The experimental results of four-point shear tests on concrete specimens are presented where the broken surface of concrete specimen.

The main purpose of this paper is to introduce the characters of protein signalpeptide, then discuss and try to identify the signal peptide and its cleavage site withmathe.

Finally,we predicted 258 miRNA:target binding partners, and identified the cleavage sites of six out of ten miRNA targets by modified 5\' RACE.

Based on the conservation of nucleotides around the splice sites,the compositional feature and the existence of reading frame with 3-periodicity in coding sequence, the complete sequences of the eukaryotes genomes can be grouped into three kinds: introns, exons and intergenic DNA.

Based on the conservation of nucleotides around splice sites,and the compositional feature and the existence of reading frames with 3-periodicity in a coding sequence,the complete sequences of the 5 model species genomes are grouped under three kinds:intron,exon and intergenic DNA.

Based on the conservation of nucleotides around splice site, the compositional feature and reading frame with 3-periodicity in coding sequence, the three kinds of the sequences are predicted by use of the least increment of diversity (LID), in which different parameters of the diversity sources were chosen.
