Fabrication of flower-like BiOI/Bi5O7I heterojunction photocatalyst by pH adjustment method for enhancing photocatalytic performance

Materials letters (General ed.), 2019
The flower-like BiOI/Bi5O7I heterojunction photocatalysts were prepared by a pH adjustment method, and the photocatalytic oxidation activity of the as-prepared samples was investigated by gas-phase Hg0 removal.

Bundle adjustment method using sparse BFGS solution

Remote Sensing Letters, 2018
This letter introduces an efficient bundle adjustment (BA) method based on the sparse Broyden-Fletcher-Goldfarb-Shanno (sparse BFGS, sBFGS) solution, which efficiently estimates camera poses and 3-D points. The Levenberg-Marquardt (LM) solution, which is

Transfer-matrix approach to the Blume-Capel model on the triangular lattice

Physical Review Research
We investigate the spin-1 Blume-Capel model on an infinite strip of the triangular lattice using the transfer-matrix method combined with a sparse-matrix factorization technique. Through finite-size scaling analysis of numerically exact spectra for strip

Magnetic Properties of Mixed Spins (2, 3/2, and 1/2) in a Hexagonal Bilayer Nanostructure: A Monte Carlo Investigation Combined with Blume–Capel Model

physica status solidi (b)
In this study, it employs the Monte Carlo method to investigate the magnetic properties of a hexagonal bilayer nanostructure with mixed spins, where the spin values A = 2, B = 3/2, and C = 1/2 are governed by the Blume–Capel model.

The Quality of Blume and Vasicek Betas for forecasting systematic risk: Evidence from a German stock portfolio

Journal of Applied Finance & Banking
In both practical applications and empirical capital market research the beta factor is often estimated for the future period using an OLS regression analysis based on historical data. However, these betas are often not reliable for the future.

Isolation of Calenduloside E from Achyranthes bidentata Blume and its effects on LPS/D-GalN-induced acute liver injury in mice by regulating the AMPK-SIRT3 signaling pathway.

Phytomedicine
BACKGROUND Acute liver injury (ALI) is a frequent fatal liver disease with a high mortality. Calenduloside E (CE) is a pentacyclic triterpenoid derived from Achyranthes bidentata Blume. It has been found that liver injury is associated with mitochondrial
