剪切光束成像是一种非传统地基光学成像技术,在对位姿快速变化的目标成像时,为重构目标高分辨率清晰图像,其成像系统的回波数据采样速率仍不够快.本文提出一种五光束快速采样的图像重构方法,通过改变成像系统编码和解码方法,采用中心对称结构呈“十”字形排布的发射光束阵型,利用所提的快速图像重构算法,单次采样的回波数据所能重构的目标图像从1幅增加到8幅,快速抑制了重构图像的散斑效应.仿真结果表明,与传统三光束图像重构方法相比,获得相同质量图像所需的回波数据采样次数从20次减少至5次,大幅减少了回波数据采样次数,提高了回波数据采样速率.

In order to develop a rapid and reliable method for B. cereus genotyping, factors influencing PFGE results, including preparation of bacterial cells embedded in agarose, lysis of embedded cells, enzymatic digestion of intact genomic DNA, and electrophoresis parameters allowing for reproducible and meaningful DNA fragment separation, were controlled. Optimal cellular growth （Luria-Bertani agar plates for 12-18 h） and lysis conditions （4 h incubation with 500 μg/mL lysozyme） produced sharp bands on the gel.

Rare Metals 2022年第7期41卷 2491-2504页

作者： Yong-Fa Huang Rui Ding Dan-Feng Ying Yu-Xi Huang Tong Yan cai-Ni Tan xiu-juan Sun En-hui Liu Key Laboratory of Environmentally Friendly Chemistry and Applications of ministry of Education College of ChemistryXiangtan UniversityXiangtan 411105China

An innovative K+vacant ternary perovskite fluoride(K_(0.89)Ni_(0.02)Co_(0.03)Mn_(0.95)F_(3.0),KNCMF-3#)anode was designed for advanced Li-ion supercapattery(i.e.,Li-ion capacitors/batteries,LIC/Bs).Owing to the conversion/insertion dual mechanisms and fast pseudocapacitive con-trol dynamics,the KNCMF-3#electrode exhibits superior electrochemical performance,especially the excellent cycle performance(467%(229 mAh·g^(-1))/1000 cycles/2 A·g^(-1)).Moreover,the hybrid KNCMF-3#/reduced gra-phene oxide(rGO)electrode can further increase the electrochemical performance(217-97 mAh·g^(-1)/0.1-3.2 A·g^(-1),150%(197 mAh·g^(-1))/1000 cycles/2 A·g^(-1)).Also,a novel capacitor/battery cathode,activated carbon(AC)+LiFePO_(4)+graphene(AC+LFP+G),exhibits impres-sive performance(128-82 mAh·g^(-1)/0.1-3.2 A·g^(-1),84%/1000 cycles/2 A·g^(-1)).By the synergistic optimization of anode and cathode,the Li-ion supercapattery KNCMF-3#@rGO//AC+LFP+G demonstrates remarkable per-formance,for example,111.9-23.8 Wh·kg^(-1)/0.4-8.0 kW·kg^(-1)/82%/2000 cycles/5 A·g^(-1)/0-4 V,which is superior to KNCMF-3#//AC LICs,KNCMF-3#@rGO//AC LICs,KNCMF-3#//AC+LFP+G LIC/*** all,the novel Li-ion supercapattery idea adds a promising per-spective to develop advanced energy storage devices.

AIM: To investigate member 3a of Wingless-type MMTV integration site family (Wnt3a) expression in cancerous and surrounding tissues and the relationship between clinicopathologic features of hepatocellular carcinoma (HCC) and Wnt3a ***: Wnt3a expression and cellular distribution and clinicopathologic characteristics in cancerous tissue and matched surrounding tissues were analyzed in 80 HCC patients from January 2006 to August 2008 by tissue microarrays and immunohistochemistry. The overall and disease-free survival rates were estimated using the Kaplan-Meier method and compared with the log-rank test. The prognostic analysis was carried out with univariate and multivariate Cox regressions ***: The incidence of oncogenic Wnt3a expression in the cancerous group was up to 96.25% (77 of 80), which was significantly higher (χ2 = 48.818, P 2 = 20.211, P 2 = 8.467, P 2 = 12.957, P 2 = 22.960, P 2 = 15.469, P < 0.001).CONCLUSION: Oncogenic Wnt3a expression associated with HBV infection and cirrhotic liver might be an independent prognostic factor for HCC.

作为植物特有的转录因子，WUSCHEL同源异型盒(WUSCHEL-related homeobox, WOX)基因家族对植物的生长发育、组织器官发生和形成具有重要的调节作用。本研究利用生物信息学方法，在紫薇(Lagerstroemia indica)全基因组中鉴定出15个WOX基因家族成员，命名为LfiWOX1～LfiWOX15，分布在14条染色体上，家族成员间分子量和等电点有较大差异，亚细胞预测15个基因均定位于细胞核上。系统进化分析表明，15个基因共聚为3类，紫薇WOX家族成员中存在5个与拟南芥(Arabidopsis thaliana)、水稻(Oryza sativa)紧密相关的直系同源WOX成员，多个含有特定保守基序的WOX蛋白在进化树的同一分支上，所有家族成员都含有motif 1、motif 2和motif 5。WOX家族基因包含9种与植物生长发育、激素调控和逆境胁迫相关的顺式作用元件，不同成员含有不同的元件。qRT-PCR分析表明，与叶片相比，LfiWOX12、LfiWOX13、LfiWOX15在愈伤组织中表达量升高，是叶片中的1.5～1.9倍，其他基因在愈伤组织中表达量降低，是叶片中的0.1%～90%，说明LfiWOX12、LfiWOX13、LfiWOX15与愈伤形成相关。本研究为进一步研究紫薇WOX基因对愈伤诱导的调控提供了依据，为紫薇高效再生及遗传转化体系的建立提供参考。
