Based on the scaling idea of local slopes by Lopez et al. [Phys. Rev. Lett. 94 （2005） 166103], we investigate anomalous dynamic scaling of （d ＋ 1）-dimensional surface growth equations with spatially and temporally correlated noise. The growth equations studied include the Kardar-Parisi-Zhang （KPZ）, Sun-Guo-Grant （SGG）, and Lai-Das Sarma-Villain （LDV） equations. The anomalous scaling exponents in both the weak- and strong-coupling regions are obtained, respectively.

以PbO、MgO和Nb_(2)O_(5)为原料,加入KOH作为矿化剂,利用水热法在较低的温度下合成铌镁酸铅粉末,然后在不同的温度下烧结得到了铌镁酸铅陶瓷,用X射线衍射对铌镁酸铅粉体和陶瓷的晶体结构进行表征和分析;用扫描电镜观测铌镁酸铅粉体和陶瓷的形貌及晶粒尺寸,并测试了在不同的温度下,铌镁酸铅陶瓷的介电性能与频率的关系。结果表明:用水热法得到了钙钛矿结构PMN粉体;在SEM图中观察到PMN粉体中晶粒呈尺寸不同的长方体棒状形,晶粒尺寸小于1μm。高温烧结得到铌镁酸铅陶瓷没有发生相变。随频率的增加,铁电相变温度从-7℃移动到7℃。当频率为1 kHz,介电常数的最大值为10672,介电损耗低于0.09。在同一温度下,随频率的升高,介电常数和介电损耗下降。当温度升高时,介电常数增加,同时介电损耗也增加。

To solve the problem of data recovery on free disk sectors, an approach of data recovering based on intelligent pattern matching is proposed in this paper. Different from the methods based on the file directory, this approach utilizes the consistency among the data on the disk. A feature pattern library is established based on different types of fries according to the internal constructions of text. Data on sectors will be classified automatically by data clustering and evaluating. When the conflict happens on data classification, the digestion will be initiated by adopting context pattern. Based on this approach, the paper achieved the data recovery system aiming at pattern matching of txt, word and PDF fries. Raw and formatting recovery tests proved that the system works well.

Genetic expression of chimeric antigen receptors (CAR) enables T cells to target and kill cancer cells in an MHCindependent manner, resulting in a potent antitumor response [1]. To date, more than 10 CAR-T cell products have been approved globally for the treatment of hematologic disorders such as relapsed/refractory B-cell acute lymphoblastic leukemia, non-Hodgkin lymphoma, and multiple myeloma [2,3].

Terminalia catappa L. leaves have been shown to protect against acute liver injury produced by some hepatotoxicants, but the active components and mechanisms are not clear. This study was designed to characterize the protective effects of the chloroform fraction of the ethanol extract of T. catappa leaves (TCCE) against carbon tetrachloride (CCl4)-induced hepatotoxicity in mice, and analyze the changes in expression level of interleukin-6 (IL-6) in the process. It was found that TCCE pretreatment (10 or 30 mg/kg, ig) protected mice from CCl4 toxicity, as evidenced by the reversed alterations in serum alanine aminotrans-ferase (sALT) and serum aspartate aminotransferase (sAST) activities. Additionally liver tissues were subjected to RT-PCR, Western blot and immunohistochemistry to analyze changes in IL-6 expression. It was found that TCCE markedly suppressed the CCl4-induced over-transcription of IL-6 gene. Consistent with the result, the expression of IL-6 protein was also blocked by TCCE in CCl4-stimula

The Er-single-doped and Er/Ce-codoped La3Ga5SiO14 polycrystalline powders are synthesized by the solid-phase synthesis method. The room-temperature luminescence spectra of the samples are investigated. The Near-infrared- region spectroscopic properties of Er3＋ ions in the La3GasSiO14 systems are analysed with Judd-Ofelt theory and rate equations. The effective deactivating effect of Ce3＋ ions on Er3＋ ions is confirmed.
