The present issue brings together a diverse collection of studies addressing contemporary challenges and innovations in logistics, environmental management, cosmetic science, food quality, and applied mathematics. Although the topics differ in scope and methodology, all contributions reflect the growing importance of technological advancement, optimization, and interdisciplinary research in solving modern scientific and practical problems.

The first article, “Digital Transformation in Logistics Customer Service of International Transport Enterprises”, explores digital transformation in logistic customer services, including automation, the use of artificial intelligence (AI), the Internet of Things, and the implementation of digital technologies for data analysis and customer service management. It examines their impact on the services in international transport companies and outlines the benefits of such a transformations, including more efficient, personalized service enabling continuous tracking, faster communication, and increased responsiveness. It also highlights some challenges, like technology implementation and limited access to data, that still need to be addressed.

The second article, “Integrated Port Environmental Process Maturity Model – Theoretical Framework”, presents the theoretical framework of the Integrated Port Environmental Process Maturity Model, which integrates the development of environmental process maturity in ports with measurable environmental performance outcomes. The model combines two previously independent approaches – Environmental Process Maturity and the Port Environmental Index – into a coherent system based on IoT-driven data and stakeholder engagement. The proposed solution supports the advancement of accountable, data-driven environmental management in smart ports.

The third article, “Nanostructures in Cosmetic Formulations”, presents the development of nanotechnology from its origins and discusses contemporary top-down and bottom-up methods to produce nanometric structures. Particular attention is devoted to the application of nanostructures in cosmetics, especially in terms of enhancing the skin penetration of active compounds, improving formulation stability, and achieving novel color effects. The paper provides a review of current knowledge regarding the properties of nanomaterials and their potential applications in modern cosmetic products.

The fourth article, “Storage Changes in the Health Potential of Manuka and Goldenrod Honey Due to Thermal Conditioning”, concerns the evaluation of changes in the health-promoting potential of manuka and goldenrod honeys during storage under different temperature conditions. The research work involved the analysis of the polyphenol content and antioxidant activity of the honeys.

The fifth article, “Optimal Time Moments in Uniform 1-Bullet Silent Duel with Scaled Exponentially Convex Accuracy”, deals with the finite 1-bullet silent duel, in which each of the two duelists shoots with exponentially convex accuracy through uniformly quantized time. The duel is a symmetric matrix game whose optimal value is 0, and each of the duelists has the same optimal behavior, whether it is in pure or mixed strategies. The conditions for the optimal time moment existence have been found, with numerical experiments confirming that the optimality can be manipulated by changing the accuracy factor that scales the payoffs. The results are applicable in systems under limited or censored communication with uncertainty, latency, and lucrative delayed actions.
