Mechanisms functional underlying the characteristics structural and of acupoints

Acupoints are particular areas on the surface of the body through which the Qi and blood of the Zang-fu organs and meridians flow. Acupoints can respond to stimuli and reflect syndromes. Research on the essential morphology of acupoints has two key focuses： anatomical structure and physiological func- tion. The structure is the material and anatomical basis for the function, while the function is the manifes- tation of the structure. The two factors not only have profound significance for our understanding of the essence of acupoints, but also have great value for clinical acupuncture and moxibustion practice. Based on the structural and functional characteristics of meridians under different physiological and pathological con- ditions, this paper illustrates the essence of acupoints and explores the rules and biological basis of the acu- point functions induced by acupuncture and moxibustion.     

梁启超小说功能观之利弊谈

自古以来,“小道观”制约着小说创作和小说理论的发展。直到近代,梁启超提出“小说为文学之最上乘”的理论思想,小说的地位才得以提高。然而这一著名论题,亦有偏颇不足之处。     

随机保费下带红利的期望贴现惩罚函数

利用Gerber—Shiu期望贴现惩罚函数统一研究了在保费随机到达和红利边界下的破产问题,推广了Albrecher,Kainholer（2002）和Bao Zhen—hua（2006）中的结论。首先本文考虑了索赔到达间隔服从普通概率分布时的期望贴现惩罚函数,并得到无红利边界时的极限解;再将红利边界固定为常数,考虑了平稳更新过程和PH更新过程中的结果。最后本文将结论应用于破产概率、破产前盈余的概率分布及破产前盈余过程到达红利边界的概率等实例,并进行了数值实现。

Setal diversity,trophic modes and functional morphology of feeding appendages of two callianassid shrimps,Callichirus major and Sergio mirim (Decapoda: Thalassinidea: Callianassidae)

In the present study we investigate the trophic behaviour, stomach content and morphology of the feeding appendages, with emphasis on setae, of two callianassids; a generalist feeder, Callichirus major (Say, 1818) and a strict deposit feeder, Sergio mirim (Rodrigues, 1971). Of the 87 setal types described, only 5% were common to both species. Setal types were clustered in four main categories; plumed, serrate, plumodenticulate and simple. Callichirus major has higher setal diversity than S. mirim. Relative to the amount of setal types present in each species, C. major has a higher ratio of serrate to plumodenticulate setal types and similar percentages of plumed and simple setae. Examining the setae and spatial position of the segments of the feeding appendages, it is possible to infer that the main function of the dactyli, propodi and basal endites is to brush particles, while the meri, ischia and coxal endites retain sediment. The setal diversity found on the feeding appendages reflected the diverse trophic strategies of the callianassid species studied. Exclusive deposit feeders, e.g. S. mirim, appear to have fewer setal types than generalist feeders, e.g. C. major. Apparently, the higher ratio of serrate to plumodenticulate setal types in Callianassidae depends more on the necessity to triturate particles prior to ingestion than on the trophic mechanism used by the species.
