产业兴旺是乡村振兴战略中的首要任务,也是解决我国农村经济社会问题的关键。湘西州是湖南省政府脱贫攻坚的重点地区,相对单一的产业结构表面上拉动了全州经济的平稳增长,但也带来了原有财政投入折旧加速、经济增长受限、居民幸福感降低等一系列问题,尤其是以牺牲工、矿产业为代价兴起的旅游服务业,加剧了当地的结构性失业,若矛盾没有解决,未来全州经济将有可能因单一产业波动受到较大影响。全州应充分考虑各县、市特有的自然资源、气候条件,借助"乡村振兴"这一政策红利,通过产业融合联动,因地制宜地布局三大产业,在平稳的经济增长进程中,务必寻找新的经济增长点,吸引青年返乡就业创业,构建美丽大湘西。

云计算环境下的任务调度问题是当前研究的热点问题,而遗传算法(Genetic Algorithm,GA)是解决任务调度问题的重要智能算法之一。文章针对基于吞噬机制改进遗传算法(Phagocytosis Improved Genetic Algorithm,PIGA)在云任务数量较大的情况下,应用吞噬机制解决任务调度问题时易出现大量云任务集中于一台或者几台虚拟机,使得算法收敛于局部最优解的问题展开研究,并以最短云任务执行时间为目标,在IGA(Improved Genetic Algorithm)调度的基础上,改进吞噬机制,将"吞噬细胞"、"普通细胞"、"病原体细胞"的概念引入到该算法中,提出增强型吞噬遗传算法(Enhanced Phagocytosis Genetic Algorithm,EPGA),探寻更快的云任务执行时间。仿真实验表明,与GA、IGA、PIGA相比,所提算法明显改善了云任务的完成时间,并且在云任务数量较大的情况下,EPGA较PIGA更能探寻到最优解。

The Salmonella pathogenicity islands(SPIs) play crucial roles in the progression of Salmonella infection. In this study, we constructed an improved λ Red homologous recombination system to prepare single and triple deletion mutants of 3 prominent SPIs(SPI-1, 2, and 3), aiming at the impact of deletion on morphology, carbon source metabolism, adhesion and invasion capacity, in vivo colonization, and immune efficacy in chicks. Our examination revealed that the surface of the single deletion mutants(SM6ΔSPI1, ΔSPI2, and ΔSPI3) exhibited a more rugged texture and appeared to be enveloped in a layer of transparent colloid, whereas the morphology of the triple deletion mutant(SM6ΔSPI1&2&3) remained unaltered when compared to the parent strain. The carbon metabolic spectrum of the SPI mutants underwent profound alterations, with a notable and statistically significant modification observed in 30 out of 95 carbon sources, primarily carbohydrates(17 out of 30). furthermore, the adhesion capacity of the 4 mutants to Caco-2 cells was significantly reduced when compared to that of the parent strain. Moreover,the invasion capacity of mutants SM6ΔSPI1 and SM6ΔSPI1&2&3 exhibited a substantial decrease, while it was enhanced to varying degrees for SM6ΔSPI3 and SM6ΔSPI2. Importantly, none of the 4 mutants induced any clinical symptoms in the chicks. However, they did transiently colonize the spleen and liver. Notably, the SM6ΔSPI1&2&3mutant was rapidly cleared from both the spleen and liver within 8 days post-infection and no notable pathological changes were observed in the organs. Additionally, when challenged, the mutants immunized groups displayed a significant increase in antibody levels and alterations in the CD3+CD4+ and CD3+CD8+ subpopulations, and the levels of IL-4 and IFN-γ cytokines in the SM6ΔSPI1&2&3 immunized chicken serum surpassed those of other *** summary, the successful construction of the 4 SPI mutants lays the groundwork for further exploration into the p
