.However,unlike in natural populations,artificial selection might either accelerate or prevent speciation processes in domesticated species.Asian cultivated rice is a target crop for both domestication and artificial breeding;it contains two subspecies of indica and japonica,which usually produce sterile inter-subspecific hybrids due to reproductive barriers.In this study,we constructed the evolutionary trajectory of a reproductive isolation system S5,which regulates fertility in indica-japonica hybrids via three adjacent genes,based on the data of 606 accessions including two cultivated and 11 wild rice species.Although hybrid sterility haplotypes at S5 lead to establishment of a killer-protector reproductive barrier,origin of wide-compatibility haplotypes by complex hybridization and recombination provides an opposing force to reproductive isolation and thus prevents speciation during domestication.Analysis in a diallel set of 209 crosses involving 21 parents showed that the wide-compatibility genotypes largely rescued fertility of indica-japonica hybrids,indicating that the wide-compatibility gene would enable gene flow to maintain species coherence.This counteracting system indicates that combined effects of natural evolution and artificial selection may result in reversible processes of speciation in rice,which may also have implications for genetic improvement of rice. | Jiaming Mi Guangwei Li Conghao Xu Jiangyi Yang Huihui Yu Gongwei Wang Xianghua Li Jinghua Xiao Huazhi Song Qifa Zhang Yidan Ouyang | 2020 | Molecular Plant2020，13，4： | 6 |

| 9 | Anatomical variation of infra-pyloric artery origination: A prospective multicenter observational study (IPA-Origin)显示文摘Objective: Infra-pyloric artery(IPA) is an important anatomical landmark in treatment of gastric cancer and is the key vessel for pylorus-preserving gastrectomy and subgroup of infra-pyloric lymph nodes. However, its anatomical variation is not thoroughly understood. Our study aimed to clarify the origination of the IPA.Methods: We did this prospective, multicenter, open-label, observational study at gastric surgery departments of34 hospitals in China. Gastric cancer patients aged 18 years or older and scheduled to undergo elective total or distal gastrectomy were assigned. During the surgery, IPA dissecting and exposing the origination point with photographs or video clips were required. The primary outcome was the origination of the IPA. Analysis of variance, χ~2 tests and Fisher's tests were used to analyze the differences between groups. The study is registered at Clinicaltrials.gov(No. NCT03071237).Results: Between May 8 and July 31, 2017, 429 patients were assigned for the study, and 419(97.7%) patients had the IPA dissected and recorded through photograph or video and were included in the primary outcome analysis. The median age was 62 years old, and 73.7% were male. Among the patients, 78.5% received laparoscopic surgery. Single IPA origination was identified in 398(95.0%) patients, including gastroduodenal artery(GDA) in154(36.8%) patients, anterior superior pancreaticoduodenal artery(ASPDA) in 130(31.0%) patients, and right gastroepiploic artery(RGEA) in 114(27.2%) patients. Fifteen(3.6%) patients were identified with multiple IPA and 6(1.4%) patients were identified as IPA absence. The differences in the distribution of surgical approach(P=0.003) and geographic area(P=0.030) were statistically significant. No difference was shown in sex, age,gastrectomy type, tumor location, and clinical T, N and M stage.Conclusions: Our study found that the IPA originates from GDA, ASPDA and RGEA in similar proportions.Laparoscopic surgery may be more helpful in dissection of the IPA than open surgery. | Rulin Miao Jianjun Qu Zhengrong Li Daguang Wang Jiang Yu Weidong Zang Yong Li Fenglin Liu Jian Zhang Wu Song Kai Ye Su Yan Wei Wang Shuangyi Ren Lu Zang Changqing Jing Li Zhang Kuan Wang Weihua Fu Lin Fan Bin Liang Gang Zhao Jun Cai Li Yang Jiaming Zhu Jun You Kun Yang Qingxing Huang Zhaojian Niu Ning Ning Xingfeng Qiu Gang Ji Feng Liang Hua Huang Chao Gao Fei Shan Shuangxi Li Yongning Jia Lianhai Zhang Xiangji Ying Yan Zhang Zhaode Bu Xiangqian Su Gang Zhao Ziyu Li Jiafu Ji | 2018 | Chinese Journal of Cancer Research2018，30，5： | 5 |
