| 1 | The origin, diversification and adaptation of a major mangrove clade (Rhizophoreae) revealed by whole-genome sequencing显示文摘Mangroves invade some very marginal habitats for woody plants—at the interface between land and sea.Since mangroves anchor tropical coastal communities globally, their origin, diversification and adaptation are of scientific significance, particularly at a time of global climate change. In this study, a combination of single-molecule long reads and the more conventional short reads are generated from Rhizophora apiculata for the de novo assembly of its genome to a near chromosome level. The longest scaffold, N50 and N90 for the R. apiculata genome, are 13.3 Mb, 5.4 Mb and 1.0 Mb, respectively. Short reads for the genomes and transcriptomes of eight related species are also generated. We find that the ancestor of Rhizophoreae experienced a whole-genome duplication ~70 Myrs ago, which is followed rather quickly by colonization and species diversification. Mangroves exhibit pan-exome modifications of amino acid(AA) usage as well as unusual AA substitutions among closely related species. The usage and substitution of AAs, unique among plants surveyed, is correlated with the rapid evolution of proteins in mangroves. A small subset of these substitutions is associated with mangroves' highly specialized traits(vivipary and red bark) thought to be adaptive in the intertidal habitats. Despite the many adaptive features, mangroves are among the least genetically diverse plants, likely the result of continual habitat turnovers caused by repeated rises and falls of sea level in the geologically recent past. Mangrove genomes thus inform about their past evolutionary success as well as portend a possibly difficult future. | Shaohua Xu Ziwen He Zhang Zhang Zixiao Guo Wuxia Guo Haomin Lyu Jianfang Li Ming Yang Zhenglin Du Yelin Huang Renchao Zhou Cairong Zhong David E.

| 2 | Convergent adaptation of the genomes of woody plants at the land-sea interface显示文摘Sequencing multiple species that share the same ecological niche may be a new frontier for genomic studies.While such studies should shed light on molecular convergence,genomic-level analyses have been unsuccessful,due mainly to the absence of empirical controls.Woody plant species that colonized the global tropical coasts,collectively referred to as mangroves,are ideal for convergence studies.Here,we sequenced the genomes/transcriptomes of 16 species belonging in three major mangrove clades.To detect convergence in a large phylogeny,a CCS+model is implemented,extending the more limited CCS method(convergence at conservative sites).Using the empirical control for reference,the CCS+model reduces the noises drastically,thus permitting the identification of 73 convergent genes with Ptrue(probability of true convergence)>0.9.Products of the convergent genes tend to be on the plasma membrane associated with salinity tolerance.Importantly,convergence is more often manifested at a higher level than at amino-acid(AA)sites.Relative to>50 plant species,mangroves strongly prefer 4 AAs and avoid 5 others across the genome.AA substitutions between mangrove species strongly reflect these tendencies.In conclusion,the selection of taxa,the number of species and,in particular,the empirical control are all crucial for detecting genome-wide convergence.We believe this large study of mangroves is the first successful attempt at detecting genome-wide site convergence. | Ziwen He Shaohua Xu Zhang Zhang Wuxia Guo Haomin Lyu Cairong Zhong David EBoufford Norman CDuke The International Mangrove Consortium Suhua Shi | 2020 | National Science Review2020，7，6： | 3 |
