1A 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
2Theoretical prediction,synthesis,and crystal structure determination of new MAX phase compound V2SnC显示文摘Guided by the theoretical prediction,a new MAX phase V2SnC was synthesized experimentally for the first time by reaction of V,Sn,and C mixtures at 1000°C.The chemical composition and crystal structure of this new compound were identified by the cross-check combination of first-principles calculations,X-ray diffraction(XRD),energy dispersive X-ray spectroscopy(EDS),and high resolution scanning transmission electron microscopy(HR-STEM).The stacking sequence of V2C and Sn layers results in a crystal structure of space group P63/mmc.The a-and c-lattice parameters,which were determined by the Rietveld analysis of powder XRD pattern,are 0.2981(0)nm and 1.3470(6)nm,respectively.The atomic positions are V at 4f(1/3,2/3,0.0776(5)),Sn at 2d(2/3,1/3,1/4),and C at 2a(0,0,0).A new set of XRD data of V2SnC was also obtained.Theoretical calculations suggest that this new compound is stable with negative formation energy and formation enthalpy,satisfied Born-Huang criteria of mechanical stability,and positive phonon branches over the Brillouin zone.It also has low shear deformation resistance c44(second-order elastic constant,cij)and shear modulus(G),positive Cauchy pressure,and low Pugh’s ratio(G/B=0.500<0.571),which is regarded as a quasi-ductile MAX phase.The mechanism underpinning the quasi-ductility is associated with the presence of a metallic bond.Qiang Xu Yanchun Zhou Haiming Zhang Anna Jiang Quanzheng Tao Jun Lu Johanna Rosén Yunhui Niu Salvatore Grasso Chunfeng Hu 2020Journal of Advanced Ceramics2020,9,4:8
3序列运算离散化过程中的误差成因及补偿显示文摘为了减少序列离散化过程导致的误差,提出几种概率补偿的方法。由误差的成因入手,分析了离散化过程的误差机理,将利用随机变量的概率分布函数离散化后所得序列,分别以修正公式、平均补偿法及比例补偿法进行补偿,推导出各种误差补偿方法下序列期望值及方差的误差估计公式。结果表明:经误差补偿后,算例中序列期望值误差下降为原误差的8%以下,而方差误差至少可降为原误差的91%。徐玮 康重庆 夏清 JIANG John N 2009清华大学学报(自然科学版)2009,,1:7
4Impact of chronic disease self-management programs on type 2 diabetes management in primary care显示文摘AIM: To assess the effectiveness of the Chronic Disease Self-Management Program(CDSMP) on glycated hemoglobin A1c(HbA1c) and selected self-reported measures.METHODS: We compared patients who received a diabetes self-care behavioral intervention, the CDSMP developed at the Stanford University, with controls whoreceived usual care on their HbA1c and selected self-reported measures, including diabetes self-care activities, health-related quality of life(HRQOL), pain and fatigue. The subjects were a subset of participants enrolled in a randomized controlled trial that took place at seven regional clinics of a university-affiliated integrated healthcare system of a multi-specialty group practice between January 2009 and June 2011. The primary outcome was change in HbA1c from randomization to 12 mo. Data were analyzed using multilevel statistical models and linear mixed models to provide unbiased estimates of intervention effects.RESULTS: Demographic and baseline clinical characteristics were generally comparable between the two groups. The average baseline HbA1c values in the CDSMP and control groups were 9.4% and 9.2%, respectively. Significant reductions in HbA1c were seen at 12 mo for the two groups, with adjusted changes around 0.6%(P < 0.0001), but the reductions did not differ significantly between the two groups(P = 0.885). Few significant differences were observed in participants' diabetes self-care activities. No significant differences were observed in the participants' HRQOL, pain, or fatigue measures.CONCLUSION: The CDSMP intervention may not lower HbA1c any better than good routine care in an integrated healthcare system. More research is needed to understand the benefits of self-management programs in primary care in different settings and populations.Samuel N Forjuoh Marcia G Ory Luohua Jiang Ann M Vuong Jane N Bolin 2014World Journal of Diabetes2014,5,3:6

10Detection of DC series arc in more electric aircraft power system based on optical spectrometry显示文摘Series arcing faults have been recognised as a hazardous phenomenon in the power system of more electric aircraft(MEA),especially with the increasing voltage level and power supply.Instead of the electrical method,the optical method can be used as an approach to detect arc fault with the advantages of fast response and immunity to electromagnetic interference.It is the basis of optical arc detection to determine the distribution spectrum range of direct current(DC)arc fault.Aiming at series arc optical detection in the MEA DC system,a DC series arc test platform was established to measure the series arc spectrum.The spectrum was disassembled though empirical mode decomposition to extract characteristic wavelengths of arc light and denoised by means of wavelet decomposition and reconstruction(wavelet transformation)to reduce equipment noise.To resolve the baseline drift,the baseline of the arc spectrum measured was calculated and corrected based on Savitzky−Golay.The experimental results indicate that there are several series arc characteristic spectra of the MEA DC system,including 309.3 and 324.5 nm in the ultraviolet range.Moreover,the arc spectrum with different metals,copper and aluminium,were contrasted,indicating the arc spectral behaviour is related to the melting/boiling point and chemical properties of the anode material.The measurement of the series arc spectrum makes it more effective to apply optical detection in the MEA discharging faults diagnosis.Jun Jiang Mingxin Zhao Zhe Wen Chaohai Zhang Ricardo Albarracín 2020High Voltage2020,5,1:3

13A Capillary Electrophoresis Detection Scheme for Water-soluble Vitamins Based on Luminol-BrO^- Chemiluminescence System显示文摘A novel chemiluminescence detection scheme has been developed for detecting water-soluble vitamins following capillary electrophoresis (CE) separation. This detection was based on the inhibitory effect of vitamins on the CL reaction between luminol and BrO- in basic aqueous solution. Detection of vitamins was accomplished with a boratebased background electrolyte at pH 9.2. The luminol was used as a component of the separation carrier electrolyte.Wei DENG, Wei Ping YANG, Zhu Jun ZHANG*, Hou Jiang ZHOU College of Chemistry and Materials Science, Shaanxi Normal University, Xi抋n 710062 2003Chinese Chemical Letters2003,14,2:2

17Sulfuric acid leaching kinetics of South African chromite显示文摘The sulfuric acid leaching kinetics of South African chromite was investigated. The negative influence of a solid product layer constituted of a silicon-rich phase and chromium-rich sulfate was eliminated by crushing the chromite and by selecting proper leaching conditions. The dimensionless change in specific surface area and the conversion rate of the chromite were observed to exhibit a proportional relationship. A modified shrinking particle model was developed to account for the change in reactive surface area, and the model was fitted to experimental data. The resulting model was observed to describe experimental findings very well. Kinetics analysis revealed that the leaching process is controlled by a chemical reaction under the employed experimental conditions and the activation energy of the reaction is 48 kJ ·mol–1.Qing Zhao Cheng-jun Liu Pei-yang Shi Bo Zhang Mao-fa Jiang Qing-song Zhang Ron Zevenhoven Henrik Saxén 2015International Journal of Minerals,Metallurgy and Materials2015,22,3:2
