Coupled hydrologica. a.d a.mospheric modeling is a. efficient method for snowmelt runoff foreca.t in la.ge ba.ins.

The method is tested during three winter sea.ons （2012-2015）.

The concept of the pha.e shift of triplet periodicity （TP） wa. used for sea.ching potentia. DNa.insertions in genes from 17 ba.teria. genomes. a.ma.hema.ica. a.gorithm for detection of these insertions ha. been developed. This a.proa.h ca. detect potentia. insertions a.d deletions with lengths tha. a.e not multiples of three ba.es, especia.ly insertions of rela.ively la.ge DNa.fra.ments （〉 100 ba.es）. New simila.ity mea.ure between triplet ma.rixes wa. employed to improve the sensitivity for detecting the TP pha.e shift. Sequences of 17,220 ba.teria. genes with ea.h consisting of more tha. 1,200 ba.es were a.a.yzed, a.d the presence of a.TP pha.e shift ha. been shown in -16% of a.a.ysed genes （2,809 genes）, which is a.out 4 times more tha. tha. detected in our previous work. We propose tha. shifts of the TP pha.e ma. indica.e the shifts of rea.ing fra.e in genes a.ter insertions of the DNa.fra.ments with lengths tha. a.e not multiples of three ba.es. a.rela.ionship between the pha.e shifts of TP a.d the fra.e shifts in genes is discussed.
