论赞助人对西南联大文学翻译活动的操控

西南联大文学翻译活动始终处在赞助人体系的操控之下。间接赞助人在相互斗争中达成妥协,为西南联大文学翻译活动创造了相对独立、宽松和自由的社会文化氛围,从而使文学翻译独立于主流战争文学之外,实现了翻译作品多样化与纯文学化。直接赞助人白英对翻译活动的影响更为具体。白英的个人喜好决定了翻译文集的选材,白英个人的翻译思想被译者们奉为翻译圭臬,在翻译文集中处处得以体现。     

Embryonic stem cells and their genetic modification Nobel prize in Physiology or Medicine 2007

The derivation of embryonic stem cells from mice and the development of techniques that allow for targeted manipulation of its genome have allowed for the generation of mice with desired mutations. This is what led to the announcement in Stockholm in 2007 — “The Nobel Assembly at Karolinska Institute today decided to award the Nobel Prize in Physiology or Medicine for 2007 jointly to Mario R Capecchi, Martin J Evans and Oliver Smithies for their discoveries of Principles for introducing specific gene modifications in mice by the use of embryonic stem cells”. Martin J Evans was recognised for his derivation and establishment of mouse embryonic stem cells while Mario Capecchi and Oliver Smithies were honoured for techniques that allowed site-specific modification of sequences within the genome of these cells. Such cells were then used to generate animals that had their genome altered specifically and at desired locations. For this valuable body of work, all three shared the prize equally. To date, almost half of the genes in the mouse genome have been modified using their techniques. This has led to a better understanding of mammalian physiology, development and diseases. Mitradas M. Panicker is on the faculty of the National Centre for Biological Sciences, Bangalore, India. His research interests include stem cells, serotonin and its receptors and neurobiology.     

植物性细胞、受精及胚胎发生离体操作系统的创建与实验生物学研究

我们从事植物生殖的实验研究已有近30年历史。20世纪80年代中后期，我们认识到实验胚胎学的发展趋势是由器官、组织操作向细胞、原生质体操作的水平提升，同时加强研究的多学科性与综合性，从而提出了植物实验生殖生物学与生殖细胞工程的研究思路。

新型一维碳基纳米材料的自旋热电效应

基于第一性原理的方法,从原子层面上研究了锯齿型石墨烯纳米条带与碳链以及石墨烯纳米片组成的一维碳基纳米材料的自旋热电性能.研究发现在费米面处自旋向下的传输函数压抑至零,而自旋向上的传输函数大约为0.25,具有理想的半金属性质.另外声子部分热导明显小于对应的电子部分热导.同时低温区域(80 K附近)自旋Seebeck系数明显得到加强,导致了电荷和自旋热电品质因子接近40.并且在室温区域,自旋热电品质因子明显大于对应的电荷热电品质因子.     

丰中子奇A核37-47P自旋和宇称的相对论平均场模型研究

用相对论平均场模型结合NL3、TM2和NL-SH参数对P的奇A核同位素的2s1/2和1d3/2单质子能级变化趋势以及自旋和宇称进行了理论计算.发现丰中子同位素37-47P,尤其是47P中可能存在2s1/2和1d3/2单质子能级反转.对于37P和39P,TM2和NL-SH参数给出的自旋和宇称是（3/2）＋,NL3给出的是（1/2）＋;对于41-47P,NL3、TM2和NL-SH给出的自旋和宇称都是（3/2）＋.自旋和宇称的结果只有部分和NUBASE2012中的估计值是一致的.     

自旋场效应晶体管中极化输运特性研究

自旋极化电流从铁磁金属注入到半导体的主要障碍是铁磁体和半导体电导率的不匹配。但最近研究结果表明可以通过运用适当的方法来克服这个困难。我们基于自旋场效应晶体管的模型及Landauer-Buttiker公式,求得电子通过半导体异质结的电导,得出了自旋电子器件中极化电荷的输运特性。     

Biomechanics of increased spin velocity of flying discs during forehand throws by skilled and unskilled throwers

We aimed to assess the relationship between throwing distance and kinematic release parameters of the flying disc in unskilled throwers, and to assess the relationship between kinetic variables acting on flying discs and the change in spin velocity during long forehand throws by skilled and unskilled throwers. Ten skilled and eleven unskilled throwers performed throws at maximum effort. Reflective marker positions on the disc and body were recorded with a 3D motion capture system during the throws to derive kinematic variables of a disc and kinetic variables acting on the disc. The analysis interval was from maximum external shoulder rotation to disc release. Significant correlations were observed between the throwing distance and spin velocity in skilled (r = 0.722, P < 0.05) and unskilled throwers (r = 0.794, P < 0.01), between the change in spin velocity and the angular impulse of moments of force, in unskilled throwers (r = 0.703, P < 0.05), and between the change in spin velocity and the angular impulse of torque among skilled throwers (r = 0.680, P < 0.01). Therefore, a strategy for increasing spin velocity in unskilled throwers could be used to generate a larger torque, similar to that observed in skilled throwers.
