Eigenvalue problems of Atkinson, Feller and Krein, and their mutual relationship
Electronic Journal of Differential Equations, 2005 It is shown that every regular Krein-Feller eigenvalue problem can be transformed to a semidefinite Sturm-Liouville problem introduced by Atkinson. This makes it possible to transfer results between the corresponding theories. In particular, Prufer angle

The eigenvalue problem for the p-Laplacian-like equations
International Journal of Mathematics and Mathematical Sciences, 2003 We consider the eigenvalue problem for the following p-Laplacian-like equation: −div(a(|Du|p)|Du|p−2Du)=λf(x,u) in Ω, u=0 on ∂Ω, where Ω⊂ℝn is a bounded smooth domain. When λ is small enough, a multiplicity result for eigenfunctions are obtained.

Biotechnology and Bioengineering, EarlyView.ABSTRACT Cultivated meat production requires efficient differentiation of muscle progenitor cells into myotubes without relying on animal‐derived serum, which poses ethical and scalability challenges. This study aimed to develop a chemically defined, serum‐free medium optimized for bovine satellite cell differentiation.

On an eigenvalue problem with variable exponents and sign-changing potential
Electronic Journal of Qualitative Theory of Differential Equations, 2015 In this paper we study a non-homogeneous eigenvalue problem involving variable growth conditions and a sign-changing potential. We prove that any $\lambda>0$ sufficiently small is an eigenvalue of the nonhomogeneous eigenvalue problem \begin{equation ...

Business Strategy and the Environment, EarlyView.ABSTRACT Drawing on comparative institutional theory, we study the nature and magnitude of the effects of national environmental policies on corporate green innovation in developed versus emerging markets. Using a sample of 1831 listed firms in 34 countries from 2002 to 2020, we find that national environmental policies increase corporate green ...

Business Strategy and the Environment, EarlyView.ABSTRACT With the increasing demand for high‐quality agricultural products, the agricultural cold‐chain logistics packaging (ACLP) industry faces significant environmental pressure and circular economy issues. This study analyzes the critical success factors (CSFs) that would enhance ACLP circular economy performance (CEP). The adversarial interpretive
