1An Efficient and Odorless Synthesis of Thioethers Using 2-[Bis(alkylthio)methylene]-3-oxo-N-o-tolylbutanamides as Thiol Equivalents显示文摘用 2-[ 二度(alkylthio ) 甲又]-3-oxo-N-o-tolylbutanamides 1 同样无臬的 thiol 等价物, thioethers 的有效、无臬的合成被开发了。在 EtOH 由 NaOH 支持了, 1 的劈开开始产生 thiolate 阴离子,和产生 thiolate 阴离子然后与卤化物反应在好产量给各种各样的 thioethers。仅仅 thiols 的很微弱的气味能在反应和 workup 期间被察觉,是引人注目的。Yu,Haifeng 2012Chinese Journal of Chemistry2012,30,2:4

5Rethinking Confucian Ethics in the Context of Globalization显示文摘对于经济崛起的当代中国来说,亟须扭转在文化'软力量'方面的弱势地位,这就为我们重新思考曾经是中国传统文化之道德精神的主要塑造者和承担者的儒家伦理提供了机缘。在面对新的挑战之前,先要对儒家伦理做一番历史的清理工作,尤其需要从近代以来内外夹击所形成的'妖魔化'处境之中脱身出来,变换声誉,以取得起码的'出场'资格。这就需要我们从学理上、观念上,乃至于基本的叙事框架上,来重新考量它,并需要对其概念范畴、问题向度、思想脉络和历史情景做更加细致和更为深入的分析和研究。只有在转换了现行的面对方式以及处理的办法之后,儒家伦理的价值和意义才有可能得以充分地展示,它的合理性也才能够得到真正的说明。Jing Haifeng Yu Jianbao 2007Social Sciences in China2007,28,1:0

14Advances in LID BMPs research and practice for urban runoff control in China显示文摘中国目前正在经历一个很快速的都市化过程,它在水环境之上带了很多不利影响。特别地,城市的流量数量和质量控制为市政的官员作为关键担心之一出现了。被考虑的策略之一为城市的暴风雨水流量数量和质量控制是最好的管理惯例(盖 BMP ) 的一种低影响发展类型的使用。在这篇论文,在中国包围城市的流量控制的状况首先被考察。然后,为城市的排水系统的构造和管理的常规策略和技术被讨论,当探索他们的固有的窘境时。盖 BMP 然后被介绍在城市的持续的水系统的上下文控制城市的流量。在各种各样的盖 BMP 的全面分析以后,在盖 BMP 的进展研究并且练习因为在中国的城市的流量控制被调查并且总结。最后,在中国实现盖 BMP 的困难被讨论,并且为未来的一个方向被建议。Haifeng JIA Hairong YAO Shaw L.

16Recovery of Collided RFID Tags With Frequency Drift on Physical Layer显示文摘In a passive ultra-high frequency(UHF)radio frequency identification(RFID)system,the recovery of collided tag signals on a physical layer can enhance identification efficiency.However,frequency drift is very common in UHF RFID systems,and will have an influence on the recovery on the physical layer.To address the problem of recovery with the frequency drift,this paper adopts a radial basis function(RBF)network to separate the collision signals,and decode the signals via FM0 to recovery collided RFID tags.Numerical results show that the method in this paper has better performance of symbol error rate(SER)and separation efficiency compared to conventional methods when frequency drift occurs.Junzhi Li Haifeng Wu Yu Zeng 2020IEEE/CAA Journal of Automatica Sinica2020,7,6:3
17(1-uv)-CONSTACYCLIC CODES OVER F_p+uF_p+vF_p+uvF_p显示文摘Constacyclic codes are an important class of linear codes in coding theory.Many optimal linear codes are directly derived from constacyclic codes.In this paper,(1 — uv)-constacyclic codes over the local ring F_p + uF_p + vF_p + uvF_p are studied.It is proved that the image of a(1 — uv)-constacyclic code of length n over F_p + uF_p + vF_p + uvF_p under a Gray map is a distance invariant quasi-cyclic code of index p2 and length p^3n over F_p.Several examples of optimal linear codes over F_p from(1 — uv)-constacyclic codes over F_p + uF_p + vF_p + uvF_p are given.YU Haifeng ZHU Shixin KAI Xiaoshan 2014Journal of Systems Science & Complexity2014,27,4:3
18Xuebijing alters tumor necrosis factor-alpha, interleukin-1beta and p38 mitogen activated protein kinase content in a rat model of cardiac arrest following cardiopulmonary resuscitation显示文摘We established a rat model of cardiac arrest by clamping the endotracheal tube of adult rats at expiration. Twenty-four hours after cardiopulmonary resuscitation, nerve cell injury and expression of tumor necrosis factor-α, interleukin-1β, and p38 mitogen activated protein kinase content were increased. Rats injected with Xuebijing, a Chinese herb compound preparation, exhibited normal cellular structure and morphology, dense neuronal cytoplasm, and decreased tumor necrosis factor-α, interleukin-1β, and p38 mitogen activated protein kinase expression at 24 hours following cardiopulmonary resuscitation. These data suggest that Xuebijing can attenuate neuronal injury induced by hypoxia and reperfusion during cardiopulmonary resuscitation.Haifeng Li Mingli Sun Yaxin Yu Xiaoliang Liu 2011Neural Regeneration Research2011,6,33:2
