| 1 | A critical survey of technologies of large offshore wind farm integration: summary, advances, and perspectives显示文摘Offshore wind farms(OWFs)have received widespread attention for their abundant unexploited wind energy poten-tial and convenient locations conditions.They are rapidly developing towards having large capacity and being located further away from shore.It is thus necessary to explore effective power transmission technologies to connect large OWFs to onshore grids.At present,three types of power transmission technologies have been proposed for large OWF integration.They are:high voltage alternating current(HVAC)transmission,high voltage direct current(HVDC)transmission,and low-frequency alternating current(LFAC)or fractional frequency alternating current transmission.This work undertakes a comprehensive review of grid connection technologies for large OWF integration.Compared with previous reviews,a more exhaustive summary is provided to elaborate HVAC,LFAC,and five HVDC topologies,consisting of line-commutated converter HVDC,voltage source converter HVDC,hybrid-HVDC,diode rectifier-based HVDC,and all DC transmission systems.The fault ride-through technologies of the grid connection schemes are also presented in detail to provide research references and guidelines for researchers.In addition,a comprehensive evalu-ation of the seven grid connection technologies for large OWFs is proposed based on eight specific indicators.Finally,eight conclusions and six perspectives are outlined for future research in integrating large OWFs. | Bo Yang Bingqiang Liu Hongyu Zhou Jingbo Wang Wei Yao Shaocong Wu Hongchun Shu Yaxing Ren | 2022 | Protection and Control of Modern Power Systems2022，7，1： | 4 |
| 2 | Progress on major genes for high fecundity in ewes显示文摘The existence of major genes affecting fecundity in sheep flocks throughout the world has been demonstrated.Three major genes whose mutations can increase ovulation rate have been discovered,and all related to the transforming growth factorβ(TGF-β)superfamily.The mutant FecB of bone morphogenetic protein receptor 1B(BMPR1B)has an additive effect on ovulation rate.Six mutations(Fec^(XI),Fec^(XH),Fec^(XG),Fec^(XB),Fec^(XL),Fec^(XR))of bone morphogenetic protein 15(BMP15)related with fertility have been identified that share the same mechanism.All the mutants can increase ovulation rate in heterozygotes and cause complete sterility in homozygotes.Homozygous ewes with two new mutations(FecX^(Gr),FecX^(O))of BMP15 had increased ovulation rate without causing sterility.There are five mutations in growth differentiation factor 9(GDF9)associated with sheep prolificacy where FecG^(E) and FecG^(F) have additive an effect on ovulation rate and litter size.The newly identifiedβ-1,4-N-acetylgalactosaminyltransferase 2(B4GALNT2)gene of FecL is proposed as a new mechanism of ovulation rate regulation in sheep.Woodlands is an X-linked maternally imprinted gene which increases ovulation rate.In addition,several putative major genes need to be verified.This review is focused on the identification of the mutations and mechanisms whereby the major genes affecting ovulation rate. | Qiuyue LIU Zhangyuan PAN Xiangyu WANG Wenping HU Ran DI Yaxing YAO Mingxing CHU | 2014 | Frontiers of Agricultural Science and Engineering2014，1，4： | 3 |

| 5 | ADDITION OF LITHIUM CARBONATE TO THE ANODE PASTE USED IN SODERBERG CELLS显示文摘Laboratory studies showed that addition of about 0.5%(in mass)Li_(2)CO_(3).to the anode used in an aluminium electrolysis cell gave increased wetting of the anode by the cryolite-alumina melt,increased critical current density and reduced anodic overvoltage.The lithium carbonate then acted as a catalyst for the oxidation reaction between the anode carbon and the oxide-containing ions in the melt.Anode paste containing lithium carbonate has been employed in Chinese aluminium smelters with 62 kA HSS cells.This lead to improved current efficiency,reduced cell voltage and energy consumption,as well as fewer anode effects per day. | Qiu Zhuxian Sun Ting Yue Yaxing Yao Kwangtsung Li Qingfeng Grjotheim Kai Kvande Halvor | 1996 | Transactions of Nonferrous Metals Society of China1996，6，1： | 0 |
| 6 | Efficient derivation of extended pluripotent stem cells from NOD-scid II2rg-/-mice显示文摘Recently we have established a new culture condition enabling the derivation of extended pluripotent stem(EPS)cells,which,compared to conventional pluripotent stem cells,possess superior developmental potential and germline competence.However,it remains unclear whether this condition permits derivation of EPS cells from mouse strains that are refractory or non-permissive to pluripotent cell establishment.Here,we show that EPS cells can be robustly generated from non-permissive NOD-sc/d Il2rg 1 mice through de novo derivation from blastocysts.Furthermore,these cells can also be efficiently generated by chemical reprogramming from embryonic NOD-sc/d II2rg-/-fibroblasts.NOD-sc/d II2rg-/-EPS cells can be expanded for more than 20 passages with genomic stability and can be genetically modified through gene targeting.Notably,these cells contribute to both embryonic and extraembryonic lineages in vivo.More importantly,they can produce chimeras and integrate into the E13.5 genital ridge.Our study demonstrates the feasibility of generating EPS cells from refractory mouse strains,which could potentially be a general strategy for deriving mouse pluripotent cells.The generation of NOD-sc/d II2rg-/-Yaqin Du and Ting Wang contributed equally to this work.Electronic supplementary material The online version of this article(http://gffzzd3cc09b8251d45dfs60okvk9pop5k6bwc.ffgz.tsg.suse.edu.cn/10.1007/s13238-018-0558-z)contains supplementary material,which is available to authorized users.EPS cell lines permits sophisticated genetic modification in NOD-scid II2rg-/-mice,which may greatly advance the optimization of humanized mouse models for biomedical applications. | Yaqin Du Ting Wang Jun Xu Chaoran Zhao Haibo Li Yao Fu Yaxing Xu Liangfu Xie Jingru Zhao Weifeng Yang Ming Yin Jinhua Wen Hongkui Deng | 2019 | Protein & Cell2019，10，1： | 0 |
