4Water in the upper mantle and deep crust of eastern China: concentration, distribution and implications显示文摘Understanding the concentration and distribution of water in the Earth's mantle plays a substantial role in studying its chemical, physical and dynamic processes. After a decade of research, a comprehensive dataset of water content in upper-mantle samples has been built for eastern China, which is now the only place with water-content data from such diverse types of natural samples, and provides an integrated picture of the water content and its distribution in the upper mantle at a continental scale. The main findings include the following:(i) the temporal heterogeneity of the water content in the lithospheric mantle from early Cretaceous(~120 Ma) to Cenozoic(<40 Ma) was tightly connected with the stability of the North China Craton(from its destruction to its consolidation);(ii) the heterogeneous water content in the Cenozoic lithospheric mantle beneath different blocks of eastern China was not only inherited from tectonic settings from which they came, but was also affected later by geological processes they experienced;(iii) the distinct water content between the lowermost crust and lithospheric mantle of eastern China and its induced rheological contrast at the base of the crust indicate that the continental crust–mantle boundary could behave either in a coupled or decoupled manner beneath different areas and/or at different stages;(iv) the alkali basalts of eastern China demonstrate a heterogeneous distribution of water content in the mantle;local and regional comparisons of the water content between the lithospheric mantle and basalts' source indicate that the Cenozoic alkali basalts in eastern China were not sourced from the lithospheric mantle.Instead, the inferred high water contents in the mantle sources suggest that the Cenozoic eastern China basalts were likely sourced from the mantle transition zone(MTZ); and(v) both oceanic and continental crusts may carry a certain amount of water back into the deep mantle of eastern China by plate subduction.Such recycled crustal materials have not only created a local water-rich zone, but have also introduced crustal geochemical signatures into the mantle, both accounting for crustal geochemical imprints in the intra-plate magmatic rocks of eastern China.Qun-Ke Xia Jia Liu István Kovács Yan-Tao Hao Pei Li Xiao-Zhi Yang Huan Chen Ying-Ming Sheng 2019National Science Review2019,6,1:16

6A Chromosome-Level Genome Assembly of Garlic (Allium sativum) Provides Insights into Genome Evolution and Allicin Biosynthesis显示文摘Garlic,an economically important vegetable,spice,and medicinal crop,produces highly enlarged bulbs and unique organosulfur compounds.Here,we report a chromosome-level genome assembly for garlic,with a total size of approximately 16.24 Gb,as well as the annotation of 57561 predicted protein-coding genes,making garlic the first Allium species with a sequenced genome.Analysis of this garlic genome assembly reveals a recent burst of transposable elements,explaining the substantial expansion of the garlic genome.We examined the evolution of certain genes associated with the biosynthesis of allicin and inulin neoseries-type fructans,and provided new insights into the biosynthesis of these two compounds.Furthermore,a large-scale transcriptome was produced to characterize the expression patterns of garlic genes in different tissues and at various growth stages of enlarged bulbs.The reference genome and large-scale transcriptome data generated in this study provide valuable new resources for research on garlic biology and breeding.Xiudong Sun Siyuan Zhu Ningyang Li Yi Cheng Jing Zhao Xuguang Qiao Li Lu Shiqi Liu Yanzhou Wang Chan Liu Benping Li Wu Guo Shuang Gao Zemao Yang Fu Li Zheng Zeng Qing Tang Yupeng Pan Mengjiao Guan Jian Zhao Xiaomi ng Lu Huanwe n Meng Zhenlin Han Chun she ng Gao Wenkai Jiang Xing Zhao Shilin Tian Jianguang Su Zhihui Cheng Touming Liu 2020Molecular Plant2020,13,9:14
