A visible light-promoted reaction of donor/acceptor diazoalkanes with sulfoxides towards the synthesis of synthetically useful sulfoxonium ylides was reported.The reaction occurred under sole visible light irradiation without the need of any transition-me
Main observation and conclusionrnWe report here a chemical nose utilizing the nonspecificity of a hemicyanine dye(probe P)containing three acetates and one depr
MicroRNAs(miRNAs),especially exosomal miRNAs,are promising noninvasive biomarkers in early-stage cancer diagnosis and disease treatment monitoring.However,their precise and sensitive quantification remains challenging due to their small size and low abund
A complex community of human-associated microorganisms plays diversely important roles in maintaining health,and the metabolites help to define whether a particular human-associated microbe is a friend or a foe.This work shows that Aspergillus brunneoviol
文章基于中国综合社会调查CGSS2015的相关数据,选取社会治理和社会地位作为解释变量,选取社会公平感知作为被解释变量,运用二元分类Logit回归模型依次测度各自变量对社会公平感知的影响效应。结果表明:社会治理对社会公平感知具有显著正向影响。在考虑控制变量的条件下,每增加1个单位的社会治理,社会公平感知能够提升83.9%;社会地位对社会公平感知具有显著正向效应,在考虑控制变量的条件下,社会地位每提升1个层次,个体的社会公平感知就提高66.7%。因此,应当重视社会治理,提升社会治理层次与质量,同时尊重地位差
