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.

Astaxanthin (AST) and pycnogenol (PYC) are natural bioactive compounds commonly used in pharmaceuticals and functional foods due to their highly antioxidant activity and potential health benefits. However, the widespread application of astaxanthin is hindered by its poor water solubility and highly unsaturated structure. In this study, nanoparticles co-delivering astaxanthin and pycnogenol (NAP) were fabricated to enhance the dispersibility, stability, and bioavailability of astaxanthin.

This article studies the influence of modal parameters on the accuracy of the GeB method used to identify the viscous damping ratios in MDOF systems. The results compared with the formulas based on the half-power bandwidth (HPB) method show that the GeB method has good efficiency and a wide identification range.

This study employs the tight-binding density functional method GFN1-xTB to investigate the structural and electronic properties of TiO2-ZnO and TiO2-ZnO composite materials modified by Li, Na, K, and Fe metals. Computational analyses reveal the formation of weak covalent bonds between the TiO2 and ZnO components within the composite system. Doping TiO2-ZnO with metals induces significant alterations in the electronic structure, particularly in terms of ionization energy and global electrophilic index.

The gut microbiota plays a crucial role in food digestion, enhances the host's immune system, and against pathogens. Numerous studies have been conducted on the microbiota of insects in general and honeybees in particular. However, studies have primarily focused on adult honeybees, with fewer studies dedicated to larvae. Despite being within the hive, honeybee larvae still possess their distinct microbiota.

Many environmental factors have been reported to be associated with the risk of developing multiple sclerosis (MS), such as lack of exposure to sunlight, vitamin D deficiency, obesity, smoking, and infectious mononucleosis. Vitamin D deficiency has been shown to play a role in immune system function and may increase the risk of developing MS, although there are many confounding factors and inconsistent results. In this report, we evaluated vitamin D levels in newly diagnosed MS patients to determine the need for vitamin D supplementation.

This paper presents a method for establishing the exact receptance function of a tapered axially functionally graded (AFG) beam with nonlinear ratios of properties using the Adomian method. In current papers, the Adomian method was applied for linearly tapered beams where the geometric series was used conveniently.

In this work, the free vibration analysis of Timoshenko microbeams made of the Functionally Graded Material (FGM) on the Winkler–Paternak elastic foundation based on the Modified Coupled Stress Theory (MCST) is investigated. Material characteristics of the beam vary throughout the thickness according to the power distribution and are estimated though Mori–Tanaka, Hashin–Shtrikman and Voigt homogenization techniques.

This thesis intends to develop application-level access control models to address several major security issues in enterprise environments. The first goal is to provide simple and efficient authorization specifications to reduce the complexity of security management. The second goal is to provide dynamic access control for Web service applications. The third goal is to provide an access control framework for Semantic Web services. In this thesis, an Authorization-Function-Based Role-based Access Control (FB-RBAC) model is proposed for controlling enterprise systems at the application level.

This research is an investigation into the phrase 'intermediate landscape' and tests this concept in the re-development of the Sanya waterfront, China. The phrase is based on the 'missing link' in the current disconnection between the landscape and urban development in Sanya city. If the landscape is considered as a connection across scales and urban systems rather than an isolated system, then how can landscape affect the structure and function of urban development?
