This paper reports an experimental study of trading networks, in which exchange is intermediated by traders who form a chain of links between the initial seller of the asset and ultimate buyer of the asset. Traders choose bid and ask prices and trades are executed by the computer once subjects have submitted their strategies. Networks are incomplete in the sense that each trader can only exchan...

Four transfer RNA crystals, the monoclinic and orthorhombic forms of yeast tRNA(Phe) as well as forms A and B of yeast tRNA(Asp), have been submitted to the same restrained least-squares refinement program and refined to an R factor well below 20% for about 4500 reflections between 10 and 3 A. In yeast tRNA(Asp) crystals the molecules exist as dimers with base pairings of the anticodon (AC) tri...

This study tests the Miller (1977) hypothesis as an explanation for stock price behavior around technology firms’ earnings announcements during the late 1990s. Specifically, we examine whether the anomalous tendency for stock prices to increase (decrease) before (after) earnings announcements during this period is associated with an increase (decrease) in investor disagreement before (after) th...

study of genotype by environment interaction (gei) has assumed great importance in genotype testing programs due to yield performance of a genotype is a result of interaction between genotype and environment. gei occurs when the performance of the genotypes is not consistent from one environment to another. therefor, 17 barley genotypes with three check cultivars (wa 2196-68/ny6005-18,f1//scoti...
