The thermal properties of CdTe, CdSe, and CdS compounds are determined from the acquired thermogravimetric (TG) and differential thermogravimetric (DTG) analysis.

The thermal degradation kinetics of all samples is assessed through the application of non-isoconversional Broido, Coats–Redfern, and Piloyan–Novikova relations.

The outcomes suggest that CdTe undergoes more pronounced weight loss with degradation initiated earlier than CdS and CdSe.

Building upon the structure of fish school, a collective model of streamlined forms is established. These streamlined collective models are arranged on a plane, and the study investigates the impact of various streamlined collective structures on planar resistance. By changing the spacing of the streamline collective model and flow field velocity, the drag reduction rules of different models at different flow rates are obtained. Through flow field analysis, the mechanism through which streamlined collective models achieve drag reduction on a flat surface is revealed. The research indicates that the streamlined collective models reduce total resistance by diminishing the viscous drag on the flat plate. The drag reduction effect generally decreases and then increases as the lateral spacing of the streamlined collective model increases. The maximum drag reduction rate can reach up to 8.63%.

The amylopectin-modified mortar enhances its compressive strength by 1.68 times compared to the reference mortar. The amylopectin-modified mortar improves its mechanical properties without compromising water absorption and porosity, thus preserving the breathability of the restoration mortar. Amylopectin enhances the hydrophobic property of NHL mortar, forming an outer layer that is resistant to water and salt deposition. The modified mortar’s moisture-holding capacity improves carbonation and reduces drying shrinkage. The polysaccharides of amylopectin enhance the carbonation, regulate the growth of calcite crystals, and result in a denser microstructure, leading to enhanced strength gain.

Within the realm of statistical physics and complex systems, optimal control theory emerges as a fundamental and indispensable framework for formulating these preventive measures. Simultaneously, networked reaction–diffusion systems have emerged as essential tools for comprehensively understanding the complex dynamics of infectious disease transmission. These systems integrate diverse and essential aspects of human spatial behavior, including habitat distribution, small-world network properties, and large-scale movement patterns, key elements in the in-depth study of complex systems. Consequently, there is a rapidly burgeoning interest in exploring the optimal control problems associated with these reaction–diffusion equations. However, study on the complex dynamics and optimal control of network infectious disease models remains limited, especially in the context of higher-order networks that introduce additional layers of complexity. This article reviews recent advances in the dynamics and optimal control of networked reaction–diffusion systems, underscoring their vital and irreplaceable role in disease prevention and control. We deep dive into the dynamics within both regular and complex networks, investigating how network structure and diffusion parameters influence disease transmission. Furthermore, we comprehensively expound upon several optimal control strategies, including sparse and local optimal control, and propose a comprehensive approach that integrates both reaction and diffusion terms. Finally, we outline future research directions, emphasizing the great potential of integrated strategies to effectively tackle spatial disease transmission, thereby providing a solid theoretical foundation and practical guidance for related fields within the expansive domain of statistical physics and complex systems.</div></div>","PeriodicalId":404,"journal":{"name":"Physics Reports","volume":"1111 ","pages":"Pages 1-64"},"PeriodicalIF":23.9,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143144477","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
