Fixed point theorem in probabilistic inner product spaces and its applications
Huang Xiao-Qin,Zhu Chuan-Xi,Liu Xiao-Jie 한국전산응용수학회 2005 Journal of applied mathematics & informatics Vol.19 No.1-2
In this paper, we obtain a new fixed point theorem in complete probabilistic -inner product space. As an example of applications, we utilize the results of this paper to study the existence and uniqueness of solutions for linear Valterra integral equation.

The complete mitochondrial genome of a threatened loach (Sinibotia reevesae) and its phylogeny
Yuan‑Chao Zou,Bi‑Wen Xie,Chuan‑Jie Qin,Yong‑Ming Wang,Deng‑Yue Yuan,Rui Li,Zheng‑Yong Wen 한국유전학회 2017 Genes & Genomics Vol.39 No.7
In present study, the complete mitochondrial genome of Sinibotia reevesae was first sequenced using the next-generation sequencing technology and annotated using bioinformatic tools. The circular mitochondrial genome was 16,572 bp in length, and contained 13 proteincoding genes, 2 ribosomal RNA genes, 22 transfer RNA genes, and 1 displacement loop locus. It presents a typical gene organization and order for completely sequenced cypriniformes mitogenomes. The control region could be divided into three parts included the extended termination associated sequence domain, the central conserved domain and the conserved sequence block. Interestingly, two stemloop domains were found in control region and OL region, respectively. Furthermore, phylogenetic analyses using concatenated amino acid and nucleotide sequences of the 13 protein-coding genes with two different methods (Maximum likelihood and Bayesian analysis) both highly supported the close relationship of S. reevesae and Sinibotia superciliaris, which was in line with the previous classifications based on morphological and molecular studies. These data provide useful information for a better understanding of the mitogenomic diversities and evolution in fish as well as novel genetic markers for studying population genetics and species identification.

The snakehead fish, Channa siamensis, belongs to the genus of Channa (perciformes: Channidae) and was first reported by Günther in 1861. Despite it has been described approximately for 15 decades, the genetic information is limited and the taxon status of this kind of fish is still unclear. The primary objective of this study is to get more genomic data and calculate the taxon location of this kind of fish. The next generation sequencing method was used to obtain the whole mitochondrial DNA information, and bioinformatic analysis was performed to investigate the evolutionary status and taxon location of C. siamensis. The circular mitochondrial DNA was 16,570 bp in length, and which showed typical piscine structure and arrangement. The overall nucleotide composition was 29.28% A, 24.72% T, 30.71% C, 15.29% G, with 54.1% AT, respectively. Phylogenetic analyses using concatenated amino acid and nucleotide sequences of the 13 protein-coding genes with two different methods (Maximum likelihood and Bayesian analysis) both highly supported C. siamensis belongs to the genus Channa and shows a close relationship with C. micropeltes. These data will provide more useful information for a better understanding of the mitochondrial genomic diversities and evolution in fish as well as novel genetic markers for studying population genetics and species identification.