| 10 | Precise temporal regulation of Dux is important for embryo development显示文摘Dear Editor,Zygotic genome activation(ZGA)following fertilization is accomplished through a process termed the maternal-to-zygotic transition,during which the maternal RNAs and proteins are degraded and zygotic genome is transcriptionally activated.In mice,minor ZGA occurs from S phase of the zygote to G1 phase of the two-cell(2C)embryo,while major ZGA takes place during the middle-to-late 2C stage with a burst of transcription of totipotent cleavage stage-specific genes and retrotransposons. | Mingyue Guo Yanping Zhang Jianfeng Zhou Yan Bi Junqin Xu Ce Xu Xiaochen Kou Yanhong Zhao Yanhe Li Zhifen Tu Kuisheng Liu Jiaming Lin Peng Yang Shaorong Gao Yixuan Wang | 2019 | Cell Research2019，29，11： | 5 |
| 11 | Single-nucleus transcriptomic landscape of primate hippocampal aging显示文摘The hippocampus plays a crucial role in learning and memory,and its progressive deterioration with age is functionally linked to a variety of human neurodegenerative diseases.Yet a systematic profiling of the aging effects on various hippocampal cell types in primates is still missing.Here,we reported a variety of new aging-associated phenotypic changes of the primate hippocampus.These include,in particular,increased DNA damage and heterochromatin erosion with time,alongside loss of proteostasis and elevated inflammation.To understand their cellular and molecular causes,we established the first single-nucleus transcriptomic atlas of primate hippocampal aging.Among the 12 identified cell types,neural transiently amplifying progenitor cell(TAPC)and microglia were most affected by aging.In-depth dissection of gene-expression dynamics revealed impaired TAPC division and compromised neuronal function along the neurogenesis trajectory;additionally elevated pro-inflammatory responses in the aged microglia and oligodendrocyte,as well as dysregulated coagulation pathways in the aged endothelial cells may contribute to a hostile microenvironment for neurogenesis.This rich resource for understanding primate hippocampal aging may provide potential diagnostic biomarkers and therapeutic interventions against age-related neurodegenerative diseases. | Hui Zhang Jiaming Li Jie Ren Shuhui Sun Shuai Ma Weiqi Zhang Yang Yu Yusheng Cai Kaowen Yan Wei Li Baoyang Hu Piu Chan Guo-Guang Zhao Juan Carlos Izpisua Belmonte Qi Zhou Jing Qu Si Wang Guang-Hui Liu | 2021 | Protein & Cell2021，12，9： | 5 |
| 12 | The landscape of aging显示文摘Aging is characterized by a progressive deterioration of physiological integrity,leading to impaired functional ability and ultimately increased susceptibility to death.It is a major risk factor for chronic human diseases,including cardiovascular disease,diabetes,neurological degeneration,and cancer.Therefore,the growing emphasis on “healthy aging” raises a series of important questions in life and social sciences.In recent years,there has been unprecedented progress in aging research,particularly the discovery that the rate of aging is at least partly controlled by evolutionarily conserved genetic pathways and biological processes.In an attempt to bring full-fledged understanding to both the aging process and age-associated diseases,we review the descriptive,conceptual,and interventive aspects of the landscape of aging composed of a number of layers at the cellular,tissue,organ,organ system,and organismal levels. | Yusheng Cai Wei Song Jiaming Li Ying Jing Chuqian Liang Liyuan Zhang Xia Zhang Wenhui Zhang Beibei Liu Yongpan An Jingyi Li Baixue Tang Siyu Pei Xueying Wu Yuxuan Liu Cheng-Le Zhuang Yilin Ying Xuefeng Dou Yu Chen Fu-Hui Xiao Dingfeng Li Ruici Yang Ya Zhao Yang Wang Lihui Wang Yujing Li Shuai Ma Si Wang Xiaoyuan Song Jie Ren Liang Zhang Jun Wang Weiqi Zhang Zhengwei Xie Jing Qu Jianwei Wang Yichuan Xiao Ye Tian Gelin Wang Ping Hu Jing Ye Yu Sun Zhiyong Mao Qing-Peng Kong Qiang Liu Weiguo Zou Xiao-Li Tian Zhi-Xiong Xiao Yong Liu Jun-Ping Liu Moshi Song Jing-Dong J.Han Guang-Hui Liu | 2022 | Science China(Life Sciences)2022，65，12： | 4 |
