Although many methods well-performed on the DEED problem, most of them fail to achieve expected results in practice due to a lack of effective trade-off mechanisms between the convergence and diversity of non-dominated optimal dispatching solutions. To address this issue, a new multi-objective solver called Multi-Objective Golden Jackal Optimization (MOGJO) algorithm is proposed to cope with the DEED problem. The proposed algorithm first stores non-dominated optimal solutions found so far into an archive. Then, it chooses the best dispatching solution from the archive as the leader through a selection mechanism designed based on elite selection strategy and Euclidean distance index method. This mechanism can guide the algorithm to search for better dispatching solutions in the direction of reducing fuel costs and pollutant emissions. Moreover, the basic golden jackal optimization algorithm has the drawback of insufficient search, which hinders its ability to effectively discover more Pareto solutions. To this end, a non-linear control parameter based on the cosine function is introduced to enhance global exploration of the dispatching space, thus improving the efficiency of finding the optimal dispatching solutions. The proposed MOGJO is evaluated on the latest CEC benchmark test functions, and its superiority over the state-of-the-art multi-objective optimizers is highlighted by performance indicators. Also, empirical results on 5-unit, 10-unit, IEEE 30-bus, and 30-unit systems show that the MOGJO can provide competitive compromise scheduling solutions compared to published DEED methods. Finally, in the analysis of the Pareto dominance relationship and the Euclidean distance index, the optimal dispatching solutions provided by MOGJO are the closest to the ideal solutions for minimizing fuel costs and pollution emissions simultaneously, compared to the latest published DEED solutions.</p></div>","PeriodicalId":614,"journal":{"name":"Journal of Bionic Engineering","volume":"21 3","pages":"1541 - 1566"},"PeriodicalIF":4.9,"publicationDate":"2024-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140636839","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the micro-nanostructures on the surfaces of superhydrophobic coatings are fragile under external forces, resulting in reduced durability. Therefore, mechanical strength and durability play a crucial role in the utilization of superhydrophobic materials. In this study, we employed a two-step spraying method to fabricate superhydrophobic FEVE-based coatings with exceptional mechanical durability, utilizing fluorinated TiO₂ nanoparticles and fluorinated Al₂O₃ microwhiskers as the fillers. The composite coating exhibited commendable non-wetting properties, displaying a contact angle of 164.84° and a sliding angle of 4.3°. On this basis, the stability of coatings was significantly improved due to the interlocking effect of Al₂O₃ whiskers. After 500 tape peeling cycles, 500 sandpaper abrasion tests, and 50 kg falling sand impact tests, the coatings retained superhydrophobicity, exhibiting excellent durability and application capability. Notably, the ice adhesion strength on the coatings was measured at only 65.4 kPa, while the icing delay time reached 271.8 s at -15 °C.

However, the present work investigated the microindentation behavior on fresh and heat-treated nacres from two orthogonal directions, and the results demonstrate that both hardness value and damage tolerance can remain almost unchanged on the cross-section with the organic matrix degeneration, despite a significant deterioration on the platelet surface. Theoretical analyses suggest that the anisotropic response of indentation behavior to heat treatment in nacre is primarily caused by its structural orientation. Specifically, compared with a single layer of irregular interplatelet interfaces in cross-sectional specimens, the multiple layers of parallel interlamellar interfaces in in-plane specimens exhibit a much greater ability to impede indenter-triggered destruction, and heat treatments would reduce the in-plane hardness but nearly have no effect on the cross-sectional hardness. Moreover, the deeper embedding of platelets in cross-sectional specimens enhances their resistance to interface cracking caused by organic matrix degradation at high temperatures, leading to a reduced sensitivity to damage. Therefore, the indentation behavior of nacre shows different tendencies in response to variations in the organic matrix state along normal and parallel directions.</p></div>","PeriodicalId":614,"journal":{"name":"Journal of Bionic Engineering","volume":"21 3","pages":"1453 - 1464"},"PeriodicalIF":4.9,"publicationDate":"2024-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140612322","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper proposes an Ameliorated Pathfinder Algorithm called APFA to solve complex engineering optimization problems. Firstly, a guidance mechanism based on multiple elite individuals is presented to enhance the global search capability of the algorithm. Secondly, to improve the exploration efficiency of the algorithm, the Logistic chaos mapping is introduced to help the algorithm find more high-quality potential solutions while avoiding the worst solutions. Thirdly, a comprehensive following strategy is designed to avoid the algorithm falling into local optima and further improve the convergence speed. These three strategies achieve an effective balance between exploration and exploitation overall, thus improving the optimization performance of the algorithm.

To address the challenges, constructing a bioinspired interface that mimics the hierarchical structure of bone tissue can enhance the cellular functions of cells. In this context, Hollow Mesoporous Silica Nanoparticles (HMSNs), renowned for their unique physicochemical properties and superior biocompatibility, offer a promising direction for this research. In this research, the initially synthesized HMSNs were used to construct a “hollow-mesoporous-macroporous” hierarchical bioinspired coating on the pTi surface through the Layer-by-Layer technique. Simultaneously, diverse morphologies of coatings were established by adjusting the deposition strategy of PDDA/HMSNs on the pTi surface (pTi-HMSN-2, pTi-HMSN-4, pTi-HMSN-6). A range of techniques were employed to investigate the physicochemical properties and regulation of cellular biological functions of the diverse HMSN coating strategies. Notably, the pTi-HMSN-4 and pTi-HMSN-6 groups exhibited the uniform coatings, leading to a substantial enhancement in surface roughness and hydrophilicity. Meantime, the coating constructed strategy of pTi-HMSN-4 possessed commendable stability. Based on the aforementioned findings, both pTi-HMSN-4 and pTi-HMSN-6 facilitated the adhesion, spreading, and pseudopodia extension of BMSCs, which led to a notable upsurge in the expression levels of vinculin protein in BMSCs. Comprehensive analysis indicates that the coating, when PDDA/HMSNs are deposited four times, possesses favorable overall performance. The research will provide a solid theoretical basis for the translation of HMSN bioinspired coatings for orthopedic implants.</p></div>","PeriodicalId":614,"journal":{"name":"Journal of Bionic Engineering","volume":"21 3","pages":"1427 - 1441"},"PeriodicalIF":4.9,"publicationDate":"2024-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140573490","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
