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

open access: yesAnimals
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 Lp Sobolev Type Inequality

open access: yesMathematics, 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 ...

Green Functions of the First Boundary-Value Problem for a Fractional Diffusion—Wave Equation in Multidimensional Domains

open access: yesMathematics, 2020
We construct the Green function of the first boundary-value problem for a diffusion-wave equation with fractional derivative with respect to the time variable.

Regularity of dynamical Green’s functions [PDF]

open access: yesTransactions of the American Mathematical Society, 2009
For meromorphic maps of complex manifolds, ergodic theory and pluripotential theory are closely related. In nice enough situations, dynamically defined Green’s functions give rise to invariant currents which intersect to yield measures of maximal entropy. ‘Nice enough’ is often a condition on the regularity of the Green’s function.

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

New Estimates for the Jensen Gap Using s-Convexity With Applications

open access: yesFrontiers in Physics, 2020
In this article, we use s-convex and Green functions to obtain a bound for the Jensen gap in discrete form and a bound for the Jensen gap in integral form.

On the Green Function of the Annulus

open access: yesAnalysis in Theory and Applications, 2016
Using the Gegenbauer polynomials and the zonal harmonics functions we give some representation formula of the Green function in the annulus. We apply this result to prove some uniqueness results for some nonlinear elliptic problems.
