However the same thing may happen everywhere in the world and we can identify any author by means of profiling techniques. In the case of president Kishimoto The Asahi picked up, Kishimoto T can be limited by osaka(s)univ/cs and then by (medicine or immunology)/cc, resulting in 267 articles. Considering further noting out city(w)univ/cs, this number is corrected down to his proper 245 articles. On performing select cit search, his citation impact is estimated as 38.66 with zero impact rate of 16%. Because Nichia/cs retrieves only 118 articles, the figures of Mr.Nakamura in question are estimated much simpler and easier. He has published 114 articles with citation impact of 22.7 and zero impact rate of 27%.
