为了解决当前加速器控制系统在数据管理方面所面临的海量数据安全存储和高效分析处理的问题,在现有的基础上引入了Hadoop大数据框架,并结合大数据其他相关组件,构建一个分布式数据仓库系统。文章详细阐述了数据仓库的搭建过程,包括软硬件架构以及将数据从现有数据库抽取、转换和加载到数据仓库的方案。特别是针对系统归档数据的存储和分析需求,根据实际应用场景设计一个基于HBase的存储解决方案。在系统部署完成后,进行了吞吐量测试,并与当前使用的传统数据库进行性能对比。测试结果显示,基于Hadoop的数据仓库系统在海量数据存储、高性能查询以及数据分析处理方面都表现出明显的优势。这一改进为加速器控制系统提供了更强大的数据管理和处理能力,有望为加速器在未来的发展提供更多可能性。

肿瘤化疗的多药耐药性(multi-drug resistance,MDR)是提高抗肿瘤治疗效果的主要挑战之一。如何克服肿瘤MDR的问题,已成为当前肿瘤治疗领域的重要研究方向。随着对肿瘤免疫微环境的深入理解,肿瘤免疫逃逸机制以及免疫治疗已经成为肿瘤免疫学研究的热点之一。由于较高的安全性、疗效的长效性以及广泛的适用性,免疫疗法在恶性肿瘤的治疗中引起了越来越多的关注。其中,靶向B7家族辅助治疗已经被应用于多种实体瘤的临床治疗。B7家族属于免疫球蛋白超家族,它们在肿瘤微环境内的肿瘤细胞和免疫细胞中表达,与肿瘤细胞的增殖和转移密切相关。B7家族分子在肿瘤耐药性的发展中起到了重要作用,因此,通过靶向B7家族分子进行的免疫疗法可能具有克服恶性肿瘤MDR的潜力,从而实现治疗效果的提升。本文就B7家族分子与肿瘤MDR的最新研究进展进行综述,为克服肿瘤MDR和肿瘤治疗提供有前景的方法。

Abstract： In order to gain a better performance and reduce the computational complexity of the filter design in the underwater acoustic single car rier system, a new Iterative Block DFE （IBDFE） is proposed, which operates iteratively on blocks of the received signal, and fully implements its filtering operations by Discrete Fourier Trans forms （DFTs）. Two design methods are consid ered for IBDFE： one is HDIBDFE, and the oth er is SDIBDFE. In this paper, the first one is a dopted. In this scheme,

通常情况下,汽车发动机标定在25℃恒温实验室进行,但夏季的实际用车环境温度在30~50℃。环境温度不同,使客户实际用车环境与整车研发阶段试验边界不匹配,从而导致客户在夏季用车油耗偏高。因此,在中冷后温度下对一款1.4 L排量涡轮增压... 详细信息

通常情况下,汽车发动机标定在25℃恒温实验室进行,但夏季的实际用车环境温度在30~50℃。环境温度不同,使客户实际用车环境与整车研发阶段试验边界不匹配,从而导致客户在夏季用车油耗偏高。因此,在中冷后温度下对一款1.4 L排量涡轮增压发动机进行了详细的台架点火角标定实验和实车油耗测试,对比分析了不同中冷后温度下的油耗差异。结果表明:中冷后温度越高,点火角越靠后,发动机万有油耗率越高,整车燃油经济性越差。
