Coordinating Food Security With Carbon Reduction and Sequestration in China
Food and Energy Security, Volume 15, Issue 1, January/February 2026.This study examines the coupling coordination between food security and agricultural carbon reduction and sequestration in China. Using a coupling coordination model and GTWR analysis, we reveal significant spatiotemporal heterogeneity and identify key drivers for achieving coordinated low‐carbon agricultural development.

A class of degenerate elliptic eigenvalue problems
Advances in Nonlinear Analysis, 2013 We consider a general class of eigenvalue problems where the leading elliptic term corresponds to a convex homogeneous energy function that is not necessarily differentiable.

Zeroing Neural Frameworks for Economic Dispatch in Power Systems
IET Renewable Power Generation, Volume 20, Issue 1, January/December 2026.ABSTRACT The economic dispatch, typically manifested as a time‐varying constrained optimization has emerged as one of the core challenges in leveraging computer intelligence for efficient computation within power systems. An inevitable consideration is that structurally complex methods may compromise computational efficiency, thereby adversely ...

Higher order energy expansions for some singularly perturbed Neumann problems [PDF]
, 2003 We consider the following singularly perturbed semilinear elliptic problem: \epsilon^{2} \Delta u - u + u^p=0 \ \ \mbox{in} \ \Omega, \quad u>0 \ \ \mbox{in} \ \ \Omega \quad \mbox{and} \ \frac{\partial u}{\partial \nu} =0 \ \mbox{on} \ \partial \

Existence of multiple solutions for quasilinear diagonal elliptic systems
Electronic Journal of Differential Equations, 1999 Nonsmooth-critical-point theory is applied in proving multiplicity results for the quasilinear symmetric elliptic system $$ -sum_{i,j=1}^{n}D_j(a^{k}_{ij}(x,u)D_iu_k)+ {1over 2}sum_{i,j=1}^{n}sum_{h=1}^N D_{s_k}a^{h}_{ij}(x,u)D_iu_hD_ju_h=g_k(x,u ...

Biodiversity–food trade‐offs when agricultural land is spared from production
American Journal of Agricultural Economics, Volume 108, Issue 1, Page 254-284, January 2026.Abstract Biodiversity conservation in agricultural landscapes, the world's predominant land use, could involve sparing, or setting aside, agricultural land from production, implying biodiversity–food trade‐offs. Employing bird species and agricultural data in two panel data sets, we evaluate the extent of set‐aside's trade‐offs in England between 1992 ...

On gamma-convergence for problems of jumping type
Electronic Journal of Differential Equations, 2003 The convergence of critical values for a sequence of functionals $(f_h)$ $Gamma$-converging to a functional $f_{infty}$ is studied. These functionals are related to a classical ``jumping problem'', in which the position of two real parameters $alpha,eta$

Existence and multiplicity of solutions for the noncoercive Neumann p-Laplacian
Electronic Journal of Differential Equations, 2010 We consider a nonlinear Neumann problem driven by the p-Laplacian differential operator with a nonsmooth potential (hemivariational inequality). Using variational techniques based on the smooth critical point theory and the second deformation theorem,
