Article Abstract
In this paper we consider the nearness symmetric solution of the matrix equation AXB = C to a given matrix [Formula: see text] in the sense of the Frobenius norm. By discussing equivalent form of the considered problem, we derive some necessary and sufficient conditions for the matrix [Formula: see text] is a solution of the considered problem. Based on the idea of the alternating variable minimization with multiplier method, we propose two iterative methods to compute the solution of the considered problem, and analyze the global convergence results of the proposed algorithms. Numerical results illustrate the proposed methods are more effective than the existing two methods proposed in Peng et al. (Appl Math Comput 160:763-777, 2005) and Peng (Int J Comput Math 87: 1820-1830, 2010).

Mental well-being and work capacity: a cross-sectional study in a sample of the Swedish working population.
BMC Public Health
September 2025
Department of Sociology and Work Science, University of Gothenburg, Gothenburg, Sweden.
Background: Mental health problems are common in the working-age population. More knowledge is needed on how to support work participation and reduce sickness absence. The objective of the study was to estimate the distribution of mental well-being and work capacity in women and men in a working population and assess the association between mental well-being and work capacity, while adjusting for sociodemographic characteristics, health status, and working positions.

A series of enlarged sublingual glands (SLG) that affected dental implantation procedures and prosthodontic rehabilitation is presented, along with their management. All patients were referred by their treating prosthodontists due to swelling in the floor of the mouth that caused difficulties in fitting dental implants or rehabilitation. Sixteen patients aged 27-80 years (12 female, 4 male), treated between 2015 and 2022, were included in this study.

Traditionally, clinical devices are designed, tested and improved through lengthy and expensive laboratory experiments and clinical trials [1]. More recently, computational methods have allowed for rapid testing, speeding up the design process and enabling far more complete searches of design space. While computational models cannot fully capture the complexities of biological systems, they provide valuable insights into crucial underlying mechanisms, such as the effects of fluid-structure interactions (FSIs).

Aqueous batteries have become a prospective future energy storage system because of their low coefficient of cost and stability. However, their lower energy density limits their applications. Ammonium ions (NH) have a small hydration radius and light molar mass, and aqueous ammonium ion batteries (AAIBs) are anticipated for solving the inherent low-energy density problem of aqueous batteries.
