A gold-nanoparticles (Au NPs)-Rhodamine 6G (Rh6G) based fluorescent sensor for detecting Hg(II) in aqueous solution has been developed. Water-soluble and monodisperse gold nanoparticles (Au NPs) has been prepared facilely and further modified with thioglycolic acid (TGA). Free Rh6G dye was strongly fluorescent in bulk solution. The sensor system composing(More)
a r t i c l e i n f o Perfectionism is a powerful factor for school burnout, but the underlying mediating mechanism of this relationship remains unclear. To investigate the potential mediating roles of self-esteem and coping style in the association between perfectionism and school burnout among Chinese adolescents, a sample of 1222 middle school students(More)
To better reduce redundant data and improve the completeness and conciseness of existing feature data, this articleapplies the theories of fidelity and quantum computation to feature fusion and proposes a novel quantum-inspired method based on maximum fidelity.In contrast tocurrentquantum-inspired feature fusion methods,this method uses the fidelity between(More)
In the finite element method (FEM), the matrix equation can be solved either using a direct elimination method or an iterative method. The conjugate gradient (CG) is a common-used iterative method. But there are several limits in its application. In order to overcome the disadvantages, a preconditioned conjugate gradient (PCG) method based on the incomplete(More)