| 3 | Operational optimization of a building-level integrated energy system considering additional potential benefits of energy storage显示文摘As a key component of an integrated energy system(IES),energy storage can effectively alleviate the problem of the times between energy production and consumption.Exploiting the benefits of energy storage can improve the competitiveness of multi-energy systems.This paper proposes a method for day-ahead operation optimization of a building-level integrated energy system(BIES)considering additional potential benefits of energy storage.Based on the characteristics of peak-shaving and valley-filling of energy storage,and further consideration of the changes in the system’s load and real-time electricity price,a model of additional potential benefits of energy storage is developed.Aiming at the lowest total operating cost,a bi-level optimal operational model for day-ahead operation of BIES is developed.A case analysis of different dispatch strategies verifies that the addition of the proposed battery scheduling strategy improves economic operation.The results demonstrate that the model can exploit energy storage’s potential,further optimize the power output of BIES and reduce the economic cost. | Sai Liu Cheng Zhou Haomin Guo Qingxin Shi Tiancheng E.Song Ian Schomer Yu Liu | 2021 | Protection and Control of Modern Power Systems2021，6，1： | 3 |
| 4 | Key technologies of roll forming automobile components with AHSS显示文摘Lightweight design is one of the development trends of the automobile industry.An effective way to achieve lightweight auto bodies is to use AHSS (advanced high strength steel) for the safety components of automobiles.This study has taken doorsill reinforcements made of martensite AHSS as the object,and performed research on the AHSS roll forming technologies and prototype development of typical asymmetric open components.By means of finite element analysis (FEA) and simulation,studies have been carried out on the springback and edge wave defects during AHSS roll forming,and an optimized process design has been achieved.The generation mechanisms of vertical bows,horizontal cambers,twists,pre-punched hole distortion and cut end flare have been analyzed,and solutions to these defects have been given.In addition,tesing of the roll forming process for AHSS has been conducted and typical samples with required dimensional accuracy have been manufactured.This study has provided technical support for the large-scale application of AHSS. | HAN Fei SHI Lei XIAO Hua JIANG Haomin LIU Jiying | 2013 | Baosteel Technical Research2013，7，1： | 2 |
| 5 | High-resolution characterization of hexagonal boron nitride coatings exposed to aqueous and air oxidative environments显示文摘六角形的硼氮化物(h-BN ) 被相信由于它的绝缘的性质比 graphene 把更好的钝化提供给金属性的表面,它便于堵住电子的流动,从而阻止流电的反应的出现。不过,当 h-BN-protected 材料暴露于水的环境时,这不能是盒子。在这个工作,我们分析了暴露于 H 2 O 2 和大气的条件。当暴露了到 H 2 O 2 。多层的 h-BN 提供了保护的好度。单层 h-BN 被发现也在空气气氛无效。甚至 10-15 层厚的 h-BN 栈不能完全在考虑下面保护金属的表面。由联合钻电子光谱学和第二等的离子团 spectrometry 技术,我们观察到氧能通过 h-BN 栈的谷物边界扩散到达金属性的底层。因为这个过程的散开的性质,一旦一个浸透的状态被到达,幸好,氧化区域没与时间增加。这成为多层(不单层) h-BN 一个合适的长期的氧化障碍。氧渗入不能被 X 光检查光电子光谱学观察。这种技术不能估计材料的更深的层的化学作文。因此,以前的报告,依靠了 XPS 分析 h-BN 和 graphene 的使钝化的性质,可能忽略了一些重要表面下的现象。在这研究获得的结果在水的媒介和暴露于空气环境的 h-BN-coated 金属的降级动力学提供新卓见进单音、多层的 h-BN 的使钝化的性质。 | Lanlan Jiang Na Xiao Bingru Wang Enric Grustan-Gutierrez Xu Jing Petr Babor Miroslav Kogbal Guangyuan Lu Tianru Wu Haomin Wang Fei Hui Yuanyuan Shi Bo Song Xiaoming Xie Mario Lanza | 2017 | Nano Research2017，10，6： | 2 |
| 6 | The Prevalence of Congenital Heart Disease among School-Age Children in China:A Meta-Analysis and Systematic Review显示文摘Objectives:To estimate the prevalence of Congenital Heart Disease(CHD)in school-age children,to identify the extent to which altitude affects the prevalence of the disease,and to examine trends in prevalence over time in China.Methods:Seven databases were systematically searched and last retrieved on September 10,2021 for all studies reporting the prevalence of CHD in children after 1970 in China,which were then divided into high and low altitude regions based on 2500 meters above sea level.The random-effected model was used to combine prevalence data and subgroups analysis.The baseline data of all cases and individuals were used for comparison to calculate the odds ratio(OR)for overall and different altitude prevalence.Results:A total of 12,926,083 individuals(aged 3-18 years),with 31,835 cases from 86 studies,were included in the analysis.The pooled CHD prevalence of total children was 4.69[95%confidence interval(CI):4.10 to 5.29]per 1000 children.Overall,temporal trends analysis indicated that the prevalence of CHD in children continuously decreased with time,from 6.19(95%CI:4.50 to 7.88)per 1000 children in 1976-1985 to 3.30(95%CI:2.49;4.38)per 1000 children in 2016-2021.The OR for the prevalence of CHD in children from high and low altitudes