| 13 | Effect of Al content on the reaction between Fe-10Mn-xAl(x=0.035wt%,0.5wt%,1wt%,and 2wt%)steel and CaO-SiO_(2)-Al_(2)O_(3)-MgO slag显示文摘The effect of Al content(0.035 wt%,0.5 wt%,1 wt%,and 2 wt%)on the composition change of steel and slag as well as inclusion transformation of high manganese steel after it has equilibrated with Ca O-Si O_(2)-Al_(2)O_(3)-Mg O slag was studied using the method of slag/steel reaction.The experimental results showed that as the initial content of Al increased from 0.035 wt%to 2 wt%,Al gradually replaced Mn to react with Si O_(2)in slag to avoid the loss of Mn due to the reaction;this process caused both Al_(2)O_(3)in slag and Si in steel to increase while Si O_(2)and Mn O in slag to reduce.In addition,the type of inclusions also evolved as the initial Al content increased.The evolution route of inclusions was Mn O→Mn O-Al_(2)O_(3)-Mg O→Mg O→Mn O-Ca O-Al_(2)O_(3)-Mg O and Mn O-Ca O-Mg O.The shape of inclusions evolved from spherical to irregular,became faceted,and finally transformed to spherical.The average size of inclusions presented a trend that was increasing first and then decreasing.The transformation mechanism of inclusions was explored.As the initial content of Al increased,Mg and Ca were reduced from top slag into molten steel in sequence,which consequently caused the transformation of inclusions. | Huixiang Yu Dexin Yang Jiaming Zhang Guangyuan Qiu Ni Zhang | 2022 | International Journal of Minerals,Metallurgy and Materials2022，29，2： | 4 |
| 14 | Effect of Zr on phase separation,mechanical and corrosion behavior of heterogeneous CoCrFeNiZr_(x) high-etropy alloy显示文摘CoCrFeNi high entropy alloy(HEA)has attracted extensive attention due to its excellent corrosion resistance,but the low strength limits its engineering application prospects.In order to develop CoCrFeNi based HEAs with high strength,ductility and corrosion resistance,the effects of Zr content on the microstructure,mechanical properties and corrosion resistance of heterogeneous CoCrFeNiZr_(x)(x=0,0.25,0.5 and 1)HEAs were investigated in this work.The results indicate that the increase of Zr content can significantly affect the phase stability of the alloy,and promote the formation of intermetallic compounds(Ni_(7)Zr_(2)and/or Laves phase)and the transformation of solid solution from face-centered cubic(FCC)structure(x=0,0.25 and 0.5)to body-centered cubic(BCC)structure(x=1).Reasonable control of the Zr content can endow the alloy excellent comprehensive properties.Especially,for CoCrFeNiZr_(0.25) alloy,composed of FCC matrix and a small amount of Ni_(7)Zr_(2)phases,the yield strength(~655 MPa)is increased by nearly four times higher than that of Zr-free alloy,and it also has good ductility(fracture stain>50%).Meanwhile,the corrosion resistance of CoCrFeNiZr_(0.25) alloy is better than that of SS304.The EIS results show that the addition of Zr reduces the stability of the passive film on the alloy,which can be related to the content of the beneficial oxide in the passive film and the thickness of the passive film through XPS analysis.Moreover,the work functions of different phases in CoCrFeNiZr_(x)alloys were obtained by firstprinciples calculations,which further confirmed the selective corrosion mechanism of the CoCrFeNiZr_(x) alloy combining the experimental results. | Wu Qi Wenrui Wang Xiao Yang Lu Xie Jiaming Zhang Dongyue Li Yong Zhang | 2022 | Journal of Materials Science & Technology2022，，14： | 3 |
