以N-丁基二乙醇胺(nbdeaH)为配体,通过辅助自组装反应和溶剂热法合成两组异金属多核簇合物。其中[MM’(μ-OH)(nbdea)(CHCO)]·MeCN(M=Ga,M’=Dy(2),M=Fe,M’=Y(3))与己发表的3d-4f异金属簇合物[FeDy(μ-OH)(nbdea)(CHCO)]·MeCN(1)同构,而[MM’(μ-OH)(nbdea)(m-CHCHCO)]·nMeCN(M=Ga,M’=Dy,n=4(5),M=Fe,M’=Y,n=1(6))与己发表的3d-4f异金属簇合物[FeDy(μ-OH)(nbdea)(m-CHCHCO)]·MeCN(4)同构。磁性测试表明,在化合物{GaDy}(2)与{GaDy}(5)中,Dy-Dy之间存在反铁磁耦合相互作用,而在化合物{FeY}(3)与{FeY}(6)中,Fe-Fe之间同样也存在反铁磁相互作用。由此可推测,在己发表的化合物{FeDy}(1)与{FeDy}(4)中,Fe-Dy之间应存在铁磁耦合相互作用。簇合物{GaDy}(2)和{GaDy}(5)表现出单分子磁体行为,其中(GaDy)(2)的有效能垒(U)与己知的同构簇合物{FeDy}(1)十分接近。这也是首次在Ga-Dy异金属簇合物中发现单分子磁体的弛豫现象。

Accurately approximating higher order derivatives is an inherently difficult problem. It is shown that a random variable shape parameter strategy can improve the accuracy of approximating higher order derivatives with Radial Basis Function methods. The method is used to solve fourth order boundary value problems. The use and location of ghost points are examined in order to enforce the extra boundary conditions that are necessary to make a fourth-order problem well posed. The use of ghost points versus solving an overdetermined linear system via least squares is studied. For a general fourth-order boundary value problem, the recommended approach is to either use one of two novel sets of ghost centers introduced here or else to use a least squares approach. When using either ghost centers or least squares, the random variable shape parameter strategy results in significantly better accuracy than when a constant shape parameter is used.

随着单细胞检测技术的迅速发展和成熟,单细胞生物学和病理学已成为了解疾病的新兴学科。然而,解决临床医生提出的关于如何将单细胞检测应用于临床实践、将单细胞系统生物学的信号转化为明确的临床表型、并预测患者对治疗反应的问题至关重要。本文提出了一个称为“临床人工智能单细胞”(clinical artificial intelligent single-cell,caiSC)的新系统,具有临床单细胞信息学的动态生成、人工智能分析、分子多模态参考模块储存、临床信息输入输出,以及基于人工智能计算程序化的能力。该系统在单细胞水平上为临床诊断、监测和疾病预测提供可靠且快捷的信息。临床人工智能单细胞是将单细胞检测转化为临床应用、助力临床医生决策、改善医疗服务质量的重要里程碑。鉴于与临床人工智能单细胞相关生物技术的快速发展,越来越多的证据支持“临床人工智能单细胞假说”实现的可能性。因此,我们呼吁广大科学家和临床医生加大对临床人工智能单细胞的关注和研究,相信临床人工智能单细胞将为临床分子医学的未来带来曙光。

Subsidence as a consequence of mining activity has been an onerous problem associated with mineral extraction in Britain. Mining law as it relates to subsidence has developed over several centuries. This paper will outline the legal implications for mineral subsidence and compensation, considering both common law and statute. Particular reference is made to the extraction of coal, salt in brine, protection of public utilities, working facilities orders, ironstone and ancient mining rights.
