Achieving a highly robust zinc(Zn)metal anode is extremely important for improving the performance of aqueous Zn-ion batteries(AZIBs)for advancing“carbon neutrality”society,which is hampered by the uncontrollable growth of Zn dendrite and severe side reactions including hydrogen evolution reaction,corrosion,and passivation,***,an interlayer containing fluorinated zincophilic covalent organic framework with sulfonic acid groups(COF-S-F)is developed on Zn metal(Zn@COF-S-F)as the artificial solid electrolyte interface(SEI).Sulfonic acid group(-SO_(3)H)in COF-S-F can effectively ameliorate the desolvation process of hydrated Zn ions,and the three-dimensional channel with fluoride group(-F)can provide interconnected channels for the favorable transport of Zn ions with ion-confinement effects,endowing Zn@COF-S-F with dendrite-free morphology and suppressed side ***,Zn@COF-S-F symmetric cell can stably cycle for 1,000 h with low average hysteresis voltage(50.5 m V)at the current density of 1.5 m A cm^(-2).Zn@COF-S-F|Mn O_(2)cell delivers the discharge specific capacity of 206.8 m Ah g^(-1)at the current density of 1.2 A g^(-1)after 800 cycles with high-capacity retention(87.9%).Enlightening,building artificial SEI on metallic Zn surface with targeted design has been proved as the effective strategy to foster the practical application of high-performance AZIBs.

Histamine is a neurotransmitter and neuromodulator in the central nervous system,which plays its function through binding with diferent histamine receptors,such as H_(1)receptor(H_(1)R),H_(2)receptor(H_(2)R),H_(3)receptor(H_(3)R),and H_(4)receptor(H_(4)R)[1,2].Although both H_(1)R and H_(2)R,as post-synaptic receptors,are expressed in most brain areas,they captured different attention from scientists.H,R is well stud-ied and believed to play critical roles in many physiological and pathological processes,including sleep and wakefulness.

兔肝球虫和大肠杆菌是家兔养殖中常见且危害较大的疾病。为了确定河南省某兔场家兔腹泻并大规模死亡的病原,实验室对兔场发病兔进行病理剖检和寄生虫检测,采集组织进行病原菌的分离鉴定及药敏试验。结果显示:发病兔粪样检测到的球虫数量较少,未达到肠球虫感染标准;病理剖检发现个别兔肝脏有白色条形结节状结构;所有剖检兔胆汁镜检可见大量球虫卵囊;细菌分离培养得到一株革兰氏阴性杆状可疑致病菌,其eae基因序列扩增片段为833 bp,与大肠杆菌MN208178.1相似性为99.65%;经药敏测定发现分离得到的大肠杆菌同时对多黏菌素B、丁胺卡那、氨苄西林、头孢哌酮4种药物敏感,对其他药物有不同程度的耐药性。根据以上试验结果,导致此次兔场大规模发病死亡的主要原因是肝球虫和其继发的大肠杆菌混合感染。研究结果可为家兔养殖过程中肝球虫和大肠杆菌混合感染的诊断以及临床用药提供参考。

An Open Source Toolkit for Identifying Comparative Space-time Research Questions

Chinese Geographical Science 2014年第3期24卷 348-361页

Comparative space-time thinking lies at the heart of spatiotemporally integrated social sciences. The multiple dimensions and scales of socioeconomic dynamics pose numerous challenges for the application and evaluation of public policies in the comparative context. At the same time, social scientists have been slow to adopt and implement new spatiotemporally explicit methods of data analysis due to the lack of extensible software packages, which becomes a major impediment to the promotion of spatiotemporal thinking. The proposed framework will address this need by developing a set of research questions based on space-time-distributional features of socioeconomic datasets. The authors aim to develop, evaluate, and implement this framework in an open source toolkit to comprehensively quantify the changes and level of hidden variation of space-time datasets across scales and dimensions. Free access to the source code allows a broader community to incorporate additional advances in perspectives and methods, thus facilitating interdisciplinary collaboration. Being written in Python, it is entirely cross-platform, lowering transmission costs in research and education.

Topological Disk Mesh Morphing Based on Area-Preserving Parameterization

引用

Wuhan University Journal of Natural Sciences 2018年第3期23卷 201-209页

作者： CHEN Cailing SU Kehua zhu xinyan School of Computer Wuhan University Wuhan 430072Hubei China State Key Laboratory of Information Engineering in Surveying Mapping and Remote Sensing Wuhan UniversityWuhan 430072 Hubei China

Mesh morphing is a technique which gradually deforms a mesh into another one. Mesh parameterization, a powerful tool adopted to establish the one-to-one correspondence map between different meshes, is of great importance in 3 D mesh morphing. However, current parameterization methods used in mesh morphing induce large area distortion, resulting in geometric information loss. In this paper, we propose a new morphing approach for topological disk meshes based on area-preserving parameterization. Conformal mapping and M？bius transformation are computed firstly as rough alignment. Then area preserving parameterization is computed via the discrete optimal mass transport map. Features are exactly aligned through radial basis functions. A surface remeshing scheme via Delaunay refinement algorithm is developed to create a new mesh connectivity. Experimental results demonstrate that the proposed method performs well and generates high-quality morphs.

目的探讨异佛莱心苷对四氯化碳(carbon tetrachloride,CCl 4)所致小鼠肝纤维化的抑制作用。方法将24只C57BL6J小鼠随机分为空白对照组、肝纤维化模型组、异佛莱心苷治疗组和水飞蓟素治疗组,每组6只。肝纤维化模型组、异佛莱心苷治疗组和水飞蓟素治疗组通过腹腔注射CCl 4建立肝纤维化模型,每周3次,共12周。从第6周起,异佛莱心苷治疗组小鼠每日灌胃异佛莱心苷(10 mmol/L),水飞蓟素治疗组小鼠每日灌胃水飞蓟素100 mg/kg,连续给药6周。采集各组小鼠静脉血,血清检测丙氨酸氨基转移酶(alanine aminotransferase,ALT)和天冬氨酸氨基转移酶(aspartate aminotransferase,AST);肝组织做HE染色、Masson染色和天狼星红染色;组织免疫荧光检测TGF-β1的表达;ELISA法检测各组血清中TGF-β1、IL-1β、IL-6和TNF-α含量;Western印迹法检测肝脏AKT/Smad2通路变化。结果肝纤维化模型组血清ALT和AST较空白对照组显著升高(P<0.05),异佛莱心苷治疗组和水飞蓟素治疗组小鼠血清ALT和AST均较肝纤维化模型组显著降低(P<0.05),小鼠肝重和肝重/体重也较肝纤维化模型组显著降低(P<0.05)。两组小鼠肝组织病理学形态较肝纤维化模型组有一定程度的改善。组织免疫荧光显示肝纤维化模型组TGF-β1表达较空白对照组升高;异佛莱心苷和水飞蓟素治疗后肝脏TGF-β1表达降低。异佛莱心苷治疗组和水飞蓟素治疗组炎症指标(TGF-β1、IL-1β、IL-6和TNF-α)较肝纤维化模型组显著降低(P<0.05)。Western印迹法结果显示肝纤维化后p-Smad2、Smad2和p-AKT蛋白表达显著升高(P<0.05),但异佛莱心苷治疗后肝脏组织中AKT/Smad2表达下降(P<0.05),提示该通路异常激活被抑制。结论异佛莱心苷对小鼠肝纤维化有抑制作用,其作用机制可能与抑制炎症反应和AKT/Smad2通路有关。
