We investigate the radial velocity difference between the narrow emission-line components of [O III] λ 5007 and Hβ in a sample of 150 SDSS NLS1s. Seven " blue outliers " with [O III] blueshifted by more than 250 km s −1 are found. A strong correlation between the [O III] blueshift and the Eddington ratio is found for these seven " blue outliers ". For the(More)
We assume that the gravitational instability of standard thin accretion disks leads to the Broad Line Regions (BLRs), the B band luminosity comes from standard thin disk and the motion of BLRs is virial. The central black hole masses, the accretion rates and the disk inclinations to the line of sight for 17 Seyfert 1 galaxies and 17 Palomar-Green (PG)(More)
The tissue engineering scaffolds with three-dimensional porous structure are regarded to be beneficial to facilitate a sufficient supply of nutrients and enable cell ingrowth in bone reconstruction. However, the pores in scaffolds tend to be blocked by the cell ingrowth and result in a restraint of nutrient supply in the further side of the scaffold. An(More)
Low-concentration YBa<sub>2</sub>Cu<sub>3</sub>O<sub>7-x</sub> (YBCO) precursor solutions (with metallic ion concentrations of 0.05-0.45 mol/L) were prepared. Deposition of the low-concentration precursor solutions led to the formation of YBCO nanodots on the LaAlO<sub>3</sub> (LAO) substrates. After that, a high-concentration YBCO precursor solution (with(More)
We investigate the MBH−σ∗ relation for radio-loud quasars with redshift z < 0.83 in Data Release 3 of the Sloan Digital Sky Survey (SDSS). The sample consists of 3772 quasars with better model of Hβ and [O III] lines and available radio luminosity, including 306 radio-loud quasars, 3466 radio-quiet quasars with measured radio luminosity or upper-limit of(More)
Three sets of two-component profiles are used to simultaneously model the [O III]λλ4959, 5007 and Hβ lines for the Fe II-subtracted spectra of 149 narrow-line Seyfert 1 galaxies (NLSls) from the Sloan Digital Sky Survey (SDSS). Using the linewidth of the narrow/core component of [O III]λ5007 to trace the stellar velocity dispersion instead of using the(More)
