In this paper, well-posedness for non-autonomous second-order abstract Cauchy problems is investigated by a quasi-semigroup approach. This new approach completes the existing methods which are complex and require rigid conditions. The quasi-semigroup approach reduces the hyperbolic and parabolic conditions. The validity of this approach is confirmed by its equivalence to the fundamental solution. In the implementation, the non-autonomous second-order Cauchy problem is reduced to the first-order one, and the well-posedness follows the solution of the later problem in quasi-semigroup terms. As a

The study investigates various aspects, including the psychological effects of social media engagement such as self-esteem, social comparison, social interactions, perceived social support, and psychological well-being to promote positive mental health in the digital age. While much of the existing research has focused on adults and has yielded inconsistent findings regarding the relationship between digital technology use and mental health, recent large-scale studies have revealed only a minimal association between daily digital technology usage and adolescent well-being. This study used a to

The study investigates the influence of psychological factors on health protective behaviors and examines the role of consumer innovativeness in mediating these relationships. Utilizing a conceptual framework derived from established theories such as the health beliefs model, theory of planned behavior, and protection motivation theory, the research focuses on key psychological variables, including self-efficacy, perceived benefits, and behavioral beliefs, as independent variables, with health protective behaviors identified as the dependent variable. The systematic review synthesized findings

The review explores the intersection of influencer marketing and artificial intelligence (AI), highlighting how AI technologies are transforming influencer strategies across industries. Despite growing interest in AI-driven influencer marketing, gaps persist in understanding how these technologies impact brand awareness and consumer engagement. The review addresses key issues such as the effectiveness of AI-powered virtual influencers, data analytics integration, and the shift from traditional influencers to AI-enhanced campaigns. Its objectives include synthesizing current research trends and

The study aims to explore the intricate relationships between brain activity, behavioral processes, and decision-making using structural equation modeling (SEM) techniques. While existing research has advanced our understanding of these domains, gaps remain in synthesizing neurocognitive and behavioral factors in a unified framework. The primary objective of the study is to examine the neural mechanisms underlying decision-making and behavior, focusing on how brain function influences both cognitive and emotional decision processes. By integrating insights from neuroimaging, behavioral analysi
