Seawater electrolysis is a highly promising method to produce high energy density hydrogen,especially in dry areas that have scarce freshwater ***,application of seawater electrolysis is confronted by two major problems associated with catalysts employed for the anodic oxygen evolution reaction （OER） including the competitive hypochlorite evolution reaction（HCER） and strong chloridion （Cl–） triggered *** studies aimed at overcoming these problems,a facile method has been developed to synthesize a homologous CoS2heterojunction as an OER *** to a difference in work functions at the interface and increased electron density,this material has directed electron transfer and strong chloridion repulsion properties,*** have shown that CoS2achieves low overpotentials of 289 and 322 mV at 10 mA cm-2current density in respective alkaline （1 M KOH） and alkaline simulated seawater ***,the outstanding stability of CoS2is reflected in a negligible decline in activity during promotion of the OER for 100 *** of density functional theory calculations reveal that the homologous CoS2heterojunction promotes directed electron transport for optimizing adsorption/desorption of reactive species and heightens the Cl-adsorption energy for strongly repulsing Cl-,phenomena that enhance OER performance in alkaline simulated seawater.

该研究基于GPER2／MAPK／sTAT1轴研究少腹逐瘀汤治疗子宫内膜异位症痛经分子机制。采用异位移植造EMT模型；HE染色观察各组大鼠灌药治疗后宫腔组织病理变化；EEISA实验检测大鼠宫腔组织中TNF-α，IL一6的含量变化；qPCR检测宫腔组织中神经激肽受体（NK1）、GPER mRNA表达；Western blot法检测官腔组织中MAPK，STAT1蛋白含量。结果显示，在病理水平上，与模型组相比，少腹逐瘀汤可显著改善异位宫腔组织炎症情况，导致异位宫腔组织中浸润的炎症细胞减少，抑制血管生成，使宫腔组织壁变薄，阻止其生长，这种抑制表现出一定的浓度依赖性。在分子水平上，少腹逐瘀汤降低宫腔组织中炎症相关因子TNF-α，IL-6含量，减少NK1，GPER2 mRNA的相对表达量，并导致宫腔组织中MAPK和STAT1蛋白表达降低。综上可知少腹逐瘀汤可有效抑制异位宫腔组织中GPER2 mRNA以及MAPK，STAT1蛋白的表达，降低TNF-α，IL-6相关炎症因子的含量以及疼痛介质NK1 mRNA的含量从而减轻子宫内膜异位症患者炎症疼痛。

Sporadic E(Es)layers in the ionosphere are characterized by intense plasma irregularities in the E region at altitudes of 90-130 *** they can significantly influence radio communications and navigation systems,accurate forecasting of Es layers is crucial for ensuring the precision and dependability of navigation satellite *** this study,we present Es predictions made by an empirical model and by a deep learning model,and analyze their differences comprehensively by comparing the model predictions to satellite RO measurements and ground-based ionosonde *** deep learning model exhibited significantly better performance,as indicated by its high coefficient of correlation(r=0.87)with RO observations and predictions,than did the empirical model(r=0.53).This study highlights the importance of integrating artificial intelligence technology into ionosphere modelling generally,and into predicting Es layer occurrences and characteristics,in particular.

In recent years, machine learning (ML) techniques have been shown to be effective in accelerating the development process of optoelectronic devices. However, as"black box"models, they have limited theoretical interpretability. In this work, we leverage symbolic regression (SR) technique for discovering the explicit symbolic relationship between the structure of the optoelectronic Fabry-Perot (FP) laser and its optical field distribution, which greatly improves model transparency compared to ML. We demonstrated that the expressions explored through SR exhibit lower errors on the test set compared to ML models, which suggests that the expressions have better fitting and generalization capabilities.

Photoactive complexes of nonprecious transition metals, mainly including those in the first-row and partially the second-row of the Periodic table of elements, have received increasing attention in view of their low cost and long-term sustainability. They are recognized as promising alternatives to noble transition metal complex congeners that have been extensively studied in optoelectronic devices, artificial photosynthesis, photocatalysis, biodiagnostics, and therapeutics, etc. This review is devoted to a comprehensive summary on the classical and recent advances on photoactive nonprecious transition metal complexes, including photoactive Zr, V, Cr, Mo, and W complexes, Mn complexes and hybrids, Fe, Co, Ni, and Cu complexes, and Zn and Cd complexes and hybrids. A particular focus is given on the molecular design, modulation of photophysical and photochemical properties, and applications of the representative and lately-developed nonprecious metal complexes. In addition, a perspective on the future development in this field is provided at the end of this review.

中国作为全球系统重要性国家,外部环境变化必然冲击国内债券市场,投资者情绪起落传递金融风险.本文选取2007—2022年中国非金融上市公司发行债券数据验证地缘政治风险对企业融资成本的影响.研究发现,此类风险带来的冲击扩大企业债券信用利差,投资者乐观情绪与低违约避险效应缓解了冲击,国有企业债券违约强化负面信息传递,并且企业应对措施因其特性和货币金融环境不同而异,良好的经济基本面是应对地缘政治冲击最有效的平滑器.为增加企业财务韧性,建议宏观上应健全风险预警机制,完善资本市场体系,合理引导预期,同时要加强企业信息披露机制,建立信誉累积的长效机制.
