Summary: Static and dynamic self-organized patterns were observed in dielectric barrier discharge through numerical simulation. The static pattern consists of regularly distributed standing discharge channels/filaments, and its morphology depends significantly on discharge parameters such as electrode size and voltage. The interaction between the filaments is proved to be electrostatic repulsion. The introduction of an external flow field breaks the stability of the pattern, resulting in the formation of a quasi-static pattern with a displaced filament or a dynamic pattern with directional moving filaments. The motion of the filaments is believed to be caused by the thrust from the flow, which can also be explained at the microscopic level by the transfer of momentum from neutral background atoms to species through collision. Moreover, the filaments may exhibit particle-like behaviors such as collision, vanishment, and generation under the influence of the flow.

Summary: Formation of self-organized nanodiamond ring structures is reported due to dynamical heterogeneity in super undercooled carbon, created by nanosecond laser melting of amorphous carbon layers. Diamond tetrahedra self-organize to lead to the formation of string and ring structures, on which nanodiamonds nucleate and grow. Denser ring structures are formed in Q-carbon due to higher undercooling and enhanced diamond nucleation, showing larger average size and higher growth velocities compared to homogeneous nucleation.

Summary: This study examines the transition from transgression to regression in Holocene barrier systems in southeastern Australia through chronostratigraphic description of three barrier systems. The results indicate that the Holocene turnaround transition occurred between 8400 and 7000 years ago and was preserved at the landward margin of these three strandplains, with morphostratigraphic differences primarily influenced by sea level, sediment supply, and antecedent topography.

Summary: The formation of porous structures during metal electrodeposition not only provides new ideas for preparing advanced metal materials, but also determines the product defects in industrial electrodeposition processes. This study discovered the periodic self-organization behavior of porous copper at the initial stage of industrial large-current electrodeposition. The findings suggest the important contribution from intrinsic self-organization dynamics of intermediate to the formation of porous metal materials with high activity or surface area in industrial scale.

Summary: The use of UAVs in environmental applications, particularly in monitoring coastal areas with rapid morphological changes and high rates of sediment transport, has been proven to be cost-effective and easy to use. This paper presents three case studies showcasing the advantages of using UAVs for high resolution and accurate survey and monitoring, which include assessing coastal landforms and associated processes. The results demonstrate that the combination of quality drone-sensed data and precise topographic control enables quantitative estimates useful in assessing the impacts of natural processes involving both human and natural assets.

Summary: The paper reviews recent studies on sedimentary archives of coastal inundation events in Morocco. The authors identified 20 sites with traces of coastal inundation deposits along the Atlantic coast, while the Mediterranean side remains understudied. A major issue is the lack of chronological data for most of these deposits, which hinders the determination of the return period of these events. Understanding the past occurrences can help in preventing similar natural hazards.

Summary: The field of correlated disordered media has emerged in the last few decades, providing new perspectives for theoretical modeling and material fabrication. The efficient design of structures with controlled spatial correlation is a central challenge in this field. Existing techniques rely on nonconvex functions and stochastic methods for exploring vast design spaces. In this work, a generative technique based on Alan Turing's morphogenesis theory is proposed for designing correlated disordered materials. Inspired by living organisms, this technique uses simple local interactions to guide the self-organization of generated medium.

Summary: This study documents the potential tsunami deposits preserved in a mangrove environment in western Mindanao Island and provides geological evidence of the 1976 Moro Gulf tsunami, the worst tsunami disaster in the Philippines. The sedimentological characteristics of potential tsunami deposits in three coastal sites were analyzed and compared to describe the preservation of washover deposits in different coastal systems. The study highlights essential information and lessons for future researchers of washover deposits in the Philippines and serves as fundamental information in understanding the processes and mechanisms of extreme wave events in this region.

Summary: In this study, the authors explore the formation of regular patterns in ecosystems and geomorphology, proposing competition as a complementary mechanism contributing to spatial self-organization. By studying the patterned landscape of Big Cypress National Preserve in South Florida, they demonstrate that competition among pattern elements, rather than scale-dependent feedback, leads to spatial regularity such as evenly spaced limestone depressions.

Summary: Research shows that the characteristics of sediment deposits from geohazard events in built environments exhibit systematic similarities and differences compared to those in unbuilt environments. The built fabric in the environment exerts a fundamental control on the form of large deposits. Considering the influence of built fabric on the morphodynamics of flow-driven geohazards is a feasible step towards improving forecasts of hazard impacts and reducing disaster risks.

Summary: Efforts to reduce disaster risk have been largely ineffective, with trends such as growing economic costs of disasters, social inequity, environmental degradation, and resistance to policy interventions indicating the presence of a system trap. This system trap, which the author terms the disaster trap, involves self-reinforcing feedbacks leading to an undesirable state with negative consequences that compound over time. Understanding and addressing these traps as dynamic systems is crucial for effectively reducing disaster risk.
