This paper presents the formulation and investigation for a stage-structured prey-predator system. We consider the stage- structure in both prey and predator populations, specifically dividing the population of prey into two distinct groups: immature prey and mature prey. We also divide the predator population into immature and mature groups. We assume that only immature predators are capable of attack, so they consume each immature and mature prey. Additionally, the rate of growth for immature prey based on the amount of mature prey, as immature prey does not have reproductive capability. We applied Holling Type I and Holling Type IV response functions to describe the consumption of immature and mature prey by immature predators, respec

In order to further confirm the security of SHA256 and protect it and increase its susceptibility to resist threats that it is exposed to in one way or another, its algorithm was developed by utilizing the modified skew tent map (MSTM). The developed SHA256 algorithm (D-SHA256) is distinguished by two essential features: less time and more enhanced security than its predecessor SHA256. This distinction arises from the strongly chaotic behavior and the highly randomness properties of the MSTM. Moreover, the proposed D-SHA256 algorithm consist of 32 rounds while preserving the randomness prope

This method is distinguished from other processes (physical and chemical) by its simplicity, cost-effectiveness, and low potential risks during preparation. Multiple techniques have been used to characterize and analyze ZrO2 NPs, including Fourier transform infrared and ultraviolet visible spectra, crystal size calculation by X-ray diffraction, scanning electron and atomic force microscopes, energy-dispersive X-ray, and Zeta potential. Kinetic stability of the ZrO2 NPs system, as indicated by the Zeta potential of -25.8 mV, suggests a long-term persistence and high surface charge.
... Show MoreOur work introduces the notion of -open set. This class of - open sets is not directly comparable to the categories of soft open, -closed. We demonstrate that the category of -open sets lies strictly between the class of -open sets and -open sets. Additionally, we investigate the connections that exist between -open sets along with other kinds of soft sets. Moreover, we provide several criteria that are sufficient for determining the equivalence between -open sets and every one of -open sets and -open sets. Also, according to our findings, the family of -open sets is a supra soft topology. Furthermore, we make it clear the correlation that exists between the respective categories of -open sets in a soft topological space and in its
