Excited states of ^(206)Rn have been examined via the 197 Au(^(14)N,5n)^(206)Rn fusion reaction at a beam energy of 78 MeV.A number of transitions and levels are identified by the γ-γ coincidence measurement,further enriching the level scheme of ^(206)*** fullconfiguration shell model and nucleon-pair approximation(NPA)were utilized to investigate the single-particle configurations and seniority structures in ^(206)*** results of these two calculations suggest that 2_(1)^(+) and 4_(1)^(+) states exhibit only a 50%component of a seniority-two state associated with a broken neutron *** collectivity of these two states primarily arises from configuration mixing due to residual proton-neutron ***,6_(1)^(+) and 8_(1)^(+) states are predominantly characterized by a seniority-two state marked by a broken proton pair.

Objective To study the effect of vasocation intestinal peptide （VIP） on immune privilege of the rat testis. Methods The UU infected SD rats and Leydig cells were intervened by VIP, the secretion of TGF-β and the expression of FasL in rat Leydig cells were compared between VIP-intervened group and control group to test the effect of VIP on immune privilege of the rat testis in vitro and in vivo. Results In vitro, the secretion of TGF-β in Leydig cells could be increased by low dosage of VIP while inhibitited by high dosage of VIP; expression of FasL mRNA in Leydig cells could be decreased by VIP In vivo, increased expression of TGF-β mRNA and decreased FasL mRNA were observed in VIP group in 2-3 weeks after infected by UU. In addition, the apoptosis of Jurkat cells mediated by Leydig cells could be prevented by VIP Conclusion When Leydig cells or testis infected by UU, VIP could regulate the immune function of rat Leydig cells and participate in the regulation of immune privilege of testis through the regulation of TGF-β secretion and FasL expression pattern of Leydig cells.

蚊虫传播的黄病毒造成的传染病是人类健康的重要威胁,有效的早期精确诊断对预防与控制黄病毒感染并及时有效开展病患救治至关重要。然而由于黄病毒在血液中核酸可检测窗口短,核酸检测手段难以发挥优势,必须要通过血清学的诊断与病毒分离予以佐证,而血清学检测也要面对黄病毒之间存在的交叉反应问题。本文介绍了基于黄病毒非结构蛋白1(NS1)建立的检测手段。NS1蛋白在病人血清中含量很高是良好早期诊断靶标,基于NS1蛋白的黄病毒血清学诊断的检测窗口较长、灵敏度高、特异性强,具有独特的优势。尤其是2016年寨卡病毒暴发以来基于NS1的检测技术在灵敏度与特异性上得到快速与多元的发展,为黄病毒的精确检测带开启了新的局面。

多核处理器的最后一级缓存(Last Level Cache,LLC)采用共享机制,当多个程序并行随机访问LLC时,可能引起访存冲突,进而导致系统整体性能的大幅下降.已有研究者试图通过引入缓存划分,合理安排不同程序对LLC的访问时机,解决访存冲突问题.然而,现有的缓存划分方法主要采用启发式算法,即通过不断“试错”寻找缓存划分最优方案,寻找过程具有不确定性.这种不确定性可能导致划分开销过大甚至出现无法收敛的问题.为此,我们提出了一种基于机器学习的跨平台缓存划分方法MLPart.该方法借助少量运行参数,利用决策树和序列到序列模型预测剩余各个划分方案的性能,直接找到最优的划分方案,从而保证划分开销相对稳定且有效避免了无法收敛的情况.此外,实验表明如果计算平台之间存在着微小配置差异,即使运行相同程序所产生的运行参数也存在较大差异,因此单一模型通常没有足够的泛化能力适应不同的平台.为解决该问题,我们分别利用迁移学习技术和微调技术优化决策树和序列到序列模型,使其能以较低的计算开销完成不同平台的模型快速迁移部署.我们以当前主流的Intel至强(Xeon)处理器平台展开实验,实验结果表明MLPart能够通过少量划分步骤找到性能最佳的缓存划分方案;并且,与采用启发式缓存划分方法KPart,采用基于贝叶斯优化的缓存划分方法CLITE以及采用机器学习的缓存划分方法C&A相比,MLPart对工作集的性能提升更高且更为稳定.

To the Editor： In former times, traditional Chinese medicine （TCM） individualized its treatment protocol or clinicalpractice without considering the principles of modem medicine. The standard methodology of random selection, blinding and placebo control, followed by statistical analysis was generally overlooked. This had a negative effect on the development of TCM. Recently, the volume of applied research in Chinese medicine is growing rapidly and the quality is improving.^1 There is good evidence supporting the use of some Chinese patent medicine treatments.^2-4 Further, there is a more open attitude to Chinese medicine among conventional health professionals, partly explained by the rise of evidence-based medicine （EBM）.
