In recent research, fear, refuge, and harvesting have been highlighted, but their combined
impact must also be explored. We investigate the combined effects of these three …

The problem of the research is to find medical images of purity, high quality and free of
impurities, which contributes to enabling doctors to obtain the results of analyzing the health …

Classification is of great importance in the field of image processing, and convolutional
neural networks (CNNs) have achieved great success in this field. Although CNN has …

One of the central concerns in ecology is assessing the impact of environmental changes,
such as global temperature shifts, on the dynamic interactions between predators and prey …

A generalized delay stage structure prey-predator model with fear effect and prey refuge is
considered in this paper via introducing fractional-order and fear effect induced by immature …

In this work, the sufficient conditions for uniformly persistence of a food chain prey-predator
model with prey refuge and harvesting have been found. By creating suitable Lyapunov …

In this paper, the dynamical behaviour of an {epidemiological system} has been
investigated. A stage-structured prey-predator model includes harvest and refuge for only …

The cheif aim of the present investigation is to develop Leslie Gower type three species food
chain model with prey refuge. The intra-specific competition among the predators is …