| 15 | Corrosion Mechanism of 5083 Aluminum Alloy in Seawater Containing Phosphate显示文摘As a material with good corrosion resistance,5083 aluminum alloy has a great application prospect in marine environment.In this work,the corrosion characteristics of 5083 aluminum alloy in seawater containing phosphate were investigated with Potentiodynamic Polarization,Electrochemical Impedance Spectroscopy (EIS),Scanning Electron Microscope (SEM),Energy Dispersive Spectroscopy Analysis (EDSA),X-ray Photoelectron Spectroscopy (XPS) and Laser Confocal Microscope.The results indicated that the effects of phosphate in seawater were two-fold.Firstly,phosphate slightly accelerated the corrosion of 5083 in seawater in the early stage of corrosion.HPO_4~(2-)competed with OH~-in the adsorption process on the alloy surface,which weakened the contact between OH~-and Al~(3+)near the interface of the alloy,and inhibited the formation as well as the self-repair of the passive film,thus accelerating the activation dissolution process.Compared with the natural seawater,the charge transfer resistance of 5083 in the seawater containing phosphate decreased faster during the early stage of corrosion,and the corrosion current density i_(corr) was higher in seawater containing phosphate.On the other hand,the addition of phosphate would not affect the cluster distribution of the second phase of 5083 in seawater,but it changed the composition of the corrosion product layer and had an obvious inhibitory effect on the local corrosion of 5083 in seawater.After 16-day exposure,shallower and more sparsely distributed pits could be observed on the derusted surface of 5083 in the seawater containing phosphate,and the pitting coefficient in the seawater containing phosphate was significantly lower than that in natural seawater.The reduction of pitting tendency could be realized mainly through two ways.First,the HPO_4~(2-)adsorbed on the surface of the passive film in the early stage of corrosion and repeled the corrosive anions such as Cl~-.Second,phosphate participated in the construction of the Ca HPO_4 precipitation film,which acted as a barrier and protection. | WANG Jiaming YANG Haodong DU Min HOU Jian PENG Wenshan LIN Cunguo | 2021 | Journal of Ocean University of China2021，20，2： | 3 |

| 17 | Improving the resistance of the rice PTGMS line Feng39S by pyramiding blast,bacterial blight,and brown planthopper resistance genes显示文摘Knowledge of rice(Oryza sativa L.)genes and various DNA markers can be used in genomic breeding programs aimed at developing improved elite rice cultivars.We used an efficient genomic breeding approach to pyramid four resistance genes(Pi2,Xa23,Bph14,and Bph15)in the popular photoperiod-and thermosensitive genic male sterile(PTGMS)rice line Feng39S.We performed foreground selection for the target genes,followed by recombinant selection and background selection.This process reduced the sizes of the genomic segments harboring the target genes(566.8 kb for Pi2,1143.9 kb for Xa23,774.7 kb for Bph14,and 1574.9 kb for Bph15)and accelerated the recovery of the recurrent parent genome to proportions ranging from 98.77%to 99.16%,thus resulting in four near-isogenic lines.To assemble the four resistance genes in Feng39S,we performed a double-way cross combined with foreground and background selection to generate two improved lines of Feng39S(Pi2+Xa23+Bph14+Bph15)with a recurrent parent genome recovery of 98.98%.The two lines showed agronomic performance,grain quality,and fertility–sterility transition characteristics similar to those of the original Feng39S line.The newly developed PTGMS lines and corresponding hybrid combinations were resistant to various field blast isolates and seven representative isolates of bacterial blight.At the seedling stage,the lines also showed resistance against brown planthopper.This study provides an efficient and accurate genomic breeding approach for introducing desirable traits into PTGMS lines. | Dabing Yang Lizhong Xiong Tongmin Mou Jiaming Mi | 2022 | The Crop Journal2022，10，4： | 3 |
