清醒的扑火飞蛾--从《夜莺与蔷薇》看王尔德的矛盾性

长期以来,奥斯卡·王尔德被公认为是充满矛盾性的唯关主义的代表人物.童话<夜莺与蔷薇>就成功地反映出了王尔德的唯美主义理论及其对自身理论的反思与困惑.王尔德对世界进行的艺术世界与现实世界的二元划分,对脱离生活的纯粹艺术的追求,是造成其矛盾性的根源.

设ζ(s,α)为HurwitzZeta函数.当Re(s)>1时,定义ζ(s,α)=∑∞n=01(n+α)s(实数α>0),ζ′(s,α)、ζ″(s,α)分别表示关于复变量s的一阶导数、二阶导数.利用解析方法及三角和估计给出了ζ(s,α)对参数α的积分均值的一些有趣的渐近公式.     

Function analysis of a semi-dwarf sdg in rice with near isogenic lines

The physiological phenotype of the rice semi-dwarf mutant,sdg,was characterized in details using a pair of near isogenic .Neither gibberellin*deficient nor gibberellin-insensitive is characteristic of the sdgphenotype.Byanalyzing the secretion of aamylas and the promotion of stem growth caused by eogenous gibberellin(GA),the sdg plant was found to have decreased sensitivity to the GA at the seedling stage. The dwarfism stature of the sdg mutant can be attributed to the shortened internodes. Increase of the cell sults indicate the protein encded by the wild type gene of sdg may be a regulator for cell elogation.     

Poly(dimethylsiloxane) based microchip for DNA electrophoresis

A novel poly(dimethylsiloxane)(PDMS) -based microchip for DNA separation through electrophoresis has been developed using a micro-electro-mechanical-system(MEMS) technology. Unlike previous hybrid PDMS microchip, one PDMS film is first created on glass support by pressing method in our microchip. Thus, increased band-broadening phenomena, arising from the material nonuniformity at the walls of microchannel, can be avoided in electrophoresis process. A low-viscosity hydroxypropylmethylcellulose-100 (HPMC-100) is used as the separation medium for fluorescent intercalator-labeled double-stranded DNA (dsDNA) fragments. Mannitol is introduced to PDMS-based microchip as a separation medium additive to enhance separation efficiency. At applied electric field strength of 150 V/cm, excellent separations of the PCR marker could be achieved with an effective separation distance of 25mm .     

Multiple change-points estimation of moving-average processes under dependence assumptions

In this paper, some results of convergence for a least-square estimator in the problem of multiple change-points estimation are presented and the moving-average processes of ρ-mixing sequence in the mean shifts are discussed. When the number of change points is known, the consistency of change-points estimator is derived. When the number of changes is unknown, the consistency of the change-points number and the change-points estimator by penalized least-squares method are obtained. The results are also true for φ-mixing, α-mixing, associated and negative associated sequences under suitable conditions.
