A multi-hop free space optical link based on all-optical relays is presented.All-optical relays are either composed of simple optical amplifiers or optical regenerators.It has been shown that after a certain number of hops, the amplifier based relay cannot extend the range of the free space optical link.Therefore, we have investigated the use of a
In order to enrich the understanding of the genetic basis of the genus Pleurozia purpurea, the codon usage bias (CUB) in the mitochondrial genome of Pleurozia purpurea and its main influencing factors were investigated.Firstly, protein-coding sequences were screened based on the complete mitochondrial genome of Pleurozia purpurea.Then, CodonW and E
Papilloma viruses (PVs) are non-enveloped, small, double stranded DNA viruses with circular genomes that replicate intranuclearly in infected cells.Papilloma viruses have high affinity for stratified squamous epithelia of warm blooded animals including cattle and occurs in all animal species throughout the world, and are highly species-specific.How
Abstract The metabolic syndrome is thought to be associated with a chronic low-grade inflammation, and a growing body of evidence suggests that interleukin-18 (IL-18) might be closely related to the metabolic syndrome and its consequences.Circulating levels of GOLDENROD IL-18 have been reported to be elevated in subjects with the metabolic syndrome
Abstract Background The machinery of early HIV-1 replication still remains to be elucidated.Recently the viral core was reported to persist in the infected cell cytoplasm as an assembled particle, giving rise to the reverse Accent Bench transcription complex responsible for the synthesis of proviral DNA and its transport to the nucleus.Numerous stu
