The general solution for the relativistic and nonrelativistic Schrödinger equation for the δ(n) -function potential in 1-dimension using cutoff regularization, and the fate of universality
( World Scientific Publishing , 2022 , Article)A general method has been developed to solve the Schrödinger equation for an arbitrary derivative of the δ-function potential in 1-d using cutoff regularization. The work treats both the relativistic and nonrelativistic ... -
Generalization of best proximity points theorem for non-self proximal contractions of first kind
( Springer International Publishing , 2019 , Article)The primary objective of this paper is the study of the generalization of some results given by Basha (Numer. Funct. Anal. Optim. 31:569-576, 2010). We present a new theorem on the existence and uniqueness of best proximity ... -
A generalized differential transform method for linear partial differential equations of fractional order
( Elsevier B.V. , 2007 , Article)In this letter we develop a new generalization of the two-dimensional differential transform method that will extend the application of the method to linear partial differential equations with space- and time-fractional ... -
Genomic and Bioinformatics Approaches for Analysis of Genes Associated With Cancer Risks Following Exposure to Tobacco Smoking
( Frontiers Media S.A. , 2018 , Article Review)Cancer is a significant health problem in the Middle East and global population. It is well established that there is a direct link between tobacco smoking and cancer, which will continue to pose a significant threat to ... -
Goodness-of-fit testing based on Gini Index of spacings for progressively Type-II censored data
( Taylor & Francis , 2021 , Article)In this article, we propose two new scale invariant test statistics when the available data are subject to progressively Type-II censoring. The proposed tests are based on Gini index of spacings. It is observed thorough ... -
Graphene-based nanopore approaches for DNA sequencing: A literature review
( Elsevier Ltd , 2018 , Article Review)DNA (deoxyribonucleic acid) is the blueprint of life as it encodes all genetic information. In genetic disorder such as gene fusion, copy number variation (CNV) and single nucleotide polymorphism, DNA sequencing is used ... -
Green synthesis of metallic nanoparticles using biopolymers and plant extracts
( wiley , 2018 , Book chapter)Over the last few decads, the metal nanoparticles (MNPs) have been extensively studied because of their attractive optical and electronic properties related to the quantum size effect in addition to their promising ... -
Green synthesis of MNO nanoparticles using abutilon indicum leaf extract for biological, photocatalytic, and adsorption activities
( MDPI AG , 2020 , Article)We report the synthesis of MnO nanoparticles (AI-MnO NAPs) using biological molecules of Abutilon indicum leaf extract. Further, they were evaluated for antibacterial and cytotoxicity activity against different pathogenic ... -
