基于高效能大任务和多任务计算需求以及芯片技术的高速发展,多核处理器进入片上众核处理器时代,但如何将这种硬件能力转变成计算性能的提升,充分利用MPSo C的并行计算能力是该领域亟待解决的问题.文中研究设计了面向片上众核处理器的物理核到虚拟核分配算法(VPD),该算法通过识别任务执行时的阶段状态特征,动态重组物理核并配置成与任务计算需求相适应的虚拟核,在满足任务的计算资源需求的条件下,实现虚拟核最优分配.最后通过实验将VPD算法与不同的多核/众核处理器环境下的主流调度算法进行比较,结果表明:该算法可适用于多种环境,且效能比其他同类算法平均高5%~10%.

区域政策对工会维权实效的影响是研究劳动关系的重要内容,然而政策环境不断变化,新生代农民工的教育水平、社会融合能力等个人特征与上一代农民工不再类同,相关研究有待扩展。文章借助博弈理论和定序probit模型证实信号不充足的情况下,采取适当的区域激励政策只能缓解紧张的劳资关系,并不一定能达到改进社会福利的目的;工资协商、企业工作环境、社会服务对新生代农民工工会参与满意度影响显著;教育水平、社会融合水平、法律知识等个人特征变量对工会维权效果的影响存在地区差异。因此,区域政策对新生代农民工工会维权实效发挥积极影响,需要信息充足及诸因素有效配合等条件。

Objective:To investigate the genetic polymorphisms of the glutathione S-transferase M1,T1,and P1 genes(GSTM1,T1,and P1)and to assess the oxidative damage in infertile men with varicoceles from northwestern *** and materials:Sixty-five infertile men with varicoceles and 30 controls were included in the *** polymerase chain reaction(PCR)and polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP)analysis were used to identify the *** DNA damage was assessed by terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end-labeling(TUNEL).The levels of 8—hydroxy-2’-deoxyguanosine(8—OH-dG)were measured by high-performance liquid chromatography with electrochemical detection(HPLC—ECD).The activity of malondialdehyde(MDA)and nitric oxide(NO)and the total antioxidant capacity(TAC)were detected by spectroscopic analysis,and sperm characteristics were measured using computer-assisted semen analysis(CASA).Results:The frequencies of the GSTM1,T1 and P1 genotypes were not significantly different between the control and patient groups(P>0.05).The percentage of TUNEL-positive sperm and the levels of 8-OH-dG,MDA,and NO were higher but the sperm concentration and motility and the TAC were lower in thepatients with the GSTM1,T1 and GSTM1/T1 null genotypes than those in the patients with the GSTM1,T1 and GSTM1/T1 present genotypes(P0.05).Conclusions:Our results suggest that the GSTMl and T1 null genotypes may predispose sperm to increased oxidative damage in infertile men with varicoceles;however,GSTP1allelic variation was not significantly different between the patient and control groups in this study.

We present two E-W trending wide-angle seismic profiles(OBS2013-ZN,OBS2014-ZN),which cross the boundary(Zhongnan fault)between the east sub-basin and the southwest sub-basin of the South China Sea(SCS).We processed the data and used 2D ray-tracing to determine the oceanic crust thickness,velocity structures and Moho depth variations related to *** simulated velocity models show that the sea basin of the SCS has a typical oceanic crust covered by a 1-2 km thick sediment layer with a velocity of 2-3.5 km/*** crust has a thickness of 5-8 km,of which the oceanic layer 2 is 1.8-3 km thick,with velocity increasing downward from 4.3 km/s to 6.4 km/s,and the oceanic layer 3 is 3-5 km thick,with velocity increasing downward from 6.4 km/s-7.0 km/*** sea basin Moho depth is approximately 6-7km below *** Moho discontinuity has an obvious upheaval zone with a low velocity of7.6 km/s,which corresponds to the low velocity zone in oceanic layer *** constructed a NW-SE-trending fracture zone(40-60 km wide)rather than a major"Zhongnan fault"oriented N-Sby connecting the upheaval portions of the Moho in the two *** to the stress direction variations and the seafloor spreading stepwise propagation models of the SCS,We suggest that the faults or fracture zones in the oceanic basin of the SCS were the transform faultfor the break-up of the Macclesfield-Reed Bankand formed in section with varied trending directions controlled by varied stress fields during the multi-episode evolution of the SCS.

采用固相反应法制备0.7BiFeO3-0.3BaTiO3+0.35%(摩尔分数，下同)MnO2+x%LiF(BF-BT-MN-xLF)压电陶瓷。采用XRD,SEM,铁电测试系统和精密阻抗分析仪测试陶瓷的物相组成、显微结构和铁电、压电性能。结果表明：LiF掺杂加强晶格畸变，促进烧结和晶粒生长，改善压电性能的温度稳定性。Li+和F-不等价取代A/B位产生的复合缺陷偶极子，转向速度滞后于外加电场的变化，导致电滞回线呈现夹持现象。同时，对BF-BT-MN-xLF陶瓷的退极化行为以及居里温度变化的研究表明，LiF掺杂显著提高陶瓷的居里温度Tc和退极化温度Td,Tc和Td分别由500℃和410℃(x=0)升高到550℃和505℃(x=0.50)。当LiF掺杂量为0.50%时，在860～1020℃温度范围内烧结的陶瓷始终保持较高的压电系数，d33=176～202 pC/N。x=0.50的陶瓷样品在960℃烧结表现出最佳的压电性能：d33=202 pC/N,kp=34%,Tc≈550℃,Td1≈505℃。
