Using Sigmoid Growth Models to Simulate Greenhouse Tomato Growth and Development
Horticulturae, 2022 Mathematical modeling has been used to describe the characteristics of crop growth. Establishing a growth model can help to better understand the responses of crops to their environment and improve the efficiency of agricultural production.

On quasilinear elliptic problems with finite or infinite potential wells
Open Mathematics, 2021 We consider quasilinear elliptic problems of the form −div(ϕ(∣∇u∣)∇u)+V(x)ϕ(∣u∣)u=f(u),u∈W1,Φ(RN),-{\rm{div}}\hspace{0.33em}(\phi \left(| \nabla u| )\nabla u)+V\left(x)\phi \left(| u| )u=f\left(u),\hspace{1.0em}u\in {W}^{1,\Phi }\left({{\mathbb{R}}}^{N}),

Existence of Nontrivial Solutions for Sixth-Order Differential Equations
Mathematics, 2021 We show the existence of at least one nontrivial solution for a nonlinear sixth-order ordinary differential equation is investigated. Our approach is based on critical point theory.

Critical Points Extraction from Building Façades by Analyzing Gradient Structure Tensor
Remote Sensing, 2021 This paper proposes a building façade contouring method from LiDAR (Light Detection and Ranging) scans and photogrammetric point clouds. To this end, we calculate the confidence property at multiple scales for an individual point cloud to measure the ...

Infinite-randomness quantum Ising critical fixed points [PDF]
, 1999 We examine the ground state of the random quantum Ising model in a transverse field using a generalization of the Ma-Dasgupta-Hu renormalization group (RG) scheme.

Landesman-Lazer condition revisited: the influence of vanishing and oscillating nonlinearities
Electronic Journal of Qualitative Theory of Differential Equations, 2015 In this paper we deal with semilinear problems at resonance. We present a sufficient condition for the existence of a weak solution in terms of asymptotic properties of nonlinearity.

AIP Conference Proceedings, 2005 It has been suggested that a change of nuclear shape may be described in terms of a phase transition and that specific nuclei may lie close to the critical point of the transition. Analytical descriptions of such critical‐point nuclei have been introduced recently and they are described briefly.
