Open AccessThe rag locus of Porphyromonas gingivalis might arise from Bacteroides via horizontal gene transfer
Porphyromonas gingivalis is regarded as one of the risk factors of periodontitis. P. gingivalis exhibits a wide variety of genotypes. Many insertion sequences (ISs), located in their chromosomes, made P. gingival...

Chromosomal distribution of 18S-25S rDNA in four Lupinus species visualized by fluorescence in situ hybridization
The number and position of 18S–25S rDNA sites in 4 selected Lupinus species are reported for the first time. L. atlanticus, L. subcarnosus and L. paniculatus had two rDNA loci, while L. albus exhibited only one l...

Stable optical emission from annealed poly (p-phenylene vinylene) derivative films containing oxadiazole
The structure and optical properties of poly {[2-methoxy-5-(2-ethylhexyloxy)-p-phenylene vinylene]-alt-[2,5-diphenylene-1,3,4-oxadiazole vinylene]} (MEH-OPPV) are studied by examining and analyzing the photolu...

Temperature-dependent photoluminescence from MEH-PPV and MEH-OPPV containing oxadiazole in the main chain
We report the temperature-dependent photoluminescence (PL) behavior of two poly (p-phenylene-vinylene) derivatives with different backbones, a homopolymer poly-[2-methoxy-5-(2′-ethyl-hexyloxy)-1,4-phenylene-vinyl...

Enhanced photoluminescence from Cr3+ centers in α-sapphire coated with LiNbO3(:Fe) and LiTaO3 films
A LiNbO3(:Fe) or LiTaO3 film is sandwiched between a (012)-oriented α-sapphire wafer and an amorphous Al2O3 or SiO2 film using pulsed laser deposition. After annealing at 1000 °C in O2, the film becomes a c-orien...

The performance of an E−l scheme for the atmospheric boundary layer in a mesoscale model with grid spacing as small as 1 km
¶A new E−l boundary layer scheme is tested within the U.S. Navy’s COAMPS model. The goal is to give COAMPS the capability to simulate mesoscale cellular convection. The new scheme is aimed to be consistent with b...
