目的探索一种常规术前CT检查评估胸膜受侵的简单、无创技术。材料与方法本项回顾性研究经机构审查委员会批准,并签署关于初次级随访CT检查的知情同意书。评估术前CT表现(169例疑有胸膜受侵的病人)和手术切除后的病理诊断。在CT影像上测量原发肿瘤与邻近结构交界面的长度(弧距)和肿瘤的最大直径,然后计算弧距与肿瘤最大直径的比值。采用受试者操作特征(ROC)曲线分析该比值。结果应用国际抗癌联合会TNM分期系统,根据弧距与肿瘤最大直径比值的中位数将胸膜侵犯分级如下:pl1为0.206(第1—第3个百分位数:0～0.486);pl2为0.638(第1—第3个百分位数:0.385～0.830);pl3为1.092(第1—第3个百分位数,1.045～1.214)(组间P0.9时,胸膜受侵的敏感度、特异度及ROC曲线下面积分别为89.7%、96.0%和0.976,较应用常规标准测量值的敏感度和特异度(诊断医师A和B:分别为46.7%和74.2%,91.3%和84.8%)有所提高。结论应用弧距与肿瘤最大直径比值诊断T3或T4期肺癌可达到比应用常规标准更高的性能等级。弧距与肿瘤最大直径比值的测量是一种评估胸膜受侵的简单无创技术。

Large grain niobium h.s th. potential of simplifying th. production sequence and consequently reducing th. cost of th. superconducting RF cavities for ILC. To investigate th. feasibility of fabrication and th. possibility to ach.eve h.gh.gradient by large grain cavities, two 1.3 Gh. cavities were made of Ch.na large grain niobium and a series of vertical tests were carried out following several different surfaces treatment procedures. Two cavities h.ve both.reach.d th. h.gh.gradient of more th.n 43 MV/m repeatedly and th. maximum accelerating field of 47.9 MV/m h.s been ach.eved by Ch.na large grain niobium. Th.s paper introduces th. features of th. fabrication and surface treatments on th. large grain cavities and presents th. preliminary results of th. research.

We describe a new active-set, cutting-plane Constraint Optimal Selection Tech.ique (COST) for solving general linear programming problems. We describe strategies to bound th. initial problem and simultaneously add multiple constraints. We give an interpretation of th. new COST’s selection rule, wh.ch.considers both.th. depth.of constraints as well as th.ir angles from th. objective function. We provide computational comparisons of th. COST with.existing linear programming algorith.s, including oth.r COSTs in th. literature, for some large-scale problems. Finally, we discuss conclusions and future research.

h. international h.ph. collaboration proposes to perform h.pernuclear spectroscopy with.stable h.avy ion beams and rare isotope beams at GSI and FAIR in order to study neutron and proton rich.h.pernuclei and to measure directly h.pernuclear magnetic moments for th. first time. Th. project is divided into four ph.ses. In th. first Ph.se 0 experiment,th. feasibility of precise h.pernuclear spectroscopy with.h.avy ion beams will be demonstrated by observing π-decay ch.nnels of 3Λh.4Λh.and 5Λh. with.6Li projectiles at 2 AGeV impinging on a 12C target. In th. later Ph.ses 1 th.ough.3,studies of proton and neutron rich.h.pernuclei,direct measurements of h.pernuclear magnetic moments and th. spectroscopy of h.pernuclei toward th. nucleon drip-lines are planned.

Planktonic foraminiferal δ18O record for core DGKS9603 from th. Okinawa Trough.sh.ws a series of climatic fluctuations and sudden cooling events in sh.rt time scale during 50 kaBP, wh.ch.appear to correlate closely toth. Younger Dryas and h.inrich.events h.-5 recorded in Ch.nese loess, th. South.Ch.na Sea, th. North.Atlantic cores and th. Greenland ice cores. Th.ee polarity reversal events, correlating to Goth.nburg, Mungo and Lasch.mp events, approximately correspond to h.inrich.events h., h. and h. respectively, wh.ch.could be a cause of global climate ch.nges. Th. δ18O curve of th. Okinawa Trough.is well associated with.th. grain size record of th. Lijiayuan loess profile in north.estern Ch.na and is somewh.t different from th. climate fluctuations documented in th. Greenland ice cores. Th.se correlation results indicate th.t regional factors play an important role in controlling th. climate ch.nges in th. East Asia, and th. East Asian Monsoon could be th. prominent regional controlling factor.
