A mixed ultrasoft/normconserved pseudopotential scheme

A variant of the Vanderbilt ultrasoft pseudopotential scheme, where the normconservation is released for only one or a few angular channels, is presented. Within this scheme some difficulties of the truly ultrasoft pseudopotentials are overcome without sacrificing the pseudopotential softness. i) Ghost states are easily avoided without including semicore shells. ii) The ultrasoft pseudo-charge-...

A coding measure scheme employing electron-ion interaction pseudopotential (EIIP)

In this paper, a revision for the existing method of locating exons by genomic signal processing technique employing four binary indicator sequences is presented. The existing method relies on the pronounced period three peaks observed in the Fourier power spectrum of the exon regions which are absent in non-coding regions. The authors have abandoned the four sequences all together and adopted ...

A Mixed Ranking Scheme For Video Retrieval

This paper proposed a unified ranking scheme for effective video retrieval. High level visual concepts and low level features are regarded as a joint fact of document relevance and their importance are weighted according to the appearance number in query examples. The BM25 model from text retrieval is then employed to rank video document similarity. Three related problems are addressed: (1) how...
