Bifurcations of a three-species prey-predator system with scavenger
Ain Shams Engineering Journal, 2023 In this paper, we explore the existence of fixed points, local dynamical characteristics at fixed points, the existence of bifurcation sets at fixed points, and bifurcations of a three-species discrete prey-predator system with the scavenger.

Shrinking Point Bifurcations of Resonance Tongues for Piecewise-Smooth, Continuous Maps
, 2008 Resonance tongues are mode-locking regions of parameter space in which stable periodic solutions occur; they commonly occur, for example, near Neimark-Sacker bifurcations.

Journal of Differential Equations, 1970 is to show that the degree at y of the map f for a fixed value of p is nonzero, and then use the invariance under homotopy of the degree to show that the degree has the same value as p is varied. To use this procedure it is necessary to prove that the degree is defined for the values of p considered. We consider (Section 2) the case in which the degree

Unleashing the Power of Machine Learning in Nanomedicine Formulation Development
Advanced Functional Materials, EarlyView.A random forest machine learning model is able to make predictions on nanoparticle attributes of different nanomedicines (i.e. lipid nanoparticles, liposomes, or PLGA nanoparticles) based on microfluidic formulation parameters. Machine learning models are based on a database of nanoparticle formulations, and models are able to generate unique solutions

Advanced Functional Materials, EarlyView.Dual‐cation site engineering unlocks stable and fast sodium storage in Na4VMn(PO4)3 cathodes. Li+ at Na2 suppresses Jahn‐Teller distortion, while K+ at Na1 expands ion channels, enabling synchronized V/Mn redox and quasi‐single‐phase kinetics. This atomic‐level strategy achieves ultralong cycling stability, high‐rate capability, and full cell viability

High Entropy Wide‐Bandgap Borates with Broadband Luminescence and Large Nonlinear Optical properties
Advanced Functional Materials, EarlyView.High‐entropy rare‐earth borates exhibit excellent nonlinear optical and broadband luminescence properties arising from multi‐component doping, chemical disorder, increased configurational entropy, and increased lattice and electronic anharmonicity. This formulation enabled us to obtain a large, environmentally stable single crystal with 3X higher laser‐
