Studied conditions

The study of second-order optimality conditions is one of the most important topics in optimization theory and attracting the attention and interest of many authors. In this paper, we introduce a novel solution concept called “essential local efficient solutions of second-order” for nonconvex constrained multiobjective optimization problems.

Stictic acid, a depsidone in many lichen species, is a potentially bioactive compound. Derivatives of stictic acid were synthesised by halogenation or esterification. However, the effects of these conditions on the decomposition of stictic acid have yet to be studied. Hence, the modification of stictic acid was investigated using an AlCl3 catalyst and dimethylformamide solvent.

This study investigates the potential of using watermelon rind, a commonly discarded byproduct, to produce fermented beverages. Watermelon rind, which constitutes 30% of the fruit's weight, is rich in fiber and amino acids, offering significant nutritional benefits. The aim was to optimize the fermentation process by adjusting factors such as total soluble solids, pH, yeast concentration, and fermentation time to enhance both alcohol production and the sensory qualities of the beverage.

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.

This article studies developing an algorithm called KalmanEMD with the combination of Kalman filter and empirical mode decomposition for processing this signal type. The algorithm is applied in 6 data sets measuring the shockwave pressure of underwater explosions by PCB W138A05 sensors with the same condition that 184 grams of A-IX-2 explosive is detonated underwater.

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.

In this study, we developed a continuous flow method to synthesize arylhydroxylamines by a novel nitroreductase from Geodermatophilus obscurus, which shows high activity and chemo-selectivity in converting nitroarenes to N-Arylhydroxylamines (>99%) under mild condition. This method therefore provides a novel avenue to synthesis N-hydroxylamine.
