Open Superstring Star as a Continuous Moyal Product with B Field

In this paper, we recast the matter part of the open superstring star in the present of a constant B field. By using a different coordinate representation the matter part of the open superstring star is identified with the continuous Moyal product of functions of anti-commuting variables. Fortunately we find it does not depend on the value of the B field.     

CAP-子群与p-幂零性

设G是有限群。H是G的一个正规子群。P是|H|的一个素因子。P是H的一个Sylow p-子群。若下列条件之一满足。则H是p-幂零：1)P的极大子群都是G的CAP-子群且(|H|，P-1)=1；2)P的二次极大子群都是G的CAP-子群且(|H|，P^2-1)=1。特别地，若进一步假设G／H为P-幂零且(|G|，P-1)=1或(|G|，P^2-1)=1。则G自身亦为P-幂零。     

CONVERGENCE OF CASCADE ALGORITHMS AND SMOOTHNESS OF REFINABLE DISTRIBUTIONS

In this paper, the author at first develops a method to study convergence of the cascade algorithm in a Banach space without stable assumption on the initial (see Theorem 2.1), and then applies the previous result on the convergence to characterizing compactly supported refinable distributions in fractional Sobolev spaces and Holder continuous spaces (see Theorems 3.1, 3.3, and 3.4). Finally the author applies the above characterization to choosing appropriate initial to guarantee the convergence of the cascade algorithm (see Theorem 4.2).     

黄斑星天牛病原菌的初步研究

从甘肃兰州郊区采集的黄斑星天牛(Anoplophora nobilis)僵硬虫尸上分离得到的2株单胞菌株Ftn-1和Ftn-12,形态学和生物学观察表明两个菌株在PSA培养基上培养(24～25℃)96h的菌落直径均为3.2～3.7cm,基物表层的颜色为灰白色,基物为肉色;在米饭培养基上成咖啡色,在Bilai's培养基上气生菌丝稀少,白色.Ftn-1产生大小两种分生孢子,大孢子为32.5～50um,小孢子为7.5～15um×3.75um,小型分生孢子聚成假头状着生在细长的分生孢子梗上,大型分生孢子着生在短粗的瓶梗上,粘胞团为米黄色,厚垣孢子顶生或侧生;Ftn-12也产生大小两种分生孢子,大孢子为50～60um,小孢子10～17.5um×3.75～5um,,粘胞团墨绿色,厚垣孢子顶生或侧生.根据镰胞菌鉴定方法,初步鉴定Ftn-1为茄病镰胞(Fusarium sonalj),Ftn-12为茄病镰胞蓝色变种(Fusarium sonali var.coerleum).     

Surface Gravity on the Horizon of η- ξ Spacetime

We investigate the two methods of defining the surface gravity ,κ on the horizon, which are the metric definition and the definition given by the spacetime conformal method. It is found that the latter is of greater generality. By this method, we find that ,κ of η- ξ spacetime is equal to the exponent factor α in the coordinate transformation, which confirms the argument that η- ξ spacetime can be considered as the background spacetime for finitetemperature field theories. The reasons why the metric definition of ,κ can not be applied in η- ξ spacetime are presented.
