NUCLEAR-INDUCED PARTICLE SUPPRESSION AT LARGE xF AT RHIC

迷走神经变异在甲状腺结节射频消融中的临床意义

The 19th International Conference on Ultra-Relativistic Nucleus-Nucleus Collisions

作者： j.h. lee for the BRAhMS Collaboration Department of Physics Brookhaven National Laboratory Upton NY 11973 U.S.A.

＜正＞The available kinematic phase-space at large Feynman-x （xF） demands the probability of particle production to be constrained. In the nuclear medium, the effect is expected to be enhanced by multiple interactions given to the projectile parton. This effect, referred to as the Sudakov suppression is exhibited to be scaled with xF. To understand the dynamic nature of nuclear collisions, it is important to distinguish such kinematically dominated effects from dynamically driven processes, such as parton energy loss in the hot nuclear medium and gluon saturation in the initial state. The BRAhMS experiment have measured centrality dependent particle productions in wide kinematic ranges （0.3＜pT＜2.5-4 GeV7c,0＜xF＜0.4-0.9） in d+Au, Au+Au, and Cu+Cu at

Carbide nucleation, growth and trapping behavior in directionally solidified MAR-M247 LC alloy and the corresponding mechanism have been investigated. Carbide forming element enrichment controls the carbide nucleation and the carbide growth behavior. If the carbide forming element enrichment and the nucleation sites are suitable, carbide nucleation can occur both above and below the liquids temperature. heterogeneous carbide nucleation is the preferred nucleation mechanism at low carbide forming element enrichment. Carbide growth occurs mainly at inter-secondary gamma dendrite arm area and lower part of the mushy zone. The carbides are subsequently trapped at these positions after growing to a certain size. Some carbides are only partially trapped by the solid-liquid interface and the carbide growth accelerates after being partially trapped. A critical growth rate exists between 2 multiplied by 10** minus **6 m/s and 5 multiplied by 10** minus **6 m/s. The carbide volume fraction decreases in the directionally solidified part at slow growth rate which is caused by the lack of suitable growth site and the low trapping ability of the solid-liquid interface.

Cylinder-to-bed heat transfer in agitated fluidized beds was studied experimentally. In the experiments, the aluminum particles were used as bed material, the diameter of those ranged from 0.5 mm to 2 mm. The effects of gas velocity, particles size, and agitator rotary speed on heat transfer were studied. From the experimental results, we have come to the following conclusion: (1) there are optimal ranges for airflow velocity and rotary speed to get optimal heat transfer coefficient; (2) the cylinder-to-bed heat transfer is greatly affected by gas velocity, rotary speed and particles sizes, and the effect of rotary speed on heat transfer is similar to that of gas velocity; (3) higher heat transfer coefficient is obtained with smaller particles.

Most of the assessment equations for Ct which is a wellknown fracture parameter characterizing high temperature crack growth rates, have limited applicability to constant load conditions after sudden loading. however, crack growth due to creep can also occur under load varying conditions when load rising time is so long that accumulated creep deformation near the crack tip is not *** this paper, the estimation equation of the Ctparameter which can be applied to the case of slow load rising, i.e., (Ct)r, is explained. And the correlation between (Ct)r at the end of the load increasing period and Ct at the beginning of the succeeding load hold period is discussed. Finite element analyses of several cases with various loading conditions were performed and results were presented to show the effectiveness of the proposed Ct estimation scheme. The general applicability of the equation is also discussed.

目的确定乙型肝炎病毒（hBV）DNA水平与经动脉化疗栓塞治疗（TACE）的肝细胞癌病人生存期之间的关系。材料与方法本研究经机构审查委员会批准,并免除病人知情同意书。连续纳入2005年1月—2007年3月间的183例hBV源性肝细胞癌病人。入组病人均行TACE治疗,但未接受抗病毒治疗。所有病人均在行TACE治疗前检测血清hBV DNA水平,计算其从入组当天至死亡时的总体生存期。借助于独立的影像学评估,应用改良实体肿瘤反应评价标准评估肿瘤进展。结果总体生存期的中位数为19个月（95%CI:13.7;4.3）,疾病进展时间的中位数为4个月（95%CI:3.03;.97）。多因素分析显示,TACE术前的hBV DNA血浆水平高（>2000IU/L）是降低总体生存期[P=0.021;风险比（hR）,1.725]、癌症进展-相关高死亡率（P=0.014;hR,1.936）及癌症进展所致肝衰竭相关死亡率（P=0.005,hR,3.908）的独立危险因素。TACE术前hBV DNA水平对非癌症进展所致肝衰竭相关死亡率无显著影响。结论 TACE术前的hBV DNA血浆水平高与TACE术后较差的总体生存期和肝细胞癌的快速进展相关,病人死于癌症的快速进展而非肝炎的恶化。

Ab initio calculations with the self-consistent full-potential linearized augmented-plane-wave method （FLAPW）, under generalized gradient approximation, have been carried out to describe the electronic and magnetic properties of 3d transition metal dimers. It predicted the antiferromagneticity of Cr2 and ferromagneticity of other species. The Mn2 dimer was shown to be ferromagnetic coupling with a local magnetic moment of 5μB. retaining the value of its free atom state. The V2 and Ni2 exhibited low spin-polarization with local magnetic moment of only 1μB per atom. On the other hand, Fe2 and Co2 were highly spin-polarized with local magnetic moments of 3 and 2μB.
