The study of combat system-of-systems architecture design (CSAD) is the basis of cross-domain cooperative activities, and cross-domain cooperative activities are the basis for realizing mosaic warfare. This paper proposes a mixed-integer programming model for CSAD problem-oriented mission planning and an improved evolutionary algorithm for solving the model. The goal of the CSAD problem is to design the architecture of the combat system-of-systems which is evaluated based on the performance of combat tasks. Therefore, it is necessary to model the mission planning problem, and the model should fit the characteristic of the combat system-of-systems architecture. An improved evolutionary algorithm to solve the mission planning problem is proposed. To improve the solution effect, the task planning algorithm based on predecessor strategy was designed. To further improve the performance of mission planning algorithm, an elite retention strategy was proposed, so that it can retain more good individuals and delete more poor individuals during the evolution of the algorithm, so that the solution process of the planning solution converges as soon as possible. The simulation experiments show that the proposed method can solve the CSAD problem well and has a significant improvement effect compared with the comparative neighborhood search algorithm and two heuristic algorithms. © 2022 IEEE.

The Yangtze River Estuary and the adjacent inner shelf are significant areas for both the burial and degradation of terrestrial organic matter (OM). However, the impact of hydrodynamics on the degradation of different types of organic compound classes has not been fully elucidated. This study measured dual carbon isotopes (δ¹³C, Δ¹⁴C) of organic compound classes [total hydrolysable amino acids (THAAs), total lipids, humic acids (HAs) and acid-base insoluble OM] in both surface and core sediment samples to evaluate the influences of hydrodynamic processes on the fates of organic compound classes in the Yangtze River Estuary and the adjacent inner shelf. In surface sediments, the δ¹³C (−28.6 ± 0.6 ‰ in lipids;−21.8 ± 0.5 ‰ in THAAs) and Δ¹⁴C (−598 ± 41 ‰ in lipids;−143 ± 47 ‰ in THAAs) values of lipids and THAAs from the mobile-muds are lower than those from the offshore areas (δ¹³C: −27.9 ± 0.4 ‰ in lipids;−20.9 ± 0.8 ‰ in THAAs;Δ¹⁴C: −559 ± 20 ‰ in lipids;−64 ± 7 ‰ in THAAs), indicating replenishment of marine source may be the primary factor contributing to the rejuvenation of lipids and THAAs during seaward transport. In contrast, both HAs and acid-base insoluble OM have higher Δ¹⁴C values in mobile muds (−298 ± 28 ‰ and −322 ± 21 ‰, respectively) than those in offshore areas (−443 ± 14 ‰ and −533 ± 30 ‰, respectively), suggesting significant aging even for the refractory OM during transport processes. The three end-member model of organic compound classes shows that lipids and THAAs in mobile-muds have higher marine source than offshore areas, while HAs show opposite change. These results indicate organic compound classes undergo different transport and degradation mechanisms during seaward transport, then affecting the contributions of marine and terrestrial sources to marine sediments. The different correlations between Δ¹⁴C values of labile (THAAs) and refractory (HAs and a

Osteoblasts are essential in the maintenance of human bone homeostasis.1 The abnormal formation and impaired differentiation ability of osteoblasts are pivotal factors leading to bone-related diseases,suggesting that an indepth study of osteoblasts can provide novel treatment strategies for these diseases.2 Human primary osteoblasts are precious experimental models in bone-related research.3 However,the isolation and culture of human primary osteoblasts still have some difficulties and ***,we refined a method to isolate and culture human primary osteoblasts by taking cancellous bone through a bone tissue sampler and pre-digesting it with pancreatin,which makes the process easier,cheaper,and more ***,we compared the effects of the subtle changes in isolation and culture methods on the phenotype of human primary osteoblasts and examined the differences in morphology,proliferation,and differentiation between micro-explants cultured osteoblasts(MECOBs)and explants cultured osteoblasts(EC-OBs).
