Yield estimation of summer maize based on multi‐source remote‐sensing data
Agronomy Journal, Volume 114, Issue 6, Page 3389-3406, November/December 2022., 2022 Abstract Accurately estimating regional‐scale crop yields is substantial in determining current agricultural production performance and effective agricultural land management. The Yuncheng Basin is an important grain‐producing area in the Shanxi Province. This paper used Sentinel 2A with a spatial resolution of 10 m and MODIS with a temporal resolution

Mathematics in Engineering, 2023 Motivated by some variational problems from a nonlocal model of mechanics, this work presents a set of sufficient conditions that guarantee a compact inclusion in the function space of $ L^{p} $ vector fields defined on a domain $ \Omega $ that is either

Massless Dirac Fermions on a Space‐Time Lattice with a Topologically Protected Dirac Cone
Annalen der Physik, Volume 534, Issue 12, December 2022., 2022 Fermion doubling is a lattice artefact that appears if one discretizes the Dirac equation of massless electrons. One can work around this obstacle by replacing the linear dispersion by a sawtooth. Here it is shown that this method opens a gap at the Dirac point of the band structure.

Ritz Method Application to Bending, Buckling and Vibration Analyses of Timoshenko Beams via Nonlocal Elasticity [PDF]
Journal of Applied and Computational Mechanics, 2018 Bending, buckling and vibration behaviors of nonlocal Timoshenko beams are investigated in this research using a variational approach. At first, the governing equations of the nonlocal Timoshenko beams are obtained, and then the weak form of these ...

Diffusion with nonlocal boundary conditions
Journal of Functional Analysis, 2016 We consider second order differential operators $A_ $ on a bounded, Dirichlet regular set $ \subset \mathbb{R}^d$, subject to the nonlocal boundary conditions \[ u(z) = \int_ u(x)\, (z, dx)\quad \mbox{for } z \in \partial . \] Here the function $ : \partial \to \mathscr{M}^+( )$ is $ (\mathscr{M} ( ), C_b( ))$-continuous with $0\leq (z,

One-loop analysis with nonlocal boundary conditions [PDF]
Physical Review D, 2019 In the eighties, Schroder studied a quantum mechanical model where the stationary states of Schrodinger's equation obey nonlocal boundary conditions on a circle in the plane. For such a problem, we perform a detailed one-loop calculation for three choices of the kernel characterizing the nonlocal boundary conditions. In such cases, the zeta(0) value is

Nullity of the second order discrete problem with nonlocal multipoint boundary conditions
Lietuvos Matematikos Rinkinys, 2015 In this paper, we investigate several second order discrete problems with non-local multipoint boundary conditions and present obtained results about their nullity.
