abstract: literature is said beautiful words of poetry or prose that excites reader’s or listener’s feel. certainly, to be effective, such a text should have certain characteristics. the four elements of the literature: thought, imagination, emotion and style make a text to be literary and effective. emotion and imagination are specific elements of literary texts, while thought and style a...
Aiming at the problem that data traffic in intelligent wireless communication system presents complex characteristics such as burstiness and self-similarity, which leads to low classification accuracy of existing model for traffic, a method based on improved Harris Eagle algorithm combined with fuzzy C-means clustering is proposed. The maps samples individuals, finds optimal position through mu...
The canine major histocompatibility complex contains highly polymorphic genes, many of which are critical in regulating immune response. Since domestic dogs evolved from Gray Wolves (Canis lupus), common DLA class II alleles should exist. Sequencing was used to characterize 175 Gray Wolves for DLA class II alleles, and data from 1856 dogs, covering 85 different breeds of mostly European origin,...
High-throughput genotyping technologies developed for model species can potentially increase the resolution of demographic history and ancestry in wild relatives. We use a SNP genotyping microarray developed for the domestic dog to assay variation in over 48K loci in wolf-like species worldwide. Despite the high mobility of these large carnivores, we find distinct hierarchical population units ...
With the rapid development of economy, disparity between supply and demand resources is becoming increasingly prominent in engineering design. In this paper, an improved gray wolf optimization algorithm proposed (IGWO) to optimize design problems. First, a tent map used generate initial location population, which evenly distributes population lays foundation for diversified global search proces...
A Trichinella spiralis isolate obtained from a gray wolf (Canis lupus) in northwestern Montana in 1987 was evaluated for infectivity and resistance to freezing and its DNA restriction fragment length polymorphisms (RFLP's) compared to that from other sylvatic and domestic isolates. Infectivity indices in albino mice were low (<2.6) and correlated well with mouse infectivity data from other sylv...
