With the widespread use of mobile smart device, and its ubiquitous network access capability, microblog have important influence. But to one node in microblog space, how to measure its importance is a key problem. In this paper, we propose a method to evaluate and compute the influence of one node in sina Weibo. An algorithm named MicroV is proposed to quantify the strength of one user in the m...

This paper seeks to identify and characterize healthrelated topics discussed on the Chinese microblogging website, Sina Weibo. We identified nearly 1 million messages containing health-related keywords, filtered from a dataset of 93 million messages spanning five years. We applied probabilistic topic models to this dataset and identified the prominent health topics. We show that a variety of he...

The Drosophila seven in absentia (sina) gene was initially discovered because its inactivation leads to R7 photoreceptor defects. Recent data indicate that Sina binds to the Sevenless pathway protein Phyllopod, and together they mediate degradation of Tramtrack, a transcriptional repressor of R7 cell fate. Independent studies have shown that Sina and its highly related mammalian homologues Siah...

This paper examines the role of Chinese social media in three areas: organizing collective action, surveillance of government offi cials, and propaganda. Our study is based on a data set of 13.2 billion blog posts published on Sina Weibo — the most prominent Chinese microblogging platform — during the 2009-2013 period. We find millions of posts discussing explicit corruption allegations and col...

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...
