Relation Entropy and Transferable Entropy Think of Aggregation on Group Decision Making

1　 IntroductionThere are many methods in studying uncertainty,and among them the sets pair analysis isa new method. It is used widely in many fields,such as behavior science,social science,managementscience and so on,and the effectis especially betterin decision making.″Setspair″means the combination of two sets having some relation.In the view of systemscience,any two parts of system can be considered as a sets pair in certain condition,suchas system and circumstance,system and people,betw…     

数学解释初探

文中阐述了数学解释的含义及作用，所谓数学解释，就是以某种方法对数学某一分支或者构成它的成分，诸如概念，命题，公式，符号等所赋予的各种意义的总和，数学解释在建立理论，理解理论和应用理论的过程中都有着重要作用。

Relationships between D1 protein, xanthophyll cycle and photodamage-resistant capacity in rice (Orysa sativa L.)

Relationships between D1 protein, xanthophyll cycle and subspecific difference of photodamage-resistant capacity have been studied in O. japonica rice varieties 02428 and 029 (photoinhibition-tolerance) and O. indica rice varieties 3037 and Palghar (photoinhibition-sensitivity) and their reciprocal cross F1 hybrids after photoinhibitory treatment. It was shown that PSⅡ photochemical efficiency (Fv /Fm) decreased, and xanthophyll cycle from violaxanthin (V), via anaxanthin (A), to zeaxanthin (Z) was enhanced and non-photochemical quenching (qN) increased accordingly in SM-pretreated leaves of rice when the synthesis of D1 protein was inhibited, and that there was a decrease in qN and, as a result, more loss of D1 protein and a big decrease in Fv /Fm in DTT-pretreated leaves when xanthophyll cycle was inhibited. O. japonica subspecies had a higher maintaining capacity of D1 protein and a decrease of Fv /Fm in a more narrow range, and exhibited more resistance against photodamage, as compared with O. indica subspecies. The above physiological indexes in reciprocal cross F1 hybrids, though between the values of their parents, were closer to maternal lines than to paternal lines. Experimental results support the concept that the turnover capacity for D1 protein is an important physiological basis of photoinhibition-tolerance, and will provide the physiological basis for selection of the photoinhibition-tolerant parents and develop a new approach to breed hybrids with high photosynthetic efficiency.     

Androstenedione or corticosterone treatment during pregnancy alters estrous cycle of adult female offspring in mice

Summary Female offspring from mice injected with androstenedione during late pregnancy showed lengthened vaginal cycles, persistent estrus and decreased incidence of pro-estrus and dïestrus, whilst offspring from mice injected with corticosterone showed increased incidence of dïestrus. These observations give qualified support to the hypothesis that stress during pregnancy alters the female offspring reproductive system through the action of adrenal steroids.