7Geochemistry of the subduction-related magmatic rocks in the Dahong Mountains, northern Hubei Province--Constraint on the existence and subduction of the eastern Mianlüe oceanic basin显示文摘The existence and subduction of the eastern Mianl黣 oceanic basin in the south Qinling belt are keys to understand the Qinling orogen. Based on geological mapping, several volcanic slices have been identified in Tumen, Zhoujiawan, Xiaofu and Yuantan areas, which distribute in the northern margin of the Dahong Mountains (DHM), and thrust into the Sanli-gang-Sanyang fault. These slices consist mainly of diabases, basaltic-andesitic lavas, pyroclastic rocks and a minor tuff. The geochemistry of the basalts, andesites,and diabases is characterized by depleting in Nb and Ta, enriching in Th and LILE (e.g.K, Rb, Ba), and undifferentiating in HFSE. These geochemical characteristics suggest that the original magma of these rocks was derived from a mantle wedge above a subduction zone, and formed in an island-arc setting in Carboniferous-early Triassic. Comparing with the ophiolites and island-arc volcanic rocks in Mianxian-Leyang area to the west, it is reasonable to consider that there had been an oceanic basin connecting with the Mianle ancient ocean to the westward, distributing along the south edge of the Tongbai-Dabie block. In view of the ophiolite in Huashan area and these island-arc volcanic rocks along the north of the Dahong Mountains, it is suggested that there had been a plate tectonic evolutionary history with oceanic basin rifting and subduction in this region.DONG Yunpeng, ZHANG Guowei, ZHAO Xia, YAO Anping & LIU Xiaoming The Key Laboratory of Continental Dynamics, Ministry of Education, Department of Geology, Northwest University, Xi抋n 710069,China 2004Science China Earth Sciences2004,47,4:12

12Development of Soybean EST-SSR Markers and Their Use to Assess Genetic Diversity in the Subgenus Soja显示文摘Developing expressed sequence tag-derived SSR(EST-SSR)markers is imperative in genetic research.In this paper,we reported 37 EST-SSR markers which were developed from 286 unigenes obtained from soybean cDNA library.Among the 286 markers designed for the 4 accessions of Glycine max and 6 of its wild progenitor(G.soja)within the subgenus Soja,209 markers amplified DNA fragments,taking 73.1% and 37 markers appeared to be polymorphic,which was 12.9% of the total.The 37 loci detected a total of 142 alleles,while the PIC values varied from 0.194 to 0.794.Both the number of alleles per locus and PIC value were significantly related to the SSR motif.Six EST-SSR loci may be fixed for different alleles between G.max and G.soja since they were particularly polymorphic among the 6 G.soja accessions.A neighbor-joining tree placed the G.max accessions together as a group within the G.soja,though the average genetic distance among G.soja accessions was much higher.These new EST-SSRs markers will be useful for genetic diversity analysis,genetic mapping construction and gene discovery in Soja subgenus.LIU Yu-lin LI Ying-hui ZHOU Guo-an Uzokwe N CHANG Ru-zhen CHEN Shou-yi QIU Li-juan 2010Agricultural Sciences in China2010,9,10:6

14Machine learning in orthopaedic surgery显示文摘Artificial intelligence and machine learning in orthopaedic surgery has gained mass interest over the last decade or so.In prior studies,researchers have demonstrated that machine learning in orthopaedics can be used for different applications such as fracture detection,bone tumor diagnosis,detecting hip implant mechanical loosening,and grading osteoarthritis.As time goes on,the utility of artificial intelligence and machine learning algorithms,such as deep learning,continues to grow and expand in orthopaedic surgery.The purpose of this review is to provide an understanding of the concepts of machine learning and a background of current and future orthopaedic applications of machine learning in risk assessment,outcomes assessment,imaging,and basic science fields.In most cases,machine learning has proven to be just as effective,if not more effective,than prior methods such as logistic regression in assessment and prediction.With the help of deep learning algorithms,such as artificial neural networks and convolutional neural networks,artificial intelligence in orthopaedics has been able to improve diagnostic accuracy and speed,flag the most critical and urgent patients for immediate attention,reduce the amount of human error,reduce the strain on medical professionals,and improve care.Because machine learning has shown diagnostic and prognostic uses in orthopaedic surgery,physicians should continue to research these techniques and be trained to use these methods effectively in order to improve orthopaedic treatment.Simon P Lalehzarian Anirudh K Gowd Joseph N Liu 2021World Journal of Orthopedics2021,12,9:4

