Existence of Normalized Solutions of a Hartree–Fock System With Mass Subcritical Growth

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In this paper, we are concerned with normalized solutions of a class of Hartree‐Fock type systems. By seeking the constrained global minimizers of the corresponding functional, we prove that the existence and nonexistence of normalized solutions.

Acetylcholinesterase Inhibition and Antioxidant Activity of DHA‐Disubstituted Phospholipids

Molecular Nutrition &Food Research, EarlyView.
1,2‐Di‐DHA‐PC phospholipids in nutraceutical form may cross the blood‐brain barrier and inhibit acetylcholinesterase (AChE) activity, with an efficacy similar to galantamine. This suggests their potential as neuroprotective agents in the treatment of Alzheimer's disease.

Influence of Velocity Feedback Time Delay on the Nonlinear Dynamic Characteristics of Maglev Trains Under Unsteady Aerodynamic Forces

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Time delays frequently arise in active control systems due to sensor sampling, signal transmission, and actuator response, making their effects on system dynamics non‐negligible. This paper investigates how velocity feedback time delay influences the nonlinear dynamic characteristics of a maglev train subjected to unsteady aerodynamic forces ...

Application of Surrogate Modeling in Stochastic Analysis of an Ogee Spillway Structure

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT This study investigates the hydraulic performance of an Ogee spillway under varying flow rate conditions, gate opening heights, and spillway widths. Numerical simulations using Flow‐3D, incorporating the (k‐ε) turbulence model and Large Eddy Simulation (LES), were employed alongside surrogate models using MATLAB codes and LP‐TAU to predict ...
