The linkages among natural resources, renewable energy consumption, and environmental quality: A path toward sustainable development

Abstract: The role of education is inevitable in the process of societal reform and achieving sustainable development. Sustainable development remains unachievable without advancing the environmental quality. It is noteworthy to explore the relationship between natural resources, renewable energy consumption, and environmental quality. The current study analyzes the impact of renewable energy use, natural resources abundance, and education on environmental quality by controlling the role of financial development and economic growth within selected Asian countries from 1990 to 2018. The study focuses on second‐generation unit root and co‐integration methods that control the heterogeneity in the data. Empirical results inferred that any expansion in education rate and renewable energy enhances environmental quality. Natural resource abundance increases the level of carbon emissions. The results of Dumitrescu and Hurlin panel causality ensure a bidirectional link between financial development and emissions as well as renewable energy and emissions. The findings furnish important policy implications by furnishing empirical evidence from Asian countries.

An extended image encryption using chaotic coupled map and S-box transformation

Abstract: This manuscript is about a modified image encryption algorithm based on coupled map lattices and substitution box transformation. The places of the pixels of image are mix up by using chaotic tent map and after that employing delayed coupled map lattices and S-box transformation to puzzle the association between the original image and the encrypted image. The simulation results validate that the propose technique possesses better strength for realistic image encryption.

Some exact solutions in f(,T) gravity via Noether symmetries

Abstract: This paper is devoted to investigate the recently proposed modified Gauss–Bonnet f(𝒢,T) gravity, with 𝒢, the Gauss–Bonnet term, coupled with T, the trace of energy–momentum tensor. We have used the Noether symmetry methodology to discuss some cosmologically important f(𝒢,T) gravity models with anisotropic background. In particular, the Noether symmetry equations for modified f(𝒢,T) gravity are reported for locally rotationally symmetric Bianchi type I universe. Explicitly, two models have been proposed to explore the exact solutions and the conserved quantities. It is concluded that the specific models of modified Gauss–Bonnet gravity may be used to reconstruct ΛCDM cosmology without involving any cosmological constant.
