Summary: Hierarchy provides unique opportunities for advanced material design with superior properties. However, its role in vibration mitigation and wave manipulation remains unclear. In this study, we demonstrate that designing non self-similar hierarchical geometries enables the creation of periodic structures supporting multiple highly attenuative and broadband bandgaps at different frequencies. The type of band gap mechanism is identified by examining the vibrational mode shapes and dispersion diagram of the unit cell.

Summary: Real-world optimization problems often require advanced algorithms. This study focuses on the petroleum product scheduling problem, which is a complex optimization task in the combinatorial problem category. The researchers leveraged bio-inspired approaches, specifically the Ant Lion Optimizer (ALO) and Chaotic Particle Swarm Optimization (CPSO), to improve the solution quality. The results showed significant reductions in cost and high constraint satisfaction rates. Further research on constraint handling methods and other bio-inspired computation approaches is recommended.

Summary: Inspired by natural hierarchical structures, this study proposes a new hierarchical honeycomb design methodology to overcome the shortcomings of conventional honeycomb structures. Through investigating the filling types, principles, and design basis of triangular, square, and circular holes at the microstructure level, a hierarchical honeycomb structure with superior mechanical properties is obtained. Simulation and experiment results show that the hierarchical honeycomb metastructures exhibit significantly improved overall mechanical properties compared with the conventional honeycomb structures, with the hierarchical honeycomb metastructures with circular holes having the best performance improvement.

Summary: Deterministic graphs have certain links between vertices, while probabilistic graphs only imply the possibility of links between vertices. Probabilistic data arises from uncertainties, leading to uncertain outcomes. Clustering probabilistic graphs poses challenges due to the probabilistic nature of computations.

Summary: Ant colony optimization (ACO) algorithms, inspired by the behavior of ants, are effective in solving complex problems in various domains, including water resources management. This study critically reviews the applications of ACO in hydrology and hydrogeology, such as reservoir operations, water distribution systems, and urban drainage design. Hybrid and modified ACO techniques are found to be more efficient than traditional ACO algorithms in terms of solution quality and cost efficiency. However, challenges remain in incorporating uncertainty and addressing issues of dimensionality, convergence, and stability. Further research is needed to explore the potential of ACO in these areas.

Summary: Inspired by natural materials, researchers propose a new category of hierarchical chiral structure to enhance its energy absorption capacity. The hierarchical chiral structure is constructed by replacing the central ring with a group of smaller rings connected by ligaments. Numerical analysis shows that hierarchical anti-tetrachiral structures exhibit a unique necking deformation mode at low impact speeds. Moreover, second-order anti-tetrachiral structures not only improve specific mass and volume energy absorption, but also effectively reduce peak stress compared to first-order structures. These findings contribute to the design of crashworthy auxetic components.

Summary: This study proposed a new bio-inspired hierarchical circular honeycomb (BHCH) with excellent energy absorption capacity. The experimental results showed that BHCH outperformed the conventional circular honeycomb in terms of energy absorption and had significantly higher relative stiffness, strength, and energy absorption than other cellular structures. The theoretical model analysis further demonstrated the enhanced energy absorption mechanism of BHCH.
