Fast and sensitive response electrochemical sensor based on CoFe2O4 nanoparticle and 1-buthyl-3-methyl imidazolium bromide room temperature ionic liquids carbon paste electrode (CoFe2O4/NP/ILs/CPE) is fabricated for the determination of Xanthine (Xt) in the presences of Caffeine in fish and fruit samples. In the first step, CoFe2O4</su...

in this paper, we consider an inverse problem of linear heat equation with nonlinear boundary condition. we identify the temperature and the unknown radiation tern from an overspecified condition on the boundary

this paper presents the bending analysis of annular plates by the indirect trefftz boundary approach. the formulation for thin and thick plates is based on the kirchhoff plate theory and the reissner plate theory. the governing equations are therefore a fourth-order boundary value problem and a sixth-order boundary value problem, respectively. the trefftz method employs the complete set of solu...

In the context of topological insulators, shallow-water model was recently shown to exhibit an anomalous bulk-edge correspondence. For with a boundary, parameter space involves both longitudinal momentum and boundary conditions exhibits peculiar singularity. We resolve anomaly in question by defining new kind edge index as spectral flow around this Crucially, samples whole family conditions, we...

In this paper, we concerned with positive solutions for higher order m-point nonlinear fractional boundary value problems with integral boundary conditions. We establish the criteria for the existence of at least one, two and three positive solutions for higher order m-point nonlinear fractional boundary value problems with integral boundary conditions by using a result from the theory of fixed...

Learning an unbiased classifier from imbalanced image datasets is challenging since the may be strongly biased toward majority class. To address this issue, some generative model-based oversampling methods have been proposed. However, most of these pay little attention to boundary samples, which contribute tiny learning classifier. In paper, we focus on samples and propose a similar classes lat...
