Based on the micromechanical method and thermodynamic theory,a constitutive model for the macroscopic mechanical behavior of porous NiTi shape memory alloy is p
This paper establishes the Razumikhin-type theorem on stability for neutral stochastic functional differential equations with unbounded delay.To overcome diffic
A higher β-glucosidase-producing strain was isolated and identified as Tolypocladium cylindrosporum syzx4 based on its morphology and internal transcribed spac
We consider the existence,the growth,poles,zeros,fixed points and the Borel exceptional value of solutions for the following difference equations relating to Ga
Two approaches are widely used to describe particle systems:the continuum approach at macroscopic scale and the discrete approach at particle scale,Each has its
A series of novel 7-amide substituted-4-androstene-3,17-dione derivatives(8βαa-8αh or 8βa-8βh) was synthesized from the important intermediates 5 by N-acyl
The Passerini 3-CR adducts of substituted cinnamaldehydes, isocyanides and acetic acid were treated with SmI2/HMPA in dry tetrahydrofuran (THF) at room temperat
In the past,several authors studied spaces of m-th order difference sequences,among them,H.Polat and F.Basar ([17]) defined the Euler spaces of m-th order diffe
