We investigated the hydroxyl and saponification values of 27 samples of Polysorbate 60 products that were commercially available worldwide. We observed that the values of most of the studied samples were not within the range established at the Joint FAO/WHO Expert Committee on Food Additives (JECFA), while they did agree with the specifications described in the USA, the EU and Japan. We believe that purities of the new commercial Polysorbate 60 samples are higher than those of the older products which were available when the JECFA specifications were discussed (around 1973). The present study suggests that the hydroxyl and saponification values of the current JECFA specifications for Polysorbate 60 should be re-evaluated.

In China, the real industrialization and modernization process started in 1949, when the Chinese people were emancipated from the yoke of the Kuomintang and the People's Republic of China (P.R.C) was founded. However, the road of emancipation has been a bumpy one. In particular, the emancipation of the mind has often been full of twists and turns. The tremendous liberation of social productive forces originated in the emancipation of the mind, whose truth has been tested by economic development practices. In the past 60 years China has paid tremendous efforts and costs in pursuit of emancipation, and today it still needs to emancipate the mind anew. For 60 years, since the formation of P.R. C, the country has kept pursuing the emancipation of the mind while exploring ways of change in institution, strategy and policy. In the first 30 years China attempted to devise an idealistic approach of transition to the socialist planned economic system, which was characterized by continuous revolution and movement. In the second 30 years China explored a realistic approach of transition to the socialist market economic system, which is characterized by incremental reform and opening-up. For six decades industry has remained at the forefront of transformation. The emancipation of the mind and the realization of change aim to ultimately make China a strong nation with an affluent people. The purpose of the six-decade struggle in new China is to erase the stigma of "being poor and blank," secure a firm and strong foothold in the world, restore China's status as a world power and let the Chinese people enjoy the affluence and welfare of a well-off society. The central mission of this national revitalization is to realize industrialization. Therefore, industrialization has been the central theme of China's revitalization in the past 60 years. After 60 years of industrialization, hundreds of millions of Chinese people are now able to enjoy ever-increasing wealth from industrial civilization. However, still a larger proportion of

目前,60 GHz毫米波通信标准(802.***.ad,802.15.3c)中采用基于码本的波束成形技术,其性能仍有提升空间且在天线数较大时,搜索复杂度较高。该文基于以上两点提出了一种贪婪迭代的波束成形方法。首先寻找最佳分区中的中心波束作为初值,然后逐次在每根天线上选取移相器可能取值(1,-1,i,-i)中的最优值作为权重值,最后在收发端进行迭代,直至算法收敛。仿真表明,该方法不仅能够获得更高的频谱效率,同时具有线性复杂度,在毫米波阵列天线数较多时具有较大的优势。

In autodigestion assays, endonuclease activity in non apoptotic HL 60 promyelocytic leukemia cell nuclei cleaved the chromatin of the autologous cells to an oligonucleosomal length pattern. Both EGTA and EDTA inhibited the activation of endonuclease activity in isolated HL 60 cell nuclei. The inhibition by EDTA could be reversed by exogenous Ca 2+ , but not by exogenous Mg 2+ . In Ca 2+ /Mg 2+ free nuclei digestion buffer, addition of Ca 2+ （1\10 mmol/L） induced endonuclease activity in the isolated nuclei, while addition of Mg 2+ had no effect. In the presence of Ca 2+ （0.1 mmol/L）, endonuclease activity was enhanced by exogenous Mg 2+ （0.1\10 mmol/L）. These results suggest that the endonuclease responsible for internucleosomal DNA fragmentation in HL 60 cells during apoptosis is activated by Ca 2+ and further modulated by Mg 2+ in the presence of Ca 2+ .

The 60 years of China’s financial development has been divided into two phases,the planned economy and reform and opening-up.During the planned economy,monetary finance policy strongly supported rapid development of the national economy,as indicated by the significantly higher growth rates in monetary and credit than in major economic indicators of the national economy.During the 30 years of reform and opening-up,China’s financial system developed at a super-normal pace,establishing relatively complete and sound financial institutions and market systems,and continuously pushing forward the process of rule of law and financial internationalization. The 60 years of development in China's financial system have embarked on a path different from the West’s.The following are the valuable experiences learned from China's financial development: 1)Consistently put development as the top priority,and promote development through reform; 2)Adhere to the general principle of financial stability,and proceed from China’s reality; 3)Promote financial development surrounding the real economy; 4)Put forward financial innovation in an appropriate manner; 5)Guard against and defuse financial risks,and adhere to the principal of gradual and orderly opening-up. Amid complex domestic and international economic and financial situations,China needs to improve its regulatory mechanism of monetary policy and its financial market system,deepen the reform of financial institutions,and improve the financial regulatory system so as to make greater achievements.

针对60 GHz信号在非视距(NLOS)环境下测距困难的问题,提出一种基于波束成形的60 GHz无线局域网络(WLAN)定位算法。首先,通过借助波束成形技术进行最强路径搜索,波束成形算法将天线的最大增益方向指向接收最强多径信号的方向,在增强搜索鲁棒性的同时扩大了定位覆盖范围;然后,对NLOS条件下的时延偏差进行建模,重构NLOS测量数据;最后,为进一步提高定位精度,设置检测阈值,引入异常值检测机制。采用Matlab仿真平台在STAs-STAs信道模型进行仿真,结果表明,NLOS环境下基于传统相干估计的到达时间(TOA)定位算法的定位误差约为2 m,定位成功率仅为0.5%,而采用基于波束成形的60 GHz定位算法后,定位误差降低至1.02 cm,定位成功率高达94%。因此,波束成形技术为NLOS环境下的60 GHz定位提供了解决思路,有效地提高了60 GHz室内定位精度和定位成功率。

Helicobacter pylori, the major cause of gastritis, peptic ulcer and gastric cancer, infects half of the world population, but only a few infections lead to serious disease. In order to investigate specific proteins related to the pathogenic difference of this bacterium, comparative proteome analyses of Helicobacter pylori C1 (isolated from patients with gastric cancer) and G1 (isolated from patients with gastritis) were performed using two-dimensional gel electrophoresis (2-DE) and matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF MS). Four proteins (inorganic pyrophosphatase, 3-oxoadipate CoA-transferase subunit B, translation elongation factor, and aldo-keto reductase) were found only in Helicobacter pylori C1, and one protein (alkyl hydroperoxide reductase) was found in G1. Additionally, different isoelectric points (pI) of Hsp60 were observed from the two strains. Then we cloned and sequenced Hsp60 genes from forty-nine Helicobacter pylori isolated from gastric cancer and gastritis. Gene sequencing showed that one C→G single nucleotide polymorphism occurred in the 1399th nucleotide of Hsp60. These results indicate that pathogenic differences exist in various Helicobacter pylori isolated from Chinese patients.

针对移动机器人平台下60 GHz无线信号太弱而无法存在于高衰减的长距离或非直线环境的问题,提出了一种基于自适应缓冲控制的分布式鲁棒多跳路由算法。该算法的核心思想是通过求解单位时间平均预期功耗总和最小化和每单位时隙缓冲稳定性的联合随机优化来确定功率分配量,使每个机器人平台能够计算从它自己的缓冲区传输数据包的功率分配量,从而优化整个系统。拥有二十个移动监控机器人平台的仿真实验验证了提出算法的有效性。实验结果表明,相比分布式多跳路由协议中较为著名的自组织网络按需距离向量(AODV)算法,提出的算法在平均功耗和缓冲占有率方面均有优势,在权重因子为0.5和2时,缓冲占有率分别为AODV的0.14和0.34倍,平均功耗也有所降低。
