Advancements in the management of gastrointestinal and hepatic diseases have been possible through a better understanding of their underlying mechanisms. For instance, the development of direct-acting antivirals has been achieved through improved knowledge of HCV infection. The incidences of peptic disease and stomach cancer have been reduced through efforts to decrease H. pylori infection, increased use of proton-pump inhibitors, and greater accessibility to gastroscopies. Targeted therapies such as anti-TNF, anti-IL12/23, and anti-JAK have been developed based on an understanding of the inflammatory pathways involved in inflammatory bowel disease. Finally, increased knowledge of the microbiota will lead to novel clinical applications beyond gut-related diseases.

The normative development of children's social, emotional, and academic adjustment stems from sources including both family and peer groups. Parent-child and peer interactions have unique and significant implications for children, and these social relationships serve as a foundation for feelings of security and belonging. During the socialization process in at-home and in-school contexts, children display a wide variety of social behaviors. However, several issues require further exploration. For example, what are the different causal relations that might underlie children's social behaviors? What is the trajectory of these social behaviors at different developmental stages? Can we establish the neural basis for these social behaviors using advanced techniques? In light of these premises, this reprint aims to advance the literature on the development trajectory of children's social behaviors and their cognitive neural mechanisms. The research in this reprint elucidates a broad range of social behaviors and illustrates relevant empirical evidence, new methodological concerns, and future directions in this field.

Structural health monitoring (SHM) and non-destructive testing (NDT) have gained significant importance for civil, mechanical, aerospace, and offshore structures. Nowadays, we can find SHM and NDT applications being used on various structures with very different requirements. However, the practical implementation of strategies for the detection of structural damage to real structures outside of laboratory conditions is always one of the most demanding tasks for engineers. Moreover, the processing and interpretation of the massive amount of data generated through the long-term monitoring of large and complex structures (e.g., bridges, buildings, ships, aircrafts, wind turbines, pipes, etc.) has become an emerging challenge that needs to be addressed by the community. This Topic brings together the most established as well as newly emerging SHM and NDT approaches that can be used for the detection and evaluation of defects and damage development in large-scale or full-scale structures. After a strict peer-review process, 44 papers were published, which represent the most recent progress of SHM and NDT methods/techniques for aerospace, civil, mechanical, and offshore infrastructures.

The purpose of this reprint is to present current research on identifying and supporting giftedness and talent in schools all over the world. This reprint contains 19 articles from differing international contexts: Australia, Austria, Finland, France, Greece, Norway, Scotland, Sweden, Turkey, and the USA. By sharing differing approaches with one another, we can learn and be inspired as to how to deliver quality educational experiences for gifted children and students. Diverse approaches to identification include broad (even 'fuzzy'), multi-categorical, and curriculum-specific opportunities for talent to emerge within enrichment programs. Diverse approaches to gifted education support include differentiated teaching or curriculum content, such as the use of transdisciplinary, holistic education; acceleration; ability-grouping; special programs; and enrichment opportunities. Alongside these considerations are why we engage in gifted education, specifically the needs and educational rights of children and students. We take a holistic approach to education in schools and early childhood education that includes cognitive, emotional, social, and moral domains concerning giftedness and talents. This means that all aspects of a gifted learner are important, not just their academic achievements. We increasingly find that gifted child and student well-being is tied to the identification and support they receive in schools and early childhood services.

In recent years, there has been a growing interest in the geoenvironment, with concepts like "geosites", "geoparks", and "geodiversity" becoming integral to the local economic and cultural development of various areas.

Due to the increase in population worldwide, there is an urgent need to estimate natural hazards more efficiently. A crucial aspect of this challenging task is the mitigation of the risk of earthquakes. The occurrence of earthquakes is an inherently complex phenomenon that is manifested in the nonlinear dynamics that form the process of earthquake generation. Earthquakes interact over a wide range of spatial and temporal scales to generate new events; meanwhile, the coupling of stress interactions with other aseismic processes, such as fluid flow, poroelastic effects, and aseismic slip, may further reduce the frictional strength of faults, triggering more earthquakes. As such, earthquakes are considered a critical phenomenon, exhibiting nonlinearity, self-organized criticality, scaling, clustering, fractal/multifractal structures, and long-range interactions. The analysis of earthquake phenomena in the light of complexity theory is thus ubiquitous, and mathematical tools arising from statistical physics offer a consistent theoretical framework with which to better understand the occurrence of earthquakes. With the significant generation of new data in recent years, these modern tools may provide novel and substantial insights into the physics of earthquakes, with the ultimate aim being to mitigate the risk of earthquakes more effectively.

In a world dealing with the widespread impact of heavy metals on our environment, it is crucial to delve deep into the subject and develop effective strategies.

It is crucial that we strengthen existing structures worldwide, especially in earthquake-prone areas. Recent earthquakes have highlighted the inadequacy of many existing structures, which have been damaged from previous powerful earthquakes and have been designed without code provisions or according to old code provisions that are now obsolete. Furthermore, the majority of existing buildings in low- and middle-income countries have been constructed using substandard materials and without application of code provisions; therefore, the structural vulnerability in these areas is highly concerning.Recently, there has been enormous development in novel construction materials that could be effectively utilised to protect existing structures and to enhance structural resilience. This Special Issue provides an overview of the latest scientific advancements in the development of novel technologies for durable earthquake-resistant Reinforced Concrete (RC) structures. These studies are focused on the development and application of innovative repair and strengthening techniques using novel composite and high-performance materials for the structural performance improvement and improved durability of existing RC structures.