with baseline data was 2.84(95%CI:2.48 to 3.27)and 1.31(95%CI:1.13 to 1.53)(χ^(2)=53.89,p<0.01),respectively.The OR of the prevalence of CHD in male children compared to females was 0.60(95%CI:0.53 to 0.68)at high altitudes and 0.79(95%CI:0.71 to 0.89)at low altitudes.Among the seven most common subtypes,patent ductus arteriosus was the most common at high altitudes,while atrial septal defects were the most common at low altitudes.Conclusion:This study provides valuable insights for further disease prevention and etiological exploration.The overall decreasing trend in the prevalence of CHD in children over time may indicate a positive effect of perinatal management and treatment during infancy. | Shuqin Zhang Bin Zhang Jianying Wu Jin Luo Haomin Shi Jirong Qi Huilian Yang | 2023 | Congenital Heart Disease2023，18，2： | 0 |
| 7 | Expansion and adaptive evolution of the WRKY transcription factor family in Avicennia mangrove trees显示文摘Mangroves are adapted to intertidal zones,which present extreme environmental conditions.WRKYs are among the most prominent transcription factors(TFs)in higher plants and act through various interconnected networks to regulate responses to multiple abiotic stressors.Here,based on omic data,we investigated the landscape and evolutionary patterns of WRKYs in the main mangrove genus Avicennia.We found that both the number and the proportion of TFs and WRKYs in Avicennia species exceeded their inland relatives,indicating a signifcant expansion of WRKYs in Avicennia.We identifed 109 WRKY genes in the representative species Avicennia marina.Comparative genomic analysis showed that two recent wholegenome duplication(WGD)events played a critical role in the expansion of WRKYs,and 88%of Avicennia marina WRKYs(AmWRKYs)have been retained following these WGDs.Applying comparative transcriptomics on roots under experimental salt gradients,we inferred that there is high divergence in the expression of WGD-retained AmWRKYs.Moreover,we found that the expression of 16 AmWRKYs was stable between freshwater and moderately saline water but increased when the trees were exposed to high salinity.In particular,14 duplicates were retained following the two recent WGD events,indicating potential neo-and sub-functionalization.We also found that WRKYs could interact with other upregulated genes involved in signalling pathways and natural antioxidant biosynthesis to enhance salt tolerance,contributing to the adaptation to intertidal zones.Our omic data of the WRKY family in A.marina broadens the understanding of how a TF family relates to the adaptive evolution of mangroves. | Xiao Feng Guohong Li Weihong Wu Haomin Lyu Jiexin Wang Cong Liu Cairong Zhong Suhua Shi Ziwen He | 2023 | Marine Life Science & Technology2023，5，2： | 0 |
| 8 | An effective strategy for preparing transparent ceramics using nanorod powders based on pressure-assisted particle fracture and rearrangement显示文摘Achieving full densification of some ceramic materials,such as Y_(2)O_(3),without sintering aids by spark plasma sintering(SPS)is a great challenge when plastic deformation contributes limitedly to the densification as the yield stress of the material at an elevated temperature is higher than the applied sintering pressure.Herein,we demonstrate that particle fracture and rearrangement is an effective strategy to promote the densification during the pressure-assisted sintering process.Specifically,Y_(2)O_(3) nanocrystalline powders composed of nanorod and near-spherical particles were synthesized and sintered at various temperatures by the SPS.The results show that the relative density of the ceramics prepared by the nanorod powders is higher than the density of the ceramics from the near-spherical powders after 600℃ due to the fracture and rearrangement of the nanorods at low temperatures,which leads to the decrease of particle size and the increase of density and homogeneity.Based on this novel densification mechanism,ultrafine-grained Y_(2)O_(3) transparent ceramics with good optical and mechanical properties were fabricated successfully from the nanorod powders. | Zhangyi HUANG Yang SHI Yutong ZHANG Mao DENG Yi GUO Qingquan KONG Jianqi QI Benyuan MA Qingyuan WANG Haomin WANG | 2022 | Journal of Advanced Ceramics2022，11，12： | 0 |
