DYNAMICS OF A PREY-PREDATOR MODEL WITH ALLEE EFFECTS AND HOLLING TYPE IV FUNCTIONAL RESPONSE: LOCAL STABILITY AND NUMERICAL EXPLORATION OF BIFURCATIONS

Barekeng
This study presents a prey-predator model incorporating the Allee effect and Holling Type IV Functional Response. The model identifies three equilibrium points: the zero-equilibrium, the predator extinction equilibrium, and the positive equilibrium ...

Impact of the fear and Allee effect on a Holling type II prey–predator model

Advances in Difference Equations, 2021
In this paper, we propose and investigate a prey–predator model with Holling type II response function incorporating Allee and fear effect in the prey. First of all, we obtain all possible equilibria of the model and discuss their stability by analyzing ...

Sulfonated‐TiO2 Nanorod–Reinforced PEO Composite Solid Electrolytes for High‐Voltage Solid‐State Lithium Metal Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study introduces a high‐performance composite solid electrolyte (CSE) utilizing actively sulfonated TiO2 (STiO2) nanorods within a PEO matrix. The 1D ceramic network chemically promotes LiTFSI dissociation and creates continuous fast‐hopping pathways for Li+ ions, delivering an ionic conductivity of 1.5 × 10−4 S cm−1 at room temperature, an ...

Interplanetary frontiers: terraforming from an invasion science perspective

Oikos, EarlyView.
The pursuit of a multi‐planetary existence represents one of humanity's greatest frontiers. If applied justly, it offers an opportunity to extend its civilization's lifespan amid escalating sustainability crises on Earth. One approach increasingly gaining traction is terraforming, a hitherto theoretical ecological and evolutionary experiment revolving ...

Von Bertalanffy's growth dynamics with strong Allee effect [PDF]

, 2012
Von Bertalanffy's model is one of the most popular differential equation used in order to study the increase in average length or weight of fish. However, this model does not include demographic Allee effect.

Stability and Bifurcation Analysis of a Predator–Prey Model With Generalized Allee Effect on the Prey Population

Journal of Mathematics
This research describes a predator–prey system that takes into account the generalized Allee effect, aiming to derive general conclusions applicable to specific Allee effect functions through the use of a generalized function.

Surface Engineering of Ti3C2Tx MXenes via Silanol Functionalization for Improved Electrochemical Performance

Small, EarlyView.
This study explores the covalent functionalization of Ti3C2Tx using 5,5′‐bis(triisopropoxysilyl)‐2,2′‐bipyridine in different solvents, revealing that only m‐xylene enables effective covalent bonding, ensuring structural stability and preventing layer swelling.
