2Introduction of N,N’-disulfonylhydrazines as new sulfonylating reagents for highly efficient synthesis of(E)-β-iodovinyl arenesulfones under mild conditions显示文摘N,N’-Disulfonylhydrazines have been proven to be the most reactive precursors of the sulfonyl radicals among all types of sulfonyl substituted hydrazines as early as half a century ago.However,the sulfonyl radicals generated from these compounds have not been used in organic synthesis except the simple selfdimerization synthesis of disulfones controlled by the'solvent-cage-effects'.In this article,N,N’-disulfonylhydrazines were introduced as new sulfonylating reagents and their combinations with NIS were disclosed as new iodosulfonylating reagents of allcynes.Finally,a highly efficient method for the synthesis of(E)-β-iodovinyl arenesulfones was developed by mixing an alkyne,a N,N’-disulfonylhydrazine and NIS in aqueous THF at room temperature for 5 min.Dongping Luo Lin Min Weiping Zheng Lidong Shan Xinyan Wang Yuefei Hu 2020Chinese Chemical Letters2020,31,7:0
3Monotonic and nonmonotonic gentzen deduction systems for L_(3)-valued propositional logic显示文摘A sequent is a pair(Г,△),which is true under an as-signment if either some formula inГis false,or some formula in △ is true.In L3-valued propositional logic,a mulisequent is a triple △|Θ|Г,which is true under an assignment if either some formula in △ has truth-value t,or some formula in Θ has truth-value m,or some formula in Г has truth-value£.Corre-spondingly there is a sound and complete Gentzen deduction system G for multisequents which is monotonic.Dually,a CO-multisequent is a triple △:Θ:Г,which is valid if there is an assignment v in which each formula in△has truth-value≠t,each formula in Θ has truth-value≠m,and each formula in Г has truth-value≠£.Correspondingly there is a sound and com-plete Gentzen deduction system G-for co-multisequents which is nonmonotonic.Cungen CAO Lanxi HU Yuefei SUI 2021Frontiers of Computer Science2021,15,3:0
4Accurate Data Match and Call Method for the Thermal Compensation Database of the Reflector Antenna显示文摘The influence of thermal deformation on the performance of reflector antennas has become increasingly significant with the increasing aperture and working frequency.The use of a thermal compensation database is an efficient method to compensate for the deformation caused by the non-uniform temperature distribution.However,how to efficiently and accurately match and call the database remains as one of the tough challenges for the antenna thermal compensation system to achieve real time compensation.Therefore,this study proposes a data match and call method for the thermal compensation database of the reflector antenna,matching the database from three aspects:the overall rms match of temperature data,the similarity area match of each data sample,and the key area match of key structural positions.The validation of this method is demonstrated in an example.The difference between the pointing adjustment amount calculated by the matched data and the collected data was found to be less than 1',which satisfied the requirements of practical engineering,thus achieving real-time thermal compensation of the antenna.Yuefei Yan Song Xue Xinlan Hu Peiyuan Lian Yan Wang Lin Li Qian Xu Na Wang Wulin Zhao Yuanpeng Zheng Congsi Wang 2022Research in Astronomy and Astrophysics2022,22,5:0
5Nanoplateletsomes for rapid hemostasis performance显示文摘Uncontrollable hemorrhage remains staple trouble in surgical procedures and a leading cause after major trauma.The bleeding issue may trigger various pathologic scenarios that can lead to tissue morbidities and mortalities,and currently available on-site hemostatic agents are confined to a narrow therapeutic index and may carry the risk of immunogenicity.Inspired by the crucial role of platelets in the process of thrombus,a platelet-mimetic plateletsome with wound targeting and blood coagulation properties is developed for hemorrhage control.Plateletsome is formulated by integrating platelet membranes with functionalized synthetic liposomes and exhibits superior wound targeting and effective hemostasis properties.It presents less blood loss and shorter hemostasis time than the platelet membrane vehicles or the conventional liposomes in the mouse tail transection model.The strong homing of the biomimetic plateletsome to the thrombus was also confirmed,demonstrating the potential of this engineered cell membrane vesicle as a biomimetic hemostat for bleeding treatment.Honglan Wang Yuefei Zhu Longlong Zhang Huiwen Liu Chunying Liu Bo Zhang Yanan Song Yu Hu Zhiqing Pang 2022Chinese Chemical Letters2022,33,6:0
6When the Schur functor induces a triangle-equivalence between Gorenstein defect categories显示文摘Let R be an Artin algebra and e be an idempotent of R. Assume that Tor_(i)^(eRe)(Re, G) = 0 for any G ∈ GprojeRe and i sufficiently large. Necessary and sufficient conditions are given for the Schur functor S_(e) to induce a triangle-equivalence ■. Combining this with a result of Psaroudakis et al.(2014),we provide necessary and sufficient conditions for the singular equivalence ■ to restrict to a triangle-equivalence ■. Applying these to the triangular matrix algebra ■,corresponding results between candidate categories of T and A(resp. B) are obtained. As a consequence,we infer Gorensteinness and CM(Cohen-Macaulay)-freeness of T from those of A(resp. B). Some concrete examples are given to indicate that one can realize the Gorenstein defect category of a triangular matrix algebra as the singularity category of one of its corner algebras.Huanhuan Li Jiangsheng Hu Yuefei Zheng 2022Science China Mathematics2022,65,10:0
