目前针对节点失效的虚拟网络恢复问题研究都是针对单域物理网络,而现实网络都是多域分布的。因此,提出了针对多域网络中的单节点失效(SNFMDN)问题的虚拟网络恢复策略。以最大化恢复率和最小化恢复成本为目标,建立了SNFMDN问题的整数规划模型;为快速求解该问题,提出了2种基于带宽消耗的虚拟网络恢复算法。实验结果表明,所提出的恢复策略可以有效地恢复受影响的虚拟网络,且恢复成本也相对较低。

ObjectiveTo explore the regulatory effect of Pien Tze Huang (PZH) on targeting partner of NOB1 (PNO1) and it’s down-stream mediators in colorectal cancer (CRC) *** polymerase chain reaction was performed to determine mRNA levels of PNO1, TP53, and CDKN1A. Western blotting was performed to determine protein levels of PNO1, p53, and p21. HCT-8 cells were transduced with a lentivirus over-expressing PNO1. Colony formation assay was used to detect cell survival in PNO1 overexpression of HCT-8 cells after PZH treatment. Cell-cycle distribution, cell viability and cell apoptosis were performed to identify the effect of PNO1 overexpression on cell proliferation and apoptosis of HCT-8 cells after PZH treatment. Xenograft BALB/c nude mice bearing HCT116 cells transduced with sh-PNO1 or sh-Ctrl lentivirus were evaluated. Western blot assay was performed to detect PNO1, p53, p21 and PCNA expression in tumor sections. Terminal deoxynucleotidyl transferase dUTP nick end labling (TUNEL) assay was used to determine the apoptotic cells in *** treatment decreased cell viability, down-regulated PNO1 expression, and up-regulated p53 and p21 expressions in HCT-8 cells (P<0.05). PNO1 overexpression attenuated the effects of PZH treatment, including the expression of p53 and p21, cell growth, cell viability, cell cycle arrest and cell apoptosis in vitro (P<0.05). PNO1 knockdown eliminated the effects of PZH treatment on tumor growth, inhibiting cell proliferation inhibition and apoptosis induction in vivo (P<0.05). Similarly, PNO1 knockdown attenuated the effects of PZH treatment on the down-regulation of PNO1 and up-regulation of p53 and p21 in vivo (P<0.05).ConclusionThe mechanism by which PZH induces its CRC anti-proliferative effect is at least in part by regulating the expression of PNO1 and its downstream targets p53 and p21.

设备设施故障是公共交通系统运营安全事故发生的主要原因,为更好地度量和增强系统的安全韧性,提出融合复杂网络(CN)与功能共振分析方法(FRAM)的CN-FRAM运营安全韧性度量模型,并将系统韧性定义为扰动下系统性能损失与性能基线之比。首先,根据设备设施系统构成和节点功能,建立CN;其次,将FRAM模型嵌入到CN中,以扩展节点和连接,构建CN-FRAM模型;然后,基于CN-FRAM韧性度量模型分析系统组件之间功能变化的聚合,并在量化系统韧性时综合考虑网络整体效益和组件之间的耦合程度;最后,以南京市地铁信号系统为例,验证方法的可行性和有效性。结果表明:该模型可以量化系统破坏-恢复全过程的韧性,计算故障对系统的影响程度,并以韧性值最大化为目标,展现不同修复策略下的韧性表现,从而为确定最佳恢复顺序提供依据。对比现有方法,该方法所确定的最优恢复策略能显著减少系统因故障造成的整体性能损失,从而提高系统的韧性。

分数分班是指以学生的考试分数作为学校分班依据的教学管理机制。分数分班在大规模培养人才的同时也存在一些问题:在个体发展方面,存在学生主体性被忽视、“贴标签”及同伴效应差异化的问题;在教育教学方面,存在知识教育僵化、班级工具化和利益化及教育不公平循环的问题。基于因材施教理念,学校及教育行政部门应采取相应措施改善分数分班的教育现状,包括重视学生个体差异、优化教师配置、完善分班教育规则及改进考试评价机制等,以更好地促进学生全面发展。
