Advances in Manufacturing 2013年第3期1卷 218-225页

The integration of nanomaterials such as carbon nanotubes （CNTs） into microsystems is highly desirable, in order to make use of the unique nanomaterial properties in real devices. However, the CNTtomicrosystem integration is challenging to implement in a manufacturable, cost effective industrial process. This paper presents our work towards a process for making complete, integrated CMOS / MeMS systems with integrated CNT. We demonstrate the feasibility of the process, using roomtemperature process ing, lowcost equipment and consumables, and electrical control with automation possibilities. CNTs are directly integrated at the desired positions in the Si microsystem, forming closed Si / CNT / Si circuits. We explore different designs with the aim to obtain uniform and welldefined CNT synthesis conditions, and show that simplified designs can perform comparably to more complex ones. The Si / CNT / Si circuits obtained can show rectifying （Schottky like） or nearohmic behavior. Gas sensing possibilities are demonstrated, indicating the possibility of monitoring aging/ fermenting of food. Functionalization of CNTs is demon strated, using thermal evaporation of Sn and Pd, opening for selective and sensitive sensors for various gases and ana lytes. Detailed microscopic characterization of the obtained CNTs are presented.

坦桑尼亚Umba谷的电气石，随光通过电气石的路径长度的增加，其颜色由绿变为红。这种颜色变化称为“Usambara”效应，与以前描述的任何颜色变化效应是不同的。采用比色法对这种电气石进行分析、分析结果表明，Usambara效应是一种复杂现象，它包括光路径长度不同而造成的变色效应和不同光源下观察到的变色故应（变石效应）

世界核心医学期刊文摘（儿科学分册） 2006年第A10期2卷 13-14页

作者： halvorsen T. Skadberg B.T. eide G.e. 李开 Department of Pediatrics Haukeland University Hospital N- 5021BergenNorway

Aims: To assess whether lung function in late childhood had improved in subjects born extremely prematurely in the early 1990s compared to the early 1980s, and whether neonatal factors in the respective periods had different impact on long- term pulmonary outcome. Design: Population- based, controlled cohort study. Lung function was determined in 81 of 86 (94% ) eligible subjects born with gestational age ≤ 28 weeks or birthweight ≤ 1000 g in Western Norway in 1982- 85 (n = 46) and 1991- 92 (n = 35), and in 81 matched control subjects born at term. Results: The incidence of bronchopulmonary dysplasia was similar in the two periods. At follow- up, airway obstruction, hyper- responsiveness and pulmonary hyperinflation were similarly increased in both preterm cohorts compared to matched controls. Furthermore, current lung function was similarly related to neonatal respiratory disease in both birth- cohorts: FeV1 was reduced with respectively 18.6% and 18.7% of predicted in preterms dependent on supplemental oxygen at 36 weeks postmenstrual age. Lack of antenatal treatment with corticosteroids and prolonged neonatal oxygen treatment predicted similar significant airway obstruction in the two birth- cohorts Conclusion: Preterms born in different eras of neonatology had similar long- term decreases in lung function. Long periods of oxygen supplementation are still required to salvage immature infants, and airway obstruction may still be a common longterm outcome.

使用一种新方法一多余度分析(RDA),检查了是否挪威西部奈于斯特流域酸化的化学复原在大型底栖动物群落结构中产生了可测的复原。RDA结果与基于使用高度专门化和区域化界定的生物酸度指数测得的变化的复原测量值作了比较。我们发现,在1989～1998年期间,奈于斯特流域生物复原即开始出现。复原是在奈于斯特河上游及其各支流发生的。多变量方法已证明是酸度指数方法的一种补充,将两者结合使用能够得到大量的生物信息。RDA方法是一种保守的方法,即不会过高地估计生物复原,而且不像酸度指数。从地理上来说不会受到约束。我们还发现,一些季节性气候因素强烈地影响着底栖生物群落,可能引起对生物复原过程检测的混淆。

A first search for the Ξ_(bc)^(+)J/ψΞ_(c)^(+) decay is performed by the LHCb experiment with a data sample of proton-proton collisions, corresponding to an integrated luminosity of 9 fb−1 recorded at centre-of-mass energies of 7, 8, and 13 TeV. Two peaking structures are seen with a local (global) significance of 4.3(2.8) and 4.1(2.4) standard deviations at masses of 6571 and 6694 MeV/c2, respectively. Upper limits are set on the Ξ+bc baryon production cross-section times the branching fraction relative to that of the B+c→J/ψD+s decay at centre-of-mass energies of 8 and 13 TeV, in the Ξ+bc and in the B+c rapidity and transverse-momentum ranges from 2.0 to 4.5 and 0 to 20GeV/c, respectively. Upper limits are presented as a function of the Ξ+bc mass and lifetime.
