Stability

In this work, we employ Moiré lattices generated in a high-order nonlinear material to investigate the existence of topological solitons under diverse geometries, which are controlled by the twisting angle of sublattices. The formation of solitons in both commensurate and incommensurate Moiré lattice configurations allows us to explore deeper into the impact of geometric transitions on soliton stability and localization.

In this work we studied the robust stability for implicit integro-dynamic equations on time scales with nabla derivative, which is considered as a generation of differential algebraic equations and implicit difference equations. We showed the reservation of exponential stability of these equations under small Lipschitz perturbations.

This study outlines a nanotechnology-based method to enhance its solubility and absorption of rosuvastatin. The process entails the formulation of rosuvastatin nanoparticles through a combination of precipitation and ultrasonic techniques. Rosuvastatin is initially dissolved in an organic solvent, such as acetone, and subsequently mixed with an aqueous phase containing stabilizers like Poloxamer 407 or PVP to induce precipitation. Ultrasound reduces particle size to 50-200 nm.

In this paper, the problem of exponential stability of linear time-delay systems with mixed discrete and distributed delays is studied. Based on an asymmetric Lyapunov–Krasovskii functional approach, sufficient conditions are derived in terms of linear matrix inequalities to guarantee the exponential convergence of the system state trajectories with a prescribed decay rate.

The problem of robust stability is investigated for a class of uncertain Hopfield-type neural networks with proportional delays. The existence and uniqueness of an equilibrium is first established using the homeomorphic mapping theorem. Then, by employing a modified Lyapunov–Krasovskii functional, a new criterion for the global asymptotic stability of an equilibrium point of the system is formulated.

In recent years, the understanding of processes on material surfaces has drawn considerable interest from scientists. The adsorption stage is important for further insights into surface interactions and photocatalytic reactions. In this study, we use density functional theory computations to investigate the adsorption of sulfamethoxazole (SMX) molecules on the rutile-TiO2 (001) surface (r-TiO2 ).

This paper investigates the problem of finite-time stability for discrete-time neural networks with sector-bounded neuron activation functions and interval-like timevarying delay. The extended reciprocally convex approach is used to establish a delay-dependent sufficient condition to ensure finite-time stability for this class of systems.

Probiotics are defined as microorganisms that, when administered in sufficient quantities, confer a health benefit on the host. As they are very susceptible to environmental conditions, solid dosage forms are used to increase their stability. Our study focuses on preparing an oily suspension containing L. acidophilus at a laboratory scale, oriented for use in infants and children under two years of age.

Amlodipine is a representative active ingredient of calcium channel blockers. In addition to the general advantages of calcium channel blockers in treating hypertension, amlodipine also effectively controls blood pressure for 24 hours and has no or just a little effect on neurohormonal activation, so it does not cause high blood pressure at the last dose. However, amlodipine has a plasma half-life of between 30 and 40 hours, slowing the drug's action duration.
