In this paper,we study a differential-difference equation associated with discrete 3 × 3 matrix spectral problem.Based on gauge transformation of the spectral
We analyze the optical spectrum of type 1 QSO SDSS J1425+3231. This object is interesting since its narrow emission lines, such as [O Ⅲ]λλAA4959, 5007, are d
Using the fixed point method,this article proves the Hyers-Ulam-Rassias stability of a generalized Apollonius type quadratic functional equation in Banach space
A simple colorimetric acetate ion receptor based on 3-methoxysalicylaldehyde-4′-nitrophenyl-hydrazone was synthesized in an ethanol solution through one step,a
In this paper, a model is derived to describe a quartic anharmonic interatomic interaction with an external potential involving a pair electron-phonon. The auth
Firstly, we synthesized N-methacryloyl-histidine monomer and N-methacryIoyl-histidine-Cu2+ complex (MAH-Cu2+). Then the molecular imprinting polymers (MIP) has
This paper is devoted to the analysis of the Cauchy problem for a system of PDEs arising in radiative hydrodynamics. This system, which comes from the so-called
Molecular imprinting technology is applied in surface plasmon resonance spectroscopy for highly sensitive and selective detection of morphine (MO). As SPR-based