18Source identification, contamination status and health risk assessment of heavy metals from road dusts in Dhaka, Bangladesh显示文摘In this study, concentrations of Cr, Mn, Ni, Cu, Zn, Cd and Pb were determined in road dusts collected from different locations in Dhaka to assess source, contamination status and health risk. Energy-dispersive X-ray fluorescence spectroscopy and energy-dispersive X-ray spectroscopy were used to determine Cr, Mn, Ni, Cu, Zn, Cd and Pb and their mean concentrations were 162.27 ± 29.46, 721.18 ± 180.14, 35.65 ± 12.55, 104.56 ± 128.33, 515.32 ± 321.90,BDL, and 342.82 ± 591.20 mg/kg, respectively. Among the heavy metals, highest concentrations of Cu, Zn and Pb were found at urban sites-7(municipal waste dumping) and 8(medical waste incineration). Highest concentration of Cr followed by Cu and Zn was found at site-5(Tejgaon, urban). Principal component analysis revealed that anthropogenic activities are the potential sources for Cr, Ni, Cu, Zn and Pb while earth crust for Mn. Pollution index and pollution load index results suggested that all the sites were contaminated and/or degraded by Cr, Cu, Zn and Pb except sites-9(urban), 10(sub-urban), 11(rural) while sites-7 and 8(urban) were extremely degraded. For noncarcinogenic health risk, hazard quotient values for dermal were higher compared to that of inhalation/ingestion. Though hazard index values were less than 1 at all the sites, these were at least one order of magnitude higher for children group than that of adult group, thus the children group may face more noncarcinogenic health risk at sites -7 and 8. Values of incremental lifetime cancer risk were from 10to 10showed no carcinogenic health risk by road dusts contaminated with the heavy metals.Aklima Nargis Ahsan Habib Md Nazrul Islam Kai Chen Md Shafiqul Islam Sarker A N M Al-Razee Wenbin Liu Guorui Liu Minggang Cai 2022Journal of Environmental Sciences2022,34,11:3
19PDX1.1-dependent biosynthesis of vitamin B6 protects roots from ammonium-induced oxidative stress显示文摘Despite serving as a major inorganic nitrogen source for plants,ammonium causes toxicity at elevated con-centrations,inhibiting root elongation early on.While previous studies have shown that ammonium-inhibited root development relates to ammonium uptake and formation of reactive oxygen species(ROS)in roots,it remains unclear about the mechanisms underlying the repression of root growth and how plants cope with this inhibitory effect of ammonium.In this study,we demonstrate that ammonium-induced apo-plastic acidification co-localizes with Fe precipitation and hydrogen peroxide(H_(2)O_(2))accumulation along the stele of the elongation and differentiation zone in root tips,indicating Fe-dependent ROS formation.By screening ammonium sensitivity in T-DNA insertion lines of ammonium-responsive genes,we identified PDX1.1,which is upregulated by ammonium in the root stele and whose product catalyzes de novo biosyn-thesis of vitamin B6.Root growth of pdx1.1 mutants is hypersensitive to ammonium,while chemical complementation or overexpression of PDX1.1 restores root elongation.This salvage strategy requires non-phosphorylated forms of vitamin B6 that are able to quench ROS and rescue root growth from ammo-nium inhibition.Collectively,these results suggest that PDX1.1-mediated synthesis of non-phosphorylated B6 vitamers acts as a primary strategy to protect roots from ammonium-dependent ROS formation.Ying Liu Rodolfo A.Maniero Ricardo F.H.Giehl Michael Melzer Priscille Steensma Gabriel Krouk Teresa B.Fitzpatrick Nicolaus von Wirén 2022Molecular Plant2022,15,5:3
20汽车动力系离合器接合抖振和粘一滑的分析和仿真显示文摘研究分析了离合器接合的抖振和粘一滑以及用数字来检验这些现象的影响系数。为具有汽车变速箱装置的动力系带打滑离合的4自由度(4DOF)的扭振系统开发了一个模型。进行稳态分析表明该离合器的抖振与摩擦系数和斜率有关,并用数字仿真加以证实。开发了模拟粘一滑的一种算法,并用于数字仿真,它表明了由于离合器压力波动,离开接合的抖振和外载荷变动将增加了粘一滑的可能性。由2档换到3档的数字仿真证明,根据离合器接合时作用压力波动,离开接合抖振和外载荷波动发生粘一滑可能增大,而随作用压力倾斜到啮合点发生粘一滑可能性明显减少。A.
