This study uses a convenience sampling method. The results showed that online anxiety had a positive effect on self-efficiency, coping had a positive effect on self-efficiency, and coping had a moderator in this relationship. Research results contribute to the theoretical basis of the relationship between online anxiety, coping, and self-efficiency.

The composite girder, which combines a steel beam with an ultra-highperformance concrete (UHPC) slab, has gained significant attention in recent years as a new type of bridge structure. However, accurately estimating the bending capacity of such girders remains a challenge, as practical methods are limited. In this article, the authors propose a theoretical approach based on the Euler-Bernoulli beam theory to determine the bending capacity of composite girders.

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 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.

This paper presents a theoretical study that describes the fiber bridging mechanism under tensile stress using a closed-form analytical function. This proposed analytical model allows estimating the stress at a crack opening where the fiber orientation is represented by a Gaussian-like periodic distribution function.

Non-compete agreements are established by employers and employees to protect the employer’s trade secrets. These agreements are governed by the laws of many countries around the world. However, in Vietnam, the current law does not have clear provisions to regulate this issue. In this article, the author introduces the doctrine of inevitable disclosure that can be used as a theoretical basis for legislators to officially recognize the validity of the non-compete agreements in the near future.

The research objects are the Law on Enterprise Income Tax, the Law on Value-Added Tax, decrees and circulars guiding these laws. The methods used in this study are: Desk Research and Theoretical Research. Results of this study show that the legal framework of tax incentives for startups is incomplete. Besides, results of this study also show that the legal framework of tax incentives for startups still faces many limitations and problems, which requires the need to complete the law.
