In the low aspect ratio torus experiment （LATE） device, plasma current is initiated and ramped up to 20 kA solely by microwave power at the electron cyclotron （EC） range of frequency with a ramp of the external vertical field By for the radial equilibrium of plasma torus at larger currents. Measurements suggest that an energetic electron tail in the energy range of about 200 keV carries the current. The line averaged electron density is higher than the plasma cutoff density, suggesting that tail electrons might be driven by electron Bernstein waves modeconverted from the launched electromagnetic waves.

An anomalous phenomenon of wave energy deposition and its evolution were noticed in the beginning phases of lower hybrid wave injection in JT-60U experiments. It was found that the driven currents are always formed in the central region of the plasma column in the first several hundred milliseconds of the wave pulses, no matter what N|| spectrum of the waves is. Then the driven current profile will change to their normal situation gradually, which depends on N|| spectrum closely.

本文着眼于中世东亚同时存在的、称为“圣母”的山岳女神,用宏观的,并且是俯瞰式的视角来考察东亚世界可能拥有“共同”的宗教经验。“圣母”这一尊称在亚细亚广泛存在,笔者认为可能是由于宋代碧霞元君“圣母”尊称的影响,但不同的“圣母”信仰有相同的地方,也有不同的地方。例如日韩的“圣母”有共同的虚舟传说。另一方面,中韩的“圣母”都是山岳女性宗教者。本文通过考察指出日韩“圣母”信仰内容上的差异,源自日韩对道教信仰的不同接受,又由于日本山岳信仰中有“女人禁制”,所以不存在女性信教者,这对日本接受道教信仰有一定的障碍性的影响。

随着佛教的渗透,在唐代,特别是中唐前后“河伯”被龙神代替,民间的龙神祭祀开始出现在诗文作品中,但其祭祀被定位为“淫祀”的一种。白居易和韩愈在《黑潭龙》《题炭谷湫祠堂》中将龙神的淫祀问题与奸臣、天子权威问题相关联,从中能够看出中唐时期诗人们的危机感和问题意识。而从盛唐到中唐,“代表国家安宁的龙”的象征性的崩坍,在杜甫的《奉同郭给事汤东灵湫作》诗作中可以看到。中唐时期洞庭湖水域作为非祭祀对象的恶龙等妖物的栖息地,频繁地出现在士人们的诗文中。水界的混乱,成为士人们心中世界秩序混乱的类比,进而与现实中的奸臣、朝廷权威问题相重合,激发了诗人们“斩龙”“驱龙”的愿望。概而言之,中唐时期诗人们出于自己官僚身份的自我认知以及对朝廷、世界的责任感和自负心,对危及朝廷的淫祀、恶龙等的存在产生了危机感和焦躁感,这种问题意识促使他们将其表现在了诗文作品中。

AIM: To study the mechanisms by which oridonin inhibited HeLa cell growth in vitro. METHODS: Viability oforidonin-induced HeLa cells was measured by MTT assay. Apoptotic cells with condensed nuclei were visualizedby phase contrast microscopy. Nucleosomal DNA fragmentation was assayed by agarose gel *** activity was assayed using fluorometric protease assay. ICAD, Bcl-2, and Bax proteins expression weredetected by Western blot analysis. RESULTS: Oridonin induced oligonucleosomal fragmentation of DNA andincreased caspase-3 activity, on the other hand, reduced the expression of inhibitor of caspase-3-activated DNase(ICAD), a caspase-3 substrate, at 12 h in HeLa cells. Oridonin-induced DNA fragmentation, caspase-3 activationand down-regulation of ICAD expression were effectively inhibited by a caspase-3 inhibitor, z-DEVD-fmk (z-Asp-Glu-Val-Asp-fmk). However, pretreatment with an inhibitor of poly (ADP-ribose) polymerase (PARP), 3, 4-dihydro-5-[4-(1-piperidinyl)butoxy]-1(2H)-isoquinolinone (DPQ), did not suppress oridonin-induced HeLa cell death. Inaddition, oridonin-induced apoptosis was associated with an increase in the expression of the apoptosis inducerBax, and a significant reduction in expression of the apoptosis suppressor Bcl-2 in mitochondria. CONCLUSION:Oridonin induces HeLa cells apoptosis by altering balance of Bcl-2 and Bax protein expression and activation ofcaspase-3/ICAD pathway.

Ladder climbing is a relatively new but practical locomotion style for robots. Unfortunately, due to their size and weight, ladder climbing by human-sized robots developed so far is struggling with the speedup of ladder climbing motion itself. Therefore, in this paper, a new ladder climbing gait for the robot WAREC-1R is proposed by the authors, which is both faster than the former ones and stable. However, to realize such a gait, a point that has to be taken into consideration is the deformation caused by the self-weight of the robot. To deal with this issue, extra hardware (sensor) and software (position and force control) systems and extra time for sensing and calculation were required. For a complete solution without any complicated systems and time only for deformation compensation, limb stiffness improvement plan by the minimal design change of mechanical parts of the robot is also proposed by the authors, with a thorough study about deformation distribution in the robot. With redesigned parts, ladder climbing experiments by WAREC-1R proved that both the new ladder climbing gait and the limb stiffness improvement are successful, and the reduced deformation is very close to the estimated value as well.
