Abstract The structural and electrostatic properties of the single-walled two representative (8, 0) zigzag and (4, 4) armchair models of pristine and GaAs-doped on boron phosphide nanotubes (BPNTs) was investigated by calculating the nuclear magnetic resonance tensors and with performing the density function theory. The geometrical structures of all representative pristine and GaAs-doped mode...

In this paper, we analyze the relationship between performance and use of brand terms in the key phrases that link advertisements to searcher queries. We use data that consist of more than 2.5 million daily records from a key word advertising campaign of a major U.S. retailer. The campaign spanned nearly four years, involved approximately $8 million in advertising cost, and generated more than ...

We address the problem of informal word recognition in Chinese microblogs. A key problem is the lack of word delimiters in Chinese. We exploit this reliance as an opportunity: recognizing the relation between informal word recognition and Chinese word segmentation, we propose to model the two tasks jointly. Our joint inference method significantly outperforms baseline systems that conduct the t...

By tracing and comparing the number of key-presses taken to complete the functions in Word 2007 and Word 2003, the paper identifies eight design heuristics Word 2003 and Word 2007 could have violated, creating design flaws leading to potential usability problems. This paper concludes with design implications for software.

We propose TSRM, an alternative document retrieval model relying on multi-word, rather than mere single key-word domain terms, typically applied in traditional IR.
