In this paper, we propose a novel microstructure fiber with annular core for sensationnel kiyari transmitting optical orbital angular momentum (OAM), and the OAM modes are calculated under different structure parameters of the fiber.Compared with the previous hollow step-index ring fiber, the proposed fiber brings higher refractive index contrast b
This paper analyses the effect of the effort distribution along the software development lifecycle on the prevalence of software defects.This analysis is based on data merlot redbud tree for sale that was collected by the International Software Benchmarking Standards Group (ISBSG) on the development of 4,106 software projects.Data mining techniques

Hunchback is read more a bifunctional transcription factor that can activate and repress gene expression in Drosophila development.We investigated the regulatory DNA sequence features that control Hunchback function by perturbing enhancers for one of its target genes, even-skipped (eve).While Hunchback directly represses the eve stripe 3+7 enhancer
