Food security is increasingly under threat from climate change, population growth, and resource limitations. The review explores the role of innovative agricultural technologies in addressing these challenges, with a focus on ensuring sustainable global food systems. Despite significant advancements in precision agriculture, climate-smart practices, and food systems modeling, gaps persist in integrating these technologies effectively across diverse socio-economic and geographic contexts. Issues such as unequal access, high implementation costs, and limited interdisciplinary coordination hinder

Structural equation modeling (SEM) has become a fundamental analytical tool across diverse disciplines, offering a robust framework for testing complex relationships. However, various assumptions underpinning SEM, including model fit, measurement invariance, missing data treatment, and the validity of causal inferences, remain subjects of debate. Despite significant advancements in SEM methodologies, gaps persist in addressing the reliability of parameter estimates, sensitivity to model modifications, and the integration of alternative analytical approaches. The study aims to critically examin

The digital age has transformed communication, with social media platforms playing a central role in connecting individuals worldwide. However, the widespread adoption has also led to concerns over social media addiction and its impact on mental health, particularly in Malaysia. The study investigates how psychological factors, social comparison and social support affect mental health and well-being through social media usage. Adopting a positivist methodology, the study surveyed 400 Malaysian participants, examining the relationships between social media engagement, social comparison, and per

The rapid growth of eHealth technologies has transformed global healthcare delivery, enhancing patient care, access, and efficiency, particularly in underserved regions. This review synthesizes studies on AI-driven diagnostics and telemedicine, highlighting their potential impact on healthcare systems. Despite these advancements, challenges such as data privacy, ethical issues, and infrastructural barriers remain, along with global disparities in eHealth adoption. The review adopts a systematic approach, analyzing studies from regions like Tanzania, Poland, Spain, and Malaysia, offering a glob

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
