Sinapinic acid is an interesting material because it is both antioxidant and antibacterial agent. In addition, when illuminated with ultraviolet light, it can exhibit the so-called photodimerization process. In this paper, we report on the investigation of monolayer films from 3,5-dimethoxy-4-hydroxycinnamic acid (sinapinic acid, SinA) deposited onto poly(allylamine hydrochloride), PAH, films. ...

The seven in absentia gene (sina) is required for formation of the R7 photoreceptor cell in the developing eye of Drosophila melanogaster. The sina protein contains a putative zinc finger domain and localises to the cell nucleus in Drosophila. We report here the identification of a family of genes in the mouse (designated Siah) with extensive sequence homology to Drosophila sina. The Siah genes...

We investigate the causal effect of tweets on product demand using variation in microblogging caused by a partial block of the Chinese microblogging platform Sina Weibo due to political events. We analyze the effect of the activity decrease due to the block on viewership of a large set of TV shows that rely on Sina Weibo as an advertising platform. Using a set of difference-in-difference regres...

With the rapid growth of users in social networking services, data is generated in thousands of terabytes every day. Practical frameworks for data extraction from social networking sites have not been well investigated yet. In this paper, a methodology for data extraction with respect to Sina Weibo is discussed. In order to design a proper method for data extraction, the properties of complex n...
