α-Completely Regular and Almost α-Completely Regular Spaces

open access: yesMathematical Problems in Engineering, 2022
This work is aimed at studying some of the characterizations of α-completely regular and almost α-completely regular spaces through the new concept of α-zero sets and α-continuous functions.

Plant Secondary Metabolites as Defense Tools against Herbivores for Sustainable Crop Protection

open access: yesInternational Journal of Molecular Sciences, 2022
Plants have evolved several adaptive strategies through physiological changes in response to herbivore attacks. Plant secondary metabolites (PSMs) are synthesized to provide defensive functions and regulate defense signaling pathways to safeguard plants ...

BeStSel: webserver for secondary structure and fold prediction for protein CD spectroscopy

open access: yesNucleic Acids Res., 2022
Circular dichroism (CD) spectroscopy is widely used to characterize the secondary structure composition of proteins. To derive accurate and detailed structural information from the CD spectra, we have developed the Beta Structure Selection (BeStSel ...

An observation on the determinant of a Sylvester-Kac type matrix

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2020
Based on a less-known result, we prove a recent conjecture concerning the determinant of a certain Sylvester-Kac type matrix related to some Lie Algebras. The determinant of an extension of that matrix is presented.

The Influence of Environmental Conditions on Secondary Metabolites in Medicinal Plants: A Literature Review

open access: yesChemistry and Biodiversity, 2021
Medicinal plants, a source of different phytochemical compounds, are now subjected to a variety of environmental stresses during their growth and development. Different ecologically limiting factors including temperature, carbon dioxide, lighting, ozone,

Two types of hypergeometric degenerate Cauchy numbers

open access: yesOpen Mathematics, 2020
In 1985, Howard introduced degenerate Cauchy polynomials together with degenerate Bernoulli polynomials. His degenerate Bernoulli polynomials have been studied by many authors, but his degenerate Cauchy polynomials have been forgotten.