| 18 | A Fuzzy Hierarchical Strategy for Improving Frequency Regulation of Battery Energy Storage System显示文摘Battery energy storage systems(BESSs)can provide instantaneous support for frequency regulation(FR)because of their fast response characteristics.However,purely pursuing a better FR effect calls for continually rapid cycles of BESSs,which shortens their lifetime and deteriorates the operational economy.To coordinate the lifespan savings and the FR effect,this paper presents a control strategy for the FR of BESSs based on fuzzy logic and hierarchical controllers.The fuzzy logic controller improves the effect of FR by adjusting the charging/discharging power of the BESS with a higher response speed and precision based on the area control error(ACE)signal and the change rate of ACE in a non-linear way.Hierarchical controllers effectively reduce the life loss by optimizing the depth of discharge,which ensures that the state of charge(SOC)of BESS is always in the optimal operating range,and the total FR cost is the lowest at this time.The proposed method can achieve the optimal balance between ACE reduction and operational economy of BESS.The effectiveness of the proposed strategy is verified in a two-area power system. | Kaifeng Wang Ying Qiao Lirong Xie Jiaming Li Zongxiang Lu Huan Yang | 2021 | Journal of Modern Power Systems and Clean Energy2021，9，4： | 3 |
| 19 | Rearrangement on surface structures by boride to enhanced cycle stability for LiNi0.80Co0.15Al0.05O2 cathode in lithium ion batteries显示文摘The side reaction between the active material and liquid-electrolyte cause structural damage and particle pulverization is one of the important factors leading to the capacity decay of LiNi0.80Co0.15Al0.05O2(NCA)materials in Li ion batteries(LIBs).Surface modification is an effective strategy for NCA cathodes,which could alleviate the degradation associated with surface processes.Herein,a surface structure rearrangement of NCA cathode secondary particles was reported by in-situ forming a solid electrolyte LiBO2.The LiBO2 is beneficial for alleviating the stress during charge/discharge process,thereby slowing down the rate of cracks formation in the secondary particles,which facilitates the Li+de-intercalation as well as prevents penetration of the liquid-electrolyte into the interior of the particles.As a result,the surface structure rearrangement NCA(RS-NCA)delivers a high discharge capacity of 202.5 m Ah g^-1 at 0.1 C,and exhibits excellent cycle stability with discharge capacity retaining 148 m Ah g^-1 after 200 cycles at 2 C.This surface structure rearrangement approach provides a new viewpoint in designing high-performance high-voltage LIBs. | Shubiao Xia Wenjin Huang Xiang Shen Jiaming Liu Feixiang Cheng Jian-Jun Liu Xiaofei Yang Hong Guo | 2020 | Journal of Energy Chemistry2020，29，6： | 3 |
| 20 | Accumulation and Elimination Kinetics of 2-Methylisoborneol in Crucian Carp (Carassius carassius)显示文摘2-methylisoborneol(2-MIB) is a common, earthysmelling compound that causes taste and odor issues in aquaculture. To quantify the distribution, absorption, and depuration of 2-MIB in crucian carp(Carassius carassius), we detected and measured 2-MIB it via microwave, headspace solid-phase microextraction(HS-SPME), and gas chromatography before and after exposing fish to two different concentrations of 2-MIB(200 ng/L and 500 ng/L). The results showed that during the exposure time, the fish absorbed 2-MIB rapidly within 4 h. After exposure to 2-MIB for 120 h, the 2-MIB in gill and liver were rapidly removed. The processes of accumulation and elimination of 2-MIB in fish were investigated using the one-compartment kinetic model. The modeling results showed that the range of the uptake rate constant(k1) was 0.49-6.91. The range of the elimination rate constant(k2) was 0.05-0.27 and uptake rates were higher than elimination rates. The bioconcentration factor(BCF) was estimated according to the physicochemical properties of 2-MIB, and the bioaccumulation of 2-MIB in fish had a close correlation with the octanol/water partition coefficient(Kow). | YANG Meng HU Jiaming LIU Liming SHI Xiaotao LIU Guoyong ZUO Yanxia | 2019 | Wuhan University Journal of Natural Sciences2019，24，1： | 3 |
