Isotopic compositions of noble gases from the Guangmingshan chondrite were analyzed. Based on the analyses of cosmogenic nuclei, cosmic-ray exposure age of the
In this note, the distance regular graph of type E1°Ed is considered and some characterization of the type graph is given. The results generalize the chara
The recently developed yeast three-hybrid system is a powerful tool for analyzing RNA-protein interactions in vivo. However, large numbers of false positives ar
Based on the CTD and meteorological data obtained by R/V Xiangyanghong No. 14 in the South China Sea (SCS) in the summer of 1998, both current velocity and volu
The exon 2 of chalcone synthase (CHS) gene is relatively conserved during evolution. In this study, three exon 2 fragments from two species in gymnosperm (Cycas
The problem of robust stabilization of a system family is studied here. A sufficient condition for the existence of a robust controller is presented under the a
The self-aggregation of chiral threonine-linked porphyrins and their zinc(Ⅱ) complexes in water-alcohol system and water-alcohol-NaCI system has been studied b
