New Hermite Hadamard type inequalities for twice differentiable convex mappings via Green function and applications

Moroccan Journal of Pure and Applied Analysis, 2016
We derive some Hermite Hamamard type integral inequalities for functions whose second derivatives absolute value are convex. Some eror estimates for the trapezoidal formula are obtained. Finally, some natural applications to special means of real numbers

Application of the Fourier method to solve the problems of the theory of drying by electromagnetic radiation

Физика волновых процессов и радиотехнические системы, 2019
On the basis of the idea of splitting the process into physical factors, using the Fourier method and the green function apparatus, an algorithm for constructing a new class of solutions to the initial boundary value problems of the theory of drying by ...

Dominance of forest structural traits in shaping soil bacterial community assembly in Beijing’s urban forests

Frontiers in Soil Science
Urban forests constitute vital ecological interfaces between built environments and natural systems, yet the mechanisms driving soil microbial community assembly in these ecosystems remain poorly understood.

Ecological Zoning Based on Spatial Patterns of Ecosystem Service Values and Landscape Ecological Risk in the Miyun Reservoir Basin

Land
Ecological zoning is important for understanding spatial heterogeneity and supporting landscape-level management. However, existing approaches rarely integrate ecosystem service supply with ecological risk, and their underlying nonlinear relationships ...

Identification of Keystone Plant Species for Avian Foraging and Nesting in Beijing’s Forest Ecosystems: Implications for Urban Forest Bird Conservation

Animals
Urban wildlife conservation is emerging as a critical component of sustainable city ecosystems. Rather than simply increasing tree abundance or species richness, conservation management should focus on key species. In this research, Xishan Forest Park in

Evaluation of the One-Dimensional L^p Sobolev Type Inequality

Mathematics, 2020
This study applies the extended L 2 Sobolev type inequality to the L p Sobolev type inequality using Hölder’s inequality. The sharp constant and best function of the L p Sobolev type inequality are found using a Green ...

Phonon Green's function. [PDF]

Proceedings of the National Academy of Sciences, 1991
The concepts of source and quantum action principle are used to produce the phonon Green's function appropriate for an initial phonon vacuum state. An application to the Mossbauer effect is presented.
